BACKGROUND The oral food challenge (OFC) in IgE mediated food allergy causes anxiety both in parents and in patients due to its inherent risks. OBJECTIVE Documentation of the rate, spectrum, and predictors of positive reactions is instructive. METHODS Children, who underwent OFC between January 1, 2017 and December 31, 2019 were analyzed. RESULTS A total of 1361 OFCs in 613 cases were reviewed. Most of them were performed in preschool children (≤2 years 50%) and 55% of them had more than one OFC. Mainly considered food groups were cow's milk (31.8%), hen's egg (28.5%), tree nuts (20%), legumes (7%), seeds (4.9%), and wheat (2.7%). The overall OFC positivity was 9.6%, whereas 6.7% with cow's milk, 4.9% with hen's egg, 16.1% with tree nuts, 21.6% with wheat, and 32.8% with seeds. The severity scoring revealed grade I (24.4%), II (45.8%), and III (29.7%) reactions. Fifty (38%) cases required epinephrine and four cases required hospitalization. OFCs with sesame seeds (odds ratio [OR]: 7.747, [confidence interval (CI) 95%: 4.03-14.90]), wheat (OR: 3.80, [CI: 1.64-8.84]), and tree nuts (OR: 2.78, [CI: 1.83-4.23]) predicted a positive OFC while a concomitant asthma (OR: 3.61 [CI: 1.27-10.28]) was more likely to elicit anaphylaxis. CONCLUSION In OFC practice, priority is given to basic nutritional sources and the most frequent food allergens, where preschool children with multiple sensitizations are the primary subjects. Increased risks of positive reactions with sesame, tree nut, and wheat and increased risk of anaphylaxis with concomitant asthma should be considered while performing OFC.

地中海东部儿童在IgE介导的食物过敏中口服食物挑战。

背景技术IgE介导的食物过敏中的口服食物挑战(OFC)由于其固有的风险而在父母和患者中引起焦虑。目的积极反应的发生率,频谱和预测因子的文献具有指导意义。方法对2017年1月1日至2019年12月31日接受OFC的儿童进行分析。结果共对613例OFC进行了检查。其中大多数是在学龄前儿童(≤2岁,占50%)中进行的,其中55%有一个以上的OFC。主要考虑的食物类别为牛奶(31.8%),鸡蛋(28.5%),坚果(20%),豆类(7%),种子(4.9%)和小麦(2.7%)。总体OFC阳性率为9.6%,而牛奶为6.7%,鸡蛋为4.9%,坚果为16.1%,小麦为21.6%,种子为32.8%。严重程度评分显示为I级(24.4%),II(45.8%)和III(29.7%)反应。五十例(38%)需要肾上腺素,四例需要住院。具有芝麻种子的OFC(赔率[OR]:7.747,[置信区间(CI)95%:4.03-14.90]),小麦(OR:3.80,[CI:1.64-8.84])和坚果(OR:2.78) ,[CI:1.83-4.23])预测OFC阳性,而伴随哮喘(OR:3.61 [CI:1.27-10.28])更容易引起过敏反应。结论在OFC实践中,优先考虑基本营养来源和最常见的食物过敏原,其中以多种敏化作用的学龄前儿童是主要对象。进行OFC时,应考虑增加与芝麻,坚果和小麦发生积极反应的风险,以及伴随哮喘发生过敏反应的风险增加。五十例(38%)需要肾上腺素,四例需要住院。具有芝麻种子的OFC(赔率[OR]:7.747,[置信区间(CI)95%:4.03-14.90]),小麦(OR:3.80,[CI:1.64-8.84])和坚果(OR:2.78) ,[CI:1.83-4.23])预测OFC阳性,而伴随哮喘(OR:3.61 [CI:1.27-10.28])更容易引起过敏反应。结论在OFC实践中,优先考虑基本营养来源和最常见的食物过敏原,其中以多种敏化作用的学龄前儿童是主要对象。进行OFC时,应考虑增加与芝麻,坚果和小麦发生积极反应的风险,以及伴随哮喘发生过敏反应的风险增加。五十例(38%)需要肾上腺素,四例需要住院。具有芝麻种子的OFC(赔率[OR]:7.747,[置信区间(CI)95%:4.03-14.90]),小麦(OR:3.80,[CI:1.64-8.84])和坚果(OR:2.78) ,[CI:1.83-4.23])预测OFC阳性,而伴随哮喘(OR:3.61 [CI:1.27-10.28])更容易引起过敏反应。结论在OFC实践中,优先考虑基本营养来源和最常见的食物过敏原,其中以多种敏化作用的学龄前儿童是主要对象。进行OFC时,应考虑增加与芝麻,坚果和小麦发生积极反应的风险,以及伴随哮喘发生过敏反应的风险增加。小麦(OR:3.80,[CI:1.64-8.84])和坚果(OR:2.78,[CI:1.83-4.23])预测OFC阳性,而伴发哮喘(OR:3.61 [CI:1.27-10.28] )更有可能引起过敏反应。结论在OFC实践中,优先考虑基本营养来源和最常见的食物过敏原,其中以多种敏化作用的学龄前儿童是主要对象。进行OFC时,应考虑增加与芝麻,坚果和小麦发生积极反应的风险,以及伴随哮喘发生过敏反应的风险增加。小麦(OR:3.80,[CI:1.64-8.84])和坚果(OR:2.78,[CI:1.83-4.23])预测OFC阳性,而伴发哮喘(OR:3.61 [CI:1.27-10.28] )更有可能引起过敏反应。结论在OFC实践中,优先考虑基本营养来源和最常见的食物过敏原,其中以多种敏化作用的学龄前儿童是主要对象。进行OFC时,应考虑增加与芝麻,坚果和小麦发生积极反应的风险,以及伴随哮喘发生过敏反应的风险增加。优先考虑基本营养来源和最常见的食物过敏原,其中具有多种敏化作用的学龄前儿童是主要对象。进行OFC时,应考虑增加与芝麻,坚果和小麦发生积极反应的风险,以及伴随哮喘发生过敏反应的风险增加。优先考虑基本营养来源和最常见的食物过敏原,其中具有多种敏化作用的学龄前儿童是主要对象。进行OFC时,应考虑增加与芝麻,坚果和小麦发生积极反应的风险,以及伴随哮喘发生过敏反应的风险增加。
