Active clinical trials for "Osteoporosis"

This study will assess the incidence of osteoporosis and osteoporotic fracture risk of registered home health patients in the Anatolian side of Istanbul.

Osteoporosis pseudoglioma (OPPG) syndrome is a rare autosomal recessive condition of childhood osteoporosis and congenital blindness for which new treatments are needed. We have found that body fat is increased in OPPG and muscle mass is reduced. We hypothesize that growth hormone therapy will improve muscle mass and bone strength in OPPG.

Esophagectomy is most curative treatment to esophageal cancer. However, osteoporosis , which is characterized by both the loss of bone mass and the deterioration of bone architecture, is a serious complication in the long course after surgery. The aim of the present study was to evaluate osteoporosis by using high-resolution peripheral quantitative computed tomography (HR-pQCT) in the long course after esophagectomy. At least 3 years should have elapsed since operation without recurrence of esophageal cancer.

In osteoporosis, sarcopenia is a common condition. Sarcopenic measurements can be made by evaluating muscle thickness in different regions. We aim to evaluate lumbar muscle losses in patients with osteoporosis in the lumbar region and to examine whether these muscle losses are correlated with the level of osteoporosis. The patients will be divided into 3 groups as healthy, osteopenic and osteoporotic according to DEXA measurements. Demographic values, comorbidities, osteoporosis drugs used, fracture histories, L1-4, L2-4, femoral neck and total BMD and t values of the patients, psoas and multifidus muscle measurements will be made at L2-L3 level in Lumbar MR imaging. Lumbar MR muscle measurements will be made by 1 physician blind to the DEXA values of the patients.

Osteoporosis is an age related disease in which a person's bone slowly becomes weaker with time. The bones may become so weak that they break easily such as a fall from standing height. The most commonly broke bones in osteoporosis are those of the hip, the spine or the wrist. Osteoporosis runs in families meaning that genetic differences explain why some people break bones in old age and other do not. Genetic studies have been done that show the the genes associated with spine (vertebral) fractures (broken bones) and hip fractures are different, suggesting that osteoporosis of the spine is not the exact same disease as osteoporosis of the hip. Genetic studies tell us what part of the genome (i.e. genes) are associated with a disease, but do not tell us how these genes act biologically to cause that disease. In this study, we seek to determine how the genes uniquely associated with spine osteoporosis behave in normal and aged bone, to determine how they interact with each other as a team to impact spine bone. In this study, we will measure gene activity (so called gene expression) in bone samples taken from people undergoing major spine deformity surgery. We will using genetic data from these patients to determine how gene activity is controlled in bone and how that relates to measures of bone health such as bone mineral density data. The results of this study will provide critical data regarding how osteoporosis of the spine happens, and these data will be used to find better and safer treatments to prevent bone fractures of the spine that happen with age.

Multi-center,double blind randomized phase III placebo controlled study in 250 men with histologically proven prostate cancer with out bone metastases who are beginning ADT therapy and who will receive concomitant treatment with either oral Fosamax 70mg once weekly or placebo for one year.These men will be treated and follow up for one year,during which time changes in BMD, markers of bone resorption and formation will be monitored.All patients will receive calcium and vitamin D through out the study.

This is the second phase of a study designed to determine the immunological effects of long-term exercise on risk factors for ischemic heart disease (phase 1) and osteoporosis (phase 2). The results indicate that six months of moderate intensity exercise reduces bone resorption and increases the secretion of anti-osteoclastogenic cytokines by peripheral blood mononuclear cells.

The present study aims to develop a technique based on a single dose of a calcium isotope, which enables to determine the effect of a nutritional intervention on bone calcium metabolism. For this purpose nutritional interventions with calcium, vitamin D and vitamin K will be applied in postmenopausal women. Treatment effects will be determined by the urinary excretion of the calcium isotope and related to classical bone markers.

The objective of this study is to investigate the pharmacokinetics, safety, and tolerability of AK159 administered to healthy postmenopausal women.

There is growing evidence that patients undergoing bone mineral density testing (BMD) often do not take important steps to improve their bone health. The investigators will conduct a randomized-controlled trial to evaluate the impact of a novel and practical patient activation intervention (mailing patients their bone density test results) on the quality of bone-related healthcare and the cost-effectiveness of BMD testing. Equally important, the investigators intervention could easily be modified to include other patient populations and chronic diseases.
