Covid ICYMI

As many as 87% of patients experience symptoms after COVID-19 infection that last 2 months or more, one of the most common being chest pain. And chronic chest discomfort may persist in some individuals for years after COVID, warranting future studies of reliable treatments and pain management in this population, a new study shows.

“Recent studies have shown that chest pain occurs in as many as 89% of patients who qualify as having long COVID,” said Ansley Poole, an undergraduate student at the University of South Florida, Tampa, who conducted the research under the supervision of Christine Hunt, DO, and her colleagues at Mayo Clinic, Jacksonville, Fla.

The findings, though preliminary, shed light on the prevalence, current treatments, and ongoing challenges in managing symptoms of long COVID, said Ms. Poole, who presented the research at the annual Pain Medicine Meeting sponsored by the American Society of Regional Anesthesia and Pain Medicine.

Long COVID, which affects an estimated 18 million Americans, manifests approximately 12 weeks after the initial infection and can persist for 2 months or more. Ms. Poole and her team set out to identify risk factors, treatment options, and outcomes for patients dealing with post-COVID chest discomfort.

The study involved a retrospective chart review of 520 patients from the Mayo Clinic network, narrowed down to a final sample of 104. To be included, patients had to report chest discomfort 3-6 months post COVID that continued for 3-6 months after presentation, with no history of chronic chest pain before the infection.

The researchers identified no standardized method for the treatment or management of chest pain linked to long COVID. “Patients were prescribed multiple different treatments, including opioids, post-COVID treatment programs, anticoagulants, steroids, and even psychological programs,” Ms. Poole said.

The median age of the patients was around 50 years; more than 65% were female and over 90% identified as White. More than half (55%) had received one or more vaccine doses at the time of infection. The majority were classified as overweight or obese at the time of their SARS-CoV-2 infection.

Of the 104 patients analyzed, 30 were referred to one or more subspecialties within the pain medicine department, 23 were hospitalized, and 9 were admitted to the intensive care unit or critical care.

“Fifty-three of our patients visited the ER one or more times after COVID because of chest discomfort; however, only six were admitted for over 24 hours, indicating possible overuse of emergency services,” Ms. Poole noted.

Overall, chest pain was described as intermittent instead of constant, which may have been a barrier to providing adequate and timely treatment. The inconsistent presence of pain contributed to the prolonged suffering some patients experienced, Ms. Poole noted.

The study identified several comorbidities, potentially complicating the treatment and etiology of chest pain. These comorbidities – when combined with COVID-related chest pain – contributed to the wide array of prescribed treatments, including steroids, anticoagulants, beta blockers, and physical therapy. Chest pain also seldom stood alone; it was often accompanied by other long COVID–related symptoms, such as shortness of breath.

“Our current analysis indicates that chest pain continues on for years in many individuals, suggesting that COVID-related chest pain may be resistant to treatment,” Ms. Poole reported.

The observed heterogeneity in treatments and outcomes in patients experiencing long-term chest discomfort after COVID infection underscores the need for future studies to establish reliable treatment and management protocols for this population, said Dalia Elmofty, MD, an associate professor of anesthesia and critical care at the University of Chicago, who was not involved in the study. “There are things about COVID that we don’t fully understand. As we’re seeing its consequences and trying to understand its etiology, we recognize the need for further research,” Dr. Elmofty said.

“So many different disease pathologies came out of COVID, whether it’s organ pathology, myofascial pathology, or autoimmune pathology, and all of that is obviously linked to pain,” Dr. Elmofty told this news organization. “It’s an area of research that we are going to have to devote a lot of time to in order to understand, but I think we’re still in the very early phases, trying to fit the pieces of the puzzle together.”

A 49-year-old woman, previously recuperating from COVID-19, was found unconscious at her workplace, setting off a chain of events that would ultimately lead to an unexpected diagnosis.

This case report was published in the New England Journal of Medicine.

Noting the patient’s confusion and aphasia, emergency medical services were alerted, and she was taken to the emergency department of Massachusetts General Hospital. Initial examination revealed aphasia and coordination difficulties. However, imaging studies, including CT angiography, showed no signs of stroke or other neurological abnormalities.

The patient’s coworkers had observed that she appeared “unwell.” Her medical history included hypertension, which was managed with amlodipine, and there was no known family history of neurologic disorders.

During the examination, her vital signs were within normal ranges.

