Nearly one-third of adults over age 65 developed one or more new medical conditions in the weeks following a COVID-19 infection, according to new research.

The findings of the observational study, which were published in the BMJ, show the risk of a new condition being triggered by COVID is more than twice as high in seniors, compared with younger patients. Plus, the researchers observed an even higher risk among those who were hospitalized, with nearly half (46%) of patients having developed new conditions after the acute COVID-19 infection period.

Respiratory failure with shortness of breath was the most common postacute sequela, but a wide range of heart, kidney, lung, liver, cognitive, mental health, and other conditions were diagnosed at least 3 weeks after initial infection and persisted beyond 30 days.

This is one of the first studies to specifically describe the incidence and severity of new conditions triggered by COVID-19 infection in a general sample of older adults, said study author Ken Cohen MD, FACP, executive director of translational research at Optum Labs and national senior medical director at Optum Care.

“Much of what has been published on the postacute sequelae of COVID-19 has been predominantly from a younger population, and many of the patients had been hospitalized,” Dr. Cohen noted. “This was the first study to focus on a large population of seniors, most of whom did not require hospitalization.”

Dr. Cohen and colleagues reviewed the health insurance records of more than 133,000 Medicare beneficiaries aged 65 or older who were diagnosed with COVID-19 before April 2020. They also matched individuals by age, race, sex, hospitalization status, and other factors to comparison groups without COVID-19 (one from 2020 and one from 2019), and to a group diagnosed with other lower respiratory tract viral infections before the pandemic.
 

Risk of developing new conditions was higher in hospitalized

After acute COVID-19 infection, 32% of seniors sought medical care for at least one new medical condition in 2020, compared with 21% of uninfected people in the same year.

The most commonly observed conditions included:

• Respiratory failure (7.55% higher risk).
• Fatigue (5.66% higher risk).
• High blood pressure (4.43% higher risk).
• Memory problems (2.63% higher risk).
• Kidney injury (2.59% higher risk).
• Mental health diagnoses (2.5% higher risk).
• Blood-clotting disorders (1.47 % higher risk).
• Heart rhythm disorders (2.9% higher risk).

The risk of developing new conditions was even higher among those 23,486 who were hospitalized in 2020. Those individuals showed a 23.6% higher risk for developing at least one new condition, compared with uninfected seniors in the same year. Also, patients older than 75 had a higher risk for neurological disorders, including dementia, encephalopathy, and memory problems. The researchers also found that respiratory failure and kidney injury were significantly more likely to affect men and Black patients.

When those who had COVID were compared with the group with other lower respiratory viral infections before the pandemic, only the risks of respiratory failure (2.39% higher), dementia (0.71% higher), and fatigue (0.18% higher) were higher.

Primary care providers can learn from these data to better evaluate and manage their geriatric patients with COVID-19 infection, said Amit Shah, MD, a geriatrician with the Mayo Clinic in Phoenix, in an interview.

“We must assess older patients who have had COVID-19 for more than just improvement from the respiratory symptoms of COVID-19 in post-COVID follow-up visits,” he said. “Older individuals with frailty have vulnerability to subsequent complications from severe illnesses and it is common to see post-illness diagnoses, such as new diagnosis of delirium; dementia; or renal, respiratory, or cardiac issues that is precipitated by the original illness. This study confirms that this is likely the case with COVID-19 as well.

“Primary care physicians should be vigilant for these complications, including attention to the rehabilitation needs of older patients with longer-term postviral fatigue from COVID-19,” Dr. Shah added.
 

Data predates ‘Omicron wave’

It remains uncertain whether sequelae will differ with the Omicron variant, but the findings remain applicable, Dr. Cohen said.

“We know that illness from the Omicron variant is on average less severe in those that have been vaccinated. However, throughout the Omicron wave, individuals who have not been vaccinated continue to have significant rates of serious illness and hospitalization,” he said.

“Our findings showed that serious illness with hospitalization was associated with a higher rate of sequelae. It can therefore be inferred that the rates of sequelae seen in our study would continue to occur in unvaccinated individuals who contract Omicron, but might occur less frequently in vaccinated individuals who contract Omicron and have less severe illness.”

Johnson & Johnson stopped making its COVID-19 vaccine at a key facility in the Netherlands.

The Johnson & Johnson shot is seen as a critical vaccine for poorer countries. But late last year the company paused production at the only plant making usable batches of the vaccine, people familiar with the decision told The New York Times.

The plant, located in Leiden, has been making an experimental but potentially more profitable vaccine instead. The experimental vaccine is for an unrelated virus -- respiratory syncytial virus, or RSV -- that will be used for a clinical trial.

The pause is said to be temporary. The Leiden plant is expected to restart production of the COVID-19 vaccine next month. The company has said that it has millions of COVID-19 doses in inventory, though it’s unclear whether the pause has affected vaccine supplies.

The interruption could reduce the supply of Johnson & Johnson’s COVID-19 vaccine by a few hundred million doses, one of the sources told the newspaper, since the doses made from renewed production won’t likely ship until May or June. Other facilities have been hired to produce the vaccine but aren’t running yet or haven’t received regulatory approval to ship doses for packaging.

Jake Sargent, a spokesman for Johnson & Johnson, told the Times that the company is “focused on ensuring our vaccine is available where people are in need” and that its global production network “is working day and night.” He said that the company has millions of doses in inventory and is continuing to deliver vaccine batches to facilities that package doses.

The pause has surprised officials at two main recipients of the Johnson & Johnson shots -- the African Union and Covax, the organization that coordinates COVID-19 vaccines for poorer countries. Leaders of the two organizations learned about the halt in production from reporters at the Times.

“This is not the time to be switching production lines of anything, when the lives of people across the developing world hang in the balance,” Ayoade Alakija, coleader of the African Union’s vaccine delivery program, told the newspaper.

Poorer countries rely on Johnson & Johnson’s vaccine because it doesn’t require ultracold refrigeration. The vaccine is also less expensive than others and easy to provide to hard-to-reach populations.

“In many low- and middle-income countries, our vaccine is the most important and sometimes only option,” Penny Heaton, MD, a Johnson & Johnson executive, said in December during a meeting with the CDC’s vaccine advisory committee.

“We have a global vaccine, and the world is depending on us,” she said.

Goffin’s cockatoo? More like golfin’ cockatoo

Can birds play golf? Of course not; it’s ridiculous. Humans can barely play golf, and we invented the sport. Anyway, moving on to “Brian retraction injury after elective aneurysm clipping.”

Hang on, we’re now hearing that a group of researchers, as part of a large international project comparing children’s innovation and problem-solving skills with those of cockatoos, have in fact taught a group of Goffin’s cockatoos how to play golf. Huh. What an oddly specific project. All right, fine, I guess we’ll go with the golf-playing birds.

