There was a time when I was on the cutting edge of psychiatry and technology. I was the first physician I knew to communicate with my patients by text messages, which left my colleagues aghast. And then, in 2006, I started a blog with two other psychiatrists; they chose to use pseudonyms, but I used my real (and uncommon) first name, well aware that this might leave me a bit exposed.

“You know your patients will read it,” one colleague said when I told him. Was that bad? I had no intention of writing anything I would be embarrassed to have others read. And yes, it’s obviously hard to know how people will react to what you say in another context, but I am a writer, and squelching this part of me would have left me feeling that I’m not living a genuine life. And so I write, always aware that others may be watching over my shoulder.

Social media has also been a part of my life. It is therefore with great interest that I took note of a new trend: Several of my psychiatrist colleagues were taking to TikTok to share their personal experiences in ways that probably would have been unthinkable just a few years past.
 

Psychiatry finds an unexpected new platform

TikTok is an app platform for sharing short-form videos, not the written word. It’s dominated by song and dance videos, sometimes lip-synced, and often recorded by the user holding a phone. The videos are brief, lasting mere seconds to a minute.

TikTok was launched in China in 2016 and became available worldwide in 2018. Since that time, it’s primarily become a venue for younger people, with 41% of users in the 16- to 24-year-old age range. They are skilled at navigating TikTok’s truly overwhelming amount of content, something I have yet to comfortably master as an observer, much less as someone who creates content.

David Puder, MD (@dr.davidpuder) is a psychiatrist in Florida who has not shied away from TikTok. He started making videos on the platform in 2020 as a way to promote his Psychiatry & Psychotherapy Podcast. His videos are casual and informative, and his TikTok description reads: “I am trying to teach things to help you connect better with others.”

“TikTok became another way of promoting mental health ideas,” said Dr. Puder. “There is a lot of bad information out there and my overarching purpose is to try to get people excited about mental health.”

Dr. Puder has nearly 112,000 TikTok followers. There’s a mix of creativity and acting that goes into the production of his videos, which he tends to record from his office or car. They vary in content. Some include music, while others are seconds-long mini-lectures on psychiatric topics. Some are purely educational but can include a joke about how many narcissists it takes to screw in a light bulb. They’re also where I learned that he is more likely to cry at sad movies than is his wife.

“I wish more doctors considered being out there,” Dr. Puder said, “but there is an internal resistance we have to exposing ourselves.”

TikTok and podcasting have been positive experiences for him. “I get emails from followers with notes of gratitude, and l have gotten feedback that people have become mental health professionals because of my social media.”
 

TikTok’s psychiatrist sensation

Melissa Shepard, MD (@doctorshepard_md) is also a psychiatrist who posts content on TikTok. With over a million followers, Dr. Shepard is TikTok’s psychiatrist sensation. She started posting mental health information on Instagram, and then in December 2019 began to cross-post on TikTok. She estimates that she has put up hundreds of videos but does not have an exact number. The Today Show used one of her TikTok videos for a segment on teen mental health.

“It has been cool to contribute to the conversation in this kind of way,” Dr. Shepard said.

The media attention has been a mixed bag for Dr. Shepard. As anyone who talks about psychiatry on social media knows, there are people who are vocal about their antipsychiatry opinions, and Dr. Shepard has not been spared. Sometimes the feedback has been hostile or even threatening.

“There have been ups and downs,” she said. “I have thought about stopping, but then I get these amazing messages from people who tell me that my videos made them realize they needed help. So while it has been a bumpy ride, I feel like I’m doing something good.”

Dr. Shepard’s videos are more personal in that she has used TikTok as a forum to discuss her own mental health struggles. “It’s scary, but it has also been liberating. I want people to know that they can succeed and that we need to get rid of the stigma because it gets in the way. When I was suffering from panic attacks and depression, I thought I was the only medical student with these issues and it meant I couldn’t become a doctor.”

Dr. Shepard estimates that half of her patients found her on TikTok. “I always ask myself, would I be okay with my patients seeing this? My patients are younger and they like that I’m on social media. It makes them feel like they know me before they start treatment.”

As we were talking, Dr. Shepard made note of the fact that having a public persona does not fit in with the “blank slate” rules of a psychodynamic psychotherapy.

She had me wondering how those rules might have been constructed if the internet and social media had existed when psychoanalysis was just developing. Perhaps we’d all be clicking “follow” on Sigmund Freud’s TikTok account.Dr. Miller is a coauthor of “Committed: The Battle Over Involuntary Psychiatric Care” (Baltimore: Johns Hopkins University Press, 2016). She has a private practice and is assistant professor of psychiatry and behavioral sciences at Johns Hopkins, both in Baltimore. She has no disclosures.

A single high dose of the antifungal agent liposomal amphotericin B (L-AmB; AmBisome, Gilead Sciences), with a background regimen of flucytosine and fluconazole, is non-inferior and significantly safer in preventing mortality in HIV-associated cryptococcal meningitis than a conventional seven-day regimen that is the current standard of care, according to a new study.

The much-anticipated results suggest an important alternative amid controversy over the drug’s cost and availability.

“The results of this phase 3 [AMBITION-cm] trial make it clear that this approach is just as good as the current World Health Organization-recommended first-line treatment in preventing death,” first author David S. Lawrence, MD, AMBITION study lead clinician, of the London School of Hygiene and Tropical Medicine, United Kingdom, said in an interview.

“The fact that this was the largest ever trial [on HIV-associated cryptococcal meningitis] conducted to date… gives us a high level of confidence in these results,” he said of the study, which was presented at the virtual annual meeting of the International AIDS Society.

“We believe that this should become the WHO-recommended first-line regimen,” he emphasized.

In commenting on the study, Meg Doherty, MD, PhD, director of global HIV, hepatitis, and STI programs at WHO, agreed that a shorter regimen could be vital, particularly in settings with limited resources.

“The results from the AMBITION trial are important for low- and middle-income countries, where the cost and complexity of implementing the current standard seven-day course of L-ambisome or cryptococcal meningitis treatment can put this out of reach for many,” she told this news organization.

“Simplification that maintains the highest quality of care is an important component of the public health approach for HIV treatment and care,” she added.

Dr. Doherty could not comment on any possible changes to WHO recommendations, which are formulated by an independent guideline development group, but a spokesperson said that “WHO is preparing an updated review of the evidence for treating cryptococcal disease as a first step towards updating guidance.”

Conventional treatment toxicities

Cryptococcal meningitis is a leading cause of death in HIV, and the conventional treatment of amphotericin B deoxycholate, though less expensive than L-AmB, is more toxic, causing anemia, renal impairment, and electrolyte abnormalities, Dr. Lawrence explained

Having previously shown a single 10 mg/kg dose of L-AmB to be as effective as the longer regimen of 14 daily doses in terms of clearing cryptococcus from the cerebrospinal fluid, Dr. Lawrence and his colleagues conducted the phase 3 AMBITION-Cm trial to evaluate the effect on mortality, enrolling 844 patients in Botswana, Malawi, South Africa, Uganda, and Zimbabwe who were HIV-positive and had a first episode of cryptococcal meningitis.

Participants in the study were randomized to treatment either with single, high-dose L-AmB (10 mg/kg), combined with 14 days of flucytosine 100 mg/kg/day and fluconazole 1,200 mg/day or to a control group receiving 7 daily doses of AmB deoxycholate (1 mg/kg) plus 7 days of flucytosine 100 mg/kg/day, followed by 7 days of fluconazole 1,200 mg/day.

All patients were also provided with consolidation therapy of fluconazole 800 mg/day for eight weeks. Of the patients, 60.2% were male, their median age was 37, and their median CD4 count was 27 cells/mm³.

For the primary endpoint in the intention-to-treat analysis of 814 patients, the 10-week mortality rate in the single-dose L-AmB group was 24.82% (101 of 407) and 28.75% (117 of 407) in the control arm, for a difference (-3.93%) that was well within the pre-specified non-inferiority margin of 10%.

As expected, the safety measures were significantly improved with the single-dose of L-AmB: Rates of grade 3 or 4 adverse events within the initial 21 days of treatment in the single-dose L-AmB group were 50% versus 62.3% in the control group, and severe anemia occurred in just 13% of single-dose L-AmB participants, compared with 41% in the AmB deoxycholate control arm (both P < .001), Dr. Lawrence reported.

Furthermore, the average decline in hemoglobin over the first week was 0.3 g/dL in the single-dose L-AmB arm and 1.9 g/dL in the control arm, resulting in the need for more blood transfusions in the control arm (P < .001).

The impact on kidney function was also worse in the higher dose arm, with an average increase in creatinine over the first week of 20.2% in the L-AmB group versus 49.7% in the control group, while hypokalemia and thrombophlebitis were also more common with the higher dose group, Dr. Lawrence noted.

In the adjusted analysis, the single-dose L-AmB measures were in fact superior after adjusting for factors including research site, age, sex, baseline Glasgow Coma Scale, CD4 count, CSF cryptococcal colony-forming units/mL, antiretroviral therapy status, hemoglobin, and CSF opening pressure.

Mortality rate still high – but significantly reduced

The mortality rate of about 25% in the study after the treatment is still significantly higher than typically seen in high-income countries such as the United States, where HIV-associated cryptococcal meningitis is less common and associated with a mortality of roughly 10-15%, Dr. Lawrence noted.

The rate is nevertheless among the lowest mortality rates ever reported within a clinical trial conducted in resource-limited settings, he explained.

“These results are a step in the right direction and a significant improvement on the rates of 40% to 45% reported with two-week L-AmB-based regimens in African settings,” Dr. Lawrence underscored.

Higher cost — but potentially more cost-effective

With a higher cost than AmB deoxycholate, L-AmB’s utilization in resource-limited settings has been a challenge: A single vial of L-AmB ranges from $80 to $200, according to some reports, and while 14-day dosing requires as many as 42 vials of L-AmB, even a 7-day regimen still requires 21 vials.

In comparison, the single-dose L-AmB regimen only requires an average of 10 to 11 vials per patient, but the regimen’s higher safety could translate to far greater cost savings, Dr. Lawrence explained.

“While the AmBisome regimen is technically more expensive in terms of drugs, we expect it to be cost-effective or possibly cost-saving when taking into account that there is less toxicity, fewer blood tests, less transfusions, etc., and possibly shorter duration of hospital admission,” he said.

