[The frequency of antibodies against delta virus in patients with HBs positive hepatitis].

Patients with HBsAg-positive hepatitis were screened for antibodies to HDV and HCV. The incidence of anti-HDV was 12.5% in a sample of 265 patients. The values differed appreciably in men and women, patients with chronic and acute hepatitis, narcomaniacs and subjects taking no narcotics. Antibodies to HDV were more incident in anti-HCV-positive than in anti-HCV-negative patients. The age-specific structure of the sampling has been analyzed and the distribution of HDV, HCV, narcomania, and chronic hepatitis markers for age groups has been determined. A high incidence of mixed (double and triple) infections with hepatotropic viruses has been revealed.
