TOPLINE:

Fragmented sleep — that is, increased wakefulness and reduced sleep efficiency — is a sign of metabolic dysfunction–associated steatotic liver disease (MASLD), a study using actigraphy showed.

METHODOLOGY:

• Researchers assessed sleep-wake rhythms in 35 patients with MASLD (median age, 58 years; 66% were men; 80% with metabolic syndrome) and 16 matched healthy controls (median age, 61 years; 50% were men) using data collected 24/7 via actigraphy for 4 weeks.
• Sub-analyses were conducted with MASLD comparator groups: 16 patients with MASH, 8 with MASH with cirrhosis, and 11 with non-MASH–related cirrhosis.
• All participants visited the clinic at baseline, week 2, and week 4 to undergo a clinical investigation and complete questionnaires about their sleep.
• A standardized sleep hygiene education session was conducted at week 2.

TAKEAWAY:

• Actigraphy data from patients with MASLD did not reveal significant differences in bedtime, sleep-onset latency, sleep duration, wake-up time, or time in bed compared with controls.
• However, compared with controls, those with MASLD woke 55% more often at night (8.5 vs 5.5), lay awake 113% longer after having first fallen asleep (45.4 minutes vs 21.3 minutes), and slept more often and longer during the day (decreased sleep efficiency).
• Subgroup analyses showed that actigraphy-measured sleep patterns and quality were similarly impaired in patients with MASH, MASH with cirrhosis, and non–MASH-related cirrhosis.
• Patients with MASLD self-reported their fragmented sleep as shorter sleep with a delayed onset. In sleep diaries, 32% of patients with MASLD reported sleep disturbances caused by psychological stress, compared with only 6.25% of controls and 9% of patients with cirrhosis.
• The sleep education session did not change the actigraphy measures or the sleep parameters assessed with sleep questionnaires at the end of the study.

IN PRACTICE:

“We concluded from our data that sleep fragmentation plays a role in the pathogenesis of human MASLD. Whether MASLD causes sleep disorders or vice versa remains unknown. The underlying mechanism presumably involves genetics, environmental factors, and the activation of immune responses — ultimately driven by obesity and metabolic syndrome,” said corresponding author.

SOURCE:

The study, led by Sofia Schaeffer, PhD, University of Basel, Switzerland, was published online in Frontiers in Network Physiology.

LIMITATIONS:

The study had several limitations. There was a significant difference in body mass index between patients with MASLD (median, 31) and controls (median, 23.5), representing a potential confounder that could explain the differences in sleep behavior. Undetected obstructive sleep apnea could also be a confounding factor. The small number of participants limited the interpretation and generalization of the data, especially in the MASLD subgroups.

DISCLOSURES:

This study was supported by a grant from the University of Basel. One coauthor received a research grant from the University Center for Gastrointestinal and Liver Diseases, Basel, Switzerland. Another coauthor was employed by NovoLytiX. Schaeffer and the remaining coauthors declared that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

I’m Tamaan K. Osbourne-Roberts, family medicine physician and lifestyle medicine physician, here to discuss GLP-1 receptor agonist (RA) contraindications — the skinny on when not to prescribe. 

It can be hard not to think of GLP-1 RAs like Ozempic and Mounjaro as silver bullets, long-awaited miracle drugs that we should probably be putting in the water. And it’s true they have the potential to help a lot of people. 

However, there are definitely groups of patients who should not take these drugs or should take them with caution. They include the following: 

Patients with a family history of certain cancers. Given that GLP-1 RAs can increase the risk for thyroid cancer, patients with a personal or family history of medullary thyroid cancer or multiple endocrine neoplasia type 2 should not take these drugs.

Gut motility issues. Since one of the primary mechanisms of action for these drugs is to slow down the gut, patients with gastroparesis — diabetic or otherwise — or other gut motility issues should avoid these drugs. Patients with inflammatory bowel disease also should not use GLP-1 RAs. 

Pancreatitis. These medications can increase the risk for serious pancreatitis on their own, so use in patients who have had pancreatitis already is not recommended.

Renal impairment. An eGFR [estimated glomerular filtrationrate] below threshold, typically around 30 mL/min per 1.73 m², excludes GLP-1 RAs for some patients. Be certain to check the threshold for individual medications before prescribing. 

