背景情况:
- 非典型喘,包括咳变异性喘 (CVA) 和胸部紧张变异性喘 (CTVA),在病理生理学方面受到的关注较少.
- 气道阻塞,特别是小气道阻塞,是喘发展的关键因素.
- 这项研究调查了非典型喘中小气道炎症 (SAI) 和小气道功能障碍 (SAD) 之间的联系.
研究的目的:
- 确定小气道炎症 (SAI) 是否导致非典型喘 (CVA和CTVA) 患者的小气道功能障碍 (SAD).
- 为了比较经典喘,CVA,CTVA和对照组的呼吸道炎症水平.
- 在不同类型的喘中识别与呼吸道炎症和功能障碍相关的危险因素.
主要方法:

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:

Asthma: Pathogenesis and Management
371
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.

Asthma-I: Introduction
2.6K
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
246
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...
