[Chromatographic analysis of urinary amino acids in Paget's disease. II : clinical study]. / Analyse chromatographique des acides aminés urinaires au cours de la maladie de Paget Partie II : étude clinique

ABSTRACT

The authors demonstrated in the urine of certain patients a peptide form of hydroxyproline and of glutamic acid. This peptide was found in patients with Paget's disease who presented clinical and laboratory signs of an evolutive episode and in other patients who presented restructuration of bone of a radiologicaly type. This peptide was one of the factors determining the increase in the total hydroxyprolinuria. The demonstration of the peptide provokes discussion as to its origin, and also of the possibility of using it as a biochemical parameter.
