Clinician Reviews

As an endocrinologist, I treat many patients who have diabetes, obesity, or both. Antiobesity medications, particularly the class of glucagon-like peptide-1 receptor agonists (GLP-1 RAs), are our first support tools when nutrition and physical activity aren’t enough. With the holidays upon us, here are five tips that I often share with my patients who are on GLP-1 RAs and similar medications.

1. Be mindful of fullness cues. 

GLP-1 RAs increase satiety; they help patients feel fuller sooner within a meal and longer in between meals. This means consuming the “usual” at a holiday gathering makes them feel as if they ate too much, and often this will result in more side effects, such as nausea and reflux.

Patient tip: A good rule of thumb is to anticipate feeling full with half of your usual portion. Start with half a plate and reassess your hunger level after finishing.

2. Distinguish between hunger and “food noise.”

Ask your patients, “Do you ever find yourself eating even when you’re not hungry?” Many people eat because of emotions (eg, stress, anxiety, happiness), social situations, or cultural expectations. This type of food consumption is what scientists call “hedonic food intake” and may be driven by the “food noise” that patients describe as persistent thoughts about food in the absence of physiologic hunger. Semaglutide (Ozempic, Wegovy) has been found to reduce cravings, though other research has shown that emotional eating may blunt the effect of GLP-1 RAs.

Patient tip: Recognize when you might be seeking food for reasons other than hunger, and try a different way to address the cue (eg, chat with a friend or family member, go for a walk).

3. Be careful with alcohol.

GLP-1 RAs are being researched as potential treatments for alcohol use disorder. Many patients report less interest in alcohol and a lower tolerance to alcohol when they are taking a GLP-1 RA. Additionally, GLP-1 RAs may be a risk factor for pancreatitis, which can be caused by consuming too much alcohol.

Patient tip: The standard recommendation remains true: If drinking alcohol, limit to one to two servings per day, but also know that reduced intake or interest is normal when taking a GLP-1 RA.

4. Be aware of sickness vs side effects.

With holiday travel and the winter season, it is common for people to catch a cold or a stomach bug. Symptoms of common illnesses might include fatigue, loss of appetite, or diarrhea. These symptoms overlap with side effects of antiobesity medications like semaglutide and tirzepatide.

Patient tip: If you are experiencing constitutional or gastrointestinal symptoms due to illness, speak with your board-certified obesity medicine doctor, who may recommend a temporary medication adjustment to avoid excess side effects.

5. Stay strong against weight stigma.

The holiday season can be a stressful time, especially as patients are reconnecting with people who have not been a part of their health or weight loss journey. Unfortunately, weight bias and weight stigma remain rampant. Many people don’t understand the biology of obesity and refuse to accept the necessity of medical treatment. They may be surrounded by opinions, often louder and less informed.

Patient tip: Remember that obesity is a medical disease. Tell your nosy cousin that it’s a private health matter and that your decisions are your own.

TOPLINE:

Removing race and incorporating social determinants of health (SDOH) into the pooled cohort risk equations (PCEs) for predicting atherosclerotic cardiovascular disease (ASCVD) outcomes made no difference to patients’ risk scores.

METHODOLOGY:

• Primary prevention guidelines recommend using risk prediction algorithms to assess the 10-year ASCVD risk, with the currently recommended PCEs including race.
• Researchers evaluated the incremental value of revised risk prediction equations excluding race and introducing SDOH in 11,638 participants from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort.
• Participants were aged between 45 and 79 years, had no history of ASCVD, and were not taking statins.
• Participants were followed up to 10 years for incident ASCVD, including myocardial infarction, coronary heart disease death, and fatal and nonfatal stroke.

TAKEAWAY:

• Risk prediction equations performed similarly in race- and sex-stratified PCEs (C-statistic [95% CI])
• Black female: 0.71 (0.68-0.75); Black male: 0.68 (0.64-0.73); White female: 0.77 (0.74-0.80); White male: 0.68 (0.65-0.71)
• Race-free sex-specific PCEs yielded similar discrimination as race- and sex-stratified PCEs (C-statistic [95% CI]):
• Black female: 0.71 (0.67-0.75); Black male: 0.68 (0.63-0.72); White female: 0.76 (0.73-0.80); White male: 0.68 (0.65-0.71)
• The addition of SDOH to race-free sex-specific PCEs did not improve model performance (C-statistic [95% CI]):
• Black female: 0.72 (0.68-0.76); Black male: 0.68 (0.64-0.72); White female: 0.77 (0.74-0.80); White male: 0.68 (0.65-0.71)

IN PRACTICE:

“The major takeaway is we need to rethink the idea of race in cardiovascular risk prediction,” lead author Arnab Ghosh, MD, assistant professor of medicine at Weill Cornell Medical College and a hospitalist at New York-Presbyterian/Weill Cornell Medical Center, said in a press release.

“It’s essential for clinicians and scientists to consider how to appropriately address the health effects of race as a social construct, which has contributed to health disparities in cardiovascular outcomes,” Dr. Ghosh added.

SOURCE:

The study led by Dr. Ghosh was published online on December 6, 2023, in JAMA Cardiology with an Editor’s Note.

LIMITATIONS:

The study required informed consent for inclusion, which may have led to selection bias.

The REGARDS cohort’s SDOH may not have captured all social and socioeconomic influences on ASCVD outcomes.

DISCLOSURES:

The research was funded by the National Institute of Neurological Disorders and Stroke and the National Institute on Aging of the National Institutes of Health, Department of Health and Human Services, and others. Some authors declared receiving funding, grants, or personal fees from various sources.

This is Dr. JoAnn Manson, professor of medicine at Harvard Medical School and Brigham and Women’s Hospital. I’d like to talk about a recent report in the journal Hypertension that raises questions about whether blood pressure (BP) guidelines should be revisited and whether sex-specific thresholds and targets should be considered. Current BP guidelines are sex-agnostic.

This study was done in the large-scale nationally representative NHANES cohort. It included more than 53,000 US men and women. The average age was about 45 years, with an average duration of follow-up of 9.5 years. During that time, about 2400 cardiovascular (CVD) deaths were documented at baseline. The BP was measured three times, and the results were averaged. About 20% of the cohort were taking antihypertensive medications, and 80% were not.

Sex differences were observed in the association between BP and CVD mortality. The systolic BP associated with the lowest risk for CVD death was 110-119 mm Hg in men and 100-109 mm Hg in women. In men, however, compared with a reference category of systolic BP of 100-109 mm Hg, the risk for CVD death began to increase significantly at a systolic BP ≥ 160 mm Hg, at which point, the hazard ratio was 1.76, or 76% higher risk.

In women, the risk for CVD death began to increase significantly at a lower threshold. Compared with a reference category of systolic BP of 100-109 mm Hg, women whose systolic BP was 130-139 mm Hg had a significant 61% increase in CVD death, and among those with a systolic BP of 140-159 mm Hg, the risk was increased by 75%. With a systolic BP ≥ 160 mm Hg, CVD deaths among women were more than doubled, with a hazard ratio of 2.13.

