    BackgroundType 2 diabetes (T2D) is an established risk factor for cardiovascular disease (CVD) and is associated with disturbed metabolism of lipids and lipoproteins. Curcuminoids are natural products with anti-diabetic and lipid-modifying actions but their efficacy in improving dyslipidemia in diabetic individuals has not been sufficiently studied.ObjectiveTo investigate the efficacy of supplementation with curcuminoids, plus piperine as an absorption enhancer, in improving serum lipids in patients with T2D.MethodsIn this 12-week randomized double-blind placebo-controlled trial, subjects with T2D (n=118) were assigned to curcuminoids (1000mg/day plus piperine 10mg/day) or placebo plus standard of care for T2D. Serum concentrations of lipids including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), lipoprotein(a) [Lp(a)], and non-HDL-C were determined at baseline and at the end of trial.ResultsBetween-group comparison of change in the study parameters revealed significant reductions in serum levels of TC (-21.86±25.78 versus -17.06±41.51, respectively; p=0.023), non-HDL-C (-23.42±25.13 versus -16.84±41.42, respectively; p=0.014) and Lp(a) (-1.50±1.61 versus -0.34±1.73, respectively; p=0.001) and elevations in serum HDL-C levels (1.56±4.25 versus -0.22±4.62, respectively; p=0.048) in the curcuminoids group as compared with the placebo group (p<0.05). Serum TG and LDL-C changes did not show any significant difference between the study groups (p>0.05).ConclusionCurcuminoids supplementation can reduce serum levels of atherogenic lipid indices including non-HDL-C and Lp(a). Therefore, curcuminoids supplementation could contribute to a reduced risk of cardiovascular events in dyslipidemic patients with T2D.Copyright © 2017 Elsevier Ltd. All rights reserved.
