ABSTRACT
Data on challenges with pre-exposure prophylaxis (PrEP) uptake and adherence among Kenyan gay, bisexual, and other men who have sex with men (GBMSM) are limited. In this mixed-methods sequential explanatory design study, our quantitative phase followed 157 at-risk, HIV-negative GBMSM who accepted PrEP and enrolled in a cohort with 12-month follow-up. Stored dried blood spots collected at two intervals were batch tested for tenofovir diphosphate (TFV-DP) concentrations at study end. Despite high self-reported adherence, only 14.6% of individuals had protective TFV-DP levels at any visit. Protective TFV-DP levels were positively associated with injection drug use and a self-assessed moderate risk of acquiring HIV, and negatively associated with time since enrolment. In our subsequent qualitative phase, an intensive workshop was conducted with the GBMSM community to identify barriers and facilitators to PrEP uptake and adherence. These data revealed numerous challenges with traditional PrEP programs that must be addressed through community collaborations.
RESUMEN La evidencia respecto a desafíos existentes con aceptación y adherencia de la profilaxis previa a la exposición (PrEP) de VIH, entre los hombres homosexuales, bisexuales y otros hombres que tienen sexo con hombres (GBMSM) en Kenia es limitada. Condujimos un estudio de métodos mixtos y diseño explicativo secuencial. En la fase cuantitativa seguimos a 157 GBMSM VIH-negativos en riesgo que aceptaron PrEP y se inscribieron en una cohorte con un seguimiento de 12 meses. Analizamos, por lotes y al final del estudio, gotas de sangre seca recolectada a dos intervalos de tiempo y previamente almacenada, para determinar las concentraciones de difosfato de tenofovir (TFV-DP). A pesar de la alta adherencia autoinformada, solo el 14,6% de las personas tenían niveles protectores de TFV-DP en alguna visita. Los niveles protectores de TFV-DP se asociaron positivamente con el uso de drogas inyectables y un riesgo moderado autoevaluado de contraer el VIH, y negativamente con el tiempo transcurrido desde la inscripción. En la fase cualitativa posterior, conversamos con GBMSM de la comunidad para identificar las barreras y los facilitadores para la concientización, aceptación, adherencia y retención a PrEP. Estos datos revelaron numerosos desafíos con los programas tradicionales de PrEP que deben abordarse mediante colaboraciones comunitarias.
