FDA approves first-ever agent to delay type 1 diabetes onset
“Today’s approval of a first-in-class therapy adds an important new treatment option for certain at-risk patients,” said John Sharretts, MD, director of the Division of Diabetes, Lipid Disorders, and Obesity in the FDA’s Center for Drug Evaluation and Research. “The drug’s potential to delay clinical diagnosis of type 1 diabetes may provide patients with months to years without the burdens of disease.”
The agent, which interferes with T-cell-mediated autoimmune destruction of pancreatic beta cells, is the first disease-modifying therapy for impeding progression of type 1 diabetes. It is administered by intravenous infusion once daily for 14 consecutive days.
The specific indication is “to delay the onset of stage 3 type 1 diabetes in adults and pediatric patients 8 years and older who currently have stage 2 type 1 diabetes.” In type 1 diabetes staging, adopted in 2015, stage 1 is defined as the presence of beta cell autoimmunity with two or more islet autoantibodies with normoglycemia, stage 2 is beta-cell autoimmunity with dysglycemia yet asymptomatic, and stage 3 is the onset of symptomatic type 1 diabetes.
Stage 2 type 1 diabetes is associated with a nearly 100% lifetime risk of progression to clinical (stage 3) type 1 diabetes and a 75% risk of developing the condition within 5 years.
The FDA had previously rejected teplizumab for this indication in July 2021, despite a prior endorsement from an advisory panel in May 2021.
Now, with the FDA approval, Provention Bio cofounder and CEO Ashleigh Palmer said in a statement, “This is a historic occasion for the T1D community and a paradigm shifting breakthrough ... It cannot be emphasized enough how precious a delay in the onset of stage 3 T1D can be from a patient and family perspective; more time to live without and, when necessary, prepare for the burdens, complications, and risks associated with stage 3 disease.”
T1D onset delayed by 2 years
In 2019, a pivotal phase 2, randomized, placebo-controlled trial involving 76 at-risk children and adults aged 8 years and older showed that a single 14-day treatment of daily intravenous infusions of teplizumab in 44 patients resulted in a significant median 2-year delay to onset of clinical type 1 diabetes compared with 32 who received placebo.
Those “game changer” data were presented at the American Diabetes Association (ADA) annual meeting in June 2019 and simultaneously published in the New England Journal of Medicine.
Three-year data were presented at the June 2020 ADA meeting and published in March 2021 in Science Translational Medicine, by Emily K. Sims, MD, department of pediatrics, Indiana University, Indianapolis, and colleagues.
At a median follow-up of 923 days, 50% of those randomly assigned to teplizumab remained diabetes free, compared with 22% of those who received placebo infusions (hazard ratio, 0.457; P = .01). The teplizumab group had a greater average C-peptide area under the curve compared with placebo, reflecting improved beta-cell function (1.96 vs. 1.68 pmol/mL; P = .006).
C-peptide levels declined over time in the placebo group but stabilized in those receiving teplizumab (P = .0015).
“The mid-range time from randomization to stage 3 type 1 diabetes diagnosis was 50 months for the patients who received Tzield and 25 months for those who received a placebo. This represents a statistically significant delay in the development of stage 3 type 1 diabetes,” according to the FDA statement.
The most common side effects of Tzield include lymphopenia (73% teplizumab vs. 6% placebo), rash (36% vs. 0%), leukopenia (221% vs. 0%), and headache (11% vs. 6%). Label warnings and precautions include monitoring for cytokine release syndrome, risk for serious infections, and avoidance of live, inactivated, and mRNA vaccines.
This approval is likely to accelerate discussion about universal autoantibody screening. Currently, most individuals identified as having preclinical type 1 diabetes are first-degree relatives of people with type 1 diabetes identified through the federally funded TrialNet program. In December 2020, the type 1 diabetes research and advocacy organization JDRF began offering a $55 home blood test to screen for the antibodies, and other screening programs have been launched in the United States and Europe.
Previous studies have examined cost-effectiveness of universal screening in children and the optimal ages that such screening should take place.
In October, Provention Bio announced a co-promotion agreement with Sanofi for the U.S. launch of Tzield for delay in onset of clinical T1D in at-risk individuals. Provention Bio offers financial assistance options (e.g., copay assistance) to eligible patients for out-of-pocket costs.

A plane crash interrupts a doctor’s vacation
Emergencies happen anywhere, anytime – and sometimes physicians find themselves in situations where they are the only ones who can help. “Is There a Doctor in the House?” is a new series telling these stories.
When the plane crashed, I was asleep. I had arrived the evening before with my wife and three sons at a house on Kezar Lake on the Maine–New Hampshire border. I jumped out of bed and ran downstairs. My kids had been watching a float plane circling and gliding along the lake. It had crashed into the water and flipped upside down. My oldest brother-in-law jumped into his ski boat and we sped out to the scene.
All we can see are the plane’s pontoons. The rest is underwater. A woman has already surfaced, screaming. I dive in.
I find the woman’s husband and 3-year-old son struggling to get free from the plane through the smashed windshield. They manage to get to the surface. The pilot is dead, impaled through the chest by the left wing strut.
The big problem: A little girl, whom I would learn later is named Lauren, remained trapped. The water is murky but I can see her, a 5- or 6-year-old girl with this long hair, strapped in upside down and unconscious.
The mom and I dive down over and over, pulling and ripping at the door. We cannot get it open. Finally, I’m able to bend the door open enough where I can reach in, but I can’t undo the seatbelt. In my mind, I’m debating, should I try and go through the front windshield? I’m getting really tired, I can tell there’s fuel in the water, and I don’t want to drown in the plane. So I pop up to the surface and yell, “Does anyone have a knife?”
My brother-in-law shoots back to shore in the boat, screaming, “Get a knife!” My niece gets in the boat with one. I’m standing on the pontoon, and my niece is in the front of the boat calling, “Uncle Todd! Uncle Todd!” and she throws the knife. It goes way over my head. I can’t even jump for it, it’s so high.
I have to get the knife. So, I dive into the water to try and find it. Somehow, the black knife has landed on the white wing, 4 or 5 feet under the water. Pure luck. It could have sunk down a hundred feet into the lake. I grab the knife and hand it to the mom, Beth. She’s able to cut the seatbelt, and we both pull Lauren to the surface.
I lay her out on the pontoon. She has no pulse and her pupils are fixed and dilated. Her mom is yelling, “She’s dead, isn’t she?” I start CPR. My skin and eyes are burning from the airplane fuel in the water. I get her breathing, and her heart comes back very quickly. Lauren starts to vomit and I’m trying to keep her airway clear. She’s breathing spontaneously and she has a pulse, so I decide it’s time to move her to shore.
We pull the boat up to the dock and Lauren’s now having anoxic seizures. Her brain has been without oxygen, and now she’s getting perfused again. We get her to shore and lay her on the lawn. I’m still doing mouth-to-mouth, but she’s seizing like crazy, and I don’t have any way to control that. Beth is crying and wants to hold her daughter gently while I’m working.
Someone had called 911, and finally this dude shows up with an ambulance, and it’s like something out of World War II. All he has is an oxygen tank, but the mask is old and cracked. It’s too big for Lauren, but it sort of fits me, so I’m sucking in oxygen and blowing it into the girl’s mouth. I’m doing whatever I can, but I don’t have an IV to start. I have no fluids. I got nothing.
As it happens, I’d done my emergency medicine training at Maine Medical Center, so I tell someone to call them and get a Life Flight chopper. We have to drive somewhere where the chopper can land, so we take the ambulance to the parking lot of the closest store called the Wicked Good Store. That’s a common thing in Maine. Everything is “wicked good.”
The whole town is there by that point. The chopper arrives. The ambulance doors pop open and a woman says, “Todd?” And I say, “Heather?”
Heather is an emergency flight nurse whom I’d trained with many years ago. There’s immediate trust. She has all the right equipment. We put in breathing tubes and IVs. We stop Lauren from seizing. The kid is soon stable.
There is only one extra seat in the chopper, so I tell Beth to go. They take off.
Suddenly, I begin to doubt my decision. Lauren had been underwater for 15 minutes at minimum. I know how long that is. Did I do the right thing? Did I resuscitate a brain-dead child? I didn’t think about it at the time, but if that patient had come to me in the emergency department, I’m honestly not sure what I would have done.
So, I go home. And I don’t get a call. The FAA and sheriff arrive to take statements from us. I don’t hear from anyone.
The next day I start calling. No one will tell me anything, so I finally get to one of the pediatric ICU attendings who had trained me. He says Lauren literally woke up and said, “I have to go pee.” And that was it. She was 100% normal. I couldn’t believe it.
Here’s a theory: In kids, there’s something called the glottic reflex. I think her glottic reflex went off as soon as she hit the water, which basically closed her airway. So when she passed out, she could never get enough water in her lungs and still had enough air in there to keep her alive. Later, I got a call from her uncle. He could barely get the words out because he was in tears. He said Lauren was doing beautifully.
Three days later, I drove to Lauren’s house with my wife and kids. I had her read to me. I watched her play on the jungle gym for motor function. All sorts of stuff. She was totally normal.
Beth told us that the night before the accident, her mother had given the women in her family what she called a “miracle bracelet,” a bracelet that is supposed to give you one miracle in your life. Beth said she had the bracelet on her wrist the day of the accident, and now it’s gone. “Saving Lauren’s life was my miracle,” she said.
Funny thing: For 20 years, I ran all the EMS, police, fire, ambulance, in Boulder, Colo., where I live. I wrote all the protocols, and I would never advise any of my paramedics to dive into jet fuel to save someone. That was risky. But at the time, it was totally automatic. I think it taught me not to give up in certain situations, because you really don’t know.