And finally, pregnancy. These drugs generally should not be used in pregnancy, and people of childbearing age with the ability to become pregnant should use contraception while taking these medications.

GLP-1 RAs are great medications and have the potential to revolutionize obesity medicine, but like all drugs, it’s important to use them safely. Knowing when not to prescribe them is an important step in ensuring patient safety and will help ensure they are available for those who need them.

TOPLINE:

Age-standardized mortality rates for hepatocellular carcinoma (HCC) in the United States are expected to rise from 5.03 per 100,000 persons in 2022 to 6.39 per 100,000 persons by 2040. Alcohol-associated liver disease (ALD) will likely become the leading cause of HCC-related mortality by 2026, and metabolic dysfunction–associated steatotic liver disease (MASLD) is projected to become the second leading cause by 2032, a new analysis found. 

METHODOLOGY:

• HCC accounts for 75%-85% of primary liver cancers and most liver cancer deaths. Researchers have observed an upward trend in the incidence of and mortality from HCC in the past 2 decades.
• This cross-sectional study analyzed 188,280 HCC-related deaths among adults aged 25 and older to determine trends in mortality rates and project age-standardized mortality rates through 2040. Data came from the National Vital Statistics System database from 2006 to 2022.
• Researchers stratified mortality data by etiology of liver disease (ALD, hepatitis B virus, hepatitis C virus, and MASLD), age groups (25-64 or 65 and older years), sex, and race/ethnicity.
• Demographic data showed that 77.4% of deaths occurred in men, 55.6% in individuals aged 65 years or older, and 62.3% in White individuals.

TAKEAWAY:

• Overall, the age-standardized mortality rate for HCC-related deaths increased from 3.65 per 100,000 persons in 2006 to 5.03 in 2022 and was projected to increase to 6.39 per 100,000 persons by 2040.
• Sex- and age-related disparities were substantial. Men had much higher rates of HCC-related mortality than women (8.15 vs 2.33 per 100,000 persons), with a projected rate among men of 9.78 per 100,000 persons by 2040. HCC-related mortality rates for people aged 65 years or older were 10 times higher than for those aged 25-64 years (18.37 vs 1.79 per 100,000 persons) in 2022 and was projected to reach 32.81 per 100,000 persons by 2040 in the older group.
• Although hepatitis C virus–related deaths were projected to decline from 0.69 to 0.03 per 100,000 persons by 2034, ALD- and MASLD-related deaths showed increasing trends, with both projected to become the two leading causes of HCC-related mortality in the next few years.
• Racial disparities were also evident. By 2040, the American Indian/Alaska Native population showed the highest increase in projected HCC-related mortality rates, which went from 5.46 per 100,000 persons in 2006 to a project increase to 14.71 per 100,000 persons.

IN PRACTICE:

“HCC mortality was projected to continue increasing in the US, primarily due to rising rates of deaths attributable to ALD and MASLD,” the authors wrote. 

This “study highlights the importance of addressing these conditions to decrease the burden of liver disease and liver disease mortality in the future,” Emad Qayed, MD, MPH, Emory University School of Medicine, Atlanta, wrote in an accompanying editorial.

The study was led by Sikai Qiu, MM, The Second Affiliated Hospital of Xi’an Jiaotong University, Xi’an, China, and was published online in JAMA Network Open.
 

LIMITATIONS:

The National Vital Statistics System database used in this study captured only mortality data without access to detailed clinical records or individual medical histories. Researchers could not analyze socioeconomic factors or individual-level risk factors owing to data anonymization requirements. Additionally, the inclusion of the COVID-19 pandemic period could have influenced observed trends and reliability of future projections.

In preparation for a future international treaty aimed at reducing plastic pollution, the French Parliamentary Office for the Evaluation of Scientific and Technological Choices presented the conclusions of a public hearing on the impact of plastics on various aspects of human health.

Increased Global Plastic Production

Philippe Bolo, a member of the French Democratic Party and the rapporteur for the public mission on the health impacts of plastics, spoke about the latest round of treaty negotiations, held from November 25 to December 1 in South Korea, attended by leading French and global experts about the impact of plastics on human health.

