title: [Changes in interleukin-1beta in serum and bronchoalveolar lavage fluid in the patient with acute respiratory distress syndrome].
abstract: OBJECTIVE
  To study the role of interleukin-1beta (IL-1beta) in the pathogenesis of acute respiratory distress syndrome (ARDS).
  
  
  METHODS
  The bronchoalveolar lavage fluid (BALF) and serum in 13 patients with ARDS and 9 healthy controls were collected. The contents of IL-1beta were measured by enzyme-linked immunoadsorbent assay(ELISA).
  
  
  RESULTS
  The levels of IL-1beta in BALF [(144.67+/-80.79)ng/L] and serum [(45.71+/-7.09)ng/L] in patients with ARDS were significantly higher than those in the control groups [(20.39+/-1.87)ng/L, P=0.000; (35.06+/-5.46)ng/L, P=0.001, respectively], and the levels of IL-1beta in BALF were also significantly higher than those of the serum in the patients with ARDS (P=0.000).
  
  
  CONCLUSIONS
  The results indicate that IL-1beta is involved in the pathogenesis of ARDS. Early determination of IL-1beta level in BALF may be more valuable in the evaluation of disease process of ARDS.
