Immune resolution mechanisms in inflammatory arthritis.

The past two decades have witnessed major advancements in the clinical management of inflammatory arthritis, with new treatment strategies in some cases providing a marked improvement in patient outcomes. However, it is widely accepted that current strategies do not provide the 'total therapeutic solution', in view of the proportion of patients who do not respond to therapy, the important incidence of adverse effects and the development of an immune response against antibodies or fusion proteins used therapeutically. Moreover, although some therapeutic approaches can effectively bring about an end to inflammation, mechanisms to promote the recovery and/or repair of damage are required. Harnessing the concepts and mechanisms of the resolution of inflammation is a new approach to the treatment of inflammatory pathologies; this approach could help address the unmet need for new therapeutic approaches that not only control but also revert the course of inflammatory rheumatic diseases.