The patient’s potassium level of 2.5 mmol/L was noteworthy, indicating hypokalemia. Additionally, the patient presented with anemia and thrombocytopenia. Additional laboratory results unveiled thrombotic thrombocytopenic purpura (TTP), a rare blood disorder characterized by microangiopathic hemolytic anemia. The microscopic examination of a peripheral blood smear confirmed the extent of thrombocytopenia and was particularly notable for the increased number of schistocytes. The patient’s peripheral blood smear revealed five or six schistocytes per high-power field, constituting approximately 5% of the red cells. This significant number of schistocytes aligned with the severity of anemia and thrombocytopenia, confirming the diagnosis of microangiopathic hemolytic anemia.

Acquired TTP is an autoimmune condition driven by antibody-mediated clearance of the plasma enzyme ADAMTS13 (a disintegrin and metalloproteinase with thrombospondin motif 13). Confirmatory laboratory testing for ADAMTS13 takes 1-3 days; therefore, therapeutic plasma exchange with glucocorticoid therapy and rituximab was initiated, which promptly improved her condition.

In this patient, the ADAMTS13 activity level was severely reduced (< 5%; reference value > 67%), and the inhibitor was present (1.4 inhibitor units; reference value ≤ 0.4).

Rectal cancer was diagnosed in this patient 2 months after the diagnosis of acquired TTP.

After undergoing four weekly infusions of rituximab and a 2-month tapering course of glucocorticoids, the patient experienced a relapse, approximately 6 months following the acquired TTP diagnosis. In response, therapeutic plasma exchange and glucocorticoid therapy were administered. There is a possibility that the underlying cancer played a role in the relapse. To minimize the risk for recurrence, the patient also received a second round of rituximab.

While establishing a clear cause is difficult, acquired TTP often appears to arise in connection with either an immune trigger, such as a viral infection, or immune dysregulation associated with another autoimmune disease or ongoing cancer. In this case, 4 weeks before the acquired TTP diagnosis, the patient had experienced COVID-19, which was likely to be the most probable trigger. However, rectal cancer was also identified in the patient, and whether these conditions are directly linked remains unclear.

ANAHEIM, CALIF. – Gargling and nasal rinsing with saltwater several times a day appeared to be associated with significantly lower COVID-19 hospitalization rates in a small, randomized, double-blind, controlled study.

“The hypothesis was that interventions that target the upper respiratory tract may reduce the frequency and duration of upper respiratory symptoms associated with COVID-19,” said Sebastian Espinoza, first author of the study; he is with Trinity University, San Antonio.

Adults aged 18-65 years who tested positive for SARS-CoV-2 on polymerase chain reaction (PCR) testing between 2020 and 2022 were randomly selected to use low- or high-dose saltwater regimens for 14 days at the Harris Health System, Houston. For patients to be included in the study, 14 days had to have elapsed since the onset of any symptoms associated with COVID.

The low dose was 2.13 grams of salt dissolved in 8 ounces of warm water, and the high dose was 6 grams. Participants gargled the saltwater and used it as a nasal rinse for 5 minutes four times a day.

Primary outcomes included frequency and duration of symptoms associated with SARS-CoV-2 infection; secondary outcomes included admission to the hospital or the intensive care unit, mechanical ventilatory support, or death.

The findings were presented in a poster at the annual meeting of the American College of Allergy, Asthma, and Immunology.

Fifty-eight people were randomly assigned to either the low-saline (n = 27) or the high-saline (n = 28) group; three patients were lost to follow-up in both these groups. The reference control population consisted of 9,398 people with confirmed SARS-CoV-2 infection. Rates of vaccination were similar for all participants.

Hospitalization rates in the low- (18.5%) and high- (21.4%) saline groups were significantly lower than in the reference control population (58.8%; P < .001). No significant differences were noted in other outcomes among these groups.

The average age of patients in the control population (n = 9,398) was 45 years. The average age was similar in the low- and high-saline groups. In the low-saline group (n = 27), the average age was 39, and in the high-saline group, the average age was 41.

In all three groups, body mass index was between 29.6 and 31.7.

Exclusion criteria included chronic hypertension or participation in another interventional study.
 

‘Low risk, small potential benefit’

Allergist Zach Rubin, MD, a spokesperson for the ACAAI, said in an interview that the findings are in line with other small studies that previously reported some benefit in using nasal saline irrigation and gargling to treat a SARS-CoV-2 infection.

“This is a type of intervention that is low risk with some small potential benefit,” he said.

The researchers did not evaluate the potential reason for the saline regimen’s association with fewer hospitalizations, but Dr. Rubin said, “It may be possible that nasal saline irrigation and gargling help improve viral clearance and reduce the risk of microaspiration into the lungs, so it may be possible that this intervention could reduce the risk of pneumonia, which is a major cause of hospitalization.”

