| Outline of Final Research Achievements |
Ventilator associated pneumonia (VAP) is an important cause of morbidity and mortality in hospitalized patients. The aim of our study was to investigate whether the innate immune response in the lung critical for the prognosis of VAP. A total of 134 VAP patients was collected, and we found that, late VAP (whose onset was more than 5 days after mechanical ventilation started), occurrence of Adult Respiratory Distress Syndrome(ARDS) in the course of VAP, and VAP caused by gram-negatives, as factors which worsen the prognosis of VAP. Those results suggest that the lung injury in the clinical course of VAP are likely caused by gram-negatives and progress to ARDS lead to poor prognosis. The lung epithelial cell-derived cytokines might be important to protect lungs during VAP.
