Long COVID

The Department of Health & Human Services has issued an advisory to help medical professionals better recognize the mental health symptoms that may come with long COVID.

The nine mental health symptoms highlighted in the advisory are fatigue; cognitive impairment, including brain fog; anxiety; depression; obsessive-compulsive disorder; sleep disorders; PTSD; psychotic disorder; and start of a substance use disorder.

The advisory noted that social factors can contribute to the mental health problems for racial and ethnic minorities; people with limited access to health care; people who already have behavioral health conditions and physical disabilities; and people who are lesbian, gay, bisexual, transgender, queer, or intersex.

“Long COVID has a range of burdensome physical symptoms and can take a toll on a person’s mental health. It can be very challenging for a person, whether they are impacted themselves, or they are a caregiver for someone who is affected,” Health and Human Services Secretary Xavier Becerra said in a statement. “This advisory helps to raise awareness, especially among primary care practitioners and clinicians who are often the ones treating patients with long COVID.”

The department says about 10% of people infected with COVID have at least one long COVID symptom. Physical symptoms include dizziness, stomach upset, heart palpitations, issues with sexual desire or capacity, loss of smell or taste, thirst, chronic coughing, chest pain, and abnormal movements. 

“We know that people living with long COVID need help today, and providers need help understanding what long COVID is and how to treat it,” Admiral Rachel Levine, MD, assistant secretary for health, said in the statement. “This advisory helps bridge that gap for the behavioral health impacts of long COVID.”

Although we continue to hear a chorus of cautions from the wise folks in the public health community, most of us and our political leaders have allowed the SARS-CoV-2 pandemic to slip quietly into the dark recesses of our been-there-done-that pile. Obviously, this failure to continue learning from our mistakes is an oversight for which we will pay dearly the next time a public health crisis requiring a coordinated effort on a national and international scale raises its ugly head.

However, there is a significant portion of the population for whom the pandemic is fresh in their minds because they are experiencing the symptoms of what they have been told is long COVID. In January 2023 the Kaiser Family Foundation reported that 15% of the U.S. population feels that at some point they have experienced the symptoms of long COVID. And 6% report that they believe they currently have long COVID.

As long ago as February of 2021, Congress gave the National Institutes of Health $1.5 billion to fund a 4-year study of the prolonged health consequence of SARS-CoV-2. Sadly, 2 years into the study we aren’t too much further along in our search for answers. The Post Acute Sequelae of SARS-CoV-2 has earned an acronym, PASC, but it continues to be little more than a laundry list of vague symptoms including shortness of breath, fatigue, fever, headaches, “brain fog,” and a variety of other neurologic problems. We seem to have slipped into the same trap we find ourselves in with conditions such as chronic Lyme disease and chronic fatigue syndrome that lack workable diagnostic criteria.

However, I have just stumbled across a study in the JAMA Network Open that hints at a partial answer. Using data collected from a prospective study of nurses, investigators based at the T.H. Chan School of Public Health at Harvard found that adherence to healthy sleep prior to infection with COVID was inversely related to PCC, or Post COVID Condition, their chosen acronym for long COVID.

After taking into account a long list of covariants, the investigators found that women with consistently healthy sleep before and after their infection had the lowest risk of PCC when compared with women with consistently unhealthy sleep.

This finding seems to be telling us is that we shouldn’t be surprised to learn that folks who were relatively less healthy prior to contracting COVID are more likely to report feeling unhealthy after the acute phase of the illness has passed. It is unclear whether this observation is because their suboptimal health prior to the infection made them more vulnerable to its aftereffects or whether this is a return to their baseline for which we have labeled long COVID.

The results of this study are particularly important because it highlights our continued failure to acknowledge the critical role of sleep in the entire wellness picture. The broader message is of equal importance and that is when we are trying to discover what is making our patients sick, we must adhere to our traditional practice of taking a good and thorough history. When a patient asks the surgeon whether he will be able to play the violin after surgery, the prudent physician will always ask whether the patient has ever played the instrument.

As with any good study, it leaves more questions than it answers. While this study addresses the vague and neurologically based symptoms of long COVID, many of which are known symptoms associated with sleep deprivation, it doesn’t address the patients with more organically based symptoms such as those who have pulmonary or renal damage acquired during the acute phase of the illness. Many of these unfortunate individuals may have entered the pandemic with already damaged or vulnerable organ systems.

Finally, it leaves a very interesting question unanswered: Can we help the long COVID patients suffering with primarily neurologic symptoms by aggressively managing their preexisting unhealthy sleep habits? Or, has the damage already been done? I suspect and certainly hope it is the former.

Patients with persistent depressive or cognitive symptoms after mild to moderate COVID-19 (COVID-DC) may have gliosis and inflammation, data suggest.

In a case-control study of 40 patients who were treated at a tertiary care psychiatric hospital in Canada, the level of translocator protein total distribution volume (TSPO VT), a marker of gliosis, was 9.23 mL/cm³ among patients with COVID-DC and 7.72 mL/cm³ among control persons. Differences were particularly notable in the ventral striatum and dorsal putamen.

“Most theories assume there is inflammation in the brain [with] long COVID,” but that assumption had not been studied, author Jeffrey H. Meyer, MD, PhD, Canada Research Chair in Neurochemistry of Major Depressive Disorder at the University of Toronto, said in an interview. “Such information is pivotal to developing treatments.”

The study was published online in JAMA Psychiatry.
 

Quantifiable marker

The investigators sought to determine whether levels of TSPO VT, which are quantifiable with PET, are elevated in the dorsal putamen, ventral striatum, prefrontal cortex, anterior cingulate cortex, and hippocampus of patients with COVID-DC, compared with patients without this syndrome. These brain regions were chosen, according to the authors, “because injury in these regions, which can cause gliosis, also induces symptoms of COVID-DC.”

The study was conducted from April 2021 through June 30, 2022. The investigators compared levels of TSPO VT in the selected brain regions of 20 participants with COVID-DC (mean age, 32.7 years; 60% women) with that of 20 control persons (mean age, 33.3 years; 55% women). TSPO VT was measured with fluorine F18–labeled N-(2-(2-fluoroethoxy)benzyl)-N-(4-phenoxypyridin-3-yl)acetamide PET.

The difference in TSPO VT was most noticeable in the ventral striatum (mean difference, 1.97 mL/cm³) and dorsal putamen (mean difference, 1.70 mL/cm³). The study authors suggest that gliosis in these areas may explain some of the persistent symptoms reported in structured clinical interviews and assessed on neuropsychological and psychological testing.

