COVID-19 Updates

The Omicron decline continued for a fourth consecutive week as new cases of COVID-19 in children fell by 42% from the week before, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.

That 42% represents a drop from the 299,000 new cases reported for Feb. 4-10 down to 174,000 for the most recent week, Feb. 11-17. In the last 4 weeks, the United States has seen new child cases drop 85% from a pandemic-high 1.15 million in mid-January, the AAP and CHA said in their weekly COVID-19 report.

The overall count of COVID-19 cases in children is 12.5 million over the course of the pandemic, and that represents 19% of cases reported among all ages, the AAP and CHA said based on data collected from 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.

Hospital admissions also continued to fall, with the rate for children aged 0-17 at 0.43 per 100,000 population as of Feb. 20, down by almost 66% from the peak of 1.25 per 100,000 reached on Jan. 16, the Centers for Disease Control and Prevention reported.

A snapshot of the hospitalization situation shows that 1,687 children were occupying inpatient beds on Feb. 16, compared with 4,070 on Jan. 19, which appears to be the peak of the Omicron surge, according to data from the Department of Health & Human Services.

The state with the highest rate – 5.6 per 100,000 children – on Feb. 16 was North Dakota, although the District of Columbia came in at 11.0 per 100,000. They were followed by Oklahoma (5.3), Missouri (5.2), and West Virginia (4.1). There were three states – New Hampshire, Rhode Island, and Utah – with no children in the hospital on that date, the HHS said.

New vaccinations in children aged 5-11 years, which declined in mid- and late January, even as Omicron surged, continued to decline, as did vaccine completions. Vaccinations also fell among children aged 12-17 for the latest reporting week, Feb. 10-16, the AAP said in a separate report.

As more states and school districts drop mask mandates, data from the CDC indicate that 32.5% of 5- to 11-year olds and 67.4% of 12- to 17-year-olds have gotten at least one dose of the COVID-19 vaccine and that 25.1% and 57.3%, respectively, are fully vaccinated. Meanwhile, 20.5% of those fully vaccinated 12- to 17-year-olds have gotten a booster dose, the CDC said.

Updated guidance for health care providers on multisystem inflammatory syndrome in children (MIS-C) recognizes the evolving nature of the disease and offers strategies for pediatric rheumatologists, who also may be asked to recommend treatment for hyperinflammation in children with acute COVID-19.

Guidance is needed for many reasons, including the variable case definitions for MIS-C, the presence of MIS-C features in other infections and childhood rheumatic diseases, the extrapolation of treatment strategies from other conditions with similar presentations, and the issue of myocardial dysfunction, wrote Lauren A. Henderson, MD, MMSC, of Boston Children’s Hospital, and members of the American College of Rheumatology MIS-C and COVID-19–Related Hyperinflammation Task Force.

However, “modifications to treatment plans, particularly in patients with complex conditions, are highly disease, patient, geography, and time specific, and therefore must be individualized as part of a shared decision-making process,” the authors said. The updated guidance was published in Arthritis & Rheumatology.
 

Update needed in wake of Omicron

“We continue to see cases of MIS-C across the United States due to the spike in SARS-CoV-2 infections from the Omicron variant,” and therefore updated guidance is important at this time, Dr. Henderson told this news organization.

“MIS-C remains a serious complication of COVID-19 in children and the ACR wanted to continue to provide pediatricians with up-to-date recommendations for the management of MIS-C,” she said.

“Children began to present with MIS-C in April 2020. At that time, little was known about this entity. Most of the recommendations in the first version of the MIS-C guidance were based on expert opinion,” she explained. However, “over the last 2 years, pediatricians have worked very hard to conduct high-quality research studies to better understand MIS-C, so we now have more scientific evidence to guide our recommendations.

“In version three of the MIS-C guidance, there are new recommendations on treatment. Previously, it was unclear what medications should be used for first-line treatment in patients with MIS-C. Some children were given intravenous immunoglobulin while others were given IVIg and steroids together. Several new studies show that children with MIS-C who are treated with a combination of IVIg and steroids have better outcomes. Accordingly, the MIS-C guidance now recommends dual therapy with IVIg and steroids in children with MIS-C.”

Diagnostic evaluation

The guidance calls for maintaining a broad differential diagnosis of MIS-C, given that the condition remains rare, and that most children with COVID-19 present with mild symptoms and have excellent outcomes, the authors noted. The range of clinical features associated with MIS-C include fever, mucocutaneous findings, myocardial dysfunction, cardiac conduction abnormalities, shock, gastrointestinal symptoms, and lymphadenopathy.

Some patients also experience neurologic involvement in the form of severe headache, altered mental status, seizures, cranial nerve palsies, meningismus, cerebral edema, and ischemic or hemorrhagic stroke. Given the nonspecific nature of these symptoms, “it is imperative that a diagnostic evaluation for MIS-C include investigation for other possible causes, as deemed appropriate by the treating provider,” the authors emphasized. Other diagnostic considerations include the prevalence and chronology of COVID-19 in the community, which may change over time.
 

