[Treatment strategies in psoriatic arthritis].

Psoriatic arthritis is a heterogeneous immune-mediated disease that usually involves skin and joints but can also affect entheses and extraarticular structures in the disease course. In addition, associated diseases must be considered when choosing the appropriate therapeutic strategy. Different recommendations for treatment of psoriatic arthritis are available for clinical use. The recommendations of the European League Against Rheumatism (EULAR) and the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) are the two internationally accepted guidelines frequently used to assist therapeutic decisions in clinical practice. New targeted treatment options developed based on a better knowledge of critical pathogenic pathways, will enlarge our armamentarium for optimized pharmacotherapy of psoriatic arthritis and improve personalized patient care.
