The novel antipsychotic agent SEP-363856 (Sunovion Pharmaceuticals) has a significant and ongoing effect on negative symptoms in patients with schizophrenia, new research shows.

Results of a phase 2, placebo-controlled trial show SEP-363856 significantly decreased total scores on the Brief Negative Symptom Scale (BNSS), and lowered subscale scores for such symptoms as alogia and asociality, compared with placebo.

The active-treatment group also showed significantly lower scores on the negative subscale of the Positive and Negative Syndrome Scale (PANSS). During an open-label extension of the study, both BNSS total scores and PANSS negative symptom scores continued to decrease.

Overall, the results “provide further confirmation of the effectiveness of SEP-363856 in treating schizophrenia,” study investigator Kenneth Koblan, PhD, of Sunovion said in an interview.

He added that the compound also showed “a favorable safety and tolerability profile that is differentiated from first and second generation antipsychotics, and which is consistent with the absence of D2-receptor binding.”

The findings were presented at the 2021 annual congress of the Schizophrenia International Research Society.
 

FDA breakthrough designation

SEP-363856 has a completely different mechanism of action from currently available antipsychotics.

In May 2019, it was granted breakthrough therapy designation by the Food and Drug Administration as a novel treatment for patients with schizophrenia.

Phase 2 data published in the New England Journal of Medicine in 2020 showed it achieved significant and clinically meaningful improvements in PANSS total scores after 4 weeks in patients hospitalized with an acute exacerbation of schizophrenia. It also showed durable effects out to 26 weeks.

In the current analysis, the investigators focused on negative symptoms, both in the initial acute treatment phase and an open-label extension.

They analyzed data from the previous phase 2 trial using a validated Uncorrelated PANSS Score Matrix (UPSM) transformation of the PANSS to isolate the effects of the drug on apathy/avolition and deficit of expression. They also used the BNSS.

Patients aged 18-40 years with an acute exacerbation of schizophrenia were randomly assigned to receive either 50 mg or 75 mg of SEP-363856 per day (n = 120) or matching placebo (n = 125) for 4 weeks. Completers were eligible for enrollment in a 26-week phase 2 extension study of 25 mg, 50 mg, or 75 mg of SEP-363856 per day.

The mean age of the participants was 30 years, and 64% were men. The treatment groups were balanced in terms of demographics.

Significant improvement

The BNSS total score decreased significantly with SEP-363856 over placebo during the 4-week acute treatment period, at a mean reduction of 7.1 versus 2.7, or an effect size of 0.48 (P < .001).

Scores on the PANSS negative subscale also decreased significantly with the active drugs, with an effect size of 0.37 versus placebo (P < .05), as did scores on the UPSM apathy/avolition and deficit of expression subscales (effect size, 0.32; P < .05 for both).

In addition, there were significant reductions with SEP-363856 over placebo for the BNSS alogia, asociality, anhedonia, avolition, and blunted-affect subscales (P < .05 for all comparisons) but not for the distress subscale.

During the open-label extension, mean BNSS total scores continued to decrease for the SEP-363856 group, at an average reduction versus extension enrollment across the whole cohort of 11.3.

PANSS negative symptom scores also decreased by an average of 5.2 points, while UPSM apathy/volition scores decreased by 0.4 points on average. UPSM deficit expression scores decreased by 0.5 points.

When the researchers restricted the analysis to those who received SEP-363856 during the acute treatment phase and then continued using the drug during the open-label extension, they found BNSS total scores decreased by an additional 8 points.

Similarly, PANSS negative symptom scores decreased during the open-label extension by an average of 4 points. For UPSM apathy/avolition and deficit of expression, the additional decrease was 0.3 points on average.

In addition, an analysis of the drug’s safety and tolerability showed that, compared with the commonly prescribed antipsychotic lurasidone, it had a significantly lower risk of adverse effects. In addition, the drug was not associated with extrapyramidal symptoms and had no adverse cardiometabolic effects, Dr. Koblan reported.
 

