摘要 目的探讨白细胞介素-1受体拮抗剂(IL-1Ra)联合甲氨蝶呤(MTX)对中重度类风湿关节炎(RA)患者血清中趋化蛋白CCL5及RA活动度相关指标的影响,并对疗效进行初步评价。方法40例中重度RA患者随机双盲分为IL-1Ra+MTX组和安慰剂+MTX组,IL-1Ra80mg/d皮下注射qd×12周,MTX10mg/周一次口服×12周,并以20例健康体格者为正常对照,观察用药前后的血清CCL5浓度和RA活动度相关指标类风湿因子(RF)、C反应蛋白(CRP)、血沉(ESR)、关节肿胀个数、晨僵时间、关节触痛个数以及骨侵蚀度的变化,并用美国风湿学会评分(ACR)、健康问卷评估评分(HAQ)评价药物疗效。结果RA患者CCL5的浓度明显高于正常对照组。用药12周后,IL-1Ra+MTX组患者血清CCL5浓度低于安慰剂+MTX组,CCL5浓度与ESR、CRP、RF、关节肿胀个数、关节触痛个数、晨僵时间及骨侵蚀度均成正相关,P值均<0.05,IL-1Ra+MTX组与安慰剂+MTX组在用药12周后,ACR20分别为40%、25%,ACR50分别为20%、10%,ACR70分别为35%、5%(P<0.05);HAQ评分IL-1Ra+MTX组低于安慰剂+MTX组(P<0.001)。结论IL-1Ra+MTX组较安慰剂+MTX组可使血清中CCL5浓度下降更为明显。IL-1Ra联合MTX治疗类风湿关节炎较单用MTX治疗类风湿关节炎有着更好的ACR缓解率和病情改善。
