Ann Rheum Dis:类风湿性关节炎缓解后,以升高剂量策略持续停用英夫利昔单抗

2019-10-21 xiangting MedSci原创

程序化治疗策略并不能明显增加IFX停药1年后的持续缓解率。

这项研究目的是确定“程序化”英夫利昔单抗(IFX)治疗策略(根据基线血清肿瘤坏死因子αTNF-α)调整IFX剂量)是否有助于54周和IFX持续停药1年后临床缓解的诱导。

这项多中心随机试验中,对甲氨蝶呤反应不佳的IFX初治类风湿性关节炎患者被随机分为两组。程序治疗组在6周前接受3mg/kg IFX,在第14周后,根据基线血清TNF-α水平调整IFX剂量,直至第54周。标准治疗组的患者接受3mg/kgIFX。第54周简化疾病活动性指数(SDAI≤3.3的患者停用IFX。主要终点是第106周持续停用IFX的患者比例。

共有337例患者被随机分组​​。第54周时,程序治疗组的39.4%(67/170)和标准组的32.3%(54/167)患者达到缓解(SDAI≤3.3)。第106周时,两组间的1年持续停药率无明显差异,分别为程序治疗组23.5%(40/170)和标准组21.6%(36/167)(相差2.2%,95CI -6.6%至11.0%;p=0.631)。基线SDAI<26.0是第106周成功持续停用IFX的统计学显著预测指标。

程序化治疗策略并不能明显增加IFX停药1年后的持续缓解率。
