Brad Kahl, MD, shares results from non-Hodgkin lymphoma clinical trials that were presented at the 2021 American Society of Hematology (ASH) Annual Meeting. 

Dr Kahl looks first at a frontline study examining a new combination therapy. The POLARIX study compared polatuzumab vedotin plus rituximab, cyclophosphamide, doxorubicin, and prednisone (Pola-R-CHP) with standard of care in patients with untreated diffuse large B-cell lymphoma (DLBCL). Pola-R-CHP demonstrated significant improvement in progression-free survival. 

In relapsed/refractory non-Hodgkin lymphoma, Dr Kahl highlights several studies in chimeric antigen receptor (CAR) T-cell therapy. He starts with a primary analysis of the ZUMA-7 trial, in which axicabtagene ciloleucel (axi-cel) demonstrated improved survival compared with standard of care in patients with relapsed/refractory DLBCL. 

Next, he reports on the TRANSFORM study, which compared lisocabtagene maraleucel (liso-cel) with standard of care in the second-line setting for patients with high-risk relapsed/refractory DLBCL. Liso-cel demonstrated favorable outcomes, with improved event-free survival and no new safety concerns. 

The third CAR T-cell study he discusses is an updated analysis from ZUMA-5 that shows longer-term data for axi-cel in patients with relapsed/refractory follicular lymphoma or marginal zone lymphoma. Consistent with the primary analysis, this study demonstrated positive survival and safety outcomes in both groups. 

Finally, Dr Kahl examines a phase 1/2 study of mosunetuzumab monotherapy for patients with relapsed/refractory follicular lymphoma who have received at least two lines of therapy. The study demonstrated improved response rates and favorable safety results.

The volume of prescription opioids dispensed at retail pharmacies in the United States dropped by 21% in recent years amid efforts to reduce unnecessary use of the painkillers, but the rate of decline varied greatly among types of patients and by type of clinician, a study found.

In a brief report published by Annals of Internal Medicine, researchers from the nonprofit RAND Corp reported an analysis of opioid prescriptions from two periods, 2008-2009 and 2017-2018.

The researchers sought to assess total opioid use rather than simply track the number of pills dispensed. So they used days’ supply and total daily dose to calculate per capita morphine milligram equivalents (MME) for opioid prescriptions, write Bradley D. Stein, MD, PhD, MPH, the study’s lead author and a senior physician researcher at RAND Corp, and his coauthors in their paper.

For the study, the researchers used data from the consulting firm IQVIA, which they say covers about 90% of U.S. prescriptions. Total opioid volume per capita by prescriptions filled in retail pharmacies decreased from 951.4 MME in 2008-2009 to 749.3 MME in 2017-2018, Dr. Stein’s group found.

(In 2020, IQVIA separately said that prescription opioid use per adult in this country rose from an average of 16 pills, or 134 MMEs, in 1992 to a peak of about 55 pills a person, or 790 MMEs, in 2011. By 2019, opioid use per adult had declined to 29 pills and 366 MMEs per capita.)

The RAND report found substantial variation in opioid volume by type of insurance, including a 41.5% decline (636.5 MME to 372.6 MME) among people covered by commercial health plans. That exceeded the 27.7% drop seen for people enrolled in Medicaid (646.8 MME to 467.7 MME). The decline was smaller (17.5%; 2,780.2 MME to 2,294.2 MME) for those on Medicare, who as a group used the most opioids.

‘Almost functions as a Rorschach test’

The causes of the decline are easy to guess, although definitive conclusions are impossible, Dr. Stein told this news organization.

Significant work has been done in recent years to change attitudes about opioid prescriptions by physicians, researchers, and lawmakers. Aggressive promotion of prescription painkillers, particularly Purdue Pharma’s OxyContin, in the 1990s, is widely cited as the triggering event for the national opioid crisis.

In response, states created databases known as prescription drug monitoring programs. The Centers for Disease Control and Prevention in 2016 issued guidelines intended to curb unnecessary use of opioids. The guidelines noted that other medicines could treat chronic pain without raising the risk of addiction. The Choosing Wisely campaign, run by a foundation of the American Board of Internal Medicine, also offered recommendations about limiting use of opioids. And insurers have restricted access to opioids through the prior authorization process. As a result, researchers will make their own guesses at the causes of the decline in opioid prescriptions, based on their own experiences and research interests, Dr. Stein said.

“It almost functions as a Rorschach test,” he said.

Dr. Stein’s group also looked at trends among medical specialties. They found the largest reduction between 2008-2009 and 2017-2018 among emergency physicians (70.5% drop from 99,254.5 MME to 29,234.3 MME), psychiatrists (67.2% drop from 50,464.3 MME to 16,533.0 MME) and oncologists (59.5% drop from 51,731.2 MME to 20,941.4).

Among surgeons, the RAND researchers found a drop of 49.3% from 220,764.6 to 111,904.4. Among dentists, they found a drop of 41.3% from 22,345.3 to 13,126.1.

Among pain specialists, they found a drop of 15.4% from 1,020,808.4 MME to 863,140.7 MME.

Among adult primary care clinicians, Dr. Stein and his colleagues found a drop of 40% from 651,489.4 MME in 2008-2009 to 390,841.0 MME in 2017-2018.

However, one of the groups tracked in the study increased the volume of opioid prescriptions written: advanced practice providers, among whom scripts for the drugs rose 22.7%, from 112,873.9 MME to 138,459.3 MME.

Dr. Stein said he suspects that this gain reflects a change in the nature of the practice of primary care, with nurse practitioners and physician assistants taking more active roles in treatment of patients. Some of the reduction seen among primary care clinicians who treat adults may reflect a shift in which medical personnel in a practice write the opioid prescriptions.

Still, the trends in general seen by Dr. Stein and coauthors are encouraging, even if further study of these patterns is needed, he said.

“This is one of those papers that I think potentially raises as many questions as it provides answers for,” he said.

What’s missing

Maya Hambright, MD, a family medicine physician in New York’s Hudson Valley, who has been working mainly in addiction in response to the opioid overdose crisis, observed that the drop in total prescribed volume of prescription painkillers does not necessarily translate into a reduction in use of opioids

“No one is taking fewer opioids,” Dr. Hambright told this news organization. “I can say that comfortably. They are just getting them from other sources.”

CDC data support Dr. Hambright’s view.

An estimated 100,306 people in the United States died of a drug overdose in the 12 months that ended in April 2021, an increase of 28.5% from the 78,056 deaths during the same period the year before, according to the CDC.

Dr. Hambright said more physicians need to be involved in prescribing medication-assisted treatment (MAT).

The federal government has in the past year loosened restrictions on a requirement, known as an X waiver. Certain clinicians have been exempted from training requirements, as explained in the frequently asked questions page on the Substance Abuse and Mental Health Services Administration website.

