title: Intercellular adhesion molecule-1 expression in nasal polyps treated with corticosteroid.
abstract: OBJECTIVE
  The aim of this study was to compare intracellular adhesion molecule-1 (ICAM-1) expression in nasal polyp cases who were administered topical corticosteroid and in middle turbinates.
  
  
  METHODS
  Twenty-four patients with nasal polyps were included in the study group. These patients were treated with 100 microg budesonide in each nostril twice daily for 2 months before the surgery. Twenty-one nonatopic patients with concha bullosa were included in the control group. The specimens were taken from patients undergoing endoscopic surgery.
  
  
  RESULTS
  In polyps, significantly higher mean ICAM-1 intensity scores were found by comparison with the control turbinates.
  
  
  CONCLUSIONS
  Corticosteroid treatment in patients with nasal polyps does not diminish ICAM-1 to that of turbinate tissue. The initiating events in the formation of nasal polyps still occur in these patients despite treatment with the topical nasal steroid.