The hearing highlighted a sharp increase in plastic production. “It has doubled in the last 20 years and is expected to exceed 500 million tons in 2024,” Bolo said. This is about 60 kg per person. According to projections from the Organization for Economic Co-operation and Development, on its current trajectory, plastic production will reach 750 million tons by 2040 and surpass 1 billion tons before 2050, he said.

 

Minimal Plastic Waste Recycling

Around one third (32%) of plastics are used for packaging. “Therefore, most plastic production is still intended for single-use purposes,” he said. Plastic waste follows a similar growth trajectory, with volumes expected to rise from 360 million tons in 2020 to 617 million tons by 2040 unless action is taken. Very little of this waste is recycled, even in the most countries that are most advanced in terms of collection, sorting, and processing.

In France, for example, in 2018, only 0.6 million tons of the 3.6 million tons of plastic waste produced was truly recycled. This is less than one fifth (17%). Globally, less than 10% of plastic waste is recycled. In 2020, plastic waste that ended up in the environment represented 81 million tons, or 22% of the total. “Beyond waste, this leads to pollution by microplastics and nanoplastics, resulting from their fragmentation. All environments are affected: Seas, rivers, soils, air, and even living organisms,” Bolo said.

 

Methodological Challenges

However, measuring the impact of plastics on health faces methodological difficulties due to the wide variety of composition, size, and shape of plastics. Nevertheless, the French Standardization Association (Association Française de Normalisation) has conducted work to establish a characterization standard for microplastics in water, which serves as an international reference.

“It is also very difficult to know what we are ingesting,” Bolo said. “A study conducted in 2019 estimated that the average human absorbs 5 grams of plastics per week, the equivalent of a credit card.» Since then, other studies have revised this estimate downward, but no consensus has been reached.

A recent study across 109 countries, both industrialized and developing, found significant exposure, estimated at 500 mg/d, particularly in Southeast Asian countries, where it was due mainly to seafood consumption.

A study concluded that plastic water bottles contain 240,000 particles per liter, 90% of which are nanoplastics. These nanoparticles can pass through the intestinal barrier to enter the bloodstream and reach several organs including the heart, brain, and placenta, as well as the fetus.

 

Changes to the Microbiome

Microplastics also accumulate in organs. Thus, the amount of plastic in the lungs increases with age, suggesting that particles may persist in the body without being eliminated. The health consequences of this are still poorly understood, but exposure to plastics appears to cause changes in the composition of the intestinal microbiota. Pathobionts (commensal bacteria with harmful potential) have been found in both adults and children, which could contribute to dysbiosis of the gut microbiome. Furthermore, a decrease in butyrate, a short-chain fatty acid beneficial to health, has been observed in children’s intestines.

Inhaled nanoplastics may disrupt the mucociliary clearance mechanisms of the respiratory system. The toxicity of inhaled plastic particles was demonstrated as early as the 1970s among workers in the flocking industry. Some developed lung function impairments, shortness of breath, inflammation, fibrosis, and even lung cancer. Similar symptoms have been observed in workers in the textile and polyvinyl chloride industries.

A study published recently in The New England Journal of Medicine measured the amount of microplastics collected from carotid plaque of more than 300 patients who had undergone carotid endarterectomy for asymptomatic carotid artery disease. It found a 4.53 times higher risk for the primary endpoint, a composite of myocardial infarction, stroke, and all-cause mortality, among individuals with microplastics and nanoplastics in plaque compared with those without.

 

Health Affects High

The danger of plastics is also directly linked to the chemical substances they contain. A general scientific review looked at the health impacts of three chemicals used almost exclusively in plastics: Polybromodiphenyl ethers (PBDEs), used as flame retardants in textiles or electronics; bisphenol A (BPA), used in the lining of cans and bottles; and phthalates, particularly diethylhexyl phthalate (DEHP), used to make plastics more flexible.

The review highlighted strong epidemiological evidence linking fetal exposure to PBDEs during pregnancy to low birth weight and later exposure to delayed or impaired cognitive development in children and even a loss of IQ. Statistically significant evidence of disruption of thyroid function in adults was also found.

BPA is linked to genital malformations in female newborns exposed to BPA in utero, type 2 diabetes in adults, insulin resistance, and polycystic ovary syndrome in women. BPA exposure also increases the risk for obesity and hypertension in both children and adults, as well as the risk for cardiovascular disease in adults.