For patients with COVID-DC, motor speed on the finger-tapping test was negatively associated with dorsal putamen TSPO VT (r, −0.53). The 10 participants with COVID-DC whose speed was lowest had higher mean dorsal putamen TSPO VT levels than those of control persons by 2.3 mL/cm³.

The investigators could not assess a possible association between the ventral striatum TSPO VT and anhedonia because all participants had these symptoms. No significant correlations were found between depression and TSPO VT in the prefrontal cortex or anterior cingulate cortex.

The authors acknowledged that the study was cross-sectional, and so the duration of persistently elevated TSPO VT is not yet known. In addition, elevation in TSPO VT is not completely specific to glial cells, and although correlations with finger-tapping test performance reflect associations between brain changes and symptoms, they do not prove cause and effect.

“Presently, clinicians can use treatments for symptoms in other illnesses that are [also] common with long COVID. We need better than this,” said Dr. Meyer. “Clients with long COVID should be able to state their symptoms, and the practitioner should have an evidence-based matching treatment to recommend.”

Research is ongoing. “We are acquiring more information regarding different types of inflammation in the brain, whether there is ongoing injury, and whether treatments that influence inflammation are helpful,” said Dr. Meyer.
 

Jigsaw puzzle

“While this is an important piece in the jigsaw puzzle of neuroinflammation in chronic neurological disease, it is important to keep in mind that we still lack understanding of the complex picture for several reasons,” Alexander Gerhard, MD, honorary senior lecturer in neuroscience at the University of Manchester, England, wrote in an accompanying editorial.

Among these reasons is that the PET technique used in the study is noisy and not restricted to glial cells, he wrote. TSPO expression is only one part of the brain’s neuroinflammatory response, but PET techniques “do not currently allow us to distinguish between different states of microglial activation.” In addition, “a much more detailed understanding of microglial activation at different time points” is needed before neuroinflammatory changes can be targeted therapeutically, Dr. Gerhard wrote.

In a comment, Vilma Gabbay, MD, professor of psychiatry and neuroscience and director of biomarkers and dimensional psychiatry in the Psychiatry Research Institute at Montefiore Einstein, Albert Einstein College of Medicine, New York, said that “this is an important initial step to better understand the neuropsychiatric consequences of COVID even in only a mild and moderate viral illness.” TSPO imaging through PET scanning has been used as an index for neuroinflammation and gliosis. Researchers have used it to study neurodegenerative diseases, but as the authors noted, the ligand is not specific for gliosis.

“Follow-up large cohort studies including other measures of neuroimaging modalities assessing circuitry and neurochemistry are needed,” she said. “Similarly, studying the blood-brain barrier will also allow us to better understand how the immune reaction in the blood transitions to the brain.”

This field of research is evolving, and clinical trials are ongoing, Dr. Gabbay added. Meanwhile, clinicians should monitor for, assess, and treat neuropsychiatric symptoms and “follow the literature for new research and management recommendations.”

The study was primarily funded by a Canadian Institutes of Health Research Project grant to the authors, with some funding from the Canadian Institute for Military and Veteran Health Research. Dr. Meyer received support from their Canada Research Chair awards and received grants and support from several pharmaceutical companies outside of the submitted work. Dr. Gerhard and Dr. Gabbay disclosed no relevant financial relationships.

Millions of Americans who were infected with COVID-19 still have not fully recovered their sense of taste or smell, a new report says.

Almost 36 million people were diagnosed in 2021, and 60% of them reported accompanying losses in smell or taste, according to the study by Mass Eye and Ear, which is affiliated with Harvard Medical School, Boston. The study was published in The Laryngoscope.

Most people fully regained the senses, but about 24% didn’t get smell back completely, and more than 3% had no recovery, the researchers reported. The numbers were similar among those who lost the sense of taste, they added.

“Many people never fully recovered,” Neil Bhattacharyya, MD, professor of otolaryngology and one of the study’s authors, told Fortune, estimating that up to 6 million people still have lingering symptoms. “If you lost your sense of smell, did you get it back? There’s about a one in four chance you didn’t. That’s terrible.”

Researchers looked at the records of 30,000 adults who had COVID-19 in 2021. They reported that patients who suffered more severe cases were less likely to regain some or all their senses.

Some patients said they lost appetite because they couldn’t smell food. There’s concern, too, about losing the ability to smell gas and smoke, spoiled food, and dirty diapers.

People with symptoms should see their doctors, Dr. Bhattacharyya said. The symptoms might be caused by something other than lingering COVID-19 effects and might be treatable.

Almost 36 million people were diagnosed in 2021, and 60% of them reported accompanying losses in smell or taste, according to the study by Mass Eye and Ear, which is affiliated with Harvard Medical School, Boston. The study was published in The Laryngoscope.

Most people fully regained the senses, but about 24% didn’t get smell back completely, and more than 3% had no recovery, the researchers reported. The numbers were similar among those who lost the sense of taste, they added.

“Many people never fully recovered,” Neil Bhattacharyya, MD, professor of otolaryngology and one of the study’s authors, told Fortune, estimating that up to 6 million people still have lingering symptoms. “If you lost your sense of smell, did you get it back? There’s about a one in four chance you didn’t. That’s terrible.”

Researchers looked at the records of 30,000 adults who had COVID-19 in 2021. They reported that patients who suffered more severe cases were less likely to regain some or all their senses.

Some patients said they lost appetite because they couldn’t smell food. There’s concern, too, about losing the ability to smell gas and smoke, spoiled food, and dirty diapers.

People with symptoms should see their doctors, Dr. Bhattacharyya said. The symptoms might be caused by something other than lingering COVID-19 effects and might be treatable.

Anxiety, depression, and COVID-19 can be a bad combination for your brain – and your long-term health.

Having anxiety and depression before a COVID infection increases the risk of developing long COVID, researchers have found. 

Those with long COVID who develop anxiety and depression after an infection may have brain shrinkage in areas that regulate memory, emotion, and other functions as well as disruption of brain connectivity. 

While many questions remain about these intertwined relationships, the associations aren’t a complete surprise. Experts already know that depression and anxiety are associated with inflammation and immune dysfunction, perhaps helping to explain the link between these mental health conditions, the risk of long COVID, and the changes in the brain.

Brain changes accompanying a COVID infection have concerned researchers since earlier in the pandemic, when U.K. Biobank researchers found brain atrophy, loss of grey matter, and decline in cognition in those infected with COVID, compared with those not infected.
 

