An antiviral therapy in early development has the potential to prevent COVID-19 infections when given as a nasal spray as little as 4 hours before exposure. It also appears to work as a treatment if used within 4 hours after infection inside the nose, new research reveals. 

Known as TriSb92 (brand name Covidin, from drugmaker Pandemblock Oy in Finland), the viral inhibitor also appears effective against all coronavirus variants of concern, neutralizing even the Omicron variants BA.5, XBB, and BQ.1.1 in laboratory and mice studies. 

Unlike a COVID vaccine that boosts a person’s immune system as protection, the antiviral nasal spray works more directly by blocking the virus, acting as a “biological mask in the nasal cavity,” according to the biotechnology company set up to develop the treatment. 

The product targets a stable site on the spike protein of the virus that is not known to mutate. This same site is shared among many variants of the COVID virus, so it could be effective against future variants as well, researchers note.

“In animal models, by directly inactivating the virus, TriSb92 offers immediate and robust protection” against coronavirus infection and severe COVID, said Anna R. Mäkelä, PhD, lead author of the study and a senior scientist in the department of virology at the University of Helsinki. 

The study was published online in Nature Communications.
 

A potential first line of defense

Even in cases where the antiviral does not prevent coronavirus infection, the treatment could slow infection. This could happen by limiting how much virus could replicate early in the skin inside the nose and nasopharynx (the upper part of the throat), said Dr. Mäkelä, who is also CEO of Pandemblock Oy, the company set up to develop the product.

“TriSb92 could effectively tip the balance in favor of the [the person] and thereby help to reduce the risk of severe COVID-19 disease,” she said. 

The antiviral also could offer an alternative to people who cannot or do not respond to a vaccine.

“Many elderly people as well as individuals who are immunodeficient for various reasons do not respond to vaccines and are in the need of other protective measures,” said Kalle Saksela, MD, PhD, senior author of the study and a virologist at the University of Helsinki.
 

Multiple doses needed? 

TriSb92 is “one of multiple nasal spray approaches but unlikely to be as durable as effective nasal vaccines,” said Eric Topol, MD, a professor of molecular medicine and executive vice president of Scripps Research in La Jolla, Calif. Dr. Topol is also editor-in-chief of Medscape, WebMD’s sister site for medical professionals.

“The sprays generally require multiple doses per day, whereas a single dose of a nasal vaccine may protect for months,” he said.

“Both have the allure of being variant-proof,” Dr. Topol added. 
 

Thinking small

Many laboratories are shifting from treatments using monoclonal antibodies to treatments using smaller antibody fragments called “nanobodies” because they are more cost-effective and are able to last longer in storage, Dr. Mäkelä and colleagues noted. 

Several of these nanobodies have shown promise against viruses in cell culture or animal models, including as an intranasal preventive treatment for SARS-CoV-2. 

One of these smaller antibodies is being developed from llamas for example; another comes from experiments with yeast to develop synthetic nanobodies; and in a third case, researchers isolated nanobodies from llamas and from mice and showed they could neutralize the SARS-CoV-2 virus.

These nanobodies and TriSb92 target a specific part of the coronavirus spike protein called the receptor-binding domain (RBD). The RBD is where the coronavirus attaches to cells in the body. These agents essentially trick the virus by changing the structure of the outside of cells, so they look like a virus has already fused to them. This way, the virus moves on. 
 

Key findings

The researchers compared mice treated with TriSb92 before and after exposure to SARS-CoV-2. When given in advance, none of the treated mice had SARS-CoV-2 RNA in their lungs, while untreated mice in the comparison group had “abundant” levels.

Other evidence of viral infection showed similar differences between treated and untreated mice in the protective lining of cells called the epithelium inside the nose, nasal mucosa, and airways. 

Similarly, when given 2 or 4 hours after SARS-CoV-2 had already infected the epithelium, TriSb92 was linked to a complete lack of the virus’s RNA in the lungs.

It was more effective against the virus, though, when given before infection rather than after, “perhaps due to the initial establishment of the infection,” the researchers note.

The company led by Dr. Mäkelä is now working to secure funding for clinical trials of TriSb92 in humans.

Cluster headache and migraine have strong ties to the circadian system at multiple levels, say new findings that could have significant treatment implications.

A meta-analysis of 16 studies showed a circadian pattern in 71% of cluster headache attacks (3,490 of 4,953), with a clear circadian peak between 9:00 p.m. and 3:00 a.m.

Migraine was also associated with a circadian pattern in 50% of cases (2,698 of 5,385) across eight studies, with a clear circadian trough between 11:00 p.m. and 7:00 a.m.

Seasonal peaks were also evident for cluster headache (spring and autumn) and migraine (April to October).

“In the short term, these findings help us explain the timing to patients – for example, it is possible that a headache at 8 a.m. is due to their internal body clock instead of their pillow, or breakfast food, or morning medications,” lead investigator Mark Burish, MD, PhD, associate professor, department of neurosurgery, at University of Texas Health Houston, told this news organization.

“In the long term, these findings do suggest that medications that target the circadian system could be effective in migraine and headache patients,” Dr. Burish added.

The study was published online in Neurology.


 

Treatment implications?

Across studies, chronotype was “highly variable” for both cluster headache and migraine, the investigators report.

Cluster headache was associated with lower melatonin and higher cortisol levels, compared with non–cluster headache controls.

On a genetic level, cluster headache was associated with two core circadian genes (CLOCK and REV-ERB–alpha), and five of the nine genes that increase the likelihood of having cluster headache are genes with a circadian pattern of expression.

Migraine headache was associated with lower urinary melatonin levels and with the core circadian genes, CK1-delta and ROR-alpha, and 110 of the 168 genes associated with migraine were clock-controlled genes.

“The data suggest that both of these headache disorders are highly circadian at multiple levels, especially cluster headache,” Dr. Burish said in a release.

“This reinforces the importance of the hypothalamus – the area of the brain that houses the primary biological clock – and its role in cluster headache and migraine. It also raises the question of the genetics of triggers such as sleep changes that are known triggers for migraine and are cues for the body’s circadian rhythm,” Dr. Burish said.

“We hope that future research will look into circadian medications as a new treatment option for migraine and cluster headache patients,” Dr. Burish told this news organization.
 

Importance of sleep regulation

The authors of an accompanying editorial note that even though the study doesn’t have immediate clinical implications, it offers a better understanding of the way chronobiologic factors may influence treatment.

“At a minimum, interventions known to regulate and improve sleep (e.g., melatonin, cognitive behavioral therapy), and which are safe and straightforward to introduce, may be useful in some individuals susceptible to circadian misalignment or sleep disorders,” write Heidi Sutherland, PhD, and Lyn Griffiths, PhD, with Queensland University of Technology, Brisbane, Australia.

