Two Takayasu arteritis patients successfully treated with rituximab.

Description

Takayasu arteritis (TA) is a rare form of chronic large vessel vasculitis of unknown origin involving the aorta and its major branches. Recently, the involvement of B lymphocytes in TA has been suggested, and active refractory TA patients were successfully treated with B cell depletion therapy (BCDT). We report two cases of patients with TA successfully treated with anti-CD20 monoclonal antibody (rituximab). The favorable outcome of rituximab treatment in our patients also support the view that BCDT can be a useful option for refractory TA, and its potential should be evaluated in controlled trials.
