This study aimed to evaluate the efficacy and safety of sitagliptin for treating Chinese patients with type 2 diabetes mellitus (T2DM) with nonalcoholic fatty liver disease (NAFLD).


In total, 72 Chinese T2DM patients with NAFLD were divided randomly into two groups of 36 patients each group. All 72 patients were assigned to receive either sitagliptin or diet and exercise for 52 weeks between January 2013 and December 2015. The outcomes’ measurements included serum levels of hemoglobin A1c, fasting plasma glucose, aspartate aminotransferase, and alanine aminotransferase.


Seventy patients completed the study. Sitagliptin showed greater efficacy than the diet and exercise in decreasing the hemoglobin A1c and fasting plasma glucose levels at weeks 13, 26, 39, and 52. In addition, no significant changes in the average aspartate aminotransferase and alanine aminotransferase levels were found during the 52-week follow-up in both the sitagliptin and the control groups.


The results of this study indicate that sitagliptin is an effective and safe treatment for patients with T2DM and NAFLD.
