Covid ICYMI

TOPLINE:

The COVID-19 booster vaccine typically causes transient, clinically insignificant elevations in glucose levels in people with type 1 diabetes, but some individuals may develop more pronounced hyperglycemia.

METHODOLOGY:

• In a single-center prospective cohort study of 21 adults with type 1 diabetes, patients were given a blinded Dexcom G6 Pro continuous glucose monitor (CGM) at the first research clinic visit.
• After 3-4 days, participants received a COVID-19 booster vaccine.
• They returned to the clinic 10 days after the initial visit (5-6 days after booster vaccination) to have the CGM removed and glycemia assessed.

TAKEAWAY:

• Compared with baseline, the mean daily glucose level was significantly increased at day 2 (162.9 mg/dL vs. 172.8 mg/dL; P = .04) and day 3 (173.1 mg/dL; P = .02) post vaccination.
• Glucose excursions at day 0 (173.2 mg/dL; P = .058) and day 1 (173.1 mg/dL; P = .078) didn’t quite reach statistical significance.
• One participant experienced increases in glucose of 36%, 69%, 35%, 26%, 22%, and 19% on days 0-5, respectively, compared with baseline.
• Glucose excursions of at least 25% above baseline occurred in four participants on day 0 and day 1 and in three participants on days 2 and 5.
• Insulin resistance, as measured by Total Daily Insulin Resistance (a metric that integrates daily mean glucose concentration with total daily insulin dose), was also significantly increased from baseline to day 2 post vaccination (7,171 mg/dL vs. 8,070 mg/dL units; P = .03).
• No other measures of glycemia differed significantly, compared with baseline.
• Outcomes didn’t differ significantly by sex, age, or vaccine manufacturer.

IN PRACTICE:

• “To our knowledge this is the first study investigating the effect of the COVID-19 booster vaccine on glycemia specifically in people with type 1 diabetes,” say the authors.
• “Clinicians, pharmacists, and other health care providers may need to counsel people with T1D to be more vigilant with glucose testing and insulin dosing for the first 5 days after vaccination. Most importantly, insulin, required to control glycemia, may need to be transiently increased.”
• “Further studies are warranted to investigate whether other vaccines have similar glycemic effects, and which individuals are at highest risk for profound glucose perturbations post vaccination.”

SOURCE:

The study was conducted by Mihail Zilbermint, MD, of the division of hospital medicine, Johns Hopkins Medicine, Bethesda, Md., and colleagues. It was published in Diabetes Research and Clinical Practice.

LIMITATIONS:

• The sample size was small.
• There were no measurements of inflammatory markers, dietary intake, physical activity, or survey patient symptomatology to adjust for variables that may have influenced glycemic control.
• In the study cohort, glycemia was moderately well controlled at baseline.

DISCLOSURES:

The study was supported by an investigator-initiated study grant from DexCom Inc. Dr. Zilbermint has consulted for EMD Serono.

A new meta-analysis has shown that SGLT2 inhibitors do not lead to lower 28-day all-cause mortality, compared with usual care or placebo, in patients hospitalized with COVID-19.

However, no major safety issues were identified with the use of SGLT2 inhibitors in these acutely ill patients, the researchers report.

“While these findings do not support the use of SGLT2-inhibitors as standard of care for patients hospitalized with COVID-19, I think the most important take home message here is that the use of these medications appears to be safe even in really acutely ill hospitalized patients,” lead investigator of the meta-analysis, Mikhail Kosiborod, MD, Saint Luke’s Mid America Heart Institute, Kansas City, Mo., concluded.

He said this was important because the list of indications for SGLT2 inhibitors is rapidly growing.

“These medications are being used in more and more patients. And we know that when we discontinue medications in the hospital they frequently don’t get restarted, which can lead to real risks if SGLT2 inhibitors are stopped in patients with heart failure, chronic kidney disease, or diabetes. So, the bottom line is that there is no compelling reason to stop these medications in the hospital,” he added.

The new meta-analysis was presented at the recent annual congress of the European Society of Cardiology, held in Amsterdam.

Discussant of the presentation at the ESC Hotline session, Muthiah Vaduganathan, MD, MPH, Brigham and Women’s Hospital, Boston, agreed with Dr. Kosiborod’s interpretation.

