Long COVID

People with long COVID have specific biomarkers in their blood, according to results of a study published in Nature. 

The findings may be a step toward creating blood tests to positively identify people with long COVID so specialized treatments can be employed, researchers said.

 “This is a decisive step forward in the development of valid and reliable blood testing protocols for long COVID,” said David Putrino, PhD., lead author and professor of rehabilitation and human performance and director of the Abilities Research Center at Icahn Mount Sinai Health System, New York.

Researchers from the Icahn School of Medicine at Mount Sinai and Yale School of Medicine looked at blood samples from about 270 people between January 2021 and June 2022. The people had never been infected with COVID, had fully recovered from an infection, or still showed symptoms at least four months after infection.

Using machine learning, the research teams were able to differentiate between people with and without long COVID with 96% accuracy based on distinctive features in the blood samples, according to a news release from Mount Sinai.

People with long COVID had abnormal T-cell activity and low levels of the hormone cortisol. Cortisol helps people feel alert and awake, which would explain why people with long COVID often report fatigue, NBC News said in a report on the study.

“It was one of the findings that most definitively separated the folks with long Covid from the people without long Covid,” Dr. Putrino told NBC News.

The study also found that long COVID appears to reactivate latent viruses including Epstein-Barr and mononucleosis, the study said.

The blood tests could allow doctors to come up with specialized treatments in people who report a wide variety of long COVID symptoms, Dr. Putrino said. 

“There is no ‘silver bullet’ for treating long COVID, because it is an illness that infiltrates complex systems such as the immune and hormonal regulation,” he said.

The Centers for Disease Control and Prevention says about one in five Americans who had COVID still have long COVID. Symptoms include fatigue, brain fog, dizziness, digestive problems, and loss of smell and taste.

Taking creatine as a supplement for 6 months appears to significantly improve clinical features of post–COVID-19 fatigue syndrome (PVFS or long COVID), a small randomized, placebo-controlled, double-blinded study suggests.

Researchers, led by Jelena Slankamenac, with Applied Bioenergetics Lab, Faculty of Sport and PE, University of Novi Sad, Serbia, published their findings in Food, Science & Nutrition .

“This is the first human study known to the authors that evaluated the efficacy and safety of supplemental creatine for fatigue, tissue bioenergetics, and patient-reported outcomes in patients with post–COVID-19 fatigue syndrome,” the authors write.

They say the findings may be attributed to creatine’s “energy-replenishing and neuroprotective activity.”
 

Significant reductions in symptoms

Researchers randomized the 12 participants into two groups of 6 each. The creatine group received 4 g creatine monohydrate per day, while the placebo group received the same amount of inulin.

At 3 months, dietary creatine supplements produced a significant reduction in fatigue, compared with baseline values ( P = .04) and significantly improved scores for several long COVID–related symptoms, including loss of taste, breathing difficulties, body aches, headache, and difficulties concentrating) ( P < .05), the researchers report.

Intervention effect sizes were assessed by Cohen statistics, with a d of at least 0.8 indicating a large effect.

Among highlights of the results were that patients reported a significant 77.8% drop in scores for concentration difficulties at the 3-month follow-up (Cohen’s effect, d = 1.19) and no concentration difficulties at the 6-month follow-up (Cohen’s effect, d = 2.46).

Total creatine levels increased in several locations across the brain (as much as 33% for right parietal white matter). No changes in tissue creatine levels were found in the placebo group during the trial.

“Since PVFS is characterized by impaired tissue bioenergetics ..., supplemental creatine might be an effective dietary intervention to uphold brain creatine in post–COVID-19 fatigue syndrome,” the authors write.

The authors add that creatine supplements for long COVID patients could benefit organs beyond the brain as participants saw “a significant drop in lung and body pain after the intervention.”
 

Unanswered questions

Some experts said the results should be interpreted with caution.

“This research paper is very interesting,” says Nisha Viswanathan, MD, director of the long COVID program at University of California, Los Angeles, “but the limited number of patients makes the results difficult to generalize.”

Dr. Viswanathan, who was not part of the study, pointed out that the patients included in this study had a recent COVID infection (under 3 months).

“Acute COVID infection can take up to 3 months to resolve,” she says. “We define patients with long COVID as those with symptoms lasting greater than 3 months. Therefore, these patients could have had improvements in their fatigue due to the natural course of the illness rather than creatine supplementation.”

Alba Azola, MD, assistant professor in the department of physical medicine and rehabilitation at Johns Hopkins University, Baltimore, said she also was troubled by the window of 3 months for recent COVID infection.

She said she would like to see results for patients who have ongoing symptoms for at least 6 months after infection, especially given creatine supplements’ history in research.

Creatine supplements for other conditions, such as fibromyalgia and chronic fatigue syndrome, have been tested for nearly 2 decades, she pointed out, with conflicting findings, something the authors acknowledge in the paper.

“I think it’s premature to say (creatine) is the key,” she says. She added that the small sample size is important to consider given the heterogeneity of patients with long COVID.

That said, Dr. Azola says, she applauds all efforts to find treatments for long COVID, especially randomized, controlled studies like this one.
 

No major side effects

No major side effects were reported for either intervention, except for transient mild nausea reported by one patient after taking creatine.

Compliance with the intervention was 90.6% ± 3.5% in the creatine group and 95.3% ± 5.0% in the control group (P = .04).

Participants were eligible for inclusion if they were 18-65 years old, had a positive COVID test within the last 3 months (documented by a valid polymerase chain reaction [PCR] or antigen test performed in a COVID-19–certified lab); had moderate to severe fatigue; and at least one additional COVID-related symptom, including loss of taste or smell, breathing trouble, lung pain, body aches, headaches, or difficulties concentrating.

