概括
组件解决诊断 (CRD) 和免疫标志物如sIgE,sIgG4和基激活测试 (BAT) 可以区分家尘虫 (HDM) -过敏鼻炎患者和无症状个体. 这些标志物还预测了接受皮下免疫疗法 (SCIT) 的儿童的治疗成功.
科学领域:
- 过敏原免疫疗法免疫疗法
- 临床免疫学 临床免疫学
- 儿科过敏症儿童过敏症
背景情况:
- 家庭灰尘虫 (HDM) 敏感化是过敏性鼻炎 (AR) 和喘的主要原因.
- 在接受皮下免疫疗法 (SCIT) 治疗HDM过敏的儿童中,组件解决诊断 (CRD) 和免疫标记的实用性尚未明确.
研究的目的:
- 使用特定的免疫球蛋白E (sIgE) 和sIgG4配置文件,区分HDM诱导的AR与无症状敏感化.
- 在症状儿童中SCIT后评估免疫标记的纵向变化.
- 探索这些标记物的潜力,作为SCIT成功的预测因素.
主要方法:
- 研究了72名对HDM敏感的参与者 (46名有症状的AR,26名无症状) 和8名健康对照.
- 32名有症状的患者接受了SCIT;40名没有.
- 在基线和18个月后测量了sIgE,sIgG4水平到HDM组件,以及基粒激活测试 (BAT);评估了临床结果 (C-ACT,VAS).
主要成果:
- 有症状的患者对Derp1,Derp2,Derf1和Derf2的sIgE升高.
- 对Derp2和Derf2的更高敏感性与AR和过敏喘相关.
- 在关键的HDM组件中,SCIT显著降低了sIgE,并增加了sIgG4,得到了BAT发现的支持;在非SCIT组中没有发生显著变化.
结论:
- CRD和BAT有效地区分了症状和无症状的HDM敏感性.
- 对sIgE,sIgG4和BAT的长度监测可能会改善SCIT的结果,并指导儿科患者的治疗决策.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
464
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Hypersensitivities
1.0K
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...

Allergic Drug Reactions
980
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...