“Until today we have had very limited information on the safety of SGLT2-inhibitors in acute illness, as the pivotal trials which established the use of these drugs in diabetes and chronic kidney disease largely excluded patients who were hospitalized,” Dr. Vaduganathan said.

“While the overall results of this meta-analysis are neutral and SGLT2 inhibitors will not be added as drugs to be used in the primary care of patients with COVID-19, it certainly sends a strong message of safety in acutely ill patients,” he added.

Dr. Vaduganathan explained that from the beginning of the COVID-19 pandemic, there was great interest in repurposing established therapies for alternative indications for their use in the management of COVID-19.

“Conditions that strongly predispose to adverse COVID outcomes strongly overlap with established indications for SGLT2-inhibitors. So many wondered whether these drugs may be an ideal treatment candidate for the management of COVID-19. However, there have been many safety concerns about the use of SGLT2-inhibitors in this acute setting, with worries that they may induce hemodynamic changes such an excessive lowering of blood pressure, or metabolic changes such as ketoacidosis in acutely ill patients,” he noted.

The initial DARE-19 study investigating SGLT2-inhibitors in COVID-19, with 1,250 participants, found a 20% reduction in the primary outcome of organ dysfunction or death, but this did not reach statistical significance, and no safety issues were seen. This “intriguing” result led to two further larger trials – the ACTIV-4a and RECOVERY trials, Dr. Vaduganathan reported.

“Those early signals of benefit seen in DARE-19 were largely not substantiated in the ACTIV-4A and RECOVERY trials, or in this new meta-analysis, and now we have this much larger body of evidence and more stable estimates about the efficacy of these drugs in acutely ill COVID-19 patients,” he said.

“But the story that we will all take forward is one of safety. This set of trials was arguably conducted in some of the sickest patients we’ve seen who have been exposed to SGLT2-inhibitors, and they strongly affirm that these agents can be safely continued in the setting of acute illness, with very low rates of ketoacidosis and kidney injury, and there was no prolongation of hospital stay,” he commented.

In his presentation, Dr. Kosiborod explained that treatments targeting COVID-19 pathobiology such as dysregulated immune responses, endothelial damage, microvascular thrombosis, and inflammation have been shown to improve the key outcomes in this patient group.

SGLT2 inhibitors, which modulate similar pathobiology, provide cardiovascular protection and prevent the progression of kidney disease in patients at risk for these events, including those with type 2 diabetes, heart failure, and kidney disease, and may also lead to organ protection in a setting of acute illness such as COVID-19, he noted. However, the role of SGLT2 inhibitors in patients hospitalized with COVID-19 remains uncertain.

To address the need for more definitive efficacy data, the World Health Organization Rapid Evidence Appraisal for COVID-19 Therapies (REACT) Working Group conducted a prospective meta-analysis using data from the three randomized controlled trials, DARE-19, RECOVERY, and ACTIV-4a, evaluating SGLT2 inhibitors in patients hospitalized with COVID-19.

Overall, these trials randomized 6,096 participants: 3,025 to SGLT2 inhibitors and 3,071 to usual care or placebo. The average age of participants ranged between 62 and 73 years across the trials, 39% were women, and 25% had type 2 diabetes.

By 28 days after randomization, all-cause mortality, the primary endpoint, had occurred in 11.6% of the SGLT2-inhibitor patients, compared with 12.4% of those randomized to usual care or placebo, giving an odds ratio of 0.93 (95% confidence interval, 0.79-1.08; P = .33) for SGLT2 inhibitors, with consistency across trials.

Data on in-hospital and 90-day all-cause mortality were only available for two out of three trials (DARE-19 and ACTIV-4a), but the results were similar to the primary endpoint showing nonsignificant trends toward a possible benefit in the SGLT2-inhibitor group.

The results were also similar for the secondary outcomes of progression to acute kidney injury or requirement for dialysis or death, and progression to invasive mechanical ventilation, extracorporeal membrane oxygenation, or death, both assessed at 28 days.

The primary safety outcome of ketoacidosis by 28 days was observed in seven and two patients allocated to SGLT2 inhibitors and usual care or placebo, respectively, and overall, the incidence of reported serious adverse events was balanced between treatment groups.

