MADRID, Spain – Individuals with substance use disorders are at higher risk of being infected by and dying from COVID-19 – even if they are fully vaccinated – compared with the general population. Such are the findings of a line of research led by Mexican psychiatrist Nora Volkow, MD, director of the U.S. National Institute on Drug Abuse (NIDA).

A pioneer in the use of brain imaging to investigate how substance use affects brain functions and one of Time magazine’s “Top 100 People Who Shape Our World,” she led the Inaugural Conference at the XXXI Congress of the Spanish Society of Clinical Pharmacology “Drugs and Actions During the Pandemic.” Dr. Volkow spoke about the effects that the current health crisis has had on drug use and the social challenges that arose from lockdowns. She also presented and discussed the results of studies being conducted at NIDA that “are aimed at reviewing what we’ve learned and what the consequences of COVID-19 have been with respect to substance abuse disorder.”

As Dr. Volkow pointed out, drugs affect much more than just the brain. “In particular, the heart, the lungs, the immune system – all of these are significantly harmed by substances like tobacco, alcohol, cocaine, and methamphetamine. This is why, since the beginning of the pandemic, we’ve been worried about seeing what consequences SARS-CoV-2 was going to have on users of these substances, especially in light of the great toll this disease takes on the respiratory system and the vascular system.”
 

Pulmonary ‘predisposition’ and race

Dr. Volkow and her team launched several studies to get a more thorough understanding of the link between substance abuse disorders and poor COVID-19 prognoses. One of them was based on analyses from electronic health records in the United States. The purpose was to determine COVID-19 risk and outcomes in patients based on the type of use disorder (for example, alcohol, opioid, cannabis, cocaine).

“The results showed that regardless of the drug type, all users of these substances had both a higher risk of being infected by COVID-19 and a higher death rate in comparison with the rest of the population,” said Dr. Volkow. “This surprised us, because there’s no evidence that drugs themselves make the virus more infectious. However, what the results did clearly indicate to us was that using these substances was associated with behavior that put these individuals at a greater risk for infection,” Dr. Volkow explained.

“In addition,” she continued, “using, for example, tobacco or cannabis causes inflammation in the lungs. It seems that, as a result, they end up being more vulnerable to infection by COVID. And this has consequences, above all, in terms of mortality.”

Another finding was that, among patients with substance use disorders, race had the largest effect on COVID risk. “From the very start, we saw that, compared with White individuals, Black individuals showed a much higher risk of not only getting COVID, but also dying from it,” said Dr. Volkow. “Therefore, on the one hand, our data show that drug users are more vulnerable to COVID-19 and, on the other hand, they reflect that within this group, Black individuals are even more vulnerable.”

In her presentation, Dr. Volkow drew particular attention to the impact that social surroundings have on these patients and the decisive role they played in terms of vulnerability. “It’s a very complex issue, what with the various factors at play: family, social environment. ... A person living in an at-risk situation can more easily get drugs or even prescription medication, which can also be abused.”

The psychiatrist stressed that when it comes to addictive disorders (and related questions such as prevention, treatment, and social reintegration), one of the most crucial factors has to do with the individual’s social support structures. “The studies also brought to light the role that social interaction has as an inhibitory factor with regard to drug use,” said Dr. Volkow. “And indeed, adequate adherence to treatment requires that the necessary support systems be maintained.”

In the context of the pandemic, this social aspect was also key, especially concerning the high death rate among substance use disorder patients with COVID-19. “There are very significant social determinants, such as the stigma associated with these groups – a stigma that makes these individuals more likely to hesitate to seek out treatment for diseases that may be starting to take hold, in this case COVID-19.”

On that note, Dr. Volkow emphasized the importance of treating drug addicts as though they had a chronic disease in need of treatment. “In fact, the prevalence of pathologies such as hypertension, diabetes, cancer, and dementia is much higher in these individuals than in the general population,” she said. “However, this isn’t widely known. The data reflect that not only the prevalence of these diseases, but also the severity of the symptoms, is higher, and this has a lot to do with these individuals’ reticence when it comes to reaching out for medical care. Added to that are the effects of their economic situation and other factors, such as stress (which can trigger a relapse), lack of ready access to medications, and limited access to community support or other sources of social connection.”
 

Opioids and COVID-19

As for drug use during the pandemic, Dr. Volkow provided context by mentioning that in the United States, the experts and authorities have spent two decades fighting the epidemic of opioid-related drug overdoses, which has caused many deaths. “And on top of this epidemic – one that we still haven’t been able to get control of – there’s the situation brought about by COVID-19. So, we had to see the consequences of a pandemic crossing paths with an epidemic.”

The United States’s epidemic of overdose deaths started with the use of opioid painkillers, medications which are overprescribed. Another issue that the United States faces is that many drugs are contaminated with fentanyl. This contamination has caused an increase in deaths.

“In the United States, fentanyl is everywhere,” said Dr. Volkow. “And what’s more concerning: almost a third of this fentanyl comes in pills that are sold as benzodiazepines. With this comes a high risk for overdose. In line with this, we saw overdose deaths among adolescents nearly double in 1 year, an increase which is likely related to these contaminated pills. It’s a risk that’s just below the surface. We’ve got to be vigilant, because this phenomenon is expected to eventually spread to Europe. After all, these pills are very cheap, hence the rapid increase in their use.”

To provide figures on drug use and overdose deaths since the beginning of the pandemic, Dr. Volkow referred to COVID-19 data provided by the National Center for Health Statistics (NCHS) at the U.S. Centers for Disease Control and Prevention. The data indicate that of the 70,630 drug overdose deaths that occurred in 2019, 49,860 involved opioids (whether prescribed or illicit). “And these numbers have continued to rise, so much so that the current situation can be classified as catastrophic – because this increase has been even greater during the pandemic due to the rise in the use of all drugs,” said Dr. Volkow.

Dr. Volkow referred to an NCHS study that looked at the period between September 2020 and September 2021, finding a 15.9% increase in the number of drug overdose deaths. A breakdown of these data shows that the highest percentage corresponds to deaths from “other psychostimulants,” primarily methamphetamines (35.7%). This category is followed by deaths involving synthetic opioids, mostly illicit fentanyl (25.8%), and deaths from cocaine (13.4%).

“These figures indicate that, for the first time in history, the United States had over 100,000 overdose deaths in 1 year,” said Dr. Volkow. “This is something that has never happened. We can only infer that the pandemic had a hand in making the overdose crisis even worse than it already was.”

As Dr. Volkow explained, policies related to handling overdoses and prescribing medications have been changed in the context of COVID-19. Addiction treatment consequently has been provided through a larger number of telehealth services, and measures such as greater access to treatment for comorbid conditions, expanded access to behavioral treatments, and the establishment of mental health hotlines have been undertaken.
 

Children’s cognitive development

Dr. Volkow also spoke about another of NIDA’s current subjects of research: The role that damage or compromise from drugs has on the neural circuits involved in reinforcement systems. “It’s important that we make people aware of the significance of what’s at play there, because the greatest damage that can be inflicted on the brain comes from using any type of drug during adolescence. In these cases, the likelihood of having an addictive disorder as an adult significantly increases.”

Within this framework, her team has also investigated the impact of the pandemic on the cognitive development of infants under 1 year of age. One of these studies was a pilot program in which pregnant women participated. “We found that children born during the pandemic had lower cognitive development: n = 112 versus n = 554 of those born before January 2019.”

“None of the mothers or children in the study had been infected with SARS-CoV-2,” Dr. Volkow explained. “But the results clearly reflect the negative effect of the circumstances brought about by the pandemic, especially the high level of stress, the isolation, and the lack of stimuli. Another study, currently in preprint, is based on imaging. It analyzed the impact on myelination in children not exposed to COVID-19 but born during the pandemic, compared with pre-pandemic infants. The data showed significantly reduced areas of myelin development (P < .05) in those born after 2019. And the researchers didn’t find significant differences in gestation duration or birth weight.”

The longitudinal characteristics of these studies will let us see whether a change in these individuals’ social circumstances over time also brings to light cognitive changes, even the recovery of lost or underdeveloped cognitive processes, Dr. Volkow concluded.

Dr. Volkow has disclosed no relevant financial relationships.

