Trend reversed: New cases of COVID-19 decline in children
New cases of COVID-19 dropped among children for just the second time in the past 6 weeks, but that was not enough to reverse the trend in children’s share of the weekly total, according to a report from the American Academy of Pediatrics and the Children’s Hospital Association.
of all COVID-19 cases reported for the week, surpassing the pandemic-high 20.6% seen just a week earlier, the AAP/CHA report shows.
The total number of cases in children is now over 3.7 million – that’s 13.7% of cases in all ages – since the start of the pandemic, and the cumulative rate of infection has reached 4,931 per 100,000 children, based on data from 49 states (excluding New York), the District of Columbia, New York City, Puerto Rico, and Guam.
Cases of more severe illness in children continue to trend lower. The cumulative number of hospitalizations in children (15,187) is only 2.0% of the total of almost 760,000 in the 25 jurisdictions (24 states and New York City) that report such data, and deaths in children now number 296, which is just 0.06% of all COVID-19–related mortality in 43 states, New York City, Puerto Rico, and Guam, the AAP and CHA said in their report.
Among those 46 jurisdictions, Texas has reported the most deaths (51) in children, followed by Arizona (29) and New York City (23), while 9 states and the District of Columbia have reported no deaths so far. Children represent the highest proportion of deaths (0.19%) in Colorado, but Guam, with 2 child deaths among its total of 136, has by far the highest rate at 1.47%, the AAP/CHA data show.
Data from the 25 reporting jurisdictions show that children make up the largest share of hospitalizations (3.1%) in Colorado and Minnesota, while New York City (1.9%), Georgia (1.3%), and Rhode Island (1.3%) have the highest hospitalization rates among children diagnosed with SARS-CoV-2 infection, the two groups reported.

Thyroid hormone analogues can reverse NASH
Background: Fat toxicity results in inflammation of the liver and eventual hepatic fibrosis and cirrhosis. Thyroid hormones can greatly reduce this hepatic steatosis by restoring metabolic pathways in damaged liver, prevent fibrosis progression, and have broad atherogenic lipid-lowering actions by activating hepatic thyroid beta-receptors.
However, hyperthyroidism also leads to osteoporosis, tachyarrhythmias, muscle wasting, and psychiatric side effects, mediated by the alpha-thyroid receptor. Resmetirom (MGL-3196) is a novel, highly selective thyroid beta-agonist, with a minimal side-effect profile, which avoids the alpha–side effects.
Study design: Randomized, double-blind, placebo-controlled study.
Setting: 25 centers in the United States.
Synopsis: Of 125 adults with NASH fibrosis 1-3 and greater than 10% hepatic fat, 84 received resmetirom and 41 received placebo. Resmetirom resulted in a nearly 30% decrease over placebo in hepatic fat, compared with baseline, significant improvement in lipid profile, improvement in liver enzymes, fibrosis markers, and histologic resolution of NASH in some patients.
While the study showed resolution of inflammation, the 36-week study was likely not long enough to show improvement of fibrosis. The relatively small sample size also limited results. Placebo patients who lost significant weight also showed improvement and were discarded from analysis, suggesting that weight loss itself is also an excellent alternative to reverse NASH. Resmetirom use in NASH is now moving into a large phase 3 trial.
Bottom line: Resmetirom results in major liver and cardiovascular benefits in patients with NASH.

Efficacy and safety of daily low-dose colchicine after recent MI
Background: Clinical evidence supports the role of inflammation in atherosclerosis and its complications. Colchicine (Colcrys) in an orally administered potent anti-inflammatory that is currently used to treat gout and pericarditis.
Study design: Randomized, double-blind, placebo-controlled, investigator-initiated trial.
Setting: Funded by Canadian Institute of Health and Research, 167 centers in 12 different countries. Centers were predominately located in Canada, South America, and Europe.
Synopsis: In this study, 4,745 patients with a MI within the last 30 days and treated according to national guidelines were enrolled. There were multiple exclusion criteria including severe heart, renal, and/or hepatic failure. The mean age of patients was 60.6 years. Patients were followed for a median of 22.6 months. The primary endpoint was a composite of death from cardiovascular causes, resuscitated cardiac arrest, MI, stroke, or urgent hospitalization for angina leading to coronary revascularization.
The primary endpoint occurred in 5.5% of patients in the colchicine group and 7.1% of those in the placebo group (hazard ratio, 0.77). This was largely because of a decreased incidence of stroke in the colchicine group compared to placebo (0.2% vs 0.8%) and decreased urgent hospitalizations for unstable angina leading to revascularization (1.1% vs 2.1%).
Nausea was more common in the colchicine group as well as pneumonia which was reported as a serious adverse event (0.9% compared to 0.4% in placebo).
Limitations included short follow-up and significant exclusion criteria.
Bottom line: In patients following a recent myocardial infraction, the use of low-dose colchicine at 0.5 mg daily led to a significantly lower percentage of ischemic cardiovascular events compared to placebo.

