AbstractNon-alcoholic fatty liver disease (NAFLD) is currently the most common cause of chronic liver disease. However, the treatment is limited. The aim of this meta-analysis was to evaluate the effects and safety of sitagliptin, a selective inhibitor of dipeptidyl peptidase-4 (DPP-4I), in treating NAFLD. Studies were sourced from electronic databases including PubMed, CENTRAL (Cochrane Controlled Trials Register), Embase, Medline, Web of Science, Clinical Trials, and CNKI to identify all randomized controlled clinical trials (RCTs) and non-RCTs in adult patients with NAFLD. Key outcomes were changes in serum levels of liver enzymes and improvement in hepatic histology and fat content measured by imaging or liver biopsy. Stata14.0 and RevMan5.3 were used for the meta-analysis. Seven studies with 269 NAFLD patients were included. Compared to the control group, sitagliptin treatment improved serum gamma-glutamyl transpeptidase (GGT) levels in the RCT subgroup (SMD = 0.79, 95% CI: 0.01–1.58). However, there was no significant improvement in serum alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels following sitagliptin treatment. Four of the included studies performed liver imaging, but sitagliptin treatment did not result in a significant reduction in liver fat content. Only five participants developed sitagliptin-related gastrointestinal discomfort. Our study suggests that sitagliptin effects individuals with NAFLD by improving serum GGT. Although sitagliptin is safe and well tolerated in NAFLD patients, it exerts no beneficial effects on liver transaminase and liver fat content in these patients.

Abstract Background Although thyroid function has been demonstrated to be associated with non-alcoholic fatty liver disease (NAFLD) in different population, the prevalence and features of NAFLD in hyperthyroidism have not been reported. The present study aims to investigate the prevalence of NAFLD and association of thyroid function and NAFLD in hyperthyroidism patients. Methods This cross-sectional study was performed in Zhongshan Hospital, Fudan University, China. A total 117 patients with hyperthyroidism were consecutively recruited from 2014 to 2015. Thyroid function and other clinical features were measured, liver fat content was measured by color Doppler ultrasonically, NAFLD was defined in patients with liver fat content more than 9.15%. Statistical analyses were performed with SPSS software package version 13.0. Results The prevalence of NAFLD was 11.97% in hyperthyroidism. Patient with NAFLD had lower free triiodothyronine (FT3) and free thyroxine (FT4) levels than patients without NAFLD (P < 0.05). After adjusting for age, gender, metabolic parameters and inflammation factors, higher FT3 were associated with lower liver fat content (β = − 0.072, P = 0.009) and decreased odds ratio of NAFLD (OR = 0.267, 95%CI 0.087–0.817, P = 0.021). Conclusions FT3 level was negatively associated with the liver fat content in this population. These results may provide new evidence in the role of thyroid hormone on the regulation of liver fat content and NAFLD.

Abstract Background: Although thyroid function has been demonstrated to be associated with non-alcoholic fatty liver disease (NAFLD) in different population, the prevalence and features of NAFLD in hyperthyroidism have not been reported. The present study aims to investigate the prevalence of NAFLD and association of thyroid function and NAFLD in hyperthyroidism patients.Methods: This cross-sectional study was performed in Zhongshan Hospital, Fudan University, China. A total 117 patients with hyperthyroidism were consecutively recruited from 2014-2015. Thyroid function and other clinical features were measured, liver fat content was measured by color Doppler ultrasonically,NAFLD was defined in patients with liver fat content more than 9.15% . Statistical analyses were performed with SPSS software package version 13.0.Results: The prevalence of NAFLD was 11.97% in hyperthyroidism. Patient with NAFLD had lower free triiodothyronine (FT3) and free thyroxine (FT4) levels than patients without NAFLD (P < 0.05). After adjusting for age, gender, metabolic parameters and inflammation factors, higher FT3 were associated with lower liver fat content (β=-0.072, P=0.009) and decreased odds ratio of NAFLD (OR=0.267, 95%CI 0.087-0.817, P=0.021). Conclusions: FT3 level was negatively associated with the liver fat content in this population. These results may provide new evidence in the role of thyroid hormone on the regulation of liver fat content and NAFLD.
