Abstract

Background and aims: This study evaluated the triglyceride (TG)-lowering effects of consuming dual probiotic strains of Lactobacillus curvatus (. L. curvatus) HY7601 and Lactobacillus plantarum (. L. plantarum) KY1032 on the fasting plasma metabolome. Methods and results: A randomized, double-blind, placebo-controlled study was conducted on 92 participants with hypertriglyceridemia but without diabetes. Over a 12-week testing period, the probiotic group consumed 2g of powder containing 5×109colony-forming units (cfu) of L. curvatus HY7601 and 5×109cfu of L. plantarum KY1032 each day, whereas the placebo group consumed the same product without probiotics. Fasting plasma metabolomes were profiled using UPLC-LTQ-Orbitrap MS. After 12 weeks of treatment, the probiotic group displayed a 20% reduction (p=0.001) in serum TGs and 25% increases (p=0.001) in apolipoprotein A-V (apoA-V). At the 12-week follow-up assessment, the following 11 plasma metabolites were significantly reduced in the probiotic group than the placebo group: palmitoleamide, palmitic amide, oleamide, and lysophosphatidyl choline (lysoPC) containing C14:0, C16:1, C16:0, C17:0, C18:3, C18:2, C18:1, and C20:3. In the probiotic group, changes (Δ) in TG were negatively correlated with Δ apoA-V, which was positively correlated with Δ FFA. In addition, Δ FFA was strongly and positively correlated with Δ lysoPCs in the probiotic group but not the placebo group. Conclusions: The triglyceride-lowering effects of probiotic supplementation, partly through elevated apoA-V, in borderline to moderate hypertriglyceridemic subjects showed reductions in plasma metabolites, fatty acid primary amides and lysoPCs (.