The authors acknowledge that they selected a sample of young to middle-aged adults experiencing moderate long COVID symptoms, and it’s unknown whether creatine is equally effective in other PVFS populations, such as elderly people, children, or patients with less or more severe disease.

Crippling symptoms, lost careers, and eroded incomes: This is the harsh reality for doctors suffering with long COVID, according to the first major survey of physicians with the condition.

The survey, conducted by the British Medical Association and the Long COVID Doctors for Action support group, sheds light on the lingering effects of long COVID on more than 600 chronically ill and disabled doctors with the condition. It also spotlights what they describe as a lack of medical and financial support from their government and employers at the National Health Service.

“We feel betrayed and abandoned,” said Kelly Fearnley, MBChB, chair and cofounder of Long COVID Doctors for Action. “At a time of national crisis, when health care workers were asked to step up, we did. When the nation needed us, we stepped up. We put our lives on the line. We put our families’ lives on the line. And now that we are injured after knowingly being unprotected and deliberately and repeatedly exposed to a level 3 biohazard, we now find ourselves in this position.”

Dr. Fearnley fell ill while working in a hospital’s COVID ward in November 2020. She is one of an estimated 2 million people in the United Kingdom – including thousands of NHS employees – with long COVID. She hasn’t been able to return to work in nearly 3 years.

Long COVID affects more than 65 million people worldwide. It is estimated that 1 in 10 people infected with the virus develop long-term symptoms. In the United Kingdom, health care and social care workers are seven times more likely to have had severe COVID-19 than other types of employees.

Doctors responding to the BMA survey reported a wide range of long COVID symptoms, including fatigue, headaches, muscular pain, nerve damage, joint pain, and respiratory problems.

Among the survey’s key findings, 60% of doctors said long COVID has affected their ability to carry out day-to-day tasks on a regular basis. Almost one in five (18%) said they were no longer able to work, while fewer than one in three (31%) were working full time. This compares with more than half (57%) of respondents working full time before the onset of their COVID illness – a decline of 46%.

Nearly half (48%) of respondents said they have experienced some form of loss of earnings as a result of long COVID, and almost half of the doctors were never referred to an NHS long COVID clinic. The survey included the following first-person accounts from doctors living with the condition.

• One doctor said: “I nearly lost my life, my home, my partner and my career. I have received little support to help keep these. The impact on my mental health nearly cost [me] my life again.”
• A senior consulting physician commented: “Life is absolutely miserable. Every day is a struggle. I wake up exhausted, the insomnia and night terrors are horrendous as I live through my worst fears every night. Any activity such as eating meals, washing, etc., will mean I have to go to bed for a few hours. I am unable to look after myself or my child, exercise or maintain social relationships. I have no financial security. Long COVID has totally destroyed my life.”
• A salaried general practitioner said: “I can no longer work, finances are ruined. I didn’t have employment protection so am now unemployed and penniless.”

Calls for action from the BMA include the following:

• Financial support for doctors and health care staff with long COVID.
• The recognition of long COVID as an occupational disease among health care workers, along with a definition of the condition that covers all of the debilitating disease’s symptoms.
• Improved access to physical and mental health services to help comprehensive assessment, investigations, and treatment.
• Greater workplace protection for health care staff who risk their lives for others.
• Better support for long COVID sufferers to return to work safely if they can, including a flexible approach to the use of workplace adjustments.

“One would think, given the circumstances under which we fell ill and current workforce shortages, NHS employers would be eager to do everything to facilitate the return to work of people with long COVID,” said Dr. Fearnley. “However, NHS employers are legally required to implement only ‘reasonable adjustments,’ and so things such as extended phased return or adjustments to shift patterns are not always being facilitated. Instead, an increasing number of employers are choosing to terminate contracts.”

Raymond Agius, the BMA’s occupational medicine committee cochair, also put the blame on inadequate safety measures for doctors. Those inadequate measures persist to this day, inasmuch as U.K. hospitals have dropped masking requirements.

“During the COVID-19 pandemic, doctors were left exposed and unprotected at work,” he said in a BMA press release. “They often did not have access to the right PPE. ... Too many risk assessments of workplaces and especially of vulnerable doctors were not undertaken.”

A small minority of doctors who were surveyed said they had access to respiratory protective equipment about the time they contracted COVID-19. Only 11% had access to an FFP2 respirator (the equivalent of an N95 mask); 16% had an FFP3 respirator (the equivalent of an N99 mask).

To date, the British government hasn’t issued much of a response to the survey, saying only that it has invested more than ₤50 million to better understand long COVID.

I wake up exhausted, the insomnia and night terrors are horrendous as I live through my worst fears every night. Any activity such as eating meals, washing, etc., will mean I have to go to bed for a few hours. I am unable to look after myself or my child, exercise or maintain social relationships. I have no financial security. Long COVID has totally destroyed my life.”
• A salaried general practitioner said: “I can no longer work, finances are ruined. I didn’t have employment protection so am now unemployed and penniless.”

Calls for action from the BMA include the following:

• Financial support for doctors and health care staff with long COVID.
• The recognition of long COVID as an occupational disease among health care workers, along with a definition of the condition that covers all of the debilitating disease’s symptoms.
• Improved access to physical and mental health services to help comprehensive assessment, investigations, and treatment.
• Greater workplace protection for health care staff who risk their lives for others.
• Better support for long COVID sufferers to return to work safely if they can, including a flexible approach to the use of workplace adjustments.