Common conditions

The ramifications of the research linking anxiety, depression, and long COVID are far-reaching. According to the Centers for Disease Control and Prevention, 12.5% of U.S. adults have regular feelings of anxiety (as well as nervousness and worry), and the latest Gallup Poll found that nearly 18% of adults currently have or are being treated for depression. 

As of May 8, 10% of infected adults in the United States have long COVID, according to the CDC, and among U.S. adults ever infected, 27% have reported long COVID. Long COVID has been defined by the CDC as symptoms such as fatigue, brain fog, and cough that persist longer than 4 weeks and by the World Health Organization as symptoms persisting for 3 months or more. 

Here’s a roundup of what the research shows about mental health and long COVID risk – along with other research finding that paying attention to health habits may reduce that risk. 
 

Pre-existing depression, anxiety, and long COVID risk

A history of mental health issues – including depression, anxiety, worry, perceived stress, and loneliness – raises the risk of long COVID if infection occurs, Harvard researchers have found.

The researchers evaluated data from three large, ongoing studies including nearly 55,000 participants to determine the effects of high levels of psychological distress before a COVID infection. 

“Our study was purely survey based,” said Siwen Wang, MD, the study’s lead author and a research fellow at Harvard School of Public Health, Boston.

At the start of the survey in April 2020, none of the participants reported a current or previous COVID infection. They answered surveys about psychological distress at the start of the study, at 6 monthly time points, then quarterly until November 2021.

Over the follow up, 3,193 people reported a positive COVID test and 43% of those, or 1,403, developed long COVID. That number may seem high, but 38% of the 55,000 were active health care workers. On the final questionnaire, they reported whether their symptoms persisted for 4 weeks or longer and thus had long COVID by the standard CDC definition.

Dr. Wang’s team then looked at the infected participants’ psychological status. Anxiety raised the risk of long COVID by 42%, depression by 32%, worry about COVID by 37%, perceived stress, 46%, and loneliness, 32%.

COVID patients with a history of depression or anxiety are also more likely than others to report trouble with cognition in the weeks after a COVID infection and to develop brain fog and long COVID, UCLA researchers found. They evaluated 766 people with a confirmed COVID infection; 36% said their thinking was affected within 4 weeks of the infection. Those with anxiety and depression were more likely to report those difficulties.
 

Long COVID, then anxiety, depression, brain changes

Even mild cases of COVID infection can lead to long COVID and brain changes in those who suffer anxiety or depression after the infection, according to Clarissa Yasuda, MD, PhD, assistant professor of neurology at the University of Campinas in Sao Paulo. She has researched long COVID’s effects on the brain, even as she is coping with being a long COVID patient.

In one of her studies, presented at the 2023 annual meeting of the American Academy of Neurology, she found brain changes in people with anxiety, depression, and COVID but not in those infected who did not have either mental health issue. She evaluated 254 people, median age 41, after about 82 days from their positive PCR test for COVID.  Everyone completed a standard questionnaire for depression (the Beck Depression Inventory) and another for anxiety (the Beck Anxiety Inventory). She further divided them into two groups – the 102 with symptoms and the 152 who had no symptoms of either depression or anxiety. 

Brain scans showed those with COVID who also had anxiety and depression had shrinkage in the limbic area of the brain (which helps process emotion and memory), while those infected who didn’t have anxiety or depression did not. The researchers then scanned the brains of 148 healthy people without COVID and found no shrinkage.

The atrophy, Dr. Yasuda said, “is not something you can see with your eyes. It was only detected with computer analysis. Visualization on an MRI is normal.”

The number of people in this study with mental health issues was surprisingly high, Dr. Yasuda said. “It was intriguing for us that we noticed many individuals have both symptoms, anxiety and depression. We were not expecting it at that proportion.”

The researchers found a pattern of change not only in brain structure but in brain communication. They found those changes by using specialized software to analyze brain networks in some of the participants. Those with anxiety and depression had widespread functional changes in each of 12 networks tested. The participants without mental health symptoms showed changes in just five networks. These changes are enough to lead to problems with thinking skills and memory, Dr. Yasuda said.
 

Explaining the links

Several ideas have been proposed to explain the link between psychological distress and long COVID risk, Dr. Wang said. “The first and most mainstream mechanism for long COVID is chronic inflammation and immune dysregulation. Several mental health conditions, such as anxiety and depression, are associated with inflammation and dysfunction and that might be the link between depression, anxiety, and long COVID.”

Another less mainstream hypothesis, she said, is that “those with long COVID have more autoantibodies and they are more likely to have blood clotting issues. These have also been found in people with anxiety, depression, or other psychological distress.”

Other researchers are looking more broadly at how COVID infections affect the brain. When German researchers evaluated the brain and other body parts of 20 patients who died from non-COVID causes but had documented COVID infections, they found that 12 had accumulations of the SARS-CoV-2 spike protein in the brain tissue as well as the skull and meninges, the membranes that line the skull and spinal cord. Healthy controls did not. 

The findings suggest the persistence of the spike protein may contribute to the long-term neurologic symptoms of long COVID and may also lead to understanding of the molecular mechanisms as well as therapies for long COVID, the researchers said in their preprint report, which has not yet been peer reviewed. 

In another recent study, researchers from Germany performed neuroimaging and neuropsychological assessments of 223 people who were not vaccinated and recovered from mild to moderate COVID infections, comparing them with 223 matched healthy controls who had the same testing. In those infected, they found alterations in the cerebral white matter but no worse cognitive function in the first year after recovering. They conclude that the infection triggers a prolonged neuroinflammatory response. 

Can the brain changes reverse? “We don’t have an answer right now, but we are working on that,” Dr. Yasuda said. For now, she speculates about the return of brain volume: “I think for most it will. But I think we need to treat the symptoms. We can’t disregard the symptoms of long COVID. People are suffering a lot, and this suffering is causing some brain damage.”
 

Lifestyle habits and risk of long COVID

Meanwhile, healthy lifestyle habits in those infected can reduce the risk of long COVID, research by Dr. Wang and colleagues found. They followed nearly 2,000 women with a positive COVID test over 19 months. Of these, 44%, or 871, developed long COVID. Compared with women who followed none of the healthy lifestyle habits evaluated, those with five to six of the habits had a 49% lower risk of long COVID.

The habits included: a healthy body mass index (18.5-24.9 kg/m²), never smoking, at least 150 minutes weekly of moderate to vigorous physical activity, moderate alcohol intake (5-15 grams a day), high diet quality, and good sleep (7-9 hours nightly).
 

Long-term solutions 

Dr. Yasuda hopes that mental health care – of those infected and those not – will be taken more seriously. In a commentary on her own long COVID experience, she wrote, in part: “I fear for the numerous survivors of COVID-19 who do not have access to medical attention for their post-COVID symptoms. ... The mental health system needs to become prepared to receive survivors with different neuropsychiatric symptoms, including anxiety and depression.”