The RECOVERY trial was supported by grants to the University of Oxford from UK Research and Innovation, the National Institute for Health and Care Research, and Wellcome. The ACTIV-4a platform was sponsored by the National Heart, Lung, and Blood Institute. DARE-19 was an investigator-initiated collaborative trial supported by AstraZeneca. Dr. Kosiborod reported numerous conflicts of interest.

COVID vaccines will have a new formulation in 2023, according to a decision announced by the U.S. Food and Drug Administration, that will focus efforts on circulating variants. The move pushes last year’s bivalent vaccines out of circulation because they will no longer be authorized for use in the United States.

The updated mRNA vaccines for 2023-2024 are being revised to include a single component that corresponds to the Omicron variant XBB.1.5. Like the bivalents offered before, the new monovalents are being manufactured by Moderna and Pfizer.

The new vaccines are authorized for use in individuals age 6 months and older.  And the new options are being developed using a similar process as previous formulations, according to the FDA.
 

Targeting circulating variants

In recent studies, regulators point out the extent of neutralization observed by the updated vaccines against currently circulating viral variants causing COVID-19, including EG.5, BA.2.86, appears to be of a similar magnitude to the extent of neutralization observed with previous versions of the vaccines against corresponding prior variants.

“This suggests that the vaccines are a good match for protecting against the currently circulating COVID-19 variants,” according to the report.

Hundreds of millions of people in the United States have already received previously approved mRNA COVID vaccines, according to regulators who say the benefit-to-risk profile is well understood as they move forward with new formulations.

“Vaccination remains critical to public health and continued protection against serious consequences of COVID-19, including hospitalization and death,” Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, said in a statement. “The public can be assured that these updated vaccines have met the agency’s rigorous scientific standards for safety, effectiveness, and manufacturing quality. We very much encourage those who are eligible to consider getting vaccinated.”
 

Timing the effort

On Sept. 12 the U.S. Centers for Disease Control and Prevention recommended that everyone 6 months and older get an updated COVID-19 vaccine. Updated vaccines from Pfizer-BioNTech and Moderna will be available later this week, according to the agency.

Hundreds of millions of people in the United States have already received previously approved mRNA COVID vaccines, according to regulators who say the benefit-to-risk profile is well understood as they move forward with new formulations.

“Vaccination remains critical to public health and continued protection against serious consequences of COVID-19, including hospitalization and death,” Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, said in a statement. “The public can be assured that these updated vaccines have met the agency’s rigorous scientific standards for safety, effectiveness, and manufacturing quality. We very much encourage those who are eligible to consider getting vaccinated.”
 

Timing the effort

On Sept. 12 the U.S. Centers for Disease Control and Prevention recommended that everyone 6 months and older get an updated COVID-19 vaccine. Updated vaccines from Pfizer-BioNTech and Moderna will be available later this week, according to the agency.

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.

The Centers for Disease Control and Prevention and the World Health Organization have dubbed the BA 2.86 variant of COVID-19 as a variant to watch. 

So far, only 26 cases of “Pirola,” as the new variant is being called, have been identified: 10 in Denmark, four each in Sweden and the United States, three in South Africa, two in Portugal, and one each the United Kingdom, Israel, and Canada. BA 2.86 is a subvariant of Omicron, but according to reports from the CDC, the strain has many more mutations than the ones that came before it. 

With so many facts still unknown about this new variant, this news organization asked experts what people need to be aware of as it continues to spread.
 

What is unique about the BA 2.86 variant? 

“It is unique in that it has more than three mutations on the spike protein,” said Purvi S. Parikh, MD, an infectious disease expert at New York University’s Langone Health. The virus uses the spike proteins to enter our cells. 

This “may mean it will be more transmissible, cause more severe disease, and/or our vaccines and treatments may not work as well, as compared to other variants,” she said.
 

What do we need to watch with BA 2.86 going forward? 

“We don’t know if this variant will be associated with a change in the disease severity. We currently see increased numbers of cases in general, even though we don’t yet see the BA.2.86 in our system,” said Heba Mostafa, PhD, director of the molecular virology laboratory at Johns Hopkins Hospital in Baltimore. 

“It is important to monitor BA.2.86 (and other variants) and understand how its evolution impacts the number of cases and disease outcomes,” she said. “We should all be aware of the current increase in cases, though, and try to get tested and be treated as soon as possible, as antivirals should be effective against the circulating variants.” 
 

