Is hematopoietic stem cell transplant linked to neurotoxicity in MS?
Key clinical point: Study finds direct evidence of transient neurotoxicity immediately after immunoablative autologous hematopoietic stem cell transplantation (IAHSCT) for aggressive multiple sclerosis (MS).
Major finding: Three months post-IAHSCT, levels of serum markers of both neuroaxonal and glial cell injury (serum Neurofilament Light Chain [sNfL] and serum Glial Fibrillary Acidic Protein [sGFAP]) increased from baseline by 32.1% (P = .029) and 74.8% (P = .0004), respectively. sNfL increases correlated with the dose of busulfan administered during transplant conditioning (P = .034), Expanded Disability Status Scale score (P = .041), as well as brain volume loss (P = .044), attributed to gray matter loss (P = .0023).
Study details: sNfL and sGFAP levels were evaluated pre- and post-IAHSCT at 3, 6, 9, and 12 months in 22 patients with MS and 28 noninflammatory control participants.
Disclosures: The study was funded by the MS Society of Canada. The authors declared no conflict of interest.

WHO: Asymptomatic COVID-19 spread deemed ‘rare’
An official with the World Health Organization (WHO) has stated that it appears to be “rare” that an asymptomatic individual can pass SARS-CoV-2 to someone else.
“From the data we have, it still seems to be rare that an asymptomatic person actually transmits onward to a secondary individual,” Maria Van Kerkhove, PhD, WHO’s COVID-19 technical lead and an infectious disease epidemiologist, said June 8 at a news briefing from the agency’s Geneva headquarters.
This announcement came on the heels of the publication of an analysis in the Annals of Internal Medicine, which suggested that as many as 40-45% of COVID-19 cases may be asymptomatic. In this paper, the authors, Daniel P. Oran, AM, and Eric J. Topol, MD, of the Scripps Research Translational Institute in La Jolla, Calif stated: “The likelihood that approximately 40%-45% of those infected with SARS-CoV-2 will remain asymptomatic suggests that the virus might have greater potential than previously estimated to spread silently and deeply through human populations.”
"The early data that we have assembled on the prevalence of asymptomatic SARS-CoV-2 infection suggest that this is a significant factor in the rapid progression of the COVID-19 pandemic," the authors concluded.
Dr. Van Kerkhove also made comments suggesting otherwise on Twitter, citing a new summary by WHO: “@WHO recently published a summary of transmission of #COVID19, incl. symptomatic, pre-symptomatic and asymptomatic transmission.”
She also tweeted the following lines from the WHO summary: “Comprehensive studies on transmission from asymptomatic individuals are difficult to conduct, but the available evidence from contact tracing reported by Member States suggests that asymptomatically-infected individuals are much less likely to transmit the virus than those who develop symptoms.”
In an additional post, Dr. Van Kerkhove added: “In these data, it is important to breakdown truly asymptomatic vs pre-symptomatic vs mildly symptomatic... also to note that the [percentage] reported or estimated to be ‘asymptomatic’ is not the same as the [percentage] that are asymptomatic that actually transmit.”
In the paper published in the Annals of Internal Medicine, Mr. Oran and Dr. Topol analyzed data of asymptomatic individuals from 16 cohorts between April 19 and May 26, 2020 – a wide-ranging group consisting of residents of cities, health care workers, individuals in homeless shelters, obstetric patients, residents of a nursing home, crew members of aircraft carriers, passengers on cruise ships, and inmates in correctional facilities. Each cohort had varying rates of asymptomatic or presymptomatic cases..
When residents of Iceland were tested, 43 of 100 individuals who tested positive for SARS-CoV-2 did not show symptoms. In Vo’, Italy, 30 of 73 people (41.1%) with positive SARS-CoV-2 test results did not have symptoms in a first round of testing, and 13 of 29 (44.8%) had no symptoms in a second round of testing. Over half of residents of San Francisco’s Mission District who received testing (39 of 74; 52.7%) did not have symptoms, while slightly less than half of Indiana residents tested showed no symptoms (35 of 78; 44.8%).
A majority of 41 individuals (65.9%) who were mostly health care workers at Rutgers University reported no symptoms of COVID-19 at the time of testing. Data from homeless shelters in Boston (129 of 147; 87.7%) and Los Angeles (27 of 43; 62.7%) also showed a high rate of individuals without symptoms. Among 33 obstetric patients in New York City who tested positive for SARS-CoV-2, 29 women (87.9%) were asymptomatic during a median 2-day length of stay. In a Washington state nursing facility, 12 of 23 individuals (52.1%) were positive for SARS-CoV-2 without showing symptoms in a first round of testing, with another 15 of 24 residents (62.5%) not showing symptoms in a second round of testing. Of these residents, 24 individuals (88.9%) later went on to show symptoms of COVID-19.
Most of the 783 Greek citizens who tested positive for SARS-CoV-2 after being evacuated from Spain, Turkey, and the United Kingdom showed no symptoms of COVID-19 (35 of 40; 87.5%). A group of 565 Japanese citizens evacuated from Wuhan, China, had a lower number of cases without initial symptoms – 13 people were positive for SARS-CoV-2, and 4 of 13 (30.8%) had no symptoms.
In closed cohorts, there appeared to also be a high rate of COVID-19 cases without initial symptoms. Of 3,277 inmates from correctional facilities in Arkansas, North Carolina, Ohio, and Virginia, 3,146 individuals (96%) had no symptoms at the time of testing. There was also a large percentage of passengers and crew of the Diamond Princess cruise ship (331 of 712; 46.5%) and an Argentine cruise ship (104 of 128; 81.3%) who were positive for SARS-CoV-2 without symptoms. On the aircraft carrier U.S.S. Theodore Roosevelt, 60% of 856 individuals, while on the French aircraft carrier Charles de Gaulle, nearly 50% of individuals were asymptomatic.
It is difficult to tell the difference between people who are presymptomatic and will later go on to develop symptoms of COVID-19 and those who will remain asymptomatic. “The simple solution to this conundrum is longitudinal testing – that is, repeated observations of the individual over time,” but only 5 of 16 cohorts studied had longitudinal data on individuals, Mr. Oran and Dr. Topol said.
Seth Trueger, MD, an emergency physician and assistant professor of emergency medicine at Northwestern University, Chicago, who was not involved in the study, said it was important to see this information all in one place, even if the data isn’t new.
“I think we’ve certainly kind of seen from the beginning there’s some level of asymptomatic and presymptomatic spread,” Dr. Trueger said. “In health care, we’ve been lucky to get those lessons early on and start to think of things like universal masking in hospitals, and unfortunate things like limiting visitors.”
A more nuanced understanding of how SARS-CoV-2 spreads has been difficult to capture, in part because of operating under a shortened time frame and handicapped testing capacity, he noted. “[Even] in the best of possible circumstances, trying to figure out epidemiology in people who don’t have symptoms is really tough,” Dr. Truegar said.
“Even the best studies are still relatively decent samples, and not totally representative,” he added.
Another limitation to capturing accurate data is method of testing. Real-time reverse transcriptase polymerase chain reaction using nasopharyngeal swabs can detect RNA fragments from SARS-CoV-2, which could potentially affect the results. “It’s really hard to know what is actually infected virus versus just fragments of RNA that make the test positive,” Dr. Trueger said.
If the rate of asymptomatic cases is higher than previously thought, it’s a “double-edged sword,” he noted. It may mean the infection fatality rate is lower than predicted, but “even at high levels of what we think community levels might be, we’re far from herd immunity.”
The study authors and Dr. Trueger reported no relevant conflicts of interest.

FROM ANNALS OF INTERNAL MEDICINE
Analysis of Pharmacist Interventions Used to Resolve Safety Target of Polypharmacy (STOP) Drug Interactions
Statins are one of the most common medications dispensed in the US and are associated with clinically significant drug interactions.1,2 The most common adverse drug reaction (ADR) of statin drug interactions is muscle-related toxicities.2 Despite technology advances to alert clinicians to drug interactions, updated statin manufacturer labeling, and guideline recommendations, inappropriate prescribing and dispensing of statin drug interactions continues to occur in health care systems.2-10
The medical literature has demonstrated many opportunities for pharmacists to prevent and mitigate drug interactions. At the points of prescribing and dispensing, pharmacists can reduce the number of potential drug interactions for the patient.11-13 Pharmacists also have identified and resolved drug interactions through quality assurance review after dispensing to a patient.7,8
Regardless of the time point of an intervention, the most common method pharmacists used to resolve drug interactions was through recommendations to a prescriber. The recommendations were generated through academic detailing, clinical decision support algorithms, drug conversions, or the pharmacist’s expertise. Regardless of the method the pharmacist used, the prescriber had the final authority to accept or decline the recommendation.7,8,11-13 Although these interventions were effective, pharmacists could further streamline the process by autonomously resolving drug interactions. However, these types of interventions are not well described in the medical literature.
Background
The US Department of Veterans Affairs (VA) Veterans Integrated Service Network (VISN), established the Safety Target of Polypharmacy (STOP) report in 2015. At each facility in the network, the report identified patients who were dispensed medications known to have drug interactions. The interactions were chosen by the VISN, and the severity of the interactions was based on coding parameters within the VA computerized order entry system, which uses a severity score based on First Databank data. At the Harry S. Truman Memorial Veterans’ Hospital (Truman VA) in Columbia, Missouri, > 500 drug interactions were initially active on the STOP report. The most common drug interactions were statins with gemfibrozil and statins with niacin.14-18 The Truman VA Pharmacy Service was charged with resolving the interactions for the facility.
The Truman VA employs 3 Patient Aligned Care Team (PACT) Clinical Pharmacy Specialists (CPS) practicing within primary care clinics. PACT is the patientcentered medical home model used by the VA. PACT CPS are ambulatory care pharmacists who assist providers in managing diseases using a scope of practice. Having a scope of practice would have allowed the PACT CPS to manage drug interactions with independent prescribing authority. However, due to the high volume of STOP report interactions and limited PACT CPS resources, the Pharmacy Service needed to develop an efficient, patient-centered method to resolve them. The intervention also needed to allow pharmacists, both with and without a scope of practice, to address the interactions.
Methods
The Truman VA Pharmacy Service developed protocols, approved by the Pharmacy and Therapeutics (P&T) Committee, to manage the specific gemfibrozil-statin and niacinstatin interactions chosen for the VISN 15 STOP report (Figures 1 and 2). The protocols were designed to identify patients who did not have a clear indication for gemfibrozil or niacin, were likely to maintain triglycerides (TGs) < 500 mg/dL without these medications, and would not likely require close monitoring after discontinuation.19 The protocols allowed pharmacists to autonomously discontinue gemfibrozil or niacin if patients did not have a history of pancreatitis, TGs ≥ 400 mg/dL or a nonlipid indication for niacin (eg, pellagra) after establishing care at Truman VA. Additionally, both interacting medications had to be dispensed by the VA. When pharmacists discontinued a medication, it was documented in a note in the patient electronic health record. The prescriber was notified through the note and the patient received a notification letter. Follow-up laboratory monitoring was not required as part of the protocol.
If patients met any of the exclusion criteria for discontinuation, the primary care provider (PCP) was notified to place a consult to the PACT Pharmacy Clinic for individualized interventions and close monitoring. Patients prescribed niacin for nonlipid indications were allowed to continue with their current drug regimen. At each encounter, the PACT CPS assessed for ADRs, made individualized medication changes, and arranged follow-up appointments. Once the interaction was resolved and treatment goals met, the PCP resumed monitoring of the patient’s lipid therapy.
Following all pharmacist interventions, a retrospective quality improvement analysis was conducted. The primary outcome was to evaluate the impact of discontinuing gemfibrozil and niacin by protocol on patients’ laboratory results. The coprimary endpoints were to describe the change in TG levels and the percentage of patients with TGs ≥ 500 mg/dL at least 5 weeks following the pharmacist-directed discontinuation by protocol. Secondary outcomes included the time required to resolve the interactions and a description of the PACT CPS pharmacologic interventions. Additionally, a quality assurance peer review was used to ensure the pharmacists appropriately utilized the protocols.
Data were collected from August 2016 to September 2017 for patients prescribed gemfibrozil and from May 2017 to January 2018 for patients prescribed niacin. The time spent resolving interactions was quantified based on encounter data. Descriptive statistics were used to analyze demographic information and the endpoints associated with each outcome. The project was reviewed by the University of Missouri Institutional Review Board, Truman VA privacy and information security officers, and was determined to meet guidelines for quality improvement.
Results
The original STOP report included 397 drug interactions involving statins with gemfibrozil or niacin (Table 1). The majority of patients were white and male aged 60 to 79 years. Gemfibrozil was the most common drug involved in all interactions (79.8%). The most common statins were atorvastatin (40%) and simvastatin (36.5%).
Gemfibrozil-Statin Interactions
Pharmacists discontinued gemfibrozil by protocol for 94 patients (29.6%), and 107 patients (33.8%) were referred to the PACT Pharmacy Clinic (Figure 3). For the remaining 116 patients (36.6%), the drug interaction was addressed outside of the protocol for the following reasons: the drug interaction was resolved prior to pharmacist review; an interacting prescription was expired and not to be continued; the patient self-discontinued ≥ 1 interacting medications; the patient was deceased; the patient moved; the patient was receiving ≥ 1 interacting medications outside of the VA; or the prescriber resolved the interaction following notification by the pharmacist.
Ultimately, the interaction was resolved for all patients with a gemfibrozil-statin interaction on the STOP report. Following gemfibrozil discontinuation by protocol, 76 patients (80.9%) had TG laboratory results available and were included in the analysis. Sixty-two patients’ (82%) TG levels decreased or increased by < 100 mg/dL (Figure 4), and the TG levels of 1 patient (1.3%) increased above the threshold of 500 mg/dL. The mean (SD) time to the first laboratory result after the pharmacists mailed the notification letter was 6.5 (3.6) months (range, 1-17). The pharmacists spent a mean of 16 minutes per patient resolving each interaction.
Of the 107 patients referred to the PACT Pharmacy Clinic, 80 (74.8%) had TG laboratory results available and were included in the analysis. These patients were followed by the PACT CPS until the drug interaction was resolved and confirmed to have TG levels at goal (< 500 mg/dL). Gemfibrozil doses ranged from 300 mg daily to 600 mg twice daily, with 70% (n = 56) of patients taking 600 mg twice daily. The PACT CPS made 148 interventions (Table 2). Twenty-three (29%) patients required only gemfibrozil discontinuation. The remaining 57 patients (71%) required at least 2 medication interventions. The PACT CPS generated 213 encounters for resolving drug interactions with a median of 2 encounters per patient.
Quality assurance review identified 5 patients (5.3%) who underwent gemfibrozil discontinuation by protocol, despite having criteria that would have recommended against discontinuation. In accordance with the protocol criteria, these patients were later referred to the PACT Pharmacy Clinic. None of these patients experienced a TG increase at or above the threshold of 500 mg/dL after gemfibrozil was initially discontinued but were excluded from the earlier analysis.
Niacin-Statin Interactions
Pharmacists discontinued niacin by protocol for 48 patients (60.0%), and 22 patients (27.5%) were referred to the PACT Pharmacy Clinic (Figure 5). For the remaining 5 patients (6.3%), the interaction was either addressed outside the protocol prior to pharmacist review, or an interacting prescription was expired and not to be continued. Additionally, niacin was continued per prescriber preference in 5 patients (6.3%).
Thirty-six patients (75%) had TG laboratory results available following niacin discontinuation by protocol and were included in the analysis. Most patients’ (n = 33, 91.7%) TG levels decreased or increased by < 100 mg/dL. No patient had a TG level that increased higher than the threshold of 500 mg/dL. The mean (SD) time to the first laboratory result after the pharmacists mailed the notification letter, was 5.3 (2.5) months (range, 1.2-9.8). The pharmacists spent a mean of 15 minutes per patient resolving each interaction. The quality assurance review found no discrepancies in the pharmacists’ application of the protocol.
Of the 22 patients referred to the PACT Pharmacy Clinic, 16 (72.7%) patients had TG laboratory results available and were included in the analysis. As with the gemfibrozil interactions, these patients were followed by the PACT Pharmacy Clinic until the drug interaction was resolved and confirmed to have TGs at goal (< 500 mg/dL). Niacin doses ranged from 500 mg daily to 2,000 mg daily, with the majority of patients taking 1,000 mg daily. The PACT CPS made 23 interventions. The PACT CPS generated 46 encounters for resolving drug interactions with a median of 2 encounters per patient.
Discussion
Following gemfibrozil or niacin discontinuation by protocol, most patients with available laboratory results experienced either a decrease or modest TG elevation. The proportion of patients experiencing a decrease in TGs was unexpected but potentially multifactorial. Individual causes for the decrease in TGs were beyond the scope of this analysis. The retrospective design limited the ability to identify variables that could have impacted TG levels when gemfibrozil or niacin were started and discontinued. Although the treatment of TG levels is not indicated until it is ≥ 500 mg/dL, due to an increased risk of pancreatitis, both protocols excluded patients with a history of TGs ≥ 400 mg/dL.19 The lower threshold was set to compensate for anticipated increase in TG levels, following gemfibrozil or niacin discontinuation, and to minimize the number of patients with TG levels ≥ 500 mg/dL. The actual impact on patients’ TG levels supports the use of this lower threshold in the protocol.
When TG levels increased by 200 to 249 mg/dL after gemfibrozil or niacin discontinuation, patients were evaluated for possible underlying causes, which occurred for 4 gemfibrozil and 1 niacin patient. One patient started a β-blocker after gemfibrozil was initiated, and 3 patients were taking gemfibrozil prior to establishing care at the VA. The TG levels of the patient taking niacin correlated with an increased hemoglobin A1c. The TG level for only 1 patient taking gemfibrozil increased above the 500 mg/dL threshold. The patient had several comorbidities known to increase TG levels, but the comorbidities were previously well controlled. No additional medication changes were made at that time, and the TG levels on the next fasting lipid panel decreased to goal. The patient did not experience any negative clinical sequelae from the elevated TG levels.
Thirty-five patients (36%) who were referred to the PACT Pharmacy Clinic required only either gemfibrozil or niacin discontinuation. These patients were evaluated to identify whether adjustments to the protocols would have allowed for pharmacist discontinuation without referral to the PACT Pharmacy Clinic. Twenty-four of these patients (69%) had repeated TG levels ≥ 400 mg/dL prior to referral to the PACT Pharmacy Clinic. Additionally, there was no correlation between the gemfibrozil or niacin doses and the change in TG levels following discontinuation. These data indicate the protocols appropriately identified patients who did not have an indication for gemfibrozil or niacin.
In addition to drug interactions identified on the STOP report, the PACT CPS resolved 12 additional interactions involving simvastatin and gemfibrozil. Additionally, unnecessary lipid medications were deprescribed. The PACT CPS identified 13 patients who experienced myalgias, an ADR attributed to the gemfibrozil- statin interaction. Of those, 9 patients’ ADRs resolved after discontinuing gemfibrozil alone. For the remaining 4 patients, additional interventions to convert the patient to another statin were required to resolve the ADR.
Using pharmacists to address the drug interactions shifted workload from the prescribers and other primary care team members. The mean time spent to resolve both gemfibrozil and niacin interactions by protocol was 15.5 minutes. One hundred fortytwo patients (35.8%) had drug interactions resolved by protocol, saving the PACT CPS’ expertise for patients requiring individualized interventions. Drug interactions were resolved within 4 PACT CPS encounters for 93.8% of the patients taking gemfibrozil and within 3 PACT CPS encounters for 93.8% of the patients taking niacin.
The protocols allowed 12 additional pharmacists who did not have an ambulatory care scope of practice to assist the PACT CPS in mitigating the STOP drug interactions. These pharmacists otherwise would have been limited to making consultative recommendations. Simultaneously, the design allowed for the PACT pharmacists’ expertise to be allocated for patients most likely to require interventions beyond the protocols. This type of intraprofessional referral process is not well described in the medical literature. To the authors’ knowledge, the only studies described referrals from hospital pharmacists to community pharmacists during transitions of care on hospital discharge.20,21
Limitations
The results of this study are derived from a retrospective chart review at a single VA facility. The autonomous nature of PACT CPS interventions may be difficult to replicate in other settings that do not permit pharmacists the same prescriptive authority. This analysis was designed to demonstrate the impact of the pharmacist in resolving major drug interactions. Patients referred to the PACT Pharmacy Clinic who also had their lipid medications adjusted by a nonpharmacist provider were excluded. However, this may have minimized the impact of the PACT CPS on the patient care provided. As postintervention laboratory results were not available for all patients, some patients’ TG levels could have increased above the 500 mg/dL threshold but were not identified. The time investment was extensive and likely underestimates the true cost of implementing the interventions.
Because notification letters were used to instruct patients to stop gemfibrozil or niacin, several considerations need to be addressed when interpreting the follow-up laboratory results. First, we cannot confirm whether the patients received the letter or the exact date the letter was received. Additionally, we cannot confirm whether the patients followed the instructions to stop the interacting medications or the date the medications were stopped. It is possible some patients were still taking the interacting medication when the first laboratory was drawn. Should a patient have continued the interacting medication, most would have run out and been unable to obtain a refill within 90 days of receiving the letter, as this is the maximum amount dispensed at one time. The mean time to the first laboratory result for both gemfibrozil and niacin was 6.5 and 5.3 months, respectively. Approximately 85% of patients completed the first laboratory test at least 3 months after the letter was mailed.
The protocols were designed to assess whether gemfibrozil or niacin was indicated and did not assess whether the statin was indicated. Therefore, discontinuing the statin also could have resolved the interaction appropriately. However, due to characteristics of the patient population and recommendations in current lipid guidelines, it was more likely the statin would be indicated.22,23 The protocols also assumed that patients eligible for gemfibrozil or niacin discontinuation would not need additional changes to their lipid medications. The medication changes made by the PACT CPS may have gone beyond those minimally necessary to resolve the drug interaction and maintain TG goals. Patients who had gemfibrozil or niacin discontinued by protocol also may have benefited from additional optimization of their lipid medications.
Conclusions
This quality improvement analysis supports further evaluation of the complementary use of protocols and PACT CPS prescriptive authority to resolve statin drug interactions. The gemfibrozil and niacin protocols appropriately identified patients who were less likely to experience an adverse change in TG laboratory results. Patients more likely to require additional medication interventions were appropriately referred to the PACT Pharmacy Clinics for individualized care. These data support expanded roles for pharmacists, across various settings, to mitigate select drug interactions at the Truman VA.

