Short-term effect of leflunomide in patients with Takayasu arteritis: an observational study

Abstract

This is the first open-label study to demonstrate improvement in disease activity and acute phase reactants with 20 mg/day of leflunomide in TA patients who were refractory or intolerant to conventional therapy with corticosteroids and immunosuppressive agents. Leflunomide was safe and a steroid-sparing effect was observed. A double-blind controlled study is desirable to confirm this finding.
