The first death to occur in a patient with severe lung illness associated with e-cigarette product use has been reported in Illinois, officials announced at a Centers for Disease Control and Prevention telebriefing.

The cause for the mysterious lung illnesses has not been determined, but an infectious disease does not appear to be implicated. As of yesterday, 193 potential cases have been identified in 22 states since June 28.

No specific product has been implicated in all cases, and it is unclear if there is a common cause or if these are several diseases with a similar presentation.

Wisconsin and Illinois have asked the CDC to directly assist them in their investigations of cases. Other states are handling their own investigations. Further information is available from the CDC at cdc.gov/e-cigarettes.

There have been 22 cases of the illness in Illinois and an additional 12 individuals are being evaluated as possible cases, according to Jennifer Layden, MD, PhD, chief medical officer and state epidemiologist, Illinois Department of Public Health.

Illinois is working with the CDC and the Food and Drug Administration to investigate devices that affected patients have used. No specific product has been implicated across all cases; all patients have reported vaping in recent months Several patients in Illinois have reported using tetrahydrocannabinol (THC) product oils, but Dr. Layden reiterated the investigations are reliant on information reported by affected patients only.

Mitch Zeller, JD, director, Center for Tobacco Products at the FDA, said product samples from a number of states are being evaluated to determine their contents. The FDA is examining samples sent and trying to identify product contents.

The cases reported to date have been in adults aged 17-38 years and have occurred primarily men. The investigation is in a relatively early stage and is working with incomplete case reports. These will become standardized to include more specific information, such as the name of the product, where it was purchased, and whether it was used as intended or whether other products were added, he said.

As e-cigarettes are not a new product, it’s possible that cases of this illness has been occurring but that the link was not recognized, and the cases were neither captured nor reported, said Brian King, PhD, MPH, deputy director, Research Translation, Office on Smoking and Health, CDC. He noted that e-cigarettes may contain “a variety of constituents that could be problematic in terms of pulmonary illness,” such as ingredients in certain flavorings and ultrafine particulates.

The agencies are now trying to harmonize reporting across all states so cases can be evaluated in a more standardized way. Information on standardized reporting on a national level will be issued in the next few days, according to the CDC.

The CDC notified U.S. health care systems and clinicians about the illnesses and what to watch for via a Clinician Outreach and Communication Activity Clinical Action Message.

In general, patients have reported a gradual onset of symptoms including shortness of breath or chest pain that increased over days or weeks before hospital admission. Gastrointestinal symptoms including vomiting, diarrhea, and fatigue have been reported by some.

More than 1,625 pediatricians have applied to take the first pediatric hospitalist certification exam in November 2019, and approximately 93% of them have been accepted, according to a statement from the American Board of Pediatrics.

It was the rejection of the 7%, however, that set off a firestorm on the electronic discussion board for American Academy of Pediatrics (AAP) hospital medicine this summer, and led to a petition to the board to revise its eligibility requirements, ensure that the requirements are fair to women, and bring transparency to its decision process. The petition has more than 1,400 signatures.

Seattle Children’s Hospital and Yale New Haven (Conn.) Children’s Hospital have both said they will not consider board certification in hiring decisions until the situation is resolved.

The American Board of Pediatrics (ABP) declined an interview request pending its formal response to the Aug. 6 petition, but in a statement to this news organization, executive vice president Suzanne Woods, MD, said, “The percentage of women and men meeting the eligibility requirements for the exam did not differ. We stress this point because a concern about possible gender bias appears to have been the principal reason for this ... petition, and we wanted to offer immediate reassurance that no unintended bias has occurred.”

“We are carefully considering the requests and will release detailed data to hospitalists on the AAP’s [pediatric hospital medicine (PHM) electronic discussion board] ... and on the ABP’s website. We are conferring with ABP PHM subboard members as well as leaders from our volunteer community. We expect to provide a thoughtful response within the next 3 weeks,” Dr. Woods said in the Aug. 15 statement.
 

“Case-by-case” exceptions

The backstory is that, for better or worse depending on who you talk to, pediatric hospital medicine is becoming a board certified subspecialty. A fellowship will be required to sit for the exam after a few years, which is standard for subspecialties.

What’s generated concern is how the board is grandfathering current pediatric hospitalists into certification via a “practice pathway” until the fellowship requirement takes hold after 2023.

To qualify for the November test, hospitalists had to complete 4 years of full-time practice by June 30, 2019, which has been understood to mean 48 months of continual employment. At least 50% of that time had to be devoted to “professional activities ... related to the care of hospitalized children,” and at least 25% of that “devoted to direct patient care.” Assuming about 2,000 work hours per year, it translated to “450-500 hours” of direct patient care “per year over the most recent four years” to sit for the test, the board said.

