Rhumatologie. Denosumab: le joker du rhumatologue [Denosumab, the rheumatologist's joker?]

The number of molecules acting on bone turn over rapidly increasing. The idea to use them on bones erosions is not new, however this year a new molecule confirms the suitability of such an approach with the demonstration of efficency in both postmenopausal osteoporosis as well as in the prevention of bone erosions in rheumatoid arthritis. Denosumab, a human monoclonal antibody against RANKL (Receptor Activator of Nuclear factor-KB ligand), decreases the fracture risk in postmenopausal osteoporosis and prevents new bone erosions in rheumatoid arthritis. Of simple use, it appears to act rapidly, to be efficient with a sustain benefit. The tolerance seems excellent, and now we'll have just to wait for its licensing.
