Obesity

Bariatric surgery continues to play a major role in obesity management despite the emergence of potent new weight-loss medications, according to two experts who spoke at an Endocrine Society science writers briefing.

“Bariatric surgery is safe, effective, and unfortunately underutilized for treating obesity and its complications,” said Jaime Almandoz, MD, medical director of the Weight Wellness Program at the University of Texas Southwestern Medical Center, Dallas.

Added Dr. Almandoz, who is triple board-certified in internal medicine, endocrinology, and obesity medicine, “Sometimes this gets presented in a linear fashion. ‘We’ll try lifestyle first, and if that doesn’t work, we’ll try medications, and if that doesn’t work, we’ll try surgery.’ But sometimes we might need to go straight to surgery instead of going through medications first, because it may be the most effective and evidence-based treatment for the person in the office in front of you.”

Moreover, he pointed out that currently, Medicare and many private insurers don’t cover antiobesity medications but do cover bariatric surgery.

Indeed, Srividya Kidambi, MD, professor and chief of endocrinology and molecular medicine at the Medical College of Wisconsin/Froedtert Hospital, Milwaukee, said there are certain types of patients for whom she might consider bariatric surgery first. One would be a person with a body mass index (BMI) greater than 40 kg/m² or with a BMI greater than 35 kg/m² and severe comorbidities.

Another, she said, would be young, relatively healthy people with obesity who have no comorbid conditions. “We know that if we stop the medication, the weight comes back. So, if I see a 20- to 25-year-old, am I really to commit them to lifelong therapy, or is bariatric surgery a better option in these cases? These drugs have not been around that long ... so I tend to recommend bariatric surgery in some patients.”

During the recent briefing, Dr. Almandoz summarized the evidence base for the benefits of bariatric surgery beyond weight loss, which include remission of type 2 diabetes and fatty liver disease, reduction of the risks of cardiovascular disease and cancer, and increased life expectancy.

“Everyone seems to be talking about GLP-1s for facilitating weight loss and treating obesity. ... What I want to do is provide a counterpoint to accessible therapies that are covered by more insurance plans and that may, in fact, have a better evidence base for treating obesity and its related complications,” he said in his introduction.

Bariatric surgery has been used for decades, and many centers of excellence perform it, with greatly reduced complication rates seen today than in the past. “It’s comparable to having a gallbladder surgery in terms of perioperative risk,” he noted.

Medicare and private insurers generally cover bariatric surgery for people with BMI greater than 40 kg/m2 or 35-39 kg/m² and at least one weight-related comorbidity, including type 2 diabetes, obstructive sleep apnea, hypertension, atherosclerotic disease, hyperlipidemia, and fatty liver disease.

Data suggest that weight reduction of about 3% can lead to meaningful reductions in blood glucose and triglyceride levels, but weight loss of 15% or greater is associated with reductions in cardiovascular events and type 2 diabetes remission. Lifestyle modification typically produces about 5% weight loss, compared with 20%-35% with bariatric surgery with sleeve gastrectomy or gastric bypass.

Older weight loss medications produced weight loss of 5%-10%; only the newer medications, semaglutide 2.4 mg and tirzepatide, come close to that. Weight loss with semaglutide is about 15%, while tirzepatide can produce weight loss of up to 22%. But, there are still issues with affordability, access, and lack of coverage, Dr. Almandoz noted.

One recent randomized trial of more than 400 individuals showed that bariatric surgery was more effective than lifestyle and medical therapies for treating metabolic-associated steatohepatitis without worsening of fibrosis.

Another showed that the surgery was associated with fewer major adverse liver outcomes among people who already had MASH. That same study showed a 70% reduction in cardiovascular events with bariatric surgery.

For patients with type 2 diabetes, numerous trials have demonstrated long-term remission and reduced A1c at 5 years and 10 years post surgery, along with reductions in microvascular and macrovascular complications.

Other data suggest that a shorter history of type 2 diabetes is among the factors predicting remission with bariatric surgery. “Oftentimes, both patients and providers will wait until the diabetes is quite advanced before they even have the conversation about weight loss or even bariatric surgery. This suggests that if we intervene earlier in the course of disease, when it is less severe and less advanced, we have a higher rate of causing remission in the diabetes,” Dr. Almandoz said.

The American Diabetes Association’s Standards of Care incorporate bariatric surgery as either “recommended” or “may be considered” to treat type 2 diabetes, depending on BMI level, for those who don’t achieve durable weight loss with nonsurgical methods, he noted.

A retrospective cohort study showed significant reductions in cardiovascular outcomes with bariatric surgery among people with baseline cardiovascular disease. “This is not just about bariatric surgery to cause weight loss. This is about the multitude of effects that happen when we treat obesity as a disease with highly effective therapies such as surgery,” he said.

Even cancer risk and cancer-related mortality were significantly reduced with bariatric surgery, another study found.

And in the long-term Swedish Obese Subjects Study, among people with obesity, bariatric surgery was associated with a 3-year increase in life expectancy, compared with not undergoing surgery.

However, Dr. Almandoz also pointed out that some patients may benefit from both weight-loss medication and bariatric surgery. “Once someone has undergone pharmacotherapy, there may still be a role for bariatric procedures in helping to optimize body weight and control body weight long term. And likewise for those who have undergone bariatric surgery, there’s also a role for pharmacotherapy in terms of treating insufficient weight loss or weight recurrence after bariatric surgery. ... So I think there’s clearly a role for integration of therapies.”

Dr. Almandoz serves as consultant/advisory board member for Novo Nordisk, Boehringer Ingelheim, and Eli Lilly. Dr. Kidambi is director of TOPS Center for Metabolic Research and is medical editor of TOPS Magazine, for which her institution receives an honorarium.

I cock my head at my “new” patient, Sherri, who heads into my consultation room at 8:30 on a rainy Monday morning. She looks vaguely familiar but I can’t quite place her face. “Dr. Messer,” she cries, “don’t you remember me? I was one of your very first patients 15 years ago in Westchester. You had just finished training.” Suddenly it all comes back to me.

Meeting Sherri reminded me of the lesson in humility that my mentor, Dr. Alice Levine, taught our crowded lecture hall so many years ago. Once upon a time, she prided herself on being an infinitely important doctor. One day, she met a patient with empty sella syndrome (literally missing his whole pituitary gland – MRI proven). She fully expected to swoop in to save the patient’s life by expertly replacing each absconded pituitary hormone, but to her shock and delight, an invisible little sliver of pituitary left in his brain allowed him to magically eek out completely normal hormone levels.

Sherri walked into my office so many years ago with a body mass index in the mid-40s. In laymen’s terms, she was morbidly obese. I settled in to discuss her hypertension, diabetes, high cholesterol, fatty liver, polycystic ovary syndrome, etc., but to my shock and delight, her blood pressure and blood work were completely normal. I struggled to keep a neutral face. She was there to discuss hair loss. I had just met my first patient with metabolically healthy obesity (MHO), and I was floored.

Fast-forward 15 years. Sherri sits down across the desk from me and hands me her blood work. Her formerly pristine labs are now peppered with red exclamation points and critically high lab values. Sherri had transitioned from MHO to metabolically unhealthy obesity (MUO).

Early clinical trials concluded that it was possible to have obesity but be metabolically healthy. Approximately 15% of patients living with obesity lack any of the comorbidities typically associated with this phenotype. These findings contributed to the de-emphasis on obesity as a true disease state.

In retrospect, the MHO subtype appears to be much more common in the younger and more active population and is typically quite transient. A new study published in Diabetes, Obesity and Metabolism revealed that people with MHO are 1.5 times more likely to develop diabetes vs. metabolically healthy normal-weight individuals. In addition, people living with obesity and no known metabolic complications still had a 50% higher risk for coronary artery disease. The study also showed that over 50% of people initially characterized as MHO eventually became MUO after a 16-year follow-up.

So once again, all roads lead to semaglutide (Wegovy), the most effective U.S. Food and Drug Administration–approved weight loss medication to date. The incretin class of medications not only helps patients lose 15% or more of their body weight, but it also helps reverse insulin resistance, lower the risk for heart disease, melt away fatty liver, and lower cholesterol levels and blood pressures. While an emphasis on lifestyle changes is always important, these medications are critical adjuncts to conventional therapies.