MIS-C and Kawasaki disease phenotypes

Earlier in the pandemic, when MIS-C first emerged, it was compared with Kawasaki disease (KD). “However, a closer examination of the literature shows that only about one-quarter to half of patients with a reported diagnosis of MIS-C meet the full diagnostic criteria for KD,” the authors wrote. Key features that separate MIS-C from KD include the greater incidence of KD among children in Japan and East Asia versus the higher incidence of MIS-C among non-Hispanic Black children. In addition, children with MIS-C have shown a wider age range, more prominent gastrointestinal and neurologic symptoms, and more frequent cardiac dysfunction, compared with those with KD.

Cardiac management

Close follow-up with cardiology is essential for children with MIS-C, according to the authors. The recommendations call for repeat echocardiograms for all children with MIS-C at a minimum of 7-14 days, then again at 4-6 weeks after the initial presentation. The authors also recommended additional echocardiograms for children with left ventricular dysfunction and cardiac aortic aneurysms. 

MIS-C treatment

Current treatment recommendations emphasize that patients under investigation for MIS-C with life-threatening manifestations may need immunomodulatory therapy before a full diagnostic evaluation is complete, the authors said. However, patients without life-threatening manifestations should be evaluated before starting immunomodulatory treatment to avoid potentially harmful therapies for pediatric patients who don’t need them.

When MIS-C is refractory to initial immunomodulatory treatment, a second dose of IVIg is not recommended, but intensification therapy is advised with either high-dose (10-30 mg/kg per day) glucocorticoids, anakinra, or infliximab. However, there is little evidence available for selecting a specific agent for intensification therapy.

The task force also advises giving low-dose aspirin (3-5 mg/kg per day, up to 81 mg once daily) to all MIS-C patients without active bleeding or significant bleeding risk until normalization of the platelet count and confirmed normal coronary arteries at least 4 weeks after diagnosis.
 

COVID-19 and hyperinflammation

The task force also noted a distinction between MIS-C and severe COVID-19 in children. Although many children with MIS-C are previously healthy, most children who develop severe COVID-19 during an initial infection have complex conditions or comorbidities such as developmental delay or genetic anomaly, or chronic conditions such as congenital heart disease, type 1 diabetes, or asthma, the authors said. They recommend that “hospitalized children with COVID-19 requiring supplemental oxygen or respiratory support should be considered for immunomodulatory therapy in addition to supportive care and antiviral medications.”

The authors acknowledged the limitations and evolving nature of the recommendations, which will continue to change and do not replace clinical judgment for the management of individual patients. In the meantime, the ACR will support the task force in reviewing new evidence and providing revised versions of the current document.

Many questions about MIS-C remain, Dr. Henderson said in an interview. “It can be very hard to diagnose children with MIS-C because many of the symptoms are similar to those seen in other febrile illness of childhood. We need to identify better biomarkers to help us make the diagnosis of MIS-C. In addition, we need studies to provide information about what treatments should be used if children fail to respond to IVIg and steroids. Finally, it appears that vaccination [against SARS-CoV-2] protects against severe forms of MIS-C, and studies are needed to see how vaccination protects children from MIS-C.”

The development of the guidance was supported by the American College of Rheumatology. Dr. Henderson disclosed relationships with companies including Sobi, Pfizer, and Adaptive Biotechnologies (less than $10,000) and research support from the Childhood Arthritis and Rheumatology Research Alliance and research grant support from Bristol-Myers Squibb.

The Omicron subvariant, BA.2, is not only more transmissible than the original Omicron strain, BA.1, but may cause more severe disease, a lab study from Japan says.

“Our multiscale investigations suggest that the risk of BA.2 for global health is potentially higher than that of BA.1,” the researchers said in the study published on the preprint server bioRxiv. The study has not been peer-reviewed.

The researchers infected hamsters with BA.1 and BA.2. The hamsters infected with BA.2 got sicker, with more lung damage and loss of body weight. Results were similar when mice were infected with BA.1 and BA.2.

“Infection experiments using hamsters show that BA.2 is more pathogenic than BA.1,” the study said.

BA.1 and BA.2 both appear to evade immunity created by COVID-19 vaccines, the study said. But a booster shot makes illness after infection 74% less likely, CNN said.

What’s more, therapeutic monoclonal antibodies used to treat people infected with COVID didn’t have much effect on BA.2. 

BA.2 was “almost completely resistant” to casirivimab and imdevimab and was 35 times more resistant to sotrovimab, compared to the original B.1.1 virus, the researchers wrote. 

“In summary, our data suggest the possibility that BA.2 would be the most concerned variant to global health,” the researchers wrote. “Currently, both BA.2 and BA.1 are recognised together as Omicron and these are almost undistinguishable. Based on our findings, we propose that BA.2 should be recognised as a unique variant of concern, and this SARS-CoV-2 variant should be monitored in depth.”

If the World Health Organization recognized BA.2 as a “unique variant of concern,” it would be given its own Greek letter.

But some scientists noted that findings in the lab don’t always reflect what’s happening in the real world of people.