What should doctors know?

Dr. Parikh said doctors should generally expect more COVID cases in their clinics and make sure to screen patients even if their symptoms are mild.

“We have tools that can be used – antivirals like Paxlovid are still efficacious with current dominant strains such as EG.5,” she said. “And encourage your patients to get their boosters, mask, wash hands, and social distance.”
 

How well can our vaccines fight BA 2.86?

“Vaccine coverage for the BA.2.86 is an area of uncertainty right now,” said Dr. Mostafa. 

In its report, the CDC said scientists are still figuring out how well the updated COVID vaccine works. It’s expected to be available in the fall, and for now, they believe the new shot will still make infections less severe, new variants and all. 

Prior vaccinations and infections have created antibodies in many people, and that will likely provide some protection, Dr. Mostafa said. “When we experienced the Omicron wave in December 2021, even though the variant was distant from what circulated before its emergence and was associated with a very large increase in the number of cases, vaccinations were still protective against severe disease.” 
 

What is the most important thing to keep track of when it comes to this variant?

According to Dr. Parikh, “it’s most important to monitor how transmissible [BA 2.86] is, how severe it is, and if our current treatments and vaccines work.” 

Dr. Mostafa said how well the new variants escape existing antibody protection should also be studied and watched closely. 
 

What does this stage of the virus mutation tell us about where we are in the pandemic?

The history of the coronavirus over the past few years shows that variants with many changes evolve and can spread very quickly, Dr. Mostafa said. “Now that the virus is endemic, it is essential to monitor, update vaccinations if necessary, diagnose, treat, and implement infection control measures when necessary.”

With the limited data we have so far, experts seem to agree that while the variant’s makeup raises some red flags, it is too soon to jump to any conclusions about how easy it is to catch it and the ways it may change how the virus impacts those who contract it.

COVID-19 hospitalizations have been on the rise for weeks as summer nears its end, but how concerned should you be? SARS-CoV-2, the virus behind COVID, continues to evolve and surprise us. So COVID transmission, hospitalization, and death rates can be difficult to predict. 

This news organization turned to the experts for their take on the current circulating virus, asking them to predict if we’ll be masking up again anytime soon, and what this fall and winter might look like, especially now that testing and vaccinations are no longer free of charge.
 

Question 1: Are you expecting an end-of-summer COVID wave to be substantial?

Eric Topol, MD: “This wave won’t likely be substantial and could be more of a ‘wavelet.’ I’m not thinking that physicians are too concerned,” said Dr. Topol, founder and director of Scripps Research Translational Institute in La Jolla, Calif. 

Thomas Gut, DO: “It’s always impossible to predict the severity of COVID waves. Although the virus has generally mutated in ways that favor easier transmission and milder illness, there have been a handful of surprising mutations that were more dangerous and deadly than the preceding strain,” said Dr. Gut, associate chair of medicine at Staten Island University Hospital/Northwell Health in New York.

Robert Atmar, MD: “I’ll start with the caveat that prognosticating for SARS-CoV-2 is a bit hazardous as we remain in unknown territory for some aspects of its epidemiology and evolution,” said Dr. Atmar, a professor of infectious diseases at Baylor College of Medicine in Houston. “It depends on your definition of substantial. We, at least in Houston, are already in the midst of a substantial surge in the burden of infection, at least as monitored through wastewater surveillance. The amount of virus in the wastewater already exceeds the peak level we saw last winter. That said, the increased infection burden has not translated into large increases in hospitalizations for COVID-19. Most persons hospitalized in our hospital are admitted with infection, not for the consequences of infection.”

Stuart Campbell Ray, MD: “It looks like there is a rise in infections, but the proportional rise in hospitalizations from severe cases is lower than in the past, suggesting that folks are protected by the immunity we’ve gained over the past few years through vaccination and prior infections. Of course, we should be thinking about how that applies to each of us – how recently we had a vaccine or COVID-19, and whether we might see more severe infections as immunity wanes,” said Dr. Ray, who is a professor of medicine in the division of infectious diseases at Johns Hopkins University in Baltimore. 

Question 2: Is a return to masks or mask mandates coming this fall or winter?

Dr. Topol: “Mandating masks doesn’t work very well, but we may see wide use again if a descendant of [variant] BA.2.86 takes off.”

