Characterization of Patients at High Risk for the Acquisition of Sexually Transmitted Infection With HIV - a Clinical Study

What this Trial Is About

This research aims to understand how new HIV infections occur among people at high risk due to their sexual behaviors. It focuses on individuals who are HIV-negative men who have sex with men (MSM) and transgender people, particularly those who engage in unsafe sex, have recently had a sexually transmitted infection (STI), used post-exposure prophylaxis (PEP), or frequently participate in 'chemsex'. The study is observational and conducted by the Medical University of Vienna to provide insights into HIV transmission and related infections. Participants will be observed over a period of up to 10 years without receiving any treatment as part of the study. Researchers will collect important clinical information related to sexual behaviors, use of HIV pre-exposure prophylaxis, and occurrence of other STIs. Laboratory tests will be performed on blood, urine, and mucosal samples to monitor infections and related health factors. During the study, participants will provide medical history and behavioral information through assessments. Researchers will monitor the incidence of new HIV infections and other sexually transmitted infections throughout the study period. The study involves regular collection of samples and clinical data, with safety and well-being monitored as part of the observational process.