Feds lift pause of J&J COVID vaccine, add new warning
Use of the Johnson & Johnson COVID-19 vaccine should resume in the United States for all adults, the Food and Drug Administration and Centers for Disease Contol and Prevention said April 23, although health care providers should warn patients of the risk of developing the rare and serious blood clots that caused the agencies to pause the vaccine’s distribution earlier this month.
“What we are seeing is the overall rate of events was 1.9 cases per million people. In women 18 to 29 years there was an approximate 7 cases per million. The risk is even lower in women over the age of 50 at .9 cases per million,” CDC Director Rochelle Walensky, MD, said in a news briefing the same day.
In the end, the potential benefits of the vaccine far outweighed its risks.
“In terms of benefits, we found that for every 1 million doses of this vaccine, the J&J vaccine could prevent over 650 hospitalizations and 12 deaths among women ages 18-49,” Dr. Walensky said. The potential benefits to women over 50 were even greater: It could prevent 4,700 hospitalizations and 650 deaths.
“In the end, this vaccine was shown to be safe and effective for the vast majority of people,” Dr. Walensky said.
The recommendation to continue the vaccine’s rollout came barely 2 hours after a CDC Advisory Committee on Immunization Practices voted to recommend the pause be lifted. The vote was 10-4 with one abstention.
The decision also includes instructions for the warning directed at women under 50 who have an increased risk of a rare but serious blood clot disorder called thrombosis with thrombocytopenia syndrome (TTS).
As of April 21, 15 cases of TTS, all in women and 13 of them in women under 50, have been confirmed among 7.98 million doses of the J&J vaccine administered in the United States. Three women have died.
The FDA and CDC recommended the pause on April 13 after reports that 6 women developed a blood clotting disorder 6 to 13 days after they received the J&J vaccine.
William Schaffner, MD, an infectious disease expert at Vanderbilt University in Nashville, and a non-voting ACIP member, said in an interview the panel made the right recommendation.
He applauded both the decision to restart the vaccine and the updated warning information that “will explain [TTS] more fully to people, particularly women, who are coming to be vaccinated.”
As to women in the risk group needing to have a choice of vaccines, Dr. Schaffner said that will be addressed differently across the country.
“Every provider will not have alternative vaccines in their location so there will be many different ways to do this. You may have to get this information and select which site you’re going to depending on which vaccine is available if this matter is important to you,” he noted.
ACIP made the decision after a 6-hour emergency meeting to hear evidence on the Johnson & Johnson vaccine's protective benefits against COVID-19 vs. risk of TTS.
In the CDC-FDA press briefing, Dr. Walensky pointed out that over the past few days, as regulators have reviewed the rare events, newly identified patients had been treated appropriately, without the use of heparin, which is not advised for treating TTS.
As a result, regulators felt as if their messages had gotten out to doctors who now knew how to take special precautions when treating patients with the disorder.
She said the Johnson & Johnson shot remained an important option because it was convenient to give and easier to store than the other vaccines currently authorized in the United States.
Peter Marks, MD, the director of FDA’s Center for Biologics Evaluation and Research, said the agency had already added information describing the risk of the rare clotting disorder to its fact sheets for patients and doctors.
Janet Woodcock, MD, acting commissioner of the FDA, said vaccination centers could resume giving the “one and done” shots as early as April 24.

Study: COVID-19 can kill months after infection
Long-haul COVID-19 patients face many health threats – including a higher chance of dying – up to 6 months after they catch the virus, according to a massive study published in the journal Nature.
Researchers examined more than 87,000 COVID-19 patients and nearly 5 million control patients in a federal database. They found COVID-19 patients had a 59% higher risk of death up to 6 months after infection, compared with noninfected people.
Those findings translate into about 8 extra deaths per 1,000 patients over 6 months, because many deaths caused by long-term COVID complications are not recorded as COVID-19 deaths, the researchers said. Among patients who were hospitalized and died after more than 30 days, there were 29 excess deaths per 1,000 patients over 6 months.
“As far as total pandemic death toll, these numbers suggest that the deaths we’re counting due to the immediate viral infection are only the tip of the iceberg,” Ziyad Al-Aly, MD, the senior author of the study and a director of the Clinical Epidemiology Center at the Veterans Affairs St. Louis Health Care System, said in a news release from the Washington University, St. Louis.
Johns Hopkins University in Baltimore says more than 3 million people worldwide and about 570,000 people in the United States have died of coronavirus-related reasons.
Long-haul COVID patients also had a much higher chance of getting sick, and not just in the respiratory system, according to the study.
The patients had a high rate of stroke and other nervous system ailments, mental health problems such as depression, the onset of diabetes, heart disease and other coronary problems, diarrhea and digestive disorders, kidney disease, blood clots, joint pain, hair loss, and general fatigue.
Patients often had clusters of these ailments. And the more severe the case of COVID-19, the higher the chance of long-term health problems, the study said.