Overall, these findings suggest sex differences, with women having an increased risk for CVD death beginning at a lower elevation of their systolic BP. For diastolic BP, both men and women showed the typical U-shaped curve and the diastolic BP associated with the lowest risk for CVD death was 70-80 mm Hg.

If these findings can be replicated with additional research and other large-scale cohort studies, and randomized trials show differences in lowering BP, then sex-specific BP guidelines could have advantages and should be seriously considered. Furthermore, some of the CVD risk scores and risk modeling should perhaps use sex-specific blood pressure thresholds.Dr. Manson received study pill donation and infrastructure support from Mars Symbioscience (for the COSMOS trial).

Patients with psoriasis being treated with biologics have a low overall risk for developing the paradoxical symptoms of eczema, with interleukin (IL)-23 inhibitors found to confer the lowest risk of the drug classes examined in a large observational analysis.

Using data from the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) database, Ali Al-Janabi, MA, from the University of Manchester (England) and associates found that 273 (1%) of approximately 25,000 drug exposures in 13,699 biologic-treated patients with psoriasis were associated with paradoxical eczema.

The incidence of paradoxical eczema was found to vary by class. The highest rate was seen for IL-17 inhibitors, at 1.22 per 100,000 person-years, and the lowest rate was seen with IL-23 inhibitors, at 0.56 per 100,000 person-years. The respective incidence rates for tumor necrosis factor (TNF) inhibitors and IL-12/IL-23 inhibitors were a respective 0.94 and 0.80 per 100,000 person-years.

“Compared with TNF inhibitors, IL-23 inhibitor exposure was associated with significantly lower risk of paradoxical eczema,” the BADBIR Study Group reported in JAMA Dermatology. Indeed, patients treated with IL-23 inhibitors were 61% less likely than were those taking TNF-inhibitors to experience a paradoxical eczema event.

“These findings remained when restricting the analysis to first-line biologic exposures and were specific to this eczema phenotype” the group said.

Cautious Interpretation

As the corresponding author for the work, Mr. Al-Janabi observed in an email that the research needs to be replicated, and the findings need to be interpreted with caution.

“As well as usual clinical variables influencing biologic selection, clinicians could consider IL-23 inhibitors in patients with previous atopic dermatitis, hay fever, or paradoxical eczema episodes, as this class was associated with the lowest risk of paradoxical eczema,” he suggested.

A prior history of atopic dermatitis (AD) and hay fever appears to be particularly relevant, as both substantially upped the chances that paradoxical eczema would occur, with hazard ratios of 12.40 and 3.78, respectively. Increasing age also increased the risk, albeit slightly (hazard ratio [HR], 1.02 per year), and there was an apparent lower risk (HR, 0.60) comparing men and women.

The BADBIR Study Group authors believe that, to the best of their knowledge, this is the first study to compare paradoxical eczema risk by biologic class. “Based on clinical experience and prevalence of eczematous reactions reported in some IL-17 inhibitor clinical trials, we suspected an association between IL-17 inhibitor exposure and paradoxical eczema,” they wrote.

“While the incidence of paradoxical eczema was numerically highest among IL-17 inhibitor exposures, it was not significantly different from the incidence among TNF inhibitor exposures.” The low overall incidence of paradoxical eczema “may be reassuring for patients and clinicians,” they added, “but it is possible that the incidence was underestimated due to underreporting or exclusion of adverse events with insufficient detail.”

Details of the Analysis, Other Findings

To explore the risk of paradoxical eczema by biologic class and identify possible risk factors, the BADBIR Study Group performed a prospective cohort study using data held within the BADBIR database between September 2007 and December 2022.

Adults over the age of 18 year or older with plaque psoriasis and who had been treated with at least one of the following biologics were eligible for inclusion: the TNF inhibitors adalimumab, certolizumab pegol, etanercept, and infliximab; the IL-17 inhibitors bimekizumab, brodalumab, ixekizumab, and secukinumab; the IL-12/23 inhibitor ustekinumab; and the IL-23 inhibitors guselkumab, risankizumab, and tildrakizumab.

Patient records and adverse event data were reviewed to determine the incidence of paradoxical eczema events, using terms such as eczema, eczematized, eczematous, atopy, atopic, and dermatitis.

Of 24,952 drug exposures analyzed, the majority (11,819) were for TNF inhibitors, followed by IL-17 inhibitors (4,776), IL-12/23 inhibitors (6,423), and finally, IL-23 inhibitors (1,934).

Mr. Al-Janabi and coauthors reported that the median time to onset of paradoxical eczema events was 294 days — approximately 9.8 months. The earliest that these events were recorded was at 120 days (4 months), and the latest at 699 days (almost 2 years).

The face and neck were the most common sites affected (26% of exposures), with other sites including the limbs (23%), the trunk (13%), and hands or feet (12%). Itching (18%), redness (7%), and dryness (4%) were the most commonly reported symptoms.

The researchers noted that 21 patients had skin biopsies taken and “all showed spongiosis or a feature of eczema, with 1 having overlapping features of psoriasis.”

In the majority (92 %) of cases, patients experienced only one eczema event. Of the 20 patients who had more than one event, just over one-fifth of repeat events occurred after receiving the same biologic as for the index event. A quarter of events occurred after a different biologic of the same class had been used, and just over half of events occurred after a different class of biologic had been given.

Strengths and Limitations

The “large sample size and inclusion of multiple lines of exposure per participant” are strengths of the study, said the researchers. “We included data for all currently available biologics, originating from more than 160 dermatology centers in the UK and Ireland.”

They added, however, that the “main limitation is the small numbers of observations within certain subgroups, such as specific biologic exposures or participants in ethnic minority groups, restricting generalizability of our findings and the interpretation of some subgroup analyses.”

Moreover, the small number of paradoxical eczema events seen may have resulted in imprecise effect estimates, they observe, noting that the number of exposures to IL-23 inhibitors was low compared with other classes.

“Future studies with more exposures and paradoxical eczema events would enable a more robust analysis of individual drugs and patient subgroups,” the authors concluded.

The study was funded by the Medical Research Council. BADBIR is coordinated by The University of Manchester, and funded by the British Association of Dermatologists (BAD). The BAD receives income from AbbVie, Almirall, Amgen, Celgene, Janssen, LEO Pharma, Lilly, Novartis, Samsung Bioepis, Sandoz Hexal AG, and UCB Pharma for providing pharmacovigilance services. This income finances a separate contract between the BAD and The University of Manchester, which coordinates BADBIR.

Patients with psoriasis being treated with biologics have a low overall risk for developing the paradoxical symptoms of eczema, with interleukin (IL)-23 inhibitors found to confer the lowest risk of the drug classes examined in a large observational analysis.