Statins are one of the most common medications dispensed in the US and are associated with clinically significant drug interactions.1,2 The most common adverse drug reaction (ADR) of statin drug interactions is muscle-related toxicities.2 Despite technology advances to alert clinicians to drug interactions, updated statin manufacturer labeling, and guideline recommendations, inappropriate prescribing and dispensing of statin drug interactions continues to occur in health care systems.2-10
The medical literature has demonstrated many opportunities for pharmacists to prevent and mitigate drug interactions. At the points of prescribing and dispensing, pharmacists can reduce the number of potential drug interactions for the patient.11-13 Pharmacists also have identified and resolved drug interactions through quality assurance review after dispensing to a patient.7,8
Regardless of the time point of an intervention, the most common method pharmacists used to resolve drug interactions was through recommendations to a prescriber. The recommendations were generated through academic detailing, clinical decision support algorithms, drug conversions, or the pharmacist’s expertise. Regardless of the method the pharmacist used, the prescriber had the final authority to accept or decline the recommendation.7,8,11-13 Although these interventions were effective, pharmacists could further streamline the process by autonomously resolving drug interactions. However, these types of interventions are not well described in the medical literature.
Background
The US Department of Veterans Affairs (VA) Veterans Integrated Service Network (VISN), established the Safety Target of Polypharmacy (STOP) report in 2015. At each facility in the network, the report identified patients who were dispensed medications known to have drug interactions. The interactions were chosen by the VISN, and the severity of the interactions was based on coding parameters within the VA computerized order entry system, which uses a severity score based on First Databank data. At the Harry S. Truman Memorial Veterans’ Hospital (Truman VA) in Columbia, Missouri, > 500 drug interactions were initially active on the STOP report. The most common drug interactions were statins with gemfibrozil and statins with niacin.14-18 The Truman VA Pharmacy Service was charged with resolving the interactions for the facility.
The Truman VA employs 3 Patient Aligned Care Team (PACT) Clinical Pharmacy Specialists (CPS) practicing within primary care clinics. PACT is the patientcentered medical home model used by the VA. PACT CPS are ambulatory care pharmacists who assist providers in managing diseases using a scope of practice. Having a scope of practice would have allowed the PACT CPS to manage drug interactions with independent prescribing authority. However, due to the high volume of STOP report interactions and limited PACT CPS resources, the Pharmacy Service needed to develop an efficient, patient-centered method to resolve them. The intervention also needed to allow pharmacists, both with and without a scope of practice, to address the interactions.
Methods
The Truman VA Pharmacy Service developed protocols, approved by the Pharmacy and Therapeutics (P&T) Committee, to manage the specific gemfibrozil-statin and niacinstatin interactions chosen for the VISN 15 STOP report (Figures 1 and 2). The protocols were designed to identify patients who did not have a clear indication for gemfibrozil or niacin, were likely to maintain triglycerides (TGs) < 500 mg/dL without these medications, and would not likely require close monitoring after discontinuation.19 The protocols allowed pharmacists to autonomously discontinue gemfibrozil or niacin if patients did not have a history of pancreatitis, TGs ≥ 400 mg/dL or a nonlipid indication for niacin (eg, pellagra) after establishing care at Truman VA. Additionally, both interacting medications had to be dispensed by the VA. When pharmacists discontinued a medication, it was documented in a note in the patient electronic health record. The prescriber was notified through the note and the patient received a notification letter. Follow-up laboratory monitoring was not required as part of the protocol.
If patients met any of the exclusion criteria for discontinuation, the primary care provider (PCP) was notified to place a consult to the PACT Pharmacy Clinic for individualized interventions and close monitoring. Patients prescribed niacin for nonlipid indications were allowed to continue with their current drug regimen. At each encounter, the PACT CPS assessed for ADRs, made individualized medication changes, and arranged follow-up appointments. Once the interaction was resolved and treatment goals met, the PCP resumed monitoring of the patient’s lipid therapy.
Following all pharmacist interventions, a retrospective quality improvement analysis was conducted. The primary outcome was to evaluate the impact of discontinuing gemfibrozil and niacin by protocol on patients’ laboratory results. The coprimary endpoints were to describe the change in TG levels and the percentage of patients with TGs ≥ 500 mg/dL at least 5 weeks following the pharmacist-directed discontinuation by protocol. Secondary outcomes included the time required to resolve the interactions and a description of the PACT CPS pharmacologic interventions. Additionally, a quality assurance peer review was used to ensure the pharmacists appropriately utilized the protocols.
Data were collected from August 2016 to September 2017 for patients prescribed gemfibrozil and from May 2017 to January 2018 for patients prescribed niacin. The time spent resolving interactions was quantified based on encounter data. Descriptive statistics were used to analyze demographic information and the endpoints associated with each outcome. The project was reviewed by the University of Missouri Institutional Review Board, Truman VA privacy and information security officers, and was determined to meet guidelines for quality improvement.
Results
The original STOP report included 397 drug interactions involving statins with gemfibrozil or niacin (Table 1). The majority of patients were white and male aged 60 to 79 years. Gemfibrozil was the most common drug involved in all interactions (79.8%). The most common statins were atorvastatin (40%) and simvastatin (36.5%).
Gemfibrozil-Statin Interactions
Pharmacists discontinued gemfibrozil by protocol for 94 patients (29.6%), and 107 patients (33.8%) were referred to the PACT Pharmacy Clinic (Figure 3). For the remaining 116 patients (36.6%), the drug interaction was addressed outside of the protocol for the following reasons: the drug interaction was resolved prior to pharmacist review; an interacting prescription was expired and not to be continued; the patient self-discontinued ≥ 1 interacting medications; the patient was deceased; the patient moved; the patient was receiving ≥ 1 interacting medications outside of the VA; or the prescriber resolved the interaction following notification by the pharmacist.
Ultimately, the interaction was resolved for all patients with a gemfibrozil-statin interaction on the STOP report. Following gemfibrozil discontinuation by protocol, 76 patients (80.9%) had TG laboratory results available and were included in the analysis. Sixty-two patients’ (82%) TG levels decreased or increased by < 100 mg/dL (Figure 4), and the TG levels of 1 patient (1.3%) increased above the threshold of 500 mg/dL. The mean (SD) time to the first laboratory result after the pharmacists mailed the notification letter was 6.5 (3.6) months (range, 1-17). The pharmacists spent a mean of 16 minutes per patient resolving each interaction.
Of the 107 patients referred to the PACT Pharmacy Clinic, 80 (74.8%) had TG laboratory results available and were included in the analysis. These patients were followed by the PACT CPS until the drug interaction was resolved and confirmed to have TG levels at goal (< 500 mg/dL). Gemfibrozil doses ranged from 300 mg daily to 600 mg twice daily, with 70% (n = 56) of patients taking 600 mg twice daily. The PACT CPS made 148 interventions (Table 2). Twenty-three (29%) patients required only gemfibrozil discontinuation. The remaining 57 patients (71%) required at least 2 medication interventions. The PACT CPS generated 213 encounters for resolving drug interactions with a median of 2 encounters per patient.
Quality assurance review identified 5 patients (5.3%) who underwent gemfibrozil discontinuation by protocol, despite having criteria that would have recommended against discontinuation. In accordance with the protocol criteria, these patients were later referred to the PACT Pharmacy Clinic. None of these patients experienced a TG increase at or above the threshold of 500 mg/dL after gemfibrozil was initially discontinued but were excluded from the earlier analysis.
Niacin-Statin Interactions
Pharmacists discontinued niacin by protocol for 48 patients (60.0%), and 22 patients (27.5%) were referred to the PACT Pharmacy Clinic (Figure 5). For the remaining 5 patients (6.3%), the interaction was either addressed outside the protocol prior to pharmacist review, or an interacting prescription was expired and not to be continued. Additionally, niacin was continued per prescriber preference in 5 patients (6.3%).
Thirty-six patients (75%) had TG laboratory results available following niacin discontinuation by protocol and were included in the analysis. Most patients’ (n = 33, 91.7%) TG levels decreased or increased by < 100 mg/dL. No patient had a TG level that increased higher than the threshold of 500 mg/dL. The mean (SD) time to the first laboratory result after the pharmacists mailed the notification letter, was 5.3 (2.5) months (range, 1.2-9.8). The pharmacists spent a mean of 15 minutes per patient resolving each interaction. The quality assurance review found no discrepancies in the pharmacists’ application of the protocol.
Of the 22 patients referred to the PACT Pharmacy Clinic, 16 (72.7%) patients had TG laboratory results available and were included in the analysis. As with the gemfibrozil interactions, these patients were followed by the PACT Pharmacy Clinic until the drug interaction was resolved and confirmed to have TGs at goal (< 500 mg/dL). Niacin doses ranged from 500 mg daily to 2,000 mg daily, with the majority of patients taking 1,000 mg daily. The PACT CPS made 23 interventions. The PACT CPS generated 46 encounters for resolving drug interactions with a median of 2 encounters per patient.