Researchers based their study on health care databases of the U.S. Department of Veterans Affairs. Besides the 87,000 COVID patients, the database included about 5 million patients who didn’t catch COVID. The veterans in the study were about 88% men, but the large sample size included 8,880 women with confirmed cases, the news release said.
Dr. Al-Aly, an assistant professor at Washington University, said the study shows that long-haul COVID-19 could be “America’s next big health crisis.”
“Our study demonstrates that, up to 6 months after diagnosis, the risk of death following even a mild case of COVID-19 is not trivial and increases with disease severity,” he said. “Given that more than 30 million Americans have been infected with this virus, and given that the burden of long COVID-19 is substantial, the lingering effects of this disease will reverberate for many years and even decades.”

The patients had a high rate of stroke and other nervous system ailments, mental health problems such as depression, the onset of diabetes, heart disease and other coronary problems, diarrhea and digestive disorders, kidney disease, blood clots, joint pain, hair loss, and general fatigue.
Patients often had clusters of these ailments. And the more severe the case of COVID-19, the higher the chance of long-term health problems, the study said.
Researchers based their study on health care databases of the U.S. Department of Veterans Affairs. Besides the 87,000 COVID patients, the database included about 5 million patients who didn’t catch COVID. The veterans in the study were about 88% men, but the large sample size included 8,880 women with confirmed cases, the news release said.
Dr. Al-Aly, an assistant professor at Washington University, said the study shows that long-haul COVID-19 could be “America’s next big health crisis.”
“Our study demonstrates that, up to 6 months after diagnosis, the risk of death following even a mild case of COVID-19 is not trivial and increases with disease severity,” he said. “Given that more than 30 million Americans have been infected with this virus, and given that the burden of long COVID-19 is substantial, the lingering effects of this disease will reverberate for many years and even decades.”

Long-haul COVID-19 patients face many health threats – including a higher chance of dying – up to 6 months after they catch the virus, according to a massive study published in the journal Nature.
Researchers examined more than 87,000 COVID-19 patients and nearly 5 million control patients in a federal database. They found COVID-19 patients had a 59% higher risk of death up to 6 months after infection, compared with noninfected people.
Those findings translate into about 8 extra deaths per 1,000 patients over 6 months, because many deaths caused by long-term COVID complications are not recorded as COVID-19 deaths, the researchers said. Among patients who were hospitalized and died after more than 30 days, there were 29 excess deaths per 1,000 patients over 6 months.
“As far as total pandemic death toll, these numbers suggest that the deaths we’re counting due to the immediate viral infection are only the tip of the iceberg,” Ziyad Al-Aly, MD, the senior author of the study and a director of the Clinical Epidemiology Center at the Veterans Affairs St. Louis Health Care System, said in a news release from the Washington University, St. Louis.

Can we get to ‘COVID zero’? Experts predict the next 8 months
COVID-19 is likely to follow a seasonal pattern – similar to some other respiratory viruses – with fewer cases come summer 2021 followed by a jump next winter, experts predicted in a Thursday briefing.
If that pattern holds, it could mean a need to reinforce the mask-wearing message as the weather gets colder and people once again congregate indoors.
“Right now, we are projecting the United States all the way to Aug. 1 [will have] 619,000 deaths from COVID-19, with 4.7 million globally,” said Ali H. Mokdad, PhD, professor of health metrics sciences at the Institute for Health Metrics and Evaluation at the University of Washington, Seattle, during today’s media briefing sponsored by the Infectious Diseases Society of America and IHME.
The encouraging news is the vaccines appear to be working, and more Americans are getting them. “If you look at the data for these vaccines, they are extremely safe, they are extremely efficacious, and they make you basically impervious – for the most part – to getting serious disease, hospitalization, or death,” said Amesh Adalja, MD, senior scholar at Johns Hopkins University Center for Health Security in Baltimore.
“These vaccines do what they were meant to do: defang this virus,” said Dr. Adalja, who is an IDSA Fellow and adjunct assistant professor at Johns Hopkins Bloomberg School of Public Health. Emerging data out of Israel and other countries suggest a vaccinated person is less likely to transmit the virus as well, he added.
Still aiming for herd immunity
Furthermore, the U.S. Food and Drug Administration is likely to approve emergency use authorization (EUA) among teenagers 12-15 years old “imminently,” thereby expanding the pool of people potentially protected by vaccines.
Such authorization could help with overall public health efforts. “That’s simply a mathematical formula,” Dr. Adalja said. “The more people that are vaccinated, including children, the quicker we’ll get to herd immunity.”
In addition, with lower case numbers expected this summer, herd immunity might become more achievable, said Dr. Mokdad, who is also chief strategy officer for population health at the University of Washington.
As important as herd immunity is, so-called decoupling is “more important to me,” Dr. Adalja said. Decoupling refers to separating infections from the more severe outcomes, so people who get COVID-19 are less likely to need hospitalization or die from it.
