Understanding how HIV treatment affects gut bacteria

A Prospective Observational Study of the Impact on the Gut Microbiome in HIV-infected Individuals in Manchester, UK, When Switching From One Class of Antiretroviral Drugs or Delivery Method to Another Class or Delivery Method.

Observational University of Manchester · NCT06100211

This study is trying to see how different HIV treatments affect gut bacteria in people living with HIV by looking at their stool samples before and after they change medications.

What this trial studies

This observational study aims to explore the impact of antiretroviral therapy (ART) on the gut microbiome in individuals with HIV. By collecting stool samples from participants before and after switching their ART regimen, researchers hope to gain insights into how different antiretroviral drugs influence gut health. The findings could lead to more personalized treatment options based on individual gut microbiome profiles. This research is crucial as gut health is linked to overall well-being and can affect various health conditions.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with HIV who have been on stable antiretroviral treatment for at least 12 months and are planning to switch their ART regimen.

Not a fit: Patients with a viral load greater than 50 copies/ml blood may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more tailored HIV treatments that improve gut health and overall patient outcomes.

How similar studies have performed: While there has been growing interest in the relationship between HIV and the gut microbiome, this specific approach to studying the effects of ART on gut health is relatively novel.
