Rapid progressive glomerulonephritis: relapse after prolonged remission.
Three patients with epithelial cell crescents and rapid progressive glomerulonephritis (RPGN) had prolonged remission, presumably induced by treatment with maintenance oral prednisone and cyclophosphamide plus plasmapheresis. Patient 1 had anti-glomerular basement membrane-mediated RPGN, patient 2 had an immune complex disease, and patient 3 did not show any immune deposits. After a two-year remission in two patients and a greater than one-year remission in the third patient, renal function deteriorated. Epithelial cell crescents were again demonstratable on repeated renal biopsy specimens in each patient. One patient again received triple therapy, while the other two patients received megadoses of intravenous prednisolone sodium succinate in place of plasmapheresis. Each patient again entered a stable remission. These three cases demonstrate that RPGN may recur after prolonged remission in all three varieties of this syndrome. If the exacerbation is treated promptly, a second remission may be induced.[1]References