Using data from the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR) database, Ali Al-Janabi, MA, from the University of Manchester (England) and associates found that 273 (1%) of approximately 25,000 drug exposures in 13,699 biologic-treated patients with psoriasis were associated with paradoxical eczema.

The incidence of paradoxical eczema was found to vary by class. The highest rate was seen for IL-17 inhibitors, at 1.22 per 100,000 person-years, and the lowest rate was seen with IL-23 inhibitors, at 0.56 per 100,000 person-years. The respective incidence rates for tumor necrosis factor (TNF) inhibitors and IL-12/IL-23 inhibitors were a respective 0.94 and 0.80 per 100,000 person-years.

“Compared with TNF inhibitors, IL-23 inhibitor exposure was associated with significantly lower risk of paradoxical eczema,” the BADBIR Study Group reported in JAMA Dermatology. Indeed, patients treated with IL-23 inhibitors were 61% less likely than were those taking TNF-inhibitors to experience a paradoxical eczema event.

“These findings remained when restricting the analysis to first-line biologic exposures and were specific to this eczema phenotype” the group said.

Cautious Interpretation

As the corresponding author for the work, Mr. Al-Janabi observed in an email that the research needs to be replicated, and the findings need to be interpreted with caution.

“As well as usual clinical variables influencing biologic selection, clinicians could consider IL-23 inhibitors in patients with previous atopic dermatitis, hay fever, or paradoxical eczema episodes, as this class was associated with the lowest risk of paradoxical eczema,” he suggested.

A prior history of atopic dermatitis (AD) and hay fever appears to be particularly relevant, as both substantially upped the chances that paradoxical eczema would occur, with hazard ratios of 12.40 and 3.78, respectively. Increasing age also increased the risk, albeit slightly (hazard ratio [HR], 1.02 per year), and there was an apparent lower risk (HR, 0.60) comparing men and women.

The BADBIR Study Group authors believe that, to the best of their knowledge, this is the first study to compare paradoxical eczema risk by biologic class. “Based on clinical experience and prevalence of eczematous reactions reported in some IL-17 inhibitor clinical trials, we suspected an association between IL-17 inhibitor exposure and paradoxical eczema,” they wrote.

“While the incidence of paradoxical eczema was numerically highest among IL-17 inhibitor exposures, it was not significantly different from the incidence among TNF inhibitor exposures.” The low overall incidence of paradoxical eczema “may be reassuring for patients and clinicians,” they added, “but it is possible that the incidence was underestimated due to underreporting or exclusion of adverse events with insufficient detail.”

Details of the Analysis, Other Findings

To explore the risk of paradoxical eczema by biologic class and identify possible risk factors, the BADBIR Study Group performed a prospective cohort study using data held within the BADBIR database between September 2007 and December 2022.

Adults over the age of 18 year or older with plaque psoriasis and who had been treated with at least one of the following biologics were eligible for inclusion: the TNF inhibitors adalimumab, certolizumab pegol, etanercept, and infliximab; the IL-17 inhibitors bimekizumab, brodalumab, ixekizumab, and secukinumab; the IL-12/23 inhibitor ustekinumab; and the IL-23 inhibitors guselkumab, risankizumab, and tildrakizumab.

Patient records and adverse event data were reviewed to determine the incidence of paradoxical eczema events, using terms such as eczema, eczematized, eczematous, atopy, atopic, and dermatitis.

Of 24,952 drug exposures analyzed, the majority (11,819) were for TNF inhibitors, followed by IL-17 inhibitors (4,776), IL-12/23 inhibitors (6,423), and finally, IL-23 inhibitors (1,934).

Mr. Al-Janabi and coauthors reported that the median time to onset of paradoxical eczema events was 294 days — approximately 9.8 months. The earliest that these events were recorded was at 120 days (4 months), and the latest at 699 days (almost 2 years).

The face and neck were the most common sites affected (26% of exposures), with other sites including the limbs (23%), the trunk (13%), and hands or feet (12%). Itching (18%), redness (7%), and dryness (4%) were the most commonly reported symptoms.

The researchers noted that 21 patients had skin biopsies taken and “all showed spongiosis or a feature of eczema, with 1 having overlapping features of psoriasis.”

In the majority (92 %) of cases, patients experienced only one eczema event. Of the 20 patients who had more than one event, just over one-fifth of repeat events occurred after receiving the same biologic as for the index event.

Adults who used thiazide diuretics for hypertension were more likely than were those who used nonthiazide agents to develop hyponatremia within 2 years of starting treatment, a new study of more than 180,000 people has found.

Although thiazide diuretics generally are well-tolerated in the routine treatment of uncomplicated hypertension, severe adverse effects are possible, and their frequency has not been examined, according to Niklas Worm Andersson, MD, of Statens Serum Institut, in Copenhagen, Denmark, and his colleagues.

“Thiazide diuretics are commonly used drugs for the treatment of uncomplicated hypertension, and hyponatremia is a known potential side effect to thiazide treatment, but the frequency of this adverse event is inconsistently reported across drug labels,” Dr. Andersson told this news organization.

Product labels for thiazide diuretics list hyponatremia as a potential adverse event that can occur rarely (defined as a range from less than 1 in 10,000 to less than 1 in 100 individuals), but the extent of the burden is unclear given the wide range of symptoms of the condition, the researchers write. 

In a study published in Annals of Internal Medicine, Dr. Andersson and his colleagues reviewed data from population-based registries in Denmark of adults aged 40 years or older with uncomplicated hypertension, no recent prescriptions for antihypertensives, and no previous history of hyponatremia. They emulated two target trials. One trial compared the incidence of hyponatremia in new users of bendroflumethiazide (BFZ) vs a calcium-channel blocker (CCB). The other emulation compared the incidence of hyponatremia in new users of hydrochlorothiazide (HCTZ) plus a renin-angiotensin system (RAS) inhibitor vs a RAS inhibitor without HCTZ. 

The primary outcome was hyponatremia, defined as blood sodium < 130 mmol/L, within 2 years of starting treatment. 

The 2-year incidence of hyponatremia for the two thiazide diuretics was 3.83% for BFZ and 3.51% for HCTZ-RAS inhibitor. The risk difference in the incidence of hyponatremia was 1.35% for BFZ vs CCB and 1.38% for HCTZ-RAS inhibitor vs RAS inhibitor, the researchers reported. 

The study population included 37,786 new users of BFZ who were compared with 44,963 new users of CCBs as well as 11,943 new users of HCTZ-RAS inhibitors who were compared with 85,784 new users of RAS inhibitors only. 

Overall, older age and a greater number of comorbidities increased the cumulative hyponatremia in new users of thiazide-based hypertensives. The risk differences among individuals aged 80 years or older were 4.80% in the BFZ vs CCB study and 5.52% in the HCTZ-RAS inhibitor vs RAS inhibitor study. Among participants with three or more comorbidities, the risk differences in the two studies were 5.24% and 2.91%, respectively, Dr. Andersson’s group found.