“For individuals who have interrupted practice during the most recent four years for family leave or other such circumstances, an exception may be considered if there is substantial prior experience in pediatric hospital medicine. ... Such exceptions are made at the discretion of the ABP and will be considered on a case-by-case basis.” Specific criteria for exceptions were not spelled out.

In the end, there were more than a few surprises when denial letters went out in recent months, and scores of appeals have been filed. There’s “a lot of tension and a lot of confusion” about why some people with practice gaps during the 4 years were approved, but others were denied. There’s been “a lack of transparency on the ABP’s part,” said H. Barrett Fromme, MD, section chief of pediatric hospital medicine and a professor of pediatrics at the University of Chicago.
 

“The standard has to be reasonable”

There are concerns about the availability of fellowship slots and other issues, but the 4-year rule – instead of averaging clinical hours over 4 or 5 years, for instance – is the main sticking point. It’s a gender issue because “women take maternity; women move with their spouse; women take care of elders; women tend to be in these roles that require time off” more than men do, Dr. Fromme said.

Until the board releases its data, the gender breakdown of the denials and the degree to which practice gaps due to such issues led to them is unknown. There’s concern that women have been unfairly penalized.

The storm was set off on the discussion board this summer by stories from physicians such as Chandani DeZure, MD, a pediatric hospitalist currently working in the neonatal ICU at Stanford (Calif.) University. She was denied a seat at the table in November, appealed, and was denied again.

She was a full-time pediatric hospitalist at Children’s National Medical Center in Washington, from 2014, when she graduated residency, until Oct. 2018, when her husband, also a doctor, was offered a promising research position in California, and “we decided to take it,” Dr. DeZure said.

They moved to California with their young son in November. Dr. DeZure got her California medical license in 6 weeks, was hired by Stanford in January, and started her new postion in mid-April.

Because of the move, she worked only 3.5 years in the board’s 4 year practice window, but, as is common with young physicians, that time was spent in direct patient care, for a total of over 6,000 hours.

“How is that not good enough? How is a person that worked 500 hours with patients for 4 years” – for a total of 2,000 hours – “better qualified than someone who worked 100% for 3 and a half years? Nobody is saying there shouldn’t be a standard, but the standard has to be reasonable,” Dr. DeZure said.
 

“Illegal regardless of intent”

It’s situations like Dr. DeZure’s that led to the petition. One of demands is that ABP “revise the practice pathway criteria to be more inclusive of applicants with interrupted practice and varied clinical experience, to include clear-cut parameters rather than considering these applications on a closed-door ‘case-by-case basis...at the discretion of the ABP.’ ” Also, the petition asks the board to “clarify the appeals process and improve responsiveness to appeals and inquiries regarding denials.”

As ABP noted in its statement, however, the major demand is that the board “facilitate a timely analysis to determine if gender bias is present.” The petition noted that signers “do not suspect intentional bias on the part of the ABP; however, if gender bias is present it is unethical and potentially illegal regardless of intent.”

For now, the perception is that the board has “a hard 48-month rule” with not many exceptions; there are people who are “very concerned that, ‘Oh my gosh, I can’t have children for 4 years because I won’t be able to sit for the boards.’ No one should ever have to have that in their head,” Dr. Fromme said. At this point, it seems that 3 months off for maternity is being grandfathered in, but perhaps not 6 months for a second child; no one knows for sure.

Dr. DeZure, meanwhile, continues to study for the board exam, just in case.

Looking back over the past year, she said “I could have somehow picked up one shift a week moonlighting that would have kept me eligible, but the [board] didn’t respond to me” when contacted about her situation during the California move.

“The other option was for me was to live cross country from my husband with a small child,” she said.

Case

A 78-year-old woman with end-stage renal disease (ESRD) is hospitalized with cellulitis and is incidentally found to be in atrial fibrillation. She does not have a history of mitral stenosis, nor does she have a prosthetic valve. She does have a history of hypertension, diabetes, and prior stroke without residual deficits.

After counseling her about the risk of stroke associated with atrial fibrillation (AFib) she makes it clear she is interested in pharmacologic therapy to minimize her risk of stroke and asks what medication you would recommend for anticoagulation.

Brief overview of the issue

Anticoagulation for AFib is indicated for stroke prophylaxis in patients with an elevated risk of stroke. The CHA₂DS₂-VASc score is useful in calculating an individual patient’s risk of stroke and as a decision tool to determine who would benefit from anticoagulation, and it is recommended in the American Heart Association guidelines.¹

Low-risk patients (CHA₂DS₂-VASc score of 0 in men or 1 in women) should not be started on anticoagulation for stroke prophylaxis. For anyone with a risk factor, other than being female, anticoagulation is indicated and should be considered.

The guideline recommends anticoagulant therapy, not antiplatelet agents. For most of the recent past, this has meant a vitamin K antagonist (warfarin) or sometimes a low-molecular-weight heparin injected subcutaneously. Over the past decade, however, with the approval of multiple direct oral anticoagulants (DOACs), nonwarfarin oral anticoagulation has grown in popularity as the prophylactic medication of choice.²

While the data for patients with preserved renal function is robust, there is far less data to guide decision making for patients with end-stage renal disease.

