Major Depressive Disorder

Primary care providers (PCPs) are addressing an increasing number of mental health visits, requiring collaborative and innovative approaches to providing psychiatric care.

This growth in the number of patients needing behavioral health–related care is likely driven by multiple factors, including a shortage of mental health care providers, an increasing incidence of psychiatric illness, and destigmatization of mental health in general, suggested Swetha P. Iruku, MD, MPH, associate professor of family medicine and community health at the University of Pennsylvania and Penn Medicine family physician in Philadelphia.

The Centers for Disease Control and Prevention noted that “the COVID-19 pandemic has been associated with mental health challenges related to the morbidity and mortality caused by the disease and to mitigation activities, including the impact of physical distancing and stay-at-home orders,” in a Morbidity and Mortality Weekly Report.

From June 24 to 30, 2020, U.S. adults reported considerably elevated adverse mental health conditions associated with COVID-19, and symptoms of anxiety disorder and depressive disorder climbed during the months of April through June of the same year, compared with the same period in 2019, they wrote.

Even before the pandemic got underway, multiple studies of national data published this year suggested mental issues were on the rise in the United States. For example, the proportion of adult patient visits to primary care providers that addressed mental health concerns rose from 10.7% to 15.9% from 2006 to 2018, according to research published in Health Affairs. Plus, the number and proportion of pediatric acute care hospitalizations because of mental health diagnoses increased significantly between 2009 and 2019, according to a paper published in JAMA.

“I truly believe that we can’t, as primary care physicians, take care of someone’s physical health without also taking care of their mental health,” Dr. Iruku said in an interview. “It’s all intertwined.”

To rise to this challenge, PCPs first need a collaborative mindset, she suggested, as well as familiarity with available resources, both locally and virtually.

This article examines strategies for managing mental illness in primary care, outlines clinical resources, and reviews related educational opportunities.

In addition, clinical pearls are shared by Dr. Iruku and five other clinicians who provide or have provided mental health care to primary care patients or work in close collaboration with a primary care practice, including a clinical psychologist, a nurse practitioner licensed in psychiatric health, a pediatrician, and a licensed clinical social worker.
 

Build a network

Most of the providers interviewed cited the importance of collaboration in mental health care, particularly for complex cases.

“I would recommend [that primary care providers get] to know the psychiatric providers [in their area],” said Jessica Viton, DNP, FNP, PMHNP, who delivers mental health care through a community-based primary care practice in Colorado which she requested remain anonymous.

Dr. Iruku suggested making an in-person connection first, if possible.

“So much of what we do is ‘see one, do one, teach one,’ so learn a little bit, then go off and trial,” she said. “[It can be valuable] having someone in your back pocket that you can contact in the case of an emergency, or in a situation where you just don’t know how to tackle it.”
 

Screen for depression and anxiety

William J. Sieber, PhD, a clinical psychologist, director of integrated behavioral health, and professor in the department of family medicine and public health and the department of psychiatry at the University of California, San Diego, said primary care providers should screen all adult patients for depression and anxiety with the Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder Assessment (GAD-7), respectively.

To save time, he suggested a cascading approach.

“In primary care, everybody’s in a hurry,” Dr. Sieber said. “[With the cascading approach,] the first two items [from each questionnaire] are given, and if a person endorses either of those items … then they are asked to complete the other items.”

Jennifer Mullally, MD, a pediatrician at Sanford Health in Fargo, N.D., uses this cascading approach to depression and anxiety screening with all her patients aged 13-18. For younger kids, she screens only those who present with signs or symptoms of mental health issues, or if the parent shares a concern.

This approach differs slightly from U.S. Preventive Services Task Force recommendations, which suggest screening for anxiety in patients aged 8-18 years and depression in patients aged 12-18 years.
 

Use other screening tools only as needed

Dr. Sieber, the research director for the division of family medicine at UC San Diego, collaborates regularly with primary care providers via hallway consultations, by sharing cases, and through providing oversight of psychiatric care at 13 primary care practices within the UC San Diego network. He recommended against routine screening beyond depression and anxiety in the primary care setting.

“There are a lot of screening tools,” Dr. Sieber said. “It depends on what you’re presented with. The challenge in primary care is you’re going to see all kinds of things. It’s not like running a depression clinic.”

Other than the PHQ-9 and GAD-7, he suggested primary care providers establish familiarity with screening tools for posttraumatic stress disorder and attention-deficit/hyperactivity disorder, noting again that these should be used only when one of the conditions is already suspected.

Dr. Mullally follows a similar approach with her pediatric population. In addition to the GAD-7, she investigates whether a patient has anxiety with the Screen for Child Anxiety Related Disorders (SCARED). For depression, she couples the PHQ-9 with the Columbia Suicide Severity Rating Scale.

While additional screening tools like these are readily available online, Dr. Viton suggested that they should be employed only if the provider is trained to interpret and respond to those findings, and only if they know which tool to use, and when.

For example, she has recently observed PCPs diagnosing adults with ADHD using a three-question test, when in fact a full-length, standardized instrument should be administered by a provider with necessary training.

She also pointed out that bipolar disorder continues to be underdiagnosed, possibly because of providers detecting depression using a questionnaire like the PHQ-9, while failing to inquire about manic episodes.
 

Leverage online resources

If depression is confirmed, Dr. Iruku often directs the patient to the Mayo Clinic Depression Medication Choice Decision Aid. This website steers patients through medication options based on their answers to a questionnaire. Choices are listed alongside possible adverse effects.

For clinician use, Dr. Iruku recommended The Waco Guide to Psychopharmacology in Primary Care, which aids clinical decision-making for mental illness and substance abuse. The app processes case details to suggest first-, second-, and third-line pharmacotherapies, as well as modifications based on patient needs.

Even with tools like these, however, a referral may be needed.

“[Primary care providers] may not be the best fit for what the patient is looking for, from a mental health or behavioral standpoint,” Dr. Sieber said.

In this case, he encourages patients to visit Psychology Today, a “quite popular portal” that helps patients locate a suitable provider based on location, insurance, driving radius, and mental health concern. This usually generates 10-20 options, Dr. Sieber said, although results can vary.

“It may be discouraging, because maybe only three [providers] pop up based on your criteria, and the closest one is miles away,” he said.
 

Consider virtual support

If no local psychiatric help is available, Dr. Sieber suggested virtual support, highlighting that “it’s much easier now than it was 3 or 4 years ago” to connect patients with external mental health care.

But this strategy should be reserved for cases of actual need instead of pure convenience, cautioned Dr. Viton, who noted that virtual visits may fail to capture the nuance of an in-person meeting, as body language, mode of dress, and other clues can provide insights into mental health status.

“Occasionally, I think you do have to have an in-person visit, especially when you’re developing a rapport with someone,” Dr. Viton said.

Claire McArdle, a licensed clinical social worker in Fort Collins, Colo., noted that virtual care from an outside provider may also impede the collaboration needed to effectively address mental illness.

In her 11 years in primary care at Associates in Family Medicine, Ms. McArdle had countless interactions with colleagues seeking support when managing a complex case. “I’m coaching providers, front desk staff, and nursing staff on how to interact with patients [with] behavioral health needs,” she said, citing the multitude of nonmedical factors that need to be considered, such as family relationships and patient preferences.

These unscheduled conversations with colleagues throughout the day are impossible to have when sharing a case with an unknown, remote peer.

Ms. McArdle speaks from experience. She recently resigned from Associates in Family Medicine to start her own private therapy practice after her former employer was acquired by VillageMD, a national provider that terminated employment of most other social workers in the practice and began outsourcing mental health care to Mindoula Health, a virtual provider.

Dr. Sieber offered a similar perspective on in-person collaboration as the psychiatric specialist at his center. He routinely offers on-site support for both providers and patients, serving as “another set of eyes and ears” when there is a concern about patient safety or directly managing care when a patient is hospitalized for mental illness.

