Objectives: To evaluate the effect of vildagliptin alone and in combination with metformin or rosiglitazone on murine hepatic steatosis in diet-induced nonalcoholic fatty liver disease (NAFLD). Materials and Methods: Male C57BL/6 mice were fed with high fat diet (60 Kcal %) and fructose (40%) in drinking water for 60 days to induce NAFLD. After the induction period, animals were divided into different groups and treated with vildagliptin (10 mg/kg), metformin (350 mg/kg), rosiglitazone (10 mg/kg), vildagliptin (10 mg/kg) + metformin (350 mg/kg), or vildagliptin (10 mg/kg) + rosiglitazone (10 mg/kg) orally for 28 days. Following parameters were measured: body weight, food intake, plasma glucose, triglyceride (TG), total cholesterol, liver function tests, and liver TG. Liver histopathology was also examined. Results: Oral administration of vildagliptin and rosiglitazone in combination showed a significant reduction in fasting plasma glucose, hepatic steatosis, and liver TGs. While other treatments showed less or no improvement in the measured parameters. Conclusions: These preliminary results demonstrate that administration of vildagliptin in combination with rosiglitazone could be a promising therapeutic strategy for the treatment of NAFLD.