Cost, supply controversy: ‘Black fungus’-related demand

The drug’s cost — as well as supply issues — have meanwhile become even more of a problem as L-AmB has unexpectedly also become urgently needed in the treatment of mucormycosis in India and Nepal, where the otherwise rare fungal disease, commonly known as “black fungus,” has been increasingly affecting COVID-19 patients and survivors.

Gilead had previously announced in 2018 its intention to make L-AmB more widely available at a price of $16.25 per vial, but “implementation of this has been slow,” Dr. Lawrence said.

As a result, Gilead is facing heightened pressure to implement the lower prices – and also improve substantial supply issues, with Médecins Sans Frontières (Doctors Without Borders) and dozens of other global organizations issuing an open letter to Gilead and partner Viatris in June calling for immediate action to implement the lower price and improve supply of L-AmB.

In a company statement, Gilead responded, detailing its “commit[ment] to the non-profit pricing for the treatment of cryptococcal meningitis” and to efforts to improve the public health crisis in India.

For their part, Dr. Lawrence and his colleagues are working on producing more research on the issue.

“We hope that the conclusive results of the AMBITION trial will give a much needed push to implement this program,” he said.

“We are also currently completing the cost-effectiveness analysis of the study, which we hope will provide additional evidence to support widespread implementation of this regimen and highlight further the urgent need to broaden access to AmBisome and flucytosine,” he said.

The trial was supported by a grant through the European Developing Countries Clinical Trials Partnership (EDCTP), the Swedish International Development Cooperation Agency (SIDA) (TRIA2015-1092), and the Wellcome Trust / Medical Research Council (UK)/UKAID Joint Global Health Trials (MR/P006922/1. The AmBisome was donated by Gilead Sciences. Dr. Lawrence had no disclosures to report.

“The results of this phase 3 [AMBITION-cm] trial make it clear that this approach is just as good as the current World Health Organization-recommended first-line treatment in preventing death,” first author David S. Lawrence, MD, AMBITION study lead clinician, of the London School of Hygiene and Tropical Medicine, United Kingdom, said in an interview.

“The fact that this was the largest ever trial [on HIV-associated cryptococcal meningitis] conducted to date… gives us a high level of confidence in these results,” he said of the study, which was presented at the virtual annual meeting of the International AIDS Society.

“We believe that this should become the WHO-recommended first-line regimen,” he emphasized.

In commenting on the study, Meg Doherty, MD, PhD, director of global HIV, hepatitis, and STI programs at WHO, agreed that a shorter regimen could be vital, particularly in settings with limited resources.

“The results from the AMBITION trial are important for low- and middle-income countries, where the cost and complexity of implementing the current standard seven-day course of L-ambisome or cryptococcal meningitis treatment can put this out of reach for many,” she told this news organization.

“Simplification that maintains the highest quality of care is an important component of the public health approach for HIV treatment and care,” she added.

Dr. Doherty could not comment on any possible changes to WHO recommendations, which are formulated by an independent guideline development group, but a spokesperson said that “WHO is preparing an updated review of the evidence for treating cryptococcal disease as a first step towards updating guidance.”

Conventional treatment toxicities

Cryptococcal meningitis is a leading cause of death in HIV, and the conventional treatment of amphotericin B deoxycholate, though less expensive than L-AmB, is more toxic, causing anemia, renal impairment, and electrolyte abnormalities, Dr. Lawrence explained

Having previously shown a single 10 mg/kg dose of L-AmB to be as effective as the longer regimen of 14 daily doses in terms of clearing cryptococcus from the cerebrospinal fluid, Dr. Lawrence and his colleagues conducted the phase 3 AMBITION-Cm trial to evaluate the effect on mortality, enrolling 844 patients in Botswana, Malawi, South Africa, Uganda, and Zimbabwe who were HIV-positive and had a first episode of cryptococcal meningitis.

Participants in the study were randomized to treatment either with single, high-dose L-AmB (10 mg/kg), combined with 14 days of flucytosine 100 mg/kg/day and fluconazole 1,200 mg/day or to a control group receiving 7 daily doses of AmB deoxycholate (1 mg/kg) plus 7 days of flucytosine 100 mg/kg/day, followed by 7 days of fluconazole 1,200 mg/day.

All patients were also provided with consolidation therapy of fluconazole 800 mg/day for eight weeks. Of the patients, 60.2% were male, their median age was 37, and their median CD4 count was 27 cells/mm³.

For the primary endpoint in the intention-to-treat analysis of 814 patients, the 10-week mortality rate in the single-dose L-AmB group was 24.82% (101 of 407) and 28.75% (117 of 407) in the control arm, for a difference (-3.93%) that was well within the pre-specified non-inferiority margin of 10%.

As expected, the safety measures were significantly improved with the single-dose of L-AmB: Rates of grade 3 or 4 adverse events within the initial 21 days of treatment in the single-dose L-AmB group were 50% versus 62.3% in the control group, and severe anemia occurred in just 13% of single-dose L-AmB participants, compared with 41% in the AmB deoxycholate control arm (both P < .001), Dr. Lawrence reported.

Furthermore, the average decline in hemoglobin over the first week was 0.3 g/dL in the single-dose L-AmB arm and 1.9 g/dL in the control arm, resulting in the need for more blood transfusions in the control arm (P < .001).

The impact on kidney function was also worse in the higher dose arm, with an average increase in creatinine over the first week of 20.2% in the L-AmB group versus 49.7% in the control group, while hypokalemia and thrombophlebitis were also more common with the higher dose group, Dr. Lawrence noted.

In the adjusted analysis, the single-dose L-AmB measures were in fact superior after adjusting for factors including research site, age, sex, baseline Glasgow Coma Scale, CD4 count, CSF cryptococcal colony-forming units/mL, antiretroviral therapy status, hemoglobin, and CSF opening pressure.

Mortality rate still high – but significantly reduced

The mortality rate of about 25% in the study after the treatment is still significantly higher than typically seen in high-income countries such as the United States, where HIV-associated cryptococcal meningitis is less common and associated with a mortality of roughly 10-15%, Dr. Lawrence noted.

The rate is nevertheless among the lowest mortality rates ever reported within a clinical trial conducted in resource-limited settings, he explained.

“These results are a step in the right direction and a significant improvement on the rates of 40% to 45% reported with two-week L-AmB-based regimens in African settings,” Dr. Lawrence underscored.

Higher cost — but potentially more cost-effective

With a higher cost than AmB deoxycholate, L-AmB’s utilization in resource-limited settings has been a challenge: A single vial of L-AmB ranges from $80 to $200, according to some reports, and while 14-day dosing requires as many as 42 vials of L-AmB, even a 7-day regimen still requires 21 vials.

In comparison, the single-dose L-AmB regimen only requires an average of 10 to 11 vials per patient, but the regimen’s higher safety could translate to far greater cost savings, Dr. Lawrence explained.

“While the AmBisome regimen is technically more expensive in terms of drugs, we expect it to be cost-effective or possibly cost-saving when taking into account that there is less toxicity, fewer blood tests, less transfusions, etc., and possibly shorter duration of hospital admission,” he said.

Cost, supply controversy: ‘Black fungus’-related demand

The drug’s cost — as well as supply issues — have meanwhile become even more of a problem as L-AmB has unexpectedly also become urgently needed in the treatment of mucormycosis in India and Nepal, where the otherwise rare fungal disease, commonly known as “black fungus,” has been increasingly affecting COVID-19 patients and survivors.

Gilead had previously announced in 2018 its intention to make L-AmB more widely available at a price of $16.25 per vial, but “implementation of this has been slow,” Dr. Lawrence said.

As a result, Gilead is facing heightened pressure to implement the lower prices – and also improve substantial supply issues, with Médecins Sans Frontières (Doctors Without Borders) and dozens of other global organizations issuing an open letter to Gilead and partner Viatris in June calling for immediate action to implement the lower price and improve supply of L-AmB.

In a company statement, Gilead responded, detailing its “commit[ment] to the non-profit pricing for the treatment of cryptococcal meningitis” and to efforts to improve the public health crisis in India.

For their part, Dr. Lawrence and his colleagues are working on producing more research on the issue.

“We hope that the conclusive results of the AMBITION trial will give a much needed push to implement this program,” he said.

“We are also currently completing the cost-effectiveness analysis of the study, which we hope will provide additional evidence to support widespread implementation of this regimen and highlight further the urgent need to broaden access to AmBisome and flucytosine,” he said.

The trial was supported by a grant through the European Developing Countries Clinical Trials Partnership (EDCTP), the Swedish International Development Cooperation Agency (SIDA) (TRIA2015-1092), and the Wellcome Trust / Medical Research Council (UK)/UKAID Joint Global Health Trials (MR/P006922/1. The AmBisome was donated by Gilead Sciences. Dr. Lawrence had no disclosures to report.

“Purported” weight-loss products –12 dietary supplements and 2 alternative therapies – lack high-quality evidence to back up claims of efficacy, a systematic review by the Obesity Society reports.

Sally Kubetin/MDedge News

Most of the more than 300 published randomized controlled trials in the review were small and short, and only 0.5% found a statistically significant weight loss of up to 5 kg, John A. Batsis, MD, from the University of North Carolina at Chapel Hill, and colleagues reported in the journal Obesity.

“Despite the poor quality of these studies with high degrees of bias, most still failed to show efficacy of the product they were testing,” Srividya Kidambi, MD, from the Medical College of Wisconsin, Milwaukee, and colleagues from the Obesity Society’s Clinical Committee pointed out in an accompanying commentary.

“Yet these are the studies that are often used to support manufacturers’ claims of ‘clinically proven’ in their marketing,” they noted.

Most consumers, they continued, are unaware that these nondrug weight-loss products are not regulated by the Food and Drug Administration, but rather, if their ingredients are “generally regarded as safe,” they are treated as dietary supplements and require little or no testing to show either efficacy or safety.

“Our patients need to become aware that dietary supplements for weight loss are nothing more than a pipe dream, and as clinicians we would do well to talk with our patients and help steer them toward science-based treatments rather than the ‘Wild West’ of dietary supplements that are marketed for weight loss,” Scott Kahan, MD, MPH, coauthor of the review and commentary, told this news organization.

The dietary supplement industry has a strong lobby against legislation for more rigorous requirements for claims, noted Dr. Kahan, of the National Center for Weight and Wellness as well as George Washington University, Washington.

However, “there has to be some level of protection for consumers” who are faced with ads by “healthy skinny people saying this [product] can change your life.”

Clinical providers need to guide patients to “evidence-based interventions to support weight loss such as behavioral weight-loss interventions, [FDA-approved] medications, or bariatric surgery,” said Dr. Batsis, who also coauthored the commentary.

