Abstract

Venue-based testing may improve screening efforts for HIV and syphilis, thereby reducing transmission. We offered onsite rapid dual HIV and syphilis testing at venues popular among MSM and/or transgender women in Lima, Peru. We used Poisson regression to calculate adjusted prevalence ratios (aPRs) for factors associated with each infection. Most (90.4%) of the 303 participants would test more frequently if testing was available at alternative venues. New cases of HIV (69) and syphilis infection (84) were identified. HIV was associated with recent sex work (aPR 1.11; 95% CI 1.02–1.22), sex with a partner of unknown serostatus (aPR 1.18; 95% CI 1.09–1.27), exclusively receptive anal sex role (aPR 1.16; 95% CI 1.03–1.30) or versatile sex role (aPR 1.17; 95% CI 1.06–1.30) compared to insertive. Syphilis was associated with reporting role versatility (aPR = 2.69; 95% CI 1.52–5.74). Sex work venues had higher syphilis prevalence 47% versus 28% in other venues, p value = 0.012. Venue-based testing may improve case finding.

Resumen

Realizar pruebas en lugares de encuentro puede mejorar la detección del VIH y sífilis, llegando a reducir transmisión. Ofrecíamos pruebas rápidas para sífilis y VIH en lugares populares entre HSH y/o mujeres transgénero en Lima, Perú. Calculamos razones de prevalencia ajustados (aRP) para factores asociados con cada infección usando regresión de Poisson. La mayoría (90.4%) de los 303 participantes realizarían pruebas más frecuentemente si estuvieran disponibles en lugares alternativos. Se identificaron nuevos casos de VIH (69) y sífilis (84). VIH fue asociado con trabajo sexual (aPR = 1.11; IC95% 1.02-1.22), tener una pareja de seroestatus desconocido (aPR = 1.18; IC95% 1.09-1.27), sexo anal exclusivamente receptiva (aPR = 1.16; IC95% 1.03-1.30) o rol sexual versátil (aPR = 1.17; 95% CI 1.06-1.30) en comparación con insertivo. Sífilis fue asociado con versatilidad de rol (aPR = 2.69; IC95% 1.52-5.74). Los lugares de trabajo sexual tuvieron una mayor prevalencia de sífilis 47% en comparación con 28% en otros, valor-p = 0.012. Pruebas en lugares de encuentro pueden mejorar la búsqueda de casos.
