Novel antidepressant shows promise as add-on therapy
as add-on therapy
Adjunctive treatment with the novel oral medication REL-1017 (esmethadone) is effective in adults with major depressive disorder (MDD) who have failed other antidepressants, new research suggests.
REL-1017, from Relmada Therapeutics, is a novel N-methyl-D-aspartate receptor (NMDAR) channel blocker that preferentially targets hyperactive channels while maintaining physiologic glutamatergic neurotransmission.
Results from a phase 2a study showed rapid “therapeutic efficacy,” with a statistical difference by day 4, and the improvement was “robust,” with an effect size of 0.7 to 1. The positive outcome was also sustained for at least 1 week after treatment discontinuation, coinvestigator Paolo L. Manfredi, MD, chief scientific officer, Relmada Therapeutics, noted.
“Considering that the available traditional antidepressants have an average effect size around 0.3, this novel, potential rapid-acting antidepressant … holds great promise for millions of patients suffering from depression,” Dr. Manfredi told this news organization.
These results were obtained with a “very-well-tolerated once-daily oral NMDAR antagonist, without the dissociative effects seen with ketamine,” he added.
The findings were published online in the American Journal of Psychiatry.
‘Clear need’ for better therapies
It is estimated that more than half of patients with MDD fail to respond adequately following their first standard antidepressant treatment. In addition, responses are often delayed by 4-8 weeks after starting an antidepressant.
Therefore, there is a “clear need” to develop drugs for MDD that act quickly and with improved efficacy, the investigators note.
The phase 2a study of REL-1017 enrolled 62 adult patients (45% women) aged 18-65 years with moderate to severe MDD and no significant psychiatric comorbidity. All had failed to benefit from one to three standard antidepressant treatments in their current major depressive episode.
The researchers evaluated two doses of REL-1017 (25 mg and 50 mg once daily) vs. placebo given as adjunctive treatment. The assigned treatment lasted 7 days.
The primary study objectives were safety and tolerability. Results showed no serious adverse events (AEs), and no patients experienced treatment-emergent AEs that led to the stopping of treatment.
In addition, patients receiving the active drug experienced mild or moderate transient AEs comparable to placebo, with no opioid, dissociative, or psychotomimetic symptoms, or withdrawal effects when treatment ended.
The most common AEs reported were headache, constipation, nausea, and sleepiness.
Significant efficacy
The primary efficacy endpoint was the Montgomery–Åsberg Depression Scale (MADRS) score.
MADRS scores showed improvement on day 4 of treatment in both REL-1017 groups, and the improvement continued through day 7 (last dose) and day 14 (7 days after the last dose), with P ≤ .0308 and effect sizes ranging from 0.7 to 1.0.
Mean change from baseline in MADRS scores showed more improvement at the end of the dosing period for both dosing groups (–16.8 with 25 mg and –16.6 with 50 mg) vs. –8.8 with placebo.
Results of the other efficacy endpoints of Symptoms of Depression Questionnaire (SDQ) score and Clinical Global Impressions severity scale (CGI-S) and improvement scale (CGI-I) scores were similar to that of the MADRS.
Remission rates (defined as a MADRS score ≤10) on day 14, the last day of efficacy assessment, were 5% with placebo vs. 31% (P = .035) with REL-1017 25 mg and 39% (P = .01) with REL-1017 50 mg.
The number needed to treat to achieve remission on day 14 was four with the 25-mg dose and three with the 50-mg dose.
Phase 3 trials to confirm the efficacy and safety of REL-1017 are in progress, with topline results expected later this year, the investigators report.
The study was funded by Relmada Therapeutics. Dr. Manfredi has received personal fees from and/or held stock ownership in Relmada. Disclosures for the other investigators are fully listed in the original article.

AAN updates treatment guidance on painful diabetic neuropathy
Painful diabetic neuropathy is very common and can greatly affect an individual’s quality of life, guideline author Brian Callaghan, MD, University of Michigan, Ann Arbor, noted in a news release.
“This guideline aims to help neurologists and other doctors provide the highest quality patient care based on the latest evidence,” Dr. Callaghan said.
