Why it might be better to be a dog person

Here’s that old debate again: Dogs or cats? You probably have your own opinion, but research presented at this year’s Digestive Disease Week may have tipped the scale by showing that children who lived with dogs may be less likely to have Crohn’s disease as adults.

The research was done by having approximately 4,300 people closely related to patients with Crohn’s disease fill out an environmental questionnaire. Using these data, the research team looked into environmental factors such as size of the families, where the home was, how many bathrooms the homes had, and quality of drinking water.

The researchers found that those who had or were exposed to dogs between the ages of 5 and 15 years were more likely to have healthy gut permeability and balanced microbes, which increased their protection against Crohn’s disease.

“Our study seems to add to others that have explored the ‘hygiene hypothesis’ which suggests that the lack of exposure to microbes early in life may lead to lack of immune regulation toward environmental microbes,” senior author Williams Turpin, PhD, said in the written statement.

The researchers aren’t sure why they didn’t get the same findings with cats, but Dr. Turpin theorized that dog owners tend to be outside more with their dogs or live in places with more green space, which are good protectors against Crohn’s disease.

It’s all good for dog owners, but do their pets’ parasites make you more attractive? Just more fuel for the ongoing debate.
 

Come for the history, stay for the fossilized parasites

Another week, another analysis of old British poop. LOTME really is your one-stop shop for all the important, hard-hitting news about historic parasites. You’re welcome, Internet.

The news this week is from Stonehenge, which is apparently kind of a big deal. Rocks in a circle, celestial calendar, cultural significance, whatever. We’re not here to talk about rocks. We’re here to talk about, uh, rocks. Smaller rocks. Specifically, coprolites, which are essentially poop turned into a rock. (Though now we’re imagining Stonehenge made out of fossilized poop rocks. Would it still be a big tourist destination? We can see both sides of the argument on that one.)

Archaeologists from the University of Cambridge have conducted an analysis of coprolites from Durrington Walls, a Neolithic settlement just a few kilometers from Stonehenge. The town dates to the same time that Stonehenge was constructed, and it’s believed that the residents were responsible for building the landmark. These coprolites, depending on what’s inside, can tell us a lot about how the builders of Stonehenge lived and, more specifically, how they ate.

In this case, the coprolites of one human and three dogs contained capillariid worm eggs. These worms come from cows, and when a human is typically infected, the eggs embed in the liver and do not pass through the body. Finding them in excrement indicates that the people were eating raw cow organs and feeding leftovers to their dogs. This is interesting, because a preponderance of pottery and cooking implements also found at the site indicates that the residents of Durrington Walls were spit-roasting or boiling their beef and pork. So the meat was cooked, but not the organs. That is an interesting dietary decision, ancient British people. Then again, modern British cuisine exists. At least now we know where they got it from.

This new research raises one other very important question: When are we going to get a full-on guided tour of all the important coprolite sites in Britain? They’ve clearly got plenty of them, and the tourist demand for ancient parasites must be sky-high. Come on, capitalism, follow through on this. We’d go.
 

Everyone lies: Food intake edition

Do you have any patients on special diets? Do you ask them if they are following those diets? Don’t bother, because they’re lying. Everyone lies about the food they eat. Everyone. Obese people lie, and nonobese people lie.

Investigators at the University of Essex in England asked 221 adults to keep food diaries, and then they checked on energy consumption by analyzing radioactive water levels in the participants’ urine over a 10-day period.

Underreporting of food consumption was rampant, even among those who were not obese. The obese subjects did underreport by a greater extent (1,200 calories per day) than did those who were not obese, who were off by only 800 calories, but the obese participants burned about 400 calories more each day than did the nonobese, so the difference was a wash.

Everyone ended up underreporting their calorie consumption by an average of about 900 calories, and the investigators were good enough to provide some food equivalents, tops on the list being three MacDonald’s cheeseburgers.

“Public health recommendations have historically relied heavily on self-reported energy intake values,” senior author Gavin Sandercock, PhD, said in a EurekAlert statement, and “recognising that the measures of energy intake are incorrect might result in the setting of more realistic targets.”

Maybe you can be more realistic with your patients, too. Go ahead and ask Mr. Smith about the burger sticking out of his coat pocket, because there are probably two more you can’t see. We’ve each got 900 calories hiding on us somewhere. Ours is usually pizza.
 

The art of the gallbladder

Ever thought you would see a portrait of a gallbladder hanging up in a gallery? Not just an artist’s rendition, but an actual photo from an actual patient? Well, you can at the Soloway Gallery in Brooklyn, N.Y., at least until June 12.

The artist? K.C. Joseph, MD, a general surgeon from St. Marie, Pa., who died in 2015. His daughter Melissa is the curator of the show and told ARTnews about the interesting connection her father had with art and surgery.

In 2010, Dr. Joseph gave his daughter a box of photos and said “Make me a famous artist,” she recalled. At first, “I was like, ‘These are weird,’ and then I put them under my bed for 10 years.”

Apparently he had been making art with his patients’ organs for about 15 years and had a system in which he put each one together. Before a surgery Dr. Joseph would make a note card with the patient’s name handwritten in calligraphy with a couple of pages taken out of the magazine from the waiting room as the backdrop. Afterward, when the patient was in recovery, the removed organ would be placed among the pages and the name card. A photo was taken with the same endoscope that was used for the procedure.

After the show’s debut, people reached out expressing their love for their photos. “I wish, before he died, I had asked him more questions about it,” Ms. Joseph told ARTnews. “I’m regretting it so much now, kicking myself.”

Who gets to take home an artsy photo of their gallbladder after getting it removed? Not us, that’s who. Each collage is a one-of-a-kind piece. They definitely should be framed and shown in an art gallery. Oh, right. Never mind.

Many adults can achieve remission of type 2 diabetes with a primary intervention consisting of a diet that emphasizes whole, plant-based foods, according to a new publication from the American College of Lifestyle Medicine (ACLM).

The document was developed to assist clinicians treating adults with type 2 diabetes, with the goal of remission using diet as a primary intervention. A panel of 15 experts from seven societies reached consensus on 69 statements.

“A healthy diet is a foundational component of current lifestyle guidelines for treatment of type 2 diabetes, but it is often overlooked because of the lack of physician training and patient awareness,” Felice A. Caldarella, MD, president of the American Association of Clinical Endocrinology (AACE), said in a press release from ACLM.

“The consensus statements produced by this panel of experts are invaluable in bringing awareness to the value of diet for diabetes remission in addition to management,” he summarized.

The initiative was cosponsored by the Endocrine Society, endorsed by AACE, and supported by the Academy of Nutrition and Dietetics. The expert panel also included representatives from the American College of Cardiology, the American Heart Association, and the American Academy of Family Physicians. It was published in the American Journal of Lifestyle Medicine.

“I think many patients would do the challenging work of making lifestyle modifications if it meant remission of [type 2 diabetes] and sparing them the burden and cost of medications or surgery,” said Amy E. Rothberg, MD, PhD, who represented the Endocrine Society on the panel.

“By changing the course of the disease, i.e., if in remission, they are unlikely to get the complications related to [type 2 diabetes],” Dr. Rothberg, professor of nutritional sciences at the University of Michigan, Ann Arbor, told this news organization.
 

Consensus on 69 statements

The panel members used a modified Delphi process to develop the consensus statement. They identified 49 articles from the literature regarding dietary interventions in adults with type 2 diabetes. They reached consensus on 69 statements that cover seven topics: definitions and basic concepts; diet and remission of type 2 diabetes; dietary specifics and types of diets; adjuvant and alternative interventions; support, monitoring, and adherence to therapy; weight loss; and payment and policy.

Dr. Rothberg identified six key areas:

• Definition of remission: Type 2 diabetes remission is defined as A1c < 6.5% for at least 3 months with no surgery, devices, or active pharmacologic therapy for lowering blood glucose, consistent with the diabetes remission timeline published in 2021 by the American Diabetes Association. Remission does not exclude the possibility of recurrence. Remission is a realistic and achievable goal for some adults with type 2 diabetes.
• High-intensity diet, short duration of diabetes: Patients are more likely to attain remission with a high-intensity diet (e.g., high level of restrictions plus frequent patient contact or counseling) accompanied by physical activity and if the patient has had diabetes for 4 years or less. A high-fiber diet is essential.
• Fewer calories, focus on plant-based foods: Calorie reduction could be achieved by reducing food volume, portion sizes, or energy density, or by using liquid meal replacements, or by a combination of these approaches. It should mainly include whole, plant-based foods (whole grains, vegetables, legumes, fruits, nuts, and seeds) and avoid or minimize meat and other animal products, refined foods, ultra-processed foods, and foods with added fats.
• A very low energy diet as initial intervention is optional: There was consensus that this approach can achieve remission, but there was not agreement that low calorie content was essential for achieving remission, Dr. Rothberg noted.
• Beyond type 2 remission: Diet as a primary intervention can also lower the risk of cardiovascular disease and improve lipoprotein profile.
• Self-management, support, and monitoring: The group recognizes the importance of patient education and support. “This can play a vital role and should be part of any comprehensive lifestyle treatment,” said Dr. Rothberg. The diet and lifestyle strategies should be acceptable to most patients, easy to adhere to, accommodate patient preferences and values, and be culturally sensitive.

Intensive lifestyle change can equate to bariatric surgery

Also invited to comment, Yehuda Handelsman, MD, who coauthored a 2020 type 2 diabetes management algorithm by AACE and the American College of Endocrinology, and was not involved with the current initiative, agrees with the importance of lifestyle in the management of type 2 diabetes but takes issue with a few points.

Most clinicians and experts do not believe that diabetes can be reversed, as such, only controlled, noted Dr. Handelsman, medical director of the Metabolic Institute of America, Tarzana, Calif.

“We always have approached type 2 diabetes treatment with lifestyle – diet, exercise, and (as of late) sleep – as the mainstay of therapy,” he said.

However, most patients do not adhere to diet modifications by 6 months and especially by 1 year, which has led to universal recommendations to add medication to lifestyle from inception, he continued.

Most clinicians have not been trained in lifestyle modalities. And many patients with type 2 diabetes are not adherent to medications, which “led to the relative success of bariatric surgery leading to remission (at least for 3-5 years).”

“Remission, which in broad terms implies the disappearance of signs and symptoms, should be a top priority for individuals with type 2 diabetes,” the consensus statement authors wrote.

