Purpose: Diabetes mellitus is a chronic disease often associated with nonalcoholic steatohepatitis (NASH) and obesity. Both obesity and NASH are closely related to inflammation. In this study, we examined how exenatide, a glucagon-like peptide 1 analog, affects inflammatory and NASH-related markers in patients with diabetes. Methods: This retrospective study was conducted on 100 patients who visited our hospital with a diagnosis of type 2 diabetes mellitus. NASH-related indices and inflammatory indices were calculated from data obtained at baseline and at the third month of exenatide treatment. All data were analyzed first in all patients, and then the patients were grouped according to glycosylated hemoglobin A1c (HbA1c) levels of <8% or ≥8% and body mass index (BMI) of <40 or ≥40 kg/m 2 and their data were reanalyzed. Results: A highly significant improvement was found in the conventional lipid profile. Among NASH-related indices, the nonalcoholic fatty liver disease (NAFLD) fibrosis score and aspartate aminotransferase-platelet ratio index (APRI) showed statistically significant decreases ( P < 0.001 and P = 0.016, respectively). In particular, these significant decreases were independent of BMI and glycemic parameters. No statistically significant change was found in inflammatory indices. The decreases in NAFLD fibrosis score and APRI were statistically more significant in the group with HbA1c ≥8% ( P = 0.021 and P = 0.002, respectively) and the group with BMI ≥40 kg/m 2 ( P = 0.002 and P = 0.029, respectively). Conclusions: Besides its established effects, such as lowering fasting plasma glucose levels and weight loss, exenatide exerts positive effects on the conventional lipid profile and NASH-associated indexes.
