背景情况:
- 在喘中常见的气道过敏反应 (AHR) 在慢性阻塞性肺病 (COPD) 中未得到充分承认.
- 越来越多地认识到COPD异质性,包括eosinophilic COPD和喘-COPD重叠,突出了AHR作为2型 (T2) 炎症的标志物.
- 这种T2高的表型影响了20-40%的COPD患者,引发了针对IL-4,IL-5,IL-13和TSLP的生物药物的兴趣.
研究的目的:
- 审查目前关于COPD中AHR的证据.
- 探索AHR,炎症表型,诊断方法和COPD治疗影响之间的关系.
- 评估AHR作为COPD管理中的潜在可治疗特征.
主要方法:
- 对COPD中AHR现有文献的审查.
- 诊断方式的分析:直接挑战 (例如,甲醇) 评估呼吸道几何学与间接挑战 (例如,曼尼托尔) 反映T2炎症.
- AHR与炎症标志物的相关性,如乙氨基基细胞和部分呼出的氧化 (FeNO).
主要成果:
- 在COPD中,AHR涉及结构和炎症机制.
- 间接挑战比直接挑战更好地与T2炎症标志物 (乙素,FeNO) 相关联.
- 患有AHR的患者可能对吸入性皮质类固醇有更好的反应;生物药物显示有前途,但需要特定的COPD试验.
结论:
- AHR是COPD的临床相关特征,特别是在T2高的表型中.

Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

4.1K
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.

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

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.

3.5K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
