NCT ID: NCT02891356 Recruiting - Osteoporosis Clinical Trials

Bone Mass Changes in Anorexia Nervosa Patient Followed During 4 Years

AMOS
Start date: July 2013
Phase: N/A
Study type: Observational

The mechanism of bone loss in anorexia nervosa is complex. Marrow adipose tissue seems to play a role in the regulation of bone metabolism. Adipocytes secrete cytokines and adipokines that either stimulate or inhibit adjacent osteoblasts. This study consist to explore the relationship in anorexia nervosa patients with change in bone mineral density and adipokines like leptin, adiponectin and Préf-1 Bone mineral densities will be measure in 180 anorexia nervosa patients at inclusion and every two years during 6 years. We assess blood and urinary calcium and phosphate levels, bone remodelling markers and adipokines (leptin, adiponectin and Préf-1)

NCT ID: NCT02884401 Recruiting - Clinical trials for Osteoporosis, Postmenopausal

Peri-implant Bone Changes in Post-menopausal Osteoporotic Women

Start date: June 2016
Phase: Phase 4
Study type: Interventional

This is a prospective case series study aiming to evaluate the effect of post-menopausal osteoporosis on the jaw bone around dental implants with a modified titanium surface. The study consists of 8 visits that will be performed within a minimum period of 15 months. Participants will be recruited from the Rheumatology Department and Radiology Department at Barts Health National Health Service (NHS) Trust. Participants will include 20 post-menopausal osteoporotic women with a requirement of a tooth to be replaced. The main objective of this study is to radiographically compare alveolar (jaw) bone changes in width and height after the placement of a dental implant with a hydrophilic (SLActive) surface and 12 months after loading (placement of the crown) it in post-menopausal osteoporotic women.

NCT ID: NCT02861989 Active, not recruiting - Osteoporosis Clinical Trials

Qualitative Study on Osteoporosis Representation and Management in the General Population and in General Practitioners.

QUALIOP
Start date: February 2014
Phase: N/A
Study type: Observational

Osteoporosis (OP) and subsequent fractures (OP fractures) are a source of morbidity and high mortality in the elderly. Despite numerous programs aiming at improving OP care, the prevention, diagnostic and treatment remain suboptimal. Barriers to a better care are multiple, both in the general and at-risk population, and in medical practitioners. Since they do not perceive their susceptibility to OP, people do not see the benefit of prevention. In addition, physicians do not give sufficient importance to OP prevention and care, despite the existence of guidelines. The investigators implemented a qualitative study to explore the knowledge and representations regarding osteoporosis in the general and at-risk population and in doctors in Rhône-Alpes Region, France, using focus groups with women and men and semi-structured face-to-face interviews with general practitioners. Understanding barriers to osteoporosis care in patients and general practitioners will help to set up effective strategies to improve prevention and treatment.

NCT ID: NCT02854722 Not yet recruiting - Clinical trials for Postmenopausal Osteoporosis

The Deferasirox-calcium-vitamin D3 Therapy for Postmenopausal Osteoporosis (PMOP)

PMOP
Start date: August 2016
Phase: Phase 2
Study type: Interventional

In 2006, Weinberg proposed a hypothesis that iron accumulation was a risk factor for osteoporosis. Osteoporosis is a common complication in various diseases, such as hemochromatosis, African hemosiderosis, thalassemia, and sickle cell disease, which all share iron accumulation as a common denominator. Moreover, a 3-year retrospective longitudinal study has shown that iron accumulation was also associated with osteoporosis in healthy adults and especially that it can increase the risk of fractures in postmenopausal women. Based on these observations, iron chelation therapy may have a promising future in the treatment of iron accumulation-related osteoporosis by removing iron from the body. The purpose of this study is to determine whether the addition of the iron chelator, deferasirox, to standard therapy for postmenopausal osteoporosis, is safe and effective.

