title: [Long-term administration of a low-protein diet with keto-analogs of essential amino acids and the metabolic status of patients with chronic kidney failure].
abstract: To 12 patients with chronic renal failure (CHRI) for 12-22 months a diet containing 20 g high quality protein supplemented by keto analogues of essential amino acids (KA)--4.8 g/day--was administered. During the investigation period no significant change of the albumin, prealbumin or transferrin level was recorded, nor of Whitehead's quotient, immunoglobulin levels and haemoglobin concentration, serum iron and its binding capacity. However, there was decline of the C3 complement component (p less than 0.01). The investigated parameters of carbohydrate metabolism (fasting blood sugar, immunoreactive insulin, oral glucose tolerance test) did not change, similarly as total cholesterol and triglyceride levels. The originally reduced HDL-cholesterol level increased (p less than 0.05). The achieved results suggest that the long-term administration of a diet with 20 g protein supplemented by the minimal necessary dose of KA does not produce undesirable changes of the investigated metabolic parameters.