MILAN – Rheumatic disease is not considered a significant risk factor for long COVID, according to the findings of a Dutch prospective cohort study presented at the annual European Congress of Rheumatology.

Although more patients with inflammatory rheumatic diseases (iRD) report symptoms resembling long COVID, the data suggest that many of these symptoms can be attributed to the underlying rheumatic disease. “Overall, we find the data quite reassuring,” said Laura Boekel, Amsterdam Rheumatology and Immunology Center, Amsterdam University Medical Center.

The results were also published in The Lancet Rheumatology.

The risk of developing long COVID after infection with the Omicron variant appeared to be higher in patients with iRD, with 21% meeting the criteria set by the World Health Organization, compared with 13% of healthy individuals (odds ratio, 1.58; P = .037). Fatigue and loss of fitness were the most common long COVID symptoms reported by both iRD patients and controls. However, the difference in risk decreased after accounting for factors that are significantly associated with an increased risk for long COVID, such as body mass index and the severity of the acute COVID-19 infection (adjusted OR, 1.46; P = .081). The duration of symptoms did not show a statistically significant difference.

Kim Lauper, MD, University of Geneva, who chaired the session in which Ms. Boekel reported the study, said in an interview that the data should be interpreted with caution. “The data demonstrate that rheumatic disease itself is not a risk factor for long COVID. However, patients with rheumatic diseases are at a higher risk of severe disease, which in turn increases the likelihood of long COVID. Therefore, as a population, these patients are more susceptible to long COVID overall.”

Moreover, irrespective of their previous COVID-19 infection status, iRD patients often exhibit symptoms similar to those of long COVID even without a prior COVID-19 infection. (There was no history of COVID-19 in 21% of iRD patients vs. 11% of controls.) This suggests that some of the reported long COVID symptoms may actually be clinical manifestations of the underlying rheumatic disease, thereby complicating the diagnosis of long COVID in this population. The study employed the WHO definition of long COVID, which includes persistent symptoms lasting at least 8 weeks, beginning within 3 months of a confirmed SARS-CoV-2 infection, and that cannot be attributed to an alternative diagnosis. However, the data presented in Milan indicate that the WHO definition “is not well suited for patients with iRD due to significant overlap in symptoms and features,” Ms. Boekel concluded.

The cases of Omicron COVID-19 were identified during Jan. 1–April 25, 2022, among iRD patients recruited from the Amsterdam Rheumatology and Immunology Center. The population with confirmed SARS-CoV-2 Omicron infection during this period was monitored for long COVID. The total number of patients included in the study consisted of 77 iRD patients and 23 healthy controls. When asked about the potential risk of selection bias in the survey, Ms. Boekel stated that only approximately 8% of participants declined to respond, and the nonresponders were comparable with the respondents. She concluded that “the risk of selection bias is minimal.”

In an editorial published in The Lancet Rheumatology, Leonard H. Calabrese, DO, Cleveland Clinic, provided his insights on the findings. He emphasized that, “at present, long COVID remains an important reality that significantly impacts the lives of millions of individuals, yet it remains incompletely defined. ... These limitations in defining cases should not in any way undermine the experiences of those suffering from long COVID. Instead, they should serve as a reminder that, at this stage of the pandemic, we unfortunately still lack validated classification criteria for long COVID. It is crucial to include non–SARS-CoV-2–infected controls in all studies to further enhance our understanding.”

Ms. Boekel and coauthors, as well as Dr. Lauper and Dr. Calabrese, reported no relevant financial relationships.

The risk of developing long COVID after infection with the Omicron variant appeared to be higher in patients with iRD, with 21% meeting the criteria set by the World Health Organization, compared with 13% of healthy individuals (odds ratio, 1.58; P = .037). Fatigue and loss of fitness were the most common long COVID symptoms reported by both iRD patients and controls. However, the difference in risk decreased after accounting for factors that are significantly associated with an increased risk for long COVID, such as body mass index and the severity of the acute COVID-19 infection (adjusted OR, 1.46; P = .081). The duration of symptoms did not show a statistically significant difference.

Kim Lauper, MD, University of Geneva, who chaired the session in which Ms. Boekel reported the study, said in an interview that the data should be interpreted with caution. “The data demonstrate that rheumatic disease itself is not a risk factor for long COVID. However, patients with rheumatic diseases are at a higher risk of severe disease, which in turn increases the likelihood of long COVID. Therefore, as a population, these patients are more susceptible to long COVID overall.”

Moreover, irrespective of their previous COVID-19 infection status, iRD patients often exhibit symptoms similar to those of long COVID even without a prior COVID-19 infection. (There was no history of COVID-19 in 21% of iRD patients vs. 11% of controls.) This suggests that some of the reported long COVID symptoms may actually be clinical manifestations of the underlying rheumatic disease, thereby complicating the diagnosis of long COVID in this population. The study employed the WHO definition of long COVID, which includes persistent symptoms lasting at least 8 weeks, beginning within 3 months of a confirmed SARS-CoV-2 infection, and that cannot be attributed to an alternative diagnosis. However, the data presented in Milan indicate that the WHO definition “is not well suited for patients with iRD due to significant overlap in symptoms and features,” Ms. Boekel concluded.

The cases of Omicron COVID-19 were identified during Jan. 1–April 25, 2022, among iRD patients recruited from the Amsterdam Rheumatology and Immunology Center. The population with confirmed SARS-CoV-2 Omicron infection during this period was monitored for long COVID. The total number of patients included in the study consisted of 77 iRD patients and 23 healthy controls. When asked about the potential risk of selection bias in the survey, Ms. Boekel stated that only approximately 8% of participants declined to respond, and the nonresponders were comparable with the respondents. She concluded that “the risk of selection bias is minimal.”

In an editorial published in The Lancet Rheumatology, Leonard H. Calabrese, DO, Cleveland Clinic, provided his insights on the findings. He emphasized that, “at present, long COVID remains an important reality that significantly impacts the lives of millions of individuals, yet it remains incompletely defined. ... These limitations in defining cases should not in any way undermine the experiences of those suffering from long COVID. Instead, they should serve as a reminder that, at this stage of the pandemic, we unfortunately still lack validated classification criteria for long COVID. It is crucial to include non–SARS-CoV-2–infected controls in all studies to further enhance our understanding.”

Ms. Boekel and coauthors, as well as Dr. Lauper and Dr. Calabrese, reported no relevant financial relationships.

