Outline of Final Research Achievements

This study focused on cell-free miRNAs to compare miRNA expression in the search for a minimally invasive biomarker to distinguish seizure disorder from acute encephalopathy in the early stage of disease onset. We compared the expression of 148 miRNAs by real-time PCR quantitative analysis and comparative Ct method using Pathway-focused miRNA PCR Array in serum from 10 cases of acute encephalitis with refractory, repetitive partial seizures: AERRPS and 10 cases of pediatric epilepsy. miR-124-3p, miR-372-3p and miR-145-5p were significantly up-regulated in the AERRPS group, while miR-215-5p was significantly down-regulated, suggesting that miRNAs may be as biomarkers to distinguish between the two groups.

Academic Significance and Societal Importance of the Research Achievements

小児急性脳症は希少疾患であるが死亡に至る難病である。早期の診断・治療介入が望ましいが、発症時は熱性けいれんなどのけいれん性疾患との鑑別が困難で確定診断に数日を要する。臨床現場では急性脳症とけいれん性疾患を早期に区別する高感度で簡便な診断バイオマーカーが求められている。本検討では小児急性脳炎脳症の亜群である難治頻回部分発作重積型急性脳炎においてけいれん性疾患と区別する有用な診断バイオマーカー候補が同定された。今後は本研究成果をもとに小児急性脳炎脳症の低侵襲性かつ早期診断として有用なバイオマーカーとして臨床応用へ発展させる一助になる可能性がある。