“I think it’s always hard to translate differences in animal and cell culture models to what’s going on with regards to human disease,” Jeremy Kamil, PhD, an associate professor of microbiology and immunology at Louisiana State University Health Shreveport, told Newsweek. “That said, the differences do look real.”

“It might be, from a human’s perspective, a worse virus than BA.1 and might be able to transmit better and cause worse disease,” Daniel Rhoads, MD, section head of microbiology at the Cleveland Clinic in Ohio, told CNN. He reviewed the Japanese study but was not involved in it.

Another scientist who reviewed the study but was not involved in the research noted that human immune systems are evolving along with the COVID variants. 

“One of the caveats that we have to think about, as we get new variants that might seem more dangerous, is the fact that there’s two sides to the story,” Deborah Fuller, PhD, a virologist at the University of Washington School of Medicine, told CNN. “Our immune system is evolving as well. And so that’s pushing back on things.”

Scientists have already established that BA.2 is more transmissible than BA.1. The Omicron subvariant has been detected in 74 countries and 47 U.S. states, according to CNN. About 4% of Americans with COVID were infected with BA.2, the outlet reported, citing the CDC, but it’s now the dominant strain in other nations.

It’s not clear yet if BA.2 causes more severe illness in people. While BA.2 spreads faster than BA.1, there’s no evidence the subvariant makes people any sicker, an official with the World Health Organization said, according to CNBC.

Based on our findings, we propose that BA.2 should be recognised as a unique variant of concern, and this SARS-CoV-2 variant should be monitored in depth.”

If the World Health Organization recognized BA.2 as a “unique variant of concern,” it would be given its own Greek letter.

But some scientists noted that findings in the lab don’t always reflect what’s happening in the real world of people.

“I think it’s always hard to translate differences in animal and cell culture models to what’s going on with regards to human disease,” Jeremy Kamil, PhD, an associate professor of microbiology and immunology at Louisiana State University Health Shreveport, told Newsweek. “That said, the differences do look real.”

“It might be, from a human’s perspective, a worse virus than BA.1 and might be able to transmit better and cause worse disease,” Daniel Rhoads, MD, section head of microbiology at the Cleveland Clinic in Ohio, told CNN. He reviewed the Japanese study but was not involved in it.

Another scientist who reviewed the study but was not involved in the research noted that human immune systems are evolving along with the COVID variants. 

“One of the caveats that we have to think about, as we get new variants that might seem more dangerous, is the fact that there’s two sides to the story,” Deborah Fuller, PhD, a virologist at the University of Washington School of Medicine, told CNN. “Our immune system is evolving as well. And so that’s pushing back on things.”

Scientists have already established that BA.2 is more transmissible than BA.1. The Omicron subvariant has been detected in 74 countries and 47 U.S. states, according to CNN. About 4% of Americans with COVID were infected with BA.2, the outlet reported, citing the CDC, but it’s now the dominant strain in other nations.

It’s not clear yet if BA.2 causes more severe illness in people. While BA.2 spreads faster than BA.1, there’s no evidence the subvariant makes people any sicker, an official with the World Health Organization said, according to CNBC.

The Omicron subvariant, BA.2, is not only more transmissible than the original Omicron strain, BA.1, but may cause more severe disease, a lab study from Japan says.

“Our multiscale investigations suggest that the risk of BA.2 for global health is potentially higher than that of BA.1,” the researchers said in the study published on the preprint server bioRxiv. The study has not been peer-reviewed.

The researchers infected hamsters with BA.1 and BA.2. The hamsters infected with BA.2 got sicker, with more lung damage and loss of body weight. Results were similar when mice were infected with BA.1 and BA.2.

“Infection experiments using hamsters show that BA.2 is more pathogenic than BA.1,” the study said.

BA.1 and BA.2 both appear to evade immunity created by COVID-19 vaccines, the study said. But a booster shot makes illness after infection 74% less likely, CNN said.

What’s more, therapeutic monoclonal antibodies used to treat people infected with COVID didn’t have much effect on BA.2.

Two features are significantly associated with a higher risk for developing long COVID symptoms among people with inflammatory bowel disease (IBD), according to a large Danish population study.

People with Crohn’s disease (CD) who experienced adverse acute COVID-19, defined as requiring hospitalization, were nearly three times more likely to report persistent symptoms 12 weeks after acute infection.

“Long-term, persisting symptoms following COVID-19 is a frequently occurring problem, which is probably underappreciated. IBD specialists should therefore be aware of any of these symptoms and actively ask patients whether they have these problems,” lead author Mohamed Attauabi, MD, PhD, said in an interview.

Dr. Attauabi and colleagues also found that people with ulcerative colitis (UC) who discontinued immunosuppressive agents because of COVID-19 were 1.5 times more likely to experience long COVID symptoms, a result that surprised the researchers.

“This has not been shown before and remains to be confirmed,” said Dr. Attauabi, a fellow in the department of gastroenterology at Herlev Hospital at the University of Copenhagen.

Attauabi presented the results as a digital oral presentation at the 17th congress of the European Crohn’s and Colitis Organisation.
 

