Osteoporosis is an important health problem in the rapidly-aging demographic. Fragility fractures are devastating consequences of osteoporosis. The most common treatment approach in osteoporosis is inhibition of bone resorption with drugs like alendronate (ALN). Parathyroid hormone (PTH) stimulates bone formation and is the only anabolic drug available. Dual therapy with ALN and PTH is not as effective as single-drug therapy in preventing fracture. Bone progenitor cells (MSCs) are recruited to sites of bone remodeling when a growth factor called Transforming Growth Factor Beta (TGF-β1) is released from bone. Different osteoporosis medicines may have differing effects on this process. The effects of ALN versus PTH on bone progenitor recruitment in humans are unknown. This is a randomized, clinical trial of ALN, PTH, and calcium and vitamin D in post-menopausal women with low bone mass. Women will be treated for 3 months with ALN or PTH or calcium and vitamin D. Data collected will include bone biopsies for histomorphometry and micro computed tomography (µCT), bone marrow aspirates for molecular studies, peripheral blood to detect circulating bone progenitor cells and dual X-ray absorptiometry. The investigators hypothesize that in humans, PTH will 1) increase bone progenitor number, 2) enhance recruitment of bone progenitor cells to bone resorption sites, and 3) increase bone progenitor number in peripheral circulation. Furthermore, the investigators hypothesize that ALN treatment will have the opposite effect. Understanding the differences in bone progenitor cell activity and recruitment during osteoporosis therapy will provide a mechanistic rationale for effective use of PTH and anti-resorptive drugs in osteoporosis treatment.
Acute Lymphoblastic Leukemia (ALL) is the most common malignancy in children. It accounts for one fourth of all childhood cancers & 74 % of childhood leukemia. Based upon drug registry data, children prescribed more than three courses of systemic glucocorticoids yearly faced a 20% increase in age-adjusted fracture rates. Rapid recovery occurred once glucocorticoids were discontinued, and fracture rates returned to expected for age by 1 year after treatment (Journal Of Clinical Endocrinology & Metabolism 2009). The investigators will study the role of bisphosphonates in the prevention of secondary osteoporosis in children & adolescents treated for ALL in the Children's Cancer Hospital -Egypt.
After vertebroplasty, many patients will suffer from 2nd fracture in the vertebral column. With analyzing of the images done right after the 1st vertebroplasty, we can define the parameters from different imaging and they can be predictors of the future fracture.
The investigators propose a 24 week clinical research trial (12 week observational period followed by 12 week MedSD intervention) with feasibility of diet adoption and markers of bone turnover as the primary outcomes.
The objective of this prospective, observational study in Czech Republic and Slovakia is to describe per country the characteristics of women treated with denosumab in routine clinical practice and the clinical management of these patients during the first 2 years of treatment. In addition, the study aims to collect safety data in the real-life clinical practice settings on adverse drug reactions (ADRs) and serious ADRs.
The aim of the study is to assess the effect of eradication of gut microbiota on 1) glucose metabolism including postprandial plasma responses of the incretin hormones GIP and GLP-1, insulin, C-peptide and glucagon, 2) metabolomic profiles and resting energy expenditure (REE) 3) appetite, satiety, food intake, gastric emptying and gall bladder emptying, 4) levels of markers of bone formation and resorption as well as serotonin, 5) markers of systemic inflammation, and 6) on the (prospective) composition of bacteria in faeces, blood and saliva. Thus, the overall objective is to provide detailed knowledge on the physiological role of gut microbiota combined with bioinformatic analyses of the functional implications of changes in bacteria composition on the level of both species and phylum.
Because the diabetics are fracturing at a younger age than the general population (12), this leads us to believe there are significant factors that lead to fracture in Type 1 diabetes mellitus (DM) other than bone mineral density (BMD). Very little longitudinal data exists on BMD in adults with Type 1 DM and the effects of glucose control on BMD. No longitudinal data exists on pQCT in adults with Type 1 DM. Hypothesis: Adult subjects with diabetes and poor glucose control will lose bone mineral density (BMD) as measured by DXA compared to age and sex matched healthy controls.
In this study, we will provide supplemental vitamin D in postmenopausal overweight/obese women, and hypothesize that it will not affect areal BMD, but will alter bone compartments (trabecular and cortical bone). In addition, higher vitamin D intake will increase serum 25OHD and suppress serum PTH and bone turnover during weight reduction. Secondary outcomes include the influence of vitamin D and weight loss on markers of insulin resistance and on cognitive tests of attention, learning, and memory.
The purpose of this study is to determine if treatment is effective in preventing fractures in women with postmenopausal osteoporosis.
