Active clinical trials for "Osteoporosis"

The primary objective of this study is to compare efficacy and safety of two formulations of teriparatide 20 mcg/day plus calcium and vitamin D in postmenopausal women with osteoporosis.

The aim of the project is to execute a double-blind, parallel, randomized 12-month intervention trial on postmenopausal women with osteopenia (low bone mineral density), in order to determine the effects of daily intake of fermented red clover (RC) extract on estrogen dependent bone mineral resorption when compared to placebo. Both groups will recieve equivalent daily calcium, vitamin D and magnesium supplements. The project will also assess whether bioactive compounds in RC can reduce the risk of developing cardiovascular disease.

Balance control, physical activity and health related quality of life will be assessed before and after a 10 to 12 weeks training program as well as 6 and 12 months thereafter in 200 elderly (>60) with balance problems (100 with osteoporosis, 100 with Parkinson's disease). Osteoporosis subjects will be assigned to 3 groups (balance training, balance training and Nordic walking, or control group) and Parkinson's subjects to 2 groups (balance training or a control group). The training will be progressive and specific incorporating dual task exercises (directly related to an increased risk of falling). Clinical and laboratory gait and balance measures as well as questionnaires will be used to assess physical function and quality of life. An earlier study, investigating this training program in healthy elderly with balance problems showed that the training was well-tolerated and effective, with a significant increase in balance control, physical function and activity. In this study, we expect that an improvement in balance function, physical activity and health related quality of life, which will lead to a decreased number of falls, prevent and/or postpone incidence of a hazardous fall and thereby reduce the burden on the health care system. Our model for functional balance training and outcome methods will expand techniques and tools available to physical therapists and health care scientist treating and evaluating patients with loss of balance function. Elderly receiving therapy with the goal to improve or recuperate physical function and balance will benefit from this project.

This study is being conducted to evaluate the effect treatment has on serum P1NP levels, a biomarker of bone formation in postmenopausal women with low bone mass.

RATIONALE: The increasingly prolonged and extended use of androgen deprivation therapy (ADT) in the treatment of prostate cancer, usually achieved through the administration of LHRH agonists, has raised concerns about long-term toxicities, in particular osteoporosis and adverse metabolic changes which may be associated with type II diabetes and increased cardiovascular risk. An alternative approach is to investigate other methods of ADT. Oral oestrogen has been shown to be as effective as LHRH and surgical orchidectomy in achieving castrate levels of testosterone and has equivalent or improved prostate cancer outcomes but is not used routinely as first-line therapy because of the risk of cardiovascular system (CVS) complications. The CVS complications have been attributed to first-pass hepatic metabolism. Administering oestrogen parenterally avoids the entero-hepatic circulation and so is expected to mitigate the risk of CVS toxicity whilst still effectively suppressing testosterone to castrate levels. This hypothesis has been supported by results from the early stages of this trial which have provided sufficient indication of the safety and efficacy of the patches to warrant further investigation of the treatment in this setting, as recommended by the IDMC.. PURPOSE: This randomized phase III trial is studying how well the estrogen skin patch works compared with luteinizing hormone-releasing hormone agonist injections in treating patients with locally advanced or metastatic prostate cancer.

After a complete spinal cord injury (SCI), the patient becomes wheelchair-dependent, and the associated lack of weight-bearing and inactivity of paralysed muscles can lead to extensive bone loss in the long bones of the legs. It has been documented that the most rapid phase of bone loss is during the first year, but bone loss can continue for a number of years post-injury, leading to an increased risk of fracture in chronic SCI. Through a previous longitudinal study, in which we described rates of bone loss in the first year of SCI using peripheral Quantitative Computed Tomography (pQCT), we showed that there is a subset of patients who suffer from extremely rapid bone loss, losing up to 50% of their bone mineral density (BMD) in the first 12 months post-SCI. As a result of this work, we now know that, by performing repeat bone scans within months of injury, we are able to detect and "red-flag" those patients at highest risk of rapidly weakening bones. We propose that, once these patients have been identified, there is an opportunity to intervene with bone-stimulating interventions within months of injury, before BMD reaches dangerously low values. In this new phase of the research, therefore, we are introducing an intervention phase to the longitudinal pQCT study. For this, we aim to trial a physical intervention, Whole Body Vibration (WBV), that could potentially reduce rates of further bone loss in fast bone losers. Vibration would achieve this by acting as a mechanical stimulus for bone cells, to encourage bone formation. If shown to be successful as an early bone-stimulating intervention, it may prove to be a tool for reducing future fracture risk in patients with SCI.

This proposed study was designed to investigate the prevalence of a 5-year incident osteoporotic fracture and evaluate the association of a 5-year change of 25-hydroxyvitamin D (25[OH]D)/bone turnover makers/bone mineral density (BMD) with the incident fracture in the Chinese postmenopausal women, based on an endeavor of a 5-year post-baseline follow-up visit of a previous cross-sectional study, PK-VF, in which 1724 participants were enrolled and examined.

This is a randomized, controlled pilot study to evaluate the feasibility and acceptability of a single 2-hour culinary medicine intervention for bone health among individuals with age-associated low bone mass.

The purpose of this study is to estimate Osteoporosis' prevalence in France and is a pilot study in the Department of the Alpes-Maritimes.

Hypothesis: one-dose pamidronate will prevent post-operative bone loss in children at risk for low bone density Plan: children with chronic disease such as CP, spina bifida, etc. will be recruited pre operatively and studied with DXA scan. After surgery, children will be randomized to receive either pamidronate or saline. Repeat DXA scan will determine bone lost after end of immobilization or nonweightbearing.
