Takayasu's arteritis: therapeutic strategies.

Takayasu's arteritis (TA) is a chronic inflammatory disease of unknown origin, primarily affecting the walls of large vessels. TA can be a severe and life-threatening disease, and has relevant consequences for the patient's life-style. Mortality and morbidity depend on both the direct effect of the vascular lesions and the following complications. The mainstay of TA therapy is based on the use of glucocorticoids alone or in association with cytotoxic drugs. Unfortunately, in the majority of cases, only a partial control of the disease is obtained. The therapeutic strategy may vary in different countries, and in Japan, where the disease was first described, high dose glucocorticoids are preferred to glucocorticoids in association with cytotoxic agents. We present here a review of the pharmacologic strategies most commonly adopted for the treatment of TA in America, Italy and Japan, together with our experience on 31 TA patients, who have been followed in the last two decades. The discussion is also open on which criteria are more accurate in measuring disease activity.
