title: Urinary excretion of hydroxyproline, hydroxylysine and hydroxylysine glycosides by patients with Paget's disease of bone and carcinoma with metastases in bone.
abstract: Patient's with carcinoma metastases in bone and Pagent's disease of bone have different patterns of collagen metabolite excretion. Both forms of bone disease resulted in an increased excretion of total hydroxyproline and the ratio of glucosylgalactosylhydroxylsine to galactosylhydroxylysine was below normal. The excretion of glucosylgalactosylhydroxylysine and galactosylhydroxylysine was increased in all patients with carcinoma metastases in bone while the excretion of glucosylgalactosylhydroxylysine in patients with Paget's disease. The ratio of total hydroxylysine (free hydroxylysine + glycosylated hydroxylysines) to total hydroxyproline was normal in patients with carcinoma metastases in bone and below normal in patients with Paget's disease bosne. The pattern of urinary collagen metabolite excretion is a more specific indicator of the presence of bone disease than is the measurement of the excretion rate of any individual collagen metabolite. Bone diseases of different etiologies may result in different patterns of urinary collagen metabolite excretion.
