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.

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?

Adolescents and young adults who use e-cigarettes reported vaping cannabis, according to selected data from the national Population Assessment of Tobacco and Health (PATH) study.

Ruoyan Sun, PhD, an assistant professor at the University of Alabama at Birmingham, and colleagues examined results of PATH’s wave5 survey conducted from December 2018 to November 2019. PATH is a National Institutes of Health–Food and Drug Administration collaboration begun in 2013.

Their analysis, published online Feb. 7, 2022, in JAMA Pediatrics, evaluated the frequency of cannabis vaping across several age groups: 164 respondents ages 12-14; 919 participants ages 15-17; and 3,038 participants ages 18-24. Respondents included for analysis reported electronic nicotine product consumption in the past 30 days. In response to the question “When you have used an electronic product, how often were you using it to smoke marijuana, marijuana concentrates, marijuana waxes, THC, or hash oils?” 35.0% (95% confidence interval, 29.3%-41.2%) of current e-smokers aged 12-14 years said they had done so, as did 51.3% (95% CI, 47.7%-54.9%) of those aged 15-17 years and 54.6% (95% CI, 52.5%-56.7%) of young adults aged 18-24.

The prevalence of those who reported vaping cannabis every time they vaped was 3.1% (95% CI, 1.3%-6.9%) of youths aged 12-14 years, 6.7% (95% CI, 5.3%-8.6%) of youths aged 15-17 years, and 10.3% (95% CI, 9.0%-11.6%) of young adults aged 18-24.

Among children ages 12-14, 65% said they never vaped cannabis, while 48.7% and 45.4%, respectively, in the two older groups said they did.

“This is a very important finding and it mirrors what some of us have already seen in practice,” said pediatric pulmonologist S. Christy Sadreameli, MD, MHS, an assistant professor of pediatrics at John Hopkins University, Baltimore. “It is important for pediatricians to realize that dual use of cannabis and nicotine vaping, and exclusive use of cannabis vaping, are not uncommon. It informs how we ask questions and how we counsel our patients.” Dr. Sadreameli was not involved in the PATH study.

Overall, the survey participants were 56% male, with 24% of respondents identifying as Hispanic, 8% as non-Hispanic Black, 58% as non-Hispanic White, and 10% as of other race/ethnicity. The weighted proportion of current e-cigarette use was 3.0% (95% CI, 2.6%-3.4%) in youths ages 12-14 years, 14.4% (95% CI, 13.5%-15.3%) in those 15-17 years, and 26.2% (95% CI, 25.3%-27.1%) in young adults.

Other recent national surveys such as the National Institute on Drug Abuses’s Monitoring the Future are reporting a growing prevalence of youth cannabis vaping, Dr. Sun said. For example, the prevalence of cannabis vaping in the past 12-month period among grade 12 students grew from 9.5% in 2017 to 22.1% in 2020. Vaping cannabis was more prevalent among Hispanic teens than other ethnicities.

Vaping devices such as e-cigarettes, vaping pens, e-cigars, and e-hookahs can be used to inhale multiple substances, including nicotine, cannabis, and opium, Dr. Sun noted in an interview. “So in addition to asking about the behavior of vaping itself, pediatricians could pay more attention to what is being vaped in these devices.”

According to Dr. Sadreameli, vaping more than one substance at a time could potentially work synergistically to cause more harm, compared with one product alone. “The other aspect to consider is that vaping multiple types of products may increase the chance of harm from other components of the mixture,” she said. For instance, a lot of the e-cigarette or vaping use-associated lung injury (EVALI) cases have been linked to vitamin E acetate, which was found in certain cannabis formulations. “Anecdotally, most EVALI patients I’ve met seemed to report use of multiple products, including cannabis-containing and nicotine-containing products.”

Dr. Sadreameli added that some cannabis vapers will have other issues. “For example, there is a severe vomiting syndrome I’ve seen, which is induced by cannabis and improved by cessation from cannabis,” she said. “It is important for pediatricians to ask the right questions of their patients in order to better understand what they may be experiencing, provide counseling, and to help them.”

A related issue is cessation, she said. “For those working to achieve cessation from nicotine-based products, sometimes nicotine replacement therapies are helpful. However, cessation from cannabis-containing products is going to look different.”

Although the study did not yield information on the prevalence simultaneous nicotine/cannabis vaping, the authors suggested that some vapers may be combining substances. Previous studies may have modestly overestimated the prevalence of nicotine vaping given their finding that some current e-cigarette users reported vaping cannabis every time they vaped and may be vaping cannabis exclusively. “However, if some current users vaped nicotine and cannabis simultaneously, then overestimation of nicotine vaping would be smaller,” they wrote.

Future surveys on this area should contain detailed questions on nicotine and cannabis vaping, including the substance being vaped and the frequency and intensity of use, Dr. Sun said. “In addition, these surveys could examine some other substances that are being vaped, such as opium and cocaine.”

The PATH study is supported by the NIH, National Institute on Drug Abuse, Department of Health & Human Services, and the FDA’s Center for Tobacco Products. The authors and Dr. Sadreameli had no competing interests to disclose.

Overall, the survey participants were 56% male, with 24% of respondents identifying as Hispanic, 8% as non-Hispanic Black, 58% as non-Hispanic White, and 10% as of other race/ethnicity. The weighted proportion of current e-cigarette use was 3.0% (95% CI, 2.6%-3.4%) in youths ages 12-14 years, 14.4% (95% CI, 13.5%-15.3%) in those 15-17 years, and 26.2% (95% CI, 25.3%-27.1%) in young adults.

Other recent national surveys such as the National Institute on Drug Abuses’s Monitoring the Future are reporting a growing prevalence of youth cannabis vaping, Dr. Sun said. For example, the prevalence of cannabis vaping in the past 12-month period among grade 12 students grew from 9.5% in 2017 to 22.1% in 2020. Vaping cannabis was more prevalent among Hispanic teens than other ethnicities.

Vaping devices such as e-cigarettes, vaping pens, e-cigars, and e-hookahs can be used to inhale multiple substances, including nicotine, cannabis, and opium, Dr. Sun noted in an interview. “So in addition to asking about the behavior of vaping itself, pediatricians could pay more attention to what is being vaped in these devices.”

According to Dr. Sadreameli, vaping more than one substance at a time could potentially work synergistically to cause more harm, compared with one product alone. “The other aspect to consider is that vaping multiple types of products may increase the chance of harm from other components of the mixture,” she said. For instance, a lot of the e-cigarette or vaping use-associated lung injury (EVALI) cases have been linked to vitamin E acetate, which was found in certain cannabis formulations. “Anecdotally, most EVALI patients I’ve met seemed to report use of multiple products, including cannabis-containing and nicotine-containing products.”

Dr. Sadreameli added that some cannabis vapers will have other issues. “For example, there is a severe vomiting syndrome I’ve seen, which is induced by cannabis and improved by cessation from cannabis,” she said. “It is important for pediatricians to ask the right questions of their patients in order to better understand what they may be experiencing, provide counseling, and to help them.”

A related issue is cessation, she said. “For those working to achieve cessation from nicotine-based products, sometimes nicotine replacement therapies are helpful. However, cessation from cannabis-containing products is going to look different.”

Although the study did not yield information on the prevalence simultaneous nicotine/cannabis vaping, the authors suggested that some vapers may be combining substances. Previous studies may have modestly overestimated the prevalence of nicotine vaping given their finding that some current e-cigarette users reported vaping cannabis every time they vaped and may be vaping cannabis exclusively. “However, if some current users vaped nicotine and cannabis simultaneously, then overestimation of nicotine vaping would be smaller,” they wrote.

Future surveys on this area should contain detailed questions on nicotine and cannabis vaping, including the substance being vaped and the frequency and intensity of use, Dr. Sun said. “In addition, these surveys could examine some other substances that are being vaped, such as opium and cocaine.”

The PATH study is supported by the NIH, National Institute on Drug Abuse, Department of Health & Human Services, and the FDA’s Center for Tobacco Products. The authors and Dr. Sadreameli had no competing interests to disclose.

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.

In 1938, the year that cystic fibrosis (CF) was first described clinically, four of five children born with the disease did not live past their first birthdays.

In 2019, the median age at death for patients enrolled in the Cystic Fibrosis Foundation (CFF) registry was 32 years, and the predicted life expectancy for patients with CF who were born from 2015 through 2019 was 46 years.

Blausen.com staff (2014). "Medical gallery of Blausen Medical Blausen.com staff (2014). "Medical gallery of Blausen Medical 2014". WikiJournal of Medicine 1 (2). DOI:10.15347/wjm/2014.010. ISSN 2002-4436.

Those numbers reflect the remarkable progress made in the past 4 decades in the care of patients with CF, but also highlight the obstacles ahead, given that the predicted life expectancy for the overall U.S. population in 2019 (pre–COVID-19) was 78.9 years.

Julie Desch, MD, is a CF survivor who has beaten the odds and then some. At age 61, the retired surgical pathologist is a CF patient advocate, speaker, and a board member of the Cystic Fibrosis Research Institute, a not-for-profit organization that funds CF research and offers education, advocacy, and psychosocial support for persons with CF and their families and caregivers.

In an interview, Dr. Desch said that while there has been remarkable progress in her lifetime in the field of CF research and treatment, particularly in the development of drugs that modulate function of the underlying cause of approximately 90% of CF cases, there are still many CF patients who cannot benefit from these therapies.

“There are still 10% of people who don’t make a protein to be modified, so that’s a huge unmet need,” she said.
 

Genetic disorder

CF is a chronic autosomal recessive disorder with multiorgan and multisystem manifestations. It is caused by mutations in the CFTR gene, which codes for the protein CF transmembrane conductance regulator. CFTR controls transport of chloride ions across cell membranes, specifically the apical membrane of epithelial cells in tissues of the airways, intestinal tract, pancreas, kidneys, sweat glands, and the reproductive system, notably the vas deferens in males.