Dr. Rubin, who is an allergist at Oak Brook Allergists, Ill., said, “I generally recommend nasal saline irrigation to my patients for allergic rhinitis and viral upper respiratory infections already. It can help reduce symptoms such as nasal congestion, rhinorrhea, postnasal drip, and sinus pain and pressure.”

The intervention may be reasonable beyond an adult population, he said.

“This could be used for pediatric patients as well, if they are developmentally ready to try this intervention,” he said.

Mr. Espinoza said further study is warranted, but he said that if confirmed in later trials, the simple intervention may be particularly helpful in low-resource settings.

Mr. Espinoza and Dr. Rubin have disclosed no relevant financial relationships.

Artificial intelligence can distinguish overlapping inflammatory conditions with total accuracy, according to a new study presented at the annual meeting of the American College of Rheumatology.

Texas pediatricians faced a conundrum during the pandemic. Endemic typhus, a flea-borne tropical infection common to the region, is nearly indistinguishable from multisystem inflammatory syndrome in children (MIS-C), a rare condition set in motion by SARS-CoV-2 infection. Children with either ailment had seemingly identical symptoms: fever, rash, gastrointestinal issues, and in need of swift treatment. A diagnosis of endemic typhus can take 4-6 days to confirm.

Tiphanie Vogel, MD, PhD, a pediatric rheumatologist at Texas Children’s Hospital, Houston, and colleagues sought to create a tool to hasten diagnosis and, ideally, treatment. To do so, they incorporated machine learning and clinical factors available within the first 6 hours of the onset of symptoms.

The team analyzed 49 demographic, clinical, and laboratory measures from the medical records of 133 children with MIS-C and 87 with endemic typhus. Using deep learning, they narrowed the model to 30 essential features that became the backbone of AI-MET, a two-phase clinical-decision support system.

Phase 1 uses 17 clinical factors and can be performed on paper. If a patient’s score in phase 1 is not determinative, clinicians proceed to phase 2, which uses an additional 13 weighted factors and machine learning.

In testing, the two-part tool classified each of the 220 test patients perfectly. And it diagnosed a second group of 111 patients with MIS-C with 99% (110/111) accuracy.

Of note, “that first step classifies [a patient] correctly half of the time,” Dr. Vogel said, so the second, AI phase of the tool was necessary for only half of cases. Dr. Vogel said that’s a good sign; it means that the tool is useful in settings where AI may not always be feasible, like in a busy ED.

Melissa Mizesko, MD, a pediatric rheumatologist at Driscoll Children’s Hospital in Corpus Christi, Tex., said that the new tool could help clinicians streamline care. When cases of MIS-C peaked in Texas, clinicians often would start sick children on doxycycline and treat for MIS-C at the same time, then wait to see whether the antibiotic brought the fever down.

“This [new tool] is helpful if you live in a part of the country that has typhus,” said Jane Burns, MD, director of the Kawasaki Disease Research Center at the University of California, San Diego, who helped develop a similar AI-based tool to distinguish MIS-C from Kawasaki disease. But she encouraged the researchers to expand their testing to include other conditions. Although the AI model Dr. Vogel’s group developed can pinpoint MIS-C or endemic typhus, what if a child has neither condition? “It’s not often you’re dealing with a diagnosis between just two specific diseases,” Dr. Burns said.

Dr. Vogel is also interested in making AI-MET more efficient. “This go-round we prioritized perfect accuracy,” she said. But 30 clinical factors, with 17 of them recorded and calculated by hand, is a lot. “Could we still get this to be very accurate, maybe not perfect, with less inputs?”

In addition to refining AI-MET, which Texas Children’s eventually hopes to make available to other institutions, Dr. Vogel and associates are also considering other use cases for AI. Lupus is one option. “Maybe with machine learning we could identify clues at diagnosis that would help recommend targeted treatment,” she said

Dr. Vogel disclosed potential conflicts of interest with Moderna, Novartis, Pfizer, and SOBI. Dr. Burns and Dr. Mizesko disclosed no relevant conflicts of interest.

Artificial intelligence can distinguish overlapping inflammatory conditions with total accuracy, according to a new study presented at the annual meeting of the American College of Rheumatology.

Texas pediatricians faced a conundrum during the pandemic. Endemic typhus, a flea-borne tropical infection common to the region, is nearly indistinguishable from multisystem inflammatory syndrome in children (MIS-C), a rare condition set in motion by SARS-CoV-2 infection. Children with either ailment had seemingly identical symptoms: fever, rash, gastrointestinal issues, and in need of swift treatment. A diagnosis of endemic typhus can take 4-6 days to confirm.

