Dietary management of patients in chronic renal failure

A new oral amino acid preparation was given to two groups of patients: group 1, five patients on hemodialysis; and group 2, five patients with chronic renal failure (CRF). In group 1 significant pre- and postdiet changes were: BUN 93-37 mg% (p smaller than 0.01); creatinine 13.0-9.7 mg% (p smaller than 0.001); phosphorus 6.6-4.2 mg% (p smaller than 0.05); uric acid 8.7-6.0 mg% (p smaller than 0.01); CO2 16.3-21.3 mEq/I (p smaller than 0.01); hematocrit 18.0-20.8% (p smaller than 0.05). In group 2: BUN 93-66 mg% (p smaller than 0.05); phosphorus 5.6-3.8 mg% (p smaller than 0.05); hematocrit 27.3-30.7% (p smaller than 0.05). Nitrogen balance was positive in all patients. It is concluded that this oral amino acid mixture is well-tolerated and can be utilized in CRF to attain protein anabolism.
