Effectiveness of Plasmapheresis in a Patient with Anti-glomerular Basement Membrane Antibody Glomerulonephritis with Advanced Kidney Dysfunction

Patients with anti-glomerular basement membrane antibody glomerulonephritis (anti-GBM GN) have severe kidney dysfunction, leading to end-stage renal disease. The effect of plasmapheresis and immunosuppressive treatment in patients with severe glomerular changes is controversial. A 62-year-old man was admitted with rapidly progressive glomerulonephritis and diagnosed with anti-GBM GN. He required hemodialysis. All glomeruli in the kidney biopsy specimen had cellular crescents without fibrotic changes, suggesting reversible damage. He was treated with plasmapheresis until the anti-glomerular basement membrane antibodies disappeared. His kidney function recovered, and dialysis was able to be discontinued. Frequent plasmapheresis in patients with dialysis-dependent anti-GBM GN may improve the kidney prognosis.
