[Effectiveness of the diet therapy program in patients with chronic renal failure].

The authors developed diets 7A and 7B with varying supply of low-protein food for different therapeutic institutions. Sixty-four four patients with chronic renal failure (CRF) received an experimental diet according to an individual program with regard to the stage, the clinical pattern of CRF and the patient's tolerance to protein. The diet was given after the patients had been kept on the control standard, low-protein, and high-caloric diet. After 3 to 10 weeks of the preset dietetic management the patients showed a considerable improvement in the well-being, an increase in the mean body weight accompanied by decreased edema, fat and hypertension. The time course of changes in the laboratory indicators attested to an improvement of nitrous, protein, lipid and carbohydrate metabolism, a decrease in electrolyte abnormalities, acidosis, and anemia. The deficiency of essential amino acids in the blood remained unchanged, but their ratio to replaceable amino acids slightly increased, while loss with urine declined.
