Atorvastatin (Lipitor) to Prevent Bone Pain
OsteoporosisIn the proposed randomized double blind cross-over placebo controlled study, the researchers intend to investigate if Atorvastatin (FDA approved statin for children) can be used to alleviate the symptom of bone pain (acute phase reaction) that is commonly associated with initial doses of pamidronate or zoledronic acid, and also the mechanism that underlies this proposed beneficial effect of Atorvastatin. The primary outcome studied will be alleviation of bone pain by Atorvastatin compared to placebo by visual analogue pain scale in children treated with pamidronate or zoledronic acid. The secondary outcome investigated will be changes in blood count and γδT cell count, C-reactive protein (CRP) and cytokine levels of interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-α) and gamma interferon (γ-IFN) following treatment with Atorvastatin compared to placebo.
Isoflavones for Promoting Calcium Absorption and Preventing Bone Loss in Post Menopausal Women
OsteoporosisOsteopeniaEstrogen is a hormone that helps prevent calcium loss and bone breakdown. During menopause, estrogen levels decrease. Insufficient amounts of estrogen may lead to bone loss and possibly osteoporosis. Isoflavones are natural compounds found in soy plants that may help provide protection against bone loss. This study will evaluate the effect of soy isoflavones on calcium absorption and bone loss in post menopausal women.
Danish Osteoporosis Prevention Study
OsteoporosisHypothesis: Use of hormone replacement therapy (HRT) decreases the incidence of fractures in early postmenopausal women. The project was initiated in 1990, and the inclusion ended in 1993. A total of 2,016 early postmenopausal women were divided into two groups: The first group accepted randomisation to HRT or not, and the second group was allowed to choose HRT or not. The study was not blinded. Main measurements were fracture risk over 20 years, changes in bone mineral density over 20 years, and side effects, mainly breast cancer.
Comparison of Raloxifene and Lasofoxifene - A Randomized, Blinded Study of These Drugs and Placebo...
OsteoporosisTo compare the effects of 2 years of lasofoxifene treatment with 2 years of raloxifene 60 mg/day use and 2 years of placebo use on bone mineral density (BMD) of the lumbar spine.
Exercise and Flax-Based Nutritional Supplementation for Lowering Cholesterol
Metabolic SyndromeOsteoporosisThe purpose of our study is to use a flaxseed-based nutritional supplement in combination with exercise training (walking) for improving cholesterol levels. We hypothesize that exercise training will improve cholesterol profile and that adding supplementation with a flaxseed nutritional supplement will further improve cholesterol profile.
Postmenopausal Estrogen/Progestin Interventions (PEPI)
Bone DiseasesCardiovascular Diseases9 moreTo assess the effects of various postmenopausal estrogen replacement therapies on selected cardiovascular risk factors, including high density lipoprotein cholesterol, systolic blood pressure, fibrinogen, and insulin and on osteoporosis risk factors. Conducted in collaboration with the National Institute of Child Health and Human Development, the National Institute of Arthritis and Musculoskeletal and Skin Diseases, The National Institute of Diabetes and Digestive and Kidney Diseases, and the National Institute on Aging. The extended follow-up is for 3 years focusing on endometrium and breast evaluation.
Calcium and Bone Mass in Young Females
OsteoporosisWe originally suggested that calcium in the diet is important in determining the amount of bone (bone mass) that builds up in young adults. We are testing the effect of calcium on bone mass in 354 Caucasian (white) girls. At the start of this 7-year study, the average age of the girls was 11 years, and they had not yet reached puberty. The study will also provide information about the effect of calcium on body composition (body fat) and blood pressure in young women. We have been giving calcium to one group of participants in this study and giving a placebo (an inactive pill, or "sugar pill") to the other group. The results of this research will be important in preventing osteoporosis, because building more bone as a young person should reduce a woman's chances of developing osteoporosis later in life.
Denosumab for Prevention of Post-Teriparatide Bone Loss in Premenopausal Women With IOP
Adult Idiopathic Generalized OsteoporosisThe purpose of this research study is to evaluate antiresorptive therapy with denosumab (Prolia) for prevention of bone loss after stopping teriparatide (TPTD) in premenopausal women with idiopathic osteoporosis. Premenopausal women who have received TPTD in the FDA Orphan Diseases Program-funded trial, "A Phase 2 Study of Teriparatide for the Treatment of Idiopathic Osteoporosis in Premenopausal Women" (NCT01440803) may be eligible to participate in the current study, a 36-month open-label pilot study of denosumab (Prolia®, 60mg subcutaneous (SC) every 6 months). The goals of the study are to estimate the effects of denosumab on central and peripheral, as well as trabecular and cortical, bone mass and microstructure and to obtain preliminary data to inform the design of a future randomized study. This study presents the first opportunity to study the effects of denosumab after TPTD in this unique and severely affected group of young women.

Teriparatide for Fracture Repair in Humans
OsteoporosisAge-Related1 moreThis study will test the hypothesis that daily subcuaneous administration of 20µg of teriparatide (TPTD) as compared to daily subcuaneous placebo for twelve weeks accelerates proximal 2-segment humerus fracture healing and improves the three dimensional structural properties of bone as measured via quantitative bone image analysis and finite element modeling assessed by quantitative computed tomography.
Soluble Corn Fiber and Calcium Utilization in Adolescents
OsteoporosisThe purpose of this study was to determine the effect of soluble corn fiber on calcium absorption and retention and gut microflora in adolescent boys and girls.