Vaccines get the credit here, he added, including with the variants. “Even if you get a breakthrough infection with a variant, it’s not likely to land you in the hospital or cause serious disease or death,” Dr. Adalja said.
Masks and the uncommon cold
Wearing a mask until we reach herd immunity is important because it’s not possible to tell who is vaccinated and who isn’t, Dr. Mokdad said. “Remember, as many people are waiting to get a vaccine, all of us have access to a mask,” he said.
Dr. Adalja agreed, adding that public health guidance on masks will likely stay in place until we cross that herd immunity threshold and community circulation of the virus goes down.
“People are probably going to want to continue wearing masks, at least some proportion, because they see the benefit for other respiratory viruses,” Dr. Adalja said. “How many of you had a common cold this year?”
Variants: Some good news?
Experts are monitoring the spread of variants of concern in the United States and abroad. On a positive note, the B.1.1.7 variant first identified in the United Kingdom appears to be dominant in the United States at this time, which is potentially good for two reasons. One is that the available COVID-19 vaccines show sufficient efficacy against the strain, Dr. Mokdad said.
Second, a predominance of B.1.1.7 makes it more difficult for other emerging variants of concern like P1 [Brazil] or B.1.351 [South Africa] to gain control, Dr. Adalja said.
“B.1.1.7 is such an efficient transmitter,” he said. “That’s kind of an advantage … because the more B.1.1.7, you have the less opportunity B.1.351 and P1 have to set up shop.”
Hesitancy from misinformation
Vaccine hesitancy remains a concern, particularly at a time when some predict a drop in the number of Americans seeking vaccination. Although needle phobia plays a role in dissuading some from vaccination, the bigger issue is vaccine misinformation, Dr. Adalja said.
“Some people are just terrified when they see the needle. That’s a small part of the proportion of people who don’t want to get vaccinated,” Dr. Adalja said. In contrast, he attributed most hesitancy to misinformation about the vaccine, including reports that the vaccines are fake.
Even celebrities are getting drawn into the misinformation.
“I just had to answer something about Mariah Carey’s vaccination,” he said. Someone believed “that it was done with a retractable needle that didn’t really go into her arm.”
Vaccine hesitancy is more about people not understanding the risk-benefit analysis, taking side effects out of out of context if there are side effects, or being influenced by “arbitrary statements about microchips, infertility, or whatever it might be,” Dr. Adalja said.
The future is subject to change
“We’re expecting another rise in cases and more mortality in our winter season here in the United States,” Dr. Mokdad said, adding that the efficacy of the vaccines is likely to attenuate the mortality rate in particular.
However, as the epidemiology of the pandemic evolves, so too will the long-term predictions. Factors that could influence future numbers include the expansion of vaccination to teens 12-15 years old and (eventually) younger children, a need for booster vaccines, emerging variants, and the changing proportion of the population who are fully vaccinated or were previously infected.
Again, getting people to adhere to mask wearing come winter could be challenging if the scenario over the summer is “close to normal with less than 200 deaths a day in the United States,” he added. Asking people to wear masks again will be like “swimming upstream.”
“I think it’s a mistake to think that we’re going to get to ‘COVID zero,’ ” Dr. Adalja said. “This is not an eradicable disease. There’s only been one human infectious disease eradicated from the planet, and that’s smallpox, and it had very different characteristics.”

Lower target LDL-C cuts risk of CV events in ischemic stroke patients
Background: The beneficial role of high-intensity statins in secondary prevention of recurrent atherosclerotic stroke is well established. It is uncertain whether the observed benefit was from a reduction in the cholesterol level or to other pleotropic effects of atorvastatin. The ideal target cholesterol level for secondary prevention is unclear. This trial was conducted to help determine an ideal target LDL-C level in the prevention of CV events following ischemic stroke.
Study design: Randomized, parallel-group, event-driven trial.
Setting: Conducted in France and South Korea.
Synopsis: In this study, patients with an ischemic stroke within the last 3 months or TIAs within 15 days were randomly assigned to receive statins with or without ezetimibe (Zetia) to achieve a higher-target LDL-C level (90-110 mg/dL) vs. lower-target LDL-C (less than 70 mg/dL). The composite primary endpoint was a major cardiovascular event, which included ischemic stroke, MI, new symptoms leading to urgent coronary or carotid revascularization, or death from CV causes.
There were 2,860 patients enrolled, 1,430 were assigned to each target group. At the end of 3.5 years, the primary endpoint occurred in 8.5% of patients in the lower target group, compared with 10.9% in the higher target group (hazard ratio, 0.78; 95% confidence interval, 0.61-0.98; P = .04). Unfortunately, the trial was stopped early because of a lack of funding.
Bottom line: Using medications including statins to lower the LDL-C to less than 70 mg/dL leads to better cardiovascular outcomes following ischemic stroke.

COVID-19 infection conveys imperfect immunity in young adults
Do your patients think that getting COVID-19 is fully protective against subsequent reinfection? Tell it to the Marines.
