多発性硬化症(MS)は、脳や脊髄を含む中枢神経系の慢性炎症を指します。多発性硬化症(MS)患者における嚥下障害の有無を評価することは、臨床現場での神経内科医の課題となっている。本研究の目的は、光ファイバー内視鏡検査に基づく Dysphagia Outcome Severity Score(DOSS)を用いて、患者が報告した尺度である DYMUS スコアと客観的症状との関係を検証することであった。データは多施設共同研究で収集されました。嚥下障害の有無にかかわらず、215人のMS患者が登録された。DOSSにより122例(56.7%)に嚥下障害が認められた。嚥下障害の有無は、非嚥下障害者と比較して、より重度の障害、疾患期間の長さ、および疾患の進行性と関連していた。DYMUSスコア0はDOSS6(感度100%)と強く相関し、2以上のDYMUSスコアは自己申告尺度のDOSS<7(特異度82%)と相関した。DYMUS問診票は、客観的な検査を受けて耳鼻咽喉科医に紹介すべき患者の赤旗を立てるための有用な臨床ツールとなります。
Multiple sclerosis (MS) refers to chronic inflammation of the central nervous system including the brain and spinal cord. Assessing for the presence of dysphagia in subjects with MS represents a challenge for neurologists in clinical practice. The aim of the present study was to verify the relationship between DYMUS scores, a patient-reported scale, and objective symptoms using the Dysphagia Outcome Severity Score (DOSS), based on fiber-optic endoscopy. Data were collected in a multicenter study. Two hundred and fifteen MS patients were enrolled, irrespective of self-reported dysphagia. DOSS revealed dysphagia in 122 subjects (56.7%). Compared with non-dysphagic subjects, the presence of dysphagia was related to more severe disability, longer disease duration, and a progressive form of the disease. A DYMUS score of 0 strongly correlated with a DOSS of 6 (sensitivity 100%) while DYMUS score of > 2 correlated with a DOSS < 7 (specificity 82%) of the self-reported scale. The DYMUS questionnaire can be a useful clinical tool for red-flagging patients who should undergo objective testing and referral to a otorhinolaryngologist.
