title: Proteinuric glomerular disease in adults: cumulative life tables over twenty years.
abstract: Outcome in 425 patients with persistent proteinuria has been assessed over a period of five to 20 years. Nephrotics and non-nephrotics are analysed separately. Clinical and laboratory findings do not correlate with renal histology. Seventy-eight patients had minimal histological lesions and four died (only one in renal failure). Fifty-one patients had endothelial cell proliferation, and 20-year survival was 70 per cent; renal failure occurred within five years in all 17 who progressed, and was independent of nephrotic status. In both membrano-proliferative disease (98 patients) and membranous glomerulopathy (59 patients) 20-year survival was 20 to 30 per cent. Epithelial cell proliferation (85 patients) had the worst prognosis, and survival after 12 years was negligible. In these last three groups decay in survival was almost linear against time and independent of nephrotic status. In focal proliferative disease 20-year survival in nephrotics (31 patients) was only 30 per cent, contrasting with non-nephrotics (23 patients) with 80 per cent survival. Of 105 patients presenting with proteinuria without symptoms, in 30 the proteinuria was postural and biopsies were not done. The other 75 showed a range of histological changes and prognosis similar to the group with symptoms.