The F508 deletion (F508del) mutation is the most common, occurring in approximately 70% of persons with CF. It is a class 2-type protein processing mutation, leading to defects in cellular processing, protein stability, and chloride channel gating defects.

The CFTR protein also secretes bicarbonate to regulate the pH of airway surface liquid, and inhibits the epithelial sodium channel, which mediates passive sodium transport across apical membranes of sodium-absorbing epithelial cells in the kidneys, intestine, and airways.

CF typically presents with the buildup in the lungs of abnormally viscous and sticky mucus leading to frequent, severe infections, particularly with Pseudomonas aeruginosa, progressive lung damage and, prior to the development of effective disease management, to premature death. The phenotype often includes malnutrition due to malabsorption, and failure to thrive.
 

Diagnosis

In all 50 U.S. states and the District of Columbia, newborns are screened for CF with an assay for immunoreactive trypsinogen (IRT) an indirect marker for pancreatic injury that is elevated in serum in most newborns with CF, but also detected in premature infants or those delivered under stressful circumstances. In some states newborns are tested only for IRT, with a diagnosis confirmed with a sweat chloride test and/or a CFTR mutation panel.

Treatment

There is no cure for CF, but the discovery of the gene in 1989 by Canadian and U.S. investigators has led to life-prolonging therapeutic interventions, specifically the development of CFTR modulators.

CFTR modulators include potentiators such as ivacaftor (Kalydeco), and correctors such as lumacaftor and tezacaftor (available in the combination Orkambi), and most recently in the triple combination of elexacaftor, tezacaftor, and ivacaftor (Trikafta; ETI).

Neil Sweezey, MD, FRCPC, a CF expert at The Hospital for Sick Children (SickKids) in Toronto, told this news organization that the ideal therapy for CF, genetic correction of the underlying mutations, is still not feasible, but that CFTR modulators are a close second.

“For 90% of patients, the three-drug combination Trikafta has been shown to be quite safe, quite tolerable, and quite remarkably beneficial,” he said.

In a study reported at CHEST 2021 by investigators from Nationwide Children’s Hospital in Columbus, Ohio, 32 adults who were started on the triple combination had significantly improved in forced expiratory volume in 1 second (FEV₁), gain in body mass index, decreased sweat chloride and decreased colonization by Pseudomonas species. In addition, patients had significant improvements in blood inflammatory markers.

Christopher H. Goss, MD, FCCP, professor of pulmonary critical care and sleep medicine and professor of pediatrics at the University of Washington in Seattle, agreed that with the availability of the triple combination, “these are extraordinary times. An astounding fact is that most patients have complete resolution of cough, and the exacerbation rates have just plummeted,” he said in an interview.

Some of the reductions in exacerbations may be attributable to the COVID-19 pandemic, he noted, because patients in isolation have less exposure to circulating respiratory viruses.

“But it has been miraculous, and the clinical effect is certainly still more astounding than the effects of ivacaftor, which was the first truly breakthrough drug. Weight goes up, well-being increases, and the population lung function has shifted up to better grade lung function, in the entire population,” he said.

In addition, the need for lung and heart transplantation has sharply declined.

“I had a patient who had decided to forgo transplantation, despite absolutely horrible lung function, and he’s now bowling and leading a very productive life, when before he had been preparing for end of life,” Dr. Goss said.

Dr. Sweezey emphasized that as with all medications, patients being started on the triple combination require close monitoring for potential adverse events that might require dose modification or, for a small number of patients, withdrawal.


 

Burden of care

CFTR modulators have reduced but not eliminated the need for some patients to have mucolytic therapy, which may include dornase alfa, a recombinant human deoxyribonuclease (DNase) that reduces the viscosity of lung secretions, hypertonic saline inhaled twice daily (for patients 12 and older), mannitol, and physical manipulations to help patients clear mucus. This can include both manual percussion and the use of devices for high-frequency chest wall oscillation.

The complex nature of CF often requires a combination of other therapies to address comorbidities. These therapies may include infection prophylaxis and treatment with antibiotics and antifungals, nutrition support, and therapy for CF-related complications, including gastrointestinal issues, liver diseases, diabetes, and osteopenia that may be related to poor nutrient absorption, chronic inflammation, or other sequelae of CF.

In addition, patients often require frequent CF care center visits – ideally a minimum of every 3 months – which can result in significant loss of work or school time.

“Outcomes for patients in the long run have been absolutely proven to be best if they’re followed in big, established, multidisciplinary well-organized CF centers,” Dr. Sweezey said. “In the United States and Canada if you’re looked after on a regular basis, which means quarterly, every 3 months – whether you need it or not, you really do need it – and if the patients are seen and assessed and checked every 3 months all of their lives, they have small changes caught early, whether it’s an infection you can slap down with medication or a nutrition problem that may be affecting a child’s growth and development.”

“We’re really kind of at a pivotal moment in CF, where we realize things are changing,” said A. Whitney Brown, MD, senior director for clinical affairs at the Cystic Fibrosis Foundation, and an adult CF and lung transplant physician in the Inova Advanced Lung Disease Program in Falls Church, Va.

“Patient needs and interest have evolved, because of the pandemic and because of the highly effective modulator therapy, but we want to take great effort to study it in a rigorous way, to make sure that as we are agile and adapt the care model, that we can maintain the same quality outcomes that we have traditionally done,” she said in an interview.

The Lancet Respiratory Medicine Commission on the future of CF care states that models of care “need to consider management approaches (including disease monitoring) to maintain health and delay lung transplantation, while minimizing the burden of care for patients and their families.”
 

‘A great problem to have’

One of the most significant changes in CF care has been the growing population of CF patients like Dr. Desch who are living well into adulthood, with some approaching Medicare eligibility.

With the advent of triple therapy and CFTR modulators being started earlier in life, lung function can be preserved, damage to other organs can be minimized, and life expectancy for patients with CF will continue to improve.

“We’re anticipating that there may be some needs in the aging CF population that are different than what we have historically had,” Dr. Brown said. “Will there be geriatric providers that need to become experts in CF care? That’s a great problem to have,” she said.

Dr. Goss agreed, noting that CF is steadily shifting from a near uniformly fatal disease to a chronic disorder that in many cases can be managed “with a complex regimen of novel drugs, much like HIV.”

He noted that there are multiple drug interactions with the triple combination, “so it’s really important that people don’t start a CF patient on a drug without consulting a pharmacist, because you can totally inactivate ETI, or augment it dramatically, and we’ve seen both happen.”
 

Cost and access

All experts interviewed for this article agreed that while the care of patients with CF has improved exponentially over the last few decades, there are still troubling inequities in care.

One of the largest impediments is the cost of care, with the triple combination costing more than $300,000 per year.

“Clearly patients aren’t paying that, but insurance companies are, and that’s causing all kinds of trickle-down effects that definitely affect patients. The patients like myself who are able to have insurance that covers it benefit, but there are so many people that don’t,” Dr. Desch said.

Dr. Sweezey noted that prior to the advent of ETI, patients with CF in Canada had better outcomes and longer life expectancy than did similar patients in the United States because of universal access to care and coordinated services under Canada’s health care system, compared with the highly fragmented and inefficient U.S. system. He added that the wider availability of ETI in the United States vs. Canada may begin to narrow that gap, however.

As noted before, there is a substantial proportion of patients – an estimated 10% – who have CFTR mutations that are not correctable by currently available CFTR modulators, and these patients are at significant risk for irreversible airway complications and lung damage.

In addition, although CF occurs most frequently among people of White ancestry, the disease does not respect distinctions of race or ethnicity.

“It’s not just [Whites] – a lot of people from different racial backgrounds, ethnic backgrounds, are not being diagnosed or are not being diagnosed soon enough to have effective care early enough,” Dr. Desch said.

That statement is supported by the Lancet Respiratory Medicine Commission on the future of cystic fibrosis care, whose members noted in 2019 that “epidemiological studies in the past 2 decades have shown that cystic fibrosis occurs and is more frequent than was previously thought in populations of non-European descent, and the disease is now recognized in many regions of the world.”

The commission members noted that the costs of adequate CF care may be beyond the reach of many patients in developing nations.

Still, if the substantial barriers of cost and access can be overcome, the future will continue to look brighter for patients with CF. As Dr. Sweezey put it: “There are studies that are pushing lower age limits for using these modulators, and as the evidence builds for the efficacy and safety at younger ages, I think all of us are hoping that we’ll end up being able to use either the current or future modulators to actually prevent trouble in CF, rather than trying to come along and fix it after it’s been there.”

Dr. Brown disclosed advisory board activity for Vertex that ended prior to her joining the CF Foundation. Dr. Desch, Dr. Goss, and Dr. Sweezey reported no relevant conflicts of interest.

Goss, MD, FCCP, professor of pulmonary critical care and sleep medicine and professor of pediatrics at the University of Washington in Seattle, agreed that with the availability of the triple combination, “these are extraordinary times. An astounding fact is that most patients have complete resolution of cough, and the exacerbation rates have just plummeted,” he said in an interview.

Some of the reductions in exacerbations may be attributable to the COVID-19 pandemic, he noted, because patients in isolation have less exposure to circulating respiratory viruses.

“But it has been miraculous, and the clinical effect is certainly still more astounding than the effects of ivacaftor, which was the first truly breakthrough drug. Weight goes up, well-being increases, and the population lung function has shifted up to better grade lung function, in the entire population,” he said.

In addition, the need for lung and heart transplantation has sharply declined.

“I had a patient who had decided to forgo transplantation, despite absolutely horrible lung function, and he’s now bowling and leading a very productive life, when before he had been preparing for end of life,” Dr. Goss said.