Dr. Gut: “It’s difficult to predict if there are any mask mandates returning at any point. Ever since the Omicron strains emerged, COVID has been relatively mild, compared to previous strains, so there probably won’t be any plan to start masking in public unless a more deadly strain appears.”

Dr. Atmar: “I do not think we will see a return to mask mandates this fall or winter for a variety of reasons. The primary one is that I don’t think the public will accept mask mandates. However, I think masking can continue to be an adjunctive measure to enhance protection from infection, along with booster vaccination.”

Dr. Ray: “Some people will choose to wear masks during a surge, particularly in situations like commuting where they don’t interfere with what they’re doing. They will wear masks particularly if they want to avoid infection due to concerns about others they care about, disruption of work or travel plans, or concerns about long-term consequences of repeated COVID-19.”

Question 3: Now that COVID testing and vaccinations are no longer free of charge, how might that affect their use?

Dr. Topol: “It was already low, and this will undoubtedly further compromise their uptake.”

Dr. Gut: “I do expect that testing will become less common now that tests are no longer free. I’m sure there will be a lower amount of detection in patients with milder or asymptomatic disease compared to what we had previously.”

Dr. Atmar: “If there are out-of-pocket costs for the SARS-CoV-2 vaccine, or if the administrative paperwork attached to getting a vaccine is increased, the uptake of SARS-CoV-2 vaccines will likely decrease. It will be important to communicate to the populations targeted for vaccination the potential benefits of such vaccination.”

Dr. Ray: “A challenge with COVID-19, all along, has been disparities in access to care, and this will be worse without public support for prevention and testing. This applies to everyone but is especially burdensome for those who are often marginalized in our health care system and society in general. I hope that we’ll find ways to ensure that people who need tests and vaccinations are able to access them, as good health is in everyone’s interest.”

Question 4: Will the new vaccines against COVID work for the currently circulating variants?

Dr. Topol: “The XBB.1.5 boosters will be out Sept. 14. They should help versus EG.5.1 and FL.1.5.1. The FL.1.5.1 variant is gaining now.”

Dr. Gut: “In the next several weeks, we expect the newer monovalent XBB-based vaccines to be offered that offer good protection against current circulating COVID variants along with the new Eris variant.”

Dr. Atmar: “The vaccines are expected to induce immune responses to the currently circulating variants, most of which are strains that evolved from the vaccine strain. The vaccine is expected to be most effective in preventing severe illness and will likely be less effective in preventing infection and mild illness.”

Dr. Ray: “Yes, the updated vaccine design has a spike antigen (XBB.1.5) nearly identical to the current dominant variant (EG.5). Even as variants change, the boosters stimulate B cells and T cells to help protect in a way that is safer than getting COVID-19 infection.”

Question 5: Is there anything we should watch out for regarding the BA.2.86 variant in particular?

Dr. Topol: “The scenario could change if there are new functional mutations added to it.”

Dr. Gut: “BA.2.86 is still fairly uncommon and does not have much data to directly make any informed guesses. However, in general, people that have been exposed to more recent mutations of the COVID virus have been shown to have more protection from newer upcoming mutations. It’s fair to guess that people that have not had recent infection from COVID, or have not had a recent booster, are at higher risk for being infected by any XBB- or BA.2-based strains.”

Dr. Atmar: BA.2.86 has been designated as a variant under monitoring. We will want to see whether it becomes more common and if there are any unexpected characteristics associated with infection by this variant.”

Dr. Ray: “It’s still rare, but it’s been seen in geographically dispersed places, so it’s got legs. The question is how effectively it will bypass some of the immunity we’ve gained. T cells are likely to remain protective, because they target so many parts of the virus that change more slowly, but antibodies from B cells to spike protein may have more trouble recognizing BA.2.86, whether those antibodies were made to a vaccine or a prior variant.”

COVID-19 hospitalizations have been on the rise for weeks as summer nears its end, but how concerned should you be? SARS-CoV-2, the virus behind COVID, continues to evolve and surprise us. So COVID transmission, hospitalization, and death rates can be difficult to predict. 

This news organization turned to the experts for their take on the current circulating virus, asking them to predict if we’ll be masking up again anytime soon, and what this fall and winter might look like, especially now that testing and vaccinations are no longer free of charge.
 

