RESUMO
HIV infection is a global epidemic, with a prevalence of 0.8%. In Latin America, Chile, Brazil and Uruguay are the countries with the highest rates. The transgender population is the most affected (OR of 48.8 compared to the general population). Multiple bio-psycho-social factors explain these issues. The low use of condoms for pressure from the partner, the idea of reaffirmation of gender, the fear to be replaced by a cisgender person, the presence of commercial sex, among others, influence the highest rates of infection. HIV prevention measures have been implemented, but few specifically targeted at transgender people. Pre-exposure prophylaxis (PreP) seems to be a new prevention alternative in this group, and the integration of support units in gender reaffirmation with units that deliver PreP could increase their adherence and coverage. In HIV (+) transgender people there is low adherence to antiretroviral therapy (ART), in part due to the prioritization of hormonal treatment and the fear that ART will alter their hormonalization process. The few data that exist show that hormonalization is not affected by ART, but that some hormonal treatments could lower the levels of certain antiretrovirals. More studies must be done to evaluate the interaction between antiretrovirals and gender affirming hormone therapy.

Resumen La infección por VIH es una epidemia global (prevalencia de 0,8%). En Latinoamérica, Chile, Brasil y Uruguay son los países con mayores índices. Entre las más afectadas están la población transgénero (OR 48,8 respecto a la población general). Múltiples factores bio-psico-sociales explican estas cifras. Bajo uso del preservativo, la idea de reafirmación de género, el temor a ser reemplazadas(os) por personas cisgéneros, presencia de comercio sexual, entre otros, influyen en las mayores tasas de infección. Se han implementado medidas de prevención del VIH, pero pocas dirigidas en específico a personas transgénero. La profilaxis preexposición (PreP) parece ser una nueva alternativa de prevención en este grupo, y la integración de las unidades de apoyo en la reafirmación de género con las unidades que entregan PreP, podrían aumentar su adherencia y cobertura. En las personas transgénero con infección por VIH existe baja adherencia a terapia antirretroviral (TARV), en parte por priorización del tratamiento hormonal y miedo a que la TARV altere su proceso de hormonización. Los pocos datos existentes muestran que la hormonización no se afecta con la mayoría de la TARV, pero algunos tratamientos hormonales podrían disminuir las concentraciones plasmáticas y tisulares de ciertos antirretrovirales. Faltan estudios que evalúen la interacción entre antirretrovirales y tratamiento hormonal de reafirmación de género.
