What this trial studies

This randomized control trial focuses on individuals using pre-exposure prophylaxis (PrEP) to evaluate the effectiveness of Screening, Brief Intervention, and Referral to Treatment (SBIRT) in mitigating hazardous alcohol use. The study aims to understand how alcohol consumption affects PrEP adherence and the gut microbiome, as well as to assess the impact of early intervention on these factors. Participants will attend multiple visits over a year, where they will engage in surveys, interviews, and provide biological samples to analyze changes in gut health and inflammation related to alcohol use. The research employs a syndemic approach to enhance HIV prevention strategies among populations affected by alcohol misuse.

Who should consider this trial

Good fit: Ideal candidates for this study are English or Spanish-speaking adults aged 18-85 who are seronegative for HIV, Hep B, and Hep C, and currently using PrEP.

Not a fit: Patients with major psychiatric illnesses, unstable medical conditions, or severe gastrointestinal/liver diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve PrEP adherence and health outcomes for individuals at risk of HIV by reducing alcohol misuse.

How similar studies have performed: Other studies have shown promise in using SBIRT interventions for alcohol misuse, suggesting potential for success in this approach.
