What this trial studies

This observational study analyzes the gut microbiota of individuals living with HIV who have maintained virological suppression for at least five years. It aims to investigate the relationship between gut microbiota changes and the development of frailty markers and comorbidities over a five-year period. Participants will undergo stool sampling and blood plasma collection to assess their microbiota and health status. The study focuses on individuals aged 55 and older, who have stable HIV infections and meet specific health criteria.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 55 and older, living with HIV, who have been virologically suppressed for at least five years.

Not a fit: Patients who are currently undergoing treatment that disrupts gut microbiota, such as antibiotics or probiotics, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of frailty in older adults living with HIV.

How similar studies have performed: While the specific approach of this study may be novel, previous studies have indicated a connection between gut microbiota and health outcomes in various populations, suggesting potential for success.