COVID-19 was the third-leading cause of death in the United States in 2021 for the second straight year, with only heart disease and cancer causing more deaths, the Centers for Disease Control and Prevention said April 22.

About 693,000 people died of heart disease in 2021, with 605,000 dying of cancer and 415,000 of COVID, the CDC said, citing provisional data that might be updated later.

Unintentional injuries were the fourth-leading cause of death, increasing to 219,000 in 2021 from 201,000 in 2020. Influenza and pneumonia dropped out of the top 10 leading causes of death and suicide moved into 10th place.

Overall, about 3,458,697 deaths were reported in the United States in 2021. The age-adjusted death rate was 841.6 deaths per 100,000 people, an increase of 0.7% from 2020. The 2021 death rate was the highest since 2003, the CDC said.

The overall number of COVID deaths in 2021 increased around 20% over 2020, when around 384,000 people died from the virus, the CDC said. COVID deaths in 2021 peaked for the weeks ending Jan. 16 and Sept. 11, following holiday periods.

The demographics of COVID mortality changed slightly, the CDC said in a second report.

Blacks accounted for 13.3% of COVID deaths in 2021 and Hispanics 16.5%, down several percentage points from 2020, the CDC said. Asians made up 3.1% of COVID deaths for 2021, a drop from 3.6% in 2020. White people accounted for 65.2% of COVID deaths in 2021, an increase from 59.6% in 2020.

Non-Hispanic American Indian/Alaskan Native and non-Hispanic Black or African American had the highest overall death rates for COVID, the CDC said.

Breaking the data down by age, the number of COVID deaths among people aged 75 years and older dropped to 178,000 in 2021 from around 207,000 in 2020. The numbers went up in other age groups. Among people aged 65-75, about 101,000 died of COVID in 2021, up from around 76,000 in 2020.

“The results of both studies highlight the need for greater effort to implement effective interventions,” the CDC said in a statement. “We must work to ensure equal treatment in all communities in proportion to their need for effective interventions that can prevent excess COVID-19 deaths.”

Since the pandemic began, about 991,000 people in the United States have died from COVID-related causes, the most among all nations in the world.

Since the pandemic began, about 991,000 people in the United States have died from COVID-related causes, the most among all nations in the world.

COVID-19 was the third-leading cause of death in the United States in 2021 for the second straight year, with only heart disease and cancer causing more deaths, the Centers for Disease Control and Prevention said April 22.

About 693,000 people died of heart disease in 2021, with 605,000 dying of cancer and 415,000 of COVID, the CDC said, citing provisional data that might be updated later.

Unintentional injuries were the fourth-leading cause of death, increasing to 219,000 in 2021 from 201,000 in 2020. Influenza and pneumonia dropped out of the top 10 leading causes of death and suicide moved into 10th place.

Overall, about 3,458,697 deaths were reported in the United States in 2021. The age-adjusted death rate was 841.6 deaths per 100,000 people, an increase of 0.7% from 2020. The 2021 death rate was the highest since 2003, the CDC said.

The overall number of COVID deaths in 2021 increased around 20% over 2020, when around 384,000 people died from the virus, the CDC said. COVID deaths in 2021 peaked for the weeks ending Jan. 16 and Sept. 11, following holiday periods.

The demographics of COVID mortality changed slightly, the CDC said in a second report.

Blacks accounted for 13.3% of COVID deaths in 2021 and Hispanics 16.5%, down several percentage points from 2020, the CDC said. Asians made up 3.1% of COVID deaths for 2021, a drop from 3.6% in 2020. White people accounted for 65.2% of COVID deaths in 2021, an increase from 59.6% in 2020.

Non-Hispanic American Indian/Alaskan Native and non-Hispanic Black or African American had the highest overall death rates for COVID, the CDC said.

Breaking the data down by age, the number of COVID deaths among people aged 75 years and older dropped to 178,000 in 2021 from around 207,000 in 2020. The numbers went up in other age groups. Among people aged 65-75, about 101,000 died of COVID in 2021, up from around 76,000 in 2020.

Marcus Welby, MD, was a fictitious hometown doctor featured in a TV drama with the same name that was shown on ABC from 1969 to 1976. Played by actor Robert Young, Dr. Welby treated his patients through their bouts with breast cancer, impotence, and Alzheimer’s disease.

Dr. Welby likely wouldn’t recognize the practice of medicine today, where nearly three quarters (73.9%) of physicians are employed by hospitals, health systems, or corporate entities, according to a recent report sponsored by the Physicians Advocacy Institute and prepared by consulting firm Avalere Health.

“COVID-19 drove physicians to leave private practice for employment at an even more rapid pace than we’ve seen in recent years, and these trends continued to accelerate in 2021,” Kelly Kenney, chief executive officer of Physicians Advocacy Institute, said in an announcement. “This study underscores the fact that physicians across the nation are facing severe burnout and strain. The pressures of the pandemic forced many independent physicians to make difficult decisions to sell their practices, health insurers, or other corporate entities.”

Corporate entities are defined in the report as health insurers, private equity firms, and umbrella corporate entities that own multiple physician practices.

“The pandemic has been just brutal ... for nurses and physicians who are caring for patients,” Ms. Kenney told this news organization. “Between the financial stress that the pandemic certainly had on practices, because they certainly had little revenue for a while, and then also we know that the stress that physicians have felt mentally, you can’t overstate that.”

More than half of physician practices owned by hospitals, corporate entities

The Physicians Advocacy Institute has tracked changes in physician employment consistently since 2012, said Ms. Kenney. In 2012, 25% of physicians were employed; that has jumped to nearly 74%, which means the past decade has brought a world of change to the nation’s physicians.

“These are essentially small-business people ... and they were primarily trained to care for patients,” said Ms. Kenney, referring to physicians in independent practice. Still, she understands why physicians would seek employment in the face of “the crushing kind of pressure of having to deal with 20 different payers, pay overhead, and keep the lights on [at the practice].”

According to the report, 108,700 physicians left independent practice to enter employment with hospitals or other corporate entities in the 3-year period that ended in 2021. Seventy-six percent of that shift to employed status among physicians has occurred since the start of the COVID-19 pandemic in March 2020.

From a regional perspective, the report found continued growth among employed physicians across all U.S. regions in the last half of 2020. Hospital- or corporate-owned physician practices increased between 28% and 44%, while the percentage of hospital- or corporate-employed physicians increased between 13% and 24%.

Eighty percent of physicians in the Midwest are employed by hospitals or corporations, which leads the rest of the country, per the report. That’s followed by the Northeast, the West, and the South. Overall, the number of physicians working for such entities increased in all regions.

The report revealed that physician employment by corporations such as health insurers and venture capital firms grew from 92,400 in January 2019 to 142,900 in January 2022.

Hospitals and corporate entities acquired 36,200 physician practices (representing 38% growth) between 2019 and 2021, and the majority of these moves occurred since the pandemic’s start, according to the report.

Value-based care, venture capital firms driving change

Ms. Kenney pointed to value-based care as driving much of this activity by hospitals. “We all embrace [value-based payment], because we need to get a handle on cost, and we want better quality [but] those trends tend to favor integrated systems and systems that can handle a lot of risk and populations of patients.”

Still, the moves by private equity firms and health insurers in this space is relatively new, said Ms. Kenney, who added that her organization started tracking this trend 3 years ago. She pointed to a “marked acceleration” in the trend toward employing physicians and the sale of practices in the 18 months following the pandemic’s start; nonhospital corporate entities drove that steep increase, she said.

Ms. Kenney calls for further study and “guardrails” to respond to “that force in the health care system,” referring to the acquisition of practices by entities such as private equity firms. “Are these big [health care] systems going to continue to see patients in underserved areas, rural areas, and Medicaid patients if it doesn’t make sense financially to do so?

“That’s what we’re teeing up with this research,” added Ms. Kenney. “We are providing information that starts some conversations around what we might want to think about in terms of policies to ensure that we don’t impact patients’ access to care.”

The Physicians Advocacy Institute represents more than 170,000 physicians and medical students. Avalere Health used the IQVIA OneKey database for the report. The researchers studied the 3-year period from Jan. 1, 2019, to Jan. 1, 2022.

