Abstract

Immunologic markers associated with hepatitis B virus (HBV) infection (HBsAg, anti‐HBs, HBeAg, anti‐HBe, anti‐HBc, anti‐δ) were tested by radioimmunoassay of serum from chronic hepatitis patients. The corresponding liver biopsy samples were examined for the presence of HBsAg, HBcAg, and δ antigen in the cells by direct immunofluorescence and by electron microscopy. Seventy patients were selected for the presence of both circulating HBsAg and anti‐HBc. Comparison of chronic persistent (CPH) and chronic active (CAH) hepatitis showed a significantly greater frequency of intracytoplasmic HBsAg in CPH, especially in the absence of intranuclear HBsAg, and a greater frequency of intranuclear δ antigen and/or circulating anti‐5 in CAH. The δ/anti‐δ system was almost systematically associated with serum anti‐HBe. At variance with HBeAg/anti‐HBe, δ/anti‐δ was found significantly more frequently in patients originating from Southern rather than from Northern or Central Italy. The prevalence of both these immunologic systems was related to the age of the patients.