“Treatment of comorbidities (e.g., insomnia) that result in sleep disturbances may also help headache management. Furthermore, chronobiological aspects of any pharmacological interventions should be considered, as some frequently used headache and migraine drugs can modulate circadian cycles and influence the expression of circadian genes (e.g., verapamil), or have sleep-related side effects,” they add.

A limitation of the study was the lack of information on factors that could influence the circadian cycle, such as medications; other disorders, such as bipolar disorder; or circadian rhythm issues, such as night-shift work.

The study was supported by grants from the Japan Society for the Promotion of Science, the National Institutes of Health, The Welch Foundation, and The Will Erwin Headache Research Foundation. Dr. Burish is an unpaid member of the medical advisory board of Clusterbusters, and a site investigator for a cluster headache clinical trial funded by Lundbeck. Dr. Sutherland has received grant funding from the U.S. Migraine Research Foundation, and received institute support from Queensland University of Technology for genetics research. Dr. Griffiths has received grant funding from the Australian NHMRC, U.S. Department of Defense, and the U.S. Migraine Research Foundation, and consultancy funding from TEVA.

A former manager at the Philadelphia Veterans Affairs Medical Center (VAMC) has been sentenced to 6 months in federal prison for his part in a bribery scheme.

Ralph Johnson was convicted of accepting $30,000 in kickbacks and bribes for steering contracts to Earron and Carlicha Starks, who ran Ekno Medical Supply and Collondale Medical Supply from 2009 to 2019. Johnson served as chief of environmental services at the medical center. He admitted to receiving cash in binders and packages mailed to his home between 2018 and 2019.

The Starkses pleaded guilty first to paying kickbacks on $7 million worth of contracts to Florida VA facilities, then participated in a sting that implicated Johnson.

The VA Office of Inspector General began investigating Johnson in 2018 after the Starkses, who were indicted for bribing staff at US Department of Veterans Affairs (VA) hospitals in Miami and West Palm Beach, Florida, said they also paid officials in VA facilities on the East Coast.

According to the Philadelphia Inquirer, the judge credited Johnson’s past military service and his “extensive cooperation” with federal authorities investigating fraud within the VA. Johnson apologized to his former employers: “Throughout these 2 and a half years [since the arrest] there’s not a day I don’t think about the wrongness that I did.”

In addition to the prison sentence, Johnson has been ordered to pay back, at $50 a month, the $440,000-plus he cost the Philadelphia VAMC in fraudulent and bloated contracts.

Johnson is at least the third Philadelphia VAMC employee indicted or sentenced for fraud since 2020.

If Miley Cyrus has planted “Flowers” in your head, rest assured you’re not alone.

An earworm – a bit of music you can’t shake from your brain – happens to almost everyone. 

The culprit is typically a song you’ve heard repeatedly with a strong rhythm and melody (like Miley’s No. 1 hit this year).

It pops into your head and stays there, unbidden and often unwanted. As you fish for something new on Spotify, there’s always a chance that a catchy hook holds an earworm.

“A catchy tune or melody is the part of a song most likely to get stuck in a person’s head, often a bit from the chorus,” said Elizabeth H. Margulis, PhD, a professor at Princeton (N.J.) University and director of its music cognition lab. The phenomenon, which has been studied since 1885 (way before earbuds), goes by such names as stuck song syndrome, sticky music, musical imagery repetition, intrusive musical imagery, or the semi-official term, involuntary musical imagery, or INMI.

Research confirms how common it is. A 2020 study of American college students found that 97% had experienced an earworm in the past month, similar to findings from a larger Finnish survey done more than 10 years ago.

One in five people had experienced an earworm more than once a day, the study found. The typical length was 10-30 minutes, though 8.5% said theirs lasted more than 3 hours. Levels of “distress and interference” that earworms caused was mostly “mild to moderate.” 

Some 86% said they tried to stop it – most frequently by distraction, like talking to a friend or listening to another song.

If music is important to you, your earworms are more likely to last longer and be harder to control, earlier research found. And women are thought to be more likely to have them.

“Very musical people may have more earworms because it’s easy for them to conjure up a certain tune,” says David Silbersweig, MD, chairman of the department of psychiatry and codirector of the Institute for the Neurosciences at Brigham and Women’s Hospital in Boston.

Moreover, people who lack “psychological flexibility” may find earworms more bothersome. The more they try to avoid or control intrusive thoughts (or songs), the more persistent those thoughts become. 

“This is consistent with OCD (obsessive-compulsive disorder) research on the paradoxical effect of thought suppression,” the authors of the 2020 study wrote. In fact, people who report very annoying or stressful earworms are more likely to have obsessive-compulsive symptoms.

Earworms have been linked to other medical conditions as well, and even harmless earworms can be intrusive and time-consuming. That makes them worth a closer look.

Digging for the source of earworms

Scientists trace earworms to the auditory cortex in the temporal lobe of the brain, which controls how you perceive music, as well as deep temporal lobe areas that are responsible for retrieving memories. Your amygdala and ventral striatum, parts of your brain that involve emotion, also tie into the making of an earworm.

MRI experiments found that “INMI is a common internal experience recruiting brain networks involved in perception, emotions, memory and spontaneous thoughts,” a 2015 paper in  Consciousness and Cognition  reported.

These brain networks work in tandem if you connect a song to an emotional memory – that’s when you’re more likely to experience it as an earworm. The “loop” of music you’ll hear in your head is usually a 20-second snippet.

Think of it as a “cognitive itch,” as researchers from the Netherlands put it. An earworm can be triggered by associating a song with a specific situation or emotion. Trying to suppress it just reminds you it’s there, “scratching” the itch and making it worse. “The more one tries to suppress the songs, the more their impetus increases, a mental process known as ironic process theory,” they wrote. 

“It’s also worth pointing out that earworms don’t always occur right after a song ends,” said Michael K. Scullin, PhD, an associate professor of psychology and neuroscience at Baylor University in Waco, Tex. “Sometimes they only occur many hours later, and sometimes the earworm isn’t the song you were most recently listening to.”

These processes aren’t fully understood, he said, “but they likely represent memory consolidation mechanisms; that is, the brain trying to reactivate and stabilize musical memories.” Kind of like switching “radio stations” in your head. 

When to worry

Earworms are most often harmless. “They’re part of a healthy brain,” said Dr. Silbersweig. But in rare cases, they indicate certain medical conditions. People with OCD, for example, have been shown to have earworms during times of stress. If this is the case, cognitive-behavioral therapy as well as some antidepressants may help.

