A case of hepatitis B virus (HBV)-associated membranous nephropathy (MN) is presented in an 18-year-old Korean male, whose renal disease had begun 9 years previously. He was positive for hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) and antibody to hepatitis B core antigen (anti-HBc) in the serum. By immunofluorescence, HBeAg staining was noted in glomerular deposits in association with IgG, C<sub>3</sub> and C<sub>1q</sub>, while neither HBsAg nor HBeAg was found in the glomerular deposits. The presence of glomerular HBeAg staining by FITC-monoclonal anti-HBe F(ab’)<sub>2</sub> fragments has been reported before, but never in non-Japanese patients. The demonstration of HBeAg in both the glomerular deposits and serum in this case supports the causal relationship of HBeAg and HBV-associated MN.