Finally, the review established links between exposure to DEHP and miscarriages, genital malformations in male newborns, delayed or impaired cognitive development in children, loss of IQ, delayed psychomotor development, early puberty in young girls, and endometriosis in young women. DEHP exposure also has multiple effects on cardiometabolic health, including insulin resistance, obesity, and elevated blood pressure.

The economic costs associated with the health impacts of these three substances have been estimated at $675 billion in the United States.

Bolo said that the solution to this plastic pollution is necessarily international. “We need an ambitious and legally binding treaty to reduce plastic production,” he said. “The damage is already done; we need to act to protect human health,” he concluded. The parliamentary office has made nine recommendations to the treaty negotiators.

In preparation for a future international treaty aimed at reducing plastic pollution, the French Parliamentary Office for the Evaluation of Scientific and Technological Choices presented the conclusions of a public hearing on the impact of plastics on various aspects of human health.

Increased Global Plastic Production

Philippe Bolo, a member of the French Democratic Party and the rapporteur for the public mission on the health impacts of plastics, spoke about the latest round of treaty negotiations, held from November 25 to December 1 in South Korea, attended by leading French and global experts about the impact of plastics on human health.

The hearing highlighted a sharp increase in plastic production. “It has doubled in the last 20 years and is expected to exceed 500 million tons in 2024,” Bolo said. This is about 60 kg per person. According to projections from the Organization for Economic Co-operation and Development, on its current trajectory, plastic production will reach 750 million tons by 2040 and surpass 1 billion tons before 2050, he said.

 

Minimal Plastic Waste Recycling

Around one third (32%) of plastics are used for packaging. “Therefore, most plastic production is still intended for single-use purposes,” he said. Plastic waste follows a similar growth trajectory, with volumes expected to rise from 360 million tons in 2020 to 617 million tons by 2040 unless action is taken. Very little of this waste is recycled, even in the most countries that are most advanced in terms of collection, sorting, and processing.

In France, for example, in 2018, only 0.6 million tons of the 3.6 million tons of plastic waste produced was truly recycled. This is less than one fifth (17%). Globally, less than 10% of plastic waste is recycled. In 2020, plastic waste that ended up in the environment represented 81 million tons, or 22% of the total. “Beyond waste, this leads to pollution by microplastics and nanoplastics, resulting from their fragmentation. All environments are affected: Seas, rivers, soils, air, and even living organisms,” Bolo said.

 

Methodological Challenges

However, measuring the impact of plastics on health faces methodological difficulties due to the wide variety of composition, size, and shape of plastics. Nevertheless, the French Standardization Association (Association Française de Normalisation) has conducted work to establish a characterization standard for microplastics in water, which serves as an international reference.

“It is also very difficult to know what we are ingesting,” Bolo said. “A study conducted in 2019 estimated that the average human absorbs 5 grams of plastics per week, the equivalent of a credit card.» Since then, other studies have revised this estimate downward, but no consensus has been reached.

A recent study across 109 countries, both industrialized and developing, found significant exposure, estimated at 500 mg/d, particularly in Southeast Asian countries, where it was due mainly to seafood consumption.

A study concluded that plastic water bottles contain 240,000 particles per liter, 90% of which are nanoplastics. These nanoparticles can pass through the intestinal barrier to enter the bloodstream and reach several organs including the heart, brain, and placenta, as well as the fetus.

 

Changes to the Microbiome

Microplastics also accumulate in organs. Thus, the amount of plastic in the lungs increases with age, suggesting that particles may persist in the body without being eliminated. The health consequences of this are still poorly understood, but exposure to plastics appears to cause changes in the composition of the intestinal microbiota. Pathobionts (commensal bacteria with harmful potential) have been found in both adults and children, which could contribute to dysbiosis of the gut microbiome. Furthermore, a decrease in butyrate, a short-chain fatty acid beneficial to health, has been observed in children’s intestines.

Inhaled nanoplastics may disrupt the mucociliary clearance mechanisms of the respiratory system. The toxicity of inhaled plastic particles was demonstrated as early as the 1970s among workers in the flocking industry. Some developed lung function impairments, shortness of breath, inflammation, fibrosis, and even lung cancer. Similar symptoms have been observed in workers in the textile and polyvinyl chloride industries.