Take an earworm seriously if it’s linked to other symptoms, said Elaine Jones, MD, a neurologist in Hilton Head, S.C., and a fellow of the American Academy of Neurology. Those symptoms could include “loss of consciousness or confusion, visual loss or changes, speech arrest, tremors of arms or legs,” she said.

“Most worrisome would be a seizure, but other causes could include a migraine aura. In a younger person, less than 20 years old, this kind of earworm could indicate a psychiatric condition like schizophrenia.” Drug toxicity or brain damage can also present with earworms.

Her bottom line: “If an earworm is persistent for more than 24 hours, or if it is associated with the other symptoms mentioned above, it would be important to reach out to your primary care doctor to ensure that nothing more serious is going on,” said Dr. Jones. With no other symptoms, “it is more likely to be just an earworm.”

Japanese research also indicates that an earworm that lasts for several hours in a day can be linked to depression. If a person has symptoms such as low mood, insomnia, and loss of appetite, along with earworms that last several hours a day, treatment may help. 

There’s another category called “musical hallucinations” – where the person thinks they are actually hearing music, which could be a symptom of depression, although scientists don’t know for sure. The drug vortioxetine, which may help boost serotonin in the brain, has shown some promise in reducing earworms. 

Some research has shown that diseases that damage the auditory pathway in the brain have a link to musical hallucinations. 

How to stop a simple earworm

Here are six easy ways to make it stop:

• Mix up your playlist. “Listening to songs repeatedly does increase the likelihood that they’ll get stuck,” said Dr. Margulis. 
• Take breaks from your tunes throughout the day. “Longer listening durations are more likely to lead to earworms,” Dr. Scullin said.
• Use your feet. than the beat of your earworm. This will interrupt your memory of the tempo and can help chase away the earworm.
• Stick with that song. “Listen to a song all the way through,” said Dr. Silbersweig. If you only listen to snippets of a song, the  can take hold. That’s the brain’s tendency to remember things that are interrupted more easily than completed things.
• Distract yourself. Lose yourself in a book, a movie, your work, or a hobby that requires concentration. “Redirecting attention to an absorbing task can be an effective way to dislodge an earworm,” said Dr. Margulis. 
• Chew gum.  shows that the action of doing so interferes with repetitive memories and stops your mind from “scanning” a song. Then enjoy the sound of silence!

If Miley Cyrus has planted “Flowers” in your head, rest assured you’re not alone.

An earworm – a bit of music you can’t shake from your brain – happens to almost everyone. 

The culprit is typically a song you’ve heard repeatedly with a strong rhythm and melody (like Miley’s No. 1 hit this year).

It pops into your head and stays there, unbidden and often unwanted. As you fish for something new on Spotify, there’s always a chance that a catchy hook holds an earworm.

“A catchy tune or melody is the part of a song most likely to get stuck in a person’s head, often a bit from the chorus,” said Elizabeth H. Margulis, PhD, a professor at Princeton (N.J.) University and director of its music cognition lab. The phenomenon, which has been studied since 1885 (way before earbuds), goes by such names as stuck song syndrome, sticky music, musical imagery repetition, intrusive musical imagery, or the semi-official term, involuntary musical imagery, or INMI.

Research confirms how common it is. A 2020 study of American college students found that 97% had experienced an earworm in the past month, similar to findings from a larger Finnish survey done more than 10 years ago.

One in five people had experienced an earworm more than once a day, the study found. The typical length was 10-30 minutes, though 8.5% said theirs lasted more than 3 hours. Levels of “distress and interference” that earworms caused was mostly “mild to moderate.” 

Some 86% said they tried to stop it – most frequently by distraction, like talking to a friend or listening to another song.

If music is important to you, your earworms are more likely to last longer and be harder to control, earlier research found. And women are thought to be more likely to have them.

“Very musical people may have more earworms because it’s easy for them to conjure up a certain tune,” says David Silbersweig, MD, chairman of the department of psychiatry and codirector of the Institute for the Neurosciences at Brigham and Women’s Hospital in Boston.

Moreover, people who lack “psychological flexibility” may find earworms more bothersome. The more they try to avoid or control intrusive thoughts (or songs), the more persistent those thoughts become. 

“This is consistent with OCD (obsessive-compulsive disorder) research on the paradoxical effect of thought suppression,” the authors of the 2020 study wrote. In fact, people who report very annoying or stressful earworms are more likely to have obsessive-compulsive symptoms.

Earworms have been linked to other medical conditions as well, and even harmless earworms can be intrusive and time-consuming. That makes them worth a closer look.

Digging for the source of earworms

Scientists trace earworms to the auditory cortex in the temporal lobe of the brain, which controls how you perceive music, as well as deep temporal lobe areas that are responsible for retrieving memories. Your amygdala and ventral striatum, parts of your brain that involve emotion, also tie into the making of an earworm.

MRI experiments found that “INMI is a common internal experience recruiting brain networks involved in perception, emotions, memory and spontaneous thoughts,” a 2015 paper in  Consciousness and Cognition  reported.

Just 16% of psoriasis-related visits to dermatology providers in the United States involve screening for cardiovascular (CV) risk factors, with screening lowest in the region with the highest CV disease burden, according to an analysis of 10 years of national survey data.

From 2007 to 2016, national screening rates for four CV risk factors at 14.8 million psoriasis-related visits to dermatology providers were 11% (body-mass index), 7.4% (blood pressure), 2.9% (cholesterol), and 1.7% (glucose). Data from the National Ambulatory Medical Care Survey showed that at least one of the four factors was screened at 16% of dermatology visits, said William B. Song, BS, of the department of dermatology, University of Pennsylvania, Philadelphia, and associates.

The main focus of their study, however, was regional differences. “CV risk factor screening by dermatology providers for patients with psoriasis is low across all regions of the United States and lowest in the South, the region that experiences the highest CVD burden in the United States,” they wrote in a letter to the editor.

Compared with the South, the adjusted odds of any CV screening were 0.98 in the West, 1.25 in the Northeast, and 1.92 in the Midwest. Blood pressure screening was significantly higher in all three regions, compared with the South, while BMI screening was actually lower in the West (0.74), the investigators reported. Odds ratios were not available for cholesterol and glucose screening because of sample size limitations.

The regional variation in screening rates “is not explained by patient demographics or disease severity,” they noted, adding that 2.8 million visits with BP screening would have been added over the 10-year study period “if providers in the South screened patients with psoriasis for high blood pressure at the same rate as providers in the Northeast.”