Goffin Lab

Golf may seem very simple at its core. It is, essentially, whacking a ball with a stick. But the Scots who invented the game were undertaking a complex project involving combined usage of multiple tools, and until now, only primates were thought to be capable of utilizing compound tools to play games such as golf.

For this latest research, published in Scientific Reports, our intrepid birds were given a rudimentary form of golf to play (featuring a stick, a ball, and a closed box to get the ball through). Putting the ball through the hole gave the bird a reward. Not every cockatoo was able to hole out, but three did, with each inventing a unique way to manipulate the stick to hit the ball.

As entertaining as it would be to simply teach some birds how to play golf, we do loop back around to medical relevance. While children are perfectly capable of using tools, young children in particular are actually quite bad at using tools to solve novel solutions. Present a 5-year-old with a stick, a ball, and a hole, and that child might not figure out what the cockatoos did. The research really does give insight into the psychology behind the development of complex tools and technology by our ancient ancestors, according to the researchers.

We’re not entirely convinced this isn’t an elaborate ploy to get a bird out onto the PGA Tour. The LOTME staff can see the future headline already: “Painted bunting wins Valspar Championship in epic playoff.”
 

Work out now, sweat never

Okay, show of hands: Who’s familiar with “Name that tune?” The TV game show got a reboot last year, but some of us are old enough to remember the 1970s version hosted by national treasure Tom Kennedy.

Edith Cowan University

The contestants try to identify a song as quickly as possible, claiming that they “can name that tune in five notes.” Or four notes, or three. Well, welcome to “Name that exercise study.”

Senior author Masatoshi Nakamura, PhD, and associates gathered together 39 students from Niigata (Japan) University of Health and Welfare and had them perform one isometric, concentric, or eccentric bicep curl with a dumbbell for 3 seconds a day at maximum effort for 5 days a week, over 4 weeks. And yes, we did say 3 seconds.

“Lifting the weight sees the bicep in concentric contraction, lowering the weight sees it in eccentric contraction, while holding the weight parallel to the ground is isometric,” they explained in a statement on Eurekalert.

The three exercise groups were compared with a group that did no exercise, and after 4 weeks of rigorous but brief science, the group doing eccentric contractions had the best results, as their overall muscle strength increased by 11.5%. After a total of just 60 seconds of exercise in 4 weeks. That’s 60 seconds. In 4 weeks.

Big news, but maybe we can do better. “Tom, we can do that exercise in 2 seconds.”

And one! And two! Whoa, feel the burn.
 

Tingling over anxiety

Apparently there are two kinds of people in this world. Those who love ASMR and those who just don’t get it.

ASMR, for those who don’t know, is the autonomous sensory meridian response. An online community has surfaced, with video creators making tapping sounds, whispering, or brushing mannequin hair to elicit “a pleasant tingling sensation originating from the scalp and neck which can spread to the rest of the body” from viewers, Charlotte M. Eid and associates said in PLOS One.

The people who are into these types of videos are more likely to have higher levels of neuroticism than those who aren’t, which gives ASMR the potential to be a nontraditional form of treatment for anxiety and/or neuroticism, they suggested.

The research involved a group of 64 volunteers who watched an ASMR video meant to trigger the tingles and then completed questionnaires to evaluate their levels of neuroticism, trait anxiety, and state anxiety, said Ms. Eid and associates of Northumbria University in Newcastle-upon-Tyne, England.

The people who had a history of producing tingles from ASMR videos in the past had higher levels of anxiety, compared with those who didn’t. Those who responded to triggers also received some benefit from the video in the study, reporting lower levels of neuroticism and anxiety after watching, the investigators found.

Although people who didn’t have a history of tingles didn’t feel any reduction in anxiety after the video, that didn’t stop the people who weren’t familiar with the genre from catching tingles.

So if you find yourself a little high strung or anxious, or if you can’t sleep, consider watching a person pretending to give you a makeover or using fingernails to tap on books for some relaxation. Don’t knock it until you try it!
 

Living in the past? Not so far-fetched

It’s usually an insult when people tell us to stop living in the past, but the joke’s on them because we really do live in the past. By 15 seconds, to be exact, according to researchers from the University of California, Berkeley.

Mauro Manassi

But wait, did you just read that last sentence 15 seconds ago, even though it feels like real time? Did we just type these words now, or 15 seconds ago?

Think of your brain as a web page you’re constantly refreshing. We are constantly seeing new pictures, images, and colors, and your brain is responsible for keeping everything in chronological order. This new research suggests that our brains show us images from 15 seconds prior. Is your mind blown yet?

“One could say our brain is procrastinating. It’s too much work to constantly update images, so it sticks to the past because the past is a good predictor of the present. We recycle information from the past because it’s faster, more efficient and less work,” senior author David Whitney explained in a statement from the university.

It seems like the 15-second rule helps us not lose our minds by keeping a steady flow of information, but it could be a bit dangerous if someone, such as a surgeon, needs to see things with extreme precision.

And now we are definitely feeling a bit anxious about our upcoming heart/spleen/gallbladder replacement. … Where’s that link to the ASMR video?

And now we are definitely feeling a bit anxious about our upcoming heart/spleen/gallbladder replacement. … Where’s that link to the ASMR video?

Goffin’s cockatoo? More like golfin’ cockatoo

Can birds play golf? Of course not; it’s ridiculous. Humans can barely play golf, and we invented the sport. Anyway, moving on to “Brian retraction injury after elective aneurysm clipping.”

Hang on, we’re now hearing that a group of researchers, as part of a large international project comparing children’s innovation and problem-solving skills with those of cockatoos, have in fact taught a group of Goffin’s cockatoos how to play golf. Huh. What an oddly specific project. All right, fine, I guess we’ll go with the golf-playing birds.

Goffin Lab

Golf may seem very simple at its core. It is, essentially, whacking a ball with a stick. But the Scots who invented the game were undertaking a complex project involving combined usage of multiple tools, and until now, only primates were thought to be capable of utilizing compound tools to play games such as golf.

For this latest research, published in Scientific Reports, our intrepid birds were given a rudimentary form of golf to play (featuring a stick, a ball, and a closed box to get the ball through). Putting the ball through the hole gave the bird a reward. Not every cockatoo was able to hole out, but three did, with each inventing a unique way to manipulate the stick to hit the ball.

As entertaining as it would be to simply teach some birds how to play golf, we do loop back around to medical relevance. While children are perfectly capable of using tools, young children in particular are actually quite bad at using tools to solve novel solutions. Present a 5-year-old with a stick, a ball, and a hole, and that child might not figure out what the cockatoos did. The research really does give insight into the psychology behind the development of complex tools and technology by our ancient ancestors, according to the researchers.

We’re not entirely convinced this isn’t an elaborate ploy to get a bird out onto the PGA Tour. The LOTME staff can see the future headline already: “Painted bunting wins Valspar Championship in epic playoff.”
 