A study published recently in The New England Journal of Medicine measured the amount of microplastics collected from carotid plaque of more than 300 patients who had undergone carotid endarterectomy for asymptomatic carotid artery disease.

SAN DIEGO — In patients with metabolic dysfunction–associated steatotic liver disease (MASLD), hypertension, and cirrhosis, certain antihypertensive medications may lead to increased risks for hepatocellular carcinoma (HCC), according to new research.

In particular, the use of calcium channel blockers (CCBs), angiotensin-converting enzyme (ACE) inhibitors, and angiotensin receptor blockers (ARBs) was associated with a higher risk of developing HCC, compared with not using these medications.

About half of patients with MASLD have hypertension, and the use of antihypertensives in these patients is beneficial to reduce the risk for cardiovascular disease and complications related to MASLD, said lead author Ahmed Elhariri, MD, a research fellow at the University of Texas MD Anderson Cancer Center, Houston, who conducted the study as a research assistant in gastroenterology and hepatology at the Baylor College of Medicine, also in Houston.

However, previous studies have suggested a possible link between these medications and cancer development, “especially CCBs and breast and lung cancer,” said Elhariri, who presented the findings at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD).

 

Analyzing Potential Risks

In a case-control study, Elhariri and colleagues analyzed antihypertensive medication use among patients with MASLD-induced HCC, as defined by histology or radiology based on the Liver Imaging Reporting & Data System, and control patients with MASLD but without HCC.

Between 2020 and 2024, the research team recruited 153 newly diagnosed HCC cases with different etiologies and 170 patients with MASLD but without HCC from Baylor College of Medicine’s outpatient clinics. For this study, they selected 47 age- and sex-matched pairs, all of whom had cirrhosis. Only those with a history of hypertension were included, however. Data on risk factors of metabolic syndrome (including diabetes) and HCC were collected, along with details about medication use such as metformin and statins.

A total of 42 patients with MASLD and HCC and 39 MASLD control individuals had a history of hypertension and were treated with antihypertensive medications. The mean age was 66.5 years for the HCC group and 63.5 years for the control group, and the mean body mass index (BMI) was 31.1 for the HCC group and 31.7 for the control group.

After adjusting for age, sex, BMI, Hispanic ethnicity, and use of other medications, patients taking CCBs had an increased HCC risk (odds ratio [OR], 2.76), compared with those not taking CCBs. Patients taking ACE inhibitors or ARBs also had an increased HCC risk (OR, 2.54), compared with those not taking ACE inhibitors or ARBs.

However, there wasn’t a statistically significant difference in HCC risk among patients taking beta-blockers (OR, 0.87).

“Patients with fatty liver in the presence of metabolic syndrome, especially in the presence of cirrhosis and antihypertensives, need to have stricter surveillance for liver cancer,” Elhariri said.

“We need to carefully review blood pressure medications in patients with MASLD and cirrhosis,” he said. CCBs, ACE inhibitors, and ARBs can be replaced with beta-blockers, “which have been shown to reduce progression of cirrhosis-related complications.”

 

Considering Clinical Implications

“Although our study showed some association between the use of some commonly used antihypertensives and the risk for HCC in this high-risk population, it is based on data collected retrospectively on a small number of selected patients with advanced liver disease,” Elhariri noted.

The associations and underlying mechanisms should be studied in larger populations and prospective trials, he said. “Until we have more data with a significantly larger sample size, it’s premature to raise the concern in the general population.”

“The cardiovascular benefits of controlling blood pressure far outweigh the risk of liver cancer in patients with metabolic syndrome,” Elhariri added.

In ongoing studies, researchers are investigating ways to improve patient outcomes and reduce the negative effects of cirrhosis-associated complications among patients with MASLD and metabolic dysfunction–associated steatohepatitis (MASH), Muhammad Ali Butt, MD, a hepatology fellow at Beth Israel Lahey Hospital & Medical Center in Burlington, Massachusetts, said in an interview.

Butt, who wasn’t involved with this study, presented separate research on statins in MASH patients with cirrhosis, which indicated statistically significant decreases in portal hypertension, thrombosis, hepatorenal syndrome, hepatic encephalopathy, and mortality.