“One would think, given the circumstances under which we fell ill and current workforce shortages, NHS employers would be eager to do everything to facilitate the return to work of people with long COVID,” said Dr. Fearnley. “However, NHS employers are legally required to implement only ‘reasonable adjustments,’ and so things such as extended phased return or adjustments to shift patterns are not always being facilitated. Instead, an increasing number of employers are choosing to terminate contracts.”

Raymond Agius, the BMA’s occupational medicine committee cochair, also put the blame on inadequate safety measures for doctors. Those inadequate measures persist to this day, inasmuch as U.K. hospitals have dropped masking requirements.

“During the COVID-19 pandemic, doctors were left exposed and unprotected at work,” he said in a BMA press release. “They often did not have access to the right PPE. ... Too many risk assessments of workplaces and especially of vulnerable doctors were not undertaken.”

A small minority of doctors who were surveyed said they had access to respiratory protective equipment about the time they contracted COVID-19. Only 11% had access to an FFP2 respirator (the equivalent of an N95 mask); 16% had an FFP3 respirator (the equivalent of an N99 mask).

To date, the British government hasn’t issued much of a response to the survey, saying only that it has invested more than ₤50 million to better understand long COVID.

Adults with asthma who were newly prescribed mepolizumab showed significant improvement in symptoms after 1 year regardless of comorbidities, based on data from 822 individuals.

Comorbidities including chronic rhinosinusitis with polyps (CRSwNP), gastroesophageal reflux disease GERD), anxiety and depression, and chronic obstructive pulmonary disorder (COPD) are common in patients with severe asthma and add to the disease burden, wrote Mark C. Liu, MD, of Johns Hopkins University, Baltimore, and colleagues.

“Some comorbidities, such as CRSwNP, share pathophysiological mechanisms with severe asthma, with interleukin-5 (IL-5),” and treatments targeting IL-5 could improve outcomes, they said.

In the real-world REALITI-A study, mepolizumab, a humanized monoclonal antibody that targets IL-5, significantly reduced asthma exacerbation and oral corticosteroid use in severe asthma patients, they said.

To assess the impact of mepolizumab on patients with comorbidities, the researchers conducted a post hoc analysis of 822 adults with severe asthma, including 321 with CRSwNP, 309 with GERD, 203 with depression/anxiety, and 81 with COPD. The findings were published in the Journal of Allergy and Clinical Immunology: In Practice.

The main outcomes were the rate of clinically significant asthma exacerbations (CSEs) between the 12 months before and after mepolizumab initiation, and the changes from baseline in the daily maintenance use of oral corticosteroids (OCS).

Across all comorbidities, the rate of CSEs decreased significantly from the pretreatment period to the follow-up period, from 4.28 events per year to 1.23 events per year.

“A numerically greater reduction in the rate of CSEs was reported for patients with versus without CRSwNP, whereas the reverse was reported for patients with versus without COPD and depression/anxiety, although the confidence intervals were large for the with COPD subgroup,” the researchers wrote.

The median maintenance dose of oral corticosteroids decreased by at least 50% across all comorbidities after mepolizumab treatment; patients with CRSwNP had the greatest reduction (83%).

In addition, scores on the Asthma Control Questionnaire–5 decreased by at least 0.63 points, and least squared (LS) mean changes in forced expiratory volume per second (FEV₁) increased from baseline across all comorbidities after mepolizumab treatment by at least 74 mL.

Although patients with versus without CRSwNP had greater improvements, patients without GERD, depression/anxiety, and COPD had greater improvements than did those without the respective conditions with the exception of greater FEV₁ improvement in patients with vs. without COPD.

“Patients with severe asthma and comorbid CRSwNP are recognized as having a high disease burden, as demonstrated by more frequent exacerbations,” the researchers wrote in their discussion. “Mepolizumab may serve to reduce the disease burden of this high-risk group by targeting the common pathophysiological pathway of IL-5 and eosinophilic-driven inflammation because it has proven clinical benefits in treating asthma and CRSwNP separately and together,” and the current study findings support the use of mepolizumab for this population in particular, they said.

The findings were limited by several factors including the incomplete data for voluntary assessments, the post hoc design and relatively small numbers of patients in various subgroups, notably COPD, and the potential inaccurate diagnosis of COPD, the researchers noted.

“Nevertheless, because the amount of improvement in each outcome following mepolizumab treatment differed depending on the comorbidity in question, our findings highlight the impact that comorbidities and their prevalence and severity have on outcomes,” and the overall success of mepolizumab across clinical characteristics and comorbidities supports the generalizability of the findings to the larger population of adults with severe asthma, they concluded.

The study was supported by GlaxoSmithKline. Dr. Liu disclosed research funding from GSK, Boehringer Ingelheim, and Gossamer Bio, and participation on advisory boards for AstraZeneca, GSK, and Gossamer Bio.

Severe COVID infections may lead to lasting damage to the immune system, new research finds.

The small study, published in Cell and funded by the National Institutes of Health, details how immune cells were analyzed through blood samples collected from 38 patients recovering from severe COVID and other critical illnesses, and from 19 healthy people. Researchers from Weill Cornell Medicine, New York, and The Jackson Laboratory for Genomic Medicine, Farmington, Conn., found through isolating hematopoietic stem cells that people recovering from severe bouts of COVID had changes to their DNA that were passed down to offspring cells.

The research team, led by Steven Josefowicz, PhD, of Weill Cornell’s pathology department, and Duygu Ucar, PhD, associate professor at The Jackson Laboratory for Genomic Medicine, discovered that this chain reaction of stem cell changes caused a boost in the production of monocytes. The authors found that, due to the innate cellular changes from a severe case of COVID, patients in recovery ended up producing a larger amount of inflammatory cytokines, rather than monocytes – distinct from samples collected from healthy patients and those recovering from other critical illnesses.

