Biomolecules:类风湿性关节炎中是否会发生与安慰剂相关的不良事件?

2022-04-15 MedSci原创 MedSci原创

根据"对症下药"的倡议,类风湿性关节炎(RA)患者应迅速达到缓解或至少达到较低的疾病活动度,才能避免出现关节破坏,导致严重残疾和过早死亡。

根据"对症下药"的倡议,类风湿性关节炎(RA)患者应迅速达到缓解或至少达到较低的疾病活动度,才能避免出现关节破坏,导致严重残疾和过早死亡。来自前瞻性、双盲、随机、安慰剂对照的研究提供了最高质量的干预性证据。然而信息的缺失可能会导致对补充药物的不良事件估计不足。

在这项荟萃分析中,研究人员共总结了101项此类研究中安慰剂组的不良事件发生率,根据监管活动医学词典(MedDRA),纳入了安慰剂组的17150名患者和verum组的37819名患者。安慰剂治疗的患者中位数为55.0%、65.5%和72.5%(而verum组为72.3%),报告超过一次不良事件的比例为2.5%、5.8%和8.6%(而verum组为5.9%),分别以固定剂量的皮质类固醇、传统的合成改良病情的抗风湿药物(DMARDs)和生物DMARDs作为背景疗法。

不良事件方面,安慰剂和verum两组之间在恶心(1.00,95%置信区间(CI)为0.86-1.17)、肝胆疾病(1.08,CI为0.85-1.36)、肝功能异常(1.09,CI为0.83-1.44)以及一般疾病和用药部位情况(1.39,CI为0.95-2.03)方面的发生率相当。对于恶心(p=0.018;Egger检验)、腹泻(p=0.022)和严重感染和传染病(p=0.009),存在出版物偏差。

综上所述,患者应该意识到,即使使用安慰剂药物治疗,也可能会发生"不良事件",这与背景治疗中额外添加的verum药物治疗无关。需要进一步的研究来分析这些安慰剂相关的 "不良事件"背后的问题。