Work out now, sweat never

Okay, show of hands: Who’s familiar with “Name that tune?” The TV game show got a reboot last year, but some of us are old enough to remember the 1970s version hosted by national treasure Tom Kennedy.

Edith Cowan University

The contestants try to identify a song as quickly as possible, claiming that they “can name that tune in five notes.” Or four notes, or three. Well, welcome to “Name that exercise study.”

Senior author Masatoshi Nakamura, PhD, and associates gathered together 39 students from Niigata (Japan) University of Health and Welfare and had them perform one isometric, concentric, or eccentric bicep curl with a dumbbell for 3 seconds a day at maximum effort for 5 days a week, over 4 weeks. And yes, we did say 3 seconds.

“Lifting the weight sees the bicep in concentric contraction, lowering the weight sees it in eccentric contraction, while holding the weight parallel to the ground is isometric,” they explained in a statement on Eurekalert.

The three exercise groups were compared with a group that did no exercise, and after 4 weeks of rigorous but brief science, the group doing eccentric contractions had the best results, as their overall muscle strength increased by 11.5%. After a total of just 60 seconds of exercise in 4 weeks. That’s 60 seconds. In 4 weeks.

Big news, but maybe we can do better. “Tom, we can do that exercise in 2 seconds.”

And one! And two! Whoa, feel the burn.
 

Tingling over anxiety

Apparently there are two kinds of people in this world. Those who love ASMR and those who just don’t get it.

ASMR, for those who don’t know, is the autonomous sensory meridian response. An online community has surfaced, with video creators making tapping sounds, whispering, or brushing mannequin hair to elicit “a pleasant tingling sensation originating from the scalp and neck which can spread to the rest of the body” from viewers, Charlotte M. Eid and associates said in PLOS One.

The people who are into these types of videos are more likely to have higher levels of neuroticism than those who aren’t, which gives ASMR the potential to be a nontraditional form of treatment for anxiety and/or neuroticism, they suggested.

The research involved a group of 64 volunteers who watched an ASMR video meant to trigger the tingles and then completed questionnaires to evaluate their levels of neuroticism, trait anxiety, and state anxiety, said Ms. Eid and associates of Northumbria University in Newcastle-upon-Tyne, England.

The people who had a history of producing tingles from ASMR videos in the past had higher levels of anxiety, compared with those who didn’t. Those who responded to triggers also received some benefit from the video in the study, reporting lower levels of neuroticism and anxiety after watching, the investigators found.

Although people who didn’t have a history of tingles didn’t feel any reduction in anxiety after the video, that didn’t stop the people who weren’t familiar with the genre from catching tingles.

So if you find yourself a little high strung or anxious, or if you can’t sleep, consider watching a person pretending to give you a makeover or using fingernails to tap on books for some relaxation. Don’t knock it until you try it!
 

Living in the past? Not so far-fetched

It’s usually an insult when people tell us to stop living in the past, but the joke’s on them because we really do live in the past. By 15 seconds, to be exact, according to researchers from the University of California, Berkeley.

Mauro Manassi

But wait, did you just read that last sentence 15 seconds ago, even though it feels like real time? Did we just type these words now, or 15 seconds ago?

Think of your brain as a web page you’re constantly refreshing. We are constantly seeing new pictures, images, and colors, and your brain is responsible for keeping everything in chronological order. This new research suggests that our brains show us images from 15 seconds prior. Is your mind blown yet?

“One could say our brain is procrastinating. It’s too much work to constantly update images, so it sticks to the past because the past is a good predictor of the present. We recycle information from the past because it’s faster, more efficient and less work,” senior author David Whitney explained in a statement from the university.

It seems like the 15-second rule helps us not lose our minds by keeping a steady flow of information, but it could be a bit dangerous if someone, such as a surgeon, needs to see things with extreme precision.

And now we are definitely feeling a bit anxious about our upcoming heart/spleen/gallbladder replacement. … Where’s that link to the ASMR video?

Long COVID can affect adults, young people, and children, and now for the first time, in a landmark study accepted for publication in the Archives of Disease in Childhood, formal agreement has been made on a research definition for post–acute COVID-19, or “long COVID” as it is commonly known, in children and young people.

The researchers charged themselves with a single objective – to derive a research definition for long COVID (post–acute COVID-19) in children and young people to allow comparisons between research studies. Specifically, so studies on prevalence, course, and outcome of long COVID in this age group can be reliably compared, because to date there has been no consensus. In fact, the authors pointed out how the “slew of definitions” currently used all differ in number, type, and duration of symptoms, which hampers research efforts. In addition, the lack of definition consensus has contributed to very wide reported variations in the estimated prevalence of long COVID in children of 1%-51%, with the authors saying that a “consistently applied definition of long COVID will help reduce the variability of prevalence estimates.”
 

Statements sequentially whittled down

“Using robust consensus methodology,” the authors said, “we derived a research definition for long COVID in children and young people.”

To achieve the definition consensus, a three-phase online Delphi process was used, followed by a virtual consensus meeting. The 123 participants registered to take part in the study included 23 people (19%) in a lived experience panel, 50 (42%) in the researcher or researcher/service delivery combined panel and 47 (39%) in the service delivery panel. Of 120 registered participants, 105 (88%) completed phase 1, 86 eligible participants (82% of those completing phase 1) completed phase 2 and 77 eligible participants (90% of those completing phase 2) completed phase 3. Seventeen participants attended and voted at the consensus meeting – 4 (23%) from the service delivery panel, 11 (65%) from the researcher panel, and 2 (12%) from the lived experience panel.

Presented with 49 statements in each phase, participants scored these from 1-9 based on how important they were perceived to be with regards inclusion in the research definition of long COVID in children and young people. Having been sequentially whittled down in three phases, 10 statements were discussed at the consensus meeting, and a panel of eight 11- to 17-year-olds affected by long COVID also reviewed the statements to reach a final agreement.

Five of the statements were agreed to be included in the definition, which stated that long COVID in children and young people is a condition in which a child or young person has symptoms (at least one of which is a physical symptom) that have continued or developed after a diagnosis of COVID-19 (confirmed with one or more positive COVID tests); impact their physical, mental, or social well-being; are interfering with some aspect of daily living (for example, school, work, home, or relationships); and persist for a minimum duration of 12 weeks after initial testing for COVID-19 (even if symptoms have waxed and waned over that period).

David Strain, MBChB, MD, chair of the BMA board of science and clinical senior lecturer and honorary consultant, University of Exeter (England), told the Science Media Centre: “A Delphi study builds a consensus from the world’s experts by presenting a series of statements and continuing to refine them until there is agreement as to what the definition of pediatric long COVID should be.” He added: “This is vitally important in order to align the global research effort into long COVID.”
 