“While [bariatric surgery] can induce remission in 25% to 80% of targeted patients, it carries risk and its effectiveness wanes as subjects regain lost weight,” and “more dramatic and intensive [lifestyle] change produces remission rates equivalent to bariatric surgery,” they noted.

Need for more randomized trials

Dr. Handelsman also stressed that remission may be temporary. “Three months or 6 months cannot be a measure of success. We must have at least 1 year,” he added. “In fact, there are data to show that remission requires 3 years.”

Nevertheless, the consensus statement does highlight the importance of lifestyle in remission of diabetes, he agreed.

The expert panel also noted that patients can benefit from a healthy lifestyle, even if they do not attain remission, Dr. Rothberg pointed out. 

Moving forward, the statement concludes that “there is ... an ongoing need for additional randomized controlled trials to assess sustainable plant-based dietary interventions with whole or minimally processed foods, as a primary means of treating [type 2 diabetes] with the goal of remission, as well as factors that lead to successful patient adherence and effective dissemination and implementation of such interventions.”

This study was supported by the Lisa Wendel Memorial Foundation. Dr. Rothberg has disclosed being the medical director of  Rewind, a virtual platform created for weight control with the goal to “defeat” type 2 diabetes, and a consultant for a study for which Nestle provides product. Dr. Handelsman has disclosed receiving research grants and consultant and speaker honoraria from Amarin, Amgen, Applied Therapeutic, AstraZeneca, Bayer, Boehringer Ingelheim, Corcept, Esperion, Ionis, Mankind, Merck, Merck-Pfizer, Novartis, Novo Nordisk, Regor, Sanofi, and Vertis.

The document was developed to assist clinicians treating adults with type 2 diabetes, with the goal of remission using diet as a primary intervention. A panel of 15 experts from seven societies reached consensus on 69 statements.

“A healthy diet is a foundational component of current lifestyle guidelines for treatment of type 2 diabetes, but it is often overlooked because of the lack of physician training and patient awareness,” Felice A. Caldarella, MD, president of the American Association of Clinical Endocrinology (AACE), said in a press release from ACLM.

“The consensus statements produced by this panel of experts are invaluable in bringing awareness to the value of diet for diabetes remission in addition to management,” he summarized.

The initiative was cosponsored by the Endocrine Society, endorsed by AACE, and supported by the Academy of Nutrition and Dietetics. The expert panel also included representatives from the American College of Cardiology, the American Heart Association, and the American Academy of Family Physicians. It was published in the American Journal of Lifestyle Medicine.

“I think many patients would do the challenging work of making lifestyle modifications if it meant remission of [type 2 diabetes] and sparing them the burden and cost of medications or surgery,” said Amy E. Rothberg, MD, PhD, who represented the Endocrine Society on the panel.

“By changing the course of the disease, i.e., if in remission, they are unlikely to get the complications related to [type 2 diabetes],” Dr. Rothberg, professor of nutritional sciences at the University of Michigan, Ann Arbor, told this news organization.
 

Consensus on 69 statements

The panel members used a modified Delphi process to develop the consensus statement. They identified 49 articles from the literature regarding dietary interventions in adults with type 2 diabetes. They reached consensus on 69 statements that cover seven topics: definitions and basic concepts; diet and remission of type 2 diabetes; dietary specifics and types of diets; adjuvant and alternative interventions; support, monitoring, and adherence to therapy; weight loss; and payment and policy.

Dr. Rothberg identified six key areas:

• Definition of remission: Type 2 diabetes remission is defined as A1c < 6.5% for at least 3 months with no surgery, devices, or active pharmacologic therapy for lowering blood glucose, consistent with the diabetes remission timeline published in 2021 by the American Diabetes Association. Remission does not exclude the possibility of recurrence. Remission is a realistic and achievable goal for some adults with type 2 diabetes.
• High-intensity diet, short duration of diabetes: Patients are more likely to attain remission with a high-intensity diet (e.g., high level of restrictions plus frequent patient contact or counseling) accompanied by physical activity and if the patient has had diabetes for 4 years or less. A high-fiber diet is essential.
• Fewer calories, focus on plant-based foods: Calorie reduction could be achieved by reducing food volume, portion sizes, or energy density, or by using liquid meal replacements, or by a combination of these approaches. It should mainly include whole, plant-based foods (whole grains, vegetables, legumes, fruits, nuts, and seeds) and avoid or minimize meat and other animal products, refined foods, ultra-processed foods, and foods with added fats.
• A very low energy diet as initial intervention is optional: There was consensus that this approach can achieve remission, but there was not agreement that low calorie content was essential for achieving remission, Dr. Rothberg noted.
• Beyond type 2 remission: Diet as a primary intervention can also lower the risk of cardiovascular disease and improve lipoprotein profile.
• Self-management, support, and monitoring: The group recognizes the importance of patient education and support. “This can play a vital role and should be part of any comprehensive lifestyle treatment,” said Dr. Rothberg. The diet and lifestyle strategies should be acceptable to most patients, easy to adhere to, accommodate patient preferences and values, and be culturally sensitive.

Intensive lifestyle change can equate to bariatric surgery

Also invited to comment, Yehuda Handelsman, MD, who coauthored a 2020 type 2 diabetes management algorithm by AACE and the American College of Endocrinology, and was not involved with the current initiative, agrees with the importance of lifestyle in the management of type 2 diabetes but takes issue with a few points.

Most clinicians and experts do not believe that diabetes can be reversed, as such, only controlled, noted Dr. Handelsman, medical director of the Metabolic Institute of America, Tarzana, Calif.

“We always have approached type 2 diabetes treatment with lifestyle – diet, exercise, and (as of late) sleep – as the mainstay of therapy,” he said.

However, most patients do not adhere to diet modifications by 6 months and especially by 1 year, which has led to universal recommendations to add medication to lifestyle from inception, he continued.

Most clinicians have not been trained in lifestyle modalities. And many patients with type 2 diabetes are not adherent to medications, which “led to the relative success of bariatric surgery leading to remission (at least for 3-5 years).”

“Remission, which in broad terms implies the disappearance of signs and symptoms, should be a top priority for individuals with type 2 diabetes,” the consensus statement authors wrote.

“While [bariatric surgery] can induce remission in 25% to 80% of targeted patients, it carries risk and its effectiveness wanes as subjects regain lost weight,” and “more dramatic and intensive [lifestyle] change produces remission rates equivalent to bariatric surgery,” they noted.

Need for more randomized trials

Dr. Handelsman also stressed that remission may be temporary. “Three months or 6 months cannot be a measure of success. We must have at least 1 year,” he added. “In fact, there are data to show that remission requires 3 years.”

Nevertheless, the consensus statement does highlight the importance of lifestyle in remission of diabetes, he agreed.

The expert panel also noted that patients can benefit from a healthy lifestyle, even if they do not attain remission, Dr. Rothberg pointed out. 

Moving forward, the statement concludes that “there is ... an ongoing need for additional randomized controlled trials to assess sustainable plant-based dietary interventions with whole or minimally processed foods, as a primary means of treating [type 2 diabetes] with the goal of remission, as well as factors that lead to successful patient adherence and effective dissemination and implementation of such interventions.”

This study was supported by the Lisa Wendel Memorial Foundation. Dr. Rothberg has disclosed being the medical director of  Rewind, a virtual platform created for weight control with the goal to “defeat” type 2 diabetes, and a consultant for a study for which Nestle provides product. Dr. Handelsman has disclosed receiving research grants and consultant and speaker honoraria from Amarin, Amgen, Applied Therapeutic, AstraZeneca, Bayer, Boehringer Ingelheim, Corcept, Esperion, Ionis, Mankind, Merck, Merck-Pfizer, Novartis, Novo Nordisk, Regor, Sanofi, and Vertis.

Debra Katz, CNM, has noticed a shift in the number of teenagers coming to the teen obstetrics program at St. Joseph’s Medical Center in Paterson, N.J. A decade ago, about 30 adolescents gave birth in a given month; now, that figure is closer to 20, said Ms. Katz, chief of the nurse midwifery service at the center.

Ms. Katz’s observations mirror a national trend: The rate of teen births is falling in the United States, according to a study published in Obstetrics and Gynecology.

But, there’s a catch. The adolescents who are giving birth are more likely to have obesity, mental health problems, asthma, and other conditions that can complicate their pregnancies, the research shows. Rates of delivery complications have also increased in this age group.

Ms. Katz said that, compared with adult patients, teens tend to require longer medical visits. Most patients have limited knowledge of what prenatal care entails.

“Most of these patients have never even had a female [gynecologic] exam before,” Ms. Katz said. “They come in and they’re not used to the equipment. They’re not used to the terminology.”

Also consistent with the national trends, St. Joseph’s younger patients often have mental health problems or obesity. Many also lack stable housing and adequate food.

“Unfortunately, we are seeing a greater number of patients with morbid obesity; there’s a lot of bipolar disease; here’s a lot of depression; there’s a lot of anxiety,” Ms. Katz said. “And we also have a bit of PTSD [post traumatic stress disorder] as well.”

These factors make clinical practice more complex, according to the authors of the new study. “To optimize adolescent pregnancy outcomes, prenatal care will likely need to provide increasingly complex clinical management in addition to addressing outreach challenges of this population,” the authors of the new study write.

At St. Joseph’s, teens receive prenatal care in a group setting with other patients who are due to deliver in the same month. This model, called CenteringPregnancy, can increase self-esteem, build community, and may improve patient outcomes, Ms. Katz said. The program uses a team approach that includes a dietitian and social worker to address social support needs.
 

Shifting health status

To characterize delivery hospitalization trends for patients aged 11-19 years, Anna P. Staniczenko, MD, with Columbia University Irving Medical Center, New York, and her colleagues conducted a cross-sectional analysis of data from the 2000-2018 National Inpatient Sample.

Of more than 73 million estimated delivery hospitalizations during that period, 88,363 occurred in patients aged 11-14 years, and 6,359,331 were among patients aged 15-19 years.

Deliveries among patients aged 11-14 years decreased from 2.1 per 1,000 to 0.4 per 1,000 during the time frame. Deliveries among patients aged 15-19 years decreased from 11.5% of all deliveries to 4.8% over the study period.

Among patients aged 11-19 years, rates of comorbidities significantly increased from 2000 to 2018, the researchers found. The prevalence of obesity increased from 0.2% to 7.2%, asthma increased from 1.6% to 7%, while mental health conditions increased from 0.5% to 7.1%.

