Effect of Different Probiotic Strains in Hypercholesterolemic Patients

A Randomized Double-Blind Controlled Trial of Lactobacillus Acidophilus Plus Bifidobacterium Animalis Subsp.Lactis, Versus Lactobacillus Rhamnosus GG Versus Placebo in Patients With Hypercholesterolemia

Regular probiotic use for 8 weeks was evaluated in individual with mild to moderate hyperlipidemia. Current study have been determined the use of different probiotics strains on lipid parameters such as; total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride levels as well as glycemic parameters such as; glucose, insulin, HOMA-IR levels. Also, hs-CRP levels were investigated as inflammatory parameter.

In the light of recent studies, it has been shown that probiotics may have positive effects on hyperlipidemia. The aim of this study was to investigate the effect of probiotics mainly on blood lipids as well as homocysteine levels, glycemic control parameters and hs-CRP levels A randomized, double-blind placebo-controlled study was completed with a total of 51 individuals who have diagnosed with hyperlipidemia. Participants were randomly assigned into 3 groups according to the probiotic type they would consume, groups were as follows; Lactobacillus (probiotic group I) (n=18), Lactobacillus and Bifidobacterium (probiotic group II) (n=17) and placebo group (n= 16). They were all requested to have placebo or probiotic capsules every day for 8 weeks. Total cholesterol, HDL cholesterol, LDL cholesterol, triglyceride levels were investigated as lipid metabolism parameters while fasting blood glucose, insulin, HOMA-IR levels were investigated as glycemic parameters. Also, hs-CRP levels were investigated as inflammatory parameter.

Participants recevied a combined Lactobacillus acidophilus 1x109 cfu and Bifidobacterium animalis subsp.lactis 1x109 cfu once a day for 8 weeks.

Placebo capsules usually do not improve total cholesterol. Change = (Baseline total cholesterol values - Week 8 total cholesterol values)

Placebo capsules usually do not improve LDL cholesterol. Change = (Baseline LDL cholesterol values - Week 8 LDL cholesterol values)

Placebo capsules usually do not improve triglyceride levels. Change = (Baseline triglyceride values - Week 8 total triglyceride values)

Placebo capsules usually do not improve fasting glucose levels. Change = (Baseline fasting glucose values - Week 8 total fasting glucose values)

Placebo capsules usually do not improve fasting insulin levels. Change = (Baseline fasting insulin values - Week 8 fasting insulin values)
