Filter by:Non-interventional observational prospective follow-up study of cohorts of patients with Previous diagnosis of Osteoporosis with high risk of fractures, with/without previous fractures and treatment with bone formers (biosimilar or original Teriparatide), who meet all the inclusion criteria and exclusion, with prior information and signing of prior informed consent documents.
Osteoporotic fracture is a common public-health problem in the whole world. Although postfracture usage of anti-osteoporosis medications, may reduce mortality, recent results have been inconsistent. The investigators aim to examine associations between osteoporosis medication and mortality in older adults and any type of fracture patients. The investigators also aim to discuss the pleiotropic effects of different types of anti-osteoporosis medications.
Denosumab(Dmab) is a monoclonal antibody that inhibits the receptor-activator of nuclear factor kappa-B ligand. It improves bone density and reduces fractures by inhibiting osteoclast recruitment and differentiation. Although the FREEDOM trial showed Dmab increase bone mineral density for ten years, the effect was reversible. When Dmab is discontinued, the rebound phenomenon, the bone mineral density returns to the pre-treatment value, and multiple vertebral fractures may occur. Recently, a guideline to administer bisphosphonates sequentially when Dmab is discontinued has been published. In several studies, Zoledronic acid prevented bone loss after denosumab discontinuation with a single administration in Dmab short-term(less than 2.5years) users, but in Dmab long-term(more than 2.5years) users, zoledronic acid did not fully prevent loss of BMD. Our study tried to evaluate that ZOL administration twice for six months apart in long-term Dmab users is not inferior to a single administration of ZOL in Dmab short-term users.
This is a randomized, double-blind, international multicentre, parallel-controlled phase III clinical study. The study plans to enroll 478 postmenopausal women with osteoporosis at high risk of fracture, whom will be randomized at 1:1 to either the experiment group (HLX14) or the control group (Prolia®) based on stratification factors (BMI (< 25, 25-30, > 30) and geographic region (Asian or non-Asian)). The study includes screening period (28 days), treatment period (total 546 days, contain treatment period 1: D1-D364, treatment period 2: D365-D546), and an end-of-study visit (D547).
Caribbean Latino adults are a vulnerable population at risk for developing osteoporosis. In addition to lifestyle factors, such as dietary intake, the investigators hypothesize that a unhealthy gut microbial environment coupled with high inflammation contributes to the risk of developing osteoporosis. There has been little research conducted on mechanisms underpinning how a low-intensity dietary intervention, including supplementation with daily yogurt, can affect the gut health of Caribbean Latino adults. The study objectives are to: 1) determine whether daily yogurt supplementation reduces bone turnover (biomarkers of overall bone health) and inflammation compared to a control group that maintains their usual diet (void of yogurt); and 2) collect preliminary data on the effects of daily yogurt supplementation on the gut microbiome compared to diet control group.
To evaluate the effect of 12 months of supplementation with a probiotic (probiotic plus prebiotic; 2 capsules per day) on relative change (%) in total volumetric bone density (measured using high resolution peripheral quantitative computed tomography [HR-pQCT]) of the distal tibia.
Recently, an increase in the prevalence of hyperparathyroidism and hypovitaminosis D in postmenopause women has been occurring in Mexico and the world. Chronic exposure to the parathyroid hormone (PTH) is catabolic for the bone, worsening the state of osteoporosis. However, it is unclear whether these conditions could significantly improve bone mineral density (BMD). In the present work, it was shown that the resolution of hyperparathyroidism in postmenopausal women improves osteoporosis.
Osteoporosis is defined as a systemic disease of bone mineralization, characterized by a decrease in bone mineral density that causes bone fragility and increases the risk of fractures during menopause. Recently, a high prevalence of hypovitaminosis D has been found worldwide, which could trigger a state of secondary hyperparathyroidism that can worsen the state of postmenopausal patients with osteoporosis. An open-label, clinical trial was conducted in Mexican women with postmenopausal osteopenia-osteoporosis to determine the efficacy of the combined treatment with risedronate and high-dose vitamin D in improving bone mineral density, hyperparathyroidism, and hypovitaminosis D.
This is a randomized, double-blind, multicenter, parallel-arm, Phase 3 study to compare the efficacy, PK (Pharmacokinetic), PD (Pharmacodynamic), safety, and immunogenicity of Bmab 1000 and Prolia® in postmenopausal women with osteoporosis
China has gradually entered an aging society, and the incidence of osteoporotic fractures is increasing rapidly. Although the harm of osteoporotic fracture is huge, its diagnostic rate in China is still low. China still lacks a national osteoporotic fracture registration system, which has been established in many countries. The purpose of this study is to establish a Chinese osteoporotic fracture registration network platform (CORN), which will be helpful for the long-term comprehensive management of osteoporotic fracture population in China. This platform will help to establish a large prospective clinical cohort database of osteoporotic fractures and high-risk population in China.