The next day I start calling. No one will tell me anything, so I finally get to one of the pediatric ICU attendings who had trained me. He says Lauren literally woke up and said, “I have to go pee.” And that was it. She was 100% normal. I couldn’t believe it.
Here’s a theory: In kids, there’s something called the glottic reflex. I think her glottic reflex went off as soon as she hit the water, which basically closed her airway. So when she passed out, she could never get enough water in her lungs and still had enough air in there to keep her alive. Later, I got a call from her uncle. He could barely get the words out because he was in tears. He said Lauren was doing beautifully.
Three days later, I drove to Lauren’s house with my wife and kids. I had her read to me. I watched her play on the jungle gym for motor function. All sorts of stuff. She was totally normal.
Beth told us that the night before the accident, her mother had given the women in her family what she called a “miracle bracelet,” a bracelet that is supposed to give you one miracle in your life. Beth said she had the bracelet on her wrist the day of the accident, and now it’s gone. “Saving Lauren’s life was my miracle,” she said.
Funny thing: For 20 years, I ran all the EMS, police, fire, ambulance, in Boulder, Colo., where I live. I wrote all the protocols, and I would never advise any of my paramedics to dive into jet fuel to save someone. That was risky. But at the time, it was totally automatic. I think it taught me not to give up in certain situations, because you really don’t know.

The tale of two scenarios of gender dysphoria
In a recent column, I cautiously discussed what has been called gender-affirming or transgender care.
In the days following the appearance of that Letters From Maine column on this topic, I received an unusual number of responses from readers suggesting I had touched on a topic that was on the minds of many pediatricians.
Since then, the Florida Board of Medicine and Osteopathic Medicine voted to forbid physicians from prescribing puberty blockers and hormones and/or performing surgeries in patients under age 18 who were seeking transgender care. Children already receiving treatments were exempt from the ruling. The osteopathic board added a second exception in cases where the child was a participant in a research protocol. The board of medicine inexplicably did not include this exception.
Regardless of how one feels about the ethics and the appropriateness of transgender care, it is not an issue to be decided by a politically appointed entity.
As I look back over what I have learned by watching this tragic drama play out, I am struck by a distinction that has yet to receive enough attention. When we are discussing gender dysphoria we are really talking about two different pediatric populations and scenarios. There is the child who from a very young age has consistently preferred to dress and behave in a manner that is different from the gender he or she was assigned at birth. The management of this child is a challenge that requires a careful balance of support and protection from the harsh realities of the gender-regimented world.
The second scenario stars the adolescent who has no prior history of gender dysphoria, or at least no outward manifestations. Then, faced by the challenges of puberty and adolescence, something or things happen that erupt into a full-blown gender-dysphoric storm. We currently have very little understanding of what those “things” are.
Each population can probably be further divided into subgroups – and that’s just the point. Every gender-dysphoric child, whether their dysphoria began at age 2 or 12, is an individual with a unique family dynamic and socioeconomic background. They may share some as yet unknown genetic signature, but in our current state of ignorance they deserve, as do all of our patients, to be treated as individuals by their primary care physicians and consultants who must at first do no harm. One size does not fit all and certainly their care should not be dictated by a politically influenced entity.
Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.

Give bacterial diversity a chance: The antibiotic dichotomy
What’s the opposite of an antibiotic?
Everyone knows that LOTME loves a good dichotomy: yin/yang, good/evil, heads/tails, particle/wave, peanut butter/jelly. They’re all great. We’re also big fans of microbiomes, particularly the gut microbiome. But what if we could combine the two? A healthy and nutritious story about the gut microbiome, with a dash of added dichotomy for flavor. Is such a thing even possible? Let’s find out.
First, we need an antibiotic, a drug designed to fight bacterial infections. If you’ve got strep throat, otitis media, or bubonic plague, there’s a good chance you will receive an antibiotic. That antibiotic will kill the bad bacteria that are making you sick, but it will also kill a lot of the good bacteria that inhabit your gut microbiome, which results in side effects like bloating and diarrhea.
It comes down to diversity, explained Elisa Marroquin, PhD, of Texas Christian University (Go Horned Frogs!): “In a human community, we need people that have different professions because we don’t all know how to do every single job. And so the same happens with bacteria. We need lots of different gut bacteria that know how to do different things.”
She and her colleagues reviewed 29 studies published over the last 7 years and found a way to preserve the diversity of a human gut microbiome that’s dealing with an antibiotic. Their solution? Prescribe a probiotic.
The way to fight the effects of stopping a bacterial infection is to provide food for what are, basically, other bacterial infections. Antibiotic/probiotic is a prescription for dichotomy, and it means we managed to combine gut microbiomes with a dichotomy. And you didn’t think we could do it.
The earphone of hearing aids
It’s estimated that up to 75% of people who need hearing aids don’t wear them. Why? Well, there’s the social stigma about not wanting to appear too old, and then there’s the cost factor.
Is there a cheaper, less stigmatizing option to amplify hearing? The answer, according to otolaryngologist Yen-fu Cheng, MD, of Taipei Veterans General Hospital and associates, is wireless earphones. AirPods, if you want to be brand specific.
Airpods can be on the more expensive side – running about $129 for AirPods 2 and $249 for AirPods Pro – but when compared with premium hearing aids ($10,000), or even basic aids (about $1,500), the Apple products come off inexpensive after all.
The team tested the premium and basic hearing aids against the AirPods 2 and the AirPod Pro using Apple’s Live Listen feature, which helps amplify sound through the company’s wireless earphones and iPhones and was initially designed to assist people with normal hearing in situations such as birdwatching.
The AirPods Pro worked just as well as the basic hearing aid but not quite as well as the premium hearing aid in a quiet setting, while the AirPods 2 performed the worst. When tested in a noisy setting, the AirPods Pro was pretty comparable to the premium hearing aid, as long as the noise came from a lateral direction. Neither of the AirPod models did as well as the hearing aids with head-on noises.
Wireless earbuds may not be the perfect solution from a clinical standpoint, but they’re a good start for people who don’t have access to hearing aids, Dr. Cheng noted.
So who says headphones damage your hearing? They might actually help.
Now I lay me down to sleep, I pray the computer my soul to keep
Radiation is the boring hazard of space travel. No one dies in a space horror movie because they’ve been slowly exposed to too much cosmic radiation. It’s always “thrown out the airlock” this and “eaten by a xenomorph” that.
Radiation, however, is not something that can be ignored, but it turns out that a potential solution is another science fiction staple: artificial hibernation. Generally in sci-fi, hibernation is a plot convenience to get people from point A to point B in a ship that doesn’t break the laws of physics. Here on Earth, though, it is well known that animals naturally entering a state of torpor during hibernation gain significant resistance to radiation.
The problem, of course, is that humans don’t hibernate, and no matter how hard people who work 100-hour weeks for Elon Musk try, sleeping for months on end is simply something we can’t do. However, a new study shows that it’s possible to induce this torpor state in animals that don’t naturally hibernate. By injecting rats with adenosine 5’-monophosphate monohydrate and keeping them in a room held at 16° C, an international team of scientists successfully induced a synthetic torpor state.
That’s not all they did: The scientists also exposed the hibernating rats to a large dose of radiation approximating that found in deep space. Which isn’t something we’d like to explain to our significant other when we got home from work. “So how was your day?” “Oh, I irradiated a bunch of sleeping rats. … Don’t worry they’re fine!” Which they were. Thanks to the hypoxic and hypothermic state, the tissue was spared damage from the high-energy ion radiation.
Obviously, there’s a big difference between a rat and a human and a lot of work to be done, but the study does show that artificial hibernation is possible. Perhaps one day we’ll be able to fall asleep and wake up light-years away under an alien sky, and we won’t be horrifically mutated or riddled with cancer. If, however, you find yourself in hibernation on your way to Jupiter (or Saturn) to investigate a mysterious black monolith, we suggest sleeping with one eye open and gripping your pillow tight.

