Lancet:湿疹婴儿鸡蛋过敏怎么办?

2016-12-09 xing.T MedSci原创

以逐步的方式接触加热的鸡蛋,联合积极的湿疹治疗是一种安全有效的方法以防止高危婴儿鸡蛋过敏。在这项研究中,研究者开发了一个实用的方法来克服食物过敏引起的第二波过敏性流行病。

越来越多的证据表明早期接触比被推迟接触作为一个更有益的策略来进行食物过敏一级预防。然而,对于固体食物的早期接触引起的过敏反应本身就是一个有问题。近日,顶级杂志Lancet上发表了一篇文章,研究人员探究早期逐步接触鸡蛋的湿疹婴儿结合最佳的湿疹治疗,在婴儿1岁时能否防止鸡蛋过敏。

在这项随机、双盲、安慰剂对照的试验中,研究人员招募了来自日本两个中心的4-5个月龄的湿疹婴儿。排除标准为37孕周前出生、摄入过鸡蛋或鸡蛋产品、鸡蛋引起的急性过敏反应病史、特殊类型的食物产生的非急性过敏性反应病史和任何严重疾病的并发症。婴儿被(1:1)随机分配来进行早期接触鸡蛋或安慰剂治疗。在鸡蛋组的参与者从6至9月龄每天食用50mg加热的鸡蛋粉,之后每天食用250mg,直到12月龄。研究者积极治疗受试者的湿疹,并保持参与者的湿疹在整个干预期间内没有恶化。对参与者和医生实施盲法使其无法知道分组情况。主要结局指标为在12月龄时通过标准化的方法评估食用鸡蛋过敏婴儿的比例,所有随机分配的参与者均接受干预。这项试验是在大学医院的医疗信息网络的临床试验注册中心进行了注册,编号为UMIN000008673。

从2012年9月18日至2015年2月13日之间,研究者随机分配了147名参与者(73名[50%]到鸡蛋组和74名[50%]到安慰剂组)。本试验是在100名参与者进行计划的中期分析结果的基础上而终止,这表明两组之间差异显著(鸡蛋组47名参与者中有4名[9%]发生鸡蛋过敏 vs. 而安慰剂组47名参与者中有18名[38%]发生鸡蛋过敏;风险比为0.222 [95%可信区间为0.081-0.607];P=0.0012)。在主要分析人群中,在鸡蛋组60名参与者中有5名(8%)参与者发生鸡蛋过敏,相比于安慰剂组61名参与者23名(38%)参与者发生鸡蛋过敏(风险比为0.221[0.090-0.543];P=0.0001)。两组之间的唯一有差异的不良事件是住院情况(在鸡蛋组60名参与者中有6名(10%),而安慰剂组每人住院,P=0.022)。在摄入试验粉末后,鸡蛋组9名(15%)参与者发生了19次急性事件,而对照组中11名(18%)参与者发生了14次急性事件。
