Influence of protein intake and renal function on plasma amino acids in patients with renal impairment and after kidney transplantation.
A group of 17 patients with chronic renal impairment and a group of 11 patients surviving for 3--7 years after kidney transplantation were examined. In all patients plasma amino acids were analyzed. The ratio of essential/nonessential amino acids, the valine/glycine ratio and Whitehead's quotient are influenced above all by the dietary protein intake. Raised citrulline and 3-methylhistidine values were not influenced by the protein intake, while they correlate with indicators of renal function. Changes detected after kidney transplantation are analogous.
