Objective
To investigate the changes of BMD (bone mineral density), biochemical bone markers and lipid profiles after combination therapy of low dose estrogen (0.3 mg) and intermittent fluoride (monofluorophosphate) in postmenopausal osteopenia. Method: We studied 61 women with postmenopausal osteopenia from March 2002 to May 2005. Group I (n=30) was treated with low dose estrogen (0.3 mg), fluocalcic^Ⱂ (monofluorophosphate 100 mg+calcium 500 mg), and calcium (500 mg). Group II (n=31) was treated with standard dose estrogen (0.625 mg) and calcium (1,000 mg). BMD at the lumbar spine and femur, osteocalcin, deoxypyridinoline, and lipid profiles were measured at baseline and 2-year after treatment. Results: 1) Average postmenopausal periods were 2.8 years and 3.1 years in Group I and II, respectively. 2) BMD increased significantly in two groups, and BMD in group I increased significantly more than that in group II. 3) Deoxypyridinoline decreased significantly in two groups, and there was no significant difference between the two groups. 4) Total cholesterol and LDL cholesterol decreased significantly in two groups. Conclusion: Combination therapy with monofluorophosphate and low dose estrogen in postmenopausal osteopenia was more effective than standard dose estrogen therapy to prevent postmenopausal osteoporosis.

Objective
To compare the difference of bone mineral density (BMD), biochemical markers, and lipid profiles according to dosage of estrogen on combined therapy with estrogen and alendronate in postmenopausal osteoporosis. Method: We studied 81 women with postmenopausal osteoporosis (T-score＜2.5) from March 2002 to February 2005. Subjects were divided in two groups; Group I (n=36), treated with low dose hormone therapy (HT) (0.3 mg estrogen/1.25 mg MPA (Medroxyprogesterone acetate)) and alendronate, and Group II (n=45), treated with standard dose HT (0.625 mg estrogen/2.5 mg MPA) and alendronate. BMD at the L-spine and femur, osteocalcin, deoxypyridinoline, and lipid profiles were measured at baseline and 1 year after treatment.Results: BMD at the L-spine increased significantly in two groups and BMD at the femur increased but showed no statistical differences. Deoxypyridinoline and osteocalcin decreased significantly in two group. Total cholesterol and LDL (low density lipoprotein) cholesterol decreased significantly in two groups, no significant difference was observed between two groups in BMD, osteocalcin, deoxypyridinoline, and lipid profiles. Conclusion: We concluded that combined therapy with low dose estrogen and alendronate in postmenopausal osteoporosis showed similar therapeutic effect provied by combined therapy of standard dose estrogen and alendronate.