Overview of the data

Until the introduction of DOACs, warfarin was the main agent used for stroke prophylaxis in patients with end-stage kidney disease and AFib. Professional guidelines favored warfarin for these patients who were mostly excluded from DOAC trials. Specialized conferences also looked at this issue.

The Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference, which reviewed chronic kidney disease and arrhythmias, noted that there were no randomized controlled trials that examined the efficacy and safety of anticoagulation in chronic kidney disease patients with estimated creatinine clearance less than 30 mL/min. They remarked that there was insufficient high-quality evidence to recommend warfarin for the prevention of stroke in patients with AFib and dialysis-dependent chronic kidney disease.

Since, according to other trials, DOACs had better safety profiles in other populations, the conference noted that lower-dose apixaban (2.5 mg orally twice daily) or rivaroxaban (15 mg daily) may be considered in this population until clinical safety data were available. Furthermore, the conference recommended that these patients be treated with a multidisciplinary approach in regards to anticoagulation and have an annual reevaluation of treatment goals, along with a risk-benefit assessment.³

Since the publication of the 2018 AHA guidelines and the guidance document that resulted from the KDIGO conference, additional research has been published comparing anticoagulation with a DOAC versus warfarin for AFib in patients with ESRD.

“Outcomes associated with apixaban use in patients with end-stage kidney disease and atrial fibrillation in the United States” was an observational, retrospective, cohort study that compared outcomes in dialysis patients who took warfarin for AFib with those who took apixaban.⁴ Patients’ data was taken from the U.S. Renal Data System database and were included in the final analysis if they had ESRD, a recent diagnosis of AFib or atrial flutter, and a new prescription for either warfarin or apixaban. Outcome measures were stroke or systemic embolism, major bleeding (critical site, transfusion, or death), gastrointestinal bleeding, intracranial bleeding, or death. Drug usage and compliance were assessed using Medicare Part D prescription information.

A total of 25,523 patients met the inclusion/exclusion criteria and had taken either warfarin (n = 23,172) or apixaban (n = 2,351). To account for selection bias in these cohorts, a subset of the warfarin patients was selected based on prognostic score matching. The prognostic score was calculated from the baseline characteristics (which included age, stroke history, diabetes, smoking, antiplatelet medication, liver disease, prior bleeding, and CHA₂DS₂-VASc score). Kaplan-Meier and Cox regression analysis were used to give hazard ratios and 95% confidence intervals for each outcome measure. Prespecified subgroup analyses were conducted to compare apixaban doses, where 44% were prescribed 5 mg b.i.d. and 56% were prescribed 2.5 mg b.i.d..

In the study, patients in the apixaban group had a significantly lower risk of major bleeding as compared with the warfarin group (HR, 0.72; 95% CI, 0.59-0.87; P less than .001) with overall high rates of major bleeding in both groups at 19.7 and 22.9 per 100 patient-years in the apixaban group and warfarin group, respectively. There was no difference in the rate of stroke/systemic embolism between patients receiving apixaban and warfarin (HR, 0.88; 95% CI, 0.69-1.12; P = .29). There was a nonsignificant trend toward decreased risk of GI bleeding in the apixaban group and no significant differences between the groups in the rates of intracranial bleeding. Apixaban was also associated with a nonsignificant trend toward lower risk of mortality (HR, 0.85; 95% CI, 0.71-1.01; P = .06).

Notably, censoring rates because of expired prescriptions or a 1-month gap between prescriptions were high in both groups and the majority of censoring occurred within the first 12 months. Additionally, in dose specific analyses, patients receiving the 5-mg, twice-daily dose were found to have statistically significant decreases in risk of stroke/systemic embolism (P = .035) and mortality (P = .005) as compared with the 2.5-mg, twice-daily dose without significant differences in GI or intracranial bleeding.

There are three ongoing, open-label, randomized, controlled trials examining anticoagulation for nonvalvular AFib in patients with ESRD on hemodialysis with two comparing apixaban to warfarin (or derivative) and the other warfarin versus no anticoagulation.⁵ All trials are in adult patients with documented AFib and CHA₂DS₂-VASc score of at least 2. AKADIA (Germany based) plans to enroll 222 patients and compares a vitamin K antagonist (INR goal, 2-3) with 2.5-mg b.i.d. apixaban patients with ESRD on hemodialysis for at least 3 months with primary outcome of major and clinically relevant nonmajor bleeding and secondary outcome of thromboembolic events, as well as apixaban levels pre- and post hemodialysis.