Dr. Sweezey emphasized that as with all medications, patients being started on the triple combination require close monitoring for potential adverse events that might require dose modification or, for a small number of patients, withdrawal.


 

Burden of care

CFTR modulators have reduced but not eliminated the need for some patients to have mucolytic therapy, which may include dornase alfa, a recombinant human deoxyribonuclease (DNase) that reduces the viscosity of lung secretions, hypertonic saline inhaled twice daily (for patients 12 and older), mannitol, and physical manipulations to help patients clear mucus. This can include both manual percussion and the use of devices for high-frequency chest wall oscillation.

The complex nature of CF often requires a combination of other therapies to address comorbidities. These therapies may include infection prophylaxis and treatment with antibiotics and antifungals, nutrition support, and therapy for CF-related complications, including gastrointestinal issues, liver diseases, diabetes, and osteopenia that may be related to poor nutrient absorption, chronic inflammation, or other sequelae of CF.

In addition, patients often require frequent CF care center visits – ideally a minimum of every 3 months – which can result in significant loss of work or school time.

“Outcomes for patients in the long run have been absolutely proven to be best if they’re followed in big, established, multidisciplinary well-organized CF centers,” Dr. Sweezey said. “In the United States and Canada if you’re looked after on a regular basis, which means quarterly, every 3 months – whether you need it or not, you really do need it – and if the patients are seen and assessed and checked every 3 months all of their lives, they have small changes caught early, whether it’s an infection you can slap down with medication or a nutrition problem that may be affecting a child’s growth and development.”

“We’re really kind of at a pivotal moment in CF, where we realize things are changing,” said A. Whitney Brown, MD, senior director for clinical affairs at the Cystic Fibrosis Foundation, and an adult CF and lung transplant physician in the Inova Advanced Lung Disease Program in Falls Church, Va.

“Patient needs and interest have evolved, because of the pandemic and because of the highly effective modulator therapy, but we want to take great effort to study it in a rigorous way, to make sure that as we are agile and adapt the care model, that we can maintain the same quality outcomes that we have traditionally done,” she said in an interview.

The Lancet Respiratory Medicine Commission on the future of CF care states that models of care “need to consider management approaches (including disease monitoring) to maintain health and delay lung transplantation, while minimizing the burden of care for patients and their families.”
 

‘A great problem to have’

One of the most significant changes in CF care has been the growing population of CF patients like Dr. Desch who are living well into adulthood, with some approaching Medicare eligibility.

With the advent of triple therapy and CFTR modulators being started earlier in life, lung function can be preserved, damage to other organs can be minimized, and life expectancy for patients with CF will continue to improve.

“We’re anticipating that there may be some needs in the aging CF population that are different than what we have historically had,” Dr. Brown said. “Will there be geriatric providers that need to become experts in CF care? That’s a great problem to have,” she said.

Dr. Goss agreed, noting that CF is steadily shifting from a near uniformly fatal disease to a chronic disorder that in many cases can be managed “with a complex regimen of novel drugs, much like HIV.”

He noted that there are multiple drug interactions with the triple combination, “so it’s really important that people don’t start a CF patient on a drug without consulting a pharmacist, because you can totally inactivate ETI, or augment it dramatically, and we’ve seen both happen.”
 

Cost and access

All experts interviewed for this article agreed that while the care of patients with CF has improved exponentially over the last few decades, there are still troubling inequities in care.

One of the largest impediments is the cost of care, with the triple combination costing more than $300,000 per year.

“Clearly patients aren’t paying that, but insurance companies are, and that’s causing all kinds of trickle-down effects that definitely affect patients. The patients like myself who are able to have insurance that covers it benefit, but there are so many people that don’t,” Dr. Desch said.

Dr. Sweezey noted that prior to the advent of ETI, patients with CF in Canada had better outcomes and longer life expectancy than did similar patients in the United States because of universal access to care and coordinated services under Canada’s health care system, compared with the highly fragmented and inefficient U.S. system. He added that the wider availability of ETI in the United States vs. Canada may begin to narrow that gap, however.

As noted before, there is a substantial proportion of patients – an estimated 10% – who have CFTR mutations that are not correctable by currently available CFTR modulators, and these patients are at significant risk for irreversible airway complications and lung damage.

In addition, although CF occurs most frequently among people of White ancestry, the disease does not respect distinctions of race or ethnicity.

“It’s not just [Whites] – a lot of people from different racial backgrounds, ethnic backgrounds, are not being diagnosed or are not being diagnosed soon enough to have effective care early enough,” Dr. Desch said.

That statement is supported by the Lancet Respiratory Medicine Commission on the future of cystic fibrosis care, whose members noted in 2019 that “epidemiological studies in the past 2 decades have shown that cystic fibrosis occurs and is more frequent than was previously thought in populations of non-European descent, and the disease is now recognized in many regions of the world.”

The commission members noted that the costs of adequate CF care may be beyond the reach of many patients in developing nations.

Still, if the substantial barriers of cost and access can be overcome, the future will continue to look brighter for patients with CF. As Dr. Sweezey put it: “There are studies that are pushing lower age limits for using these modulators, and as the evidence builds for the efficacy and safety at younger ages, I think all of us are hoping that we’ll end up being able to use either the current or future modulators to actually prevent trouble in CF, rather than trying to come along and fix it after it’s been there.”

Dr. Brown disclosed advisory board activity for Vertex that ended prior to her joining the CF Foundation. Dr. Desch, Dr. Goss, and Dr. Sweezey reported no relevant conflicts of interest.

In 1938, the year that cystic fibrosis (CF) was first described clinically, four of five children born with the disease did not live past their first birthdays.

In 2019, the median age at death for patients enrolled in the Cystic Fibrosis Foundation (CFF) registry was 32 years, and the predicted life expectancy for patients with CF who were born from 2015 through 2019 was 46 years.

Those numbers reflect the remarkable progress made in the past 4 decades in the care of patients with CF, but also highlight the obstacles ahead, given that the predicted life expectancy for the overall U.S. population in 2019 (pre–COVID-19) was 78.9 years.

Julie Desch, MD, is a CF survivor who has beaten the odds and then some. At age 61, the retired surgical pathologist is a CF patient advocate, speaker, and a board member of the Cystic Fibrosis Research Institute, a not-for-profit organization that funds CF research and offers education, advocacy, and psychosocial support for persons with CF and their families and caregivers.

In an interview, Dr. Desch said that while there has been remarkable progress in her lifetime in the field of CF research and treatment, particularly in the development of drugs that modulate function of the underlying cause of approximately 90% of CF cases, there are still many CF patients who cannot benefit from these therapies.

“There are still 10% of people who don’t make a protein to be modified, so that’s a huge unmet need,” she said.
 

Genetic disorder

CF is a chronic autosomal recessive disorder with multiorgan and multisystem manifestations. It is caused by mutations in the CFTR gene, which codes for the protein CF transmembrane conductance regulator. CFTR controls transport of chloride ions across cell membranes, specifically the apical membrane of epithelial cells in tissues of the airways, intestinal tract, pancreas, kidneys, sweat glands, and the reproductive system, notably the vas deferens in males.

The F508 deletion (F508del) mutation is the most common, occurring in approximately 70% of persons with CF. It is a class 2-type protein processing mutation, leading to defects in cellular processing, protein stability, and chloride channel gating defects.

The CFTR protein also secretes bicarbonate to regulate the pH of airway surface liquid, and inhibits the epithelial sodium channel, which mediates passive sodium transport across apical membranes of sodium-absorbing epithelial cells in the kidneys, intestine, and airways.

CF typically presents with the buildup in the lungs of abnormally viscous and sticky mucus leading to frequent, severe infections, particularly with Pseudomonas aeruginosa, progressive lung damage and, prior to the development of effective disease management, to premature death. The phenotype often includes malnutrition due to malabsorption, and failure to thrive.
 

Diagnosis

In all 50 U.S. states and the District of Columbia, newborns are screened for CF with an assay for immunoreactive trypsinogen (IRT) an indirect marker for pancreatic injury that is elevated in serum in most newborns with CF, but also detected in premature infants or those delivered under stressful circumstances. In some states newborns are tested only for IRT, with a diagnosis confirmed with a sweat chloride test and/or a CFTR mutation panel.

Treatment

There is no cure for CF, but the discovery of the gene in 1989 by Canadian and U.S. investigators has led to life-prolonging therapeutic interventions, specifically the development of CFTR modulators.

CFTR modulators include potentiators such as ivacaftor (Kalydeco), and correctors such as lumacaftor and tezacaftor (available in the combination Orkambi), and most recently in the triple combination of elexacaftor, tezacaftor, and ivacaftor (Trikafta; ETI).

Neil Sweezey, MD, FRCPC, a CF expert at The Hospital for Sick Children (SickKids) in Toronto, told this news organization that the ideal therapy for CF, genetic correction of the underlying mutations, is still not feasible, but that CFTR modulators are a close second.

“For 90% of patients, the three-drug combination Trikafta has been shown to be quite safe, quite tolerable, and quite remarkably beneficial,” he said.

In a study reported at CHEST 2021 by investigators from Nationwide Children’s Hospital in Columbus, Ohio, 32 adults who were started on the triple combination had significantly improved in forced expiratory volume in 1 second (FEV₁), gain in body mass index, decreased sweat chloride and decreased colonization by Pseudomonas species. In addition, patients had significant improvements in blood inflammatory markers.

Christopher H. Goss, MD, FCCP, professor of pulmonary critical care and sleep medicine and professor of pediatrics at the University of Washington in Seattle, agreed that with the availability of the triple combination, “these are extraordinary times.

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.

A new tracer for use in PET imaging can detect more metastases in patients with cancer than the standard tracer, leading to predictions of a “paradigm shift” in this field.