Tiphanie Vogel, MD, PhD, a pediatric rheumatologist at Texas Children’s Hospital, Houston, and colleagues sought to create a tool to hasten diagnosis and, ideally, treatment. To do so, they incorporated machine learning and clinical factors available within the first 6 hours of the onset of symptoms.

The team analyzed 49 demographic, clinical, and laboratory measures from the medical records of 133 children with MIS-C and 87 with endemic typhus. Using deep learning, they narrowed the model to 30 essential features that became the backbone of AI-MET, a two-phase clinical-decision support system.

Long COVID can exacerbate existing mental health disorders or cause new-onset psychiatric symptoms, but mental illness does not cause long COVID, experts say.

The consensus guidance statement on the assessment and treatment of mental health symptoms in patients with post-acute sequelae of SARS-CoV-2 infection (PASC), also known as long COVID, was published online in Physical Medicine and Rehabilitation, the journal of the American Academy of Physical Medicine and Rehabilitation (AAPM&R).

The statement was developed by a task force that included experts from physical medicine, neurology, neuropsychiatry, neuropsychology, rehabilitation psychology, and primary care. It is the eighth guidance statement on long COVID published by AAPM&R).

“Many of our patients have reported experiences in which their symptoms of long COVID have been dismissed either by loved ones in the community, or also amongst health care providers, and they’ve been told their symptoms are in their head or due to a mental health condition, but that’s simply not true,” Abby L. Cheng, MD, a physiatrist at Barnes Jewish Hospital in St. Louis and a coauthor of the new guidance, said in a press briefing.

“Long COVID is real, and mental health conditions do not cause long COVID,” Dr. Cheng added.
 

Millions of Americans affected

Anxiety and depression have been reported as the second and third most common symptoms of long COVID, according to the guidance statement.

There is some evidence that the body’s inflammatory response – specifically, circulating cytokines – may contribute to the worsening of mental health symptoms or may bring on new symptoms of anxiety or depression, said Dr. Cheng. Cytokines may also affect levels of brain chemicals, such as serotonin, she said.

Researchers are also exploring whether the persistence of virus in the body, miniature blood clots in the body and brain, and changes to the gut microbiome affect the mental health of people with long COVID.

Some mental health symptoms – such as fatigue, brain fog, sleep disturbances, and tachycardia – can mimic long COVID symptoms, said Dr. Cheng.

The treatment is the same for someone with or without long COVID who has anxiety, depression, posttraumatic stress disorder, or other mental health conditions and includes treatment of coexisting medical conditions, supportive therapy and cognitive-behavioral therapy, and pharmacologic interventions, she said.

“Group therapy may have a particular role in the long COVID population because it really provides that social connection and awareness of additional resources in addition to validation of their experiences,” Dr. Cheng said.

The guidance suggests that primary care practitioners – if it’s within their comfort zone and they have the training – can be the first line for managing mental health symptoms.

But for patients whose symptoms are interfering with functioning and their ability to interact with the community, the guidance urges primary care clinicians to refer the patient to a specialist.

“It leaves the door open to them to practice within their scope but also gives guidance as to how, why, and who should be referred to the next level of care,” said Dr. Cheng.

Coauthor Monica Verduzco-Gutierrez, MD, chair of rehabilitation medicine at UT Health San Antonio, Texas, said that although fewer people are now getting long COVID, “it’s still an impactful number.”

The Centers for Disease Control and Prevention recently estimated that about 7% of American adults (18 million) and 1.3% of children had experienced long COVID.

Dr. Gutierrez said that it’s an evolving number, as some patients who have a second or third or fourth SARS-CoV-2 infection experience exacerbations of previous bouts of long COVID or develop long COVID for the first time.

“We are still getting new patients on a regular basis with long COVID,” said AAPM&R President Steven R. Flanagan, MD, a physical medicine specialist.

“This is a problem that really is not going away. It is still real and still ever-present,” said Dr. Flanagan, chair of rehabilitation medicine at NYU Langone Health.

Good news for people struggling with sensory problems after a bout of COVID-19. Although mild cases of the disease often impair the ability to taste and smell, and the problem can drag on for months, a new study from Italy shows that most people return to their senses, as it were, within 3 years.

“In the vast majority of cases, the loss of the sense of smell is not irreversible,” said Paolo Boscolo-Rizzo, MD, a professor of medicine, surgery, and health sciences at the University of Trieste (Italy), and a co-author of the study, published as a research letter in JAMA Otolaryngology–Head & Neck Surgery.

Dr. Boscolo-Rizzo and his colleagues analyzed data from 88 adults with mild COVID-19, which was defined as having no lower respiratory disease and blood oxygen saturation of 94% or greater. Another group of 88 adults who never contracted the virus but sometimes had difficulties with smell and taste were also studied. In both groups, the average age was 49 years, all participants were White, and 58% were women.