There is a “critical need” for more rigorous trials, and a partnership between researchers, funders, and industry, he added.

According to Dr. Kidambi and colleagues, “the use of these products will continue as long as they are allowed to be marketed with the aforementioned limited federal oversight and there is a lack of access to evidence-based obesity treatments.”

The commentary authors “call on regulatory authorities to critically examine the dietary supplement industry, including their role in promoting misleading claims and marketing products that have the potential to harm patients.”

They also urged public and private health insurance plans to “provide adequate resources for obesity management.”

And clinicians should “consider the lack of evidence for non–FDA-approved dietary supplements and therapies and guide their patients toward tested weight-management approaches.”
 

Subpar evidence, booming industry

“Annual sales of dietary supplements for weight loss are booming with an industry valued at $30 billion worldwide, despite subpar evidence” of efficacy, the commentary authors wrote by way of background.

After the Dietary Supplement Health and Education Act of 1994, the National Institutes of Health’s Office of Dietary Supplements was established “to strengthen the knowledge and understanding of dietary supplements by evaluating scientific information, stimulating and supporting research, and educating the public,” they explained.

However, dietary supplements and alternative therapies are endorsed by influencers and celebrities and marketed as a panacea for obesity and weight gain.
 

Literature review finds scant evidence

Consumers may believe that the “clinically proven” claims of efficacy of these “natural” weight-loss treatments have been thoroughly evaluated for safety and efficacy by the FDA, and clinicians lack information to counsel patients about this.

Therefore, although the Office of Dietary Supplements’ work has importantly advanced the science, the review authors wrote, members of the Obesity Society believed it was important to evaluate and perform a qualitative synthesis of the evidence for efficacy of non–FDA-regulated weight-loss supplements and alternative therapies to better inform clinicians and consumers.

From more than 20,000 citations of 53 dietary supplements and alternative therapies promoted for weight loss, the researchers identified 314 randomized controlled trials of 14 products that each had at least 5 randomized controlled trials.

The two types of alternative therapies in the review were mind-body interventions – which included behavioral therapies (for example, mindfulness and stress management), hypnosis, meditation, or massage – and acupuncture.

Several popular and widely used products (for example, human chorionic gonadotropin, raspberry ketones, nicotinamide adenine dinucleotide, vitamin infusions) did not meet the predefined number of published randomized controlled trials to be eligible for inclusion in the review.

The greatest number of trials were for acupuncture (45 trials), green tea (38), conjugated linoleic acid (31), ephedra with or without caffeine (31), mind-body therapies (22), and calcium and vitamin D (22). There were fewer trials of garcinia and/or hydroxycitrate (15), chitosan (9), phaseolus (7), pyruvate (7), chocolate/cocoa (6), chromium (6), guar gum (5), and phenylpropylamine (5).

Of the 314 studies, only 52 studies (16.5%) demonstrated that the products were efficacious and low risk, and only 16 studies (0.5%) reported a statistically significant between-group weight loss (0.3-4.93 kg).

For more information, in addition to their review and commentary, the authors refer clinicians to a dietary supplement label database.

The study was supported in part by grants from the National Institute on Aging. Dr. Batsis reported equity in SynchroHealth. Dr. Kidambi reported being the medical director for TOPS Center for Metabolic Health at the Medical College of Wisconsin, which is supported by TOPS. Dr. Kahan reported serving as a consultant for Novo Nordisk, Vivus, Gelesis, and Pfizer.

In combing the genome, scientists can use genetic clues to determine a person’s risk for psychiatric disease and even identify new drug targets. But the benefits of these discoveries will be limited to people of European descent.

Nearly 90% of participants in genome-wide association studies (GWASs), which search for gene variants linked to disease, are of European ancestry. This Eurocentric focus threatens to widen existing disparities in racial and ethnic mental health.

The significant downsides of genomics’ one-track mind

One obstacle hindering therapeutic advances in psychiatry is a shallow understanding of the mechanisms of disorders. “The biggest problem in terms of advancing research for mental health conditions is that we don’t understand the underlying biology,” says Laramie Duncan, PhD, assistant professor of psychiatry and behavioral sciences at Stanford (Calif.) University. “Genetics is one of the best ways to systematically look for new clues about the underlying biology.”

At the advent of genomic research, scientists thought it best to study DNA from people of a single ancestry from one continent. “Researchers for a long time held the idea that it was going to be too complicated to include multiple ancestries in the first rounds of genetic analyses,” says Dr. Duncan.

Studying DNA from someone with ancestors from multiple parts of the world wasn’t compatible with methods used in the early days of GWASs. “Individual parts of a person’s DNA can be linked back to one region of the world or another, and most of our methods essentially assume that all of a person’s DNA came from one region of the world,” says Dr. Duncan.

Because many genes are usually involved in psychiatric disorders, scientists need large numbers of participants to detect uncommon, influential variants. Early research was concentrated in North America and Europe so that scientists could readily collect samples from people of European ancestry.

“It then went out of hand because it became routine practice to use only this one group, essentially White, European ancestry people,” says Karoline Kuchenbaecker, PhD, associate professor of psychiatry at University College London.

Yet findings from one population won’t necessarily translate to others. “And that’s exactly what has been shown,” says Dr. Teferra. Polygenic risk scores developed for schizophrenia from European samples, for example, perform poorly among people of African ancestry, although among Europeans, they are strongly effective at differentiating European individuals with and those without schizophrenia. Moreover, drugs that target a gene identified from studies in European populations may be harmful to other groups.

Studies drawn from a diverse pool of participants would benefit a wider swath of humanity. They would also allow scientists to discover small areas of overlap in genomes of different populations, which would help them close in on the true biology of diseases and ensure that “we’re all benefiting from more diverse data in genetics and psychiatric genetics,” says Dr. Kuchenbaecker.
 

New efforts aim at filling the gaps

Genomic studies are featuring more people of non-European ancestry, but most of that improvement comes from populations of Asian ancestry, not African, Latin American, or Indigenous ancestry.

Efforts to increase representation of persons of African ancestry have largely focused on African Americans; fewer efforts have extended to the African continent, home to the most genetically diverse populations. Even fewer have focused on mental health. “The little that was being done was on a very small scale,” says Karestan Koenen, PhD, a professor at Harvard School of Public Health, Boston.

With this in mind, researchers from institutions in Kenya, Uganda, South Africa, and Ethiopia partnered with researchers at the Broad Institute of the Massachusetts Institute of Technology and Harvard to conduct the largest GWAS of psychiatric disorders in Africa. Dr. Koenen leads the project, Neuropsychiatric Genetics of African Populations–Psychosis (NeuroGAP-Psychosis), which will analyze DNA from over 35,000 people of African ancestry in each of these four countries. Investigators will compare the half of participants who have no history of psychosis with the half with schizophrenia or bipolar disorder in the hopes of identifying the genetic determinants of psychosis.

“Then any potential intervention or therapeutics that will be developed will also be useful for Africans,” says Dr. Teferra, a NeuroGAP principal investigator. Because of the tremendous degree of genetic diversity among people on the continent, however, findings still might not translate to all African populations.

But correcting equity problems in genomics isn’t as simple as recruiting people with non-European backgrounds, especially if those people are unfamiliar with research or have been subject to scientific exploitation. “Special care needs to be taken to, first of all, provide information that’s appropriate [to participants], but also motivate people to take part and then find ways to keep these communities involved and understand what they’re interested in,” says Dr. Kuchenbaecker, who is not involved with NeuroGAP.

For NeuroGAP, the team needed to work with ethical committees at all of the institutions involved, ensure research materials were appropriate for each community’s cultural context, and gain the trust of local communities.

“One of the biggest criticisms within the scientific world is that people from more endowed countries just fly in, bully everyone, collect the data, and leave, with no credit to the local scientists or communities,” says NeuroGAP principal investigator Lukoye Atwoli, MMed, PhD, professor of psychiatry and dean of the Medical College, East Africa, at the Aga Khan University, Nairobi, Kenya. “That is one of the biggest pitfalls we had to grapple with.”

To address that concern, NeuroGAP is training local researchers and is providing them with requested resources so they can carry out similar studies in the future. “We will be looking to address a real need in the academic community and in clinical service delivery,” says Dr. Atwoli.

Dr. Kuchenbaecker says that NeuroGAP demonstrates features necessary for projects seeking to improve equity in psychiatric genomics. “What they’re doing right is recruiting really large numbers, recruiting from different African countries, and involving African investigators,” she says.

In the Americas, Janitza Montalvo-Ortiz, PhD, assistant professor in the Division of Genetics, department of psychiatry, Yale University, New Haven, Conn., and her colleagues are expanding psychiatric genomics projects in Latin America. She co-founded the Latin American Genomics Consortium in 2019, a network of scientists supporting psychiatric genomic research in the region. The consortium also involves the Neuropsychiatric Genetics in Mexican Populations project, which is similar to NeuroGAP and is also led by Dr. Koenan.

The study of Latin American populations is complicated, because genes in these populations reflect Indigenous American, European, and African ancestries. Even when investigators sampled DNA from Latin American individuals, that data often went unused. “Now with new methods emerging to allow us to properly analyze admixed populations in GWAS studies, we’re making efforts to compile different datasets scattered across different large-scale cohorts,” says Dr. Montalvo-Ortiz. “Our ultimate goal is to conduct the first large-scale LatinX GWAS of psychiatry,” she says.

With these projects, researchers hope that new psychiatric research will produce clinical advances for people historically left on the sidelines of genomic studies. By involving their communities in genomic research, “whatever is going to be developed will also benefit our community,” says Dr. Teferra. “We will not be left out.”

They would also allow scientists to discover small areas of overlap in genomes of different populations, which would help them close in on the true biology of diseases and ensure that “we’re all benefiting from more diverse data in genetics and psychiatric genetics,” says Dr. Kuchenbaecker.
 

New efforts aim at filling the gaps

Genomic studies are featuring more people of non-European ancestry, but most of that improvement comes from populations of Asian ancestry, not African, Latin American, or Indigenous ancestry.

Efforts to increase representation of persons of African ancestry have largely focused on African Americans; fewer efforts have extended to the African continent, home to the most genetically diverse populations. Even fewer have focused on mental health. “The little that was being done was on a very small scale,” says Karestan Koenen, PhD, a professor at Harvard School of Public Health, Boston.