Guidelines published in 2019 by the American Academy of Dermatology and the National Psoriasis Foundation – which were cowritten by Joel M. Gelfand, MD, senior author of the current study – noted that dermatologists “play an important role in evidence-based screening of CV risk factors in patients with psoriasis,” the investigators wrote. But the regional variations suggest “that some regions experience barriers to appropriate screening or challenges in adhering to guidelines for managing psoriasis and CV risk.”

While the lack of data from after 2016 is one of the study limitations, they added, “continued efforts to develop effective interventions to improve CV screening and care for people with psoriasis in all regions of the U.S. are needed to more effectively address the burden of CV disease experienced by people with psoriasis.”

The study was partly funded by the National Psoriasis Foundation. Three of the seven investigators disclosed earnings from private companies in the form of consultant fees, research support, and honoraria. Dr. Gelfand is a deputy editor for the Journal of Investigative Dermatology.

Over-the-scope clips (OTSC) may prevent further bleeding more so than standard endoscopic treatment when used as primary treatment in patients with high-risk nonvariceal upper gastrointestinal lesions, shows a randomized controlled trial (RCT).

However, noted the investigators, writing in Annals of Internal Medicine, and physicians who wrote an accompanying editorial, reservations remain about first-line use of OTSCs, but mostly relate to method, technique, and cost.

“The absolute difference in the rate of further bleeding was 11.4 percentage points. We should however be cautious in our recommendation of using OTSC as first-line treatment,” wrote researchers who were led by James Y.W. Lau, MD, from Prince of Wales Hospital, Chinese University of Hong Kong.

“The primary use of OTSCs may find a role in the treatment of ulcers predicted to fail standard endoscopic treatment,” the authors wrote.  However, they emphasized that, “We are not advocating routine primary use of OTSCs. These clips are costly, and a formal cost analysis is not available in the literature. The use of OTSCs involves scope withdrawal, mounting of the OTSCs, and scope reinsertion, which increase the procedure time. Endoscopists also require training before using OTSCs.”

Alan N. Barkun, MD, gastroenterologist and professor of medicine with McGill University, Montreal, who cowrote the editorial accompanying the research paper, said the study investigators were highly experienced surgeon-scientists, pointing out that, overall, first-line use of OTSC in this patient group improved patient outcomes.

“The main message here is that if you can position the clip properly, then it is likely to stay in place, better than standard approaches,” he said, adding that, “I support it fully for second-line use but there currently still exists uncertainty for routine first-line adoption in nonvariceal bleeding. Clinicians fail to position the clip properly in around 5% of patients which is higher than standard endoscopic approaches, and nobody has yet clearly defined the lesions that are difficult to clip with the OTSC.

“If you’re going to tell people to use it, then you need to tell them with which particular lesions OTSC works best as first-line approach,” he added.

Lesions of concern include upon leaving the stomach and entering the duodenum, and in passing from the first to the second stage of the duodenum. “These are tight areas, and these larger full-thickness bite OTSC may create pseudo-polyps, even possibly causing obstruction. Perforation is also a risk.” One of each of these complications were noted in this study.

The study included 190 adult patients with active bleeding or a nonbleeding visible vessel from a nonvariceal cause on upper gastrointestinal endoscopy. Of these, 97 patients received standard hemostatic treatment and 93 received OTSC. The primary endpoint of a 30-day probability of further bleeding was 14.6% in the standard treatment and 3.2% in the OTSC group (risk difference, 11.4 percentage points [95% confidence interval (CI), 3.3-20.0 percentage points]; P = .006). Failure to control bleeding after assigned endoscopic treatment in the standard treatment and OTSC groups was 6 versus 1 in the standard treatment and OTSC groups, respectively. Thirty-day recurrent bleeding was 8 versus 2 in the standard treatment and OTSC groups, respectively. Eight patients in the standard treatment group needed further intervention compared with two in the OTSC group. Thirty-day mortality was four versus two, respectively.

“First-line OTSC has a role to play but whether it is the best approach is hard to say due to methodological limitations that were seen in this and earlier studies, however if you can position the clip properly it likely does well,” Dr. Barkun said.

Dr. Lau declares that he received honorarium for a lecture from OVESCO. Dr. Li has no disclosures. Dr. Barkun has no relevant disclosures.

Failure to control bleeding after assigned endoscopic treatment in the standard treatment and OTSC groups was 6 versus 1 in the standard treatment and OTSC groups, respectively. Thirty-day recurrent bleeding was 8 versus 2 in the standard treatment and OTSC groups, respectively. Eight patients in the standard treatment group needed further intervention compared with two in the OTSC group. Thirty-day mortality was four versus two, respectively.

“First-line OTSC has a role to play but whether it is the best approach is hard to say due to methodological limitations that were seen in this and earlier studies, however if you can position the clip properly it likely does well,” Dr. Barkun said.

Over-the-scope clips (OTSC) may prevent further bleeding more so than standard endoscopic treatment when used as primary treatment in patients with high-risk nonvariceal upper gastrointestinal lesions, shows a randomized controlled trial (RCT).

However, noted the investigators, writing in Annals of Internal Medicine, and physicians who wrote an accompanying editorial, reservations remain about first-line use of OTSCs, but mostly relate to method, technique, and cost.

“The absolute difference in the rate of further bleeding was 11.4 percentage points. We should however be cautious in our recommendation of using OTSC as first-line treatment,” wrote researchers who were led by James Y.W. Lau, MD, from Prince of Wales Hospital, Chinese University of Hong Kong.

“The primary use of OTSCs may find a role in the treatment of ulcers predicted to fail standard endoscopic treatment,” the authors wrote.  However, they emphasized that, “We are not advocating routine primary use of OTSCs. These clips are costly, and a formal cost analysis is not available in the literature. The use of OTSCs involves scope withdrawal, mounting of the OTSCs, and scope reinsertion, which increase the procedure time. Endoscopists also require training before using OTSCs.”

Alan N. Barkun, MD, gastroenterologist and professor of medicine with McGill University, Montreal, who cowrote the editorial accompanying the research paper, said the study investigators were highly experienced surgeon-scientists, pointing out that, overall, first-line use of OTSC in this patient group improved patient outcomes.

“The main message here is that if you can position the clip properly, then it is likely to stay in place, better than standard approaches,” he said, adding that, “I support it fully for second-line use but there currently still exists uncertainty for routine first-line adoption in nonvariceal bleeding. Clinicians fail to position the clip properly in around 5% of patients which is higher than standard endoscopic approaches, and nobody has yet clearly defined the lesions that are difficult to clip with the OTSC.

“If you’re going to tell people to use it, then you need to tell them with which particular lesions OTSC works best as first-line approach,” he added.