The researchers tested participants’ sense of smell with sticks that contained different odors and checked their sense of taste with strips that had different tastes. Over time, fewer people had difficulty distinguishing odors. Three years after developing COVID-19, only 12 people had impaired smell, compared with 36 people at year 1 and 24 people at year 2. And at the 3-year mark, all participants had at least a partial ability to smell. 

The story was similar with sense of taste, with 10 of 88 people reporting impairments 3 years later. By then, people with COVID-19 were no more likely to have trouble with smell or taste than people who did not get the virus. 

A study this past June showed a strong correlation between severity of COVID-19 symptoms and impaired sense of taste and smell and estimated that millions of Americans maintained altered senses. More than 10% of people in the Italian study still had trouble with smell or taste 3 years later.
 

Emerging treatments, psychological concerns

“We’re seeing fewer people with this problem, but there are still people suffering from it,” said Fernando Carnavali, MD, an internal medicine physician and a site director for the Center for Post-COVID Care at the Icahn School of Medicine at Mount Sinai, New York City.

Dr. Carnavali wasn’t part of this study, but he did find the new results encouraging, and he called for similar studies in diverse populations that have experienced COVID-19. He also noted that an impaired sense of smell is distressing.

“It really has a significant psychological impact,” Dr. Carnavali said.

He recalled a patient crying in his office because her inability to smell made it impossible for her to cook. Dr. Carnavali recommended clinicians refer patients facing protracted loss of smell or taste to mental health professionals for support.

Treatments are emerging for COVID-19 smell loss. One approach is to inject platelet-rich plasma into a patient’s nasal cavities to help neurons related to smell repair themselves.

A randomized trial showed platelet-rich plasma significantly outperformed placebo in patients with smell loss up to a year after getting COVID-19.

“I wish more people would do it,” said Zara Patel, MD, an otolaryngologist at Stanford (Calif.) Medicine, who helped conduct that trial. She said some physicians may be nervous about injecting plasma so close to the skull and are therefore hesitant to try this approach. 

Another technique may help to address the olfactory condition known as parosmia, in which patients generally experience a benign odor as rancid, according to otolaryngologist Nyssa Farrell, MD, of Washington University School of Medicine, St. Louis. Dr. Farrell said around two-thirds of patients who contract COVID-19 develop the condition, and the rates of long-term parosmia range from 10%-50% depending on various studies.

“It is almost always foul; this can profoundly affect someone’s quality of life,” impairing their ability to eat or to be intimate with a partner who now smells unpleasant, said Dr. Farrell, who wasn’t associated with this research.

The treatment, called a stellate ganglion block, is provided through a shot into nerves in the neck. People with parosmia associated with COVID-19 often report that this method cures them. Dr. Patel said that may be because their psychological health is improving, not their sense of smell, because the area of the body where the stellate ganglion block is applied is not part of the olfactory system.

Earlier this year, Dr. Farrell and colleagues reported that parosmia linked to COVID-19 is associated with an increased risk for depression, anxiety, and suicidal ideation. 

One coauthor reported receiving grants from Smell and Taste Lab, Takasago, Baia Foods, and Frequency Therapeutics. The other authors reported no relevant financial relationships.

Earlier this year, Dr. Farrell and colleagues reported that parosmia linked to COVID-19 is associated with an increased risk for depression, anxiety, and suicidal ideation. 

One coauthor reported receiving grants from Smell and Taste Lab, Takasago, Baia Foods, and Frequency Therapeutics. The other authors reported no relevant financial relationships.

People infected multiple times with COVID-19 are more likely to develop long COVID, and most never fully recover from the condition. Those are two of the most striking findings of a comprehensive new research study of 138,000 veterans.

Lead researcher Ziyad Al-Aly, MD, chief of research at Veterans Affairs St. Louis Health Care and clinical epidemiologist at Washington University in St. Louis, spoke with this news organization about his team’s findings, what we know – and don’t – about long COVID, and what it means for physicians treating patients with the condition.

Excerpts of the interview follow.

Your research concluded that for those infected early in the pandemic, some long COVID symptoms declined over 2 years, but some did not. You have also concluded that long COVID is a chronic disease. Why?

We’ve been in this journey a little bit more than three and a half years. Some patients do experience some recovery. But that’s not the norm. Most people do not really fully recover. The health trajectory for people with long COVID is really very heterogeneous. There is no one-size-fits-all. There’s really no one line that I could give you that could cover all your patients. But it is very, very, very clear that a bunch of them experienced long COVID for sure; that’s really happening.