While virtual solutions may fall short of in-person management, they can offer care at a scale and cost impossible through traditional practice.

This could even be free. Zero-cost, automated software now allows individuals who are uninsured or unable to afford care at least one avenue to manage their mental health concerns.

For example, Bliss is a free, 8-session, interactive online therapy program for depression that was created by the Centre for Interactive Mental Health Solutions. The program offers a tool for monitoring mood and quizzes to test understanding of personal mental health management, among other features.

More advanced programs are emerging as artificial intelligence (AI) enables dialogues between humans and machines. This is the case with Woebot, an app that asks the user about their mood throughout the day, and responds with evidence-based strategies for managing concerns, all for free at press time.
 

Keep learning

A range of educational options and professional resources are available for primary care providers who would like to improve their knowledge of mental health care. These include formal fellowships in primary care psychiatry/behavioral health integration, free mental health webinars, and various other opportunities.

Eric Eschweiler, DNP, APRN, FNP-C, PHN, completed the University of California, Irvine, Train New Trainers (TNT) Primary Care Psychiatry (PCP) Fellowship in 2016, when he was working as a solo nurse practitioner.

“I was drowning in practice,” said Dr. Eschweiler, director of nursing and public health outreach services at Riverside-San Bernardino County Indian Health, Grand Terrace, Calif., in an interview. “I was a solo NP. There was no physician on site. We were seeing a lot of [individuals with] schizoaffective [disorder] in downtown San Bernardino, the homeless, unhoused – a lot of substance use. I felt I needed to have the skills to be able to treat them effectively. That’s what the fellowship did.”

The skills Dr. Eschweiler learned from participating in his fellowship allowed him to manage more cases of mental illness without need for referral. When a referral was needed for a complex or severe case, he had the confidence to bridge care and collaborate more effectively with psychiatric specialists.

“It was awesome, because we were able to communicate using the same language,” Dr. Eschweiler said of these collaborations. “It’s [about] talking that same language, starting those initial treatments, and then moving forward with specialty care, and vice versa. [Psychiatric specialists] would send me patients that needed medical care because of the types of medications they were taking. And I was then very well aware of those side effects and other issues that might come up from those treatments. So it’s a two-way street.”

Dr. Eschweiler was so impressed by his fellowship that he has since ushered multiple providers through the program since transitioning to an administrative role as director of nursing.

In Fargo, where psychiatric care is sparse and wait times for referral can be months long, Dr. Mullally, like Dr. Eschweiler, knew that she needed more training in mental health.

“I don’t feel like we get enough training in residency,” Dr. Mullally said. “So you do need to look at your options for further CME.”

Out of several CME courses she has taken to further her understanding of pediatric psychiatry, Dr. Mullally recommended The Reach Institute above all others, as their courses involve in-depth discussions and valuable handouts, particularly for medication selection.

“I think that a lot of the other CMEs tend to involve a lot more PowerPoint presentations,” Dr. Mullally said. “And you don’t necessarily leave with a lot of good documents. I still use my Reach handouts. I have them sitting right next to me. I use them every single day.”

Providers interested in The Reach Institute, however, should be prepared to invest both time and money, she added, citing a 2-3 day commitment, and calling it “not cheap.” To overcome these barriers, she suggested that providers get their institution to support their attendance.

For a lighter commitment, Dr. Iruku recommended the American Academy of Family Physicians CME portal, as this offers 13 online, accredited courses covering a range of topics, from adolescent health to substance abuse disorders.

Dr. Sieber suggested that primary care providers join the Collaborative Family Healthcare Association, which aims to integrate physical and behavioral health in routine practice. CFHA, of which he is a member, offers a “bevy of different resources” for interested providers, including a conference in Phoenix this October.

The interviewees disclosed no conflicts of interest.

She recently resigned from Associates in Family Medicine to start her own private therapy practice after her former employer was acquired by VillageMD, a national provider that terminated employment of most other social workers in the practice and began outsourcing mental health care to Mindoula Health, a virtual provider.

Dr. Sieber offered a similar perspective on in-person collaboration as the psychiatric specialist at his center. He routinely offers on-site support for both providers and patients, serving as “another set of eyes and ears” when there is a concern about patient safety or directly managing care when a patient is hospitalized for mental illness.

While virtual solutions may fall short of in-person management, they can offer care at a scale and cost impossible through traditional practice.

This could even be free. Zero-cost, automated software now allows individuals who are uninsured or unable to afford care at least one avenue to manage their mental health concerns.

For example, Bliss is a free, 8-session, interactive online therapy program for depression that was created by the Centre for Interactive Mental Health Solutions. The program offers a tool for monitoring mood and quizzes to test understanding of personal mental health management, among other features.

More advanced programs are emerging as artificial intelligence (AI) enables dialogues between humans and machines. This is the case with Woebot, an app that asks the user about their mood throughout the day, and responds with evidence-based strategies for managing concerns, all for free at press time.
 

Keep learning

A range of educational options and professional resources are available for primary care providers who would like to improve their knowledge of mental health care. These include formal fellowships in primary care psychiatry/behavioral health integration, free mental health webinars, and various other opportunities.

Eric Eschweiler, DNP, APRN, FNP-C, PHN, completed the University of California, Irvine, Train New Trainers (TNT) Primary Care Psychiatry (PCP) Fellowship in 2016, when he was working as a solo nurse practitioner.

“I was drowning in practice,” said Dr. Eschweiler, director of nursing and public health outreach services at Riverside-San Bernardino County Indian Health, Grand Terrace, Calif., in an interview. “I was a solo NP. There was no physician on site. We were seeing a lot of [individuals with] schizoaffective [disorder] in downtown San Bernardino, the homeless, unhoused – a lot of substance use. I felt I needed to have the skills to be able to treat them effectively. That’s what the fellowship did.”

The skills Dr. Eschweiler learned from participating in his fellowship allowed him to manage more cases of mental illness without need for referral. When a referral was needed for a complex or severe case, he had the confidence to bridge care and collaborate more effectively with psychiatric specialists.

“It was awesome, because we were able to communicate using the same language,” Dr. Eschweiler said of these collaborations. “It’s [about] talking that same language, starting those initial treatments, and then moving forward with specialty care, and vice versa. [Psychiatric specialists] would send me patients that needed medical care because of the types of medications they were taking. And I was then very well aware of those side effects and other issues that might come up from those treatments. So it’s a two-way street.”

Dr. Eschweiler was so impressed by his fellowship that he has since ushered multiple providers through the program since transitioning to an administrative role as director of nursing.

In Fargo, where psychiatric care is sparse and wait times for referral can be months long, Dr. Mullally, like Dr. Eschweiler, knew that she needed more training in mental health.

“I don’t feel like we get enough training in residency,” Dr. Mullally said. “So you do need to look at your options for further CME.”

Out of several CME courses she has taken to further her understanding of pediatric psychiatry, Dr. Mullally recommended The Reach Institute above all others, as their courses involve in-depth discussions and valuable handouts, particularly for medication selection.

“I think that a lot of the other CMEs tend to involve a lot more PowerPoint presentations,” Dr. Mullally said. “And you don’t necessarily leave with a lot of good documents. I still use my Reach handouts. I have them sitting right next to me. I use them every single day.”

Providers interested in The Reach Institute, however, should be prepared to invest both time and money, she added, citing a 2-3 day commitment, and calling it “not cheap.” To overcome these barriers, she suggested that providers get their institution to support their attendance.

For a lighter commitment, Dr. Iruku recommended the American Academy of Family Physicians CME portal, as this offers 13 online, accredited courses covering a range of topics, from adolescent health to substance abuse disorders.

Dr. Sieber suggested that primary care providers join the Collaborative Family Healthcare Association, which aims to integrate physical and behavioral health in routine practice. CFHA, of which he is a member, offers a “bevy of different resources” for interested providers, including a conference in Phoenix this October.

