[Studies on Hanganutziu-Deicher antibodies in renal diseases].
H-D antibodies which were known as antibodies detectable in patients with serum sickness have recently been detected in renal diseases. We attempted to detect IgG, IgA and IgM antibodies to N-glycolyl GM3, among other H-D antibodies, by ELISA in various renal diseases and found increased IgM antibody in mesangial proliferative glomerulonephritis, membranoproliferative glomerulonephritis, IgA nephropathy, minimal change nephrotic syndrome and Henoch-Schönlein purpura nephritis (HSPN), elevated IgA antibody in IgA nephropathy and HSPN and raised IgG antibody in IgA nephropathy. In 2 cases of IgA nephropathy, there was noted a good correlation between clinical course and anti-N-glycolyl GM3 antibody titers. Measurement by ELISA of IgG antibody to cytomegalovirus (CMV) seemed as one of immune pathogenetic factors of IgA nephropathy showed a high positive rate for this antibody of IgA nephropathy patients and a positive correlation between the antibody and anti-N-glycolyl GM3 antibody. The key molecule of H-D antigens is N-glycolyl neuraminic acid (NGNA) and this sialic acid does not normally exist in humans. One can surmise, therefore, that in those renal diseases in which there was noted an elevation of anti-N-glycolyl GM3 antibody, this antigen is formed or generated by some unknown mechanism. In other words, it may be that humans are not entirely negative for H-D antigens but have a minimum inherent antigenicity and a potential capacity to synthesize these antigens.(ABSTRACT TRUNCATED AT 250 WORDS) Topics: Adolescent; Antibodies, Heterophile; Antibodies, Viral; Child; Child, Preschool; Cytomegalovirus; G(M3) Ganglioside; Glomerulonephritis, IGA; Humans; Kidney Diseases | 1992 |