It happened in the pre-Delta era and in the Delta era, and with Omicron subvariants, even now. There are people who think, “This is a nothing-burger anymore,” or “It’s not an issue anymore.” It’s still happening with the current variants. Vaccines do reduce risk for long COVID, but do not completely eliminate the risk for long COVID.

You work with patients with long COVID in the clinic and also analyze data from thousands more. If long COVID does not go away, what should doctors look for in everyday practice that will help them recognize and help patients with long COVID?

Long COVID is not uncommon. We see it in the clinic in large numbers. Whatever clinic you’re running – if you’re running a cardiology clinic, or a nephrology clinic, or diabetes, or primary care – probably some of your people have it. You may not know about it. They may not tell you about it. You may not recognize it.

Not all long COVID is the same, and that’s really what makes it complex and makes it really hard to deal with in the clinic. But that’s the reality that we’re all dealing with. And it’s multisystemic; it’s not like it affects the heart only, the brain only, or the autonomic nervous system only. It does not behave in the same way in different individuals – they may have different manifestations, various health trajectories, and different outcomes. It’s important for doctors to get up to speed on long COVID as a multisystem illness.

Management at this point is really managing the symptoms. We don’t have a treatment for it; we don’t have a cure for it.

Some patients experience what you’ve described as partial recovery. What does that look like?

Some individuals do experience some recovery over time, but for most individuals, the recovery is long and arduous. Long COVID can last with them for many years. Some people may come back to the clinic and say, “I’m doing better,” but if you really flesh it out and dig deeper, they didn’t do better; they adjusted to a new baseline. They used to walk the dog three to four blocks, and now they walk the dog only half a block. They used to do an activity with their partner every Saturday or Sunday, and now they do half of that.

If you’re a physician, a primary care provider, or any other provider who is dealing with a patient with long COVID, know that this is really happening. It can happen even in vaccinated individuals. The presentation is heterogeneous. Some people may present to you with and say. “Well, before I had COVID I was mentally sharp and now having I’m having difficulty with memory, etc.” It can sometimes present as fatigue or postexertional malaise.

In some instances, it can present as sleep problems. It can present as what we call postural orthostatic tachycardia syndrome (POTS). Those people get a significant increase in heart rate with postural changes.

What the most important thing we can we learn from the emergence of long COVID?

This whole thing taught us that infections can cause chronic disease. That’s really the No. 1 lesson that I take from this pandemic – that infections can cause chronic disease.

Looking at only acute illness from COVID is really only looking at the tip of the iceberg. Beneath that tip of the iceberg lies this hidden toll of disease that we don’t really talk about that much.

This pandemic shone a very, very good light on the idea that there is really an intimate connection between infections and chronic disease. It was really hardwired into our medical training as doctors that most infections, when people get over the hump of the acute phase of the disease, it’s all behind them. I think long COVID has humbled us in many, many ways, but chief among those is the realization – the stark realization – that infections can cause chronic disease.

That’s really going back to your [first] question: What does it mean that some people are not recovering? They actually have chronic illness. I’m hoping that we will find a treatment, that we’ll start finding things that would help them get back to baseline. But at this point in time, what we’re dealing with is people with chronic illness or chronic disease that may continue to affect them for many years to come in the absence of a treatment or a cure.

A pair of new studies published about long COVID have shed more light on the sometimes-disabling condition that affects millions of people in the United States. 

Scientists worldwide have been working to understand the wide-ranging condition, from risk factors to causes to potential treatments. 

In the first study, 31 adults underwent lumbar puncture and blood draws to look for changes in their immune systems and also to look for changes in the nerve cells that could affect transmission of signals to the brain.

Among the participants, 25 people had neurocognitive symptoms of long COVID, such as memory loss or attention problems. Six participants had fully recovered from COVID, and 17 people had never had COVID. 

Those who had COVID were diagnosed between March 2020 and May 2021. Their fluid samples were drawn at least three months after their first symptoms.

The results were published in the Journal of Infectious Diseases. Study results showed that long COVID does not appear to be linked to the SARS-CoV-2 virus invading the brain or causing active brain damage.

According to a summary of the study from the University of Gothenburg (Sweden), where the researchers work, “there were no significant differences between the groups when analyzing blood and cerebrospinal fluid for immune activation or brain injury markers. The findings thus suggest that post-COVID condition is not the result of ongoing infection, immune activation, or brain damage.”

In the second study, Norwegian researchers compared the likelihood of having 17 different long COVID symptoms based on whether a person had been infected with COVID. The analysis included 53,846 people who were diagnosed with COVID between February 2020 and February 2021, as well as more than 485,000 people who were not infected. Most people had not been vaccinated against COVID-19 during the time of the study.