MILAN – Rheumatic disease is not considered a significant risk factor for long COVID, according to the findings of a Dutch prospective cohort study presented at the annual European Congress of Rheumatology.

As doctors and researchers learn more about long COVID, an interesting fact has emerged: Women experiencing menopause and perimenopause appear to be more likely to experience serious complications from the virus.
 

British researchers have noted that women at midlife who have long COVID seem to get specific, and severe, symptoms, including brain fog, fatigue, new-onset dizziness, and difficulty sleeping through the night. 

Doctors also think it’s possible that long COVID worsens the symptoms of perimenopause and menopause. Lower levels of estrogen and testosterone appear to be the reason.

“A long COVID theory is that there is a temporary disruption to physiological ovarian steroid hormone production, which could [worsen] symptoms of perimenopause and menopause,” said JoAnn V. Pinkerton, MD, professor of obstetrics at the University of Virginia, Charlottesville, and executive director of the North American Menopause Society.

Long COVID symptoms and menopause symptoms can also be very hard to tell apart. 

Another U.K. study cautions that because of this kind of symptom overlap, women at midlife may be misdiagnosed. Research from the North American Menopause Society shows that many women may have trouble recovering from long COVID unless their hormone deficiency is treated. 
 

What are the symptoms of long COVID?

There are over 200 symptoms that have been associated with long COVID, according to the American Medical Association. Some common symptoms are currently defined as the following: feeling extremely tired, feeling depleted after exertion, cognitive issues such as brain fog, heart beating over 100 times a minute, and a loss of sense of smell and taste. 

Long COVID symptoms begin a few weeks to a few months after a COVID infection. They can last an indefinite amount of time, but “the hope is that long COVID will not be lifelong,” said Clare Flannery, MD, an endocrinologist and associate professor in the departments of obstetrics, gynecology and reproductive sciences and internal medicine at Yale University, New Haven, Conn. 
 

What are the symptoms of menopause?

Some symptoms of menopause include vaginal infections, irregular bleeding, urinary problems, and sexual problems.

Women in their middle years have other symptoms that can be the same as perimenopause/menopause symptoms. 

“Common symptoms of perimenopause and menopause which may also be symptoms ascribed to long COVID include hot flashes, night sweats, disrupted sleep, low mood, depression or anxiety, decreased concentration, memory problems, joint and muscle pains, and headaches,” Dr. Pinkerton said. 
 

Can long COVID actually bring on menopause? 

In short: Possibly.

A new study from the Massachusetts Institute of Technology/Patient-Led Research Collaborative/University of California, San Francisco, found that long COVID can cause disruptions to a woman’s menstrual cycle, ovaries, fertility, and menopause itself. 

This could be caused by chronic inflammation caused by long COVID on hormones as well. This kind of inflammatory response could explain irregularities in a woman’s menstrual cycle, according to the Newson Health Research and Education study. For instance, “when the body has inflammation, ovulation can happen,” Dr. Flannery said. 

The mechanism for how long COVID could spur menopause can also involve a woman’s ovaries. 

“Since the theory is that COVID affects the ovary with declines in ovarian reserve and ovarian function, it makes sense that long COVID could bring on symptoms of perimenopause or menopause more acutely or more severely and lengthen the symptoms of the perimenopause and menopausal transition,” Dr. Pinkerton said. 
 

How can hormone replacement therapy benefit women dealing with long COVID during menopause?

Estradiol, the strongest estrogen hormone in a woman’s body, has already been shown to have a positive effect against COVID.

“Estradiol therapy treats symptoms more aggressively in the setting of long COVID,” said Dr. Flannery.

Estradiol is also a form of hormone therapy for menopause symptoms. 

“Estradiol has been shown to help hot flashes, night sweats, and sleep and improve mood during perimenopause,” said Dr. Pinkerton. “So it’s likely that perimenopausal or menopausal women with long COVID would see improvements both due to the action of estradiol on the ovary seen during COVID and the improvements in symptoms.”

Estrogen-based hormone therapy has been linked to an increased risk for endometrial, breast, and ovarian cancer, according to the American Cancer Society. This means you should carefully consider how comfortable you are with those additional risks before starting this kind of therapy.

“Which of your symptoms are the most difficult to manage? You may see if you can navigate one to three of them. What are you willing to do for your symptoms? If a woman is willing to favor her sleep for the next 6 months to a year, she may be willing to change how she perceives her risk for cancer,” Dr. Flannery said. “What risk is a woman willing to take? I think if someone has a very low concern about a risk of cancer, and she’s suffering a disrupted life, then taking estradiol in a 1- to 2-year trial period could be critical to help.” 
 

What else can help ease long COVID during menopause? 

Getting the COVID vaccine, as well as getting a booster, could help. Not only will this help prevent people from being reinfected with COVID, which can worsen symptoms, but a new Swedish study says there is no evidence that it will cause postmenopausal problems like irregular bleeding.

“Weak and inconsistent associations were observed between SARS-CoV-2 vaccination and healthcare contacts for bleeding in women who are postmenopausal, and even less evidence was recorded of an association for menstrual disturbance or bleeding in women who were premenopausal,” said study coauthor Rickard Ljung, MD, PhD, MPH, professor and acting head of the pharmacoepidemiology and analysis department in the division of use and information of the Swedish Medical Products Agency in Uppsala.

The American Academy of Physical Medicine and Rehabilitation (AAPM&R) has issued new consensus guidance on the assessment and treatment of neurologic sequelae in patients with long COVID, also known as postacute sequelae of SARS-CoV-2 infection (PASC).

The new recommendations, which were published online in Physical Medicine & Rehabilitation, are the result of a collaboration between experts from a variety of medical specialties at 41 long COVID clinics across the United States.

Because physical medicine specialists treat individuals with disability and functional impairments, the AAPM&R was among the first organizations to initiate guidance for the assessment and treatment of long COVID and issued its first consensus statement that addressed long COVID–related fatigue in 2021.

Even though the number of COVID cases and hospitalizations has declined from the peak, long COVID continues to be a major public health issue, Steven R. Flanagan, MD, AAPM&R president-elect and Howard A. Rusk Professor of Rehabilitation Medicine at NYU Langone Health, New York, told reporters attending a press briefing.

“There is some evidence that some of the antivirals may actually help reduce the incidence but not everybody gets them,” said Dr. Flanagan. “In our own clinic here, we continue to see many, many people with problems associated with long COVID,” he added.

According to the consensus guidelines, about 80% of patients hospitalized with acute COVID-19 have neurological symptoms. But these symptoms are not just limited to people who had severe illness, said Leslie Rydberg, MD, coauthor of the neurology long COVID guidance statement.