Statins are one of the most common medications dispensed in the US and are associated with clinically significant drug interactions.1,2 The most common adverse drug reaction (ADR) of statin drug interactions is muscle-related toxicities.2 Despite technology advances to alert clinicians to drug interactions, updated statin manufacturer labeling, and guideline recommendations, inappropriate prescribing and dispensing of statin drug interactions continues to occur in health care systems.2-10
The medical literature has demonstrated many opportunities for pharmacists to prevent and mitigate drug interactions. At the points of prescribing and dispensing, pharmacists can reduce the number of potential drug interactions for the patient.11-13 Pharmacists also have identified and resolved drug interactions through quality assurance review after dispensing to a patient.7,8
Regardless of the time point of an intervention, the most common method pharmacists used to resolve drug interactions was through recommendations to a prescriber. The recommendations were generated through academic detailing, clinical decision support algorithms, drug conversions, or the pharmacist’s expertise. Regardless of the method the pharmacist used, the prescriber had the final authority to accept or decline the recommendation.7,8,11-13 Although these interventions were effective, pharmacists could further streamline the process by autonomously resolving drug interactions. However, these types of interventions are not well described in the medical literature.
Background
The US Department of Veterans Affairs (VA) Veterans Integrated Service Network (VISN), established the Safety Target of Polypharmacy (STOP) report in 2015. At each facility in the network, the report identified patients who were dispensed medications known to have drug interactions. The interactions were chosen by the VISN, and the severity of the interactions was based on coding parameters within the VA computerized order entry system, which uses a severity score based on First Databank data. At the Harry S. Truman Memorial Veterans’ Hospital (Truman VA) in Columbia, Missouri, > 500 drug interactions were initially active on the STOP report. The most common drug interactions were statins with gemfibrozil and statins with niacin.14-18 The Truman VA Pharmacy Service was charged with resolving the interactions for the facility.
The Truman VA employs 3 Patient Aligned Care Team (PACT) Clinical Pharmacy Specialists (CPS) practicing within primary care clinics. PACT is the patientcentered medical home model used by the VA. PACT CPS are ambulatory care pharmacists who assist providers in managing diseases using a scope of practice. Having a scope of practice would have allowed the PACT CPS to manage drug interactions with independent prescribing authority. However, due to the high volume of STOP report interactions and limited PACT CPS resources, the Pharmacy Service needed to develop an efficient, patient-centered method to resolve them. The intervention also needed to allow pharmacists, both with and without a scope of practice, to address the interactions.
Methods
The Truman VA Pharmacy Service developed protocols, approved by the Pharmacy and Therapeutics (P&T) Committee, to manage the specific gemfibrozil-statin and niacinstatin interactions chosen for the VISN 15 STOP report (Figures 1 and 2). The protocols were designed to identify patients who did not have a clear indication for gemfibrozil or niacin, were likely to maintain triglycerides (TGs) < 500 mg/dL without these medications, and would not likely require close monitoring after discontinuation.19 The protocols allowed pharmacists to autonomously discontinue gemfibrozil or niacin if patients did not have a history of pancreatitis, TGs ≥ 400 mg/dL or a nonlipid indication for niacin (eg, pellagra) after establishing care at Truman VA. Additionally, both interacting medications had to be dispensed by the VA. When pharmacists discontinued a medication, it was documented in a note in the patient electronic health record. The prescriber was notified through the note and the patient received a notification letter. Follow-up laboratory monitoring was not required as part of the protocol.
If patients met any of the exclusion criteria for discontinuation, the primary care provider (PCP) was notified to place a consult to the PACT Pharmacy Clinic for individualized interventions and close monitoring. Patients prescribed niacin for nonlipid indications were allowed to continue with their current drug regimen. At each encounter, the PACT CPS assessed for ADRs, made individualized medication changes, and arranged follow-up appointments. Once the interaction was resolved and treatment goals met, the PCP resumed monitoring of the patient’s lipid therapy.
Following all pharmacist interventions, a retrospective quality improvement analysis was conducted. The primary outcome was to evaluate the impact of discontinuing gemfibrozil and niacin by protocol on patients’ laboratory results. The coprimary endpoints were to describe the change in TG levels and the percentage of patients with TGs ≥ 500 mg/dL at least 5 weeks following the pharmacist-directed discontinuation by protocol. Secondary outcomes included the time required to resolve the interactions and a description of the PACT CPS pharmacologic interventions. Additionally, a quality assurance peer review was used to ensure the pharmacists appropriately utilized the protocols.
Data were collected from August 2016 to September 2017 for patients prescribed gemfibrozil and from May 2017 to January 2018 for patients prescribed niacin. The time spent resolving interactions was quantified based on encounter data. Descriptive statistics were used to analyze demographic information and the endpoints associated with each outcome. The project was reviewed by the University of Missouri Institutional Review Board, Truman VA privacy and information security officers, and was determined to meet guidelines for quality improvement.
Results
The original STOP report included 397 drug interactions involving statins with gemfibrozil or niacin (Table 1). The majority of patients were white and male aged 60 to 79 years. Gemfibrozil was the most common drug involved in all interactions (79.8%). The most common statins were atorvastatin (40%) and simvastatin (36.5%).
Gemfibrozil-Statin Interactions
Pharmacists discontinued gemfibrozil by protocol for 94 patients (29.6%), and 107 patients (33.8%) were referred to the PACT Pharmacy Clinic (Figure 3). For the remaining 116 patients (36.6%), the drug interaction was addressed outside of the protocol for the following reasons: the drug interaction was resolved prior to pharmacist review; an interacting prescription was expired and not to be continued; the patient self-discontinued ≥ 1 interacting medications; the patient was deceased; the patient moved; the patient was receiving ≥ 1 interacting medications outside of the VA; or the prescriber resolved the interaction following notification by the pharmacist.
Ultimately, the interaction was resolved for all patients with a gemfibrozil-statin interaction on the STOP report. Following gemfibrozil discontinuation by protocol, 76 patients (80.9%) had TG laboratory results available and were included in the analysis. Sixty-two patients’ (82%) TG levels decreased or increased by < 100 mg/dL (Figure 4), and the TG levels of 1 patient (1.3%) increased above the threshold of 500 mg/dL. The mean (SD) time to the first laboratory result after the pharmacists mailed the notification letter was 6.5 (3.6) months (range, 1-17). The pharmacists spent a mean of 16 minutes per patient resolving each interaction.
Of the 107 patients referred to the PACT Pharmacy Clinic, 80 (74.8%) had TG laboratory results available and were included in the analysis. These patients were followed by the PACT CPS until the drug interaction was resolved and confirmed to have TG levels at goal (< 500 mg/dL). Gemfibrozil doses ranged from 300 mg daily to 600 mg twice daily, with 70% (n = 56) of patients taking 600 mg twice daily. The PACT CPS made 148 interventions (Table 2). Twenty-three (29%) patients required only gemfibrozil discontinuation. The remaining 57 patients (71%) required at least 2 medication interventions. The PACT CPS generated 213 encounters for resolving drug interactions with a median of 2 encounters per patient.
Quality assurance review identified 5 patients (5.3%) who underwent gemfibrozil discontinuation by protocol, despite having criteria that would have recommended against discontinuation. In accordance with the protocol criteria, these patients were later referred to the PACT Pharmacy Clinic. None of these patients experienced a TG increase at or above the threshold of 500 mg/dL after gemfibrozil was initially discontinued but were excluded from the earlier analysis.
Niacin-Statin Interactions
Pharmacists discontinued niacin by protocol for 48 patients (60.0%), and 22 patients (27.5%) were referred to the PACT Pharmacy Clinic (Figure 5). For the remaining 5 patients (6.3%), the interaction was either addressed outside the protocol prior to pharmacist review, or an interacting prescription was expired and not to be continued. Additionally, niacin was continued per prescriber preference in 5 patients (6.3%).
Thirty-six patients (75%) had TG laboratory results available following niacin discontinuation by protocol and were included in the analysis. Most patients’ (n = 33, 91.7%) TG levels decreased or increased by < 100 mg/dL. No patient had a TG level that increased higher than the threshold of 500 mg/dL. The mean (SD) time to the first laboratory result after the pharmacists mailed the notification letter, was 5.3 (2.5) months (range, 1.2-9.8). The pharmacists spent a mean of 15 minutes per patient resolving each interaction. The quality assurance review found no discrepancies in the pharmacists’ application of the protocol.
Of the 22 patients referred to the PACT Pharmacy Clinic, 16 (72.7%) patients had TG laboratory results available and were included in the analysis. As with the gemfibrozil interactions, these patients were followed by the PACT Pharmacy Clinic until the drug interaction was resolved and confirmed to have TGs at goal (< 500 mg/dL). Niacin doses ranged from 500 mg daily to 2,000 mg daily, with the majority of patients taking 1,000 mg daily. The PACT CPS made 23 interventions. The PACT CPS generated 46 encounters for resolving drug interactions with a median of 2 encounters per patient.
Discussion
Following gemfibrozil or niacin discontinuation by protocol, most patients with available laboratory results experienced either a decrease or modest TG elevation. The proportion of patients experiencing a decrease in TGs was unexpected but potentially multifactorial. Individual causes for the decrease in TGs were beyond the scope of this analysis. The retrospective design limited the ability to identify variables that could have impacted TG levels when gemfibrozil or niacin were started and discontinued. Although the treatment of TG levels is not indicated until it is ≥ 500 mg/dL, due to an increased risk of pancreatitis, both protocols excluded patients with a history of TGs ≥ 400 mg/dL.19 The lower threshold was set to compensate for anticipated increase in TG levels, following gemfibrozil or niacin discontinuation, and to minimize the number of patients with TG levels ≥ 500 mg/dL. The actual impact on patients’ TG levels supports the use of this lower threshold in the protocol.
When TG levels increased by 200 to 249 mg/dL after gemfibrozil or niacin discontinuation, patients were evaluated for possible underlying causes, which occurred for 4 gemfibrozil and 1 niacin patient. One patient started a β-blocker after gemfibrozil was initiated, and 3 patients were taking gemfibrozil prior to establishing care at the VA. The TG levels of the patient taking niacin correlated with an increased hemoglobin A1c. The TG level for only 1 patient taking gemfibrozil increased above the 500 mg/dL threshold. The patient had several comorbidities known to increase TG levels, but the comorbidities were previously well controlled. No additional medication changes were made at that time, and the TG levels on the next fasting lipid panel decreased to goal. The patient did not experience any negative clinical sequelae from the elevated TG levels.
Thirty-five patients (36%) who were referred to the PACT Pharmacy Clinic required only either gemfibrozil or niacin discontinuation. These patients were evaluated to identify whether adjustments to the protocols would have allowed for pharmacist discontinuation without referral to the PACT Pharmacy Clinic. Twenty-four of these patients (69%) had repeated TG levels ≥ 400 mg/dL prior to referral to the PACT Pharmacy Clinic. Additionally, there was no correlation between the gemfibrozil or niacin doses and the change in TG levels following discontinuation. These data indicate the protocols appropriately identified patients who did not have an indication for gemfibrozil or niacin.
In addition to drug interactions identified on the STOP report, the PACT CPS resolved 12 additional interactions involving simvastatin and gemfibrozil. Additionally, unnecessary lipid medications were deprescribed. The PACT CPS identified 13 patients who experienced myalgias, an ADR attributed to the gemfibrozil- statin interaction. Of those, 9 patients’ ADRs resolved after discontinuing gemfibrozil alone. For the remaining 4 patients, additional interventions to convert the patient to another statin were required to resolve the ADR.
Using pharmacists to address the drug interactions shifted workload from the prescribers and other primary care team members. The mean time spent to resolve both gemfibrozil and niacin interactions by protocol was 15.5 minutes. One hundred fortytwo patients (35.8%) had drug interactions resolved by protocol, saving the PACT CPS’ expertise for patients requiring individualized interventions. Drug interactions were resolved within 4 PACT CPS encounters for 93.8% of the patients taking gemfibrozil and within 3 PACT CPS encounters for 93.8% of the patients taking niacin.
The protocols allowed 12 additional pharmacists who did not have an ambulatory care scope of practice to assist the PACT CPS in mitigating the STOP drug interactions. These pharmacists otherwise would have been limited to making consultative recommendations. Simultaneously, the design allowed for the PACT pharmacists’ expertise to be allocated for patients most likely to require interventions beyond the protocols. This type of intraprofessional referral process is not well described in the medical literature. To the authors’ knowledge, the only studies described referrals from hospital pharmacists to community pharmacists during transitions of care on hospital discharge.20,21
Limitations
The results of this study are derived from a retrospective chart review at a single VA facility. The autonomous nature of PACT CPS interventions may be difficult to replicate in other settings that do not permit pharmacists the same prescriptive authority. This analysis was designed to demonstrate the impact of the pharmacist in resolving major drug interactions. Patients referred to the PACT Pharmacy Clinic who also had their lipid medications adjusted by a nonpharmacist provider were excluded. However, this may have minimized the impact of the PACT CPS on the patient care provided. As postintervention laboratory results were not available for all patients, some patients’ TG levels could have increased above the 500 mg/dL threshold but were not identified. The time investment was extensive and likely underestimates the true cost of implementing the interventions.
Because notification letters were used to instruct patients to stop gemfibrozil or niacin, several considerations need to be addressed when interpreting the follow-up laboratory results. First, we cannot confirm whether the patients received the letter or the exact date the letter was received. Additionally, we cannot confirm whether the patients followed the instructions to stop the interacting medications or the date the medications were stopped. It is possible some patients were still taking the interacting medication when the first laboratory was drawn. Should a patient have continued the interacting medication, most would have run out and been unable to obtain a refill within 90 days of receiving the letter, as this is the maximum amount dispensed at one time. The mean time to the first laboratory result for both gemfibrozil and niacin was 6.5 and 5.3 months, respectively. Approximately 85% of patients completed the first laboratory test at least 3 months after the letter was mailed.
The protocols were designed to assess whether gemfibrozil or niacin was indicated and did not assess whether the statin was indicated. Therefore, discontinuing the statin also could have resolved the interaction appropriately. However, due to characteristics of the patient population and recommendations in current lipid guidelines, it was more likely the statin would be indicated.22,23 The protocols also assumed that patients eligible for gemfibrozil or niacin discontinuation would not need additional changes to their lipid medications. The medication changes made by the PACT CPS may have gone beyond those minimally necessary to resolve the drug interaction and maintain TG goals. Patients who had gemfibrozil or niacin discontinued by protocol also may have benefited from additional optimization of their lipid medications.
Conclusions
This quality improvement analysis supports further evaluation of the complementary use of protocols and PACT CPS prescriptive authority to resolve statin drug interactions. The gemfibrozil and niacin protocols appropriately identified patients who were less likely to experience an adverse change in TG laboratory results. Patients more likely to require additional medication interventions were appropriately referred to the PACT Pharmacy Clinics for individualized care. These data support expanded roles for pharmacists, across various settings, to mitigate select drug interactions at the Truman VA.

Catheter ablation of AFib improves quality of life more than medications do
Background: Catheter ablation of AFib (primarily pulmonary vein isolation) has been shown to result in better maintenance of sinus rhythm than medications. Small studies of QOL have shown mixed results. Larger trials were needed.
Study design: Open-label randomized multisite clinical trial of catheter ablation (pulmonary vein isolation with additional ablation procedure at the treating physician discretion) versus standard rate and/or rhythm control medications (chosen by clinician discretion). Patients were included for paroxysmal or persistent AFib and either age 65 years or older or age younger than 65 years with one additional stroke risk factor. Quality of life surveys – the Atrial Fibrillation Effect on Quality of Life (AFEQT) questionnaire and the Mayo AF-Specific Symptom Inventory (MAFSI) – were completed at baseline, and at 3, 12, 24, 36, 48, and 60 months.
Setting: 126 centers in 10 countries.
Synopsis: The study included 2,204 patients with median age of 68 years, diagnosed with AFib a median of 1.1 years prior, who were followed for a median of 48 months. The median CHA2DS2-VASc score was 3.0.
Self-reported AFib dropped from 86.0% to 21.1% in the ablation group and from 83.7% to 39.8% in the medication group at 12 months. The AFEQT score (range 0-100, higher score indicating better QOL) increased from 62.9 to 86.4 in the ablation group and increased from 63.1 to 80.9 in the medication group (for a mean difference of 5.3 points [95% confidence interval, 3.7-6.9; P less than .001] favoring ablation). MAFSI symptom frequency score and symptom severity score also showed improvement in symptoms favoring ablation. Post hoc subgroup analysis showed that those with the most severe symptoms had the largest benefit from ablation.
The primary limitation is the lack of patient blinding (may bias self-reported symptoms).
While the CABANA trial efficacy study (published separately) showed that catheter ablation results in no significant difference in the combined outcome of death, disabling stroke, serious bleeding, or cardiac arrest, the CABANA QOL study, reviewed here, shows that ablation does result in improved QOL and reduced symptoms, compared with medical therapy.
Bottom line: Catheter ablation of AFib can be done safely and successfully at experienced centers. In patients with AFib-related symptoms, ablation reduces symptoms and improves QOL somewhat more than medications do. The most severely symptomatic patients appear to obtain the most benefit.

High ‘forever chemicals’ in blood linked to earlier menopause
In a national sample of U.S. women in their mid-40s to mid-50s, those with high serum levels of per- and polyfluoroalkyl substances (PFAS) were likely to enter menopause 2 years earlier than those with low levels of these chemicals.
That is, the median age of natural menopause was 52.8 years versus 50.8 years in women with high versus low serum levels of these chemicals in an analysis of data from more than 1,100 women in the Study of Women’s Health Across the Nation (SWAN) Multi-Pollutant Study, which excluded women with premature menopause (before age 40) or early menopause (before age 45).
“This study suggests that select PFAS serum concentrations are associated with earlier natural menopause, a risk factor for adverse health outcomes in later life,” Ning Ding, PhD, MPH, University of Michigan, Ann Arbor, and colleagues concluded in their article, published online June 3 in the Journal of Clinical Endocrinology & Metabolism.
“Even menopause a few years earlier than usual could have a significant impact on cardiovascular and bone health, quality of life, and overall health in general among women,” senior author Sung Kyun Park, ScD, MPH, from the same institution, added in a statement.
PFAS don’t break down in the body, build up with time
PFAS have been widely used in many consumer and industrial products such as nonstick cookware, stain-repellent carpets, waterproof rain gear, microwave popcorn bags, and firefighting foam, the authors explained.
These have been dubbed “forever chemicals” because they do not degrade. Household water for an estimated 110 million Americans (one in three) may be contaminated with these chemicals, according to an Endocrine Society press release.
“PFAS are everywhere. Once they enter the body, they don’t break down and [they] build up over time,” said Dr. Ding. “Because of their persistence in humans and potentially detrimental effects on ovarian function, it is important to raise awareness of this issue and reduce exposure to these chemicals.”
Environmental exposure and accelerated ovarian aging
Earlier menopause has been associated with an increased risk of cardiovascular disease, osteoporosis, and earlier cardiovascular and overall mortality, and environmental exposure may accelerate ovarian aging, the authors wrote.
PFAS, especially the most studied types – perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) – are plausible endocrine-disrupting chemicals, but findings so far have been inconsistent.
A study of people in Ohio exposed to contaminated water found that women with earlier natural menopause had higher serum PFOA and PFOS levels (J Clin Endocriniol Metab. 2011;96:1747-53).
But in research based on National Health and Nutrition Survey Examination data, higher PFOA, PFOS, or perfluorononanoic acid (PFNA) levels were not linked to earlier menopause, although higher levels of perfluorohexane sulfonic acid (PFHxS) were (Environ Health Perspect. 2014;122:145-50).
There may have been reverse causation, where postmenopausal women had higher PFAS levels because they were not excreting these chemicals in menstrual blood.
In a third study, PFOA exposure was not linked with age at menopause onset, but this was based on recall from 10 years earlier (Environ Res. 2016;146:323-30).
The current analysis examined data from 1,120 premenopausal women who were aged 45-56 years from 1999 to 2000.
The women were seen at five sites (Boston; Detroit; Los Angeles; Oakland, Calif.; and Pittsburgh) and were ethnically diverse (577 white, 235 black, 142 Chinese, and 166 Japanese).
Baseline serum PFAS levels were measured using high performance liquid chromatography-mass spectrometry. The women were followed up to 2017 and incident menopause (12 consecutive months with no menstruation) was determined from annual interviews.
Of the 1,120 women and 5,466 person-years of follow-up, 578 women had a known date of natural incident menopause and were included in the analysis. The remaining 542 women were excluded mainly because their date of final menstruation was unknown because of hormone therapy (451) or they had a hysterectomy, or did not enter menopause during the study.
Compared with women in the lowest tertile of PFOS levels, women in the highest tertile had a significant 26%-27% greater risk of incident menopause – after adjusting for age, body mass index, and prior hormone use, race/ethnicity, study site, education, physical activity, smoking status, and parity.
Higher PFOA and PFNA levels but not higher PFHxS levels were also associated with increased risk.
Compared with women with a low overall PFAS level, those with a high level had a 63% increased risk of incident menopause (hazard ratio, 1.63; 95% confidence interval, 1.08-2.45), equivalent to having menopause a median of 2 years earlier.
Although production and use of some types of PFAS in the United States are declining, Dr. Ding and colleagues wrote, exposure continues, along with associated potential hazards to human reproductive health.
“Due to PFAS widespread use and environmental persistence, their potential adverse effects remain a public health concern,” they concluded.

