[Tocilizumab for refractory Takayasu arteritis with aortic aneurysm]. / Traitement par tocilizumab d'une artérite de Takayasu réfractaire avec anévrysme aortique.

ABSTRACT

Takayasu arteritis (TA) is a form of large vessel vasculitis (LVV) which affects the aorta and the main arteries. Many reports showed efficacy of biologic drugs (TNF α inhibitors and interleukin 6 inhibitors) in refractory TA cases. We report the case of a 46-year-old woman with refractory TA complicated by giant aortic aneurysm (AA) and severe hypertension, treated efficacy with tocilizumab (anti-interleukin 6 receptor monoclonal antibody).