The interviewees disclosed no conflicts of interest.

When used as an adjunctive treatment, probiotic supplements reduce symptoms in patients with major depression, results of a randomized, placebo-controlled trial suggest.
 

By the end of the 8-week pilot study, participants who had an incomplete response to antidepressants prior to taking probiotics scored better on measures of anxiety and depression versus placebo.

“This was a pilot study, designed as an initial exploration of whether improving gut health with probiotics could act as a new pathway for supporting mood and mental health,” study investigator Viktoriya Nikolova, PhD, Institute of Psychiatry, Psychology and Neuroscience at King’s College London, said in an interview.

“While very promising and exciting, our findings are only the first step, and larger trials are needed,” she noted.

The findings were published online in JAMA Psychiatry.
 

Gut-brain axis

It is estimated that up to 60% of people taking antidepressants for major depressive disorder (MDD) do not achieve full response.

With an eye on the so-called gut-brain axis as a treatment target for depression, the researchers conducted a meta-analysis of seven randomized controlled trials (RCT) in 2021 and found that probiotics appeared effective in reducing depressive symptoms when taken alongside antidepressants. The studies in this meta-analysis either reported poor adherence rates or did not investigate how well study participants tolerated probiotics.

To further investigate, Dr. Nikolova and team launched a pilot RCT by recruiting study participants from primary and secondary health care services, and  through general advertising in London. Data were collected from September 2019 to May 2022.

They included 49 adults diagnosed with MDD with an incomplete antidepressant response, indicated by a score of greater than 13 on the Hamilton Depression Rating Scale-17 (HAMD-17).

Half of the participants were randomly assigned to receive a widely available, proprietary, 14-strain blend probiotic supplement, and half received placebo. Both groups took their study drug four times per day during the 8-week trial.

At baseline, 4 weeks, and 8 weeks, investigators assessed the participants for depression with the HAMD-17, the Inventory of Depressive Symptomatology (IDS) Self-Report, and anxiety with the Hamilton Anxiety Rating Scale (HAMA).

The majority of participants (80%) were female with a mean age of 32 years. Adherence was high, with 97% of the doses taken as required, and no adverse events were reported.

Standardized effect sizes from linear mixed models demonstrated that, when compared with the placebo group, the probiotic group had more improvement in depressive symptoms according to the HAMD-17 (week 4: SES, 0.70; 95% confidence interval, 0.01-0.98) and IDS Self Report (week 8: SES, 0.64; 95% CI, 0.03-0.87).

When compared with the placebo group, the probiotic group also experienced greater improvements in anxiety symptoms according to the HAMA (week 4: SES, 0.67; 95% CI, 0-0.95; week 8: SES, 0.79; 95% CI, 0.06-1.05).

Dr. Nikolova said a large follow-up trial is planned to further confirm the results.

Nutritional psychiatrist Drew Ramsey, MD, author of Eat to Beat Depression and Anxiety and assistant clinical professor of psychiatry at Columbia University, New York, said in an interview: “This randomized clinical trial adds to the considerable evidence that food choices impact depression outcomes.”

He further noted that, “in nutritional psychiatry, we recommend eating fermented foods as they have been shown to improve microbiome diversity and decrease markers of inflammation.”

Dr. Ramsey noted that the RCT used the equivalent colony-forming unit of a “single serving of kombucha.”

“In our clinical group and our nutritional psychiatry course for clinicians, we recommend fermented foods over probiotics as this is the most sustainable, evidence-based way to improve microbiome diversity,” said Dr. Ramsey, citing recent research by Gardner and colleagues at Stanford (Calif.) University.

“This is an industry-funded trial that adds to the evidence base but should be interpreted by patients and clinicians as promoting consumption of more kefir, kimchi, and kombucha, not that patients should take probiotics,” he said.
 

A key place for probiotics in mental health

Commenting on the study, Uma Naidoo, MD, said: “As I shared throughout my first book, This is Your Brain on Food, there is a real place for the use of probiotics in mental health, including the importance of the gut-brain connection.”

Dr. Naidoo is the director of nutritional and metabolic psychiatry at Massachusetts General Hospital and of nutritional psychiatry at the MGH Academy, both in Boston.

She noted that, when a person stops using a probiotic after trying it out, the positive changes in the gut are reversed, so “remaining consistent in taking the probiotic is important if you have found it helpful for your mood.”

Dr. Naidoo added that “each person’s gut microbiome is so unique that it is likely not every human being will have the same reaction to a probiotic.”

“Eating foods with live probiotics may also benefit gut health and, therefore, mood,” she said. The same goes with eating fermented foods with live active cultures.”

The study was funded by a Medical Research Council Industrial CASE PhD Studentship with ADM Protexin (supplier of the probiotics) as the industry partner and additional support from Freya Green. Dr. Nikolova has received grants from the Medical Research Council and ADM Protexin during the conduct of the study as well as personal fees from Janssen outside the submitted work.

TOPLINE

Mean lipid levels are similar among adolescents with and without major depressive disorder (MDD), as is the proportion of adolescents with borderline-high lipid levels.

METHODOLOGY

Teen depression is associated with an increased likelihood of experiencing cardiovascular (CV) events, with dyslipidemia being a potentially modifiable risk factor.

Only a few studies have examined the association between depression and lipids during adolescence, when confounding comorbidities such as obesity and diabetes are less common.

The study included 243 adolescents (186 with MDD and 57 healthy controls [HCs]) who were mostly female and had a mean age of 15 years.

Researchers assessed CV risk factors including body mass index (BMI), blood pressure, smoking status, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglyceride (TG), which were classified as acceptable or borderline high.

Dyslipidemia was defined as having concentration of at least one lipid outside the acceptable range.
 

TAKEAWAY

Most participants in both groups had lipid concentrations within the acceptable range.

There were no differences between study groups in mean lipid levels after adjusting for age, sex, and standardized BMI.

There were also no differences in the proportion of adolescents with borderline-high lipid concentrations.

Among youth with MDD, greater depressive symptoms were associated with higher HDL levels and a lower TG:HDL ratio after adjusting for sex, age, and standardized BMI.
 

IN PRACTICE

“Taken together, results of the current study support the need for further examination of the relationship between gender, depression, and cholesterol,” the authors write.

STUDY DETAILS

The study was conducted by Anisa F. Khalfan, Neurosciences and Mental Health research program, SickKids Research Institute, Toronto, Canada, and colleagues. It was published online in the Journal of Affective Disorders.

LIMITATIONS

The HC group was relatively small, which might have contributed to the null findings. The mean Center for Epidemiologic Studies Depression Scale for Children (CES-DC) score was 8.3 among healthy youth, compared with 37.5 among MDD youth, limiting detection of an association related to depression severity.

DISCLOSURES

The study was supported by the Lunenfeld Summer Studentship. The authors report no relevant financial relationships.

Baseline depression was significantly associated with recovered, incident, and persistent metabolic syndrome, based on data from more than 13,000 individuals.

Previous research has established a connection between metabolic syndrome and depression, but data on the increased risk for depressed individuals to develop metabolic syndrome (MetS) are lacking, wrote Lara Onofre Ferriani, PhD, of Federal University of Espírito Santo, Vitoria, Brazil, and colleagues.

“Individuals with MetS and depression have increased levels of inflammatory markers, and it is speculated that inflammation could mediate this comorbidity,” they said.

In a study published in the Journal of Psychiatric Research, the investigators reviewed data from 13,883 participants in the Brazilian Longitudinal Study of Adult Health; all were civil servants at universities in Brazil. The participants ranged from 35 to 74 years of age, with a mean age of 51.9 years; 54.3% were women; and 52.4% were white; the mean follow-up period was 3.8 years.