RENAL-AF (U.S. based) plans to enrolled 762 patients and compares 5-mg b.i.d. apixaban (with 2.5 mg for selected patients) with warfarin in people of chronic hemodialysis with primary outcome of days to first major or clinically relevant nonmajor bleeding event and secondary outcome of stroke, systemic embolism, mortality, adherence and plasma apixaban levels. AVKDIAL (France based) plans to enroll 855 patients and compares no anticoagulation with vitamin K antagonists in patients on hemodialysis for at least 1 month, with primary outcome of cumulative incidence of severe bleeding and thrombosis.

Application of the data to our original case

Our patient is Medicare age with ESRD and newly diagnosed nonvalvular AFib. Recent data suggests apixaban could be used for stroke prevention instead of the prior standard of care, warfarin. This approach is supported in the 2019 guidelines.¹

Patients with ESRD have an increased risk of bleeding and apixaban was shown to have less bleeding complications than warfarin in this analysis. However, only standard-dose apixaban was associated with a statistically significant lower risk of stroke/systemic embolism, major bleeding, and death. Reduced-dose apixaban had a lower risk of major bleeding but no difference for stroke/systemic embolism or death. Reduced-dose apixaban is used for patients who have two out of the following three criteria: aged at least 80 years, weight of at least 60 kg, and creatinine of at least 1.5 mg/dL. Therefore, many Medicare-age patients with ESRD would not be indicated for the dose of apixaban that was shown to improve the most important outcomes of stroke/SE and death.

It may still be beneficial to use apixaban in this patient since it appears to work as well as warfarin for stroke/systemic embolism prevention with less bleeding complications.

Bottom line

For patients who have decided to pursue an anticoagulation strategy for stroke prevention in AFib and have end-stage renal disease, either warfarin or apixaban are sensible options.

Key points

• According to 2019 American Heart Association guidelines, warfarin or apixaban are reasonable options for stroke prevention for patients who have end-stage renal disease and who plan for anticoagulation because of atrial fibrillation.
• Recent observational data suggests that apixaban may be safer than warfarin in this population.
• Several randomized, controlled trials are ongoing that may help determine the optimal agent to use in this setting.
• Until more definitive data is available, a reasonable approach is to discuss the risks and benefits of various treatment strategies with patients, and engage a multidisciplinary team (cardiologist, nephrologist, primary care provider, pharmacist) in the decision making process.

Quiz

Two days ago you admitted a 72-year-old woman with end-stage renal disease on dialysis who had developed new-onset atrial fibrillation causing a mild acute diastolic congestive heart failure exacerbation. Transthoracic ECG showed a preserved left ventricular ejection fraction and no significant valvular disease. After two sessions of dialysis in the hospital and initiation of a beta-blocker for control of her heart rate, she is stable and ready for discharge. Her discharge weight is 75 kg.

Which of the following recommendations should you make to this patient regarding anticoagulation for prevention of stroke and systemic embolism from atrial fibrillation?

A. Take warfarin with a international normalized ratio goal of 2.5.

B. Take apixaban 2.5 mg twice a day.

C. Take apixaban 5 mg twice a day.

D. Discuss the risks/benefits of various treatment approaches with the patient, and involve the hospital pharmacist as well as the patient’s nephrologist, cardiologist, and/or primary care provider in the decision making process to reach a consensus and to ensure a safe follow-up plan.

The best answer is D. While A, B, and C are all reasonable approaches based on the available data and current guidelines, the best approach is to involve the patient and the multidisciplinary team in the decision making process. When more clinical trial data becomes available in the future, the optimal approach to managing patients such as this one may become clearer, but until then it makes sense to take into account individual patient characteristics and patient preferences.

Case

A 78-year-old woman with end-stage renal disease (ESRD) is hospitalized with cellulitis and is incidentally found to be in atrial fibrillation. She does not have a history of mitral stenosis, nor does she have a prosthetic valve. She does have a history of hypertension, diabetes, and prior stroke without residual deficits.

After counseling her about the risk of stroke associated with atrial fibrillation (AFib) she makes it clear she is interested in pharmacologic therapy to minimize her risk of stroke and asks what medication you would recommend for anticoagulation.

Brief overview of the issue

Anticoagulation for AFib is indicated for stroke prophylaxis in patients with an elevated risk of stroke. The CHA₂DS₂-VASc score is useful in calculating an individual patient’s risk of stroke and as a decision tool to determine who would benefit from anticoagulation, and it is recommended in the American Heart Association guidelines.¹

Low-risk patients (CHA₂DS₂-VASc score of 0 in men or 1 in women) should not be started on anticoagulation for stroke prophylaxis. For anyone with a risk factor, other than being female, anticoagulation is indicated and should be considered.

The guideline recommends anticoagulant therapy, not antiplatelet agents. For most of the recent past, this has meant a vitamin K antagonist (warfarin) or sometimes a low-molecular-weight heparin injected subcutaneously. Over the past decade, however, with the approval of multiple direct oral anticoagulants (DOACs), nonwarfarin oral anticoagulation has grown in popularity as the prophylactic medication of choice.²

While the data for patients with preserved renal function is robust, there is far less data to guide decision making for patients with end-stage renal disease.