Still in development

Commenting on the findings, René S. Kahn, MD, PhD, chair of the department of psychiatry, Icahn School of Medicine at Mount Sinai, New York, noted that, although the results showed that the drug had a “nice effect” on negative symptoms, it’s still in development.

Dr. Kahn, who was not involved in the research, said “we’ve all seen” drugs that were extremely promising in phase 2 trials that have then failed in phase 3 trials. “The proof of the pudding is phase 3, and we have to wait and see,” he added.

“Obviously I hope it’s going to work out, because we are in desperate need of new drugs, especially with a new mechanism of action and not ‘me too’ drugs. And this definitely not a ‘me too’ drug,” Dr. Kahn said. However, “we’ll have to wait.”

He noted that psychosis is often the primary focus of schizophrenia management. However, he added, cognitive and negative symptoms are also “very relevant” to the disorder.

“In fact, both of them may be more important in determining the long-term outcome of schizophrenia than psychosis, [and] most of the antipsychotics that we currently have are not very effective against negative symptoms,” he said.

“So it would really be a breakthrough if we have a drug that is really effective not only against positive psychotic symptoms, but also against negative and possibly cognitive, symptoms,” Dr. Kahn added.

Commenting on the drug’s safety, Dr. Kahn said there is a need for head-to-head studies of active drugs before any firm conclusions can be drawn.

However, he noted the exploratory analysis suggests it has a different side effect profile, compared with other medications on the market.

The study was supported by Sunovion Pharmaceuticals. Dr. Koblan and his coinvestigators are employees of Sunovion.

Key clinical point: Lipomatous pseudohypertrophy (LPH) of the pancreas is a rare disease with varied clinical presentation and different signs and symptoms. It could be a cause of exocrine pancreatic insufficiency (EPI) and thus requires patient follow-up and appropriate treatment.

Major finding: LPH of pancreas was diagnosed in a 26-year-old man under evaluation. Computed tomography scan and magnetic resonance imaging showed a diffusely enlarged pancreas with scattered remnants of pancreatic parenchyma. Pancreatic exocrine and endocrine functions were maintained as pockets of pancreatic parenchyma were preserved. The patient was discharged with an advice for regular follow-ups.

Study details: Findings are from analysis of a 26-year-old man admitted to hospital with loss of appetite for 6 months.

Key clinical point: Overt exocrine insufficiency is rare in patients with pancreatic trauma but some asymptomatic patients may show biochemical exocrine insufficiencies on specific investigations, particularly after pancreatic resection.

Major finding: Severe pancreatic exocrine insufficiency (PEI) was seen in 4 patients (20%), of which 3 had undergone pancreatic resection (P = .7). Only 1 patient complained of steatorrhea. Patients undergoing pancreatic resection had lower fecal elastase than those who did not (median, 113 μg/g vs. 162.5 μg/g), although difference was not significant statistically (P = .7).

Study details: Findings are from analysis of 20 patients with grade 2-5 pancreatic injury (age, 18-65 years) who were admitted and managed at the division of Trauma Surgery and Critical Care. Patients either underwent partial pancreatic resection (n=12) or nonoperative management or operation without resection (n=8).

Disclosures: The study did not receive any funding. The authors declared no conflicts of interest.

Patients undergoing pancreatic resection had lower fecal elastase than those who did not (median, 113 μg/g vs. 162.5 μg/g), although difference was not significant statistically (P = .7).

Study details: Findings are from analysis of 20 patients with grade 2-5 pancreatic injury (age, 18-65 years) who were admitted and managed at the division of Trauma Surgery and Critical Care. Patients either underwent partial pancreatic resection (n=12) or nonoperative management or operation without resection (n=8).

Disclosures: The study did not receive any funding. The authors declared no conflicts of interest.

Key clinical point: During long-term follow-up, exocrine pancreatic insufficiency (EPI) was observed in more than half of the patients who underwent curative gastrectomy and had completed oncological treatment for gastric adenocarcinoma. Postoperative radiotherapy as an adjunct to adjuvant chemotherapy was a serious risk factor for EPI development.