A closer look at IBD and COVID-19

Large, hospital-based studies of symptoms consistent with long COVID reveal a high prevalence of fatigue, sleep difficulties, and anxiety at 12 weeks or more post acute infection. However, these were not specific to people with CD or UC, Dr. Attauabi said.

“In patients with IBD, the risk of long-term sequelae of COVID-19 remains to be investigated,” he said.

Dr. Attauabi and colleagues studied 197 people with CD and 319 with UC, all of whom had polymerase chain reaction–confirmed COVID-19. Participants were prospectively enrolled in the population-based Danish IBD-COVID registry from January 28, 2020 to April 1, 2021. At a median of 5.1 months, a subset of 85 people with CD and 137 with UC agreed to report any post-COVID symptoms.

Older age, smoking, IBD disease activity, and presence of comorbidities were not associated with a significantly elevated risk of long COVID.

In a multivariate analysis, hospitalization for COVID-19 among people with CD was significantly associated with long COVID (odds ratio, 2.76; 95% confidence interval, 1.05-3.90; P = .04).

Furthermore, people with UC who stopped taking immunosuppressive agents also had a significantly higher risk (OR, 1.50; 95% CI, 1.07-10.22; P = .01).

“However, IBD medications such as systemic steroids were not associated with this outcome,” Dr. Attauabi said.
 

Fatigue most common long COVID symptom

Fatigue was the most common long COVID symptom, reported by 37% of patients with CD and 36% with UC.

Anosmia and ageusia were also common, reported by 29% and 28% of patients with CD, and 27% and 19% of those with UC, respectively.

“In our cohort of patients with UC or CD who developed COVID-19, the long-term health effects of COVID-19 did not appear to differ among patients with UC or CD nor according to IBD medications,” Dr. Attauabi said.

That is a “great study,” said session cochair Torsten Kucharzik, MD, PhD, head of internal medicine and gastroenterology at Lueneburg (Germany) Hospital.

When Dr. Kucharzik asked about smoking, Dr. Attauabi responded that they collected information on current and previous smoking, but they chose not to include the data because it was not statistically significant.

Dr. Attauabi has reported no relevant financial relationships. Dr. Kucharzik has reported receiving grants from Takeda and personal fees from companies including MSD/Essex, AbbVie, Falk Foundation, Biogen, Bristol-Myers Squibb, Arena, Celgene, Celltrion, Ferring, Janssen, Galapagos, Olympus, Mundipharma, Takeda, Amgen, Pfizer, Roche, and Vifor Pharma.

Ivermectin treatment given to high-risk patients with mild-to-moderate COVID-19 during the first week of illness did not prevent progression to severe disease, according to results from a randomized clinical trial.

“The study findings do not support the use of ivermectin for patients with COVID-19,” researchers conclude in the paper published online in JAMA Internal Medicine.

The open-label trial was conducted at 20 public hospitals and a COVID-19 quarantine center in Malaysia between May 31 and Oct. 25, 2021. It was led by Steven Chee Loon Lim, MRCP, department of medicine, Raja Permaisuri Bainun Hospital, Perak, Malaysia.

Among 490 patients in the primary analysis, 52 of 241 patients (21.6%) in the ivermectin group and 43 of 249 patients (17.3%) in the control group progressed to severe disease (relative risk, 1.25; 95% confidence interval, 0.87-1.80; P = .25). All major ethnic groups in Malaysia were well represented, the researchers write.

Participants (average age 62.5 and 54.5% women) were randomly assigned 1:1 to receive either a 5-day course of oral ivermectin (0.4 mg/kg body weight daily for 5 days) plus standard of care (n = 241) or standard of care alone (n = 249). Standard of care included symptomatic therapy and monitoring for early deterioration based on clinical findings, laboratory tests, and chest imaging.
 

Secondary outcomes

Secondary outcomes included rates of mechanical ventilation, intensive care unit (ICU) admission, 28-day in-hospital mortality, and side effects.

In all the secondary outcomes, there were no significant differences between groups.

Mechanical ventilation occurred in four patients on the ivermectin protocol (1.7%) versus 10 patients in the control group (4.0%) (RR, 0.41; 95% CI, 0.13-1.30; P = .17); ICU admission occurred in six (2.4%) versus eight (3.2%) (RR, 0.78; 95% CI, 0.27-2.20; P = .79); and 28-day in-hospital death occurred in three (1.2%) versus 10 (4.0%) (RR, 0.31; 95% CI, 0.09-1.11; P = .09).

The most common adverse event was diarrhea, reported by 5.8% in the ivermectin group and 1.6% in the control group.
 

No difference by vaccine status

The researchers conducted a subgroup analysis to evaluate any differences in whether participants were vaccinated. They said that analysis was “unremarkable.”

Just more than half of participants (51.8%) were fully vaccinated, with two doses of COVID-19 vaccines. Among the fully vaccinated patients, 17.7% in the ivermectin group and 9.2% in the control group developed severe disease (RR, 1.92; 95% CI, 0.99-3.71; P = .06).

Ivermectin, an inexpensive and widely available antiparasitic drug, is prescribed to treat COVID-19 but has not been approved by the U.S. Food and Drug Administration for that purpose. Evidence-based data for or against use has been sparse.