“What we know is that many people with mild or moderate COVID infection end up with neurologic sequelae that last longer than 4 weeks,” said Dr. Rydberg, the Henry and Monika Betts Medical Student Education Chair and assistant residency program director at Shirley Ryan AbilityLab, Chicago.

Dr. Rydberg added that patients who have symptoms for longer than a month after the initial infection should be evaluated. Although the definition of what constitutes PASC is evolving, the guidance states that the literature indicates that it should be defined as the persistence of symptoms 4 weeks beyond the initial infection.

The most common neurological symptoms are headache, weakness, muscular pain, nerve pain, tremors, peripheral nerve issues, sleep issues, and cognitive effects, Dr. Rydberg told reporters.

She added that “identifying patients with progressive or ominous ‘red flag’ neurological symptoms is essential for emergent triaging.”

Among the red flags are sudden or progressive weakness or sudden or progressive sensory changes, because those could indicate an acute neurologic condition – either due to long COVID or other illnesses – such as a stroke or a problem with the spinal cord, Guillain-Barré syndrome, or myopathy.

While those signs and symptoms would likely be flagged by most clinicians, some of the emergent or urgent signs – such as upper motor neuron changes on physical exam – are more subtle, said Dr. Rydberg.

The new guidance spells out steps for initial evaluation, including identification of red flag symptoms, and also provides treatment recommendations.

Experts also recommend clinicians do the following:

• Treat underlying medical conditions such as pain, psychiatric, cardiovascular, respiratory, and other conditions that may be contributing to neurologic symptoms.
• Consider polypharmacy reduction, looking especially closely at medications with a known impact on neurologic symptoms.
• Urge patients to get regular physical activity, as tolerated, while avoiding overuse syndrome.
• Work with physical, occupational, and speech therapists to increase function and independence.
• Refer patients to counseling and community resources for risk factor modification.

The treatment recommendations are more in-depth for specific long-COVID conditions including headache, cranial neuropathies, sleep disturbances, and neuropathies.

The guidance includes a special statement on the importance of ensuring equitable access to care. Underserved, marginalized, and socioeconomically disadvantaged communities had notably higher rates of infection, hospitalization, and death with less access to rehabilitation services before the pandemic, said Monica Verduzco-Gutierrez, MD, chair of the department of rehabilitation medicine at Long School of Medicine, UT Health San Antonio, and a guideline coauthor.

“We know that these communities have been historically underserved, that there’s already access issues, and that they’re disproportionately impacted by the pandemic,” said Dr. Verduzco-Gutierrez. “This continues as patients develop PASC, or long COVID,” she said, adding that these individuals are still less likely to receive rehabilitation services. “This can lead to poorer outcomes and widened disparities.”

The AAPM&R PASC Multi-Disciplinary Collaborative has previously issued consensus guidance on fatigue, breathing discomfort and respiratory distress, cognitive symptoms, cardiovascular complications, pediatrics, and autonomic dysfunction, and will be publishing guidance on mental health soon.

The collaborative is also putting together a compilation of all the guidance – “a ‘greatest hits’ if you like,” said Dr. Verduzco-Gutierrez.

For clinicians who are unaccustomed to caring for patients with long COVID, the hope is that this new guidance will help them manage the condition, Dr. Rydberg said.

The guidance was written with the support of the AAPM&R. Dr. Verduzco-Gutierrez and two coauthors have disclosed grants, contracts, or honoraria from various funding sources, some paid to their institutions and some personal reimbursement for activities related to PASC and broader areas of research and expertise. However, none of the authors have any conflicts relative to the work on the guidance.

The American Academy of Physical Medicine and Rehabilitation (AAPM&R) has issued new consensus guidance on the assessment and treatment of neurologic sequelae in patients with long COVID, also known as postacute sequelae of SARS-CoV-2 infection (PASC).

The new recommendations, which were published online in Physical Medicine & Rehabilitation, are the result of a collaboration between experts from a variety of medical specialties at 41 long COVID clinics across the United States.

Because physical medicine specialists treat individuals with disability and functional impairments, the AAPM&R was among the first organizations to initiate guidance for the assessment and treatment of long COVID and issued its first consensus statement that addressed long COVID–related fatigue in 2021.

Even though the number of COVID cases and hospitalizations has declined from the peak, long COVID continues to be a major public health issue, Steven R. Flanagan, MD, AAPM&R president-elect and Howard A. Rusk Professor of Rehabilitation Medicine at NYU Langone Health, New York, told reporters attending a press briefing.

“There is some evidence that some of the antivirals may actually help reduce the incidence but not everybody gets them,” said Dr. Flanagan. “In our own clinic here, we continue to see many, many people with problems associated with long COVID,” he added.

According to the consensus guidelines, about 80% of patients hospitalized with acute COVID-19 have neurological symptoms. But these symptoms are not just limited to people who had severe illness, said Leslie Rydberg, MD, coauthor of the neurology long COVID guidance statement.

“What we know is that many people with mild or moderate COVID infection end up with neurologic sequelae that last longer than 4 weeks,” said Dr. Rydberg, the Henry and Monika Betts Medical Student Education Chair and assistant residency program director at Shirley Ryan AbilityLab, Chicago.

Dr. Rydberg added that patients who have symptoms for longer than a month after the initial infection should be evaluated. Although the definition of what constitutes PASC is evolving, the guidance states that the literature indicates that it should be defined as the persistence of symptoms 4 weeks beyond the initial infection.

The most common neurological symptoms are headache, weakness, muscular pain, nerve pain, tremors, peripheral nerve issues, sleep issues, and cognitive effects, Dr. Rydberg told reporters.

She added that “identifying patients with progressive or ominous ‘red flag’ neurological symptoms is essential for emergent triaging.”

Among the red flags are sudden or progressive weakness or sudden or progressive sensory changes, because those could indicate an acute neurologic condition – either due to long COVID or other illnesses – such as a stroke or a problem with the spinal cord, Guillain-Barré syndrome, or myopathy.

While those signs and symptoms would likely be flagged by most clinicians, some of the emergent or urgent signs – such as upper motor neuron changes on physical exam – are more subtle, said Dr. Rydberg.

The new guidance spells out steps for initial evaluation, including identification of red flag symptoms, and also provides treatment recommendations.

