Human herpesvirus-8 (HHV-8) infection of 130 Hungarian HIV-positive individuals with or without Kaposi's sarcoma was investigated from 158 serum and 122 peripheral blood samples using anti-latency-associated nuclear antigen (LANA) indirect immunofluorescence assay (IFA), recombinant orf65 and orfK8.1 antigen enzyme-linked immunosorbent assays (ELISAs), Western blot assays and orf26 specific nested polymerase chain reaction (PCR). The overall prevalence of HHV-8 infection was found to be 31.5% (41/130) among the Hungarian HIV-positive patients. This seroprevalence rate is 7-11-fold higher than that of healthy HIV-negative blood donors in Hungary. The highest prevalence of HHV-8 infection (36.1%, 35/97) was observed in homo- or bisexual patients. Similar to the serologic results, HHV-8 DNA was not always detectable in all serial samples previously shown to be positive for HHV-8 DNA.
