Abstract
BACKGROUND The effect of antiretroviral therapy on seminal HIV shedding in the community remains unknown. OBJECTIVE To evaluate the effect of antiretroviral therapy on HIV shedding in semen. DESIGN Prospective cohort study. SETTING University hospital in Rio de Janeiro, Brazil. PATIENTS 93 HIV-infected men. INTERVENTION Antiretroviral therapy as prescribed by each patient's physician. MEASUREMENT HIV RNA in semen and blood plasma before and after introduction of therapy. RESULTS At baseline, HIV RNA was detected in 69 semen samples (74%) and 89 blood samples (96%). Six months after introduction of therapy, HIV RNA was detected in 29 semen samples (33%) and 33 blood samples (38%). The mean reduction in levels of HIV RNA in semen at 6 months was 1.65 log10 units. CONCLUSIONS Antiretroviral therapy reduces shedding of HIV in semen, which probably in tum reduces HIV transmissibility. However, a substantial proportion of patients may still be infectious and may have drug-resistant strains of the virus.
