[Treatment of psoriatic arthritis : Are there differential indications?]

Abstract

Psoriatic arthritis (PsA) is a very heterogeneous immune-mediated disease that usually involves skin and joints but can also affect entheses and extra-articular structures during the disease course. Furthermore, it can also be linked with other associated diseases. Therefore, the individualized selection of an effective and patient-oriented treatment must be carried out taking the extent of various manifestations of the PsA itself and also of other influencing factors into consideration. Various recommendations for selection and control of the suitable treatment of PsA 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 recommendations that are frequently used and internationally acknowledged. Both recommendations were updated in 2016. Specific German treatment recommendations are currently missing. In analogy to the treat-to-target strategy for rheumatoid arthritis, at least minimal disease activity (MDA) should be achieved in PsA patients with the use of specific therapeutic interventions if remission as the maximum therapeutic goal cannot be reached. New treatment options, which target different specific molecules, offer possibilities for a more differentiated personalized medicinal treatment for improvement of the care of PsA patients. This particularly applies to a focus on personalized strategies for optimal treatment of various manifestation forms and patterns.
