Filter by:The purpose of this study is to develop new treatment options for osteoporosis in men. The Investigators will study two medications and three treatment regimens. First, risedronate (FDA approved) will be studied as monotherapy. Second, the investigators will study injectable parathyroid hormone (PTH 134, teriparatide; FDA approved), as a therapy for male osteoporosis. PTH, a naturally occurring hormone produced by the parathyroid glands, is one of the most important regulators of bone metabolism. The drug being studied in this protocol, teriparatide, is the first aminoterminal 34 amino acids of the native 84amino acid peptide. Teriparatide contains all of the classical biological activities of native PTH. In studies of postmenopausal women, in a small study of 23 men with osteoporosis and a larger study of 437 men treatment with teriparatide led to significant increases in bone density. Although teriparatide and actonel are now approved for osteoporosis in men additional studies of these medications are needed in order to establish how best to use these drugs. This study is focused on an entirely new treatment approach, namely the combination of two medications for the treatment of osteoporosis risedronate with teriparatide to evaluate whether combination therapy is superior to therapy with either medication alone. This study is also designed to assess the extent to which risedronate maintains increases in bone density after a course of mono or combination therapy.
Osteoporosis and falls occur with increasing frequency among the elderly. Osteoporosis and fall increases the risk of fracture. Falls in the elderly are associated with a high morbidity and mortality with potentially life-threatening consequences of falls including fractures. Besides fracture fall may cause long term problems such as disability fear of falling and loss of independence. Today osteoporosis is diagnosed by bone scan of the hip and spine. The investigators want to investigate whether other more accessible and less expensive testing methods can be used to diagnose osteoporosis. Additionally, the investigators will examine the incidence of osteoporosis among the elderly in the municipality of Odense. Finally, the investigators would like to investigate the association between factors that can lead to falls and to investigate the performance of older and whether there are changes in functional ability over time.
In a group of HIV-positive patients under observation since their first exposure to ART or monitored off of ART, BMD changes over one year will be determined. For each subject, the investigators will also determine associations between changes in BMD and 1) ART initiation, 2) cumulative viremia (measured by copy-years viremia), and 3) inflammation (evaluated through the measurement of interleukin-6 {IL-6}, tumor necrosis factor alpha {TNF-a}, high-sensitivity c-reactive protein {hsCRP}). Hypotheses: BMD will decrease less in persons initiated on ART than those monitored off of ART, after excluding those subjects treated with tenofovir. BMD will decrease most significantly in HIV-positive subjects with the highest levels of cumulative viremia. HIV-positive persons with highest cumulative viremia will have the highest levels of inflammation, as measured by pro-inflammatory cytokines. Additionally, the investigators will evaluate fracture incidence in a 5% National Medicare sample and fracture association with the use of varying ART medications among dual-eligible persons in Medicare and Medicaid datasets. Hypotheses: Fracture incidence will be greater in HIV-positive subjects compared to HIV-negative subjects.Fracture incidence will be greatest in subjects with the shortest duration of ART exposure.
The purpose of this study is to estimate the percent change from baseline in lumbar spine bone mineral density (BMD) following multiple-dose administrations of romosozumab in postmenopausal women with low BMD previously treated with alendronate.
A multicenter, randomized, double-blind, active-controlled, phase III clinical trial to evaluate the efficacy and safety of Dp-R206 and Bonviva for 16 weeks once a month on the improvement of vitamin D in postmenopausal women with osteoporosis.
The purpose of this study is to determine if treatment with romosozumab is effective in preventing fractures in women with postmenopausal osteoporosis
The study seeks to determine the impact of assessing risk for osteoporosis in women on patient and physician behaviors through a pharmacist directed osteoporosis screening program. Women will be offered a heel ultrasound to screen for their bone density and may or may not be asked questions about their risk for bone fracture. Pharmacists will counsel and educate all women on ways to prevent the onset of osteoporosis. Women will be telephoned three months after the screening and asked a series of 10 questions to follow up on decisions made by their physicians or changes made to their health behaviors related to bone health.
The primary aim of the study is the comparative effect of zolendronic acid versus denosumab on serum sclerostin levels in postmenopausal women with low bone mass. Secondary aims are their comparative effect on serum dickkopf-1, osteoprotegerin, receptor activator of nuclear factor kappaB ligand (RANKL) and bone turnover markers (procollagen type I N-terminal peptide [PINP] and C-terminal cross-linking telopeptide of type I collagen [CTX]).
The purpose of the study is to determine the effect of forearm exercise on forearm bone density in post-menopausal women with or without primary hyperparathyroidism. The investigators hypothesize that forearm exercise will increase forearm bone density in patients with primary hyperparathyroidism more so than in patients without primary hyperparathyroidism.
The 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.