With this in mind, researchers from institutions in Kenya, Uganda, South Africa, and Ethiopia partnered with researchers at the Broad Institute of the Massachusetts Institute of Technology and Harvard to conduct the largest GWAS of psychiatric disorders in Africa. Dr. Koenen leads the project, Neuropsychiatric Genetics of African Populations–Psychosis (NeuroGAP-Psychosis), which will analyze DNA from over 35,000 people of African ancestry in each of these four countries. Investigators will compare the half of participants who have no history of psychosis with the half with schizophrenia or bipolar disorder in the hopes of identifying the genetic determinants of psychosis.

“Then any potential intervention or therapeutics that will be developed will also be useful for Africans,” says Dr. Teferra, a NeuroGAP principal investigator. Because of the tremendous degree of genetic diversity among people on the continent, however, findings still might not translate to all African populations.

But correcting equity problems in genomics isn’t as simple as recruiting people with non-European backgrounds, especially if those people are unfamiliar with research or have been subject to scientific exploitation. “Special care needs to be taken to, first of all, provide information that’s appropriate [to participants], but also motivate people to take part and then find ways to keep these communities involved and understand what they’re interested in,” says Dr. Kuchenbaecker, who is not involved with NeuroGAP.

For NeuroGAP, the team needed to work with ethical committees at all of the institutions involved, ensure research materials were appropriate for each community’s cultural context, and gain the trust of local communities.

“One of the biggest criticisms within the scientific world is that people from more endowed countries just fly in, bully everyone, collect the data, and leave, with no credit to the local scientists or communities,” says NeuroGAP principal investigator Lukoye Atwoli, MMed, PhD, professor of psychiatry and dean of the Medical College, East Africa, at the Aga Khan University, Nairobi, Kenya. “That is one of the biggest pitfalls we had to grapple with.”

To address that concern, NeuroGAP is training local researchers and is providing them with requested resources so they can carry out similar studies in the future. “We will be looking to address a real need in the academic community and in clinical service delivery,” says Dr. Atwoli.

Dr. Kuchenbaecker says that NeuroGAP demonstrates features necessary for projects seeking to improve equity in psychiatric genomics. “What they’re doing right is recruiting really large numbers, recruiting from different African countries, and involving African investigators,” she says.

In the Americas, Janitza Montalvo-Ortiz, PhD, assistant professor in the Division of Genetics, department of psychiatry, Yale University, New Haven, Conn., and her colleagues are expanding psychiatric genomics projects in Latin America. She co-founded the Latin American Genomics Consortium in 2019, a network of scientists supporting psychiatric genomic research in the region. The consortium also involves the Neuropsychiatric Genetics in Mexican Populations project, which is similar to NeuroGAP and is also led by Dr. Koenan.

The study of Latin American populations is complicated, because genes in these populations reflect Indigenous American, European, and African ancestries. Even when investigators sampled DNA from Latin American individuals, that data often went unused. “Now with new methods emerging to allow us to properly analyze admixed populations in GWAS studies, we’re making efforts to compile different datasets scattered across different large-scale cohorts,” says Dr. Montalvo-Ortiz. “Our ultimate goal is to conduct the first large-scale LatinX GWAS of psychiatry,” she says.

With these projects, researchers hope that new psychiatric research will produce clinical advances for people historically left on the sidelines of genomic studies. By involving their communities in genomic research, “whatever is going to be developed will also benefit our community,” says Dr. Teferra. “We will not be left out.”

In combing the genome, scientists can use genetic clues to determine a person’s risk for psychiatric disease and even identify new drug targets. But the benefits of these discoveries will be limited to people of European descent.

Nearly 90% of participants in genome-wide association studies (GWASs), which search for gene variants linked to disease, are of European ancestry. This Eurocentric focus threatens to widen existing disparities in racial and ethnic mental health.

The significant downsides of genomics’ one-track mind

One obstacle hindering therapeutic advances in psychiatry is a shallow understanding of the mechanisms of disorders. “The biggest problem in terms of advancing research for mental health conditions is that we don’t understand the underlying biology,” says Laramie Duncan, PhD, assistant professor of psychiatry and behavioral sciences at Stanford (Calif.) University. “Genetics is one of the best ways to systematically look for new clues about the underlying biology.”

At the advent of genomic research, scientists thought it best to study DNA from people of a single ancestry from one continent. “Researchers for a long time held the idea that it was going to be too complicated to include multiple ancestries in the first rounds of genetic analyses,” says Dr. Duncan.

Studying DNA from someone with ancestors from multiple parts of the world wasn’t compatible with methods used in the early days of GWASs. “Individual parts of a person’s DNA can be linked back to one region of the world or another, and most of our methods essentially assume that all of a person’s DNA came from one region of the world,” says Dr. Duncan.

Because many genes are usually involved in psychiatric disorders, scientists need large numbers of participants to detect uncommon, influential variants. Early research was concentrated in North America and Europe so that scientists could readily collect samples from people of European ancestry.

“It then went out of hand because it became routine practice to use only this one group, essentially White, European ancestry people,” says Karoline Kuchenbaecker, PhD, associate professor of psychiatry at University College London.

Yet findings from one population won’t necessarily translate to others. “And that’s exactly what has been shown,” says Dr. Teferra. Polygenic risk scores developed for schizophrenia from European samples, for example, perform poorly among people of African ancestry, although among Europeans, they are strongly effective at differentiating European individuals with and those without schizophrenia. Moreover, drugs that target a gene identified from studies in European populations may be harmful to other groups.

Studies drawn from a diverse pool of participants would benefit a wider swath of humanity. They would also allow scientists to discover small areas of overlap in genomes of different populations, which would help them close in on the true biology of diseases and ensure that “we’re all benefiting from more diverse data in genetics and psychiatric genetics,” says Dr. Kuchenbaecker.

The Food and Drug Administration has approved the first high-frequency spinal cord stimulation (SCS) therapy for treating painful diabetic neuropathy (PDN).

The approval is specific for the treatment of chronic pain associated with PDN using the Nevro’s Senza System with 10 kHz stimulation. It is intended for patients whose pain is refractory to, or who can’t tolerate, conventional medical treatment. According to the company, there are currently about 2.3 million individuals with refractory PDN in the United States.

The 10 kHz device, called HFX, involves minimally invasive epidural implantation of the stimulator device, which delivers mild electrical impulses to the nerves to interrupt pain signal to the brain. Such spinal cord stimulation “is a straightforward, well-established treatment for chronic pain that’s been used for over 30 years,” according to the company, although this is the first approval of the modality specifically for PDN.

Asked to comment, Rodica Pop-Busui MD, PhD, the Larry D. Soderquist Professor in Diabetes at the University of Michigan, Ann Arbor, said that “the approval of the Nevro 10kHz high-frequency spinal cord stimulation to treat pain associated with diabetic neuropathy has the potential for benefit for many patients with diabetes and painful diabetic peripheral neuropathy.”

She noted that, “although there are several other pharmacological agents that currently carry the FDA approval for PDN, this is a condition that is notoriously difficult to treat, particularly when taking into account the actual number needed to treat with a specific agent to achieve a clinically meaningful pain reduction, as well as the spectrum of side effects and drug-drug interactions in a patient population that require many other additional agents to manage diabetes and comorbidities on a daily basis. Thus, this new therapeutic approach besides effective pain reduction has the additional benefit of bypassing drug interactions.” Dr. Pop-Busui was the lead author on the American Diabetes Association’s 2017 position statement on diabetic neuropathy.

She also cautioned, on the other hand, that “it is not very clear yet how easy it will be for all eligible patients to have access to this technology, what will be the actual costs, the insurance coverage, or the acceptance by patients across various sociodemographic backgrounds from the at-large clinical care. However, given the challenges we encounter to treat diabetic neuropathy and particularly the pain associated with it, it is quite encouraging to see that the tools available to help our patients are now broader.”

Both 6-and 12-month results show benefit

The FDA approval was based on 6-month data from a prospective, multicenter, open-label randomized clinical trial published in JAMA Neurology.

Use of the 10-kHz SCS device was compared with conventional treatment alone in 216 patients with PDN refractory to gabapentinoids and at least one other analgesic class and lower limb pain intensity of 5 cm or more on a 10-cm visual analog scale.

The primary endpoint, percentage of participants reporting 50% pain relief or more without worsening of baseline neurologic deficits at 3 months, was met by 5 of 94 (5%) patients in the conventional group, compared with 75 of 95 (79%) with the 10-kHz SCS plus conventional treatment (P < .001).

Infections requiring device explant occurred in two patients in the 10-kHz SCS group (2%).

At 12 months, those in the original SCS group plus 86% of subjects given the option to cross over from the conventional treatment group showed “clear and sustained” benefits of the 10-kHz SCS with regard to lower-limb pain, pain interference with daily living, sleep quality, and activity, Erika Petersen, MD, director of the section of functional and restorative neurosurgery at the University of Arkansas for Medical Sciences, Little Rock , reported at the 2021 annual scientific sessions of the ADA.

Infection was the most common study-related adverse event, affecting 8 of 154 patients with the SCS implants (5.2%). Three resolved with conservative treatment and five (3.2%) required removal of the device.

The patients will be followed for a total of 24 months.

Commercial launch of HFX in the United States will begin immediately, the company said.

Dr. Pop-Busui has received consultant fees in the last 12 months from Averitas Pharma, Boehringer Ingelheim, Nevro, and Novo Nordisk. Dr. Petersen has financial relationships with Nevro, Medtronic, and several other neuromodulator makers.

The 4-year-old boy and his grandmother are out for stroll around the neighborhood, walking hand in hand.

“Let’s sit on the bench and talk,” the boy says.

“Okay,” says the grandmother and they climb up onto the high bench and look out across the quiet road to a small garden beyond.

“What would you like to talk about?” his grandmother asks.

“You first,” he says.

“Okay, let’s see ... the grandmother and the grandson are out for a walk and they see a bench to sit on. They climb up and look around. They see the daffodils and the white clouds in the blue sky. The breeze is blowing gently. It is a happy day. Your turn; what would you like to talk about?”

“Nanna and Papa.”

“Do you miss Papa?”

“Yes.”

“It has been a whole year since he died.”

“A long, long time.”

“He loved you very much.”

“Yes,” the boy replies.

“Nanna must miss him very much. She must be lonely without him.”

The boy nods.

They sit on for a while, watching the occasional car and the occasional bird pass by. The boy and the grandmother are quiet and contemplative.

“Okay, let’s go,” he says and jumps down, ready to continue their walk.
 

