Aiming for remission in psoriatic arthritis

Psoriatic arthritis is a complex and heterogeneous disease that can manifest in several different ways, and is known to have variable outcomes. Although several definitions of remission have been proposed, none are validated, and few encompass all aspects of the disease. On the other hand low, or minimal, disease activity is an achievable target in psoriatic arthritis and using this treatment strategy results in improved clinical outcomes. Whatever target is chosen, it is clear is that it is not sufficient to measure only the articular involvement in this disease, but to define remission and low disease activity in terms of the major manifestations of this disorder.