One of the largest studies to date on myocarditis after COVID-19 vaccination confirms an increased risk with both the Pfizer and Moderna vaccines in young men and shows that the risk is higher with the Moderna than with the Pfizer vaccine.

The study also suggests for the first time that in young men 16 to 24 years of age, the risk for myocarditis after vaccination with either the Pfizer or Moderna vaccine is higher than the risk for myocarditis after COVID-19 infection.

The population-based study involved data on 23.1 million residents across four Scandinavian countries – Denmark, Finland, Norway, and Sweden – 74% of whom had received two vaccine doses and 7% of whom had received one dose.

By linking data from high-quality nationwide health registers on COVID-19 vaccination, infection rates, and myocarditis diagnoses, the researchers were able to evaluate the risk for myocarditis by vaccine product, vaccination dose number, sex, and age.

The study was published online in JAMA Cardiology.

The results confirm that the risk for myocarditis after COVID-19 mRNA vaccines is highest in young men 16 to 24 years of age after the second dose.

For men in this age group who received two doses of the same vaccine, data were compatible, with between four and seven excess myocarditis events in 28 days per 100,000 individuals after the second dose of the Pfizer vaccine, and between nine and 28 per 100,000 individuals after the second dose of the Moderna vaccine.

“This is one of the largest studies on this topic to date. The first population studies were in Israel, with 5 million individuals, and looked at just the Pfizer vaccine. We have data on 23 million people from Scandinavia that include both the Pfizer and Moderna vaccines,” senior author Rickard Ljung, MD, Swedish Medical Products Agency, told this news organization.

“We show a clearly higher risk of myocarditis after the Moderna vaccine than after the Pfizer vaccine. This has been suggested before, but our data confirm definitively that the Moderna vaccine has a higher risk of myocarditis than the Pfizer vaccine,” he added.

“In the group at highest risk of myocarditis after COVID vaccination – young men aged 16 to 24 – the Pfizer vaccine shows a five times higher risk of myocarditis versus the unvaccinated cohort, while the Moderna vaccine shows a 15 times higher risk,” Dr. Ljung noted.

After seeing these data, the Swedish regulatory authority is no longer recommending use of the Moderna vaccine for people younger than 30 years, Dr. Ljung said. Similar recommendations have been made in Norway and Finland.

The researchers report that their finding of a higher risk for myocarditis after the Moderna vaccine than after the Pfizer vaccine in young men is in line with data from the Canada, France, the United Kingdom, and the United States. But they point out that, compared with previous studies, the current study had the advantage of data analyzed according to a common protocol from four different countries and that showed similar directions of associations, despite considerable differences in previous COVID-19 infection levels and lockdown policies.

Risk higher with vaccination than infection?

For what is believed to be the first time, the Scandinavian data also suggest a higher risk for myocarditis after COVID-19 vaccination with both the Pfizer and Moderna vaccines than after COVID-19 infection in young men 16 to 24 years.

Although previous studies have shown that males in this age group have the highest risk for myocarditis after vaccination, it has always been suggested that the risk after vaccination is lower than the risk after infection. The Scandinavian data suggest otherwise for this age group.

Dr. Ljung explained that the myocarditis risk after COVID infection is very hard to study.

“It is highly dependent on the testing strategy,” he said. “For example, in the first half of 2020, the only people being tested were those admitted to hospital, so studies would have included the sickest patients and would therefore likely have found a higher rate of myocarditis. But this current Scandinavian dataset only included individuals with a positive COVID test after August 2020, reflecting a broader range of people.”

The researchers found an excess rate of myocarditis of 3.26 per 100,000 individuals within 28 days of a positive COVID-19 test among all males, and 1.37 per 100,000 individuals among males 16 to 24 years of age.

“We show that the risk of myocarditis after COVID infection is lower in younger people and higher in older people, but the opposite is true after COVID vaccination, where the risk of myocarditis is higher in younger people and lower in older people,” Dr. Ljung said.

The study was not able to look at severity of myocarditis but did record length of hospital stay, which was similar in patients who developed myocarditis after vaccination and those in the unvaccinated cohort (4 to 5 days). Deaths were rare, with no deaths in people younger than 40 years.

“I think we can say that in people aged over 40, the risk of myocarditis is greater with infection than with vaccination, but in those under 40, it is not so clear. And our data suggest that for young men aged 16 to 24 years, the risk of myocarditis after COVID vaccination with either the Pfizer or Moderna vaccine is higher than after COVID infection,” Dr. Ljung commented.

Although the Swedish regulatory agency has already stopped recommending use of Moderna vaccine in those younger than 30 years on the basis of these data, Dr. Ljung was reluctant to make any recommendations regarding the use of the Pfizer vaccine in young males, saying it was up to individual public-health agencies to makes these decisions. 

But he pointed out that the current study only looked at myocarditis, and COVID infection can result in many other complications that can lead to hospitalization and death, which needs to be taken into account when assessing the risk and benefit of vaccination.

Dr. Ljung noted that the current data only applied to the first two doses of the vaccines; data after booster injections have not been included, although the researchers are looking at that now.

What to advise patients?

In an accompanying Editor’s Note, Ann Marie Navar, MD, University of Texas Southwestern Medical Center, Dallas, who is editor of JAMA Cardiology, and Robert Bonow, MD, Northwestern University Feinberg School of Medicine, Chicago, who is deputy editor of JAMA Cardiology, try to explain how these data can inform the way health care professionals communicate with their patients about vaccination.

They point out the “good news,” that older adults who are at highest risk for COVID-19 complications appear to be at extremely low risk for vaccine-associated myocarditis.

They note that for both men and women older than 40 years, the excess number of cases of myocarditis after vaccination was fewer than two in 100,000 vaccinees across all vaccines studied, and the death toll from COVID-19 in the United States as of March was more than 200 per 100,000 population.

“Given the high rates of morbidity and mortality from COVID-19 infection in older adults and the efficacy of the vaccine in preventing severe infection and death, the benefits of immunization in those older than 40 years clearly outweigh the risks,” the editors say.

But given these data in young men, they suggest that health care professionals consider recommending the Pfizer vaccine over the Moderna vaccine for certain populations, including young men and other individuals for whom concerns about myocarditis present a barrier to immunization.

The editors also point out that although the risk for myocarditis after COVID-19 immunization is real, this low risk must be considered in the context of the overall benefit of the vaccine.

“At the individual level, immunization prevents not only COVID-19-related myocarditis but also severe disease, hospitalization, long-term complications after COVID-19 infection, and death. At the population level, immunization helps to decrease community spread, decrease the chances of new variants emerging, protect people who are immunocompromised, and ensure our health care system can continue to provide for our communities,” they conclude.

Dr. Ljung reports grants from Sanofi Aventis paid to his institution outside the submitted work and personal fees from Pfizer outside the submitted work. Dr. Navar reports personal fees from Pfizer and AstraZeneca, outside the scope of this work.

At the population level, immunization helps to decrease community spread, decrease the chances of new variants emerging, protect people who are immunocompromised, and ensure our health care system can continue to provide for our communities,” they conclude.

One of the largest studies to date on myocarditis after COVID-19 vaccination confirms an increased risk with both the Pfizer and Moderna vaccines in young men and shows that the risk is higher with the Moderna than with the Pfizer vaccine.

The study also suggests for the first time that in young men 16 to 24 years of age, the risk for myocarditis after vaccination with either the Pfizer or Moderna vaccine is higher than the risk for myocarditis after COVID-19 infection.

The population-based study involved data on 23.1 million residents across four Scandinavian countries – Denmark, Finland, Norway, and Sweden – 74% of whom had received two vaccine doses and 7% of whom had received one dose.

By linking data from high-quality nationwide health registers on COVID-19 vaccination, infection rates, and myocarditis diagnoses, the researchers were able to evaluate the risk for myocarditis by vaccine product, vaccination dose number, sex, and age.

The study was published online in JAMA Cardiology.

The results confirm that the risk for myocarditis after COVID-19 mRNA vaccines is highest in young men 16 to 24 years of age after the second dose.

