The Genetic Epidemiology of COPD (COPDGene) study is a noninterventional, multicenter, longitudinal analysis of > 10,000 subjects, including smokers with a ≥ 10 pack-year history with and without COPD and healthy never smokers. The goal was to characterize disease-related phenotypes and explore associations with susceptibility genes. The subjects were extensively phenotyped with the use of comprehensive symptom and comorbidity questionnaires, spirometry, CT scans of the chest, and genetic and biomarker profiling. The objective of this review was to summarize the major advances in the clinical epidemiology of COPD from the first 10 years of the COPDGene study. We highlight the influence of age, sex, and race on the natural history of COPD, and the impact of comorbid conditions, chronic bronchitis, exacerbations, and asthma/COPD overlap.
COPD(COPDGene)研究的遗传流行病学是一项非介入性、多中心、纵向分析超过 10000 名受试者的研究,包括有≥10 包年吸烟史的 COPD 患者和无 COPD 患者以及健康从不吸烟的人群。目的是描述与疾病相关的表型,并探讨与易感基因的关联。使用全面的症状和合并症问卷、肺量测定、胸部 CT 扫描以及遗传和生物标志物分析对受试者进行了广泛的表型分析。本文综述了 COPDGene 研究的前 10 年中 COPD 临床流行病学的主要进展。我们强调了年龄、性别和种族对 COPD 自然史的影响,以及合并症、慢性支气管炎、加重和哮喘/COPD 重叠的影响。
