To find out predictive value of three factors in progression of chronic glomerulonephritis (CGN): unfavorable clinical course, unfavorable morphological type and tubulointerstitial changes.
150 CGN patients entered the trial. Frequency of onset of chronic renal failure (CRF) within 7 years after the diagnosis was chosen as a criterium of accelerated progression of CGN (AP CGN). Chi-square criterium was used for testing relationships between AP CGN and the parameters under study.
The findings support previously published data on statistically more frequent occurrence of AP CGN in unfavorable clinical types (active nephritic and nephrotically-hypertensive), in unfavorable morphological types (mesangiocapillary CGN and focal-segmental hyalinosis/sclerosis and tubulointerstitial lesions). In unfavorable clinical types there was a significantly more frequent occurrence of AP CGN irrespective of unfavorable morphological changes. In contrast, both in unfavorable and favorable clinical types, frequency of AP CGN in unfavorable morphological types of CGN and tubulointerstitial changes was the same.
Clinical type of CGN is a valuable prognostic criterium for AP CGN.