The primary outcome was the association between depression diagnosis and severity on components of MetS at baseline and over a 4-year period. Participants were classified by MetS trajectory as recovered, incident, or persistent, and classified by depression status as without depression or with a mild, moderate, or severe current depressive episode. Depression status was based on the Clinical Interview Schedule Revised. MetS components and diagnosis were based on the National Cholesterol Education Program Adult Treatment Panel III.

In a logistic regression analysis, baseline depression was positively associated with recovered, incident, and persistent MetS (odds ratios, 1.59, 1.45, and 1.70, respectively).

Depression at baseline also was significantly associated with separate components of MetS: large waist circumference, high triglycerides, low high-density lipoprotein cholesterol, and hyperglycemia, with odds ratios of 1.47, 1.23, 1.30, and 1.38, respectively.

Although not seen at baseline, a significant positive association between baseline depression and the presence of three or more MetS components was noted at follow-up, with a positive dose-response effect, the researchers wrote in their discussion.

Not all associations were statistically significant, but this was mainly because of the small number of cases of moderate and severe depression, they said. However, the magnitude of associations was greater in severe depression, when compared with moderate and mild, which suggests that the risk of MetS may be higher in this population, they added.

The study findings were limited by several factors including the possible misclassification of depression, inability to differentiate among depressive subtypes, and the potential lack of generalizability to other populations beyond Brazilian civil servants, the researchers noted.

However, the results were strengthened by the large sample size and support the role of depression as a risk factor for MetS, they said. More research is needed to determine a bidirectional relationship and to assess the trajectory of depression after MetS develops, but the findings “highlight the need to investigate and manage metabolic and cardiovascular alterations in the presence of depression in clinical settings,” they concluded.

The study was supported by the Brazilian Ministry of Health (Science and Technology Department) and the Brazilian Ministry of Science, Technology and Innovation FINEP and CNPq, and by the Coordenaçaõ de Aperfeiçoamento de Pessoal de Nível Superior – Brasil (CAPES). The researchers had no financial conflicts to disclose.

The participants ranged from 35 to 74 years of age, with a mean age of 51.9 years; 54.3% were women; and 52.4% were white; the mean follow-up period was 3.8 years.

The primary outcome was the association between depression diagnosis and severity on components of MetS at baseline and over a 4-year period. Participants were classified by MetS trajectory as recovered, incident, or persistent, and classified by depression status as without depression or with a mild, moderate, or severe current depressive episode. Depression status was based on the Clinical Interview Schedule Revised. MetS components and diagnosis were based on the National Cholesterol Education Program Adult Treatment Panel III.

In a logistic regression analysis, baseline depression was positively associated with recovered, incident, and persistent MetS (odds ratios, 1.59, 1.45, and 1.70, respectively).

Depression at baseline also was significantly associated with separate components of MetS: large waist circumference, high triglycerides, low high-density lipoprotein cholesterol, and hyperglycemia, with odds ratios of 1.47, 1.23, 1.30, and 1.38, respectively.

Although not seen at baseline, a significant positive association between baseline depression and the presence of three or more MetS components was noted at follow-up, with a positive dose-response effect, the researchers wrote in their discussion.

Not all associations were statistically significant, but this was mainly because of the small number of cases of moderate and severe depression, they said. However, the magnitude of associations was greater in severe depression, when compared with moderate and mild, which suggests that the risk of MetS may be higher in this population, they added.

The study findings were limited by several factors including the possible misclassification of depression, inability to differentiate among depressive subtypes, and the potential lack of generalizability to other populations beyond Brazilian civil servants, the researchers noted.

However, the results were strengthened by the large sample size and support the role of depression as a risk factor for MetS, they said. More research is needed to determine a bidirectional relationship and to assess the trajectory of depression after MetS develops, but the findings “highlight the need to investigate and manage metabolic and cardiovascular alterations in the presence of depression in clinical settings,” they concluded.

The study was supported by the Brazilian Ministry of Health (Science and Technology Department) and the Brazilian Ministry of Science, Technology and Innovation FINEP and CNPq, and by the Coordenaçaõ de Aperfeiçoamento de Pessoal de Nível Superior – Brasil (CAPES). The researchers had no financial conflicts to disclose.
 

Patients with “treatment-resistant depression” may be taking other medications with side effects that interfere with antidepressant efficacy.

Investigators studied over 800 patients who were taking antidepressants for major depressive disorder (MDD) and found that close to two-thirds were taking at least one nonpsychiatric medication with potential depressive symptom side effects (PDSS), more than 30% were taking two or more such medications, and 20% at least three such medications.

These medications, which included antihypertensive medications and corticosteroids, among others, were associated with higher odds of moderate-to-severe depressive symptoms, compared with medications without PDSS.

“When evaluating the reasons for inadequate response to treatment for depression, clinicians should consider whether their patient is also receiving a nonpsychiatric medication with a potential for depressive symptom side effects,” study investigator Mark Olfson, MD, MPH, Elizabeth K. Dollard professor of psychiatry, medicine, and law and professor of epidemiology, Columbia University Irving Medical Center, New York, said in an interview.

Previous research limited

“In earlier research, we found that people who were taking medications with a potential to cause depressive symptom side effects were at increased risk of depression, especially those adults who were taking more than one of these medications,” said Dr. Olfson.

This finding led Dr. Olfson and his team to “wonder whether the risks of depressive symptoms associated with these medications extended to people who were being actively treated with antidepressants for depression.”

To investigate, they turned to the National Health and Nutrition Examination Survey (NHANES) – a nationally representative cross-sectional survey of the United States general population.

The study was based on the 2013-2014, 2015-2016, and 2017-2018 waves and included 885 adults who reported using antidepressant medications for greater than or equal to 6 weeks for depression and whose depression could be ascertained.

Prescription medications with PDSS were identified through Micromedex, whose accuracy is “established” and primarily based on the U.S. Food and Drug Administration’s labeled side effects.

Nonantidepressant psychiatric medications and medications for Alzheimer’s disease or substance use disorders were not included in the analysis.

Antidepressant-treated MDD was defined as taking an antidepressant for MDD for greater than or equal to 6 weeks. Depressive symptoms were ascertained using the Patient Health Questionnaire-9 (PHQ-9) with a score of less than 5 representing no/minimal depressive symptoms and a score of greater than or equal to 10 indicating moderate/severe symptoms.

Other variables included self-reported sex, age, race/ethnicity, income, education, health insurance, and common chronic medical conditions such as hypertension, arthritis, lung disease, diabetes mellitus, thyroid disease, cancer, heart disease, liver disease, stroke, and congestive heart failure.
 

Recovery interrupted

Of the patients in the study treated with antidepressants, most were female, greater than or equal to 50 years, non-Hispanic White, and with a college education (70.55, 62.0%, 81.7%, and 69.4%, respectively).

Selective serotonin reuptake inhibitors were used by 67.9% of participants with MDD. Most had been on the same antidepressant medication for a “long time,” the authors report, with 79.2% and 67.8% taking them for greater than 1 year and greater than 2 years, respectively.

Despite the large number of patients on antidepressants, only 43.0% scored in the no/minimal symptoms range, based on the PHQ-9, while 28.4% scored in the moderate/severe range.

Most patients (85%) took at least one medication for medical conditions, with the majority medications with PDSS: 66.7% took at least one medication with PDSS, 37.3% took at least two, 21.6% took at least three, 10.7% took at least four, and 4.9% took at least five.

Almost 75% were using greater than or equal to 1 medication without PDSS, and about 50% were using greater than 1.

The number of medications with PDSS was significantly associated with lower odds of no/minimal depressive symptoms (AOR, 0.75 [95% CI, 0.64-0.87]; P < .001) and higher odds of moderate/severe symptoms (AOR, 1.14 [1.004-1.29]; P = .044).

“The predicted probability of no/minimal symptoms in those taking 5 medications with PDSS was less than half the predicted probability in those taking no medications with PDSS (0.23 vs. 0.52),” the authors report.

