BMD is prescribed by the balance of bone resorption and osteogenesis. In osteoporosis, this balance collapses according to a certain cause, bone loss starts as a result because bone resorption exceeds osteogenesis. Since a bone turnover marker shows the bone metabolism at the time of measurement quantitatively, it is thought that the change in BMD is reflected. Therefore, it is in predicting bone reduction of the future and fast bone loser identifying is expected by measuring bone turnover markers. Reduction of bone density is large in high turnover of bone metabolism, and it is shown clearly by recent research that the risk of fracture goes up. There is the necessity for evaluation of the bone turnover markers which made fracture the end point also in Japan.
骨密度由骨吸收和成骨作用的平衡所决定。在骨质疏松症中,这种平衡因某种原因而崩溃,由于骨吸收超过成骨作用,骨丢失由此开始。由于骨转换标志物能定量显示测量时的骨代谢情况,因此人们认为它能反映骨密度的变化。所以,通过测量骨转换标志物有望预测未来的骨质减少情况并识别快速骨质流失者。在骨代谢高转换时骨密度降低幅度较大,最近的研究清楚地表明骨折风险会上升。在日本,也有必要对以骨折为终点的骨转换标志物进行评估。