‘A huge deal’: Millions have long COVID, and more are expected
with symptoms that have lasted 3 months or longer, according to the latest U.S. government survey done in October. More than a quarter say their condition is severe enough to significantly limit their day-to-day activities – yet the problem is only barely starting to get the attention of employers, the health care system, and policymakers.
With no cure or treatment in sight, long COVID is already burdening not only the health care system, but also the economy – and that burden is set to grow. Many experts worry about the possible long-term ripple effects, from increased spending on medical care costs to lost wages due to not being able to work, as well as the policy implications that come with addressing these issues.
“At this point, anyone who’s looking at this seriously would say this is a huge deal,” says senior Brookings Institution fellow Katie Bach, the author of a study that analyzed long COVID’s impact on the labor market.
“We need a real concerted focus on treating these people, which means both research and the clinical side, and figuring out how to build a labor market that is more inclusive of people with disabilities,” she said.
It’s not only that many people are affected. It’s that they are often affected for months and possibly even years.
The U.S. government figures suggest more than 18 million people could have symptoms of long COVID right now. The latest Household Pulse Survey by the Census Bureau and the National Center for Health Statistics takes data from 41,415 people.
A preprint of a study by researchers from City University of New York, posted on medRxiv in September and based on a similar population survey done between June 30 and July 2, drew comparable results. The study has not been peer reviewed.
More than 7% of all those who answered said they had long COVID at the time of the survey, which the researchers said corresponded to approximately 18.5 million U.S. adults. The same study found that a quarter of those, or an estimated 4.7 million adults, said their daily activities were impacted “a lot.”
This can translate into pain not only for the patients, but for governments and employers, too.
In high-income countries around the world, government surveys and other studies are shedding light on the extent to which post-COVID-19 symptoms – commonly known as long COVID – are affecting populations. While results vary, they generally fall within similar ranges.
The World Health Organization estimates that between 10% and 20% of those with COVID-19 go on to have an array of medium- to long-term post-COVID-19 symptoms that range from mild to debilitating. The U.S. Government Accountability Office puts that estimate at 10% to 30%; one of the latest studies published at the end of October in The Journal of the American Medical Association found that 15% of U.S. adults who had tested positive for COVID-19 reported current long COVID symptoms. Elsewhere, a study from the Netherlands published in The Lancet in August found that one in eight COVID-19 cases, or 12.7%, were likely to become long COVID.
“It’s very clear that the condition is devastating people’s lives and livelihoods,” WHO Director-General Tedros Adhanom Ghebreyesus wrote in an article for The Guardian newspaper in October.
“The world has already lost a significant number of the workforce to illness, death, fatigue, unplanned retirement due to an increase in long-term disability, which not only impacts the health system, but is a hit to the overarching economy … the impact of long COVID for all countries is very serious and needs immediate and sustained action equivalent to its scale.”
Global snapshot: Lasting symptoms, impact on activities
Patients describe a spectrum of persistent issues, with extreme fatigue, brain fog or cognitive problems, and shortness of breath among the most common complaints. Many also have manageable symptoms that worsen significantly after even mild physical or mental exertion.
Women appear almost twice as likely as men to get long COVID. Many patients have other medical conditions and disabilities that make them more vulnerable to the condition. Those who face greater obstacles accessing health care due to discrimination or socioeconomic inequity are at higher risk as well.
While many are older, a large number are also in their prime working age. The Census Bureau data show that people ages 40-49 are more likely than any other group to get long COVID, which has broader implications for labor markets and the global economy. Already, experts have estimated that long COVID is likely to cost the U.S. trillions of dollars and affect multiple industries.
“Whether they’re in the financial world, the medical system, lawyers, they’re telling me they’re sitting at the computer screen and they’re unable to process the data,” said Zachary Schwartz, MD, medical director for Vancouver General Hospital’s Post-COVID-19 Recovery Clinic.
“That is what’s most distressing for people, in that they’re not working, they’re not making money, and they don’t know when, or if, they’re going to get better.”
Nearly a third of respondents in the Census Bureau’s Household Pulse Survey who said they have had COVID-19 reported symptoms that lasted 3 months or longer. People between the ages of 30 and 59 were the most affected, with about 32% reporting symptoms. Across the entire adult U.S. population, the survey found that 1 in 7 adults have had long COVID at some point during the pandemic, with about 1 in 18 saying it limited their activity to some degree, and 1 in 50 saying they have faced “a lot” of limits on their activities. Any way these numbers are dissected, long COVID has impacted a large swath of the population.
Yet research into the causes and possible treatments of long COVID is just getting underway.
“The amount of energy and time devoted to it is way, way less than it should, given how many people are likely affected,” said David Cutler, PhD, professor of economics at Harvard University, Cambridge, Mass., who has written about the economic cost of long COVID. “We’re way, way underdoing it here. And I think that’s really a terrible thing.”
Population surveys and studies from around the world show that long COVID lives up to its name, with people reporting serious symptoms for months on end.
In October, Statistics Canada and the Public Health Agency of Canada published early results from a questionnaire done between spring and summer 2022 that found just under 15% of adults who had a confirmed or suspected case of COVID-19 went on to have new or continuing symptoms 3 or more months later. Nearly half, or 47.3%, dealt with symptoms that lasted a year or more. More than one in five said their symptoms “often or always” limited their day-to-day activities, which included routine tasks such as preparing meals, doing errands and chores, and basic functions such as personal care and moving around in their homes.
Nearly three-quarters of workers or students said they missed an average of 20 days of work or school.
“We haven’t yet been able to determine exactly when symptoms resolve,” said Rainu Kaushal, MD, the senior associate dean for clinical research at Weill Cornell Medicine in New York. She is co-leading a national study on long COVID in adults and children, funded by the National Institutes of Health RECOVER Initiative.
“But there does seem to be, for many of the milder symptoms, resolution at about 4-6 weeks. There seems to be a second point of resolution around 6 months for certain symptoms, and then some symptoms do seem to be permanent, and those tend to be patients who have underlying conditions,” she said.
Reducing the risk
Given all the data so far, experts recommend urgent policy changes to help people with long COVID.
“The population needs to be prepared, that understanding long COVID is going to be a very long and difficult process,” said Alexander Charney, MD, PhD, associate professor and the lead principal investigator of the RECOVER adult cohort at Icahn School of Medicine at Mount Sinai in New York. He said the government can do a great deal to help, including setting up a network of connected clinics treating long COVID, standardizing best practices, and sharing information.
“That would go a long way towards making sure that every person feels like they’re not too far away from a clinic where they can get treated for this particular condition,” he said.

“I will say that avoiding COVID remains the best treatment in the arsenal right now,” said Dr. Kaushal. This means masking, avoiding crowded places with poor ventilation and high exposure risk, and being up to date on vaccinations, she said.

