Exploring the link between HIV, liver health, and gut bacteria

The Gut, Liver And Metabolome in Human Immunodeficiency Virus and Non Alcoholic Fatty Liver Disease

Early Phase 1 Interventional Vanderbilt University Medical Center · NCT06113003

This study is testing if adding prebiotic and probiotic fiber can help improve liver health in people living with HIV by looking at how gut bacteria might affect liver disease.

What this trial studies

This study investigates the relationship between HIV and non-alcoholic fatty liver disease (NAFLD), focusing on how changes in the intestinal microbiome may contribute to liver disease in individuals with HIV. It aims to determine if supplementation with prebiotic and probiotic fiber can improve liver health markers in these patients. The research will analyze the gut microbiome and its metabolites to understand their role in liver disease progression among people living with HIV. By identifying these connections, the study seeks to provide insights into potential therapeutic interventions.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals living with HIV who also have non-alcoholic fatty liver disease or components of metabolic syndrome.

Not a fit: Patients without HIV or those who do not have metabolic syndrome or NAFLD may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new dietary interventions that improve liver health in individuals with HIV.

How similar studies have performed: While there is limited data on this specific approach, studies have shown that gut microbiome alterations can impact liver health, suggesting potential for success.
