A Comparison of the effect of Synthetic Hormone Replacement therapy on Bone Mineral Density and Biochemical markers of Bone metabolism / 대한산부인과학회잡지

ABSTRACT

OBJECTIVE: To determine the effect of hormone replacement therapy on bone mineral density and biochemical marker of bone metabolism in postmenopausal women receiving hormone replacement therapy. METHOD: We have treated two groups of menopausal women for 4 years; Group 1 received Conjugated Equine Estrogen 0.625 mg (Premarin(R)); Group 2 received Cyclic combined therapy, estrogen and progestin, (Premarin(R) 0.625 mg per day, Provera(R) 10mg per day for 12days), Group 1 was hysterectomized women, received Conjugated Equine Estrogen 0.625 mg per day. We compared the change of bone marker, osteocalcin and bone mineral density during therapy. RESULT: The data demonstrated a beneficial effect in bone marker, osteocalcin decreased in two groups from the baseline values. And hormone replacement therapy shows the beneficial effect in bone mineral densities. Spine BMD increased in two groups by 3.67%, 3.04% after 4years. Femur BMD increased in two groups by 5.34%, 5.25% from the initial value after 4 years. CONCLUSION: Our study results suggest that single estrogen therapy and cyclic combined therapy have benificial effect on increased BMD and decreased bone marker, osteocalcin. Their effects were not signigicantly different between two groups.
