Human herpesvirus-8 seropositivity and clinical correlations in HIV-1-positive and highly exposed, persistently HIV-seronegative individuals in Greece.

The prevalence of anti-human herpesvirus 8 (HHV-8) antibodies was retrospectively assessed in a cohort of 248 consecutive HIV-1-positive patients followed up in an academic unit in Greece during a 14-year period and in 46 highly exposed, persistently HIV-seronegative (HEPS) individuals. The impact of the initial anti-HHV-8 status on tumorgenesis and mortality was studied. The first available serum sample from the department's pool was tested.