The recommendations update the 2011 AAN guideline on the treatment of painful diabetic neuropathy. The new guidance was published online Dec. 27, 2021, in Neurology and has been endorsed by the American Association of Neuromuscular & Electrodiagnostic Medicine.
Multiple options
To update the guideline, an expert panel reviewed data from more than 100 randomized controlled trials published from January 2008 to April 2020.
The panel noted that more than 16% of individuals with diabetes experience painful diabetic neuropathy, but it often goes unrecognized and untreated. The guideline recommends clinicians assess patients with diabetes for peripheral neuropathic pain and its effect on their function and quality of life.
Before prescribing treatment, health providers should determine if the patient also has mood or sleep problems as both can influence pain perception.
The guideline recommends offering one of four classes of oral medications found to be effective for neuropathic pain: tricyclic antidepressants such as amitriptyline, nortriptyline, or imipramine; serotonin norepinephrine reuptake inhibitors such as duloxetine, venlafaxine, or desvenlafaxine; gabapentinoids such as gabapentin or pregabalin; and/or sodium channel blockers such as carbamazepine, oxcarbazepine, lamotrigine, or lacosamide.
All four classes of medications have “comparable effect sizes just above or just below our cutoff for a medium effect size” (standardized median difference, 0.5), the panel noted.
In addition, “new studies on sodium channel blockers published since the last guideline have resulted in these drugs now being recommended and considered as effective at providing pain relief as the other drug classes recommended in this guideline,” said Dr. Callaghan.
When an initial medication fails to provide meaningful improvement in pain, or produces significant side effects, a trial of another medication from a different class is recommended.
Pain reduction, not elimination
Opioids are not recommended for painful diabetic neuropathy. Not only do they come with risks, there is also no strong evidence they are effective for painful diabetic neuropathy in the long term, the panel wrote. Tramadol and tapentadol are also not recommended for the treatment of painful diabetic neuropathy.
“Current evidence suggests that the risks of the use of opioids for painful diabetic neuropathy therapy outweigh the benefits, so they should not be prescribed,” Dr. Callaghan said.
For patients interested in trying topical, nontraditional, or nondrug interventions to reduce pain, the guideline recommends a number of options including capsaicin, glyceryl trinitrate spray, and Citrullus colocynthis. Ginkgo biloba, exercise, mindfulness, cognitive-behavioral therapy, and tai chi are also suggested.
“It is important to note that the recommended drugs and topical treatments in this guideline may not eliminate pain, but they have been shown to reduce pain,” Dr. Callaghan said. “The good news is there are many treatment options for painful diabetic neuropathy, so a treatment plan can be tailored specifically to each person living with this condition.”
Along with the updated guideline, the AAN has also published a new Polyneuropathy Quality Measurement Set to assist neurologists and other health care providers in treating patients with painful diabetic neuropathy.
The updated guideline was developed with financial support from the AAN.

Effect of vitamin D supplementation in early psychosis
Low vitamin D is common in patients with first-episode psychosis (FEP), but supplementation does not appear to improve mental or physical symptoms, new data show.
“Previous work, our own and others, has shown that people with psychosis, even soon after their first diagnosis, have low vitamin D levels, but it was not known whether supplementing with vitamin D in people with early psychosis would improve health outcomes,” study investigator Fiona Gaughran, MD, with the Institute of Psychiatry, Psychology & Neuroscience, King’s College London, told this news organization.
“While we did not demonstrate a benefit of supplementation over 6 months, these very high rates of vitamin deficiency and insufficiency may have longer-term negative health impacts which we have not measured, so raising awareness of the need to optimize vitamin D in people with psychosis is important,” said Dr. Gaughran.
The results of the randomized clinical trial were published online Dec. 28 in JAMA Network Open.
Thoughtful approach, negative result
Participants included 149 adults within 3 years of a first presentation with a functional psychotic disorder. The cohort’s mean age was 28 years, 60% were men, 44% were Black or of other racial and ethnic minority groups, and 56% were White.