SAMHSA says legislation is required to eliminate the waiver. As of Dec. 30, 2021, more than half of the members of the U.S. House of Representatives were listed as sponsors of the Mainstreaming Addiction Treatment (MAT) Act (HR 1384), which would end the need for X waivers. The bill has the backing of 187 Democrats and 43 Republicans.

At this time, too many physicians shy away from offering MAT, Dr. Hambright said.

“People are still scared of it,” she said. “People don’t want to deal with addicts.”

But Dr. Hambright said it’s well worth the initial time invested in having the needed conversations with patients about MAT.

“Afterwards, it’s so straightforward. People feel better. They’re healthier. It’s amazing,” she said. “You’re changing lives.”

The research was supported by grants from the National Institutes of Health. Dr. Stein and coauthors reported no relevant financial relationships.

The Centers for Disease Control and Prevention’s recently updated guidance on isolating and testing were tied to the public’s increased interest in testing, Director Rochelle Walenksy, MD, said during a White House briefing Jan. 5.

Health officials recently shortened the recommended COVID-19 isolation and quarantine period from 10 days to 5, creating confusion amid an outbreak of the highly transmissible Omicron variant, which now accounts for 95% of cases in the United States.

Then, in slightly updated guidance, the CDC recommended using an at-home antigen test after 5 days of isolation if possible, even though these tests having aren’t as sensitive to the Omicron variant, according to the FDA.

“After we released our recs early last week, it became very clear people were interested in using the rapid test, though not authorized for this purpose after the end of their isolation period,” Dr. Walensky said. “We then provided guidance on how they should be used.”

“If that test is negative, people really do need to understand they must continue to wear their mask for those 5 days,” Dr. Walensky said.

But for many, the CDC guidelines are murky and seem to always change.

“Nearly 2 years into this pandemic, with Omicron cases surging across the country, the American people should be able to count on the Centers for Disease Control and Prevention for timely, accurate, clear guidance to protect themselves, their loved ones, and their communities,” American Medical Association president Gerald Harmon, MD, said in a statement. “Instead, the new recommendations on quarantine and isolation are not only confusing, but are risking further spread of the virus.”

About 31% of people remain infectious 5 days after a positive COVID-19 test, Dr. Harmon said, quoting the CDC’s own rationale for changing its guidance.

“With hundreds of thousands of new cases daily and more than a million positive reported cases on January 3, tens of thousands – potentially hundreds of thousands of people – could return to work and school infectious if they follow the CDC’s new guidance on ending isolation after 5 days without a negative test,” he said. “Physicians are concerned that these recommendations put our patients at risk and could further overwhelm our health care system.”

Instead, Dr. Harmon said a negative test should be required for ending isolation.

“Reemerging without knowing one’s status unnecessarily risks further transmission of the virus,” he said.

Meanwhile, also during the White House briefing, officials said that early data continue to show that Omicron infections are less severe than those from other variants, but skyrocketing cases will still put a strain on the health care system.

“The big caveat is we should not be complacent,” presidential Chief Medical Adviser Anthony Fauci, MD, said a White House briefing Jan. 5.

He added that Omicron “could still stress our hospital system because a certain proportion of a large volume of cases, no matter what, are going to be severe.”

Cases continue to increase greatly. This week’s 7-day daily average of infections is 491,700 -- an increase of 98% over last week, Dr. Walensky said. Hospitalizations, while lagging behind case numbers, are still rising significantly: The daily average is 14,800 admissions, up 63% from last week. Daily deaths this week are 1,200, an increase of only 5%.

Dr. Walensky continues to encourage vaccinations, boosters, and other precautions.

“Vaccines and boosters are protecting people from the severe and tragic outcomes that can occur from COVID-19 infection,” she said. “Get vaccinated and get boosted if eligible, wear a mask, stay home when you’re sick, and take a test if you have symptoms or are looking for greater reassurance before you gather with others.”

The Centers for Disease Control and Prevention’s recently updated guidance on isolating and testing were tied to the public’s increased interest in testing, Director Rochelle Walenksy, MD, said during a White House briefing Jan. 5.

Health officials recently shortened the recommended COVID-19 isolation and quarantine period from 10 days to 5, creating confusion amid an outbreak of the highly transmissible Omicron variant, which now accounts for 95% of cases in the United States.

Then, in slightly updated guidance, the CDC recommended using an at-home antigen test after 5 days of isolation if possible, even though these tests having aren’t as sensitive to the Omicron variant, according to the FDA.

“After we released our recs early last week, it became very clear people were interested in using the rapid test, though not authorized for this purpose after the end of their isolation period,” Dr. Walensky said. “We then provided guidance on how they should be used.”

“If that test is negative, people really do need to understand they must continue to wear their mask for those 5 days,” Dr. Walensky said.

But for many, the CDC guidelines are murky and seem to always change.

“Nearly 2 years into this pandemic, with Omicron cases surging across the country, the American people should be able to count on the Centers for Disease Control and Prevention for timely, accurate, clear guidance to protect themselves, their loved ones, and their communities,” American Medical Association president Gerald Harmon, MD, said in a statement. “Instead, the new recommendations on quarantine and isolation are not only confusing, but are risking further spread of the virus.”

About 31% of people remain infectious 5 days after a positive COVID-19 test, Dr. Harmon said, quoting the CDC’s own rationale for changing its guidance.

“With hundreds of thousands of new cases daily and more than a million positive reported cases on January 3, tens of thousands – potentially hundreds of thousands of people – could return to work and school infectious if they follow the CDC’s new guidance on ending isolation after 5 days without a negative test,” he said. “Physicians are concerned that these recommendations put our patients at risk and could further overwhelm our health care system.”

Instead, Dr. Harmon said a negative test should be required for ending isolation.

“Reemerging without knowing one’s status unnecessarily risks further transmission of the virus,” he said.

Meanwhile, also during the White House briefing, officials said that early data continue to show that Omicron infections are less severe than those from other variants, but skyrocketing cases will still put a strain on the health care system.

“The big caveat is we should not be complacent,” presidential Chief Medical Adviser Anthony Fauci, MD, said a White House briefing Jan. 5.

He added that Omicron “could still stress our hospital system because a certain proportion of a large volume of cases, no matter what, are going to be severe.”

Cases continue to increase greatly. This week’s 7-day daily average of infections is 491,700 -- an increase of 98% over last week, Dr. Walensky said. Hospitalizations, while lagging behind case numbers, are still rising significantly: The daily average is 14,800 admissions, up 63% from last week. Daily deaths this week are 1,200, an increase of only 5%.

Dr. Walensky continues to encourage vaccinations, boosters, and other precautions.

“Vaccines and boosters are protecting people from the severe and tragic outcomes that can occur from COVID-19 infection,” she said. “Get vaccinated and get boosted if eligible, wear a mask, stay home when you’re sick, and take a test if you have symptoms or are looking for greater reassurance before you gather with others.”