The results were published in the journal BMC Infectious Diseases. Study results showed that people who had COVID were more than twice as likely to experience shortness of breath or fatigue. They were also more likely to experience memory loss or headache compared to people who never had COVID. Researchers only looked at symptoms that occurred at least three months after a COVID diagnosis.

They also found that hospitalization increased the risk for experiencing long COVID symptoms of shortness of breath, fatigue, and memory loss.

The authors noted that a limitation of their study was that, often, not all symptoms reported during a visit with a general practice medical provider are recorded in Norway, which could have affected the results.

Health care providers who give this year’s Moderna COVID-19 vaccine to children aged 6 months to 11 years should be sure they withdraw the correct volume of the vaccine from the vial to ensure a proper dose, the Food and Drug Administration said in a MedWatch issued Nov. 1, 2023.

That dose is 0.25 mL for children 6 months through 11 years. In the MedWatch, the FDA said that it “has become aware” that the single-dose vial for use in this age group “contains notably more than 0.25 mL of the vaccine.” It added: “Some healthcare providers may be withdrawing the entire contents of the vial to administer to an individual.”

The FDA revised the Fact Sheet for Healthcare Providers Administering Vaccine to clarify that the 0.25 mL should be withdrawn from the vial and that the vial and any excess then should be discarded. It is in a single-dose vial with a blue cap and a green label.

“It is common [for vaccine makers] to put in a little bit of extra vaccine just to make sure everyone gets enough,” said William Schaffner, MD, an infectious disease specialist at Vanderbilt University Medical Center, Nashville, Tenn. “The provider is supposed to be looking at the syringe when they withdraw it to make sure they get the right amount,” Dr. Schaffner said.

Recently, parents on social media had expressed concerns that their children may have gotten more than the recommended dose, with some parents noticing more reactions such as soreness and fever with the 2023-2024 vaccine dose than they did with their children’s previous COVID vaccinations.

“Since the beginning of the rollout, parents were telling us of cases where pharmacies accidentally gave their children a double dose, while doctors in our group were pointing out that their vials for children contained twice the amount than what was needed,” said Fatima Khan, a parent and cofounder of the group Protect Their Future, an organization that advocates for pediatric vaccine access. Members contacted the FDA and other officials. “We appreciate that the FDA took our concerns seriously and issued this safety update,” Ms. Khan said.

A spokesperson for Moderna is researching how much more vaccine the single-dose vials might contain.
 

No safety risks identified

“The FDA has not identified any safety risks associated with administration of the higher dose in individuals 6 months through 11 years of age and no serious adverse events were identified related to a dosing error for the vaccine,” Cherie Duvall-Jones, an FDA spokesperson, said in an email response.

“The FDA received questions from stakeholders about the dosing issue on Oct. 29, and contacted Moderna to discuss and better understand the issue,” Ms. Duvall-Jones said. The agency then alerted health care providers via the safety communication and other means to be sure the correct dosage is given to the children aged 12 years or younger.
 

One parent’s experience

Jane Jih, MD, an internist in San Francisco, took her 7-year-old daughter to a pharmacy to get the vaccine, and it was the first time the pharmacist had given a pediatric dose. “We both had to double check the dose,” Dr. Jih said. She observed that the vial had about 0.40 mL, which is 0.15 mL above the recommended dose.

A few weeks later, Dr. Jih could access the vaccine for her nearly-3-year-old son. The nurse practitioner who administered it had been giving many pediatric Moderna shots, she said, “so I felt more confident in the second scenario.”
 

Perhaps more reactions, no danger

“If you get a little bit more [than the recommended 0.25 mL], that certainly is not going to harm the child,” Dr. Schaffner said. “There may be a little bit more local reaction. In terms of the child’s immune system, there really isn’t any harm.”

If an entire adult dose is mistakenly given, he said, “I think the reaction locally in some children may be more evident, they may get more sore arms, redness, maybe a little bit more swelling and tenderness. Fever is also a possibility, but “these vaccines have not been associated with too much fever.”

Could a double dose do more harm than that? “It is unknown,” said Aaron Glatt, MD, chief of infectious diseases and hospital epidemiologist for Mount Sinai South Nassau, Oceanside, N.Y. “But there is the theoretical potential for some more complications. I do not know whether this [excess vaccine] would cause an increased likelihood of cardiac inflammatory problems like myocarditis or other rare complications to occur more frequently.”

The message for health care providers giving the vaccine, Dr. Schaffner said, is: “Look at your syringe to make sure the dose is appropriate.”

