摘要:
目的:观察两种选择性环氧化酶(Cyclooxygenase,COX)-2抑制剂艾瑞昔布和塞来昔布对中轴型脊柱关节炎(AxialSpondyloarthritis,ax-SpA)患者的疗效和不良反应.方法:某院风湿免疫科就诊的ax-SpA患者180例,诊断符合2009年ASAS推荐的ax-SpA分类标准;分别随机给予艾瑞昔布0.1,0.2g或塞来昔布0.2g,每天2次,主要疗效指标为12周末患者背痛视觉模拟评分(Visual Analogue Scale,VAS)总体评分,次要疗效指标包括Schober试验、Bath强直性脊柱炎病情活动指数(Bath Ankylosing Spondylitis Disease Activity Index,BASDAI)、Bath强直性脊柱炎功能指数(Bath Ankylosing Spondylitis Functional Index,BASFI)、ESR、CRP的变化和不良反应.结果:最终完成12周随访者168例,其中艾瑞昔布0.2 g·d-1组55例,艾瑞昔布0.4 g·d-1组57例,塞来昔布组56例.12周时与基线期相比,艾瑞昔布组与塞来昔布组患者背痛VAS总体评分、Schober试验、BASDAI评分、ESR、CRP均较基线期改善有统计学意义(P<0.05),艾瑞昔布0.4 g·d-1和塞来昔布0.4g·d-1之间差异无统计学意义(P>0.05),患者背痛VAS总体评分、Schober试验、BASDAI评分优于艾瑞昔布0.2 g·d-1组.随访12周3组患者不良反应发生均轻微可控.结论:艾瑞昔布0.4 g·d-1和塞来昔布0.4 g·d-1在ax-SpA治疗中具有相似的疗效和不良反应,在症状控制和功能改善方面均优于艾瑞昔布0.2 g·d-1.%OBJECTIVE To demonstrate the clinical efficacy and safety of the selective cyclooxygenase (COX)-2 inhibitor imrecoxib compared with celecoxib in subjects with axial spondyloarthritis (ax-SpA).METHODS A total of 180 patients with ax-SpA in a hospital,diagnosed as per 2009 ASAS recommended ax-SpA classification standard,were randomly given imrecoxib 0.1,0.2 g or celecoxib 0.2 g,twice daily for 12 week.The primary efficacy endpoint was the change from baseline in global pain intensity on a visual analogue scale (VAS) at week 12.Secondary endpoints covered the Schober test,bath ankylosing spondylitis disease activity index (BASDAI),bath ankylosing spondylitis functional index (BASFI),ESR,CRP changes and adverse events.RESULTS A total of 168 patients finished the 12-week trial:imrecoxib 100 mg twice a day (n =55),imrecoxib 200 mg twice a day (n =57) and celecoxib 200 mg twice a day (n =56).The back pain VAS total score,Schober test,BASDAI score,BASFI score,ESR,CRP were improved significantly compared with baseline data in all imrecoxib groups and celecoxib groups (P<0.05).There was no difference between imrecoxib 0.4 g·d-1 and celecoxib 0.4 g·d-1 (P>0.05).Imrecoxib 0.2 g·d 1 group was all inferior in back pain VAS total score,Schober test,BASDAI score and BASFI score (P<0.05).The side effects were mild and controllable.CONCLUSION Celecoxib and imrecoxib 200 mg twice a day has similar efficacy and side effects against ax-SpA,and the combination is more effectively than imrecoxib 0.2 g· d-1 in symptom control and function improvement.Imrecoxib (either dose) and celecoxib are well tolerable.
