Abstract
We investigated the rate and predictors of ineffective HIV protection in men who have sex with men (MSM) taking pre-exposure prophylaxis (PrEP) in a prospective cohort study from November 2017 to November 2020 in Mali, Côte d’Ivoire, Burkina Faso, and Togo. MSM had to be 18 years or older and at high risk of HIV infection to participate. They also received a comprehensive sexual health prevention package, including PrEP, in community-based clinics as part of the cohort study. Using socio-behavioral/clinical data, HIV protection during their most recent anal intercourse with a male partner was categorized as effective or ineffective (i.e., incorrect PrEP adherence and no condom use). Seventeen percent (500/2839) of intercourses were ineffectively protected for the 520 study participants. Predictors of ineffective HIV protection included being an event-driven user with financial difficulties, having a high alcohol misuse score, and not being a member of a community association. PrEP programs in West Africa must be tailored to socially vulnerable MSM who struggle to adopt PrEP.
Resumen
En este artículo hemos investigado la proporción y los factores predictivos de la protección ineficaz de VIH en un grupo de hombres, que tienen sexo con hombres (HSH) y que usan la profilaxis pre-exposición (PrEP). Se usaron los datos de un estudio de cohorte prospectivo realizado entre noviembre del 2017 y noviembre del 2020 en Mali, Costa de Marfil, Burkina Faso y Togo. Los participantes son HSH, de 18 años o más, y con alto riesgo de contaminación por el VIH. Estos han recibido un paquete completo de prevención en salud sexual incluyendo la PrEP en clínicas comunitarias como parte del estudio de cohorte. La protección contra el VIH durante la última relación sexual anal con un hombre fue categorizada como eficaz o ineficaz a partir de datos socio-comportamentales/clínicos (i.e. adhesión incorrecta à la PrEP y no utilización del condón). Concerniente a 520 participantes, 17% (500/2839) de las relaciones sexuales fueron protegidas de manera ineficaz. Entre los factores predictivos de la protección ineficaz contra el VIH se encuentran, el uso intermitente de la PrEP asociado a una situación financiera difícil, el consumo de alcohol y no ser miembro de una asociación comunitaria. Los programas de PrEP en África del Oeste, deben adaptarse a los HSH más vulnerables quienes podrían tener más dificultad para adoptar la PrEP.
