[Psoriatic arthritis : Current therapeutic standards]

Abstract

Psoriatic arthritis (PsA) is a heterogeneous immune-mediated disease that usually involves the skin and joints but can also affect the entheses, spine and other extra-articular structures. Furthermore, it can be coupled with associated comorbidities. The selection of a patient-oriented and effective therapy is based on the extent of various manifestations of the disease as well as further influencing factors. Various recommendations for selection and control are available for deciding on a suitable treatment. The recommendations of the European League Against Rheumatism (EULAR) and the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) are most frequently used and are internationally acknowledged. Both recommendations were updated in 2016. German treatment recommendations are currently lacking. In analogy to the treat-to-target strategy in the treatment of rheumatoid arthritis, minimal disease activity should at least be achieved with the therapeutic intervention used if remission as the therapeutic target cannot be reached. New treatment options, which target different molecules, provide possibilities for a more differentiated therapy for improvement in the treatment of PsA patients.
