Gaps in HIV Treatment and Care Cascade Among Men and Transfeminine Persons Who Have Sex with Men in Kenya, Malawi, and South Africa: Findings from the HIV Prevention Trials Network 075 Study (2015-2017).

Improving HIV outcomes for men who have sex with men (MSM) in sub-Saharan Africa requires addressing gaps in the HIV treatment cascade. This study examined these gaps among 71 treatment-naive MSM with HIV in the HIV Prevention Trials Network 075, a 1-year prospective biobehavioral cohort study (2015-2017) across four sub-Saharan African sites. Following a positive diagnosis, 86% of participants sought HIV care. Reasons for not having sought care or delays included a lack of perceived health issues and practical challenges. Most participants (80%) who engaged in care were prescribed antiretroviral therapy (ART). Although self-reported adherence was high, over one-third of those prescribed ART had no detectable antiretroviral drugs (ARVs) at the study's conclusion. ARV detection was significantly associated with study site, higher income, and experienced homophobia. The highest adherence rates were observed at the site offering direct, integrated treatment, underscoring the potential of "one-stop shop" services to mitigate intra-, interpersonal, and structural barriers. Despite a supportive study environment, gaps remain in linking MSM and transfeminine individuals to sustained HIV care and ART adherence. Given the urgency of addressing HIV among these populations, targeted interventions that promote engagement in care and adherence to treatment are critical.