Major finding: Fecal elastase-1 (FE-1) less than 200 μg/g, considered a measure of EPI, was present in 63.8% of patients. A higher proportion of patients with low FE-1 (less than 100 μg/g) received adjuvant chemoradiotherapy vs. those with moderate FE-1 (100-200 μg/g; P = .012) and normal FE-1 (less than 200 μg/g; P less than .001).

Study details: This study included 69 patients with gastric cancer who underwent total or subtotal curative gastrectomy with D2 lymphadenectomy and had long-term disease-free survival success. Patients were followed up for 16-120 months.

In a global meta-analysis of more than 7,000 patients who were hospitalized with COVID-19, individuals with overweight or obesity were more likely to need respiratory support but were not more likely to die in the hospital, compared to individuals of normal weight.
 

Compared to patients without diabetes, those with diabetes had higher odds of needing invasive respiratory support (with intubation) but not for needing noninvasive respiratory support or of dying in the hospital.

“Surprisingly,” among patients with diabetes, being overweight or having obesity did not further increase the odds of any of these outcomes, the researchers wrote. The finding needs to be confirmed in larger studies, they said, because the sample sizes in these subanalyses were small and the confidence intervals were large.

The study by Danielle K. Longmore, PhD, of Murdoch Children’s Research Institute (MCRI), Melbourne, and colleagues from the International BMI-COVID consortium, was published online April 15 in Diabetes Care.

This new research “adds to the known data on the associations between obesity and severe COVID-19 disease and extends these findings” to patients who are overweight and/or have diabetes, Dr. Longmore, a pediatric endocrinologist with a clinical and research interest in childhood and youth obesity, said in an interview.

Immunologist Siroon Bekkering, PhD, of Radboud University Medical Center, Nijmegen, the Netherlands, explained that never before have so much data of different types regarding obesity been combined in one large study. Dr. Bekkering is a coauthor of the article and was a principal investigator.

“Several national and international observations already showed the important role of overweight and obesity in a more severe COVID-19 course. This study adds to those observations by combining data from several countries with the possibility to look at the risk factors separately,” she said in a statement from her institution.

“Regardless of other risk factors (such as heart disease or diabetes), we now see that too high a BMI [body mass index] can actually lead to a more severe course in [coronavirus] infection,” she said.
 

Study implications: Data show that overweight, obesity add to risk

These latest findings highlight the urgent need to develop public health policies to address socioeconomic and psychological drivers of obesity, Dr. Longmore said.

“Although taking steps to address obesity in the short term is unlikely to have an immediate impact in the COVID-19 pandemic, it will likely reduce the disease burden in future viral pandemics and reduce risks of complications like heart disease and stroke,” she observed in a statement issued by MCRI.

Coauthor Kirsty R. Short, PhD, a research fellow at the University of Queensland, Brisbane, Australia, noted that “obesity is associated with numerous poor health outcomes, including increased risk of cardiometabolic and respiratory disease and more severe viral disease including influenza, dengue, and SARS-CoV-1.

“Given the large scale of this study,” she said, “we have conclusively shown that being overweight or obese are independent risk factors for worse outcomes in adults hospitalized with COVID-19.”

“At the moment, the World Health Organization has not had enough high-quality data to include being overweight or obese as a risk factor for severe COVID-19 disease,” added another author, David P. Burgner, PhD, a pediatric infectious diseases clinician scientist from MCRI.

Does being overweight up risk of worse COVID-19 outcomes?

About 13% of the world’s population are overweight, and 40% have obesity. There are wide between-country variations in these data, and about 90% of patients with type 2 diabetes are overweight or obese, the researchers noted.

The Organisation for Economic Co-operation and Development reported that the prevalence of obesity in 2016-2017 was 5.7% to 8.9% in Asia, 9.8% to 16.8% in Europe, 26.5% in South Africa, and 40.0% in the United States, they added.

Obesity is common and has emerged as an important risk factor for severe COVID-19. However, most previous studies of COVID-19 and elevated BMI were conducted in single centers and did not focus on patients with overweight.

To investigate, the researchers identified 7,244 patients (two-thirds were overweight or obese) who were hospitalized with COVID-19 in 69 hospitals (18 sites) in 11 countries from Jan. 17, 2020, to June 2, 2020.

