Treating depression to improve gut, immune, and brain health in people with HIV

Treatment Research Investigating Depression Effects on Neuroimmune Targets (TRIDENT)

NIH-funded research Florida International University · NIH-11171469

This project checks whether a targeted cognitive-behavioral therapy for depression can improve gut, immune, and brain-related health in people living with HIV who are on modern antiretroviral therapy.

What this research studies

If you join, you would be randomly assigned to receive an evidence-based Cognitive-Behavioral Therapy for Adherence and Depression (CBT-AD) or a control condition after a short run-in period. The trial plans to enroll 120 people with HIV who have depression and are taking an INSTI-based ART regimen with an undetectable viral load. Researchers will collect stool and blood samples and measure gut microbiome health, markers of gut barrier function and immune activation, and mood and cognitive measures over time. The goal is to see how reducing depression changes connections among the gut, immune system, and brain.

Who could benefit from this research

Good fit: Ideal candidates are adults living with HIV who have current depression, are on an INSTI-based ART regimen with an undetectable viral load, and can attend therapy and study visits.

Not a fit: People without HIV, people who are not experiencing depression, those not on an INSTI-based ART regimen, or those with a detectable viral load may not benefit from the findings or be eligible to participate.

Why it matters

Potential benefit: If successful, this work could lead to behavioral treatments that reduce inflammation and improve gut and mental health for people living with HIV.

How similar studies have performed: Cognitive-behavioral therapies have helped depression and medication adherence in people with HIV before, but using CBT-AD specifically to change microbiome and immune pathways in treated HIV is a new approach.
