A Case of Anti-Glomerular Basement Membrane Antibody Associated Crescentic Glomerulonephritis with Positive Antineutrophilic Cytoplasmic Antibody / 대한신장학회잡지

ABSTRACT

A 63-year-old woman presented to the hospital with gross hematuria and acute renal failure. Kidney function deteriorated rapidly and progressively. A renal biopsy revealed segmental or circumferential crescents associated with linear deposits of immunoglobulin G, typical of anti-glomerular basement membrane disease. Both c-ANCA and anti-GBM antibody were detected in serum. She was treated with hemodialysis, plasmapheresis, high dose steroid and cyclophosphamide. However, she died 7 weeks after treatment because of pneumonia, without recovery of renal function. Serologic positivity of both ANCA and anti-GBM antibody are becoming more frequently recognized in rapidly progressive glomerulonephritis. The influence of c-ANCA on the clinical course of anti-GBM glomerulonephritis remains to be determined.
