title: Significance of measuring S100A12 and sRAGE in the serum of sepsis patients with postoperative acute lung injury.
abstract: BACKGROUND
  There is a report that S100A12 is useful as an early marker of acute lung injury (ALI). The purpose of this study was to determine whether S100A12 or sRAGE is useful as a marker during the development of ALI in postoperative sepsis patients.
  
  
  METHODS
  The subjects were patients who underwent emergency surgery because of sepsis secondary to perforation of the lower gastrointestinal tract. We conducted a retrospective study comparing 2 groups of patients: a group of 9 patients who developed postoperative ALI, the ALI(+) group, and a group of 8 patients who did not develop postoperative ALI, the ALI(-) group. Their blood S100A12, sRAGE, IFN-gamma, WBC count, and CRP values were measured immediately after surgery and on postoperative day 1 (D1).
  
  
  RESULTS
  The changes in S100A12 showed significantly higher values immediately postoperatively in the ALI(+) group (p < 0.05). The sRAGE values immediately postoperatively were similar, but on D1, they were significantly higher in the ALI(-) group (p < 0.05).
  
  
  CONCLUSIONS
  S100A12 increases in the early stage of development of ALI. sRAGE production increases in patients who do not develop ALI.