These changes to patients’ epigenetic landscapes were observed even a year after the initial COVID-19 infection. While the small participant pool meant that the research team could not establish a direct line between these innate changes and any ensuing health outcomes, the research provides us with clues as to why patients continue to struggle with inflammation and long COVID symptoms well after they recover.

While the authors reiterate the study’s limitations and hesitate to make any clear-cut associations between the results and long-term health outcomes, Wolfgang Leitner, PhD, from the NIH’s National Institute of Allergy and Infectious Diseases, predicts that long COVID can, at least in part, be explained by the changes in innate immune responses.

“Ideally, the authors would have had cells from each patient before they got infected, as a comparator, to see what the epigenetic landscape was before COVID changed it,” said Dr. Leitner. “Clear links between the severity of COVID and genetics were discovered already early in the pandemic and this paper should prompt follow-up studies that link mutations in immune genes with the epigenetic changes described here.”

Dr. Leitner said he had some initial predictions about the long-term impact of COVID-19, but he had not anticipated some of what the study’s findings now show.

“Unlike in the case of, for example, influenza, where the lungs go into ‘repair mode’ after the infection has been resolved – which leaves people susceptible to secondary infections for up to several months – this study shows that after severe COVID, the immune system remains in ‘emergency mode’ and in a heightened state of inflammation,” said Dr. Leitner.

“That further aggravates the problem the initial strong inflammation causes: even higher risk of autoimmune disease, but also, cancer.”

Commenting on the findings, Eric Topol, MD, editor-in-chief of Medscape Medical News, said the study presents “evidence that a key line of immune cells are essentially irrevocably, epigenetically altered and activated.

“You do not want to have this [COVID],” he added.

The study also highlights the researchers’ novel approach to isolating hematopoietic stem cells, found largely in bone marrow. This type of research has been limited in the past because of how costly and invasive it can be to analyze cells in bone marrow. But, by isolating and enriching hematopoietic stem cells, the team can decipher the full cellular diversity of the cells’ bone marrow counterparts.

“This revelation opened the doors to study, at single-cell resolution, how stem cells are affected upon infection and vaccination with a simple blood draw,” representatives from the Jackson lab said in a press release.

It’s been estimated that up to one-third of people who survive acute SARS-CoV-2 infection will suffer a post-viral syndrome with lingering neurologic and other symptoms – now known as long COVID or neurological postacute sequelae of SARS-CoV-2 infection (Neuro-PASC).

However, new research suggests that may be an underestimate and that far more people may be suffering from long COVID without ever having tested positive for the virus. Researchers found a significant proportion of patients in their small study who had never tested positive for COVID-19 but who were having symptoms of long COVID nevertheless showed evidence of immune responses consistent with previous exposure.

“We estimate that millions of people got COVID in the U.S. during the first year of the pandemic and then developed long COVID, yet they did not get a positive COVID diagnosis because of testing limitations,” Igor J. Koralnik, MD, of Northwestern Medicine Comprehensive COVID-19 Center in Chicago, said in an interview.

He noted that many post-COVID-19 clinics in the United States don’t accept people with long COVID symptoms who do not have a positive test result.

Patients with long COVID symptoms but without laboratory evidence of prior infection, “who have often been rejected and stigmatized, should feel vindicated by the results of our study,” Dr. Koralnik said.

“We think that those patients deserve the same clinical care as those with a positive test, as well as inclusion in research studies. This is what we are doing at Northwestern Medicine’s Comprehensive COVID[-19] Center,” Dr. Koralnik added.

The study was published online in the journal Neurology: Neuroimmunology & Neuroinflammation.

Delayed care

The researchers measured SARS-CoV-2-specific humoral and cell-mediated immune responses against nucleocapsid protein and spike proteins, which indicate a prior COVID-19 infection, in 29 patients with post-viral syndrome after suspected COVID-19, including neurologic symptoms such as cognitive impairment, headache, and fatigue, but who did not have a confirmed positive COVID-19 test.

They did the same in 32 age- and sex-matched COVID long haulers with confirmed Neuro-PASC and 18 healthy controls with none of the symptoms of long COVID and no known exposure to SARS-CoV-2 or positive test result.

They found that 12 of the 29 patients (41%) with post-viral syndrome (but no positive COVID-19 test) had detectable humoral and cellular immune responses consistent with prior exposure to SARS-CoV-2. Three-quarters harbored antinucleocapsid and 50% harbored antispike responses.

“Our data suggest that at least 4 million people with post-viral syndrome similar to long COVID may indeed have detectable immune responses to support a COVID diagnosis,” Dr. Koralnik said in a news release.

The 12 patients with post-viral syndrome but without a confirmed COVID-19 test had neurologic symptoms similar to those of patients with confirmed Neuro-PASC.

However, lack of a confirmed COVID-19 diagnosis likely contributed to the 5-month delay in the median time from symptom onset to clinic visit, the researchers said. They were evaluated at a median of 10.7 months vs. 5.4 months for Neuro-PASC patients.

Dr. Koralnik said in an interview that the “most important take-home message” of the study is that patients with post-viral syndrome often present with clinical manifestations similar to those of confirmed patients with Neuro-PASC, suggesting that a positive result by commercially available SARS-CoV-2 diagnostic test should not be a prerequisite for accessing care.

Patients with post-viral syndrome may benefit from the same clinical care as confirmed patients with Neuro-PASC, and the absence of a positive SARS-CoV-2 test should not preclude or delay treatment, he added.