The Friendship Bench

It must have been such an experience that gave Dixon Chibanda, MD, MPH, PhD, a psychiatrist from Zimbabwe, his brilliant idea. He trained grandmothers in evidence-based talk therapy and sat them on a bench in the park with his patients.^1,2 He founded the Friendship Bench in 2006 in the Harare township of Mbare with 14 grandmothers. There are more than 300 grandmothers sitting on benches, listening, and providing cognitive-behavioral therapy–informed interventions because he could find no therapists in the community and he found that, with a little training, these grandmothers could provide effective culturally sensitive interventions.

Originally, the sessions were conducted in Shona, the predominant native language in Zimbabwe, but since 2017, the sessions are also in English. By 2017, the Friendship Bench had helped more than 30,000 people. The method has been empirically vetted and expanded to countries beyond, including the United States. Dr. Chibanda’s Friendship Bench serves as a blueprint for any community interested in bringing affordable, accessible, and highly effective mental health services to its residents. Dr. Chibanda said: “Imagine if we could create a global network of grandmothers in every major city in the world.”³The Friendship Bench is also used with other illnesses, such as HIV, to improve medication compliance.⁴ Participants in this study reported that the Friendship Bench had a critical role in helping them accept their HIV status, citing the grandmothers’ empathic attitude, their normalization of the reality of living with HIV, and their encouragement of young people to socialize with peers and be free of guilt. Many recipients also described enhanced health and well-being.
 

Why grandmothers?

Have you heard of the evolutionary importance of grandmothers? The grandmother hypothesis is an adaptationist explanation for the fact that the human female lifespan extends beyond the period of fertility. A third of the average human female life span is post menopause. Does such a long female postreproductive life span have a reason, inquired Mwenza Blell, PhD.⁵

Peter B. Medawar, PhD,6 and Kristen Hawkes, PhD,⁷ suggested that grandparents influence their own fitness by their actions toward their grandchildren. International fieldwork has revealed that the situation is less clear than their hypothesis. In industrialized countries, grandmaternal support is often financial or emotional. Two meta-analyses of largely the same group of studies investigating grandmother effects have come up with differing conclusions. Rebecca Sear, PhD, and Ruth Mace, PhD, conclude that grandmothers are “almost universally” beneficial, while acknowledging some variation in the effects of paternal grandmothers.⁸ Maternal grandparents appear to invest more in their grandchildren than paternal grandparents. Beverly I. Strassmann, PhD, and Wendy M. Garrard, PhD, concluded that, in patrilineal societies, survival of maternal grandparents is associated with survival of grandchildren and suggest this may represent covert matriliny.⁹

Examining specific time periods, maternal grandmothers may have greatest effect on survival of grandchildren at the time of weaning, a time when increased pathogenic exposure is a threat to survival. Paternal grandmothers may influence the survival of grandchildren during the early period of life (1-12 months) and to influence the condition of their daughters-in-law during pregnancy. The fact that grandmothers share one X chromosome with their sons’ daughters, none with their sons’ sons, and have a 50% chance of sharing an X chromosome with their daughters’ children is suggested to explain the patterns of survival observed in these studies than a simple maternal/paternal division.

In low- and middle-income countries, grandmothers and older women are seen as owners of traditional knowledge, and influence many decisions about childcare, help with domestic work, and emotional support and advice.¹⁰ Studies find a significant positive impact on breastfeeding when grandmothers of the infants had their own breastfeeding experience or were positively inclined toward breastfeeding, although one Chinese study found that highly educated grandmothers were associated with decreased exclusive breastfeeding.¹¹ Despite this, most health programs target individual new mothers, without an understanding of the family and who else influences decisions.

Grandchildren and grandparents benefit from intergenerational activities with improved health and well-being of both generations. When older adults are involved in raising children, there is a significant reduction in the incidence of behavioral problems in childhood and adolescence. Grandparents improve grandchild outcomes, when measured by coresidence, caregiving, financial, and other support. The grandchild outcomes include physical health, socioemotional well-being, and cognitive development.¹²

Are there ‘grandparent genes?’

Flavio Schwarz, PhD, and colleagues think that variants of APOE and CD33 protect against heart disease and Alzheimer’s disease, allowing older people to live longer with better functioning hearts and brains – thus enabling transfer of wisdom from older to younger generations.¹³ While this logic may be a bit of a stretch, it does lead to a more interesting question: What has wisdom got to do with it?

When I ask psychiatrists what they think about wisdom, they give a variety of answers. Dilip Jeste, MD, a geriatric psychiatrist who studies successful aging, helped develop a measurable vision of wisdom.¹⁴ Wisdom is defined as a “multidimensional human trait that includes good social decision-making and pragmatic knowledge of life, prosocial attitudes and behaviors such as empathy and compassion, emotional homeostasis with a tendency to favor positive emotions, reflection and self-understanding, acknowledgment of and coping effectively with uncertainty, and decisiveness.”¹⁵ Others suggest that they include spirituality, openness to new experience, and a sense of humor.¹⁶ A scale called the San Diego Wisdom scale (SD-WISE) was created, using 524 community-dwelling adults aged 25-104 years. These subjects comprised a high proportion of White adults and individuals with a higher education, thus lacking diversity. Lack of diversity perpetuates generalizations, and like all sociocultural constructs, truth is specific to the population studied. High scores on the SD-WISE are positively correlated with good mental health, self-ratings of successful aging, mastery, resilience, happiness, and satisfaction with life.

Which brings us back to the grandmothers on the bench: Can someone please give them the SD-WISE scale and confirm several hypotheses? I would like to know whether a pragmatic knowledge of life is a recognized grandmotherly quality, suitable for the bench.

The 4-year-old boy and his grandmother are out for stroll around the neighborhood, walking hand in hand.

“Let’s sit on the bench and talk,” the boy says.

“Okay,” says the grandmother and they climb up onto the high bench and look out across the quiet road to a small garden beyond.

“What would you like to talk about?” his grandmother asks.

“You first,” he says.

“Okay, let’s see ... the grandmother and the grandson are out for a walk and they see a bench to sit on. They climb up and look around. They see the daffodils and the white clouds in the blue sky. The breeze is blowing gently. It is a happy day. Your turn; what would you like to talk about?”

“Nanna and Papa.”

“Do you miss Papa?”

“Yes.”

“It has been a whole year since he died.”

“A long, long time.”

“He loved you very much.”

“Yes,” the boy replies.

“Nanna must miss him very much. She must be lonely without him.”

The boy nods.

They sit on for a while, watching the occasional car and the occasional bird pass by. The boy and the grandmother are quiet and contemplative.

“Okay, let’s go,” he says and jumps down, ready to continue their walk.
 

The Friendship Bench

It must have been such an experience that gave Dixon Chibanda, MD, MPH, PhD, a psychiatrist from Zimbabwe, his brilliant idea. He trained grandmothers in evidence-based talk therapy and sat them on a bench in the park with his patients.^1,2 He founded the Friendship Bench in 2006 in the Harare township of Mbare with 14 grandmothers. There are more than 300 grandmothers sitting on benches, listening, and providing cognitive-behavioral therapy–informed interventions because he could find no therapists in the community and he found that, with a little training, these grandmothers could provide effective culturally sensitive interventions.

Originally, the sessions were conducted in Shona, the predominant native language in Zimbabwe, but since 2017, the sessions are also in English. By 2017, the Friendship Bench had helped more than 30,000 people. The method has been empirically vetted and expanded to countries beyond, including the United States. Dr. Chibanda’s Friendship Bench serves as a blueprint for any community interested in bringing affordable, accessible, and highly effective mental health services to its residents. Dr. Chibanda said: “Imagine if we could create a global network of grandmothers in every major city in the world.”³The Friendship Bench is also used with other illnesses, such as HIV, to improve medication compliance.⁴ Participants in this study reported that the Friendship Bench had a critical role in helping them accept their HIV status, citing the grandmothers’ empathic attitude, their normalization of the reality of living with HIV, and their encouragement of young people to socialize with peers and be free of guilt. Many recipients also described enhanced health and well-being.
 

Why grandmothers?

Have you heard of the evolutionary importance of grandmothers? The grandmother hypothesis is an adaptationist explanation for the fact that the human female lifespan extends beyond the period of fertility. A third of the average human female life span is post menopause. Does such a long female postreproductive life span have a reason, inquired Mwenza Blell, PhD.⁵

Peter B. Medawar, PhD,6 and Kristen Hawkes, PhD,⁷ suggested that grandparents influence their own fitness by their actions toward their grandchildren. International fieldwork has revealed that the situation is less clear than their hypothesis. In industrialized countries, grandmaternal support is often financial or emotional. Two meta-analyses of largely the same group of studies investigating grandmother effects have come up with differing conclusions. Rebecca Sear, PhD, and Ruth Mace, PhD, conclude that grandmothers are “almost universally” beneficial, while acknowledging some variation in the effects of paternal grandmothers.⁸ Maternal grandparents appear to invest more in their grandchildren than paternal grandparents. Beverly I. Strassmann, PhD, and Wendy M. Garrard, PhD, concluded that, in patrilineal societies, survival of maternal grandparents is associated with survival of grandchildren and suggest this may represent covert matriliny.⁹

Examining specific time periods, maternal grandmothers may have greatest effect on survival of grandchildren at the time of weaning, a time when increased pathogenic exposure is a threat to survival. Paternal grandmothers may influence the survival of grandchildren during the early period of life (1-12 months) and to influence the condition of their daughters-in-law during pregnancy. The fact that grandmothers share one X chromosome with their sons’ daughters, none with their sons’ sons, and have a 50% chance of sharing an X chromosome with their daughters’ children is suggested to explain the patterns of survival observed in these studies than a simple maternal/paternal division.

In low- and middle-income countries, grandmothers and older women are seen as owners of traditional knowledge, and influence many decisions about childcare, help with domestic work, and emotional support and advice.¹⁰ Studies find a significant positive impact on breastfeeding when grandmothers of the infants had their own breastfeeding experience or were positively inclined toward breastfeeding, although one Chinese study found that highly educated grandmothers were associated with decreased exclusive breastfeeding.¹¹ Despite this, most health programs target individual new mothers, without an understanding of the family and who else influences decisions.

Grandchildren and grandparents benefit from intergenerational activities with improved health and well-being of both generations. When older adults are involved in raising children, there is a significant reduction in the incidence of behavioral problems in childhood and adolescence. Grandparents improve grandchild outcomes, when measured by coresidence, caregiving, financial, and other support. The grandchild outcomes include physical health, socioemotional well-being, and cognitive development.¹²

Are there ‘grandparent genes?’

