Survival rate of patients with glomerulonephritis.

This is a fourteen-year follow-up study of patients with primary and secondary glomerulonephritis, diagnosed by percutaneous renal biopsy. The survival curves of 271 patients were determined, applying the method described by Cutler 1958. The term "kidney death" was used for the patients who had died or developed end stage renal failure. The five-year survival rates were: 32 for diffuse proliferative glomerulonephritis (chronic), 22 for focal glomerulosclerosis, 30 for membranoproliferative glomerulonephritis, 62 for membranous nephropathy, 90 for focal and mesangioproliferative glomerulonephritis, and 94 for IgA nephropathy. Two diseases of the secondary glomerulonephritis group were analyzed: renal amyloidosis with a survival rate of 8 and lupus nephritis 51.