Dr. Koralnik said in an interview that the “most important take-home message” of the study is that patients with post-viral syndrome often present with clinical manifestations similar to those of confirmed patients with Neuro-PASC, suggesting that a positive result by commercially available SARS-CoV-2 diagnostic test should not be a prerequisite for accessing care.

Patients with post-viral syndrome may benefit from the same clinical care as confirmed patients with Neuro-PASC, and the absence of a positive SARS-CoV-2 test should not preclude or delay treatment, he added.

People who have been infected with the COVID-19 virus have a greater risk of many long-term health conditions, including diabetes, lung problems, fatigue, blood clots, and disorders affecting the gastrointestinal and musculoskeletal systems.

That is the finding of a new study from Washington University in St. Louis. The school distributed a press release about the study, which was published in the journal Nature Medicine.

“Some estimates show more than 90% of the U.S. population has been infected with COVID-19,” Ziyad Al-Aly, chief of research and development at Veterans Affairs St. Louis Health Care System and clinical epidemiologist at Washington University, told the St. Louis Post–Dispatch. “Doctors need to realize that their patients could be at risk of these conditions, be it heart disease or lung problems or brain problems – they’re at risk.”

The researchers compared the health records for 138,000 patients who had been infected with those of 6 million who had not. They followed 80 health conditions associated with long COVID for 2 years. They used unnamed records from the VA.

“There was really nothing at all looking at what happens to people at two years after the infection,” Dr. Al-Aly said. “So we decided to take a look.”

Patients who hadn’t been hospitalized within 30 days of infection had a higher risk of death 6 months after recovery, and a higher risk of hospitalization within 18 months. They had higher risk of diabetes, fatigue, joint pain, and other problems compared with people who had not been infected.

“In the nonhospitalized group, risks remained elevated for several problems, for several organ systems,” Dr. Al-Aly said. “For the people who were hospitalized, the risk was ubiquitous across all organ systems. It really spans the gamut with respect to the organ systems that are affected.”

People who had been hospitalized had a 65% greater risk of illnesses after 2 years. Nonhospitalized patients had just a 35% greater risk.

By now, concerns about COVID-related lawsuits have faded into the rear view mirror for most physicians.

But just when COVID lawsuits appear to be dwindling out, legal experts see a new lawsuit risk on the horizon – long COVID claims. While some say it’s doubtful the claims will succeed, the lawsuits could still create legal headaches for doctors in the form of time and money.

Long COVID claims are defined as complaints that allege that a diagnosis of long COVID was missed or delayed and that caused harm or injury. Lawsuits may also include claims in which patients allege that they were misdiagnosed as having long COVID when they were really suffering from another condition.

So far, a handful of long COVID claims have come down the pipeline, said Peter A. Kolbert, JD, senior vice president of claims and litigation services for Healthcare Risk Advisors, part of TDC Group.

“This is an area that is emerging as we speak,” Mr. Kolbert said. “We are starting to see these claims trickle in.”

In a recent case, for example, a patient sued her primary care physician for negligence, alleging her original SARS-CoV-2 infection was mismanaged and that this led to permanent neuropathy from long COVID. Had the patient been treated appropriately, the patient contends, she would not have developed long COVID or the resulting neuropathy, said Mr. Kolbert. An outcome in the case has not yet been reached, added Mr. Kolbert, who heard about the claim from a colleague.

The increase in the number of lawsuits raises concerns about how courts and juries might decide long COVID claims when so much about the condition is still unknown and best treatment practices are still developing. Research shows that long COVID occurs in at least 10% of cases of SARS-CoV-2 infection, and more than 200 symptoms have been identified. A Kaiser Family Foundation study found that 15% of the U.S. population believe they have experienced the symptoms of long COVID at some point, and 6% of people believe they currently have long COVID.

The risk of long COVID lawsuits underscores the importance of physicians taking proactive steps to protect themselves from liability when treating patients who might have the condition, say legal experts.

“There are legal standards that say new, unestablished scientific principles shouldn’t be first tested by a jury, they should be recognized and established within their [professional] area,” Mr. Kolbert said. “While we are seeing lawsuits related to long COVID, I think it is truly putting the cart before the horse, because there needs to be societal recognition that we’re still learning how to define and treat long COVID.”
 

What are patients alleging?

In the few long COVID claims that have arisen, some complaints have alleged delay in the recognition and treatment of long COVID, according to Mr. Kolbert. There have also been claims that physicians failed to refer a patient with long COVID to a specialist in a timely way and that this results in the patient’s experiencing chronic fatigue or a neuropathy.

Fatigue is one of the most common symptoms associated with long COVID, according to recent studies. Other symptoms include postexertional malaise, brain fog, and gastrointestinal problems.

Another rising legal theme is failure to adequately communicate with patients about what long COVID is and what it entails.

Whether plaintiffs who bring long COVID claims will be successful in court remains a question.

Andrew D. DeSimone, JD, a Lexington, Ky.–based medical malpractice defense attorney, said he has not seen any claims involving long COVID. He added that a long COVID claim would be challenging to prove, considering the standard of care for treating the condition is still evolving. Plaintiffs in a medical malpractice action must prove that physicians owed a duty of care to the patient, that the doctor breached that duty by failing to conform to the standard of care, and that the breach caused an injury that harmed the patient.

Mr. DeSimone also doubts whether juries would be very sympathetic to such plaintiffs.

“There’s a lot of fatigue around COVID still,” he said. “I don’t know if a jury would buy into someone claiming long COVID. I think the claim would have a hard time gaining traction. Not that it’s impossible.”

Another unanswered question is whether legal protections enacted by states during the pandemic might apply to long COVID claims.