The authors write that “although some early clinical studies suggested the potential efficacy of ivermectin in the treatment and prevention of COVID-19, these studies had methodologic weaknesses.”

Dr. Lim and colleagues point out that their findings are consistent with those of the IVERCOR-COVID19 trial, which found ivermectin ineffective in reducing hospitalization risk.

Previous randomized trials of ivermectin for COVID-19 patients that have included at least 400 patients have focused on outpatients.

In the current study, the authors note, patients were hospitalized, which allowed investigators to observe administration of ivermectin with a high adherence rate. Additionally, the researchers used clearly defined criteria for determining progression to severe disease.

Limitations of the current study include that the open-label design might lead to under-reporting of adverse events in the control group while overestimating the drug effects of ivermectin. The study was also not designed to assess the effects of ivermectin on mortality from COVID-19.

New prescriptions of hydroxychloroquine (HCQ) and ivermectin increased in 2020, driven particularly by rates in counties with the highest proportion of Republican votes in the 2020 U.S. presidential election, according to a cross-sectional study published in JAMA Internal Medicine.

“Our findings are consistent with the hypothesis that U.S. prescribing of hydroxychloroquine and ivermectin during the COVID-19 pandemic may have been influenced by political affiliation,” wrote Michael L. Barnett, MD, of the Harvard T.H. Chan School of Public Health in Boston and colleagues.
 

The researchers used data from the OptumLabs Data Warehouse to analyze commercial and Medicare Advantage medical claims from January 2019 through December 2020 for more than 18.5 million adults living in counties with at least 50 enrollees.

The Food and Drug Administration issued an emergency use authorization (EUA) for HCQ as a COVID-19 treatment on March 28, 2020, but the agency revoked the EUA 3 months later on June 15. Ivermectin never received an EUA for COVID treatment, but an in vitro study published April 3, 2020 claimed it had an antiviral effect.

The National Institutes of Health recommended against using ivermectin as a COVID-19 treatment on Aug. 1, 2020, but a few months later, on Nov. 13, a flawed clinical trial – later retracted – claimed ivermectin was 90% effective in treating COVID-19. Despite the lack of evidence for ivermectin’s efficacy, a Senate committee meeting on Dec. 8, 2020, included testimony from a physician who promoted its use.

In comparing ivermectin and HCQ prescription rates with counties’ political composition, the researchers adjusted their findings to account for differences in the counties’ racial composition and COVID-19 incidence as well as enrollees’ age, sex, insurance type, income, comorbidity burden, and home in a rural or urban area.

The results showed an average of 20 new HCQ prescriptions per 100,000 enrollees in 2019, but 2020 saw a sharp increase and drop in new HCQ prescriptions in March-April 2020, independent of counties’ breakdown of political affiliation.

“However, after June 2020, coinciding with the revocation of the U.S. Food and Drug Administration’s emergency use authorization for hydroxychloroquine, prescribing volume was significantly higher in the highest vs. lowest Republican vote share counties,” the authors report. The gradual increase from June through December 2020 averaged to 42 new prescriptions per 100,000, a 146% increase over 2019 rates that was driven largely by the 25% of counties with the highest proportion of Republican voters.

Similarly, rates of new ivermectin prescriptions in December 2020 were more than nine times higher in counties with the highest Republican vote share, compared with new prescriptions throughout 2019.

New prescriptions of hydroxychloroquine (HCQ) and ivermectin increased in 2020, driven particularly by rates in counties with the highest proportion of Republican votes in the 2020 U.S. presidential election, according to a cross-sectional study published in JAMA Internal Medicine.

“Our findings are consistent with the hypothesis that U.S. prescribing of hydroxychloroquine and ivermectin during the COVID-19 pandemic may have been influenced by political affiliation,” wrote Michael L. Barnett, MD, of the Harvard T.H. Chan School of Public Health in Boston and colleagues.
 

The researchers used data from the OptumLabs Data Warehouse to analyze commercial and Medicare Advantage medical claims from January 2019 through December 2020 for more than 18.5 million adults living in counties with at least 50 enrollees.

The Food and Drug Administration issued an emergency use authorization (EUA) for HCQ as a COVID-19 treatment on March 28, 2020, but the agency revoked the EUA 3 months later on June 15. Ivermectin never received an EUA for COVID treatment, but an in vitro study published April 3, 2020 claimed it had an antiviral effect.

The National Institutes of Health recommended against using ivermectin as a COVID-19 treatment on Aug. 1, 2020, but a few months later, on Nov. 13, a flawed clinical trial – later retracted – claimed ivermectin was 90% effective in treating COVID-19. Despite the lack of evidence for ivermectin’s efficacy, a Senate committee meeting on Dec. 8, 2020, included testimony from a physician who promoted its use.

In comparing ivermectin and HCQ prescription rates with counties’ political composition, the researchers adjusted their findings to account for differences in the counties’ racial composition and COVID-19 incidence as well as enrollees’ age, sex, insurance type, income, comorbidity burden, and home in a rural or urban area.

