    Abstract:
    Immune deposit glomerulonephritis has been associated with hepatitis B antigenemia. Immune complexes of this antigen and its antibody have been implicated in the pathogenesis of the renal disease. A boy had acute immune complex disease with glomerulitis in which cryoprecipitable complexes of HbsAg and its antibody were isolated from serum. HbsAg was concentrated in the cryoprecipitate and localized in a granular pattern along the glomerular basement membrane in association with immunoglobulins. Glomerular fixed antibody was eluted and shown to be directed against HbsAg. The level of antibody activity to HbsAg was higher in the eluate than the serum, suggesting immunopathogenic specificity of the antibody. The study demonstrates that the nephritis was mediated by immune complexes of HbsAg and its antibody, and the presence of immunoglobulin on the kidney did not represent trapping from the circulation.
