A long-term study of hepatitis B virus-related antigens and immunological parameters in children with chronic hepatitis

Forty-two children with HBsAg positive chronic hepatitis who received immunosuppressive therapy underwent multiple liver biopsies over periods ranging from one to five years. The presence of HBsAg, HBcAg, deltaAg, antinuclear antibodies and immune complexes was studied using immunofluorescent techni...

Description
Summary:Forty-two children with HBsAg positive chronic hepatitis who received immunosuppressive therapy underwent multiple liver biopsies over periods ranging from one to five years. The presence of HBsAg, HBcAg, deltaAg, antinuclear antibodies and immune complexes was studied using immunofluorescent techniques. The data were correlated with the clinical status of the patients. The presence of HBsAg, HBcAg and deltaAg remained unchanged throughout the study in most positive patients. All 30 HBcAg positive cases were still positive at the end of the study. One of the negative cases became positive. Eight of the ten delta antigen positive cases showed no change. Intrahepatic immunoglobulins, immune complexes and antinuclear antibodies showed a decrease in positivity in a significant number of patients. Fifteen of the 36 patients positive for intrahepatic immunoglobulins became negative during the study, as did 12 of the 29 immune complex positive subjects and 22 of the 33 antinuclear antibody-positive cases. The persistence of HBV antigens seems to be independent of the clinical course. On the other hand, the persistence of positive immunological indices corresponds to a less favourable outcome.