For men in this age group who received two doses of the same vaccine, data were compatible, with between four and seven excess myocarditis events in 28 days per 100,000 individuals after the second dose of the Pfizer vaccine, and between nine and 28 per 100,000 individuals after the second dose of the Moderna vaccine.

“This is one of the largest studies on this topic to date. The first population studies were in Israel, with 5 million individuals, and looked at just the Pfizer vaccine. We have data on 23 million people from Scandinavia that include both the Pfizer and Moderna vaccines,” senior author Rickard Ljung, MD, Swedish Medical Products Agency, told this news organization.

“We show a clearly higher risk of myocarditis after the Moderna vaccine than after the Pfizer vaccine. This has been suggested before, but our data confirm definitively that the Moderna vaccine has a higher risk of myocarditis than the Pfizer vaccine,” he added.

“In the group at highest risk of myocarditis after COVID vaccination – young men aged 16 to 24 – the Pfizer vaccine shows a five times higher risk of myocarditis versus the unvaccinated cohort, while the Moderna vaccine shows a 15 times higher risk,” Dr. Ljung noted.

After seeing these data, the Swedish regulatory authority is no longer recommending use of the Moderna vaccine for people younger than 30 years, Dr. Ljung said. Similar recommendations have been made in Norway and Finland.

The researchers report that their finding of a higher risk for myocarditis after the Moderna vaccine than after the Pfizer vaccine in young men is in line with data from the Canada, France, the United Kingdom, and the United States. But they point out that, compared with previous studies, the current study had the advantage of data analyzed according to a common protocol from four different countries and that showed similar directions of associations, despite considerable differences in previous COVID-19 infection levels and lockdown policies.

Risk higher with vaccination than infection?

For what is believed to be the first time, the Scandinavian data also suggest a higher risk for myocarditis after COVID-19 vaccination with both the Pfizer and Moderna vaccines than after COVID-19 infection in young men 16 to 24 years.

Although previous studies have shown that males in this age group have the highest risk for myocarditis after vaccination, it has always been suggested that the risk after vaccination is lower than the risk after infection. The Scandinavian data suggest otherwise for this age group.

Dr. Ljung explained that the myocarditis risk after COVID infection is very hard to study.

“It is highly dependent on the testing strategy,” he said. “For example, in the first half of 2020, the only people being tested were those admitted to hospital, so studies would have included the sickest patients and would therefore likely have found a higher rate of myocarditis. But this current Scandinavian dataset only included individuals with a positive COVID test after August 2020, reflecting a broader range of people.”

The researchers found an excess rate of myocarditis of 3.26 per 100,000 individuals within 28 days of a positive COVID-19 test among all males, and 1.37 per 100,000 individuals among males 16 to 24 years of age.

“We show that the risk of myocarditis after COVID infection is lower in younger people and higher in older people, but the opposite is true after COVID vaccination, where the risk of myocarditis is higher in younger people and lower in older people,” Dr. Ljung said.

The study was not able to look at severity of myocarditis but did record length of hospital stay, which was similar in patients who developed myocarditis after vaccination and those in the unvaccinated cohort (4 to 5 days). Deaths were rare, with no deaths in people younger than 40 years.

“I think we can say that in people aged over 40, the risk of myocarditis is greater with infection than with vaccination, but in those under 40, it is not so clear. And our data suggest that for young men aged 16 to 24 years, the risk of myocarditis after COVID vaccination with either the Pfizer or Moderna vaccine is higher than after COVID infection,” Dr. Ljung commented.

Although the Swedish regulatory agency has already stopped recommending use of Moderna vaccine in those younger than 30 years on the basis of these data, Dr. Ljung was reluctant to make any recommendations regarding the use of the Pfizer vaccine in young males, saying it was up to individual public-health agencies to makes these decisions. 

But he pointed out that the current study only looked at myocarditis, and COVID infection can result in many other complications that can lead to hospitalization and death, which needs to be taken into account when assessing the risk and benefit of vaccination.

Dr. Ljung noted that the current data only applied to the first two doses of the vaccines; data after booster injections have not been included, although the researchers are looking at that now.

What to advise patients?

In an accompanying Editor’s Note, Ann Marie Navar, MD, University of Texas Southwestern Medical Center, Dallas, who is editor of JAMA Cardiology, and Robert Bonow, MD, Northwestern University Feinberg School of Medicine, Chicago, who is deputy editor of JAMA Cardiology, try to explain how these data can inform the way health care professionals communicate with their patients about vaccination.

They point out the “good news,” that older adults who are at highest risk for COVID-19 complications appear to be at extremely low risk for vaccine-associated myocarditis.

They note that for both men and women older than 40 years, the excess number of cases of myocarditis after vaccination was fewer than two in 100,000 vaccinees across all vaccines studied, and the death toll from COVID-19 in the United States as of March was more than 200 per 100,000 population.

“Given the high rates of morbidity and mortality from COVID-19 infection in older adults and the efficacy of the vaccine in preventing severe infection and death, the benefits of immunization in those older than 40 years clearly outweigh the risks,” the editors say.

But given these data in young men, they suggest that health care professionals consider recommending the Pfizer vaccine over the Moderna vaccine for certain populations, including young men and other individuals for whom concerns about myocarditis present a barrier to immunization.

The editors also point out that although the risk for myocarditis after COVID-19 immunization is real, this low risk must be considered in the context of the overall benefit of the vaccine.

“At the individual level, immunization prevents not only COVID-19-related myocarditis but also severe disease, hospitalization, long-term complications after COVID-19 infection, and death. At the population level, immunization helps to decrease community spread, decrease the chances of new variants emerging, protect people who are immunocompromised, and ensure our health care system can continue to provide for our communities,” they conclude.

More than 50% of obese adolescents met criteria for depression, which also was associated with several components of metabolic syndrome, based on data from 160 individuals.

Previous research shows that the metabolic consequences of obesity are worsened with the coexistence of depression in adults, but a similar relationship in obese adolescents has not been explored, according to Nisha Gupta, a medical student at the University of Texas Health Science Center, Houston, and colleagues.

“This relationship is explained by an overactive stress response and adoption of unhealthy lifestyle habits,” both of which increased during the COVID-19 pandemic, the researchers noted in their abstract.

In a study presented at the Pediatric Academic Societies annual meeting, the researchers reviewed data from 160 obese adolescents seen at a pediatric weight management clinic between July 1, 2018, and Dec. 3, 2021. The data included anthropometric, clinical, and laboratory information. Depression was assessed using the Patient Health Questionnaire–9 (PHQ-9). The goal of the study was to compare the prevalence of metabolic syndrome components in obese youth with and without diagnosed depression.

Overall, 46% of the patients had PHQ-9 scores less than 5, which was defined as no clinically significant depression. A total of 26% had current or prior diagnoses of depression, and 25% met the criteria for moderate to severe depression, with PHQ-9 scores of 10 or higher. Notably, 18% of individuals with no prior history of depression met criteria for moderate to severe depression, the researchers wrote.

Teens who reported daytime fatigue or trouble sleeping, and those who reported eating out seven or more times a week had higher scores than those without these reports.

In laboratory analyses, higher PHQ-9 scores were significantly associated with increasing weight, body mass index, body fat percentage, diastolic blood pressure, and fasting blood insulin (P < .02 for all).

The study findings were limited by the relatively small sample size, the researchers noted. However, the results suggest that depression is common, but often underdiagnosed in obese adolescents, and depression screening should be part of obesity management.
 

Study highlights need to screen

The current study is important because of the overall increase in obesity in the United States, which extends to children and teens, Tim Joos, MD, a Seattle-based clinician with a combination internal medicine/pediatrics practice, said in an interview.

“With skyrocketing rates of obesity among children and teens over the last decades, we are seeing more ‘adult’ diseases seep into the younger ages, including type 2 diabetes, high blood pressure and now, depression,” he said.

“The results are a wake-up call for the need for better system-wide prevention and management of obesity in adolescents and the importance of screening and managing depression in obese teenagers,” he emphasized.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Joos had no financial conflicts to disclose and serves on the editorial advisory board of Pediatric News.

Both a standard and culturally tailored online intervention improved insomnia symptoms in Black women, compared with a non-Internet patient education intervention.

