The role of pharmacomicrobiomics in HIV prevention, treatment, and women’s health

In the absence of an effective vaccine or curative treatment for HIV, the global HIV/AIDS epidemic continues despite significant advances in treatment and prevention. Antiretroviral therapy (ART) drugs have transformed HIV from a terminal illness to a manageable chronic condition. Likewise, pre-exposure prophylaxis treatment (PrEP) has dramatically reduced transmission in some of the highest risk populations. However, quality of life and life expectancy in people living with HIV (PWH) still lag significantly behind the general population. The mechanisms that reduce the efficacy of PrEP and ART are multifaceted, but one factor that warrants additional attention is the impact of the microbiome on ART and PrEP efficacy, as well as pharmacokinetics more broadly. In this review, we assess the current state of research on the HIV-associated microbiome, how this impacts treatment efficacy, and how microbiome states can alter HIV susceptibility. We also explore how the mechanisms we propose could extend to the efficacy of other drugs and identify promising areas of research that remain understudied.
