Filter by:Tibolone, a tissue-selective compound with a combination of estrogenic, progestogenic and androgenic properties, is used as an alternative for estrogen or estrogen plus progesterone hormone therapy for the treatment of symptoms associated with menopause and osteoporosis. The current study compares endometrial histology, biochemistry (hormone levels) and gene-expression profiles after short-term (21-days) treatment with tibolone, to the findings after treatment with estradiol-only (E2) and E2+Medroxyprogesterone Acetate (MPA) in healthy postmenopausal women undergoing hysterectomy for endometrial prolaps. Since short-term tibolone use results in increased spotting and bleeding but long-term treatment with tibolone has been shown to lead to an atrophic endometrium our hypothesis is that tibolone first displays a more estrogenic mode of action, which over time, is counterbalanced by tibolone's progestagenic properties
This study is structured to estimate the effect of denosumab, compared to placebo and alendronate, on several bone parameters.
Decreased bone strength is a serious medical problem present in many women with Anorexia Nervosa, or disordered eating. Women with weaker bones are more likely to suffer broken bones than women with normal bone strength. We are investigating whether a hormone that is naturally produced by the human body, called growth hormone, can help strengthen the bones of women with this type of disordered eating.
Osteoporosis, a disease in which the bones become weak and are more likely to break, is a major health problem in the United States. Too much acid in the body appears to be linked to loss of calcium via urine, bone loss, and muscle breakdown. The purpose of this study is to determine the effect of various doses of potassium citrate, a supplement that can neutralize acid, on bone density and muscle mass in older, healthy adults.
Osteoporotic fractures of the hip are a major cause of admission to long-term care facilities. Such fractures put patients at high risk for further fractures, pain and disability. Current data show that many patients in long-term care facilities do not receive FDA medications for their osteoporosis. This trial will test whether a multi-model intervention (which provides feedback about provider use of osteoporosis medications, information about osteoporosis, and currently approved osteoporosis medications)directed at physicians, other health care providers, and nurses will improve the number of prescriptions written for FDA approved medications for osteoporosis treatment.
This trial will test the hypothesis that among 20 children and adolescents from Children's Hospital, Boston with Crohn's disease, ulcerative colitis, systemic-onset juvenile rheumatoid arthritis, juvenile dermatomyositis, systemic lupus erythematosus, mixed connective tissue disease and vasculitis, treatment of glucocorticoid-associated osteopenia and osteoporosis with 18 months of alendronate (FOSAMAX®, Merck & Co., Inc.) will result in greater improvement in the mean change of individual AP spine bone mineral density (BMD) (gm/cm2) determined by dual energy X-ray absorptiometry (DXA) than treatment with 18 months of standard of care therapy.
The purpose of this study is to determine whether giving women feedback concerning their bone mineral density, combined with either an information leaflet or group education concerning osteoporosis changes women's behavior and/or bone density.
Efficacy: To investigate changes of structural bone properties in vivo using 3DpQCT ("Xtreme" CT, Scanco) in monthly oral ibandronate therapy for women with postmenopausal osteoporosis. Major structural bone parameters which determine bone strength and predict fracture risk earlier and more precisely are measurable in vivo by 3DpQCT. Safety: To assess the tolerability and safety of ibandronate therapy
The primary objective of this study is to assess the impact of physician's reinforcement using bone marker data on the subject's compliance (at least 50% drug taken) and persistence on treatment after one year in postmenopausal osteoporotic women.
Alendronate is a safe and effective drug for treating osteoporosis in post-menopausal women. However, its safety and efficacy in increasing bone mineral density in chronic peritoneal dialysis (PD) patients have not been investigated. Etidronate, another bisphosphonate, can suppress the extent of coronary artery calcification in chronic hemodialysis patients. The hypothesis of this study is that alendronate can increase bone mineral density and suppress aortic and coronary artery calcification in chronic peritoneal dialysis patients.