Experts also recommend clinicians do the following:

• Treat underlying medical conditions such as pain, psychiatric, cardiovascular, respiratory, and other conditions that may be contributing to neurologic symptoms.
• Consider polypharmacy reduction, looking especially closely at medications with a known impact on neurologic symptoms.
• Urge patients to get regular physical activity, as tolerated, while avoiding overuse syndrome.
• Work with physical, occupational, and speech therapists to increase function and independence.
• Refer patients to counseling and community resources for risk factor modification.

The treatment recommendations are more in-depth for specific long-COVID conditions including headache, cranial neuropathies, sleep disturbances, and neuropathies.

The guidance includes a special statement on the importance of ensuring equitable access to care. Underserved, marginalized, and socioeconomically disadvantaged communities had notably higher rates of infection, hospitalization, and death with less access to rehabilitation services before the pandemic, said Monica Verduzco-Gutierrez, MD, chair of the department of rehabilitation medicine at Long School of Medicine, UT Health San Antonio, and a guideline coauthor.

“We know that these communities have been historically underserved, that there’s already access issues, and that they’re disproportionately impacted by the pandemic,” said Dr. Verduzco-Gutierrez. “This continues as patients develop PASC, or long COVID,” she said, adding that these individuals are still less likely to receive rehabilitation services. “This can lead to poorer outcomes and widened disparities.”

The AAPM&R PASC Multi-Disciplinary Collaborative has previously issued consensus guidance on fatigue, breathing discomfort and respiratory distress, cognitive symptoms, cardiovascular complications, pediatrics, and autonomic dysfunction, and will be publishing guidance on mental health soon.

The collaborative is also putting together a compilation of all the guidance – “a ‘greatest hits’ if you like,” said Dr. Verduzco-Gutierrez.

For clinicians who are unaccustomed to caring for patients with long COVID, the hope is that this new guidance will help them manage the condition, Dr. Rydberg said.

The guidance was written with the support of the AAPM&R. Dr. Verduzco-Gutierrez and two coauthors have disclosed grants, contracts, or honoraria from various funding sources, some paid to their institutions and some personal reimbursement for activities related to PASC and broader areas of research and expertise. However, none of the authors have any conflicts relative to the work on the guidance.

Patients with long COVID-19 – where the effects of an initial COVID infection last more than 12 weeks – had lower levels of 25(OH) vitamin D than other patients who survived COVID-19, in a retrospective, case-matched study.

The lower levels of vitamin D in patients with long COVID were most notable in those with brain fog.

Reasonable to test vitamin D levels, consider supplementation

Invited to comment, Amiel Dror, MD, PhD, who led a related study that showed that people with a vitamin D deficiency were more likely to have severe COVID-19, agreed.

“The novelty and significance of this [new] study lie in the fact that it expands on our current understanding of the interplay between vitamin D and COVID-19, taking it beyond the acute phase of the disease,” said Dr. Dror, from Bar-Ilan University, Safed, Israel.

“It’s striking to see how vitamin D levels continue to influence patients’ health even after recovery from the initial infection,” he noted. 

“The findings certainly add weight to the argument for conducting a randomized control trial [RCT],” he continued, which “would enable us to conclusively determine whether vitamin D supplementation can effectively reduce the risk or severity of long COVID.”

“In the interim,” Dr. Dror said, “given the safety profile of vitamin D and its broad health benefits, it could be reasonable to test for vitamin D levels in patients admitted with COVID-19. If levels are found to be low, supplementation could be considered.”

“However, it’s important to note that this should be done under medical supervision,” he cautioned, “and further studies are needed to establish the optimal timing and dosage of supplementation.”

“I anticipate that we’ll see more RCTs [of this] in the future,” he speculated.
 

Low vitamin D and risk of long COVID

Long COVID is an emerging syndrome that affects 50%-70% of COVID-19 survivors.

Low levels of vitamin D have been associated with increased likelihood of needing mechanical ventilation and worse survival in patients hospitalized with COVID-19, but the risk of long COVID associated with vitamin D has not been known.

Researchers analyzed data from adults aged 18 and older hospitalized at San Raffaele Hospital with a confirmed diagnosis of COVID-19 and discharged during the first pandemic wave, from March to May 2020, and then seen 6-months later for follow-up.

Patients were excluded if they had been admitted to the intensive care unit during hospitalization or had missing medical data or blood samples available to determine (OH) vitamin D levels, at admission and the 6-month follow-up.

Long COVID-19 was defined based on the U.K. National Institute for Health and Care Excellence guidelines as the concomitant presence of at least two or more of 17 signs and symptoms that were absent prior to the COVID-19 infection and could only be attributed to that acute disease.

Researchers identified 50 patients with long COVID at the 6-month follow-up and matched them with 50 patients without long COVID at that time point, based on age, sex, concomitant comorbidities, need for noninvasive mechanical ventilation, and week of evaluation.

Patients were a mean age of 61 years (range, 51-73) and 56% were men; 28% had been on a ventilator during hospitalization for COVID-19.

The most frequent signs and symptoms at 6 months in the patients with long COVID were asthenia (weakness, 38% of patients), dysgeusia (bad taste in the mouth, 34%), dyspnea (shortness of breath, 34%), and anosmia (loss of sense of smell, 24%).

Most symptoms were related to the cardiorespiratory system (42%), the feeling of well-being (42%), or the senses (36%), and fewer patients had symptoms related to neurocognitive impairment (headache or brain fog, 14%), or ear, nose, and throat (12%), or gastrointestinal system (4%).

Patients with long COVID had lower mean 25(OH) vitamin D levels than patients without long COVID (20.1 vs 23.2 ng/mL; P = .03). However, actual vitamin D deficiency levels were similar in both groups.

Two-thirds of patients with low vitamin D levels at hospital admission still presented with low levels at the 6-month follow-up.

Vitamin D levels were significantly lower in patients with neurocognitive symptoms at follow-up (n = 7) than in those without such symptoms (n = 93) (14.6 vs. 20.6 ng/mL; P = .042).

In patients with vitamin D deficiency (< 20 ng/mL) at admission and at follow-up (n = 42), those with long COVID (n = 22) had lower vitamin D levels at follow-up than those without long COVID (n = 20) (12.7 vs. 15.2 ng/mL; P = .041).

And in multiple regression analyses, a lower 25(OH) vitamin D level at follow-up was the only variable that was significantly associated with long COVID (odds ratio, 1.09; 95% confidence interval, 1.01-1.16; P = .008).

The findings “strongly reinforce the clinical usefulness of 25(OH) vitamin D evaluation as a possible modifiable pathophysiological factor underlying this emerging worldwide critical health issue,” the researchers concluded.

