In the treatment of depression, clinicians are commonly dealing with a mix of comorbidities that are more complex than just depression, and as such, effective treatment options may likewise require thinking outside of the box – and beyond the definitions of the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, Text Revision).

“The DSM-5 isn’t handed to us on tablets from Mount Sinai,” said Charles B. Nemeroff, MD, PhD, professor and chair in the department of psychiatry and behavioral sciences at the Mulva Clinic for the Neurosciences at the University of Texas at Austin. He spoke at the 21st Annual Psychopharmacology Update presented by Current Psychiatry and the American Academy of Clinical Psychiatrists.

“Our patients don’t fall into these very convenient buckets,” Dr. Nemeroff said. “The problem with depression is patients have very high rates of morbidity and comorbidity.”

The array of potential psychiatric comorbidities that are common in depression is somewhat staggering: As many as 70% of patients also have social anxiety disorder; 67% of patients have obsessive-compulsive disorder (OCD); up to 65% of patients have panic disorder; 48% of patients have posttraumatic stress disorder (PTSD); and 42% have generalized anxiety disorder, Dr. Nemeroff said.

And while the DSM-5 may have all those bases covered, in real world clinical practice, cracking the code of each patient’s unique and often more complicated psychiatric profile – and how to best manage it – can be a challenge. But Dr. Nemeroff said important clues can guide the clinician’s path.

A key starting point is making sure to gauge the severity of the patient’s core depression with one of the validated depression scales – whether it’s the self-reported Beck Depression Inventory, the clinician-rated Hamilton Rating Scale for Depression, the clinician-rated Montgomery Asberg Depression Rating Scale, or the Inventory of Depressive Symptoms, clinicians should pick one and track the score with each visit, Dr. Nemeroff advised.

“It doesn’t matter which tool you prefer – most tend to like the Beck Depression Scale, but the bottom line is that you have to get a measure of severity at every visit,” he said.

Among the most important comorbidities to identify as soon as possible is bipolar disorder, due to the potential worsening of the condition that can occur among those patients if treated with antidepressants, Dr. Nemeroff said.

“The question of whether the patient is bipolar should always be in the back of your mind,” he cautioned. “And if patients have been started on antidepressants, the clues may become evident very quickly.”

The most important indicator that the patient has bipolar disorder “is if they tell you that they were prescribed an antidepressant and it resulted in an increase in what we know to be hypomania – they may describe it as agitation or an inability to sleep,” Dr. Nemeroff said.

Of note, the effect is much more common with SNRIs [serotonin norepinephrine reuptake inhibitors] than SSRIs [selective serotonin reuptake inhibitors], he said.

“The effect is particularly notable with venlafaxine,” he said. “But SNRIs all have the propensity to switch people with depression into hypomania, but only patients who have bipolar disorder.”

“If you give a patient 150 mg of venlafaxine and they switch to developing hypomania, you now have the diagnosis of bipolar disorder, and you can treat them appropriately.”

Other important clues of bipolarity in depressed patients include:

• Family history: Most cases are genetically driven.
• Earlier age of onset (younger than age 25): “If the patient tells you they were depressed prepuberty, you should be thinking about the possibility of bipolar disorder, as it often presents as depression in childhood.”
• Psychotic features: As many as 80% of patients with psychotic depression end up being bipolar, Dr. Nemeroff said.
• Atypical depression: For example, depression with hypersomnia, or having an increased appetite instead of decreased, or a high amount of anxiety.

Remission should be the goal of treatment, and Dr. Nemeroff said that in efforts to accomplish that with the help of medications, psychiatrists may need to think “outside of the box” – or beyond the label.

“Many practitioners become slaves to the PDR [Physicians’ Desk Reference],” he said. “It is only a guide to what the clinical trials show, and not a mandate in terms of dosing.”

“There’s often strong data in the literature that supports going to a higher dose, if necessary, and I have [plenty] of patients, for instance, on 450 or 600 mg of venlafaxine who had not responded to 150 or even 300 mg.”
 

Treatment resistance

When patients continue to fail to respond, regardless of dosing or medication adjustments, Dr. Nemeroff suggested that clinicians should consider the potential important reasons. For instance, in addition to comorbid psychiatric conditions, practitioners should determine if there are medical conditions that they are not aware of.

“Does the patient have an underlying medical condition, such as thyroid dysfunction, early Parkinson’s disease, or even something like cancer?” he said.

There is also the inevitable question of whether the patient is indeed taking the medication. “We know that 30% of our patients do not follow their prescriptions, so of course that’s an important question to ask,” Dr. Nemeroff said.

Finally, while some pharmacogenomic tests are emerging with the suggestion of identifying which patients may or may not respond to certain drugs, Dr. Nemeroff says he’s seen little convincing evidence of their benefits.

“We have a problem in this field in that we don’t have the kinds of markers that they do in oncology, so we’re left with having to generally play trial and error,” he said.

“But when it comes to these pharmacogenomic tests, there’s just no ‘there there’,” he asserted. “From what I’ve seen so far, it’s frankly neuro-mythology.”

Dr. Nemeroff disclosed that he receives grant/research support from the National Institutes of Health and serves as a consultant for and/or on the advisory boards of multiple pharmaceutical companies.

Higher concentrations of serum zinc, alone and in combination with copper, and selenium, were inversely related to an increased risk of sleep disorders in adults, based on data from 3,660 individuals.

Previous research has shown an association between trace metals and sleep and sleep patterns, but data on the impact of serum trace metals on sleep disorders have been limited, wrote Ming-Gang Deng, MD, of Wuhan (China) University and colleagues.

In a study published in the Journal of Affective Disorders, the researchers reviewed data from the National Health and Nutrition Examination Survey (NHANES) 2011-2016 to calculate the odds ratios of sleep disorders and serum zinc (Zn), copper (Cu), and selenium (Se). The study population included adults aged 18 years and older, with an average age of 47.6 years. Approximately half of the participants were men, and the majority was non-Hispanic white. Serum Zn, Cu, and Se were identified at the Environmental Health Sciences Laboratory of the Centers for Disease Control and Prevention National Center for Environmental Health. The lower limits of detection for Zn, Cu, and Se were 2.9 mcg/dL, 2.5 mcg/dL, and 4.5 mcg/L, respectively. Sleep disorders were assessed based on self-reports of discussions with health professionals about sleep disorders, and via the Sleep Disorder Questionnaire.

After adjusting for sociodemographic, behavioral characteristics, and health characteristics, adults in the highest tertiles of serum Zn had a 30% reduced risk of sleep disorders, compared with those in the lowest tertiles of serum Zn (odds ratio, 0.70; P = .035). In measures of trace metals ratios, serum Zn/Cu and Zn/Se also were significantly associated with reduced risk of sleep disorders for individuals in the highest tertiles, compared with those in the lowest tertiles (OR, 0.62 and OR, 0.68, respectively).

However, serum Cu, Se and Cu/Se were not associated with sleep disorder risk.

Sociodemographic factors included age, sex, race, education level, family income level; behavioral characteristics included smoking, alcohol consumption, physical activity, and caffeine intake.

