Objective To detect the clinic effects of exenatide on liver in type 2 diabetes mellitus (T₂DM) patients combined with nonalcoholic fatty liver disease (NAFLD) and explore its mechanisms and clinical safety. Methods A total of 96 T₂DM combined with NAFLD patients were enrolled in this study. Patients were randomly divided into fetmormin control group (n=48) and fetmormin+exenatide observation group (n=48). The patients in control group were given metformin, starting dose of 500 mg each time, twice daily, combined with specific patient's condition to adjust the dose. The patients in treatment group were given metformin and exenatide at 60 min before breakfast and 60 min before dinner, which was treated for 24 weeks. The FBG, PPG, TG, TC, ALT, and AST was compared. FGF19 and FGF21 were detected by ELISA analysis. The rate of adverse reaction was compared. Results After treatment, FBG, PPG, TG, TC, ALT, AST, BMI, waistline, and B ultrasound in liver fat storage were all decreased (P<0.05, 0.01). However, which were all lower in observation group than that in control group (P<0.05). After treatment, FGF19 and FGF21 were both increased (P<0.05, 0.01). However, which were both higher in observation group than those in control group (P<0.05). The clinical effect rate in observation was 85.4%, which was higher than that of 64.6% in control group (P<0.05). The rates of adverse reaction were 12.5% in treatment group and 10.4% in control group. There was no significant difference between the two groups (P>0.05). Conclusion Exenatide has a significant role in the improvement of blood glucose, blood lipid, and liver function in T₂DM combined with NAFLD patients, with significantly clinical efficacy and safety.