The findings were limited by several factors, mainly the potential for confounding on the basis of the assumption that filled prescriptions equaled drug use, the researchers noted. Other limitations included the focus on new users and a Danish population only, which might limit generalizability, and a lack of data on blood pressure measures.

However, the results suggest a greater risk for hyponatremia with thiazide diuretics than what the drug labels indicate, especially early in treatment, the researchers concluded.

 

Data Reinforce Need for Vigilance in the Clinic

“Our findings highlight the continued need for clinical awareness and monitoring of this adverse drug reaction; particularly during the first months of treatment, in persons who are older or who have comorbidities,” Dr. Andersson told this news organization. “Further mapping of potential subpopulations at risk in terms of specific comorbidities is important to improve the prevention of this adverse event.”

“The thiazide diuretics have been recommended as first-line therapy for hypertension, and it was important to evaluate the potential development of hyponatremia, especially in the older patients given the potentially serious health effects caused by hyponatremia,” said Noel Deep, MD, a general internist in private practice in Antigo, Wisconsin. Dr. Deep, who was not involved in the study, also serves as chief medical officer and a staff physician at Aspirus Langlade Hospital in Antigo. 

The current study findings were not surprising, Dr. Deep added. “I have seen this occur in my patients, especially in the older female patients,” he said. “The results reinforce my practice of monitoring the electrolytes and renal function in 1-2 weeks after starting a thiazide diuretic, and then at regular intervals.”

In practice, clinicians should be aware of the potential development of hyponatremia and monitor and address the electrolyte abnormalities, Dr. Deep said. “While thiazide and thiazide-like diuretics are an important component of our treatment options for patients with hypertension and other conditions, we should also ensure that we are cognizant of and address the potential side effects or electrolyte imbalances caused by the medications.” 

The study was funded by the Independent Research Fund Denmark, Helsefonden, Dagmar Marshalls Fond, Gangstedfonden, A.P. Møller and Chastine Mc-Kinney Møller Foundation, Brødrene Hartmanns Fond, and Snedkermester Sophus Jacobsen og hustru Astrid Jacobsens Fond.

Emergency department (ED) visits by adults with diabetes increased by more than 25% since 2012, with the highest rates among Blacks and those aged over 65 years, a new data brief from the Centers for Disease Control and Prevention’s National Center for Health Statistics shows.

In 2021, diabetes was the eighth leading cause of death in the United States, according to the brief, published online on December 19, 2023. Its frequency is increasing in young people, and increasing age is a risk factor for hospitalization.

The latest data show that in 2020-2021, the overall annual ED visit rate was 72.2 visits per 1000 adults with diabetes, with no significant difference in terms of sex (75.1 visits per 1000 women vs 69.1 visits per 1000 men). By race/ethnicity, Blacks had the highest rates, at 135.5 visits per 1000 adults, followed by Whites (69.9) and Hispanics (52.3). The rates increased with age for both women and men, and among the three race/ethnic groups.

Comorbidities Count

The most ED visits were made by patients with diabetes and two to four other chronic conditions (541.4 visits per 1000 visits). Rates for patients without other chronic conditions were the lowest (90.2).

Among individuals with diabetes aged 18-44 years, ED visit rates were the highest for those with two to four other chronic conditions (402.0) and lowest among those with five or more other conditions (93.8).

Among patients aged 45-64 years, ED visit rates were the highest for those with two to four other chronic conditions (526.4) and lowest for those without other conditions (87.7). In the 65 years and older group, rates were the highest for individuals with two to four other chronic conditions (605.2), followed by five or more conditions (217.7), one other condition (140.6), and no other conditions (36.5).

Notably, the ED visit rates for those with two to four or five or more other chronic conditions increased with age, whereas visits for those with no other chronic conditions or one other condition decreased with age.

Decade-Long Trend

ED visit rates among adults with diabetes increased throughout the past decade, from 48.6 visits per 1000 adults in 2012 to 74.9 per 1000 adults in 2021. Rates for those aged 65 and older were higher than all other age groups, increasing from 113.4 to 156.8. Increases were also seen among those aged 45-64 years (53.1 in 2012 to 89.2 in 2021) and 18-44 (20.9 in 2012 to 26.4 in 2016, then plateauing from 2016-2021).

Data are based on a sample of 4051 ED visits, representing about 18,238,000 average annual visits made by adults with diabetes to nonfederal, general, and short-stay hospitals during 2020-2021.

Taken together, these most recent estimates “show an increasing trend in rates by adults with diabetes in the ED setting,” the authors concluded.

Emergency department (ED) visits by adults with diabetes increased by more than 25% since 2012, with the highest rates among Blacks and those aged over 65 years, a new data brief from the Centers for Disease Control and Prevention’s National Center for Health Statistics shows.

In 2021, diabetes was the eighth leading cause of death in the United States, according to the brief, published online on December 19, 2023. Its frequency is increasing in young people, and increasing age is a risk factor for hospitalization.

The latest data show that in 2020-2021, the overall annual ED visit rate was 72.2 visits per 1000 adults with diabetes, with no significant difference in terms of sex (75.1 visits per 1000 women vs 69.1 visits per 1000 men). By race/ethnicity, Blacks had the highest rates, at 135.5 visits per 1000 adults, followed by Whites (69.9) and Hispanics (52.3). The rates increased with age for both women and men, and among the three race/ethnic groups.

Comorbidities Count

The most ED visits were made by patients with diabetes and two to four other chronic conditions (541.4 visits per 1000 visits). Rates for patients without other chronic conditions were the lowest (90.2).

Among individuals with diabetes aged 18-44 years, ED visit rates were the highest for those with two to four other chronic conditions (402.0) and lowest among those with five or more other conditions (93.8).

Among patients aged 45-64 years, ED visit rates were the highest for those with two to four other chronic conditions (526.4) and lowest for those without other conditions (87.7). In the 65 years and older group, rates were the highest for individuals with two to four other chronic conditions (605.2), followed by five or more conditions (217.7), one other condition (140.6), and no other conditions (36.5).

Notably, the ED visit rates for those with two to four or five or more other chronic conditions increased with age, whereas visits for those with no other chronic conditions or one other condition decreased with age.

Decade-Long Trend

ED visit rates among adults with diabetes increased throughout the past decade, from 48.6 visits per 1000 adults in 2012 to 74.9 per 1000 adults in 2021. Rates for those aged 65 and older were higher than all other age groups, increasing from 113.4 to 156.8. Increases were also seen among those aged 45-64 years (53.1 in 2012 to 89.2 in 2021) and 18-44 (20.9 in 2012 to 26.4 in 2016, then plateauing from 2016-2021).

Severe obesity among preschool-age children from low-income families is on the rise in the United States, according to a new analysis of federal data.

An estimated 2% of children ages 2 to 4 years old had severe obesity in 2020, up from 1.8% in 2016, according to the report that appeared Dec. 18 in Pediatrics, a journal published by the American Academy of Pediatrics. 

The increase is “small but significant,” a group of experts not involved in the research wrote in a companion commentary published alongside the research.

