title: [Prognostic values of Th17 cells level in bronchoalveolar lavage fluid in children of sepsis with acute lung injury].
abstract: OBJECTIVE
  To observe the changes in Th17 cell levels in bronchoalveolar lavage fluid in children of sepsis with acute lung injury and the relationship between the Th17 cell levels and prognosis.
  
  
  METHODS
  Fifty children of sepsis with acute lung injury were enrolled in the study. The percentages of Th17 cells in bronchoalveolar lavage fluid were measured by flow cytometry. The patients of sepsis with acute lung injury were classified into three groups based on the Pediatric Critical Illness Score (PCIS): extremely critical, critical and non-critical. According to the clinical prognosis, the patients were classified into survical and death groups. Th17 cell levels were compared between the two groups. The relationship between Th17 cell levels and the PCIS scores was analyzed.
  
  
  RESULTS
  With the increase in the severity of sepsis, Th17 cell levels in bronchoalveolar lavage fluid were gradually increased (P<0.05). The Th17 cell levels were negatively correlated to the PCIS scores (r=-0.853; P<0.01). The Th17 cell levels were significantly higher in the death group than in the survival group. Moreover, compared with the survival group, the PCIS scores were lower in the death group (P<0.05).
  
  
  CONCLUSIONS
  The increased Th17 cell levels in children of sepsis with acute lung injury are closely related to the severity and prognosis of patients, suggesting that Th17 cell levels can be used as a predictor of the severity and prognosis.
