Effect of Vitamin K Supplementation on Circulating Levels of Osteocalcin on the Bone Metabolism and Aging

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

Reason given: Logistics/management problems at the recruiting center

Brief summary (registry, in English)

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.

Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

Prior treatment

  • ongoing therapies: glucocorticoids, antiepileptics, aromatase inhibitors and similar gonadotropin-releasing hormone (GnRH, contraindicated for teriparatide).
  • ongoing therapies: glucocorticoids, antiepileptics, diphosphonates, teriparatide, denosumab, statins, oral or injective hypoglycemic agents, aromatase inhibitors, similar GnRH or other oncological therapies

Lab values

  • causes of secondary osteoporosis: current glucocorticoid therapy, active and uncontrolled rheumatic diseases, endogenous hypercortisolism, uncontrolled hyperthyroidism or hypothyroidism (except known hypothyroidism well compensated with L-thyroxine), chronic renal failure (IRC) with glomerular filtration rate (GFR) <30 ml / min, multiple myeloma, liver failure (chronic liver disease of CHILD class B and C), heart failure (New York Heart Association, also said NHYA) NHYA> 2, active neoplasms, type 1 and type 2 diabetes mellitus
  • diagnosis of IRC with estimated GFR <30 ml / minute, liver failure (chronic liver disease of CHILD class B and C), heart failure with NHYA> 2 , active neoplasms, endocrinopathies (except known hypothyroidism well compensated with L-thyroxine ), type 1 and type 2 diabetes mellitus.

Other

  • diagnosis of osteoporosis (according to World Health Organization, WHO) T-score <-2.5 standard deviation (SD), at any site evaluated with ''Dual-Energy X-ray Absorptiometry'' (DXA)
  • diagnosis of sarcopenia (according to ''Appendicular Skeletal Muscle Mass'', ASMMI) ASMMI <7.59 kg / m2 for males and 5.47 kg / m2 for females evaluated with DXA