Severe maternal morbidity, defined as a patient having at least one of 20 conditions, including stroke, heart failure, and sepsis, increased from 0.5% to 0.7%. The rate of postpartum hemorrhage increased from 2.9% to 4.7%, the rate of cesarean delivery increased from 15.2% to 19.5%, and that of hypertensive disorders of pregnancy increased from 7.5% to 13.7%.
 

An often overlooked group

Adolescent pregnancies are more common in the United States than in other wealthy nations, and about 80% are unintended. In addition to the growth in comorbid conditions, adolescent mothers are at an increased risk of living under the poverty line, and children born to teen moms may be at increased risk for adverse pediatric outcomes.

Still, these pregnancies “may be planned and desired. ... It is unclear that there is an ‘ideal’ rate of pregnancy for this age group,” the study authors write.

Prior research has shown an increase in rates of chronic conditions among adults giving birth, but, “from what I could tell, this is really the first data” on chronic conditions in the pediatric obstetric population, said Lindsay K. Admon, MD, an ob.gyn. at the University of Michigan, Ann Arbor, who wrote an editorial accompanying the journal article.
 

Behind the decline

That there are fewer teen deliveries may be because the adolescent population is savvier about contraceptive methods. In addition, the Affordable Care Act expanded insurance coverage of contraception, said Stephanie Teal, MD, MPH, chair of obstetrics and gynecology and reproductive biology at University Hospitals Cleveland Medical Center and Case Western Reserve University School of Medicine, Cleveland.

Dr. Teal was involved in the Colorado Family Planning Initiative, a state effort that showed that long-acting reversible contraception was effective and acceptable to young people.

“We are definitely seeing more adolescents who use birth control the first time they have sex,” Dr. Teal told this news organization. “When I started in practice, it was fairly uncommon that I would see a teenager who was sexually active who was consistently using a birth control method. And now they just look at me, roll their eyes, and are, like, ‘Duh, of course. He uses condoms, and I have an IUD.’ ”

To the extent that these deliveries include unintended pregnancies, the data may point to a need for clinicians to provide contraceptive education to adolescents with chronic conditions, according to Dr. Admon.
 

Abortion shifts

If U.S. Supreme Court rulings and state laws further limit access to contraception or abortion, the result could lead to more teen deliveries, Dr. Admon said.

While the adolescent birth rate has plummeted, the teen abortion rate has not increased, Dr. Teal said.

“Pregnancy is a time of health risk for women, and it’s getting riskier,” she said. “Our concern is that if people are having to go through a pregnancy that they don’t feel physically or financially or emotionally prepared to go through, that we will see an increase in these kinds of adverse health outcomes with birth.”

One study author has a leadership role on an American College of Obstetricians and Gynecologists safe motherhood initiative that has received unrestricted funding from Merck for Mothers. Another author has ties to Delfina Care, and one is on the board of directors of Planned Parenthood of Greater New York. Dr. Admon receives funding from the Agency for Healthcare Research and Quality and the National Institutes of Health. Dr. Teal has received grants from Merck, Bayer Healthcare, Sebela, and Medicines360 and personal fees from Merck and from Bayer Healthcare. Ms. Katz has disclosed no relevant financial relationships.

Tirzepatide (Mounjaro) – the new twincretin approved by the Food and Drug Administration for glycemic control in patients with type 2 diabetes – was priced by Lilly, the company that will market the drug, at a list price of $974.33 for four weekly doses regardless of dose size, a cost that adds up to about $12,666 per year, according to a statement made on May 20 by a Lilly spokesperson.

This price puts tirzepatide, which combines the activity of two of the primary human incretins in one molecule, roughly in the same ballpark as what might be its main competitor, semaglutide (Ozempic) for type 2 diabetes, which retails at many U.S. pharmacies for about $925 for four weekly doses, or about $12,025 per year, although Ozempic’s posted retail price is about $100 higher for four doses.

According to the Lilly spokesperson, discount programs could reduce the monthly out-of-pocket cost for patients to as little as $25.

Tirzepatide, which received approval from the FDA on May 13, is a dual glucagonlike peptide–1 (GLP-1) receptor agonist and glucose-dependent insulinotropic polypeptide agonist. Several GLP-1 receptor agonists are already approved in the United States, including semaglutide, which is indicated as Wegovy for weight loss in patients with obesity regardless of diabetes status.

Misinformation about nirmatrelvir/ritonavir (Paxlovid, Pfizer) for treating mild to moderate COVID-19 in patients at high risk for severe disease is feeding misunderstanding among prescribers and patients, two experts from the Infectious Diseases Society of America (IDSA) have said.

They briefed reporters on potential drug interactions and uncommon cases of a “rebound” effect with the drug, which was granted emergency use authorization by the Food and Drug Administration last December for patients at least 12 years old.

The drug combination works “like a pair of scissors chopping up proteins that are made as the virus replicates inside of cells. Inhibiting that enzyme leads to the cessation of replication,” said Jason C. Gallagher, PharmD, of Temple University School of Pharmacy, Philadelphia.

That’s important because other treatments that target the spike protein, such as monoclonal antibodies, can lose their efficacy as the virus changes. He said that while that’s not impossible for Paxlovid, “we have not seen variants emerging that are resistant to it.”
 

Potential drug interactions

IDSA recently published updated guidance on potential interactions between Paxlovid and the top 100 drugs, and important considerations for prescribing.

“There is a concern that people have not been prescribing it because of fear of these interactions,” Dr. Gallagher said, explaining that, while in some cases those fears may be valid, in many instances the interaction is manageable.

One example is in two popular statins for heart disease, lovastatin and simvastatin.

“That’s an interaction that can be managed by holding [those drugs] for the 5 days that someone receives Paxlovid,” he said.

Misinformation also is circulating about distribution status of Paxlovid, Dr. Gallagher said.

“We’re in a very different state from that standpoint than we were a month or 2 months ago,” he said, adding that it is widely available in not all but a large number of pharmacies throughout the United States.

He emphasized the importance of drug reconciliation, as many patients will go to a different pharmacy for Paxlovid than they might for their usual prescriptions, so without a full accounting of prescriptions and supplements potential interactions may be missed.
 

Important interactions to watch

Melanie Thompson, MD, cochair of the HIVMA/IDSA HIV Primary Care Guidance Panel, highlighted some classes of drugs to watch, among them the antiarrhythmics, most of which are contraindicated with Paxlovid.

There are also important interactions with a number of cancer drugs, and consults with oncologists will be critical, she said.

“Likewise, people who have had transplants are likely to be on drugs that have significant ritonavir interactions,” Dr. Thompson said.

People on ergot drugs for migraine cannot take Paxlovid, she said, and “people who take colchicine for gout have to be very careful.”

She said it’s better not to use colchicine while taking Paxlovid, as it is contraindicated, “but it can be managed in certain circumstances with substantial dose reduction.”

A number of mental health drugs can be managed with Paxlovid, Dr. Thompson said. For the antipsychotic drug quetiapine, (Seroquel), a “substantial decrease in dose is required.”
 

Viagra for ED can be managed

Use of Viagra depends on why it’s being used, Dr. Thompson said. If it’s used for pulmonary hypertension, it is used at a very high dose and that is contraindicated. But if used for erectile dysfunction, the dose needs to be managed when people are on Paxlovid.

She said prescribers must know the kidney function of patients.

“There is a dose reduction that is required if people have impaired kidney function but below a certain level of function, which is 30 mL/min, it’s not recommended to give Paxlovid.”

Dr. Thompson highlighted two other websites for thorough, printable information on drug-drug interactions with Paxlovid: the University of Liverpool’s drug interaction checker and a printable handout from the University of Waterloo in Ontario, Canada.

“We need a 24/7 clinician hotline for Paxlovid to really make it accessible,” she said.
 

No data yet on ‘rebound’ effect

As to a few recent reports of a “rebound” effect, of people developing COVID-19 symptoms after completing a course of Paxlovid, there are not enough data yet to determine a clear pattern or cause.

“All we have are anecdotal data,” Dr. Thompson said. Current questions for study include whether the 5-day course is not long enough, she said, and whether people more at risk should be given a second course of Paxlovid if they do rebound.

Dr. Gallagher said it’s important to remember that the therapy goal of the drug is to prevent hospitalizations and deaths, and while any rebound is problematic, “it’s possible the use of the medication has already saved a life.”

Dr. Gallagher and Dr. Thompson report no relevant financial relationships.

Misinformation about nirmatrelvir/ritonavir (Paxlovid, Pfizer) for treating mild to moderate COVID-19 in patients at high risk for severe disease is feeding misunderstanding among prescribers and patients, two experts from the Infectious Diseases Society of America (IDSA) have said.

They briefed reporters on potential drug interactions and uncommon cases of a “rebound” effect with the drug, which was granted emergency use authorization by the Food and Drug Administration last December for patients at least 12 years old.

The drug combination works “like a pair of scissors chopping up proteins that are made as the virus replicates inside of cells. Inhibiting that enzyme leads to the cessation of replication,” said Jason C. Gallagher, PharmD, of Temple University School of Pharmacy, Philadelphia.

That’s important because other treatments that target the spike protein, such as monoclonal antibodies, can lose their efficacy as the virus changes. He said that while that’s not impossible for Paxlovid, “we have not seen variants emerging that are resistant to it.”
 

Potential drug interactions

IDSA recently published updated guidance on potential interactions between Paxlovid and the top 100 drugs, and important considerations for prescribing.

“There is a concern that people have not been prescribing it because of fear of these interactions,” Dr. Gallagher said, explaining that, while in some cases those fears may be valid, in many instances the interaction is manageable.

One example is in two popular statins for heart disease, lovastatin and simvastatin.

“That’s an interaction that can be managed by holding [those drugs] for the 5 days that someone receives Paxlovid,” he said.

Misinformation also is circulating about distribution status of Paxlovid, Dr. Gallagher said.

“We’re in a very different state from that standpoint than we were a month or 2 months ago,” he said, adding that it is widely available in not all but a large number of pharmacies throughout the United States.

He emphasized the importance of drug reconciliation, as many patients will go to a different pharmacy for Paxlovid than they might for their usual prescriptions, so without a full accounting of prescriptions and supplements potential interactions may be missed.
 

Important interactions to watch

Melanie Thompson, MD, cochair of the HIVMA/IDSA HIV Primary Care Guidance Panel, highlighted some classes of drugs to watch, among them the antiarrhythmics, most of which are contraindicated with Paxlovid.