Lesions of concern include upon leaving the stomach and entering the duodenum, and in passing from the first to the second stage of the duodenum. “These are tight areas, and these larger full-thickness bite OTSC may create pseudo-polyps, even possibly causing obstruction. Perforation is also a risk.” One of each of these complications were noted in this study.

The study included 190 adult patients with active bleeding or a nonbleeding visible vessel from a nonvariceal cause on upper gastrointestinal endoscopy. Of these, 97 patients received standard hemostatic treatment and 93 received OTSC. The primary endpoint of a 30-day probability of further bleeding was 14.6% in the standard treatment and 3.2% in the OTSC group (risk difference, 11.4 percentage points [95% confidence interval (CI), 3.3-20.0 percentage points]; P = .006). Failure to control bleeding after assigned endoscopic treatment in the standard treatment and OTSC groups was 6 versus 1 in the standard treatment and OTSC groups, respectively.

High-dose prophylactic anticoagulation or therapeutic anticoagulation reduced de novo thrombosis in patients with hypoxemic COVID-19 pneumonia, based on data from 334 adults.

Patients with hypoxemic COVID-19 pneumonia are at increased risk of thrombosis and anticoagulation-related bleeding, therefore data to identify the lowest effective anticoagulant dose are needed, wrote Vincent Labbé, MD, of Sorbonne University, Paris, and colleagues.

Previous studies of different anticoagulation strategies for noncritically ill and critically ill patients with COVID-19 pneumonia have shown contrasting results, but some institutions recommend a high-dose regimen in the wake of data showing macrovascular thrombosis in patients with COVID-19 who were treated with standard anticoagulation, the authors wrote.

However, no previously published studies have compared the effectiveness of the three anticoagulation strategies: high-dose prophylactic anticoagulation (HD-PA), standard dose prophylactic anticoagulation (SD-PA), and therapeutic anticoagulation (TA), they said.

In the open-label Anticoagulation COVID-19 (ANTICOVID) trial, published in JAMA Internal Medicine, the researchers identified consecutively hospitalized adults aged 18 years and older being treated for hypoxemic COVID-19 pneumonia in 23 centers in France between April 2021 and December 2021.

The patients were randomly assigned to SD-PA (116 patients), HD-PA (111 patients), and TA (112 patients) using low-molecular-weight heparin for 14 days, or until either hospital discharge or weaning from supplemental oxygen for 48 consecutive hours, whichever outcome occurred first.  The HD-PA patients received two times the SD-PA dose. The mean age of the patients was 58.3 years, and approximately two-thirds were men; race and ethnicity data were not collected. Participants had no macrovascular thrombosis at the start of the study.

The primary outcomes were all-cause mortality and time to clinical improvement (defined as the time from randomization to a 2-point improvement on a 7-category respiratory function scale).

The secondary outcome was a combination of safety and efficacy at day 28 that included a composite of thrombosis (ischemic stroke, noncerebrovascular arterial thrombosis, deep venous thrombosis, pulmonary artery thrombosis, and central venous catheter–related deep venous thrombosis), major bleeding, or all-cause death.

For the primary outcome, results were similar among the groups; HD-PA had no significant benefit over SD-PA or TA. All-cause death rates for SD-PA, HD-PA, and TA patients were 14%, 12%, and 13%, respectively. The time to clinical improvement for the three groups was approximately 8 days, 9 days, and 8 days, respectively. Results for the primary outcome were consistent across all prespecified subgroups.

However, HD-PA was associated with a significant fourfold reduced risk of de novo thrombosis compared with SD-PA (5.5% vs. 20.2%) with no observed increase in major bleeding. TA was not associated with any significant improvement in primary or secondary outcomes compared with HD-PA or SD-PA.

The current study findings of no improvement in survival or disease resolution in patients with a higher anticoagulant dose reflects data from previous studies, the researchers wrote in their discussion. “Our study results together with those of previous RCTs support the premise that the role of microvascular thrombosis in worsening organ dysfunction may be narrower than estimated,” they said.

The findings were limited by several factors including the open-label design and the relatively small sample size, the lack of data on microvascular (vs. macrovascular) thrombosis at baseline, and the predominance of the Delta variant of COVID-19 among the study participants, which may have contributed to a lower mortality rate, the researchers noted.

However, given the significant reduction in de novo thrombosis, the results support the routine use of HD-PA in patients with severe hypoxemic COVID-19 pneumonia, they concluded.
 

Results inform current clinical practice

Over the course of the COVID-19 pandemic, “Patients hospitalized with COVID-19 manifested the highest risk for thromboembolic complications, especially patients in the intensive care setting,” and early reports suggested that standard prophylactic doses of anticoagulant therapy might be insufficient to prevent thrombotic events, Richard C. Becker, MD, of the University of Cincinnati, and Thomas L. Ortel, MD, of Duke University, Durham, N.C., wrote in an accompanying editorial.

“Although there have been several studies that have investigated the role of anticoagulant therapy in hospitalized patients with COVID-19, this is the first study that specifically compared a standard, prophylactic dose of low-molecular-weight heparin to a ‘high-dose’ prophylactic regimen and to a full therapeutic dose regimen,” Dr. Ortel said in an interview.

“Given the concerns about an increased thrombotic risk with prophylactic dose anticoagulation, and the potential bleeding risk associated with a full therapeutic dose of anticoagulation, this approach enabled the investigators to explore the efficacy and safety of an intermediate dose between these two extremes,” he said.

In the current study, “It was notable that the primary driver of the improved outcomes with the ‘high-dose’ prophylactic regimen reflected the fourfold reduction in macrovascular thrombosis, a finding that was not observed in other studies investigating anticoagulant therapy in hospitalized patients with severe COVID-19,” Dr. Ortel told this news organization. “Much initial concern about progression of disease in patients hospitalized with severe COVID-19 focused on the role of microvascular thrombosis, which appears to be less important in this process, or, alternatively, less responsive to anticoagulant therapy.”

The clinical takeaway from the study, Dr. Ortel said, is the decreased risk for venous thromboembolism with a high-dose prophylactic anticoagulation strategy compared with a standard-dose prophylactic regimen for patients hospitalized with hypoxemic COVID-19 pneumonia, “leading to an improved net clinical outcome.”

Looking ahead, “Additional research is needed to determine whether a higher dose of prophylactic anticoagulation would be beneficial for patients hospitalized with COVID-19 pneumonia who are not in an intensive care unit setting,” Dr. Ortel said. Studies are needed to determine whether therapeutic interventions are equally beneficial in patients with different coronavirus variants, since most patients in the current study were infected with the Delta variant, he added.

