title: Psoriatic arthritis: therapeutic principles.
abstract: From the dermatologic point of view, psoriatic arthritis (PsA) was seen for a long time as a rare complication of psoriasis. Recent studies, however, reveal a high prevalence of PsA among patients with psoriasis, and the impact of PsA due to chronic inflammation of peripheral joints, axial joints, and periarticular structures leading to radiologic progression, functional impairment, and reduction in quality of life is well recognized. Substantial improvement in understanding immunopathology of PsA has led to a variety of new therapeutic options. This article reviews the current therapeutic principles for PsA.