Most patients were hospitalized with COVID-19 in the Netherlands (2,260), followed by New York City (1,682), Switzerland (920), St. Louis (805), Norway, Italy, China, South Africa, Indonesia, Denmark, Los Angeles, Austria, and Singapore.

Just over half (60%) of the individuals were male, and 52% were older than 65.

Overall, 34.8% were overweight, and 30.8% had obesity, but the average weight varied considerably between countries and sites.
 

Increased need for respiratory support, same mortality risk

Compared with patients with normal weight, patients who were overweight had a 44% increased risk of needing supplemental oxygen/noninvasive ventilation, and those with obesity had a 75% increased risk of this, after adjustment for age (< 65, ≥ 65), sex, hypertension, diabetes, or preexisting cardiovascular disease or respiratory conditions.

Patients who were overweight had a 22% increased risk of needing invasive (mechanical) ventilation, and those with obesity had a 73% increased risk of this, after multivariable adjustment.

Being overweight or having obesity was not associated with a significantly increased risk of dying in the hospital, however.

“In other viral respiratory infections, such as influenza, there is a similar pattern of increased requirement for ventilatory support but lower in-hospital mortality among individuals with obesity, when compared to those with normal range BMI,” Dr. Longmore noted. She said that larger studies are needed to further explore this finding regarding COVID-19.

Compared to patients without diabetes, those with diabetes had a 21% increased risk of requiring invasive ventilation, but they did not have an increased risk of needing noninvasive ventilation or of dying in the hospital.

As in previous studies, individuals who had cardiovascular and preexisting respiratory diseases were not at greater risk of needing oxygen or mechanical ventilation but were at increased risk for in-hospital death. Men had a greater risk of needing invasive mechanical ventilation, and individuals who were older than 65 had an increased risk of requiring oxygen or of dying in the hospital.
 

A living meta-analysis, call for more collaborators

“We consider this a ‘living meta-analysis’ and invite other centers to join us,” Dr. Longmore said. “We hope to update the analyses as more data are contributed.”

No specific project funded the study. The authors have disclosed no relevant financial relationships.

Accelerated brain aging among HIV-infected adults might be caused in part by altered deep sleep patterns, new research suggests.

Using a measure known as the brain age index (BAI) – a machine-learning model that measures deviations in brain activity during sleep relative to healthy individuals – investigators identified 34 sleep electroencephalogram features that were significantly altered by HIV infection. The most notable of these was the decline in slow-wave activity during non-REM sleep, which has been previously associated with MRI markers of brain aging in healthy adults.

“One of the functions of slow-wave sleep appears to be its association with the glymphatic system, which clears [metabolic] waste products and supports memory consolidation,” study coauthor Brandon Westover, MD, PhD, associate professor of neurology at Massachusetts General Hospital/Harvard Medical School, Boston, said in an interview. “It’s also believed to be associated with an accelerated risk for dementia and other cognitive issues.”

Previous work conducted at Johns Hopkins and other institutions confirm Dr. Westerson’s hypothesis. Charlene Gamaldo, MD, medical director of Johns Hopkins Sleep Disorders Center in Baltimore, pointed to other study findings in patients with neurodegenerative disease that have shown a link between predominant habitual sleep positions and dementia, potentially driven by inefficient glymphatic transport. Dr. Gamaldo was not involved in the current study.
 

Threefold acceleration vs. healthy volunteers

“We’ve been grappling with whether people with HIV on ART experience accelerated aging or accentuated aging,” coauthor Shibani Mukerji, MD, PhD, associate director of the neuroinfectious diseases unit at Massachusetts General, said in an interview. “We have yet to have biomarkers to address this question, and most of the tools are limited to invasive or expensive diagnostics. “In general, sleep and its influence on health have been understudied in the HIV population.”

