The possibility of developing protein-energy malnutrition poses a serious risk associated with long-term administration of a restrictive low-protein diet. We conducted a randomized prospective study designed to evaluate 36 patients with chronic renal failure in initial malnutrition (BMI 22%, albumin 35 milligrams, WQ 2.02). In 20 of these patients (Group I), low-protein diet was supplemented with ketoanalogs of essential amino acids along with a low-phosphate drink from casein-free protein. The diet of another 16 patients (Group II) was supplemented with a mixture of essential and non-essential amino acids of egg white. Three-month follow-up revealed a statistically significant improvement in selected metabolic parameters (Surea, albumin, WQ, valine HDL-CH cholesterol, SP and SCa), particularly in Group I (p0.01). In group II, the improvement was either not marked (p0.05) or no improvement was seen. Results of the study indicate that patients found to suffer from initial malnutrition require early dietary supplementation including ketoanalogs of essential amino acids and a special protein providing an adequate amount of energy. |