The researchers also used a restricted cubic spline model to examine the dose-response relationships between serum trace metals, serum trace metals ratios, and sleep disorders. In this analysis, higher levels of serum Zn, Zn/Cu, and Zn/Se were related to reduced risk of sleep disorders, while no significant association appeared between serum Cu, Se, or Cu/Se and sleep disorders risk.

The findings showing a lack of association between Se and sleep disorders were not consistent with previous studies, the researchers wrote in their discussion. Previous research has shown that a higher Se was less likely to be associated with trouble falling asleep, and has shown a potential treatment effect of Se on obstructive sleep apnea, they said.

“Although serum Cu and Se levels were not correlated to sleep disorders in our study, the Zn/Cu and Zn/Se may provide some novel insights,” they wrote. For example, Zn/Cu has been used as a predictor of several clinical complications related to an increased risk of sleep disorders including cardiovascular disease, cancer, and major depressive disorder, they noted.

The findings were limited by several factors including the cross-sectional design, use of self-reports, and the inability to examine relationships between trace metals and specific sleep disorder symptoms, such as restless legs syndrome, insomnia, and obstructive sleep apnea, the researchers noted.

However, the results were strengthened by the large national sample, and support data from previous studies, they said.

“The inverse associations of serum Zn, and Zn/Cu, Zn/Se with sleep disorders enlightened us that increasing Zn intake may be an excellent approach to prevent sleep disorders due to its benefits from these three aspects,” they concluded.

The study received no outside funding. The researchers had no financial conflicts to disclose.

A year ago in December, mapping specialist Whitney Tyshynski, 35, was working out 5 days a week with a personal trainer near her home in Alberta, Canada, doing 5k trail runs, lifting heavy weights, and feeling good. Then, in January she got COVID-19. The symptoms never went away.
 

Nowadays, Ms. Tyshynski needs a walker to retrieve her mail, a half-block trip she can’t make without fear of fainting. Because she gets dizzy when she drives, she rarely goes anywhere in her car. Going for a dog walk with a friend means sitting in a car and watching the friend and the dogs in an open field. And since fainting at Costco during the summer, she’s afraid to shop by herself.

Because she lives alone and her closest relatives are an hour and a half away, Ms. Tyshynski is dependent on friends. But she’s reluctant to lean on them because they already have trouble understanding how debilitating her lingering symptoms can be.

“I’ve had people pretty much insinuate that I’m lazy,” she says.

There’s no question that COVID-19 cut people off from one another. But for those like Ms. Tyshynski who have long COVID, that disconnect has never ended. It’s not just that symptoms including extreme fatigue and brain fog make it difficult to socialize; it’s that people who had COVID-19 and recovered are often skeptical that the condition is real.

At worst, as Ms. Tyshynski has discovered, people don’t take it seriously and accuse those who have it of exaggerating their health woes. In that way, long COVID can be as isolating as the original illness.

“Isolation in long COVID comes in various forms and it’s not primarily just that physical isolation,” says Yochai Re’em, MD, a psychiatrist in private practice in New York who has experienced long COVID and blogs about the condition for Psychology Today. “A different yet equally challenging type of isolation is the emotional isolation, where you need more emotional support, connection with other people who can appreciate what it is you are going through without putting their own needs and desires onto you – and that can be hard to find.”

It’s hard to find in part because of what Dr. Re’em sees as a collective belief that anyone who feels bad should be able to get better by exercising, researching, or going to a doctor.

“Society thinks you need to take some kind of action and usually that’s a physical action,” he says. “And that attitude is tremendously problematic in this illness because of the postexertional malaise that people experience: When people exert themselves, their symptoms get worse. And so the action that people take can’t be that traditional action that we’re used to taking in our society.”

Long COVID patients often have their feelings invalidated not just by friends, loved ones, and extended family, but by health care providers. That can heighten feelings of isolation, particularly for people who live alone, says Jordan Anderson, DO, a neuropsychiatrist and assistant professor of psychiatry at Oregon Health & Science University in Portland.

The first patients Dr. Anderson saw as part of OHSU’s long COVID program contracted the virus in February 2020. Because the program addresses both the physical and mental health components of the condition, Dr. Anderson has seen a lot of people whose emotional challenges are similar to those Ms. Tyshynski faces.

“I think there’s a lack of understanding that leads to people just not necessarily taking it seriously,” he says. “Plus, the symptoms of long COVID do wax and wane. They’re not static. So people can be feeling pretty good one day and be feeling terrible the next. There’s some predictability to it, but it’s not absolutely predictable. It can be difficult for people to understand.”

Both Dr. Anderson and Dr. Re’em stress that long COVID patients need to prioritize their own energy regardless of what they’re being told by those who don’t understand the illness. Dr. Anderson offers to speak to his patients’ spouses to educate them about the realities of the condition because, he says, “any kind of lack of awareness or understanding in a family member or close support could potentially isolate the person struggling with long COVID.”

Depending on how open-minded and motivated a friend or relative is, they might develop more empathy with time and education, Dr. Re’em says. But for others, dealing with a confusing, unfamiliar chronic illness can be overwhelming and provoke anxiety.

“The hopelessness is too much for them to sit with, so instead they say things like ‘just push through it,’ or ‘just do X, Y, and Z,’ because psychologically it’s too much for them to take on that burden,” he says.

The good news is that there are plenty of web-based support groups for people with long COVID, including Body Politic (which Dr. Re’em is affiliated with), Survivor Corps, and on Facebook. “The patient community with this illness is tremendous, absolutely tremendous,” Dr. Re’em says. “Those people can be found and they can support each other.”

Some long COVID clinics run groups, as do individual practitioners such as Dr. Re’em, although those can be challenging to join. For instance, Dr. Re’em’s are only for New York state residents.

The key to finding a group is to be patient, because finding the right one takes time and energy.

“There are support groups that exist, but they are not as prevalent as I would like them to be,” Dr. Anderson says.

OHSU had an educational support group run by a social worker affiliated with the long COVID hub, but when the social worker left the program, the program was put on hold.

There’s a psychotherapy group operating out of the psychiatry department, but the patients are recruited exclusively from Dr. Anderson’s clinic and access is limited.

“The services exist, but I think that generally they’re sparse and pretty geographically dependent,” Dr. Anderson says. “I think you’d probably more likely be able to find something like this in a city or an area that has an academic institution or a place with a lot of resources rather than out in a rural community.”

Ms. Tyshynski opted not to join a group for fear it would increase the depression and anxiety that she had even before developing long COVID. When she and her family joined a cancer support group when her father was ill, she found it more depressing than helpful. Where she has found support is from the cofounder of the animal rescue society where she volunteers, a woman who has had long COVID for more than 2 years and has been a source of comfort and advice.

It’s one of the rare reminders Ms. Tyshynski has that even though she may live alone, she’s not completely alone. “Other people are going through this, too,” she says. “It helps to remember that.”

A year ago in December, mapping specialist Whitney Tyshynski, 35, was working out 5 days a week with a personal trainer near her home in Alberta, Canada, doing 5k trail runs, lifting heavy weights, and feeling good. Then, in January she got COVID-19. The symptoms never went away.
 

