Urinary beta-1-galactosyl-0-hydroxylysine (GH) as a marker of collagen turnover of bone
Abstract
beta-1-galactosyl-0-hydroxylysine (GH) was measured in the urine of 59 women and 48 men, aged 30-79 years, by High Performance Liquid Chromatography (HPLC) of the dansylated derivative. Vertebral mineral density, measured by quantitative computed tomography (QCT), and urinary GH were inversely correlated (r = -0.74; P less than 0.001). High rate of bone mineral loss is associated with a high urinary GH excretion. Measurement of GH in urine provides a simple and noninvasive method for the evaluation of the extent of bone resorption in large groups of subjects and appears to be more specific than urinary hydroxyproline excretion.
