Recurrence of ANCA-positive glomerulonephritis immediately after renal transplantation.

Recurrence of crescentic necrotizing glomerulonephritis after renal transplantation is rare. Successful renal transplantation in patients with antineutrophil cytoplasmic autoantibody (ANCA) glomerulonephritis has been reported. The presence of ANCA at transplantation does not appear to increase the rate of relapse after kidney allografting. Therapy with cyclophosphamide and corticoids usually is effective. We report a case of recurrent perinuclear ANCA crescentic necrotizing glomerulonephritis immediately after renal transplantation that was treated successfully by cyclophosphamide, plasma exchange, and intravenous polyvalent immunoglobulin.
