Sexual activity and Kaposi's sarcoma among human immunodeficiency virus type 1 and human herpesvirus type 8-coinfected men.

Purpose: There is notable heterogeneity in the progression to Kaposi's sarcoma (KS) among men coinfected with HIV-1 and human herpesvirus type 8 (HHV-8); additional determinants of KS likely exist. Here, we explore sexual activity as a proxy for a sexually transmitted determinant beyond HIV-1 and HHV-8.

Methods: The association between sexual activity and incident KS was estimated with data from 1354 HIV-1- and HHV-8-coinfected homosexual men who were followed for up to 10 years in the Multicenter AIDS Cohort Study.
