概括
新的多维慢性阻塞性肺病 (COPD) 标准准确地确定了日本吸烟者患恶化的风险更高. 这些标准即使在没有空气流量限制的个体中也有效,显示出广泛的适用性.
科学领域:
- 肺部病理学 肺部病理学
- 放射学 放射学是一门学科.
- 流行病学 流行病学
背景情况:
- 新的多维慢性阻塞性肺病 (COPD) 诊断标准包括计算机断层扫描 (CT) 发现和超出空气流限制的症状.
- 这些标准是在北美队伍中开发的,由于COPD表型不同,需要在亚洲人群中验证.
- 这项研究旨在在日本吸烟者身上验证这些标准,评估他们识别患有恶化风险增加的个体的能力,特别是那些没有空气流量限制的人.
研究的目的:
- 在日本吸烟人口中验证最近提出的多维慢性阻塞性肺病 (COPD) 诊断标准.
- 确定这些标准是否可以识别日本吸烟者患恶化的风险增加,包括那些没有空气流量限制的人.
- 评估COPD评估测试 (CAT) 评分和肺气 (LAA%) 与恶化风险的相关性.
主要方法:
- 从两个前性队列 (京都-Himeji和K-CCR) 来对517名日本吸烟者 (≥40岁) 的回顾性分析.
- 数据包括胸部CT扫描和COPD评估测试 (CAT) 成绩.
- 根据主要标准 (空气流量限制) 加上≥1个次要标准,或单独≥3个次要标准 (包括肺气[LAA% ≥5%]和气道壁厚度[壁面% ≥60%]) 的COPD诊断. 使用负二项式回归分析了超过三年的恶化风险.
主要成果:
- 在517名吸烟者中,364人符合COPD的主要标准,26人满足COPD的次要标准,40人没有COPD的空气流量限制,87人属于非COPD组.
- 与非COPD组 (0.069) 相比,COPD组中每人/年恶化率最高 (主要标准为0.270,仅次要标准为0.259).
- 两组COPD都显示出明显更高的恶化风险 (调整后的IRR:仅针对次要标准为4.95;针对主要标准为3.95). 更高的CAT分数和LAA%独立地与COPD患者恶化风险增加有关.
结论:
- 新的多维COPD标准有效地确定了日本吸烟者患有恶化风险增加的情况.
- 这些标准对于识别有风险的个体,包括没有空气流限制的个体是有价值的,支持它们的跨人口适用性.
- 这项研究已在UMIN注册 (UMIN000028387).

Chronic Obstructive Pulmonary Disease-I: Introduction
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.

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: Pathogenesis and Clinical Features

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

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...
