Filter by:The purpose of this study is to determine whether women with major depression lose bone mass at a faster rate than women without depression. This study will also determine if the drug alendronate can maintain or increase bone mass in premenopausal women with major depression and osteoporosis. Depression may be a major risk factor for osteoporosis; it is associated with abnormally elevated stress hormone levels that may contribute to bone loss. This study will evaluate bone mass in women with depression and healthy volunteers. Participants will undergo psychiatric, medical, dietary, and stress hormone evaluations and bone mineral density (BMD) measurements. Participants with depression will be divided into two groups: those with normal BMD and those with low BMD. Depressed participants with normal BMD will be compared to a control group of healthy premenopausal women with normal BMD and followed for 36 months. Dual energy X-ray absorptiometry (DEXA) determinations will be made at months 6, 12, 24 and 36; bone turnover and endocrine parameters of depression will be measured every 3 to 6 months. Participants with depression and low BMD will be randomly assigned to receive either alendronate or placebo (an inactive pill) once a week for 24 months. Participants will receive calcium and vitamin D supplements daily. DEXA determinations will be performed at screening, and at Months 6, 12, 18 and 24; bone turnover and endocrine parameters of depression will be measured every 3 to 6 months. For both groups, up to four of the visits may optimally be done as inpatient stays of two nights. All remaining visits are as outpatients.
OBJECTIVES: I. Determine the frequency and severity of osteopenia and osteoporosis in patients with thalassemia major who undergo dual energy x-ray absorptiometry, and correlate these findings with other relevant endocrinologic measurements.
OBJECTIVES: I. Determine the efficacy of alendronate sodium in treating osteopenia (generalized bone density and focal bone lesions) in patients with Gaucher's disease.
Osteoporosis, a condition in which bones are fragile and break easily, is a major health problem for postmenopausal women. Research studies have shown that both estrogen/progestin replacement therapy (hormone replacement therapy, or HRT) and alendronate are effective in preventing and treating osteoporosis. However, because these drugs work in somewhat different ways, a combination of the two drugs might protect women from osteoporosis better than either drug alone. In this study we will test whether HRT and alendronate given together for 3.5 years to postmenopausal women with low bone mass will have a greater effect on bone than either HRT or alendronate given alone. We will also give every participant in this study calcium and vitamin D supplements.