The new data put an end to hopes that childhood obesity was on the retreat following a small decrease in rates from 2010 to 2016. Instead, the researchers noted that the new childhood obesity figures reflect those of the general population. In the United States, about 20% of children and teens are obese, and about 42% of adults are obese, according to the CDC.

This latest study looked for severe obesity, which was defined as being well above the 95th percentile for the combined height-weight measure known as body mass index. The figures are important because rates of severe obesity among young children can foreshadow health problems that may occur on a scale to warrant concerns among public health officials, policymakers, and health care professionals.

Compared with children who have moderate obesity, children with severe obesity “are at a greater risk of various health complications, including cardiovascular disease, metabolic syndrome, type 2 diabetes, fatty liver disease, and premature death,” the study authors wrote.

The largest increases from 2016 to 2020 in severe obesity were observed among 4-year-olds and among Hispanic children. When looking at state-level data, Alaska was the only state to report a decline in severe obesity among young children from 2016 to 2020.

The new estimates were drawn from data on children enrolled in the federal Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

“WIC is a federal assistance program that provides healthy foods, nutrition education, health care referrals, and other services to millions of low-income pregnant and postpartum women, as well as infants and children up to age 5, who are at nutritional risk,” the researchers noted.

The new figures indicate 16.6 million children ages 2 to 4 years old have severe obesity. Having severe obesity at these early ages is “nearly irreversible,” the authors of the commentary article noted, adding that little research exists that indicates how to effectively treat obesity before age 6.

“The study underscores the need for ongoing monitoring ... post pandemic of children’s health status,” a news release from the American Academy of Pediatrics stated. “It also further supports the need for children and families from households with lower incomes across the nation to have access to early clinical detection, such as health care screenings and referrals to effective family-based interventions to support healthy growth.”

Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are associated with a reduced risk for colorectal cancer (CRC) in patients with type 2 diabetes, with and without overweight or obesity, according to a new analysis.

In particular, GLP-1 RAs were associated with decreased risk compared with other antidiabetic treatments, including insulin, metformin, sodium-glucose cotransporter 2 (SGLT2) inhibitors, sulfonylureas, and thiazolidinediones.

More profound effects were seen in patients with overweight or obesity, “suggesting a potential protective effect against CRC partially mediated by weight loss and other mechanisms related to weight loss,” Lindsey Wang, an undergraduate student at Case Western Reserve University, Cleveland, Ohio, and colleagues wrote in JAMA Oncology.
 

Testing Treatments

GLP-1 RAs, usually given by injection, are approved by the US Food and Drug Administration to treat type 2 diabetes. They can lower blood sugar levels, improve insulin sensitivity, and help patients manage their weight.

Diabetes, overweight, and obesity are known risk factors for CRC and make prognosis worse. Ms. Wang and colleagues hypothesized that GLP-1 RAs might reduce CRC risk compared with other antidiabetics, including metformin and insulin, which have also been shown to reduce CRC risk.

Using a national database of more than 101 million electronic health records, Ms. Wang and colleagues conducted a population-based study of more than 1.2 million patients who had medical encounters for type 2 diabetes and were subsequently prescribed antidiabetic medications between 2005 and 2019. The patients had no prior antidiabetic medication use nor CRC diagnosis.

The researchers analyzed the effects of GLP-1 RAs on CRC incidence compared with the other prescribed antidiabetic drugs, matching for demographics, adverse socioeconomic determinants of health, preexisting medical conditions, family and personal history of cancers and colonic polyps, lifestyle factors, and procedures such as colonoscopy.

During a 15-year follow-up, GLP-1 RAs were associated with decreased risk for CRC compared with insulin (hazard ratio [HR], 0.56), metformin (HR, 0.75), SGLT2 inhibitors (HR, 0.77), sulfonylureas (HR, 0.82), and thiazolidinediones (HR, 0.82) in the overall study population.

For instance, among 22,572 patients who took insulin, 167 cases of CRC occurred, compared with 94 cases among the matched GLP-1 RA cohort. Among 18,518 patients who took metformin, 153 cases of CRC occurred compared with 96 cases among the matched GLP-1 RA cohort.

GLP-1 RAs also were associated with lower but not statistically significant risk than alpha-glucosidase inhibitors (HR, 0.59) and dipeptidyl-peptidase-4 (DPP-4) inhibitors (HR, 0.93).

In patients with overweight or obesity, GLP-1 RAs were associated with a lower risk for CRC than most of the other antidiabetics, including insulin (HR, 0.5), metformin (HR, 0.58), SGLT2 inhibitors (HR, 0.68), sulfonylureas (HR, 0.63), thiazolidinediones (HR, 0.73), and DPP-4 inhibitors (HR, 0.77).

Consistent findings were observed in women and men.

“Our results clearly demonstrate that GLP-1 RAs are significantly more effective than popular antidiabetic drugs, such as metformin or insulin, at preventing the development of CRC,” said Nathan Berger, MD, co-lead researcher, professor of experimental medicine, and member of the Case Comprehensive Cancer Center.
 

Targets for Future Research

Study limitations include potential unmeasured or uncontrolled confounders, self-selection, reverse causality, and other biases involved in observational studies, the research team noted.

Further research is warranted to investigate the effects in patients with prior antidiabetic treatments, underlying mechanisms, potential variation in effects among different GLP-1 RAs, and the potential of GLP-1 RAs to reduce the risks for other obesity-associated cancers, the researchers wrote.

“To our knowledge, this is the first indication this popular weight loss and antidiabetic class of drugs reduces incidence of CRC, relative to other antidiabetic agents,” said Rong Xu, PhD, co-lead researcher, professor of medicine, and member of the Case Comprehensive Cancer Center.

The study was supported by the National Cancer Institute Case Comprehensive Cancer Center, American Cancer Society, Landon Foundation-American Association for Cancer Research, National Institutes of Health Director’s New Innovator Award Program, National Institute on Aging, and National Institute on Alcohol Abuse and Alcoholism. Several authors reported grants from the National Institutes of Health during the conduct of the study.

Nearly three quarters of dedicated thyroid ultrasounds don’t identify biopsy-recommended nodules, and over a third don’t identify any nodules, new research finds.

“The number of thyroid ultrasounds performed in the United States has increased fivefold since 2002. This substantial increase produces a significant strain on healthcare resources and leads to over-detection and overtreatment of benign thyroid nodules and small, indolent cancers with questionable clinical relevance,” wrote Elena Kennedy, MD, then a medical student in the department of surgery at the University of Wisconsin School of Medicine and Public Health, Madison, and colleagues.

The data, published online in Thyroid, come from a retrospective chart analysis of more than 1700 people who underwent dedicated (ie, specifically to look for a nodule) thyroid ultrasounds at a tertiary academic center. The rates of detecting both nodules and biopsy-recommended nodules were highest when the indication was a nodule seen incidentally on other imaging (aka “incidentaloma”) and lowest when the ultrasound was ordered because the patient had either metabolic or compressive symptoms.

