  • Title: Immune complexes in hepatocytic nuclei of HB ag-positive chronic hepatitis.
    Author: Gerber MA, Sarno E, Vernace SJ.
    Journal: N Engl J Med; 1976 Apr 22; 294(17):922-5. PubMed ID: 768764.
    Abstract:
    To localize immune complexes in viral hepatitis Type B and to assess their pathogenic role, we examined by the direct fluorescent-antibody technic 21 liver specimens with hepatitis B core antigen (HBc Ag) in hepatocytic nuclei from 10 patients with HBs Ag-seropositive acute viral hepatitis and from 11 patients with HBs Ag-seropositive chronic active hepatitis. IgG with in vitro fixation of complement was demonstrated in HBc Ag-containing hepatocytic nuclei of all patients with chronic active, but not in those with acute viral hepatitis. All patients except for one had antibody to HBc Ag in the serum as determined by indirect immunofluorescence. The evidence suggests that intranuclear IgG in chronic active hepatitis has anti-HBc specificity and forms immune complexes with HBc Ag. The binding of IgG to intranuclear HBc Ag might have pathogenic importance in chronic active hepatitis.