CASE A difficult withdrawal

Three days after he stops drinking alcohol, Mr. G, age 49, presents to a detoxification center with his wife, who drove him there because she was concerned about his condition. She says her husband had been drinking alcohol every night for as long as she can remember. Despite numerous admissions to rehabilitation centers, Mr. G usually would resume drinking soon after he was discharged. Three days ago, Mr. G’s wife had told him she “could not take it anymore,” so he got rid of all his alcohol and stopped drinking. Mr. G’s wife felt he was doing fine the first day, but his condition increasingly worsened the second and third days. The triage nurse who attempts to interview Mr. G finds him tremulous, vomiting, and sweating. She notices that he seems preoccupied with pulling at his shirt, appearing to pick at things that are not there.

HISTORY Untreated depression, other comorbidities

Mr. G’s wife says he has never been psychiatrically hospitalized or exhibited suicidal behavior. Mr. G previously received care from a psychiatrist, who diagnosed him with major depressive disorder (MDD) and prescribed an antidepressant, though his wife cannot recall which specific medication. She shares it has been “a long time” since Mr. G has taken the antidepressant and the last time he received treatment for his MDD was 5 years ago. Mr. G’s wife says her husband had once abstained from alcohol use for >6 months following one of his stints at a rehabilitation center. She is not able to share many other details about Mr. G’s previous stays at rehabilitation centers, but says he always had “a rough time.”

She says Mr. G had been drinking an average of 10 drinks each night, usually within 4 hours. He has no history of nicotine or illicit substance use and has held a corporate job for the last 18 years. Several years ago, a physician had diagnosed Mr. G with hypertension and high cholesterol, but he did not follow up for treatment. Mr. G’s wife also recalls a physician told her husband he had a fatty liver. His family history includes heart disease and cancer.

The author’s observations

The treatment team observed several elements of alcohol withdrawal and classified Mr. G as a priority patient. If the team had completed the Clinical Institute Withdrawal Assessment for Alcohol–Revised scale (CIWA-Ar) (Table 1¹), Mr. G would score ≥10. While the protocol for initiating treatment for patients experiencing alcohol withdrawal varies by institution, patients with moderate to severe scores on the CIWA-Ar when experiencing withdrawal typically are managed with pharmacotherapy to address their symptoms.¹ Given the timeline of his last drink as reported by his wife, Mr. G is on the brink of experiencing a cascade of symptoms concerning for delirium tremens (DTs).² Table 2² provides a timeline and symptoms related to alcohol withdrawal. To prevent further exacerbation of symptoms, which could lead to DTs, Mr. G’s treatment team will likely initiate a benzodiazepine, using either scheduled or symptom-driven dosing.³

Two neurotransmitters that play a role in DTs are glutamate (excitatory) and GABA (inhibitory). In a normal state, the competing actions of these neurotransmitters balance each other. Acute alcohol intake causes a shift in the excitatory and inhibitory levels, with more inhibition taking place, thus causing disequilibrium. If chronic alcohol use continues, the amount of GABA inhibition reduction is related to downregulation of receptors.^2,4 Excitation increases by way of upregulation of the N-methyl-D-aspartate receptors.^2,4,5 The goal is to achieve equilibrium of the neurotransmitters, even though the balance is different from when alcohol was not present.^2,4

If alcohol is suddenly removed following chronic use, there is unchecked glutamate excitation related to a blunted GABA state. This added increase in the excitation of glutamate leads to withdrawal symptoms.^2,4 Table 3^2,4,5 depicts the neuro­transmitter equilibrium of GABA and glutamate relative to alcohol use.

EVALUATION Bleeding gums and bruising

The treatment team admits Mr. G to the triage bay and contacts the addiction psychiatrist. The physician orders laboratory tests to assess nutritional deficits and electrolyte abnormalities. Mr. G is also placed on routine assessments with symptom-triggered therapy. An assessment reveals bleeding gums and bruises, which are believed to be a result of thrombocytopenia (low blood platelet count).

The author’s observations

Though regular clinical assessment of PEth varies, it is considered to have high sensitivity and specificity to detect alcohol use.⁶ When ethanol is present, the phospholipase D enzyme acts upon phosphatidylcholine, forming a direct biomarker, PEth, on the surface of the red blood cell.^6,7 PEth’s half-life ranges from 4.5 to 12 days,⁶ and it can be detected in blood for 3 to 4 weeks after alcohol ingestion.^6,7 A PEth value <20 ng/mL indicates light or no alcohol consumption; 20 to 199 ng/mL indicates significant consumption; and >200 ng/mL indicates heavy consumption.⁷ Since Mr. G has a history of chronic alcohol use, his PEth level is expected to be >200 ng/mL.

AST/ALT and MCV are indirect biomarkers, meaning the tests are not alcohol-specific and the role of alcohol is instead observed by the damage to the body with excessive use over time.⁷ The expected AST:ALT ratio is 2:1. This is related to 3 mechanisms. The first is a decrease in ALT usually relative to B6 deficiency in individuals with alcohol use disorder (AUD). Another mechanism is related to alcohol’s propensity to affect mitochondria, which is a source for AST. Additionally, AST is also found in higher proportions in the kidneys, heart, and muscles.⁸

An MCV <100 fL would be within the normal range (80 to 100 fL) for red blood cells. While the reasons for an enlarged red blood cell (or macrocyte) are extensive, alcohol can be a factor once other causes are excluded. Additional laboratory tests and a peripheral blood smear test can help in this investigation. Alcohol disrupts the complete maturation of red blood cells.^9,10 If the cause of the macrocyte is alcohol-related and alcohol use is terminated, those enlarged cells can resolve in an average of 3 months.⁹

Vitamin B1 levels >200 nmol/L would be within normal range (74 to 222 nmol/L). Mr. G’s chronic alcohol use would likely cause him to be vitamin B1–deficient. The deficiency is usually related to diet, malabsorption, and the cells’ impaired ability to utilize vitamin B1. A consequence of vitamin B1 deficiency is Wernicke-Korsakoff syndrome.¹¹

Due to his chronic alcohol use, Mr. G’s magnesium stores most likely would be below normal range (1.7 to 2.2 mg/dL). Acting as a diuretic, alcohol depletes magnesium and other electrolytes. The intracellular shift that occurs to balance the deficit causes the body to use its normal stores of magnesium, which leads to further magnesium depletion. Other common causes include nutritional deficiency and decreased gastrointestinal absorption.¹² The bleeding the physician suspected was a result of drinking likely occurred through direct and indirect mechanisms that affect platelets.^9,13 Platelets can show improvement 1 week after drinking cessation. Some evidence suggests the risk of seizure or DTs increases significantly with a platelet count <119,000 µL per unit of blood.¹³

Continue to: TREATMENT Pharmacotherapy for alcohol use disorder

TREATMENT Pharmacotherapy for alcohol use disorder

As Mr. G’s condition starts to stabilize, he discusses treatment options for AUD with his physician. At the end of the discussion, Mr. G expresses an interest in starting a medication. The doctor reviews his laboratory results and available treatment options.

