The Effect of Probiotics on Microbial Translocation and Inflammation in HIV-infected Patients
Objective:
In this study the investigators aim at investigating:
- probiotics ability to modulate the microbiome and microbial translocation,
- if probiotics affect the level of cholesterol, triglycerides as markers of cardiovascular risk factors and
- if a reduction of microbial translocation is associated with a reduction of inflammation in the gastro-intestinal tract.
Design:
The study is a prospective clinical intervention trial of 40 HIV-infected patients.
Method:
The investigator will administer the bacteria Lactobacillus Rhamnosus in capsular form to each patient 2 times a day in 8 weeks. At baseline and at the 8th week of the intervention, the investigators will collect blood samples, feces samples and make a positron emission tomography-magnetic resonance scans.
