Vitamin D Supplementation in Postmenopausal Women With Osteoporosis: Proposal of a Therapeutic Regimen in Practice
This trial is active, not recruiting.
|Treatments||vitamin d3, 100 000 iu weekly, 4 times, 25 oh vitamin d serum concentration measurements|
|Sponsor||University Hospital, Caen|
|Start date||June 2011|
|End date||December 2015|
|Trial size||120 participants|
|Trial identifier||NCT02518763, 08-090|
The vitamin D deficiency (25OHD) is very common and affects about 80% of the population of French osteoporotic women over 50 years . It contributes significantly to bone fragility and consequently the risk of fracture. To remedy this deficit, it is necessary to provide a suitable and sustainable supplementation. Changes in vitamin D deficiency ranging from undetectable to a 25OHD value very close to 30ng / ml lead to differences in therapeutic regimens, specific to each clinician in the absence of precise data in the literature. No consensus on supplementation dosages and methods have been proposed so far. Also, given the frequency of vitamin D deficiency including osteoporosis observed in the population, it became necessary to establish a single, uniform regimen for all patients with osteoporosis
