Tocilizumab in cranial and extracranial giant cell arteritis: a national multicenter study of 471 cases.

Objective: The spectrum of giant cell arteritis (GCA) includes different vascular phenotypes. Tocilizumab (TCZ) is the only biologic currently approved regardless these phenotypes. We aimed to assess the effectiveness of TCZ in different phenotypes.

Optimisation of tocilizumab therapy in giant cell arteritis. A multicentre real-life study of 471 patients.

Objectives: Tocilizumab (TCZ) is the only biologic therapy approved for giant cell arteritis (GCA). There is general agreement on the initial/maintenance dose, duration of TCZ therapy is not well established. In GiACTA trial, after one year on TCZ, most patients had GCA relapse after withdrawal.

Tocilizumab in visual involvement of giant cell arteritis: a multicenter study of 471 patients.

Background: Visual involvement is the most feared complication of giant cell arteritis (GCA). Information on the efficacy of tocilizumab (TCZ) for this complication is scarce and controversial.

Objective: We assessed a wide series of GCA treated with TCZ, to evaluate its role in the prevention of new visual complications and its efficacy when this manifestation was already present before the initiation of TCZ.
