Hypercholesterolemia is a main risk factor of cardiovascular disease. Probiotics are a safe approach to reduce elevated cholesterol without any deleterious effect to human health. Saccharomyces boulardii CNCM I-745 probiotic properties are well documented in a context of intestinal dysbiosis. Recent in vitro and preclinical studies have suggested its potential effects on dyslipidemia. This is the first controlled study investigating the effects of S. boulardii CNCM I-745 on lipidemic profile and gut microbiota in a hamster hypercholesterolemic model. Daily administration (3 g/kg) of S. boulardii for 21 or 39 days in hamsters fed a 0.3% cholesterol-diet significantly reduced total plasma cholesterol (P<0.001) and increased faecal total cholesterol (P<0.05) compared to vehicle-treated animals. S. boulardii significantly modified the gut microbiota composition of the hamster fed a 0.3% cholesterol-diet. These microbial abundancy modifications of the microbiota were correlated to variations of lipidemic values or liver genes expressions. In particularly we found that abundance of g_Allobaculum, the most modified taxon after S. boulardii treatment (+236%; P<0.05), was correlated to variations in plasmatic lipoproteins level and ABCG5 hepatic gene expression. We also observed a not previously described correlation between the levels of g_Oxalobacter in the gut microbiota and total cholesterol plasma concentration. In conclusion, we confirmed the cholesterol-lowering effects of S. boulardii intake and we demonstrated for the first time the S. boulardii effect on gut microbiota in the context of hypercholesterolemia in hamsters. Our results provide new insights for a beneficial and safe approach of hypercholesterolemia treatment and could be considered for clinical development, alone or in addition to conventional treatment.