Data from previous studies suggest that women are up to 40% more likely to experience insomnia disorder compared with men, Eric S. Zhou, PhD, of Harvard Medical School, Boston, and colleagues wrote. The risk is even higher among Black women, but research on tailored treatments for this particular population has been limited.

In their study, published in JAMA Psychiatry, the researchers recruited women with elevated insomnia symptoms who were enrolled in the Black Women’s Health Study, an ongoing national, longitudinal research cohort in the United States. Participants were recruited between October 2019 and June 2020.The participants were randomized to an Internet-delivered behavior intervention (108 women), a stakeholder-informed Internet intervention tailored to Black women (110 women), or non-Internet patient education about sleep (115 women).

The Internet intervention, known as Sleep Healthy Using the Internet (SHUTi), was a 6-session program lasting 45-60 minutes per session and delivered over 6-9 weeks. The program included core elements of cognitive behavioral therapy and took into account information provided by patients about their baseline sleep function, treatment adherence, and sleep progress.

The tailored version of SHUTi for Black women (SHUTi-BWHS) was similar, but included Black actors for video vignettes and the inclusion of content about the cultural and social contexts in which insomnia often occurs for Black women, such while managing neighborhood noise and or living in crowded environments.

A third group received standard patient education material about sleep through a noninteractive website, and served as the control group.

The primary outcome of insomnia severity was measured using the Insomnia Severity Index (ISI), a 0- to 28-point scale. Scores for the ISI are based on responses to seven questions, including some that ask participants to rate the severity of their insomnia symptoms.

Clinically significant improvement in insomnia was defined as a reduction in score of more than 7 points. Patients were assessed at baseline, at 9 weeks, and again at approximately 6 months.
 

Significantly greater reductions in insomnia severity seen in intervention groups vs. control group

Overall, women randomized to SHUTi or SHUTi-BWHS) reported a significantly greater reduction in insomnia symptoms from baseline to 6 months, compared with the control group (P < .001), with ISI score decreases of 10.0, 9.3, and 3.6, respectively. No statistically significant differences in ISI score changes appeared between the between the SHUTi-BWHS and SHUTi groups.

Also, significantly more women in the SHUTi-BWHS group than in the SHUTi group completed the intervention (78.2% vs. 64.8%).

Treatment response was similar between the SHUTI-BWHS and SHUTi groups; 47.3% and 46.3%, respectively, had a decrease in ISI score of more than 7 points. In addition, 37% of women in the SHUTi-BWHS and 38% of women in the SHUTi groups reached ISI scores of less than 8 points, defined as full resolution of insomnia, by the last follow-up visit.

Both the SHUTi and SHUTi-BWHS interventions had dramatic effects on insomnia, but the increased number of women who completed the intervention in the SHUTi-BWHS group supports the value of tailored intervention, the researchers noted. “Similar to prior SHUTi trials, there was a direct association between the participant’s level of intervention engagement and their improvement in sleep.”

The average age of the participants was 60 years, 62% were single, and 44% had a graduate degree or higher. Approximately 5% were being actively treated for sleep apnea.

The study findings were limited by several factors including the relatively high socioeconomic status of the study participants, lack of data on medical mistrust, and inability to detect smaller differences between SHUTi and SHUTi-BWHS, the researchers noted.

 

Choose Internet-based CBT first for insomnia

“This was an excellent paper that sought to see the relative efficacy of standard version of Internet-delivered CBT-I [cognitive-behavioral therapy for insomnia] versus a culturally tailored version for Black women,” said Neil Skolnik, MD, professor of family and community medicine at Thomas Jefferson University, Philadelphia, in an interview. “The trial confirmed that, compared with sleep education, which was used as the control, Internet-delivered CBT-I is effective in the treatment of insomnia.”

“These results demonstrate two important things,” said Dr. Skolnik. “The most important is that Internet-delivered CBT-I works, and since it is both safe and effective, should be the first-line therapy for patients who want treatment for insomnia.”

Secondly, “the fact that more people completed culturally tailored versions suggests that, when culturally tailored versions are available, their use is preferable, as it might facilitate a higher proportion of patients being successful in their insomnia treatment,” he added.

Extraverts and individuals who are disciplined are less likely to experience cognitive decline later in life, whereas those with neuroticism have an increased risk for cognitive dysfunction, new research shows.

Investigators analyzed data from almost 2,000 individuals enrolled in the Rush Memory and Aging Project (MAP) – a longitudinal study of older adults living in the greater Chicago metropolitan region and northeastern Illinois – with recruitment that began in 1997 and continues through today. Participants received a personality assessment as well as annual assessments of their cognitive abilities.

Those with high scores on measures of conscientiousness were significantly less likely to progress from normal cognition to mild cognitive impairment (MCI) during the study. In fact, scoring an extra 1 standard deviation on the conscientiousness scale was associated with a 22% lower risk of transitioning from no cognitive impairment (NCI) to MCI. On the other hand, scoring an additional 1 SD on a neuroticism scale was associated with a 12% increased risk of transitioning to MCI.

Participants who scored high on extraversion, as well as those who scored high on conscientiousness or low on neuroticism, tended to maintain normal cognitive functioning longer than other participants.

“Personality traits reflect relatively enduring patterns of thinking and behaving, which may cumulatively affect engagement in healthy and unhealthy behaviors and thought patterns across the lifespan,” lead author Tomiko Yoneda, PhD, a postdoctoral researcher in the department of medical social sciences, Northwestern University, Chicago, said in an interview.

“The accumulation of lifelong experiences may then contribute to susceptibility of particular diseases or disorders, such as mild cognitive impairment, or contribute to individual differences in the ability to withstand age-related neurological changes,” she added.

The study was published online in the Journal of Personality and Social Psychology.
 

Competing risk factors

Personality traits “reflect an individual’s persistent patterns of thinking, feeling, and behaving,” Dr. Yoneda said.

“For example, conscientiousness is characterized by competence, dutifulness, and self-discipline, while neuroticism is characterized by anxiety, depressive symptoms, and emotional instability. Likewise, individuals high in extraversion tend to be enthusiastic, gregarious, talkative, and assertive,” she added.

Previous research “suggests that low conscientiousness and high neuroticism are associated with an increased risk of cognitive impairment,” she continued. However, “there is also an increased risk of death in older adulthood – in other words, these outcomes are ‘competing risk factors.’”

Dr. Yoneda said her team wanted to “examine the impact of personality traits on the simultaneous risk of transitioning to mild cognitive impairment, dementia, and death.”  

For the study, the researchers analyzed data from 1,954 participants in MAP (mean age at baseline 80 years, 73.7% female, 86.8% White), who received a personality assessment and annual assessments of their cognitive abilities.

To assess personality traits – in particular, conscientiousness, neuroticism, and extraversion – the researchers used the NEO Five Factor Inventory (NEO-FFI). They also used multistate survival modeling to examine the potential association between these traits and transitions from one cognitive status category to another (NCI, MCI, and dementia) and to death.
 

Cognitive healthspan

By the end of the study, over half of the sample (54%) had died.

Most transitions showed “relative stability in cognitive status across measurement occasions.”

• NCI to NCI (n = 7,368)
• MCI to MCI (n = 1,244)
• Dementia to dementia (n = 876)

There were 725 “backward transitions” from MCI to NCI, “which may reflect improvement or within-person variability in cognitive functioning, or learning effects,” the authors note.

There were only 114 “backward transitions” from dementia to MCI and only 12 from dementia to NCI, “suggesting that improvement in cognitive status was relatively rare, particularly once an individual progresses to dementia.”

After adjusting for demographics, depressive symptoms, and apolipoprotein (APOE) ε4 allele, the researchers found that personality traits were the most important factors in the transition from NCI to MCI.

Higher conscientiousness was associated with a decreased risk of transitioning from NCI to MCI (hazard ratio, 0.78; 95% confidence interval, 0.72-0.85). Conversely, higher neuroticism was associated with an increased risk of transitioning from NCI to MCI (HR, 1.12; 95% CI, 1.04-1.21) and a significantly decreased likelihood of transition back from MCI to NCI (HR, 0.90; 95% CI, 0.81-1.00).

