Genetic Epidemiology of Chronic Obstructive Pulmonary Disease

Chronic obstructive pulmonary disease (COPD) is a long-term lung disease that is often caused
by cigarette smoking. The purpose of this study is to evaluate whether certain genetic
factors predispose some smokers to develop COPD more than others.

COPD is a disease in which the lung airways are damaged and partly obstructed, making it
difficult to breathe. Millions of people in the United States have COPD, and it is the third
leading cause of death in the United States. Symptoms include coughing, excess mucus
production, shortness of breath, wheezing, and chest tightness. Emphysema and long-term
bronchitis are the two most common manifestations of the disease. The most common risk factor
for developing COPD is cigarette smoking; however, only 15% to 20% of smokers develop COPD in
their lifetimes. It is not known why some smokers develop COPD and some do not, but certain
genetic factors, combined with exposure to cigarette smoke, may increase the likelihood of
developing COPD. This study will analyze DNA from current and former cigarette smokers to
identify genetic factors and markers that may indicate a predisposition to developing COPD.

This study will enroll African-American and white cigarette smokers and former cigarette
smokers both with and without COPD. Participants will attend one study visit during which
they will complete questionnaires about lung symptoms, breathing difficulties, medical and
family history, and quality of life. They will also undergo blood collection, a physical
exam, lung function testing, and a walking test to measure endurance. Participants will
undergo a high resolution computed tomography (CT) chest scan and a medical record review.
Study researchers will contact participants up to four times a year for 5 years to collect
follow-up medical information. A five year follow-up visit including a similar study protocol
as the baseline visit will be performed on all available subjects.

Inclusion Criteria:

- At least 10 pack-years of cigarette smoking (although a of nonsmoking controls is also
being enrolled)

- Self-designation of non-Hispanic white or African-American

Exclusion Criteria:

- Other lung diseases (except for asthma in participants with COPD)

- Pregnant

- Cancer (other than skin cancer) in the 5 years prior to study entry

- Received antibiotics for a COPD exacerbation in the 1 month prior to study entry

- First- or second-degree relative of a previously enrolled study participant