The new tracer, 68Ga-FAPI (fibroblast activation protein inhibitor), detected more metastases in patients with lung cancer than the standard tracer, 18F-FDG (fluorodeoxyglucose), which has been in use for years.

The study by Chinese researchers was published in Radiology.

The team imaged 34 lung cancer patients with both 68Ga-FAPI and 18F-FDG. Performance was similar for primary tumors and for lung, liver, and adrenal gland metastases. However, FAPI imaging detected more metastases in the lymph nodes (356 vs. 320), brain (23 vs. 10), bone (109 vs. 91), and pleura (66 vs. 35). However, neither modality outperformed MRI for brain metastases, the researchers note.

An accompanying editorial concluded that 68Ga-FAPI PET/CT scanning marks “an important paradigm shift to more specific identification and characterization of a variety of cancers.”

“This may also mark the arrival of a new era in nuclear medicine where molecular imaging helps visualize and characterize the entire tumor burden in one setting,” write editorialists Francine Jacobson, MD, and Annick Van den Abbeele, MD, from Harvard University and Brigham and Women’s Hospital and the Dana Farber Cancer Center, in Boston.

This study was the one of the latest in a fast-growing body of literature reporting that tracers targeting FAP with a small-molecule inhibitor (FAPI) outperform FDG tracers, not just in lung cancer but across a broad range of cancers, including breast, hepatic, gastrointestinal, head-neck, gynecologic, and many other tumor types.

The possibilities aren’t limited to imaging, either. Several companies are planning trials to target FAP with radiopharmaceuticals.

FAP is associated with wound repair and is highly expressed by the fibroblasts tightly packed in with cancer cells, particularly in stroma-dense tumors. FAP is rarely expressed by healthy tissue.

The underlying idea is to deliver a radionuclide to cancer-associated fibroblasts, using either a positron emitter, such as gallium-68 (68Ga), for PET imaging or a beta particle or other short-radiation emitter to kill nearby cancer cells as part of treatment.

Targeting FAP holds the promise of PET imaging that is more selective for cancer than FDG. FDG resolution depends on glucose uptake, which is high in active tumors but is also high in inflamed tissues as well as in the brain, gastrointestinal tract, and other areas. Uptake by background tissue can make it difficult to distinguish tumors from their surroundings. FDG uptake can also be lower in small and indolent tumors.

On the therapy side, there’s hope that FAP targeting will lead to radiopharmaceuticals that work across tumor types, not just in specific cancers.
 

High interest in FAP

Overall, FAP “is a target of high interest for the whole medical oncology community. The preliminary data are good, but this will take a while” to get to market, said Jeremie Calais, MD, a nuclear medicine specialist and FAP researcher at the University of California, Los Angeles.

Interest in FAP as a radiopharmaceutical target is being driven by the success of two agents that have served as a kind of proof of concept, Dr. Calais said.

The first is Novartis’s 177Lu-PSMA-617, which was granted priority review by the U.S. Food and Drug Administration in September 2021 following phase 3 results that showed a progression-free survival benefit of about 5 months when added to standard of care for metastatic castration-resistant prostate cancer, as well as an overall survival benefit of 4 months.

PSMA-617 binds prostate cancer cells that express prostate-specific membrane antigen. The lutetium-177 (177Lu) bombards them with beta particles and gamma radiation.

FAP researchers are also encouraged by the success of 177Lu dotatate (Lutathera), from Advanced Accelerator Applications, which delivers the radionucleotide to gastroenteropancreatic neuroendocrine tumors that express somatostatin receptors.

The FDA approved this agent in 2018 in part on the basis of phase 3 results that found a 20-month progression-free survival of 65.2% when Lutathera was added to octreotide for metastatic disease vs. 10.8% when it wasn’t.

Novartis is now looking into developing FAP-targeted radiopharmaceuticals, along with Clovis and Point Biopharma, among others.

“That’s the key goal” of industry research, “more so than FAP as a diagnostic tool,” Dr. Calais commented to this news organization. There’s “huge potential” if it works out, he said, in part because it won’t be limited to one tumor type.

Clovis recently launched a phase 1/2 trial of its candidate, 177Lu-FAP-2286, for advanced/metastatic solid tumors.

In the company’s “luMIERE” trial, subjects will be infused with 68Ga-FAP-2286 to image the tumor. Once uptake is confirmed, they’ll be infused with 177Lu-FAP-2286 for treatment.

The two-step process – uptake confirmation, then treatment – is dubbed “theranostics” and is the standard approach for radiopharmaceutical therapy, Dr. Calais said.

His own team is working to confirm that imaging accurately reflects FAP expression in tumors by comparing preoperative imaging results with FAP expression on surgical specimens. So far, his team has found that they are strongly correlated.

FAPI PET imaging research is much farther along than therapeutic applications, with almost 200 research articles listed on PubMed in 2021, up from just 3 in 2018. One 2019 paper reported “remarkably high uptake and image contrast” across 28 cancers in 80 patients, including breast, esophagus, lung, pancreatic, head-neck, and colorectal tumors.

Imaging studies so far have tended to be small, with many currently focused on identifying the optimal molecule for targeting FAP and the best positron emitter to combine with it.

FAPI tracers are not available yet commercially, so researchers are creating them themselves. One team recently reported it’s recipe for automated synthesis using commercially available synthesis modules.

Sofie, a maker of FDG and other tracers, hopes to change that and is working to bring FAP tracers to market. The company announced in November 2021 a phase 2 study of 68Ga FAPI-46 to image pancreatic ductal adenocarcinoma. It’s the first step in a broader development program for oncologic and nononcologic indications, Sofie said in a press release.

Dr. Calais sees potential for indications where FAPI has already outperformed FDG in the literature, particularly for gastrointestinal cancers. He doesn’t think it will ever replace FDG for indications such as lymphoma, where it “works perfectly well.”

“On the other hand, you have lesions located in a tissue that has some background level” of FDG uptake. “These things are okay with FDG, but I think maybe FAP can help” because of the improved signal-to-noise ratio, Dr. Calais commented. Unlike FDG, “you mostly never see background uptake with FAP-imaging agents,” he said.

Other pluses include quicker distribution throughout the body than FDG, so scan times are shorter, and also patients do not need to fast beforehand.

Dr. Calais predicts that FAPI tracers will reach the market within 5 years.

A new tracer for use in PET imaging can detect more metastases in patients with cancer than the standard tracer, leading to predictions of a “paradigm shift” in this field.

The new tracer, 68Ga-FAPI (fibroblast activation protein inhibitor), detected more metastases in patients with lung cancer than the standard tracer, 18F-FDG (fluorodeoxyglucose), which has been in use for years.

The study by Chinese researchers was published in Radiology.

The team imaged 34 lung cancer patients with both 68Ga-FAPI and 18F-FDG. Performance was similar for primary tumors and for lung, liver, and adrenal gland metastases. However, FAPI imaging detected more metastases in the lymph nodes (356 vs. 320), brain (23 vs. 10), bone (109 vs. 91), and pleura (66 vs. 35). However, neither modality outperformed MRI for brain metastases, the researchers note.

An accompanying editorial concluded that 68Ga-FAPI PET/CT scanning marks “an important paradigm shift to more specific identification and characterization of a variety of cancers.”

“This may also mark the arrival of a new era in nuclear medicine where molecular imaging helps visualize and characterize the entire tumor burden in one setting,” write editorialists Francine Jacobson, MD, and Annick Van den Abbeele, MD, from Harvard University and Brigham and Women’s Hospital and the Dana Farber Cancer Center, in Boston.

This study was the one of the latest in a fast-growing body of literature reporting that tracers targeting FAP with a small-molecule inhibitor (FAPI) outperform FDG tracers, not just in lung cancer but across a broad range of cancers, including breast, hepatic, gastrointestinal, head-neck, gynecologic, and many other tumor types.

The possibilities aren’t limited to imaging, either. Several companies are planning trials to target FAP with radiopharmaceuticals.

FAP is associated with wound repair and is highly expressed by the fibroblasts tightly packed in with cancer cells, particularly in stroma-dense tumors. FAP is rarely expressed by healthy tissue.

The underlying idea is to deliver a radionuclide to cancer-associated fibroblasts, using either a positron emitter, such as gallium-68 (68Ga), for PET imaging or a beta particle or other short-radiation emitter to kill nearby cancer cells as part of treatment.

Targeting FAP holds the promise of PET imaging that is more selective for cancer than FDG. FDG resolution depends on glucose uptake, which is high in active tumors but is also high in inflamed tissues as well as in the brain, gastrointestinal tract, and other areas. Uptake by background tissue can make it difficult to distinguish tumors from their surroundings. FDG uptake can also be lower in small and indolent tumors.

On the therapy side, there’s hope that FAP targeting will lead to radiopharmaceuticals that work across tumor types, not just in specific cancers.
 

High interest in FAP

Overall, FAP “is a target of high interest for the whole medical oncology community. The preliminary data are good, but this will take a while” to get to market, said Jeremie Calais, MD, a nuclear medicine specialist and FAP researcher at the University of California, Los Angeles.

Interest in FAP as a radiopharmaceutical target is being driven by the success of two agents that have served as a kind of proof of concept, Dr. Calais said.

The first is Novartis’s 177Lu-PSMA-617, which was granted priority review by the U.S. Food and Drug Administration in September 2021 following phase 3 results that showed a progression-free survival benefit of about 5 months when added to standard of care for metastatic castration-resistant prostate cancer, as well as an overall survival benefit of 4 months.

PSMA-617 binds prostate cancer cells that express prostate-specific membrane antigen. The lutetium-177 (177Lu) bombards them with beta particles and gamma radiation.

Aggressive up-front combination therapy, more lofty treatment goals, and earlier and more frequent reassessments to guide treatment are improving care of patients with pulmonary arterial hypertension (PAH) while at the same time making it more complex.

