Outline of Research at the Start

本研究の目的は、脳MRIの拡散強調画像で得られるapparent diffusion coefficient value (ADC値)とMRスペクトロスコピーで得られる脳内代謝物濃度の絶対値を、新生児の低酸素性虚血性脳症(HIE)の定量的な予後予測マーカーとして確立することである。新生児HIEの早期予後予測マーカーの確立は新生児HIEの適切な診療だけでなく新しい脳保護療法の開発にも寄与する。新生児HIEを対象にADC値と脳内代謝物濃度を新生児期に2回測定し、生後18ヶ月、3歳、6歳の発達予後の予後予測について検討し、幼児期早期だけでなく就学期の予後の予測マーカーとしての意義を明らかにする。

Outline of Final Research Achievements

This study aimed to measure the time course changes in biomarkers measured by MRI and MRS in neonatal hypoxic-ischemic encephalopathy (HIE) and to evaluate their prognostic value. Neonates with HIE admitted to our NICU between 2009 and 2018 were included in the study. Neurodevelopmental assessments were conducted at 18-22 months and 6 years of age, and the ADC values and brain metabolite concentrations were analyzed. Throughout the first two weeks, the concentration of NAA in the thalamus and basal ganglia was the most accurate predictor of prognosis. ADC values, lactate, and the lactate/NAA ratio were also useful predictors within 24-96 hours after birth, but during the first two weeks, only NAA retained a high predictive value, while the prognostic value of other biomarkers decreased. Data on the neurological prognosis at school age have been obtained from approximately 90 cases. Further analysis and reporting of these data are planned.

Academic Significance and Societal Importance of the Research Achievements

新生児低酸素性虚血性脳症は神経学的後遺症の主要な原因の一つである。MRIやMRSを用いた定量的で正確な予後予測マーカーとして広く利用可能になると、臨床と研究の両面で重要な利点がある。
臨床的には、治療やリハビリテーションの目標設定を家族と共有し、子どもと家族の将来の生活に関する客観的な情報を提供することが出来る。研究的には、神経保護治療の開発に貢献し、新生児HIEの神経学的発達予後の改善に寄与することが期待される。