Shortly after the pandemic started, most states enacted laws or executive orders that shielded physicians from liability claims relating to the prevention and treatment of COVID-19, unless gross negligence or willful misconduct is proved. The U.S. Department of Health and Human Services published a declaration under the Public Readiness and Emergency Preparedness Act (PREP Act) that provided liability immunity to health care professionals for any activity related to medical countermeasures against COVID-19.

Some of these state immunities have since expired. Other states have extended their legal protections for short periods. In Indiana, for example, physicians and businesses are protected until Dec. 31, 2024, from civil tort actions that allege damages arising from COVID-19.

It’s possible that in long COVID lawsuits, physicians would be protected by the immunities unless the cases come after the protections expire, said J. Richard Moore, a medical liability defense attorney based in Indianapolis.

“I could foresee long COVID claims that don’t accrue until after December 2024, meaning it only becomes clear that a patient is struggling with long COVID–related symptoms after that date,” he said. “That could result in COVID claims that do not fall under the immunities.”

Mr. Moore said that if long COVID claims become truly problematic, the legislature could extend the immunities.

Other states, such as Washington, have statutes in place that increase the burden of proof for plaintiffs in cases in which care is affected by COVID and/or the treating of COVID. Elizabeth A. Leedom, a Seattle-based medical liability defense attorney, said the law would likely encompass long COVID claims if the care and treatment at issue occurred during the COVID state of emergency.

Compliance with current treatment guidelines is likely to be a good defense against any claim of delay/failure to diagnose COVID, including long COVID, she said.

Mr. Kolbert, however, doubts that the state immunities would protect against the claims.

“Courts are enforcing qualified immunities as to [traditional] COVID claims. However, I suspect that long COVID claims will fall into a category of traditional medical malpractice claim, such as delay in or failure to diagnose,” he said. In such cases, physicians “may not be able to take advantage of state-qualified immunities. Of course, this will depend upon the language of each state’s qualified immunity provisions.”

As for the statute of limitations, the clock generally starts running either when the alleged negligent conduct occurred or when the patient knew or, in the exercise of ordinary diligence, should have known, that they had been harmed by the alleged negligence, Mr. Moore said. Statutes of limitations are state specific, but the majority of states mandate a 2- to 3-year limit between the injury and the filing of a claim.

So, while the statute of limitations may be soon expiring for alleged harm that occurred during the pandemic, for patients newly diagnosed with long COVID or who have just discovered associated injuries, the clock may have just started ticking.
 

How to protect yourself against suits

Avoiding liability associated with long COVID involves the traditional legal guidance physicians are used to hearing, but with an added factor, Mr. Kolbert said.

There always needs to be communication with patients regarding the disease process, but in this area, there needs to be strong communication as to whether patients have had COVID in the past and what symptoms they are experiencing, he said. Physicians should ensure that patients know that long COVID may present in a variety of ways and that there is no definitive test for long COVID.

Physicians should document when the patient has been instructed to follow up and should take necessary steps to ensure the patient returns for follow-up care, he added.

On the opposite side of the spectrum is making sure not to assume a condition or symptom is the result of long COVID, he said. Care should be taken not to diagnose long COVID without excluding traditional causes.

“Ensure that patients know that COVID is not over, per se, and that science supports vaccination,” Mr. Kolbert said. “The best defense here is a strong communicative offense, engaging with the patient and thoughtfully charting about this.”

Long COVID most often strikes seniors and adults, but children are also affected, even though they get less attention, new research shows.

Experts noted that the disease poses particular challenges for children and the doctors who treat them.

Parents and doctors need to be on the lookout for symptoms of long COVID in children and teens that might be easily missed or misdiagnosed, according to physicians and family groups.

Children are at lower risk for contracting COVID and often experience milder symptoms. But the virus is now widespread, and a recent study found that around 16% of pediatric patients with COVID go on to develop symptoms that last more than 3 months – the working definition of long COVID.

Parents and doctors are calling for more studies and more awareness.

Diane Sheehan, who lives outside Charlotte, N.C., says she was an active person and is now permanently disabled from long COVID. Her teenage son has it too and is still recovering.

He contracted COVID after a school event, she said. He had a mild case, but then he started experiencing dizziness and would even experience loss of consciousness when he stood up suddenly. After he contracted the virus a second time, he was bedridden for 8 months.

The staff at Hackensack Meridian Health, a pediatric long COVID clinic in New Jersey, has been working with area schools to help teachers and school nurses recognize possible long COVID in children and young people. The clinic is one of about a dozen in the United States that specializes in pediatric cases.

Katherine Clouser, MD, a pediatric hospital medicine specialist, has been with the clinic since it opened in 2021, and she’s seen a steady flow of patients. Some get better, but she sees a few new cases each week.

“We are seeing children who are having a difficult time returning to school and sports,” she said.

The clinic is having success with a mix of approaches, including intensive rehabilitation, talk therapy, and some off-label use of nirmatrelvir (Paxlovid), an antiviral now being studied as a treatment for long COVID through a National Institutes of Health clinical trials initiative that was announced last month.

Treatment depends on symptoms and is determined on a case-by-case basis, Dr. Clouser said.

Families of her patients are grateful, she added.

“We hear a lot of parents who were desperate for someone to believe them – or someone who knows about it,” she said.

A recent review of more than 30 studies with about 15,000 participants concluded that 16.2% (95% confidence interval, 8.5%-28.6%) of the pediatric participants experienced one or more persistent symptoms of long COVID at least 3 months after acute infection.

Estimates of the number of children and youth with long COVID have varied widely. A 2022 study put the number at more than 25% of cases, but the American Academy of Pediatrics notes that estimates of the percentage of children infected with SARS-CoV-2 who go on to have long COVID range from 2% to 66%.