Overview of the data

Until the introduction of DOACs, warfarin was the main agent used for stroke prophylaxis in patients with end-stage kidney disease and AFib. Professional guidelines favored warfarin for these patients who were mostly excluded from DOAC trials. Specialized conferences also looked at this issue.

The Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference, which reviewed chronic kidney disease and arrhythmias, noted that there were no randomized controlled trials that examined the efficacy and safety of anticoagulation in chronic kidney disease patients with estimated creatinine clearance less than 30 mL/min. They remarked that there was insufficient high-quality evidence to recommend warfarin for the prevention of stroke in patients with AFib and dialysis-dependent chronic kidney disease.

Since, according to other trials, DOACs had better safety profiles in other populations, the conference noted that lower-dose apixaban (2.5 mg orally twice daily) or rivaroxaban (15 mg daily) may be considered in this population until clinical safety data were available. Furthermore, the conference recommended that these patients be treated with a multidisciplinary approach in regards to anticoagulation and have an annual reevaluation of treatment goals, along with a risk-benefit assessment.³

Since the publication of the 2018 AHA guidelines and the guidance document that resulted from the KDIGO conference, additional research has been published comparing anticoagulation with a DOAC versus warfarin for AFib in patients with ESRD.

“Outcomes associated with apixaban use in patients with end-stage kidney disease and atrial fibrillation in the United States” was an observational, retrospective, cohort study that compared outcomes in dialysis patients who took warfarin for AFib with those who took apixaban.⁴ Patients’ data was taken from the U.S. Renal Data System database and were included in the final analysis if they had ESRD, a recent diagnosis of AFib or atrial flutter, and a new prescription for either warfarin or apixaban. Outcome measures were stroke or systemic embolism, major bleeding (critical site, transfusion, or death), gastrointestinal bleeding, intracranial bleeding, or death. Drug usage and compliance were assessed using Medicare Part D prescription information.

A total of 25,523 patients met the inclusion/exclusion criteria and had taken either warfarin (n = 23,172) or apixaban (n = 2,351). To account for selection bias in these cohorts, a subset of the warfarin patients was selected based on prognostic score matching. The prognostic score was calculated from the baseline characteristics (which included age, stroke history, diabetes, smoking, antiplatelet medication, liver disease, prior bleeding, and CHA₂DS₂-VASc score). Kaplan-Meier and Cox regression analysis were used to give hazard ratios and 95% confidence intervals for each outcome measure. Prespecified subgroup analyses were conducted to compare apixaban doses, where 44% were prescribed 5 mg b.i.d. and 56% were prescribed 2.5 mg b.i.d..

In the study, patients in the apixaban group had a significantly lower risk of major bleeding as compared with the warfarin group (HR, 0.72; 95% CI, 0.59-0.87; P less than .001) with overall high rates of major bleeding in both groups at 19.7 and 22.9 per 100 patient-years in the apixaban group and warfarin group, respectively. There was no difference in the rate of stroke/systemic embolism between patients receiving apixaban and warfarin (HR, 0.88; 95% CI, 0.69-1.12; P = .29). There was a nonsignificant trend toward decreased risk of GI bleeding in the apixaban group and no significant differences between the groups in the rates of intracranial bleeding. Apixaban was also associated with a nonsignificant trend toward lower risk of mortality (HR, 0.85; 95% CI, 0.71-1.01; P = .06).

Notably, censoring rates because of expired prescriptions or a 1-month gap between prescriptions were high in both groups and the majority of censoring occurred within the first 12 months. Additionally, in dose specific analyses, patients receiving the 5-mg, twice-daily dose were found to have statistically significant decreases in risk of stroke/systemic embolism (P = .035) and mortality (P = .005) as compared with the 2.5-mg, twice-daily dose without significant differences in GI or intracranial bleeding.

RENAL-AF (U.S. based) plans to enrolled 762 patients and compares 5-mg b.i.d. apixaban (with 2.5 mg for selected patients) with warfarin in people of chronic hemodialysis with primary outcome of days to first major or clinically relevant nonmajor bleeding event and secondary outcome of stroke, systemic embolism, mortality, adherence and plasma apixaban levels.

Key points

• According to 2019 American Heart Association guidelines, warfarin or apixaban are reasonable options for stroke prevention for patients who have end-stage renal disease and who plan for anticoagulation because of atrial fibrillation.
• Recent observational data suggests that apixaban may be safer than warfarin in this population.
• Several randomized, controlled trials are ongoing that may help determine the optimal agent to use in this setting.
• Until more definitive data is available, a reasonable approach is to discuss the risks and benefits of various treatment strategies with patients, and engage a multidisciplinary team (cardiologist, nephrologist, primary care provider, pharmacist) in the decision making process.