Nowadays, Ms. Tyshynski needs a walker to retrieve her mail, a half-block trip she can’t make without fear of fainting. Because she gets dizzy when she drives, she rarely goes anywhere in her car. Going for a dog walk with a friend means sitting in a car and watching the friend and the dogs in an open field. And since fainting at Costco during the summer, she’s afraid to shop by herself.

Because she lives alone and her closest relatives are an hour and a half away, Ms. Tyshynski is dependent on friends. But she’s reluctant to lean on them because they already have trouble understanding how debilitating her lingering symptoms can be.

“I’ve had people pretty much insinuate that I’m lazy,” she says.

There’s no question that COVID-19 cut people off from one another. But for those like Ms. Tyshynski who have long COVID, that disconnect has never ended. It’s not just that symptoms including extreme fatigue and brain fog make it difficult to socialize; it’s that people who had COVID-19 and recovered are often skeptical that the condition is real.

At worst, as Ms. Tyshynski has discovered, people don’t take it seriously and accuse those who have it of exaggerating their health woes. In that way, long COVID can be as isolating as the original illness.

“Isolation in long COVID comes in various forms and it’s not primarily just that physical isolation,” says Yochai Re’em, MD, a psychiatrist in private practice in New York who has experienced long COVID and blogs about the condition for Psychology Today. “A different yet equally challenging type of isolation is the emotional isolation, where you need more emotional support, connection with other people who can appreciate what it is you are going through without putting their own needs and desires onto you – and that can be hard to find.”

It’s hard to find in part because of what Dr. Re’em sees as a collective belief that anyone who feels bad should be able to get better by exercising, researching, or going to a doctor.

“Society thinks you need to take some kind of action and usually that’s a physical action,” he says. “And that attitude is tremendously problematic in this illness because of the postexertional malaise that people experience: When people exert themselves, their symptoms get worse. And so the action that people take can’t be that traditional action that we’re used to taking in our society.”

Long COVID patients often have their feelings invalidated not just by friends, loved ones, and extended family, but by health care providers. That can heighten feelings of isolation, particularly for people who live alone, says Jordan Anderson, DO, a neuropsychiatrist and assistant professor of psychiatry at Oregon Health & Science University in Portland.

The first patients Dr. Anderson saw as part of OHSU’s long COVID program contracted the virus in February 2020. Because the program addresses both the physical and mental health components of the condition, Dr. Anderson has seen a lot of people whose emotional challenges are similar to those Ms. Tyshynski faces.

“I think there’s a lack of understanding that leads to people just not necessarily taking it seriously,” he says. “Plus, the symptoms of long COVID do wax and wane. They’re not static. So people can be feeling pretty good one day and be feeling terrible the next. There’s some predictability to it, but it’s not absolutely predictable. It can be difficult for people to understand.”

Both Dr. Anderson and Dr. Re’em stress that long COVID patients need to prioritize their own energy regardless of what they’re being told by those who don’t understand the illness. Dr. Anderson offers to speak to his patients’ spouses to educate them about the realities of the condition because, he says, “any kind of lack of awareness or understanding in a family member or close support could potentially isolate the person struggling with long COVID.”

Depending on how open-minded and motivated a friend or relative is, they might develop more empathy with time and education, Dr. Re’em says. But for others, dealing with a confusing, unfamiliar chronic illness can be overwhelming and provoke anxiety.

“The hopelessness is too much for them to sit with, so instead they say things like ‘just push through it,’ or ‘just do X, Y, and Z,’ because psychologically it’s too much for them to take on that burden,” he says.

The good news is that there are plenty of web-based support groups for people with long COVID, including Body Politic (which Dr. Re’em is affiliated with), Survivor Corps, and on Facebook. “The patient community with this illness is tremendous, absolutely tremendous,” Dr. Re’em says. “Those people can be found and they can support each other.”

Some long COVID clinics run groups, as do individual practitioners such as Dr. Re’em, although those can be challenging to join. For instance, Dr. Re’em’s are only for New York state residents.

The key to finding a group is to be patient, because finding the right one takes time and energy.

“There are support groups that exist, but they are not as prevalent as I would like them to be,” Dr. Anderson says.

OHSU had an educational support group run by a social worker affiliated with the long COVID hub, but when the social worker left the program, the program was put on hold.

There’s a psychotherapy group operating out of the psychiatry department, but the patients are recruited exclusively from Dr. Anderson’s clinic and access is limited.

“The services exist, but I think that generally they’re sparse and pretty geographically dependent,” Dr. Anderson says. “I think you’d probably more likely be able to find something like this in a city or an area that has an academic institution or a place with a lot of resources rather than out in a rural community.”

Ms. Tyshynski opted not to join a group for fear it would increase the depression and anxiety that she had even before developing long COVID. When she and her family joined a cancer support group when her father was ill, she found it more depressing than helpful. Where she has found support is from the cofounder of the animal rescue society where she volunteers, a woman who has had long COVID for more than 2 years and has been a source of comfort and advice.

The U.S. Food and Drug Administration has approved the medication lenacapavir (Sunlenca) for adults living with multidrug resistant HIV-1 infection. After the initial doses are completed – given both orally and via subcutaneous injection – the drug is administered by injection every 6 months.
 

“Following today’s decision from the FDA, lenacapavir helps to fill a critical unmet need for people with complex prior treatment histories and offers physicians a long-awaited twice-yearly option for these patients who otherwise have limited therapy choices,” said site principal investigator Sorana Segal-Maurer, MD, a professor of clinical medicine at Weill Cornell Medicine, New York, in a statement.

HIV drug regimens generally consist of two or three HIV medicines combined in a daily pill. In 2021, the FDA approved the first injectable complete drug regimen for HIV-1, Cabenuva, which can be administered monthly or every other month. Lenacapavir is administered only twice annually, but it is also combined with other antiretrovirals. The injections and oral tablets of lenacapavir are estimated to cost $42,250 in the first year of treatment and then $39,000 annually in the subsequent years, Reuters reported.

Lenacapavir is the first of a new class of drug called capsid inhibitors to be FDA-approved for treating HIV-1. The drug blocks the HIV-1 virus’s protein shell and interferes with essential steps of the virus’s evolution. The approval, announced today, was based on a multicenter clinical trial of 72 patients with multidrug resistant HIV-1 infection. After a year of the medication, 30 (83%) of the 36 patients randomly assigned to take lenacapavir, in combination with other HIV medications, had undetectable viral loads.

“Today’s approval ushers in a new class of antiretroviral drugs that may help patients with HIV who have run out of treatment options,” said Debra Birnkrant, MD, director of the division of antivirals in the FDA’s Center for Drug Evaluation and Research, in a press release. “The availability of new classes of antiretroviral medications may possibly help these patients live longer, healthier lives.”

NEW ORLEANS – Addressing an audience of hematologists, an immunologist and a thrombosis specialist presented insights on two hot COVID-19 topics: strategies the virus uses to breach the immune system and the diagnosis and treatment of vaccine-related blood clots.

In a presidential symposium at the annual meeting of the American Society of Hematology, La Jolla Institute of Immunology scientist Shane Crotty, PhD, explained that COVID-19 has a “superpower” that allows it to be “extraordinarily stealthy.”

The virus, he said, can sneak past the body’s innate immune system, which normally responds to viral invaders within minutes to hours. “This is why you have people with high viral loads who are presymptomatic. Their innate immune system hasn’t even recognized that these people are infected.”