There are also important interactions with a number of cancer drugs, and consults with oncologists will be critical, she said.

“Likewise, people who have had transplants are likely to be on drugs that have significant ritonavir interactions,” Dr. Thompson said.

Does having had a COVID-19 infection increase your risk for the development of diabetes subsequently? Some data say yes and other data say no. No matter what, it’s obviously important to screen people for diabetes routinely, pandemic or not. Remember, screening should start at age 35.

For over a decade, we have known that SARS-type viruses bind to beta cells. This could cause either direct damage to the beta cell or in some way trigger beta cell autoimmunity. We also know that COVID-19 infection increases the levels of inflammatory mediators, which could cause damage to beta cells and potentially to insulin receptors. There is a potential that having had a COVID-19 infection could increase rates of developing type 1 and/or type 2 diabetes.

However, there are other possible causes for people to develop diabetes after having a COVID-19 infection. A COVID-19 infection could cause one to seek medical care, unmasking latent type 1 and/or type 2 diabetes by causing infection-related insulin resistance and worsening preexisting mild hypoglycemia. In addition, people could have sought more medical care in the years since the pandemic has been ebbing, which may make it look like cases have increased.

For example, during the worst of the pandemic, I had multiple referrals for “COVID-19–caused new-onset diabetes” only to find that the patient had an A1c level above 10% and a history of mildly elevated blood glucose levels. This suggests to me that COVID-19 did not cause the diabetes per se but rather worsened an underlying glucose abnormality.

Since the pandemic has improved, I have also seen people diagnosed with type 2 diabetes that I think is associated with pandemic-related weight gain and inactivity.

The bigger issue is what is happening to people after COVID-19 infection who lack risk factors. What about those who we didn’t think were at high risk to get diabetes to begin with and didn’t have prediabetes?

An article by Xie and Al-Aly in The Lancet Diabetes & Endocrinology showed an increase in rates of diabetes in a large VA cohort among those who had a COVID-19 infection compared with both a contemporaneous control who did not have COVID-19 and a historical control. The researchers looked at the patient data 1 year after they’d had COVID-19, so it wasn’t the immediate post–COVID-19 phase but several months later.

They found that the risk for incident type 2 diabetes development was increased by 40% after adjusting for many risk factors. This included individuals who didn’t have traditional risk factors before they developed type 2 diabetes.

What does this mean clinically? First, pandemic or not, people need screening for diabetes and encouragement to have a healthy lifestyle. There may be an increased risk for the diagnosis of type 2 diabetes after COVID-19 infection due to a variety of different mechanisms.

As for people with type 1 diabetes, we also don’t know if having a COVID-19 infection increases their risk. We do know that there was an increase in the severity of diabetic ketoacidosis presentation during the pandemic, so we need to be sure that we reinforce sick-day rules with our patients with type 1 diabetes and that all individuals with type 1 diabetes have the ability to test their ketone levels at home.

In people with new-onset diabetes, whether type 1 or type 2, caused by COVID-19 or not, we need to treat appropriately based on their clinical situation.

Data from registries started during the pandemic will provide more definitive answers and help us find out if there is a relationship between having had COVID-19 infection and developing diabetes.

Perhaps that can help us better understand the mechanisms behind the development of diabetes overall.

She disclosed ties with Abbott Diabetes Care, AstraZeneca, Becton Dickinson, Boehringer Ingelheim Pharmaceuticals, Dexcom, Eli Lilly, Lexicon Pharmaceuticals, Livongo, MannKind Corporation, Medscape, Merck, Novo Nordisk, Omada Health, OptumHealth, Sanofi, and Zafgen.

MADRID – There is increasing evidence of the impact that SARS-CoV-2 infection has on patients with diabetes. It involves the relationship between COVID-19 and new diagnoses of diabetes and blood glucose disorders, among others, in the post–COVID-19 period. These topics were addressed at the XXXIII National Congress of the Spanish Diabetes Society. They were also the central theme of the inaugural conference, Pancreatic Involvement During COVID-19: From Preclinical Studies to Clinical Relevance, which was led by Alexander Kleger, MD, PhD, head of the department of pancreatology at the Ulm (Germany) University Clinic for Internal Medicine.

The chair of the scientific committee of the congress, Franz Martín, MD, launched the conference by noting that the work of Dr. Kleger and his team has made it possible to ascertain that SARS-CoV-2 can infect pancreatic beta cells that produce insulin. This observation may help in understanding why patients with COVID-19 sometimes experience symptoms related to greater difficulty regulating blood glucose.

“In addition, the German expert and his group have described the abnormalities that occur in beta cells when they are infected by SARS-CoV-2, something especially important, given that knowledge of these abnormalities may be of great importance to understanding the possible appearance of more cases of diabetes in the future,” Dr. Martín added.

“Our data identify the human pancreas as a target of SARS-CoV-2 infection and suggest that pancreatic beta cell involvement could contribute to the metabolic dysregulation seen in COVID-19 patients,” Dr. Kleger pointed out.

In his speech, Dr. Kleger reviewed the evidence on the effects of SARS-CoV-2 that has been garnered since the start of the pandemic, and he presented his research group’s findings on the impact at the pancreatic level.

“Since March 2020, it has been seen that COVID-19 affected the pancreas, and studies published in August of that same year clearly spoke of both a worsening of diabetes and an increase in new cases of this disease diagnosed after SARS-CoV-2 infection. Also, the data showed how hospitalized patients with no previous history of diabetes experienced rapid increases in glucose levels 5 days after admission,” Dr. Kleger said.
 

Angiotensin-converting enzyme 2

As an example of the pace at which evidence on the pancreatic impact of this virus has been evolving, Dr. Kleger referred to early studies that found no angiotensin-converting enzyme 2 receptor on cells of the endocrine and exocrine pancreas. “To our surprise, in our work, we did observe the obvious presence of angiotensin-converting enzyme 2 specifically expressed in human pancreatic beta cells, something confirmed by other investigations. Another surprising aspect was verifying that the viral infection lasts longer in the pancreas than in the lungs,” said the expert.

These findings caused the researchers to realize that SARS-CoV-2 may be directly or indirectly associated with diabetes. “It is currently the subject of debate whether it may be a direct effect, infecting or directly reaching the pancreatic beta cells, or whether this involvement is a result of the effect of the infection at systemic level, in the context of the cytokine storm and the proinflammatory environment derived from it. Our current challenge is to confirm whether this virus can really replicate in pancreatic beta cells and to assess the possible existence of reinfections, among other aspects,” said Dr. Kleger.

Along with these “developing areas of knowledge,” there are several certainties regarding the link between diabetes and COVID-19. Dr. Kleger summarized the most relevant one. “Preexisting diabetes is known to be a highly prevalent comorbidity seen in 11%-22% of patients and increases the risk of severe disease and mortality.

“SARS-CoV-2 infection has also been shown to affect the exocrine pancreas, manifesting as pancreatitis in 5% of critically ill patients with COVID-19, as well as enlargement of the pancreas and abnormal levels of amylase or lipase in 7.5%-17% of patients.

“Furthermore, it is obvious that SARS-CoV-2 infection produces glycometabolic dysfunction in these patients, with increased hyperglycemia in people with type 2 diabetes and ketoacidosis in 2%-6.4% of patients with and without diabetes.”
 

After recovery

The most recent research reveals the persistence of this dysregulation long after recovery from COVID-19. “We’ve seen that in a significant proportion of patients, hyperglycemia is maintained for some time; in the specific case of hospitalized patients [without the need for assisted ventilation or other intensive care requirements], for up to more than 2 months after overcoming the illness.

“In the same way, there are studies that have shown that insulin resistance and hyperstimulation of pancreatic beta cells remain at pathological levels in the post–COVID-19 phase. And in line with increased insulin resistance, signs of hyperinflammation have also been detected in these patients.”

Dr. Kleger noted that another research area is the increased incidence of newly diagnosed diabetes after recovery from SARS-CoV-2 infection, “something that seems to be correlated with how severely the disease has been experienced and also depending on whether hospitalization or intensive care was needed. Likewise, retrospective studies have shown that the risk of developing type 2 diabetes is higher in COVID-19 patients, compared with those with other respiratory infections. Regarding the incidence of type 1 diabetes, there is evidence, particularly in the case of children, of a clear correlation between the pandemic waves and the increase in cases.

“Therefore, and in view of this data, we could say that, with regard to the involvement of SARS-CoV-2 in pancreatic beta cells, something is up, but we are not yet able to fully understand what it is. What can be confirmed based on the numerous studies carried out in this regard is that COVID-19 produces a metabolic dysregulation [hyperglycemia, insulin resistance, diabetic ketoacidosis] which in turn favors the development of diabetes in patients with no history of this disease,” said Dr. Kleger.

“Likewise, everything points to the existence of a definitively feasible infection in pancreatic beta cells associated with SARS-CoV-2, but there are still unknown aspects of the physiology that explain this effect that remain the subject of debate and deserve future studies,” he concluded.
 

Consequences of the pandemic

The experts agreed that, although COVID-19 is no longer at the center of specialist care, it is still a subject of investigation. On the conference’s opening day, an update was made on the approach to diabetes.

Care activity is gradually recovering as the time that professionals devote to COVID-19 care is reduced, “but it will take time to catch up with the care activities not carried out during the pandemic, and, unfortunately, in the coming years, we will see the repercussion of the lack or reduction of care during these years,” stressed the SED chair, Antonio Pérez Pérez, MD, director of endocrinology and nutrition of Hospital de la Santa Creu i Sant Pau, Barcelona.

Dr. Pérez stressed that the pandemic has revealed health system deficiencies in diabetes care. He added that the impact of COVID-19 on diabetes (resulting from the effects of the infection itself or from the inadequacy of prevention, diagnosis, and treatment measures) fostered a deterioration of metabolic control and a delay in the diagnosis of the disease and its complications.

“All this contributes to the fact that we currently continue to see patients with complications, especially in the case of type 2 diabetes, with more serious decompensations and diagnoses in more advanced stages of the disease. This impact has been more significant in older people from disadvantaged areas and with less capacity for self-monitoring and self-adjustment of treatment,” he added.

