Background/Purpose: Non ischaemic optic neuritis (NION) is a severe inflammation of the optic nerve that may lead to blindness. It can be primary or associated to immune mediated inflammatory diseases (IMIDs). The treatment of the NION is based on systemic corticosteroids and conventional immunosuppressive drugs. Our aim was to assess the efficacy of the biological treatment in refractory NION to conventional treatment.
Methods: Multicenter study of 12 patients diagnosed with NION refractory to systemic corticosteroids and at least one conventional immunosuppressive drug. The main outcomes were visual acuity (VA) and optical coherence tomography (OCT) of the optic nerve and the ganglionar cells. Comparisons were made between baseline and the 1st week, 1st and 6th month and 1st year. (STATISTICA, StatSoft Inc. Tulsa, Oklahoma, USA).
Results: We studied 12 patients (19 affected eyes) (5 men/ 7 women); mean age of 29.8 ±12.9 years. The underlying diseases were systemic lupus erythematosus (n=1), neuromyelitis optica (n=1), neuroretinitis (n=1), relapsing polychondritis (n=1), pars planitis (n=1), Behçet´s disease (n=2) and idiopathic (n=5). Before biological treatment and besides oral corticosteroids, patients had received intravenous (IV) methylprednisolone boluses (n=9), cyclosporine A (n=1), cyclophosphamide (n=2), mycophenolate (n=2), hydroxychloroquine (n=1), methotrexate (n=8) and azathioprine (n=5). Biological treatment was bases on rituximab (n=2) (2 IV, doses of 1 g/every 2 weeks and every 6 moths), adalimumab (n=5) (40 mg/1-2 week), tocilizumab (n=4) (8 mg/kg/2-4 weeks) and infliximab (n=3) (5 mg /kg at 0, 2 and 6 week and then every 8 weeks). The characteristics of the 12 patients are shown in the TABLE.
After biological treatment we observed an improvement in the ocular parameters: VA [0.66±0.32 to 0.84±0.29; p= 0.03], OCT of the optic nerve [123.20±58.28 to 190.54±175.38; p= 0.11], and OCT of the ganglionar cells [369.55±137.37 to 270.67±23.21; p= 0.03] at one year. After a mean follow-up of 29.09 ±19.23 months, there were no severe adverse effects.
Conclusion: Biologic therapy in NION idiopathic or associated to IMIDs, refractory to conventional treatment, seems to be effective.