The adaptive immune system kicks in later. As Dr. Crotty noted, adaptive immunity is composed of three branches: B cells (the source of antibodies), CD4 “helper” T cells, and CD8 “killer” T cells. In the first year of COVID-19, his team tracked 188 subjects post infection in what he said was the largest study of its kind ever for any viral infection.

“In 8 months, 95% of people who had been infected still had measurable immune memory. In fact, most of them had multiple different compartments of immune memory still detectable, and it was likely that these individuals would still have that memory years into the future. Based on that, we made the prediction that most people who have had COVID-19 would likely be protected from reinfection – at least by severe infections – for 3 years into the future. That prediction has widely held up even in the presence of variants which weren’t around at the time.”

How do vaccines fit into the immunity picture? Dr. Crotty’s lab has tracked subjects who received 4 vaccines – Moderna, Pfizer/BioNTech, Janssen/Johnson & Johnson, and Novavax. Researchers found that the mRNA vaccines, Moderna and Pfizer/BioNTech, “are fantastic at eliciting neutralizing antibodies quickly, but then they drop off rapidly at two doses and actually continue to drop for 10 months.”

Still, he said, “when we take a look at 6 months, actually the vaccines are doing pretty incredibly well. If we compare them to an average infected individual, the mRNA vaccines all have higher neutralizing antibody titers.”

What’s happening? According to Dr. Crotty, B cells are “making guesses about what other variants might look like.” But he said research suggests that an important component of this process – germinal centers – aren’t made in some vaccinated people who are immunocompromised. (Germinal centers have been described as “microbial boot camps” for B cells.)

The good news, Dr. Crotty noted, is that a greater understanding of how COVID-19 penetrates various layers of adaptive immune defenses will lead to better ways to protect the immunocompromised. “If you think about immunity in this layered defense way, there are various ways that it could be enhanced for individuals in different categories,” he said.

Hematologist Beverley J. Hunt, MD, OBE, of St. Thomas’ Hospital/King’s Healthcare Partners in London, spoke at the ASH presidential symposium about blood clots and COVID-19. As she noted, concern arose about vaccine-related blood clots. A British team “managed quickly to come up with a diagnostic criteria,” she said. “We looked at nearly 300 patients and essentially came up with a scoring system.”

The diagnostic criteria was based on an analysis of definite or probable cases of vaccine-induced immune thrombocytopenia and thrombosis (VITT) – all related to the AstraZeneca vaccine. The criteria appeared in a 2021 study in the New England Journal of Medicine.

The report’s data didn’t allow it to compare the efficacy of anticoagulants. However, Dr. Hunt noted that clinicians turned to plasma exchange in patients with low platelet counts and extensive thrombosis. The report stated “survival after plasma exchange was 90%, considerably better than would be predicted given the baseline characteristics.”

“Now we’re following up,” Dr. Hunt said. One question to answer: Is long-term anticoagulation helpful? “We have many patients,” she said, “who are taking an anti-platelet factor out of habit.”

This patient's clinical presentation and endoscopy findings are consistent with a diagnosis of recurrent MCL presenting as a colonic mass.

MCL is an aggressive type of non-Hodgkin lymphoma that accounts for approximately 5%-7% of all lymphomas. Nearly 80% of patients have extranodal involvement at initial presentation, occurring in sites such as the bone marrow, spleen, Waldeyer ring, and the gastrointestinal (GI) tract. Secondary GI involvement in MCL (involving nodal and/or other extranodal tissue) is common and may be detected at diagnosis and/or relapse. In several retrospective studies, the prevalence of secondary GI involvement in MCL ranged from 15% to 30%. However, in later studies, routine endoscopies in patients with untreated MCL showed GI involvement in up to 90% of patients, despite most patients not reporting GI symptoms.

The colon is the most commonly involved GI site; however, both the upper and lower GI tract from the stomach to the colon can be involved. Lymphomatous polyposis is the most common endoscopic presentation of MCL, but polyp, mass, or even normal-appearing mucosa may also be seen. 

New and emerging treatment options are helping to improve survival in patients with relapsed/refractory MCL. According to National Comprehensive Cancer Network guidelines, the preferred second-line and subsequent regimens are:

•    Bruton tyrosine kinase (BTK) inhibitors:

o    Acalabrutinib
o    Ibrutinib ± rituximab
o    Zanubrutinib

•    Lenalidomide + rituximab (if BTK inhibitor is contraindicated)

Other regimens that may be useful in certain circumstances are:

•    Bendamustine + rituximab (if not previously given)
•    Bendamustine + rituximab + cytarabine (RBAC500) (if not previously given)
•    Bortezomib ± rituximab
•    RDHA (rituximab, dexamethasone, cytarabine) + platinum (carboplatin, cisplatin, or oxaliplatin) (if not previously given)
•    GemOx (gemcitabine, oxaliplatin) + rituximab

This patient's clinical presentation and endoscopy findings are consistent with a diagnosis of recurrent MCL presenting as a colonic mass.

MCL is an aggressive type of non-Hodgkin lymphoma that accounts for approximately 5%-7% of all lymphomas. Nearly 80% of patients have extranodal involvement at initial presentation, occurring in sites such as the bone marrow, spleen, Waldeyer ring, and the gastrointestinal (GI) tract. Secondary GI involvement in MCL (involving nodal and/or other extranodal tissue) is common and may be detected at diagnosis and/or relapse. In several retrospective studies, the prevalence of secondary GI involvement in MCL ranged from 15% to 30%. However, in later studies, routine endoscopies in patients with untreated MCL showed GI involvement in up to 90% of patients, despite most patients not reporting GI symptoms.

The colon is the most commonly involved GI site; however, both the upper and lower GI tract from the stomach to the colon can be involved. Lymphomatous polyposis is the most common endoscopic presentation of MCL, but polyp, mass, or even normal-appearing mucosa may also be seen. 

New and emerging treatment options are helping to improve survival in patients with relapsed/refractory MCL. According to National Comprehensive Cancer Network guidelines, the preferred second-line and subsequent regimens are:

•    Bruton tyrosine kinase (BTK) inhibitors:

o    Acalabrutinib
o    Ibrutinib ± rituximab
o    Zanubrutinib

•    Lenalidomide + rituximab (if BTK inhibitor is contraindicated)

Other regimens that may be useful in certain circumstances are:

•    Bendamustine + rituximab (if not previously given)
•    Bendamustine + rituximab + cytarabine (RBAC500) (if not previously given)
•    Bortezomib ± rituximab

An updated Cochrane Review on infant skincare interventions for preventing atopic dermatitis (AD) and food allergy has reaffirmed previous study findings indicating a lack of benefit, and strengthened the suggestion of harm associated with early use of emollients.

The document, published in November 2022, updates a February 2021 version, said Robert Boyle, MD, PhD, senior author of the Cochrane Review and a pediatric allergist at Imperial College London. “The differences were slight,” he told this news organization. “Mainly, we had a little more data about food allergy outcomes, which slightly strengthened the concern about a possible increase in food allergy with emollients; and we had some new genetic information, which allowed us to add some further interaction analyses and confirm that chromosome 11 intergenic variant rs2212434 doesn’t seem to impact the effect – or lack of effect – of emollient on eczema development.”

