Background & Aims: Non-alcoholic fatty liver disease (NAFLD) is associated with insulin resistance and changes in serum adipocytokine levels. The aim of the current study was to evaluate the effect of phytosomal curcumin on serum adiponectin and leptin levels in patients with NAFLD. Methods: In this randomized double-blind, placebo-controlled trial, 65 eligible patients were randomly allocated into curcumin and placebo recipient groups using a blocked randomized technique. Parameters of weight, height, body mass index (BMI), fasting blood sugar (FBS), lipid profile, aspartate aminotransferase (AST), alanine aminotransferase (ALT), adiponectin, leptin, and the leptin:adiponectin ratio were measured at baseline and eight weeks after intervention. Results: High-density lipoprotein cholesterol (HDL-C) levels increased significantly in the curcumin group compared to the placebo group (p=0.01). Serum adiponectin levels increased significantly (p<0.001) and serum leptin levels decreased significantly (p<0.001) with a decrease in the leptin: adiponectin ratio in the curcumin group compared to the placebo group after 8 weeks of intervention. Conclusions: Non-alcoholic fatty liver disease was associated with changes in serum adipokines levels. Phytosomal curcumin effectively improved leptin and adiponectin levels. It is possible that curcumin efficacy will increase with long-term use of higher doses of this substance.
