title: Lysine in treatment of hyperornithinemia.
abstract: 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.