To address this question, the researchers retrospectively examined a Massachusetts General Hospital database of diagnostic sleep study participants from 2008 to 2018, identifying 3,155 healthy, HIV-negative control subjects and 43 HIV-positive participants. Thirty-four (79%) of the HIV-positive participants were men, 30 (70%) were White, and 38 (93%) were virally suppressed at the time of their sleep study. Four patients were taking efavirenz, 13 were taking an integrase strand transfer inhibitor, and all were adherent to antiretroviral therapy (ART) at the time of their sleep study.

None of the HIV-positive participants had a history of secondary brain infection or brain tumor, although one patient had recovered fully from a previous HIV-associated encephalitis.

The study findings, which were published online March 30, 2021, in Sleep, first showed that HIV-positive participants had an average BAI of 3.19 years (standard error of the mean,1.43 years), compared with the control participants, who had an average BAI of –0.16 (SEM, 0.18 years).

These findings held after adjustment for potential confounders (age, sex, race, tobacco use disorder, and alcohol use disorder), yielding a total effect of HIV on BAI of 3.35 years (P < .01).

“Despite being well controlled on ART, HIV-positive individuals who had participated in the sleep studies still had elevated brain age,” said Dr. Westover. “We didn’t have enough information to determine the pathways by which HIV increases the BAI, but chronic inflammation appears to be an important factor.”

The findings also demonstrated that comorbidities accounted for roughly a quarter of the effect of HIV on BAI. However, the lack of statistical significance (in part because of the limited sample size) precluded the ability to determine if treating or preventing them might influence the degree to which HIV affects BAI and, in turn, cognitive decline.
 

HIV, sleep EEG, and brain aging

To estimate the effect of HIV on specific EEG features, the investigators again evaluated the total effect, this time replacing BAI with individual sleep EEG as the primary outcome. Among the 34 EEG features significantly altered by HIV, none were observed in the wake state and three were altered in REM (each associated with reduced delta band power). The rest were distributed in non-REM sleep, most notably in the deepest phase, corresponding to relative reductions in delta wave power.

The study findings build on the investigators’ previous research, which demonstrated an association between greater mean BAI and dementia, psychotic disorders, and anxiety/mood disorders in HIV-negative subjects, all of which correlated to attenuated slow-wave sleep.

More research is needed to determine if BAI, as it relates to sleep EEG, can effectively track the risk for cognitive decline among HIV-positive people, and if certain confounders might attenuate or accelerate this risk.

“While our team has not specifically looked at BAI, the findings in this study seem perfectly in line with what we have found with our own research,” Dr. Gamaldo said in an interview. “Not only have we observed a robust association between minimal cognitive deficits and patients’ sleep complaints (despite being virally controlled), but also, the potential value of measuring the architectural sleep features by ambulatory EEG to identify HIV patients’ vulnerability to cognitive decline.”

“BAI is a physiologic, easily repeatable measurement that can be used to track if an intervention is having a good effect,” Dr. Westover said.

Dr. Mukerji concurred, adding that “having a tool that can be used in resource-challenged settings and also be incorporated into longitudinal studies in a patient population with substantial age-related comorbidities, like HIV, would be really helpful.”

Dr. Westover and Dr. Mukerji disclosed no relevant financial relationships. Dr. Gamaldo is a consultant for Jazz Pharmaceuticals, and has received author royalties from UpToDate and honoraria from Medscape CME for content contribution.

The study findings, which were published online March 30, 2021, in Sleep, first showed that HIV-positive participants had an average BAI of 3.19 years (standard error of the mean,1.43 years), compared with the control participants, who had an average BAI of –0.16 (SEM, 0.18 years).

These findings held after adjustment for potential confounders (age, sex, race, tobacco use disorder, and alcohol use disorder), yielding a total effect of HIV on BAI of 3.35 years (P < .01).

“Despite being well controlled on ART, HIV-positive individuals who had participated in the sleep studies still had elevated brain age,” said Dr. Westover. “We didn’t have enough information to determine the pathways by which HIV increases the BAI, but chronic inflammation appears to be an important factor.”

The findings also demonstrated that comorbidities accounted for roughly a quarter of the effect of HIV on BAI. However, the lack of statistical significance (in part because of the limited sample size) precluded the ability to determine if treating or preventing them might influence the degree to which HIV affects BAI and, in turn, cognitive decline.
 

