Outline of Final Research Achievements

Septic shock is one of diseases whose pathogenesis is to be elucidated in spite of recent progress in critical care medicine. The aim of this study is to analyze BH4 and its related-metabolites during sepsis and reveal its pathophysiology. The values of BH4 and related-metabolites changed out of normal levels early from the onset of infection, suggesting these changes are related with NO production and clinical course. Also we administered AsA against septic model mice to prevent further oxidation and gained the result of better survival.

Academic Significance and Societal Importance of the Research Achievements

本研究による成果は、未だ死亡率の高い敗血症性ショックの病態メカニズムの解明につながる。病態メカニズムが解明されることで、これまでは対症療法が主体であった敗血症に対する臨床診療においても、BH4とその関連代謝物を指標とした新しい治療法の確立が期待でき、これによって死亡率の低下を実現できる可能性がある。
