title: [Infection caused by the human immunodeficiency virus, hepatitis B virus and delta virus in homosexual males].
abstract: Serological markers of hepatitis B (HBV) and human immunodeficiency (HVI) viruses were investigated in the sera of 90 homosexual males. In addition, in HBsAg positive individuals antibodies against delta virus (DV) were also investigated. Forty sera (44.4%) were positive for HBV and HIV, 61 (67.7%) for HBV and 52 (57.7%) for HIV. HBsAg was detected in 8 cases (8.8%), 7 of which had positive anti-HIV sera. In no case infection by DV was detected. These data show the high prevalence of HBV and HIV infection in the study population. They also suggest that the HBsAg carrier status is more common among HIV positive homosexual males and that the investigated homosexual population has not yet been infected by DV.
