Gut health and HIV: how the gut barrier and microbiome affect metabolic health in HIV-positive men who have sex with men
Official title: Gut microbiome effects on intestinal barrier function and metabolic syndrome in HIV positive men who have sex with men
Funded at University of Colorado Denver · NIH-11377104 · Data updated 2026-11-12
A research grant is exploring how the gut bacteria and gut barrier may influence metabolic problems in HIV-positive MSM, with the goal of finding ways to reduce obesity and heart-disease risk.

Who could benefit from this research
✓Could help
Ideal candidates include HIV-positive men who have sex with men who may have or be at risk for metabolic syndrome.
✕Less likely to help
Patients without HIV or MSM identity, or those not experiencing metabolic risk factors, may derive less direct benefit.
What this research studies
This program studies how the gut microbiome and the intestinal barrier relate to metabolic syndrome in HIV-positive and HIV-negative men who have sex with men. It builds on prior findings showing that gut-derived inflammation and bacterial products may drive metabolic problems, and it aims to uncover the mechanisms linking barrier integrity, microbiome signals, and metabolic risk. Using samples from participants and advanced analyses, researchers will examine markers like LBP and other inflammatory and microbial indicators to understand their roles in metabolic health. The goal is to identify potential targets to improve metabolic outcomes for people living with HIV and MSM communities.
Why it matters
Potential benefit: If successful, the work could lead to new strategies to prevent or reduce metabolic syndrome and related cardiovascular risk in HIV-positive individuals.
How similar studies have gone: Previous research suggests a link between gut inflammation, barrier dysfunction, and metabolic risk, supporting further investigation in HIV-related populations.