with symptoms that have lasted 3 months or longer, according to the latest U.S. government survey done in October. More than a quarter say their condition is severe enough to significantly limit their day-to-day activities – yet the problem is only barely starting to get the attention of employers, the health care system, and policymakers.
With no cure or treatment in sight, long COVID is already burdening not only the health care system, but also the economy – and that burden is set to grow. Many experts worry about the possible long-term ripple effects, from increased spending on medical care costs to lost wages due to not being able to work, as well as the policy implications that come with addressing these issues.
“At this point, anyone who’s looking at this seriously would say this is a huge deal,” says senior Brookings Institution fellow Katie Bach, the author of a study that analyzed long COVID’s impact on the labor market.
“We need a real concerted focus on treating these people, which means both research and the clinical side, and figuring out how to build a labor market that is more inclusive of people with disabilities,” she said.
It’s not only that many people are affected. It’s that they are often affected for months and possibly even years.
The U.S. government figures suggest more than 18 million people could have symptoms of long COVID right now. The latest Household Pulse Survey by the Census Bureau and the National Center for Health Statistics takes data from 41,415 people.
A preprint of a study by researchers from City University of New York, posted on medRxiv in September and based on a similar population survey done between June 30 and July 2, drew comparable results. The study has not been peer reviewed.
More than 7% of all those who answered said they had long COVID at the time of the survey, which the researchers said corresponded to approximately 18.5 million U.S. adults. The same study found that a quarter of those, or an estimated 4.7 million adults, said their daily activities were impacted “a lot.”
This can translate into pain not only for the patients, but for governments and employers, too.
In high-income countries around the world, government surveys and other studies are shedding light on the extent to which post-COVID-19 symptoms – commonly known as long COVID – are affecting populations. While results vary, they generally fall within similar ranges.
The World Health Organization estimates that between 10% and 20% of those with COVID-19 go on to have an array of medium- to long-term post-COVID-19 symptoms that range from mild to debilitating. The U.S. Government Accountability Office puts that estimate at 10% to 30%; one of the latest studies published at the end of October in The Journal of the American Medical Association found that 15% of U.S. adults who had tested positive for COVID-19 reported current long COVID symptoms. Elsewhere, a study from the Netherlands published in The Lancet in August found that one in eight COVID-19 cases, or 12.7%, were likely to become long COVID.
“It’s very clear that the condition is devastating people’s lives and livelihoods,” WHO Director-General Tedros Adhanom Ghebreyesus wrote in an article for The Guardian newspaper in October.
“The world has already lost a significant number of the workforce to illness, death, fatigue, unplanned retirement due to an increase in long-term disability, which not only impacts the health system, but is a hit to the overarching economy … the impact of long COVID for all countries is very serious and needs immediate and sustained action equivalent to its scale.”
Global snapshot: Lasting symptoms, impact on activities
Patients describe a spectrum of persistent issues, with extreme fatigue, brain fog or cognitive problems, and shortness of breath among the most common complaints. Many also have manageable symptoms that worsen significantly after even mild physical or mental exertion.
Women appear almost twice as likely as men to get long COVID. Many patients have other medical conditions and disabilities that make them more vulnerable to the condition. Those who face greater obstacles accessing health care due to discrimination or socioeconomic inequity are at higher risk as well.
While many are older, a large number are also in their prime working age. The Census Bureau data show that people ages 40-49 are more likely than any other group to get long COVID, which has broader implications for labor markets and the global economy. Already, experts have estimated that long COVID is likely to cost the U.S. trillions of dollars and affect multiple industries.
“Whether they’re in the financial world, the medical system, lawyers, they’re telling me they’re sitting at the computer screen and they’re unable to process the data,” said Zachary Schwartz, MD, medical director for Vancouver General Hospital’s Post-COVID-19 Recovery Clinic.
“That is what’s most distressing for people, in that they’re not working, they’re not making money, and they don’t know when, or if, they’re going to get better.”
Nearly a third of respondents in the Census Bureau’s Household Pulse Survey who said they have had COVID-19 reported symptoms that lasted 3 months or longer. People between the ages of 30 and 59 were the most affected, with about 32% reporting symptoms. Across the entire adult U.S. population, the survey found that 1 in 7 adults have had long COVID at some point during the pandemic, with about 1 in 18 saying it limited their activity to some degree, and 1 in 50 saying they have faced “a lot” of limits on their activities. Any way these numbers are dissected, long COVID has impacted a large swath of the population.
Yet research into the causes and possible treatments of long COVID is just getting underway.
“The amount of energy and time devoted to it is way, way less than it should, given how many people are likely affected,” said David Cutler, PhD, professor of economics at Harvard University, Cambridge, Mass., who has written about the economic cost of long COVID. “We’re way, way underdoing it here. And I think that’s really a terrible thing.”
Population surveys and studies from around the world show that long COVID lives up to its name, with people reporting serious symptoms for months on end.
In October, Statistics Canada and the Public Health Agency of Canada published early results from a questionnaire done between spring and summer 2022 that found just under 15% of adults who had a confirmed or suspected case of COVID-19 went on to have new or continuing symptoms 3 or more months later. Nearly half, or 47.3%, dealt with symptoms that lasted a year or more. More than one in five said their symptoms “often or always” limited their day-to-day activities, which included routine tasks such as preparing meals, doing errands and chores, and basic functions such as personal care and moving around in their homes.
Nearly three-quarters of workers or students said they missed an average of 20 days of work or school.
“We haven’t yet been able to determine exactly when symptoms resolve,” said Rainu Kaushal, MD, the senior associate dean for clinical research at Weill Cornell Medicine in New York. She is co-leading a national study on long COVID in adults and children, funded by the National Institutes of Health RECOVER Initiative.
“But there does seem to be, for many of the milder symptoms, resolution at about 4-6 weeks. There seems to be a second point of resolution around 6 months for certain symptoms, and then some symptoms do seem to be permanent, and those tend to be patients who have underlying conditions,” she said.
Reducing the risk
Given all the data so far, experts recommend urgent policy changes to help people with long COVID.
“The population needs to be prepared, that understanding long COVID is going to be a very long and difficult process,” said Alexander Charney, MD, PhD, associate professor and the lead principal investigator of the RECOVER adult cohort at Icahn School of Medicine at Mount Sinai in New York. He said the government can do a great deal to help, including setting up a network of connected clinics treating long COVID, standardizing best practices, and sharing information.
“That would go a long way towards making sure that every person feels like they’re not too far away from a clinic where they can get treated for this particular condition,” he said.
But the only known way to prevent long COVID is to prevent COVID-19 infections in the first place, experts say. That means equitable access to tests, therapeutics, and vaccines.

Doctors urge screening for autoimmune disorders for patients with celiac disease
Diagnosed at age 4, Dr. Mollo has been on a gluten-free diet for 41 years, which she says has kept her healthy and may also be why she hasn’t developed other autoimmune diseases. It’s also played a part in her thinking about screening patients with CD.
“I think [physicians] should definitely be screening people with celiac disease for autoimmune disorders, especially if they see things like anemia or if a child has dropped on the growth chart and has nutrient deficiencies,” said Dr. Mollo, whose daughter also has the disease. “I would recommend that they see someone who specializes in celiac disease so they can get monitored and have regular follow-up checks for nutrient deficiencies and other autoimmune disorders.”
Dr. Mollo’s views on screening are echoed by many CD specialists and physicians, who cite multiple studies that have found that people with the disease face higher risks for diabetes, thyroid conditions, arthritis, and other autoimmune disorders.
Gastroenterologist Alessio Fasano, MD, with Massachusetts General Hospital, Boston, said there has been a “shift in the paradigm in thinking” about cross-screening for CD and autoimmune disorders. As result, he believes the answer to the question of whether to routinely do so is a no-brainer.
“The bottom line is, if you have CD, it [should be] routine that during your annual follow-ups you check for the possibility of the onset of other autoimmune disease. And people with other autoimmune diseases, like type 1 diabetes, should also be screened for CD because of the comorbidity,” said Dr. Fasano, professor of pediatrics and gastroenterology at Harvard Medical School and professor of nutrition at the Harvard School of Public Health, both in Boston. “This is what we call good clinical practice.”
Screening, despite lack of consensus guidelines
Other CD specialists differ on the need for universal cross-screening but agree that, at least in some cases, people with one autoimmune disorder should be tested for others.
Jolanda Denham, MD, a pediatric gastroenterologist affiliated with Nemours Children’s Hospital in Orlando, routinely recommends that her patients with CD be screened for certain autoimmune disorders – such as type 1 diabetes and autoimmune thyroid and liver diseases – even though medical organizations have not developed clear consensus or standard guidelines on cross-screening.
“There currently is no evidence to support the screening of celiac patients for all autoimmune and rheumatologic disorders,” she said. “It is true that celiac disease is an autoimmune disorder, and as such, there is a definite increased risk of these disorders in patients with celiac disease and vice versa.”
Echoing Dr. Denham, New York–based gastroenterologist Benjamin Lebwohl, MD, president of the Society for the Study of Celiac Disease, urges physicians to look beyond consensus guidelines and to err on the side of caution and make the best decisions for their patients on a case-by-case basis.
“Given the increased risk of certain autoimmune conditions in people with celiac disease, it behooves physicians to have a low threshold to evaluate for these conditions if any suggestive symptoms are present,” said Dr. Lebwohl, director of clinical research at the Celiac Disease Center at Columbia University, New York.
“Whether to screen for these conditions among people who are entirely without symptoms is less certain, and there is no consensus on that. But it is reasonable and common to include some basic tests with annual blood work, such as thyroid function and a liver profile, since both autoimmune thyroid disease and autoimmune liver disease can be silent early on and the patient would potentially benefit from identification and treatment of these conditions,” he said.
The American Diabetes Association and the International Society of Pediatric and Adolescent Diabetes do recommend that people with diabetes be screened for CD years after diagnosis, noted Robert Rapaport, MD, a pediatric endocrinologist, with Kravis Children’s Hospital, New York. But in a study published in 2021, he and colleagues found that this wasn’t occurring, which prompted them to recommend yearly screening.
“There is a consensus that in children with type 1 diabetes, we screen them for other autoimmune disorders, specifically for thyroid disease and celiac disease,” said Dr. Rapaport, who is also Emma Elizabeth Sullivan Professor of Pediatric Endocrinology and Diabetes at Icahn School of Medicine at Mount Sinai, New York. “But there is no consensus going the other way – for patients with celiac disease, what other autoimmune conditions they should be screened for.”
This hasn’t kept some doctors from extending cross-screening efforts to their patients.
“At our center, we screen ... for thyroid disease and autoimmune liver disease as part of routine healthcare maintenance for our celiac disease patients. We discuss symptoms of diabetes and send screening with [hemoglobin] A1c for anyone who has symptoms,” said Lui Edwin, MD, a pediatric gastroenterologist with Children’s Hospital Colorado, Aurora, and director of the Colorado Center for Celiac Disease, who delivered a lecture on CD-autoimmune screening at the International Celiac Disease Symposium in October.
“It is definitely worth screening for celiac disease in [those with] other autoimmune disorders,” Dr. Edwin added.
“The symptoms can be very heterogeneous. Diagnosing and treating celiac disease can make a huge impact with respect to symptoms, quality of life, and preventing disease-related complications,” he said.
Mounting evidence linking CD to autoimmune disorders
Many studies have linked CD to a variety of other autoimmune disorders. The association could be due to common genetic factors or because CD might lead to such conditions. Researchers have found that people diagnosed with CD later in life are more likely to develop other autoimmune disorders.
Some studies have also found that people with certain autoimmune diseases are more likely to also have CD. In addition, some individuals develop what’s known as nonceliac gluten sensitivity, which is not an autoimmune disease but a gluten intolerance not unlike lactose intolerance.
In light of these coexisting conditions in many people with CD and other autoimmune disorders, as well as the fact that the prevalence of CD is on the rise, some specialists argue that the benefits of routine cross-screening outweigh the risks.
Going gluten free has preventive advantages
In a landmark 2012 study, researchers with the Celiac Disease Center at Columbia University stopped short of recommending routine screening for the general public or asymptomatic individuals in high-prevalence groups. But they concluded that more screening of symptomatic individuals – and close relatives – would speed treatment for those with more than one autoimmune disorder.
They also noted that some studies have found that a gluten-free diet might help prevent the development of other autoimmune disorders.
Marisa Gallant Stahl, MD, a gastroenterologist with Children’s Hospital Colorado, agreed that it is important that physicians keep gluten-free diets in mind when determining which patients to cross-screen.
“The literature is mixed, but some studies suggest that treating celiac disease with a gluten-free diet actually augments the treatment and control of other autoimmune disorders [and] adherence to a gluten-free diet does reduce the risk of cancer associated with celiac disease,” she said.
Dr. Denham agreed. “Strict adherence to a gluten-free diet definitely protects against the development of enteropathy-associated T-cell lymphoma but may be protective against non-Hodgkin’s lymphoma and adenocarcinoma of the small intestine as well. All three are associated with long-term nonadherence to a gluten-free diet.”
She also noted that a gluten-free diet may help people with CD manage other autoimmune disorders, which can be complicated by CD.
“Good control of celiac disease will help prevent complications that can worsen symptoms and outcomes of concomitant autoimmune and rheumatologic disorders,” she said.
Other factors to consider
Dr. Fasano added that autoimmune disorders can be complicated by CD in cases in which oral medications or healthful foods are not properly absorbed in the intestines.
“For example, with Hashimoto’s disease, if you have hormone replacement with oral treatments and your intestines are not 100% functional because you have inflammation, then you may have a problem [with] the absorption of medications like levothyroxine,” he said.
“It’s the same story with diabetes. You don’t take insulin by mouth, but glucose [control] strongly depends on several factors, mostly what comes from the diet, and if it’s erratic, that can be a problem. ... So, the treatment of autoimmune diseases can be influenced by celiac disease,” he said.
In addition, Dr. Fasano and others believe that people with CD and other autoimmune disorders should be managed by a team of experts who can personalize the care on the basis of specific needs of the individual patient. These should include specialists, dietitians, mental health counselors, and family social workers.
“It has to be a multidisciplinary approach to maintain the good health of an individual,” Dr. Fasano said. “Celiac disease is the quintessential example in which the primary care physician needs to be the quarterback of the team, the patient is active in his or her health, and [specialists] not only deliver personalized care but also preventive intervention, particularly the prevention of comorbidities.”