The federal Recover Initiative has enrolled more than 10,000 children and youth – a number it plans to double – and studies of electronic health records are underway. The Recover pediatric team is also setting up a cohort that they plan to follow into 2025.

Some clinics are having luck treating young people with approaches ranging from special diets to off-label medication.

David W. Miller, MD, who runs the long COVID clinic at the UH Rainbow Babies and Children’s Hospital, Cleveland, said he’s seen about 250 patients.

A warning sign of long COVID in children is profound fatigue, he said.

“It’s the most common symptom,” Dr. Miller said. “They feel like they have the flu all the time.”

Many also experience orthostatic hypotension on standing, triggering dizziness.

He said his team targets symptom groups. Initial management consists of a diet without sugar or refined carbohydrates. Skipping pasta and sweets can be hard for young people, but Dr. Miller said sometimes the diet alone helps.

Many have vitamin D and iron deficiencies. Others need help getting a good night’s sleep. He’s treated 50 with off-label low-dose naltrexone.

Some people with long COVID – both young and old – complain about being misdiagnosed as having depression. Dr. Miller says he see a lot of anxiety – some situational and some biochemical – in pediatric patients. But he cautions doctors not to treat their illness solely as a mental health problem.

His advice: If a young person or child experiences a major change in his or her regular level of functioning or has multiple COVID symptoms that don’t go away after several months, parents and doctors should consider long COVID as a possible cause.

Dr. Miller said most of his patients get better over time with some treatments: “We see improvement in the majority of kids who can stick to the regimen,” such as a sugar-free diet, supplements, and adequate sleep. Recovery has been slow and incomplete for Diane Sheehan and her son. She was training as a permanent make-up artist, she said, but now has hand tremors that make work impossible.

She has found doctors who treat some of her symptoms with antihistamines, and her son has benefited from physical therapy.

But for now, her son is passing on a scholarship he was awarded to attend North Carolina State University this year. Instead, he’s living at home and going to a local college.

Ms. Sheehan urges parents to be on the alert for signs that their children might have long COVID, which can be confused with many other conditions.

Long COVID most often strikes seniors and adults, but children are also affected, even though they get less attention, new research shows.

Experts noted that the disease poses particular challenges for children and the doctors who treat them.

Parents and doctors need to be on the lookout for symptoms of long COVID in children and teens that might be easily missed or misdiagnosed, according to physicians and family groups.

Children are at lower risk for contracting COVID and often experience milder symptoms. But the virus is now widespread, and a recent study found that around 16% of pediatric patients with COVID go on to develop symptoms that last more than 3 months – the working definition of long COVID.

Parents and doctors are calling for more studies and more awareness.

Diane Sheehan, who lives outside Charlotte, N.C., says she was an active person and is now permanently disabled from long COVID. Her teenage son has it too and is still recovering.

He contracted COVID after a school event, she said. He had a mild case, but then he started experiencing dizziness and would even experience loss of consciousness when he stood up suddenly. After he contracted the virus a second time, he was bedridden for 8 months.

The staff at Hackensack Meridian Health, a pediatric long COVID clinic in New Jersey, has been working with area schools to help teachers and school nurses recognize possible long COVID in children and young people. The clinic is one of about a dozen in the United States that specializes in pediatric cases.

Katherine Clouser, MD, a pediatric hospital medicine specialist, has been with the clinic since it opened in 2021, and she’s seen a steady flow of patients. Some get better, but she sees a few new cases each week.

“We are seeing children who are having a difficult time returning to school and sports,” she said.

The clinic is having success with a mix of approaches, including intensive rehabilitation, talk therapy, and some off-label use of nirmatrelvir (Paxlovid), an antiviral now being studied as a treatment for long COVID through a National Institutes of Health clinical trials initiative that was announced last month.

Treatment depends on symptoms and is determined on a case-by-case basis, Dr. Clouser said.

Families of her patients are grateful, she added.

“We hear a lot of parents who were desperate for someone to believe them – or someone who knows about it,” she said.

A recent review of more than 30 studies with about 15,000 participants concluded that 16.2% (95% confidence interval, 8.5%-28.6%) of the pediatric participants experienced one or more persistent symptoms of long COVID at least 3 months after acute infection.

Estimates of the number of children and youth with long COVID have varied widely. A 2022 study put the number at more than 25% of cases, but the American Academy of Pediatrics notes that estimates of the percentage of children infected with SARS-CoV-2 who go on to have long COVID range from 2% to 66%.

The federal Recover Initiative has enrolled more than 10,000 children and youth – a number it plans to double – and studies of electronic health records are underway. The Recover pediatric team is also setting up a cohort that they plan to follow into 2025.

Some clinics are having luck treating young people with approaches ranging from special diets to off-label medication.

David W. Miller, MD, who runs the long COVID clinic at the UH Rainbow Babies and Children’s Hospital, Cleveland, said he’s seen about 250 patients.

A warning sign of long COVID in children is profound fatigue, he said.

“It’s the most common symptom,” Dr. Miller said. “They feel like they have the flu all the time.”

Many also experience orthostatic hypotension on standing, triggering dizziness.

He said his team targets symptom groups. Initial management consists of a diet without sugar or refined carbohydrates. Skipping pasta and sweets can be hard for young people, but Dr. Miller said sometimes the diet alone helps.

Many have vitamin D and iron deficiencies. Others need help getting a good night’s sleep. He’s treated 50 with off-label low-dose naltrexone.

Some people with long COVID – both young and old – complain about being misdiagnosed as having depression. Dr. Miller says he see a lot of anxiety – some situational and some biochemical – in pediatric patients. But he cautions doctors not to treat their illness solely as a mental health problem.

