Effects of catabolic stress in acute and chronic renal failure.

The degree of catabolism was studied in a group of seven patients with postsurgical acute renal failure, and net protein catabolism of 43.1 to 927 g/day. In 70% of a group of 30 patients with stable chronic renal failure receiving and 18 g high biological value protein diet, urea synthesis was equivalent to what could be accounted for by the protein content of the food. This equivalence was not found in studies in both adults and children who were treated for catabolic chronic renal failure. Data obtained show the superiority of feeding essential amino acids with an adequated caloric supply. The need for studies aimed at adapting the uremic patient to protein depletive mechanisms is strongly stressed.