“It has to be a multidisciplinary approach to maintain the good health of an individual,” Dr. Fasano said. “Celiac disease is the quintessential example in which the primary care physician needs to be the quarterback of the team, the patient is active in his or her health, and [specialists] not only deliver personalized care but also preventive intervention, particularly the prevention of comorbidities.”

Diagnosed at age 4, Dr. Mollo has been on a gluten-free diet for 41 years, which she says has kept her healthy and may also be why she hasn’t developed other autoimmune diseases. It’s also played a part in her thinking about screening patients with CD.
“I think [physicians] should definitely be screening people with celiac disease for autoimmune disorders, especially if they see things like anemia or if a child has dropped on the growth chart and has nutrient deficiencies,” said Dr. Mollo, whose daughter also has the disease. “I would recommend that they see someone who specializes in celiac disease so they can get monitored and have regular follow-up checks for nutrient deficiencies and other autoimmune disorders.”
Dr. Mollo’s views on screening are echoed by many CD specialists and physicians, who cite multiple studies that have found that people with the disease face higher risks for diabetes, thyroid conditions, arthritis, and other autoimmune disorders.
Gastroenterologist Alessio Fasano, MD, with Massachusetts General Hospital, Boston, said there has been a “shift in the paradigm in thinking” about cross-screening for CD and autoimmune disorders. As result, he believes the answer to the question of whether to routinely do so is a no-brainer.
“The bottom line is, if you have CD, it [should be] routine that during your annual follow-ups you check for the possibility of the onset of other autoimmune disease. And people with other autoimmune diseases, like type 1 diabetes, should also be screened for CD because of the comorbidity,” said Dr. Fasano, professor of pediatrics and gastroenterology at Harvard Medical School and professor of nutrition at the Harvard School of Public Health, both in Boston. “This is what we call good clinical practice.”
Screening, despite lack of consensus guidelines
Other CD specialists differ on the need for universal cross-screening but agree that, at least in some cases, people with one autoimmune disorder should be tested for others.
Jolanda Denham, MD, a pediatric gastroenterologist affiliated with Nemours Children’s Hospital in Orlando, routinely recommends that her patients with CD be screened for certain autoimmune disorders – such as type 1 diabetes and autoimmune thyroid and liver diseases – even though medical organizations have not developed clear consensus or standard guidelines on cross-screening.
“There currently is no evidence to support the screening of celiac patients for all autoimmune and rheumatologic disorders,” she said. “It is true that celiac disease is an autoimmune disorder, and as such, there is a definite increased risk of these disorders in patients with celiac disease and vice versa.”
Echoing Dr. Denham, New York–based gastroenterologist Benjamin Lebwohl, MD, president of the Society for the Study of Celiac Disease, urges physicians to look beyond consensus guidelines and to err on the side of caution and make the best decisions for their patients on a case-by-case basis.
“Given the increased risk of certain autoimmune conditions in people with celiac disease, it behooves physicians to have a low threshold to evaluate for these conditions if any suggestive symptoms are present,” said Dr. Lebwohl, director of clinical research at the Celiac Disease Center at Columbia University, New York.
“Whether to screen for these conditions among people who are entirely without symptoms is less certain, and there is no consensus on that. But it is reasonable and common to include some basic tests with annual blood work, such as thyroid function and a liver profile, since both autoimmune thyroid disease and autoimmune liver disease can be silent early on and the patient would potentially benefit from identification and treatment of these conditions,” he said.
The American Diabetes Association and the International Society of Pediatric and Adolescent Diabetes do recommend that people with diabetes be screened for CD years after diagnosis, noted Robert Rapaport, MD, a pediatric endocrinologist, with Kravis Children’s Hospital, New York. But in a study published in 2021, he and colleagues found that this wasn’t occurring, which prompted them to recommend yearly screening.
“There is a consensus that in children with type 1 diabetes, we screen them for other autoimmune disorders, specifically for thyroid disease and celiac disease,” said Dr. Rapaport, who is also Emma Elizabeth Sullivan Professor of Pediatric Endocrinology and Diabetes at Icahn School of Medicine at Mount Sinai, New York. “But there is no consensus going the other way – for patients with celiac disease, what other autoimmune conditions they should be screened for.”
This hasn’t kept some doctors from extending cross-screening efforts to their patients.
“At our center, we screen ... for thyroid disease and autoimmune liver disease as part of routine healthcare maintenance for our celiac disease patients. We discuss symptoms of diabetes and send screening with [hemoglobin] A1c for anyone who has symptoms,” said Lui Edwin, MD, a pediatric gastroenterologist with Children’s Hospital Colorado, Aurora, and director of the Colorado Center for Celiac Disease, who delivered a lecture on CD-autoimmune screening at the International Celiac Disease Symposium in October.
“It is definitely worth screening for celiac disease in [those with] other autoimmune disorders,” Dr. Edwin added.
“The symptoms can be very heterogeneous. Diagnosing and treating celiac disease can make a huge impact with respect to symptoms, quality of life, and preventing disease-related complications,” he said.
Mounting evidence linking CD to autoimmune disorders
Many studies have linked CD to a variety of other autoimmune disorders. The association could be due to common genetic factors or because CD might lead to such conditions. Researchers have found that people diagnosed with CD later in life are more likely to develop other autoimmune disorders.
Some studies have also found that people with certain autoimmune diseases are more likely to also have CD. In addition, some individuals develop what’s known as nonceliac gluten sensitivity, which is not an autoimmune disease but a gluten intolerance not unlike lactose intolerance.
In light of these coexisting conditions in many people with CD and other autoimmune disorders, as well as the fact that the prevalence of CD is on the rise, some specialists argue that the benefits of routine cross-screening outweigh the risks.
Going gluten free has preventive advantages
In a landmark 2012 study, researchers with the Celiac Disease Center at Columbia University stopped short of recommending routine screening for the general public or asymptomatic individuals in high-prevalence groups. But they concluded that more screening of symptomatic individuals – and close relatives – would speed treatment for those with more than one autoimmune disorder.
They also noted that some studies have found that a gluten-free diet might help prevent the development of other autoimmune disorders.
Marisa Gallant Stahl, MD, a gastroenterologist with Children’s Hospital Colorado, agreed that it is important that physicians keep gluten-free diets in mind when determining which patients to cross-screen.
“The literature is mixed, but some studies suggest that treating celiac disease with a gluten-free diet actually augments the treatment and control of other autoimmune disorders [and] adherence to a gluten-free diet does reduce the risk of cancer associated with celiac disease,” she said.
Dr. Denham agreed. “Strict adherence to a gluten-free diet definitely protects against the development of enteropathy-associated T-cell lymphoma but may be protective against non-Hodgkin’s lymphoma and adenocarcinoma of the small intestine as well. All three are associated with long-term nonadherence to a gluten-free diet.”
She also noted that a gluten-free diet may help people with CD manage other autoimmune disorders, which can be complicated by CD.
“Good control of celiac disease will help prevent complications that can worsen symptoms and outcomes of concomitant autoimmune and rheumatologic disorders,” she said.
Other factors to consider
Dr. Fasano added that autoimmune disorders can be complicated by CD in cases in which oral medications or healthful foods are not properly absorbed in the intestines.
“For example, with Hashimoto’s disease, if you have hormone replacement with oral treatments and your intestines are not 100% functional because you have inflammation, then you may have a problem [with] the absorption of medications like levothyroxine,” he said.
“It’s the same story with diabetes. You don’t take insulin by mouth, but glucose [control] strongly depends on several factors, mostly what comes from the diet, and if it’s erratic, that can be a problem. ... So, the treatment of autoimmune diseases can be influenced by celiac disease,” he said.
In addition, Dr. Fasano and others believe that people with CD and other autoimmune disorders should be managed by a team of experts who can personalize the care on the basis of specific needs of the individual patient. These should include specialists, dietitians, mental health counselors, and family social workers.
“It has to be a multidisciplinary approach to maintain the good health of an individual,” Dr. Fasano said. “Celiac disease is the quintessential example in which the primary care physician needs to be the quarterback of the team, the patient is active in his or her health, and [specialists] not only deliver personalized care but also preventive intervention, particularly the prevention of comorbidities.”