Question 1: Are you expecting an end-of-summer COVID wave to be substantial?

Eric Topol, MD: “This wave won’t likely be substantial and could be more of a ‘wavelet.’ I’m not thinking that physicians are too concerned,” said Dr. Topol, founder and director of Scripps Research Translational Institute in La Jolla, Calif. 

Thomas Gut, DO: “It’s always impossible to predict the severity of COVID waves. Although the virus has generally mutated in ways that favor easier transmission and milder illness, there have been a handful of surprising mutations that were more dangerous and deadly than the preceding strain,” said Dr. Gut, associate chair of medicine at Staten Island University Hospital/Northwell Health in New York.

Robert Atmar, MD: “I’ll start with the caveat that prognosticating for SARS-CoV-2 is a bit hazardous as we remain in unknown territory for some aspects of its epidemiology and evolution,” said Dr. Atmar, a professor of infectious diseases at Baylor College of Medicine in Houston. “It depends on your definition of substantial. We, at least in Houston, are already in the midst of a substantial surge in the burden of infection, at least as monitored through wastewater surveillance. The amount of virus in the wastewater already exceeds the peak level we saw last winter. That said, the increased infection burden has not translated into large increases in hospitalizations for COVID-19. Most persons hospitalized in our hospital are admitted with infection, not for the consequences of infection.”

Stuart Campbell Ray, MD: “It looks like there is a rise in infections, but the proportional rise in hospitalizations from severe cases is lower than in the past, suggesting that folks are protected by the immunity we’ve gained over the past few years through vaccination and prior infections. Of course, we should be thinking about how that applies to each of us – how recently we had a vaccine or COVID-19, and whether we might see more severe infections as immunity wanes,” said Dr. Ray, who is a professor of medicine in the division of infectious diseases at Johns Hopkins University in Baltimore. 

Question 2: Is a return to masks or mask mandates coming this fall or winter?

Dr. Topol: “Mandating masks doesn’t work very well, but we may see wide use again if a descendant of [variant] BA.2.86 takes off.”

Dr. Gut: “It’s difficult to predict if there are any mask mandates returning at any point. Ever since the Omicron strains emerged, COVID has been relatively mild, compared to previous strains, so there probably won’t be any plan to start masking in public unless a more deadly strain appears.”

Dr. Atmar: “I do not think we will see a return to mask mandates this fall or winter for a variety of reasons. The primary one is that I don’t think the public will accept mask mandates. However, I think masking can continue to be an adjunctive measure to enhance protection from infection, along with booster vaccination.”

Dr. Ray: “Some people will choose to wear masks during a surge, particularly in situations like commuting where they don’t interfere with what they’re doing. They will wear masks particularly if they want to avoid infection due to concerns about others they care about, disruption of work or travel plans, or concerns about long-term consequences of repeated COVID-19.”

Question 3: Now that COVID testing and vaccinations are no longer free of charge, how might that affect their use?

Dr. Topol: “It was already low, and this will undoubtedly further compromise their uptake.”

Dr. Gut: “I do expect that testing will become less common now that tests are no longer free. I’m sure there will be a lower amount of detection in patients with milder or asymptomatic disease compared to what we had previously.”

Dr. Atmar: “If there are out-of-pocket costs for the SARS-CoV-2 vaccine, or if the administrative paperwork attached to getting a vaccine is increased, the uptake of SARS-CoV-2 vaccines will likely decrease. It will be important to communicate to the populations targeted for vaccination the potential benefits of such vaccination.”

Dr. Ray: “A challenge with COVID-19, all along, has been disparities in access to care, and this will be worse without public support for prevention and testing. This applies to everyone but is especially burdensome for those who are often marginalized in our health care system and society in general. I hope that we’ll find ways to ensure that people who need tests and vaccinations are able to access them, as good health is in everyone’s interest.”

Question 4: Will the new vaccines against COVID work for the currently circulating variants?

Dr. Topol: “The XBB.1.5 boosters will be out Sept. 14. They should help versus EG.5.1 and FL.1.5.1. The FL.1.5.1 variant is gaining now.”

Dr. Gut: “In the next several weeks, we expect the newer monovalent XBB-based vaccines to be offered that offer good protection against current circulating COVID variants along with the new Eris variant.”