Seventy-five participants were randomly assigned to receive 120,000 IU of cholecalciferol or matching placebo administered by the researchers in monthly doses with an oral syringe.
“We chose a dose of 120,000 IU monthly (equivalent to 4,000 IU daily) which was expected to safely increase vitamin D levels. The regimen was discussed with experts with lived experience, and took into account that a daily preparation would add to the significant medication load that people with psychosis already carry,” said Dr. Gaughran.
Vitamin D supplementation as administered in this study was safe and led to a significant increase in 25-hydroxyvitamin D concentrations.
However, at 6 months (mean difference, 3.57; 95% confidence interval, –1.11 to 8.25; P = .13).
There was also no apparent benefit of vitamin D supplementation on any secondary outcome, including the PANSS subscores of global function and depression or cardiometabolic risk factors.
“With respect to clinical practice, we cannot now recommend monthly treatments with 120,000 IU of cholecalciferol in FEP,” the investigators note.
The prevalence of vitamin D insufficiency and deficiency was high in the population – 74.6% overall and 93.4% among ethnic minorities.
“Thus, the sample was well suited to detecting any potential benefits that may have arisen from correcting this. However, even in this subgroup, there was no evidence to support the guiding hypothesis” that vitamin D supplementation would improve outcomes in patients with early psychosis, the researchers note.
They suggest that future studies examine the association of vitamin D with brain-related outcomes based on periods of treatment longer than 6 months and administered as daily rather than bolus treatments.
“Future public health strategies should acknowledge the high prevalence of vitamin D insufficiency and deficiency in people with psychosis and consider any reasonable adjustments which may be needed to address this over and above general population guidance,” said Dr. Gaughran.
The study was funded by the Stanley Medical Research Institute and received support from the National Institute for Health Research Maudsley Biomedical Research Centre, King’s College London, and the NIHR Applied Research Collaboration South London. Dr. Gaughran reported receiving speaking honoraria from Otsuka Lundbeck outside the submitted work. A complete list of author disclosures is available with the original article.

Cardiac device interrogation after death ‘richly informative’
Interrogating the cardiac implantable electronic device (CIED) after death can yield important information about critical device malfunction, premortem abnormalities, and the mechanism and timing of death, a new study suggests.
Postmortem CIED interrogation is “richly informative” in assisting both cardiac and forensic investigations and “should be considered for select patients with CIEDs undergoing autopsy,” say Elizabeth Paratz, MBBS, department of cardiology, Baker Heart and Diabetes Institute, Prahran, Australia, and colleagues.
Their study results were published online in JACC: Clinical Electrophysiology.
Cause of death revealed in half of cases
They reviewed CIED interrogations in 260 deceased individuals undergoing medicolegal investigation of sudden death (162 patients) or unexplained death (98 patients) by the Victorian Institute of Forensic Medicine between 2005 and 2020.
Roughly two-thirds were male (68.8%) and their median age was 72.8 years; 202 patients had pacemakers, 56 had defibrillators, and 2 had loop recorders. The cause of death was cardiac in 79.6% of cases.
Postmortem CIED interrogation was successful in 98.5% cases and directly informed cause of death in 131 cases (50.4%), with fatal ventricular arrhythmias identified in 121 patients.
CIED interrogation assisted in determining the cause of death in 63.6% of cases of sudden death and 28.6% of nonsudden death cases.
In 20 cases (7.7%), CIED interrogation uncovered potential device malfunction. Issues included failure to appropriately treat ventricular arrhythmias in 13 cases; lead issues in 3 cases, including 2 cases resulting in failure to treat ventricular arrhythmias; as well as battery depletion in 6 cases.
In 72 patients (27.7%), the device recorded abnormalities in the 30 days before death. These abnormalities included nonsustained ventricular tachycardia in 26 cases, rapid atrial fibrillation in 17, elective replacement indicator or end-of-life status in 22, intrathoracic impedance alarms or lead issues in 3 each, and therapy delivered in 1 instance.
“In several cases, the absence of an arrhythmia carried medicolegal implications: For example, in eight fatal motor vehicle accident cases, only one patient had a ventricular arrhythmia documented on their CIED,” Dr. Paratz and colleagues report.