And for the most commonly listed indication, a suspected palpable nodule, nearly half of the ultrasounds found no nodule, and only one in five detected a nodule that warranted a biopsy.

The principal investigator of the study David O. Francis, MD, an otolaryngologist at the University of Wisconsin, Madison, said in an interview, “Thyroid cancer has grown in incidence three to four times over the last 30 years without a good explanation for why…It seems to be that we’re detecting smaller and smaller nodules…Why are people being referred for all these ultrasounds? We looked for the upstream factors.”

One clear clinical implication of the new data, Dr. Francis noted, is that “if someone has compressive symptoms including dysphagia, swallowing problems, voice change, or globus sensation, ultrasound should not be the first way to work them up…It would be smarter to have someone evaluate their voice or their swallowing to see if there’s another reason besides the thyroid. The thyroid would have to get pretty big to cause dysphagia or swallowing problems.”
 

No Current Guidelines Advise When not to Order a Thyroid Ultrasound

Problematically, while there are professional society guidelines for what to do when a thyroid “incidentaloma” is found and other specific situations, there are no overall guidelines addressing when it’s appropriate to order a thyroid ultrasound, Dr. Kennedy, now an otolaryngology resident at the Indiana University of Indianapolis, and colleagues, point out.

According to Dr. Francis, “Ultrasounds are low cost and low risk. Those two factors result in people ordering more tests…The problem with that is we find things, and then we have to figure out what to do with them. That leads to incidentalomas, the surveillance, worry and anxiety, and costs…It’s tricky. We don’t want to discourage people from ever ordering ultrasounds, but there need to be some guidelines around when it’s appropriate to order.”

Asked to comment, Trevor E. Angell, MD, associate medical director of Thyroid Center at Keck School of Medicine of the University of Southern California, Los Angeles, said that the study is “clinically very important.”

Dr. Angell pointed out that the current American Thyroid Association (ATA) guidelines on thyroid nodule management, of which he is an author, recommend ultrasound for a known or suspected nodule. But he added, “there certainly should be a message that obtaining ultrasound for these other reasons are less likely to identify a nodule or anything causative. Whether it’s gastroesophageal reflux or allergic rhinitis or vocal cord dysfunction, an ultrasound isn’t a good test for those either.”

Dr. Angell said that the next ATA thyroid nodule guidelines, expected out in 2024, will address this topic more fully, but he couldn’t provide more specific information because the document is still in development. He did say, however, “Addressing when not to do an ultrasound will be an important consideration in the next guidelines.”
 

Low Detection Rates for Most Indications

The retrospective observational cohort study included 1739 adults (76% women; mean age, 53 years) who underwent dedicated thyroid ultrasounds between 2017 and 2019. In most cases, the recommendation for biopsy was determined using the American College of Radiology TI-RADS system, based on nodule size and TI-RADS category.

The most common indication for thyroid ultrasound, suspected palpable nodule, accounted for 40% of those performed. Follow-up for an “incidentaloma” was the indication in 28% of patients, and referral for compressive and metabolic symptoms accounted for 13% and 6% of ultrasounds, respectively.

Among all ultrasounds performed, 62% identified a thyroid nodule. Patients referred for incidental findings had the highest percentage of ultrasounds with thyroid nodules present at 94%. By contrast, in those referred for suspected palpable nodule on exam and for compressive symptoms, nodules were identified on 55% and 39% of ultrasounds, respectively. Patients with metabolic symptoms had a nodule identified on ultrasound 43% of the time. Among those referred for high risk factors, 57% had a nodule present.

Overall, only 27% of ultrasounds identified a thyroid nodule that was recommended for a biopsy. Again, those referred because of an incidental imaging finding had the highest percentage (55%), followed by those referred for a suspected palpable nodule (21%), high risk factors (20%), combined indications (16%), metabolic symptoms (10%), and compressive symptoms (6%).

Mean nodule size was largest among the patients referred for incidentalomas (2.4 cm), whereas all the other groups had mean nodule sizes between 1.2 cm and 1.8 cm, a significant difference (P < .05). The median size of nodules among those referred to ultrasound for a suspected palpable nodule was 1.4 cm.

“That’s pretty small. It would have had to be in the front of the thyroid where they could actually touch it. I would argue that the number of clinicians who actually palpated something was smaller. We’ve done several projects looking at how small a nodule a clinician can actually feel in the thyroid gland from the neck. It turns out we’re pretty bad at physical examination of the thyroid. This paper kind of reinforces that,” Dr. Francis said in an interview.

Patients with incidental nodules were over 10 times more likely to have a nodule found on an ultrasound than those referred for a suspected palpable nodule on exam (odds ratio [OR], 10.6). Conversely, those referred for compressive symptoms were half as likely to have an identifiable nodule compared with those referred for physical exam findings (OR, 0.5).

The odds of finding a nodule increased with age, especially for those aged ≥ 65 years compared with those younger than 45 years (OR, 3.6). Women were twice as likely to have a nodule found on thyroid ultrasound (OR, 2.0). Results were similar for the biopsy-recommended nodules, except that there was no difference between sexes (female vs male OR, 1.2).

Dr. Angell called the study “a very robust comprehensive evaluation,” but also noted that the single center source is a limitation. “It would be nice to have those big databases of national healthcare settings, but getting that granular level of information about why something was done is nearly impossible in that context.”

Dr. Kennedy, Dr. Francis, and Dr. Angell have no disclosures.

Nearly three quarters of dedicated thyroid ultrasounds don’t identify biopsy-recommended nodules, and over a third don’t identify any nodules, new research finds.

“The number of thyroid ultrasounds performed in the United States has increased fivefold since 2002. This substantial increase produces a significant strain on healthcare resources and leads to over-detection and overtreatment of benign thyroid nodules and small, indolent cancers with questionable clinical relevance,” wrote Elena Kennedy, MD, then a medical student in the department of surgery at the University of Wisconsin School of Medicine and Public Health, Madison, and colleagues.

The data, published online in Thyroid, come from a retrospective chart analysis of more than 1700 people who underwent dedicated (ie, specifically to look for a nodule) thyroid ultrasounds at a tertiary academic center. The rates of detecting both nodules and biopsy-recommended nodules were highest when the indication was a nodule seen incidentally on other imaging (aka “incidentaloma”) and lowest when the ultrasound was ordered because the patient had either metabolic or compressive symptoms.

And for the most commonly listed indication, a suspected palpable nodule, nearly half of the ultrasounds found no nodule, and only one in five detected a nodule that warranted a biopsy.

The principal investigator of the study David O. Francis, MD, an otolaryngologist at the University of Wisconsin, Madison, said in an interview, “Thyroid cancer has grown in incidence three to four times over the last 30 years without a good explanation for why…It seems to be that we’re detecting smaller and smaller nodules…Why are people being referred for all these ultrasounds? We looked for the upstream factors.”