HIV, sleep EEG, and brain aging

To estimate the effect of HIV on specific EEG features, the investigators again evaluated the total effect, this time replacing BAI with individual sleep EEG as the primary outcome. Among the 34 EEG features significantly altered by HIV, none were observed in the wake state and three were altered in REM (each associated with reduced delta band power). The rest were distributed in non-REM sleep, most notably in the deepest phase, corresponding to relative reductions in delta wave power.

The study findings build on the investigators’ previous research, which demonstrated an association between greater mean BAI and dementia, psychotic disorders, and anxiety/mood disorders in HIV-negative subjects, all of which correlated to attenuated slow-wave sleep.

More research is needed to determine if BAI, as it relates to sleep EEG, can effectively track the risk for cognitive decline among HIV-positive people, and if certain confounders might attenuate or accelerate this risk.

“While our team has not specifically looked at BAI, the findings in this study seem perfectly in line with what we have found with our own research,” Dr. Gamaldo said in an interview. “Not only have we observed a robust association between minimal cognitive deficits and patients’ sleep complaints (despite being virally controlled), but also, the potential value of measuring the architectural sleep features by ambulatory EEG to identify HIV patients’ vulnerability to cognitive decline.”

“BAI is a physiologic, easily repeatable measurement that can be used to track if an intervention is having a good effect,” Dr. Westover said.

Dr. Mukerji concurred, adding that “having a tool that can be used in resource-challenged settings and also be incorporated into longitudinal studies in a patient population with substantial age-related comorbidities, like HIV, would be really helpful.”

Accelerated brain aging among HIV-infected adults might be caused in part by altered deep sleep patterns, new research suggests.

Using a measure known as the brain age index (BAI) – a machine-learning model that measures deviations in brain activity during sleep relative to healthy individuals – investigators identified 34 sleep electroencephalogram features that were significantly altered by HIV infection. The most notable of these was the decline in slow-wave activity during non-REM sleep, which has been previously associated with MRI markers of brain aging in healthy adults.

“One of the functions of slow-wave sleep appears to be its association with the glymphatic system, which clears [metabolic] waste products and supports memory consolidation,” study coauthor Brandon Westover, MD, PhD, associate professor of neurology at Massachusetts General Hospital/Harvard Medical School, Boston, said in an interview. “It’s also believed to be associated with an accelerated risk for dementia and other cognitive issues.”

Previous work conducted at Johns Hopkins and other institutions confirm Dr. Westerson’s hypothesis. Charlene Gamaldo, MD, medical director of Johns Hopkins Sleep Disorders Center in Baltimore, pointed to other study findings in patients with neurodegenerative disease that have shown a link between predominant habitual sleep positions and dementia, potentially driven by inefficient glymphatic transport. Dr. Gamaldo was not involved in the current study.
 

Threefold acceleration vs. healthy volunteers

“We’ve been grappling with whether people with HIV on ART experience accelerated aging or accentuated aging,” coauthor Shibani Mukerji, MD, PhD, associate director of the neuroinfectious diseases unit at Massachusetts General, said in an interview. “We have yet to have biomarkers to address this question, and most of the tools are limited to invasive or expensive diagnostics. “In general, sleep and its influence on health have been understudied in the HIV population.”

To address this question, the researchers retrospectively examined a Massachusetts General Hospital database of diagnostic sleep study participants from 2008 to 2018, identifying 3,155 healthy, HIV-negative control subjects and 43 HIV-positive participants. Thirty-four (79%) of the HIV-positive participants were men, 30 (70%) were White, and 38 (93%) were virally suppressed at the time of their sleep study. Four patients were taking efavirenz, 13 were taking an integrase strand transfer inhibitor, and all were adherent to antiretroviral therapy (ART) at the time of their sleep study.

None of the HIV-positive participants had a history of secondary brain infection or brain tumor, although one patient had recovered fully from a previous HIV-associated encephalitis.

Every psychiatrist knows that this past year has been a challenge. The COVID-19 pandemic altered our lives, practically overnight, in ways that most of us had never anticipated.