NCT ID: NCT02832648 Not yet recruiting - Osteoporosis Clinical Trials

Selenium for Musculoskeletal Health

Start date: August 2016
Phase: Phase 3
Study type: Interventional

This research aims to determine whether selenium supplements improve bone and muscle health in older women at risk of osteoporosis (low bone density or weak bones) and fracture (broken bones). Osteoporosis is a major public health problem. One in two women and one in five men over age 50 will have a fracture. Fractures cause pain, disability and reduce life-expectancy. Women with below-average bone density around the time of the menopause might have previously taken hormone replacement (HRT) to prevent osteoporosis, but HRT is much less used now due to side effects. Therefore there is a need for safe, effective and inexpensive preventative interventions for women at risk of osteoporosis. Selenium is a chemical nutrient present in several human proteins, including anti-oxidants. Anti-oxidants may protect against ageing of tissues, including bone, by mopping up damaging reactive oxygen molecules (sometimes called 'free radicals'). Selenium is present in soil, and so is obtained from many foods. However, soil selenium levels are low in Europe, and dietary intake in the UK is below recommended levels. We previously found that women with higher blood selenium levels have stronger bones, but this doesn't prove that giving selenium will improve bone strength. The investigators propose a randomised controlled trial to compare selenium supplements with a placebo (dummy treatment) in women with below-average bone density. The investigators will give selenium (at two different doses) or placebo to 120 women for six months and use blood and urine tests and bone density scans to see if giving selenium does have any effect on bone. The investigators will also do muscle function tests and measurements of free radical molecules.

NCT ID: NCT02822378 Recruiting - Clinical trials for Postmenopausal Osteoporosis

Dried Plums and Bone Health in Postmenopausal Women

Start date: June 2016
Phase: N/A
Study type: Interventional

Postmenopausal women often seek non-pharmacologic interventions for the protection of bone health. Previous research in humans and rodents has indicated that dietary dried plum consumption may be beneficial for bone health, especially in postmenopausal women. However, it is unknown in what quantity dried plums need to be consumed to be of benefit and through what mechanisms dried plums act to impact bone health. Therefore, the purpose of this study is to evaluate the impact of 52 weeks of dried plums consumption in varying quantities on bone mineral density (BMD), bone geometry, and estimated bone strength in postmenopausal women. The investigators also seek to evaluate the mechanisms underlying the effects of dried plums as a dietary supplement by assessing polyphenols and the bioavailable conjugated metabolites in the urine of postmenopausal women taking different doses of dietary dried plums. The investigators aim to further investigate the mechanisms of dried plum action on bone by measuring markers of bone metabolism in response to dried plum consumption.

NCT ID: NCT02815566 Not yet recruiting - HIV Clinical Trials

Bone Health in Aging HIV Infected Women

Start date: September 2016
Phase: Phase 4
Study type: Interventional

Design: Double-blind placebo controlled randomised multicenter international strategic trial of older women on combination antiretroviral therapy (cART) containing tenofovir-emtricitabine (TDF/FTC) with HIV RNA suppression for > 6 months to : 1. Immediate switch of TDF/FTC to tenofovir alafenamide-emtricitabine (TAF/FTC) while continuing the third antiretroviral agent.; 2. Delayed switch; with switch of TDF/FTC to TAF/FTC at 48 weeks while continuing the third agent. Follow up of all subjects to 96 weeks. Subject Population: The anticipated sample size is 128 HIV infected women aged 45-55 years (peri or early post menopause). . Primary endpoint: Percentage change from baseline bone mineral density (BMD) at the lumbar spine at weeks 48 and 96. Secondary Endpoints: BMD change at hip, trabecular bone score, estimated bone strength by high resolution peripheral quantitative computerized tomography (HR-pQCT), muscle quality, geriatric assessment; biomarkers of bone, immune activation and inflammation; HIV viral suppression; safety, lipid and renal function, cardiovascular risk scores at weeks 48 and 96. Expected Outcomes: To determine if a switch from TDF/FTC to TAF?FTC improves BMD to a degree correlating with a decreased risk of fragility fracture in aging HIV infected women. Secondary outcomes will assess bone strength using new imaging modalities, timing of switch, and renal health. This data will be used by health policy makers and providers to determine the proper use of TAF?FTC in the aging HIV population.
