The incidence of autoantibodies to glomerular basement membrane (AGBMA) and neutrophil cytoplasmic antigens (ANCA) in the initial sera of 889 consecutive patients with a suspected diagnosis of rapidly progressive glomerulonephritis, was determined by prospective study. Forty-seven (5%) were positive for AGBMA alone, 246 (28%) were positive for ANCA alone, 576 (65%) had neither autoantibodies while 20 (2%) had both. Clinical and pathological data collected from patients with both autoantibodies suggested the coexistence of anti-glomerular basement membrane disease and systemic vasculitis. Together, assays for AGBMA and ANCA are important in the diagnosis and management of rapidly progressive glomerulonephritis and may help its further classification.
