Session Time: 9:00AM-11:00AM
Background/Purpose: To assess the efficacy of Tocilizumab (TCZ) in refractory thyroid associated orbitopathy (TAO) due to Grave’s disease.
Methods: Multicenter study of 46 patients with TAO refractory to conventional immunosuppressive therapy.
Results: We studied 46 patients (85 eyes) (37 women/9 men); mean age at diagnosis 49.2±11.8 years. Besides oral corticosteroids and before the onset of TCZ, patients had been treated with pulses of intravenous methylprednisolone (n=42), radioactive iodine (n=4), methotrexate (n=2) and other drugs (methimazole in 8 cases, leflunomide in 1, azathioprine in 1, selenium in 11). Urgent decompressive surgery had to be performed in 7 patients. According to the classification of severity of the EUGOGO group (European Group on Graves’ Orbitopathy) using the clinical activity score (CAS), before TCZ onset patients whose data were available had severe (n=27 eyes) or moderate (n=34 eyes) disease. Moreover, patients presented exophthalmos (n=53 eyes), strabismus (n=37 eyes), muscle fibrosis (n=38 eyes) and dysthyroid optic neuropathy (n=10 eyes). TCZ was used in monotherapy (n=43) or combined with methotrexate (n=2) or azathioprine (n=1) at 8 mg/kg/iv/4 weeks (n=41) or 162 mg/sc/week (n=5). TCZ yielded rapid and maintained improvement in all ocular parameters as shown in Table 1. After a mean of 7.42±6.41 months using TCZ and a mean follow-up of 16.47±11.99 months, all patients experienced ocular improvement, with TCZ withdrawal in 28 cases due to complete remission (n=10), improvement (n=12) or stability of ocular inflammation (n=3), inefficacy (n=2) and total thyroidectomy (n=1). Only 5 relevant adverse effects were observed (neutropenia, external otitis, otitis media, costal osteitis and gingival hyperplasia, 1 each).
Conclusion: TCZ appears to be useful in TAO treatment.
