Study Finds GLP-1 RAs May Lower Liver and Heart Complications in MASLD Patients with Diabetes
USA: A recent study published in Diabetes, Obesity and Metabolism has reported that the use of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) is linked to a lower risk of liver disease progression, major acute cardiovascular events (MACE), and all-cause mortality in individuals with diabetes and hepatic steatosis.
The research, conducted by Ishak A. Mansi from the Department of Internal Medicine, University of Central Florida College of Medicine, Orlando, Florida, and colleagues, emphasizes the potential role of GLP-1 RAs in addressing both hepatic and cardiovascular complications in this high-risk population.
Metabolically-dysfunction-associated steatotic liver disease (MASLD), previously referred to as non-alcoholic fatty liver disease, is now recognized as the leading cause of chronic liver disease in the United States. The condition not only advances to cirrhosis in some patients but is also strongly associated with an increased risk of severe cardiovascular outcomes. Recognizing the dual burden of liver and heart complications, the study aimed to evaluate whether GLP-1 RA therapy could offer protective benefits compared to dipeptidyl-peptidase-4 inhibitors (DPP4i).
The researchers conducted a retrospective cohort analysis using national data from the U.S. Department of Veteran Affairs, including individuals diagnosed with non-alcoholic hepatic steatosis who began treatment with either GLP-1 RAs or DPP4i between October 2005 and September 2021. Both groups were carefully matched using propensity scores across 73 baseline characteristics to ensure comparability.
The following were the key findings of the study:
- The study analyzed 58,157 matched pairs of GLP-1 RA and DPP4i users.
- GLP-1 RA users had a lower rate of liver disease progression at 6.1% compared to 7.0% among DPP4i users.
- The odds ratio (OR) for liver disease progression was 0.86 with a 95% confidence interval (CI) of 0.82–0.90.
- Patients using GLP-1 RAs showed a reduced incidence of major cardiovascular events (MACE) and all-cause mortality, with 11.1% affected compared to 14.7% in the DPP4i group.
- The odds ratio for MACE/death was 0.72 with a 95% CI of 0.70–0.75, indicating significant cardiovascular protection.
- Treating 109 individuals with GLP-1 RAs would prevent one additional case of liver disease progression.
- Only 27 individuals would need treatment with GLP-1 RAs to avert one case of MACE or death.
The findings highlight the importance of a comprehensive management approach in patients with MASLD and diabetes. According to the authors, focusing solely on preventing liver disease progression may not be sufficient. Instead, therapies that simultaneously address cardiovascular risk should be prioritized to improve overall outcomes.
"The large-scale real-world analysis adds to the growing body of evidence supporting GLP-1 RAs as a therapeutic option with benefits extending beyond glycemic control, positioning them as valuable agents in reducing both hepatic and cardiovascular complications in this vulnerable patient group," the authors concluded.
