Syphilis Infection Markers Among HIV Positive Individuals In The Mexico City HIV/AIDS Program

espanolObjetivo. Evaluar las prevalencias de marcadores de infec-cion por T. pallidum en personas que viven con VIH y reciben tratamiento antirretroviral en el Programa de VIH/SIDA de la Ciudad de Mexico, asi como sus caracteristicas asociadas. Material y metodos. Se siguio el metodo del algoritmo reverso para el diagnostico de T. pallidum aplicado a 2 383 individuos VIH positivos, quienes contestaron un cuestionario sobre caracteristicas sociodemograficas, practicas sexuales, diagnostico previo de sifilis y tiempo de tratamiento anti-rretroviral. Las variables significativamente asociadas con los marcadores de sifilis se analizaron mediante un modelo de regresion logistica. Resultados. Las prevalencias de marcadores de infeccion “activa o resuelta” y “probable-mente activa” fueron 44.2 y 28.8%, respectivamente. Las caracteristicas asociadas con los marcadores fueron Clinica Especializada Condesa Iztapalapa (CECI), diagnostico previo de infeccion por sifilis, hombres que tienen sexo con hom-bres (HSH) y practicas sexuales receptivas. Conclusiones.Las prevalencias de marcadores de infeccion por T. pallidumfueron altas y estuvieron relacionadas con practicas sexuales especificas y con el diagnostico previo de sifilis, caracteristicas que requieren medidas preventivas dentro del programa. EnglishObjective. The aim of this study is to evaluate the prevalence of T. pallidum infection markers in HIV-positive individuals receiving highly active antiretroviral therapy (ART) in the Mexico City HIV/AIDS Program, as well as predictive characteristics. Materials and methods. The reverse serologic algorithm method was used for the T. pallidum diagnosis, and applied to 2 383 HIV-positive individuals. Sociodemographic characteristics, sexual practices, previous syphilis diagnosis, and length of antiretroviral treatment, were evaluated. Variables significantly associated with syphilis markers were analyzed using a logistic regression model. Results. Prevalence of “active or resolved” and “probable active” infection markers were 44.2 and 28.8%, respectively. Predictive factors were: Clinica Especializada Condesa Iztapalapa (CECI), previous syphilis diagnosis, men in who have sex with men (MSM), and receptive sex practices. Conclusions. The prevalence of T. pallidum infection markers was the highest ever reported in Mexico, and was related to specific sexual practices as well as previous syphilis diagnosis, elements which require preventive measures in the Mexico City HIV/AIDS Program.