A larger number of oral and generic treatment options have in some respects ushered in more management ease. But overall, “I don’t know if management of these patients has ever been more complicated, given the treatment options and strategies,” said Murali M. Chakinala, MD, professor of medicine at Washington University, St. Louis. “We’re always thinking through approaches.”

Diagnosis continues to be challenging given the rarity of PAH and its nonspecific presentation – and in some cases it’s now harder. Experts such as Dr. Chakinala are seeing increasing number of aging patients with left heart disease, chronic kidney disease, and other comorbidities who have significant precapillary pulmonary hypertension and who exhibit hemodynamics consistent with PAH, or group 1 PH.

The question experts face is, do such patients have “true PAH,” as do a reported 25-50 people per million, or do they have another type of PH in the classification schema – or a mixture?

Deciding which patients “really fit into group 1 and should be managed like group 1,” Dr. Chakinala said, requires clinical acumen and has important implications, as patients with PAH are the main beneficiaries of vasodilator therapy. Most other patients with PH will not respond to or tolerate such treatment.

“These older patients may be getting PAH through different mechanisms than our younger patients, but because we define PAH through hemodynamic criteria and by ruling out other obvious explanations, they all get lumped together,” said Dr. Chakinala. “We need to parse these patients out better in the future, much like our oncology colleagues are doing.”

Personalized medicine hopefully is the next horizon for this condition, characterized by severe remodeling of the distal pulmonary arteries. Researchers are pushing to achieve deep phenotyping, identify biomarkers and improve risk assessment tools.

And with 80 or so centers now accredited by the Pulmonary Hypertension Association as Pulmonary Hypertension Care Centers, referred patients are accessing clinical trials of new nonvasodilatory drugs. Currently available therapies improve hemodynamics and symptoms, and can slow disease progression, but are not truly disease modifying, sources say.

“The endothelin, nitric oxide, and prostacyclin pathways have been exhaustively studied and we now have great drugs for those pathways,” said Dr. Chakinala, who leads the PHA’s scientific leadership council. But “we’re not going to put a greater dent into this disease until we have new drugs that work on different biologic pathways.”
 

Diagnostic challenges

The diagnosis of PAH – a remarkably heterogeneous condition that encompasses heritable forms and idiopathic forms, and that comprises a broad mix of predisposing conditions and exposures, from scleroderma to methamphetamine use – is still too often missed or delayed. Delayed diagnoses and misdiagnoses of PAH and other types of PH have been reported in up to 85% of at-risk patients, according to a 2016 literature review.

Being able to pivot from thinking about common pulmonary ailments or heart failure to considering PAH is a key part of earlier diagnosis and better treatment outcomes. “If someone has unexplained dyspnea or if they’re treated for other lung diseases and are not improving, think about a screening echocardiogram,” said Timothy L. Williamson, MD, vice president of quality and safety and a pulmonary and critical care physician at the University of Kansas Health Center, Kansas City.

One of the most common reasons Dr. Chakinala sees for missed diagnoses are right heart catheterizations that are incomplete or misinterpreted. (Right heart catheterizations are required to confirm the diagnosis.) “One can’t simply measure pressures and stop,” he said. “We need the full hemodynamic profile to know that it’s truly precapillary PAH ... and we need proper interpretation of [elements like] the waveforms.”

The 2019 World Symposium on Pulmonary Hypertension shifted the definition of PH from an arbitrarily defined mean pulmonary arterial pressure of at least 25 mm Hg at rest (as measured by right heart catheterization) to a more scientifically determined mPAP of at least 20 mm Hg.

The classification document also requires pulmonary vascular resistance (PVR) of at least 3 Wood units in the definition of all forms of precapillary PH. PAH specifically is defined as the presence of mPAP of at least 20 mm Hg, PVR of at least 3 Wood units, and pulmonary arterial wedge pressure 15 mm Hg or less.
 

Trends in treatment

The value of initial combination therapy with an endothelin receptor antagonist (ERA) and a phosphodiesterase-5 (PDE5) inhibitor in treatment-naive PAH was cemented in 2015 by the AMBITION trial. The primary endpoint (death, PAH hospitalization, or unsatisfactory clinical response) occurred in 18%, 34%, and 28% of patients who were randomized, respectively, to combination therapy, monotherapy with the ERA ambrisentan, or monotherapy with the PDE-5 inhibitor tadalafil – and in 31% of the two monotherapy groups combined.

The trial reported a 50% reduction in the primary endpoint in the combination-therapy group versus the pooled monotherapy group, as well as greater reductions in N-terminal of the prohormone brain natriuretic peptide levels, more satisfactory clinical response and greater improvement in 6-minute walking distance.

In practice, a minority of patients – typically older patients with multiple comorbidities – still receive initial monotherapy with sequential add-on therapies based on tolerance, but “for the most part PAH patients will start on combination therapy, most commonly with a ERA and PDE5 inhibitor,” Dr. Chakinala said.

For patients who are not improving on the ERA-PDE5 inhibitor approach – typically those who remain in the intermediate-risk category for intermediate-term mortality – substitution of the PDE5 inhibitor with the soluble guanylate cyclase stimulator riociguat may be considered, he and Dr. Williamson said. Clinical improvement with this substitution was demonstrated in the REPLACE trial.

Experts at PH care centers are also utilizing triple therapy for patients who do not improve to low-risk status after 2-4 months of dual combination therapy. The availability of oral prostacyclin analogues (selexipag and treprostinil) makes it easier to consider adding these agents early on, Dr. Chakinala and Dr. Richardson said.

Patients who fall into the high-risk category, at any point, are still best managed with parenteral prostacyclin analogues, Dr. Chakinala said.

In general, said Dr. Williamson, who also directs the University of Kansas Pulmonary Hypertension Comprehensive Care Center, “the PH community tends to be fairly aggressive up front, and with a low threshold for using prostacyclin analogues.”

The agents are “always part of the picture for someone who is really ill, in functional class IV, or has really impaired right ventricular function,” he said. “And we’re finding increased roles in patients who are not as ill but still have decompensated right ventricular dysfunction. It’s something we now consider.”

Recently published research on up-front oral triple therapy suggests possible benefit for some patients – but it’s far from conclusive, said Dr. Chakinala. The TRITON study randomized treatment-naive patients to the traditional ERA-PDE5 combination and either oral selexipag (a selective prostacyclin receptor agonist) or placebo as a third agent. It found no significant difference in reduction in PVR, the primary outcome, at week 26. However, the authors reported a “possible signal” for improved long-term outcomes with triple therapy.

“Based on this best evidence from a randomized clinical trial, I think it’s unfair to say that all patients should be on triple combination therapy right out of the gate,” he said. “Having said that, more recent [European] data showed that two drugs fell short of the mark in some patients, with high rates of clinical progression. And even in AMBITION, there were a number of patients in the combination arm who didn’t have a robust response.”

A 2021 retrospective analysis from the French Pulmonary Hypertension Registry – one of the European studies – assessed survival with monotherapy, dual therapy, or triple-combination therapy (two orals with a parenteral prostacyclin), and found no difference between monotherapy and dual therapy in high-risk patients.

Experts have been upping the ante, therefore, on early assessment and frequent reassessment of treatment response. Not long ago, patients were typically reassessed 6-12 months after the initiation of treatment. Now, experts at the PH care centers want to assess patients at 3-4 months and adjust or intensify treatment regimens for those who don’t yet qualify as low risk using a multidimensional risk score calculator.

The REVEAL (Registry to Evaluate Early and Long-Term PAH Management) risk score calculator, for instance, predicts the probability of 1-year survival and assigns patients to a strata of risk level based on either 12 or 6 variables (for the full or “lite” versions).]

Even better monitoring and risk assessment is needed, however, to “help sift out which patients are not improving enough on initial therapy or who are starting to fall off after being on a regimen for a period of time,” Dr. Chakinala said.

Today, with a network of accredited centers of expertise and a desire and need for many patients to remain close to home, Dr. Chakinala encourages finding a balance. Well-resourced clinicians can strive for early diagnosis and management – potentially initiating ERA–PDE-5 inhibitor combination therapy – but still should collaborate with PH experts.

“It’s a good idea to comanage these patients and let the experts see them periodically to help you determine when your patient may be declining,” he said. “The timetable for reassessment, the complexity of the reassessment, and the need to escalate to more advanced therapies has never been more important.”
 

Research highlights

Therapies that target inflammation and altered metabolism – including metformin – are among those being investigated for PAH. So are therapies targeting dysfunctional bone morphogenetic protein pathway signaling, which has been shown to be associated with hereditary, idiopathic, and likely other forms of PAH; one such drug, called sotatercept, is currently at the phase 3 trial stage.

Most promising for PAH may be the research efforts involving deep phenotyping, said Andrew J. Sweatt, MD, of Stanford (Calif.) University and the Vera Moulton Wall Center for Pulmonary Vascular Disease.

“It’s where a lot of research is headed – deep phenotyping to deconstruct the molecular and clinical heterogeneity that exists within PAH ... to detect distinct subphenotypes of patients who would respond to particular therapies,” said Dr. Sweatt, who led a review of PH clinical research presented at the 2020 American Thoracic Society International Conference

“Right now, we largely treat all patients the same ... [while] we know that patients have a wide response to therapies and there’s a lot of clinical heterogeneity in how their disease evolves over time,” he said.

Data from a large National Institutes of Health–funded multicenter phenotyping study of PH is being analyzed and should yield findings and publications starting this year, said Anna R. Hemnes, MD, associate professor of medicine at Vanderbilt University Medical Center, Nashville, Tenn., and an investigator with the initiative, coined “Redefining Pulmonary Hypertension through Pulmonary Disease Phenomics (PVDOMICS).”