And in six cases in which the patient was found dead after a prolonged period, CIED interrogation determined time of death. And in one case, CIED interrogation was the primary means of identifying the patient.
Still, postmortem CIED interrogation remains uncommon, the study team notes.
They point to a 2007 survey of Chicago morticians that found roughly 370 CIEDs were explanted per year prior to cremation, but only 4% of morticians had ever returned a CIED to the manufacturer for analysis.
“Encouraging postmortem interrogation of CIEDs may assist in postmarketing surveillance for critical faults, as well as in providing an electrophysiological appraisal of terminal rhythms and device responses in a variety of physiological scenarios,” the researchers say.
The study had no commercial funding. Dr. Paratz is supported by a National Health and Medical Research Council/National Heart Foundation cofunded Postgraduate Scholarship, Royal Australasian College of Physicians JJ Billings Scholarship, and PSA Insurance Cardiovascular Scholarship. The authors have disclosed no relevant financial relationships.

Interrogating the cardiac implantable electronic device (CIED) after death can yield important information about critical device malfunction, premortem abnormalities, and the mechanism and timing of death, a new study suggests.
Postmortem CIED interrogation is “richly informative” in assisting both cardiac and forensic investigations and “should be considered for select patients with CIEDs undergoing autopsy,” say Elizabeth Paratz, MBBS, department of cardiology, Baker Heart and Diabetes Institute, Prahran, Australia, and colleagues.
Their study results were published online in JACC: Clinical Electrophysiology.

New understanding of suicide attempts emerges
even in the absence of a psychiatric disorder.
This finding suggests the genetic underpinnings of suicide attempts are partially shared and partially distinct from those of related psychiatric disorders, the investigators note.
“This study brings us a step closer to understanding the neurobiology of suicidality, with the ultimate goal of developing new treatments and prevention strategies,” Niamh Mullins, PhD, department of psychiatry, department of genetics and genomic sciences, Icahn School of Medicine at Mount Sinai in New York, said in an interview.
The study was published online in Biological Psychiatry.
Largest study to date
In the largest genetic association study of suicide attempt published to date, the researchers conducted a genome-wide association study (GWAS) of 29,782 suicide attempt cases and 519,961 controls in the International Suicide Genetics Consortium (ISGC).
Two loci reached genome-wide significance for suicide attempt – the major histocompatibility complex and an intergenic locus on chromosome 7, the latter of which remained associated with suicide attempt after conditioning on psychiatric disorders and was replicated in an independent cohort of over 14,000 veterans in the Million Veteran Program.
“This is the first replicated genetic locus that contributes more to suicide attempt than related psychiatric disorders,” Dr. Mullins said.
“The study found overlap in the genetic basis of suicide attempt and that of related psychiatric disorders, particularly major depression, but also with that of nonpsychiatric risk factors such as smoking, pain, risk-taking behavior, sleep disturbances, and poorer general health,” Dr. Mullins said.
“These genetic relationships between suicide attempt and nonpsychiatric risk factors were not a by-product of comorbid psychiatric illness, suggesting that there is some shared biological basis between suicide attempt and nonpsychiatric risk factors,” she added.
Dr. Mullins cautioned that the findings do not have any immediate impact on patient care.
“The ultimate goal of this research is to gain insight into the underlying biological pathways involved in suicide attempts or suicidal thoughts, providing potential avenues to treatments and prevention strategies,” she said.
“The study findings also point to the importance of studying the potential direct causal paths between these risk factors and suicide attempt in patients with and without psychiatric illness,” Douglas Ruderfer, PhD, of Vanderbilt University Medical Center, Nashville, Tenn., cofounder and cochair of the consortium and senior author of the paper, added in a news release.

COVID-19 antigen tests may be less sensitive to Omicron: FDA
Rapid antigen tests for COVID-19 might be less effective at detecting the Omicron variant that is spreading rapidly across the United States, according to the Food and Drug Administration.