Dr. Atmar: “The vaccines are expected to induce immune responses to the currently circulating variants, most of which are strains that evolved from the vaccine strain. The vaccine is expected to be most effective in preventing severe illness and will likely be less effective in preventing infection and mild illness.”

Dr. Ray: “Yes, the updated vaccine design has a spike antigen (XBB.1.5) nearly identical to the current dominant variant (EG.5). Even as variants change, the boosters stimulate B cells and T cells to help protect in a way that is safer than getting COVID-19 infection.”

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.

By the end of August 2022, overall use of mental health services was almost 40% higher than before the COVID-19 pandemic, while spending increased by 54%, according to a new study by researchers at the RAND Corporation.

During the early phase of the pandemic, from mid-March to mid-December 2020, before the vaccine was available, in-person visits decreased by 40%, while telehealth visits increased by 1,000%, reported Jonathan H. Cantor, PhD, and colleagues at RAND, and at Castlight Health, a benefit coordination provider, in a paper published online in JAMA Health Forum.

Between December 2020 and August 2022, telehealth visits stayed stable, but in-person visits creeped back up, eventually reaching 80% of prepandemic levels. However, “total utilization was higher than before the pandemic,” Dr. Cantor, a policy researcher at RAND, told this news organization. 

“It could be that it’s easier for individuals to receive care via telehealth, but it could also just be that there’s a greater demand or need since the pandemic,” said Dr. Cantor. “We’ll just need more research to actually unpack what’s going on,” he said.

Initial per capita spending increased by about a third and was up overall by more than half. But it’s not clear how much of that is due to utilization or to price of services, said Dr. Cantor. Spending for telehealth services remained stable in the post-vaccine period, while spending on in-person visits returned to prepandemic levels.

Dr. Cantor and his colleagues were not able to determine whether utilization was by new or existing patients, but he said that would be good data to have. “It would be really important to know whether or not folks are initiating care because telehealth is making it easier,” he said.

The authors analyzed about 1.5 million claims for anxiety disorders, major depressive disorder, bipolar disorder, schizophrenia, and posttraumatic stress disorder, out of claims submitted by 7 million commercially insured adults whose self-insured employers used the Castlight benefit.

Dr. Cantor noted that this is just a small subset of the U.S. population. He said he’d like to have data from Medicare and Medicaid to fully assess the impact of the COVID-19 pandemic on mental health and of telehealth visits.

“This is a still-burgeoning field,” he said about telehealth. “We’re still trying to get a handle on how things are operating, given that there’s been so much change so rapidly.”

Meanwhile, 152 major employers responding to a large national survey this summer said that they’ve been grappling with how COVID-19 has affected workers. The employers include 72 Fortune 100 companies and provide health coverage for more than 60 million workers, retirees, and their families.

Seventy-seven percent said they are currently seeing an increase in depression, anxiety, and substance use disorders as a result of the pandemic, according to the Business Group on Health’s survey. That’s up from 44% in 2022.

Going forward, employers will focus on increasing access to mental health services, the survey reported.

“Our survey found that in 2024 and for the near future, employers will be acutely focused on addressing employees’ mental health needs while ensuring access and lowering cost barriers,” Ellen Kelsay, president and CEO of Business Group on Health, said in a statement.

The study was supported by grants from the National Institute of Mental Health and the National Institute on Aging. Coauthor Dena Bravata, MD, a Castlight employee, reported receiving personal fees from Castlight Health during the conduct of the study. Coauthor Christopher M. Whaley, a RAND employee, reported receiving personal fees from Castlight Health outside the submitted work.

Cantor, PhD, and colleagues at RAND, and at Castlight Health, a benefit coordination provider, in a paper published online in JAMA Health Forum.

Between December 2020 and August 2022, telehealth visits stayed stable, but in-person visits creeped back up, eventually reaching 80% of prepandemic levels. However, “total utilization was higher than before the pandemic,” Dr. Cantor, a policy researcher at RAND, told this news organization. 

“It could be that it’s easier for individuals to receive care via telehealth, but it could also just be that there’s a greater demand or need since the pandemic,” said Dr. Cantor. “We’ll just need more research to actually unpack what’s going on,” he said.