Patients have undergone advanced imaging (for example, echocardiography, cardiac MRI, chest CT, ventilation/perfusion scans), advanced testing through right heart catheterization, body composition testing, quality of life questionnaires, and blood draws that have been analyzed for DNA and RNA expression, proteomics, and metabolomics, said Dr. Hemnes, assistant director of Vanderbilt’s Pulmonary Vascular Center.

The initiative aims to refine the classification of all kinds of PH and “to bring precision medicine to the field so we’re no longer characterizing somebody [based on imaging] and right heart catheterization, but we also incorporating molecular pieces and biomarkers into the diagnostic evaluation,” she said.

In the short term, the results of deep phenotyping should “allow us to be more effective with our therapy recommendations,” Dr. Hemnes said. “Then hopefully in the longer term, [identified biomarkers] will help us to develop new, more effective therapies.”

Dr. Sweatt and Dr. Williamson reported that they have no relevant financial disclosures. Dr. Hemnes reported that she holds stock in Tenax (which is studying a tyrosine kinase inhibitor for PAH) and serves as a consultant for Acceleron, Bayer, GossamerBio, United Therapeutics, and Janssen. She also receives research funding from Imara. Dr. Chakinala reported that he is an investigator on clinical trials for a number of pharmaceutical companies. He also serves on advisory boards for Phase Bio, Liquidia/Rare Gen, Bayer, Janssen, Trio Health Analytics, and Aerovate.

PAH specifically is defined as the presence of mPAP of at least 20 mm Hg, PVR of at least 3 Wood units, and pulmonary arterial wedge pressure 15 mm Hg or less.
 

Trends in treatment

The value of initial combination therapy with an endothelin receptor antagonist (ERA) and a phosphodiesterase-5 (PDE5) inhibitor in treatment-naive PAH was cemented in 2015 by the AMBITION trial. The primary endpoint (death, PAH hospitalization, or unsatisfactory clinical response) occurred in 18%, 34%, and 28% of patients who were randomized, respectively, to combination therapy, monotherapy with the ERA ambrisentan, or monotherapy with the PDE-5 inhibitor tadalafil – and in 31% of the two monotherapy groups combined.

The trial reported a 50% reduction in the primary endpoint in the combination-therapy group versus the pooled monotherapy group, as well as greater reductions in N-terminal of the prohormone brain natriuretic peptide levels, more satisfactory clinical response and greater improvement in 6-minute walking distance.

In practice, a minority of patients – typically older patients with multiple comorbidities – still receive initial monotherapy with sequential add-on therapies based on tolerance, but “for the most part PAH patients will start on combination therapy, most commonly with a ERA and PDE5 inhibitor,” Dr. Chakinala said.

For patients who are not improving on the ERA-PDE5 inhibitor approach – typically those who remain in the intermediate-risk category for intermediate-term mortality – substitution of the PDE5 inhibitor with the soluble guanylate cyclase stimulator riociguat may be considered, he and Dr. Williamson said. Clinical improvement with this substitution was demonstrated in the REPLACE trial.

Experts at PH care centers are also utilizing triple therapy for patients who do not improve to low-risk status after 2-4 months of dual combination therapy. The availability of oral prostacyclin analogues (selexipag and treprostinil) makes it easier to consider adding these agents early on, Dr. Chakinala and Dr. Richardson said.

Patients who fall into the high-risk category, at any point, are still best managed with parenteral prostacyclin analogues, Dr. Chakinala said.

In general, said Dr. Williamson, who also directs the University of Kansas Pulmonary Hypertension Comprehensive Care Center, “the PH community tends to be fairly aggressive up front, and with a low threshold for using prostacyclin analogues.”

The agents are “always part of the picture for someone who is really ill, in functional class IV, or has really impaired right ventricular function,” he said. “And we’re finding increased roles in patients who are not as ill but still have decompensated right ventricular dysfunction. It’s something we now consider.”

Recently published research on up-front oral triple therapy suggests possible benefit for some patients – but it’s far from conclusive, said Dr. Chakinala. The TRITON study randomized treatment-naive patients to the traditional ERA-PDE5 combination and either oral selexipag (a selective prostacyclin receptor agonist) or placebo as a third agent. It found no significant difference in reduction in PVR, the primary outcome, at week 26. However, the authors reported a “possible signal” for improved long-term outcomes with triple therapy.

“Based on this best evidence from a randomized clinical trial, I think it’s unfair to say that all patients should be on triple combination therapy right out of the gate,” he said. “Having said that, more recent [European] data showed that two drugs fell short of the mark in some patients, with high rates of clinical progression. And even in AMBITION, there were a number of patients in the combination arm who didn’t have a robust response.”

A 2021 retrospective analysis from the French Pulmonary Hypertension Registry – one of the European studies – assessed survival with monotherapy, dual therapy, or triple-combination therapy (two orals with a parenteral prostacyclin), and found no difference between monotherapy and dual therapy in high-risk patients.

Experts have been upping the ante, therefore, on early assessment and frequent reassessment of treatment response. Not long ago, patients were typically reassessed 6-12 months after the initiation of treatment. Now, experts at the PH care centers want to assess patients at 3-4 months and adjust or intensify treatment regimens for those who don’t yet qualify as low risk using a multidimensional risk score calculator.

The REVEAL (Registry to Evaluate Early and Long-Term PAH Management) risk score calculator, for instance, predicts the probability of 1-year survival and assigns patients to a strata of risk level based on either 12 or 6 variables (for the full or “lite” versions).]

Even better monitoring and risk assessment is needed, however, to “help sift out which patients are not improving enough on initial therapy or who are starting to fall off after being on a regimen for a period of time,” Dr. Chakinala said.

Today, with a network of accredited centers of expertise and a desire and need for many patients to remain close to home, Dr. Chakinala encourages finding a balance. Well-resourced clinicians can strive for early diagnosis and management – potentially initiating ERA–PDE-5 inhibitor combination therapy – but still should collaborate with PH experts.

“It’s a good idea to comanage these patients and let the experts see them periodically to help you determine when your patient may be declining,” he said. “The timetable for reassessment, the complexity of the reassessment, and the need to escalate to more advanced therapies has never been more important.”
 

Research highlights

Therapies that target inflammation and altered metabolism – including metformin – are among those being investigated for PAH. So are therapies targeting dysfunctional bone morphogenetic protein pathway signaling, which has been shown to be associated with hereditary, idiopathic, and likely other forms of PAH; one such drug, called sotatercept, is currently at the phase 3 trial stage.

Most promising for PAH may be the research efforts involving deep phenotyping, said Andrew J. Sweatt, MD, of Stanford (Calif.) University and the Vera Moulton Wall Center for Pulmonary Vascular Disease.

“It’s where a lot of research is headed – deep phenotyping to deconstruct the molecular and clinical heterogeneity that exists within PAH ... to detect distinct subphenotypes of patients who would respond to particular therapies,” said Dr. Sweatt, who led a review of PH clinical research presented at the 2020 American Thoracic Society International Conference

“Right now, we largely treat all patients the same ... [while] we know that patients have a wide response to therapies and there’s a lot of clinical heterogeneity in how their disease evolves over time,” he said.

Data from a large National Institutes of Health–funded multicenter phenotyping study of PH is being analyzed and should yield findings and publications starting this year, said Anna R. Hemnes, MD, associate professor of medicine at Vanderbilt University Medical Center, Nashville, Tenn., and an investigator with the initiative, coined “Redefining Pulmonary Hypertension through Pulmonary Disease Phenomics (PVDOMICS).”

Patients have undergone advanced imaging (for example, echocardiography, cardiac MRI, chest CT, ventilation/perfusion scans), advanced testing through right heart catheterization, body composition testing, quality of life questionnaires, and blood draws that have been analyzed for DNA and RNA expression, proteomics, and metabolomics, said Dr. Hemnes, assistant director of Vanderbilt’s Pulmonary Vascular Center.

The initiative aims to refine the classification of all kinds of PH and “to bring precision medicine to the field so we’re no longer characterizing somebody [based on imaging] and right heart catheterization, but we also incorporating molecular pieces and biomarkers into the diagnostic evaluation,” she said.

In the short term, the results of deep phenotyping should “allow us to be more effective with our therapy recommendations,” Dr. Hemnes said. “Then hopefully in the longer term, [identified biomarkers] will help us to develop new, more effective therapies.”

Dr. Sweatt and Dr. Williamson reported that they have no relevant financial disclosures. Dr. Hemnes reported that she holds stock in Tenax (which is studying a tyrosine kinase inhibitor for PAH) and serves as a consultant for Acceleron, Bayer, GossamerBio, United Therapeutics, and Janssen. She also receives research funding from Imara. Dr. Chakinala reported that he is an investigator on clinical trials for a number of pharmaceutical companies. He also serves on advisory boards for Phase Bio, Liquidia/Rare Gen, Bayer, Janssen, Trio Health Analytics, and Aerovate.

Aggressive up-front combination therapy, more lofty treatment goals, and earlier and more frequent reassessments to guide treatment are improving care of patients with pulmonary arterial hypertension (PAH) while at the same time making it more complex.

A larger number of oral and generic treatment options have in some respects ushered in more management ease. But overall, “I don’t know if management of these patients has ever been more complicated, given the treatment options and strategies,” said Murali M. Chakinala, MD, professor of medicine at Washington University, St. Louis. “We’re always thinking through approaches.”

Diagnosis continues to be challenging given the rarity of PAH and its nonspecific presentation – and in some cases it’s now harder. Experts such as Dr. Chakinala are seeing increasing number of aging patients with left heart disease, chronic kidney disease, and other comorbidities who have significant precapillary pulmonary hypertension and who exhibit hemodynamics consistent with PAH, or group 1 PH.

The question experts face is, do such patients have “true PAH,” as do a reported 25-50 people per million, or do they have another type of PH in the classification schema – or a mixture?