Is there a doctor on the plane? Tips for providing in-flight assistance
In most cases, passengers on an airline flight are representative of the general population, which means that anyone could have an emergency at any time.
as determined on the basis of in-flight medical emergencies that resulted in calls to a physician-directed medical communications center, said Amy Faith Ho, MD, MPH of Integrative Emergency Services, Dallas–Fort Worth, in a presentation at the annual meeting of the American College of Emergency Physicians.
The study authors reviewed records of 11,920 in-flight medical emergencies between Jan. 1, 2008, and Oct. 31, 2010. The data showed that physician passengers provided medical assistance in nearly half of in-flight emergencies (48.1%) and that flights were diverted because of the emergency in 7.3% of cases.
The majority of the in-flight emergencies involved syncope or presyncope (37.4% of cases), followed by respiratory symptoms (12.1%) and nausea or vomiting (9.5%), according to the study.
When a physician is faced with an in-flight emergency, the medical team includes the physician himself, medical ground control, and the flight attendants, said Dr. Ho. Requirements may vary among airlines, but all flight attendants will be trained in cardiopulmonary resuscitation (CPR) or basic life support, as well as use of automated external defibrillators (AEDs).
Physician call centers (medical ground control) can provide additional assistance remotely, she said.
The in-flight medical bag
Tools in a physician’s in-flight toolbox start with the first-aid kit. Airplanes also have an emergency medical kit (EMK), an oxygen tank, and an AED.
The minimum EMK contents are mandated by the Federal Aviation Administration, said Dr. Ho. The standard equipment includes a stethoscope, a sphygmomanometer, and three sizes of oropharyngeal airways. Other items include self-inflating manual resuscitation devices and CPR masks in thee sizes, alcohol sponges, gloves, adhesive tape, scissors, a tourniquet, as well as saline solution, needles, syringes, and an intravenous administration set consisting of tubing and two Y connectors.
An EMK also should contain the following medications: nonnarcotic analgesic tablets, antihistamine tablets, an injectable antihistamine, atropine, aspirin tablets, a bronchodilator, and epinephrine (both 1:1000; 1 injectable cc and 1:10,000; two injectable cc). Nitroglycerin tablets and 5 cc of 20 mg/mL injectable cardiac lidocaine are part of the mandated kit as well, according to Dr. Ho.
Some airlines carry additional supplies on all their flights, said Dr. Ho. Notably, American Airlines and British Airways carry EpiPens for adults and children, as well as opioid reversal medication (naloxone) and glucose for managing low blood sugar. American Airlines and Delta stock antiemetics, and Delta also carries naloxone. British Airways is unique in stocking additional cardiac medications, both oral and injectable.
How to handle an in-flight emergency
Physicians should always carry a copy of their medical license when traveling for documentation by the airline if they assist in a medical emergency during a flight, Dr. Ho emphasized. “Staff” personnel should be used. These include the flight attendants, medical ground control, and other passengers who might have useful skills, such as nursing, the ability to perform CPR, or therapy/counseling to calm a frightened patient. If needed, “crowdsource additional supplies from passengers,” such as a glucometer or pulse oximeter.
Legal lessons
Physicians are not obligated to assist during an in-flight medical emergency, said Dr. Ho. Legal jurisdiction can vary. In the United States, a bystander who assists in an emergency is generally protected by Good Samaritan laws; for international airlines, the laws may vary; those where the airline is based usually apply.
The Aviation Medical Assistance Act, passed in 1998, protects individuals from being sued for negligence while providing medical assistance, “unless the individual, while rendering such assistance, is guilty of gross negligence of willful misconduct,” Dr. Ho noted. The Aviation Medical Assistance Act also protects the airline itself “if the carrier in good faith believes that the passenger is a medically qualified individual.”
Dr. Ho disclosed no relevant financial relationships.

New recommendations for hyperglycemia management
This transcript has been edited for clarity.
I’m Dr. Neil Skolnik. Today we’re going to talk about the consensus report by the American Diabetes Association and the European Association for the Study of Diabetes on the management of hyperglycemia.
After lifestyle modifications, metformin is no longer the go-to drug for every patient in the management of hyperglycemia. It is recommended that we assess each patient’s personal characteristics in deciding what medication to prescribe. For patients at high cardiorenal risk, refer to the left side of the algorithm and to the right side for all other patients.
Cardiovascular disease. First, assess whether the patient is at high risk for atherosclerotic cardiovascular disease (ASCVD) or already has ASCVD. How is ASCVD defined? Either coronary artery disease (a history of a myocardial infarction [MI] or coronary disease), peripheral vascular disease, stroke, or transient ischemic attack.
What is high risk for ASCVD? Diabetes in someone older than 55 years with two or more additional risk factors. If the patient is at high risk for or has existing ASCVD then it is recommended to prescribe a glucagon-like peptide 1 (GLP-1) agonist with proven CVD benefit or an sodium-glucose cotransporter 2 (SGLT-2) inhibitor with proven CVD benefit.
For patients at very high risk for ASCVD, it might be reasonable to combine both agents. The recommendation to use these agents holds true whether the patients are at their A1c goals or not. The patient doesn’t need to be on metformin to benefit from these agents. The patient with reduced or preserved ejection fraction heart failure should be taking an SGLT-2 inhibitor.
Chronic kidney disease. Next up, chronic kidney disease (CKD). CKD is defined by an estimated glomerular filtration rate < 60 mL/min/1.73 m2 or a urine albumin to creatinine ratio > 30. In that case, the patient should be preferentially on an SGLT-2 inhibitor. Patients not able to take an SGLT-2 for some reason should be prescribed a GLP-1 receptor agonist.
If someone doesn’t fit into that high cardiorenal risk category, then we go to the right side of the algorithm. The goal then is achievement and maintenance of glycemic and weight management goals.
Glycemic management. In choosing medicine for glycemic management, metformin is a reasonable choice. You may need to add another agent to metformin to reach the patient’s glycemic goal. If the patient is far away from goal, then a medication with higher efficacy at lowering glucose might be chosen.
Efficacy is listed as:
- Very high efficacy for glucose lowering: dulaglutide at a high dose, semaglutide, tirzepatide, insulin, or combination injectable agents (GLP-1 receptor agonist/insulin combinations).
- High glucose-lowering efficacy: a GLP-1 receptor agonist not already mentioned, metformin, SGLT-2 inhibitors, sulfonylureas, thiazolidinediones.
- Intermediate glucose lowering efficacy: dipeptidyl peptidase 4 (DPP-4) inhibitors.
Weight management. For weight management, lifestyle modification (diet and exercise) is important. If lifestyle modification alone is insufficient, consider either a medication that specifically helps with weight management or metabolic surgery.
We particularly want to focus on weight management in patients who have complications from obesity. What would those complications be? Sleep apnea, hip or knee pain from arthritis, back pain – that is, biomechanical complications of obesity or nonalcoholic fatty liver disease. Medications for weight loss are listed by degree of efficacy:
- Very high efficacy for weight loss: semaglutide, tirzepatide.
- High efficacy for weight loss: dulaglutide and liraglutide.
- Intermediate for weight loss: GLP-1 receptor agonist (not listed above), SGLT-2 inhibitor.
- Neutral for weight loss: DPP-4 inhibitors and metformin.
Where does insulin fit in? If patients present with a very high A1c, if they are on other medications and their A1c is still not to goal, or if they are catabolic and losing weight because of their diabetes, then insulin has an important place in management.
These are incredibly important guidelines that provide a clear algorithm for a personalized approach to diabetes management.

He reported conflicts of interest with AstraZeneca, Teva, Eli Lilly, Boehringer Ingelheim, Sanofi, Sanofi Pasteur, GlaxoSmithKline, Merck, and Bayer.