The results showed an average of 20 new HCQ prescriptions per 100,000 enrollees in 2019, but 2020 saw a sharp increase and drop in new HCQ prescriptions in March-April 2020, independent of counties’ breakdown of political affiliation.

“However, after June 2020, coinciding with the revocation of the U.S. Food and Drug Administration’s emergency use authorization for hydroxychloroquine, prescribing volume was significantly higher in the highest vs. lowest Republican vote share counties,” the authors report. The gradual increase from June through December 2020 averaged to 42 new prescriptions per 100,000, a 146% increase over 2019 rates that was driven largely by the 25% of counties with the highest proportion of Republican voters.

Similarly, rates of new ivermectin prescriptions in December 2020 were more than nine times higher in counties with the highest Republican vote share, compared with new prescriptions throughout 2019. The researchers found no differences in new prescriptions for methotrexate or albendazole in 2020 based on counties’ proportion of Republican votes.

Loss of smell. Fatigue. Mental health challenges. Difficulty breathing and other lower respiratory diseases. Fluid and electrolyte disorders. Cardiac dysrhythmia and other nonspecific chest pains. Trouble with urination. Diabetes?

Statistically, these are the conditions that defined post-acute SARS-CoV-2 (PASC) infection, or long COVID, for 28,118 people who tested positive for SARS-CoV-2 by PCR before the Omicron wave. The data, presented at the Conference on Retroviruses and Opportunistic Infections, can be used to guide diagnoses of long COVID, and may be the guide soon at Kaiser Permanente offices, Michael Horberg, MD, executive director of research, community benefit, and Medicaid strategy at the Mid-Atlantic Permanente Research Institute, said in an interview.

About one in four people who’d had COVID reported symptoms they thought might be long COVID, but through the analysis, they found that only 13% actually developed new conditions that could be categorized as long COVID.

“When you start controlling for all those chronic conditions, a lot of symptoms fall out,” Dr. Horberg told this news organization. “Plus, when you start comparing to the COVID-negative population, especially in the first 30 days of your positive diagnosis, actually, the COVID-negative patients have essentially almost the same amount, sometimes more.”

For instance, in the first month after diagnosis, though people with COVID reported anxiety symptoms after their diagnoses, people who’d never had COVID were coming in even more often with that symptom. And although gastrointestinal disorders were common in people who’d had COVID, they were just as likely in people who had not. Nausea and vomiting were actually 19% more common in people without COVID than in those with it. And people without COVID were nearly twice as likely to develop nutritional and endocrine disorders.

In the longer run, people who’d had COVID were 25% more likely to develop dysrhythmias, 20% more likely to develop diabetes, 60% more likely to develop fatigue, 21% more likely to develop genitourinary conditions, 39% more likely to develop chest pains, and a full 3.88 times more likely to develop trouble with olfaction.

And although people who’d had COVID were numerically 5% more likely to develop both abdominal pain and vertigo, 4% more likely to develop nervous system disorders, and 1% more likely to develop anxiety disorders longer term, none of those reached statistical significance.

The only diagnosis that doesn’t make sense to Dr. Horberg is diabetes.

“At this point I don’t think it’s been fully explained,” Dr. Horberg said. “I don’t think COVID is affecting the pancreas. But I do think that these are people who probably sought medical care, who hadn’t been seeking medical care and that the findings of diabetes were incidental diagnoses.”

Still, Dr. Horberg isn’t saying never on that. “As they say, more research is needed,” he added.
 

Ready to define long COVID?

As an intensive care unit physician and pulmonologist, Michael Risbano, MD, assistant professor of medicine at the University of Pittsburgh, has seen a lot of COVID. As the co-manager of the medical system’s post-COVID clinic, he’s also seen a lot of people coming in for help with what could be long COVID. When he saw the data from Dr. Horberg’s presentation, at first it seemed to confirm what he’d already known. But then he looked further.

“Well, this is actually making sense,” Dr. Risbano thought. At his clinic, it’s been an ongoing challenge to tease out what symptoms existed before COVID. Unlike Kaiser, the University of Pittsburgh Medical Center is not a closed system.

“We know some people who tend to get sick [with COVID] have some underlying medical issues already,” Dr. Risbano said in an interview. “But we don’t always have a good baseline as to what they were like beforehand, so we don’t always know what’s changed.”

He said the study design here, though retrospective and based on chart review rather than prospective observation, starts to put symptoms into the larger context of a patient’s life. And the diabetes association really stood out to him. He recalled one patient who, when she was admitted to the ICU, had a hemoglobin A1c that was totally normal. But when that patient returned a few months later, her blood sugar had skyrocketed.

“It was sky-high, like 13, and she was in diabetic ketoacidosis,” he said. “I know that’s an N of 1, but my wife is a dietitian and a case manager, and she’s having a lot of people coming in with a new diagnosis of diabetes.”

Still, he said he’s not sure that the conditions the study identified should be the basis for a definition of long COVID.

“I don’t know if you can come up with a definition out of this,” he said. “But I think this is at least helpful in telling us what disease states are different pre- and post-COVID, and what sorts of diagnoses clinicians should look for when a patient comes in after having a COVID diagnosis.”