The updated Cochrane Review concludes that, “based on low‐ to moderate-certainty evidence, skin care interventions such as emollients during the first year of life in healthy infants are probably not effective for preventing eczema; may increase risk of food allergy; and probably increase risk of skin infection.”

The latest publication should strengthen clinicians’ confidence in not recommending emollient use for preventing AD in at-risk infants – however, that message is being diluted by a stream of contradictory conclusions from poor-quality systematic reviews, say Dr. Boyle and two coauthors. “It’s a systematic problem of people churning out endless systematic reviews without much rigor,” explained the lead author Maeve Kelleher, MD, from Children’s Health Ireland, Crumlin. There have been “misleading systematic reviews published, often in high-ranking journals,” agreed Dr. Boyle.

“I have been an advocate of systematic reviews for the last 20 years, but they have gone completely out of control,” added Hywel Williams, MD, PhD, another of the Cochrane Review coauthors, who is professor of dermato-epidemiology and codirector of the Centre of Evidence Based Dermatology, at Nottingham (England) University Hospitals NHS Trust. In an editorial, published last year, Dr. Williams even posed the question: “Are Dermatology Systematic Reviews Spinning Out of Control?” in which he blamed “the misrepresentation of study results” – which he calls “the sin of spin” – for degrading the quality of science in dermatology.

“The field has become a ‘sausage machine’ industry that undermines the value of systematic reviews in providing a summary of the best evidence to inform patient care,” he wrote. “Fewer systematic reviews are needed in dermatology,” but “better ones” are needed, he continued, calling for all systematic reviews to be registered prospectively, and reported according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines.

Earlier this year, in a letter to the editor, Dr. Kelleher, Dr. Boyle, Dr. Williams, and several others outlined their concerns after a systemic review and meta-analysis was published, “which came to very different conclusions” than their Cochrane Review.

“It is quite common to see non-Cochrane reviews published in leading specialty journals, which interpret data in a more positive light than Cochrane reviews, which have assessed a similar dataset/topic,” Dr. Boyle said in the interview.

Such concerns also apply to the publication of another systematic review that was recently published. “Overall, early application of emollients is an effective strategy for preventing AD development in high-risk infants,” reported senior author Xiaojing Kang, MD, PhD, from People’s Hospital of Xinjiang Uygur Autonomous Region, Urumchi, China, and coauthors, who could not be reached for comment. In their discussion, the authors cite several criticisms of the Cochrane Review: that it included two meeting abstracts and two “ineligible” studies; did not do subgroup analysis of high-risk infants; did not look at different types of emollients; and did not examine the risk of food sensitization.

“A Cochrane Review can be quite a large and complex document to negotiate for those who are not very familiar with Cochrane’s methodology,” said Dr. Boyle. He dismissed the criticism, saying “we did do subgroup analysis of high risk infants, we did look at different types of emollient, and we did look at food sensitization and food allergy risk. We only included eligible studies. … Certainly we would include abstracts of trials, which are not reported in any other form, in order to capture as complete a picture.”

Ultimately, Dr. Boyle said, the discrepancy in conclusions between such systematic reviews and the Cochrane Review relates to quality of methodology. “Our Cochrane review was an individual participant data (IPD) meta-analysis, meaning that authors of the main trials in this area shared their original datasets with us,” he said in the interview. “This is the ‘gold standard’ in systematic reviews, and allowed us to check data/ query inconsistencies and to apply a single-analysis methodology across all studies. It also allowed us to undertake some analyses, which are just not possible in aggregate data analysis based on published work without IPD.”

The most recently published systematic review had no registered protocol, “so, there is no transparency about the methods used,” he noted. “It is free and simple to register a protocol – multiple websites such as PROSPERO, open science framework, and zenodo allow this,” he said “In the journal I edit, we use availability of a registered protocol as a marker of quality. We find that systematic reviews with no registered protocol are almost universally poor quality.”

Dr. Williams is a founding member and coordinating editor of the Cochrane Skin Group 1998 to 2017. Dr. Boyle was paid by Cochrane for senior editor work, until recently, and had no other relevant disclosures. Dr. Kelleher had no relevant disclosures.

Lithium carbonate is a mood stabilizer that is effective in the treatment of bipolar disorder, particularly in controlling mania.¹ Lithium can reduce the risk of suicide,² treat aggression and self-mutilating behavior,³ and prevent steroid-induced psychosis.⁴ It also can raise the white cell count in patients with clozapine-induced leukopenia.⁵

To prevent or lower the risk of relapse, the therapeutic plasma level of lithium should be regularly monitored to ensure an optimal concentration in the CNS. The highest tolerable level of lithium in the plasma is 0.6 to 0.8 mmol/L, with the optimal level ranging up to 1.2 mmol/L.⁶ Regular monitoring of renal function is also required to prevent renal toxicity, particularly if the plasma level exceeds 0.8 mmol/L.⁷ Because of lithium’s relatively narrow therapeutic index, its interaction with other medications, such as angiotensin-converting enzyme inhibitors, diuretics, nonsteroidal anti-inflammatory drugs (NSAIDs), and carbamazepine, can also precipitate lithium toxicity.⁸ We describe a lesson learned from a case of lithium toxicity in an otherwise healthy patient with bipolar disorder.

Case report

An otherwise healthy 39-year-old woman diagnosed with bipolar type I disorder was receiving valproate sodium 600 mg/d and olanzapine 10 mg/d. Despite improvement in her mood, she gained 11.6 kg following 6 months of treatment. As a result, olanzapine was switched to aripiprazole 10 mg/d that was later increased to 15 mg/d, and sodium valproate was gradually optimized up to 1,000 mg/d. She later complained of hair thinning and hair loss so she self-adjusted her medication dosages, which resulted in frequent relapses. Her mood stabilizer was changed from sodium valproate to lithium 600 mg/d.

Unfortunately, after taking lithium for 15 days, she returned to us with fever associated with reduced oral intake, poor sleep, bilateral upper limb rigidity, and bilateral hand tremor. She also complained of extreme thirst and fatigue but no vomiting or diarrhea. She had difficulty falling asleep and slept for only 1 to 2 hours a day. Her symptoms worsened when a general practitioner prescribed NSAIDs for her fever and body ache. Her tremors were later generalized, which made it difficult for her to take her oral medications and disturbed her speech and movement.

On evaluation, our patient appeared comfortable and not agitated. She was orientated to time, place, and person. Her blood pressure was 139/89 mmHg, heart rate was 104 bpm, and she was afebrile. She was dehydrated with minimal urine output. She had coarse tremor in her upper and lower limbs, which were hypertonic but did not display hyperreflexia or clonus. There was no nystagmus or ataxia. A mental state examination showed no signs of manic, hypomanic, or depressive symptoms. She had slurred speech, and her affect was restricted.

