Abstrakt:	Unlabelled: After a short review of the contemporary understanding of amino acid supplementation to low protein diets in patients with uremia we present the results of administration of ketosteril in 20 low-protein-diet patients on such a diet. Material and Methods: Twenty patients (10 men and 10 women) with stable II and III stage chronic renal failure were assigned to a low protein diet (protein up to 40 g/day). Ketosteril (6 tablets a day) were added to the diet. Some of the basic markers of protein metabolism and nitrogen balance were followed. Results: No evidence of deteriorated protein synthesis was found in the therapy thus administered. Serum urea and creatinine values did not change and even tended to decrease. Glomerular filtration was found to increase insignificantly more markedly in the patients with renal failure in the early stages. Conclusions: A low protein diet with increased content of essential amino acids and their keto-analogues does not deteriorate the nitrogen balance of patients with chronic renal failure. By adding essential amino acids and keto-analogues a normal protein metabolism is maintained in spite of the reduce intake of protein substances with the diet. Supplementation of the diet of chronic renal failure patients with essential amino acids and keto-analogues allows a considerable reduction of the protein intake to be achieved which brings about reduction of glomerular hyperfiltration which actually retards the progression of renal failure and improves its short-term prognosis.
