Takayasu's disease: interest in methotrexate treatment

Takayasu's disease is a nonspecific aortic arteritis that affects mostly young women and sometimes children. Usual treatment consists of early and prolonged steroids. Some patients do not respond to this treatment, become steroid-dependent or suffer from side effects. We report a case in which methotrexate proved to be effective.

Methods: A 6-year-old girl presented with Takayasu's disease with elevated blood pressure of renovascular origin. Corticosteroids controlled the inflammatory syndrome but not the renal involvement and stopped the growth. Methotrexate (10 mg/m2/week) resulted in the control of the disease, the reduction of steroids and normal growth.

Conclusions: In Takayasu's disease, steroids should be given as first-line therapy. In case of failure, side effects or steroid dependency, small doses of methotrexate may facilitate the disease's control and weaning from the steroids.