Conversely, the predicted probability of moderate/severe symptoms was ~50% higher in individuals taking 5 versus 0 medications with PDSS (0.36 vs. 0.24).

No corresponding associations were found for medications without PDSS.

The results were even stronger when the researchers repeated their adjusted regression analyses to focus on the 10 individual medications most associated with the severity of depressive symptoms. These were omeprazole, gabapentin, meloxicam, tramadol, ranitidine, baclofen, oxycodone, tizanidine, propranolol, and morphine, with an AOR of 0.42 [0.30-0.60] for no/minimal symptoms and 1.68 [1.24-2.27] for moderate/severe symptoms.

“Many widely prescribed medications, from antihypertensives, such as atenolol and metoprolol to corticosteroids, such as dexamethasone and triamcinolone, are associated with depression side effects,” said Dr. Olfson.

“These medications could interfere with recovery from depression. When available, consideration should be given to selecting a substitute with lower risk for depressive symptoms,” he said.
 

Role in treatment-resistant depression

In a comment, Dima Qato, PharmD, MPH, PhD, Hygeia Centennial chair and associate professor, University of Southern California School of Pharmacy, Los Angeles, said the study “is an important reminder that the use of medications with depressive symptoms side effects is increasingly common and may contribute to delays in responsiveness or worsen depressive symptoms among individuals being treated for depression.”

TOPLINE

Patients who received zuranolone 50 mg/d demonstrated significantly greater improvement in depressive symptoms than those who received placebo, with a rapid onset of effect.

METHODOLOGY

The Food and Drug Administration has accepted filing of a new drug application for zuranolone, a neuroactive steroid that targets g-aminobutyric acid type A receptors (GABAAR), for the treatment of major depressive disorder (MDD) and postpartum depression.

The study included 543 mostly White female patients with MDD. The mean age of the patients was 40 years. Participants were randomly assigned to receive oral zuranolone 50 mg or placebo once daily for 14 days.

About 30% of patients were taking an antidepressant.

The primary endpoint was change in Hamilton Depression Rating Scale (HAM-D) score at day 15.
 

TAKEAWAY

The zuranolone group showed significantly greater improvement in depressive symptoms at 15 days compared with the placebo group (least square mean [LSM] change on HAM-D, –14.1, vs. –12.3; P = .01; Cohen’s d = 0.23).

Improvements were observed on day 3, the earliest assessment, and were sustained at all subsequent visits during the treatment and follow-up period (through day 42).

Results favored zuranolone regardless of the use of antidepressant therapies.

Patients with anxiety who received the active drug experienced improvement in anxiety symptoms compared to the patients who received placebo.

The drug was well tolerated, and there were no new safety findings. The most common treatment-emergent adverse events were somnolence and headache. There was no weight gain, sexual dysfunction, withdrawal symptoms, or increased suicidal ideation or behavior.
 

IN PRACTICE

The study adds to evidence suggesting zuranolone is a promising novel therapy for treating MDD, the authors noted.

STUDY DETAILS

The study was conducted by Anita H. Clayton, MD, department of psychiatry and neurobehavioral sciences, University of Virginia, Charlottesville, and colleagues. It was published online May 3 in The American Journal of Psychiatry.

LIMITATIONS

The study was short term, and the patient population was severely depressed at study entry, which may limit application to those with mild or moderate symptoms. There was a robust placebo response, possibly partly due to the COVID-19 pandemic, when there was an increase in depressive symptoms in the U.S. population, and so frequent in-person visits may have led to an improvement in symptoms even if the patient was receiving placebo.

DISCLOSURES

The study was funded by Sage Therapeutics and Biogen.

The B vitamin, L-methylfolate (LMF) can be an effective adjunctive treatment for patients with major depressive disorder (MDD) with an inadequate response to antidepressants, new research suggests.

The investigators analyzed six studies and found support for adjunctive use of LMF with patients with MDD not responding to antidepressant monotherapy. Treatment response was highest in those with obesity and inflammatory biomarkers.

Vladimir Maletic

“If clinicians try LMF on their patients with treatment-resistant depression, the treatment is very robust in patients who have high BMI [body mass index] or inflammatory biomarkers, and it’s worth a try even in patients who don’t have these indicators, since it’s safe and well tolerated, with no downside,” study investigator Vladimir Maletic, MD, MS, clinical professor of psychiatry and behavioral science, University of South Carolina, Greenville, said in an interview.

The study was published online in the Journal of Clinical Psychiatry.
 

‘Shortcut’ to the brain

A considerable percentage of patients with MDD fail to achieve an adequate response to treatment, the authors wrote.

Previous research shows benefits of folate (vitamin B9) and other B vitamins in the pathophysiology and treatment of depression.

Folate is available in several forms, including LMF, which differs from dietary folate and synthetic folic acid supplements because it’s a reduced metabolite that readily crosses the blood-brain barrier.

“This is a ‘shortcut’ that gets directly to the brain, especially in those with higher BMI or inflammatory indicators, allowing their antidepressant to work better,” Dr. Maletic said.

LMF is available as a prescription medical food and approved for the clinical dietary management of patients with MDD.

The authors wanted to understand the potential role of LMF in treating patients with MDD with insufficient response to current antidepressant therapy.

They analyzed six studies:

• Two multicenter, randomized, double-blind, placebo-controlled sequential parallel trials for patients with SSRI-resistant MDD (n = 148 and n = 75).
• A 12-month open-label extension trial of the two randomized, controlled trials (n = 68).
• A retrospective cohort study evaluating patients previously prescribed LMF (n = 554).
• Two post hoc exploratory analyses of the second randomized, controlled trial, stratifying patients by specific biological and genetic markers (n = 74) and evaluating the effect of biomarkers on treatment effect (n = 74).

The primary endpoints were improvement on the 17-item Hamilton Depression Rating Scale (HDRS-17) or the Patient Health Questionnaire (PHQ-9).

Patients in all trials were treated with either 7.5 mg or 15 mg of LMF.

Both RCTs were divided into two 30-day phases, with patients assessed every 10 days. Response was defined as at least a 50% reduction in HDRS-17 score during treatment or a final score of 7 or less.
 

‘Salvage pathway’

In the RCTs, patients who received 7.5 mg of LMF did not achieve efficacy superior to placebo, while those receiving 15 mg/day of LMF for 30 days showed significantly greater reduction in HDRS-17 scores (–5.6 vs. –3.0; P = .05, respectively) and higher response rates (32.3% vs. 14.6%; P = .05, respectively).

The 12-month open extension trial showed that among patients who received the 15-mg dose, 61% achieved remission at any point, and 38% achieved recovery. Among initial nonresponders, 60% eventually achieved remission, with no serious adverse events.

“These results indicate that patients who respond well to shorter-term treatment are likely to maintain that response over the subsequent year and shows that those not adequately responding within the first 8 weeks of therapy may benefit from longer-term LMF treatments,” the investigators noted.

In the prospective observational study, the pooled mean change in PHQ-9 was –8.5, with response and remission rates of 67.9% and 45.7%, respectively.

“These outcomes suggest that the results seen in the controlled trial are likely to extend to patients in real-world practice,” the researchers wrote.

The post hoc analyses focusing on the findings of the two RCTs explored the differences in response to LMF, based on biomarker, BMI, and genotype.

Individuals with BMI less than 30 did not have a significant change from baseline with LMF treatment, in contrast to those with BMI of 30 or higher (pooled treatment effect, –4.66;95% CI, –7.22 to –1.98) – a difference the authors call “striking.”

Levels of inflammatory markers (tumor necrosis factor–alpha, interleukin-8, heart-specific C-reactive protein, and leptin) above the median value were associated with significantly greater treatment effect – a finding that remained significant even after adjustment for BMI.