Reassuringly similar

From the agreed five statements, a further research definition was proposed to align with the World Health Organization definition for adults: “Post–COVID-19 condition occurs in young people with a history of confirmed SARS CoV-2 infection, with at least one persisting physical symptom for a minimum duration of 12 weeks after initial testing that cannot be explained by an alternative diagnosis. The symptoms have an impact on everyday functioning, may continue or develop after COVID-19 infection, and may fluctuate or relapse over time.”

The authors concluded: “This is the first research definition of long COVID (post–COVID-19 condition) in children and young people and complements the clinical case definition in adults proposed by WHO,” adding that the two definitions are “reassuringly similar.”

They reiterated how widespread adoption of this definition would allow comparisons between studies such that a core outcome set can be developed and the prevalence, course and outcome of long COVID in children and young people can be reliably evaluated, which “will substantially help strengthen the evidence base on this debilitating condition.”

In addition, the authors said that a consistently applied definition of long COVID will help to provide a “more accurate picture on the true impact of the condition.”

The researchers emphasized the need to differentiate between a clinical case definition and a research definition of long COVID and explained: “It is understandable that the patient groups representing people with long COVID are concerned about a definition that could restrict access to services that are needed.”

They went on to say that in their view the decision whether a child or young person can see a health care professional, access any support needed, or be referred, investigated, or treated for long COVID should be a “shared decision involving the young person, their carers, and clinicians.”

Dr. Strain reinforced that it was important that the definition was a research one and not a clinical one, pointing out that the 12-week period in the research definition “does not necessarily mean that a child or young person should need to wait 3 months before being offered help or assistance from their health care team, indeed a 3-month delay in offering support to a child or young person, at this vitally important period of their educational development, could have lasting long-term impacts.”

It’s a story of promise at a time of urgent need.

Scientists are optimistic about new evidence into what is causing long COVID, a panel of research experts brought together by the New York State Department of Health said.

They proposed many theories on what might be driving long COVID. A role for a virus “cryptic reservoir” that could reactivate at any time, “viral remnants” that trigger chronic inflammation, and action by “autoimmune antibodies” that cause ongoing symptoms are possibilities.

In fact, it’s likely that research will show long COVID is a condition with more than one cause, the experts said during a recent webinar.

People might experience post-infection problems, including organ damage that takes time to heal after initial COVID-19 illness. Or they may be living with post-immune factors, including ongoing immune system responses triggered by autoantibodies.

Determining the cause or causes of long COVID is essential for treatment. For example, if one person’s symptoms persist because of an overactive immune system, “we need to provide immunosuppressant therapies,” Akiko Iwasaki, PhD, said. “But we don’t want to give that to someone who has a persistent virus reservoir,” meaning remnants of the virus remain in their bodies.

Interestingly, a study preprint, which has not been peer reviewed, found dogs were accurate more than half the time in sniffing out long COVID, said Dr. Iwasaki, professor of immunobiology and developmental biology at Yale University, New Haven, Conn.

The dogs were tasked with identifying 45 people with long COVID versus 188 people without it. The findings suggest the presence of a unique chemical in the sweat of people with long COVID that could someday lead to a diagnostic test.
 

Viral persistence possible

If one of the main theories holds, it could be that the coronavirus somehow remains in the body in some form for some people after COVID-19.

Mady Hornig, MD, agreed this is a possibility that needs to be investigated further.

“A weakened immune response to an infection may mean that you have cryptic reservoirs of virus that are continuing to cause symptoms,” she said during the briefing. Dr. Hornig is a doctor-scientist specializing in epidemiology at Columbia University, New York.

“That may explain why some patients with long COVID feel better after vaccination,” because the vaccine creates a strong antibody response to fight COVID-19, Dr. Iwasaki said.

Researchers are unearthing additional potential factors contributing to long COVID.

Viral persistence could also reactivate other dormant viruses in the body, such as Epstein-Barr virus (EBV), said Lawrence Purpura, MD, MPH, an infectious disease specialist at New York Presbyterian/Columbia University. Reactivation of Epstein-Barr is one of four identifying signs of long COVID revealed in a Jan. 25 study published in the journal Cell.
 

Immune overactivation also possible?

For other people with long COVID, it’s not the virus sticking around but the body’s reaction that’s the issue.

Investigators suggest autoimmunity plays a role, and they point to the presence of autoantibodies, for example.

When these autoantibodies persist, they can cause tissue and organ damage over time.

Other investigators are proposing “immune exhaustion” in long COVID because of similarities to chronic fatigue syndrome, Dr. Hornig said.

“It should be ‘all hands on deck’ for research into long COVID,” she said. “The number of disabled individuals who will likely qualify for a diagnosis of [chronic fatigue syndrome] is growing by the second.”
 

Forging ahead on future research

It’s clear there is more work to do. There are investigators working on banking tissue samples from people with long COVID to learn more, for example.

Also, finding a biomarker unique to long COVID could vastly improve the precision of diagnosing long COVID, especially if the dog sniffing option does not pan out.

Of the thousands of biomarker possibilities, Dr. Hornig said, “maybe that’s one or two that ultimately make a real impact on patient care. So it’s going to be critical to find those quickly, translate them, and make them available.”

In the meantime, some answers might come from a large study sponsored by the National Institutes of Health. The NIH is funding the “Researching COVID to Enhance Recovery” project using $470 million from the American Rescue Plan. Investigators at NYU Langone Health are leading the effort and plan to share the wealth by funding more than 100 researchers at more than 30 institutions to create a “metacohort” to study long COVID. More information is available at recovercovid.org.

“Fortunately, through the global research effort, we are now really starting to expand our understanding of how long COVID manifests, how common it is, and what the underlying mechanisms may be,” Dr. Purpura said.

“A weakened immune response to an infection may mean that you have cryptic reservoirs of virus that are continuing to cause symptoms,” she said during the briefing. Dr. Hornig is a doctor-scientist specializing in epidemiology at Columbia University, New York.

“That may explain why some patients with long COVID feel better after vaccination,” because the vaccine creates a strong antibody response to fight COVID-19, Dr. Iwasaki said.

Researchers are unearthing additional potential factors contributing to long COVID.

Viral persistence could also reactivate other dormant viruses in the body, such as Epstein-Barr virus (EBV), said Lawrence Purpura, MD, MPH, an infectious disease specialist at New York Presbyterian/Columbia University. Reactivation of Epstein-Barr is one of four identifying signs of long COVID revealed in a Jan. 25 study published in the journal Cell.
 

Immune overactivation also possible?

For other people with long COVID, it’s not the virus sticking around but the body’s reaction that’s the issue.

Investigators suggest autoimmunity plays a role, and they point to the presence of autoantibodies, for example.

When these autoantibodies persist, they can cause tissue and organ damage over time.

Other investigators are proposing “immune exhaustion” in long COVID because of similarities to chronic fatigue syndrome, Dr. Hornig said.

