Ann Rheum Dis:COBRA早期类风湿性关节炎试验队列随访23年后的正常死亡率

2019-03-01 xiangting MedSci原创

研究证实RA的早期强化治疗具有长期获益,并提示靶向治疗对预后不良的患者尤为重要。

类风湿性关节炎(RA)患者的死亡率高于一般人群。这项研究调查了COBRA试验队列23年随访后的死亡率,并与荷兰人群的参考样本进行比较。

COBRA试验将早期RA患者随机分为柳氮磺吡啶单药治疗组(SSZ,n=79)或SSZ、低剂量甲氨蝶呤联合用药组,联合用药组最初予高剂量泼尼松龙,并逐步减量(COBRA,n=76)。将COBRA试验截至2017年的死亡率与荷兰一般人群参考样本进行比较(标准化死亡率,SMR)并通过逐步Cox回归分析了其与早期预后因素的关系。

幸存患者的平均随访时间为23年(范围22-24)。总的来说,有44名患者死亡(28%,SMR=0.80 [95%CI 0.59-1.06]);75名COBRA患者中有20名死亡(27%,SMR 0.75 [0.47-1.14]),79名SSZ患者中有24名死亡(30%,SMR 0.85 [0.56-1.25]); p=0.61)。一般人群的参考样本中,55人死亡(36%)。5个因素与死亡率危险升高显著相关:28周的损伤进展;健康评估问卷(HAQ)评分高和缺乏HLA-DR 2或3;从主诉开始的病程也与死亡率危险升高显著相关,但表现为一种无法解释的类型。

这项早期RA的前瞻性试验队列研究是首个显示RA患者随访23年后的死亡率与一般人群相似的研究之一。它证实RA的早期强化治疗具有长期获益,并提示靶向治疗对预后不良的患者尤为重要。
