Active clinical trials for "Osteoporosis"

The aim of this study is to determine the effect of aromatase inhibitors therapy on bone mineral density and compare it to the effects of tamoxifen and no hormonal therapy.

The aim of this study is to identify patients with problem list gaps and intervene to correct these gaps by creating clinical decision support interventions that alert providers to likely problem list gaps and offer clinicians the opportunity to correct them. The investigators will randomize the clinics that will receive the intervention and formally evaluate the study after a period of 6 months for improved problem list completeness to determine the effectiveness of our intervention.

The study aims to determine the efficacy and best methods for predicting hip fractures and diagnosing post-menopausal osteoporosis using three dimensional structural engineering models (SEMs) of proximal femoral bone produced using a Hologic Discovery duel-energy x-ray absorptiometry scanner and Hologic's new 3D Hip(TM) software in comparison to three dimensional SEMs produced using quantitative computed tomography - the current gold standard.

An increased skeletal fracture risk in diabetes has only recently been recognized. This human study is designed to elucidate the effect of Type 1 diabetes on bone remodeling and on structure.

Background: Osteoporosis is a high-prevalence disease with a strong genetic component. Nucleotides, including ATP (adenosine 5'-triphosphate) and its purinergic receptors, play a role in bone physiology. Single nucleotide polymorphisms (SNPs) in the P2X7 receptor gene were recently found to be associated with fracture risk in a cohort of postmenopausal women. Objective: To investigate associations between purinergic receptor SNPs and osteoporosis risk in humans. Genetic data from a fracture cohort in the Netherlands with high prevalence of osteoporosis will be analyzed. Furthermore, effects of aberrant purinergic receptor signalling on bone turnover markers will be assessed ex vivo. Design: The cohort will include app. 1,000 fracture patients of 50 years and older, who will be recruited at the Maastricht University Medical Center during standard medical follow-up after a clinical fracture. The standard medical follow-up includes assessment of bone mineral density (BMD) by Dual-Energy X-ray Absorptiometry (DXA), if necessary followed by medication for osteoporosis. Prior to medication, blood samples will be collected from fracture patients to be genotyped for purinergic receptor SNPs and analyzed for biochemical markers of bone turnover. Systemic correlates of osteoporosis will be compared between osteoporotic subjects (i.e. low BMD) and non-osteoporotic controls (i.e. normal to high BMD). Subsequently, whole blood assays in patient subgroups (n=20 per subgroup), based on BMD and purinergic receptor SNPs, will be performed to evaluate ex vivo effects of ATP and related nucleotides bone markers. Study population: Patients of 50 years and older attending an outpatient osteoporosis clinic at the Maastricht University Medical Center for standard medical follow-up after a clinical, non-pathological fracture. Primary outcome parameters: BMD and purinergic receptor SNPs. Secondary outcome parameters: Bone markers.

The purpose of this study is to determine whether bone mineral density has increased in a subgroup of postmenopausal osteoporotic women from study CR9108963, between 6 and 12 months following cessation of ronacaleret therapy.

Both conditions hypogonadism and immobilisation (paraplegia) may contribute or lead to decreased bone mineral density resp osteoporosis. In this study bone mineral density is assessed in hypogonadal paraplegic patients, who are on standard prophylactic therapy for osteoporosis and and on a standard physiotherapy exercise program one group receiving Nebido for testosterone replacement (TRT). The additional effect of TRT on bone mineral density / osteoporosis is assessed (CT scan lumbar spine).

This study is a regulatory post-marketing surveillance in Japan, and it is a local prospective and observational study of patients who have received Julina for postmenopausal osteoporosis. The objective of this study is to assess safety and efficacy of using Julina in clinical practice. A total 100 patients will be recruited and followed 3 years since starting Julina administration.

Study is being done to determine if it is possible to use saliva to measure bone specific proteins and predict bone turnover which could be used in the treatment of osteoporosis.

The purpose of this study is to assess the impact of disease management interventions on bone mineral density (BMD) screening rates and osteoporosis treatment rates in women age 65 years or older.