One clear clinical implication of the new data, Dr. Francis noted, is that “if someone has compressive symptoms including dysphagia, swallowing problems, voice change, or globus sensation, ultrasound should not be the first way to work them up…It would be smarter to have someone evaluate their voice or their swallowing to see if there’s another reason besides the thyroid. The thyroid would have to get pretty big to cause dysphagia or swallowing problems.”
 

No Current Guidelines Advise When not to Order a Thyroid Ultrasound

Problematically, while there are professional society guidelines for what to do when a thyroid “incidentaloma” is found and other specific situations, there are no overall guidelines addressing when it’s appropriate to order a thyroid ultrasound, Dr. Kennedy, now an otolaryngology resident at the Indiana University of Indianapolis, and colleagues, point out.

According to Dr. Francis, “Ultrasounds are low cost and low risk. Those two factors result in people ordering more tests…The problem with that is we find things, and then we have to figure out what to do with them. That leads to incidentalomas, the surveillance, worry and anxiety, and costs…It’s tricky. We don’t want to discourage people from ever ordering ultrasounds, but there need to be some guidelines around when it’s appropriate to order.”

Asked to comment, Trevor E. Angell, MD, associate medical director of Thyroid Center at Keck School of Medicine of the University of Southern California, Los Angeles, said that the study is “clinically very important.”

Dr. Angell pointed out that the current American Thyroid Association (ATA) guidelines on thyroid nodule management, of which he is an author, recommend ultrasound for a known or suspected nodule. But he added, “there certainly should be a message that obtaining ultrasound for these other reasons are less likely to identify a nodule or anything causative. Whether it’s gastroesophageal reflux or allergic rhinitis or vocal cord dysfunction, an ultrasound isn’t a good test for those either.”

Dr. Angell said that the next ATA thyroid nodule guidelines, expected out in 2024, will address this topic more fully, but he couldn’t provide more specific information because the document is still in development. He did say, however, “Addressing when not to do an ultrasound will be an important consideration in the next guidelines.”

VANCOUVER — Glucagon-like peptide-1 (GLP-1) agonists, like semaglutide, liraglutide, and the newly US Food and Drug Administration–approved tirzepatide, not only are gaining popularity among the public for weight loss but also are the focus of considerable attention from gastroenterology researchers.

The robust interest in GLP-1 agonists was on full display here at the annual meeting of the American College of Gastroenterology, with investigators sharing results on which agent is most effective for weight loss, how they compare to bariatric surgery for weight loss or prevention of metabolic dysfunction–associated steatotic liver disease, and their potential role to prevent regain after weight-loss surgery.
 

Head-to-Head Comparison

Tirzepatide 15 mg emerged as superior to other GLP-1 agonists for weight loss, for example, in a network meta-analysis of randomized controlled trials looking into obesity management.

Tirzepatide 15 mg was associated with the most effective mean weight loss at just over 15% when Jena Velji-Ibrahim, MD, and colleagues combined data from 14 studies with 18,714 participants with overweight or obesity but without diabetes.

Next up in order of weight-loss efficacy was tirzepatide 10 mg with 13% mean weight loss, semaglutide 2.4 mg with just over 11% mean weight loss, and tirzepatide 5 mg with almost 10% mean weight loss. The only outlier was dulaglutide 0.75 mg, which was linked to about 8% weight gain.

“While clinical trials have been conducted to assess the weight-loss efficacy of GLP-1 agonists, there has been limited head-to-head comparisons, and the data that has been obtained has been quite inconsistent,” Dr. Velji-Ibrahim said when presenting results at the meeting.

Researchers found little difference in efficacies between tirzepatide 15 mg and 10 mg, suggesting both are a viable option for weight loss, said Dr. Velji-Ibrahim of Prisma Health Greenville Memorial Hospital and University of South Carolina School of Medicine in Greenville.

She also reported similar efficacies between oral semaglutide 50 mg and subcutaneous semaglutide 2.4 mg, “meaning that we have another option for weight management.”

Side effects among the different GLP-1 agonists, and among the same agent at different doses, were not significantly different.
 

Comparison With Bariatric Surgery for Reducing Major Adverse Cardiovascular Events (MACE)

For many years, bariatric surgeons have pointed to the health benefits of weight-loss surgery in the right candidates, including a reduced risk for adverse cardiovascular events.

The weight loss associated with GLP-1 agonists has likewise shown benefits in reducing MACE. However, it remains unclear if one of these weight-loss strategies is better than the other in reducing these outcomes.

To determine this, researchers compared 118,828 people who had bariatric surgery to another propensity-matched group of 118,828 others prescribed GLP-1 agonists. They included adults with a body mass index (BMI) of 35 or higher in the national TriNetX database.

The multicenter, retrospective study revealed bariatric surgery was superior in reducing the risk for heart failure, MACE, and cerebrovascular disease at 3, 5, 7, and 10 years. At 10 years, for example, bariatric surgery was associated with 31% fewer composite cardiovascular events than the GLP-1 agonists.

“Our results suggest that bariatric surgery is more effective than GLP-1 analogs in preventing adverse cardiovascular events in obese patients,” Ayowumi A. Adekolu, MD, an internal medicine resident at West Virginia School of Medicine in Morgantown, said in audio comments accompanying his ePoster at the meeting. “Although these findings highlight the benefit of bariatric surgery in mitigating adverse cardiovascular events, well-designed prospective studies are necessary to confirm these benefits in this patient population.”

Possible Role in Fatty Liver Disease Prevention
 

In another large multicenter study from the same institution, Ethan M. Cohen, MD, along with co-author Dr. Adekolu and others, compared the effectiveness of bariatric surgery to GLP-1 agonists for preventing nonalcoholic fatty liver disease (NAFLD). Since the study was conducted, the official name of NAFLD has changed to metabolic dysfunction–associated steatotic liver disease.

Dr. Cohen and colleagues evaluated data from the TriNetX database and included adults with a BMI of 35 or higher. They propensity matched 124,022 people who had sleeve gastrectomy or Roux-en-Y gastric bypass to another 124,022 others prescribed GLP-1 agonists. Again, they looked at outcomes at 3, 5, 7, and 10 years.

They found bariatric surgery superior to GLP-1 agonists for reducing the risk of developing NAFLD. Relative risk reduction was 25% at 3 years, 28% at 5 years, 27% at 7 years, and 26% at 10 years.

Although not to the same extent as surgery in this study, GLP-1–associated weight loss did reduce risks as well.

“An important aspect of this is that for some of these people, bariatric surgery is not even an option,” Dr. Cohen said in an interview, citing as an example those who do not meet the criteria for surgery.

Dr. Cohen and colleagues plan to continue the study with a larger number of participants.
 

Real-World Weight Regain

In another instance where a surgical procedure trumped GLP-1 agonists, revisional endoscopic sleeve gastroplasty (ESG) offered significantly higher weight loss than GLP-1 agonists among people who regained weight following initial weight-loss surgery, according to a case-control real-world study presented at the meeting.