“It should be ‘all hands on deck’ for research into long COVID,” she said. “The number of disabled individuals who will likely qualify for a diagnosis of [chronic fatigue syndrome] is growing by the second.”
 

Forging ahead on future research

It’s clear there is more work to do. There are investigators working on banking tissue samples from people with long COVID to learn more, for example.

Also, finding a biomarker unique to long COVID could vastly improve the precision of diagnosing long COVID, especially if the dog sniffing option does not pan out.

Of the thousands of biomarker possibilities, Dr. Hornig said, “maybe that’s one or two that ultimately make a real impact on patient care. So it’s going to be critical to find those quickly, translate them, and make them available.”

In the meantime, some answers might come from a large study sponsored by the National Institutes of Health. The NIH is funding the “Researching COVID to Enhance Recovery” project using $470 million from the American Rescue Plan. Investigators at NYU Langone Health are leading the effort and plan to share the wealth by funding more than 100 researchers at more than 30 institutions to create a “metacohort” to study long COVID. More information is available at recovercovid.org.

“Fortunately, through the global research effort, we are now really starting to expand our understanding of how long COVID manifests, how common it is, and what the underlying mechanisms may be,” Dr. Purpura said.

The indication of an Omicron decline has become a trend: New cases of COVID-19 in children were down for a second consecutive week in the United States, according to the American Academy of Pediatrics and the Children’s Hospital Association.

The total for the week of Jan. 28 to Feb. 3 was still “extremely high, over double the peak level of the Delta surge in 2021,” the AAP noted, but the nearly 632,000 cases reported were down by 22% from the previous week and by 45% from what appears to be the peak of the Omicron surge during the week of Jan. 14-20, the AAP/CHA data show.

To put the effect of the Delta and Omicron variants into some sort of perspective, the total number of COVID-19 cases among children passed 5 million at the beginning of September 2021, about a year and a half into the pandemic. In the last 5 months, the cumulative count has more than doubled and now stands at 12 million, the AAP and CHA said in their weekly COVID report.

Hospital admissions and emergency department visits followed the same downward trend over the last week. The rate of new hospitalizations fell to 0.81 per 100,000 children aged 0-17 years as of Feb. 2 (down from a peak of 1.25 per 100,000 on Jan. 15), and ED visits with diagnosed COVID-19 dropped to 1.8% (peak was 14.1%), 1.9% (peak was 14.3%), and 3.4% (peak was 14%) of all visits for children aged 16-17, 12-15, and 0-11 years, respectively, the Centers for Disease Control and Prevention reported.

The vaccination response

The surge of infections brought about by the Omicron variant, however, did not translate into increased vaccination, at least for the youngest eligible children. Vaccine initiation rose slightly among children aged 5-11 in early and mid-January but, by early February, new vaccinations had declined to their lowest point since approval in early November of 2021, the AAP said in its weekly COVID vaccination report.

As a result, the 5- to 11-year-olds are well behind the pace set by those aged 12-15 for the first 3 months of their vaccination experience. Through the first 13 weeks after the COVID vaccine was approved for children aged 12-15 in early May, 44.5% had received at least one dose and 32.3% were fully vaccinated. Among children aged 5-11, the corresponding figures through 13 weeks were 31% and 22.5%, according to CDC data.

The vaccination reaction to Omicron was somewhat more robust for children aged 12-17, compared with the younger group, but initiations dropped at the same time that new cases began to decline. In terms of total volume, the response among 12- to 17-year-olds was much smaller than that seen in July and August of 2021 as the Delta surge was hitting the United States, the AAP vaccination report shows.

All those vaccinations add up to this: Over 16.8 million children aged 12-17 and almost 9 million aged 5-11 had received at least one dose of vaccine as of Feb. 7, which works out to 66.6% of the older group and 31.2% of the younger cohort. Almost 14.3 million (56.4%) of those aged 12-17 are fully vaccinated, as are 6.6 million (22.9%) of the 5- to 11-year-olds, the CDC said on its COVID Data Tracker.

Long COVID continues to be a moving target – continuously evolving and still surprising doctors and patients who have sometimes incapacitating long-term symptoms.

Little about the disorder seems predictable at this point. People can have long COVID after asymptomatic, mild, or severe COVID-19, for example. And when a person gets long COVID – also known as long-haul COVID – symptoms can vary widely.

To address all the uncertainty, the New York State Department of Health gathered experts in primary care, pediatrics, physical medicine, rehabilitation, and pulmonology to answer some pressing questions.

New York in 2020 was the first epicenter of the pandemic in the United States, making it also the center of the long COVID epidemic, says Emily Lutterloh, MD, director of the Division of Epidemiology at the New York State Department of Health.
 

What do you do when you’re seeing a patient with long COVID for the first time?

The first exam varies because there are so many different ways long COVID presents itself, says Benjamin Abramoff, MD, a physical medicine and rehabilitation specialist at Penn Medicine in Philadelphia.

I’ve now been seriously ill with #LongCovid for 11 months. I was never hospitalized. I didn’t even have a “mild” covid case. Instead, I developed Long Covid from an asymptomatic infection.

I’m far from unique. Up to 1/5 of asymptomatic patients go on to have long-term symptoms.

— Ravi Veriah Jacques (@RaviHVJ) February 3, 2022

Assessing their previous and current care also helps to direct their ongoing management, says Zijian Chen, MD, medical director of the Center for Post-COVID Care at Mount Sinai Health System in New York.
 

Can vaccination help people with long COVID?

Anything that we can do to help prevent people from being critically ill or being hospitalized with COVID-19 is helpful to prevent long COVID, says Dr. Abramoff, who is also director of the long COVID clinic at the University of Pennsylvania, Philadelphia.

“So that’s something I always discuss with patients. In some research, sometimes patients do feel better after the vaccine,” he says.
 

What kind of therapies do you find helpful for your patients?

Rehabilitation is a key part of recovery from long COVID, Dr. Abramoff says. “It is very important to make this very patient-specific.”

“We have patients that are working. They’re already going to the gym in some cases but don’t feel like they have the same endurance,” he says. “And then we have patients who are so crippled by their fatigue that they can’t get out of bed.”

An exercise program can help people who have long COVID.

“There’s a big role for therapy services in the recovery of these patients,” says John Baratta, MD, of the department of physical medicine and rehabilitation at the University of North Carolina at Chapel Hill.

But the limited number of long COVID clinics can mean some people are unable to get to therapists trained on the needs of patients with lingering COVID symptoms. Educating community physical and occupational therapists is one solution.
 

How long does it take for people with long COVID to recover and get back to 100% if they can?

Specific numbers aren’t really available, Dr. Baratta says.

“But I can tell you the general trend that I see is that a lot of patients have a gradual improvement of symptoms. The slow but steady improvement with time may be the body’s natural healing process, a result of medical interventions, or both.”

