Summary

The objective of this study is to explore the impact of initiation of ART with different regimens in naïve MSM (in the setting of acute and chronic HIV-infection) on the probability of transmission of HIV by mathematical modeling.

Detailed description

The HIV epidemic among men who have sex with men (MSM) continues to expand in low, middle, and high-income countries. The disproportionate HIV disease burden in MSM is explained largely by the high per act and per-partner transmission probability of HIV transmission in receptive anal sex . Current strategies are inadequate to control HIV spread among MSM; much more vigorous prevention efforts are required, including the early initiation of antiretroviral therapy (ART) that has been shown to reduce the rates of sexual transmission of HIV-1 and the adaptation and expanded use of pre-exposure prophylaxis (PrEP) to prevent the acquisition of HIV-1 infection . Initiation of ART with regimens based on integrase strand transfer inhibitors (INSTI) is associated with a faster decline in HIV-RNA load than what is observed with regimens based on non-nucleoside transcriptase inhibitors (nnRTI), and protease inhibitors (PI). The clinical impact of this finding is unknown although clinical anecdotes suggest that it may it may cause a rapid decline in HIV RNA in women presenting with HIV in late pregnancy. The objective of this study is to explore the impact of initiation of ART with different regimens in naïve MSM (in the setting of acute and chronic HIV-infection) on the probability of transmission of HIV by mathematical modeling.