Sherri’s nearly inevitable transition from MHO to MUO speaks to the pressing need to treat patients living with obesity before the metabolic complications and increased cardiovascular risk develop. Fifteen years ago, I discussed her hair loss for 45 minutes and never mentioned the looming issue. Of course, back then there was no semaglutide or tirzepatide, which was just approved for obesity.

Sherri left our most recent visit with a prescription for Wegovy as well as appointments with a complimentary trainer and dietitian. Now that we have the tools we need, let’s commit to helping our patients achieve true metabolic health. Unlike the magical pituitary patient, metabolically healthy obesity is an illusion – and we owe it to our patients to treat it as such.

Dr. Messer is a clinical assistant professor at Mount Sinai School of Medicine, New York, and an associate professor at Hofstra University, Hempstead, N.Y. She disclosed no relevant conflicts of interest.

BOSTON – Patients with metabolic-associated steatotic liver disease (MASLD, formerly NAFLD) without cirrhosis who took daily low-dose aspirin in a double-blind randomized trial demonstrated significant reductions in liver fat content over 6 months compared with similar patients who took a placebo, study results show.

“In MASLD without cirrhosis, low-dose aspirin, 81 milligrams daily, led to decreases in liver fat and improved markers of hepatic inflammation and fibrosis,” reported Robert M. Wilechansky, MD, a transplant hepatology fellow at Massachusetts General Hospital in Boston.

“It was safe and well tolerated in this study, but we would like to see larger, longer-term clinical trials to test the efficacy of aspirin for improving histology and preventing adverse outcomes in MASLD,” he said at the annual meeting of the American Association for the Study of Liver Diseases.

“We don’t have current plans, to my knowledge, to test full-dose aspirin,” he said in an interview. “I’m encouraged by the results with low-dose aspirin, and I think that, given the risk profile, using a lower dose is preferable.”
 

Reduction in inflammation

Although promising therapies for MASLD are in development, none are currently approved by the Food and Drug Administration, prompting Dr. Wilechansky and colleagues to investigate aspirin, with its anti-inflammatory properties, as a potential treatment.

In preclinical studies, aspirin has been shown to have both anti-inflammatory and antitumor effects in the liver through inhibition of cycloxygenase-2 and platelet-derived growth factor signaling, as well as through modulation of bioactive lipids, Dr. Wilechansky said.

In observational studies, use of aspirin was associated with a reduction in the prevalence of hepatic steatosis and fibrosis progression in patients with MASLD, and there was a decrease in the incidence of hepatocellular carcinoma and liver-related mortality among patients with viral hepatitis, he noted.

As for the potential mechanism of action of aspirin for patients with MASLD, Dr. Wilechansky noted that there may be some reduction in steatosis, and “if there is a reduction in inflammation, we may see some reduction in steatohepatitis.”
 

Study details

To see whether the so-called “wonder drug” could work wonders for patients with MASLD without cirrhosis, the researchers recruited 80 adults with MASLD and randomly assigned them to receive either aspirin 81 mg once daily or placebo for 6 months.

Patients with baseline cirrhosis or other liver disease, heavy drinkers, those who had used aspirin within 6 months, or those who used other antiplatelet or anticoagulant agents were excluded, as were patients with severe renal or cardiovascular disease, active cancer, pregnancy, were breastfeeding, had thrombocytopenia, or had undergone bariatric surgery within the past 2 years.

At baseline, 36.3% of all patients had F2-F3 fibrosis, as determined by vibration-controlled transient elastography (VCTE), and of 44 patients who had previously undergone liver biopsy, 37 (84.1%) were confirmed to have steatohepatitis.

At 6 months, the absolute change in hepatic fat fraction (HFF) from baseline, the primary endpoint, was a decline of 6.1% for patients taking aspirin, compared with a 4.2% increase for patients taking placebo, which translates into a 10.3% difference in favor of aspirin (P = .009).

The relative change in HFF, a secondary endpoint, for aspirin versus placebo was –59.2% (P = .003).

In addition, the use of aspirin was associated with a relative reduction in HFF of at least 30% among 16 of the 40 patients who received it.

Aspirin was significantly better than placebo for the secondary endpoints of absolute change in hepatic fat by MRI proton-density fat fraction, with –2.9% versus placebo (P = .018), and the relative change in hepatic fat by MRI-PDFF, with a difference of –24.8% versus placebo (P = .009).

Aspirin was also associated with significantly greater reductions in liver transaminase levels and liver stiffness by VCTE.

About one-third of patients in each study arm had at least one adverse event. There was only one aspirin-related adverse event (heartburn) that led to discontinuation. There were no serious bleeding events in either arm.

“We’re going to have to consider stratifying by aspirin use now in our trials,” said Mark Hartman, MD, from Eli Lilly in Indianapolis.
 

Significant weight gain in placebo group

Mary E. McCarthy Rinella, MD, FAASLD, professor of medicine at the University of Chicago, commented that the 4% increase in liver fat in the control arm “is kind of a lot for a placebo, and I’m wondering how much that accounts for the [difference] that you saw.” Dr. Rinella served as a comoderator of the session.

Dr. Wilechansky said that there were a few outliers in the placebo group who experienced significant weight gain during the study, including one patient who gained 15 kg over 6 months.

A post hoc analysis suggested that most of the increase in hepatic fat among patients who took placebo could have been among that handful of patients, he added. When those patients were removed in an adjusted analysis, the difference between the aspirin and placebo groups was smaller but remained significant.

The trial was sponsored by Massachusetts General Hospital. Dr. Wilechansky, Dr. Rinella, and Dr. Hartman had no relevant disclosures.

BOSTON – Patients with metabolic-associated steatotic liver disease (MASLD, formerly NAFLD) without cirrhosis who took daily low-dose aspirin in a double-blind randomized trial demonstrated significant reductions in liver fat content over 6 months compared with similar patients who took a placebo, study results show.

“In MASLD without cirrhosis, low-dose aspirin, 81 milligrams daily, led to decreases in liver fat and improved markers of hepatic inflammation and fibrosis,” reported Robert M. Wilechansky, MD, a transplant hepatology fellow at Massachusetts General Hospital in Boston.

“It was safe and well tolerated in this study, but we would like to see larger, longer-term clinical trials to test the efficacy of aspirin for improving histology and preventing adverse outcomes in MASLD,” he said at the annual meeting of the American Association for the Study of Liver Diseases.

“We don’t have current plans, to my knowledge, to test full-dose aspirin,” he said in an interview. “I’m encouraged by the results with low-dose aspirin, and I think that, given the risk profile, using a lower dose is preferable.”
 

Reduction in inflammation

Although promising therapies for MASLD are in development, none are currently approved by the Food and Drug Administration, prompting Dr. Wilechansky and colleagues to investigate aspirin, with its anti-inflammatory properties, as a potential treatment.

In preclinical studies, aspirin has been shown to have both anti-inflammatory and antitumor effects in the liver through inhibition of cycloxygenase-2 and platelet-derived growth factor signaling, as well as through modulation of bioactive lipids, Dr. Wilechansky said.

In observational studies, use of aspirin was associated with a reduction in the prevalence of hepatic steatosis and fibrosis progression in patients with MASLD, and there was a decrease in the incidence of hepatocellular carcinoma and liver-related mortality among patients with viral hepatitis, he noted.

As for the potential mechanism of action of aspirin for patients with MASLD, Dr. Wilechansky noted that there may be some reduction in steatosis, and “if there is a reduction in inflammation, we may see some reduction in steatohepatitis.”
 

Study details

To see whether the so-called “wonder drug” could work wonders for patients with MASLD without cirrhosis, the researchers recruited 80 adults with MASLD and randomly assigned them to receive either aspirin 81 mg once daily or placebo for 6 months.

Patients with baseline cirrhosis or other liver disease, heavy drinkers, those who had used aspirin within 6 months, or those who used other antiplatelet or anticoagulant agents were excluded, as were patients with severe renal or cardiovascular disease, active cancer, pregnancy, were breastfeeding, had thrombocytopenia, or had undergone bariatric surgery within the past 2 years.