Patients complain some obesity care startups offer pills, and not much else
Many Americans turn to the latest big idea to lose weight – fad diets, fitness crazes, dodgy herbs and pills, bariatric surgery, just to name a few. They’re rarely the magic solution people dream of.
Now a wave of startups offer access to a new category of drugs coupled with intensive behavioral coaching online. But already concerns are emerging.
These startups, spurred by hundreds of millions of dollars in funding from blue-chip venture capital firms, have signed up well over 100,000 patients and could reach millions more. These patients pay hundreds, if not thousands, of dollars to access new drugs, called glucagonlike peptide–1 (GLP-1) agonists, along with online coaching to encourage healthy habits.
The startups initially positioned themselves in lofty terms. “This is the last weight-loss program you’ll try,” said a 2020 marketing analysis by startup Calibrate Health, in messaging designed to reach one of its target demographics, the “working mom.” (Company spokesperson Michelle Wellington said the document does not reflect Calibrate’s current marketing strategy.)
But while doctors and patients are intrigued by the new model, some customers complain online that reality is short of the buildup: They say they got canned advice and unresponsive clinicians – and some report they couldn’t get the newest drugs.
Calibrate Health, a New York City–based startup, reported earlier in 2022 it had served 20,000 people. Another startup, Found, headquartered in San Francisco, has served 135,000 patients since July 2020, CEO Sarah Jones Simmer said in an interview. Calibrate costs patients nearly $1,600 a year, not counting the price of drugs, which can hit nearly $1,500 monthly without insurance, according to drug price savings site GoodRx. (Insurers reimburse for GLP-1agonists in limited circumstances, patients said.) Found offers a 6-month plan for nearly $600, a company spokesperson said. (That price includes generic drugs, but not the newer GLP-1 agonists, like Wegovy.)
The two companies are beneficiaries of over $200 million in combined venture funding, according to tracking by Crunchbase, a repository of venture capital investments. The firms say they’re on the vanguard of weight care, both citing the influence of biology and other scientific factors as key ingredients to their approaches.
There’s potentially a big market for these startups. Just over 4 in 10 Americans are obese, according to the Centers for Disease Control and Prevention, driving up their risk for cardiovascular conditions and type 2 diabetes. Effective medical treatments are elusive and hard to access.
Centers that provide this specialty care “are overwhelmed,” said Fatima Stanford, MD, an obesity medicine specialist at Massachusetts General in Boston, a teaching hospital affiliated with Harvard. Her own clinic has a wait list of 3,000.
Dr. Stanford, who said she has advised several of these telemedicine startups, is bullish on their potential.
Scott Butsch, MD, director of obesity medicine at the Cleveland Clinic, said the startups can offer care with less judgment and stigma than in-person peers. They’re also more convenient.
Dr. Butsch, who learned about the model through consultancies, patients, and colleagues, wonders whether the startups are operating “to strategically find which patients respond to which drug.” He said they should coordinate well with behavioral specialists, as antidepressants or other medications may be driving weight gain. “Obesity is a complex disease and requires treatments that match its complexity. I think programs that do not have a multidisciplinary team are less comprehensive and, in the long term, less effective.”
The startups market a two-pronged product: first, the new class of GLP-1 agonists. While these medications are effective at provoking weight loss, Wegovy, one of two in this class specifically approved for this purpose, is in short supply because of manufacturing difficulties, according to its maker, Novo Nordisk. Others in the category can be prescribed off label. But doctors generally aren’t familiar with the medications, Stanford said. In theory, the startups can bridge some of those gaps: They offer more specialized, knowledgeable clinicians.
Then there’s the other prong: behavioral changes. The companies use televisits and online messaging with nutritionists or coaches to help patients incorporate new diet and exercise habits. The weight loss figures achieved by participants in clinical trials for the new drugs – up to 15% of body mass – were tied to such changes, according to Novo Nordisk.
Social media sites are bursting with these startups’ ads, everywhere from podcasts to Instagram. A search of Meta’s ad library finds 40,000 ads on Facebook and Instagram between the two firms.
The ads complement people’s own postings on social media: Numerous Facebook groups are devoted to the new type of drugs – some even focused on helping patients manage side effects, like changes in their bowel movements. The buzz is quantifiable: On TikTok, mentions of the new GLP-1 agonists tripled from last June to this June, according to an analysis by investment bankers at Morgan Stanley.
There’s now a feverish, expectant appetite for these medications among the startups’ clientele. Patients often complained that their friends had obtained a drug they weren’t offered, recalled Alexandra Coults, a former pharmacist consultant for Found. Ms. Coults said patients may have perceived some sort of bait-and-switch when in reality clinical reasons – like drug contraindications – guide prescribing decisions.
Patient expectations influence care, Ms. Coults said. Customers came in with ideas shaped by the culture of fad diets and New Year’s resolutions. “Quite a few people would sign up for 1 month and not continue.”
In interviews with KHN and in online complaints, patients also questioned the quality of care they received. Some said intake – which began by filling out a form and proceeded to an online visit with a doctor – was perfunctory. Once medication began, they said, requests for counseling about side effects were slow to be answered.
Jess Garrant, a Found patient, recalled that after she was prescribed zonisamide, a generic anticonvulsant that has shown some ability to help with weight loss, she felt “absolutely weird.”
“I was up all night and my thoughts were racing,” she wrote in a blog post. She developed sores in her mouth.
She sought advice and help from Found physicians, but their replies “weren’t quick.” Nonemergency communications are routed through the company’s portal.
It took a week to complete a switch of medications and have a new prescription arrive at her home, she said. Meanwhile, she said, she went to an urgent care clinic for the mouth sores.
Found frequently prescribes generic medications – often off label – rather than just the new GLP-1 agonists, company executives said in an interview. Found said older generics like zonisamide are more accessible than the GLP-1 agonists advertised on social media and their own website. Both Dr. Butsch and Dr. Stanford said they’ve prescribed zonisamide successfully. Dr. Butsch said ramping up dosage rapidly can increase the risk of side effects.
But Kim Boyd, MD, chief medical officer of competitor Calibrate, said the older drugs “just haven’t worked.”
Patients of both companies have critiqued online and in interviews the startups’ behavioral care – which experts across the board maintain is integral to successful weight loss treatment. But some patients felt they simply had canned advice.
Other patients said they had ups and downs with their coaches. Dana Crom, an attorney, said she had gone through many coaches with Calibrate. Some were good, effective cheerleaders; others, not so good. But when kinks in the program arose, she said, the coach wasn’t able to help her navigate them. While the coach can report trouble with medications or the app, it appears those reports are no more effective than messages sent through the portal, Ms. Crom said.
And what about when her yearlong subscription ends? Ms. Crom said she’d consider continuing with Calibrate.
Relationships with coaches, given the need to change behavior, are a critical element of the business models. Patients’ results depend “on how adherent they are to lifestyle changes,” said Found’s chief medical officer, Rehka Kumar, MD.
While the startups offer care to a larger geographic footprint, it’s not clear whether the demographics of their patient populations are different from those of the traditional bricks-and-mortar model. Calibrate’s patients are overwhelmingly White; over 8 in 10 have at least an undergraduate degree; and over 8 in 10 are women, according to the company.
And its earlier marketing strategies reflected that. The September 2020 “segmentation” document laid out three types of customers the company could hope to attract: perimenopausal or menopausal women, with income ranging from $75,000 to $150,000 a year; working mothers, with a similar income; and “men.”
Isabelle Kenyon, Calibrate’s CEO, said the company now hopes to expand its reach to partner with large employers, and that will help diversify its patients.
Patients will need to be convinced that the model – more affordable, more accessible – works for them. For her part, Ms. Garrant, who no longer is using Found, reflected on her experience, writing in her blog post that she was hoping for more follow-up and a more personal approach. “I don’t think it’s a helpful way to lose weight,” she said.

