Abstract

Serum levels of hydroxylysyl pyridinoline and lysyl pyridinoline were quantified in uremic patients undergoing maintenance hemodialysis and in healthy subjects. Pre-hemodialysis serum levels of hydroxylysyl pyridinoline and lysyl pyridinoline in the hemodialyzed patients were significantly higher than those in healthy subjects. Serum levels of hydroxylysyl pyridinoline and lysyl pyridinoline decreased significantly after hemodialysis with reduction rates of about 40%. Pre-hemodialysis serum levels of hydroxylysyl pyridinoline and lysyl pyridinoline correlated significantly with intact parathyroid hormone, osteocalcin and bone-specific alkaline phosphatase. Lysyl pyridinoline showed better correlations with these parameters than hydroxylysyl pyridinoline. Parathyroidectomy markedly decreased serum levels of hydroxylysyl pyridinoline and lysyl pyridinoline. These results indicate that serum pyridinolines, especially lysyl pyridinoline, may be used as specific biochemical markers of bone resorption in hemodialyzed patients. © 1995.