Deciding which patients “really fit into group 1 and should be managed like group 1,” Dr. Chakinala said, requires clinical acumen and has important implications, as patients with PAH are the main beneficiaries of vasodilator therapy. Most other patients with PH will not respond to or tolerate such treatment.

“These older patients may be getting PAH through different mechanisms than our younger patients, but because we define PAH through hemodynamic criteria and by ruling out other obvious explanations, they all get lumped together,” said Dr. Chakinala. “We need to parse these patients out better in the future, much like our oncology colleagues are doing.”

Personalized medicine hopefully is the next horizon for this condition, characterized by severe remodeling of the distal pulmonary arteries. Researchers are pushing to achieve deep phenotyping, identify biomarkers and improve risk assessment tools.

And with 80 or so centers now accredited by the Pulmonary Hypertension Association as Pulmonary Hypertension Care Centers, referred patients are accessing clinical trials of new nonvasodilatory drugs. Currently available therapies improve hemodynamics and symptoms, and can slow disease progression, but are not truly disease modifying, sources say.

“The endothelin, nitric oxide, and prostacyclin pathways have been exhaustively studied and we now have great drugs for those pathways,” said Dr. Chakinala, who leads the PHA’s scientific leadership council. But “we’re not going to put a greater dent into this disease until we have new drugs that work on different biologic pathways.”
 

Diagnostic challenges

The diagnosis of PAH – a remarkably heterogeneous condition that encompasses heritable forms and idiopathic forms, and that comprises a broad mix of predisposing conditions and exposures, from scleroderma to methamphetamine use – is still too often missed or delayed. Delayed diagnoses and misdiagnoses of PAH and other types of PH have been reported in up to 85% of at-risk patients, according to a 2016 literature review.

Being able to pivot from thinking about common pulmonary ailments or heart failure to considering PAH is a key part of earlier diagnosis and better treatment outcomes. “If someone has unexplained dyspnea or if they’re treated for other lung diseases and are not improving, think about a screening echocardiogram,” said Timothy L. Williamson, MD, vice president of quality and safety and a pulmonary and critical care physician at the University of Kansas Health Center, Kansas City.

One of the most common reasons Dr. Chakinala sees for missed diagnoses are right heart catheterizations that are incomplete or misinterpreted. (Right heart catheterizations are required to confirm the diagnosis.) “One can’t simply measure pressures and stop,” he said. “We need the full hemodynamic profile to know that it’s truly precapillary PAH ... and we need proper interpretation of [elements like] the waveforms.”

The 2019 World Symposium on Pulmonary Hypertension shifted the definition of PH from an arbitrarily defined mean pulmonary arterial pressure of at least 25 mm Hg at rest (as measured by right heart catheterization) to a more scientifically determined mPAP of at least 20 mm Hg.

The classification document also requires pulmonary vascular resistance (PVR) of at least 3 Wood units in the definition of all forms of precapillary PH.

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.

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.

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.

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.

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.

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.

Right now, more than 106,600 people in the United States are on the national transplant waiting list, each hoping to hear soon that a lung, kidney, heart, or other vital organ has been found for them. It’s the promise not just of a new organ, but a new life.

Well before they are placed on that list, transplant candidates, as they’re known, are evaluated with a battery of tests and exams to be sure they are infection free, their other organs are healthy, and that all their vaccinations are up to date.

Now, COVID vaccinations – and some people’s resistance to them – have turned what used to be routine preparation controversial.

In January, a 31-year-old Boston father of two declined to get the COVID-19 vaccine, and Brigham and Women’s Hospital officials removed him from the heart transplant waiting list. And in North Carolina, a 38-year-old man in need of a kidney transplant said he, too, was denied the organ when he declined to get the vaccination.

Those are just two of the most recent cases. The decisions by the transplant centers to remove the candidates from the waiting list have set off a national debate among ethicists, family members, doctors, patients, and others.

On social media and in conversation, the question persists: Is removing them from the list unfair and cruel, or simply business as usual to keep the patient as healthy as possible and the transplant as successful as possible?

Two recent tweets sum up the debate.

“The people responsible for this should be charged with attempted homicide,” one Twitter user said, while another suggested that the more accurate way to headline the news about a transplant candidate refusing the COVID-19 vaccine would be: “Patient voluntarily forfeits donor organ.”

Doctors and ethics experts, as well as other patients on the waiting list, say it’s simply good medicine to require the COVID vaccine, along with a host of other pretransplant requirements.
 

Transplant protocols

“Transplant medicine has always been a strong promoter of vaccination,” said Silas Prescod Norman, MD, a clinical associate professor of nephrology and internal medicine at the University of Michigan, Ann Arbor. He is a kidney specialist who works in the university’s transplant clinic.

Requiring the COVID vaccine is in line with requirements to get numerous other vaccines, he said.“Promoting the COVID vaccine among our transplant candidates and recipients is just an extension of our usual practice.

“In transplantation, first and foremost is patient safety,” Dr. Norman said. “And we know that solid organ transplant patients are at substantially higher risk of contracting COVID than nontransplant patients.”

After the transplant, they are placed on immunosuppressant drugs, that weaken the immune system while also decreasing the body’s ability to reject the new organ.

“We know now, because there is good data about the vaccine to show that people who are on transplant medications are less likely to make detectable antibodies after vaccination,” said Dr. Norman, who’s also a medical adviser for the American Kidney Fund, a nonprofit that provides kidney health information and financial assistance for dialysis.

And this is not a surprise because of the immunosuppressive effects, he said. “So it only makes sense to get people vaccinated before transplantation.”

Researchers compared the cases of more than 17,000 people who had received organ transplants and were hospitalized from April to November 2020, either for COVID (1,682 of them) or other health issues. Those who had COVID were more likely to have complications and to die in the hospital than those who did not have it.
 

Vaccination guidelines, policies

Federal COVID-19 treatment guidelines from the National Institutes of Health state that transplant patients on immunosuppressant drugs used after the procedure should be considered at a higher risk of getting severe COVID if infected.

In a joint statement from the American Society of Transplant Surgeons, the American Society of Transplantation, and the International Society for Heart and Lung Transplantation, the organizations say they “strongly recommend that all eligible children and adult transplant candidates and recipients be vaccinated with a COVID-19 vaccine [and booster] that is approved or authorized in their jurisdiction. Whenever possible, vaccination should occur prior to transplantation.” Ideally, it should be completed at least 2 weeks before the transplant.

The organizations also “support the development of institutional policies regarding pretransplant vaccination. We believe that this is in the best interest of the transplant candidate, optimizing their chances of getting through the perioperative and posttransplant periods without severe COVID-19 disease, especially at times of greater infection prevalence.”

Officials at Brigham and Women’s Hospital, where the 31-year-old father was removed from the list, issued a statement that reads, in part: “Our Mass General Brigham health care system requires several [Centers for Disease Control and Prevention]-recommended vaccines, including the COVID-19 vaccine, and lifestyle behaviors for transplant candidates to create both the best chance for a successful operation and to optimize the patient’s survival after transplantation, given that their immune system is drastically suppressed. Patients are not active on the wait list without this.”
 

Ethics amid organ shortage

“Organs are scarce,” said Arthur L. Caplan, PhD, director of the division of medical ethics at New York University Langone Medical Center. That makes the goal of choosing the very best candidates for success even more crucial.

“You try to maximize the chance the organ will work,” he said. Pretransplant vaccination is one way.

The shortage is most severe for kidney transplants. In 2020, according to federal statistics, more than 91,000 kidney transplants were needed, but fewer than 23,000 were received. During 2021, 41,354 transplants were done, an increase of nearly 6% over the previous year. The total includes kidneys, hearts, lungs, and other organs, with kidneys accounting for more than 24,000 of the total.

Even with the rise in transplant numbers, supply does not meet demand. According to federal statistics, 17 people in the United States die each day waiting for an organ transplant. Every 9 minutes, someone is added to the waiting list.

“This isn’t and it shouldn’t be a fight about the COVID vaccine,” Dr. Caplan said. “This isn’t an issue about punishing non-COVID vaccinators. It’s deciding who is going to get a scarce organ.”

“A lot of people [opposed to removing the nonvaccinated from the list] think: ‘Oh, they are just killing those people who won’t take a COVID vaccine.’ That’s not what is going on.”

The transplant candidate must be in the best possible shape overall, Dr. Caplan and doctors agreed. Someone who is smoking, drinking heavily, or abusing drugs isn’t going to the top of the list either. And for other procedures, such as bariatric surgery or knee surgery, some patients are told first to lose weight before a surgeon will operate.

The worry about side effects from the vaccine, which some patients have cited as a concern, is misplaced, Dr. Caplan said. What transplant candidates who refuse the COVID vaccine may not be thinking about is that they are facing a serious operation and will be on numerous anti-rejection drugs, with side effects, after the surgery.

“So to be worried about the side effects of a COVID vaccine is irrational,” he said.
 

Transplants: The process

The patients who were recently removed from the transplant list could seek care and a transplant at an alternate center, said Anne Paschke, a spokesperson for the United Network for Organ Sharing, a nonprofit group that is under contract with the federal government and operates the national Organ Procurement and Transplantation Network (OPTN).

“Transplant hospitals decide which patients to add to the wait list based on their own criteria and medical judgment to create the best chance for a positive transplant outcome,” she said. That’s done with the understanding that patients will help with their medical care.

So, if one program won’t accept a patient, another may. But, if a patient turned down at one center due to refusing to get the COVID vaccine tries another center, the requirements at that hospital may be the same, she said.

OPTN maintains a list of transplant centers. As of Jan. 28, there were 251 transplant centers, according to UNOS, which manages the waiting list, matches donors and recipients, and strives for equity, among other duties.
 