It can help to reassure people with long COVID that they will not be discharged from care until they feel they’ve maximized their health, says Sharagim Kemp, DO, medical director of the COVID Recovery Program for Nuvance Health, a health system in New York and Connecticut.

It’s essential to set realistic recovery expectations and tell patients that not everyone will return to 100% of their pre-COVID functioning, she says.

“Once we are able to help them reset their expectations, there’s almost an accelerated recovery because they are not putting that pressure on themselves anymore,” Dr. Kemp says.
 

What are the most common symptoms you’re seeing in long COVID?

It’s helpful to think of long COVID as a very broad umbrella term, Dr. Abramoff says.

Echoing what many others have observed, fatigue, cognitive dysfunction or “brain fog,“ and shortness of breath or troubled breathing appear to be the most common symptoms, he says.

Some reported vague symptoms, Dr. Kemp says.

People may go to the doctor “not even realizing that they had COVID. That’s one of the important points here – to have a high index of suspicion for patients who come in with multiple symptoms,” she says.

For this reason, patients can report symptoms that don’t necessarily fit into any specialty, says Sarah J. Ryan, MD, an internal medicine doctor at Columbia University Irving Medical Center in New York. People say they are “just not themselves” or they are tired after their COVID-19 recovery.
 

Is there a connection between severe COVID cases and severe long COVID?

“It’s not like that at all. I would say that more than 80% of the patients that we see had mild to moderate illness and they were not hospitalized,” Dr. Baratta says.

Long COVID is a bit different in children and teenagers, says Ixsy Ramirez, MD, a pediatric pulmonologist at University of Michigan Health, Ann Arbor. Most patients in the long COVID clinic at the University of Michigan were previously healthy, and not children with asthma or other lung conditions as one might expect. In fact, many are student athletes, or were before they had long COVID.

In this population, shortness of breath is most common, followed by chest pain and fatigue. Unfortunately, the symptoms are so serious for many kids that their performance is limited, even if they can return to competitive play.
 

Are there defined criteria you use to diagnose long COVID? How do you give someone a diagnosis?

That’s an ever-evolving question, Dr. Kemp says. The generally accepted definition centers on persistent or new symptoms 4 weeks or more after the original COVID-19 illness, but there are exceptions.

Researchers are working on lab tests to help confirm the diagnosis. But without a definitive blood biomarker, getting to the diagnosis requires “some thorough detective work,” Dr. Ryan says.
 

Do you bring in mental health providers to help with treatment?

“We focus on mental health quite a bit actually,” says, Dr. Chen, cofounder of his institution’s COVID recovery clinic. Mount Sinai offers one-on-one and group mental health services, for example.

“Personally, I’ve seen patients that I did not expect to have such severe mental health changes” with long COVID.
 

One of the most powerful accounts and testimonies I have seen on what most #LongCovid patients experience when interacting with their doctors.

Examples include severe depression, cases of acute psychosis, hallucinations, and other problems “that are really unexpected after a viral illness.”

Stony Brook University Hospital in New York has a long COVID clinic staffed by multiple primary care doctors who do exams and refer patients to services. A bonus of offering psychological services to all post-COVID patients is doctors get a more complete picture of each person and a better understanding of what they are going through, says Abigail Chua, MD, a pulmonologist at Stony Brook.

Some empathy is essential, Dr. Baratta says. “It’s important to recognize that a lot of these patients present with a sense of grief or loss for their prior life.”
 

What does the future hold?

A simple test to diagnose long COVID, combined with an effective treatment that helps people feel better within a week, would be ideal, Dr. Abramoff says.

“That would be lovely. But you know, we’re just not at that point.”

And it would be helpful to start identifying subtypes of long COVID so diagnosis and treatment can be more targeted, Dr. Abramoff says. Otherwise, “It’s going to be a very challenging approach to try to treat all of our patients with long COVID symptoms the same way.”

Good clinical trials likewise are needed to address all the subtleties of long COVID.

A number of long COVID centers are collaborating on research to find out more, Dr. Chen says. Actions include setting up a bank of tissue samples from people with long COVID so researchers can continue to figure out the condition.

One goal, Dr. Chen says, would be the ability to treat long COVID rather than just its symptoms.

Long COVID emphasizes the need to prevent people from getting COVID in the first place, Dr. Ramirez says. This will continue to be important, particularly when some people dismiss the seriousness of COVID, comparing it to a cold if they get it. That attitude discounts the large number of people who unfortunately go on to develop long-term, often debilitating, symptoms.

Rehabilitation is a key part of recovery from long COVID, Dr. Abramoff says. “It is very important to make this very patient-specific.”

“We have patients that are working. They’re already going to the gym in some cases but don’t feel like they have the same endurance,” he says. “And then we have patients who are so crippled by their fatigue that they can’t get out of bed.”

An exercise program can help people who have long COVID.

“There’s a big role for therapy services in the recovery of these patients,” says John Baratta, MD, of the department of physical medicine and rehabilitation at the University of North Carolina at Chapel Hill.

But the limited number of long COVID clinics can mean some people are unable to get to therapists trained on the needs of patients with lingering COVID symptoms. Educating community physical and occupational therapists is one solution.
 

How long does it take for people with long COVID to recover and get back to 100% if they can?

Specific numbers aren’t really available, Dr. Baratta says.

“But I can tell you the general trend that I see is that a lot of patients have a gradual improvement of symptoms. The slow but steady improvement with time may be the body’s natural healing process, a result of medical interventions, or both.”

It can help to reassure people with long COVID that they will not be discharged from care until they feel they’ve maximized their health, says Sharagim Kemp, DO, medical director of the COVID Recovery Program for Nuvance Health, a health system in New York and Connecticut.

It’s essential to set realistic recovery expectations and tell patients that not everyone will return to 100% of their pre-COVID functioning, she says.

“Once we are able to help them reset their expectations, there’s almost an accelerated recovery because they are not putting that pressure on themselves anymore,” Dr. Kemp says.
 

What are the most common symptoms you’re seeing in long COVID?

It’s helpful to think of long COVID as a very broad umbrella term, Dr. Abramoff says.

Echoing what many others have observed, fatigue, cognitive dysfunction or “brain fog,“ and shortness of breath or troubled breathing appear to be the most common symptoms, he says.

Some reported vague symptoms, Dr. Kemp says.

People may go to the doctor “not even realizing that they had COVID. That’s one of the important points here – to have a high index of suspicion for patients who come in with multiple symptoms,” she says.

For this reason, patients can report symptoms that don’t necessarily fit into any specialty, says Sarah J. Ryan, MD, an internal medicine doctor at Columbia University Irving Medical Center in New York. People say they are “just not themselves” or they are tired after their COVID-19 recovery.
 

Is there a connection between severe COVID cases and severe long COVID?

