Abstract

Background:Probiotics incorporated into dairy products have been shown to reduce total (TC) and LDL cholesterolemia(LDL-C) in subjects with moderate hypercholesterolemia. More specifically, probiotics with high biliary salt hydrolaseactivity, e.g.Bifidobacterium longumBB536, may decrease TC and LDL-C by lowering intestinal cholesterol reabsorptionand, combined with other nutraceuticals, may be useful to manage hypercholesterolemia in subjects with lowcardiovascular (CV) risk. This study was conducted to evaluate the efficacy and safety of a nutraceutical combinationcontainingBifidobacterium longumBB536, red yeast rice (RYR) extract (10 mg/day monacolin K), niacin, coenzyme Q10(Lactoflorene Colesterolo®). The end-points were changes of lipid CV risk markers (LDL-C, TC, non-HDL-cholesterol (HDL-C),triglycerides (TG), apolipoprotein B (ApoB), HDL-C, apolipoprotein AI (ApoAI), lipoprotein(a) (Lp(a), proprotein convertasesubtilisin/kexin type 9 (PCSK9)), and of markers of cholesterol synthesis/absorption.Methods:A 12-week randomized, parallel, double-blind, placebo-controlled study.
