A Canadian researcher has discovered that a molecule generated by vitamin D can improve the healing process of bone fractures.
Bone fractures are very common and sometimes difficult to heal, especially for patients with osteoporosis or glass bone disease. A Montreal doctor, however, would have found a solution that would allow patients to heal more quickly.
Published in the journal Journal of Clinical Investigation, the study by Dr. René Saint-Arnaud, director of research at Shriners Hospitals for Children in Montreal, involved mice prescribed a dose of vitamin D.
This experiment made it possible to discover the mechanism and the benefits of the 24,25 (OH) 2 molecule, secreted by the body during the absorption of the victim B. Present in the rays of the sun as well as in certain foods such as products. Dairy or fish oils, vitamin D accelerates the healing process of bone fractures, because its absorption promotes the concentration of calcium in our body.
Reinforcement of bone callus
To activate the effects of vitamin D, our body proceeds in two steps. During this process, the (OH) 2 molecule produces lactosylceramide, a fatty acid derivative that strengthens the size and stiffness of the callus, thickening of the bone that forms after a fracture and speeds up the process of bone formation. healing.
“We looked at the repair of fractures in these animals and we found that the callus that helps repair the bone was always smaller, more fragile. If we gave back the dihydroxyvitamin D, this deficiency was there. corrected “, explains Dr St-Arnaud to Here Radio Canada.
The conclusions of the study by Professor Saint-Arnaud, who worked on the subject for 15 years before publishing his findings, are therefore encouraging. The next step will be to conduct clinical trials on patients at Shriners Hospital.
3 million French people suffer from osteoporosis
If these future tests prove to be conclusive, they could lead to a valuable avenue of treatment for patients with osteoporosis, an insidious disease that is characterized by excessive fragility of the skeleton, due to a decrease in bone mass and alteration of bone micro-architecture. It would affect 3 million people in France, including 30 to 40% of postmenopausal women.
