Behçet's disease: recent advances in early diagnosis and effective treatment.

Behçet's disease (BD) is a chronic, multisystem, inflammatory disorder that is classified among the systemic vasculitidies. Its cause has yet to be determined, but genetic and environmental factors and immune dysregulation are thought to play a role in its pathogenesis. The diagnosis of the disease and recognition and separation from disorders that may mimic BD may be difficult, especially in areas where the disease is uncommon. Certainty as to the best treatments for the various manifestations of BD is often unclear due to limited randomized controlled trials. However, existing consensus statements and expert opinions should help to guide therapy. This review examines important recent contributions to help the clinician more readily recognize patients with the disease and institute appropriate care.