Initial per capita spending increased by about a third and was up overall by more than half. But it’s not clear how much of that is due to utilization or to price of services, said Dr. Cantor. Spending for telehealth services remained stable in the post-vaccine period, while spending on in-person visits returned to prepandemic levels.

Dr. Cantor and his colleagues were not able to determine whether utilization was by new or existing patients, but he said that would be good data to have. “It would be really important to know whether or not folks are initiating care because telehealth is making it easier,” he said.

The authors analyzed about 1.5 million claims for anxiety disorders, major depressive disorder, bipolar disorder, schizophrenia, and posttraumatic stress disorder, out of claims submitted by 7 million commercially insured adults whose self-insured employers used the Castlight benefit.

Dr. Cantor noted that this is just a small subset of the U.S. population. He said he’d like to have data from Medicare and Medicaid to fully assess the impact of the COVID-19 pandemic on mental health and of telehealth visits.

“This is a still-burgeoning field,” he said about telehealth. “We’re still trying to get a handle on how things are operating, given that there’s been so much change so rapidly.”

Meanwhile, 152 major employers responding to a large national survey this summer said that they’ve been grappling with how COVID-19 has affected workers. The employers include 72 Fortune 100 companies and provide health coverage for more than 60 million workers, retirees, and their families.

Seventy-seven percent said they are currently seeing an increase in depression, anxiety, and substance use disorders as a result of the pandemic, according to the Business Group on Health’s survey. That’s up from 44% in 2022.

Going forward, employers will focus on increasing access to mental health services, the survey reported.

“Our survey found that in 2024 and for the near future, employers will be acutely focused on addressing employees’ mental health needs while ensuring access and lowering cost barriers,” Ellen Kelsay, president and CEO of Business Group on Health, said in a statement.

The study was supported by grants from the National Institute of Mental Health and the National Institute on Aging. Coauthor Dena Bravata, MD, a Castlight employee, reported receiving personal fees from Castlight Health during the conduct of the study. Coauthor Christopher M. Whaley, a RAND employee, reported receiving personal fees from Castlight Health outside the submitted work.

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.

A new strain of COVID-19 that was identified only a week ago in the United States has prompted the Centers for Disease Control and Prevention to take the rare step of issuing a formal message that it could evade vaccines or the protection of natural immunity. 

The strain is called BA.2.86 and is of particular concern because of its more than 30 mutations, which means it may behave very differently than previous versions of the virus. That number of mutations is on par with the difference between variants so serious that they were formally named, such as between Delta and Omicron, the CDC explained in the risk assessment issued Aug. 23.

Worldwide, health agencies are issuing a flurry of updates on BA.2.86. The strain only recently landed on the World Health Organization’s radar when it was named a “variant under monitoring” on Aug. 17. The CDC announced the same day that it had been detected in the United States.

Among the characteristics the CDC monitors for are how contagious a strain is, how well it responds to treatment, and how severely it affects people.

“BA.2.86 may be more capable of causing infection in people who have previously had COVID-19 or who have received COVID-19 vaccines,” the CDC risk assessment stated.

The agency is evaluating how well the forthcoming updated vaccine, due out in September, performs against BA.2.86.

A new forecast also released this week by the CDC predicts hospitalizations due to the virus will continue their upward trend through at least mid-September. Currently, about 1,800 people are hospitalized daily with COVID-19. The new prediction shows that number has a small potential to drop as low as 1,100 daily, but it could also increase by as many as 7,500 per day. The most likely scenario lands somewhere in the middle of that range, with daily hospital admissions of between 2,000 and 4,000 people by Sept. 18.

The CDC said there is “no evidence” that BA.2.86 is causing more severe illness but said that could change as more information becomes available. Health experts typically gauge severity by the rate of COVID hospitalizations.

The journal Nature reported that many scientists see similarities between the emergence of BA.2.86 and that of Omicron, which rapidly spread around the world in late 2021.

“There’s a little bit of déjà vu all over again,” University of Michigan virologist Adam Lauring, MD, PhD, whose lab detected one of the first U.S. cases of BA.2.86, told Nature.

Dr. Lauring, as well as the CDC and the WHO, all caution that more data is needed to truly understand the threat posed by BA.2.86.

“There’s good reason to think it won’t be like the Omicron wave, but it’s early days,” Dr. Lauring said.