Flavio Schwarz, PhD, and colleagues think that variants of APOE and CD33 protect against heart disease and Alzheimer’s disease, allowing older people to live longer with better functioning hearts and brains – thus enabling transfer of wisdom from older to younger generations.¹³ While this logic may be a bit of a stretch, it does lead to a more interesting question: What has wisdom got to do with it?

When I ask psychiatrists what they think about wisdom, they give a variety of answers. Dilip Jeste, MD, a geriatric psychiatrist who studies successful aging, helped develop a measurable vision of wisdom.¹⁴ Wisdom is defined as a “multidimensional human trait that includes good social decision-making and pragmatic knowledge of life, prosocial attitudes and behaviors such as empathy and compassion, emotional homeostasis with a tendency to favor positive emotions, reflection and self-understanding, acknowledgment of and coping effectively with uncertainty, and decisiveness.”¹⁵ Others suggest that they include spirituality, openness to new experience, and a sense of humor.¹⁶ A scale called the San Diego Wisdom scale (SD-WISE) was created, using 524 community-dwelling adults aged 25-104 years. These subjects comprised a high proportion of White adults and individuals with a higher education, thus lacking diversity. Lack of diversity perpetuates generalizations, and like all sociocultural constructs, truth is specific to the population studied. High scores on the SD-WISE are positively correlated with good mental health, self-ratings of successful aging, mastery, resilience, happiness, and satisfaction with life.

Which brings us back to the grandmothers on the bench: Can someone please give them the SD-WISE scale and confirm several hypotheses? I would like to know whether a pragmatic knowledge of life is a recognized grandmotherly quality, suitable for the bench.

With 49% of the U.S. population fully vaccinated against SARS-CoV-2, a new study highlights the degree of vaccine hesitancy among patients with rheumatic disease to get the vaccine.

Halfpoint Images/Moment/Getty Images

The international study, published in May 2021 in Rheumatology, suggests that, of 1,258 patients surveyed worldwide, approximately 40% of patients said they would decline the vaccine.

“Sometimes it’s helpful to talk through their concerns,” said Jeffrey Curtis, MD, MPH, a University of Alabama at Birmingham rheumatologist who leads the American College of Rheumatology COVID-19 vaccine task force. Dr. Curtis recently reviewed the current literature on COVID-19 vaccination in patients with rheumatic and musculoskeletal diseases (RMDs) at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.

COVID-19 vaccinations for patients with autoimmune inflammatory rheumatic disease (AIIRD) is not straightforward. The immune response can be blunted by existing treatments and disease flares can occur.

The latest version of COVID-19 vaccination guidance for patients with RMDs from the ACR addresses vaccine use and implementation strategies. The guidance was issued as conditional or provisional because of the lack of evidence. Its principals are largely based on accepted practice for other vaccines. The guidance is routinely updated as new evidence becomes available. In his presentation at GRAPPA, Dr. Curtis reviewed the latest version of the guidance, which he emphasized is a guidance only and not meant to replace clinical judgment or shared decision-making with patients.

“This is a platform for you to start from as you are thinking about and discussing with your patient what might be best for him or her,” he said.
 

Concerns about impact of disease activity, treatments on effectiveness

Dr. Curtis highlighted some controversial aspects of COVID-19 vaccines, including heterogeneity of rheumatic diseases and treatment. Patients with AIIRD, including psoriatic arthritis, spondyloarthritis, RA, and lupus, are at higher risk for hospitalized COVID-19 and worse outcomes, and as such, they are prioritized for vaccination by the Centers for Disease Control and Prevention.

However, for AIIRD patients, the immune response to COVID-19 vaccination can be “blunted,” according to one study. This may be because of glucocorticoid use or high disease activity. Immunomodulatory therapies, such as methotrexate, rituximab, and abatacept, are known to diminish vaccine response in general. The evidence is less clear for tumor necrosis factor and Janus kinase inhibitors, but they are thought to have the same impact on vaccine effectiveness, Dr. Curtis said. But in these cases, if the effect of a COVID-19 vaccine drops from 90% to 70%, the benefits of vaccination still far outweighs the risk of contracting COVID-19.

“Although we don’t have strong data with clinical outcomes for autoimmune disease or inflammatory disease patients, I’ll run a hypothetical and say: ‘Look, if this vaccine starts 90%-95% effective, even if it’s only 70% effective in somebody with lupus or vasculitis or someone who is taking a higher dose of steroids, I’ll take 70% over nothing if you chose to be vaccinated,’ ” he said.

The benefit of vaccination also outweighs the potential risk of disease flare, he said. The risk is real, but to date, no studies have pointed to a significant risk of disease flare or worsening. However, there have been reported cases of myocardial infarction.

Autoimmune manifestations after vaccination vs. after infection

Researchers writing in the June 29, 2021, issue of JAMA Cardiology described case reports of acute myocarditis in 23 people who received the BNT162b2-mRNA (Pfizer-BioNTech) or mRNA-1273 (Moderna) messenger RNA (mRNA) COVID-19 vaccines. Plus, there been subsequent reports of myocarditis in other patients, wrote David K. Shay, MD, MPH, in an accompanying editorial. Dr. Shay is a member of the CDC COVID-19 Response Team.

“What do we know about this possible association between myocarditis and immunization with mRNA-based COVID-19 vaccines, and what remains unclear? Acute onset of chest pain 3-5 days after vaccine administration, usually after a second dose, is a typical feature of reported cases and suggests an immune-mediated mechanism,” he said.

The cases of myocarditis are concerning, Dr. Curtis said, but the risk is very low with relatively few cases reported among 161 million fully vaccinated people in the United States.

“Certainly, we’re not seeking to minimize that, but the risk of getting COVID and some of the downstream sequelae (autoimmune manifestations) almost certainly outweigh the risks for some of the autoimmune manifestations or worsening [condition],” he said.

A nationwide cohort study from Denmark of 58,052 patients with inflammatory rheumatic disease published in December 2020 in Rheumatology, found that patients with COVID-19 who had an inflammatory rheumatic disease were more likely to be admitted to the hospital, compared with COVID-19 patients without rheumatic disease. Patients with rheumatic disease had a higher risk of a severe COVID-19 outcome, but it was not a statistically significant difference, said Dr. Curtis, adding that the individual factors such as age and treatment currently received largely determines the risk. The strongest associations between hospitalization for COVID-19 and rheumatic disease were found among patients with RA, vasculitis, and connective tissue disease. Dr. Curtis noted that his own new study results show that risk of death from a COVID-19 infection is higher for patients who have RA or psoriatic arthritis.

There have been published case reports of patients who have developed new-onset lupus, vasculitis, Kawasaki disease, multiple sclerosis, autoimmune cytopenias, and other manifestations after a COVID-19 infection. “These authors suggest that perhaps there is a transient influence on the immune system that leads to a loss of self-tolerance to antigens,” Dr. Curtis said. “Some patients may have an underlying predisposition to autoimmunity in which infections just unmask as we sometimes see with other infections – chronic hepatitis for example.”
 

Antibody tests not recommended

In its COVID-19 guidance, the ACR, like the Food and Drug Administration, recommends health care providers not to routinely order antibody tests for IgM or IgG to assess immunity after a person has been vaccinated or to assess the need for vaccination in an unvaccinated person. More research is needed to determine if antibodies provide protection, and if so, for how long and how much. Plus, the antibody testing process is not clear cut, so ordering the wrong test is possible, Dr. Curtis said. The tests should clearly differentiate between spike proteins or nucleocapsid proteins.

“The bottom line is that you might be ordering the wrong lab test. Even if you’re ordering the right lab test, I would assert that you probably don’t know what to do with the result. I would then ask you, ‘Does it mean they are protected? Does it mean they are not protected? What are you going to do with the results?’ ” he asked.

Kevin Winthrop, MD, MPH, a specialist in infectious diseases at Oregon Health & Science University, Portland, said that, at this point, it’s too early to know what antibody tests mean. “I think it is tempting to test some people, especially patients on B-cell depletion therapy and those on mycophenolate mofetil (MMF). Outside of those two types of [disease-modifying antirheumatic drug] users, I wouldn’t be tempted to test. We don’t know how well protected they are, but we assume they are protected to some extent,” he said. “They’re probably partially protected and as such, they should take the same precautions they were taking a year ago: masking and avoidance. I think that’s just how it’s going to be for those folks for another year until we get this thing sorted out.”
 

Modifications to existing rheumatic disease therapies

In its COVID-19 vaccine guidance, the ACR issued recommendations for some common rheumatic disease therapeutics before and/or after the COVID-19 vaccine is administered. The modifications are limited to MMF, methotrexate, JAK inhibitors, subcutaneous abatacept, acetaminophen, and NSAIDs. The recommendations include: hold mycophenolate for 1 week after vaccination if disease is stable; for patients with well-controlled disease, hold methotrexate for 1 week after each of the two mRNA vaccine doses; for patients with well-controlled disease receiving the Johnson & Johnson vaccine, hold methotrexate for 2 weeks after receiving the vaccine; hold JAK inhibitors for 1 week after each dose; for abatacept subcutaneous, hold treatment for 1 week before and after the first dose; and in patients with stable disease, hold acetaminophen and NSAIDs for 24 hours before vaccination, because taking either before vaccination could blunt the vaccine response, Dr. Curtis said.

Holding medication, such as methotrexate, could risk having a flare-up of disease. One study showed the rate of disease flare-up because of withholding standard treatment may be up to 11%, compared with 5.1% in patients who did not hold treatment, he said.

“The point is, if you hold some of these therapies, whether methotrexate or tofacitinib, arthritis will get a little bit worse,” Dr. Curtis said.

A study published on the preprint server medRxiv found that immunosuppressive therapies blunted the response of SARS-CoV-2 vaccines in patients with chronic inflammatory diseases, most significantly with glucocorticoids and B-cell therapies.

“That’s what’s led to a lot of the guidance statements about holding treatments for a week or 2 for rituximab. If you’re giving it at 6-month intervals, you want to schedule the vaccine dose or series at about month 5, or a month before the next cycle,” he said.

Talking with patients about COVID-19 vaccination

In talking with patients about vaccine safety, Dr. Curtis recommends addressing a few common misperceptions. First, COVID-19 viruses were not created with a live-attenuated virus (which would be contraindicated for immunosuppressed patients). “You can put patients’ mind at ease that none of the vaccine candidates or platforms – even those that say viral vector – put patients at risk for contracting the infection. These are nonreplicating. So, it’s like you extracted the engine that would allow this virus to replicate,” he said.

