title: Efficacy of celecoxib, a cyclooxygenase 2-specific inhibitor, in the treatment of ankylosing spondylitis: a six-week controlled study with comparison against placebo and against a conventional nonsteroidal antiinflammatory drug.
abstract: OBJECTIVE
  To evaluate the short-term efficacy of celecoxib, a cyclooxygenase 2-specific inhibitor, in the treatment of ankylosing spondylitis (AS).
  
  
  METHODS
  The study was a 6-week randomized, double-blind, placebo-controlled trial with 3 treatment arms: placebo, ketoprofen 100 mg twice daily, and celecoxib 100 mg twice daily. Patients who had AS according to the modified New York criteria, without peripheral synovitis and with active disease (pain > or =40 mm on a 100-mm visual analog scale [VAS] and an increase in pain of at least 30% after nonsteroidal antiinflammatory drug withdrawal) were eligible for study. Primary outcome measures were change in pain intensity (VAS) and change in functional impairment (Bath Ankylosing Spondylitis Functional Index [BASFI]).
  
  
  RESULTS
  Of the 246 randomized patients, 76 were allocated to receive placebo, 90 ketoprofen, and 80 celecoxib. There were no statistically significant differences between treatment groups at study entry. During the 6 weeks of the study, the decrease in pain and functional impairment was greater in the active treatment groups than in the placebo group, with a trend in favor of celecoxib when the 2 active treatments were compared. The mean changes were -13 mm, -21 mm, and -27 mm (P = 0.006) for pain and 1, -6, and -12 (P = 0.0008) for BASFI score in the placebo, ketoprofen, and celecoxib groups, respectively. During treatment, the number of patients reporting epigastric pain was 6 (8%), 13 (14%), and 10 (13%) in the placebo, ketoprofen, and celecoxib groups, respectively.
  
  
  CONCLUSIONS
  The results of this study confirm the clinically relevant antiinflammatory effect of celecoxib at a 200-mg daily dosage, with significant improvement of both pain and function in patients with AS.
