Profilaxia pré-exposição a VIH

Profilaxia pré-exposição a VIH

Abstract

A profilaxia pré-exposição a VIH (PrEP) consiste na utilização de fármacos antirretrovirais para prevenir a infeção por VIH em indivíduos suscetíveis. A combinação emtricitabina-tenofovir por via oral em toma diária ou intermitente é eficaz mas dispendiosa, e não substitui o preservativo na prevenção de outras infeções sexualmente transmissíveis. Em subpopulações de risco muito elevado, a PrEP é custo-efetiva, como é o caso de homens que têm relações sexuais com homens nos países desenvolvidos ou de mulheres jovens na África subsariana. Neste artigo de revisão da literatura pretende-se abordar, de uma forma generalista, os ensaios clínicos e restantes evidências científicas relacionadas com a PrEP, normas de orientação clínica, resultados já disponíveis da prática clínica e previsões quanto ao seu impacto epidemiológico. Por fim, será apresentada uma proposta para a utilização da PrEP em Portugal.

Preexposure HIV prophylaxis (PrEP) consists of using antiretroviral drugs to prevent HIV infection on susceptible individuals. Emtricitabine-tenofovir per os daily or on demand is effective but also expensive and it does not replace condoms on the prevention of other sexually transmitted infections. In higher risk subpopulations PrEP is cost-effective, such as men who have sex with men in developed countries or young women in sub-Saharan Africa. This paper aims to review literature on PrEP, such as the clinical trials and other scientific evidence, clinical guidelines, results from clinical practice and perspectives regarding its epidemiological impact. At last, a proposal regarding PrEP use in Portugal will be discussed.