Although BMI and cytokines all showed significant main effects, the “synergy” between them “suggests that these risk factors may interact with each other to influence response to LMF,” the authors wrote.

The mechanism by which LMF augments antidepressant treatment is tied to monoamine synthesis, since LMF promotes the synthesis of key monoamine neurotransmitters associated with MDD (serotonin, norepinephrine, and dopamine), Dr. Maletic explained.

High levels of inflammation (often tied to obesity) cause oxidative stress, which inhibits the synthesis of these neurotransmitters and depletes them more rapidly. LMF provides a “salvage pathway” that may prevent this from happening, thus increasing the antidepressant response of the monoamines, he said.
 

A ‘good addition’

In a comment, David Mischoulon, MD, PhD, Joyce R. Tedlow Professor of Psychiatry at Harvard Medical School and director of the depression clinical and research program at Massachusetts General Hospital, both in Boston, said the paper “does a good job of synthesizing what we know about LMF as an adjunctive treatment in major depression.” 

However, he recommended “caution” when interpreting the findings, since “relatively few” studies were reviewed. 

Dr. Mischoulon, who was not involved with the study, said that a “particularly interesting finding from these studies is individuals who are overweight and/or have elevation in inflammatory activity ... seemed to respond better to the addition of LMF.” This finding is similar to what his research team observed when investigating the potential role of fish oils in treating depression.

“These findings overall are not surprising, in view of the well-established multidirectional relationship between depression, inflammation, and overweight status,” he said. 

LMF “seems like a good addition to the pharmacological armamentarium for depression; and because it is safe and has minimal side effects, it can be added to the treatment regimen of patients who are depressed and not responding adequately to standard antidepressants,” he said.

The B vitamin, L-methylfolate (LMF) can be an effective adjunctive treatment for patients with major depressive disorder (MDD) with an inadequate response to antidepressants, new research suggests.

The investigators analyzed six studies and found support for adjunctive use of LMF with patients with MDD not responding to antidepressant monotherapy. Treatment response was highest in those with obesity and inflammatory biomarkers.

“If clinicians try LMF on their patients with treatment-resistant depression, the treatment is very robust in patients who have high BMI [body mass index] or inflammatory biomarkers, and it’s worth a try even in patients who don’t have these indicators, since it’s safe and well tolerated, with no downside,” study investigator Vladimir Maletic, MD, MS, clinical professor of psychiatry and behavioral science, University of South Carolina, Greenville, said in an interview.

The study was published online in the Journal of Clinical Psychiatry.
 

‘Shortcut’ to the brain

A considerable percentage of patients with MDD fail to achieve an adequate response to treatment, the authors wrote.

Previous research shows benefits of folate (vitamin B9) and other B vitamins in the pathophysiology and treatment of depression.

Folate is available in several forms, including LMF, which differs from dietary folate and synthetic folic acid supplements because it’s a reduced metabolite that readily crosses the blood-brain barrier.

“This is a ‘shortcut’ that gets directly to the brain, especially in those with higher BMI or inflammatory indicators, allowing their antidepressant to work better,” Dr. Maletic said.

LMF is available as a prescription medical food and approved for the clinical dietary management of patients with MDD.

The authors wanted to understand the potential role of LMF in treating patients with MDD with insufficient response to current antidepressant therapy.

They analyzed six studies:

• Two multicenter, randomized, double-blind, placebo-controlled sequential parallel trials for patients with SSRI-resistant MDD (n = 148 and n = 75).
• A 12-month open-label extension trial of the two randomized, controlled trials (n = 68).
• A retrospective cohort study evaluating patients previously prescribed LMF (n = 554).
• Two post hoc exploratory analyses of the second randomized, controlled trial, stratifying patients by specific biological and genetic markers (n = 74) and evaluating the effect of biomarkers on treatment effect (n = 74).

The primary endpoints were improvement on the 17-item Hamilton Depression Rating Scale (HDRS-17) or the Patient Health Questionnaire (PHQ-9).

Patients in all trials were treated with either 7.5 mg or 15 mg of LMF.

Both RCTs were divided into two 30-day phases, with patients assessed every 10 days. Response was defined as at least a 50% reduction in HDRS-17 score during treatment or a final score of 7 or less.
 

‘Salvage pathway’

In the RCTs, patients who received 7.5 mg of LMF did not achieve efficacy superior to placebo, while those receiving 15 mg/day of LMF for 30 days showed significantly greater reduction in HDRS-17 scores (–5.6 vs. –3.0; P = .05, respectively) and higher response rates (32.3% vs. 14.6%; P = .05, respectively).

The 12-month open extension trial showed that among patients who received the 15-mg dose, 61% achieved remission at any point, and 38% achieved recovery. Among initial nonresponders, 60% eventually achieved remission, with no serious adverse events.

“These results indicate that patients who respond well to shorter-term treatment are likely to maintain that response over the subsequent year and shows that those not adequately responding within the first 8 weeks of therapy may benefit from longer-term LMF treatments,” the investigators noted.

In the prospective observational study, the pooled mean change in PHQ-9 was –8.5, with response and remission rates of 67.9% and 45.7%, respectively.

“These outcomes suggest that the results seen in the controlled trial are likely to extend to patients in real-world practice,” the researchers wrote.

Six distinct microribonucleic acids were down-regulated in adults with major depressive disorder (MDD), compared with healthy controls, based on data from 120 individuals.

National University Health System, Singapore

“Given the multifaceted nature of MDD, the multiple small but dynamic genetic alterations in biomolecular pathways, which are modulated by epigenetic modifications, could contribute to a better understanding of the underlying aetiology and pathophysiology of this disorder,” wrote Cyrus Su Hui Ho, MD, of National University Health System, Singapore, and colleagues. However, studies of biomarkers in psychiatry are limited, and the predictive potential of microribonucleic acids (miRNAs) has not been examined, they said.

In a study published in Comprehensive Psychiatry, the researchers identified 60 adults with depression and 60 healthy controls. Depression severity was assessed with the Hamilton Depression Rating Scale. Other demographic and clinical characteristics were similar between the patients and controls; 10 patients were unmedicated.

The researchers used QUIAGEN Ingenuity Pathway Analysis to identify the specific depression-related biological pathways affected by various miRNAs.

A total of six miRNAs (miR-542-3p, miR-181b-3p, miR-190a-5p, miR-33a-3p, miR-3690, and miR-6895-3p) were down-regulated in unmedicated depressed patients, compared with healthy controls.

In a receiver operating characteristic (ROC) analysis, a combination panel with three miRNAs (miR-542-3p, miR-181b-3p, and miR-3690) in whole blood yielded an area under the curve (AUC) of 0.67. This combination correctly classified 66.7% of MDD patients and 63.3% of healthy controls.

The ability of individual miRNAs to differentiate between MDD patients and controls in the current study was limited, the researchers wrote in their discussion. “However, when three miRNAs (miR-542b-3p, miR-181b-3p, and miR-3690) were combined as a panel, the AUC was enhanced to an almost acceptable degree (AUC of 0.67, approaching 0.7) and might have value in complementing clinical diagnoses,” they said.

The study findings were limited by several factors including the small sample size and the use of medications by most MDD patients, which resulted in an especially small number of unmedicated patients, the researchers noted. Other limitations included the use of study population from a single center, and the inability to explain the link between blood and brain miRNA expression, they said.

However, the study is the first clinical trial in Singapore to examine the role of miRNA in depression and to identify miRNAs as potential biomarkers for MDD, they said.

Additional studies are needed to explore miRNA biomarkers for diagnosis, disease prognosis, and treatment response in MDD, they concluded.

The study was supported by the National University Health System Seed Fund. The researchers had no financial conflicts to disclose.

Electroconvulsive therapy (ECT) is the standard treatment for resistant depression, but results of a new randomized, head-to-head trial suggest intravenous ketamine is at least as effective and has fewer side effects.