Of three COVID-19 vaccinations available in the United States, is one better than the other? The ACR COVID-19 vaccine task force did not reach a consensus on safety profiles of the vaccines because, without head-to-head comparisons, it’s impossible to know, he said.

In talking with patients, review the protocol for continuing with prescribed treatment modalities before the patient receives a COVID-19 vaccine. Safety concerns and concerns about the possibility of having a disease flare-up should be addressed, he said.

With 49% of the U.S. population fully vaccinated against SARS-CoV-2, a new study highlights the degree of vaccine hesitancy among patients with rheumatic disease to get the vaccine.

Plus, there been subsequent reports of myocarditis in other patients, wrote David K. Shay, MD, MPH, in an accompanying editorial. Dr. Shay is a member of the CDC COVID-19 Response Team.

“What do we know about this possible association between myocarditis and immunization with mRNA-based COVID-19 vaccines, and what remains unclear? Acute onset of chest pain 3-5 days after vaccine administration, usually after a second dose, is a typical feature of reported cases and suggests an immune-mediated mechanism,” he said.

The cases of myocarditis are concerning, Dr. Curtis said, but the risk is very low with relatively few cases reported among 161 million fully vaccinated people in the United States.

“Certainly, we’re not seeking to minimize that, but the risk of getting COVID and some of the downstream sequelae (autoimmune manifestations) almost certainly outweigh the risks for some of the autoimmune manifestations or worsening [condition],” he said.

A nationwide cohort study from Denmark of 58,052 patients with inflammatory rheumatic disease published in December 2020 in Rheumatology, found that patients with COVID-19 who had an inflammatory rheumatic disease were more likely to be admitted to the hospital, compared with COVID-19 patients without rheumatic disease. Patients with rheumatic disease had a higher risk of a severe COVID-19 outcome, but it was not a statistically significant difference, said Dr. Curtis, adding that the individual factors such as age and treatment currently received largely determines the risk. The strongest associations between hospitalization for COVID-19 and rheumatic disease were found among patients with RA, vasculitis, and connective tissue disease. Dr. Curtis noted that his own new study results show that risk of death from a COVID-19 infection is higher for patients who have RA or psoriatic arthritis.

There have been published case reports of patients who have developed new-onset lupus, vasculitis, Kawasaki disease, multiple sclerosis, autoimmune cytopenias, and other manifestations after a COVID-19 infection. “These authors suggest that perhaps there is a transient influence on the immune system that leads to a loss of self-tolerance to antigens,” Dr. Curtis said. “Some patients may have an underlying predisposition to autoimmunity in which infections just unmask as we sometimes see with other infections – chronic hepatitis for example.”
 

Antibody tests not recommended

In its COVID-19 guidance, the ACR, like the Food and Drug Administration, recommends health care providers not to routinely order antibody tests for IgM or IgG to assess immunity after a person has been vaccinated or to assess the need for vaccination in an unvaccinated person. More research is needed to determine if antibodies provide protection, and if so, for how long and how much. Plus, the antibody testing process is not clear cut, so ordering the wrong test is possible, Dr. Curtis said. The tests should clearly differentiate between spike proteins or nucleocapsid proteins.

“The bottom line is that you might be ordering the wrong lab test. Even if you’re ordering the right lab test, I would assert that you probably don’t know what to do with the result. I would then ask you, ‘Does it mean they are protected? Does it mean they are not protected? What are you going to do with the results?’ ” he asked.

Kevin Winthrop, MD, MPH, a specialist in infectious diseases at Oregon Health & Science University, Portland, said that, at this point, it’s too early to know what antibody tests mean. “I think it is tempting to test some people, especially patients on B-cell depletion therapy and those on mycophenolate mofetil (MMF). Outside of those two types of [disease-modifying antirheumatic drug] users, I wouldn’t be tempted to test. We don’t know how well protected they are, but we assume they are protected to some extent,” he said. “They’re probably partially protected and as such, they should take the same precautions they were taking a year ago: masking and avoidance. I think that’s just how it’s going to be for those folks for another year until we get this thing sorted out.”
 

Modifications to existing rheumatic disease therapies

In its COVID-19 vaccine guidance, the ACR issued recommendations for some common rheumatic disease therapeutics before and/or after the COVID-19 vaccine is administered. The modifications are limited to MMF, methotrexate, JAK inhibitors, subcutaneous abatacept, acetaminophen, and NSAIDs. The recommendations include: hold mycophenolate for 1 week after vaccination if disease is stable; for patients with well-controlled disease, hold methotrexate for 1 week after each of the two mRNA vaccine doses; for patients with well-controlled disease receiving the Johnson & Johnson vaccine, hold methotrexate for 2 weeks after receiving the vaccine; hold JAK inhibitors for 1 week after each dose; for abatacept subcutaneous, hold treatment for 1 week before and after the first dose; and in patients with stable disease, hold acetaminophen and NSAIDs for 24 hours before vaccination, because taking either before vaccination could blunt the vaccine response, Dr. Curtis said.

Holding medication, such as methotrexate, could risk having a flare-up of disease. One study showed the rate of disease flare-up because of withholding standard treatment may be up to 11%, compared with 5.1% in patients who did not hold treatment, he said.

“The point is, if you hold some of these therapies, whether methotrexate or tofacitinib, arthritis will get a little bit worse,” Dr. Curtis said.

A study published on the preprint server medRxiv found that immunosuppressive therapies blunted the response of SARS-CoV-2 vaccines in patients with chronic inflammatory diseases, most significantly with glucocorticoids and B-cell therapies.

“That’s what’s led to a lot of the guidance statements about holding treatments for a week or 2 for rituximab. If you’re giving it at 6-month intervals, you want to schedule the vaccine dose or series at about month 5, or a month before the next cycle,” he said.

Talking with patients about COVID-19 vaccination

In talking with patients about vaccine safety, Dr. Curtis recommends addressing a few common misperceptions. First, COVID-19 viruses were not created with a live-attenuated virus (which would be contraindicated for immunosuppressed patients). “You can put patients’ mind at ease that none of the vaccine candidates or platforms – even those that say viral vector – put patients at risk for contracting the infection. These are nonreplicating. So, it’s like you extracted the engine that would allow this virus to replicate,” he said.

Of three COVID-19 vaccinations available in the United States, is one better than the other? The ACR COVID-19 vaccine task force did not reach a consensus on safety profiles of the vaccines because, without head-to-head comparisons, it’s impossible to know, he said.

In talking with patients, review the protocol for continuing with prescribed treatment modalities before the patient receives a COVID-19 vaccine. Safety concerns and concerns about the possibility of having a disease flare-up should be addressed, he said.

With 49% of the U.S. population fully vaccinated against SARS-CoV-2, a new study highlights the degree of vaccine hesitancy among patients with rheumatic disease to get the vaccine.

The international study, published in May 2021 in Rheumatology, suggests that, of 1,258 patients surveyed worldwide, approximately 40% of patients said they would decline the vaccine.

“Sometimes it’s helpful to talk through their concerns,” said Jeffrey Curtis, MD, MPH, a University of Alabama at Birmingham rheumatologist who leads the American College of Rheumatology COVID-19 vaccine task force. Dr. Curtis recently reviewed the current literature on COVID-19 vaccination in patients with rheumatic and musculoskeletal diseases (RMDs) at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.

COVID-19 vaccinations for patients with autoimmune inflammatory rheumatic disease (AIIRD) is not straightforward. The immune response can be blunted by existing treatments and disease flares can occur.

The latest version of COVID-19 vaccination guidance for patients with RMDs from the ACR addresses vaccine use and implementation strategies. The guidance was issued as conditional or provisional because of the lack of evidence. Its principals are largely based on accepted practice for other vaccines. The guidance is routinely updated as new evidence becomes available. In his presentation at GRAPPA, Dr. Curtis reviewed the latest version of the guidance, which he emphasized is a guidance only and not meant to replace clinical judgment or shared decision-making with patients.

“This is a platform for you to start from as you are thinking about and discussing with your patient what might be best for him or her,” he said.
 

Concerns about impact of disease activity, treatments on effectiveness

Dr. Curtis highlighted some controversial aspects of COVID-19 vaccines, including heterogeneity of rheumatic diseases and treatment. Patients with AIIRD, including psoriatic arthritis, spondyloarthritis, RA, and lupus, are at higher risk for hospitalized COVID-19 and worse outcomes, and as such, they are prioritized for vaccination by the Centers for Disease Control and Prevention.

However, for AIIRD patients, the immune response to COVID-19 vaccination can be “blunted,” according to one study. This may be because of glucocorticoid use or high disease activity. Immunomodulatory therapies, such as methotrexate, rituximab, and abatacept, are known to diminish vaccine response in general. The evidence is less clear for tumor necrosis factor and Janus kinase inhibitors, but they are thought to have the same impact on vaccine effectiveness, Dr. Curtis said. But in these cases, if the effect of a COVID-19 vaccine drops from 90% to 70%, the benefits of vaccination still far outweighs the risk of contracting COVID-19.

“Although we don’t have strong data with clinical outcomes for autoimmune disease or inflammatory disease patients, I’ll run a hypothetical and say: ‘Look, if this vaccine starts 90%-95% effective, even if it’s only 70% effective in somebody with lupus or vasculitis or someone who is taking a higher dose of steroids, I’ll take 70% over nothing if you chose to be vaccinated,’ ” he said.

The benefit of vaccination also outweighs the potential risk of disease flare, he said. The risk is real, but to date, no studies have pointed to a significant risk of disease flare or worsening. However, there have been reported cases of myocardial infarction.

Autoimmune manifestations after vaccination vs. after infection

Researchers writing in the June 29, 2021, issue of JAMA Cardiology described case reports of acute myocarditis in 23 people who received the BNT162b2-mRNA (Pfizer-BioNTech) or mRNA-1273 (Moderna) messenger RNA (mRNA) COVID-19 vaccines.

The relationship between adherence and benefit for those prescribed continuous positive airway pressure (CPAP) devices is clear. However, a Medicare-reimbursement rule that demands adherence blind to circumstances appears to be denying access to many low-income patients, according to an analysis delivered at the annual CHEST Health Policy and Advocacy Committee (HPAC) conference sponsored by the American College of Chest Physicians.

