title: [Change in serum intestinal fatty acid binding protein and its significance in children with pneumonia and gastrointestinal injury].
abstract: To study the change in serum intestinal fatty acid binding protein (IFABP) in children with pneumonia and its correlation with gastrointestinal injury.
  
  
  
  A total of 82 children with community-acquired pneumonia who were treated from January to October, 2015 were enrolled, among whom 34 had mild pneumonia and 48 had severe pneumonia. According to pediatric critical illness score (PCIS), the children with severe pneumonia were further divided into non-critical group (25 patients) and critical group (23 patients). Thirty healthy children who underwent physical examination at outpatient service were enrolled as the control group. ELISA was used to measure serum IFABP level, and the acute gastrointestinal injury (AGI) grade was determined for children with severe pneumonia. Serum IFABP level was compared between groups, and the correlations of IFABP with AGI grade and PCIS were analyzed.
  
  
  
  The severe pneumonia group showed a significantly higher serum IFABP level than the control group and the mild pneumonia group (P<0.01), and the mild pneumonia group also showed a significantly higher serum IFABP level than the control group (P<0.01). The critical group showed a significantly higher serum IFABP level than the non-critical group (P<0.01). The patients with grade I-IV AGI had significantly higher serum IFABP levels than the control group (P<0.01), and the serum IFABP level increased significantly with the increasing AGI grade (P<0.01). Serum IFABP level was positively correlated with AGI grade (P<0.01) but negatively correlated with PCIS (P<0.01).
  
  
  
  Children with pneumonia experience an increased serum IFABP level which can be used as a sensitive indicator for the early diagnosis of gastrointestinal injury and the evaluation of conditions in children with pneumonia.