His advice: If a young person or child experiences a major change in his or her regular level of functioning or has multiple COVID symptoms that don’t go away after several months, parents and doctors should consider long COVID as a possible cause.

Approximately one-quarter of adults who experience long COVID report activity limitations that do not change over time, based on data from national sample of nonhospitalized individuals.

Symptoms of long COVID, an ongoing medical condition that occurs in the wake of COVID-19 infection, include respiratory, neurologic, cardiovascular, or other complications that may last for weeks, months, or years after infection.

Current estimates of the incidence of long COVID in the United States range from 7.5% to 41%, according to Nicole D. Ford, PhD, of the Centers for Disease Control and Prevention, Atlanta, and colleagues. Long COVID has shown a significant effect on patients’ quality of life, functional status, and ability to work, but the impact on activity limitation in particular has not been examined, the researchers said.

In a study published in the Centers for Disease Control and Prevention’s Morbidity and Mortality Weekly Report (MMWR), the researchers reviewed data from surveys conducted between June 1 and 13, 2022, and June 7 and 19, 2023. The data came from the Census Bureau’s Household Pulse Survey (HPS), a cross-sectional national survey designed to measure the social and economic effects of COVID-19 on U.S. households. Surveys were conducted in 2-week cycles (2 weeks on, 2 weeks off). Questions about long COVID were added to the survey beginning on June 1, 2022, and questions about activity limitations from long COVID were added on Sept. 14, 2022, including questions about participants’ abilities to perform daily activities before and after COVID-19 infection.

Overall, the prevalence of long COVID decreased from 7.5% to 6.0% in U.S. adults aged 18 years and older during the study period. However, when stratified by age group, the decline was significant only in adults older than 60 years, and 1 in 10 adults with a history of COVID-19 reported long COVID at the end of the study period.

Among respondents with long COVID, 26.4% of respondents for time period of June 7-19, 2023, reported significant activity limitations, which remained unchanged over time, with no clear pattern in activity limitations across age groups, the researchers said.

Prevalence of long COVID was highest for individuals in middle adulthood (aged 30-39 years, 40-49 years, and 50-59 years) and lowest for younger adults (18-29 years) and older adults (aged 60 years and older). The prevalence of long COVID decreased by 1.16% per survey cycle between the June 1-13 and Jan. 4-16 cycles, but then remained stable, with a decrease of 0.01% per cycle between June 1-13, 2022, and Jan. 4-16, 2023.

Previous studies have shown that activity limitations resulting from long COVID can significantly affect quality of life and functional status, as well as the ability to work or care for others. A recent study in the United Kingdom showed that quality of life scores among long COVID patients were similar to those of individuals with advanced cancer, and more than half of the long COVID patients reported moderately severe functional impairment. “The larger economic and societal impact of long COVID could be far-reaching if working-age adults are unable to maintain employment or care for children or aging parents,” the researchers said.

The current study findings were limited by several factors including potential coverage bias in the survey sample, the relatively low survey response rate, and the inability to collect data on duration of symptoms, COVID-19 vaccination status, treatment during acute infection, and time since COVID-19 illness; any of these factors could affect the reported prevalence of long COVID, the researchers noted.

However, the results suggest the need for continued attention to COVID-19 prevention efforts, including not only staying current with recommended COVID-19 vaccination, but also planning for symptom management and health care service needs of long COVID patients, they concluded.
 

More data are needed to tease out patterns

“Physicians and patients are still trying to understand long COVID and its implications for the health of affected individuals,” said Noel Deep, MD, in an interview.

The current study shows a prevalence of long COVID in approximately 11% of COVID patients, which is a significant number, said Dr. Deep, a general internist in private practice in Antigo, Wisc., who was not involved in the study. Dr. Deep also serves as chief medical officer and a staff physician at Aspirus Langlade Hospital in Antigo.

The study also was useful to illustrate a decline in the incidence of people affected by long COVID symptoms in the United States and in other countries, he said.

Dr. Deep noted that despite the persistent prevalence of long COVID symptoms overall, he was encouraged by the findings that older adults “who tend to have other underlying health conditions that could put them at a higher risk for adverse health outcomes” reported fewer long COVID symptoms than younger adults.

However, he noted that the high incidence of long COVID symptoms in able-bodied individuals in their 30s and 40s may affect their the economic situations as well as their ability to care for elderly relatives and children who might be dependent on them.

“Physicians and other clinicians should be aware of the symptoms and impacts caused by long COVID,” Dr. Deep said in an interview. “These individuals usually present with a myriad of vague and varying symptoms. Physicians should be cognizant of this situation, ask about previous infection with COVID-19, and utilize the resources of long COVID clinics where available,” he said.

Several factors can affect the assessment and management of patients with long COVID symptoms in primary care practices, said Dr. Deep. First and foremost are the time constraints of detailed evaluation and testing, he said.

Second, primary care clinicians need to be aware of the different symptoms that may be indicative of long COVID including fatigue, neurocognitive symptoms such as brain fog or memory disturbance, respiratory symptoms, and cardiovascular symptoms, as well as olfactory and gustatory symptoms. “These symptoms can be confounded by underlying health conditions, especially in elderly individuals,” he noted.

“Recommendations and guidelines are evolving regarding the evaluation and management of patients with long COVID that should help physicians and other clinicians in the future,” said Dr. Deep.

In the meantime, having a high index of suspicion, paying attention to the symptoms described by the patient, and taking a proper history with regard to previous COVID-19 infection should help overcome some of these challenges, he said.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Deep had no financial conflicts to disclose and serves on the Editorial Advisory Board of Internal Medicine News.
