Nitrogen balance in uremic patients on different amino acid and keto acid formulations--a proposed reference pattern.

Nitrogen balance was studied in 12 uremic patients given nitrogen intakes in varying formulations, either solely as amino acids or as keto acid and amino acid mixtures. It was shown that of the three formulas studied, the one that was most effective in promoting positive balance was the one having threonine as reference unit, with a relatively high tyrosine intake and lower methionine content, and histidine in the proportions found in human milk and in the egg pattern. Also, in all instances in which an amino acid formulation caused a deviation in nitrogen balance, the same effect was obtained with formulations containing keto acids. However, the effect with the keto acids was less pronounced.

Lysine in treatment of hyperornithinemia.

A metabolic study in a case of hyperornithinemia with gyrate atrophy of choroid and retina is presented. It is demonstrated that the lysine-ornithine antagonism is a physiological, safe, easy to handle therapeutic tool in hyperornithinemia. A lysine load was invariably associated with a reduction of plasma ornithine concentration. This happened at any level of protein intake. It was also shown that diets containing a low protein intake are invariably associated with negative nitrogen balance.

Anabolic agents in kidney disease: the effect of formebolone on protein synthesis in patients with renal insufficiency or nephrosis.

The anabolic activity of formebolone was studied in 7 patients with nephrosis or renal insufficiency by measuring the amount of 14C-leucine incorporated into plasma proteins as an index of protein synthesis. The data demonstrate that the incorporation of label into the plasma albumin fraction was significantly increased after formebolone administration.

Urea index and nitrogen balance in uremic patients on miminal nitrogen intakes.

Normal anduremic subjects were studied on different protein intakes. The uremic patients were also given minimal amounts of nitrogen in the form of 8 essential amino acids, with or without the addition of histidine. It was noticed that as little as 416 mg of essential amino acid nitrogen was sufficient to cover body needs if enough non-essential nitrogen was present. It was also demonstrated that on low-nitrogen intakes, the ratio of urinary urea to total urinary nitrogen varied with nitrogen balance.