“We know patients with MASLD- and MASH-associated cirrhosis commonly have other comorbidities, including high cardiovascular risks, diabetes, and hyperlipidemia,” he said. “All of these conditions indicate patients to be on other medications such as antihypertensives or statins. It’s important to know the role these medications play, especially given the high-risk profile of these patients.”

Elhariri and Butt reported no relevant disclosures.

SAN DIEGO — In patients with metabolic dysfunction–associated steatotic liver disease (MASLD), bariatric surgery appears to carry a lower risk for mortality after 5 years than treatment with pharmacologic therapies such as glucagon-like peptide 1 (GLP-1) receptor agonists or sodium-glucose cotransporter 2 (SGLT2) inhibitors, new study results showed.

In a separate analysis of data from the same study, researchers also found that bariatric surgery alone had lower risks for major adverse cardiovascular events (MACEs) than GLP-1 or SGLT2 inhibitor use or a combination of surgery and medications.

“While weight loss medications have demonstrated notable success, especially in managing diabetes and aiding weight loss, bariatric surgery offers more significant and varied benefits for weight and metabolic health, making it a better option for some patients,” said Leith Ghani, DO, an internal medicine resident at The University of Arizona College of Medicine – Phoenix.

Ghani presented the findings about mortality at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD). His co-author and fellow internal medicine resident Qumber Ali, DO, presented the findings about MACEs.

These findings highlight “the need for personalized treatment plans, allowing the decision between surgery and medication to be customized according to each patient’s specific situation and health goals,” Ghani said. “It also emphasizes the importance of a multidisciplinary approach to patient management.”

 

Comparing Bariatric Interventions and Pharmacologic Treatments

The retrospective, multicenter study of hospital admissions data from the Banner Health system in Phoenix included more than 8600 patients who had MASLD-related diagnostic codes and metabolic criteria. Patients were divided into four groups according to the treatment they received: Bariatric surgery alone (5.8%), GLP-1 medications (39.3%), SGLT2 inhibitor medications (23.4%), or a combination of surgery and medications (31.5%).

In the mortality analysis, Ghani and colleagues looked at data for patients who died between 12 and 60 months after surgery or starting medication. They found that patients who underwent bariatric surgery had a significantly higher chance of survival at 5 years.

When compared to bariatric surgery, the adjusted hazard ratio (aHR) for GLP-1 medications was 2.99, followed by an aHR of 2.96 for SGLT2 inhibitor medications, and an aHR of 1.78 for a combination of treatments.

In the MACE analysis, Ali and colleagues looked at data for patients who were followed for 12 months or more after intervention or initiation of treatment, identifying MACE diagnostic codes for coronary artery disease, cerebrovascular disease, and congestive heart failure. They found that patients who underwent bariatric surgery alone had a significantly lower rate of MACEs.

When compared to bariatric surgery, the aHR was 1.83 for GLP-1 medications, 1.72 for SGLT2 inhibitor medications, and 1.91 for a combination of treatments.

Regarding both analyses, patients taking GLP-1 or SGLT2 inhibitor medications may face higher risks for mortality or serious heart problems due to existing metabolic disorders or heart disease, Ali said.

Future studies could look at other risk factors that make these patients more vulnerable, he added. For instance, factors related to body mass index, glucose control, other medications, different clinical settings, and race/ethnicity can contribute to different treatment responses, as could the decision to take medication or undergo surgery in the first place.

“This emphasizes the need for additional, prospective randomized clinical trial research to explore why these differences exist,” Ali said. “While progress has been made, there is still much to learn about the optimal management of patients with metabolic and cardiovascular disorders.”

 

Considering a Multidisciplinary Approach to MASLD Treatment

Ghani and Ali also called for personalized treatment plans for metabolic-related disorders such as MASLD, as well as strong communication among specialists and with patients about the benefits and risks of choosing certain medications and procedures.

“Bariatric surgery is not a universal solution, and not all patients are suitable for surgery,” Ghani said. “We also can’t say at this point that drug treatments are worse than bariatric surgery. The effectiveness of these therapies can vary greatly depending on a patient’s health, lifestyle, and preferences.”

Looking ahead, MASLD studies should investigate long-term weight loss seen with bariatric surgery and different medications, said Katherine Schwenger, PhD, RD, a scientific associate at Toronto General Hospital in Toronto, Ontario, Canada.

