[Biochemical markers of bone remodeling: recent data of their applications in managing postmenopausal osteoporosis].
The recent development of new biochemical markers has considerably improved the non invasive exploration of bone turnover. Currently, the most sensitive markers to access bone formation are osteocalcin, bone alkaline phosphatase and N-terminal propeptide of type I procollagen. Blood or urinary immunoassays of pyridinoline, deoxy-pyridinoline and terminal telopeptides type I of collagen are currently the best indices to evaluate the bone resorption. The principal application fields of biochemical markers in postmenopausal osteoporosis, in combination with the measurement of the bone mineral mass, are primarily the monitoring of anti-resorptive therapy response and prediction of bone loss and risk of fractures. In fact, treatment with anti-resorptive drugs is followed by rapid decrease of bone markers levels (3 months for the markers of resorption and 6 months for those of osteo-formation ), whereas the bone mineral density measurements requires at least two years to change significantly.