“It’s not like that at all. I would say that more than 80% of the patients that we see had mild to moderate illness and they were not hospitalized,” Dr. Baratta says.

Long COVID is a bit different in children and teenagers, says Ixsy Ramirez, MD, a pediatric pulmonologist at University of Michigan Health, Ann Arbor. Most patients in the long COVID clinic at the University of Michigan were previously healthy, and not children with asthma or other lung conditions as one might expect. In fact, many are student athletes, or were before they had long COVID.

In this population, shortness of breath is most common, followed by chest pain and fatigue. Unfortunately, the symptoms are so serious for many kids that their performance is limited, even if they can return to competitive play.
 

Are there defined criteria you use to diagnose long COVID? How do you give someone a diagnosis?

That’s an ever-evolving question, Dr. Kemp says. The generally accepted definition centers on persistent or new symptoms 4 weeks or more after the original COVID-19 illness, but there are exceptions.

Researchers are working on lab tests to help confirm the diagnosis. But without a definitive blood biomarker, getting to the diagnosis requires “some thorough detective work,” Dr. Ryan says.
 

Do you bring in mental health providers to help with treatment?

“We focus on mental health quite a bit actually,” says, Dr. Chen, cofounder of his institution’s COVID recovery clinic. Mount Sinai offers one-on-one and group mental health services, for example.

“Personally, I’ve seen patients that I did not expect to have such severe mental health changes” with long COVID.
 

One of the most powerful accounts and testimonies I have seen on what most #LongCovid patients experience when interacting with their doctors.

Examples include severe depression, cases of acute psychosis, hallucinations, and other problems “that are really unexpected after a viral illness.”

Stony Brook University Hospital in New York has a long COVID clinic staffed by multiple primary care doctors who do exams and refer patients to services. A bonus of offering psychological services to all post-COVID patients is doctors get a more complete picture of each person and a better understanding of what they are going through, says Abigail Chua, MD, a pulmonologist at Stony Brook.

Some empathy is essential, Dr. Baratta says. “It’s important to recognize that a lot of these patients present with a sense of grief or loss for their prior life.”
 

What does the future hold?

A simple test to diagnose long COVID, combined with an effective treatment that helps people feel better within a week, would be ideal, Dr. Abramoff says.

“That would be lovely. But you know, we’re just not at that point.”

And it would be helpful to start identifying subtypes of long COVID so diagnosis and treatment can be more targeted, Dr. Abramoff says. Otherwise, “It’s going to be a very challenging approach to try to treat all of our patients with long COVID symptoms the same way.”

Good clinical trials likewise are needed to address all the subtleties of long COVID.

A number of long COVID centers are collaborating on research to find out more, Dr. Chen says. Actions include setting up a bank of tissue samples from people with long COVID so researchers can continue to figure out the condition.

One goal, Dr. Chen says, would be the ability to treat long COVID rather than just its symptoms.

Long COVID emphasizes the need to prevent people from getting COVID in the first place, Dr. Ramirez says. This will continue to be important, particularly when some people dismiss the seriousness of COVID, comparing it to a cold if they get it. That attitude discounts the large number of people who unfortunately go on to develop long-term, often debilitating, symptoms.

A new, highly-virulent form of the HIV-1 virus has been discovered in the Netherlands by an international collaboration led by researchers at the University of Oxford’s Big Data Institute.

In a study published in the journal Science, researchers identified a VB variant (virulent subtype B) of HIV-1 linked to higher viral loads, increased transmissibility, and a faster decline in CD4 cell levels, leading to increased immune deficiency.

In light of the ongoing pandemic and current focus on SARS-CoV-19 virus variants such as Delta or Omicron, the discovery provides a salutary reminder that other viral pathogens, including those responsible for many long-standing endemic diseases, undergo a similar process of mutation.

Lead author Dr. Chris Wymant said: “Before this study, the genetics of the HIV virus were known to be relevant for virulence, implying that the evolution of a new variant could change its impact on health. Discovery of the VB variant demonstrated this, providing a rare example of the risk posed by viral virulence evolution.”
 

Global disease, local variants

Human immunodeficiency virus (HIV) infections affect around 38 million people worldwide, with more than half a million  people dying from AIDS-related illnesses each year. The disease-causing retroviruses, of which the HIV-1 virus is most common, destroy CD4+ T cells, causing immune deficiency and leading eventually to AIDS.

RNA viruses such as HIV-1 have long been a particular concern to scientists because their error-prone replication, lacking the error-correcting mechanisms of DNA, results in more spontaneous mutations and so a higher potential for acquiring new characteristics.

The VB variant of HIV-1 was first detected in samples from 2,461 HIV-positive people whose viral genomes were sequenced as part of the ongoing BEEHIVE project. Within this cohort, researchers identified 17 people with very highly elevated viral loads.

As 15 of these individuals came from the Netherlands, the researchers next examined virus gene data from 6,706 HIV-positive patients in a Dutch HIV cohort study (ATHENA), identifying a further 92 people carrying the same VB variant.

By analysing patterns of genetic variation in the samples, researchers estimated that the VB variant first emerged in the Netherlands in the late 1990s, occurring through de novo mutations rather than recombination. It spread more quickly than other HIV variants initially, but cases have been declining since around 2010, most likely due to the availability of more effective combination anti-retroviral treatments.
 

Increased virulence

The researchers found a number of differences in people infected with the VB variant compared with those infected by other HIV variants. Prior to starting anti-retroviral treatment, individuals with the VB variant were found to have:

Around a 3.5- to 5.5-fold increase in viral load (a marker for viral virulence)

Double the rate of CD4 cell decline compared with individuals with other subtype-B strains, even after adjusting for viral load

Increased risk of transmitting the virus (the study used the virus ‘local branching index’ as a proxy for transmissibility).

Reassuringly, after starting anti-retroviral treatment, individuals with the VB variant showed similar CD4 cell recovery and survival to individuals with other HIV variants. However, the authors emphasise that due of the more rapid decline in immune function with the VB variant, it is critical to identify VB-positive individuals early and start treatment promptly.

Senior author Professor Christophe Fraser explained: “Our findings emphasise the importance of World Health Organization guidance that individuals at risk of acquiring HIV have access to regular testing to allow early diagnosis, followed by immediate treatment.

“This limits the amount of time HIV can damage an individual’s immune system and jeopardise their health. It also ensures that HIV is suppressed as quickly as possible, which prevents transmission to other individuals.”

Samples from patients in the United States and Kenya show an increasing emergence of previously undetected vancomycin-resistant strains of Clostridioides difficile, sparking concern as recurrences in the treatment of C. difficile infection (CDI) continue to rise.

“Our results may help explain a decreasing effectiveness of antibiotic-based therapy in C. difficile infection, since a significant proportion of patients harboring strains with reduced susceptibility to vancomycin may not respond to treatment,” reported the authors in research published recently in Clinical Infectious Diseases.

