Abstract
OBJECTIVES
Recombinant teriparatide, a bone anabolic agent, is known to result in a net positive bone balance and reduce vertebral and nonvertebral fracture incidence. The objective of this study was to evaluate the changes of bone mineral density (BMD) and bone turnover markers after one-year teriparatide treatment in Korean postmenopausal women with osteoporosis.
METHODS
The enrolled postmenopausal women with osteoporosis were administered teriparatide 20microg/day injection for one year. BMD at the lumber spine and the hip were measured at baseline and after one year by dual-energy X-ray absorptiometry. Also, serum bone turnover markers, such as osteocalcin, C-telopeptide of collagen cross-links (CTX), and alkaline phosphatase were measured at baseline and after one year.
RESULTS
Lumbar spine BMD increased from baseline (4.4%, P<0.01), but femoral neck BMD decreased from baseline (-9.7%, P<0.05). Bone turnover markers, such as osteocalcin (148.5%), CTX (67.6%), and alkaline phosphatase (56.7%) increased from baseline (P<0.001 for all).
CONCLUSION
One year of teriparatide treatment significantly increased lumbar spine BMD and bone turnover markers in Korean postmenopausal women with osteoporosis. The large-populated prospective study with longer administered period will be needed in the future.
