Research Abstract

髄液ヒスタミン値が過眠症状に依存性に低値であることが明らかになった。コントロ-ルに比べて、HLA-DR2陽性で脱力発作のあるオレキシンが低値のナルコレプシ-だけではなく、オレキシン値は正常である特発性過眠症、DR2 陰性や脱力発作のないナルコレプシ-でもヒスタミン値は有意に低値であった。しかしながら、リタリン等の中枢神経刺激薬を内服している症例では、対照群との有意差は認められなかった。ナルコレプシ-ではリタリンの内服の有無にて、オレキシン値に変化はないが、ヒスタミン値に関しては、高値になる傾向がみられた。ヒスタミン値は、睡眠時無呼吸症では対照群と同等な値であった。
