How gut bacteria and fiber affect heart health in people with HIV

Official title: Gut microbiota-mediated fiber fermentation in HIV-associated cardiovascular disease

Funded at Cedars-Sinai Medical Center · NIH-11070405 · Data updated 2026-11-12

This study is looking at how the bacteria in the gut of people living with HIV might affect heart health, especially how they change the way fiber from food is turned into helpful substances, which could impact blood pressure and heart disease risk.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals living with HIV who are undergoing antiretroviral therapy and may be experiencing cardiovascular issues.

Less likely to help

Patients who are not living with HIV or those who do not have cardiovascular concerns may not benefit from this research.

What this research studies

This research investigates the relationship between gut microbiota and cardiovascular disease in individuals living with HIV. It focuses on how the gut bacteria, which are altered in people receiving antiretroviral therapy, affect the fermentation of dietary fiber into beneficial compounds called short-chain fatty acids (SCFAs). By using advanced models and technologies, the study aims to understand how these changes may contribute to increased blood pressure and cardiovascular risks. The findings could lead to new strategies for managing heart health in this population.

Why it matters

Potential benefit: If successful, this research could lead to improved cardiovascular health and reduced disease risk for people living with HIV.

How similar studies have gone: Previous research has shown promising results in understanding the role of gut microbiota in cardiovascular health, suggesting that this approach may yield valuable insights.