“Laparoscopic sleeve gastrectomy [LSG] is a frequently performed bariatric surgery worldwide resulting in significant weight loss and improvement in obesity-related comorbidities,” said Firas Bahdi, MD, gastroenterology fellow at the David Geffen School of Medicine at University of California, Los Angeles. “Despite its success, around one third of patients, unfortunately, develop weight regain warranting intervention.”

Dr. Bahdi and colleagues retrospectively studied 68 adults prescribed subcutaneous semaglutide or tirzepatide after LSG, another 20 who had ESG for weight regain after LSG, and 87 controls with intact stomachs who also took GLP-1 agonists for weight loss.

They found that the ESG group experienced a significantly higher percentage of total body weight loss at 3 months than the GLP-1 group (10% vs 4.3%, respectively; P = .0001). Similarly, at the 6-month follow-up, the ESG group experienced 11.5% total body weight loss compared to 6.8% in the GLP-1 group (P = .03).

The GLP-1 after LSG group still fared better than the GLP-1 control group of people who never had surgery. Total body weight loss was 4.3% vs 5.7% at 3 months (P = .02), 6.8% vs 9.2% at 6 months (P = .02), and 9.2% vs 12.7% at 12 months (P = .03).

“In this real-world experience, revisional ESG offers significantly more weight loss than GLP-1 agonists for patients with weight regain, while also avoiding the challenges of medication refills, making it an attractive option,” Dr. Bahdi said.

Future multicenter studies are warranted to confirm these results and explore physiological explanations, he added.

The study received an Outstanding Research Award in the Obesity Category (Trainee).

Dr. Velji-Ibrahim, Dr. Adekolu, Dr. Cohen, and Dr. Bahdi indicated no relevant financial relationships.

Researchers found little difference in efficacies between tirzepatide 15 mg and 10 mg, suggesting both are a viable option for weight loss, said Dr. Velji-Ibrahim of Prisma Health Greenville Memorial Hospital and University of South Carolina School of Medicine in Greenville.

She also reported similar efficacies between oral semaglutide 50 mg and subcutaneous semaglutide 2.4 mg, “meaning that we have another option for weight management.”

Side effects among the different GLP-1 agonists, and among the same agent at different doses, were not significantly different.
 

Comparison With Bariatric Surgery for Reducing Major Adverse Cardiovascular Events (MACE)

For many years, bariatric surgeons have pointed to the health benefits of weight-loss surgery in the right candidates, including a reduced risk for adverse cardiovascular events.

The weight loss associated with GLP-1 agonists has likewise shown benefits in reducing MACE. However, it remains unclear if one of these weight-loss strategies is better than the other in reducing these outcomes.

To determine this, researchers compared 118,828 people who had bariatric surgery to another propensity-matched group of 118,828 others prescribed GLP-1 agonists. They included adults with a body mass index (BMI) of 35 or higher in the national TriNetX database.

The multicenter, retrospective study revealed bariatric surgery was superior in reducing the risk for heart failure, MACE, and cerebrovascular disease at 3, 5, 7, and 10 years. At 10 years, for example, bariatric surgery was associated with 31% fewer composite cardiovascular events than the GLP-1 agonists.

“Our results suggest that bariatric surgery is more effective than GLP-1 analogs in preventing adverse cardiovascular events in obese patients,” Ayowumi A. Adekolu, MD, an internal medicine resident at West Virginia School of Medicine in Morgantown, said in audio comments accompanying his ePoster at the meeting. “Although these findings highlight the benefit of bariatric surgery in mitigating adverse cardiovascular events, well-designed prospective studies are necessary to confirm these benefits in this patient population.”

Possible Role in Fatty Liver Disease Prevention
 

In another large multicenter study from the same institution, Ethan M. Cohen, MD, along with co-author Dr. Adekolu and others, compared the effectiveness of bariatric surgery to GLP-1 agonists for preventing nonalcoholic fatty liver disease (NAFLD). Since the study was conducted, the official name of NAFLD has changed to metabolic dysfunction–associated steatotic liver disease.

Dr. Cohen and colleagues evaluated data from the TriNetX database and included adults with a BMI of 35 or higher. They propensity matched 124,022 people who had sleeve gastrectomy or Roux-en-Y gastric bypass to another 124,022 others prescribed GLP-1 agonists. Again, they looked at outcomes at 3, 5, 7, and 10 years.

They found bariatric surgery superior to GLP-1 agonists for reducing the risk of developing NAFLD. Relative risk reduction was 25% at 3 years, 28% at 5 years, 27% at 7 years, and 26% at 10 years.

Although not to the same extent as surgery in this study, GLP-1–associated weight loss did reduce risks as well.

“An important aspect of this is that for some of these people, bariatric surgery is not even an option,” Dr. Cohen said in an interview, citing as an example those who do not meet the criteria for surgery.

Dr. Cohen and colleagues plan to continue the study with a larger number of participants.
 

Real-World Weight Regain

In another instance where a surgical procedure trumped GLP-1 agonists, revisional endoscopic sleeve gastroplasty (ESG) offered significantly higher weight loss than GLP-1 agonists among people who regained weight following initial weight-loss surgery, according to a case-control real-world study presented at the meeting.

“Laparoscopic sleeve gastrectomy [LSG] is a frequently performed bariatric surgery worldwide resulting in significant weight loss and improvement in obesity-related comorbidities,” said Firas Bahdi, MD, gastroenterology fellow at the David Geffen School of Medicine at University of California, Los Angeles. “Despite its success, around one third of patients, unfortunately, develop weight regain warranting intervention.”

Dr. Bahdi and colleagues retrospectively studied 68 adults prescribed subcutaneous semaglutide or tirzepatide after LSG, another 20 who had ESG for weight regain after LSG, and 87 controls with intact stomachs who also took GLP-1 agonists for weight loss.

They found that the ESG group experienced a significantly higher percentage of total body weight loss at 3 months than the GLP-1 group (10% vs 4.3%, respectively; P = .0001). Similarly, at the 6-month follow-up, the ESG group experienced 11.5% total body weight loss compared to 6.8% in the GLP-1 group (P = .03).

The GLP-1 after LSG group still fared better than the GLP-1 control group of people who never had surgery. Total body weight loss was 4.3% vs 5.7% at 3 months (P = .02), 6.8% vs 9.2% at 6 months (P = .02), and 9.2% vs 12.7% at 12 months (P = .03).

“In this real-world experience, revisional ESG offers significantly more weight loss than GLP-1 agonists for patients with weight regain, while also avoiding the challenges of medication refills, making it an attractive option,” Dr. Bahdi said.

Future multicenter studies are warranted to confirm these results and explore physiological explanations, he added.

The study received an Outstanding Research Award in the Obesity Category (Trainee).

Dr. Velji-Ibrahim, Dr. Adekolu, Dr. Cohen, and Dr. Bahdi indicated no relevant financial relationships.