Scoring ~6 points on a conscientiousness scale ranging from 0-48 (that is, 1 SD on the scale) was significantly associated with ~22% lower risk of transitioning forward from NCI to MCI, while scoring ~7 more points on a neuroticism scale (1 SD) was significantly associated with ~12% higher risk of transitioning from NCI to MCI.

Higher extraversion was associated with an increased likelihood of transitioning from MCI back to NCI (HR, 1.12; 95% CI, 1.03-1.22), and although extraversion was not associated with a longer total lifespan, participants who scored high on extraversion, as well as those who scored low on conscientiousness or low on neuroticism, maintained normal cognitive function longer than other participants.

“Our results suggest that high conscientiousness and low neuroticism may protect individuals against mild cognitive impairment,” said Dr. Yoneda.

Importantly, individuals who were either higher in conscientiousness, higher in extraversion, or lower in neuroticism had more years of “cognitive healthspan,” meaning more years without cognitive impairment,” she added.

In addition, “individuals lower in neuroticism and higher in extraversion were more likely to recover after receiving an MCI diagnosis, suggesting that these traits may be protective even after an individual starts to progress to dementia,” she said.

The authors note that the study focused on only three of the Big Five personality traits, while the other 2 – openness to experience and agreeableness – may also be associated with cognitive aging processes and mortality.

Nevertheless, given the current results, alongside extensive research in the personality field, aiming to increase conscientiousness through persistent behavioral change is one potential strategy for promoting healthy cognitive aging, Dr. Yoneda said.
 

‘Invaluable window’

In a comment, Brent Roberts, PhD, professor of psychology, University of Illinois Urbana-Champaign, said the study provides an “invaluable window into how personality affects the process of decline and either accelerates it, as in the role of neuroticism, or decelerates it, as in the role of conscientiousness.”

“I think the most fascinating finding was the fact that extraversion was related to transitioning from MCI back to NCI. These types of transitions have simply not been part of prior research, and it provides utterly unique insights and opportunities for interventions that may actually help people recover from a decline,” said Dr. Roberts, who was not involved in the research.

Claire Sexton, DPhil, Alzheimer’s Association director of scientific programs and outreach, called the paper “novel” because it investigated the transitions between normal cognition and mild impairment and between mild impairment and dementia.

Dr. Sexton, who was associated with this research team, cautioned that is it observational, “so it can illuminate associations or correlations, but not causes. As a result, we can’t say for sure what the mechanisms are behind these potential connections between personality and cognition, and more research is needed.”

The research was supported by the Alzheimer Society Research Program, Social Sciences and Humanities Research Council, and the National Institute on Aging of the National Institutes of Health. Dr. Yoneda and co-authors, Dr. Roberts, and Dr. Sexton have disclosed no relevant financial relationships.

Extraverts and individuals who are disciplined are less likely to experience cognitive decline later in life, whereas those with neuroticism have an increased risk for cognitive dysfunction, new research shows.

Investigators analyzed data from almost 2,000 individuals enrolled in the Rush Memory and Aging Project (MAP) – a longitudinal study of older adults living in the greater Chicago metropolitan region and northeastern Illinois – with recruitment that began in 1997 and continues through today. Participants received a personality assessment as well as annual assessments of their cognitive abilities.

Those with high scores on measures of conscientiousness were significantly less likely to progress from normal cognition to mild cognitive impairment (MCI) during the study. In fact, scoring an extra 1 standard deviation on the conscientiousness scale was associated with a 22% lower risk of transitioning from no cognitive impairment (NCI) to MCI. On the other hand, scoring an additional 1 SD on a neuroticism scale was associated with a 12% increased risk of transitioning to MCI.

Participants who scored high on extraversion, as well as those who scored high on conscientiousness or low on neuroticism, tended to maintain normal cognitive functioning longer than other participants.

“Personality traits reflect relatively enduring patterns of thinking and behaving, which may cumulatively affect engagement in healthy and unhealthy behaviors and thought patterns across the lifespan,” lead author Tomiko Yoneda, PhD, a postdoctoral researcher in the department of medical social sciences, Northwestern University, Chicago, said in an interview.

“The accumulation of lifelong experiences may then contribute to susceptibility of particular diseases or disorders, such as mild cognitive impairment, or contribute to individual differences in the ability to withstand age-related neurological changes,” she added.

The study was published online in the Journal of Personality and Social Psychology.
 

Competing risk factors

Personality traits “reflect an individual’s persistent patterns of thinking, feeling, and behaving,” Dr. Yoneda said.

“For example, conscientiousness is characterized by competence, dutifulness, and self-discipline, while neuroticism is characterized by anxiety, depressive symptoms, and emotional instability. Likewise, individuals high in extraversion tend to be enthusiastic, gregarious, talkative, and assertive,” she added.

Disulfiram, a U.S. Food and Drug Administration–approved medication for the treatment of chronic alcohol dependence, shows promise as a potential anxiolytic, early research suggests.

Japanese researchers, headed by Akiyoshi Saitoh, PhD, professor in the department of pharmacy, Tokyo University of Science, compared the reactions of mice that received a classic anxiolytic agent (diazepam) to those that received disulfiram while performing a maze task and found comparable reductions in anxiety in both groups of mice.

Moreover, unlike diazepam, disulfiram caused no sedation, amnesia, or impairments in coordination.

“These results indicate that disulfiram can be used safely by elderly patients suffering from anxiety and insomnia and has the potential to become a breakthrough psychotropic drug,” Dr. Saitoh said in a press release.

The study was published online in Frontiers in Pharmacology.
 

Inhibitory function

Disulfiram inhibits the enzyme aldehyde dehydrogenase (ALDH), which is responsible for alcohol metabolism. Recent research suggests that disulfiram may have broader inhibitory functions.

In particular, it inhibits the cytoplasmic protein FROUNT, preventing it from interacting with two chemokine receptors (CCR2 and CCRs) that are involved in cellular signaling pathways and are associated with regulating behaviors, including anxiety, in rodents, the authors write.

“Although the functions of FROUNT-chemokines signaling in the immune system are well documented, the potential role of CNS-expressed FROUNT chemokine–related molecules as neuromodulators remains largely unknown,” they write.

The researchers had been conducting preclinical research on the secondary pharmacologic properties of disulfiram and “coincidentally discovered” its “anxiolytic-like effects.” They investigated these effects further because currently used anxiolytics – i.e., benzodiazepines – have unwanted side effects.

The researchers utilized an elevated plus-maze (EPM) test to investigate the effects of disulfiram in mice. The EPM apparatus consists of four arms set in a cross pattern and are connected to a central square. Of these, two arms are protected by vertical boundaries, while the other two have unprotected edges. Typically, mice with anxiety prefer to spend time in the closed arms. The mice also underwent other tests of coordination and the ability to navigate a Y-maze.

Some mice received disulfiram, others received a benzodiazepine, and others received merely a “vehicle,” which served as a control.

Disulfiram “significantly and dose-dependently” increased the time spent in the open arms of the EPM, compared with the vehicle-treated group, at 30 minutes after administration (F [3, 30] = 16.64; P < .0001), suggesting less anxiety. The finding was confirmed by a Bonferroni analysis that showed a significant effect of disulfiram, compared with the vehicle-treated group, at all three doses (20 mg/kg: t = 0.9894; P > .05; 40 mg/kg: t = 3.863; P < .01; 80 mg/kg: t = 6.417; P < .001).

A Student’s t-test analysis showed that diazepam likewise had a significant effect, compared to the vehicle (t = 5.038; P < .001).

Disulfiram also “significantly and dose-dependently” increased the percentage of open-arm entries (F [3, 30] = 14.24; P < .0001). The Bonferroni analysis showed this effect at all three doses (20 mg/kg: t = 0.3999; P > .05; 40 mg/kg: t = 2.693; P > .05; 80 mg/kg: t = 5.864; P < .001).

Diazepam similarly showed a significant effect, compared to the vehicle condition (t = 3.733; P < .005).

In particular, the 40 mg/kg dose of disulfiram significantly increased the percentage of time spent in the open arms at 15, 30, and 60 minutes after administration, with the peak effect occurring at 30 minutes.

The researchers examined the effect of cyanamide, another ALDH inhibitor, on the anxiety behaviors of mice and found no effect on the number of open-arm entries or percentage of time the mice spent in the open arm, compared with the vehicle condition.