Early data suggest that COVID-19 antigen tests “do detect the Omicron variant but may have reduced sensitivity,” the FDA said in a statement posted Dec. 28 on its website.
The FDA is working with the National Institutes of Health’s Rapid Acceleration of Diagnostics (RADx) initiative to assess the performance of antigen tests with patient samples that have the Omicron variant.
The potential for antigen tests to be less sensitive for the Omicron variant emerged in tests using patient samples containing live virus, “which represents the best way to evaluate true test performance in the short term,” the FDA said.
Initial laboratory tests using heat-activated (killed) virus samples found that antigen tests were able to detect the Omicron variant.
“It is important to note that these laboratory data are not a replacement for clinical study evaluations using patient samples with live virus, which are ongoing. The FDA and RADx are continuing to further evaluate the performance of antigen tests using patient samples with live virus,” the FDA said.
Testing still important
The agency continues to recommend use of antigen tests as directed in the authorized labeling and in accordance with the instructions included with the tests.
They note that antigen tests are generally less sensitive and less likely to pick up very early infections, compared with molecular tests.
The FDA continues to recommend that an individual with a negative antigen test who has symptoms or a high likelihood of infection because of exposure follow-up with a molecular test to determine if they have COVID-19.
An individual with a positive antigen test should self-isolate and seek follow-up care with a health care provider to determine the next steps.
The FDA, with partners and test developers, are continuing to evaluate test sensitivity, as well as the best timing and frequency of antigen testing.
The agency said that it will provide updated information and any needed recommendations when appropriate.

Formaldehyde exposure tied to cognitive impairment
Long-term exposure to formaldehyde on the job is linked to cognitive impairment down the road, new research suggests.
In a large observational study of adults aged 45-70 years, researchers found a 17% higher risk for cognitive problems in those with occupational formaldehyde exposure – and higher risks for those with longer duration of exposure.
“The effect of formaldehyde on the brain has been previously shown mainly in animal experiments, but very few studies have been done on humans,” lead author Noemie Letellier, PhD, Institute for Neurosciences of Montpellier, University of Montpellier (France), said in an interview.
“Our results show that being or having been occupationally exposed to formaldehyde is associated with cognitive impairment in a relatively young population,” Dr. Letellier said.
The findings were published online Dec. 22, 2021, in the journal Neurology.
Dose-effect relationship
The investigators assessed a representative sample of 75,322 adults in France (median age, 57.5 years; 53% women). All were part of the CONSTANCES cohort, an observational cohort with a focus on occupational and environmental factors.
A total of 6,026 participants (8%) were exposed to formaldehyde during their careers. Their occupations included nurses, caregivers, medical technicians, workers in the textile, chemistry and metal industries, carpenters, and cleaners.
The researchers calculated lifetime formaldehyde exposure using a French job-exposure matrix created to estimate a person’s exposure to potential health hazards in different occupations.
Individuals were divided into three equal groups according to their years of exposure to formaldehyde. “Low” was considered to be 6 or fewer years of exposure, “medium” was 7-21 years, and “high” was 22 or more years.
Participants were also split into three groups according to their cumulative exposure (total lifetime formaldehyde exposure based on the probability, intensity, and frequency of exposure).
Prevention efforts needed
After adjusting for age, sex, education and other confounders, participants exposed to formaldehyde were at higher risk for global cognitive impairment (adjusted relative risk, 1.17; 95% confidence interval, 1.1-1.2).
Longer duration of exposure and high cumulative lifetime exposure were associated with worse cognitive impairment, “with a dose-effect relationship for exposure duration,” the researchers reported.
Those exposed to formaldehyde for 22 years or more had a 21% higher risk of global cognitive impairment and workers with the highest cumulative exposure had a 19% higher risk of cognitive impairment, compared with workers with no exposure.
Although workers with recent exposure showed higher cognitive impairment, “time may not fully attenuate formaldehyde-associated cognitive deficits, especially in highly exposed but also in moderately exposed workers,” the researchers wrote.
They caution that their findings only show an association and does not prove that exposure to formaldehyde causes cognitive impairment.
