概括
常年过敏性鼻炎患者的虫过敏通常表明对其他关节动物的更广泛的敏感性. 这种交叉反应性影响风险评估和个性化过敏治疗策略.
科学领域:
- 过敏和免疫学 过敏和免疫学
- 环境健康 环境健康
背景情况:
- 虫过敏是过敏反应的普遍触发因素,可能与与其他过敏原交叉反应有关.
- 长期过敏性鼻炎 (PAR) 患者经常表现出复杂的敏感化模式.
研究的目的:
- 调查已证实对虫过敏的PAR患者对关节动物过敏原的敏感化模式.
- 评估虫过敏原与其他环境或食品过敏原之间的交叉反应程度.
主要方法:
- 对 (Blattella germanica) 和其他常见的吸入过敏原进行了皮肤刺伤测试 (SPT).
- 使用ALEX2多重检测法检测了过敏原和交叉反应分子的特定IgE.
- 有48名PAR患者参与了该试验,其中46人接受了ALEX2测试.
主要成果:
- 在48名患者中,只有2名患者对特定的过敏原IgE水平升高 (Bla g 1, Bla g 4).
- 有相当数量的患者表现出对交叉反应性过敏原的敏感性,这些过敏原经常与其他节肢动物有关.
- 在过敏和对食用昆虫,海鲜,和某些黄蜂物种的敏感性之间发现了相关性.
结论:
- 在PAR患者中对的敏感性与更广泛的交叉反应性过敏原相关.
- 这些发现提高了对过敏原交叉反应性的理解,为个性化风险评估和过敏性鼻炎的治疗提供了信息.
- 对交叉过敏性的进一步研究可以指导向免疫疗法和避免过敏原的策略.

Drug Toxicity: Allergic Reactions
85
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Allergic Reactions: Anaphylaxis
103
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin,...
