Background: Metabolic dysfunction-associated steatotic liver
disease (MASLD) significantly impacts global health, with a prevalence
affecting roughly 25% of adults worldwide. GLP-1 receptor agonists
(GLP-1RAs) offer potential therapeutic benefits beyond glycemic control,
including improvement in hepatic steatosis, inflammation, and fibrosis.
Objectives: This study aims to systematically review and
meta-analyze randomized clinical trials to evaluate the efficacy and
safety of GLP-1RAs in MASLD patients, focusing on hepatic outcomes,
cardiovascular outcomes, anthropometric measurements, and mortality.
Methods: Following PRISMA guidelines, a comprehensive database
search was conducted to include RCTs assessing GLP-1RAs’ effects on
MASLD. Quality assessment was conducted using the Revised Cochrane Risk
of Bias tool. Our meta-analysis utilized a random-effects model,
calculating standardized mean differences for continuous outcomes to
determine the agents’ efficacy and safety. Additionally, funnel plots
were generated to assess publication bias, ensuring the integrity of our
meta-analytical findings. Results: The review included 27
trials, revealing GLP-1RAs significantly improved hepatic function
markers (ALT, AST, GGT, and liver fat content) and cardiovascular risk
factors (fasting blood sugar, HbA1c levels, lipid profiles).
Additionally, GLP-1RAs were associated with significant reductions in
body weight, BMI, subcutaneous fat, and waist circumference.
Conclusion: GLP-1RAs demonstrate a promising therapeutic role
in managing MASLD, offering benefits that extend to improving liver
function, mitigating cardiovascular risk, and promoting weight loss.
Further research is needed to confirm these findings and optimize
GLP-1RAs’ usage in MASLD treatment.