Describing lessons learned through the experiences accumulated in diabetes care during the pandemic, Dr. Pérez highlighted the push for virtual consultations, accessibility to drugs prescribed in electronic prescriptions, and the use of educational resources online and of telemedicine tools. “The need to invest in the health sector has also been assumed, endowing it with robustness in well-trained health personnel, to promote health education, boost efficient health organization, and invest in innovation aimed at facilitating care.”

Dr. Kleger and Dr. Pérez disclosed no relevant financial relationships.

Along with these “developing areas of knowledge,” there are several certainties regarding the link between diabetes and COVID-19. Dr. Kleger summarized the most relevant one. “Preexisting diabetes is known to be a highly prevalent comorbidity seen in 11%-22% of patients and increases the risk of severe disease and mortality.

“SARS-CoV-2 infection has also been shown to affect the exocrine pancreas, manifesting as pancreatitis in 5% of critically ill patients with COVID-19, as well as enlargement of the pancreas and abnormal levels of amylase or lipase in 7.5%-17% of patients.

“Furthermore, it is obvious that SARS-CoV-2 infection produces glycometabolic dysfunction in these patients, with increased hyperglycemia in people with type 2 diabetes and ketoacidosis in 2%-6.4% of patients with and without diabetes.”
 

After recovery

The most recent research reveals the persistence of this dysregulation long after recovery from COVID-19. “We’ve seen that in a significant proportion of patients, hyperglycemia is maintained for some time; in the specific case of hospitalized patients [without the need for assisted ventilation or other intensive care requirements], for up to more than 2 months after overcoming the illness.

“In the same way, there are studies that have shown that insulin resistance and hyperstimulation of pancreatic beta cells remain at pathological levels in the post–COVID-19 phase. And in line with increased insulin resistance, signs of hyperinflammation have also been detected in these patients.”

Dr. Kleger noted that another research area is the increased incidence of newly diagnosed diabetes after recovery from SARS-CoV-2 infection, “something that seems to be correlated with how severely the disease has been experienced and also depending on whether hospitalization or intensive care was needed. Likewise, retrospective studies have shown that the risk of developing type 2 diabetes is higher in COVID-19 patients, compared with those with other respiratory infections. Regarding the incidence of type 1 diabetes, there is evidence, particularly in the case of children, of a clear correlation between the pandemic waves and the increase in cases.

“Therefore, and in view of this data, we could say that, with regard to the involvement of SARS-CoV-2 in pancreatic beta cells, something is up, but we are not yet able to fully understand what it is. What can be confirmed based on the numerous studies carried out in this regard is that COVID-19 produces a metabolic dysregulation [hyperglycemia, insulin resistance, diabetic ketoacidosis] which in turn favors the development of diabetes in patients with no history of this disease,” said Dr. Kleger.

“Likewise, everything points to the existence of a definitively feasible infection in pancreatic beta cells associated with SARS-CoV-2, but there are still unknown aspects of the physiology that explain this effect that remain the subject of debate and deserve future studies,” he concluded.
 

Consequences of the pandemic

The experts agreed that, although COVID-19 is no longer at the center of specialist care, it is still a subject of investigation. On the conference’s opening day, an update was made on the approach to diabetes.

Care activity is gradually recovering as the time that professionals devote to COVID-19 care is reduced, “but it will take time to catch up with the care activities not carried out during the pandemic, and, unfortunately, in the coming years, we will see the repercussion of the lack or reduction of care during these years,” stressed the SED chair, Antonio Pérez Pérez, MD, director of endocrinology and nutrition of Hospital de la Santa Creu i Sant Pau, Barcelona.

Dr. Pérez stressed that the pandemic has revealed health system deficiencies in diabetes care. He added that the impact of COVID-19 on diabetes (resulting from the effects of the infection itself or from the inadequacy of prevention, diagnosis, and treatment measures) fostered a deterioration of metabolic control and a delay in the diagnosis of the disease and its complications.

“All this contributes to the fact that we currently continue to see patients with complications, especially in the case of type 2 diabetes, with more serious decompensations and diagnoses in more advanced stages of the disease. This impact has been more significant in older people from disadvantaged areas and with less capacity for self-monitoring and self-adjustment of treatment,” he added.

Describing lessons learned through the experiences accumulated in diabetes care during the pandemic, Dr. Pérez highlighted the push for virtual consultations, accessibility to drugs prescribed in electronic prescriptions, and the use of educational resources online and of telemedicine tools. “The need to invest in the health sector has also been assumed, endowing it with robustness in well-trained health personnel, to promote health education, boost efficient health organization, and invest in innovation aimed at facilitating care.”

Dr. Kleger and Dr. Pérez disclosed no relevant financial relationships.

MADRID – There is increasing evidence of the impact that SARS-CoV-2 infection has on patients with diabetes. It involves the relationship between COVID-19 and new diagnoses of diabetes and blood glucose disorders, among others, in the post–COVID-19 period. These topics were addressed at the XXXIII National Congress of the Spanish Diabetes Society. They were also the central theme of the inaugural conference, Pancreatic Involvement During COVID-19: From Preclinical Studies to Clinical Relevance, which was led by Alexander Kleger, MD, PhD, head of the department of pancreatology at the Ulm (Germany) University Clinic for Internal Medicine.

The chair of the scientific committee of the congress, Franz Martín, MD, launched the conference by noting that the work of Dr. Kleger and his team has made it possible to ascertain that SARS-CoV-2 can infect pancreatic beta cells that produce insulin. This observation may help in understanding why patients with COVID-19 sometimes experience symptoms related to greater difficulty regulating blood glucose.

“In addition, the German expert and his group have described the abnormalities that occur in beta cells when they are infected by SARS-CoV-2, something especially important, given that knowledge of these abnormalities may be of great importance to understanding the possible appearance of more cases of diabetes in the future,” Dr. Martín added.

“Our data identify the human pancreas as a target of SARS-CoV-2 infection and suggest that pancreatic beta cell involvement could contribute to the metabolic dysregulation seen in COVID-19 patients,” Dr. Kleger pointed out.

In his speech, Dr. Kleger reviewed the evidence on the effects of SARS-CoV-2 that has been garnered since the start of the pandemic, and he presented his research group’s findings on the impact at the pancreatic level.

“Since March 2020, it has been seen that COVID-19 affected the pancreas, and studies published in August of that same year clearly spoke of both a worsening of diabetes and an increase in new cases of this disease diagnosed after SARS-CoV-2 infection. Also, the data showed how hospitalized patients with no previous history of diabetes experienced rapid increases in glucose levels 5 days after admission,” Dr. Kleger said.
 

Angiotensin-converting enzyme 2

As an example of the pace at which evidence on the pancreatic impact of this virus has been evolving, Dr. Kleger referred to early studies that found no angiotensin-converting enzyme 2 receptor on cells of the endocrine and exocrine pancreas. “To our surprise, in our work, we did observe the obvious presence of angiotensin-converting enzyme 2 specifically expressed in human pancreatic beta cells, something confirmed by other investigations. Another surprising aspect was verifying that the viral infection lasts longer in the pancreas than in the lungs,” said the expert.

These findings caused the researchers to realize that SARS-CoV-2 may be directly or indirectly associated with diabetes. “It is currently the subject of debate whether it may be a direct effect, infecting or directly reaching the pancreatic beta cells, or whether this involvement is a result of the effect of the infection at systemic level, in the context of the cytokine storm and the proinflammatory environment derived from it. Our current challenge is to confirm whether this virus can really replicate in pancreatic beta cells and to assess the possible existence of reinfections, among other aspects,” said Dr. Kleger.

The diverse effects of obesity on lung health and disease are increasingly being teased apart, with researchers honing in on the impact of metabolic dysfunction, circulating inflammatory factors produced by adipose tissue, lipid handling, and other factors – in addition to body mass index – that are associated with the obese state.

“The bird’s eye view is that obesity completely changes lung health. It’s something we’ve only recently begun to appreciate,” said Anne E. Dixon, MA, BM, BCh, director of the Vermont Lung Center at the University of Vermont, Burlington, who is focused on the research field of obesity and lung disease.

OSA and OHS

“With sleep apnea we tend to focus on anatomic considerations, but there may be relationships or interactions between obesity and neuromuscular function and neuroventilatory control,” Susheel P. Patil, MD, PhD, director of the sleep medicine program for University Hospitals and assistant professor at Case Western Reserve University, Cleveland, said in an interview.

Some studies suggest, for instance, that TNF-alpha can increase obstructive sleep apnea (OSA) susceptibility and severity through its neuroventilatory modulating properties during sleep. And the potential for additional proinflammatory cytokines produced by adipose tissue to similarly affect upper airway neuroventilatory control is an “intriguing line” of inquiry for researchers in the sleep apnea space, he said.

Leptin is of interest particularly in obesity hypoventilation syndrome (OHS), which is characterized by chronic daytime hypercapnia. Best known as a satiety hormone, leptin is produced by adipose tissue and suppresses appetite at the central nervous system level. But it has long been known that leptin also affects ventilation and the control of breathing.

When transported across the blood-brain barrier, leptin increases the hypercapnic ventilatory response, Babak Mokhlesi, MD, MSc, codirector of the Rush Lung Center and chief of pulmonary, critical care, and sleep medicine at Rush University Medical Center in Chicago, said in an interview.

Research suggests that patients with OHS may have resistance to leptin at the central nervous system level – with leptin not reaching the sites of ventilatory control. This is a “prevailing theory” and could explain why these patients “do not augment their ventilation to maintain homeostasis, normal levels of CO₂,” Dr. Mokhlesi said.

“Why some patients with severe obesity develop CO₂ retention while others do not is not fully understood,” he said, noting that patients with OHS can normalize their CO₂ quickly when instructed to take deep breaths. “What we know is that the centers in the brain responsible for augmenting ventilation when CO₂ goes up are somehow blunted.”

In a study of obese mice led by Vsevolod Y. Polotsky, MD, PhD, of Johns Hopkins University, Baltimore – and highlighted by Dr. Mokhlesi as an example of important, recent research – leptin delivered intranasally alleviated hypoventilation (and upper-airway obstruction), while intraperitoneally administered leptin did not, seemingly overcoming “central leptin deficiency.” (Am J Respir Crit Care Med. 2019;199[6]:773-83).

“This proved that there is some level of resistance in this animal model ... and has potential for therapeutics in the future,” Dr. Mokhlesi said.

Understanding the role of insulin resistance in OSA is another research focus. Some data suggest that insulin resistance, which is more common in obesity, is more prevalent in populations with OSA, Dr. Patil said. Researchers have discussed a bidirectional relationship for years, but it’s likely that insulin resistance is a precursor, he said.