Erectile dysfunction: How to help patients & partners
THE CASE
Eric M,* a 36-year-old new patient, visits a primary care clinic for a check-up accompanied by his wife. A thorough history and physical exam reveal no concerns. He is active and a nonsmoker, drinks only socially, takes no medications, and reports no concerning symptoms. At the end of the visit, though, he says he has been experiencing erectile dysfunction for the past 6 months. What began as intermittent difficulty maintaining erections now “happens a lot.” He is distressed and says, “It just came out of the blue.” The patient’s wife then says she believes men cannot achieve erections if they are having an affair. When the chagrined patient simply asks for “those pills,” his wife says in a raised voice, “He’s a liar!”
●
*The patient’s name has been changed to protect his identity.
Some family physicians may feel ill-equipped to talk about sexual and relational problems and lack the skills to effectively counsel on these matters.1 Despite the fact that more than 70% of adult patients want to discuss sexual topics with their family physician, sexual problems are documented in as few as 2% of patient notes.2 One of the most commonly noted sexual health concerns is erectile dysfunction (ED), estimated to occur in 35% of men ages 40 to 70.3 Many ED cases have psychological antecedents including stress, depression, performance anxiety, pornography addiction, and relationship concerns.4,5
Assessing ED. The inability to achieve or maintain an erection needed for satisfactory sexual activity is typically diagnosed through symptom self-report and with thorough history taking and physical examination.6 However, more objective scales can be used. In particular, the International Index of Erectile Function, a 15-question scale, is useful for both diagnosis and treatment monitoring (www.baus.org.uk/_userfiles/pages/files/Patients/Leaflets/iief.pdf).7 Common contributors to ED can be vascular (eg, hypertension), neurologic (eg, multiple sclerosis), psychological (noted earlier), or hormonal (eg, thyroid imbalances).6 In this article, we focus on the relationship context in which ED exists. A review of medical evaluation and management can be found elsewhere.8
Key relational questions
Identify norms that are specific to the couple. Patients from a variety of cultures prefer that their clinicians initiate the conversation about ED.11,12 We specifically recommend that clinicians, using relationally focused questions, inquire about sexual norms and desires that may be situated in culture, family of origin, or gender (TABLE 1).
Continue to: Treating ED within a relationship
Treating ED within a relationship
Once a couple’s sexual relationship has been fully assessed, you may confidently develop a treatment plan for managing sexual dysfunction relationally as well as medically, an approach to ED advised by the American Urological Association.13 We propose that primary care treatment for ED involve collaboration between the physician, the patient/couple (if the patient is partnered), and, as needed, a behavioral health specialist.
The physician’s role ...
Managing ED relationally is important on many fronts. If, for instance, a type-5 phosphodiesterase (PDE-5) inhibitor is needed, both the patient and partner should learn about best practices for optimizing success, such as avoiding excessive alcohol intake or high-fat meals immediately before and after taking a PDE-5.14
Sex ed. Regardless of the couple’s age, be prepared to offer high-quality sexual education. Either partner may have faulty knowledge (or even a lack of knowledge) of basic sexual functioning. Physicians have an opportunity to explain healthy erectile functioning, the sexual response cycle, and ways in which PDE-5 medications work (and do not work). (For a list of resources to facilitate these discussions, see TABLE 2.)
Avoid avoidance. Physicians can intervene on patterns of shame that may surround ED simply by discussing sexual functioning openly and honestly. ED often persists due to avoidance—ie, anxiety about sexual performance can lead couples to avoid sex, which perpetuates more anxiety and avoidance. Normalizing typical sexual functioning, encouraging couples to “avoid avoidance,” and providing referrals as needed are core elements of relational intervention for ED.
Setting the tone. Family physicians are not routinely trained in couples therapy. However, you can employ communication skills that allow each partner to be heard by using empathic/reflective listening, de-escalation, and reframing. Asking “What effect are the sexual concerns having on both of you?” and “What were the circumstances of the last sexual encounter that were pleasing to both of you?” can help promote intimacy and mutual satisfaction.
Continue to: The behavioral specialist's role
The behavioral specialist’s role
Behavioral health specialists may treat ED using methods such as cognitive behavioral therapy or evidence-based couple interventions.4 Cognitive methods for the treatment of ED include examination of maladaptive thoughts around pressure to perform and achieving sexual pleasure. Behavioral methods for treatment of ED are typically aimed at the de-coupling of anxiety and sexual activity. These treatments can include relaxation and desensitization, specifically sensate focus therapy.15
Sensate focus therapy involves a specific set of prescriptive rules for sexual activity, initially restricting touch to non-demand pleasurable touch (eg, holding hands) that allows couples to connect in a low-anxiety context focused on relaxation and connection. As couples are able to control anxiety while engaging in these activities, they engage in increasingly more intimate activities. Additionally, behavioral health specialists trained in couples therapy are vital to helping increase communication regarding sexual activity, sexual scripts, and the relationship in general.4
Identifying a treatment team
In coordinating couples care in the treatment of ED, enlist the help of a therapist who has specific knowledge and skills in the treatment of sexual disorders. While the number of qualified or certified sex therapists is limited, referring providers can visit the American Association of Sexuality Educators, Counselors, and Therapists Web site (www.aasect.org) for possible referral sources. Another option is the American Association for Marriage and Family Therapy Web site (www.aamft.org) under “Find a therapist.” Lastly, the Society for Sex Therapy and Research (www.sstarnet.org) is another professional association that provides information and local referral sources. For patients and partners located in rural areas where access is limited, telehealth options may need to be explored.
THE CASE
Mr. M and his wife were seen for a follow-up appointment by his primary care provider, who ruled out any additional causes of ED (eg, hormonal, vascular), discussed with both the patient and his wife basic sexual health and sexual functioning, dispelled several commonly held myths (ie, individuals cannot obtain an erection because of infidelity or lying), validated sexual concerns as a significant health issue, and prescribed a PDE-5 inhibitor.
Mr. M and his wife were referred to a behavioral health specialist in the clinic who had expertise in couples therapy. At several subsequent visits, the patient and his wife worked on improving the quality and quantity of communication regarding their sexual goals, mutual de-escalation of anxiety, increased emotional intimacy, and sensate focus techniques.
Continue to: As the result of the interventions...
As the result of these interventions, both the patient and his wife were able to engage in sex with less anxiety, and the patient increasingly was able to achieve more satisfactory erections without the use of the PDE-5 inhibitor. At the conclusion of therapy, the patient and his wife reported an increase in sexual satisfaction.

THE CASE
Eric M,* a 36-year-old new patient, visits a primary care clinic for a check-up accompanied by his wife. A thorough history and physical exam reveal no concerns. He is active and a nonsmoker, drinks only socially, takes no medications, and reports no concerning symptoms. At the end of the visit, though, he says he has been experiencing erectile dysfunction for the past 6 months. What began as intermittent difficulty maintaining erections now “happens a lot.” He is distressed and says, “It just came out of the blue.” The patient’s wife then says she believes men cannot achieve erections if they are having an affair. When the chagrined patient simply asks for “those pills,” his wife says in a raised voice, “He’s a liar!”

Some family physicians may feel ill-equipped to talk about sexual and relational problems and lack the skills to effectively counsel on these matters.1 Despite the fact that more than 70% of adult patients want to discuss sexual topics with their family physician, sexual problems are documented in as few as 2% of patient notes.2 One of the most commonly noted sexual health concerns is erectile dysfunction (ED), estimated to occur in 35% of men ages 40 to 70.3 Many ED cases have psychological antecedents including stress, depression, performance anxiety, pornography addiction, and relationship concerns.4,5
Assessing ED. The inability to achieve or maintain an erection needed for satisfactory sexual activity is typically diagnosed through symptom self-report and with thorough history taking and physical examination.6 However, more objective scales can be used. In particular, the International Index of Erectile Function, a 15-question scale, is useful for both diagnosis and treatment monitoring (www.baus.org.uk/_userfiles/pages/files/Patients/Leaflets/iief.pdf).7 Common contributors to ED can be vascular (eg, hypertension), neurologic (eg, multiple sclerosis), psychological (noted earlier), or hormonal (eg, thyroid imbalances).6 In this article, we focus on the relationship context in which ED exists. A review of medical evaluation and management can be found elsewhere.8
Key relational questions
Identify norms that are specific to the couple. Patients from a variety of cultures prefer that their clinicians initiate the conversation about ED.11,12 We specifically recommend that clinicians, using relationally focused questions, inquire about sexual norms and desires that may be situated in culture, family of origin, or gender (TABLE 1).

Treating ED within a relationship
Once a couple’s sexual relationship has been fully assessed, you may confidently develop a treatment plan for managing sexual dysfunction relationally as well as medically, an approach to ED advised by the American Urological Association.13 We propose that primary care treatment for ED involve collaboration between the physician, the patient/couple (if the patient is partnered), and, as needed, a behavioral health specialist.
The physician’s role ...
Managing ED relationally is important on many fronts. If, for instance, a type-5 phosphodiesterase (PDE-5) inhibitor is needed, both the patient and partner should learn about best practices for optimizing success, such as avoiding excessive alcohol intake or high-fat meals immediately before and after taking a PDE-5.14
Sex ed. Regardless of the couple’s age, be prepared to offer high-quality sexual education. Either partner may have faulty knowledge (or even a lack of knowledge) of basic sexual functioning. Physicians have an opportunity to explain healthy erectile functioning, the sexual response cycle, and ways in which PDE-5 medications work (and do not work). (For a list of resources to facilitate these discussions, see TABLE 2.)
Avoid avoidance. Physicians can intervene on patterns of shame that may surround ED simply by discussing sexual functioning openly and honestly. ED often persists due to avoidance—ie, anxiety about sexual performance can lead couples to avoid sex, which perpetuates more anxiety and avoidance. Normalizing typical sexual functioning, encouraging couples to “avoid avoidance,” and providing referrals as needed are core elements of relational intervention for ED.
Setting the tone. Family physicians are not routinely trained in couples therapy. However, you can employ communication skills that allow each partner to be heard by using empathic/reflective listening, de-escalation, and reframing. Asking “What effect are the sexual concerns having on both of you?” and “What were the circumstances of the last sexual encounter that were pleasing to both of you?” can help promote intimacy and mutual satisfaction.
Continue to: The behavioral specialist's role
The behavioral specialist’s role
Behavioral health specialists may treat ED using methods such as cognitive behavioral therapy or evidence-based couple interventions.4 Cognitive methods for the treatment of ED include examination of maladaptive thoughts around pressure to perform and achieving sexual pleasure. Behavioral methods for treatment of ED are typically aimed at the de-coupling of anxiety and sexual activity. These treatments can include relaxation and desensitization, specifically sensate focus therapy.15
Sensate focus therapy involves a specific set of prescriptive rules for sexual activity, initially restricting touch to non-demand pleasurable touch (eg, holding hands) that allows couples to connect in a low-anxiety context focused on relaxation and connection. As couples are able to control anxiety while engaging in these activities, they engage in increasingly more intimate activities. Additionally, behavioral health specialists trained in couples therapy are vital to helping increase communication regarding sexual activity, sexual scripts, and the relationship in general.4
Identifying a treatment team
In coordinating couples care in the treatment of ED, enlist the help of a therapist who has specific knowledge and skills in the treatment of sexual disorders. While the number of qualified or certified sex therapists is limited, referring providers can visit the American Association of Sexuality Educators, Counselors, and Therapists Web site (www.aasect.org) for possible referral sources. Another option is the American Association for Marriage and Family Therapy Web site (www.aamft.org) under “Find a therapist.” Lastly, the Society for Sex Therapy and Research (www.sstarnet.org) is another professional association that provides information and local referral sources. For patients and partners located in rural areas where access is limited, telehealth options may need to be explored.
THE CASE
Mr. M and his wife were seen for a follow-up appointment by his primary care provider, who ruled out any additional causes of ED (eg, hormonal, vascular), discussed with both the patient and his wife basic sexual health and sexual functioning, dispelled several commonly held myths (ie, individuals cannot obtain an erection because of infidelity or lying), validated sexual concerns as a significant health issue, and prescribed a PDE-5 inhibitor.
Mr. M and his wife were referred to a behavioral health specialist in the clinic who had expertise in couples therapy. At several subsequent visits, the patient and his wife worked on improving the quality and quantity of communication regarding their sexual goals, mutual de-escalation of anxiety, increased emotional intimacy, and sensate focus techniques.
Continue to: As the result of the interventions...
As the result of these interventions, both the patient and his wife were able to engage in sex with less anxiety, and the patient increasingly was able to achieve more satisfactory erections without the use of the PDE-5 inhibitor. At the conclusion of therapy, the patient and his wife reported an increase in sexual satisfaction.

Biologics may carry melanoma risk for patients with immune-mediated inflammatory diseases
The in a systematic review and meta-analysis published in JAMA Dermatology.
The studies included in the analysis, however, had limitations, including a lack of those comparing biologic and conventional systemic therapy in psoriasis and inflammatory bowel disease (IBD), according to Shamarke Esse, MRes, of the division of musculoskeletal and dermatological sciences at the University of Manchester (England) and colleagues. “We advocate for more large, well-designed studies of this issue to be performed to help improve certainty” regarding this association, they wrote.
Previous studies that have found an increased risk of melanoma in patients on biologics for psoriasis, rheumatoid arthritis, and IBD have “typically used the general population as the comparator,” they noted. There is a large amount of evidence that has established short-term efficacy and safety of biologics, compared with conventional systemic treatments, but concerns about longer-term cancer risk associated with biologics remains a concern. Moreover, they added, “melanoma is a highly immunogenic skin cancer and therefore of concern to patients treated with TNFIs [tumor necrosis factor inhibitors] because melanoma risk increases with suppression of the immune system and TNF-alpha plays an important role in the immune surveillance of tumors.12,13
In their review, the researchers identified seven cohort studies from MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) databases published between January 1995 and February 2019 that evaluated melanoma risk in about 34,000 patients receiving biologics and 135,370 patients who had never been treated with biologics, and were receiving conventional systemic therapy for psoriasis, RA, or IBD. Of these, four studies were in patients with RA, two studies were in patients with IBD, and a single study was in patients with psoriasis. Six studies examined patients taking TNF inhibitors, but only one of six studies had information on specific TNF inhibitors (adalimumab, etanercept, and infliximab) in patients with RA. One study evaluated abatacept and rituximab in RA patients.
The researchers analyzed the pooled relative risk across all studies. Compared with patients who received conventional systemic therapy, there was a nonsignificant association with risk of melanoma in patients with psoriasis (hazard ratio, 1.57; 95% confidence interval, 0.61-4.09), RA (pooled relative risk, 1.20; 95% CI, 0.83-1.74), and IBD (pRR, 1.20; 95% CI, 0.60-2.40).
Among RA patients who received TNF inhibitors only, there was a slightly elevated nonsignificant risk of melanoma (pRR, 1.08; 95% CI, 0.81-1.43). Patients receiving rituximab had a pRR of 0.73 (95% CI, 0.38-1.39), and patients taking abatacept had a pRR of 1.43 (95% CI, 0.66-3.09), compared with RA patients receiving conventional systemic therapy. When excluding two major studies in the RA subgroup of patients in a sensitivity analysis, pooled risk estimates varied from 0.91 (95% CI, 0.69-1.18) to 1.95 (95% CI, 1.16- 3.30). There were no significant between-study heterogeneity or publication bias among the IBD and RA studies.
Mr. Esse and colleagues acknowledged the small number of IBD and psoriasis studies in the meta-analysis, which could affect pooled risk estimates. “Any future update of our study through the inclusion of newly published studies may produce significantly different pooled risk estimates than those reported in our meta-analysis,” they said. In addition, the use of health insurance databases, lack of risk factors for melanoma, and inconsistent information about treatment duration for patients receiving conventional systemic therapy were also limitations.
“Prospective cohort studies using an active comparator, new-user study design providing detailed information on treatment history, concomitant treatments, biologic and conventional systemic treatment duration, recreational and treatment-related UV exposure, skin color, and date of melanoma diagnosis are required to help improve certainty. These studies would also need to account for key risk factors and the latency period of melanoma,” the researchers said.
Mr. Esse disclosed being funded by a PhD studentship from the Psoriasis Association. One author disclosed receiving personal fees from Janssen, LEO Pharma, Lilly, and Novartis outside the study; another disclosed receiving grants and personal fees from those and several other pharmaceutical companies during the study, and personal fees from several pharmaceutical companies outside of the submitted work; the fourth author had no disclosures.

