Deoxypyridinoline
Deoxypyridinoline (DPD) is a breakdown product of type I fibrillar collagen, it occurs mainly in Type I collagen of bone. DPD shows a high specificity for bone, and the measurement of urinary DPD is not influenced by newly collagens and dietary intake. DPD cross-links of type 1 collagen are excreted in urine either as free or peptide-bound moieties. It is the peptide-bound cross-links that decrease by the greatest amount in response to bisphosphonate therapy. DPD is one of the most extensively characterized biochemical bone markers, but the interpretation of results is hampered by biologic and other preanalytical variability. Biochemical bone markers can provide a valuable tool in the management of metabolic bone diseases. Their most recognized application in clinical practice is for monitoring treatment for osteoporosis as an adjunct to bone mineral density measurements. Other applications that have been investigated include their use as a diagnostic tool for bone diseases other than osteoporosis and as predictive markers for bone loss and the risk of bone fracture. DPD measured in urine follow a circadian or diurnal cycle with a peak in the early morning and nadir in the late afternoon to early evening. The magnitude of the diurnal change, i.e., nadir concentration divided by peak concentration, expressed as a percentage is around 70\\% (range, 53-75\\%). (PMID: 11805003, 17229003, 16751696). Derived from collagen cross-links formed between adjacent lysine residues in type I collagen of bone and dentine. Released into serum during bone resorption
