Objectives: To update the 2006 Italian Society for Rheumatology recommendations for the use of biologic (TNF-α blocking) agents in the treatment of psoriatic arthritis (PsA).
Methods: A panel of experts performed a literature search and identified the items that required updating on the basis of new published data. A draft of the updated recommendations was circulated to a group of Italian Rheumatologists with a specific expertise in PsA and in therapy with biologic agents, and their suggestions were incorporated in the final version.
Results: A consensus was achieved regarding the initiation and the monitoring of anti-TNF-α agents in PsA. Inclusion and exclusion criteria were defined and specific recommendations were made for patients with psoriatic peripheral synovitis, spondylitis, enthesitis, and dactylitis, respectively. We also specified criteria for assessment of response to treatment and for withholding and withdrawal of therapy.
Conclusions: These recommendations may be used for guidance in deciding which patients with PsA should receive biologic therapy. Further updates of these recommendations may be published on the basis of the results of new clinical studies and of data from post-marketing surveillance.