Among RA patients who received TNF inhibitors only, there was a slightly elevated nonsignificant risk of melanoma (pRR, 1.08; 95% CI, 0.81-1.43). Patients receiving rituximab had a pRR of 0.73 (95% CI, 0.38-1.39), and patients taking abatacept had a pRR of 1.43 (95% CI, 0.66-3.09), compared with RA patients receiving conventional systemic therapy. When excluding two major studies in the RA subgroup of patients in a sensitivity analysis, pooled risk estimates varied from 0.91 (95% CI, 0.69-1.18) to 1.95 (95% CI, 1.16- 3.30). There were no significant between-study heterogeneity or publication bias among the IBD and RA studies.
Mr. Esse and colleagues acknowledged the small number of IBD and psoriasis studies in the meta-analysis, which could affect pooled risk estimates. “Any future update of our study through the inclusion of newly published studies may produce significantly different pooled risk estimates than those reported in our meta-analysis,” they said. In addition, the use of health insurance databases, lack of risk factors for melanoma, and inconsistent information about treatment duration for patients receiving conventional systemic therapy were also limitations.
“Prospective cohort studies using an active comparator, new-user study design providing detailed information on treatment history, concomitant treatments, biologic and conventional systemic treatment duration, recreational and treatment-related UV exposure, skin color, and date of melanoma diagnosis are required to help improve certainty. These studies would also need to account for key risk factors and the latency period of melanoma,” the researchers said.
Mr. Esse disclosed being funded by a PhD studentship from the Psoriasis Association. One author disclosed receiving personal fees from Janssen, LEO Pharma, Lilly, and Novartis outside the study; another disclosed receiving grants and personal fees from those and several other pharmaceutical companies during the study, and personal fees from several pharmaceutical companies outside of the submitted work; the fourth author had no disclosures.

Acute rhinosinusitis: When to prescribe an antibiotic
An estimated 30 million cases of acute rhinosinusitis (ARS) occur every year in the United States.1 More than 80% of people with ARS are prescribed antibiotics in North America, accounting for 15% to 20% of all antibiotic prescriptions in the adult outpatient setting.2,3 Many of these prescriptions are unnecessary, as the most common cause of ARS is a virus.4,5 Evidence consistently shows that symptoms of ARS will resolve spontaneously in most patients and that only those patients with severe or prolonged symptoms require consideration of antibiotic therapy.1,2,4,6 Nearly half of all patients will improve within 1 week and two-thirds of patients will improve within 2 weeks without the use of antibiotics.7 In children, only about 6% to 7% presenting with upper respiratory symptoms meet the criteria for acute bacterial rhinosinusitis (ABRS),8 which we’ll detail in a bit. For most patients, treatment should consist of symptom management.5
But what about the minority who require antibiotic therapy? This article reviews how to evaluate patients with ARS, identify those who require antibiotics, and prescribe the most appropriate antibiotic treatment regimens.
Diagnosis: Distinguishing viral from bacterial disease
ARS is defined as the sudden onset of purulent nasal discharge plus either nasal blockage or facial pressure/pain lasting < 4 weeks.3,9 Additional signs and symptoms may include postnasal drip, a reduced sense of smell, sinus tenderness to palpation, and maxillary toothaches.10,11
ARS may be viral or bacterial in etiology, with the most common bacterial organisms being Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.1,3,5 The most common viral causes are influenza, parainfluenza, and rhinovirus. Approximately 90% to 98% of cases of ARS are viral6,11; only about 0.5% to 2% of viral rhinosinusitis episodes are complicated by bacterial infection.1,10-12
Diagnose ABRS when symptoms of ARS fail to improve after 10 days or symptoms of ARS worsen within 10 days after initial improvement (“double sickening”).1,11 Symptoms that are significantly associated with ABRS are unilateral sinus pain and reported maxillary pain. The presence of facial or dental pain correlates with ABRS but does not identify the specific sinus involved.1
There isn’t good correlation between patients saying they have sinusitis and actually having it.13 A 2019 meta-analysis by Ebell et al14 reported that based on limited data, the overall clinical impression, fetid odor on the breath, and pain in the teeth are the best individual clinical predictors of ABRS.
As recommended by the Infectious Disease Society of America (IDSA), a diagnosis of ABRS is also reasonable in patients who present with severe symptoms at the onset.6 Although there is no consensus about what constitutes “severe symptoms,” they are often described as a temperature ≥ 102°F (39°C) plus 3 to 4 days of purulent nasal drainage.1,4,6
Continue to: Additional symptoms of ABRS may include...
Additional symptoms of ABRS may include cough, fatigue, decreased or lack of sense of smell (hyposmia or anosmia), and ear pressure.10 Another sign of “double sickening” is the development of a fever after several days of symptoms.1,9,15 Viral sinusitis typically lasts 5 to 7 days with a peak at days 2 to 3.1,15 If symptoms continue for 10 days, there is a 60% chance of bacterial sinusitis, although some viral rhinosinusitis symptoms persist for > 14 days.1,5 Beyond 4 to 12 weeks, sinusitis is classified as subacute or chronic.3
Physical exam findings and the limited roles of imaging and labs
Common physical exam findings associated with the diagnosis of ABRS include altered speech indicating nasal obstruction; edema or erythema of the skin indicating congested capillaries; tenderness to palpation over the cheeks or upper teeth; odorous breath; and purulent drainage from the nose or in the posterior pharynx.
In a study by Hansen et al13 (N = 174), the only sign that showed significant association with ABRS (diagnosed by sinus aspiration or lavage) was unilateral tenderness of the maxillary sinuses. The presence of purulent drainage in the nose or posterior pharynx also has significant diagnostic value, as it predicts the presence of bacteria on antral aspiration.1 Purulent discharge in the pharynx is associated with a higher likelihood of benefit from antibiotic therapy compared to placebo (number needed to treat [NNT] = 8).16 However, colored nasal discharge indicates the presence of neutrophils—not bacteria—and does not predict the likelihood of bacterial sinus infection.14,17 Therefore, the history and physical exam should focus on location of pain (sinus and/or teeth), duration of symptoms, presence of fever, change in symptom severity, attempted home therapies, sinus tenderness on exam, breath odor, and purulent drainage seen in the nasal cavity or posterior pharynx.13,14
Radiographic imaging has no role in the diagnosis or treatment of uncomplicated ABRS because viral and bacterial etiologies have similar radiographic appearances. Additionally, employing radiologic imaging would increase health care costs by at least 4-fold.5,6,8,17 The American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) clinical practice guidelines recommend against radiographic imaging for patients who meet the diagnostic criteria for ABRS unless concern exists for a complication or an alternate diagnosis is suspected.1 Computed tomography (CT) imaging of the sinuses may be warranted in patients with severe headaches, facial swelling, cranial nerve palsies, or bulging of the eye (proptosis), all of which indicate a potential complication of ABRS.1
Laboratory evaluations. ABRS is a clinical diagnosis; therefore, routine lab work, such as a white blood cell count, C-reactive protein (CRP) level, and/or erythrocyte sedimentation rate (ESR), are not indicated unless an alternate diagnosis is suspected.1,5,13,18,19
Continue to: In one study...
In one study, CRP > 10 mg/L and ESR > 10 mm/h were the strongest individual predictors of purulent antral puncture aspirate or positive bacterial culture of aspirate, which is considered diagnostic for ABRS. 20 However, CRP and ESR by themselves are not adequate to diagnose ABRS.20 This study developed a clinical decision rule that used symptoms, signs, and laboratory values to rate the likelihood of ABRS as being either low, moderate, or high. However, this clinical decision rule has not been prospectively validated.
Thus, CRP and ESR elevations can support the diagnosis of ABRS, but the low sensitivity of these tests precludes their use as a screening tool for ABRS.14,18 Studies by Ebell19 and Huang21 have shown some benefit to dipstick assay of nasal secretions for the diagnosis of ABRS, but this method is not validated or widely used.19,21
Treatment: From managing symptoms to prescribing antibiotics
Overprescribing antibiotics for ARS is a prominent health care issue. In fact, 5 of 9 placebo-controlled studies showed that most people improve within 2 weeks regardless of antibiotic use (N = 1058).3 Therefore, weigh the decision to treat ABRS with antibiotics against the risk for potential adverse reactions and within the context of antibiotic stewardship.2,9,12,22-24 Consider antibiotics only if patients meet the diagnostic criteria for ABRS (TABLE 11,6) or, occasionally, for patients with severe symptoms upon presentation, such as a temperature ≥ 102°F (39°C) plus purulent nasal discharge for 3 to 4 days.1 The most commonly reported adverse effects of antibiotics are gastrointestinal in nature and include nausea, vomiting, and diarrhea.2,9
Symptomatic management for both ARS and ABRS is recommended as first-line therapy; it should be offered to patients before making a diagnosis of ABRS.1,5,9,25 Consider using analgesics, topical intranasal steroids, and/or nasal saline irrigation to alleviate symptoms and improve quality of life.1,5,25 Interventions with questionable or unproven efficacy include the use of antihistamines, systemic steroids, decongestants, and mucolytics, but they may be considered on an individual basis.1 A systematic review found that topical nasal steroids relieved facial pain and nasal congestion in patients with rhinitis and acute sinusitis (NNT = 14).1,26
Even after diagnosing ABRS, clinicians should offer watchful waiting and symptomatic therapies as long as patients have adequate access to follow-up (TABLE 2,1,15FIGURE1,6). Antibiotic therapy can then be initiated if symptoms do not improve after an additional 7 days of watchful waiting or if symptoms worsen at any time. It is reasonable to give patients a prescription to keep on hand to be used if symptoms worsen, with instructions to notify the provider if antibiotics are started.1
Continue to: Antibiotic therapy
Antibiotic therapy. The rationale for treating ABRS with antibiotics is to expedite recovery and prevent complications such as periorbital or orbital cellulitis, meningitis, frontal osteomyelitis, cavernous sinus thrombosis, and other serious illness.27 Antibiotic treatment is associated with a shorter duration of symptoms (NNT = 19) but an increased risk of adverse events (NNH = 8).7,19
Amoxicillin with or without clavulanate for 5 to 10 days is first-line antibiotic therapy for most adults with ABRS.1,3,5,8,9,11 Per AAO-HNS, the “justification for amoxicillin as first-line treatment relates to its safety, efficacy, low cost, and narrow microbiologic spectrum.”1 Amoxicillin may be dosed 500 mg tid for 5 to 10 days. Amoxicillin/clavulanate (Augmentin) is recommended for patients with comorbid conditions or with increased risk of bacterial resistance. Dosing for amoxicillin/clavulanate is 500/125 mg tid or 875/125 mg bid for 5 to 10 days. Duration of therapy should be determined by the severity of symptoms.5
For penicillin-allergic patients, doxycycline or a respiratory fluoroquinolone (levofloxacin or moxifloxacin) is considered first-line treatment.1,6 Doxycycline is preferred because of its narrower spectrum and fewer adverse effects than the fluoroquinolones. Fluoroquinolones should be reserved for patients who fail first-line treatment and are penicillin allergic.1 Because of the high rates of resistance among S pneumoniae and H influenzae, macrolides, trimethoprim/sulfamethoxazole (TMP/SMX), and cephalosporins are not recommended as first-line therapy.1,5
How antibiotic options compare. A Cochrane review of 54 studies comparing different antibiotics showed no antibiotic was superior.3 Of the 54 studies, 6 studies (N = 1887) were pooled to compare cephalosporins to amoxicillin/clavulanate at 7 to 15 days. The findings indicated a statistically significant difference for amoxicillin/clavulanate with a relative risk (RR) of 1.37 (confidence interval [CI], 1.04-1.8).3 However, none of these 6 studies were graded as having a low risk of bias; therefore, confidence in this finding was deemed limited due to the quality of included studies. The failure rate for cephalosporins was 12% vs 8% for amoxicillin/clavulanate.3
Treatment failure is considered when a patient has not improved by Day 7 after ABRS diagnosis (with or without medication) or when symptoms worsen at any time. If watchful waiting was chosen and a safety net prescription was provided, the antibiotics should be filled and started. If no antibiotic was prescribed at the time watchful waiting commenced, the patient should return for further evaluation and be started on antibiotics. If antibiotics were prescribed initially for severe symptoms, a change in antibiotic therapy is indicated, and a broader-spectrum antibiotic should be chosen. If amoxicillin was prescribed, the patient should be switched to amoxicillin/clavulanate, doxycycline, a respiratory fluoroquinolone, or a combination of clindamycin plus a third-generation cephalosporin.1

Diagnosis and management of pediatric patients
Diagnosis of ABRS in children is defined as an acute upper respiratory infection (URI) accompanied by persistent nasal discharge, daytime cough for ≥ 10 days without improvement, an episode of “double sickening,” or severe onset with a temperature ≥ 102°F and purulent nasal discharge for 3 days.15
Initial presentations of viral URIs and ABRS are almost identical; thus, persistence of symptoms is key to diagnosis.6 Nasal discharge tends to appear several days after initial symptoms manifest for viral infections including influenza. In children < 5 years of age, the most common complication involves the orbit.15 Orbital complications generally manifest with eye pain and/or periorbital swelling and may be accompanied by proptosis or decreased functioning of extraocular musculature. The differential diagnosis for orbital complications includes cavernous sinus thrombosis, orbital cellulitis/abscess, subperiosteal abscess, and inflammatory edema.27,28 Intracranial complications are also possible with severe ABRS.12
Radiology studies are not recommended for the initial diagnosis of ABRS in children, as again, imaging does not differentiate between viral and bacterial etiologies. However, in children with complications such as orbital or cerebral involvement, a contrast-enhanced CT scan of the paranasal sinuses is indicated.15
Antibiotic therapy is indicated in children with a diagnosis of severe ABRS or in cases of “double sickening.” Clinicians may consider watchful waiting for 3 additional days before initiating antibiotics in patients meeting criteria for ABRS.Amoxicillin with or without clavulanate is the antibiotic of choice.15
For penicillin-allergic children without a history of anaphylactoid reaction, treatment with cefpodoxime, cefdinir, or cefuroxime is appropriate. For children with a history of anaphylaxis, treatment with a combination of clindamycin (or linezolid) and cefixime is indicated. Alternatively, a fluoroquinolone such as levofloxacin may be used, but adverse effects and emerging resistance limit its use.15
Continue to: Specialist referral
Specialist referral
Referral to Otolaryngology is indicated for patients with > 3 episodes of clinically diagnosed bacterial sinusitis in 1 year, evidence of fungal disease (which is outside the scope of this article), immunocompromised status, or a persistent temperature ≥ 102°F despite antibiotic therapy. Also consider otolaryngology referral for patients with a history of sinus surgery.2,5,6

