Active clinical trials for "Bone Diseases, Metabolic"

The purpose of this study is to determine if soy-derived phytoestrogens (naturally occurring compounds similar to estrogen) can prevent bone loss and other menopausal symptoms in women who have recently gone through menopause. Study hypothesis: Tablets of high-dose, purified soy phytoestrogens spare the normally occurring spinal bone loss and improve biological and other emotional changes of menopause.

Zoledronic acid is a medicine being studied in people with low bone mass. Side effects such as headache, fever, muscle aches, and pains, may occur following the infusion. This study will investigate the use of over-the-counter medicines to improve these symptoms.

The purpose of this study is to evaluate the effect of alfacalcidol 1 µg daily on the number of fallers in postmenopausal, alendronate-treated, osteopenic or osteoporotic women. primary outcome = number of fallers (patients with at least one locomotor fall incl.mixed falls)

Adults with low muscle mass also usually have low bone mass, making them vulnerable to falls, fractures and other injuries. This project will determine the effectiveness of treatment with a ghrelin receptor agonist in improving short term indicators of muscle and bone health in adults with low bone and muscle mass. The results of this trial will inform the design of a larger, definitive randomized trial designed to establish efficacy.

The purpose of this study is to determine whether cholecalciferol supplementation decrease the blood concentrations of hepcidin-25 in hemodialysis patients.

Introduction: The life expectancy and the number of people hitting the old age have increased in recent years. The aging process is accompanied by morphological and functional changes that contribute to reduced functional capacity, increase the number of falls and the appearance of physical limitations. Exercise promotes maintenance of functional autonomy, improving the physical ability of the elderly making it more independent. Objective: To evaluate the effect of a program of muscle strengthening exercises associated with global stretching on balance, fear of falling and functional capacity in elderly women. Methods: This was a non-randomized controlled trial, in which 12 volunteers aged over 60 years were divided into two groups: intervention group (IG, n = 7) submitted to muscle strengthening exercises and stretching, 2 times per week for 12 weeks, and the control group (CG, n = 5), not submitted to the protocol but were educated about physical exercises. Before and after the protocol were evaluated scores of Berg Balance Scale, the Falls Efficacy Scale International (FES-I) and Evaluation of Functional Autonomy Development Group for Latin American Maturity (GDLAM). Data were statistically analyzed within and between groups with a significance level of p <0.05.

Lactobacillus reuteri (L. reuteri) has been widely studied in clinical trials and has probiotic, health-promoting effects in both adults and children, and is safe for human consumption. Animal models indicate that treatment with L. reuteri has positive effects on bone metabolism and bone density. In other animal models of diabetes and the metabolic syndrome, positive effects on blood glucose and weight have been reported. The present double-blind, placebo-controlled, randomized study is designed to investigate if dietary supplementation with L. reuteri twice daily for 12 months has any effect on bone density, body composition, inflammation, or metabolic and endocrine markers in elderly women with osteopenia.

This is a Monocentric, Prospective, Randomized, Open-label, Comparative, Phase IV Study, to compare the effects of Vildagliptin and Gliclazide MR on Markers of Bone Remodeling, Bone Mineral Density and Glycemic Variability in Postmenopausal Women with Type 2 Diabetes. A total of 38 women with documented Type 2 Diabetes and menopause will be enrolled. The active treatment will include a 50 mg dose of vildagliptin OD twice a day. As comparator, gliclazide MR will be administered at a dose of 60 to 120 mg OD once a day.

To evaluate in patients with chronic kidney disease the impact of two dosages of per os vitamin D3 supplementation (cholecalciferol) on large arterial stiffness (evaluated non invasively by pulse wave velocity and high-resolution echotracking system). We will also study arterial calcification (lateral abdominal radiography and echocardiogram), arterial remodeling (high-resolution echotracking system), endothelial function (evaluated by a non-invasive finger biosensor device), and bone remodeling (evaluated by serum biomarkers and bone mineral density).

With the increasing age of people living with HIV/AIDS, age-induced osteoporosis is likely to be compounded by HIV/AIDS and HAART-associated bone loss. Mechanistically, osteoclasts the cells responsible for bone resorption form under the influence of the key osteoclastogenic cytokine receptor activator of nuclear factor kappa-Β ligand (RANKL). The osteoclastogenic and proresorptive activities of RANKL are moderated by its physiological decoy receptor osteoprotegerin (OPG). Imbalance in the ratio of RANKL to OPG alters osteoclastic bone resorption and lead to osteoporosis. Activated T- and B-cells are a major source of RANKL, while normal physiological B-cells are a major source of OPG. T-cells regulate the production of OPG by B-cells. Thus changes in the immune system induced by HIV/AIDS and/or by HAART could affect B-cell and T-cells RANKL and OPG production. Indeed, data from our group shows that in an animal model of HIV/AIDS, the HIV-1 Transgenic rat, the development of osteoporosis is recapitulated as observed in HIV-infected patients, and B-cell OPG and RANKL production are concurrently down regulated and upregulated respectively. Furthermore, preliminary data in HIV-infected subjects suggests dramatic acute upswing in bone resorption following HAART initiation that peaks at 12 weeks and then declines. Based on these findings, the investigators hypothesize HAART associated bone loss is driven by immune reconstitution. Because this effect of HAART is dramatic in magnitude but short in duration, the investigators propose to apply antiresorptive agent (zoledronic acid, reclast®) to specifically spare patients from this dramatic but acute bone damage.
