Management of the patient with Behçet's disease.

Behçet's disease is a vasculitic disorder in which the aetiopathogenetic pathway has not yet been clarified. Many organs and systems may be affected in BD. The causes of the wide-ranged clinical spectrum and the variable severity of involvement, including the kidneys remain to be defined. Behçet's disease should also be considered in the differential diagnosis of AA amyloidosis as well as vasculitic connective-tissue disorders. Specific laboratory tests for the diagnosis and follow up are needed. Only clarification of the aetiopathogenesis of BD can lead to better treatment options.