An estimated 30 million cases of acute rhinosinusitis (ARS) occur every year in the United States.1 More than 80% of people with ARS are prescribed antibiotics in North America, accounting for 15% to 20% of all antibiotic prescriptions in the adult outpatient setting.2,3 Many of these prescriptions are unnecessary, as the most common cause of ARS is a virus.4,5 Evidence consistently shows that symptoms of ARS will resolve spontaneously in most patients and that only those patients with severe or prolonged symptoms require consideration of antibiotic therapy.1,2,4,6 Nearly half of all patients will improve within 1 week and two-thirds of patients will improve within 2 weeks without the use of antibiotics.7 In children, only about 6% to 7% presenting with upper respiratory symptoms meet the criteria for acute bacterial rhinosinusitis (ABRS),8 which we’ll detail in a bit. For most patients, treatment should consist of symptom management.5
But what about the minority who require antibiotic therapy? This article reviews how to evaluate patients with ARS, identify those who require antibiotics, and prescribe the most appropriate antibiotic treatment regimens.
Diagnosis: Distinguishing viral from bacterial disease
ARS is defined as the sudden onset of purulent nasal discharge plus either nasal blockage or facial pressure/pain lasting < 4 weeks.3,9 Additional signs and symptoms may include postnasal drip, a reduced sense of smell, sinus tenderness to palpation, and maxillary toothaches.10,11
ARS may be viral or bacterial in etiology, with the most common bacterial organisms being Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.1,3,5 The most common viral causes are influenza, parainfluenza, and rhinovirus. Approximately 90% to 98% of cases of ARS are viral6,11; only about 0.5% to 2% of viral rhinosinusitis episodes are complicated by bacterial infection.1,10-12
Diagnose ABRS when symptoms of ARS fail to improve after 10 days or symptoms of ARS worsen within 10 days after initial improvement (“double sickening”).1,11 Symptoms that are significantly associated with ABRS are unilateral sinus pain and reported maxillary pain. The presence of facial or dental pain correlates with ABRS but does not identify the specific sinus involved.1
There isn’t good correlation between patients saying they have sinusitis and actually having it.13 A 2019 meta-analysis by Ebell et al14 reported that based on limited data, the overall clinical impression, fetid odor on the breath, and pain in the teeth are the best individual clinical predictors of ABRS.
As recommended by the Infectious Disease Society of America (IDSA), a diagnosis of ABRS is also reasonable in patients who present with severe symptoms at the onset.6 Although there is no consensus about what constitutes “severe symptoms,” they are often described as a temperature ≥ 102°F (39°C) plus 3 to 4 days of purulent nasal drainage.1,4,6
Continue to: Additional symptoms of ABRS may include...
Additional symptoms of ABRS may include cough, fatigue, decreased or lack of sense of smell (hyposmia or anosmia), and ear pressure.10 Another sign of “double sickening” is the development of a fever after several days of symptoms.1,9,15 Viral sinusitis typically lasts 5 to 7 days with a peak at days 2 to 3.1,15 If symptoms continue for 10 days, there is a 60% chance of bacterial sinusitis, although some viral rhinosinusitis symptoms persist for > 14 days.1,5 Beyond 4 to 12 weeks, sinusitis is classified as subacute or chronic.3
Physical exam findings and the limited roles of imaging and labs
Common physical exam findings associated with the diagnosis of ABRS include altered speech indicating nasal obstruction; edema or erythema of the skin indicating congested capillaries; tenderness to palpation over the cheeks or upper teeth; odorous breath; and purulent drainage from the nose or in the posterior pharynx.
In a study by Hansen et al13 (N = 174), the only sign that showed significant association with ABRS (diagnosed by sinus aspiration or lavage) was unilateral tenderness of the maxillary sinuses. The presence of purulent drainage in the nose or posterior pharynx also has significant diagnostic value, as it predicts the presence of bacteria on antral aspiration.1 Purulent discharge in the pharynx is associated with a higher likelihood of benefit from antibiotic therapy compared to placebo (number needed to treat [NNT] = 8).16 However, colored nasal discharge indicates the presence of neutrophils—not bacteria—and does not predict the likelihood of bacterial sinus infection.14,17 Therefore, the history and physical exam should focus on location of pain (sinus and/or teeth), duration of symptoms, presence of fever, change in symptom severity, attempted home therapies, sinus tenderness on exam, breath odor, and purulent drainage seen in the nasal cavity or posterior pharynx.13,14
Radiographic imaging has no role in the diagnosis or treatment of uncomplicated ABRS because viral and bacterial etiologies have similar radiographic appearances. Additionally, employing radiologic imaging would increase health care costs by at least 4-fold.5,6,8,17 The American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) clinical practice guidelines recommend against radiographic imaging for patients who meet the diagnostic criteria for ABRS unless concern exists for a complication or an alternate diagnosis is suspected.1 Computed tomography (CT) imaging of the sinuses may be warranted in patients with severe headaches, facial swelling, cranial nerve palsies, or bulging of the eye (proptosis), all of which indicate a potential complication of ABRS.1
Laboratory evaluations. ABRS is a clinical diagnosis; therefore, routine lab work, such as a white blood cell count, C-reactive protein (CRP) level, and/or erythrocyte sedimentation rate (ESR), are not indicated unless an alternate diagnosis is suspected.1,5,13,18,19
Continue to: In one study...
In one study, CRP > 10 mg/L and ESR > 10 mm/h were the strongest individual predictors of purulent antral puncture aspirate or positive bacterial culture of aspirate, which is considered diagnostic for ABRS. 20 However, CRP and ESR by themselves are not adequate to diagnose ABRS.20 This study developed a clinical decision rule that used symptoms, signs, and laboratory values to rate the likelihood of ABRS as being either low, moderate, or high. However, this clinical decision rule has not been prospectively validated.
Thus, CRP and ESR elevations can support the diagnosis of ABRS, but the low sensitivity of these tests precludes their use as a screening tool for ABRS.14,18 Studies by Ebell19 and Huang21 have shown some benefit to dipstick assay of nasal secretions for the diagnosis of ABRS, but this method is not validated or widely used.19,21
Treatment: From managing symptoms to prescribing antibiotics
Overprescribing antibiotics for ARS is a prominent health care issue. In fact, 5 of 9 placebo-controlled studies showed that most people improve within 2 weeks regardless of antibiotic use (N = 1058).3 Therefore, weigh the decision to treat ABRS with antibiotics against the risk for potential adverse reactions and within the context of antibiotic stewardship.2,9,12,22-24 Consider antibiotics only if patients meet the diagnostic criteria for ABRS (TABLE 11,6) or, occasionally, for patients with severe symptoms upon presentation, such as a temperature ≥ 102°F (39°C) plus purulent nasal discharge for 3 to 4 days.1 The most commonly reported adverse effects of antibiotics are gastrointestinal in nature and include nausea, vomiting, and diarrhea.2,9
Symptomatic management for both ARS and ABRS is recommended as first-line therapy; it should be offered to patients before making a diagnosis of ABRS.1,5,9,25 Consider using analgesics, topical intranasal steroids, and/or nasal saline irrigation to alleviate symptoms and improve quality of life.1,5,25 Interventions with questionable or unproven efficacy include the use of antihistamines, systemic steroids, decongestants, and mucolytics, but they may be considered on an individual basis.1 A systematic review found that topical nasal steroids relieved facial pain and nasal congestion in patients with rhinitis and acute sinusitis (NNT = 14).1,26
Even after diagnosing ABRS, clinicians should offer watchful waiting and symptomatic therapies as long as patients have adequate access to follow-up (TABLE 2,1,15FIGURE1,6). Antibiotic therapy can then be initiated if symptoms do not improve after an additional 7 days of watchful waiting or if symptoms worsen at any time. It is reasonable to give patients a prescription to keep on hand to be used if symptoms worsen, with instructions to notify the provider if antibiotics are started.1
Continue to: Antibiotic therapy
Antibiotic therapy. The rationale for treating ABRS with antibiotics is to expedite recovery and prevent complications such as periorbital or orbital cellulitis, meningitis, frontal osteomyelitis, cavernous sinus thrombosis, and other serious illness.27 Antibiotic treatment is associated with a shorter duration of symptoms (NNT = 19) but an increased risk of adverse events (NNH = 8).7,19
Amoxicillin with or without clavulanate for 5 to 10 days is first-line antibiotic therapy for most adults with ABRS.1,3,5,8,9,11 Per AAO-HNS, the “justification for amoxicillin as first-line treatment relates to its safety, efficacy, low cost, and narrow microbiologic spectrum.”1 Amoxicillin may be dosed 500 mg tid for 5 to 10 days. Amoxicillin/clavulanate (Augmentin) is recommended for patients with comorbid conditions or with increased risk of bacterial resistance. Dosing for amoxicillin/clavulanate is 500/125 mg tid or 875/125 mg bid for 5 to 10 days. Duration of therapy should be determined by the severity of symptoms.5
For penicillin-allergic patients, doxycycline or a respiratory fluoroquinolone (levofloxacin or moxifloxacin) is considered first-line treatment.1,6 Doxycycline is preferred because of its narrower spectrum and fewer adverse effects than the fluoroquinolones. Fluoroquinolones should be reserved for patients who fail first-line treatment and are penicillin allergic.1 Because of the high rates of resistance among S pneumoniae and H influenzae, macrolides, trimethoprim/sulfamethoxazole (TMP/SMX), and cephalosporins are not recommended as first-line therapy.1,5
How antibiotic options compare. A Cochrane review of 54 studies comparing different antibiotics showed no antibiotic was superior.3 Of the 54 studies, 6 studies (N = 1887) were pooled to compare cephalosporins to amoxicillin/clavulanate at 7 to 15 days. The findings indicated a statistically significant difference for amoxicillin/clavulanate with a relative risk (RR) of 1.37 (confidence interval [CI], 1.04-1.8).3 However, none of these 6 studies were graded as having a low risk of bias; therefore, confidence in this finding was deemed limited due to the quality of included studies. The failure rate for cephalosporins was 12% vs 8% for amoxicillin/clavulanate.3
Treatment failure is considered when a patient has not improved by Day 7 after ABRS diagnosis (with or without medication) or when symptoms worsen at any time. If watchful waiting was chosen and a safety net prescription was provided, the antibiotics should be filled and started. If no antibiotic was prescribed at the time watchful waiting commenced, the patient should return for further evaluation and be started on antibiotics. If antibiotics were prescribed initially for severe symptoms, a change in antibiotic therapy is indicated, and a broader-spectrum antibiotic should be chosen. If amoxicillin was prescribed, the patient should be switched to amoxicillin/clavulanate, doxycycline, a respiratory fluoroquinolone, or a combination of clindamycin plus a third-generation cephalosporin.1

Diagnosis and management of pediatric patients
Diagnosis of ABRS in children is defined as an acute upper respiratory infection (URI) accompanied by persistent nasal discharge, daytime cough for ≥ 10 days without improvement, an episode of “double sickening,” or severe onset with a temperature ≥ 102°F and purulent nasal discharge for 3 days.15
Initial presentations of viral URIs and ABRS are almost identical; thus, persistence of symptoms is key to diagnosis.6 Nasal discharge tends to appear several days after initial symptoms manifest for viral infections including influenza. In children < 5 years of age, the most common complication involves the orbit.15 Orbital complications generally manifest with eye pain and/or periorbital swelling and may be accompanied by proptosis or decreased functioning of extraocular musculature. The differential diagnosis for orbital complications includes cavernous sinus thrombosis, orbital cellulitis/abscess, subperiosteal abscess, and inflammatory edema.27,28 Intracranial complications are also possible with severe ABRS.12
Radiology studies are not recommended for the initial diagnosis of ABRS in children, as again, imaging does not differentiate between viral and bacterial etiologies. However, in children with complications such as orbital or cerebral involvement, a contrast-enhanced CT scan of the paranasal sinuses is indicated.15
Antibiotic therapy is indicated in children with a diagnosis of severe ABRS or in cases of “double sickening.” Clinicians may consider watchful waiting for 3 additional days before initiating antibiotics in patients meeting criteria for ABRS.Amoxicillin with or without clavulanate is the antibiotic of choice.15
For penicillin-allergic children without a history of anaphylactoid reaction, treatment with cefpodoxime, cefdinir, or cefuroxime is appropriate. For children with a history of anaphylaxis, treatment with a combination of clindamycin (or linezolid) and cefixime is indicated. Alternatively, a fluoroquinolone such as levofloxacin may be used, but adverse effects and emerging resistance limit its use.15

Specialist referral
Referral to Otolaryngology is indicated for patients with > 3 episodes of clinically diagnosed bacterial sinusitis in 1 year, evidence of fungal disease (which is outside the scope of this article), immunocompromised status, or a persistent temperature ≥ 102°F despite antibiotic therapy. Also consider otolaryngology referral for patients with a history of sinus surgery.2,5,6