Over the past several years, adherence to CPAP has improved substantially following a series of studies that demonstrated the device must be used at least 4 hours per night to achieve improved outcomes. Medicare defines adherence as using the device more than 4 hours per night for 70% of nights (21 nights) during a consecutive 30-day period any time in the first 3 months of initial usage.

However, the studies that show improved adherence show a lag among those in the lowest income quartile, according to Sairam Parthasarathy, MD, FCCP, of the Center for Sleep and Circadian Sciences at the University of Arizona, Tucson.

When patients are followed for a year after being prescribed CPAP, the lag for the low-income patients is not seen immediately. Rather, adherence studies show a steady climb in adherence in all income groups initially, but “right at 90 days, there is a marked change,” according to Dr. Parthasarathy.

This change happens to coincide with Medicare policy that denies reimbursement for CPAP after 90 days if patients are not using CPAP at least 4 hours per night, which is the threshold associated with benefit.

The correlation between this policy and income disparity is “observational” rather than proven, but Dr. Parthasarathy is confident it is valid. He believes it is a prime example of a health inequity driven by poorly conceived policy.

“The 90-day rule needs to go,” he said, calling the choice of threshold “man-made.”

“This is the only disease condition for which a therapy is withheld if it is not used according to some magical threshold,” he said. “I cannot think of a more draconian policy.”

In an effort to illustrate the problem, he likened this policy to withholding insulin in a diabetes patient judged nonadherent because of a persistently elevated Hb1Ac.

At 90 days, adherence rates remain at a relatively early point in their upwards trajectory in all income groups. One year later, adherence rates are more than twice as high in the highest income relative to the lowest quartile and approaching twofold greater in quartiles 2 and 3.

“It takes time to get used to these devices,” Dr. Parthasarathy explained. Given studies demonstrating that “more is better” with CPAP, whether measured by sleep scales or quality of life, Dr. Parthasarathy advocates strategies to improve adherence, but he questioned an approach that penalizes low-income patients for a definition of nonadherence at an arbitrary point in time. He suggested it is just one example of health policies that ultimately penalize individuals with lower incomes.

“There are millions of dollars spent every year on understanding the genetics of disease, but the biggest influence on how long you live is the ZIP code of where you live,” said Dr. Parthasarathy, referring to zip codes as a surrogate for socioeconomic status.

This is not to imply, however, that genetics are irrelevant, Dr. Parthasarathy said. He pointed to data linking genetic traits that determine melanin levels and circadian rhythms. He noted one genotype associated with later bedtimes that is more commonly found in African Americans and Hispanics. This has relevance to a variety of sleep disorders and other health conditions, but it might serve as a fundamental disadvantage for children with this genotype, Dr. Parthasarathy maintained. He cited a study conducted at his center that found Hispanic children sleep on average 30 minutes less than white children (Sleep Med. 2016;18:61-66). The reason was simple. Hispanic children went to bed 30 minutes later but rose at the same time.

The later bedtimes and reduced sleep could potentially be one obstacle among many, such as the need for lower income patients to hold several jobs, that prevent these patients from becoming accustomed to CPAP at the same speed as wealthier patients, according to Dr. Parthasarathy.

The current Medicare policy that withholds CPAP on the basis of a single definition of nonadherence appears to lead directly to an inequity in treatment of sleep apnea, Dr. Parthasarathy maintained. Dr. Parthasarathy, who was a coauthor of a recently published paper on addressing disparities in sleep health (Chest. 2021;159:1232-40), described this issue as part of a larger problem of the failure to deliver health care that is sensitive to the cultural and racial differences underlying these inequities.

Kathleen Sarmiento, MD, FCCP, Director, VISN 21 Sleep Clinical Resource Hub for the San Francisco VA Health Care System, agreed. Dr. Sarmiento, a member of the CHEST Health Policy and Advocacy Committee and the moderator of the session in which Dr. Parthasarathy presented his data, said, “This type of issue is exactly what our Committee [HPAC] would like to address.”

The association between the 90-day Medicare rule for CPAP reimbursement and reduced access to this therapy among patients of lower economic status is compelling, she indicated. Within the goal of advocacy for health policies that will reduce inequities, Dr. Sarmiento explained that the committee is attempting to identify and reverse the source of these types of disparity.

“Specific rules or regulations are actionable targets to effect broader change in health care access and health care delivery,” said Dr. Sarmiento, alluding to the mission of HPAC.

Dr. Parthasarathy and Dr. Sarmiento report no relevant conflicts of interest.

The long-acting drug lenacapavir, a first-in-class capsid inhibitor, shows sustained viral suppression in a small cohort of heavily treatment-experienced patients with multidrug-resistant HIV at 26 weeks when combined with an optimized antiretroviral therapy. With regulatory approval, lenacapavir could become the only HIV-1 treatment option given every 6 months.
 

“These data support the use of lenacapavir in patients with multidrug-resistant viruses, and according to its long half-life of two subcutaneous injections per year, [it] could help reduce pill burden,” first author Jean-Michel Molina, MD, PhD, professor of infectious diseases and head of the infectious diseases department at the Saint-Louis and Lariboisière Hospitals, Paris, said in an interview.

Presenting the updated findings from the phase 2/3 CAPELLA trial at the virtual annual meeting of the International AIDS Society conference, Dr. Molina underscored the need for longer-term treatments.

“These patients with multidrug resistances are usually those who have not been fully adherent to their regimen,” he said. “Being able to provide the drug, given every 6 months subcutaneously, provides an ideal treatment for overcoming resistance and lack of adherence.”

The study showed that, after 26 weeks, 81% of heavily treatment-experienced people with HIV in a randomized cohort who were treated with a subcutaneous injection of lenacapavir (927 mg) combined with an optimized background antiretroviral regimen achieved sustained virologic suppression, with an undetectable viral load (<50 copies/mL).

In addition, the lenacapavir-treated patients had a clinically meaningful mean increase in CD4 counts of 81 cells/mcL over the 26 weeks.

The drug was well tolerated, with no drug-related serious adverse events or adverse events leading to discontinuation. The most common adverse events were injection-site reactions, which occurred in 56% of participants, with most being mild or moderate.

Importantly, four participants developed emergent resistances to lenacapavir. One was suppressed with a change in the background regimen and two others were suppressed without a change in regimen.

“We know that these mutations affect viral fitness,” Dr. Molina said in an interview. “We need more studies to assess the real impact of these mutations.”

Dr. Molina noted that a phase 2 study is already underway to evaluate how a pairing of lenacapavir with fellow investigational long-acting drug islatravir (Merck) could offset the risk of developing resistances.

Asked by an audience member whether a two-drug regimen with something like islatravir is likely to successfully prevent resistances, Dr. Molina responded that “it’s too early to know what’s going to happen with [combinations], but these first results are really encouraging when you see the very high rate of being fully suppressed after 26 weeks. The efficacy that we’ve seen after [a previous 2-week analysis] is long lasting.”
 

Lenacapavir targets multiple viral stages

Unlike other antiviral drugs that target just a single stage of viral replication, lenacapavir takes aim at multiple steps in the viral life cycle, including capsid-mediated uptake of HIV-1 proviral DNA, virus assembly and release, and capsid core formation, Dr. Molina explained.

The CAPELLA trial included participants at research centers in North America, Europe, and Asia, with a median age of 52 years; 25% were female, 38% were Black, and their mean HIV-1 RNA (viral load) was 4.17 log copies/mL.

Overall, 72 patients were divided into two cohorts of 36 patients each, including a randomized and nonrandomized cohort. Dr. Molina primarily reported results from the randomized group.

In that group, patients received either a lead-in of oral lenacapavir (600 mg on day 1 and 2 and 300 mg on day 8) or placebo, in combination with patients’ current failing drug regimens in both groups.

At day 15, all participants were switched to the investigator-selected, optimized background treatment regimen, tailored according to patients’ drug-resistance profiles, and those in the lenacapavir group received the subcutaneous injection of lenacapavir; those in the placebo group were switched to the oral lead-in, followed by subcutaneous lenacapavir every 6 months.

Combined data that included six patients from the nonrandomized cohort showed that 79% of patients had a viral load of less than 50 copies/mL at week 26. The 81% viral suppression rate represented the randomized group (29 of 36).

International AIDS Society cochair Hendrik Streeck, MD, director of the Institute of Virology and Institute for HIV Research at the University Bonn (Germany), said a twice-a-year drug could possibly have profound benefits with a reduction in daily pill burden.

“What makes this an interesting drug is that it is long acting, so one can imagine it has the potential to treat individuals such as those who are not very adherent to the antiretroviral therapy, or who can’t easily access treatment, for example in resource-limited settings,” he said in an interview. “The option to treat patients for the next months in advance could be a very important next step.”
 

Further data from CALIBRATE

Additional data on lenacapavir from the phase 2 CALIBRATE study, presented in a separate session, further showed the drug, given orally or subcutaneously in combination with oral daily emtricitabine/tenofovir alafenamide, resulted in high rates of viral suppression among 94% of 157 treatment-naive patients after 28 weeks.

Commenting on the research, session moderator Alexandra Calmy, MD, PhD, of the HIV/AIDS unit and LIPO & Metabolism group, infectious diseases division, Geneva University Hospitals, noted the study offered “interesting data indeed” – with some caveats: “Why position a new drug class in naive patients [when] we already have good options, available for a large range of various populations?”

Dr. Calmy noted that, in general, lenacapavir “would certainly be an added value with an adapted 6-monthly companion drug.”

But she raised another key issue: “When will we have data on pregnancy that would allow lenacapavir to really be a game changer worldwide?”

The study was funded by Gilead Sciences. Dr. Molina reported receiving research funding from Gilead and being on advisory boards for Gilead, Merck, ViiV, and Janssen. Dr. Calmy and Dr. Streeck reported no relevant financial relationships.

The long-acting drug lenacapavir, a first-in-class capsid inhibitor, shows sustained viral suppression in a small cohort of heavily treatment-experienced patients with multidrug-resistant HIV at 26 weeks when combined with an optimized antiretroviral therapy. With regulatory approval, lenacapavir could become the only HIV-1 treatment option given every 6 months.
 

“These data support the use of lenacapavir in patients with multidrug-resistant viruses, and according to its long half-life of two subcutaneous injections per year, [it] could help reduce pill burden,” first author Jean-Michel Molina, MD, PhD, professor of infectious diseases and head of the infectious diseases department at the Saint-Louis and Lariboisière Hospitals, Paris, said in an interview.
