[Variants in the transient deterioration of kidney function in chronic glomerulonephritis].

A transient inhibition of glomerular filtration and/or elevation of blood creatinine were detected in 126 of 296 patients with chronic glomerulonephritis. Some of the patients had 2-4 episodes which occurred more frequently in exacerbations (56.3% of cases), less frequently in cytostatic treatment or in sanatorium. The predominance of nephrotic syndrome and frequent recurrences or hypertension, long-term course in different causes of the disease suggests several pathogenetic variants of nephrotic syndrome. Transient deterioration of renal function does not affect survival, but its emergence in the course of cytostatic treatment or sanatorium treatment worsens the prognosis being related with sclerosis of the renal tissue.