A study of U.S. Marine recruits on their way to boot camp at Parris Island, S.C., showed that those who were seropositive at baseline, indicating prior exposure to SARS-CoV-2, remained at some risk for reinfection. They had about one-fifth the risk of subsequent infection, compared with seronegative recruits during basic training, but reinfections did occur.
The study, by Stuart C. Sealfon, MD, of Icahn School of Medicine at Mount Sinai in New York, and colleagues, was published in The Lancet Respiratory Medicine.
“Although antibodies induced by initial infection are largely protective, they do not guarantee effective SARS-CoV-2 neutralization activity or immunity against subsequent infection,” they wrote.
An infectious disease specialist who was not involved in the study said that the findings provide further evidence about the level of immunity acquired after an infection.
“It’s quite clear that reinfections do occur, they are of public health importance, and they’re something we need to be mindful of in terms of advising patients about whether a prior infection protects them from reinfection,” Mark Siedner, MD, MPH, a clinician and researcher in the division of infectious diseases at Massachusetts General Hospital, Boston, said in an interview.
The study results reinforce that “not all antibodies are the same,” said Sachin Gupta, MD, an attending physician in pulmonary and critical care medicine at Alameda Health System in Oakland, Calif. “We’re seeing still that 10% of folks who have antibodies can get infected again,” he said in an interview.
CHARM initiative
Dr. Sealfon and colleagues presented an analysis of data from the ironically named CHARM (COVID-19 Health Action Response for Marines) prospective study.
CHARM included U.S. Marine recruits, most of them male, aged 18-20 years, who were instructed to follow a 2-week unsupervised quarantine at home, after which they reported to a Marine-supervised facility for an additional 2-week quarantine.
At baseline, participants were tested for SARS-CoV-2 immunoglobulin G (IgG) seropositivity, defined as a dilution of 1:150 or more on receptor-binding domain and full-length spike protein enzyme-linked immunosorbent assay (ELISA).
The recruits filled out questionnaires asking them to report any of 14 specific COVID-19–related symptoms or any other unspecified symptom, as well as demographic information, risk factors, and a brief medical history.
Investigators tested recruits for SARS-CoV-2 infection by polymerase chain reaction (PCR) assay at weeks 0, 1, and 2 of quarantine, and any who had positive PCR results during quarantine were excluded.
Participants who had three negative swab PCR results during quarantine and a baseline serology test at the beginning of the supervised quarantine period – either seronegative or seropositive – then went on to enjoy their basic training at the Marine Corps Recruit Depot, Parris Island, S.C.
The participants were followed prospectively with PCR tests at weeks 2, 4, and 6 in both the seropositive and seronegative groups, and sera were obtained at the same time.
Holes in immunologic armor
Full data were available for a total of 189 participants who were seropositive and 2,247 who were seronegative at enrollment.
In all, 19 of 189 seropositive recruits (10%) had at least one PCR test positive for SARS-CoV-2 infection during the 6-week follow-up period. This translated into an incidence of 1.1 cases per person-year.
Of the 2,247 participants seronegative at baseline, 1,079 tested positive (6.2 cases per person-year; incidence rate ratio 0.18).
It appeared that antibodies provided some protection for seropositive recruits, as evidenced by a higher likelihood of infection among those with lower baseline full-length spike protein IgG titers than in those with higher baseline titers (hazard ratio 0.4, P < .001).
Among the seropositive participants who did acquire a second SARS-CoV-2 infection, viral loads in mid-turbinate nasal swabs were about 10-fold lower than in seronegative recruits who acquired infections during follow-up.
“This finding suggests that some reinfected individuals could have a similar capacity to transmit infection as those who are infected for the first time. The rate at which reinfection occurs after vaccines and natural immunity is important for estimating the proportion of the population that needs to be vaccinated to suppress the pandemic,” the investigators wrote.
Baseline neutralizing antibody titers were detected in 45 of the first 54 seropositive recruits who remained PCR negative throughout follow-up, but also in 6 of 19 seropositive participants who became infected during the 6 weeks of observation.
Lessons
Both Dr. Siedner and Dr. Gupta agreed with the authors that the risks for reinfection that were observed in young, physically fit people may differ for other populations, such as women (only 10% of seropositive recruits and 8% of seronegative recruits were female), older patients, or those who are immunocompromised.
Given that the adjusted odds ratio for reinfection in this study was nearly identical to that of a recent British study comparing infection rates between seropositive and seronegative health care workers, the risk of reinfection for other young adults and for the general population may be similar, Dr. Sealfon and colleagues wrote.
Adding to the challenge of reaching herd immunity is the observation that some patients who have recovered from COVID-19 are skeptical about the need for further protection.
“There are patients who feel like vaccination is of low benefit to them, and I think these are the same people who would be hesitant to get the vaccine anyway,” Dr. Gupta said.
