    Abstract:
    A case of a 29-year-old homosexual male with chronic hepatitis B infection, cryoglobulinemia, and glomerulonephritis is described. The glomerular lesions were not readily classified, but exhibited features consistent with immune complex deposits, in both peripheral loop (predominantly epimembranous) and mesangial sites. Immunofluorescence studies, which included the use of a monoclonal antibody, showed that HBsAg was present in mesangial deposits but not in peripheral loop deposits. Immunoperoxidase studies employing HRP-conjugated anti-HBc and anti-HBe provided evidence that the epimembranous deposits contained HBe. Studies of the patient's serum revealed high titers of HBsAg, low titers of HBeAg, as well as anti-HBe and anti-HBc. The cryoglobulins contained small amounts of HBsAg, HBeAg, and anti-HBc, but anti-HBe and anti-HBs antibodies were not found. The possible mechanisms accounting for accumulation of HBsAg and HBeAg in glomeruli are discussed. In addition, the literature concerning the nature of hepatitis B antigens found in glomerular deposits is reviewed.