At baseline, 36.3% of all patients had F2-F3 fibrosis, as determined by vibration-controlled transient elastography (VCTE), and of 44 patients who had previously undergone liver biopsy, 37 (84.1%) were confirmed to have steatohepatitis.

At 6 months, the absolute change in hepatic fat fraction (HFF) from baseline, the primary endpoint, was a decline of 6.1% for patients taking aspirin, compared with a 4.2% increase for patients taking placebo, which translates into a 10.3% difference in favor of aspirin (P = .009).

The relative change in HFF, a secondary endpoint, for aspirin versus placebo was –59.2% (P = .003).

In addition, the use of aspirin was associated with a relative reduction in HFF of at least 30% among 16 of the 40 patients who received it.

Aspirin was significantly better than placebo for the secondary endpoints of absolute change in hepatic fat by MRI proton-density fat fraction, with –2.9% versus placebo (P = .018), and the relative change in hepatic fat by MRI-PDFF, with a difference of –24.8% versus placebo (P = .009).

Aspirin was also associated with significantly greater reductions in liver transaminase levels and liver stiffness by VCTE.

About one-third of patients in each study arm had at least one adverse event. There was only one aspirin-related adverse event (heartburn) that led to discontinuation. There were no serious bleeding events in either arm.

Sit less, move more. Or stand more. Or sleep more.

Replacing 30 minutes of sitting a day with equal time standing or even sleeping could improve obesity markers like body weight and waist circumference, according to a new cross-sectional study investigating the impact of movement behavior on cardiometabolic health. 

The findings suggest that, while higher-intensity activity may confer benefits sooner, adding more light activity or more standing, or even going to bed earlier, could improve heart health measures over time. 

“Our study highlights that replacing sedentary behavior with any other behavior can be beneficial,” said study author Joanna M. Blodgett, PhD, a researcher at University College London’s Institute of Sport, Exercise and Health, and department of targeted intervention.

The study builds on a large and growing body of evidence that movement behaviors impact cardiometabolic health. Increasing physical activity to 150 minutes a week has been shown to reduce the risk for cardiovascular disease by 17% and type 2 diabetes by 26%. Other studies suggest that even modest increases in physical activity can be beneficial. A prospective study published in October found that even short activity bouts of a few minutes a day may lower risks for heart attack, stroke, and early death. 

In the new study, researchers analyzed data from six studies and more than 15,000 participants, ranking behaviors according to their association with heart health. Moderate-to-vigorous activity was linked to the greatest benefit, followed by light activity, standing, sleeping, and finally – dead last on the list – sitting. 

A thigh-worn device tracked participants’ activity throughout the day, and six measures gauged heart health: body mass index (BMI), waist circumference, HDL cholesterol, total-cholesterol-to-HDL ratio, triglycerides, and glycated hemoglobin. 

Researchers modeled what would happen if people swapped various amounts of one activity for another every day for a week. Replacing just 4-13 minutes of sitting with moderate to vigorous activity improved heart health markers. 

The cardiovascular demands of regular intense activity like running, cycling, dancing, or playing sports – even in small bouts – strengthen the heart and improve blood flow throughout the body, Dr. Blodgett said. “This can lower cholesterol, blood pressure, and resting heart rate.”  

Even if adding moderate to vigorous activity is not an option, the findings suggest that people can still see benefits by replacing sitting with virtually any other activity – walking, standing, even sleeping.
 

Limitations

Because the study was observational, results can’t be used to infer causality.

“We cannot directly lean on the study results to guide prescriptions for particular exercise or lifestyle changes,” said Matthew Tomey, MD, a cardiologist with the Mount Sinai Health System, New York, who was not involved with the study. An interventional trial would be needed to confirm the findings.

The finding that sleep was better for participants than sitting is a good example. The benefits of replacing sitting with sleep were “clear” for adiposity measures like BMI and waist circumference, but negligible for blood markers such as cholesterol, triglycerides, and blood glucose, Dr. Blodgett said. 

One explanation: “The negative impact of sitting on these obesity measures is likely due to related unhealthy behaviors like snacking rather than the physiological benefits of sleep itself,” Dr. Blodgett said.

What’s more, study participants were relatively young, healthy, and active. The average age was 54, and they averaged nearly 8 hours of sleep, 10 hours of sitting, 3 hours of standing, 1.5 hours of light activity, and more than an hour of moderate to vigorous activity per day. So it’s difficult to draw conclusions about patients who don’t fit those metrics.
 

Impact on patient care

That said, the results could help tailor recommendations for patients, Dr. Blodgett said.

If a patient is struggling to exercise or is unable to exercise because of health or ability restrictions, you could help them find ways to add a lighter activity to their day, such as taking the stairs or walking briskly to catch the bus. Even swapping a regular desk for a standing one, or going to bed 30 minutes earlier, could be a more practical and effective suggestion. 

More than that: The research could be used to educate patients on the power of small changes. It shows that shifting daily habits even in small ways can make a difference, and people who are the least active stand to benefit the most. 

You can also remind patients that moderate or vigorous activity doesn’t need to happen at the gym. It could be lawn work, taking a walk, or moving heavy boxes. In fact, many activities can be “moderate” or even “vigorous” depending on the effort put into them. 

Share this rule of thumb: “An activity is classified as moderate intensity if you can talk but not sing while doing it, and an activity is generally considered vigorous intensity if you can’t say more than a few words without stopping to breathe,” Dr. Blodgett said.

The study also has implications for the potential of wearable activity trackers to monitor progress. Combining objective activity data with results from studies like this, and longer prospective studies, could help inform more helpful advice. 

“Ultimately, this research helps move us closer to more personalized guidance of how changing behaviors can improve your health,” Dr. Blodgett said.

Those who embrace lifestyle medicine are familiar with the slogan Dean Ornish, MD, likes to use: Eat well, move more, stress less, love more.

That last one, love, was the renowned physician and author’s focus at the recent American College of Lifestyle Medicine Conference in Denver. That’s because love – essentially the support, connectedness, and caring that patients feel when they join a lifestyle-change program – is “where healing occurs at the deepest level.”

Indeed, social connectedness is emerging as a vital pillar in the burgeoning field of lifestyle medicine, a specialty that uses lifestyle interventions to treat chronic conditions. About 300 lifestyle medicine programs are now integrated into residencies in medical schools across the country, up from a handful just 5 years ago, said Meagan Grega, MD, the conference chair.

“The energy and growth in American lifestyle medicine is unparalleled by anything else I see in the health care world right now,” said Dr. Grega, a family physician for 25 years in eastern Pennsylvania.

The field applies volumes of research, from the 1990s to today, demonstrating the healing effects of lifestyle changes. Dr. Ornish’s Preventive Medicine Research Institute has published research on small changes (like pomegranate juice helping blood flow in the heart) and huge ones: Coronary heart patients reversed the narrowing of arteries without lipid-lowering drugs after 1 year of lifestyle changes, including a vegetarian diet, aerobic exercise, stress management, and group support.

Ranking alongside bedrocks such as healthy diet, sleep, exercise, and stress management is positive social connection. That part, the “love more” part, often draws skepticism but is vital, said Dr. Ornish, who is sometimes referred to as the father of lifestyle medicine.

It’s “invariably the part that’s the most meaningful – that sense of connection to community that can come when you bring total strangers together,” Dr. Ornish said. “The ‘love more’ part, in many ways, is not only as important, but in some ways even more because everything really flows from that.”

Patients in a support group, who can “let down their emotional defenses and talk openly and authentically,” are much more likely to make and maintain healthy changes, Dr. Ornish said.
 

Love as medicine

The healing power of love may sound like pseudoscience, but more and more research backs the health benefits of connection and the hazards of isolation.

Mounting evidence links loneliness and isolation with a range of health issues, from mood disorders such as depression to chronic conditions such as cardiovascular disease. What’s more, data suggest that loneliness and social isolation in the United States are on the rise, and the COVID pandemic made that more clear. In May 2023, Surgeon General Vivek Murthy, MD, called loneliness, isolation, and lack of connection in the United States a “public health crisis.”

“Good relationships keep us happier and healthier,” said Robert Waldinger, MD, a psychiatrist at Massachusetts General Hospital, Boston.

