[Rate of progress of chronic renal insufficiency during low-protein diet]

The rate of progress of chronic renal insufficiency (CRI) under conditions of a diet with a moderate protein content and during a free diet was studied in 40 children with tubulointerstitial renal diseases and glomerulonephritis by determining the dependence of reciprocal serum creatinine on the time. A low-protein diet had a positive effect on the rate of CRI progress in children with tubulointerstitial diseases of the kidneys. The prognostic error--the difference between the foretold and the true period of time to the "death of the kidney" was 12% on the average.
