[Markers of HBV infection in drug addicts]

Abstract

Prevalence of markers of HBV infection was tested in two cohorts of drug addicts: in 140 addicts whose sera were drawn in the years 1985-1986 and in 100 addicts whose sera were drawn in the years 1988-1989. HBsAg was found in 10 (7%) patients in the earlier cohort and in 12 (12%) addicts in the latter, while at least one marker of HBV infection was present in 39% and 69%, respectively No correlation was found between the presence of markers of HBV infection and age, gender, or HIV status, however, duration of drug abuse increased the risk of HBV infection. There was no difference in mean titres of anti-CMV and anti-HSV-1 between subjects with and without HBV markers what suggests that the tested markers were specific.