“GLP-1s are a hot topic right now,” said Schwenger, who wasn’t involved with the study. But “we need to look at factors such as the longevity of weight loss. It’s hard to beat the success and sustainability of bariatric surgery.”

Ghani, Ali, and Schwenger reported no relevant disclosures.

Ghani presented the findings about mortality at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD). His co-author and fellow internal medicine resident Qumber Ali, DO, presented the findings about MACEs.

These findings highlight “the need for personalized treatment plans, allowing the decision between surgery and medication to be customized according to each patient’s specific situation and health goals,” Ghani said. “It also emphasizes the importance of a multidisciplinary approach to patient management.”

 

Comparing Bariatric Interventions and Pharmacologic Treatments

The retrospective, multicenter study of hospital admissions data from the Banner Health system in Phoenix included more than 8600 patients who had MASLD-related diagnostic codes and metabolic criteria. Patients were divided into four groups according to the treatment they received: Bariatric surgery alone (5.8%), GLP-1 medications (39.3%), SGLT2 inhibitor medications (23.4%), or a combination of surgery and medications (31.5%).

In the mortality analysis, Ghani and colleagues looked at data for patients who died between 12 and 60 months after surgery or starting medication. They found that patients who underwent bariatric surgery had a significantly higher chance of survival at 5 years.

When compared to bariatric surgery, the adjusted hazard ratio (aHR) for GLP-1 medications was 2.99, followed by an aHR of 2.96 for SGLT2 inhibitor medications, and an aHR of 1.78 for a combination of treatments.

In the MACE analysis, Ali and colleagues looked at data for patients who were followed for 12 months or more after intervention or initiation of treatment, identifying MACE diagnostic codes for coronary artery disease, cerebrovascular disease, and congestive heart failure. They found that patients who underwent bariatric surgery alone had a significantly lower rate of MACEs.

When compared to bariatric surgery, the aHR was 1.83 for GLP-1 medications, 1.72 for SGLT2 inhibitor medications, and 1.91 for a combination of treatments.

Regarding both analyses, patients taking GLP-1 or SGLT2 inhibitor medications may face higher risks for mortality or serious heart problems due to existing metabolic disorders or heart disease, Ali said.

Future studies could look at other risk factors that make these patients more vulnerable, he added. For instance, factors related to body mass index, glucose control, other medications, different clinical settings, and race/ethnicity can contribute to different treatment responses, as could the decision to take medication or undergo surgery in the first place.

“This emphasizes the need for additional, prospective randomized clinical trial research to explore why these differences exist,” Ali said. “While progress has been made, there is still much to learn about the optimal management of patients with metabolic and cardiovascular disorders.”

 

Considering a Multidisciplinary Approach to MASLD Treatment

Ghani and Ali also called for personalized treatment plans for metabolic-related disorders such as MASLD, as well as strong communication among specialists and with patients about the benefits and risks of choosing certain medications and procedures.

“Bariatric surgery is not a universal solution, and not all patients are suitable for surgery,” Ghani said. “We also can’t say at this point that drug treatments are worse than bariatric surgery. The effectiveness of these therapies can vary greatly depending on a patient’s health, lifestyle, and preferences.”

Looking ahead, MASLD studies should investigate long-term weight loss seen with bariatric surgery and different medications, said Katherine Schwenger, PhD, RD, a scientific associate at Toronto General Hospital in Toronto, Ontario, Canada.

“GLP-1s are a hot topic right now,” said Schwenger, who wasn’t involved with the study. But “we need to look at factors such as the longevity of weight loss. It’s hard to beat the success and sustainability of bariatric surgery.”

Ghani, Ali, and Schwenger reported no relevant disclosures.

SAN DIEGO — In patients with metabolic dysfunction–associated steatotic liver disease (MASLD), bariatric surgery appears to carry a lower risk for mortality after 5 years than treatment with pharmacologic therapies such as glucagon-like peptide 1 (GLP-1) receptor agonists or sodium-glucose cotransporter 2 (SGLT2) inhibitors, new study results showed.

In a separate analysis of data from the same study, researchers also found that bariatric surgery alone had lower risks for major adverse cardiovascular events (MACEs) than GLP-1 or SGLT2 inhibitor use or a combination of surgery and medications.
