title: Circulating HBsAg/IgG complexes in idiopathic chronic glomerulonephritis.
abstract: We measured HBsAg/IgG complexes (CX) quantitatively by ELISA from HBsAg positive serum of 35 liver disease patients, 15 patients with glomerular diseases (8 membranous glomerulonephritis (MGN) 7 membranoproliferative glomerulonephritis (MPGN), and 50 healthy carriers of HBsAg. HbsAg/IgG CX was detected in 26 out of 35 liver disease patients (74.3%), 5 out of 50 healthy carriers (10%), and one of both 8 MGN patients (12.5%) and 7 MPGN patients (14.3%). HBsAg/IgG CX was big in size and wide spread in the liver disease groups but negligible in the healthy carrier group (41 +/- 2.6 ng/ml, n = 5) and MGN (50 ng/ml, n = 1) and MPGN (42 ng/ml, n = 1) group. In the liver disease group, no one suffered from glomerulopathy even with a wide spectrum of HBsAg/IgG CX. These results suggest that HBsAg/IgG CX in plasma is non causative of MGN and MPGN.