Dr. Waldinger, who was not affiliated with the conference, is head of the Harvard Study of Adult Development, one of the longest studies of adult life. Beginning in 1938, the study has tracked 724 people plus more than 1,300 of their descendants and found that embracing community and close relationships helps us live longer and be happier.

In the study, the people who were most satisfied with their relationships at age 50 years were the healthiest at age 80 years. Knowing you have someone to rely on protects the brain: “Those people’s memories stay sharper longer,” Dr. Waldinger said.

He draws a distinction between connection and love. “Love is, I think, more of a feeling,” Dr. Waldinger noted. “Connection is a feeling, but it’s also an activity.”

One in five Americans say they’re lonely, he said, “and loneliness is a stressor.” People who are isolated don’t sleep as well, he added. Their health declines earlier in midlife, brain function slips sooner, and their lives are shorter.

“You don’t have anyone to complain to,” he said. If you do, “you can feel your body start to calm down.” Those without social connections may stay in a low-level “fight-or-flight mode.”

“What we think happens is that you have low levels of inflammation chronically, and those can gradually break down body systems.” Moreover, higher rates of cardiac reactivity, for instance, a racing heartbeat when upset, can lead to high blood pressure and lower immune function.

In his talk, Dr. Ornish said, “Anger is that one emotion that has consistently been shown to make heart disease worse.”

Helping people in those straits is gratifying, Dr. Ornish said. “If we can work with people as lifestyle medicine practitioners when they’re suffering, there’s an opportunity for transformation.”
 

Future

Of course, that can be easier said than done. Dr. Ornish relayed a patient’s typical reaction to a lifestyle program: “This is kind of weird stuff. Like, I get diet. But a plant-based diet, really? Meditation? Loving more? Really?”

He told the conference, “Part of our job as lifestyle medicine practitioners is to spend a little extra time with them. It doesn’t even take that much time. And to really help them understand what brings them a sense of hope and meaning and purpose.”

The results can be motivating. “Most people feel so much better so quickly,” Dr. Ornish said. “It reframes the reason for change from fear of dying to joy of living.”

Dr. Grega, for one, is optimistic for the future, citing survey results showing that 95% of medical students think that they›d be better counselors with lifestyle training. ‘They passionately want this type of thing,” she said.

It’s “invariably the part that’s the most meaningful – that sense of connection to community that can come when you bring total strangers together,” Dr. Ornish said. “The ‘love more’ part, in many ways, is not only as important, but in some ways even more because everything really flows from that.”

Patients in a support group, who can “let down their emotional defenses and talk openly and authentically,” are much more likely to make and maintain healthy changes, Dr. Ornish said.
 

Love as medicine

The healing power of love may sound like pseudoscience, but more and more research backs the health benefits of connection and the hazards of isolation.

Mounting evidence links loneliness and isolation with a range of health issues, from mood disorders such as depression to chronic conditions such as cardiovascular disease. What’s more, data suggest that loneliness and social isolation in the United States are on the rise, and the COVID pandemic made that more clear. In May 2023, Surgeon General Vivek Murthy, MD, called loneliness, isolation, and lack of connection in the United States a “public health crisis.”

“Good relationships keep us happier and healthier,” said Robert Waldinger, MD, a psychiatrist at Massachusetts General Hospital, Boston.

Dr. Waldinger, who was not affiliated with the conference, is head of the Harvard Study of Adult Development, one of the longest studies of adult life. Beginning in 1938, the study has tracked 724 people plus more than 1,300 of their descendants and found that embracing community and close relationships helps us live longer and be happier.

In the study, the people who were most satisfied with their relationships at age 50 years were the healthiest at age 80 years. Knowing you have someone to rely on protects the brain: “Those people’s memories stay sharper longer,” Dr. Waldinger said.

He draws a distinction between connection and love. “Love is, I think, more of a feeling,” Dr. Waldinger noted. “Connection is a feeling, but it’s also an activity.”

One in five Americans say they’re lonely, he said, “and loneliness is a stressor.” People who are isolated don’t sleep as well, he added. Their health declines earlier in midlife, brain function slips sooner, and their lives are shorter.

“You don’t have anyone to complain to,” he said. If you do, “you can feel your body start to calm down.” Those without social connections may stay in a low-level “fight-or-flight mode.”

“What we think happens is that you have low levels of inflammation chronically, and those can gradually break down body systems.” Moreover, higher rates of cardiac reactivity, for instance, a racing heartbeat when upset, can lead to high blood pressure and lower immune function.

In his talk, Dr. Ornish said, “Anger is that one emotion that has consistently been shown to make heart disease worse.”

Helping people in those straits is gratifying, Dr. Ornish said. “If we can work with people as lifestyle medicine practitioners when they’re suffering, there’s an opportunity for transformation.”
 

Future

Of course, that can be easier said than done. Dr. Ornish relayed a patient’s typical reaction to a lifestyle program: “This is kind of weird stuff. Like, I get diet. But a plant-based diet, really? Meditation? Loving more? Really?”

He told the conference, “Part of our job as lifestyle medicine practitioners is to spend a little extra time with them. It doesn’t even take that much time. And to really help them understand what brings them a sense of hope and meaning and purpose.”

The results can be motivating. “Most people feel so much better so quickly,” Dr. Ornish said. “It reframes the reason for change from fear of dying to joy of living.”

Dr. Grega, for one, is optimistic for the future, citing survey results showing that 95% of medical students think that they›d be better counselors with lifestyle training. ‘They passionately want this type of thing,” she said.

Those who embrace lifestyle medicine are familiar with the slogan Dean Ornish, MD, likes to use: Eat well, move more, stress less, love more.

That last one, love, was the renowned physician and author’s focus at the recent American College of Lifestyle Medicine Conference in Denver. That’s because love – essentially the support, connectedness, and caring that patients feel when they join a lifestyle-change program – is “where healing occurs at the deepest level.”

Indeed, social connectedness is emerging as a vital pillar in the burgeoning field of lifestyle medicine, a specialty that uses lifestyle interventions to treat chronic conditions. About 300 lifestyle medicine programs are now integrated into residencies in medical schools across the country, up from a handful just 5 years ago, said Meagan Grega, MD, the conference chair.

“The energy and growth in American lifestyle medicine is unparalleled by anything else I see in the health care world right now,” said Dr. Grega, a family physician for 25 years in eastern Pennsylvania.

The field applies volumes of research, from the 1990s to today, demonstrating the healing effects of lifestyle changes. Dr. Ornish’s Preventive Medicine Research Institute has published research on small changes (like pomegranate juice helping blood flow in the heart) and huge ones: Coronary heart patients reversed the narrowing of arteries without lipid-lowering drugs after 1 year of lifestyle changes, including a vegetarian diet, aerobic exercise, stress management, and group support.

Glucagon-like peptide 1 (GLP-1) agonists may help clinicians manage uncontrolled type 2 diabetes in some older patients without the need for additional glucose-controlling medications, according to a study presented Nov. 8 at the annual meeting of the Gerontological Society of America.

The study analyzed charts of 30 adults aged 65-84 years who were seen in clinic from January 2022 to February 2023 and were started on GLP-1 or GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) agonists. Participants had uncontrolled type 2 diabetes with initial A1c levels ranging from 9.6% to 12.6% and a body mass index between 27 and 48.2. The patients also received education about their conditions as well as counseling on diet and lifestyle modifications.

All participants experienced a reduction in A1c to a range of 5.8% to 7.7%, and a moderate reduction in BMI to between 23 and 39.8 within the year.

“The reduction in BMI that we saw in our patients even though they were still in the category of obesity produces a substantial benefit in the management [of type 2 diabetes],” because weight loss helps to control the condition, said Anna Pendrey, MD, assistant professor of clinical family medicine and geriatrics at Indiana University, Indianapolis, and sole author of the study.

In some cases, the addition of a GLP-1 agonist or GLP-1/GIP agonist allowed for clinicians to deprescribe other medications such as insulin and sulfonylureas, which can cause hypoglycemia in older adults, Dr. Pendrey said.

