Treatment modalities and ANCA in Takayasu's arteritis.

As other vasculitic-syndromes Takayasu's-Arteritis needs a long-term immunosuppressive therapy in order to control disease-activity. As steroids create many problems in the long run other immunosuppressives should be considered. We report 3 cases treated with low-dose methotrexate. In all patients the arteritis was controlled, steroids reduced or stopped. In the effort to find autoantibodies 16 patients were screened for c-/p-ANCA and neutrophil granular enzymes. In no patient a positive result could be obtained.
