Three hundred seventy-nine individuals [137 non-injecting drug using (non-IDU) heterosexuals, 130 homosexual men and 112 IDU] attending the human immunodeficiency virus (HIV) testing program of a sexually transmitted disease (STD) clinic in Rome were studied to estimate the prevalence and to identify the modalities of transmission of human herpesvirus-8 (HHV-8) infection.
Serological analysis was performed by using an immunofluorescence assay able to detect anti-latent and anti-lytic HHV-8 antibodies.
Twelve acquired immunodeficiency syndrome (AIDS) - Kaposi's sarcoma (KS) patients and 94 blood donors were tested as reference population groups.
Anti-lytic antibodies were detected in 185 (48.8%) individuals ; 52 of them (13.7%) also had anti-latent antibodies.
Both anti-lytic and anti-latent antibody prevalence were higher among homosexual men (66.9% and 27.7%, respectively) than among IDU (49.1% and 8.0%, respectively) and non-IDU heterosexuals (31.4% and 5.1%, respectively), and tended to increase with age.
Anti-lytic HHV-8 antibodies were associated with syphilis [odds ratio (OR)=3.81] but not with hepatitis C virus (HCV) seropositivity.
HIV-infected homosexual men were more likely to have HHV-8 antibodies than those who were HIV-negative.
When using anti-latent antibodies the direction of the OR remained the same, although the associations did not often reach statistical significance.
Among AIDS-KS patients, 83.3% had anti-lytic and 66.6% had anti-latent antibodies. (...)
