NCT ID: NCT05350579 Terminated - Inflammation Clinical Trials

Yogurt Supplementation to Alter Bone Biomarkers, the Gut Microbiota and Inflammation in Older Adults

Start date: March 28, 2019
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05127681 Terminated - Osteoporosis Clinical Trials

Bone Microarchitecture in Men With Hemophilia

HEMOS
Start date: August 1, 2023
Phase: N/A
Study type: Interventional

Hemophilia A and B are hereditary sex-linked deficiencies of coagulation factors VIII and IX characterized by bleeding. Their modern therapy increases life expectancy and risk of age-related diseases, e.g., osteoporosis. Hemophilia-specific risk factors impair formation of peak bone mass and accelerate bone loss. Fractures are more frequent in hemophilic men vs. age-matched men and induce bleeding which is aggravated by manipulations and surgical intervention. The hypothesis of this study is that hemophilic men have poor bone microarchitecture (assessed by High-resolution peripheral quantitative computed tomography (HR-pQCT)) related to an imbalance between bone formation and resorption (assessed by bone turnover markers (BTM) and bone biomarkers). The study aims to assess the difference in low trabecular number (Tb.N) at the distal radius between hemophilic men (cases) and age- height-weight-ethnicity and smoking-matched healthy men (controls). Correlation between BTM and Tb.N will be also studied. Biologic markers of bone remodeling (C-terminal telopeptide of type I collagen (PINP), N-terminal propeptide of type I procollagen (CTX-I), periostin) will be studied.

NCT ID: NCT04469374 Terminated - Clinical trials for Osteoporosis, Postmenopausal

Menopause Osteoporosis and Bone Intervention Using Lifestyle Exercise.

MOBILE
Start date: December 1, 2019
Phase: N/A
Study type: Interventional

Aim: to examine the effect of an exercise intervention for preventing osteoporosis among postmenopausal women. Objectives: To examine whether mean values for Broadband Ultrasound Attenuation (BUA) using Quantitative Ultrasound (QUS) among postmenopausal women following an eight-month exercise intervention (and at 3-month follow up), will be significantly higher than those obtained pre-intervention. To examine whether mean BUA values among postmenopausal women following an eight-month exercise intervention (and at 3-month follow up) will be significantly higher than mean values obtained from participants in a control group undertaking sham exercises for an equivalent duration. To examine the feasibility of the eight-month exercise intervention for a potential larger study (larger sample size, increased number of trial arms and increased outcome measures), in terms of recruitment, adherence, perceptions, barriers, and acceptability.

NCT ID: NCT04275011 Terminated - Osteoporosis Clinical Trials

Bone Response to Exercise in Women on Antiresorptive Medications

BRRIE
Start date: January 2, 2020
Phase: N/A
Study type: Interventional

Performing resistance training and impact exercise at a moderate to high intensity may help prevent bone loss. However, medications used to treat bone diseases such as osteoporosis reduce the activity of bone cells. The investigators are unsure whether bone cells will still respond to exercise in people on osteoporosis medications. Therefore, investigators have designed a study to compare bone response to moderate-high intensity exercise that involves resistance training and impact exercise versus posture and low intensity balance exercises. Women taking osteoporosis medication will be equally and randomly assigned to one of the exercise groups. There will be 23 participants per group and both exercise programs will be performed over a span of 6 months, twice weekly, for approximately 30-45 minutes per session. Investigators will measure sclerostin, a bone-related protein found in the blood, to see if there are any changes after 3 months of training. Higher levels of sclerostin may result in greater bone breakdown. It is expected that the moderate-high intensity exercise program will decrease sclerostin levels more than low intensity training. Further, changes in sclerostin levels during the 6-month exercise intervention will be explored. The effects of the exercise program on other bone markers in the blood, physical ability, and quality of life will be reported. The willingness of the participants to perform the exercise program and the safety of the exercises provided will also be assessed.