Pretransplant refusers not typical

“The cases we are seeing are outliers,” Dr. Caplan said of the handful of known candidates who have refused the vaccine. Most ask their doctor exactly what they need to do to live and follow those instructions.

Dr. Norman agreed. Most of the kidney patients he cares for who are hoping for a transplant have been on dialysis, “which they do not like. They are doing whatever they can to make sure they don’t go back on dialysis. As a group, they tend to be very adherent, very safety conscious because they understand their risk and they understand the gift they have received [or will receive] through transplantation. They want to do everything they can to respect and protect that gift.”

Not surprisingly, some on the transplant list who are vaccinated have strong opinions about those who refuse to get the vaccine. Dana J. Ufkes, 61, a Seattle realtor, has been on the kidney transplant list – this time – since 2003, hoping for her third transplant. When asked if potential recipients should be removed from the list if they refuse the COVID vaccine, her answer was immediate: “Absolutely.”

At age 17, Ms. Ufkes got a serious kidney infection that went undiagnosed and untreated. Her kidney health worsened, and she needed a transplant. She got her first one in 1986, then again in 1992.

“They last longer than they used to,” she said. But not forever. (According to the American Kidney Fund, transplants from a living kidney donor last about 15-20 years; from a deceased donor, 10-15.)

The decision to decline the vaccine is, of course, each person’s choice, Ms. Ufkes said. But “if they don’t want to be vaccinated [and still want to be on the list], I think that’s BS.”

Citing the lack of organs, “it’s not like they are handing these out like jellybeans.”

The organizations also “support the development of institutional policies regarding pretransplant vaccination. We believe that this is in the best interest of the transplant candidate, optimizing their chances of getting through the perioperative and posttransplant periods without severe COVID-19 disease, especially at times of greater infection prevalence.”

Officials at Brigham and Women’s Hospital, where the 31-year-old father was removed from the list, issued a statement that reads, in part: “Our Mass General Brigham health care system requires several [Centers for Disease Control and Prevention]-recommended vaccines, including the COVID-19 vaccine, and lifestyle behaviors for transplant candidates to create both the best chance for a successful operation and to optimize the patient’s survival after transplantation, given that their immune system is drastically suppressed. Patients are not active on the wait list without this.”
 

Ethics amid organ shortage

“Organs are scarce,” said Arthur L. Caplan, PhD, director of the division of medical ethics at New York University Langone Medical Center. That makes the goal of choosing the very best candidates for success even more crucial.

“You try to maximize the chance the organ will work,” he said. Pretransplant vaccination is one way.

The shortage is most severe for kidney transplants. In 2020, according to federal statistics, more than 91,000 kidney transplants were needed, but fewer than 23,000 were received. During 2021, 41,354 transplants were done, an increase of nearly 6% over the previous year. The total includes kidneys, hearts, lungs, and other organs, with kidneys accounting for more than 24,000 of the total.

Even with the rise in transplant numbers, supply does not meet demand. According to federal statistics, 17 people in the United States die each day waiting for an organ transplant. Every 9 minutes, someone is added to the waiting list.

“This isn’t and it shouldn’t be a fight about the COVID vaccine,” Dr. Caplan said. “This isn’t an issue about punishing non-COVID vaccinators. It’s deciding who is going to get a scarce organ.”

“A lot of people [opposed to removing the nonvaccinated from the list] think: ‘Oh, they are just killing those people who won’t take a COVID vaccine.’ That’s not what is going on.”

The transplant candidate must be in the best possible shape overall, Dr. Caplan and doctors agreed. Someone who is smoking, drinking heavily, or abusing drugs isn’t going to the top of the list either. And for other procedures, such as bariatric surgery or knee surgery, some patients are told first to lose weight before a surgeon will operate.

The worry about side effects from the vaccine, which some patients have cited as a concern, is misplaced, Dr. Caplan said. What transplant candidates who refuse the COVID vaccine may not be thinking about is that they are facing a serious operation and will be on numerous anti-rejection drugs, with side effects, after the surgery.

“So to be worried about the side effects of a COVID vaccine is irrational,” he said.
 

Transplants: The process

The patients who were recently removed from the transplant list could seek care and a transplant at an alternate center, said Anne Paschke, a spokesperson for the United Network for Organ Sharing, a nonprofit group that is under contract with the federal government and operates the national Organ Procurement and Transplantation Network (OPTN).

“Transplant hospitals decide which patients to add to the wait list based on their own criteria and medical judgment to create the best chance for a positive transplant outcome,” she said. That’s done with the understanding that patients will help with their medical care.

So, if one program won’t accept a patient, another may. But, if a patient turned down at one center due to refusing to get the COVID vaccine tries another center, the requirements at that hospital may be the same, she said.

OPTN maintains a list of transplant centers. As of Jan. 28, there were 251 transplant centers, according to UNOS, which manages the waiting list, matches donors and recipients, and strives for equity, among other duties.
 

Pretransplant refusers not typical

“The cases we are seeing are outliers,” Dr. Caplan said of the handful of known candidates who have refused the vaccine. Most ask their doctor exactly what they need to do to live and follow those instructions.

Dr. Norman agreed. Most of the kidney patients he cares for who are hoping for a transplant have been on dialysis, “which they do not like. They are doing whatever they can to make sure they don’t go back on dialysis. As a group, they tend to be very adherent, very safety conscious because they understand their risk and they understand the gift they have received [or will receive] through transplantation. They want to do everything they can to respect and protect that gift.”

Not surprisingly, some on the transplant list who are vaccinated have strong opinions about those who refuse to get the vaccine. Dana J. Ufkes, 61, a Seattle realtor, has been on the kidney transplant list – this time – since 2003, hoping for her third transplant. When asked if potential recipients should be removed from the list if they refuse the COVID vaccine, her answer was immediate: “Absolutely.”

At age 17, Ms. Ufkes got a serious kidney infection that went undiagnosed and untreated. Her kidney health worsened, and she needed a transplant. She got her first one in 1986, then again in 1992.

“They last longer than they used to,” she said. But not forever. (According to the American Kidney Fund, transplants from a living kidney donor last about 15-20 years; from a deceased donor, 10-15.)

The decision to decline the vaccine is, of course, each person’s choice, Ms. Ufkes said. But “if they don’t want to be vaccinated [and still want to be on the list], I think that’s BS.”

Citing the lack of organs, “it’s not like they are handing these out like jellybeans.”

Right now, more than 106,600 people in the United States are on the national transplant waiting list, each hoping to hear soon that a lung, kidney, heart, or other vital organ has been found for them. It’s the promise not just of a new organ, but a new life.

Well before they are placed on that list, transplant candidates, as they’re known, are evaluated with a battery of tests and exams to be sure they are infection free, their other organs are healthy, and that all their vaccinations are up to date.

Now, COVID vaccinations – and some people’s resistance to them – have turned what used to be routine preparation controversial.

In January, a 31-year-old Boston father of two declined to get the COVID-19 vaccine, and Brigham and Women’s Hospital officials removed him from the heart transplant waiting list. And in North Carolina, a 38-year-old man in need of a kidney transplant said he, too, was denied the organ when he declined to get the vaccination.

Those are just two of the most recent cases. The decisions by the transplant centers to remove the candidates from the waiting list have set off a national debate among ethicists, family members, doctors, patients, and others.

On social media and in conversation, the question persists: Is removing them from the list unfair and cruel, or simply business as usual to keep the patient as healthy as possible and the transplant as successful as possible?

Two recent tweets sum up the debate.

“The people responsible for this should be charged with attempted homicide,” one Twitter user said, while another suggested that the more accurate way to headline the news about a transplant candidate refusing the COVID-19 vaccine would be: “Patient voluntarily forfeits donor organ.”

Doctors and ethics experts, as well as other patients on the waiting list, say it’s simply good medicine to require the COVID vaccine, along with a host of other pretransplant requirements.
 

Transplant protocols

“Transplant medicine has always been a strong promoter of vaccination,” said Silas Prescod Norman, MD, a clinical associate professor of nephrology and internal medicine at the University of Michigan, Ann Arbor. He is a kidney specialist who works in the university’s transplant clinic.

Requiring the COVID vaccine is in line with requirements to get numerous other vaccines, he said.“Promoting the COVID vaccine among our transplant candidates and recipients is just an extension of our usual practice.

“In transplantation, first and foremost is patient safety,” Dr. Norman said. “And we know that solid organ transplant patients are at substantially higher risk of contracting COVID than nontransplant patients.”

After the transplant, they are placed on immunosuppressant drugs, that weaken the immune system while also decreasing the body’s ability to reject the new organ.

“We know now, because there is good data about the vaccine to show that people who are on transplant medications are less likely to make detectable antibodies after vaccination,” said Dr. Norman, who’s also a medical adviser for the American Kidney Fund, a nonprofit that provides kidney health information and financial assistance for dialysis.

And this is not a surprise because of the immunosuppressive effects, he said. “So it only makes sense to get people vaccinated before transplantation.”

Researchers compared the cases of more than 17,000 people who had received organ transplants and were hospitalized from April to November 2020, either for COVID (1,682 of them) or other health issues. Those who had COVID were more likely to have complications and to die in the hospital than those who did not have it.
 

Vaccination guidelines, policies

Federal COVID-19 treatment guidelines from the National Institutes of Health state that transplant patients on immunosuppressant drugs used after the procedure should be considered at a higher risk of getting severe COVID if infected.

In a joint statement from the American Society of Transplant Surgeons, the American Society of Transplantation, and the International Society for Heart and Lung Transplantation, the organizations say they “strongly recommend that all eligible children and adult transplant candidates and recipients be vaccinated with a COVID-19 vaccine [and booster] that is approved or authorized in their jurisdiction. Whenever possible, vaccination should occur prior to transplantation.” Ideally, it should be completed at least 2 weeks before the transplant.
