Abstract

We enrolled 253 HIV-antibody positive heroin addicts without HIV-related disease (n = 81) or with persistent generalized lymphadenopathy (n = 172) in a prospective study to evaluate clinical progression to AIDS related complex (ARC) or AIDS and to identify factors of possible prognostic relevance. Follow-up lasted between 6 and 40 months (median 12 months). According to the non-parametric Cox's model the only significant (P <0.001) prognostic variable was T4+ cell count considered in three classes: > 800/μl (no depletion), 400-800/μl (moderate depletion) and 800/μl or between 400 and 800/μl respectively. The estimated probability of progression to ARC or AIDS was 0.029, 0.056 and 0.172 at one year in subjects with T4+ cell count of >800/μl, 400-800/μl and