Although no vaccine is perfect – the vaccine failure rate from the mRNA-based vaccines from Moderna and Pfizer/Biontech is about 5% – the protections they afford are unmistakable, Dr. Siedner said.
“I think it’s important to make the distinction that most postvaccination infections by and large have been very mild,” he said. “In people with normal immune systems, we have not seen an onslaught of postvaccination infections requiring hospitalization. Even if people do get infected after vaccination, the vaccines protect people from severe infection, and that’s what we want them to do.”
The investigators stated, “Young adults, of whom a high proportion are asymptomatically infected and become seropositive in the absence of known infection, can be an important source of transmission to more vulnerable populations. Evaluating the protection against subsequent SARS-CoV-2 infection conferred by seropositivity in young adults is important for determining the need for vaccinating previously infected individuals in this age group.”
The study was funded by the Defense Health Agency and Defense Advanced Research Projects Agency. Dr. Sealfon, Dr. Siedner, and Dr. Gupta have no conflicts of interest to report. Dr. Gupta is a member of the editorial advisory board for this publication.
Do your patients think that getting COVID-19 is fully protective against subsequent reinfection? Tell it to the Marines.
A study of U.S. Marine recruits on their way to boot camp at Parris Island, S.C., showed that those who were seropositive at baseline, indicating prior exposure to SARS-CoV-2, remained at some risk for reinfection. They had about one-fifth the risk of subsequent infection, compared with seronegative recruits during basic training, but reinfections did occur.
The study, by Stuart C. Sealfon, MD, of Icahn School of Medicine at Mount Sinai in New York, and colleagues, was published in The Lancet Respiratory Medicine.
“Although antibodies induced by initial infection are largely protective, they do not guarantee effective SARS-CoV-2 neutralization activity or immunity against subsequent infection,” they wrote.
An infectious disease specialist who was not involved in the study said that the findings provide further evidence about the level of immunity acquired after an infection.
“It’s quite clear that reinfections do occur, they are of public health importance, and they’re something we need to be mindful of in terms of advising patients about whether a prior infection protects them from reinfection,” Mark Siedner, MD, MPH, a clinician and researcher in the division of infectious diseases at Massachusetts General Hospital, Boston, said in an interview.
The study results reinforce that “not all antibodies are the same,” said Sachin Gupta, MD, an attending physician in pulmonary and critical care medicine at Alameda Health System in Oakland, Calif. “We’re seeing still that 10% of folks who have antibodies can get infected again,” he said in an interview.
CHARM initiative
Dr. Sealfon and colleagues presented an analysis of data from the ironically named CHARM (COVID-19 Health Action Response for Marines) prospective study.
CHARM included U.S. Marine recruits, most of them male, aged 18-20 years, who were instructed to follow a 2-week unsupervised quarantine at home, after which they reported to a Marine-supervised facility for an additional 2-week quarantine.
At baseline, participants were tested for SARS-CoV-2 immunoglobulin G (IgG) seropositivity, defined as a dilution of 1:150 or more on receptor-binding domain and full-length spike protein enzyme-linked immunosorbent assay (ELISA).
The recruits filled out questionnaires asking them to report any of 14 specific COVID-19–related symptoms or any other unspecified symptom, as well as demographic information, risk factors, and a brief medical history.
Investigators tested recruits for SARS-CoV-2 infection by polymerase chain reaction (PCR) assay at weeks 0, 1, and 2 of quarantine, and any who had positive PCR results during quarantine were excluded.
Participants who had three negative swab PCR results during quarantine and a baseline serology test at the beginning of the supervised quarantine period – either seronegative or seropositive – then went on to enjoy their basic training at the Marine Corps Recruit Depot, Parris Island, S.C.
The participants were followed prospectively with PCR tests at weeks 2, 4, and 6 in both the seropositive and seronegative groups, and sera were obtained at the same time.
Holes in immunologic armor
Full data were available for a total of 189 participants who were seropositive and 2,247 who were seronegative at enrollment.
In all, 19 of 189 seropositive recruits (10%) had at least one PCR test positive for SARS-CoV-2 infection during the 6-week follow-up period. This translated into an incidence of 1.1 cases per person-year.
Of the 2,247 participants seronegative at baseline, 1,079 tested positive (6.2 cases per person-year; incidence rate ratio 0.18).
It appeared that antibodies provided some protection for seropositive recruits, as evidenced by a higher likelihood of infection among those with lower baseline full-length spike protein IgG titers than in those with higher baseline titers (hazard ratio 0.4, P < .001).
Among the seropositive participants who did acquire a second SARS-CoV-2 infection, viral loads in mid-turbinate nasal swabs were about 10-fold lower than in seronegative recruits who acquired infections during follow-up.
“This finding suggests that some reinfected individuals could have a similar capacity to transmit infection as those who are infected for the first time. The rate at which reinfection occurs after vaccines and natural immunity is important for estimating the proportion of the population that needs to be vaccinated to suppress the pandemic,” the investigators wrote.
