視神経脊髄炎では,プラズマブラストによるIL-6依存性の抗アクアポリン4抗体産生が病態に関与することに着目し,筆者らはヒト化抗IL-6受容体抗体トシリズマブによる治療の可能性を検証した。8症例に対する1年間の投与の結果では,年間再発回数,神経原性疼痛および疲労感の軽減が確認され,視神経脊髄炎におけるIL-6阻害療法は有望と考えられた。
Abstract
Our lab has previously shown that Interleukin (IL)-6- dependent production of autoantibodies against aquaporin 4 in plasmablasts may play a central role in the pathogenesis of neuromyelitis optica (NMO). In this study, we explored the efficacy of tocilizumab, a humanized antibody against IL-6 receptor, in intractable cases of NMO. Eight NMO patients who were unresponsive to current treatments received monthly injections of tocilizumab for at least one year. Tocilizumab significantly reduced the annual relapse rate, neurogenic pain, and fatigue in NMO patients. These results indicate that IL-6 signaling plays a crucial role in the pathogenesis of NMO and highlight the value of IL-6 receptor inhibition for the treatment of NMO.