Dr. Horberg and Dr. Risbano have disclosed no relevant financial relationships. The study was funded by the National Institute of Allergy and Infectious Diseases at the National Institutes of Health.

About 73% of Americans are now immune to the Omicron variant, which could increase to 80% by mid-March, a university health institute says.

About half of eligible Americans have received booster shots, and about 80 million confirmed COVID-19 infections have been reported. Many more infections have occurred but haven’t been officially recorded, The Associated Press reported.

The high percentage of immunity from vaccination and previous infection tends to prevent or shorten new illnesses and reduce the amount of virus circulating overall. Health experts are now discussing whether the number is high enough to stop new waves or reduce the burden on hospitals.

“I am optimistic even if we have a surge in summer, cases will go up, but hospitalizations and deaths will not,” Ali Mokdad, PhD, a professor of health metrics sciences at the University of Washington in Seattle, told the AP.

Dr. Mokdad works on COVID-19 forecasting for the university’s Institute for Health Metrics and Evaluation, which has been a reliable model during the pandemic. Dr. Mokdad calculated the 73% number for the AP.

“We have changed,” he said. “We have been exposed to this virus and we know how to deal with it.”

The United States is now reporting about 125,000 new cases per day, according to the data tracker from the New York Times, marking a 68% decrease from the past 2 weeks. Hospitalizations are also down 39%, and about 2,300 new deaths are being reported daily, marking a 13% decline.

There will be more outbreaks as new variants emerge, immunity wanes, and some people remain unvaccinated, Dr. Mokdad said. But the coronavirus is no longer new, and the entire population is no longer “immunologically naive.” Scientists are now trying to understand how long booster protection will last against Omicron and how many people have been infected who had mild or no symptoms that were never reported.

By the end of the Omicron surge, about three out of four people in the United States will have been infected, Shaun Truelove, PhD, an epidemiologist and disease modeler at Johns Hopkins University, told the AP.

“We know it’s a huge proportion of the population,” he said. “This varies a lot by location, and in some areas, we expect the number infected to be closer to one in two.”

That means different regions and groups of people have different levels of protection and risk. In Virginia, for instance, disease modelers estimate that about 45% of residents have the highest level of immunity by being vaccinated and boosted or vaccinated with a recent Omicron infection. Another 47% have immunity that has waned somewhat.

“That’s going to be a nice shield of armor for our population as a whole,” Bryan Lewis, PhD, an epidemiologist who leads the University of Virginia’s COVID-19 modeling team, told the outlet. “If we do get to very low case rates, we certainly can ease back on some of these restrictions.”

About 7% of Virginians are considered the most vulnerable because they were never vaccinated or infected, he noted. Nationwide, about 80 million Americans are still vulnerable, the AP reported.

“The 26% who could still get Omicron right now have to be very careful,” Dr. Mokdad said.

The percentages will continue to change as immunity wanes and new variants circulate in the country. For now, the Institute for Health Metrics and Evaluation model estimates that about 63% to 81% of Americans are protected.

“We’ve reached a much better position for the coming months, but with waning immunity, we shouldn’t take it for granted,” Dr. Mokdad said.

“The 26% who could still get Omicron right now have to be very careful,” Dr. Mokdad said.

The percentages will continue to change as immunity wanes and new variants circulate in the country. For now, the Institute for Health Metrics and Evaluation model estimates that about 63% to 81% of Americans are protected.

“We’ve reached a much better position for the coming months, but with waning immunity, we shouldn’t take it for granted,” Dr. Mokdad said.

Four cases of acquired hemophilia A (AHA) identified after SARS-CoV-2 immunizations in a province in northern Italy caught the attention of researchers, who stressed that the cases are “unusual,” but not necessarily caused by vaccination.

“The overall number of cases observed does not allow ... any definitive conclusion over a possible causal relationship between SARS-CoV-2 vaccination and AHA, which would need more epidemiological and pharmacovigilance data about suspected vaccine-related adverse events,” Maria Cristina Leone, MD, of Azienda USL-IRCCS di Reggio Emilia (Italy), and colleagues reported online on Jan. 19, 2022, in a letter to the editors of Thrombosis Research.

The cases, observed in Reggio Emilia during the first 8 months of the vaccination campaign, occurred following receipt of mRNA BNT162b2 (Pfizer-BioNTech) vaccine. The AHA patients included two men and two women who ranged in age from 67 to 86 years.

During this time frame, 235,597 people received at least one dose of BNT162b2 vaccine, the authors noted.

In the 5 years prior, from January 2016 to December 2020, only zero to two cases of AHA were observed each year, totaling five cases, or 1.9 cases per million people/year. These numbers are in line with the estimated incidence of the disease, the researchers noted, adding that “it should nonetheless be underlined that vaccination benefits exceed potential side effects and play a central role in individual and public health to effectively protect people from COVID-19 and stop the pandemic.”

However, they also wrote that the “unusual observation of four cases of a rare disease during the first months of the vaccination campaign in our province could be of interest and could sensitize health care personnel toward a possible complication of SARS-CoV-2 immunization.”