In a mechanistic study published in 2016, Dr. Patil and his coinvestigators found that obese individuals with insulin resistance but without frank diabetes or sleep apnea demonstrated preclinical elevations in pharyngeal collapsibility during sleep. The findings suggest that insulin resistance could play a causal role in OSA pathogenesis by “generating requisite elevations in pharyngeal collapsibility,” they wrote (Eur. Respir J. 2016;47[6]:1718-26).

More recently, Dr. Patil noted in the interview, there is increasing appreciation in academia that the type of fat may be important to predicting OSA. “Visceral fat has a completely different cytokine-secretion profile than subcutaneous fat ... it is the more metabolically active fat that may secondarily impact upper airway function though a neuroinflammatory mechanism,” he said. “That is one of the working hypotheses today.”
 

Asthma

Research has so roundly suggested that metabolic dysfunction contributes to severe, poorly controlled asthma that there’s recent and growing interest in targeting metabolic dysfunction as part of the treatment of obese asthma, said Dr. Dixon, whose own research in obesity and lung disease has focused on asthma.

Data from animal models and some epidemiologic studies have suggested that drugs used to treat type 2 diabetes mellitus, such as glucagon-like peptide receptor-1 (GLPR-1) agonists and metformin, may help control asthma. In one recent study – cited by Dr. Dixon in a 2022 review of obesity and asthma – people with obesity and asthma who were prescribed GLPR-1 agonists for diabetes had fewer asthma exacerbations compared with those who took other medications for diabetes (Semin Respir Crit Care Med. 2022 Feb 17. doi: 10.1055/s-0042-1742384).

There is also research interest in targeting the pro-inflammatory adipokine interleukin 6 (IL-6), since increased circulating levels of IL-6 correlate with asthma severity, and in addressing oxidative stress in asthma through treatment with a mitochondrially targeted antioxidant, she said. Oxidative stress is increased in the airways of people with obesity, and researchers believe it may contribute to the pathophysiology of obese asthma through effects on airway nitric oxide levels.

(Her own research work at the University of Vermont has found associations between poor asthma control and high levels of leptin, and similar associations involving low levels of adiponectin, an anti-inflammatory adipokine that has been shown to downregulate eosinophil recruitment in the airways.)

Weight loss has been shown in mostly small, single-center studies to improve asthma control, but short of weight loss, researchers are also investigating the role of poor dietary quality. Thus far, data suggest that it’s the composition of the diet, and not just its contribution to weight gain, that could be impactful, Dr. Dixon said.

More basic research questions cited by Dr. Dixon include the extent to which adipose tissue inflammation causes inflammation in the lungs. “It’s a little unclear whether all the metabolic dysfunction associated with poor asthma control is causing inflammation in the lungs,” she said, though “we’ve done some work here that shows mediators produced by the adipose tissue could be impacting production of inflammatory mediators by the airway epithelium.”

Overall, she said, “the big questions [in asthma] are, how does adipose tissue affect the airway? Is it through direct effects? Through effects on the immune system? And obesity is affected by diet and the gut microbiome – how can these be [impacting] the airway?”

Obesity “is associated with so many changes – the gut, the immune system, and metabolic dysfunction, in addition to airway mechanics,” she said, “that I no longer think, as I did when I came to this, that it’s just one thing. It’s probably all of these things together.”

In the meantime, questions about potential shared pathways for the development of obesity and asthma remain. “Obesity is a risk factor for developing asthma, but it’s also entirely possible that asthma is a risk factor for developing obesity,” she said. (Some data from pediatric populations, she noted, suggest that nonobese children with asthma are at increased risk of developing obesity.)

Also important, Dr. Dixon said, is “emerging literature in the last 5-10 years” that suggests that people with obesity are more susceptible to the effects of air pollution. Research involving inner-city schoolchildren with asthma, for instance, has shown that those with obesity had worse symptoms with air pollution exposure than did those who were not obese.
 

Pulmonary arterial hypertension

Some research has looked at adipose tissue–produced substances in PAH, but the most well-established association in obesity and PAH involves insulin resistance.

“I don’t think we’re certain as a community that obesity [in general] is the problem – it’s not itself considered a risk factor for PAH,” Anna R. Hemnes, MD, associate professor of medicine at Vanderbilt University Medical Center in Nashville, Tenn., said in an interview. She noted that it’s “hard to dissect obesity” apart.

Researchers are “more confident,” she said, “that insulin resistance – one feature of obesity [in some people] – is associated with worse outcomes in PAH.” Metabolic disease resembling insulin resistance is common in PAH and is believed to contribute to pulmonary vascular disease and right ventricular (RV) failure – the main cause of mortality in PAH – at least in part because of increased oxidative stress.

Dr. Hemnes led a mechanistic phase II clinical trial of metformin in PAH in which the drug was associated with improved RV fractional area change and reduced RV lipid deposition (J Am Heart Assoc. 2020;9[22]:e018349), and she’s now leading a National Institutes of Health–funded multicenter trial looking at the impact of metformin and an exercise intervention on 6-minute walk distance and World Health Organization functional class in PAH.

At the Rush Lung Center, in the meantime, Dr. Mokhlesi is utilizing animal models of OSA and OHS to explore the effect of hypoxia and nighttime hypercapnia on the development of PAH. “I think the jury is still out as to whether obesity itself is a major risk factor, but if so, by what mechanism?” he said. “Is it worsening [sleep-disordered breathing], which then worsens PAH?”
 

COPD

The focus in COPD has traditionally been on underweight, but the relationship between obesity and COPD has increasingly been recognized in the last 10-15 years, said Frits M. E. Franssen, MD, PhD, of CIRO, a research institute in Horn, the Netherlands, that treats COPD and other chronic lung diseases, and of the department of respiratory medicine at Maastricht University.

Researchers like Dr. Franssen are trying, for one, to understand obesity’s impact on COPD pathophysiology and to tease apart the impact of both conditions on disease severity and patient-related outcomes such as exercise capacity and exercise-related symptoms.

When Dr. Franssen’s group compared responses to weight-bearing exercise (6-min. walk test) and weight-supported exercise (cycling) in obese and normal weight COPD patients matched for age, gender, and degree of airflow limitation, the researchers found that walking capacity was significantly reduced while cycling capacity was preserved in the obese group (Respirology. 2016;21[3]:483-8).

Exercise-related symptoms (dyspnea and leg fatigue) were largely comparable between the obese and normal-weight COPD patients in both exercise modalities. However, in other studies, dyspnea ratings during cycling – at any given level of ventilation – have been lower in obese patients, indicating that “additional fat mass may have a beneficial effect on lung functioning [in non–weight-bearing exercise],” he said in an interview.

Dr. Franssen’s group also has assessed body composition in overweight and obese patients with COPD and found that a significant number have low muscle mass. These patients had worse lung function, exercise tolerance, and muscle strength compared to patients with comparable BMI and normal muscle mass (Respir Res. 2021 Mar 25. doi: 10.1186/s12931-021-01689-w).

“We’d always thought that obese patients have normal muscle mass ... but now we know it can be dramatically low,” he said. In assessing obesity and formulating any weight loss plans, “we’re now interested not only in weight but in the distribution of fat mass and fat-free mass ... and in maintaining muscle mass in patients who are [prescribed dietary interventions].”

Paradoxically, in patients with severe COPD, obesity is associated with prolonged survival, while in patients with mild to moderate COPD, obesity is associated with increased mortality risk, he noted.

The impact of adipose tissue and the chronic inflammation and metabolic disturbances that characterize obesity are currently largely unexplored, he said. Researchers have not yet studied what optimal weights may be for patients with COPD. “And we’re interested in the questions, are body weight and body composition the result of the disease, or [are they] determining the type of COPD one will get?” Dr. Franssen said.

Patients with COPD who are obese have “more of the phenotype of chronic bronchitis,” he noted, “while typical emphysema patients are normally underweight.”

The diverse effects of obesity on lung health and disease are increasingly being teased apart, with researchers honing in on the impact of metabolic dysfunction, circulating inflammatory factors produced by adipose tissue, lipid handling, and other factors – in addition to body mass index – that are associated with the obese state.

“The bird’s eye view is that obesity completely changes lung health. It’s something we’ve only recently begun to appreciate,” said Anne E.

Exercise-related symptoms (dyspnea and leg fatigue) were largely comparable between the obese and normal-weight COPD patients in both exercise modalities. However, in other studies, dyspnea ratings during cycling – at any given level of ventilation – have been lower in obese patients, indicating that “additional fat mass may have a beneficial effect on lung functioning [in non–weight-bearing exercise],” he said in an interview.

Dr. Franssen’s group also has assessed body composition in overweight and obese patients with COPD and found that a significant number have low muscle mass. These patients had worse lung function, exercise tolerance, and muscle strength compared to patients with comparable BMI and normal muscle mass (Respir Res. 2021 Mar 25. doi: 10.1186/s12931-021-01689-w).

“We’d always thought that obese patients have normal muscle mass ... but now we know it can be dramatically low,” he said. In assessing obesity and formulating any weight loss plans, “we’re now interested not only in weight but in the distribution of fat mass and fat-free mass ... and in maintaining muscle mass in patients who are [prescribed dietary interventions].”

Paradoxically, in patients with severe COPD, obesity is associated with prolonged survival, while in patients with mild to moderate COPD, obesity is associated with increased mortality risk, he noted.

The impact of adipose tissue and the chronic inflammation and metabolic disturbances that characterize obesity are currently largely unexplored, he said. Researchers have not yet studied what optimal weights may be for patients with COPD. “And we’re interested in the questions, are body weight and body composition the result of the disease, or [are they] determining the type of COPD one will get?” Dr. Franssen said.

Patients with COPD who are obese have “more of the phenotype of chronic bronchitis,” he noted, “while typical emphysema patients are normally underweight.”

The diverse effects of obesity on lung health and disease are increasingly being teased apart, with researchers honing in on the impact of metabolic dysfunction, circulating inflammatory factors produced by adipose tissue, lipid handling, and other factors – in addition to body mass index – that are associated with the obese state.

“The bird’s eye view is that obesity completely changes lung health. It’s something we’ve only recently begun to appreciate,” said Anne E. Dixon, MA, BM, BCh, director of the Vermont Lung Center at the University of Vermont, Burlington, who is focused on the research field of obesity and lung disease.

