概括
喘患者的高免疫球蛋白E (IgE) 水平可以帮助在T2高和T2低喘中识别不同的临床表型. 这表明IgE是喘聚类的有用生物标志物,而不仅仅是用于预测T2高喘.
科学领域:
- * 肺部医学和过敏研究
- * 免疫学和喘表型化
背景情况:
- * 总血清免疫球蛋白E (IgE) 水平被认为是T2高喘的预测指标,并且在非过敏喘中被发现.
- *IgE在确定喘表型,特别是T2高的确切作用需要进一步研究.
研究的目的:
- * 评估将喘患者分成IgE高和IgE低组在已确定的T2高和T2低表型中分层的可靠性.
- * 探索与这些联合表型相关的临床,功能和生物幽默特征.
主要方法:
- *涉及大量喘患者的横截面单中心研究.
- *根据IgE水平 (≥100kU/L),过敏原敏感性,血中异氨基酸细胞数 (B-EOS ≥300/μL) 和部分呼出的氧化 (FENO ≥30ppb) 的分层.
主要成果:
- *确定了四种不同的表型:T2低-IgE低 (15.5%),T2低-IgE高 (5.1%),T2高-IgE低 (33.6%),和T2高-IgE高 (45.7%).
- * T2低-IgE低的患者表现出更多的心血管/代谢并发症和肺气.
- * T2低-IgE高的患者表现出更高的恶化率,鼻炎和焦虑/抑郁.
- * 在T2高范围内,低IgE与女性性别,肥胖和焦虑/抑郁相关.
结论:
- *T2Low喘患者的高IgE呈现出一种独特的表型,具有T2High类疾病严重程度和鼻并发症,同时保持T2Low特征.
- *血清IgE可作为额外的生物标志物用于T2-高和T2-低表型中的喘亚分群.
- *IgE被提议作为一个聚类生物标志物,而不是T2高喘的唯一预测因素.

Asthma-II: Pathophysiology and Classification
2.7K
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.

Asthma-I: Introduction
2.7K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
332
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...

Asthma: Pathogenesis and Management
439
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
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.
