[Clinical usefulness of bone turnover markers with the treatment of osteoporosis].

Bone turnover markers (BTMs) are known the bone formation marker, the bone resorption marker and the bone matrix related marker participating in bone quality, respectively. In the Guidelines for the Use of Bone Metabolic Markers in the Diagnosis and Treatment of Osteoporosis (2012 Edition) from publishing Japan Osteoporosis Society Committee, the newly and commonly BTMs were considered to give the normal reference value in Japanese people, the reevaluation of MSC, and the influence of renal function on BTMs, respectively. The flow chart of the measurement of bone resorption markers and bone formation markers when selecting drug treatment for osteoporosis, the measurement of ucOC and bone resorption markers when selecting drug treatment in osteoporosis, and the evaluation of therapeutic effects of bone antiresorption drugs using bone resorption markers were corrected newly in the guideline 2012 edition. It is thought that the BTMs have been continued more developing as essential biomarker with the treatment of osteoporosis in the future.
