Adding STI testing to PrEP services for women

Integrated Female Sexually Transmitted Infection Testing for HIV Epidemic Control through PrEP: The IN-STEP study

NIH-funded research Johns Hopkins University · NIH-11262285

What this research studies

You would be randomly assigned to either routine symptom-based screening alone or screening plus diagnostic testing for chlamydia, gonorrhea, trichomonas, and syphilis. The team will offer point-of-care or lab STI tests, treat any infections found, and connect women to PrEP services. Researchers will follow participants to see whether adding STI testing increases PrEP starts and longer-term PrEP use among women aged 15–39. The work focuses on clinics in high-HIV-burden areas and includes follow-up visits to monitor care and medication use.

Who could benefit from this research

Good fit: Women ages 15–39 who are sexually active and live in or access care in high-HIV-burden communities would be ideal candidates.

Not a fit: People who are already living with HIV, are outside the age range, or are unwilling to consider PrEP or clinic follow-up would not benefit from joining this trial.

Why it matters

Potential benefit: If successful, this approach could help more women at risk start and stay on PrEP, lowering their chance of acquiring HIV.

How similar studies have performed: Research shows curable STIs are markers of future HIV risk, but routinely integrating multiplex cSTI testing into PrEP programs for women is a newer approach with limited prior implementation evidence.