Quiz

Two days ago you admitted a 72-year-old woman with end-stage renal disease on dialysis who had developed new-onset atrial fibrillation causing a mild acute diastolic congestive heart failure exacerbation. Transthoracic ECG showed a preserved left ventricular ejection fraction and no significant valvular disease. After two sessions of dialysis in the hospital and initiation of a beta-blocker for control of her heart rate, she is stable and ready for discharge. Her discharge weight is 75 kg.

Which of the following recommendations should you make to this patient regarding anticoagulation for prevention of stroke and systemic embolism from atrial fibrillation?

A. Take warfarin with a international normalized ratio goal of 2.5.

B. Take apixaban 2.5 mg twice a day.

C. Take apixaban 5 mg twice a day.

D. Discuss the risks/benefits of various treatment approaches with the patient, and involve the hospital pharmacist as well as the patient’s nephrologist, cardiologist, and/or primary care provider in the decision making process to reach a consensus and to ensure a safe follow-up plan.

The best answer is D. While A, B, and C are all reasonable approaches based on the available data and current guidelines, the best approach is to involve the patient and the multidisciplinary team in the decision making process. When more clinical trial data becomes available in the future, the optimal approach to managing patients such as this one may become clearer, but until then it makes sense to take into account individual patient characteristics and patient preferences.

John E. Parker, MD, was working at a West Virginia hospital in 2015 when a 31-year-old female patient was admitted with acute respiratory problems. A team of doctors ultimately suspected that her mysterious case of lipoid pneumonia might be related to vaping and weren’t sure they had seen anything like it before. They were intrigued enough to submit the case for presentation at the CHEST Annual Meeting that year (Chest. 2015;148:382A. doi: 10.1378/chest.2274860).

Now, almost 4 years later, federal officials have begun investigating a national outbreak of severe lung illnesses linked to vaping that has struck more than 150 patients in 16 states. In an interview, Dr. Parker, a professor of pulmonary critical care and sleep medicine at West Virginia University, Morgantown, described what happened.
 

Q: Can you describe what the patient’s symptoms were when she arrived?

We would view them as classic for what is getting to be called vaping-associated lung disease. She was very, very short of breath and had a cough, and we were, of course, very worried that she might have pneumonia or some other acute respiratory illness. And then she was so sick she needed to be intubated.

Q: What happens next in cases like this?

We look for things like a [hemorrhage] or an active infection. And then for lipid-containing macrophages. And then we usually start some antibiotics [and a] low-dose steroid and then support the patient with a ventilator and oxygen and nutrition. And then just kind of wait and see if any other cultures come back to prove anything different than what you might be thinking.

Early on, we just felt like it was an unusual case and may not be a common viral or bacterial infection.
 

Q: How did you figure out the cause of her lipoid pneumonia was e-cigarettes?

It’s a diagnosis of exclusion. We excluded other [options], and it became the most likely cause.

We were convinced enough that the case was submitted for [presentation at the CHEST annual meeting] and was accepted.
 

Q: Once you figured out the cause could be e-cigarettes, did you contact the Centers for Disease Control and Prevention or the Food and Drug Administration or any other regulatory agency to tell them about this?

We did not. We felt at the time that putting it in the medical literature was appropriate. And if other case reports from other parts of the country came forward, then we’d have more of a clustering of findings that might then warrant research agencies [getting a] better understanding [about] the cause of the disease.

Q: Which federal agency would you report it to, if you did?

In 2015, the FDA, of course, was still regulating cigarettes, but I don’t think the government had yet decided who would regulate vaping products. So I’m sure it was unclear who we should call.

Q: So did you or your team think this was a one-off event when you witnessed it?

We really felt that it wasn’t going to be a one-off event and that it was what we usually called in public health a “sentinel” health event … that it was an example of a respiratory illness that can be caused by this exposure and that it probably wasn’t the first case ever seen nor would it be the last.

Q: Was it the first case that you had seen at your institution?

To our knowledge it was our first case, but we are humble enough clinicians to realize we may have missed some other cases that we interpreted [as] viral pneumonia or bacterial pneumonia.

Q: Have you seen more cases since then?

I know we’ve seen a case [of alveolar hemorrhage syndrome] that we published, and in polling some colleagues, we think we’ve probably also seen [cases of] cryptogenic organizing pneumonia as well as lipoid pneumonia and acute eosinophilic pneumonia. Yeah, we’ve certainly seen at least probably four forms of lung disease from vaping.

Q: If your team was seeing this back in 2015, is it possible that it’s been happening in the four years since then and people just don’t know about it?

I really have every reason to think we were not the first ones to see it, by any means.

And I don’t think we were even the first ones to report it. I think that there were some clusters in Wisconsin and some other places in the United States. I also know that the Japanese have been very interested. They’ve probably got four or five papers at least in the medical literature about vaping-related lung injury.
 

