Background: Chemerin is an important risk factor of insulin resistance. Non-alcoholic fatty liver has typical characteristics of insulin resistance. The aim of this study was to explore the potential role of chemerin in NAFLD.
Methods: 45 subjects included 22 control subjects (A group) and 23 subjects diagnosed with non-alcoholic fatty liver disease (B group) participated in the study. 23 patients in the NAFLD group received oral daily metformin at a dose of 20 mg/kg/day for 24 weeks follow-up. Chemerin and insulin resistance markers were determined at baseline and 24 weeks.
Results: The levels of WHR, BMI, FINS, HOMA-IR, TG, ALT, AST, and Chemerin in B group were significantly higher than A group. After 24 weeks of metformin treatment, the levels of WHR, AST, ALT, TG, chemerin and HOMA-IR were significantly reduced (p < 0.05) and other indexes were not changed significantly. Correlation analysis indicated that serum chemerin concentrations were positively correlated with BMI, WHR, HOMA-IR, FINS, TG, ALT, and AST levels. Logistic regression analysis showed chemerin, TG, and ALT were independent variables associated with NAFLD.
Conclusions: These findings showed a significant increase of chemerin level in NAFLD patients. Metformin treatment can improve NAFLD and decrease the level of chemerin. Chemerin, TG, and ALT were independent variables associated with NAFLD.
