Outline of Final Research Achievements

Excessive immulogical reaction, including neutrophil extracelluar traps (NETS) were suggested to involved in the pathogenesis of severe infectious diseases, such as influenza and its related pneumonia. We could focused on theses pethophysiology, especially on neutropfil reactions, and reported the successful treated cases by immunomodulative drugs, such as streoid and macrolides.

Academic Significance and Societal Importance of the Research Achievements

重症化が進んだインフルエンザ肺炎や新型コロナウイルス感染症などでは救命が困難となるため、早期発見からの早期治療の導入、普段からの感染制御・耐性菌や耐性ウイルス予防が重要となる。この点で、近年多くの臨床現場で原因菌同定に使用されている質量分析器(TOF-MS)の重複感染症例での問題点や迅速解析法、抗菌薬適正使用支援(AST)活動の成果としての緑膿菌の抗菌薬感受性の回復、MRSAに対するバンコマイシンのより至適な投与設計法などを報告できた。
さらに、インフルエンザのアウトブレイクに伴う抗インフルエンザ薬の予防投与の実態を検証し、介入以前と介入後での医学的、そして医療経済的な適正使用を確認できた。
