Outline of Research at the Start

「橋本脳症」は、慢性甲状腺炎に伴う自己免疫性精神神経疾患で、免疫治療が奏効する。橋本脳症の中には幻覚・妄想を呈する患者も多く、統合失調症の中に橋本脳症が潜在する可能性がある。本研究では、①抗NAE抗体を用いて統合失調症と診断されている患者から橋本脳症を抽出し、②その臨床的特徴(臨床情報・症候、脳画像MRI、脳還流SPECT)と背景遺伝子多型(免疫関連)を明らかにし、最終的に③診断指針を作成する。

Outline of Final Research Achievements

We examined the clinical features in 2,350 cases in which anti-NAE autoantibodies were analyzed in our laboratory from 2016 to 2021. We screened 32 cases of Hashimoto encephalopathy (HE) and detected 8 cases of positive for anti-NAE autoantibodies. In 9 cases, steroid were administrated and effective 3 out of 7 cases. We also analyzed anti-NAE antibodies in patients who were diagnosed as having schizophrenia, and detected 10 out of 20 cases for positive. These findings strongly sugge4sted the possibility of latent patients with HE in schizophrenia.

Academic Significance and Societal Importance of the Research Achievements

統合失調症の一部に自己免疫が背景にありステロイドを含め免疫療法が効果のある橋本脳症が存在することは、根治療法の可能性があり、抗精神病薬に抵抗性の患者の治療にも寄与する。患者のQOLの向上や社会復帰にもつながり、患者・家族にとって大きな福音となる。
