Long-term prognosis of focal sclerosing glomerulonephritis. An analysis of 250 cases with particular regard to tubulointerstitial changes

Clin Nephrol. 1990 Mar;33(3):115-22.

Abstract

The following results were obtained in a long-term retrospective study including 250 patients with focal sclerosing glomerulonephritis: 1. The renal survival rate (RSR) was 90% at 5 years and 67% at 10 years, the average period of observation being 4.7 years. 2. Univariate analysis revealed that the following morphologic and clinical parameters are associated with an increased risk of terminal renal failure or death due to renal causes: a) Tubulointerstitial changes in the form of interstitial fibrosis, with or without acute renal failure; b) Advanced glomerular lesions; c) Advanced vascular alterations; d) Nephrotic syndrome present at the time of the biopsy; e) Elevated serum creatinine concentration at the time of the biopsy; f) Arterial hypertension at the time of the biopsy; g) Greater age at diagnosis; h) Male sex. 3. Multivariate survivorship analysis showed that tubulointerstitial changes and the presence of nephrotic syndrome at the time of biopsy are the only variables with significant independent predictive value for the outcome. Assessment of these factors thus allows the pathologist to make a relevant statement concerning the probable course and prognosis of the disease at the time of the diagnostic biopsy.
