Infliximab therapy in pediatric Takayasu's arteritis: report of two cases.

Takayasu arteritis (TA) is a chronic vasculitis of unknown etiology. Experience with anti-tumor necrosis factor alpha (anti-TNF) agents in difficult-to-treat patients with TA is limited and refers to adult patients. Here, we present two cases of pediatric TA treated with infliximab, in which clinical remission was observed. Anti-TNF treatment represents a useful therapy in pediatric Takayasu arteritis too, especially to avoid the risk of long-term corticosteroids toxicity.