OSA and OHS

“With sleep apnea we tend to focus on anatomic considerations, but there may be relationships or interactions between obesity and neuromuscular function and neuroventilatory control,” Susheel P. Patil, MD, PhD, director of the sleep medicine program for University Hospitals and assistant professor at Case Western Reserve University, Cleveland, said in an interview.

Some studies suggest, for instance, that TNF-alpha can increase obstructive sleep apnea (OSA) susceptibility and severity through its neuroventilatory modulating properties during sleep. And the potential for additional proinflammatory cytokines produced by adipose tissue to similarly affect upper airway neuroventilatory control is an “intriguing line” of inquiry for researchers in the sleep apnea space, he said.

Leptin is of interest particularly in obesity hypoventilation syndrome (OHS), which is characterized by chronic daytime hypercapnia. Best known as a satiety hormone, leptin is produced by adipose tissue and suppresses appetite at the central nervous system level. But it has long been known that leptin also affects ventilation and the control of breathing.

When transported across the blood-brain barrier, leptin increases the hypercapnic ventilatory response, Babak Mokhlesi, MD, MSc, codirector of the Rush Lung Center and chief of pulmonary, critical care, and sleep medicine at Rush University Medical Center in Chicago, said in an interview.

Research suggests that patients with OHS may have resistance to leptin at the central nervous system level – with leptin not reaching the sites of ventilatory control. This is a “prevailing theory” and could explain why these patients “do not augment their ventilation to maintain homeostasis, normal levels of CO₂,” Dr. Mokhlesi said.

“Why some patients with severe obesity develop CO₂ retention while others do not is not fully understood,” he said, noting that patients with OHS can normalize their CO₂ quickly when instructed to take deep breaths. “What we know is that the centers in the brain responsible for augmenting ventilation when CO₂ goes up are somehow blunted.”

In a study of obese mice led by Vsevolod Y. Polotsky, MD, PhD, of Johns Hopkins University, Baltimore – and highlighted by Dr. Mokhlesi as an example of important, recent research – leptin delivered intranasally alleviated hypoventilation (and upper-airway obstruction), while intraperitoneally administered leptin did not, seemingly overcoming “central leptin deficiency.” (Am J Respir Crit Care Med. 2019;199[6]:773-83).

“This proved that there is some level of resistance in this animal model ... and has potential for therapeutics in the future,” Dr. Mokhlesi said.

Understanding the role of insulin resistance in OSA is another research focus. Some data suggest that insulin resistance, which is more common in obesity, is more prevalent in populations with OSA, Dr. Patil said. Researchers have discussed a bidirectional relationship for years, but it’s likely that insulin resistance is a precursor, he said.

In a mechanistic study published in 2016, Dr. Patil and his coinvestigators found that obese individuals with insulin resistance but without frank diabetes or sleep apnea demonstrated preclinical elevations in pharyngeal collapsibility during sleep. The findings suggest that insulin resistance could play a causal role in OSA pathogenesis by “generating requisite elevations in pharyngeal collapsibility,” they wrote (Eur. Respir J. 2016;47[6]:1718-26).

More recently, Dr. Patil noted in the interview, there is increasing appreciation in academia that the type of fat may be important to predicting OSA. “Visceral fat has a completely different cytokine-secretion profile than subcutaneous fat ... it is the more metabolically active fat that may secondarily impact upper airway function though a neuroinflammatory mechanism,” he said. “That is one of the working hypotheses today.”
 

Asthma

Research has so roundly suggested that metabolic dysfunction contributes to severe, poorly controlled asthma that there’s recent and growing interest in targeting metabolic dysfunction as part of the treatment of obese asthma, said Dr. Dixon, whose own research in obesity and lung disease has focused on asthma.

Data from animal models and some epidemiologic studies have suggested that drugs used to treat type 2 diabetes mellitus, such as glucagon-like peptide receptor-1 (GLPR-1) agonists and metformin, may help control asthma. In one recent study – cited by Dr. Dixon in a 2022 review of obesity and asthma – people with obesity and asthma who were prescribed GLPR-1 agonists for diabetes had fewer asthma exacerbations compared with those who took other medications for diabetes (Semin Respir Crit Care Med. 2022 Feb 17. doi: 10.1055/s-0042-1742384).

There is also research interest in targeting the pro-inflammatory adipokine interleukin 6 (IL-6), since increased circulating levels of IL-6 correlate with asthma severity, and in addressing oxidative stress in asthma through treatment with a mitochondrially targeted antioxidant, she said. Oxidative stress is increased in the airways of people with obesity, and researchers believe it may contribute to the pathophysiology of obese asthma through effects on airway nitric oxide levels.

(Her own research work at the University of Vermont has found associations between poor asthma control and high levels of leptin, and similar associations involving low levels of adiponectin, an anti-inflammatory adipokine that has been shown to downregulate eosinophil recruitment in the airways.)

Weight loss has been shown in mostly small, single-center studies to improve asthma control, but short of weight loss, researchers are also investigating the role of poor dietary quality. Thus far, data suggest that it’s the composition of the diet, and not just its contribution to weight gain, that could be impactful, Dr. Dixon said.

More basic research questions cited by Dr. Dixon include the extent to which adipose tissue inflammation causes inflammation in the lungs. “It’s a little unclear whether all the metabolic dysfunction associated with poor asthma control is causing inflammation in the lungs,” she said, though “we’ve done some work here that shows mediators produced by the adipose tissue could be impacting production of inflammatory mediators by the airway epithelium.”

Overall, she said, “the big questions [in asthma] are, how does adipose tissue affect the airway? Is it through direct effects? Through effects on the immune system? And obesity is affected by diet and the gut microbiome – how can these be [impacting] the airway?”

Obesity “is associated with so many changes – the gut, the immune system, and metabolic dysfunction, in addition to airway mechanics,” she said, “that I no longer think, as I did when I came to this, that it’s just one thing. It’s probably all of these things together.”

In the meantime, questions about potential shared pathways for the development of obesity and asthma remain. “Obesity is a risk factor for developing asthma, but it’s also entirely possible that asthma is a risk factor for developing obesity,” she said. (Some data from pediatric populations, she noted, suggest that nonobese children with asthma are at increased risk of developing obesity.)

Also important, Dr. Dixon said, is “emerging literature in the last 5-10 years” that suggests that people with obesity are more susceptible to the effects of air pollution. Research involving inner-city schoolchildren with asthma, for instance, has shown that those with obesity had worse symptoms with air pollution exposure than did those who were not obese.
 

Pulmonary arterial hypertension

Some research has looked at adipose tissue–produced substances in PAH, but the most well-established association in obesity and PAH involves insulin resistance.

“I don’t think we’re certain as a community that obesity [in general] is the problem – it’s not itself considered a risk factor for PAH,” Anna R. Hemnes, MD, associate professor of medicine at Vanderbilt University Medical Center in Nashville, Tenn., said in an interview. She noted that it’s “hard to dissect obesity” apart.

Researchers are “more confident,” she said, “that insulin resistance – one feature of obesity [in some people] – is associated with worse outcomes in PAH.” Metabolic disease resembling insulin resistance is common in PAH and is believed to contribute to pulmonary vascular disease and right ventricular (RV) failure – the main cause of mortality in PAH – at least in part because of increased oxidative stress.

Dr. Hemnes led a mechanistic phase II clinical trial of metformin in PAH in which the drug was associated with improved RV fractional area change and reduced RV lipid deposition (J Am Heart Assoc. 2020;9[22]:e018349), and she’s now leading a National Institutes of Health–funded multicenter trial looking at the impact of metformin and an exercise intervention on 6-minute walk distance and World Health Organization functional class in PAH.

At the Rush Lung Center, in the meantime, Dr. Mokhlesi is utilizing animal models of OSA and OHS to explore the effect of hypoxia and nighttime hypercapnia on the development of PAH. “I think the jury is still out as to whether obesity itself is a major risk factor, but if so, by what mechanism?” he said. “Is it worsening [sleep-disordered breathing], which then worsens PAH?”
 

COPD

The focus in COPD has traditionally been on underweight, but the relationship between obesity and COPD has increasingly been recognized in the last 10-15 years, said Frits M. E. Franssen, MD, PhD, of CIRO, a research institute in Horn, the Netherlands, that treats COPD and other chronic lung diseases, and of the department of respiratory medicine at Maastricht University.

Researchers like Dr. Franssen are trying, for one, to understand obesity’s impact on COPD pathophysiology and to tease apart the impact of both conditions on disease severity and patient-related outcomes such as exercise capacity and exercise-related symptoms.

When Dr. Franssen’s group compared responses to weight-bearing exercise (6-min. walk test) and weight-supported exercise (cycling) in obese and normal weight COPD patients matched for age, gender, and degree of airflow limitation, the researchers found that walking capacity was significantly reduced while cycling capacity was preserved in the obese group (Respirology. 2016;21[3]:483-8).

These patients had worse lung function, exercise tolerance, and muscle strength compared to patients with comparable BMI and normal muscle mass (Respir Res. 2021 Mar 25. doi: 10.1186/s12931-021-01689-w).

Patients with COPD who are obese have “more of the phenotype of chronic bronchitis,” he noted, “while typical emphysema patients are normally underweight.”

An intensive 1-year behavior therapy program aimed at changing a person’s response to food “cues” might help people with obesity lose a modest amount of weight, a randomized clinical trial suggests.

“Patients who are food-cue sensitive often feel out of control with their eating; they cannot resist food and/or cannot stop thinking about food,” said lead author Kerri N. Boutelle, PhD.

“Behavioral weight loss skills are not sufficient for these individuals,” so they designed this new approach, Dr. Boutelle, of the University of California, San Diego, explained in a press release.

The regulation of cues (ROC) intervention trains individuals to respond to their hunger and to resist eating highly craved foods (internal management), in contrast to behavioral weight loss programs that focus on counting calories (external management), Dr. Boutelle explained in an email.

The results of the Providing Adult Collaborative Interventions for Ideal Changes (PACIFIC) clinical trial, including follow-up out to 2 years, were published  in JAMA Network Open.

Patients in the behavioral weight loss therapy group or the combined ROC and behavioral weight loss therapy group lost more weight at 6 months than patients in the ROC group – but then they slowly regained weight (whereas patients in the ROC group did not).

At 24 months, the three groups had a similar modest weight loss, compared with a control group that did not lose weight.

“We believe these internal management strategies are more durable over time,” said Dr. Boutelle.  

