Abstract

To investigate changes in skeletal muscle mass and fat fraction in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) and type 2 diabetes mellitus (T2DM) undergoing treatment with Semaglutide for 6months. This single-arm pilot study included 21 patients with MASLD who received semaglutide for T2DM. Body weight, metabolic parameters, liver enzymes, fibrosis markers, skeletal muscle index (cm2/m2), and fat fraction (%) at the L3 level using the two-point Dixon method on magnetic resonance imaging (MRI), as well as liver steatosis and liver stiffness assessed using MRI-based proton density fat fraction (MRI-PDFF) and MR elastography, respectively, were prospectively examined before and 6 months after semaglutide administration. The mean age of the patients was 53 years and 47.6% were females. The median liver steatosis-fraction (%) and skeletal muscle steatosis-fraction values (%) significantly decreased (22.0 vs 12.0; P = .0014) and (12.8 vs 9.9; P = .0416) at baseline and 6 months, respectively, while maintaining muscle mass during treatment. Semaglutide also dramatically reduced hemoglobin A1c (%) (6.8 vs 5.8, P = .0003), AST (IU/L) (54 vs 26, P < .0001), ALT (IU/L) (80 vs 34, P = .0004), and γ-GTP (IU/L) levels (64 vs 34, P = .0007). Although not statistically significant, Body weight (kg) (79.9 vs 77.4), body mass index (BMI) (kg/m2) (28.9 vs 27.6), and liver stiffness (kPa) (28.9 vs 27.6) showed a decreasing trend. Fibrosis markers such as M2BPGi, type IV collagen, and skeletal muscle area did not differ. Semaglutide demonstrated favorable effects on liver and skeletal muscle steatosis, promoting improved liver function and diabetic status.
