ARD:通过对青少年特发性关节炎的治疗退出进行风险适应分层来预防疾病发作:PREVENT-JIA 试验的结果

2022-07-08 MedSci原创 MedSci原创

S100A12/高敏C反应蛋白作为亚临床炎症的标志物可能有助于评估发作风险并指导治疗决策。使用亚临床炎症的预测标志物是治疗退出决策过程中的一个有前途的工具。

目的在幼年特发性关节炎临床缓解中停止治疗的决策仍然具有挑战性。研究高敏C反应蛋白(hsCRP)S100A12作为临床缓解幼年特发性关节炎(JIA)儿童成功停药的预测生物标志物的能力。

方法这项多中心试验(PREVENT-JIA)招募了119名处于临床缓解期的JIA患者,其中100名患者进入干预阶段,根据S100A12hsCRP水平决定是否继续或停止治疗。停止药物治疗后,对患者进行为期12个月的监测,以防止疾病发作。将结果与来自德国 Biologika in der Kinderrheumatologie (BiKeR)药物警戒登记的患者在没有基于生物标志物的分层的情况下停止治疗进行了比较。

结果PREVENT-JIA组中,49名患者出现发作,45%的停药患者在接下来的12个月内出现发作。所有患者(n = 8)由于不止一次就诊时S100A12/hsCRP永久升高而在观察阶段突然发作。在BiKeR对照组中,总发作率为62%,停药后发作率为60%主要结果,即从停药到第一次发作的时间(停药后的累积发作率)显示出有利于PREVENT-JIA组的显著差异(p=0.046HR 0.6295%CI 0.38-0.99S100A12/高敏C反应蛋白作为亚临床炎症的标志物可能有助于评估发作风险并指导治疗决策。作为另一个发现,PREVENT-JIA试验中的患者明显更早地停止了治疗。

结论生物标志物指导的治疗退出策略在临床实践中是可行的。这项研究表明,使用亚临床炎症的预测标志物是治疗退出决策过程中的一个有前途的工具,这可以转化为患者的直接利益。
