A new study indicated that individuals in a heterosexual HIV-serodiscordant relationship who were using pre-exposure prophylactic drugs (PrEP) to prevent HIV transmission did not increase sexual risk-taking although they knew they were protected.
The researchers, led by Dr. Jared Baeten of the University of Washington, Seattle, conducted a longitudinal study to determine whether an HIV-uninfected man or woman who was protected from HIV transmission through the use of PrEP would exhibit risky sexual behavior. The researchers analyzed data on more than 3,000 participants in the Partners PrEP study. They conducted the analysis for up to 12 months before the efficacy of PrEP was shown in 2011 and 12 months after when participants knew of its protective effects. Participants also received risk-reduction counseling, safety monitoring, pregnancy testing, and gonorrhea, chlamydia, and trichomoniasis testing.
Findings showed that after being informed of the protective effects of PrEP, participants displayed no significant difference in level of unprotected sex between partners.
