Osteoporosis Clinical Trial
— OstMARKOfficial title:
Osteocalcin in Bone Metabolism and Aging: Effect of Vitamin K Supplementation on Circulating Levels of Osteocalcin, on Glucose and Energy Metabolism and on Muscle Mass and Function
This is an interventional study on nutraceuticals. It is a randomized controlled, open-label, prospective, single-center study that involves the enrollment of 82 patients with osteoporosis and 41 subjects without osteoporosis. The hypothesis the decarboxylated form of Osteocalcin (OC), called GluOC, represents a clinically useful marker for monitoring the effects of supplementation with vitamin K in association with anabolic treatment with teriparatide will be analyzed not only on bone but also on skeletal muscle and energy metabolism in patients with severe osteoporosis.
