Objective: To evaluate effects of acitretin and methotrexate on treatment of severe plaque psoriasis.
Methods: A total of 54 patients were treated with either acitretin (32 patients; 30 mg per day) or methotrexate (22 patients; 15 mg per week) for 8 weeks. The therapeutic effects of the two drugs were evaluated according to the psoriasis area and severity index (PASI).
Results: After 8 weeks of treatment, the score of PASI decreased in both the acitretin group and the methotrexate group (P<0.001). However, there was no significant differences neither in the percentage reduction in the PASI score nor in PASI response rate between the two groups (P>0.05).
Conclusion: Acitretin and methotrexate exert similar therapeutic effect in severe plaque psoriasis.
目的：观察阿维A与氨甲蝶呤治疗重度斑块型银屑病的疗效。方法：54例确诊为斑块型银屑病的患者被分为阿维A组(32例，口服阿维A30 mg，每日1次)和氨甲蝶呤组(22例，口服氨甲蝶呤15 mg，每周1次)，均外用卡泊三醇软膏和硼酸软膏，疗程8周。以银屑病面积和严重度指数(psoriasis area and severity index，PASI)作为观察指标，比较两种药物的疗效。 结果：治疗后，阿维A组和氨甲蝶呤组PASI评分均较治疗前下降(P<0.001)，PASI评分改善率和PASI评分有效率在两组间比较差异均无统计学意义(均P>0.05)。结论：阿维A或氨甲蝶呤治疗重度斑块型银屑病均有效，且疗效相当。.