Baseline neutralizing antibody titers were detected in 45 of the first 54 seropositive recruits who remained PCR negative throughout follow-up, but also in 6 of 19 seropositive participants who became infected during the 6 weeks of observation.
Lessons
Both Dr. Siedner and Dr. Gupta agreed with the authors that the risks for reinfection that were observed in young, physically fit people may differ for other populations, such as women (only 10% of seropositive recruits and 8% of seronegative recruits were female), older patients, or those who are immunocompromised.
Given that the adjusted odds ratio for reinfection in this study was nearly identical to that of a recent British study comparing infection rates between seropositive and seronegative health care workers, the risk of reinfection for other young adults and for the general population may be similar, Dr. Sealfon and colleagues wrote.
Adding to the challenge of reaching herd immunity is the observation that some patients who have recovered from COVID-19 are skeptical about the need for further protection.
“There are patients who feel like vaccination is of low benefit to them, and I think these are the same people who would be hesitant to get the vaccine anyway,” Dr. Gupta said.
Although no vaccine is perfect – the vaccine failure rate from the mRNA-based vaccines from Moderna and Pfizer/Biontech is about 5% – the protections they afford are unmistakable, Dr. Siedner said.

COVID plus MI confers poor prognosis; 1 in 3 die in hospital
COVID-19 patients with ST-segment elevation MI (STEMI) represent a population with unique demographic and clinical features resulting in a high risk for mortality, according to initial findings from the North American Cardiovascular COVID-19 Myocardial Infarction (NACMI) Registry.
“This is the largest registry of COVID-positive patients presenting with STEMI [and] the results clearly illustrate the challenges and uniqueness of this patient population that deserves prompt and special attention,” study cochair Timothy Henry, MD, president-elect of the Society for Cardiovascular Angiography & Interventions, said in a news release.
The NACMI registry is a collaborative effort between the SCAI, the American College of Cardiology Interventional Council, and the Canadian Association of Interventional Cardiology.
“The rapid development of this ongoing, critically important prospective registry reflects the strong and unique collaboration of all three societies. It was gratifying to be part of this process and hopefully the results will improve the care of our patients and stimulate further research,” Dr. Henry said in the news release.
The registry has enrolled 1,185 patients presenting with STEMI at 64 sites across the United States and Canada. Participants include 230 COVID-positive STEMI patients; 495 STEMI patients suspected but ultimately confirmed not to have COVID-19; and 460 age-and sex-matched control STEMI patients treated prior to the pandemic who are part of the Midwest STEMI Consortium.
The initial findings from the registry were published online in the Journal of the American College of Cardiology.
Atypical symptoms may explain high death rate
The primary outcome – a composite of in-hospital death, stroke, recurrent MI, or repeat unplanned revascularization – occurred in 36% of COVID-positive patients, compared with 13% of COVID-negative patients and 5% of control patients (P < .001 relative to controls).
This difference was driven largely by a “very high” in-hospital death rate in COVID-positive patients, lead author Santiago Garcia, MD, Minneapolis Heart Institute Foundation, said in an interview.
The in-hospital death rate was 33% in COVID-positive patients, compared with 11% in COVID-negative patients and 4% in controls. Stroke also occurred more often in COVID-positive patients at 3% versus 2% in COVID-negative and 0% in controls.
These initial findings suggest that the combination of STEMI and COVID-19 infection “confers a poor prognosis, with one in three patients succumbing to the disease, even among patients selected for invasive angiography (28% mortality),” the investigators wrote.
The data also show that STEMI in COVID-positive patients disproportionately affects ethnic minorities (23% Hispanic and 24% Black) with diabetes, which was present in 46% of COVID-positive patients.
COVID-positive patients with STEMI are more likely to present with atypical symptoms such as dyspnea (54%), pulmonary infiltrates on chest x-ray (46%), and high-risk conditions such as cardiogenic shock (18%), “which may explain the high fatality rate,” Dr. Garcia said.
Despite these high-risk features, COVID-positive patients are less apt to undergo invasive angiography when compared with COVID-negative and control STEMI patients (78% vs. 96% vs. 100%).
The majority of patients (71%) who did under angiography received primary percutaneous coronary intervention (PPCI) with very small treatment delays (at 15 minutes) during the pandemic.
Another notable finding is that “many patients (23%) have ‘no culprit’ vessel and may represent different etiologies of ST-segment elevation including microemboli, myocarditis, Takotsubo cardiomyopathy,” Dr. Garcia said in an interview.
“In line with current guidelines, patients with suspected STEMI should be managed with PPCI, without delay while the safety of health care providers is ensured,” Ran Kornowski, MD, and Katia Orvin, MD, both with Rabin Medical Center, Petah Tikva, Israel, and Tel Aviv University, wrote in a linked editorial.
“In this case, PPCI should be performed routinely, even if the patient is presumed to have COVID-19, because PPCI should not be postponed. Confirmation of SARS-CoV-2 infection should not delay urgent decision management concerning reperfusion strategy,” they advised.