Nonetheless, Dr. Letellier encourages health care providers to “be aware of lifetime occupational exposure to target prevention efforts to the identified occupational groups.” This especially includes the care sector where the most people are exposed to formaldehyde, such as nurses, caregivers, and medical technicians.
“Despite the restrictions on the use of formaldehyde due to the better knowledge of its toxicity, especially its carcinogenic effect, formaldehyde is still widely used in many sectors. These results encourage prevention efforts to further limit worker exposure to formaldehyde,” Dr. Letellier said.
Relevant to health care workers
Commenting on the study, Shaheen E. Lakhan, MD, PhD, a neurologist in Newton, Mass., said in an interview that exposure to some degree of formaldehyde is found in every home and workplace, “from the floors to furniture.”
“If you have cigarette smoke in the environment, your exposure rises sharply. When limiting your exposure, it’s not only cancer that you are preventing, but also your brain health,” added Dr. Lakhan, who was not involved with the research.
He said the disturbances in cognitive function noted in the current study were “particularly relevant to health care workers, given the use of formaldehyde in sterilization, tissue pathology processing, and embalming.”
“Interestingly, with only past exposure, there seems to be some degree of cognitive recovery,” but it does not return to a level before any exposure when corrected for age and other factors, Dr. Lakhan said.
Some caveats should also be noted, he pointed out. The study included a French population, but regulators such as the U.S. Occupational Safety and Health Administration and the California Office of Environmental Health Hazard Assessment have strict standards on formaldehyde use in a variety of work settings.
On the flip side, given the COVID-19 pandemic, there has been greater use of chemical disinfectants in and out the workplace, some of which contain formaldehyde, Dr. Lakhan said.
In addition, he noted the study assessed data from 1950 to 2018, so prepandemic.
“A word of advice from a brain doc: Check with your employer on the level of occupational exposure to formaldehyde, heavy metals, and other toxic substances – and cross-reference with your local environmental standards,” Dr. Lakhan concluded.
The research was supported by a grant from the French Agency for Food, Environmental, and Occupational Health & Safety. The investigators and Dr. Lakhan disclosed no relevant financial relationships.

“Despite the restrictions on the use of formaldehyde due to the better knowledge of its toxicity, especially its carcinogenic effect, formaldehyde is still widely used in many sectors. These results encourage prevention efforts to further limit worker exposure to formaldehyde,” Dr. Letellier said.
Relevant to health care workers
Commenting on the study, Shaheen E. Lakhan, MD, PhD, a neurologist in Newton, Mass., said in an interview that exposure to some degree of formaldehyde is found in every home and workplace, “from the floors to furniture.”
“If you have cigarette smoke in the environment, your exposure rises sharply. When limiting your exposure, it’s not only cancer that you are preventing, but also your brain health,” added Dr. Lakhan, who was not involved with the research.
He said the disturbances in cognitive function noted in the current study were “particularly relevant to health care workers, given the use of formaldehyde in sterilization, tissue pathology processing, and embalming.”
“Interestingly, with only past exposure, there seems to be some degree of cognitive recovery,” but it does not return to a level before any exposure when corrected for age and other factors, Dr. Lakhan said.
Some caveats should also be noted, he pointed out. The study included a French population, but regulators such as the U.S. Occupational Safety and Health Administration and the California Office of Environmental Health Hazard Assessment have strict standards on formaldehyde use in a variety of work settings.
On the flip side, given the COVID-19 pandemic, there has been greater use of chemical disinfectants in and out the workplace, some of which contain formaldehyde, Dr. Lakhan said.
In addition, he noted the study assessed data from 1950 to 2018, so prepandemic.
“A word of advice from a brain doc: Check with your employer on the level of occupational exposure to formaldehyde, heavy metals, and other toxic substances – and cross-reference with your local environmental standards,” Dr. Lakhan concluded.
The research was supported by a grant from the French Agency for Food, Environmental, and Occupational Health & Safety. The investigators and Dr. Lakhan disclosed no relevant financial relationships.

Fish oil: ‘No net benefit’ for depression prevention?