Approximately 11% of U.S. adults have type 2 diabetes, a percentage that is likely to grow given the prevalence of childhood obesity, according to the Centers for Disease Control and Prevention. Dr. Pendrey highlighted the increased incidence of newly diagnosed diabetes in individuals aged 65-79 years.

Previous studies have shown that GLP-1 agonists have the potential to aid in weight reduction, glucose control, and the prevention of major adverse cardiovascular events in these patients.

The new study is one of many post hoc analyses that mark another step forward in addressing the complex challenges associated with diabetes in older adults, according to Rodolfo Galindo, MD, director of the Comprehensive Diabetes Center at the University of Miami Health System in Florida.

“I believe this is important because unfortunately many of our older adults have both diabetes and obesity,” Dr. Galindo, who was not involved with the research, told this news organization. “You can induce remission of type 2 diabetes through weight loss that GLP-1s can cause.”

The treatment paradigm has shifted away from focusing only on lowering glucose levels as the primary means to prevent complications from diabetes, Dr. Galindo said.

Indeed, weight loss can modify diseases and prevent other complications associated with type 2 diabetes, Dr. Pendrey said.

“Weight loss and diabetes mellitus control also produces cardiovascular protection that is significant for patients with diabetes, so this group of patients in my opinion are the ones that benefit the most from GLP-1s,” she said.

Side effects of GLP-1 agonists can include nausea and vomiting, which could lead to dehydration. GLP-1s can also increase the risk for pancreatitis. For older adults, weight loss from the drug could cause sarcopenia, or loss of muscle mass, Dr. Galindo said.

“This is the reason why patients in treatment with GLP-1s have to be in close contact with their providers,” Dr. Pendrey said.

This study was independently supported. Dr. Pendrey and Dr. Galindo report no relevant conflicts.

BOSTON – With the current demand for type 2 diabetes drugs that both improve glycemic control and help patients shed large amounts of weight, liver specialists have speculated that the metabolic benefits could also extend to the liver.

Spoiler alert: they do.

In a retrospective study of patients with metabolic-associated fatty liver disease (MAFLD) and type 2 diabetes mellitus (T2DM) who received either a sodium-glucose cotransporter 2 (SGLT-2) inhibitor or glucagon-like peptide-1 (GLP-1) agonist, 87% of those who lost at least 3% of body weight within 8 weeks eventually experienced normalization of alanine aminotransferase (ALT) levels, reported Takamasa Ohki, MD, PhD, and colleagues from the department of gastroenterology at Mitsui Memorial Hospital in Tokyo.

“Body weight reduction within 8 weeks after administration of these agents was an independent factor [that] contributed to rapid improvement of ALT. Maintenance of body weight and T2DM after normalization of ALT was also very important,” they wrote in a scientific poster presented at the annual meeting of the American Association for the Study of Liver Diseases.
 

The biggest losers benefit most

Dr. Ohki and colleagues evaluated the effectiveness of SGLT-2 inhibitors and GLP-1 agonists as treatment of MAFLD for patients with T2DM.

They conducted a retrospective study of 233 patients who had both conditions and who received either of the drug classes at their institution from June 2010 through December 2021; the most recent follow-up was in December 2022. The primary endpoint of the study was normalization of ALT values.

A total of 54 patients had a 3% or greater reduction in body weight within 8 weeks of beginning treatment with their respective drugs. The researchers found that for 47 of these patients (87%), ALT values normalized; the 12-, 24-, and 36-month cumulative normalization rates were 61%, 73%, and 80%, respectively.

In contrast, among the 179 patients who did not lose weight as robustly or rapidly, 137 (76.5%) demonstrated normalization of ALT, with cumulative normalization rates of 41%, 59% and 69%, respectively (P < .01).

In multivariate analysis that controlled for age, sex, smoking, hypertension, dyslipidemia, weight reduction, and antidiabetes drug use, body weight reduction of at least 3% within 8 weeks of beginning treatment with either an SLT-2 or GLP-1 agent was associated independently with normalization of ALT, with a hazard ratio (HR) of 0.67 (P = .028).

Improvement of T2DM was an independent predictor for ALT normalization (HR, 0.64; P = .015).

Other factors contributing to ALT normalization included use of sulfonylurea (HR, 0.63; P < .01) and insulin (HR, 0.54; P < .01).

In all, 103 of the 184 patients with initial normalization of ALT values experienced a recurrence of ALT elevation during follow-up. In multivariate analysis, body weight gain and exacerbation of T2DM were independent factors for ALT reexacerbation (HR, 0.52 and 0.48, respectively; P < .01 for both comparisons).
 

Duration of effect uncertain

Philip A. Newsome, PhD, FRCPE, professor of experimental hepatology and honorary consultant hepatologist at the University of Birmingham, England, who was not involved in the study, has conducted research into the metabolic effects of SGLT-2 inhibitors and GLP-1 agonists. In an interview, he said that both drug classes are likely to have positive near-term effects on metabolic dysfunction–associated steatohepatitis (MASH, formerly NASH) through their effects on glucose control and reduction in associated comorbidities.

“The unknown question,” he added, is what will happen in the long term. “I think there are some uncertainties around what proportion of patients will essentially be downstaged or downgraded such that they don’t develop any other problem; I suspect that will be the case in very many patients. However, I suspect there will also be a large proportion that end up requiring additional therapy above and beyond weight loss,” said Dr. Newsome.

The investigators did not report a funding source for the study. Dr. Ohki and colleagues have disclosed no relevant financial relationships. Dr. Newsome has consulted on behalf of his institution with Novo Nordisk, BMS, Gilead, Pfizer, Poxel, and Intercept and has received a grant from Pharmaxis and Boehringer Ingelheim.

Final results of the SELECT trial have shown that the antiobesity drug semaglutide (Wegovy) produced a consistent reduction of around 20% versus placebo across major cardiovascular event endpoints over the approximately 3-year follow-up in patients with overweight or obesity and cardiovascular disease but not diabetes.

“This is a very exciting set of results. I think it is going to have a big impact on a large number of people,” lead investigator A. Michael Lincoff, MD, vice chair for research in the department of cardiovascular medicine at the Cleveland Clinic, said in an interview. 

“And from a scientific standpoint, these data show that we now have a new pathway or a new modifiable risk factor for cardiovascular disease that we can use in our patients who have overweight or obesity,” he added.

The trial involved 17,604 patients with a history of cardiovascular disease and a body mass index of 27 kg/m² or above (mean BMI was 33), who were randomly assigned to the glucagonlike peptide–1 (GLP-1) agonist semaglutide, given by subcutaneous injection once weekly at a gradually escalating dose up to 2.4 mg daily by week 16, or placebo. The mean baseline glycated hemoglobin level was 5.8% and 66.4% of patients met the criteria for prediabetes.

Patients lost a mean of 9.4% of body weight over the first 2 years with semaglutide versus 0.88% with placebo.

The primary cardiovascular endpoint – a composite of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke – was reduced significantly, with a hazard ratio of 0.80 (95% confidence interval, 0.72-0.90; P < .001).  

Death from cardiovascular causes, the first confirmatory secondary endpoint, showed a 15% reduction (HR, 0.85; P = .07) but this missed meeting criteria for statistical significance, and because of the hierarchical design of the trial, this meant that superiority testing was not performed for the remaining confirmatory secondary endpoints.

However, results showed reductions of around 20% for the heart failure composite endpoint and for all-cause mortality, with confidence intervals that did not cross 1.0, and directionally consistent effects were observed for all supportive secondary endpoints.

The HR for the heart failure composite endpoint was 0.82 (95% CI, 0.71-0.96), and the HR for death from any cause was 0.81 (95% CI, 0.71-0.93). Nonfatal MI was reduced by 28% (HR 0.72; 95% CI, 0.61-0.85).

The effects of semaglutide on the primary endpoint appeared to be similar across all prespecified subgroups.

Adverse events leading to discontinuation of treatment occurred in 16.6% in the semaglutide group, mostly gastrointestinal effects, and in 8.2% in the placebo group.

The trial results were presented by Dr. Lincoff at the annual scientific sessions of the American Heart Association . They were also simultaneously published online in the New England Journal of Medicine.