The study was supported by Abiogen Pharma. One study author is an employee at Abiogen. Dr. Giustina has reported being a consultant for Abiogen and Takeda and receiving a research grant to his institution from Takeda. Dr. Di Filippo and the other authors reported no relevant financial relationships.

Hyperbaric oxygen therapy (HBOT) increased markers of heart function in a small randomized, controlled trial of patients with long COVID.

Patients with reduced left ventricular global longitudinal strain (GLS) at baseline who received HBOT had a significant increase in GLS, compared with those who received sham treatment.

GLS is a measure of systolic function that is thought to be a predictor of heart failure–related outcomes.

The study also showed that global work efficiency (GWE) and the global work index (GWI) increased in HBOT-treated patients, though not significantly.

“HBOT is an effective treatment for diabetic foot ulcers, decompression sickness in divers, and other conditions, such as cognitive impairment after stroke,” Marina Leitman, MD, of the Sackler School of Medicine, Tel Aviv, said in an interview. Her team also studied HBOT in asymptomatic older patients and found that the treatment seemed to improve left ventricular end systolic function.

“We should open our minds to thinking about this treatment for another indication,” she said. “That is the basis of precision medicine. We have this treatment and know it can be effective for cardiac pathology.

“Now we can say that post-COVID syndrome patients probably should be evaluated with echocardiography and GLS, which is the main parameter that showed improvement in our study,” she added. “If GLS is below normal values, these patients can benefit from HBOT, although additional research is needed to determine the optimal number of sessions.”

Dr. Leitman presented the study at the European Association of Cardiovascular Imaging 2023, a scientific congress of the European Society of Cardiology.
 

Biomarker changes

The study enrolled 60 hospitalized and nonhospitalized post-COVID syndrome patients with ongoing symptoms for at least 3 months after having mild to moderate symptomatic COVID-19.

Participants were randomized to receive HBOT or a sham procedure five times per week for 8 weeks, for a total of 40 sessions. They underwent echocardiography at baseline and 1-3 weeks after the final session to assess GLS.

The HBOT group received 100% oxygen through a mask at a pressure of two atmospheres for 90 minutes, with 5-minute air breaks every 20 minutes.

The sham group received 21% oxygen by mask at one atmosphere for 90 minutes.

At baseline, 29 participants (48%) had reduced GLS, despite having a normal ejection fraction, Dr. Leitman said. Of those, 16 (53%) were in the HBOT group and 13 (43%) were in the sham group.

The average GLS at baseline across all participants was –17.8%; a normal value is about –20%.

In the HBOT group, GLS increased significantly from –17.8% at baseline to –20.2% after HBOT. In the sham group, GLS was –17.8% at baseline and –19.1% at the end of the study, with no statistically significant difference between the two measurements.

In addition, GWE increased overall after HBOT from 96.3 to 97.1.

Dr. Leitman’s poster showed GLS and myocardial work indices before and after HBOT in a 45-year-old patient. Prior to treatment, GLS was –19%; GWE was 96%; and GWI was 1,833 mm Hg.

After HBOT treatment, GLS was –22%; GWE, 98%; and GWI, 1,911 mm Hg.
 

Clinical relevance unclear

Scott Gorenstein, MD, associate professor in the department of surgery and medical director of wound care and hyperbaric medicine at NYU Langone–Long Island, New York, commented on the study for this news organization.

“The approach certainly warrants studying, but the benefit is difficult to assess,” he said. “We still don’t understand the mechanism of long COVID, so it’s difficult to go from there to say that HBOT will be an effective therapy.”

That said, he added, “This is probably the best study I’ve seen in that it’s a randomized controlled trial, rather than a case series.”

Nevertheless, he noted, “We have no idea from this study whether the change in GLS is clinically relevant. As a clinician, I can’t now say that HBOT is going to improve heart failure secondary to long COVID. We don’t know whether the participants were New York heart failure class 3 or 4, for example, and all of a sudden went from really sick to really good.”

“There are many interventions that may change markers of cardiac function or inflammation,” he said. “But if they don’t make a difference in quantity or quality of life, is the treatment really valuable?”

Dr. Gorenstein said he would have no problem treating a patient with mild to moderate COVID-related heart failure with HBOT, since his own team’s study conducted near the outset of the pandemic showed it was safe. “But HBOT is an expensive treatment in the U.S. and there still are some risks and side effects, albeit very, very low.”

The study received no funding. Dr. Leitman and Dr. Gorenstein have disclosed no relevant financial relationships.

At baseline, 29 participants (48%) had reduced GLS, despite having a normal ejection fraction, Dr. Leitman said. Of those, 16 (53%) were in the HBOT group and 13 (43%) were in the sham group.

The average GLS at baseline across all participants was –17.8%; a normal value is about –20%.

In the HBOT group, GLS increased significantly from –17.8% at baseline to –20.2% after HBOT. In the sham group, GLS was –17.8% at baseline and –19.1% at the end of the study, with no statistically significant difference between the two measurements.

In addition, GWE increased overall after HBOT from 96.3 to 97.1.

Dr. Leitman’s poster showed GLS and myocardial work indices before and after HBOT in a 45-year-old patient. Prior to treatment, GLS was –19%; GWE was 96%; and GWI was 1,833 mm Hg.

After HBOT treatment, GLS was –22%; GWE, 98%; and GWI, 1,911 mm Hg.
 

Clinical relevance unclear

Scott Gorenstein, MD, associate professor in the department of surgery and medical director of wound care and hyperbaric medicine at NYU Langone–Long Island, New York, commented on the study for this news organization.

“The approach certainly warrants studying, but the benefit is difficult to assess,” he said. “We still don’t understand the mechanism of long COVID, so it’s difficult to go from there to say that HBOT will be an effective therapy.”

That said, he added, “This is probably the best study I’ve seen in that it’s a randomized controlled trial, rather than a case series.”

Nevertheless, he noted, “We have no idea from this study whether the change in GLS is clinically relevant. As a clinician, I can’t now say that HBOT is going to improve heart failure secondary to long COVID. We don’t know whether the participants were New York heart failure class 3 or 4, for example, and all of a sudden went from really sick to really good.”

“There are many interventions that may change markers of cardiac function or inflammation,” he said. “But if they don’t make a difference in quantity or quality of life, is the treatment really valuable?”

Dr. Gorenstein said he would have no problem treating a patient with mild to moderate COVID-related heart failure with HBOT, since his own team’s study conducted near the outset of the pandemic showed it was safe. “But HBOT is an expensive treatment in the U.S. and there still are some risks and side effects, albeit very, very low.”

The study received no funding. Dr. Leitman and Dr. Gorenstein have disclosed no relevant financial relationships.