Looking ahead, Garcia said plans for the registry include determining predictors of in-hospital mortality and studying demographic and treatment trends as the pandemic continues with more virulent strains of the virus.
Various subgroup analyses are also planned as well as an independent angiographic and electrocardiographic core lab analysis. A comparative analysis of data from the US and Canada is also planned.
This work was supported by an ACC Accreditation Grant, Saskatchewan Health Research Foundation, and grants from Medtronic and Abbott Vascular to SCAI. Dr. Garcia has received institutional research grants from Edwards Lifesciences, BSCI, Medtronic, and Abbott Vascular; has served as a consultant for Medtronic and BSCI; and has served as a proctor for Edwards Lifesciences.

Assessing the efficacy and safety of dapagliflozin in patients with HFrEF
Background: Guideline-directed medical therapy (use of beta-blockers, ACE inhibitor/angiotensin receptor blockers, and mineralocorticoid antagonists) provides clear benefits on mortality and morbidity in patients with HFrEF. Dapagliflozin (Farxiga) belongs to a class of sodium-glucose transporter 2 (SGLT2) inhibitors that inhibits reabsorption of sodium and glucose in the kidney and treats type 2 diabetes. This new class of drugs is emerging as an effective tool in the management of HFrEF based on the recent publication of the primary results of the DAPA-HF trial (Study to Evaluate the Effect of Dapagliflozin on the Incidence of Worsening Heart Failure or Cardiovascular Death in Patients with Chronic Heart Failure). It demonstrated substantial benefits in terms of heart failure symptoms, hospitalizations, and mortality when added to triple therapy for patients with chronic HFrEF regardless of the presence of diabetes.
Study design: Randomized, controlled double-blind trials.
Setting: 410 participating institutions in 20 countries.
Synopsis: Men and women aged 18 years and older with HFrEF who had New York Heart Association (NYHA) functional class II or higher, and optimally treated with pharmacologic and device therapy for HF were randomized to receive dapagliflozin or placebo. A total of 4,744 patients, aged 22-94 years were enrolled in the study.
- Dapagliflozin showed a clinically significant benefit on health status (symptoms, physical function, and quality of life). Improved health-related quality of life (as measured by the well-validated Kansas City Cardiomyopathy Questionnaire score) with dapagliflozin in comparison with placebo was sustained for more than 8 months.
- Dapagliflozin reduced the risk of death and worsening heart failure and improved symptoms across the broad spectrum of ages studied in DAPA-HF. There was no significant imbalance in tolerability or safety events between dapagliflozin and placebo, even in elderly individuals.
Bottom line: Follow-up DAPA-HF studies further support the role of SGLT2 inhibitor dapagliflozin in improving mortality, reducing hospitalization, and improving the quality of life in patients with HFrEF and is considered a safe option across all age groups.

Background: Guideline-directed medical therapy (use of beta-blockers, ACE inhibitor/angiotensin receptor blockers, and mineralocorticoid antagonists) provides clear benefits on mortality and morbidity in patients with HFrEF. Dapagliflozin (Farxiga) belongs to a class of sodium-glucose transporter 2 (SGLT2) inhibitors that inhibits reabsorption of sodium and glucose in the kidney and treats type 2 diabetes. This new class of drugs is emerging as an effective tool in the management of HFrEF based on the recent publication of the primary results of the DAPA-HF trial (Study to Evaluate the Effect of Dapagliflozin on the Incidence of Worsening Heart Failure or Cardiovascular Death in Patients with Chronic Heart Failure). It demonstrated substantial benefits in terms of heart failure symptoms, hospitalizations, and mortality when added to triple therapy for patients with chronic HFrEF regardless of the presence of diabetes.
Study design: Randomized, controlled double-blind trials.
Setting: 410 participating institutions in 20 countries.
Synopsis: Men and women aged 18 years and older with HFrEF who had New York Heart Association (NYHA) functional class II or higher, and optimally treated with pharmacologic and device therapy for HF were randomized to receive dapagliflozin or placebo. A total of 4,744 patients, aged 22-94 years were enrolled in the study.
- Dapagliflozin showed a clinically significant benefit on health status (symptoms, physical function, and quality of life). Improved health-related quality of life (as measured by the well-validated Kansas City Cardiomyopathy Questionnaire score) with dapagliflozin in comparison with placebo was sustained for more than 8 months.
- Dapagliflozin reduced the risk of death and worsening heart failure and improved symptoms across the broad spectrum of ages studied in DAPA-HF. There was no significant imbalance in tolerability or safety events between dapagliflozin and placebo, even in elderly individuals.
Bottom line: Follow-up DAPA-HF studies further support the role of SGLT2 inhibitor dapagliflozin in improving mortality, reducing hospitalization, and improving the quality of life in patients with HFrEF and is considered a safe option across all age groups.