Updated guidelines from the American Academy of Neurology advise against prescribing opioids for painful diabetic neuropathy – but note that several other oral and topical therapies may help ease pain.

Painful diabetic neuropathy is very common and can greatly affect an individual’s quality of life, guideline author Brian Callaghan, MD, University of Michigan, Ann Arbor, noted in a news release.

“This guideline aims to help neurologists and other doctors provide the highest quality patient care based on the latest evidence,” Dr. Callaghan said.

The recommendations update the 2011 AAN guideline on the treatment of painful diabetic neuropathy. The new guidance was published online Dec. 27, 2021, in Neurology and has been endorsed by the American Association of Neuromuscular & Electrodiagnostic Medicine.
 

Multiple options

To update the guideline, an expert panel reviewed data from more than 100 randomized controlled trials published from January 2008 to April 2020.

The panel noted that more than 16% of individuals with diabetes experience painful diabetic neuropathy, but it often goes unrecognized and untreated. The guideline recommends clinicians assess patients with diabetes for peripheral neuropathic pain and its effect on their function and quality of life.

Before prescribing treatment, health providers should determine if the patient also has mood or sleep problems as both can influence pain perception.

The guideline recommends offering one of four classes of oral medications found to be effective for neuropathic pain: tricyclic antidepressants such as amitriptyline, nortriptyline, or imipramine; serotonin norepinephrine reuptake inhibitors such as duloxetine, venlafaxine, or desvenlafaxine; gabapentinoids such as gabapentin or pregabalin; and/or sodium channel blockers such as carbamazepine, oxcarbazepine, lamotrigine, or lacosamide.

All four classes of medications have “comparable effect sizes just above or just below our cutoff for a medium effect size” (standardized median difference, 0.5), the panel noted.

In addition, “new studies on sodium channel blockers published since the last guideline have resulted in these drugs now being recommended and considered as effective at providing pain relief as the other drug classes recommended in this guideline,” said Dr. Callaghan.

When an initial medication fails to provide meaningful improvement in pain, or produces significant side effects, a trial of another medication from a different class is recommended.
 

Pain reduction, not elimination

Opioids are not recommended for painful diabetic neuropathy. Not only do they come with risks, there is also no strong evidence they are effective for painful diabetic neuropathy in the long term, the panel wrote. Tramadol and tapentadol are also not recommended for the treatment of painful diabetic neuropathy.

“Current evidence suggests that the risks of the use of opioids for painful diabetic neuropathy therapy outweigh the benefits, so they should not be prescribed,” Dr. Callaghan said.

For patients interested in trying topical, nontraditional, or nondrug interventions to reduce pain, the guideline recommends a number of options including capsaicin, glyceryl trinitrate spray, and Citrullus colocynthis. Ginkgo biloba, exercise, mindfulness, cognitive-behavioral therapy, and tai chi are also suggested.

“It is important to note that the recommended drugs and topical treatments in this guideline may not eliminate pain, but they have been shown to reduce pain,” Dr. Callaghan said. “The good news is there are many treatment options for painful diabetic neuropathy, so a treatment plan can be tailored specifically to each person living with this condition.”

Along with the updated guideline, the AAN has also published a new Polyneuropathy Quality Measurement Set to assist neurologists and other health care providers in treating patients with painful diabetic neuropathy.

The updated guideline was developed with financial support from the AAN.

Patients with chronic obstructive pulmonary disease (COPD) who are both frail and who have poor lung function or dyspnea are at especially high risk of disability within 3 to 5 years as well as all-cause mortality years later, a prospective cohort study of community-dwelling adults has shown.

“Frailty, a widely recognized geriatric syndrome characterized by multidimensional functional decline in bio-psycho-social factors, is associated with functional disability and mortality,” senior author Tze Pin Ng, MD, National University of Singapore, and colleagues explain.“Our results ... suggest that beyond traditional prognostic markers such as FEV1% (forced expiratory volume in 1 second) and dyspnea, the physical frailty phenotype provides additional useful prognostic information on future risks of disability and mortality,” the authors suggest.

The study was published online Dec. 12 in the journal CHEST^®.

SLAS-1 and SLAS-2

Data from the Singapore Longitudinal Ageing Study (SLAS-1) and SLAS-2 were collected and analyzed. SLAS-1 recruited 2,804 participants 55 years of age and older from Sept. 2003 through Dec. 2004, while SLAS-2 recruited 3,270 participants of the same age between March 2009 and June 2013. “Follow-up visits and assessments were conducted approximately 3-5 years apart,” the investigators noted.

Mortality was determined at a mean of 9.5 years of follow-up for SLAS-1 participants and a mean of 6.5 years’ follow-up for SLAS-2 participants. A total of 4,627 participants were eventually included in the analysis, of whom 1,162 patients had COPD and 3,465 patients did not. COPD was classified as mild if FEV1% was greater than or equal to 80%; moderate if FEV1% was greater than or equal to 50% to less than 80%, and severe if FEV1% was less than 50%.

Frailty in turn was based on five clinical criteria, including weakness, slowness, low physical activity, exhaustion, and shrinking. Participants were classified as frail if they met three or more of these criteria and prefrail if they met one or two criteria.

Adverse health outcomes were judged on the basis of instrumental or basic activities of daily living (IADL/ADL), while disability was judged by self-reported difficulties in or requiring assistance with at least one IADL or ADL.
 

Frail or prefrail

Almost half of the participants were frail or prefrail, as the authors reported, while 25% had COPD. Among the participants with COPD, 30% had moderate to severe COPD, 6.4% had dyspnea, and almost half had prefrailty, while approximately 7% were classified as frail.

This percentage was 86% higher than it was for participants without COPD, among whom just 3.2% were assessed as frail, at an odds ratio of 1.86 (95% CI, 1.35-2.56). Further adjustments for possible confounders reduced the gap between frail COPD and frail non-COPD participants, but frailty remained significantly associated with COPD, at an OR of 1.61 (95% CI, 1.15-2.26), the investigators note.

Furthermore, compared to those without COPD, a diagnosis of COPD without and with dyspnea was associated with a 1.5- and 4.2-fold increase in prevalent frailty (95% CI, 1.04-2.08; 1.84-9.19), respectively, although not with prefrailty. Again, adjusting for multiple confounders, FEV1%, dyspnea, and both prefrailty and frailty were associated with an approximately twofold higher prevalence of IADL/ADL disability, while the prevalence of IADL/ADL disability for participants with COPD was approximately fourfold higher in those with co-occurring FEV1% less than 80% with either prefrailty, frailty, or dyspnea.

Furthermore, the presence of prefrailty or frailty in combination with a lower FEV1% or dyspnea was associated with a 3.7- to 3.8-fold increased risk of having an IADL or ADL disability.
 