In contrast to diazepam, disulfiram had no effect on the amount of spontaneous locomotor activity, time spent on the rotarod, or activity on the Y-maze test displayed by the mice, “suggesting that there were no apparent sedative effects at the dosages used.” Moreover, unlike the mice treated with diazepam, there were no increases in the number of falls the mice experienced on the rotarod.

Glutamate levels in the prelimbic-prefrontal cortex (PL-PFC) “play an important role in the development of anxiety-like behavior in mice,” the authors state. Disulfiram “significantly and completely attenuated increased extracellular glutamate levels in the PL-PFC during stress exposure” on the EPM.

“We propose that DSF inhibits FROUNT protein and the chemokine signaling pathways under its influence, which may suppress presynaptic glutamatergic transmission in the brain,” said Dr. Saitoh. “This, in turn, attenuates the levels of glutamate in the brain, reducing overall anxiety.”
 

Humanity’s most common affliction

Commenting for this news organization, Roger McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, and head of the mood disorders psychopharmacology unit, noted that there is a “renewed interest in psychiatry in excitatory and inhibitory balance – for example, ketamine represents a treatment that facilitates excitatory activity, while neurosteroids are candidate medicines now for inhibitory activity.”

Dr. McIntyre, who is the chairman and executive director of the Brain and Cognitive Discover Foundation, Toronto, and was not involved with the study, said it is believed “that the excitatory-inhibitory balance may be relevant to brain health and disease.”

Dr. McIntyre also pointed out that the study “highlights not only the repurposing of a well-known medicine but also exploit[s] the potential brain therapeutic effects of immune targets that indirectly affect inhibitory systems, resulting in potentially a safer treatment for anxiety – the most common affliction of humanity.”

Also commenting for this article, Wilfrid Noel Raby, MD, PhD, a psychiatrist in private practice in Teaneck, N.J., called disulfiram “grossly underused for alcohol use disorders and even more so when people use alcohol and cocaine.”

Dr. Raby, who was not involved with the study, has found that patients withdrawing from cocaine, cannabis, or stimulants “can respond very well to disulfiram [not only] in terms of their cravings but also in terms of mood stabilization and anxiolysis.”

He has also found that for patients with bipolar disorder or attention-deficit/hyperactivity disorder with depression disulfiram and low-dose lithium “can provide anxiolysis and mood stabilization, especially if a rapid effect is required, usually within a week.”

However, Dr. Raby cautioned that “it is probably not advisable to maintain patients on disulfiram for periods long than 3 months consecutively because there is a risk of neuropathy and hepatopathology that are not common but are seen often enough.” He usually interrupts treatment for a month and then resumes if necessary.

The research was partially supported by the Tsukuba Clinical Research and Development Organization from the Japan Agency for Medical Research and Development. The authors and Dr. Raby have disclosed no relevant financial relationships. Dr. McIntyre reports receiving research grant support from CIHR/GACD/National Natural Science Foundation of China; speaker/consultation fees from Lundbeck, Janssen, Alkermes, Mitsubishi Tanabe, Purdue, Pfizer, Otsuka, Takeda, Neurocrine, Sunovion, Bausch Health, Axsome, Novo Nordisk, Kris, Sanofi, Eisai, Intra-Cellular, NewBridge Pharmaceuticals, AbbVie, and Atai Life Sciences.

Dr. Raby, who was not involved with the study, has found that patients withdrawing from cocaine, cannabis, or stimulants “can respond very well to disulfiram [not only] in terms of their cravings but also in terms of mood stabilization and anxiolysis.”

He has also found that for patients with bipolar disorder or attention-deficit/hyperactivity disorder with depression disulfiram and low-dose lithium “can provide anxiolysis and mood stabilization, especially if a rapid effect is required, usually within a week.”

However, Dr. Raby cautioned that “it is probably not advisable to maintain patients on disulfiram for periods long than 3 months consecutively because there is a risk of neuropathy and hepatopathology that are not common but are seen often enough.” He usually interrupts treatment for a month and then resumes if necessary.

Disulfiram, a U.S. Food and Drug Administration–approved medication for the treatment of chronic alcohol dependence, shows promise as a potential anxiolytic, early research suggests.

Japanese researchers, headed by Akiyoshi Saitoh, PhD, professor in the department of pharmacy, Tokyo University of Science, compared the reactions of mice that received a classic anxiolytic agent (diazepam) to those that received disulfiram while performing a maze task and found comparable reductions in anxiety in both groups of mice.

Moreover, unlike diazepam, disulfiram caused no sedation, amnesia, or impairments in coordination.

“These results indicate that disulfiram can be used safely by elderly patients suffering from anxiety and insomnia and has the potential to become a breakthrough psychotropic drug,” Dr. Saitoh said in a press release.

The study was published online in Frontiers in Pharmacology.
 

Inhibitory function

Disulfiram inhibits the enzyme aldehyde dehydrogenase (ALDH), which is responsible for alcohol metabolism. Recent research suggests that disulfiram may have broader inhibitory functions.

In particular, it inhibits the cytoplasmic protein FROUNT, preventing it from interacting with two chemokine receptors (CCR2 and CCRs) that are involved in cellular signaling pathways and are associated with regulating behaviors, including anxiety, in rodents, the authors write.

“Although the functions of FROUNT-chemokines signaling in the immune system are well documented, the potential role of CNS-expressed FROUNT chemokine–related molecules as neuromodulators remains largely unknown,” they write.

The researchers had been conducting preclinical research on the secondary pharmacologic properties of disulfiram and “coincidentally discovered” its “anxiolytic-like effects.” They investigated these effects further because currently used anxiolytics – i.e., benzodiazepines – have unwanted side effects.

The researchers utilized an elevated plus-maze (EPM) test to investigate the effects of disulfiram in mice. The EPM apparatus consists of four arms set in a cross pattern and are connected to a central square. Of these, two arms are protected by vertical boundaries, while the other two have unprotected edges. Typically, mice with anxiety prefer to spend time in the closed arms. The mice also underwent other tests of coordination and the ability to navigate a Y-maze.

Some mice received disulfiram, others received a benzodiazepine, and others received merely a “vehicle,” which served as a control.

Disulfiram “significantly and dose-dependently” increased the time spent in the open arms of the EPM, compared with the vehicle-treated group, at 30 minutes after administration (F [3, 30] = 16.64; P < .0001), suggesting less anxiety. The finding was confirmed by a Bonferroni analysis that showed a significant effect of disulfiram, compared with the vehicle-treated group, at all three doses (20 mg/kg: t = 0.9894; P > .05; 40 mg/kg: t = 3.863; P < .01; 80 mg/kg: t = 6.417; P < .001).

A Student’s t-test analysis showed that diazepam likewise had a significant effect, compared to the vehicle (t = 5.038; P < .001).

Disulfiram also “significantly and dose-dependently” increased the percentage of open-arm entries (F [3, 30] = 14.24; P < .0001). The Bonferroni analysis showed this effect at all three doses (20 mg/kg: t = 0.3999; P > .05; 40 mg/kg: t = 2.693; P > .05; 80 mg/kg: t = 5.864; P < .001).

Diazepam similarly showed a significant effect, compared to the vehicle condition (t = 3.733; P < .005).

In particular, the 40 mg/kg dose of disulfiram significantly increased the percentage of time spent in the open arms at 15, 30, and 60 minutes after administration, with the peak effect occurring at 30 minutes.

The researchers examined the effect of cyanamide, another ALDH inhibitor, on the anxiety behaviors of mice and found no effect on the number of open-arm entries or percentage of time the mice spent in the open arm, compared with the vehicle condition.

In contrast to diazepam, disulfiram had no effect on the amount of spontaneous locomotor activity, time spent on the rotarod, or activity on the Y-maze test displayed by the mice, “suggesting that there were no apparent sedative effects at the dosages used.” Moreover, unlike the mice treated with diazepam, there were no increases in the number of falls the mice experienced on the rotarod.

Glutamate levels in the prelimbic-prefrontal cortex (PL-PFC) “play an important role in the development of anxiety-like behavior in mice,” the authors state. Disulfiram “significantly and completely attenuated increased extracellular glutamate levels in the PL-PFC during stress exposure” on the EPM.

