Protecting babies exposed to HIV from serious infections

Developing Interventions for Protecting HIV-Exposed Uninfected Infants against Severe Infections

NIH-funded research University of Colorado Denver · NIH-11166446

This project aims to see if changing gut bacteria and their products can strengthen immune defenses in babies born to mothers with HIV.

What this research studies

If your baby was exposed to HIV before birth but is uninfected, researchers will follow groups of these babies and babies not exposed to HIV and collect blood and stool samples at about 6, 24, and 48 weeks of age. They will measure immune cell function, gene activity, epigenetic markers, blood metabolites, and the gut microbiome using sequencing and metabolomics. The team will compare these data to find specific gut bacteria and metabolites linked to weaker natural killer and T cell responses and then test those links in lab experiments. The goal is to identify dietary or microbiome targets that could be changed to help protect HEU infants from severe infections.

Who could benefit from this research

Good fit: Ideal candidates are infants born to HIV-positive mothers who are confirmed HIV-negative and who can attend study visits around 6, 24, and 48 weeks of age.

Not a fit: Infants who are HIV-infected, older children, or adults would not be eligible and would not directly benefit from this specific project.

Why it matters

Potential benefit: If successful, this work could point to dietary or microbiome-based approaches that reduce severe infections and hospitalizations in HIV-exposed uninfected infants.

How similar studies have performed: Prior research shows the infant gut microbiome influences immune development, but using microbiome- or metabolite-targeted interventions specifically for HIV-exposed uninfected infants is largely untested.
