背景:
川崎病患者经皮质类固醇强化治疗后仍可发生冠状动脉异常。我们的目的是确定在PostRAISE(免疫球蛋白加类固醇治疗川崎病分层治疗的前瞻性观察研究)中CAA发展的危险因素和对强化治疗的耐药性,这是迄今为止最大的川崎病患者的前瞻性队列。
方法:
在RAISE后,连续入选了例川崎病患者。本研究分析了例预计为静脉免疫球蛋白(IVIG)无反应者(Kobayashi评分≥5),接受了IVIG联合泼尼松龙的强化治疗。在发病后1个月检查基线特征和CAA之间的关联。还研究了基线特征与治疗耐药性之间的关系。
结果:
在基线≥2.5时最高Z评分(比率,3.4[95%CI,1.5-7.8]),发烧年龄1年(几率,3.4[95%CI,1.6-7.4]),无反应IVIG加泼尼松龙的治疗(优势比为6.8[95%CI,3.3-14.0])是CAA发展的独立预测因子。对IVIG加泼尼松龙的无反应性与8个基线变量显著相关。基线总胆红素(比值比为1.4[95%CI,1.2-1.7])是唯一有效的独立预测因子,而不是Kobayashi评分中包含的变量,从而可以在诊断时确定治疗耐药性。ROC曲线下的面积为0.74(95%CI,0.69-0.79)。在1.0的临界点,预测治疗耐药性的敏感性和特异性分别为71%和65%。
结论:
在RAISE后,发烧时年龄更小,基线时Z值最大,对IVIG和泼尼松龙的无反应性是与CAA发展密切相关的危险因素。在诊断时,可以根据总胆红素值确定是否为无反应者。为预防CAA,对于具有这些危险因素的患者,应考虑使用其他药物,进行更强化或辅助的治疗,如甲基强的松龙,环孢素,英夫利昔单抗和阿那白滞素。