Frailty and mortality

Some 1,116 participants with COPD were followed for a mean of 2,981 days for mortality outcomes. Both FEV1% less than 50% and the presence of prefrailty and frailty almost doubled the risk of mortality, at an adjusted hazard ratio of 1.8 (95% CI, 1.24-2.68) compared to patients with an FEV1% greater than or equal to 80%. In combination with either FEV1% less than 80% or prefrailty/frailty, dyspnea almost more than doubled the risk of mortality, at an HR of 2.4 for both combinations.

“However, the mortality risk of participants with COPD was highest among those with FEV1% less than 80% and prefrailty/frailty,” the authors note, more than tripling mortality risk at an adjusted HR of 3.25 (95% CI, 1.97-5.36). Interestingly, FEV1 less than 80% and prefrailty/frailty – both alone and in combination – were also associated with a twofold to fourfold increased risk of IADL or ADL disability in participants without COPD but were less strongly associated with mortality.

Researchers then went on to create a summary risk score containing all relevant variables with values ranging from 0 to 5. The highest risk category of 3 to 5 was associated with a 7- to 8.5-fold increased risk for IADL and ADL disability and mortality among participants with COPD, and that risk remained high after adjusting for multiple confounders.

Interestingly, frailty did not significantly predict mortality in women, while dyspnea did not significantly predict mortality in men. “Recognition and assessment of physical frailty in addition to FEV1% and dyspnea would allow for more accurate identification and targeted treatment of COPD at risk of future adverse outcomes,” the authors suggest.
 

Frailty scoring system

Asked to comment on the study, Sachin Gupta, MD, a pulmonologist and critical care specialist at Alameda Health System in Oakland, Calif., noted that the current study adds to the body of literature that outcomes in patients with COPD depend as much on objectively measured variables as on qualitative measures. “By applying a frailty scoring system, these researchers were able to categorize frailty and study its impact on patient characteristics and outcomes,” he told this news organization in an email.

The summary risk assessment tool developed and assessed is familiar: It carries parallels to the widely utilized BODE Index, replacing body mass index and 6-minute walk distance with the frailty scale, he added. “Findings from this study support the idea that what meets the eye in face-to-face visits – frailty – can be codified and be part of a tool that is predictive of outcomes,” Dr. Gupta underscored.

The authors had no conflicts of interest to declare. Dr. Gupta disclosed that he is also an employee and shareholder at Genentech.

Adverse health outcomes were judged on the basis of instrumental or basic activities of daily living (IADL/ADL), while disability was judged by self-reported difficulties in or requiring assistance with at least one IADL or ADL.
 

Frail or prefrail

Almost half of the participants were frail or prefrail, as the authors reported, while 25% had COPD. Among the participants with COPD, 30% had moderate to severe COPD, 6.4% had dyspnea, and almost half had prefrailty, while approximately 7% were classified as frail.

This percentage was 86% higher than it was for participants without COPD, among whom just 3.2% were assessed as frail, at an odds ratio of 1.86 (95% CI, 1.35-2.56). Further adjustments for possible confounders reduced the gap between frail COPD and frail non-COPD participants, but frailty remained significantly associated with COPD, at an OR of 1.61 (95% CI, 1.15-2.26), the investigators note.

Furthermore, compared to those without COPD, a diagnosis of COPD without and with dyspnea was associated with a 1.5- and 4.2-fold increase in prevalent frailty (95% CI, 1.04-2.08; 1.84-9.19), respectively, although not with prefrailty. Again, adjusting for multiple confounders, FEV1%, dyspnea, and both prefrailty and frailty were associated with an approximately twofold higher prevalence of IADL/ADL disability, while the prevalence of IADL/ADL disability for participants with COPD was approximately fourfold higher in those with co-occurring FEV1% less than 80% with either prefrailty, frailty, or dyspnea.

Furthermore, the presence of prefrailty or frailty in combination with a lower FEV1% or dyspnea was associated with a 3.7- to 3.8-fold increased risk of having an IADL or ADL disability.
 

Frailty and mortality

Some 1,116 participants with COPD were followed for a mean of 2,981 days for mortality outcomes. Both FEV1% less than 50% and the presence of prefrailty and frailty almost doubled the risk of mortality, at an adjusted hazard ratio of 1.8 (95% CI, 1.24-2.68) compared to patients with an FEV1% greater than or equal to 80%. In combination with either FEV1% less than 80% or prefrailty/frailty, dyspnea almost more than doubled the risk of mortality, at an HR of 2.4 for both combinations.

“However, the mortality risk of participants with COPD was highest among those with FEV1% less than 80% and prefrailty/frailty,” the authors note, more than tripling mortality risk at an adjusted HR of 3.25 (95% CI, 1.97-5.36). Interestingly, FEV1 less than 80% and prefrailty/frailty – both alone and in combination – were also associated with a twofold to fourfold increased risk of IADL or ADL disability in participants without COPD but were less strongly associated with mortality.

Researchers then went on to create a summary risk score containing all relevant variables with values ranging from 0 to 5. The highest risk category of 3 to 5 was associated with a 7- to 8.5-fold increased risk for IADL and ADL disability and mortality among participants with COPD, and that risk remained high after adjusting for multiple confounders.

Interestingly, frailty did not significantly predict mortality in women, while dyspnea did not significantly predict mortality in men. “Recognition and assessment of physical frailty in addition to FEV1% and dyspnea would allow for more accurate identification and targeted treatment of COPD at risk of future adverse outcomes,” the authors suggest.
 

Frailty scoring system

Asked to comment on the study, Sachin Gupta, MD, a pulmonologist and critical care specialist at Alameda Health System in Oakland, Calif., noted that the current study adds to the body of literature that outcomes in patients with COPD depend as much on objectively measured variables as on qualitative measures. “By applying a frailty scoring system, these researchers were able to categorize frailty and study its impact on patient characteristics and outcomes,” he told this news organization in an email.

The summary risk assessment tool developed and assessed is familiar: It carries parallels to the widely utilized BODE Index, replacing body mass index and 6-minute walk distance with the frailty scale, he added. “Findings from this study support the idea that what meets the eye in face-to-face visits – frailty – can be codified and be part of a tool that is predictive of outcomes,” Dr. Gupta underscored.

The authors had no conflicts of interest to declare. Dr. Gupta disclosed that he is also an employee and shareholder at Genentech.

As a physician first and a mental health clinician second, I hope to provide factual medical information on the Omicron variant to my patients, family members, and friends. I also try to remain curious instead of angry about why some choose not to vaccinate.

The most effective way to encourage people to obtain a vaccination is to use communication free of judgment and criticism, which allows a safe space for the unvaccinated to express their motivations and fears behind their current choice of not vaccinating and explore possible barriers to an alternative option that could lead to vaccination.

As an adult psychiatrist, ADHD specialist, and amateur COVID-19 expert, I’d like to offer 10 reasons why Omicron – which ironically means “small” in Latin, can still cause big destruction. Please share these 10 reasons with your patients.

