Study summary

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.

Read the detailed description

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.

What researchers measure

Primary outcomes

  1. Change from baseline in total cholesterol level with the use of combined Lactobacillus acidophilus and Bifidobacterium animalis subsp.lactis capsules at week 8

    Lactobacillus acidophilus and Bifidobacterium animalis subsp.lactis decreases total cholesterol level. Change = (Baseline total cholesterol-Week 8 total cholesterol)

    Time frame: Baseline and Week 8

  2. Change from baseline in Low Density Lipoprotein (LDL) levels with the use of combined Lactobacillus acidophilus and Bifidobacterium animalis subsp.lactis capsules at week 8

    Lactobacillus acidophilus and Bifidobacterium animalis subsp.lactis decreases LDL cholesterol. Change = (Baseline LDL cholesterol values -Week 8 LDL cholesterol values)

    Time frame: Baseline and Week 8

  3. Change from baseline in Triglyceride levels with the use of combined Lactobacillus acidophilus and Bifidobacterium animalis subsp.lactis capsules at week 8

    Lactobacillus acidophilus and Bifidobacterium animalis subsp.lactis decreases triglyceride levels. Change = (Baseline triglyceride values -Week 8 triglyceride values)

    Time frame: Baseline and Week 8

  4. Change from baseline in fasting glucose levels with the use of combined Lactobacillus acidophilus and Bifidobacterium animalis subsp.lactis capsules at week 8

    Lactobacillus acidophilus and Bifidobacterium animalis subsp.lactis decreases fasting blood glucose levels. Change = (Baseline fasting glucose values -Week 8 fasting glucose values)

    Time frame: Baseline and Week 8

  5. Change from baseline in fasting insulin levels with the use of combined Lactobacillus acidophilus and Bifidobacterium animalis subsp.lactis capsules at week 8

    Lactobacillus acidophilus and Bifidobacterium animalis subsp.lactis decreases fasting insulin levels. Change = (Baseline fasting insulin values -Week 8 fasting insulin values)
