- 呼吸系统医学 呼吸系统医学
- 临床免疫学临床免疫学
背景情况:
- 血中乙氨基酸细胞数量升高与COPD恶化风险有关.
- 在最佳治疗的稳定性COPD患者中,乙氨基基和恶化之间的关联仍然不清楚.
研究的目的:
- 为了研究血液中乙氨基细胞数量的增加和在接受双重支气管扩展剂治疗的稳定性COPD患者中未来恶化的风险之间的联系.
主要方法:
- 分析了来自韩国COPD小组研究 (KOCOSS) 队列的数据.
- 稳定的COPD患者被定义为恶化史 (在前一年中少于两次中度或没有严重的恶化).
- 血中乙氨基酸水平 (定义为高的≥300细胞/μL) 被评估为暴露,COPD中度至重度和重度急性恶化 (AECOPD) 作为结果,通过多变量Cox回归分析.
主要成果:
- 在平均12个月的随访期间,16.5%的患者患有中度至重度的AECOPD.
- 每增加100细胞/μL的血红蛋白细胞计数与14%和27%的中度至重度和重度AECOPD风险增加有关.
- 高胆固醇细胞计数与中度至重度AECOPD (aHR = 1.79) 和重度AECOPD (aHR = 1.27) 的风险增加显著相关.
结论:
- 血中乙氨基酸细胞数量的增加与COPD急性恶化 (AECOPD) 的风险增加有关.

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...

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...

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.