[polldaddy:12041630]

The author’s observations

Of the 3 FDA-approved medications for treating AUD (disulfiram, acamprosate, and naltrexone), naltrexone has been shown to decrease heavy drinking days^5,14 and comes in oral and injectable forms. Reducing drinking is achieved by reducing the rewarding effects of alcohol^5,14 and alcohol cravings.⁵ Disulfiram often has poor adherence, and like acamprosate it may be more helpful for maintenance of abstinence. Neither topiramate nor gabapentin are FDA-approved for AUD but may be used for their affects on GABA.⁵ Gabapentin may also help patients experiencing alcohol withdrawal syndrome.^5,15 Mr. G did not have any concomitant medications or comorbid medical conditions, but these factors as well as any renal or hepatic dysfunction must be considered before initiating any medications.

OUTCOME Improved well-being

Mr. G’s treatment team initiates oral naltrexone 50 mg/d, which he tolerates well without complications. He stops drinking entirely and expresses an interest in transitioning to an injectable form of naltrexone in the future. In addition to taking medication, Mr. G wants to participate in psychotherapy. Mr. G thanks his team for the care he received in the hospital, telling them, “You all saved my life.” As he discusses his past issues with alcohol, Mr. G asks his physician how he could get involved to make changes to reduce excessive alcohol consumption in his community (Box^5,15-21).

Box

Bottom Line

Patients experiencing alcohol withdrawal can present with several layers of complexity. Failure to achieve acute stabilization may be life-threatening. After providing critical care, promptly start alcohol use disorder treatment for patients who expresses a desire to change.

The triage nurse who attempts to interview Mr. G finds him tremulous, vomiting, and sweating. She notices that he seems preoccupied with pulling at his shirt, appearing to pick at things that are not there.

HISTORY Untreated depression, other comorbidities

Mr. G’s wife says he has never been psychiatrically hospitalized or exhibited suicidal behavior. Mr. G previously received care from a psychiatrist, who diagnosed him with major depressive disorder (MDD) and prescribed an antidepressant, though his wife cannot recall which specific medication. She shares it has been “a long time” since Mr. G has taken the antidepressant and the last time he received treatment for his MDD was 5 years ago. Mr. G’s wife says her husband had once abstained from alcohol use for >6 months following one of his stints at a rehabilitation center. She is not able to share many other details about Mr. G’s previous stays at rehabilitation centers, but says he always had “a rough time.”

She says Mr. G had been drinking an average of 10 drinks each night, usually within 4 hours. He has no history of nicotine or illicit substance use and has held a corporate job for the last 18 years. Several years ago, a physician had diagnosed Mr. G with hypertension and high cholesterol, but he did not follow up for treatment. Mr. G’s wife also recalls a physician told her husband he had a fatty liver. His family history includes heart disease and cancer.

The author’s observations

The treatment team observed several elements of alcohol withdrawal and classified Mr. G as a priority patient. If the team had completed the Clinical Institute Withdrawal Assessment for Alcohol–Revised scale (CIWA-Ar) (Table 1¹), Mr. G would score ≥10. While the protocol for initiating treatment for patients experiencing alcohol withdrawal varies by institution, patients with moderate to severe scores on the CIWA-Ar when experiencing withdrawal typically are managed with pharmacotherapy to address their symptoms.¹ Given the timeline of his last drink as reported by his wife, Mr. G is on the brink of experiencing a cascade of symptoms concerning for delirium tremens (DTs).² Table 2² provides a timeline and symptoms related to alcohol withdrawal. To prevent further exacerbation of symptoms, which could lead to DTs, Mr. G’s treatment team will likely initiate a benzodiazepine, using either scheduled or symptom-driven dosing.³

Two neurotransmitters that play a role in DTs are glutamate (excitatory) and GABA (inhibitory). In a normal state, the competing actions of these neurotransmitters balance each other. Acute alcohol intake causes a shift in the excitatory and inhibitory levels, with more inhibition taking place, thus causing disequilibrium. If chronic alcohol use continues, the amount of GABA inhibition reduction is related to downregulation of receptors.^2,4 Excitation increases by way of upregulation of the N-methyl-D-aspartate receptors.^2,4,5 The goal is to achieve equilibrium of the neurotransmitters, even though the balance is different from when alcohol was not present.^2,4

If alcohol is suddenly removed following chronic use, there is unchecked glutamate excitation related to a blunted GABA state. This added increase in the excitation of glutamate leads to withdrawal symptoms.^2,4 Table 3^2,4,5 depicts the neuro­transmitter equilibrium of GABA and glutamate relative to alcohol use.

EVALUATION Bleeding gums and bruising

The treatment team admits Mr. G to the triage bay and contacts the addiction psychiatrist. The physician orders laboratory tests to assess nutritional deficits and electrolyte abnormalities. Mr. G is also placed on routine assessments with symptom-triggered therapy. An assessment reveals bleeding gums and bruises, which are believed to be a result of thrombocytopenia (low blood platelet count).

The author’s observations

Though regular clinical assessment of PEth varies, it is considered to have high sensitivity and specificity to detect alcohol use.⁶ When ethanol is present, the phospholipase D enzyme acts upon phosphatidylcholine, forming a direct biomarker, PEth, on the surface of the red blood cell.^6,7 PEth’s half-life ranges from 4.5 to 12 days,⁶ and it can be detected in blood for 3 to 4 weeks after alcohol ingestion.^6,7 A PEth value <20 ng/mL indicates light or no alcohol consumption; 20 to 199 ng/mL indicates significant consumption; and >200 ng/mL indicates heavy consumption.⁷ Since Mr. G has a history of chronic alcohol use, his PEth level is expected to be >200 ng/mL.

