[The prognosis of the accelerated progression of chronic glomerulonephritis]

Based on the data of the 20-year follow-up of 146 patients suffering from intracapillary chronic glomerulonephritis (CGN) verified with the aid of nephrobiopsy, the conclusion was made about the necessity of distinguishing rapid-progressing CGN. In such pattern of CGN, chronic renal failure may occur for up to 5 years since the disease onset. A significant relationship was established between the incidence of rapid-progressing CGN and the morphological and clinical types as well as tubulointerstitial alterations. The clinical types included the active and inactive nephritic, nephrotic and nephrotic-hypertonic types. A regressive analysis made according to the Cox method permitted one to establish that the clinical type of CGN is the most reliable factor of predicting rapid-progressing disease.
