Baseline cathepsin K correlated positively with crosslinked telopeptide of type I collagen (sCTX) and urinary calcium, but not with total or bone-specific alkaline phosphatase (ALP).
These markers include the formation markers of type I collagen turnover, serum N-terminal (PINP) and C-terminal (PICP) propeptides of type I procollagen, and serum N-terminal propeptide of type III procollagen (PIIINP), as well as the resorption markers serum cross-linked C-terminal telopeptide of type I collagen (ICTP) and urine cross-linked N-telopeptides of type I collagen (Ntx) and deoxypyridinoline (DPD) (1-5).
Thus far, urinary pyridinoline and deoxypyridinoline, serum osteocalcin, bone specific alkaline phosphatase, serum type I collagen cross-linked N-telopeptides (NTx), the C-terminal pyridinoline cross-linked telopeptide of type I collagen, and urinary excretion of NTx were reported to undergo circadian periodicities with high values at night (1-5).
They also showed that the resorption marker concentration (C-terminal telopeptide of type I collagen and deoxypyridinoline), but not the formation marker (bone alkaline phosphatase), is correlated with severity of bone pain and suggest that the resorption markers might be of use to assess the extent of bone pain in cancer patients.
