Exploratory Study on the Role of the Digestive Microbiota in Adults Living With HIV-1 — MICRACTIVIH  

HIV Clinical Trial

Official title:
Exploratory Study on the Role of the Digestive Microbiota and Bacterial Translocation in the Immune Activation Profile Associated With Insulin Resistance in Male Caucasian Adults Living With HIV-1 on Effective Antiretroviral Therapy.

Clinical Trial Summary

Chronic immune activation present in aviremic people living with HIV under treatment promotes the onset of insulin resistance and metabolic syndrome, paving the way for the comorbidities that are currently the main causes of morbidity. This activation continues despite effective antiretroviral therapy. In the ACTIVIH study (NCT02334943) the analysis of 68 AI markers allowed classification of 120 aviremic PLHIV under treatment for at least 2 years according to 5 different immune activation profiles. Among these 5 profiles, Profile 2 was characterized by high blood pressure figures, high waist sizes, low HDL-cholesterol levels, high triglyceridemia, and especially hyperinsulinemia. Several studies have shown that the digestive microbiota of this population is less rich and less diverse than that of healthy subjects. However, the digestive microbiota and in particular bacterial proteins and metabolites seem to play a key role in immune activation in people living with HIV. Finally, the digestive microbiota has already been shown to have an impact on insulin sensitivity. The study investigators hypothesize that a particular digestive microbiota could promote the appearance of Profile 2. This microbiota could be the cause of digestive dysbiosis leading to intestinal inflammation, digestive permeability and bacterial translocation.