An estimated 30 million cases of acute rhinosinusitis (ARS) occur every year in the United States.1 More than 80% of people with ARS are prescribed antibiotics in North America, accounting for 15% to 20% of all antibiotic prescriptions in the adult outpatient setting.2,3 Many of these prescriptions are unnecessary, as the most common cause of ARS is a virus.4,5 Evidence consistently shows that symptoms of ARS will resolve spontaneously in most patients and that only those patients with severe or prolonged symptoms require consideration of antibiotic therapy.1,2,4,6 Nearly half of all patients will improve within 1 week and two-thirds of patients will improve within 2 weeks without the use of antibiotics.7 In children, only about 6% to 7% presenting with upper respiratory symptoms meet the criteria for acute bacterial rhinosinusitis (ABRS),8 which we’ll detail in a bit. For most patients, treatment should consist of symptom management.5
But what about the minority who require antibiotic therapy? This article reviews how to evaluate patients with ARS, identify those who require antibiotics, and prescribe the most appropriate antibiotic treatment regimens.
Diagnosis: Distinguishing viral from bacterial disease
ARS is defined as the sudden onset of purulent nasal discharge plus either nasal blockage or facial pressure/pain lasting < 4 weeks.3,9 Additional signs and symptoms may include postnasal drip, a reduced sense of smell, sinus tenderness to palpation, and maxillary toothaches.10,11
ARS may be viral or bacterial in etiology, with the most common bacterial organisms being Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.1,3,5 The most common viral causes are influenza, parainfluenza, and rhinovirus. Approximately 90% to 98% of cases of ARS are viral6,11; only about 0.5% to 2% of viral rhinosinusitis episodes are complicated by bacterial infection.1,10-12
Diagnose ABRS when symptoms of ARS fail to improve after 10 days or symptoms of ARS worsen within 10 days after initial improvement (“double sickening”).1,11 Symptoms that are significantly associated with ABRS are unilateral sinus pain and reported maxillary pain. The presence of facial or dental pain correlates with ABRS but does not identify the specific sinus involved.1
There isn’t good correlation between patients saying they have sinusitis and actually having it.13 A 2019 meta-analysis by Ebell et al14 reported that based on limited data, the overall clinical impression, fetid odor on the breath, and pain in the teeth are the best individual clinical predictors of ABRS.
As recommended by the Infectious Disease Society of America (IDSA), a diagnosis of ABRS is also reasonable in patients who present with severe symptoms at the onset.6 Although there is no consensus about what constitutes “severe symptoms,” they are often described as a temperature ≥ 102°F (39°C) plus 3 to 4 days of purulent nasal drainage.1,4,6
Continue to: Additional symptoms of ABRS may include...
Additional symptoms of ABRS may include cough, fatigue, decreased or lack of sense of smell (hyposmia or anosmia), and ear pressure.10 Another sign of “double sickening” is the development of a fever after several days of symptoms.1,9,15 Viral sinusitis typically lasts 5 to 7 days with a peak at days 2 to 3.1,15 If symptoms continue for 10 days, there is a 60% chance of bacterial sinusitis, although some viral rhinosinusitis symptoms persist for > 14 days.1,5 Beyond 4 to 12 weeks, sinusitis is classified as subacute or chronic.3
Physical exam findings and the limited roles of imaging and labs
Common physical exam findings associated with the diagnosis of ABRS include altered speech indicating nasal obstruction; edema or erythema of the skin indicating congested capillaries; tenderness to palpation over the cheeks or upper teeth; odorous breath; and purulent drainage from the nose or in the posterior pharynx.
In a study by Hansen et al13 (N = 174), the only sign that showed significant association with ABRS (diagnosed by sinus aspiration or lavage) was unilateral tenderness of the maxillary sinuses. The presence of purulent drainage in the nose or posterior pharynx also has significant diagnostic value, as it predicts the presence of bacteria on antral aspiration.1 Purulent discharge in the pharynx is associated with a higher likelihood of benefit from antibiotic therapy compared to placebo (number needed to treat [NNT] = 8).16 However, colored nasal discharge indicates the presence of neutrophils—not bacteria—and does not predict the likelihood of bacterial sinus infection.14,17 Therefore, the history and physical exam should focus on location of pain (sinus and/or teeth), duration of symptoms, presence of fever, change in symptom severity, attempted home therapies, sinus tenderness on exam, breath odor, and purulent drainage seen in the nasal cavity or posterior pharynx.13,14
Radiographic imaging has no role in the diagnosis or treatment of uncomplicated ABRS because viral and bacterial etiologies have similar radiographic appearances. Additionally, employing radiologic imaging would increase health care costs by at least 4-fold.5,6,8,17 The American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) clinical practice guidelines recommend against radiographic imaging for patients who meet the diagnostic criteria for ABRS unless concern exists for a complication or an alternate diagnosis is suspected.1 Computed tomography (CT) imaging of the sinuses may be warranted in patients with severe headaches, facial swelling, cranial nerve palsies, or bulging of the eye (proptosis), all of which indicate a potential complication of ABRS.1
Laboratory evaluations. ABRS is a clinical diagnosis; therefore, routine lab work, such as a white blood cell count, C-reactive protein (CRP) level, and/or erythrocyte sedimentation rate (ESR), are not indicated unless an alternate diagnosis is suspected.1,5,13,18,19
Continue to: In one study...
In one study, CRP > 10 mg/L and ESR > 10 mm/h were the strongest individual predictors of purulent antral puncture aspirate or positive bacterial culture of aspirate, which is considered diagnostic for ABRS. 20 However, CRP and ESR by themselves are not adequate to diagnose ABRS.20 This study developed a clinical decision rule that used symptoms, signs, and laboratory values to rate the likelihood of ABRS as being either low, moderate, or high. However, this clinical decision rule has not been prospectively validated.
Thus, CRP and ESR elevations can support the diagnosis of ABRS, but the low sensitivity of these tests precludes their use as a screening tool for ABRS.14,18 Studies by Ebell19 and Huang21 have shown some benefit to dipstick assay of nasal secretions for the diagnosis of ABRS, but this method is not validated or widely used.19,21
Treatment: From managing symptoms to prescribing antibiotics
Overprescribing antibiotics for ARS is a prominent health care issue. In fact, 5 of 9 placebo-controlled studies showed that most people improve within 2 weeks regardless of antibiotic use (N = 1058).3 Therefore, weigh the decision to treat ABRS with antibiotics against the risk for potential adverse reactions and within the context of antibiotic stewardship.2,9,12,22-24 Consider antibiotics only if patients meet the diagnostic criteria for ABRS (TABLE 11,6) or, occasionally, for patients with severe symptoms upon presentation, such as a temperature ≥ 102°F (39°C) plus purulent nasal discharge for 3 to 4 days.1 The most commonly reported adverse effects of antibiotics are gastrointestinal in nature and include nausea, vomiting, and diarrhea.2,9
Symptomatic management for both ARS and ABRS is recommended as first-line therapy; it should be offered to patients before making a diagnosis of ABRS.1,5,9,25 Consider using analgesics, topical intranasal steroids, and/or nasal saline irrigation to alleviate symptoms and improve quality of life.1,5,25 Interventions with questionable or unproven efficacy include the use of antihistamines, systemic steroids, decongestants, and mucolytics, but they may be considered on an individual basis.1 A systematic review found that topical nasal steroids relieved facial pain and nasal congestion in patients with rhinitis and acute sinusitis (NNT = 14).1,26
Even after diagnosing ABRS, clinicians should offer watchful waiting and symptomatic therapies as long as patients have adequate access to follow-up (TABLE 2,1,15FIGURE1,6). Antibiotic therapy can then be initiated if symptoms do not improve after an additional 7 days of watchful waiting or if symptoms worsen at any time. It is reasonable to give patients a prescription to keep on hand to be used if symptoms worsen, with instructions to notify the provider if antibiotics are started.1
Continue to: Antibiotic therapy
Antibiotic therapy. The rationale for treating ABRS with antibiotics is to expedite recovery and prevent complications such as periorbital or orbital cellulitis, meningitis, frontal osteomyelitis, cavernous sinus thrombosis, and other serious illness.27 Antibiotic treatment is associated with a shorter duration of symptoms (NNT = 19) but an increased risk of adverse events (NNH = 8).7,19
Amoxicillin with or without clavulanate for 5 to 10 days is first-line antibiotic therapy for most adults with ABRS.1,3,5,8,9,11 Per AAO-HNS, the “justification for amoxicillin as first-line treatment relates to its safety, efficacy, low cost, and narrow microbiologic spectrum.”1 Amoxicillin may be dosed 500 mg tid for 5 to 10 days. Amoxicillin/clavulanate (Augmentin) is recommended for patients with comorbid conditions or with increased risk of bacterial resistance. Dosing for amoxicillin/clavulanate is 500/125 mg tid or 875/125 mg bid for 5 to 10 days. Duration of therapy should be determined by the severity of symptoms.5
For penicillin-allergic patients, doxycycline or a respiratory fluoroquinolone (levofloxacin or moxifloxacin) is considered first-line treatment.1,6 Doxycycline is preferred because of its narrower spectrum and fewer adverse effects than the fluoroquinolones. Fluoroquinolones should be reserved for patients who fail first-line treatment and are penicillin allergic.1 Because of the high rates of resistance among S pneumoniae and H influenzae, macrolides, trimethoprim/sulfamethoxazole (TMP/SMX), and cephalosporins are not recommended as first-line therapy.1,5
How antibiotic options compare. A Cochrane review of 54 studies comparing different antibiotics showed no antibiotic was superior.3 Of the 54 studies, 6 studies (N = 1887) were pooled to compare cephalosporins to amoxicillin/clavulanate at 7 to 15 days. The findings indicated a statistically significant difference for amoxicillin/clavulanate with a relative risk (RR) of 1.37 (confidence interval [CI], 1.04-1.8).3 However, none of these 6 studies were graded as having a low risk of bias; therefore, confidence in this finding was deemed limited due to the quality of included studies. The failure rate for cephalosporins was 12% vs 8% for amoxicillin/clavulanate.3
Treatment failure is considered when a patient has not improved by Day 7 after ABRS diagnosis (with or without medication) or when symptoms worsen at any time. If watchful waiting was chosen and a safety net prescription was provided, the antibiotics should be filled and started. If no antibiotic was prescribed at the time watchful waiting commenced, the patient should return for further evaluation and be started on antibiotics. If antibiotics were prescribed initially for severe symptoms, a change in antibiotic therapy is indicated, and a broader-spectrum antibiotic should be chosen. If amoxicillin was prescribed, the patient should be switched to amoxicillin/clavulanate, doxycycline, a respiratory fluoroquinolone, or a combination of clindamycin plus a third-generation cephalosporin.1

PRACTICE RECOMMENDATIONS
› Reserve antibiotics for patients who meet diagnostic criteria for acute bacterial rhinosinusitis (ABRS). Patients must have purulent nasal drainage that is accompanied by either nasal obstruction or facial pain/pressure/fullness and EITHER symptoms that persist without improvement for at least 10 days OR symptoms that worsen within 10 days of initial improvement (“double sickening”). A
› Offer watchful waiting and delay antibiotics for up to 7 days after diagnosing ABRS in a patient if adequate access to follow-up is available; otherwise, treat with amoxicillin (with or without clavulanate) for 5 to 10 days. A

Passing on the “FastPass”
As part of the COVID-19 pandemic, I see signs everywhere saying they have perks for health care workers. I can go to the front of the line at Costco, or for takeout at a restaurant, or to checkout at the grocery store. Certainly it would be easy, I always have my hospital ID in my car.
I have no interest in doing so. None.
As I’ve previously written, I’m in the back seat right now. For me to take out my hospital ID and grandstand to get in front of the line is not only a lie, but takes away from someone – a nurse, a paramedic, another doctor, whatever – who actually is on the front line of the pandemic and may be in a hurry to get home or back to work.
Me? I may be a doctor, but certainly not part of fighting the pandemic (unless you count wearing a mask and washing my hands frequently as such). I’m here for anyone who needs a neurologist, and my office is open, but that’s always been my normal day at work. I’m not at the hospital, or a screening center, or urgent care.
To me it seems pretty hypocritical, or at least inappropriate, for me to take advantage of a “FastPass” (as Disneyland calls it) when I’m really not one of the people it is intended for.
Perhaps it’s a minor point, but I have three kids, and part of raising them is leading by example. Don’t take something that isn’t yours.
Which is what it would feel like to me.

As part of the COVID-19 pandemic, I see signs everywhere saying they have perks for health care workers. I can go to the front of the line at Costco, or for takeout at a restaurant, or to checkout at the grocery store. Certainly it would be easy, I always have my hospital ID in my car.
I have no interest in doing so. None.
As I’ve previously written, I’m in the back seat right now. For me to take out my hospital ID and grandstand to get in front of the line is not only a lie, but takes away from someone – a nurse, a paramedic, another doctor, whatever – who actually is on the front line of the pandemic and may be in a hurry to get home or back to work.
Me? I may be a doctor, but certainly not part of fighting the pandemic (unless you count wearing a mask and washing my hands frequently as such). I’m here for anyone who needs a neurologist, and my office is open, but that’s always been my normal day at work. I’m not at the hospital, or a screening center, or urgent care.
To me it seems pretty hypocritical, or at least inappropriate, for me to take advantage of a “FastPass” (as Disneyland calls it) when I’m really not one of the people it is intended for.
Perhaps it’s a minor point, but I have three kids, and part of raising them is leading by example. Don’t take something that isn’t yours.
Which is what it would feel like to me.

Managing a woman with BRCA mutations? Shared decision-making is key
CASE
Sara T* recently moved back to the area to be closer to her family. The 34-year-old patient visited our office to discuss the benefits and potential risks of genetic counseling. She explained that her aunt had just died at age 64 of ovarian cancer. Also, her maternal cousin had been diagnosed at age 42 with breast cancer, and her maternal grandmother had died at age 45 of an unknown “female cancer.” She was scared to find out if she had high-risk genes because she felt it would change her life forever. However, if she ignored the issue, she thought she might worry too much.
We discussed the implications of a positive result, such as having to live with the knowledge and to make decisions about potential screening and risk-reducing surgery. On the other hand, not knowing could allow for the undetected growth of cancer that might otherwise be mitigated to some degree if she knew her risk status and pursued an aggressive screening program.
We worked with Ms. T to map out her next steps.
*The patient’s name has been changed to protect her identity.
Breast cancer is the most commonly diagnosed cancer in women worldwide, representing nearly one-quarter of all female cancer diagnoses in 2018.1 It is the second-leading cause of cancer death in women in developed nations and the leading cause of cancer death in women in developing nations.1 In the United States, 1 in 8 women will develop breast cancer in her lifetime.2 By comparison, the rate of ovarian cancer is much lower, with a lifetime prevalence of 1 in 70 to 80 women.3,4 Although ovarian cancer is less common than breast cancer, its associated mortality is high, and most cases are discovered at advanced stages.
The outsized threat of BRCA mutations. It is estimated that 5% to 10% of all breast cancers are hereditary, with 80% of these attributable to BRCA1 (45%) and BRCA2 (35%).5 These autosomal dominant mutations occur at the germline level, within the egg or sperm, and are therefore incorporated into the DNA of every cell and passed from one generation to the next. Families with BRCA mutations have much higher lifetime rates of cancer. The lifetime risk of breast cancer due to BRCA mutations is estimated at > 80% (BRCA1) and 45% (BRCA2).5BRCA mutations account for between
Male BRCA carriers have a lifetime breast cancer risk of 1% to 5% with BRCA1 and 5% to 10% with BRCA2,7,8 compared with about 1:1000 lifetime incidence in the unselected male population. Male carriers are also at risk for more aggressive prostate cancers.7,8
Continue to: Certain populatiosn carry undue burden of BRCA-related disease
Certain populations carry undue burden of BRCA-related disease due to specific founder mutations. While the estimated global prevalence of BRCA mutations is 0.2% to 1%, for those of Ashkenazi Jewish descent the range is 2% to 3%, representing a relative risk up to 15 times that of the general population.9 Hispanic Americans also appear to have higher rates of BRCA-related cancers.10 Ongoing genetics research continues to identify founder mutations worldwide,10 which may inform future screening guidelines.
In addition to BRCA mutations, there are other, less common mutations (TABLE 15) known to cause hereditary breast and ovarian cancer.
Identifying BRCA genes enables treatment planning. Compared with sporadic cancers, BRCA-related breast cancers
Similarly, BRCA-related ovarian cancer is more likely to be high-grade and endometrioid or serous subtype.14
Shared decision-making helps give clarity to the way forward
Shared decision-making is a process of communication whereby the clinician and the patient identify a decision to be made, review data relevant to clinical options, discuss patient perspectives and preferences regarding each option, and arrive at the decision together.17 Shared decision-making is important when treating women with BRCA mutations because there is no single correct plan. Individual values and competing medical issues may strongly guide each woman’s decisions about screening and cancer prevention treatment decisions.
Continue to: Shared decision-making in this situation...
Shared decision-making in this situation is a strategy to use the evidence of risk along with patient preferences around fertility issues to help come to a decision that is the right one for the patient. Primary care clinicians aware of the general risks and benefits of each available option can refer women at high risk for breast or ovarian cancer to a specialist multidisciplinary clinic that can provide tailored risk assessment and risk reduction counseling as needed.18-20
Genetic screening recommendations
Screening is recommended for women who have any 1 of several family risk factors (TABLE 221). A number of risk assessment tools are available for primary care clinicians to determine which patients are at high enough risk for a hereditary breast or ovarian cancer to warrant referral to a genetic counselor.22-25 If screening suggests high risk, the US Preventive Services Task Force (USPSTF) recommends (Grade B) referral for genetic counseling.21
Explain to patients who are candidates for further investigation that a genetic counselor will review their family history and recommend testing for the specific mutations that increase cancer risk. Discuss potential benefits and harms of genetic testing. A benefit of genetic testing is that aggressive screening may suggest preventive procedures to reduce the risk of future cancer. Most tests come back definitively positive or negative, but an indeterminate result may cause harm. A small minority of results may indicate a genetic variant of unknown significance. The ramifications of this variant may not be known. Some women will experience anxiety about nonspecific test results and will be afraid to share them with family members. There is also some concern about privacy issues, potential insurance bias, and coverage of any preventive strategies.26
CASE
Based on Ms. T’s family history and her desire to know more, we referred her to a genetic counselor and she decided to undergo genetic testing. She screened positive for BRCA1. Ms. T was in a serious relationship and thought she would like to have children at some point. She returned to our office after receiving the positive genetic test results, wondering about screening for breast and ovarian cancer.
Breast cancer screening and risk-reduction strategies
Screening. Because the risk of breast cancer is high in women with BRCA mutations, and because cancer in these women is more likely to be advanced at diagnosis, starting a screening program at an early age is prudent. Observational studies suggest that breastfeeding reduces the risk of breast and ovarian cancer in women with BRCA mutations, as it does for women in the general population.27 Women should return for a clinical breast exam every 6 to 12 months starting at age 25; they should start radiologic screening with magnetic resonance imaging at age 25 and mammography at age 30 (TABLE 327,28).
Continue to: Risk-reduction strategies
Risk-reduction strategies. There is weak evidence to support the use of tamoxifen or other synthetic estrogen reuptake modulators (SERMs) to reduce breast cancer risk in women with BRCA mutations. Many of these cancers do not express estrogen receptors, which may explain the lack of efficacy in certain cases. Several observational studies have shown that tamoxifen can reduce the risk of contralateral breast cancer in women with BRCA mutations who have already been diagnosed with cancer in the other breast.29-31 However, tamoxifen does not reduce a patient’s risk of ovarian cancer, and it may increase her risk of uterine cancer.
Prophylactic bilateral mastectomy is the mainstay of breast cancer prevention in this population. Data from a systematic review suggest that this surgery may prevent the incidence of breast cancer in women with BRCA mutations by 90% to 95%.32 However, this review did not demonstrate a reduction in mortality from breast cancer, likely due to poor data quality.32 The National Comprehensive Cancer Network (NCCN) recommends discussing prophylactic mastectomy with all women who have BRCA mutations.28 Further conversations are important to review the risk of tissue left behind and quality-of-life issues, including the inability to breastfeed if the woman wants more children and the cosmetic changes with reconstruction.
Ovarian cancer screening and risk-reduction strategies
Screening. No effective screening strategy has been endorsed for ovarian cancer, as most previous studies have shown screening to be ineffective.26,33 Recently, studies both in the United Kingdom and the United States have investigated a screening strategy using the risk-of-ovarian-cancer algorithm (ROCA), which calculates an individual’s risk based on serum levels of cancer antigen 125 (CA-125).34,35 These studies measured CA-125 levels every 3 to 4 months followed by transvaginal ultrasound if CA-125 increased substantially (as determined by ROCA). Absent an abnormal increase in CA-125, transvaginal ultrasound was performed annually. These screening strategies showed improved specificity over annual screening programs, and the cancers detected were more likely to be diagnosed at an early stage (stage II vs stage III) and had higher rates of zero residual disease after surgery compared with those detected 1 year after screening ended.34,35 However, survival data are not yet available. More research is needed to determine if more frequent screening approaches could improve survival in high-risk women.
NCCN and the American College of Obstetricians and Gynecologists (ACOG) do not endorse routine screening with transvaginal ultrasound and serum CA-125 for high-risk women, as the benefits are uncertain. However, they do advise that these screens may be considered as a short-term strategy for women ages 30 to 35 who defer risk-reducing surgery.26,36 The USPSTF does not make a recommendation regarding ovarian cancer screening in high-risk women.37
Risk-reduction strategies. Risk-reducing bilateral salpingo-oophorectomy (RRSO) is the only recommended technique for reducing the risk of ovarian cancer in women at high risk.26,33,36 Meta-analyses have shown an 80% reduction in ovarian cancer risk16 and 68% reduction in all-cause mortality with this approach.38 The NCCN recommends RRSO for women with a known BRCA1 mutation between the ages of 35 and 40 who have completed childbearing.36 Since the onset of ovarian cancer tends to be later in women with BRCA2 mutations, it is reasonable to delay RRSO until age 40 to 45 in this population if they have taken other steps to maximize breast cancer prevention (ie, bilateral mastectomy).36
Continue to: Adverse effects of RRSO...
Adverse effects of RRSO include surgery complications (wound infection, small bowel obstruction, bladder perforation) and effects of early menopause (vasomotor symptoms, decreased sexual functioning, and increased risk of osteoporosis, cardiovascular disease, and all-cause mortality).39-41 In the absence of contraindications, ACOG recommends using hormone therapy in women undergoing RRSO until the natural age of menopause,42 particularly if their breast tissue has been removed.
Salpingectomy as an alternative. In an attempt to reduce these adverse effects of early menopause, and because a large proportion of high-grade serous tumors originate in the fallopian tube,43 interest has increased in the use of risk-reducing salpingectomy (removal of fallopian tubes) and delayed oophorectomy in women at high risk of ovarian cancer.42 Studies have shown this may be a cost-effective approach and an acceptable alternative in BRCA mutation carriers who are unwilling to undergo RRSO.44,45 A clinical trial investigating this approach in women with BRCA mutations is currently underway in the United States.46 Many centers offer salpingectomy to high-risk patients < 40 years old, understanding that ovary removal is an eventuality for these patients.
When oral contraceptive pills might be beneficial. In younger women with BRCA mutations, there may also be a role for oral contraceptive pills (OCPs) as a risk-reducing strategy. Meta-analyses have shown an approximately 50% reduction in the risk of ovarian cancer among women with BRCA mutations who use OCPs.47-49
ACOG advises that it is appropriate for women with BRCA mutations to use oral contraceptives if indicated (for pregnancy prevention or menstrual cycle regulation), and that it is reasonable to use them for cancer prevention.26 NCCN does not make a formal recommendation, although it does state OCPs may reduce the risk of ovarian cancer in women with a BRCA mutation.36 Case-control studies have produced conflicting data on the association between OCP use and breast cancer risk in BRCA mutation carriers,50-53 although 2 meta-analyses found no significant association in this population.47,48
Decision aids for women with BRCA mutations
Decision aids are visual displays of risk that help patients work through complex decisions. Most decision aids are in print or digital format and include information about the decision to be made as well as pictorial examples of possible outcomes. Pictographs are especially helpful in communicating information. Some decision aids for women with BRCA mutations can be complicated with multiple outcomes (ie, breast cancer and ovarian cancer) and multiple potential interventions (risk-reducing surgery, enhanced screening options).54
Continue to: A Cochrane review...
A Cochrane review found that decision aids increased patients’ knowledge, helped patients clarify their values, and may improve value-concordant decisions.55 Two papers describing the use of decision aids for women with BRCA mutations56,57 documented decreased decisional conflict and increased satisfaction.
CASE
Ms. T underwent the recommended mammogram and MRI screening for breast cancer, as well as testing with serum CA-125 and ultrasound examinations for ovarian cancer. Her initial mammogram and MRI revealed early stage, triple-negative right breast cancer. She chose to undergo bilateral mastectomy and reconstruction. She has now completed treatment and continues to work closely with her oncology team for appropriate breast follow-up.
One year after her initial diagnosis, at the age of 35, she returned to discuss fertility. She was recently married, and she and her husband wanted to start having children. She was concerned about a safe timeline for her to pursue pregnancy, saying she felt “like a ticking time-bomb” given her prior cancer and carrier status. She wanted to discuss the risks and benefits of pregnancy and when she should consider prophylactic oophorectomy. She had a few options. She could have a baby and then undergo an RRSO, or she could talk to her gynecologist about having a salpingectomy to reduce her risk now and use assisted reproductive technology to get pregnant. She could also freeze eggs or embryos, have an RRSO, and then use a surrogate to get pregnant. We informed her that pregnancy would not affect her risk of ovarian cancer and discussed the options for pre-implantation genetic testing to assure that her children would not carry the genetic mutation.58
We provided Ms. T and her husband with a decision aid to help them navigate the decision. They are currently evaluating the options and said they would let us know when they made a decision.