There were months of lockdown. A new work-from-home transition. Recommendations to distance and mask. The destruction and recreation of our social lives. And the end of some industries as we have known them.

Over a year later, many children are still in virtual school. This lifestyle and economic toll do not even begin to include the horror experienced by exhausted and distressed health care workers or by the many who have lost a loved one or survived a hospitalization. National and international anxiety are running high. More people are seeking mental health care, and many of the patients we were caring for prior to the pandemic have been distressed.

Rates of both depression and anxiety are up, and the fear has been that the isolation of lockdowns, with their emotional and economic toll, would also increase suicide rates. Despite the increase in psychiatric symptoms and general distress, initial studies in the United States have shown that overall suicide rates in the early months of the pandemic were lower than in prior years.

A study published in The Lancet looked at suicide data from around the world and compared expected suicides, based on data from past years, with observed suicides. The researchers restricted their analysis to the countries, and regions of countries, where real-time suicide data were available through internet searches. Their paper is based on findings from 21 countries, including 16 high-income countries and five upper-middle–income countries (from regions where data were available). The overall analysis showed a drop in suicides by 5% when looking at the first 4 months of the pandemic, defined as April 1, 2020, to July 31, 2020. There were statistically significant increases in suicide only in Vienna, Puerto Rico, and Japan.

Igor Galynker, MD, PhD, directs the Suicide Research and Prevention Lab and the Zirinsky Center for Bipolar Disorder at the Icahn School of Medicine at Mount Sinai. He was not surprised by these findings.

“This is an important study,” Dr. Galynker said. “When it was discovered that U.S. rates went down, it was ‘U.S. specific’ and it was confounded by the fact that there was a dramatic increase in opiate overdose deaths in the U.S., which are not reported as suicides. This study shows that the decrease is international and that the finding in the United States is not related to the spike in overdose deaths.”

The study authors postulated that the drop in suicide may be due to proactive protective measures that societies have put in place, such as improved mental health services and fiscal support to mitigate financial consequences of the pandemic. They explained that “communities might have actively tried to support at-risk individuals, people might have connected in new ways, and some relationships might have been strengthened by households spending more time with each other. For some people, everyday stresses might have been reduced during stay-at-home periods, and for others the collective feeling of ‘we’re all in this together’ might have been beneficial”.

Dr. Galynker noted that, in times of calamity, suicide rates historically go down. “Short-term disasters invoke a fight-or-flight response that mobilizes us and improves our functioning under stress. Those acute responses last 2-3 months and then chronic stress sets in.” He is concerned that there will be increases in suicide rates down the road.

It is possible that individuals who consider social gatherings to be stressful, or who are bullied at school, may have found some relief from social interactions and expectations during the lockdown. “Some people have discovered that they like their families!” Dr. Galynker said.

While suicide rates have gone down, that is not true for all population subsets, and the authors of the Lancet paper noted that they were unable to give breakdowns of rates for different demographics.

Paul Nestadt, MD, is codirector of the Johns Hopkins Anxiety Disorders Clinic and studies suicide, firearms, and opiates. He looked at suicides in Maryland during the first 2 months of the lockdown (March 5, 2020 to May 7, 2020) and found that, while rates were down among White Maryland residents, compared with prior years, they were increased among Black Maryland residents. Studies in Connecticut and Chicago yielded similar findings. These findings indicate that the overall trends may not reflect the impact on a specific subpopulation.

Dr. Nestadt talked about the disparities of suicide trends. “Communities hit harder by this pandemic in terms of sickness and death may experience more distress in ways that may come out as suicide in the context of other comorbid mood disorders. Also, in line with the idea of suicide as a marker of community- or population-level distress, there’s a general idea that having less of an economic cushion makes the pandemic more of a problem for some than for others. We know that suicide has been correlated to economic distress in general, and it makes sense that it would be community-specific where there is more economic duress.”

It has been a difficult year – not just for the United States, but for the entire world. One thing that may come of it is a unique opportunity to look at how stress and loss affect suicide rates, with the hope that preventive measures will follow.
