双盲,安慰剂控制的食物挑战 (DBPCFC) 和开放的食物挑战 (OpenFCs) 在儿童和成人中诊断花生过敏时显示出相似的结果. 严格的公开挑战标准是可靠诊断的关键.
科学领域:
- 过敏和免疫学 过敏和免疫学
- 临床诊断 临床诊断 临床诊断
背景情况:
- 双盲,安慰剂控制的食物挑战 (DBPCFC) 是诊断食物过敏的既定黄金标准.
- 在DBPCFC和开放式食品挑战 (OpenFCs) 之间进行的比较是有限的,特别是在症状严重程度和反应值方面.
研究的目的:
- 为了追溯比较儿童和成年人对花生过敏的症状严重程度和值,他们接受了OpenFC或DBPCFC治疗.
- 用严格的客观标准来评估OpenFC的可靠性.
主要方法:
- 通过口服食品挑战 (2001-2022) 诊断出花生过敏的患者的回顾性分析.
- 症状严重程度使用桑普森严重程度得分进行分级.
- 使用日志正常区间审查生存分析分析的值;评估安慰剂反应.
主要成果:
- 在OpenFC和DBPCFC之间没有发现症状严重程度或值的显著差异.
- 在DBPCFC期间,在儿童中观察到3级症状的更高发病率.
- 只有一个患者对安慰剂有积极反应.
结论:
- 在被训练有素人员严格客观的停止标准下进行OpenFC时,DBPCFC在诊断花生过敏方面并不明显优于OpenFC.
- 这些发现支持使用受良好控制的OpenFC作为可靠的诊断工具.

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...
Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