• If you are not vaccinated, this virus will find you within the next few weeks and likely lead to severe symptoms.
• Long-haul symptoms from COVID-19 infection are still possible even for people who contract a milder case of the Omicron variant.
• The monoclonal antibody and antiviral treatments recently approved by the Food and Drug Administration for pre-exposure prevention of COVID-19 are limited. For many reasons, now is not the best time to play Russian roulette and intentionally get infected with a “mild” variant.
• There are not enough testing sites or over-the-counter rapid COVID tests available to keep up with the demand, and the latter are cost prohibitive for many people.
• Emergency care during the next few weeks for unforeseen non–COVID-related illnesses, such as a sudden heart attack or stroke, may be affected by the shortage of medical providers because of illness, quarantine, and burnout.
• There will be fewer first responders, including EMTs, police officers, and firefighters, because of COVID quarantines from illness and exposure.
• Although most Americans oppose temporary shutdowns, de facto shutdowns might be necessary because of the absence of healthy, COVID-negative individuals to maintain a functional society.
• Omicron math is deceiving, since the risk of hospitalization with Omicron appears to be far lower than with the Delta variant. However, the higher volume of infections with Omicron will offset the lower severity leading to comparable numbers of hospitalizations.
• Omicron has made it difficult for some schools to reopen after the holiday break, and reopening might become even more difficult as the surge progresses. Many schools already were in desperate need of substitute teachers, bus drivers, and additional staff necessary for COVID safety precautions before the emergence of the Omicron variant.
• And, for a less altruistic reason, as if the nine reasons above weren’t enough – if infections continue, especially among the unvaccinated – where the virus mutates the most – this can lead to a trifecta variant that not only evades the immune system and is highly infectious but causes severe disease in both the unvaccinated as well as the vaccinated.

Because of its extremely high transmissibility, the Omicron variant – layered atop Delta – presents great risk to us as a society. We must do all we can as clinicians to educate our patients so that they can protect themselves and their families.

To reduce risks of lung cancer mortality, interventions designed to improve high-risk groups’ uptake of low-dose CT (LDCT) lung cancer screening should focus on perceptions of lung cancer controllability, survival, and perceived effectiveness of changes in behavior, according to analysis of data from the SUMMIT study recently published in the Journal of Thoracic Oncology. Such an approach may be more effective than trying to change risk perceptions.

While 1-year survival among patients diagnosed with early-stage lung cancer is 88%, it is only 19% for those diagnosed with advanced disease. But only 27% of patients are diagnosed with early-stage disease. Screening high-risk asymptomatic adults using LDCT detects early-stage disease and significantly reduces lung cancer mortality, according to Samantha L. Quaife, PhD, of the Wolfson Institute of Population Health at Queen Mary University of London, and associates.

The effectiveness and equity of LDCT lung cancer screening as a population-level early detection strategy is compromised by low uptake among high-risk groups, the authors wrote.

In the United States, only 2% of eligible smokers have been screened since screening was first recommended in 2013. To provide a scientific evidence base for intervention, an understanding of factors making high-risk groups less likely to participate in LDCT screening is critical, Dr. Quaife and colleagues wrote.

Their longitudinal cohort study evaluating psychological correlates of lung cancer screening uptake included 44,000 ever-smokers (aged 55-77 years) who were invited to mail a self-regulatory questionnaire for lung cancer screening. Eligibility for LDCT lung cancer screening and inclusion in the SUMMIT study were further determined through telephone and in-person Lung Health Check (LHC) appointments. The primary outcome was uptake of the invitation to book an LHC appointment by telephone.

Of those invited, 7,966 (18.1%) returned the questionnaire with 7,730 (45% female; mean age, about 64 years) linked to screening uptake data. About 30% reported being current smokers with high tobacco dependence (60.3% smoking within 30 minutes of waking). The analysis from Dr. Quaife and colleagues looked at psychological correlates of lung cancer screening uptake using a psychometrically validated self-regulatory questionnaire for lung cancer screening (SRQ-LCS) to measure psychological constructs hypothesized to be associated with uptake which included consequences, emotional representation, coherence (lung cancer knowledge), treatment control, personal control, risk perception, perceived stigma, response efficacy of smoking cessation, early diagnosis behavioral response, survival from lung cancer, and treatment intention.

Among those who perceived early diagnosis to be more beneficial as a behavioral response, the positive association with uptake was strongest (adjusted odds ratio, 1.37; 95% confidence interval, 1.33-1.41). Those who perceived greater personal control (aOR, 1.09; 95% CI, 1.05-1.11) or believed their risk of lung cancer was high (aOR, 1.08; 95% CI, 1.05-1.10) were also more likely to respond. Other uptake increases were found for those who perceived smoking cessation as an effective means of reducing lung cancer risk or thought the chances of surviving early-stage lung cancer were good or fair (P < .01), and for those who perceived lung cancer as stigmatized (aOR, 1.26; 95% CI, 1.14-1.40). Most of these constructs were also perceived more negatively by current than former smokers.

Income, employment, education, social class, and housing conditions were significantly associated with many of the constructs. Greater affluence correlated with perceived personal control and benefit from early diagnosis, but more negative perceptions of the consequences of lung cancer. Also, those from more affluent areas were more likely to perceive lung cancer to be stigmatized and perceive smoking cessation to be less effective in reducing risk. Current daily smokers were less willing to be treated for early-stage disease, more pessimistic about survival, but had the highest-risk perception scores, at odds with their lower participation in lung screening trials. This contradiction, Dr. Quaife and colleagues suggested, may be explained by current smokers also holding more negative perceptions associated with lower uptake, including negative perceptions of lung cancer controllability, early diagnosis and survival, lower willingness to be treated, and belief that smoking cessation is less effective in reducing risk. All of these undermine positive responses to their high perceived risk.

“These findings pinpoint specific psychological targets for intervention,” the authors wrote. Experimental studies investigating the methods and mechanisms through which these perceptions could be changed are needed.

The study was funded by Cancer Research UK Population Research Fellowship (C50664/A24460) awarded to Dr. Quaife. The study investigators declared no support from financial organizations that might have an interest in the submitted work in the previous 3 years.

Use of a leukotriene receptor antagonist (LTRA) for asthma management did not increase the risk of neuropsychiatric disease, based on data from more than 60,000 asthma patients.

Although LTRAs are established as an effective drug for asthma, the U.S. Food and Drug Administration warnings of the risk for neuropsychiatric (NP) drug reactions – including a boxed warning for montelukast (Singulair) – has raised concerns, writes Ji-Su Shim, MD, of Ewha Womans University, Seoul, South Korea, and colleagues.

However, evidence for such an association is limited, and previous studies have focused only on children and adolescents, and on a single LTRA (montelukast), the researchers say.

In a study published Dec. 1 in the Journal of Allergy and Clinical Immunology: In Practice, the researchers used a Korean national health insurance database to identify 61,571 adult patients with asthma aged 40 years and older between Jan. 2002 and Dec. 2015 with no history of LTRA use.

