NCT ID: NCT03878732 Recruiting - Clinical trials for Osteoporosis, Postmenopausal

Bindex for Osteoporosis Diagnostics

Start date: March 11, 2019
Phase:
Study type: Observational

Osteoporosis is a disease that leads to impaired skeletal strength and increased fracture risk. Among 200 million osteoporotic patients most are diagnosed only after several fractures. Furthermore, the progressively aging population will increase the prevalence of osteoporosis. It is estimated that over 75% of osteoporotic patients are not diagnosed and does not receive treatment for their condition. Bindex ultrasound device has been developed and validated in Caucasian female population. In this study, diagnostic thresholds for density index as determined with Bindex will be evaluated in two different ethnic populations.

NCT ID: NCT03832088 Recruiting - Sarcopenia Clinical Trials

Sarcopenia And Balance In Postmenopausal Osteoporosis

Start date: August 1, 2018
Phase: N/A
Study type: Interventional

The study was performed on 53 postmenopausal osteoporosis patients who presented to our osteoporosis outpatient clinic. Following written informed consent, patients were evaluated for sarcopenia according to the sarcopenia algorithm proposed by the European Working Group on Sarcopenia in Older People (EWGSOP). Algorithm parameters were walking speed, muscle strength and muscle mass measurements. We used Timed Up and Go Test (TUG) for evaluation of walking speed, Jamar Hand Dynamometer for muscle strength assessment, and calf circumference for muscle mass measurement. Balances of the patients were evaluated with Berg Balance Scale (BBS) and functional skills were evaluated with the Timed Up and Go Test (TUG). Other clinical parameters (age, body mass index (BMI), 25OHvitD level, menopause age, fall within the last year, fracture history, history of fracture in mother) were questioned.

NCT ID: NCT03816449 Recruiting - Clinical trials for Influence of Specifically Designed Exercise Program on Serum Matrix Metalloproteinases and Functional Status in Women With Postmenopausal Osteoporosis

Influence of Exercise Program on Serum Matrix Metalloproteinases and Functional Status in Women With Postmenopausal Osteoporosis

Start date: January 1, 2018
Phase: N/A
Study type: Interventional

Osteoporosis is a chronic, systemic and the most frequently metabolic bone disease, characterized by low bone mass and microarchitectural remodeling of bone, which results in a greater fragility of the bone and risk of fracture. With the purpose of explaining the patophysiological mechanisms responsible for osteoporosis, it is necessary to determine the factors that influence on the activity and differentiation of osteoblasts and osteoclasts, as well as their dynamic change depending on the use of an appropriate treatment. According to the recommendations of the International Association for osteoporosis (the National Osteoporosis Fondation- NOF) the treatment of osteoporosis includes pharmacological and non-pharmacological treatment of. Pharmacological includes a range of different drug, where the bisphosphonates, non-hormonal antiresorptive drugs, present gold standard in the treatment of postmenopausal osteoporosis . Non-pharmacological treatment implies the daily physical activity and the specific exercise program, for the purpose of slowing or stopping the loss of bone mass, improve balance, and reduce the risk of falling and fractures. It is known that the mechanical loading of the bone has to be strong enough to achieve the effect of osteogenesis. The load due to the long bones of gravity and the tension force produced by the muscular activity, are the natural stimulus for maintenance of bone mass and muscle strength. This can be achieved by practice involving the activities in which the net mass of the body constitutes an additional load (so-called. "Weight-bearing exercises"), as well as exercise resistance from. Exercise with one's own mass include actions to counter gravity in an upright standing position, and then may be a stronger (high-impact) collides with the substrate (e.g., jumping) and the lower (low-impact) collides with the substrate (e.g., walking). Aerobic exercise, especially walking, is the most common type of intervention because of the ease administration and safety. Resistance training is another effective type of exercises that can affect the maintenance or improvement of bone mineral density, with the most frequently applied with the combination of the dynamic resistance exercises that engage multiple joints, large groups of muscles, and the burden on the hips and the spine. In order to strength training, with the aim of maintaining and stimulating bone mineral density had the best effect, it is necessary to include the basic principles of specificity, load and progression. Training should be directed to the adaptation of a specific part of the body, should be sufficiently intense to and beyond the common load, and a variety of progressive enough. Progression loads should be slow and gradual to avoid injury. We assumed that this type of exercise can be achieved by changing the activity of serum matrix metalloproteinases. It has been proven that in the process of remodeling of the extracellular matrix of the bone, matrix-metalloproteinases play an important role, both, the occurrence of bone as well as in pathological processes of bone resorption . Also, it is known that metalloproteinases, particularly the MMP-2 and MMP-9 play a significant role in the development of skeletal muscle recovery from injury or remodeling of the same after exercise.Taking into account the results of the latest studies on the role of metalloproteinases in the development and remodeling of bone, also and muscle, we assumed that the value of metalloproteinases could serve as markers for early assessment of treatment response of patients with osteoporosis. In our study, we will follow the changes of serum levels of metalloproteinases as well as tissue inhibitor of matrix metalloproteinases 1 (TIMP-1) in the serum of patients with postmenopausal osteoporosis, which have prescribed bisphosphonates, before and after application to the specifically designed exercise program . A functional genetic polymorphisms (PM), by modulating the expression of the MMP can be associated with a differential response to the application of our patients of the same exercise program. Specifically designed exercise program in patients with osteoporosis, which affects the increase in BMD and muscle strength, can be associated with a specific MMP genotyp . In our research we will follow the influence of polymorphisms of the mentioned metalloproteinases on the efficacy of the treatment (the specifically designed exercise program ) in patients with postmenopausal osteoporosis.

This study evaluates how patients treated with denosumab or zoledronic acid for osteoporosis may change the number of peripheral osteoclast precursors and osteoclast activity, and how that may be associated with changes in bone mass.

NCT ID: NCT03761979 Completed - Osteopenia Clinical Trials

Safety and Pharmacokinetics of Orally Administered Strontium L-Lactate in Healthy Adults

Start date: March 9, 2017
Phase: N/A
Study type: Interventional

No clinical trials have evaluated strontium L-lactate (SrLac), the strontium salt of the L-enantiomer of lactic acid. Therefore, this clinical study was conducted to obtain general safety and pharmacokinetic (PK) information following acute oral intakes of three doses of SrLac by healthy adults. The data provided valuable comparisons with the pharmacokinetics of other strontium salts that are in clinical use and allowed determination of the dose of SrLac that will be useful for the management of bone health.neficial for the treatment of low bone density of osteoporosis and osteopenia.

Milk Protein and Bone Health in Postmenopausal Women

OSTEOMILK
Start date: October 22, 2018
Phase: N/A
Study type: Interventional

The process of bone remodeling exhibits pronounced diurnal pattern that is important for bone health. A balanced rate of bone resorption is required to maintain bone health, a balance that can be disturbed during the life-cycle to effect net rate of formation (as occurs during growth and development to adulthood) or net resorption (as occurs, for example, during the menopause). Bone turnover is a nutritionally modulated process and the investigators believe a milk-based protein supplement (MBPS) can modulate beneficially the rate of bone resorption over the time period when bone remodeling is most active i.e. late evening/overnight. In this novel approach to the timing of nutrient ingestion, the proposed nutrient intervention seeks to modify (reduce) the rate of bone resorption and promote the rate of bone formation to the benefit of bone health in this at risk population..
