| Outline of Final Research Achievements |
We compared the lung tissue of patients with acute exacerbations of interstitial pneumonia managed with VV ECMO with that of patients managed with ventilator alone, and found that the expression of various inflammatory and vascular endothelial markers was reduced in the group managed with VV ECMO, suggesting that management with VV ECMO may be useful in reducing lung damage. It was suggested that management with VV ECMO may be useful in controlling lung injury. Next, we examined changes in various markers using serum from patients who had actually been treated. In a study with a small number of patients, RAGE reflected the course of treatment the most. The analysis of the mechanism by which RAGE reflected the course of treatment in VV ECMO may provide a stepping stone to effective treatment of acute exacerbations of interstitial pneumonia.

| Academic Significance and Societal Importance of the Research Achievements |
RAGEが間質性肺炎の重症度や治療経過に何らかの関与している可能性が示唆された．VV ECMOを施行することでの効果なのか，その他の治療の効果などは現時点では不明である．さらなる症例集積を行い，メカニズムを解析することでRAGEのバイオマーカーとしての役割，ひいては重症間質性肺炎の治療へとつながる可能性がある．