“The take-home message right now is that if somebody is being referred for ECT, the treating clinician should think of offering ketamine first,” study investigator Amit Anand, MD, professor of psychiatry, Harvard Medical School, Boston, said in an interview.

The study was published online in the New England Journal of Medicine.
 

‘Preferred treatment’

More than one-third of cases of depression are treatment resistant, said Dr. Anand, who is also director of Psychiatry Translational Clinical Trials at Mass General Brigham. He noted that ECT has been the “gold standard for treating severe depression for over 80 years.”

Julia Hiebaum/Alamy

He added that although ECT is very effective and is fast acting, “it requires anesthesia, can be socially stigmatizing, and is associated with memory problems following the treatment.”

An anesthetic agent, ketamine has been shown to have rapid antidepressant effects and does not cause memory loss or carry the stigma associated with ECT, he added. For these reasons, the investigators examined whether it may be a viable alternative to ECT.

To date, no large, head-to-head trials have compared ECT to intravenous ketamine. A recent meta-analysis showed that ECT was superior to ketamine for major depression, but the total number of patients included in the analysis was small, Dr. Anand said.

In addition, most of the participants in that trial were drawn from a single center. Approximately 95 patients were enrolled in each arm of the trial, which included some participants with features of psychosis. “ECT is very effective for depression associated with psychotic features, which may be one reason ECT had a better response in that trial,” said Dr. Anand.

The investigators compared ECT to ketamine in a larger sample that excluded patients with psychosis. They randomly assigned 403 patients at five clinical sites in a 1:1 ratio to receive either ketamine or ECT (n = 200 and 203, respectively; 53% and 49.3% women, respectively; aged 45.6 ± 14.8 and 47.1 ± 14.1 years, respectively).

Patients were required to have had an unsatisfactory response to two or more adequate trials of antidepressant treatment.

Prior to initiation of the assigned treatment, 38 patients withdrew, leaving 195 in the ketamine group and 170 in the ECT group.

Treatment was administered over a 3-week period, during which patients received either ECT three times per week or ketamine (0.5 mg/kg of body weight) twice per week.

The primary outcome was treatment response, defined as a decrease of 50% or more from baseline in the16-item Quick Inventory of Depressive Symptomatology–Self-Report (QIDS-SR-16). Secondary outcomes included scores on memory tests and patient-reported quality of life.

Patients who had a response were followed for 6 months after the initial treatment phase.
 

More research needed

Following the 3-week treatment period, a total of 55.4% patients who received ketamine and 41.2% of patients who underwent ECT responded to treatment, which translates into a difference of 14.2 percentage points (95% confidence interval, 3.9-24.2; P < .001) – a finding that fell within the noninferiority threshold set by the investigators.

ECT was associated with decreased memory recall after the 3 weeks of treatment, with a mean (standard deviation) decrease in the T-score for delayed recall on the Hopkins Verbal Learning Test–Revised of –0.9 (1.1) in the ketamine group vs. –9.7 (1.2) in the ECT group (difference, –1.8 points [–2.8 to –0.8]).

Remission, determined on the basis of QIDS-SR-16 score, occurred in 32% of the ketamine group and in 20% in the ECT group. Similar findings were seen on the Montgomery-Åsberg Depression Rating Scale.

Both groups showed significant improvements in quality of life, with changes of 12.3 and 12.9 points, respectively, on the 16-item Quality of Life Scale.

“ECT was associated with musculoskeletal adverse events, whereas ketamine was associated with dissociation,” the investigators note.

During the 6-month follow-up period, there were differences in relapse rates between the groups (defined as QIDS-SRS-16 score > 11). At 1 month, the rates were 19.0% for those receiving ketamine and 35.4% for those receiving ECT. At 3 months, the rates were 25.0% and 50.9%, respectively; at 6 months, the rates were 34.5% and 56.3%, respectively.

ECT has been shown to be effective for older adults, patients with MDD and psychosis, and in inpatient and research settings. Future studies are needed to determine the comparative effectiveness of ketamine in these populations, the authors note.
 

Not life-changing

In a comment, Dan Iosifescu, MD, professor of psychiatry, NYU Langone Health, New York, called it an “extraordinarily important and clinically relevant study, large, well-designed, and well-conducted.”

Dr. Iosifescu, director of the clinical research division, Nathan Kline Institute, Orangeburg, N.Y., who was not involved with the study, noted that the study wasn’t powered to determine whether one treatment was superior to the other, but rather it assessed noninferiority.

“The main point of this study is that the two treatments are largely equivalent, although numerically, ketamine was slightly associated with more beneficial outcomes and fewer cognitive side effects,” he said.

The findings suggest “that people who have no contraindications and are candidates for both ketamine and ECT – which is the vast majority of people with treatment-resistant depression – should consider getting ketamine first because it is somewhat easier in terms of side effects and logistics and consider ECT afterwards if the ketamine doesn’t work.”

In an accompanying editorial, Robert Freedman, MD, clinical professor, University of Colorado at Denver, Aurora, noted that although “3 weeks of lightened mood is undoubtedly a gift ... the results of this current trial suggests that the 3-week treatment was not life-changing,” since effects had largely worn off by 6 months in both groups.

Longer-term treatment with ketamine “increases the likelihood of both drug dependence and cognitive adverse effects, including dissociation, paranoia, and other psychotic symptoms,” Dr. Freedman said.

He recommends that informed consent documents be used to caution patients and clinicians considering ketamine “that temporary relief may come with longer-term costs.”

The study was supported by a grant from PCORI to Dr. Anand. Dr. Freedman has disclosed no relevant financial relationships. In the past 2 years, Dr. Iosifescu has been a consultant for Axsome, Allergan, Biogen, Clexio, Jazz, Neumora, Relmada, and Sage. He has also received a research grant from Otsuka.

An anesthetic agent, ketamine has been shown to have rapid antidepressant effects and does not cause memory loss or carry the stigma associated with ECT, he added. For these reasons, the investigators examined whether it may be a viable alternative to ECT.

To date, no large, head-to-head trials have compared ECT to intravenous ketamine. A recent meta-analysis showed that ECT was superior to ketamine for major depression, but the total number of patients included in the analysis was small, Dr. Anand said.

In addition, most of the participants in that trial were drawn from a single center. Approximately 95 patients were enrolled in each arm of the trial, which included some participants with features of psychosis. “ECT is very effective for depression associated with psychotic features, which may be one reason ECT had a better response in that trial,” said Dr. Anand.

The investigators compared ECT to ketamine in a larger sample that excluded patients with psychosis. They randomly assigned 403 patients at five clinical sites in a 1:1 ratio to receive either ketamine or ECT (n = 200 and 203, respectively; 53% and 49.3% women, respectively; aged 45.6 ± 14.8 and 47.1 ± 14.1 years, respectively).

Patients were required to have had an unsatisfactory response to two or more adequate trials of antidepressant treatment.

Prior to initiation of the assigned treatment, 38 patients withdrew, leaving 195 in the ketamine group and 170 in the ECT group.

Treatment was administered over a 3-week period, during which patients received either ECT three times per week or ketamine (0.5 mg/kg of body weight) twice per week.

The primary outcome was treatment response, defined as a decrease of 50% or more from baseline in the16-item Quick Inventory of Depressive Symptomatology–Self-Report (QIDS-SR-16). Secondary outcomes included scores on memory tests and patient-reported quality of life.

Patients who had a response were followed for 6 months after the initial treatment phase.
 

More research needed

Following the 3-week treatment period, a total of 55.4% patients who received ketamine and 41.2% of patients who underwent ECT responded to treatment, which translates into a difference of 14.2 percentage points (95% confidence interval, 3.9-24.2; P < .001) – a finding that fell within the noninferiority threshold set by the investigators.

