Title: Vasculitis Poster III: Immunosuppressive Therapy in Giant Cell Arteritis and Polymyalgia Rheumatica
Session Type: ACR Poster Session C
Session Time: 9:00AM-11:00AM
Background/Purpose: Giant cell arteritis (GCA) is a large vessel vasculitis with a special predilection for extracranial branches of the external carotid artery. Among its most fearsome complications is visual affectation. Tocilizumab (TCZ) is a monoclonal antibody directed against the interleukin 6 receptor that has shown utility in the treatment of GCA. Our aim was to assess the evolution of visual clinic in patients with GCA treated with TCZ.
Methods: Retrospective multicenter study on 20 GCA patients with visual involvement in treatment with TCZ. The efficacy of this drug on visual symptoms was evaluated.
Results: We assessed 20 patients (14 women and 6 men) with a mean age ± SD of 73.7 ± 10.1 years with GCA and visual symptoms. In total there were 23 affected eyes. The symptoms reported were: unilateral blindness (n = 6), unilateral blurred vision (n = 6), unilateral amaurosis fugax (n = 3), unilateral hemianopsia (n = 2), bilateral blindness (n = 1), bilateral blurred vision (n = 1), bilateral hemianopsia (n = 1). Before starting treatment with TCZ, all patients had received high doses of prednisone, with a mean ± SD dose of 54.2 ± 13.8 mg / day (range of doses: 40-80 mg / day). In addition, 9 of them also received intravenous corticosteroid boluses. In addition, 13 patients received traditional immunosuppressants: methotrexate (MTX) (n= 12), cyclophosphamide (n = 2), leflunomide (n = 1) and azathioprine (n = 1). Regardless of corticosteroids, TCZ was administered as monotherapy in 14 patients, while in 6 it was administered in combination with MTX. The TABLE shows the evolution of the visual affectation of these patients. Throughout a median follow-up [RIC] of 9 [4-18] months, none of the 7 patients who had a blindness regained vision. The 2 patients who presented unilateral hemianopsia recovered vision. The patient with bilateral hemianopsia and the patient with bilateral blurred vision experienced a partial improvement. The remaining patients achieved a complete recovery.
Conclusion: Although TCZ seems to be also useful in the treatment of visual manifestations of ACG, once blindness is established, it does not seem to be effective.
