[Types of hepatitis in parenteral opiate addicts (author's transl)].

Fifty drug addicts with parenteral heroin abuse and tentative diagnosis of acute hepatitis were examined by means of biochemical and serological tests and by liver biopsy. Diagnosis of acute hepatitis was confirmed in 23 patients. 12 patients were examined by liver biopsy a second time 2 months to 18 months later, 3 patients underwent liver biopsy three times. In 80% of the patients markers of hepatitis B (HBsAg, anti-HBs and anti-HBc) were found in the sera. There is some evidence of not only hepatitis B, but also hepatitis non-A, non-B in parenteral drug addicts leading to protracted forms of acute hepatitis and chronic hepatitis.