Blood investigation revealed a suprathreshold lithium level of 1.70 mmol/L (normal: 0.8 to 1.2 mmol/L). Biochemical parameters showed evidence of acute kidney injury (urea: 6.1 mmol/L; creatinine: 0.140 mmol/L), with no electrolyte imbalance. There was no evidence of hypothyroidism (thyroid-stimulating hormone: 14.9 mIU/L; free thyroxine: 9.9 pmol/L), hyperparathyroidism, or hypercalcemia. Autoimmune markers were positive for antinuclear antibody (titre 1:320) and anti-double stranded DNA (76.8 IU/mL). Apart from hair loss, she denied other symptoms associated with autoimmune disease, such as joint pain, butterfly rash, or persistent fatigue. Other routine blood investigations were within normal limits. Her urine protein throughout admission had shown persistent proteinuria ranging from 3+ to 4+. Electrocardiogram (ECG) showed normal sinus rhythm with no T wave inversion or QT prolongation.

Continue to: A detailed family history...

A detailed family history later confirmed a strong family history of renal disease: her mother had lupus nephritis with nephrotic syndrome, and her brother had died from complications of a rapidly progressive glomerulonephritis. Her renal function prior to lithium initiation was within normal limits (urea: 4.0 mmol/L; serum creatinine: 78 µmol/L).

In the ward, lithium and aripiprazole were discontinued, and she was hydrated. Combined care with the psychiatric and medical teams was established early to safeguard against potential CNS deterioration. She showed marked clinical improvement by Day 3, with the resolution of coarse tremor and rigidity as well as normalization of blood parameters. Her lithium level returned to a therapeutic level by Day 4 after lithium discontinuation, and her renal profile gradually normalized. She was restarted on aripiprazole 10 mg/d for her bipolar illness and responded well. She was discharged on Day 5 with a referral to the nephrology team for further intervention.

Lessons learned

This case highlights the issue of lithium safety in susceptible individuals and the importance of risk stratification in this group of patients. Lithium is an effective treatment for bipolar I disorder and has also been used as adjunctive treatment for major depressive disorder, schizoaffective disorder, treatment-resistant schizophrenia, anorexia nervosa and bulimia nervosa, and the control of chronic aggression.⁹ Lithium is completely absorbed by the gastrointestinal tract following ingestion, is not metabolized, and is eliminated almost entirely by the kidneys (though trace amounts may be found in feces and perspiration).

In our case, a detailed family history of renal disease was not adequately explored until our patient presented with signs suggestive of lithium toxicity. Our patient had been prescribed lithium 600 mg/d as a maintenance therapy. Upon starting lithium, her baseline biochemical parameters were within normal limits, and renal issues were not suspected. The hair thinning and hair loss she experienced could have been an adverse effect of valproate sodium or a manifestation of an underlying autoimmune disease. Coupled with the use of NSAIDs that could have precipitated acute kidney injury, her poor oral intake and dehydration during the acute illness further impaired lithium excretion, leading to a suprathreshold plasma level despite a low dose of lithium. Therefore, before prescribing lithium, a thorough medical and family history is needed, supplemented by an evaluation of renal function, serum electrolytes, and thyroid function to determine the starting dosage of lithium. Routine vital sign assessment and ECG should also be conducted, and concurrent medications and pregnancy status should be confirmed before prescribing lithium. Regular lithium level monitoring is essential.

Measuring a patient’s estimated glomerular filtration rate (eGFR) is recommended to validate renal status¹⁰ and classify and stage kidney disease.¹¹ Combining eGFR with blood urea nitrogen, serum creatinine, and urine microscopic analysis further improves the prediction of renal disease in early stages. We recommend considering a blood test for autoimmune markers in patients with clinical suspicion of autoimmune disease, in the presence of suggestive signs and symptoms, and/or in patients with a positive family history (Table).

Before starting lithium, in addition to conducting a detailed clinical evaluation, information about symptoms and the risk of lithium toxicity should be discussed with patients.¹² Our case serves as a timely reminder that the lack of suggestive biochemical parameters of renal disease should not rule out an underlying renal disease, and a strong family history of renal disease should warrant suspicion of a possible autoimmune origin.

We suggest that future studies evaluate the risks of lithium toxicity in susceptible groups of patients, such as those with family history of renal disease.

Combined care with the psychiatric and medical teams was established early to safeguard against potential CNS deterioration. She showed marked clinical improvement by Day 3, with the resolution of coarse tremor and rigidity as well as normalization of blood parameters. Her lithium level returned to a therapeutic level by Day 4 after lithium discontinuation, and her renal profile gradually normalized. She was restarted on aripiprazole 10 mg/d for her bipolar illness and responded well. She was discharged on Day 5 with a referral to the nephrology team for further intervention.

Lessons learned

This case highlights the issue of lithium safety in susceptible individuals and the importance of risk stratification in this group of patients. Lithium is an effective treatment for bipolar I disorder and has also been used as adjunctive treatment for major depressive disorder, schizoaffective disorder, treatment-resistant schizophrenia, anorexia nervosa and bulimia nervosa, and the control of chronic aggression.⁹ Lithium is completely absorbed by the gastrointestinal tract following ingestion, is not metabolized, and is eliminated almost entirely by the kidneys (though trace amounts may be found in feces and perspiration).

In our case, a detailed family history of renal disease was not adequately explored until our patient presented with signs suggestive of lithium toxicity. Our patient had been prescribed lithium 600 mg/d as a maintenance therapy. Upon starting lithium, her baseline biochemical parameters were within normal limits, and renal issues were not suspected. The hair thinning and hair loss she experienced could have been an adverse effect of valproate sodium or a manifestation of an underlying autoimmune disease. Coupled with the use of NSAIDs that could have precipitated acute kidney injury, her poor oral intake and dehydration during the acute illness further impaired lithium excretion, leading to a suprathreshold plasma level despite a low dose of lithium. Therefore, before prescribing lithium, a thorough medical and family history is needed, supplemented by an evaluation of renal function, serum electrolytes, and thyroid function to determine the starting dosage of lithium. Routine vital sign assessment and ECG should also be conducted, and concurrent medications and pregnancy status should be confirmed before prescribing lithium. Regular lithium level monitoring is essential.

Measuring a patient’s estimated glomerular filtration rate (eGFR) is recommended to validate renal status¹⁰ and classify and stage kidney disease.¹¹ Combining eGFR with blood urea nitrogen, serum creatinine, and urine microscopic analysis further improves the prediction of renal disease in early stages. We recommend considering a blood test for autoimmune markers in patients with clinical suspicion of autoimmune disease, in the presence of suggestive signs and symptoms, and/or in patients with a positive family history (Table).

Before starting lithium, in addition to conducting a detailed clinical evaluation, information about symptoms and the risk of lithium toxicity should be discussed with patients.¹² Our case serves as a timely reminder that the lack of suggestive biochemical parameters of renal disease should not rule out an underlying renal disease, and a strong family history of renal disease should warrant suspicion of a possible autoimmune origin.

We suggest that future studies evaluate the risks of lithium toxicity in susceptible groups of patients, such as those with family history of renal disease.

