Modifications in urinary hydroxyproline concentrations were studied in various collagen degradation diseases. A significant increase in hydroxyprolinuria was found in both men and women with Paget's disease in all age groups considered. Significant increases were found in men with the same pathologies. Rheumatoid arthritis also increased urinary hydroxyproline in both males and females. It therefore seems that bone tissue pathologies are reflected in the metabolism of hydroxyproline as are articular connective tissue pathology strictly related to it.