“We propose that DSF inhibits FROUNT protein and the chemokine signaling pathways under its influence, which may suppress presynaptic glutamatergic transmission in the brain,” said Dr. Saitoh. “This, in turn, attenuates the levels of glutamate in the brain, reducing overall anxiety.”
 

Humanity’s most common affliction

Commenting for this news organization, Roger McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, and head of the mood disorders psychopharmacology unit, noted that there is a “renewed interest in psychiatry in excitatory and inhibitory balance – for example, ketamine represents a treatment that facilitates excitatory activity, while neurosteroids are candidate medicines now for inhibitory activity.”

Dr. McIntyre, who is the chairman and executive director of the Brain and Cognitive Discover Foundation, Toronto, and was not involved with the study, said it is believed “that the excitatory-inhibitory balance may be relevant to brain health and disease.”

Dr. McIntyre also pointed out that the study “highlights not only the repurposing of a well-known medicine but also exploit[s] the potential brain therapeutic effects of immune targets that indirectly affect inhibitory systems, resulting in potentially a safer treatment for anxiety – the most common affliction of humanity.”

Approximately one-third of critical care workers reported some degree of depression, anxiety, or somatic symptoms in the early phase of the COVID-19 pandemic, based on survey results from 939 health care professionals.

The emotional response of professionals in a critical care setting in the early phase of the COVID-19 pandemic has not been well studied, Robyn Branca, PhD, and Paul Branca, MD, of Carson Newman University and the University of Tennessee Medical Center, both in Knoxville, wrote in an abstract presented at the virtual Critical Care Congress sponsored by the Society of Critical Care Medicine.

The prevalence of depression, anxiety, and somatization is low in the general population overall, but the researchers predicted that these conditions increased among workers in critical care settings early in the pandemic.

To assess the prevalence of psychological problems during that time, they sent an email survey on April 7, 2020, to members of the Society of Critical Care Medicine. The survey collected data on demographics, perceived caseload, and potential course of the pandemic. The survey also collected responses to assessments for depression (using the Patient Health Questionnaire–9), anxiety (using the Generalized Anxiety Disorder [GAD] Scale–7), and symptom somatization (using the PHQ-15).

Of the 939 survey respondents, 37% were male, 61.4% were female, and 1.4% gave another or no response.

Overall, 32.3% reported encountering 0-50 COVID-19 cases, 31.1% had encountered 51-200 cases, 12.5% had encountered 201-500 cases, 9.4% had encountered 501-1000 cases, and 13.7% had encountered more than 1,000 cases.

Based on the PHQ-9 depression scale, 44.9% of the respondents had minimal symptoms, 31.1% mild symptoms, 14.3% moderate symptoms, and 9.7% met criteria for severe depressive symptoms. Based on the GAD-7 anxiety scale, 35.5% had minimal symptoms, 32.9% mild, 16.8% moderate, and 14.8% had severe symptoms. Based on the PHQ-15 somatization scale, 39.6% of respondents showed minimal symptoms, whereas 38.2% showed mild symptoms, 17.3% moderate symptoms, and 4.9% had a severe degree of somatic symptoms.

The study findings were limited by the reliance on self-reports; however, the results indicate that a high percentage of critical care workers experienced significant, diagnosable levels of depression, anxiety, and somatic symptoms, the researchers said.

The standard guidance is to pursue individual intervention for anyone with scores of moderate or severe on the scales used in the survey, the researchers said.

Therefore, the findings represent “an alarming degree of mental health impact,” they emphasized. “Immediate mitigation efforts are needed to preserve the health of our ICU workforce.”

The study is important at this time because clinician fatigue and occupational stress are at endemic levels, Bernard Chang, MD, of Columbia University Irving Medical Center, New York City, said in an interview. “It is vital that we take stock of how frontline workers in critical care settings are doing overall,” said Dr. Chang.  

Dr. Chang, who was not involved with the study but has conducted research on mental health in frontline health care workers during the pandemic, said he was not surprised by the findings. “This work builds on the growing body of literature in the pandemic noting high levels of stress, fatigue, and depression/anxiety symptoms across many frontline workers, from emergency department staff, first responders and others. These are all data points highlighting the urgent need for a broad safety net, not only for patients but the providers serving them.”

The takeaway message: “Clinicians are often so focused on providing care for their patients that they may overlook the need to care for their own well-being and mental health,” said Dr. Chang.

As for additional research, “we need to now take this important data and build on creating and identifying tangible solutions to improve the morale of the acute care/health care workforce to ensure career longevity, professional satisfaction, and overall well-being,” Dr. Chang emphasized. Mental health and morale affect not only health care workers, but also the patients they care for. Well–cared for health care providers can be at their best to provide the optimal care for their patients.

The study received no outside funding. The researchers and Dr. Chang disclosed no relevant financial relationships.

Psychiatric disorders are tied to an increased risk of COVID-19 breakthrough infection, particularly among older adults, new research shows.

“Psychiatric disorders remained significantly associated with incident breakthrough infections above and beyond sociodemographic and medical factors, suggesting that mental health is important to consider in conjunction with other risk factors,” wrote the investigators, led by Aoife O’Donovan, PhD, University of California, San Francisco.

Individuals with psychiatric disorders “should be prioritized for booster vaccinations and other critical preventive efforts, including increased SARS-CoV-2 screening, public health campaigns, or COVID-19 discussions during clinical care,” they added.

The study was published online in JAMA Network Open.
 

Elderly most vulnerable

The researchers reviewed the records of 263,697 veterans who were fully vaccinated against COVID-19.

Just over a half (51.4%) had one or more psychiatric diagnoses within the last 5 years and 14.8% developed breakthrough COVID-19 infections, confirmed by a positive SARS-CoV-2 test.

Psychiatric diagnoses among the veterans included depression, posttraumatic stress, anxiety, adjustment disorder, substance use disorder, bipolar disorder, psychosis, ADHD, dissociation, and eating disorders.

In the overall sample, a history of any psychiatric disorder was associated with a 7% higher incidence of breakthrough COVID-19 infection in models adjusted for potential confounders (adjusted relative risk, 1.07; 95% confidence interval, 1.05-1.09) and a 3% higher incidence in models additionally adjusted for underlying medical comorbidities and smoking (aRR, 1.03; 95% CI, 1.01-1.05).

Most psychiatric disorders were associated with a higher incidence of breakthrough infection, with the highest relative risk observed for substance use disorders (aRR, 1.16; 95% CI, 1.12 -1.21) and adjustment disorder (aRR, 1.13; 95% CI, 1.10-1.16) in fully adjusted models.

Older vaccinated veterans with psychiatric illnesses appear to be most vulnerable to COVID-19 reinfection.

In veterans aged 65 and older, all psychiatric disorders were associated with an increased incidence of breakthrough infection, with increases in the incidence rate ranging from 3% to 24% in fully adjusted models.

In the younger veterans, in contrast, only anxiety, adjustment, and substance use disorders were associated with an increased incidence of breakthrough infection in fully adjusted models.

Psychotic disorders were associated with a 10% lower incidence of breakthrough infection among younger veterans, perhaps because of greater social isolation, the researchers said.
 

Risky behavior or impaired immunity?

“Although some of the larger observed effect sizes are compelling at an individual level, even the relatively modest effect sizes may have a large effect at the population level when considering the high prevalence of psychiatric disorders and the global reach and scale of the pandemic,” Dr. O’Donovan and colleagues wrote.

They noted that psychiatric disorders, including depression, schizophrenia, and bipolar disorders, have been associated with impaired cellular immunity and blunted response to vaccines. Therefore, it’s possible that those with psychiatric disorders have poorer responses to COVID-19 vaccination.

It’s also possible that immunity following vaccination wanes more quickly or more strongly in people with psychiatric disorders and they could have less protection against new variants, they added.

Patients with psychiatric disorders could be more apt to engage in risky behaviors for contracting COVID-19, which could also increase the risk for breakthrough infection, they said.

The study was supported by a UCSF Department of Psychiatry Rapid Award and UCSF Faculty Resource Fund Award. Dr. O’Donovan reported no relevant disclosures.