Dr. Lincoff explained that there is a growing pandemic of overweight and obesity worldwide with clear evidence for years that these conditions increase the risk of cardiovascular events – and yet there has been no evidence, until now, that any pharmacologic or lifestyle therapy can reduce the increased risk conferred by overweight/obesity. 

“Patients in the trial were already taking standard of care therapies for other risk factors, such as hypertension and cholesterol, so this drug is giving additional benefit,” he said.

Dr. Lincoff believes these data will lead to a large increase in use of semaglutide, which is already available for the treatment of obesity and diabetes but can be difficult to get reimbursed.

“There is a lot of difficulty getting payors to pay for this drug for weight management. But with this new data from the SELECT trial there should be more willingness – at least in the population with a history of cardiovascular disease,” he commented. In diabetes, where it is already established that there is a cardiovascular risk reduction, it is easier to get these drugs reimbursed, he noted.

On the outcome data, Dr. Lincoff said he could not explain why cardiovascular death was not significantly reduced while all-cause mortality appeared to be cut more definitively.

“The cardiovascular death curves separated, then merged, then separated again. We don’t really know what is going on there. It may be that some deaths were misclassified. This trial was conducted through the COVID era and there may have been less information available on some patients because of that.”

But he added: “The all-cause mortality is more reassuring, as it doesn’t depend on classifying cause of death. Because of the design of the trial, we can’t formally claim a reduction in all-cause mortality, but the results do suggest there is an effect on this endpoint. And all the different types of cardiovascular events were similarly reduced in a consistent way, with similar effects seen across all subgroups. That is very reassuring.”
 

‘A new era’ for patients with obesity

Outside experts in the field were also impressed with the data.

Designated discussant of the trial at the AHA meeting, Ania Jastreboff, MD, associate professor medicine (endocrinology) at Yale University, New Haven, Conn., said the SELECT trial was “a turning point in the treatment of obesity and a call to action.

“Now is the time to treat obesity to improve health outcomes in people with cardiovascular disease,” she said.

Dr. Jastreboff noted that high BMI was estimated to have accounted for 4 million deaths worldwide in 2015, two-thirds of which were caused by cardiovascular disease. And she presented data showing that U.S. individuals meeting the SELECT criteria increased from 4.3 million in 2011-12 to 6.6 million in 2017-18.

She highlighted one major limitation of the SELECT trial: it enrolled a low number of women (38%) and ethnic minorities, with only 12% of the trial population being Black.

Deepak L. Bhatt, MD, director of Mount Sinai Fuster Heart Hospital, New York, described the SELECT results as “altogether a compelling package of data.”

“These results are even better than I had expected,” Dr. Bhatt said in an interview. “There is a significant reduction in MI as I had anticipated, but additionally, there is a reduction in all-cause death. One can debate the statistics, though on a common-sense level, I think it is a real finding,” he noted.

“Given that MI, heart failure, nephropathy, and revascularization are all reduced, and even stroke is numerically lower, it makes sense that all-cause mortality would be reduced,” he said. “To me, apart from the GI side effects, this counts as a home run.”

Steve Nissen, MD, chief academic officer at the Cleveland Clinic’s Heart, Vascular and Thoracic Institute, was similarly upbeat.

“These data prove what many of us have long suspected – that losing weight can reduce cardiovascular morbidity and mortality. This is great news for patients living with obesity. The obesity epidemic is out of control,” he added. “We need to have therapies that improve cardiovascular outcomes caused by obesity and this shows that semaglutide can do that. I think this is the beginning of a whole new era for patients with obesity.”

Michelle O’Donoghue, MD, associate professor of medicine at Harvard Medical School, Boston, called the results of SELECT “both intriguing and compelling. Certainly, these findings lend further support to the use of semaglutide in a much broader secondary prevention population of individuals with obesity.”

Christie Ballantyne, MD, director of the center for cardiometabolic disease prevention at Baylor College of Medicine, Houston, described the SELECT study as “a landmark trial which will change the practice of medicine in regard to how we treat obesity.”

He compared it with the landmark 4S trial in 1994, the first study in the area of cholesterol lowering therapy to show a clear benefit in reducing cardiovascular events and total mortality, and “began a drastic change in the way that physicians approached treatment of cholesterol.”

On the more robust reduction in all-cause death, compared with cardiovascular death,

Dr. Ballantyne pointed out: “Adjudication of dead or alive is something that everyone gets right. In contrast, the cause of death is sometime difficult to ascertain. Most importantly, the benefit on total mortality also provides assurance that this therapy does not have some adverse effect on increasing noncardiovascular deaths.”
 

Gastrointestinal adverse effects

On the side effects seen with semaglutide, Dr. Lincoff reported that 10% of patients in the semaglutide group discontinued treatment because of GI side effects versus 2% in the placebo arm. He said this was “an expected issue.”

“GI effects, such as nausea, vomiting and diarrhea, are known side effects of this whole class of drugs. The dose is slowly escalated to manage these adverse effects but there will be a proportion of patients who can’t tolerate it, although the vast majority are able to continue.”

He noted that, while dose reduction was allowed, of the patients who were still on the drug at 2 years, 77% were on the full dose, and 23% were on a reduced dose.

Dr. Lincoff pointed out that there were no serious adverse events with semaglutide. “This is the largest database by far now on the drug with a long-term follow up and we didn’t see the emergence of any new safety signals, which is very reassuring.”  

Dr. Nissen said the 16% rate of patients stopping the drug because of tolerability “is not a trivial number.”

He noted that the semaglutide dose used in this study was larger than that used in diabetes.

“They did this to try to achieve more weight loss but then you get more issues with tolerability. It’s a trade-off. If patients are experiencing adverse effects, the dose can be reduced, but then you will lose some effect. All the GLP-1 agonists have GI side effects – it’s part of the way that they work.”
 

Just weight loss or other actions too?

Speculating on the mechanism behind the reduction in cardiovascular events with semaglutide, Dr. Lincoff does not think it is just weight reduction.

“The event curves start to diverge very soon after the start of the trial and yet the maximum weight loss doesn’t occur until about 65 weeks. I think something else is going on.”

In the paper, the researchers noted that GLP-1 agonists have been shown in animal studies to reduce inflammation, improve endothelial and left ventricular function, promote plaque stability, and decrease platelet aggregation. In this trial, semaglutide was associated with changes in multiple biomarkers of cardiovascular risk, including blood pressure, waist circumference, glycemic control, nephropathy, and levels of lipids and C-reactive protein.

Dr. Lincoff also pointed out that similar benefits were seen in patients with different levels of overweight, and in those who were prediabetic and those who weren’t, so benefit was not dependent on baseline BMI or glycated hemoglobin levels.

Dr. O’Donoghue agreed that other effects, as well as weight loss, could be involved. “The reduction in events with semaglutide appeared very early after initiation and far preceded the drug’s maximal effects on weight reduction. This might suggest that the drug offers other cardioprotective effects through pathways independent of weight loss. Certainly, semaglutide and the other GLP-1 agonists appear to attenuate inflammation, and the patterns of redistribution of adipose tissue may also be of interest.”

She also pointed out that the reduction in cardiovascular events appeared even earlier in this population of obese nondiabetic patients with cardiovascular disease than in prior studies of patients with diabetes. “It may suggest that there is particular benefit for this type of therapy in patients with an inflammatory milieu. I look forward to seeing further analyses to help tease apart the correlation between changes in inflammation, observed weight loss and cardiovascular benefit.”
 

Effect on clinical practice

With the majority of patients with cardiovascular disease being overweight, these results are obviously going to increase demand for semaglutide, but cost and availability are going to be an issue.

Dr. Bhatt noted that semaglutide is already very popular. “Weight loss drugs are somewhat different from other medications. I can spend 30 minutes trying to convince a patient to take a statin, but here people realize it’s going to cause weight loss and they come in asking for it even if they don’t strictly need it. I think it’s good to have cardiovascular outcome data because now at least for this population of patients, we have evidence to prescribe it.”

He agreed with Dr. Lincoff that these new data should encourage insurance companies to cover the drug, because in reducing cardiovascular events it should also improve downstream health care costs.