Lithium carbonate is a mood stabilizer that is effective in the treatment of bipolar disorder, particularly in controlling mania.¹ Lithium can reduce the risk of suicide,² treat aggression and self-mutilating behavior,³ and prevent steroid-induced psychosis.⁴ It also can raise the white cell count in patients with clozapine-induced leukopenia.⁵

To prevent or lower the risk of relapse, the therapeutic plasma level of lithium should be regularly monitored to ensure an optimal concentration in the CNS. The highest tolerable level of lithium in the plasma is 0.6 to 0.8 mmol/L, with the optimal level ranging up to 1.2 mmol/L.⁶ Regular monitoring of renal function is also required to prevent renal toxicity, particularly if the plasma level exceeds 0.8 mmol/L.⁷ Because of lithium’s relatively narrow therapeutic index, its interaction with other medications, such as angiotensin-converting enzyme inhibitors, diuretics, nonsteroidal anti-inflammatory drugs (NSAIDs), and carbamazepine, can also precipitate lithium toxicity.⁸ We describe a lesson learned from a case of lithium toxicity in an otherwise healthy patient with bipolar disorder.

Case report

An otherwise healthy 39-year-old woman diagnosed with bipolar type I disorder was receiving valproate sodium 600 mg/d and olanzapine 10 mg/d. Despite improvement in her mood, she gained 11.6 kg following 6 months of treatment. As a result, olanzapine was switched to aripiprazole 10 mg/d that was later increased to 15 mg/d, and sodium valproate was gradually optimized up to 1,000 mg/d. She later complained of hair thinning and hair loss so she self-adjusted her medication dosages, which resulted in frequent relapses. Her mood stabilizer was changed from sodium valproate to lithium 600 mg/d.

Unfortunately, after taking lithium for 15 days, she returned to us with fever associated with reduced oral intake, poor sleep, bilateral upper limb rigidity, and bilateral hand tremor. She also complained of extreme thirst and fatigue but no vomiting or diarrhea. She had difficulty falling asleep and slept for only 1 to 2 hours a day. Her symptoms worsened when a general practitioner prescribed NSAIDs for her fever and body ache. Her tremors were later generalized, which made it difficult for her to take her oral medications and disturbed her speech and movement.

On evaluation, our patient appeared comfortable and not agitated. She was orientated to time, place, and person. Her blood pressure was 139/89 mmHg, heart rate was 104 bpm, and she was afebrile. She was dehydrated with minimal urine output. She had coarse tremor in her upper and lower limbs, which were hypertonic but did not display hyperreflexia or clonus. There was no nystagmus or ataxia. A mental state examination showed no signs of manic, hypomanic, or depressive symptoms. She had slurred speech, and her affect was restricted.

Blood investigation revealed a suprathreshold lithium level of 1.70 mmol/L (normal: 0.8 to 1.2 mmol/L). Biochemical parameters showed evidence of acute kidney injury (urea: 6.1 mmol/L; creatinine: 0.140 mmol/L), with no electrolyte imbalance. There was no evidence of hypothyroidism (thyroid-stimulating hormone: 14.9 mIU/L; free thyroxine: 9.9 pmol/L), hyperparathyroidism, or hypercalcemia. Autoimmune markers were positive for antinuclear antibody (titre 1:320) and anti-double stranded DNA (76.8 IU/mL). Apart from hair loss, she denied other symptoms associated with autoimmune disease, such as joint pain, butterfly rash, or persistent fatigue. Other routine blood investigations were within normal limits. Her urine protein throughout admission had shown persistent proteinuria ranging from 3+ to 4+. Electrocardiogram (ECG) showed normal sinus rhythm with no T wave inversion or QT prolongation.

Continue to: A detailed family history...

A detailed family history later confirmed a strong family history of renal disease: her mother had lupus nephritis with nephrotic syndrome, and her brother had died from complications of a rapidly progressive glomerulonephritis. Her renal function prior to lithium initiation was within normal limits (urea: 4.0 mmol/L; serum creatinine: 78 µmol/L).

In the ward, lithium and aripiprazole were discontinued, and she was hydrated. Combined care with the psychiatric and medical teams was established early to safeguard against potential CNS deterioration. She showed marked clinical improvement by Day 3, with the resolution of coarse tremor and rigidity as well as normalization of blood parameters. Her lithium level returned to a therapeutic level by Day 4 after lithium discontinuation, and her renal profile gradually normalized. She was restarted on aripiprazole 10 mg/d for her bipolar illness and responded well. She was discharged on Day 5 with a referral to the nephrology team for further intervention.

CASE Depressed, anxious, and suicidal

Mr. J, age 72, is brought to the emergency department by law enforcement at his wife’s request due to worsening suicidal thoughts and anxiety. He has a history of major depressive disorder (MDD) and chronic kidney disease (CKD). Mr. J has been compliant with his medications, but they seem to no longer be effective. He is admitted to the geriatric psychiatry unit.

HISTORY Increased debilitation

Over the past several years, Mr. J has experienced increasing debilitation at home, including difficulty walking and an inability to perform activities of daily life. Recently, he has begun to ask for multiple pills in an attempt to take his own life.

Mr. J has been previously treated in a psychiatric clinic with duloxetine 60 mg/d, mirtazapine 30 mg/d at bedtime, buspirone 15 mg 3 times a day, and trazodone 50 mg/d at bedtime. He is also taking amlodipine 5 mg twice daily for hypertension, lisinopril 2.5 mg/d for hypertension, furosemide 20 mg/d orally for CKD, and potassium chloride 10 mEq/d for hypokalemia secondary to CKD and furosemide use. Over the past year, his psychiatric medications have been steadily increased to target his MDD and anxiety.

EVALUATION Disorientation and Stage 3A CKD

In the psychiatric unit, Mr. J describes panic, feelings of impending doom, and profound anxiety. He states he has increasing anxiety related to “being a burden” on his family and wife. Additionally, he describes decreased appetite, difficulty sleeping, low energy, difficulty concentrating, no interest in outside activities, and feelings of hopelessness.

Mr. J’s temperature is 39.2^o C; heart rate is 109 beats per minute; respiratory rate is 18 breaths per minute; blood pressure is 157/83 mm Hg; and pulse oximetry is 97%. Laboratory screening indicates a red blood cell count of 3.57, hemoglobin 11.2, hematocrit 33.8, red blood cell distribution width 17.5, blood urea nitrogen 45, creatinine 1.5 with no known baseline, and an estimated glomerular filtration rate (GFR) of 46 mL/min, indicating Stage 3A CKD (Table 1¹). Additional testing rules out other potential causes of delirium and psychosis.

A physical exam reveals Mr. J has a fine tremor, myoclonus, muscle rigidity, and hyperreflexia. He is oriented to name, but not to date, place, or situation, and is easily confused. Mr. J uses a walker but has significant tremors while walking and immediately asks for assistance due to profound anxiety related to a fear of falling. Mr. J’s mood and affect are labile with tearful and anxious episodes. His anxiety focuses on overvalued thoughts of minor or irrelevant concerns. Additionally, he has poor insight and judgment. When asked about the cause of his anxiety, Mr. J says, “I don’t know why I’m anxious; I’m just a worrywart.” His memory is impaired, and he does not know why he is in the hospital. Mr. J scores 24 on the Montreal Cognitive Assessment, which indicates mild impairment.

Mr. J continues to endorse suicidal ideation but denies homicidal thoughts. Based on these symptoms, the differential diagnosis includes serotonin syndrome, MDD with suicidal ideation, generalized anxiety disorder, and panic disorder.