Fish oil supplementation does not help prevent depression or boost mood, new research suggests.
The VITAL-DEP study included more than 18,000 participants. Among adults aged 50 years or older free of clinically relevant depressive symptoms at baseline, long-term use of marine omega-3 fatty acid (omega-3) supplements did not reduce risk for depression or clinically relevant depressive symptoms — or make a difference in the quality of mood.
“While a small increase in risk of depression was inside the statistical margin of significance, there was no harmful or beneficial effect of omega-3 on the overall course of mood during the roughly 5 to 7 years of follow-up,” lead author Olivia I. Okereke, MD, Massachusetts General Hospital and Harvard Medical School, Boston, told Medscape Medical News.
“The takeaway from our study is that there is no net benefit of long-term use of daily omega-3 fish oil supplements for preventing depression or boosting mood,” Okereke said.
The findings were published online Dec. 21 in JAMA.
Assessing general population risk
For many years, experts have recommended omega-3 supplements for reduction in depression recurrence in some high-risk patients, Okereke noted.
“However, there are no guidelines related to the use of omega-3 supplements for preventing depression in the general population. Therefore, we undertook this study to provide clarity in the issue,” she said.
The VITAL-DEP study enrolled 18,353 older adults (mean age, 67.5 years; 49% women). Of these, 16,657 were at risk for incident depression, defined as having no previous history of depression; and 1696 were at risk for recurrent depression, defined as having a history of depression but not having undergone treatment for depression within the past 2 years.
Roughly half the participants were randomly assigned to receive marine omega-3 fatty acids (1 g/d of fish oil, including 465 mg of eicosapentaenoic acid [EPA] and 375 mg of docosahexaenoic acid [DHA]) and the other half to matching placebo for an average of 5.3 years.
“Because of the large sample size and long follow-up, we were able to test the effects of daily omega-3 fish oil supplements on universal prevention of depression in the adult population,” Okereke said.
No significant benefit
Results showed risk for depression or clinically relevant depressive symptoms (total of incident and recurrent cases) was not significantly different between the omega-3 group and the placebo group.
The omega-3 group had 651 depression or clinically relevant depressive symptom events (13.9 per 1000 person-years), and the placebo group had 583 depression or clinically relevant depressive symptom events (12.3 per 1000 person-years). The hazard ratio was 1.13 (95% CI, 1.01 - 1.26; P = .03).
There were also no significant between-group differences in longitudinal mood scores. The mean difference in change in 8-item Patient Health Questionnaire (PHQ-8) score was 0.03 points (95% CI, −0.01 to 0.07; P = .19).
“Patients, physicians, and other clinicians should understand that there are still many reasons for some people, under the guidance of their health care providers, to take omega-3 fish oil supplements,” Okereke noted.
“These supplements increasingly have been found to have benefits for cardiac disease prevention and treatment of inflammatory conditions, in addition to being used for management of existing depressive disorders in some high-risk patients,” she said.
“However, the results of our study indicate there is no reason for adults in the general population to be taking daily omega-3 fish oil supplements solely for the purpose of preventing depression or for maintaining a positive mood,” she added.
Okereke noted, however, that the VITAL-DEP study used 1 g/day of omega-3 fatty acids and there may be a greater benefit from taking higher doses, such as 4 g/day.
Cautionary notes
Commenting on the study for Medscape Medical News, Kuan-Pin Su, MD, PhD, chief of the Department of General Psychiatry, China Medical University, Taichung, Taiwan, highlighted some of the limitations cited by the investigators.
First, depression or depressive symptoms were defined using self-rating scales, which are “convenient to screen for depressive disorders, but a high score obtained on a self-rating scale does not necessarily indicate the presence of depressive psychopathology,” said Su, who was not involved with the research.
He also noted that use of 465 mg of EPA and 375 mg of DHA in VITAL-DEP “might be too low” to have an impact.
Finally, Su said it is “very important to also address the potential for type I error, which makes the secondary and subgroup analyses less reliable.”
