Abstract
The prevalence of hepatitis A-, B- and C-markers has been studied in patients at a Norwegian rehabilitation centre for drug addicts. The prevalence of hepatitis C-antibodies was fairly constant in the years 1976 (56%), 1985 (78%) and 1988-89 (73%), but may be decreasing in younger addicts. The data suggest a highly variable incidence of HAV with few infections in recent years. The prevalence of hepatitis B-markers, which has been calculated from 1975 to 1988-89, reached a maximum of 93% in 1986. Since then a significant decrease in prevalence has been observed among younger patients, suggesting that the HIV campaign has led to improved hygiene precautions among intravenous drug addicts. A strong correlation was observed between positive markers for HBV and presence of anti-HCV, and, similarly, between the presence of anti-HAV and markers for HBV and HCV. Anti-HCV was significantly associated with pathological ALT-values.