ECT was associated with decreased memory recall after the 3 weeks of treatment, with a mean (standard deviation) decrease in the T-score for delayed recall on the Hopkins Verbal Learning Test–Revised of –0.9 (1.1) in the ketamine group vs. –9.7 (1.2) in the ECT group (difference, –1.8 points [–2.8 to –0.8]).

Remission, determined on the basis of QIDS-SR-16 score, occurred in 32% of the ketamine group and in 20% in the ECT group. Similar findings were seen on the Montgomery-Åsberg Depression Rating Scale.

Both groups showed significant improvements in quality of life, with changes of 12.3 and 12.9 points, respectively, on the 16-item Quality of Life Scale.

“ECT was associated with musculoskeletal adverse events, whereas ketamine was associated with dissociation,” the investigators note.

During the 6-month follow-up period, there were differences in relapse rates between the groups (defined as QIDS-SRS-16 score > 11). At 1 month, the rates were 19.0% for those receiving ketamine and 35.4% for those receiving ECT. At 3 months, the rates were 25.0% and 50.9%, respectively; at 6 months, the rates were 34.5% and 56.3%, respectively.

ECT has been shown to be effective for older adults, patients with MDD and psychosis, and in inpatient and research settings. Future studies are needed to determine the comparative effectiveness of ketamine in these populations, the authors note.
 

Not life-changing

In a comment, Dan Iosifescu, MD, professor of psychiatry, NYU Langone Health, New York, called it an “extraordinarily important and clinically relevant study, large, well-designed, and well-conducted.”

Dr. Iosifescu, director of the clinical research division, Nathan Kline Institute, Orangeburg, N.Y., who was not involved with the study, noted that the study wasn’t powered to determine whether one treatment was superior to the other, but rather it assessed noninferiority.

“The main point of this study is that the two treatments are largely equivalent, although numerically, ketamine was slightly associated with more beneficial outcomes and fewer cognitive side effects,” he said.

The findings suggest “that people who have no contraindications and are candidates for both ketamine and ECT – which is the vast majority of people with treatment-resistant depression – should consider getting ketamine first because it is somewhat easier in terms of side effects and logistics and consider ECT afterwards if the ketamine doesn’t work.”

In an accompanying editorial, Robert Freedman, MD, clinical professor, University of Colorado at Denver, Aurora, noted that although “3 weeks of lightened mood is undoubtedly a gift ... the results of this current trial suggests that the 3-week treatment was not life-changing,” since effects had largely worn off by 6 months in both groups.

Longer-term treatment with ketamine “increases the likelihood of both drug dependence and cognitive adverse effects, including dissociation, paranoia, and other psychotic symptoms,” Dr. Freedman said.

He recommends that informed consent documents be used to caution patients and clinicians considering ketamine “that temporary relief may come with longer-term costs.”

The study was supported by a grant from PCORI to Dr. Anand. Dr. Freedman has disclosed no relevant financial relationships. In the past 2 years, Dr. Iosifescu has been a consultant for Axsome, Allergan, Biogen, Clexio, Jazz, Neumora, Relmada, and Sage. He has also received a research grant from Otsuka.

Electroconvulsive therapy (ECT) is the standard treatment for resistant depression, but results of a new randomized, head-to-head trial suggest intravenous ketamine is at least as effective and has fewer side effects.

“The take-home message right now is that if somebody is being referred for ECT, the treating clinician should think of offering ketamine first,” study investigator Amit Anand, MD, professor of psychiatry, Harvard Medical School, Boston, said in an interview.

The study was published online in the New England Journal of Medicine.
 

‘Preferred treatment’

More than one-third of cases of depression are treatment resistant, said Dr. Anand, who is also director of Psychiatry Translational Clinical Trials at Mass General Brigham. He noted that ECT has been the “gold standard for treating severe depression for over 80 years.”

SAN FRANCISCO – University of California, San Diego, psychiatrist Stephen M. Stahl, MD, PhD, has heard the scary stories about monoamine oxidase inhibitors (MAOIs): Patients supposedly need to be on restrictive diets free of culinary joys like cheese, beer, and wine; they can’t take cold medicines; and they can just forget about anesthesia for dental work or surgery.

Wrong, wrong, and wrong, Dr. Stahl told an audience at the annual meeting of the American Psychiatric Association. While the venerable antidepressants can transform the lives of patients with treatment-resistant depression, he said, MAOIs are plagued by myths that exaggerate their risks.

“These are good options,” he said. “Everybody who prescribes these today, without exception, has seen patients respond after nothing else has – including ECT (electroconvulsive therapy).”

Still, MAOIs, which were first developed in the 1950s, remain little-used in the United States. While an average of six selective serotonin reuptake inhibitors (SSRIs) are prescribed every second in the United States each day, Dr. Stahl said, “there are only a few hundred MAOI prescribers for a few thousand patients.”

The main barrier to the use of the drugs is unfamiliarity, he said. Despite their low profile, they’re appropriate to use after failures of monotherapy with SSRIs/serotonin and norepinephrine reuptake inhibitors (SNRIs) and augmentation with atypical antipsychotics. And they can be used in conjunction with ketamine/esketamine and ECT, which are other options for treatment-resistant depression, he said.

As for the myths about MAOIs, Dr. Stahl said the drugs can indeed interact with tyramine, which is found in foods like cheese, beer, and wine. The interaction can lead to potentially fatal hypertensive crises, Dr. Stahl said, noting that patients should avoid aged cheeses, tap and unpasteurized beer, soy products, and certain other foods. (Patients taking 6 mg transdermal or low-dose oral selegiline can ignore these restrictions.)

But canned beer, certain wines, yogurt, fresh American cheese, mozzarella/pizza chain cheese, cream cheese, and fresh or processed meat/poultry/fish are fine, he said. “Selectively, you can have a pretty high tyramine diet,” he added, although it’s a good idea for patients to have a blood pressure monitor at home.

As for cold medicines, sympathomimetic decongestants and stimulants should be used cautiously with blood pressure monitoring or not at all, he said, but those with codeine or expectorants are OK. Dextromethorphan, a weak serotonin reuptake inhibitor in some cough medicine, should be avoided. However, antihistamines other than chlorpheniramine/brompheniramine are OK to use, he added, and they may be the ideal choice for cold relief.

As for anesthesia, he cautioned that local anesthetics with epinephrine and general anesthesia can disrupt blood pressure. Choose a local anesthetic that does not contain vasoconstrictors, he said, and if surgery with general anesthesia is needed, “you can wash [the MAOI] out if you want” ahead of time.

Benzodiazepines, mivacurium, rapacuronium, morphine, or codeine can be used cautiously, he said, in urgent or elective surgery in a patient on an MAOI.

As for other myths, he said tricyclic antidepressants and related drugs aren’t as troublesome as psychiatrists may assume. Clomipramine and imipramine should be avoided. But other tricyclic antidepressants can be used with caution.

As for painkillers, he said it’s not true that they must be avoided, although MAIOs shouldn’t be taken with meperidine, fentanyl, methadone, tramadol, or tapentadol. Other painkillers, including over-the-counter products like aspirin, NSAIDs, and acetaminophen, should be used with caution, he said. And expert guidance is advised for use of hydromorphone, morphine, oxycodone, or oxymorphone.

In the big picture, he noted, myths are so prevalent “that you have more calls from patients – and other doctors, dentists, and anesthesiologists – about MAO inhibitors then you will ever have about any other drug there.”

Columbia University, New York, psychiatrist Jonathan W. Stewart, MD, also spoke at the presentation on MAIOs at the APA conference. He recommended that colleagues consider the drugs if two or more antidepressants that work in different ways fail to provide relief after 4 weeks at a sufficient dose. Start low with one pill a day, he recommended, and seek full remission – no depressed mood – instead of simply “better.”

Ultimately, he said, “we do patients a disservice” if MAOIs aren’t considered in the appropriate patients.
