[Delta infection in patients with chronic viral hepatitis B].

The results of examination for anti-delta antibodies in the blood of 86 patients (33 children and 53 adults) with chronic persisting hepatitis (CPH) and chronic active hepatitis (CAH) verified by morphological examinations of liver biopsy specimens are presented. Delta infection was found in 43 (31.5%) of patients with CAH, only anti-HBe being demonstrable in the blood.