Q: Do you have a theory of what might be causing the lipoid pneumonia cases? Do you think there may be certain chemicals that are irritants?

We need a strong multidisciplinary team to understand the real etiology and cause of lung injury from inhalation. I think it could be any number of components in the mixtures. Lungs don’t like oil, in general, and probably the most specific agent that’s been studied recently is diacetyl, which was studied in popcorn-flavoring lung disease.

Q: Have these kinds of cases changed the way you approach patients?

Yeah, we search very carefully for a history of vaping. … I think it’s quite important to understand if they might be using inhaled agents or vaping that might present new toxicities to the lung.

Q: Will these illnesses have long-term health effects?

An inhalational injury may cause an acute lung injury that’s life-threatening and that someone may survive from and have no long-term sequelae [condition]. But there also is the possibility that long-term [e-cigarette] use may cause more insidious or chronic diseases from which there may not be a full recovery.

Treatment with the immune checkpoint inhibitor (ICI) pembrolizumab can induce lipodystrophy with severe metabolic complications, according to a case study.

A 47-year-old woman received pembrolizumab to treat metastatic melanoma and developed immune-related generalized acquired lipodystrophy. The condition has persisted 12 months after she stopped taking pembrolizumab.

Julie Delyon, MD, PhD, of Saint-Louis Hospital in Paris, and colleagues described this case in the British Journal of Dermatology.

The patient was diagnosed with BRAF-mutated, stage IV melanoma with bone and lymph node metastases. She received pembrolizumab at 2 mg/kg every 3 weeks as first-line treatment. She achieved a complete response and was still in remission at last follow-up.

The patient was obese at baseline, with a body mass index of 40 kg/m², but she did not have diabetes, hepatic steatosis, or dyslipidemia.

Within 2 months of starting pembrolizumab, the patient observed “some major changes to her physical appearance,” according to Dr. Delyon and colleagues. At 10 months, the patient had severe lipodystrophy.

The patient experienced a change in fat distribution – namely, severe peripheral lipoatrophy and an accumulation of trunk fat. Imaging revealed a decrease in subcutaneous adipose tissue, which contrasted with an increase in visceral fat observed from baseline.

The patient also developed “moderate hirsutism, facial and limb atrophy, and prominent forearm and leg muscles and veins,” according to the authors. She had impaired glucose tolerance with insulin resistance, reduced concentrations of leptin and adiponectin, hypertriglyceridemia, a low level of HDL cholesterol, and hepatic steatosis.

Analyses of subcutaneous fat revealed adipose tissue atrophy with edema, lipophages, and CD3+/CD4+ T-cell infiltration of the fat and vessel walls. This suggested that the lipodystrophy had an autoimmune origin, according to the authors.

The patient had no family history of autoimmune disease or lipodystrophy. She tested negative for mutations in 23 genes associated with generalized lipodystrophy.

The patient also tested negative for HIV, antinuclear antibodies, native anti-DNA, and anti-insulin receptor antibodies. There were no signs of panniculitis, and the authors noted that “there were no arguments in favor of hyperthyroidism, Cushing syndrome, or acromegaly.”

In an attempt to reverse the lipodystrophy, the researchers stopped pembrolizumab treatment. The patient was treated for diabetes and hypertriglyceridemia as well. She could not receive corticosteroids because of the risk of severe metabolic complications, and she didn’t receive metreleptin because it wasn’t available. The patient still had lipodystrophy 12 months after stopping pembrolizumab.

Dr. Delyon and colleagues wrote that this case suggests pembrolizumab, and perhaps other anti–programmed death 1 therapies, may cause lipodystrophy with severe metabolic complications. “The long-term side effects of such metabolic adverse events, although rare, are unknown and will probably become a topic of utmost importance, considering the increasing rate of remission following ICIs and their use in the adjuvant setting.”

Two coauthors reported relationships with Merck, which markets pembrolizumab as Keytruda. The authors also reported relationships with Bristol-Myers Squibb, Pierre Fabre, Takeda, Innate Pharma, LEO Pharma, Roche, GlaxoSmithKline, Novartis, and Amgen.

Q2. Correct Answer: A  
 
Rationale:  
In a patient with chronic pancreatitis and a pancreatic mass, the most likely etiology is adenocarcinoma. This patient has radiologically resectable pancreas cancer. There is no evidence of lymphadenopathy or vascular invasion. Performing an ERCP with stent placement to relieve biliary obstruction has not been shown to be of benefit in patients with a resectable pancreatic mass. In fact, surgical outcomes are worse if a stent is placed in the bile duct. Surgical consultation should be obtained and the patient should undergo pancreaticoduodenectomy. EUS is sometimes done, but most cases of resectable disease should go straight to surgery.

