[Clinical and morphologic predictors of the progress of chronic glomerulonephritis].

Observation over 183 patients with a morphologically verified diagnosis of chronic glomerulonephritis (CGN) made it possible to establish on a mathematic basis a highly significant relationship between the disease progress and the clinical and morphological disease patterns. In the active nephritic patterns and in the nephrotic-hypertonic pattern, chronic renal failure (CRF) occurred in the majority of the patients within the first 5 years. Meanwhile in the inactive nephritic pattern and in the nephrotic pattern, a corticoid-sensitive one, characterized by the phasic course, CRF could not almost be seen over up to 20 years after the disease onset. As far as the morphological patterns are concerned, focal-segmental glomerular hyalinosis/sclerosis turned out most unfavourable. In patients with this pattern, CRF was diagnosed during 5 years in almost half of the patients. The mesangio proliferative and membranous patterns appeared most favourable. The incidence of CRF during 5 years after the disease onset, common to the definite clinical patterns, did not depend on the concomitant morphological pattern. Provided there were sclerotic lesions throughout 2 years after the disease onset, CRF occurred in 65% of the cases for 10 years, whereas with their lack in 9% of the cases. The most important predictors of CRF were as follows: the clinical pattern of CGN and the presence of sclerotic lesions in the renal biopsy specimen. Of definite significance might be the morphological pattern of CGN.