AST/ALT and MCV are indirect biomarkers, meaning the tests are not alcohol-specific and the role of alcohol is instead observed by the damage to the body with excessive use over time.⁷ The expected AST:ALT ratio is 2:1. This is related to 3 mechanisms. The first is a decrease in ALT usually relative to B6 deficiency in individuals with alcohol use disorder (AUD). Another mechanism is related to alcohol’s propensity to affect mitochondria, which is a source for AST. Additionally, AST is also found in higher proportions in the kidneys, heart, and muscles.⁸

An MCV <100 fL would be within the normal range (80 to 100 fL) for red blood cells. While the reasons for an enlarged red blood cell (or macrocyte) are extensive, alcohol can be a factor once other causes are excluded. Additional laboratory tests and a peripheral blood smear test can help in this investigation. Alcohol disrupts the complete maturation of red blood cells.^9,10 If the cause of the macrocyte is alcohol-related and alcohol use is terminated, those enlarged cells can resolve in an average of 3 months.⁹

Vitamin B1 levels >200 nmol/L would be within normal range (74 to 222 nmol/L). Mr. G’s chronic alcohol use would likely cause him to be vitamin B1–deficient. The deficiency is usually related to diet, malabsorption, and the cells’ impaired ability to utilize vitamin B1. A consequence of vitamin B1 deficiency is Wernicke-Korsakoff syndrome.¹¹

Due to his chronic alcohol use, Mr. G’s magnesium stores most likely would be below normal range (1.7 to 2.2 mg/dL). Acting as a diuretic, alcohol depletes magnesium and other electrolytes. The intracellular shift that occurs to balance the deficit causes the body to use its normal stores of magnesium, which leads to further magnesium depletion. Other common causes include nutritional deficiency and decreased gastrointestinal absorption.¹² The bleeding the physician suspected was a result of drinking likely occurred through direct and indirect mechanisms that affect platelets.^9,13 Platelets can show improvement 1 week after drinking cessation. Some evidence suggests the risk of seizure or DTs increases significantly with a platelet count <119,000 µL per unit of blood.¹³

TREATMENT Pharmacotherapy for alcohol use disorder

As Mr. G’s condition starts to stabilize, he discusses treatment options for AUD with his physician. At the end of the discussion, Mr. G expresses an interest in starting a medication. The doctor reviews his laboratory results and available treatment options.

[polldaddy:12041630]

The author’s observations

Of the 3 FDA-approved medications for treating AUD (disulfiram, acamprosate, and naltrexone), naltrexone has been shown to decrease heavy drinking days^5,14 and comes in oral and injectable forms. Reducing drinking is achieved by reducing the rewarding effects of alcohol^5,14 and alcohol cravings.⁵ Disulfiram often has poor adherence, and like acamprosate it may be more helpful for maintenance of abstinence. Neither topiramate nor gabapentin are FDA-approved for AUD but may be used for their affects on GABA.⁵ Gabapentin may also help patients experiencing alcohol withdrawal syndrome.^5,15 Mr. G did not have any concomitant medications or comorbid medical conditions, but these factors as well as any renal or hepatic dysfunction must be considered before initiating any medications.

OUTCOME Improved well-being

Mr. G’s treatment team initiates oral naltrexone 50 mg/d, which he tolerates well without complications. He stops drinking entirely and expresses an interest in transitioning to an injectable form of naltrexone in the future. In addition to taking medication, Mr. G wants to participate in psychotherapy. Mr. G thanks his team for the care he received in the hospital, telling them, “You all saved my life.” As he discusses his past issues with alcohol, Mr. G asks his physician how he could get involved to make changes to reduce excessive alcohol consumption in his community (Box^5,15-21).

Bottom Line

Patients experiencing alcohol withdrawal can present with several layers of complexity. Failure to achieve acute stabilization may be life-threatening. After providing critical care, promptly start alcohol use disorder treatment for patients who expresses a desire to change.

CASE A difficult withdrawal

Three days after he stops drinking alcohol, Mr. G, age 49, presents to a detoxification center with his wife, who drove him there because she was concerned about his condition. She says her husband had been drinking alcohol every night for as long as she can remember. Despite numerous admissions to rehabilitation centers, Mr. G usually would resume drinking soon after he was discharged. Three days ago, Mr. G’s wife had told him she “could not take it anymore,” so he got rid of all his alcohol and stopped drinking. Mr. G’s wife felt he was doing fine the first day, but his condition increasingly worsened the second and third days.

Complex polypharmacy in patients with bipolar disorder was associated with sociodemographic and clinical features, including older age, single status, and psychiatric comorbidities, based on data from more than 500 individuals.

Patients with bipolar disorder (BD) often receive prescriptions for multiple medications to manage a range of medical and psychiatric symptoms, but the definition of polypharmacy in these patients is inconsistent, and characteristics associated with complex polypharmacy have not been well studied, wrote Andrea Aguglia, MD, of the University of Genoa, Italy, and colleagues.

Previous studies have shown an increased risk for comorbid medical and psychiatric illnesses in BD patients, the researchers noted, and changes in prescribing trends have prompted greater use of combination therapies such as mood stabilizers with or without antipsychotics.

In a study published in Psychiatry Research, the investigators reviewed data from 556 adults with BD. Participants were aged 18 and older with a primary diagnosis of BD type I or II based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, criteria. The mean age of the participants was 49.17 years, 43.7% were male, and 34.2% were employed. A total of 327 patients (58.8%) had a medical comorbidity, and 193 (34.7%) used an illicit substance.

A total of 225 patients (40.5%) met the criteria for complex polypharmacy by taking at least 4 medications.

BD patients with complex polypharmacy were significantly more likely than those without complex polypharmacy to be single (50.7% vs. 37.8%, P = .025) and unemployed (25.3% vs. 40.2%, P < .001).

On the clinical side, complex polypharmacy in BD patients was significantly associated with a higher prevalence of both medical and psychiatric comorbidities (65.3% vs. 54.4%, P = .010; and 50.7% vs. 34.1%, P < .001, respectively). The association with medical comorbidities and complex polypharmacy in BD was unexpected, the researchers said, “as psychotropic medications should be used with cautiousness in patients suffering from medical conditions.”

BD patients with complex polypharmacy also had a significantly earlier age of onset, longer duration of illness, and increased number of hospitalizations than those without complex polypharmacy.

Rates of at least one substance including alcohol, cannabinoids, and cocaine/amphetamines were significantly higher among BD patients with complex polypharmacy, compared with those without, but no differences in heroin use were noted between the groups.

In a logistic regression analysis, single status, older age, number of hospitalizations, and the presence of psychiatric comorbidities were significantly associated with complex polypharmacy.

The study findings were limited by several factors including the focus on an inpatient population, inability to consider clinical factors such as type of mood episode and bipolar cycle, and the cross-sectional design that prevented conclusions of causality, the researchers noted.

However, the study is the first known to focus on both sociodemographic and clinical factors associated with polypharmacy in BD, and the results suggest that implementing complementary psychosocial strategies might help reduce medication use in these patients, they concluded. Data from further longitudinal studies may help guide long-term management of BD, “especially when pharmacological discontinuation is needed,” they said.

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