The patients underwent screening examinations between Jan. 2009 and Dec. 2010, which marked the start of a follow-up period ending on Dec. 31, 2015. The median age of the study population was 61 years, and the mean follow-up period for NPs or other outcomes was approximately 47.6 months for LTRA users and 46.5 months for nonusers. Overall, 11.1% of the study population used pranlukast (Onon), 11% used montelukast, and 0.24% used zafirlukast (Accolate).

A total of 12,168 patients took an LTRA during the follow-up period. The hazard ratio for newly diagnosed neuropsychiatric diseases was not significantly different between LTRA users and nonusers (hazard ratio, 1.01; P = .952) in an adjusted model that included age, sex, pack-years of smoking, alcohol use, physical activity, body mass index, comorbid conditions, other respiratory diseases, and use of other asthma medications.

The most common NPs were dementia, mood disorders, and panic disorders, and the prevalence of each was not significantly different between LTRA users and nonusers (75.4% vs. 76.1% for dementia, 12.7% vs. 12.8% for mood disorders, and 5.6% vs. 3.5% for panic disorders).

A subgroup analysis for associations between the duration of LTRA use and NP disease risk also showed no significant difference between LTRA users and nonusers.

“The mechanism of the development of NP symptoms by LTRAs has not been identified,” the researchers write in their discussion of the study findings. “Because most of NP side effects due to montelukast occur in few patients within 2 weeks of drug administration, it also may have relation with the presence of some genetic polymorphisms involving modification of the normal action or metabolism of LTRAs,” they explained.

The FDA’s boxed warning for montelukast noting the risk of serious mental health side effects has renewed interest in the relationship between NPs and LTRAs, the researchers noted. However, the current study findings support previous randomized controlled trials and larger studies, and the current warnings are based mainly on pharmacovigilance studies, case series, and case reports, they said.

The study findings were limited by several factors, including the retrospective design, the potential for misclassification of asthma diagnosis, the exclusion of temporary NP symptoms that might prompt LTRA discontinuation, and the inability to detect possible differences in ethnicities other than Korean, the researchers note.

However, the results suggest that adverse NP symptoms should not prevent physicians from prescribing LTRAs to selected patients with asthma. Instead, the physician should accompany the prescription with “a word of caution in case any mood changes might occur,” the investigators wrote.

“Further studies, such as randomized controlled trials, are needed to reveal the association between the use of LTRAs and the risk of NP events and/or diseases,” they concluded.

Potential genetic predisposition may drive cases

The relatively rare occurrence of NP symptoms in asthma patients using LTRAs has prompted questions from the medical community on whether the relationship really exists, writes Désirée Larenas-Linnemann, MD, of Médica Sur Clinical Foundation and Hospital, Mexico City, in an accompanying editorial ).

The current study provides information about medications and possible adverse drug reactions, but “great care should be taken in the interpretation of the results from such a study,” she notes. Limitations include not only the possible misclassification of asthma and the homogeneous study population, but also the fact that some NPs, such as dementia, are already common in older adults..

Dr. Larenas-Linnemann shared a story of one of her patients, a 2½-year-old boy who began exhibiting hyperactivity and other strange behaviors while on an LRTA. The toddler’s father had previously reported “horrible nightmares, strange thoughts, and to feel upset, unsecure until he suspended the medication.” Cases such as this support a potential genetic predisposition, with drug metabolism playing a role, and clinicians should take genetic backgrounds into account, she said.

“Even though the current study did not show an association between LTRA use or duration of exposure and the occurrence of NP diseases in Korean adults with asthma, this does not imply such a relationship might be present in other age groups (children-adolescents-adults up to 50 years) or in patients with a different genetic background,” she emphasized.

However, “In the meantime, although LTRA should continue to be prescribed if indicated, an index of suspicion for possible NP effects should be maintained,” Dr. Larenas-Linnemann concluded.

“This study is timely, since the boxed warning for montelukast was issued approximately 1 year ago by the FDA,” Thomas B. Casale, MD, of the University of South Florida, Tampa, said in an interview.

Dr. Casale said he was not surprised by the findings, “since most of the data implicating a potential link between the use of montelukast and neuropsychiatric disorders have not been particularly compelling,” and much of the current information comes from case reports and retrospective studies.

“Furthermore, the data appeared to be somewhat stronger in the pediatric population,” Dr. Casale noted. “This study focused on elderly patients (mean age 61) and included two other leukotriene modifiers. The number of patients receiving montelukast was small (56), which may have also confounded the results,” he noted.

As for clinical implications, “I don’t think this study will change practice,” Dr. Casale said. “As indicated, it is in an elderly population, included only a limited number of patients receiving montelukast, and was in a Korean cohort. All of these factors could have influenced the results,” and the data may not be generalizable to patients elsewhere, including the United States, he said. “Also, the study only included patients with asthma and in the United States; the approval for rhinitis is another important indication to study,” he noted.

Additional research is needed in the form of better prospective studies examining the potential link between montelukast and neuropsychiatric disorders in both the pediatric and adult populations having either asthma or rhinitis, Dr. Casale concluded.

The study received no outside funding. The researchers and Dr. Casale have disclosed no relevant financial relationships. Dr. Larenas-Linnemann disclosed personal fees from Allakos, Armstrong, AstraZeneca, Chiesi, DBV Technologies, Grünenthal, GSK, Mylan/Viatris, Menarini, MSD, Novartis, Pfizer, Sanofi, Siegfried, UCB, Alakos, Gossamer, and Carnot, and grants from Sanofi, AstraZeneca, Novartis, Circassia, UCB, GSK, and the Purina Institute.

Use of a leukotriene receptor antagonist (LTRA) for asthma management did not increase the risk of neuropsychiatric disease, based on data from more than 60,000 asthma patients.

Although LTRAs are established as an effective drug for asthma, the U.S. Food and Drug Administration warnings of the risk for neuropsychiatric (NP) drug reactions – including a boxed warning for montelukast (Singulair) – has raised concerns, writes Ji-Su Shim, MD, of Ewha Womans University, Seoul, South Korea, and colleagues.

However, evidence for such an association is limited, and previous studies have focused only on children and adolescents, and on a single LTRA (montelukast), the researchers say.

In a study published Dec. 1 in the Journal of Allergy and Clinical Immunology: In Practice, the researchers used a Korean national health insurance database to identify 61,571 adult patients with asthma aged 40 years and older between Jan. 2002 and Dec. 2015 with no history of LTRA use.

The patients underwent screening examinations between Jan. 2009 and Dec. 2010, which marked the start of a follow-up period ending on Dec. 31, 2015. The median age of the study population was 61 years, and the mean follow-up period for NPs or other outcomes was approximately 47.6 months for LTRA users and 46.5 months for nonusers. Overall, 11.1% of the study population used pranlukast (Onon), 11% used montelukast, and 0.24% used zafirlukast (Accolate).