“Since the beginning of the rollout, parents were telling us of cases where pharmacies accidentally gave their children a double dose, while doctors in our group were pointing out that their vials for children contained twice the amount than what was needed,” said Fatima Khan, a parent and cofounder of the group Protect Their Future, an organization that advocates for pediatric vaccine access. Members contacted the FDA and other officials. “We appreciate that the FDA took our concerns seriously and issued this safety update,” Ms. Khan said.

A spokesperson for Moderna is researching how much more vaccine the single-dose vials might contain.
 

No safety risks identified

“The FDA has not identified any safety risks associated with administration of the higher dose in individuals 6 months through 11 years of age and no serious adverse events were identified related to a dosing error for the vaccine,” Cherie Duvall-Jones, an FDA spokesperson, said in an email response.

“The FDA received questions from stakeholders about the dosing issue on Oct. 29, and contacted Moderna to discuss and better understand the issue,” Ms. Duvall-Jones said. The agency then alerted health care providers via the safety communication and other means to be sure the correct dosage is given to the children aged 12 years or younger.
 

One parent’s experience

Jane Jih, MD, an internist in San Francisco, took her 7-year-old daughter to a pharmacy to get the vaccine, and it was the first time the pharmacist had given a pediatric dose. “We both had to double check the dose,” Dr. Jih said. She observed that the vial had about 0.40 mL, which is 0.15 mL above the recommended dose.

A few weeks later, Dr. Jih could access the vaccine for her nearly-3-year-old son. The nurse practitioner who administered it had been giving many pediatric Moderna shots, she said, “so I felt more confident in the second scenario.”
 

Perhaps more reactions, no danger

“If you get a little bit more [than the recommended 0.25 mL], that certainly is not going to harm the child,” Dr. Schaffner said. “There may be a little bit more local reaction. In terms of the child’s immune system, there really isn’t any harm.”

If an entire adult dose is mistakenly given, he said, “I think the reaction locally in some children may be more evident, they may get more sore arms, redness, maybe a little bit more swelling and tenderness. Fever is also a possibility, but “these vaccines have not been associated with too much fever.”

Could a double dose do more harm than that? “It is unknown,” said Aaron Glatt, MD, chief of infectious diseases and hospital epidemiologist for Mount Sinai South Nassau, Oceanside, N.Y. “But there is the theoretical potential for some more complications. I do not know whether this [excess vaccine] would cause an increased likelihood of cardiac inflammatory problems like myocarditis or other rare complications to occur more frequently.”

The message for health care providers giving the vaccine, Dr. Schaffner said, is: “Look at your syringe to make sure the dose is appropriate.”

TOPLINE:

Severe mental illness (SMI) has been linked to a 50% increased risk for all-cause mortality risk after COVID-19, a large population-based study suggests.

METHODOLOGY:

• Investigators analyzed data from the Clinical Practice Research Datalink database, which contains health information on 13.5 million patients receiving care from family practices in England and Northern Ireland.
• The study included participants with SMI, including schizophrenia, schizoaffective disorder, and bipolar disorder.
• Participants were aged 5 years or older with a SARS-CoV-2 infection recorded between Feb. 1, 2020, and March 31, 2021, spanning two waves of the pandemic.
• Death rates among participants with SMI and COVID-19 (n = 7,150; 56% female) were compared with those in a control group of participants without SMI who had been diagnosed with COVID-19 (n = 650,000; 55% female).

TAKEAWAY:

• Participants with SMI and COVID-19 had a 53% higher risk for death than those in the non-SMI control group (adjusted hazard ratio, 1.53; 95% confidence interval, 1.39-1.68).
• Black Caribbean/Black African participants were more likely than White participants to die of COVID-19 (aHR, 1.22; 95% CI, 1.12-1.34), although ethnicity was not recorded in 30% of participants.
• After SARS-CoV-2 infection, for every additional multimorbid condition, the aHR for death increased by 6% in the SMI group and 16% in the non-SMI group (P = .001). Some of these conditions included hypertension, heart disease, diabetes, kidney disease, depression, and anxiety.

IN PRACTICE:

“From a public health perspective, our study has emphasized the need for early and timely preventative interventions (e.g. vaccination) for the SMI population. Future studies are needed to disentangle the complex biological and psychosocial factors, and health care pathways, that have led to the greater mortality rates in the SMI population,” the authors write.

Jayati Das-Munshi, MD, of Kings College London, led the study, which was published online in the British Journal of Psychiatry. The study was funded by the Health Foundation.

LIMITATIONS:

COVID-19 may have been underdiagnosed or underreported in the records studied. Also, investigators did not have information about cause of death.

DISCLOSURES:

One author received funding from Janssen, GSK, and Takeda. All other authors declared no conflicts of interest.