“It is providing clear cardiovascular and kidney benefit, so it is in the best interest to the health care system to fund this drug,” he said. “I hope insurers look at it rationally in this way, but they may also be frightened of the explosion of patients wanting this drug and now doctors wanting to prescribe it and how that would affect their shorter-term costs.”

Dr. Lincoff said it would not be easy to prioritize certain groups. “We couldn’t identify any subgroup who showed particularly more benefit than any others. But in the evolution of any therapy, there is a time period where it is in short supply and prohibitively expensive, then over time when there is some competition and pricing deals occur as more people are advocating for it, they become more available.”
 

‘A welcome treatment option’

In an editorial accompanying publication of the trial, Amit Khera, MD, University of Texas Southwestern Medical Center, Dallas, and Tiffany Powell-Wiley, MD, MPH, National Institutes of Health, Bethesda, noted that baseline risk factors such as LDL cholesterol (78 mg/dL) and systolic blood pressure (131 mm Hg) were not ideal in the semaglutide group in this trial, and they suggest that the benefits of semaglutide may be attenuated when these measures are better controlled.

But given that more than 20 million people in the United States have coronary artery disease, with the majority having overweight or obesity and only approximately 30% having concomitant diabetes, they said that, even in the context of well-controlled risk factors and very low LDL cholesterol levels, the residual risk of atherosclerotic cardiovascular disease in these persons is unacceptably high. “Thus, the SELECT trial provides a welcome treatment option that can be extended to millions of additional patients.”

However, the editorialists cautioned that semaglutide at current pricing comes with a significant cost to both patients and society, which makes this treatment inaccessible for many. 

They added that intensive lifestyle interventions and bariatric surgery remain effective but underutilized options for obesity, and that the prevention of obesity before it develops should be the primary goal.

The SELECT trial was supported by Novo Nordisk, and several coauthors are employees of the company. Dr. Lincoff is a consultant for Novo Nordisk. Dr. Bhatt and Dr. Nissen are involved in a cardiovascular outcomes trial with a new investigational weight loss drug from Lilly. Dr. Bhatt and Dr. Ballantyne are also investigators in a Novo Nordisk trial of a new anti-inflammatory drug.

Final results of the SELECT trial have shown that the antiobesity drug semaglutide (Wegovy) produced a consistent reduction of around 20% versus placebo across major cardiovascular event endpoints over the approximately 3-year follow-up in patients with overweight or obesity and cardiovascular disease but not diabetes.

And she presented data showing that U.S. individuals meeting the SELECT criteria increased from 4.3 million in 2011-12 to 6.6 million in 2017-18.

She highlighted one major limitation of the SELECT trial: it enrolled a low number of women (38%) and ethnic minorities, with only 12% of the trial population being Black.

Deepak L. Bhatt, MD, director of Mount Sinai Fuster Heart Hospital, New York, described the SELECT results as “altogether a compelling package of data.”

“These results are even better than I had expected,” Dr. Bhatt said in an interview. “There is a significant reduction in MI as I had anticipated, but additionally, there is a reduction in all-cause death. One can debate the statistics, though on a common-sense level, I think it is a real finding,” he noted.

“Given that MI, heart failure, nephropathy, and revascularization are all reduced, and even stroke is numerically lower, it makes sense that all-cause mortality would be reduced,” he said. “To me, apart from the GI side effects, this counts as a home run.”

Steve Nissen, MD, chief academic officer at the Cleveland Clinic’s Heart, Vascular and Thoracic Institute, was similarly upbeat.

“These data prove what many of us have long suspected – that losing weight can reduce cardiovascular morbidity and mortality. This is great news for patients living with obesity. The obesity epidemic is out of control,” he added. “We need to have therapies that improve cardiovascular outcomes caused by obesity and this shows that semaglutide can do that. I think this is the beginning of a whole new era for patients with obesity.”

Michelle O’Donoghue, MD, associate professor of medicine at Harvard Medical School, Boston, called the results of SELECT “both intriguing and compelling. Certainly, these findings lend further support to the use of semaglutide in a much broader secondary prevention population of individuals with obesity.”

Christie Ballantyne, MD, director of the center for cardiometabolic disease prevention at Baylor College of Medicine, Houston, described the SELECT study as “a landmark trial which will change the practice of medicine in regard to how we treat obesity.”

He compared it with the landmark 4S trial in 1994, the first study in the area of cholesterol lowering therapy to show a clear benefit in reducing cardiovascular events and total mortality, and “began a drastic change in the way that physicians approached treatment of cholesterol.”

On the more robust reduction in all-cause death, compared with cardiovascular death,

Dr. Ballantyne pointed out: “Adjudication of dead or alive is something that everyone gets right. In contrast, the cause of death is sometime difficult to ascertain. Most importantly, the benefit on total mortality also provides assurance that this therapy does not have some adverse effect on increasing noncardiovascular deaths.”
 

Gastrointestinal adverse effects

On the side effects seen with semaglutide, Dr. Lincoff reported that 10% of patients in the semaglutide group discontinued treatment because of GI side effects versus 2% in the placebo arm. He said this was “an expected issue.”

“GI effects, such as nausea, vomiting and diarrhea, are known side effects of this whole class of drugs. The dose is slowly escalated to manage these adverse effects but there will be a proportion of patients who can’t tolerate it, although the vast majority are able to continue.”

He noted that, while dose reduction was allowed, of the patients who were still on the drug at 2 years, 77% were on the full dose, and 23% were on a reduced dose.

Dr. Lincoff pointed out that there were no serious adverse events with semaglutide. “This is the largest database by far now on the drug with a long-term follow up and we didn’t see the emergence of any new safety signals, which is very reassuring.”  

Dr. Nissen said the 16% rate of patients stopping the drug because of tolerability “is not a trivial number.”

He noted that the semaglutide dose used in this study was larger than that used in diabetes.

“They did this to try to achieve more weight loss but then you get more issues with tolerability. It’s a trade-off. If patients are experiencing adverse effects, the dose can be reduced, but then you will lose some effect. All the GLP-1 agonists have GI side effects – it’s part of the way that they work.”
 

Just weight loss or other actions too?

Speculating on the mechanism behind the reduction in cardiovascular events with semaglutide, Dr. Lincoff does not think it is just weight reduction.

“The event curves start to diverge very soon after the start of the trial and yet the maximum weight loss doesn’t occur until about 65 weeks. I think something else is going on.”

In the paper, the researchers noted that GLP-1 agonists have been shown in animal studies to reduce inflammation, improve endothelial and left ventricular function, promote plaque stability, and decrease platelet aggregation. In this trial, semaglutide was associated with changes in multiple biomarkers of cardiovascular risk, including blood pressure, waist circumference, glycemic control, nephropathy, and levels of lipids and C-reactive protein.

Dr. Lincoff also pointed out that similar benefits were seen in patients with different levels of overweight, and in those who were prediabetic and those who weren’t, so benefit was not dependent on baseline BMI or glycated hemoglobin levels.

Dr. O’Donoghue agreed that other effects, as well as weight loss, could be involved. “The reduction in events with semaglutide appeared very early after initiation and far preceded the drug’s maximal effects on weight reduction. This might suggest that the drug offers other cardioprotective effects through pathways independent of weight loss. Certainly, semaglutide and the other GLP-1 agonists appear to attenuate inflammation, and the patterns of redistribution of adipose tissue may also be of interest.”

She also pointed out that the reduction in cardiovascular events appeared even earlier in this population of obese nondiabetic patients with cardiovascular disease than in prior studies of patients with diabetes. “It may suggest that there is particular benefit for this type of therapy in patients with an inflammatory milieu. I look forward to seeing further analyses to help tease apart the correlation between changes in inflammation, observed weight loss and cardiovascular benefit.”
 

Effect on clinical practice

With the majority of patients with cardiovascular disease being overweight, these results are obviously going to increase demand for semaglutide, but cost and availability are going to be an issue.

Dr. Bhatt noted that semaglutide is already very popular. “Weight loss drugs are somewhat different from other medications. I can spend 30 minutes trying to convince a patient to take a statin, but here people realize it’s going to cause weight loss and they come in asking for it even if they don’t strictly need it. I think it’s good to have cardiovascular outcome data because now at least for this population of patients, we have evidence to prescribe it.”