A total of 12,168 patients took an LTRA during the follow-up period. The hazard ratio for newly diagnosed neuropsychiatric diseases was not significantly different between LTRA users and nonusers (hazard ratio, 1.01; P = .952) in an adjusted model that included age, sex, pack-years of smoking, alcohol use, physical activity, body mass index, comorbid conditions, other respiratory diseases, and use of other asthma medications.

The most common NPs were dementia, mood disorders, and panic disorders, and the prevalence of each was not significantly different between LTRA users and nonusers (75.4% vs. 76.1% for dementia, 12.7% vs. 12.8% for mood disorders, and 5.6% vs. 3.5% for panic disorders).

A subgroup analysis for associations between the duration of LTRA use and NP disease risk also showed no significant difference between LTRA users and nonusers.

“The mechanism of the development of NP symptoms by LTRAs has not been identified,” the researchers write in their discussion of the study findings. “Because most of NP side effects due to montelukast occur in few patients within 2 weeks of drug administration, it also may have relation with the presence of some genetic polymorphisms involving modification of the normal action or metabolism of LTRAs,” they explained.

The FDA’s boxed warning for montelukast noting the risk of serious mental health side effects has renewed interest in the relationship between NPs and LTRAs, the researchers noted. However, the current study findings support previous randomized controlled trials and larger studies, and the current warnings are based mainly on pharmacovigilance studies, case series, and case reports, they said.

The study findings were limited by several factors, including the retrospective design, the potential for misclassification of asthma diagnosis, the exclusion of temporary NP symptoms that might prompt LTRA discontinuation, and the inability to detect possible differences in ethnicities other than Korean, the researchers note.

However, the results suggest that adverse NP symptoms should not prevent physicians from prescribing LTRAs to selected patients with asthma. Instead, the physician should accompany the prescription with “a word of caution in case any mood changes might occur,” the investigators wrote.

“Further studies, such as randomized controlled trials, are needed to reveal the association between the use of LTRAs and the risk of NP events and/or diseases,” they concluded.

Potential genetic predisposition may drive cases

The relatively rare occurrence of NP symptoms in asthma patients using LTRAs has prompted questions from the medical community on whether the relationship really exists, writes Désirée Larenas-Linnemann, MD, of Médica Sur Clinical Foundation and Hospital, Mexico City, in an accompanying editorial ).

The current study provides information about medications and possible adverse drug reactions, but “great care should be taken in the interpretation of the results from such a study,” she notes. Limitations include not only the possible misclassification of asthma and the homogeneous study population, but also the fact that some NPs, such as dementia, are already common in older adults..

Dr. Larenas-Linnemann shared a story of one of her patients, a 2½-year-old boy who began exhibiting hyperactivity and other strange behaviors while on an LRTA. The toddler’s father had previously reported “horrible nightmares, strange thoughts, and to feel upset, unsecure until he suspended the medication.” Cases such as this support a potential genetic predisposition, with drug metabolism playing a role, and clinicians should take genetic backgrounds into account, she said.

“Even though the current study did not show an association between LTRA use or duration of exposure and the occurrence of NP diseases in Korean adults with asthma, this does not imply such a relationship might be present in other age groups (children-adolescents-adults up to 50 years) or in patients with a different genetic background,” she emphasized.

However, “In the meantime, although LTRA should continue to be prescribed if indicated, an index of suspicion for possible NP effects should be maintained,” Dr. Larenas-Linnemann concluded.

“This study is timely, since the boxed warning for montelukast was issued approximately 1 year ago by the FDA,” Thomas B. Casale, MD, of the University of South Florida, Tampa, said in an interview.

Dr. Casale said he was not surprised by the findings, “since most of the data implicating a potential link between the use of montelukast and neuropsychiatric disorders have not been particularly compelling,” and much of the current information comes from case reports and retrospective studies.

“Furthermore, the data appeared to be somewhat stronger in the pediatric population,” Dr. Casale noted. “This study focused on elderly patients (mean age 61) and included two other leukotriene modifiers. The number of patients receiving montelukast was small (56), which may have also confounded the results,” he noted.

As for clinical implications, “I don’t think this study will change practice,” Dr. Casale said. “As indicated, it is in an elderly population, included only a limited number of patients receiving montelukast, and was in a Korean cohort.

Researchers have known for some time that depression is associated with Alzheimer’s disease (AD), but a causal link has been elusive. Now, using newly available data, they have uncovered genetic evidence of a causal role for depression in AD.

As depression typically affects those in early or midlife and dementia often occurs in later life, “it’s fascinating to see a connection between the two brain illnesses that manifest in different time windows,” coinvestigator Aliza P. Wingo, MD, associate professor of psychiatry and behavioral science, Emory University, Atlanta, said in an interview.

“If we can treat the depression early on, we may help reduce risk for dementia for our patients later in life,” Dr. Wingo said.

The findings were published online Dec. 16, 2021, in Biological Psychiatry.

Postmortem data

The investigators, who are all from the Emory University Center for Neurodegenerative Disease, wanted to clarify the genetic basis underlying the association between the established link between depression and dementia risk.

They used data from the largest and most recent genomewide association studies (GWAS). These included a 2019 analysis of depression among 807,553 individuals and a 2019 study of AD among 455,258 individuals, all of European ancestry. For sensitivity analyses, they used results from two additional AD GWAS.

The researchers also accessed postmortem brain samples from participants in the Religious Orders Study (ROS) and the Rush Memory and Aging Project (MAP). These participants were cognitively normal at enrollment, underwent annual clinical evaluations, and agreed to donate their brains.

They also assessed brain samples donated by participants in the Banner Sun Health Research Institute longitudinal study of healthy aging, Alzheimer’s, and Parkinson’s disease.

The brain samples allowed researchers to use deep brain proteomic data to help determine molecular links between depression and AD.

After quality control, the analysis included 8,356 proteins in 391 ROS/MAP participants and 7,854 proteins in 196 Banner participants.

Results showed a small but significant positive genetic correlation between depression and AD, suggesting the two conditions have a shared genetic basis.

The investigators also applied a framework called “Mendelian randomization” to determine causality between depression and AD.

After assessing the effect of 115 independent single-nucleotide polymorphisms (SNPs) from the GWAS of depression, they uncovered significant evidence “that the SNPs cause depression, which in turn cause AD,” said Dr. Wingo.
 

One-way relationship

The researchers conducted the same analysis on 61 significant SNPs from the GWAS of AD but did not find evidence to conclude AD causes depression.

“We found genetic evidence supporting a causal role of depression in AD but not vice versa,” Dr. Wingo said.

In addition, the investigators identified 75 brain transcripts (messenger RNA) and 28 brain proteins regulated by the depression-predisposing genetic variants. Of these, 46 brain transcripts and seven proteins were significantly associated with at least one AD feature – for example, beta-amyloid, tau tangles, and cognitive trajectory.

