Biological therapy in polymyalgia rheumatica
1Rheumatology, CHU (University Teaching Hospital), Besançon, France.
Introduction:
Polymyalgia rheumatica (PMR) is an inflammatory rheumatic disease of the elderly, treated mainly with systemic corticosteroids. The frequency of side effects of steroids is high in this aged population and increased due to comorbidities. The use of biological treatments could be of interest in this condition.
Areas Covered:
This review takes into account literature data from the PubMed and clinical trial databases concerning the results of the use of biological treatments in PMR, in terms of efficacy and safety of these treatments.
Expert Opinion:
Current data do not allow us to identify any particular efficacy of the various anti-TNF agents used in the treatment of PMR. Anti-interleukin 6 agents (tocilizumab, sarilumab) have shown consistent efficacy results, suggesting a particularly interesting steroid-sparing effect in the population under consideration. The safety profile appears acceptable. Other biologic targeted treatments are currently being evaluated. Anti-interleukin-6 agents may well have a place in the therapeutic strategy for PMR, particularly for patients with steroid-resistant disease or at high risk of complications of corticosteroid therapy.