He agreed with Dr. Lincoff that these new data should encourage insurance companies to cover the drug, because in reducing cardiovascular events it should also improve downstream health care costs.

“It is providing clear cardiovascular and kidney benefit, so it is in the best interest to the health care system to fund this drug,” he said. “I hope insurers look at it rationally in this way, but they may also be frightened of the explosion of patients wanting this drug and now doctors wanting to prescribe it and how that would affect their shorter-term costs.”

Dr. Lincoff said it would not be easy to prioritize certain groups. “We couldn’t identify any subgroup who showed particularly more benefit than any others. But in the evolution of any therapy, there is a time period where it is in short supply and prohibitively expensive, then over time when there is some competition and pricing deals occur as more people are advocating for it, they become more available.”
 

‘A welcome treatment option’

In an editorial accompanying publication of the trial, Amit Khera, MD, University of Texas Southwestern Medical Center, Dallas, and Tiffany Powell-Wiley, MD, MPH, National Institutes of Health, Bethesda, noted that baseline risk factors such as LDL cholesterol (78 mg/dL) and systolic blood pressure (131 mm Hg) were not ideal in the semaglutide group in this trial, and they suggest that the benefits of semaglutide may be attenuated when these measures are better controlled.

But given that more than 20 million people in the United States have coronary artery disease, with the majority having overweight or obesity and only approximately 30% having concomitant diabetes, they said that, even in the context of well-controlled risk factors and very low LDL cholesterol levels, the residual risk of atherosclerotic cardiovascular disease in these persons is unacceptably high. “Thus, the SELECT trial provides a welcome treatment option that can be extended to millions of additional patients.”

However, the editorialists cautioned that semaglutide at current pricing comes with a significant cost to both patients and society, which makes this treatment inaccessible for many. 

They added that intensive lifestyle interventions and bariatric surgery remain effective but underutilized options for obesity, and that the prevention of obesity before it develops should be the primary goal.

The SELECT trial was supported by Novo Nordisk, and several coauthors are employees of the company. Dr. Lincoff is a consultant for Novo Nordisk. Dr. Bhatt and Dr. Nissen are involved in a cardiovascular outcomes trial with a new investigational weight loss drug from Lilly. Dr. Bhatt and Dr. Ballantyne are also investigators in a Novo Nordisk trial of a new anti-inflammatory drug.

BOSTON – The nomenclature may have changed, but the steady rise in the most common form of liver disease – metabolic dysfunction–associated steatotic liver disease (MASLD, formerly known as NAFLD) – is predicted to continue into the middle of this century.

That’s according to Phuc Le, PhD, MPH, and colleagues at the Cleveland Clinic. They created a mathematical model incorporating data on the growth of the U.S. population and the natural history of MASLD/NAFLD. The model projected a relative 23% increase in MASLD among U.S. adults from 2020 to 2050.

Cleveland Clinic

“Our model forecasts a substantial clinical burden of NAFLD over the next 3 decades. In the absence of effective treatments, health systems should plan for large increases in the number of liver cancer cases and the need for liver transplant,” Dr. Le said in a media briefing held on Nov. 7 prior to her presentation of the data at the annual meeting of the American Association for the Study of Liver Diseases.

The estimated worldwide prevalence of MASLD is 38%. In the United States, an estimated 27.8% of adults had MASLD as of 2020.

Dr. Le and colleagues wanted to get a clearer picture of the expected increase in the clinical burden of MASLD in the coming decades. The researchers used data from the medical literature to create an individual-level state transition model. They took into account projections of the growth of the U.S. population and the progression of MASLD and metabolic dysfunction–associated steatohepatitis (MASH, formerly NASH) through stages of fibrosis to decompensation, hepatocellular carcinoma (HCC), transplant, and liver-related death as a proportion of all-cause mortality.
 

Validated model

They validated the model by testing it against liver outcomes from 2000 through 2018 and published data on the U.S. population. The model closely matched trends in MASLD prevalence, MASH proportion, HCC and liver transplant incidences, and overall survival rates for patients with MASLD.

As noted, the model predicted a steady increase in MASLD prevalence, from 27.8% in 2020 to 34.3% by 2050, a relative increase of about 23%. The model also predicted a slight uptick in the proportion of MASH among patients with MASLD, from 20% to 21.8%.

The investigators said that the prevalence of MASLD/MASH would likely remain relatively stable among people aged 18-29 years but would increase significantly for all other age groups.

In addition, the model predicted an increase in the proportion of cirrhosis in patients with MASLD from 1.9% to 3.1%, as well as a rise in liver-related deaths from 0.4% of all deaths in 2020 to 1% by 2050.

The investigators also foresaw a rise in HCC cases, from 10,400 annually to 19,300 by 2050 and a more than twofold increase in liver transplants, from 1,700 in 2020 to 4,200 in 2050.
 

A “tsunami” of liver disease

In the question-and-answer portion of the briefing, Norah Terrault, MD, AASLD president and chief of gastroenterology and hepatology at the University of Southern California, Los Angeles, commented on the study findings and “the frightening trajectory in terms of disease burden.

“I’m thinking to myself there’s no way we’re going to be able to transplant our way out of this tsunami of disease that’s coming our way,” she said, and asked Dr. Le what policy or societal approaches might be implemented to help stem the tide.

“This is a really huge question,” Dr. Le acknowledged. The study only provides estimates of what the future burden of disease might be if there are no changes in clinical care for patients with MASLD or if the trajectory of contributing factors, such as obesity, diabetes, and other metabolic diseases, continued to increase, she cautioned.

Raising awareness of MASLD/MASH and working to improve collaboration among liver specialists and general practitioners could help to flatten the curve, she suggested.

The study was supported by a grant from the Agency for Healthcare Research and Quality. Dr. Le and Dr. Terrault have disclosed no relevant financial relations.

The current highly effective antiobesity medications approved for treating obesity (semaglutide), under review (tirzepatide), or in late-stage clinical trials “appear to lower the body’s target and defended fat mass [set point]” but do not permanently fix it at a lower point, Lee M. Kaplan, MD, PhD, explained in a lecture during the annual meeting of the Obesity Society.

It is very likely that patients with obesity will have to take these antiobesity medications “forever,” he said, “until we identify and can repair the cellular and molecular mechanisms that the body uses to regulate body fat mass throughout the life cycle and that are dysfunctional in obesity.”

“The body is able to regulate fat mass at multiple stages during development,” Dr. Kaplan, from Massachusetts General Hospital and Harvard Medical School, Boston, explained, “and when it doesn’t do it appropriately, that becomes the physiological basis of obesity.”

The loss of baby fat, as well as fat changes during puberty, menopause, aging, and, in particular, during and after pregnancy, “all occur without conscious or purposeful input,” he noted.

The body uses food intake and energy expenditure to reach and defend its intended fat mass, and there is an evolutionary benefit to doing this.

For example, people recovering from an acute illness can regain the lost fat and weight. A woman can support a pregnancy and lactation by increasing fat mass.

However, “the idea that [with antiobesity medications] we should be aiming for a fixed lower amount of fat is probably not a good idea.” Dr. Kaplan cautioned. “These medications change [the defended fat mass] to something that is more normal, rather than ‘fixing’ it.”

People need the flexibility to recover lost fat and weight after an acute illness or injury, and pregnant women need to gain an appropriate amount of body fat to support pregnancy and lactation.
 

Intermittent therapy: A practical strategy?

The long-term benefit of antiobesity medications requires continuous use, Dr. Kaplan noted. For example, in the STEP 1 trial of semaglutide in patients with obesity and without diabetes, when treatment was stopped at 68 weeks, average weight increased through 120 weeks, although it did not return to baseline levels.

Intermittent antiobesity therapy may be an effective, “very practical strategy” to maintain weight loss, which would also “address current challenges of high cost, limited drug availability, and inadequate access to care.”

“Until we have strategies for decreasing the cost of effective obesity treatment, and ensuring more equitable access to obesity care,” Dr. Kaplan said, “optimizing algorithms for the use of intermittent therapy may be an effective stopgap measure.”

Dr. Kaplan is or has recently been a paid consultant for Eli Lilly, Novo Nordisk, and multiple pharmaceutical companies developing antiobesity medications.
