乙酸性喘 (EA) 和混合颗粒细胞性喘 (MGA) 是常见的. 血中乙氨基酸细胞有效地识别EA,指导喘治疗. 生物标志物对于个性化喘治疗至关重要.
科学领域:
- 肺部病理学 肺部病理学
- 免疫学 免疫学 免疫学
- 生物化学 生物化学
背景情况:
- 诱导的唾液在常规喘表型化中未得到充分利用.
- 识别炎症性喘表型是针对性治疗的关键.
- 生物标志物可以区分喘亚型并指导治疗.
研究的目的:
- 使用诱导液来确定炎症性喘表型的患病率.
- 识别生物标志物以区分这些表型.
- 评估生物标志物在有或没有生物治疗的患者中的效用.
主要方法:
- 80名喘患者的横截面研究.
- 评估了临床数据,喘控制,皮肤刺伤测试,脉冲振荡计,螺旋计,诱导和各种生物标志物 (IgE,乙酸蛋白,FeNO,环素,IL-5,IL-6,IL-8,IL-17A,IL-33).
- 包括17名接受生物疗法 (奥马利祖马布或本拉利祖马布) 的患者.
主要成果:
- 酸性喘 (EA) 和混合颗粒细胞性喘 (MGA) 是最常见的 (31%和30%).
- 血中乙氨基酸细胞计数 (≥240/μL) 确定EA具有64%的灵敏度和72.7%的特异性.
- 升高的IL-8与中性友性喘 (NA) 相关;较高的IL-17A与没有生物药物的EA相关.
- 生物治疗的EA显示较高的IL-5;生物治疗的MGA显示较高的IL-5,IL-6和IL-8.
结论:
- EA和MGA是主要的喘炎症表型.
- 血中乙氨基酸细胞计数是识别EA的可靠生物标志物,无论生物用途如何.
- 除了临床资料之外,一个全面的生物标志物小组对于最佳的喘管理至关重要.

Asthma-II: Pathophysiology and Classification
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:
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Asthma-I: Introduction
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
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...
