How alcohol use affects HIV prevention medication adherence and gut health.

Alcohol Misuse, Gut Microbial Dysbiosis and PrEP Care Continuum: Application and Efficacy of SBIRT Intervention

NIH-funded research University of Louisville · NIH-10912467

This study is looking at how drinking alcohol might affect how well PrEP works for preventing HIV and how it can cause side effects that make it harder for people to stick to their medication, and it’s for individuals at risk for HIV who want to understand the best ways to manage their alcohol use while taking PrEP.

What this research studies

This research investigates the relationship between alcohol consumption and the effectiveness of pre-exposure prophylaxis (PrEP) in preventing HIV. It aims to understand how alcohol use may worsen side effects of PrEP, particularly gastrointestinal issues, and how these effects can impact adherence to the medication. The study will explore decision-making processes regarding alcohol and PrEP use among individuals at risk for HIV, and it will evaluate the effectiveness of a specific intervention (SBIRT) designed to reduce hazardous alcohol use and improve PrEP adherence. Participants will be followed over time to assess changes in their alcohol use, gut health, and adherence to PrEP.

Who could benefit from this research

Good fit: Ideal candidates for this research are HIV-negative individuals who are at risk for HIV and currently using or considering PrEP while also consuming alcohol.

Not a fit: Patients who do not consume alcohol or are not at risk for HIV may not receive direct benefits from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for maintaining PrEP adherence among individuals who consume alcohol, ultimately enhancing HIV prevention efforts.

How similar studies have performed: While there is limited research specifically addressing the interaction between alcohol use and PrEP adherence, similar interventions have shown promise in improving substance use outcomes in other populations.