VITAL-DEP was supported by a grant from the National Institute of Mental Health. Pronova BioPharma donated the fish oil and matching placebo. Okereke reported receiving royalties from Springer Publishing. Su is a founding committee member of the International Society for Nutritional Psychiatry Research, the board director of the International Society for the Study of Fatty Acids, and an associate editor of the journal Brain, Behavior, and Immunity.

FDA grants new indication to lumateperone (Caplyta) for bipolar depression
The Food and Drug Administration has expanded approval of lumateperone (Caplyta) to include treatment of adults with depressive episodes associated with bipolar I and II disorder, as monotherapy or adjunctive therapy with lithium or valproate.
This makes lumateperone the only FDA-approved drug for this indication.
“The efficacy, and favorable safety and tolerability profile, make Caplyta an important treatment option for the millions of patients living with bipolar I or II depression and represents a major development for these patients,” Roger McIntyre, MD, professor of psychiatry and pharmacology, University of Toronto, and head of the mood disorders psychopharmacology unit, said in a company news release.
Lumateperone was first approved by the FDA in 2019 for the treatment of adults with schizophrenia.
‘Positioned to launch immediately’
that showed treatment with lumateperone, alone or with lithium or valproate, significantly improved depressive symptoms for patients with major depressive episodes associated with bipolar I and bipolar II disorders.
In these studies, treatment with a 42-mg once-daily dose was associated with significantly greater improvement from baseline in Montgomery-Åsberg Depression Rating Scale score versus placebo.
Lumateperone also showed a statistically significant improvement in the key secondary endpoint relating to clinical global impression of bipolar disorder.
Somnolence/sedation, dizziness, nausea, and dry mouth were the most commonly reported adverse events associated with the medication. Minimal changes were observed in weight and vital signs and in results of metabolic or endocrine assessments. Incidence of extrapyramidal symptom–related events was low and was similar to those with placebo.
Sharon Mates, PhD, chairman and CEO of Intra-Cellular Therapies, noted in the same press release that the company is “positioned to launch immediately and are excited to offer Caplyta to the millions of patients living with bipolar depression.”

Class I recall of percutaneous thrombolytic device
Arrow International, a subsidiary of Teleflex, has recalled a total of 3,241 Arrow-Trerotola over-the-wire 7FR percutaneous thrombolytic device (PTD) kits because of the risk of the orange inner lumen of the catheter’s tip component separating from the basket.
The U.S. Food and Drug Administration has identified this as a Class I recall, the most serious type, because of the potential for serious injury or death.
The recalled kits include a rotatable catheter with an outer sheath and an inner cable with a self-expanding basket. The Arrow-Trerotola PTD catheter is used with the Arrow rotator drive unit to remove clots in patients with arteriovenous fistulas and synthetic dialysis grafts.
“If the orange inner lumen separates from the basket, it may fracture and detach and block the blood vessel(s),” the FDA says in the recall notice posted on the FDA website.
“If the orange inner lumen detaches from the basket, health consequences depend upon where the fractured tip component embolizes. If the embolization is local to the treatment target site, retrieval may be attempted, requiring an additional intervention and consequent delay of therapy,” the agency notes.
“In some cases, the embolization could be central or possibly even to the heart or pulmonary arteries. This may lead to serious adverse events such as vessel damage, need for additional medical procedures, or possibly death,” the agency says.
To date, there have been seven complaints and no injuries or deaths reported for this device.
The recalled devices were distributed in the United States between Nov. 1, 2019, and July 31, 2021. Product codes and lot numbers pertaining to the devices are listed on the FDA website.
Teleflex has sent an urgent field safety notice to customers requesting that they check inventory for affected product and remove and quarantine all recalled product.
Customers are also asked to complete the enclosed acknowledgement form and fax it to 1-855-419-8507 (attention: customer service) or e-mail the form to [email protected].
Customers with recalled product service will be contacted by a company representative with instructions for returning any recalled products.
Customers who have questions about this recall should contact Teleflex customer service by phone at 1-866-396-2111, by fax at 1-855-419-8507, or by email at [email protected].
Health care providers can report adverse reactions or quality problems they experience using these devices to the FDA’s MedWatch program.