“These findings support the notion that the depression risk variants contribute to AD via regulating expression of their corresponding transcripts in the brain,” the investigators wrote.

It is only recently that large enough studies have allowed researchers sufficient power to reach these conclusions, coinvestigator Thomas Wingo, MD, said in an interview.

These additional “insights” into the relationship between depression and AD might “motivate” clinicians more to screen for and treat depressive symptoms, Dr. Aliza Wingo noted.

The new results also have implications for developing therapeutics to treat depression, she said. “If we target the genes, the brain proteins, that are shared risk between depression and AD, the medications that target that gene might mitigate risk for AD later on.”

However, the investigators advised caution. “A lot of this is still unknown,” said Dr. Thomas Wingo.

For example, it is not clear whether successfully treating depression mitigates the eventual risk of dementia, which is “a very important topic of inquiry and one we continue to work on,” he said, adding that a significant number of patients do not respond well to existing antidepressants such as SSRIs.
 

Need for further research

Commenting on the findings, Claire Sexton, DPhil, director of scientific programs and outreach, Alzheimer’s Association, said the study contributes to the debate about whether depression increases risk for AD, whether AD increases risk for depression, or both.

“These newly published findings strengthen our understanding of the role of depression as a risk factor for Alzheimer’s dementia,” said Dr. Sexton, who was not involved with the research.

While experts do not yet fully understand the impact of treating depression on dementia risk, “the findings emphasize the importance of assessing mental health status, particularly depression, and getting it properly diagnosed and treated in a timely manner,” she said.

However, she agreed more research in this area is needed. “Importantly, these findings need replication in broader, more diverse study populations,” Dr. Sexton said.

A study funded by the Alzheimer’s Association may provide more information on the link between depression and AD. It will investigate whether machine learning, an advanced computer science technique, can better predict cognitive decline, compared with traditional methods.

Over a period of 6 months, researchers will collect smartphone conversations from 225 older adults with dementia, mild cognitive impairment, or no cognitive impairment. They will also have data from cognitive tests, brain scans, and biomarkers such as cerebrospinal fluid samples to study brain changes associated with AD.

The novel method of analysis should be able to identify subtle differences in speech quality to indicate which depressive symptoms an individual might be experiencing.

“The study could help us further understand the potential impact of depression in the risk of developing dementia,” said Dr. Sexton.

Dr. Aliza Wingo and Dr. Thomas Wingo reported no relevant financial relationships.

New research offers more insight into potentially dangerous racial disparities in cesarean deliveries: In first-time live births, healthy African-American and Hispanic mothers were 21% and 26% more likely than White mothers, respectively, to deliver by cesarean section despite being low risk. The higher number of cesareans appeared to boost their risk of morbidity.

“A 20% increased odds of cesarean among otherwise healthy, low-risk, nulliparous individuals at term – with limited medical or obstetric explanation – is a significant concern, especially when considering that cesarean is the most common surgical procedure in the U.S.,” said study author Michelle P. Debbink, MD, PhD, an assistant professor with the department of obstetrics and gynecology at the University of Utah, in an interview.

Dr. Debbink and colleagues launched the study, published in the Jan. 2022 issue of Obstetrics & Gynecology, to better understand the racial gap in cesarean sections, which are considered riskier than vaginal deliveries. “Several studies have shown that Black women undergo cesarean more frequently than non-Hispanic White women. Numerous studies also show that Hispanic/Latina women undergo cesarean more frequently than White women, although these data are a bit more mixed,” she said. “What we don’t know, however, is why these differences occur and whether there are clues in the data which can point us toward interventions to close the gap.”

One theory, she said, is that Black and Hispanic women have more comorbidities and therefore more cesareans. To test that idea, the researchers found a cohort of healthy women in a randomized trial that studied the induction of labor.

For the study, they focused on 5,759 women (24.3% Black, 30% Hispanic, 46.6% White). Major differences between the groups included maternal age (average = 21 for Black, 22 for Hispanic, and 26 for White, P < .001), private insurance (17% for Black and Hispanic, 75% for White; P < .001), and full or part-time employment (37% for Black, 31% for Hispanic, and 71% for White; P < .001).

A total of 1,158 of the women (20.1%) underwent cesarean deliveries, accounting for 23% of deliveries by Black women, 22.8% of those by Hispanic women, and 17.6% of those by White women (P < .001). Black women were 21% more likely than White women to give birth via cesarean (adjusted relative risk = 1.21, 95% CI: 1.03-1.42) and Hispanic women were 26% more likely (aRR = 1.26, 95% CI: 1.08-1.46).

The study doesn’t explore why Black and Hispanic women have more cesarean deliveries. However, Dr. Debbink said, “we hypothesize that the difference likely stems more from differing treatment of Black or Hispanic individuals during labor.” It’s unlikely, she said, that these women are more likely to prefer cesarean sections. For one thing, she said, other research hasn’t shown a difference in preferences by race.

The researchers also analyzed maternal morbidity, defined as “transfusion of 4 or more units of red blood cells, any transfusion of other products, postpartum infection, intensive care unit admission, hysterectomy, venous thromboembolism, or maternal death.”

The study found that while few women (2.3%) suffered from morbidity, Black (aRR = 2.05, 95% CI: 1.21-3.47) and Hispanic (aRR = 1.92, 95% CI: 1.17-3.14) women were more likely to suffer from it than White women.

The researchers report that “cesarean birth accounted for an estimated 15.8% (95% CI: 2.1%-48.7%) and 16.5% (95% CI: 4.0%-44.0%) of excess maternal morbidity among non-Hispanic Black and Hispanic people, respectively.”

“Both endometritis and wound complications are much more common among individuals with cesarean, and blood clots, hysterectomy, and ICU admission are also more common after cesarean compared with vaginal delivery,” Dr. Debbink said.

The message of the study, she said, is that the health care system “perpetuates gaps in cesarean delivery for Black and Hispanic individuals compared to White individuals” even in low-risk, first-time live births. “We do not yet know exactly what the right levers are to address this gap, but it is important that we ob-gyns examine our practice patterns and our hospitals’ practice patterns to ensure equity for all our patients.”

Rebecca Delafield, PhD, an assistant professor of Native Hawaiian Health at the University of Hawaii, praised the study as “well-conducted” in an interview. “I agree with the assessment that while the cesarean delivery accounts for a modest proportion of excess morbidity in this study, the impact at the population level is significant,” said Dr. Delafield, who studies health disparities and didn’t take part in the study. “Delivery is complex and the causes of disparities observed are likely multifactorial, therefore research such as this is necessary and compelling.”

She added: “It is becoming increasingly evident that studies investigating racial/ethnic disparities in cesarean delivery and other maternal health outcomes must look beyond maternal behavioral or medical risk factors – e.g., obesity or hypertension – and consider the contribution of a broader set of factors, including societal prejudices.”
