Active clinical trials for "Osteoporosis"

Aim of this study is to evaluate in a population of old osteoporotic chronic kidney disease females the effect of denosumab: on bone mineral density (femoral T-score) at 24 months on bone mineral density evolution (femoral T-score) after 24 months of follow-up on bone mineral density evolution (lumbar T-score) after 24 months of follow-up on coronary and abdominal aorta calcification scores evolution after 24 months of follow-up on parameters of bone remodelling (OPG, RANKL, sclerostin, DKK-1), of mineral and calcium metabolism (FGF23 Ct, Klotho, PTH, 25(OH) vitamin D3, phosphorus, calcium, bone alklaline phosphatase, osteocalcin, CTX), of inflammation (CRP) after 24 months of follow-up on cardiovascular morbidity (cardiovascular events) and mortality after 24 months of follow-up the tolerance after 24 months of follow-up

The primary objective of the study was to characterize the effects of a single dose of denosumab on the pharmacokinetics (PK) of etanercept in postmenopausal women with low bone mineral density (BMD) and rheumatoid arthritis based on area under the serum concentration-time curve (AUC) and maximum observed serum concentration (Cmax).

This is a research study to determine the effects of functional electrical stimulation (FES) rowing and a drug called zoledronic acid in bone health. The investigators hoped to learn if zoledronic acid treatment will increase bone mineral density in persons with chronic spinal cord injury (SCI) who received it. The investigators also want to find out if zoledronic acid is safe for persons with SCI to take without causing too many side effects.

The purpose of the event-driven base study is to determine the safety and efficacy, especially fracture risk reduction, of odanacatib in postmenopausal women diagnosed with osteoporosis. In a placebo-controlled extension of the base study, participants continued to receive the same blinded study medication for a total of up to 5 years of blinded study medication combined between the base study and the extension. After participants received 5 years of blinded study medication, they received open-label odanacatib through the end of the first extension. Participants were then invited to enroll in a second extension study in which they received open-label odanacatib for an additional 5 years. Two imaging substudies (PN032-Base/Extension and PN035) were conducted for participants in the MK-0822-018 Study. Additional safety information was collected for participants who discontinued from the base study or the blinded first extension in an observational follow-up study, MK-0822-083 (EudraCT number: 2007-002693-66) .

Hemodialysis patients with low bone density (total hip T-score <-2.5) will be assigned to receive teriparatide (those with histologic confirmation of adynamic bone disease) or ibandronate (subjects with increased osteoclast number on bone biopsy). Follow-up period: one year. A second bone biopsy at the end of the study.

The objective of this study is to evaluate a post-fracture intervention for improving osteoporosis care in older men and women who have suffered a fracture that may indicate the presence of osteoporosis. Although osteoporosis can be identified with a bone mineral density (BMD) test, most individuals with osteoporosis are not diagnosed until they fracture. Post-fracture care often "falls between the cracks" when there is a breakdown in communication between hospital and community, or between specialists and primary care physicians. Often physicians and patients fail to make the connection between an acute fracture and osteoporosis, or the value of secondary prevention strategies. If untreated, there is an extremely high rate of additional fractures after a first osteoporotic fracture. It follows that improving BMD testing and/or treatment in appropriately identified individuals is a necessary step in optimizing post-fracture patient care. Over the next three years we will be testing and optimizing a notification procedure to physicians and/or patients relying upon fracture events reported to the provincial health service (Manitoba Health).

The purpose of the study is to compare the effect of different lower limb amputation surgical procedures on leg bone integrity and rehabilitation outcome.

This is a prospective specimen collection cohort study to evaluate the correlation between serum and urine values of the bone marker of interest, and their association with baseline DEXA scan measures and fracture risk within 6 months. Study samples will be obtained longitudinally. One collection of both serum and urine collection will be obtained. The urine will be collected as second void of day and at the same time the blood collection is drawn. Study will continue for a period or 1 year, with plan to enroll around 40 subjects.

This is a prospective open-cohort study with annual assessment and reporting of descriptive findings from 5 secondary data sources, US Medicare, Optum Research Database (formerly United HealthCare), Scandinavian national health registry databases, including data from Denmark, Sweden, and Norway. The study period will include up to 10 years in each data system depending on data availability. Descriptive statistics will be used to characterize cohorts with respect to patient characteristics and utilization patterns. Person-year adjusted AESI incidence rates will be calculated among postmenopausal women, postmenopausal women with osteoporosis, and exposure cohorts with a final comparative safety analysis. Subsequent sub-studies using US data systems were added to describe men with osteoporosis treated with Prolia and men and women who receive Prolia with glucocorticoid exposure.

Epigenetic modification refers to the change of heritable gene expression occurring in the case of unchanged DNA sequence, including DNA methylation, epigenetic modification, RNAS, chromatin modification, etc. The study found that osteoporosis (OSTEOPOROSIS,OP) with neurological disorders is very common, the risk of fracture of patients increased. It is considered that epigenetic regulation plays an important role in the occurrence and development of OP with neurological disorders. In particular, the role and molecular mechanism of epigenetic modification in OP with neurological disorders are not clear, and the results of clinical studies with different sample sizes are not consistent. (1) Two-way continuous queues,an ambispective cohort study， namely: forward-looking queue method (2017-2027) and Retrospective queue method (2007-2017) were used to understand the effect of epigenetic modification on bone mineral density, bone metabolic Biochemical Index, imaging index and fracture incidence of patients with neurological diseases in outpatients and wards, and to provide basis for further study. To observe the effects of epigenetic modification on cognitive function in two groups of patients (memory scale, life activity Energy meter (ADL) and cognitive scale (MMSE) and clinical physical examination and neuropsychological test, etc., Bone correlation detection (Lumbar and hip bone mineral density T-score, imaging index, bone Metabolic Biochemical Index and fracture incidence index) Influence. Multivariate stepwise regression analysis was performed to eliminate confounding factors, such as age, body mass index (BMI), related risk factors, and internal diseases. The patient's previous information is also analyzed; (2) To find meaningful epigenetic modification from clinical data, the molecular mechanism was studied in depth, and the imaging indexes (X-ray, CT, MRI) and Bone marker Index (serum osteocalcin (OC), total I-type procollagen peptide (TP1NP) were found in the study. Type I collagen hydroxy-terminated peptide beta degradation product (Β-CTX)). The relationship between the reaction epigenetic modification and cognitive function index, image and bone markers and the mechanism model were further established.