NCT ID: NCT04271605 Terminated - Clinical trials for Osteoporosis, Postmenopausal

Intervention on Osteoporosis and Chronic Kidney Disease-mineral and Bone Disorder (CKD-MBD)

Start date: February 14, 2020
Phase: N/A
Study type: Interventional

Older adults having chronic kidney disease (CKD) have a higher rate of fracture than those without chronic kidney disease. Osteoporosis and chronic kidney disease mineral and bone disorder (CKD-MBD) are risk factors for skeletal fractures. In addition, CKD-MBD is also a risk factor for cardiovascular disease. Pharmacological and non-pharmacological therapy are both important to prevent complications of chronic kidney disease and osteoporosis. Therefore, a prospective intervention study is purposed to investigate the effect of a multifaceted intervention including exercise, diet modification, and pharmacological therapy on their outcomes. Patients who are older than 50 years old and have chronic kidney disease G3-G4 (estimated glomerular filtration rate > 20 ml/min per 1.73 m2) with a high risk of fracture (screening by Fracture Risk Assessment Tool (FRAX®)) are enrolled. Baseline questionnaire, clinical, laboratory and radiological examination are performed. If CKD-MBD or osteoporosis are revealed, the intervention will be given accordingly. All examinations will be repeated every 3 months, except bone mineral density and x-ray film for the spine to investigate the effect of the intervention. After one-year, primary outcomes including mortality, cardiovascular events, subsequent fracture, and fall rate will be examined. The secondary outcomes include changes in biochemistry laboratory data before and after interventions (pharmacological therapy and lifestyle modifications). The bivariate analysis will be performed using the t-test or Mann-Whitney U test for continuous variables with normal or non-normal distribution, respectively. Chi-squared test for categorical variables will be used to test correlations between baseline characteristics, change of laboratory results and outcomes. The paired t-test will be used to examine the difference between before and after the interventions. Stepwise multivariate logistic regression models will be used to identify the correlates of outcomes after adjusting for potential confounders.

NCT ID: NCT03966261 Terminated - Healthy Clinical Trials

The Role of Incretins in Bone Remodeling in Humans

INCREMOS
Start date: March 10, 2020
Phase:
Study type: Observational

The role of incretins (GIP and GLP-1) on cells and bone tissue has been shown in cellular and animal studies. In humans, the role of these hormones is mainly studied in the pathophysiology of diabetes, their effect on bone is unknown. The serum incretin concentration is low and increases rapidly after a meal. This increase is brief, incretins being rapidly degraded by dipeptidylpeptidase 4 (DPP-4). The dosage of these hormones is complex and the basal "normal" serum concentrations and after feeding in healthy subjects are unknown. Before any study on the effect of incretins on bone remodeling in humans, it is necessary to establish physiological concentrations of incretins in healthy subjects. The aim of this study is to estimate physiological concentrations of incretins in healthy subject.

The Effects of 12-months of Denosumab on Bone Density in Prevalent Kidney Transplant Recipients

ProliaKTx
Start date: January 16, 2020
Phase: Phase 2
Study type: Interventional

This is a Phase 2 Multi-Center Clinical Trial (safety and effectiveness trial) in 60 patients (40 denosumab; 20 placebo) who have had a kidney transplant for 12-months or longer with more than 30% of kidney function. The investigators will test whether denosumab safely improves bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA) and improves bone strength by high resolution peripheral quantitative computed tomography (HR-pQCT) in the subset of patients recruited at Columbia University Irving Medical Center. These data will inform the development and execution of a larger trial to test if denosumab prevents fractures in kidney transplant recipients.

NCT ID: NCT03812380 Terminated - Osteoporosis Clinical Trials

Averting Complications of Proton Pump Inhibitor Therapy by Effervescent Calcium Magnesium Citrate

Start date: January 1, 2019
Phase: Phase 3
Study type: Interventional

Proton pump inhibitors (PPIs) are widely used for the control of gastric ulcer-gastritis, erosive esophagitis (gastroesophageal reflux disease), peptic ulcer disease (duodenal ulcer), and heartburn. Despite their efficacy, their use has been implicated in possibly causing fragility fractures (osteoporosis), hypomagnesemia (magnesium deficiency) and increased risk of chronic kidney disease (CKD). The current trial represents the investigators' ongoing effort to discern whether these complications could be averted by effervescent calcium magnesium citrate (EffCaMgCit).
