[Changes in the filtration function of the kidneys during the treatment of chronic glomerulonephritis].

The implications of the treatment variant and chronic glomerulonephritis (CGN) characteristics in the changes of renal function were evaluated by 220 treatment courses for CGN aggravation. A number of statistical methods were employed. In CGN patients free of renal insufficiency glomerular filtration was either unaffected or recovered after transitory decline. In chronic failure further creatinine clearance diminution was observed, serum creatinine levels went up. Corticosteroid treatment was much safer for the kidneys than cytostatics. With increasing duration of CGN, functional affection of the kidney becomes more frequent irrespective of the treatment kind. The same is true for the number of exacerbation and hypertension which are also involved in renal functional decline.