Certain populations carry undue burden of BRCA-related disease due to specific founder mutations. While the estimated global prevalence of BRCA mutations is 0.2% to 1%, for those of Ashkenazi Jewish descent the range is 2% to 3%, representing a relative risk up to 15 times that of the general population.9 Hispanic Americans also appear to have higher rates of BRCA-related cancers.10 Ongoing genetics research continues to identify founder mutations worldwide,10 which may inform future screening guidelines.
In addition to BRCA mutations, there are other, less common mutations (TABLE 15) known to cause hereditary breast and ovarian cancer.
Identifying BRCA genes enables treatment planning. Compared with sporadic cancers, BRCA-related breast cancers
Similarly, BRCA-related ovarian cancer is more likely to be high-grade and endometrioid or serous subtype.14
Shared decision-making helps give clarity to the way forward
Shared decision-making is a process of communication whereby the clinician and the patient identify a decision to be made, review data relevant to clinical options, discuss patient perspectives and preferences regarding each option, and arrive at the decision together.17 Shared decision-making is important when treating women with BRCA mutations because there is no single correct plan. Individual values and competing medical issues may strongly guide each woman’s decisions about screening and cancer prevention treatment decisions.
Continue to: Shared decision-making in this situation...
Shared decision-making in this situation is a strategy to use the evidence of risk along with patient preferences around fertility issues to help come to a decision that is the right one for the patient. Primary care clinicians aware of the general risks and benefits of each available option can refer women at high risk for breast or ovarian cancer to a specialist multidisciplinary clinic that can provide tailored risk assessment and risk reduction counseling as needed.18-20
Genetic screening recommendations
Screening is recommended for women who have any 1 of several family risk factors (TABLE 221). A number of risk assessment tools are available for primary care clinicians to determine which patients are at high enough risk for a hereditary breast or ovarian cancer to warrant referral to a genetic counselor.22-25 If screening suggests high risk, the US Preventive Services Task Force (USPSTF) recommends (Grade B) referral for genetic counseling.21
Explain to patients who are candidates for further investigation that a genetic counselor will review their family history and recommend testing for the specific mutations that increase cancer risk. Discuss potential benefits and harms of genetic testing. A benefit of genetic testing is that aggressive screening may suggest preventive procedures to reduce the risk of future cancer. Most tests come back definitively positive or negative, but an indeterminate result may cause harm. A small minority of results may indicate a genetic variant of unknown significance. The ramifications of this variant may not be known. Some women will experience anxiety about nonspecific test results and will be afraid to share them with family members. There is also some concern about privacy issues, potential insurance bias, and coverage of any preventive strategies.26
CASE
Based on Ms. T’s family history and her desire to know more, we referred her to a genetic counselor and she decided to undergo genetic testing. She screened positive for BRCA1. Ms. T was in a serious relationship and thought she would like to have children at some point. She returned to our office after receiving the positive genetic test results, wondering about screening for breast and ovarian cancer.
Breast cancer screening and risk-reduction strategies
Screening. Because the risk of breast cancer is high in women with BRCA mutations, and because cancer in these women is more likely to be advanced at diagnosis, starting a screening program at an early age is prudent. Observational studies suggest that breastfeeding reduces the risk of breast and ovarian cancer in women with BRCA mutations, as it does for women in the general population.27 Women should return for a clinical breast exam every 6 to 12 months starting at age 25; they should start radiologic screening with magnetic resonance imaging at age 25 and mammography at age 30 (TABLE 327,28).
Continue to: Risk-reduction strategies
Risk-reduction strategies. There is weak evidence to support the use of tamoxifen or other synthetic estrogen reuptake modulators (SERMs) to reduce breast cancer risk in women with BRCA mutations. Many of these cancers do not express estrogen receptors, which may explain the lack of efficacy in certain cases. Several observational studies have shown that tamoxifen can reduce the risk of contralateral breast cancer in women with BRCA mutations who have already been diagnosed with cancer in the other breast.29-31 However, tamoxifen does not reduce a patient’s risk of ovarian cancer, and it may increase her risk of uterine cancer.
Prophylactic bilateral mastectomy is the mainstay of breast cancer prevention in this population. Data from a systematic review suggest that this surgery may prevent the incidence of breast cancer in women with BRCA mutations by 90% to 95%.32 However, this review did not demonstrate a reduction in mortality from breast cancer, likely due to poor data quality.32 The National Comprehensive Cancer Network (NCCN) recommends discussing prophylactic mastectomy with all women who have BRCA mutations.28 Further conversations are important to review the risk of tissue left behind and quality-of-life issues, including the inability to breastfeed if the woman wants more children and the cosmetic changes with reconstruction.
Ovarian cancer screening and risk-reduction strategies
Screening. No effective screening strategy has been endorsed for ovarian cancer, as most previous studies have shown screening to be ineffective.26,33 Recently, studies both in the United Kingdom and the United States have investigated a screening strategy using the risk-of-ovarian-cancer algorithm (ROCA), which calculates an individual’s risk based on serum levels of cancer antigen 125 (CA-125).34,35 These studies measured CA-125 levels every 3 to 4 months followed by transvaginal ultrasound if CA-125 increased substantially (as determined by ROCA). Absent an abnormal increase in CA-125, transvaginal ultrasound was performed annually. These screening strategies showed improved specificity over annual screening programs, and the cancers detected were more likely to be diagnosed at an early stage (stage II vs stage III) and had higher rates of zero residual disease after surgery compared with those detected 1 year after screening ended.34,35 However, survival data are not yet available. More research is needed to determine if more frequent screening approaches could improve survival in high-risk women.
NCCN and the American College of Obstetricians and Gynecologists (ACOG) do not endorse routine screening with transvaginal ultrasound and serum CA-125 for high-risk women, as the benefits are uncertain. However, they do advise that these screens may be considered as a short-term strategy for women ages 30 to 35 who defer risk-reducing surgery.26,36 The USPSTF does not make a recommendation regarding ovarian cancer screening in high-risk women.37
Risk-reduction strategies. Risk-reducing bilateral salpingo-oophorectomy (RRSO) is the only recommended technique for reducing the risk of ovarian cancer in women at high risk.26,33,36 Meta-analyses have shown an 80% reduction in ovarian cancer risk16 and 68% reduction in all-cause mortality with this approach.38 The NCCN recommends RRSO for women with a known BRCA1 mutation between the ages of 35 and 40 who have completed childbearing.36 Since the onset of ovarian cancer tends to be later in women with BRCA2 mutations, it is reasonable to delay RRSO until age 40 to 45 in this population if they have taken other steps to maximize breast cancer prevention (ie, bilateral mastectomy).36
Continue to: Adverse effects of RRSO...
Adverse effects of RRSO include surgery complications (wound infection, small bowel obstruction, bladder perforation) and effects of early menopause (vasomotor symptoms, decreased sexual functioning, and increased risk of osteoporosis, cardiovascular disease, and all-cause mortality).39-41 In the absence of contraindications, ACOG recommends using hormone therapy in women undergoing RRSO until the natural age of menopause,42 particularly if their breast tissue has been removed.
Salpingectomy as an alternative. In an attempt to reduce these adverse effects of early menopause, and because a large proportion of high-grade serous tumors originate in the fallopian tube,43 interest has increased in the use of risk-reducing salpingectomy (removal of fallopian tubes) and delayed oophorectomy in women at high risk of ovarian cancer.42 Studies have shown this may be a cost-effective approach and an acceptable alternative in BRCA mutation carriers who are unwilling to undergo RRSO.44,45 A clinical trial investigating this approach in women with BRCA mutations is currently underway in the United States.46 Many centers offer salpingectomy to high-risk patients < 40 years old, understanding that ovary removal is an eventuality for these patients.
When oral contraceptive pills might be beneficial. In younger women with BRCA mutations, there may also be a role for oral contraceptive pills (OCPs) as a risk-reducing strategy. Meta-analyses have shown an approximately 50% reduction in the risk of ovarian cancer among women with BRCA mutations who use OCPs.47-49
ACOG advises that it is appropriate for women with BRCA mutations to use oral contraceptives if indicated (for pregnancy prevention or menstrual cycle regulation), and that it is reasonable to use them for cancer prevention.26 NCCN does not make a formal recommendation, although it does state OCPs may reduce the risk of ovarian cancer in women with a BRCA mutation.36 Case-control studies have produced conflicting data on the association between OCP use and breast cancer risk in BRCA mutation carriers,50-53 although 2 meta-analyses found no significant association in this population.47,48
Decision aids for women with BRCA mutations
Decision aids are visual displays of risk that help patients work through complex decisions. Most decision aids are in print or digital format and include information about the decision to be made as well as pictorial examples of possible outcomes. Pictographs are especially helpful in communicating information. Some decision aids for women with BRCA mutations can be complicated with multiple outcomes (ie, breast cancer and ovarian cancer) and multiple potential interventions (risk-reducing surgery, enhanced screening options).54
Continue to: A Cochrane review...
A Cochrane review found that decision aids increased patients’ knowledge, helped patients clarify their values, and may improve value-concordant decisions.55 Two papers describing the use of decision aids for women with BRCA mutations56,57 documented decreased decisional conflict and increased satisfaction.
CASE
Ms. T underwent the recommended mammogram and MRI screening for breast cancer, as well as testing with serum CA-125 and ultrasound examinations for ovarian cancer. Her initial mammogram and MRI revealed early stage, triple-negative right breast cancer. She chose to undergo bilateral mastectomy and reconstruction. She has now completed treatment and continues to work closely with her oncology team for appropriate breast follow-up.
One year after her initial diagnosis, at the age of 35, she returned to discuss fertility. She was recently married, and she and her husband wanted to start having children. She was concerned about a safe timeline for her to pursue pregnancy, saying she felt “like a ticking time-bomb” given her prior cancer and carrier status. She wanted to discuss the risks and benefits of pregnancy and when she should consider prophylactic oophorectomy. She had a few options. She could have a baby and then undergo an RRSO, or she could talk to her gynecologist about having a salpingectomy to reduce her risk now and use assisted reproductive technology to get pregnant. She could also freeze eggs or embryos, have an RRSO, and then use a surrogate to get pregnant. We informed her that pregnancy would not affect her risk of ovarian cancer and discussed the options for pre-implantation genetic testing to assure that her children would not carry the genetic mutation.58
We provided Ms. T and her husband with a decision aid to help them navigate the decision. They are currently evaluating the options and said they would let us know when they made a decision.

CASE
Sara T* recently moved back to the area to be closer to her family. The 34-year-old patient visited our office to discuss the benefits and potential risks of genetic counseling. She explained that her aunt had just died at age 64 of ovarian cancer. Also, her maternal cousin had been diagnosed at age 42 with breast cancer, and her maternal grandmother had died at age 45 of an unknown “female cancer.” She was scared to find out if she had high-risk genes because she felt it would change her life forever. However, if she ignored the issue, she thought she might worry too much.
We discussed the implications of a positive result, such as having to live with the knowledge and to make decisions about potential screening and risk-reducing surgery. On the other hand, not knowing could allow for the undetected growth of cancer that might otherwise be mitigated to some degree if she knew her risk status and pursued an aggressive screening program.
We worked with Ms. T to map out her next steps.

Breast cancer is the most commonly diagnosed cancer in women worldwide, representing nearly one-quarter of all female cancer diagnoses in 2018.1 It is the second-leading cause of cancer death in women in developed nations and the leading cause of cancer death in women in developing nations.1 In the United States, 1 in 8 women will develop breast cancer in her lifetime.2 By comparison, the rate of ovarian cancer is much lower, with a lifetime prevalence of 1 in 70 to 80 women.3,4 Although ovarian cancer is less common than breast cancer, its associated mortality is high, and most cases are discovered at advanced stages.
The outsized threat of BRCA mutations. It is estimated that 5% to 10% of all breast cancers are hereditary, with 80% of these attributable to BRCA1 (45%) and BRCA2 (35%).5 These autosomal dominant mutations occur at the germline level, within the egg or sperm, and are therefore incorporated into the DNA of every cell and passed from one generation to the next. Families with BRCA mutations have much higher lifetime rates of cancer. The lifetime risk of breast cancer due to BRCA mutations is estimated at > 80% (BRCA1) and 45% (BRCA2).5BRCA mutations account for between
Male BRCA carriers have a lifetime breast cancer risk of 1% to 5% with BRCA1 and 5% to 10% with BRCA2,7,8 compared with about 1:1000 lifetime incidence in the unselected male population. Male carriers are also at risk for more aggressive prostate cancers.7,8

PRACTICE RECOMMENDATIONS
› Recommend genetic screening for the BRCA mutation if a patient’s family history includes a breast cancer diagnosis before age 50, occurrences of both breast and ovarian cancers, or other suggestive features. C
› Advise women with the BRCA gene to return for a clinical breast exam every 6 to 12 months starting at age 25, and to start radiologic screening at age 30. C
› Consider recommending bilateral salpingo-oophorectomy to prevent ovarian cancer in women 35 to 40 years of age with a BRCA1 mutation who have completed childbearing. C
Strength of recommendation (SOR)
A Good-quality patient-oriented evidence
B Inconsistent or limited-quality patient-oriented evidence
C Consensus, usual practice, opinion, disease-oriented evidence, case series