Sham-controlled renal denervation trial for hypertension is a near miss
SPYRAL HTN–ON MED hits headwinds
CHICAGO – Renal denervation, relative to a sham procedure, was linked with statistically significant reductions in blood pressure in the newly completed SPYRAL HTN–ON MED trial, but several factors are likely to have worked in concert to prevent the study from meeting its primary endpoint.
Of these differences, probably none was more important than the substantially higher proportion of patients in the sham group that received additional BP-lowering medications over the course of the study, David E. Kandzari, MD, reported at the American Heart Association scientific sessions.
The SPYRAL HTN–ON MED pivotal trial followed the previously completed SPYRAL HTN–ON MED pilot study, which did show a significant BP-lowering effect on antihypertensive medications followed radiofrequency denervation. In a recent update of the pilot study, the effect was persistent out to 3 years.
In the SPYRAL HTN–ON MED program, patients on their second screening visit were required to have a systolic pressure of between 140 and 170 mm Hg on 24-hour ambulatory BP monitoring (ABPM) while taking up to three antihypertensive medications. Patients who entered the study were randomized to renal denervation or sham control while maintaining their baseline antihypertensive therapies.
The previously reported pilot study comprised 80 patients. The expansion pivotal trial added 257 more patients for a total cohort of 337 patients. The primary efficacy endpoint was based on a Bayesian analysis of change in 24-hour systolic ABPM at 6 months for those in the experimental arm versus those on medications alone. Participants from both the pilot and pivotal trials were included.
The prespecified definition of success for renal denervation was a 97.5% threshold for probability of superiority on the basis of this Bayesian analysis. However, the Bayesian analysis was distorted by differences in the pilot and expansion cohorts, which complicated the superiority calculation. As a result, the analysis only yielded a 51% probability of superiority, a level substantially below the predefined threshold.
Despite differences seen in BP control in favor of renal denervation, several factors were identified that likely contributed to the missed primary endpoint. One stood out.
“Significant differences in medication prescriptions were disproportionate in favor of the sham group,” reported Dr. Kandzari, chief of Piedmont Heart Institute, Atlanta. He said these differences, which were a violation of the protocol mandate, led to a “bias toward the null” for the primary outcome.
The failure to meet the primary outcome was particularly disappointing in the wake of the favorable pilot study and the SPYRAL HTN–OFF MED pivotal trial, which were both positive.
In the pilot study, which did not have a medication imbalance, a 7.3–mm Hg reduction (P = .004) in 24-hour ABPM was seen at 6 months. Relative reductions in office-based systolic pressure reductions for renal denervation versus sham were 6.6 mm Hg (P = .03) and 4.0 mm Hg (P = .03) for the pilot and expansions groups, respectively.
On the basis of a Win ratio derived from a hierarchical analysis of ABMP and medication burden reduction, the 1.50 advantage (P = .005) for the renal denervation arm in the newly completed SPYRAL HTN–ON MED trial was also compelling.
At study entry, the median number of medications was 1.9 in both the renal denervation and sham arms. At the end of 6 months, the median number of medications was unchanged in the experimental arm but rose to 2.1 (P = .01) in the sham group. Similarly, there was little change in the medication burden from the start to the end of the trial in the denervation group (2.8 vs. 3.0), but a statistically significant change in the sham group (2.9 vs. 3.5; P = .04).
Furthermore, the net percentage change of patients receiving medications favoring BP reduction over the course of the study did not differ between the experimental and control arms of the pilot cohort, but was more than 10 times higher among controls in the expansion group (1.9% vs. 21.8%; P < .0001).
Medication changes over the course of the SPYRAL HTN–ON MED trial were even greater in some specific subgroups. Among Black participants, for example, 14.2% of those randomized to renal denervation and 54.6% of those randomized to the sham group increased their antihypertensive therapies over the course of the study.
The COVID-19 epidemic is suspected of playing another role in the negative results, according to Dr. Kandzari. After a brief pause in enrollment, the SPYRAL HTN–ON MED trial was resumed, but approximately 80% of the expansion cohort data were collected during this period. When compared, variances in office and 24-hour ABPM were observed for participants who were or were not evaluated during COVID.
“Significant differences in 24-hour ABPM patterns pre- and during COVID may reflect changes in patient behavior and lifestyle,” Dr. Kandzari speculated.
The data from this study differ from essentially all of the other studies in the SPYRAL HTN program as well as several other sham-controlled studies with renal denervation, according to Dr. Kandzari.
The AHA-invited discussant, Ajay J. Kirtane, MD, director of the Cardiac Catheterization Laboratories at Columbia University, New York, largely agreed that several variables appeared to conspire against a positive result in this trial, but he zeroed in on the imbalance of antihypertensive medications.
“Any trial that attempts to show a difference between renal denervation and a sham procedure must insure that antihypertensive medications are the same in the two arms. They cannot be different,” he said.
As an active investigator in the field of renal denervation, Dr. Kirtane thinks the evidence does support a benefit from renal denervation, but he believes data are still needed to determine which patients are candidates.
“Renal denervation is not going to be a replacement for previous established therapies, but it will be an adjunct,” he predicted. The preponderance of evidence supports clinically meaningful reductions in BP with this approach, “but we need to determine who to consider [for this therapy] and to have realistic expectations about the degree of benefit.”
Dr. Kandzari reported financial relationships with Abbott Vascular, Ablative Solutions, Biotronik, Boston Scientific, CSI, Medtronic Cardiovascular, OrbusNeich, and Teleflex. Dr. Kirtane reported financial relationships with Abbott Vascular, Abiomed, Boston Scientific, Cardiovascular Systems, Cathworks, Chiesi, Medtronic, Opens, Philipps, Regeneron, ReCor Medical, Siemens, Spectranetics, and Zoll.

CHICAGO – Renal denervation, relative to a sham procedure, was linked with statistically significant reductions in blood pressure in the newly completed SPYRAL HTN–ON MED trial, but several factors are likely to have worked in concert to prevent the study from meeting its primary endpoint.
Of these differences, probably none was more important than the substantially higher proportion of patients in the sham group that received additional BP-lowering medications over the course of the study, David E. Kandzari, MD, reported at the American Heart Association scientific sessions.
The SPYRAL HTN–ON MED pivotal trial followed the previously completed SPYRAL HTN–ON MED pilot study, which did show a significant BP-lowering effect on antihypertensive medications followed radiofrequency denervation. In a recent update of the pilot study, the effect was persistent out to 3 years.
In the SPYRAL HTN–ON MED program, patients on their second screening visit were required to have a systolic pressure of between 140 and 170 mm Hg on 24-hour ambulatory BP monitoring (ABPM) while taking up to three antihypertensive medications. Patients who entered the study were randomized to renal denervation or sham control while maintaining their baseline antihypertensive therapies.
The previously reported pilot study comprised 80 patients. The expansion pivotal trial added 257 more patients for a total cohort of 337 patients. The primary efficacy endpoint was based on a Bayesian analysis of change in 24-hour systolic ABPM at 6 months for those in the experimental arm versus those on medications alone. Participants from both the pilot and pivotal trials were included.
The prespecified definition of success for renal denervation was a 97.5% threshold for probability of superiority on the basis of this Bayesian analysis. However, the Bayesian analysis was distorted by differences in the pilot and expansion cohorts, which complicated the superiority calculation. As a result, the analysis only yielded a 51% probability of superiority, a level substantially below the predefined threshold.
Despite differences seen in BP control in favor of renal denervation, several factors were identified that likely contributed to the missed primary endpoint. One stood out.
“Significant differences in medication prescriptions were disproportionate in favor of the sham group,” reported Dr. Kandzari, chief of Piedmont Heart Institute, Atlanta. He said these differences, which were a violation of the protocol mandate, led to a “bias toward the null” for the primary outcome.
The failure to meet the primary outcome was particularly disappointing in the wake of the favorable pilot study and the SPYRAL HTN–OFF MED pivotal trial, which were both positive.
In the pilot study, which did not have a medication imbalance, a 7.3–mm Hg reduction (P = .004) in 24-hour ABPM was seen at 6 months. Relative reductions in office-based systolic pressure reductions for renal denervation versus sham were 6.6 mm Hg (P = .03) and 4.0 mm Hg (P = .03) for the pilot and expansions groups, respectively.
On the basis of a Win ratio derived from a hierarchical analysis of ABMP and medication burden reduction, the 1.50 advantage (P = .005) for the renal denervation arm in the newly completed SPYRAL HTN–ON MED trial was also compelling.
At study entry, the median number of medications was 1.9 in both the renal denervation and sham arms. At the end of 6 months, the median number of medications was unchanged in the experimental arm but rose to 2.1 (P = .01) in the sham group. Similarly, there was little change in the medication burden from the start to the end of the trial in the denervation group (2.8 vs. 3.0), but a statistically significant change in the sham group (2.9 vs. 3.5; P = .04).
Furthermore, the net percentage change of patients receiving medications favoring BP reduction over the course of the study did not differ between the experimental and control arms of the pilot cohort, but was more than 10 times higher among controls in the expansion group (1.9% vs. 21.8%; P < .0001).
Medication changes over the course of the SPYRAL HTN–ON MED trial were even greater in some specific subgroups. Among Black participants, for example, 14.2% of those randomized to renal denervation and 54.6% of those randomized to the sham group increased their antihypertensive therapies over the course of the study.
The COVID-19 epidemic is suspected of playing another role in the negative results, according to Dr. Kandzari. After a brief pause in enrollment, the SPYRAL HTN–ON MED trial was resumed, but approximately 80% of the expansion cohort data were collected during this period. When compared, variances in office and 24-hour ABPM were observed for participants who were or were not evaluated during COVID.
“Significant differences in 24-hour ABPM patterns pre- and during COVID may reflect changes in patient behavior and lifestyle,” Dr. Kandzari speculated.
The data from this study differ from essentially all of the other studies in the SPYRAL HTN program as well as several other sham-controlled studies with renal denervation, according to Dr. Kandzari.
The AHA-invited discussant, Ajay J. Kirtane, MD, director of the Cardiac Catheterization Laboratories at Columbia University, New York, largely agreed that several variables appeared to conspire against a positive result in this trial, but he zeroed in on the imbalance of antihypertensive medications.
“Any trial that attempts to show a difference between renal denervation and a sham procedure must insure that antihypertensive medications are the same in the two arms. They cannot be different,” he said.
As an active investigator in the field of renal denervation, Dr. Kirtane thinks the evidence does support a benefit from renal denervation, but he believes data are still needed to determine which patients are candidates.
“Renal denervation is not going to be a replacement for previous established therapies, but it will be an adjunct,” he predicted. The preponderance of evidence supports clinically meaningful reductions in BP with this approach, “but we need to determine who to consider [for this therapy] and to have realistic expectations about the degree of benefit.”