The spread of the resistant strains “has serious public health implications, underscoring an urgent need for a comprehensive analysis of the circulating strains to help inform clinical decisions,” they added.

Commenting on the findings, Cornelius J. Clancy, MD, professor of medicine at the University of Pittsburgh, and chief of infectious diseases at the Veterans Affairs Pittsburgh Healthcare System, echoed the concern.

“The casual belief has been that [C. difficile] strains at most centers can be assumed to be vancomycin susceptible,” he told this news organization. “This study shows that this assumption can no longer be taken as a given.”

Dr. Clancy, who was not involved with this research, noted that “based on this study, there might be need for the Infectious Diseases Society of America and other organizations to offer guidance on generating good, quality surveillance data for C. difficile resistance.”

With C. difficile showing the ability to resist multiple antibiotics, drugs in the armamentarium to treat the infection have declined in recent years, and recurrences with the infection are reported in up to 25% of cases.

Oral vancomycin is recommended as the antibiotic of choice by the IDSA and the Society for Healthcare Epidemiology of America for severe as well as nonsevere cases of CDI, and although there are reports of nine vancomycin-resistant gene clusters, most involve Enterococcus.

To take a closer look at the prevalence of vancomycin-resistant C. difficile strains, first author Charles Darkoh, PhD, with the Center for Infectious Diseases at the University of Texas Health Science Center, Houston, and colleagues analyzed stool samples from patients with CDI, including 438 patients in Houston, taken between 2012 and 2017, and 98 in Nairobi, Kenya, taken in 2017.

They found that, among samples from patients in Houston, over the time period, 26% showed vancomycin nonsusceptible C. difficile isolates and 29% had isolates that were metronidazole resistant.

And among samples from the Nairobi patients, 67% harbored vancomycin-resistant isolates and 85% had isolates resistant to metronidazole.

Of note, the proportion of samples containing vancomycin-resistant C. difficile in the Houston patients showed a marked increase over time, from «complete absence» in 2012 to approximately 35% in 2017, the authors reported.

“These nonsusceptibility rates significantly exceeded prior reports from other studies conducted in the United States and Europe from 2011 to 2014, suggesting a lower percentage of resistance to both metronidazole and vancomycin,” the authors wrote.

Further experiments on mouse models infected with one of the vancomycin-resistant isolates showed that treatment with vancomycin failed to eradicate the infection, and 5-day survival was significantly lower after vancomycin treatment in those mice (25%) versus those infected with strains known to be vancomycin sensitive (50%).
 

Unrecognized genetic strains

Whole-genome sequencing of 10 of the resistant isolates showed no matches with gene clusters that have been previously recognized as being vancomycin resistant, suggesting the emergence of new clusters.

“Together, these results suggest unknown genetic elements associated with vancomycin nonsusceptibility in isolates circulating in the patient population,” the authors wrote.

Dr. Darkoh told this news organization that the research team is currently working to further investigate the patterns and mechanisms.

“We are currently working on a follow-up study for the next 5 years to find out how widespread this is,” he said. “We want to make sure it’s not necessarily just occurring in the settings we studied, and we also need to establish the mechanism of resistance.”

Further commenting on the results, Dr. Clancy noted that “the extent of resistance caught many in the field a bit off guard, as they are higher than previously reported.”

“The data are also concerning because most centers do not routinely test C. difficile for drug susceptibility.”

Dr. Clancy noted that “another immediately pressing need is to understand mechanisms of resistance. It was quite striking that vancomycin-resistant strains in this study did not carry vanA genes, pointing to previously unrecognized mechanisms of resistance.”

“As is often the case, antibiotic overuse was likely a factor in the resistances, with overtesting often leading to overtreatment of C. difficile,” Dr. Clancy said. “The situation may have been compounded by failure to appreciate how entrenched C. difficile resistance may be at certain hospitals, since widespread susceptibility testing is generally not routinely performed.”

As alternative treatments, Dr. Clancy pointed to the recent IDSA update, which included a stronger endorsement of fidaxomicin.

“Of course, there is also the need to assure that data on resistance to agents like fidaxomicin are generated going forward,” he noted.

The study was supported by was supported by National Institutes of Health, the National Institute of Allergy and Infectious Diseases, the Texas Medical Center Digestive Diseases Center, and the University of Texas Health Science Center. Dr. Darkoh has disclosed no relevant financial relationships. One coauthor received grant support from Merck, Entasis Pharmaceuticals, and MeMed Diagnostics. Dr. Clancy disclosed advisory board, consulting and/or research relationships with Merck, Qpex Biopharma, Shionogi, Astellas, Cidara, Scynexis, and Needham & Associates.

Bronchiolitis is the leading cause of infant hospitalizations in the United States and Europe, and almost one-third of these patients go on to develop asthma later in childhood.

But a multinational team of researchers has presented evidence that could avoid that outcome. They identified four different subtypes of bronchiolitis along with a decision tree that can determine which infants are most likely to develop asthma as they get older.

Reporting in the journal eClinical Medicine, Michimasa Fujiogi, MD, of Massachusetts General Hospital and Harvard University, Boston, and colleagues analyzed three multicenter prospective cohort studies that included a combined 3,081 infants hospitalized with severe bronchiolitis.

“This study added a base for the early identification of high-risk patients during early infancy,” Dr. Fujiogi said in an interview. “Using the prediction rule of this study, it is possible to identify groups at high risk of asthma during a critical period of airway development – early infancy.”

The researchers identified four clinically distinct and reproducible profiles of infants hospitalized for bronchiolitis:

• A: characterized by a history of breathing problems and eczema, rhinovirus infection, and low prevalence of respiratory syncytial virus (RSV) infection.
• B: characterized by the classic symptoms of wheezing and cough at presentation, a low prevalence of previous breathing problems and rhinovirus infection, and a high likelihood of RSV infection.
• C: the most severe group, characterized by inadequate oral intake, severe retraction at presentation, and longer hospital stays.
• D: the least ill group, with little history of breathing problems but inadequate oral intake with no or mild retraction.

Infants with profile A had the highest risk for developing asthma – more than 250% greater than with typical bronchiolitis. They were also older and were more likely to have parents who had asthma – and none had solo-RSV infection. In the overall analysis, the risk for developing asthma by age 6 or 7 was 23%.

The researchers stated that the decision tree accurately predicts the high-risk profile with high degrees of sensitivity and specificity. The decision tree used four predictors that together defined infants with profile A: RSV infection status, previous breathing problems, eczema, and parental asthma.

“Our data would facilitate the development of profile-specific prevention strategies for asthma – for example, modification of host response, prophylaxis for severe viral infection – by identifying asthma risk groups early in infancy,” Dr. Fujiogi said.

The study received funding from the National Institutes of Health. Dr. Fujiogi and coauthors have disclosed no relevant financial relationships.