Risk factors for gallstone formation include increased age, female gender, pregnancy, dyslipidemia, diabetes, obesity and rapid weight loss - especially after gastric bypass surgery. Medications such as hormone replacement therapies/ oral contraceptive agents, fibrates, somatostatin analogues also increase gallstone risk. Currently, there is evidence suggesting potential benefit of prophylactic cholecystectomy during Roux-en-Y gastric bypass, given the potential risk of gallstone formation with rapid weight loss following surgery. However, there is also data from randomized controlled trials that the use of ursodeoxycholic acid following surgery may help reduce risk of gallstone formation for this group of patients.

Adding local treatment to systemic therapy may extend survival among certain patients with oligometastatic non–small cell lung cancer (NSCLC), according to a retrospective look at more than 34,000 patients.

Surgical resection provided the greatest survival benefit, followed by external beam radiotherapy or thermal ablation (EBRT/TA), reported lead author Johannes Uhlig, MD, of University Medical Center Göttingen (Germany) and colleagues.

NSCLC patients with five or fewer metastatic sites (oligometastatic disease) are thought to achieve better outcomes than patients with more widely disseminated disease, the investigators noted in JAMA Network Open, but the benefit of local therapy for this population is unclear.

“A recent randomized, prospective study of 74 patients with oligometastatic NSCLC identified superior progression-free survival with local control after hypofractionated radiotherapy or surgical resection and radiotherapy compared with systemic therapy alone, suggesting an important application of local treatment options for patients with metastatic disease,” the investigators wrote.

To build on these findings, the investigators retrospectively evaluated 34,887 patients with stage IV NSCLC who had up to one distant metastatic lesion in the liver, lung, brain, or bone, as documented in the National Cancer Database. Treatment groups were divided into patients who received systemic therapy alone, surgical resection plus systemic therapy, or EBRT/TA plus systemic therapy. Multivariable Cox proportional hazards models were used to compare overall survival among the three groups.

Including a median follow-up of 39.4 months, data analysis showed that patients who underwent surgery and systemic therapy fared the best. Adding surgery reduced mortality risk by 38% and 41%, compared with EBRT/TA plus systemic therapy and systemic therapy alone, respectively (P less than .001 for both). Compared with systemic therapy alone, adding EBRT/TA reduced mortality risk by 5% (P = .002).

The impact of EBRT/TA varied among subgroups. For those with squamous cell carcinoma who had limited nodal disease, adding EBRT/TA resulted in a clear benefit, reducing mortality risk by 32% (P less than .001). Compared with systemic therapy alone, this benefit translated to higher survival rates for up to 3 years. Conversely, adding EBRT/TA increased risk of death by 39% among patients with extended local and distant adenocarcinoma (P less than .001). In this subgroup, survival rates over the next 3 years were higher among patients treated with systemic therapy alone.

“The present study supports a combined approach of local therapy in addition to systemic treatment for select patients with oligometastatic NSCLC,” the investigators concluded.

The study was funded by the U.S. Department of Defense. The investigators disclosed additional relationships with Bayer, AstraZeneca, Bristol-Myers Squibb, and others.

Showing cancer patients receiving chemotherapy short videos about their treatments has the potential to improve their understanding about the treatments they are receiving, new research in Cancer has shown.

Researchers showed 50 patients at an underserved hospital six 1-minute videos focused on important terms related to their chemotherapy treatments and found that the videos helped them better understand what those key terms mean. Before viewing the videos, 15 of 20 terms were misunderstood by more than one third of patients, with 98% unable to define “maintenance,” 74% unable to define “cancer,” and 58% unable to define “chemotherapy.” Six pilot educational videos describing a narrowed down list of six terms were created, and patient understanding of all six terms improved by at least 20% after watching the videos. The six terms defined in the videos were “palliative chemotherapy,” “curative,” “cancer,” “blood count,” “risk of infection,” and “chemotherapy.”

“Although a current concern is that precision medicines will not be understood due to genetic illiteracy and misunderstandings about the immune system, it is important to remember that the terminology used to describe chemotherapy, the backbone of many cancer treatments, may also be incomprehensible to some patients,” Rebecca Pentz, PhD, of Emory University, Atlanta, and colleagues wrote.

“Our video pilot suggests that multimedia can help patients understand chemotherapy terminology,” Dr. Pentz and colleagues said. “For each term, there was at least a 20% increase in patient understanding after watching the video. None of the patients could define palliative chemotherapy before watching the video, but 72% were able to provide a definition afterward.”

Researchers noted that the term most understood after the video was curative treatment (patients being able to define the phrase grew from 34% to 88%).

“Our study establishes that basic chemotherapy terminology is widely misunderstood by an underserved population, but that video-based education can significantly increase patient understanding,” the investigators concluded, but noted the research was limited by the small number of videos as well as the single underserved hospital, which may limit the generalizablility of the study.

Dr. Pentz and colleagues added that “education of physicians about the severe patient lack of understanding of basic cancer terminology and methods to improve understanding would be most helpful.”
