概括
免疫球蛋白E (IgE) 敏感性并不总是与持续的急性食物蛋白诱导肠球炎综合征 (FPIES) 相关. 虽然表型转换为IgE介导的食物过敏是罕见的,但FPIES中的IgE敏感性与临床结果没有明确的关系.
科学领域:
- 过敏和免疫学 过敏和免疫学
- 儿科胃肠病学 儿科胃肠病学
- 临床营养学 临床营养学
背景情况:
- 关于在急性食物蛋白诱导肠球炎综合征 (FPIES) 中免疫球蛋白E (IgE) 敏感化的证据有限.
- 最初的报道表明IgE敏感性和持续的FPIES之间存在联系,但最近的研究没有证实这种联系.
研究的目的:
- 在急性FPIES中,系统地审查IgE对罪祸首食物的敏感化和口服食物挑战的结果之间的关系.
- 评估被诊断患有急性FPIES的个体随着时间的推移对IgE介导食物过敏的敏感化,血清转化和表型转换率.
主要方法:
- 进行了系统审查,搜索了10个相关研究的数据库.
- 包括涉及儿童和成人被诊断患有急性FPIES的研究,通过皮肤刺伤或血清学测试评估IgE敏感性.
主要成果:
- 在1,830项已识别的研究中,有53项符合条件,包括3,514名参与者.
- 在急性FPIES中,整体敏感率为9.8%. 血清转化发生在1.1%的参与者中,并且在1.1%至13%的敏感个体中观察到表型切换到IgE介导的食物过敏.
- 十项研究分析了敏感化与疾病持续性之间的关联,其中4项发现了联系,6项没有发现.
结论:
- 没有找到一致的证据将IgE敏感性与FPIES持久性联系起来.
- 在急性FPIES中,表型转换为IgE介导的食物过敏并不常见.
- 在FPIES的背景下,IgE敏感性与临床结果没有明确的关系.

Hypersensitivities
495
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Asthma-II: Pathophysiology and Classification
2.6K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