The authors’ observations

GFR is used to determine the level of renal impairment. Mr. J’s GFR of 46 mL/min indicates Stage 3A CKD (Table 1¹ ). Additionally, he displayed anemia and increased creatinine due to CKD. Twenty percent of patients with CKD also experience MDD.² In a prospective observational cohort study, Hedayati et al³ found that Stage 2 to Stage 5 CKD with MDD leads to an increased risk of death, hospitalization, or progression to dialysis. It is important to properly manage Mr. J’s MDD and CKD to prevent future comorbidities. Renal impairment is common in people age >65.⁴ Even when GFR is normal, it is recommended to decrease dosing of medications in older adults due to age-related decreased renal excretion. As kidneys decrease in function, their ability to excrete normal amounts of medications also decreases, leading to increased serum levels and potential toxicity.

A combination of 4 serotonergic psychotropic medications may not be unusual to address treatment-resistant depression in a healthy, nongeriatric adult. However, Mr. J displayed signs of serotonin toxicity, such as hyperthermia, tachycardia, increased blood pressure, increased tremors, myoclonus, hyperreflexia, and muscle rigidity. These are classic signs of serotonin toxicity. For Mr. J, serotonin toxicity can be treated with the removal of serotonergic medications and lorazepam for symptom relief. If symptoms persist, cyproheptadine, a serotonin antagonist, can be used. Mr. J’s psychotropic medications were increased in an outpatient setting and he was unable to renally excrete higher doses of these serotonergic agents, which lead to chronic serotonin toxicity.

It is important to rule out other causes of psychosis or delirium in geriatric patients. A study by Marcantonio et al⁵ found that >40% of patients referred to a consulting psychiatrist for depression ultimately had delirium, and this was more likely in geriatric patients.

TREATMENT Adjustments to the medication regimen

The treatment team decides to taper and discontinue duloxetine, buspirone, and trazodone and reduce mirtazapine to 15 mg/d at bedtime. Additionally, oral lorazepam 1 mg as needed is prescribed to alleviate agitation and correct vital signs. Mr. J’s vital signs improve, with decreased temperature and normal cardiac and respiratory rhythms.

Mr. J’s Stage 3A CKD is treated with oral fluids, and his hypertension is managed with an increase of lisinopril from 2.5 mg/d to 10 mg/d. After 10 days on the psychiatric unit, he shows improvement, decreased anxiety, and remission of suicidal ideation.

The authors’ observations

In 2019, the American Geriatric Society (AGS) updated the Beers Criteria for potentially inappropriate medication use in older adults.⁴ The Beers Criteria were created to educate clinicians about the use of potentially inappropriate medications that have an unfavorable balance of benefits and risks compared to alternative treatments. The AGS lists medications that should be avoided or have their dosage reduced with varying levels of kidney function in older adults. Duloxetine is one of the medications listed with the recommendation to avoid for patients with a creatinine clearance <30 mL/min. Creatinine clearance is an estimation of GFR.

Although duloxetine is mentioned in the Beers Criteria, many other antidepressants have metabolites excreted by the kidneys.⁶ Potential adverse effects include increased bleeding, nausea, vomiting, and serotonin toxicity symptoms.⁷ Mr. J has Stage 3A CKD and takes 4 psychotropics, which will additively increase the serum concentration of serotonergic medications. In terms of treatment for serotonin toxicity, it is important to remove the causative medications. After discontinuing serotonergic medications, lorazepam can be administered as needed. If a patient continues to have symptoms, cyproheptadine is an option.

For patients with impaired renal function, adding nonpharmacologic options should be considered, such as cognitive-behavioral therapy, electroconvulsive therapy, and transcranial magnetic stimulation. Table 2^4,8-18 lists the minimum effective doses for well-known medications for treating MDD.

OUTCOME Improvement and discharge

Mr. J’s confusion improves, his heart rate decreases, and his feelings of panic and doom improve. He continues to have depressive symptoms, but his suicidal ideation stops. At discharge, Mr. J is receiving mirtazapine 15 mg/d, potassium chloride 10 mEq/d orally, lisinopril 20 mg/d orally at bedtime, furosemide 20 mg/d orally, and amlodipine 5 mg orally twice a day. Additionally, the treatment team recommends psychotherapy to Mr. J to address his anxiety and depression.

Bottom Line

Older patients are more sensitive to psychotropic medications, regardless of any comorbidities. It is important to review each patient’s glomerular filtration rate to better understand their renal function and adjust medications accordingly.

TREATMENT Adjustments to the medication regimen

The treatment team decides to taper and discontinue duloxetine, buspirone, and trazodone and reduce mirtazapine to 15 mg/d at bedtime. Additionally, oral lorazepam 1 mg as needed is prescribed to alleviate agitation and correct vital signs. Mr. J’s vital signs improve, with decreased temperature and normal cardiac and respiratory rhythms.

Mr. J’s Stage 3A CKD is treated with oral fluids, and his hypertension is managed with an increase of lisinopril from 2.5 mg/d to 10 mg/d. After 10 days on the psychiatric unit, he shows improvement, decreased anxiety, and remission of suicidal ideation.

The authors’ observations

In 2019, the American Geriatric Society (AGS) updated the Beers Criteria for potentially inappropriate medication use in older adults.⁴ The Beers Criteria were created to educate clinicians about the use of potentially inappropriate medications that have an unfavorable balance of benefits and risks compared to alternative treatments. The AGS lists medications that should be avoided or have their dosage reduced with varying levels of kidney function in older adults. Duloxetine is one of the medications listed with the recommendation to avoid for patients with a creatinine clearance <30 mL/min. Creatinine clearance is an estimation of GFR.

Although duloxetine is mentioned in the Beers Criteria, many other antidepressants have metabolites excreted by the kidneys.⁶ Potential adverse effects include increased bleeding, nausea, vomiting, and serotonin toxicity symptoms.⁷ Mr. J has Stage 3A CKD and takes 4 psychotropics, which will additively increase the serum concentration of serotonergic medications. In terms of treatment for serotonin toxicity, it is important to remove the causative medications. After discontinuing serotonergic medications, lorazepam can be administered as needed. If a patient continues to have symptoms, cyproheptadine is an option.

For patients with impaired renal function, adding nonpharmacologic options should be considered, such as cognitive-behavioral therapy, electroconvulsive therapy, and transcranial magnetic stimulation. Table 2^4,8-18 lists the minimum effective doses for well-known medications for treating MDD.

OUTCOME Improvement and discharge

Mr. J’s confusion improves, his heart rate decreases, and his feelings of panic and doom improve. He continues to have depressive symptoms, but his suicidal ideation stops. At discharge, Mr. J is receiving mirtazapine 15 mg/d, potassium chloride 10 mEq/d orally, lisinopril 20 mg/d orally at bedtime, furosemide 20 mg/d orally, and amlodipine 5 mg orally twice a day. Additionally, the treatment team recommends psychotherapy to Mr. J to address his anxiety and depression.

Bottom Line

Older patients are more sensitive to psychotropic medications, regardless of any comorbidities. It is important to review each patient’s glomerular filtration rate to better understand their renal function and adjust medications accordingly.