However, two obesity experts, who helped develop the Canadian Adult Obesity Clinical Practice Guidelines, cautioned in emails that the intervention is very labor-intensive with less than 5% weight loss.

Four interventions

The trial was conducted at the Center for Healthy Eating and Activity Research at the University of California, San Diego, from December 2015 to December 2019.

Researchers randomized 271 adults with a mean BMI of 35 kg/m² to one of four interventions:

• Regulation of cues: Patients were not given a prescribed diet but instead were given skills to tolerate cravings and respond better to hunger or satiety cues.
• Behavioral weight loss therapy: Patients were advised to follow a balanced, calorie-deficit diet based on their weight and given related skills.
• Combined regulation of cues plus behavioral weight loss therapy.
• Control: Patients received information about nutrition and stress management plus mindfulness training and were encouraged to find social support.

Therapy was given as 26 group sessions, 90 minutes each, over 12 months, with 16 weekly sessions, four biweekly sessions, and six monthly booster sessions.

Participants were asked to take part in 150 minutes of moderate to high intensity exercise each week and aim for 10,000 steps per day. All patients except those in the control group received a pedometer.

The patients were a mean age of 46 years, 82% were women and 62% were White.

At the end of the 12-month intervention, mean BMI had dropped by –1.18 kg/m² in the ROC group and by –1.58 kg/m² and –1.56 kg/m² in the other two groups, compared with the control group, where BMI was virtually unchanged.

At 24 months follow-up, mean BMI was similar (roughly 33.5 kg/m²) in the ROC, the behavioral weight loss therapy, and the ROC plus behavioral weight loss therapy groups.

There was weight regain from 12 months in the latter two groups but not in the ROC group.
 

‘Nice study, but not practical’

“This is a nice study, but in no way is it practical,” Sean Wharton, MD, summarized.

“I think it may have difficulty finding its way into everyday practice,” said Dr. Wharton, adjunct professor at McMaster University, Hamilton, Ontario.

Also, “it does not compare ROC to pharmacotherapy,” he added, which is “quickly becoming the gold standard for obesity management. We have learned that adding intensive behavioral therapy – more visits and possibly a liquid diet as part of the weight management and some light group counseling – to pharmacotherapy does not add much.”

However, Dr. Wharton conceded that if an individual did not want, or could not take, pharmacotherapy and had access to ROC sessions, this might be a good option.

“The challenge will be offering this labor-intensive tool to 40% of Americans living with obesity,” he said.

The ROC intervention “is very different than a GP’s office that may see a patient two to three times/year max, with limited supports,” Dr. Wharton pointed out.

“It is labor-intensive, not reproducible in most places, and cannot be sustained forever. There is no evidence that the learning remains past the treatment interval. For example, 2 to 3 years later, are patients still adhering to ROC? Is weight still decreased or do they need to come to classes every month forever?”  
 

‘Modest weight loss, doubtful long-term benefits’

Similarly, Arya M. Sharma, MD, said: “While this [ROC] approach may be helpful for some individuals, given the rather modest weight loss achieved (despite considerable efforts and a cash incentive), the long-term clinical benefits remain doubtful.”

The weight loss of less than 5% over 24 months is “in the ballpark of other behavioral weight-loss interventions,” said Dr. Sharma, of the University of Edmonton, Alberta, and past scientific director of Obesity Canada.  

“I’m not convinced” about less weight regain, he added. “The difference between the groups is minimal. While this approach may well help individuals better deal with food cues, it does not change the underlying biology of weight regain.”

“This approach at best may help prevent future weight gain in susceptible individuals,” he speculated. “I would consider this more as a weight-stabilization than a weight-loss strategy.”
 

Next steps

Insurance doesn’t always cover weight loss with a mental health professional, Dr. Boutelle agreed. “However, there are eating disorder categories that also apply to many of our food-cue-sensitive patients, including binge eating,” she noted.

“We believe that ROC is an alternative model for weight loss that could be offered to patients who are interested or for whom behavioral weight loss has not been successful ... who are highly food-cue-responsive.”

The group is writing a manual about the ROC program to disseminate to other behavior therapists. They are also studying ROC in another clinical trial, Solutions for Hunger and Regulating Eating (SHARE). The ROC program is being offered at the UC San Diego Center for Healthy Eating and Activity Research, of which Dr. Boutelle is director.

The study was supported by grants from the National Institutes of Health. The researchers have reported no relevant financial relationships. Dr. Wharton has reported receiving honoraria and travel expenses and has participated in academic advisory boards for Novo Nordisk, Bausch Health, Eli Lilly, and Janssen. He is the medical director of a medical clinic specializing in weight management and diabetes. Dr. Sharma has reported receiving speakers bureau and consulting fees from Novo Nordisk, Bausch Pharmaceuticals, and AstraZeneca.

Many strategies widely considered “standard care” for managing spontaneous intracerebral hemorrhage (ICH) are not as effective as previously thought and are no longer recommended in updated guidelines from the American Heart Association/American Stroke Association (ASA).

Compression stockings, antiseizure medication, and steroid treatment are among the treatments with uncertain effectiveness, the writing group says.

The 2022 Guideline for the Management of Patients With Spontaneous ICH was published online  in Stroke. The 80-page document contains major changes and refinements to the 2015 guideline on ICH management.

“Advances have been made in an array of fields related to ICH, including the organization of regional health care systems, reversal of the negative effects of blood thinners, minimally invasive surgical procedures, and the underlying disease in small blood vessels,” Steven M. Greenberg, MD, PhD, chair of the guideline writing group with Harvard Medical School and Massachusetts General Hospital, both in Boston, said in a news release.

“We’ve updated sections across the board. There’s probably no area that went untouched with some tweaking and new evidence added that led to some changes in level of evidence or strength of a recommendation,” Dr. Greenberg added in an interview with this news organization.

“Each section comes with knowledge gaps, and it wasn’t hard to come up with knowledge gaps in every section,” Dr. Greenberg acknowledged.

Time-honored treatments no more?

Among the key updates are changes to some “time-honored” treatments that continue to be used with some “regularity” for patients with ICH, yet appear to confer either no benefit or harm, Dr. Greenberg said.

For example, for emergency or critical care treatment of ICH, prophylactic corticosteroids or continuous hyperosmolar therapy is not recommended, because it appears to have no benefit for outcome, while use of platelet transfusions outside the setting of emergency surgery or severe thrombocytopenia appears to worsen outcome, the authors say.

Use of graduated knee- or thigh-high compression stockings alone is not an effective prophylactic therapy for prevention of deep vein thrombosis (DVT). Instead, intermittent pneumatic compression (IPC) starting on the day of diagnosis is now recommended for DVT prophylaxis.

“This is an area where we still have a lot of exploration to do. It is unclear whether even specialized compression devices reduce the risks of deep vein thrombosis or improve the overall health of people with a brain bleed,” Dr. Greenberg said in the release.

The new guidance advises against use of antiseizure or antidepressant medications for ICH patients in whom there is no evidence of seizures or depression.

In clinical trials, antiseizure medication did not contribute to improvements in functionality or long-term seizure control, and the use of antidepressants increased the chance of bone fractures, the authors say.

The guideline also provides updated recommendations for acute reversal of anticoagulation after ICH. It highlights the use of protein complex concentrate for reversal of vitamin K antagonists, such as warfarin; idarucizumab for reversal of the thrombin inhibitor dabigatran; and andexanet alfa for reversal of factor Xa inhibitors, such as rivaroxaban, apixaban, and edoxaban.

For acute blood pressure lowering after mild to moderate ICH, treatment regimens that limit blood pressure variability and achieve smooth, sustained blood pressure control appear to reduce hematoma expansion and yield better functional outcome, the guideline says.

It also notes that minimally invasive approaches for hematoma evacuation, compared with medical management alone‚ have been shown to reduce mortality.

For patients with cerebellar hemorrhage, indications for immediate surgical evacuation with or without an external ventricular drain to reduce mortality now include larger volume (> 15 mL) in addition to previously recommended indications of neurologic deterioration, brainstem compression, and hydrocephalus, the authors note.

However, a “major knowledge gap is whether we can improve functional outcome with hematoma evacuation,” Dr. Greenberg said.
 

Multidisciplinary care

For rehabilitation after ICH, the guideline reinforces the importance of having a multidisciplinary team to develop a comprehensive plan for recovery.

Starting rehabilitation activities such as stretching and functional task training may be considered 24 to 48 hours following mild or moderate ICH. However, early aggressive mobilization within the first 24 hours has been linked to an increased risk of death within 14 days after an ICH, the guideline says.

Knowledge gaps include how soon it’s safe to return to work, drive, and participate in other social engagements. Recommendations on sexual activity and exercise levels that are safe after a stroke are also needed.

“People need additional help with these lifestyle changes, whether it’s moving around more, curbing their alcohol use, or eating healthier foods. This all happens after they leave the hospital, and we need to be sure we are empowering families with the information they may need to be properly supportive,” Dr. Greenberg says in the release.

The guideline points to the patient’s home caregiver as a “key and sometimes overlooked” member of the care team. It recommends psychosocial education, practical support, and training for the caregiver to improve the patient’s balance, activity level, and overall quality of life.
 

Opportunity for prevention?

The guideline also suggests there may be an opportunity to prevent ICH in some people through neuroimaging markers.

While neuroimaging is not routinely performed as a part of risk stratification for primary ICH risk, damage to small blood vessels that is associated with ICH may be evident on MRI that could signal future ICH risk, the guideline says.

“We added to the guidelines for the first time a section on mostly imaging markers of risk for having a first-ever hemorrhage,” Dr. Greenberg said in an interview.

“We don’t make any recommendations as to how to act on these markers because there is a knowledge gap. The hope is that we’ll see growth in our ability to predict first-ever hemorrhage and be able to do things to prevent first-ever hemorrhage,” he said.

“We believe the wide range of knowledge set forth in the new guideline will translate into meaningful improvements in ICH care,” Dr. Greenberg adds in the release.

The updated guideline has been endorsed by the American Association of Neurological Surgeons and Congress of Neurological Surgeons, the Society of Vascular and Interventional Neurology, and the Neurocritical Care Society. The American Academy of Neurology has affirmed the value of this statement as an educational tool for neurologists.

This research had no commercial funding. Dr. Greenberg has disclosed no relevant financial relationships. A complete list of disclosures for the guideline group is available with the original article.