AHA is a rare autoimmune disease caused by neutralizing autoantibodies against coagulation factor VIII. It is mainly associated with malignancy, autoimmune diseases, certain medications, and postnatal status.

“Sporadic AHA cases have been reported in association with infectious diseases or vaccinations,” the author noted, adding that associations between the BNT162b2 vaccine immune complications, including AHA, have also been reported by other authors.

Three of the four case patients in Reggio Emilia had “at least one common clinical association of AHA,” they found, suggesting that these associations could “reflect susceptibility to autoimmunity potentially triggered by vaccination.”

“Case four died due to complications from sepsis after being treated with steroid and rituximab, whereas the first three cases underwent clinical and laboratory remission after immunosuppressive therapy, and no relapse has been observed during follow-up, as in the other two cases reported: This could suggest a more favorable prognosis in respect to other non–vaccine-associated cases, but longer-term data are definitely needed,” they concluded.

The authors reported having no disclosures.

The recommended vaccination schedule for people in the United States aged 19 years and older has been released by the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC).

The Clinical Guideline on the “Recommended Adult Immunization Schedule, United States, 2022” appears online Feb. 17 in Annals of Internal Medicine and in the CDC’s Morbidity and Mortality Weekly Report.

The document features changes to the zoster, pneumococcal, and hepatitis B vaccines. COVID-19 vaccinations are now included in the notes section of the schedule and can be co-administered with other vaccines, according to ACIP.

The 2022 schedule is particularly important because the pandemic has caused many adults to fall behind in routine vaccinations, according to lead author Neil Murthy, MD, MPH, MSJ, of the CDC’s immunization services division, National Center for Immunization and Respiratory Diseases, and colleagues.  

“Providers should administer all due and overdue vaccines according to the routine immunization schedule during the same visit,” the group wrote. “In addition, providers should implement strategies to catch up all patients on any overdue vaccines.”

Among other changes appearing in the 2022 recommendations:

• A new step 4 in the form of an appendix lists all the contraindications and precautions for each vaccine.
• The zoster vaccine now is recommended for use in everyone aged 19 years and older who are or will be immunodeficient or immunosuppressed through disease or therapy. The new purple color bar reflects ACIP’s new two-dose series regimen for immunocompromised adults aged 19 to 49.
• The simplified pneumococcal recommendation includes guidance on using the new PCV15 and PCV20 vaccines.
• The hepatitis B recommendation has been made more inclusive, with vaccination recommended for all adults aged 19 to 59. The Special Situations section in the Notes outlines the risk-based recommendations for the hepatitis B vaccine in adults aged 60 and older. The schedule has been harmonized with the 2022 Child and Adolescent Immunization Schedule.

A welcome change

Sandra A. Fryhofer, MD, a member of the ACIP Combined Immunization Work Group, said the new pneumococcal recommendation is a particularly welcome change.

“The old recommendation was complicated and confusing. The new one is much more straightforward,” Dr. Fryhofer, an internist in Atlanta, said in an interview. Now there are only two options: a two-vaccine series of PCV15 (Vaxneuvance), in combination with the already familiar PPSV23 polysaccharide vaccine (Pneumovax 23), and a single dose of the new PCV20, Prevnar 20.

“Some work group members favored a universal age-based recommendation starting at 50 instead of 65,” Fryhofer said. “This would provide more opportunities to vaccinate adults but could lead to waning immunity later in life when risk of disease is higher.”

Although none of the updates is likely to stir controversy, discussion among ACIP members was particularly lively around hepatitis B vaccination, Dr. Fryhofer said. This vaccine has historically been recommended based on risk and has had poor uptake, while age-based vaccine recommendations generally have greater uptake.

“ACIP approved hepatitis B vaccine universally for those up to age 60, but for those 60 and older, the recommendation remains risk-based with a loophole: Anyone 60 and older who wants it can get it,” she told this news organization. “Some of the risk indications for hepatitis B vaccination may be uncomfortable or embarrassing to disclose, especially for older patients. The loophole takes care of that, but patients may have to ask for the vaccine.”

As usual, the graphics have been fine-tuned for greater accuracy and readability. “You can print a color copy to have in the exam room or at your workspace or give it a bookmark and check it online,” Dr. Fryhofer said. “It’s a great resource to have at your fingertips.”

Dr. Fryhofer has made a series of videos explaining ACIP’s approval process, the use of the schedule, and changes to vaccines including influenza. These can be accessed on the American College of Physicians website.

The authors of the recommendations stress that physicians should pay careful attention to the notes section for each vaccine, as these details clarify who needs what vaccine, when, and at what dose.

Co-author Henry Bernstein, DO, reported that he is the editor of Current Opinion in Pediatrics Office Pediatrics Series and received a presentation honorarium from the Florida chapter of the American Academy of Pediatrics. Co-author Kevin Ault, MD, reported having received a grant from the National Cancer Institute, consulting fees from PathoVax, and payments supporting attending meetings and/or travel from the American College of Obstetricians and Gynecologists.
