  Purpose

Chronic obstructive pulmonary disease (COPD) is a common inflammatory disease of the airway affecting approximately 10% of individuals aged 40 years or more with a smoking history. The disease is characterized by an increase in numbers of airway white blood cells (neutrophils, lymphocytes and monocytes). Stimulation of white blood cells results in the release of different agents of inflammation. Some of these agents give an indication of the presence or severity of a disease when measured.

This case control study will be conducted at The Heart Lung Centre, London, UK. The study aims to determine biomarkers for the differentiation of subjects with COPD (GOLD Stage 1-2 and who are current smokers with a ≥ 10 pack year smoking history) and three matched control groups: one of non-smoking subjects (never smoked), one of ex-smokers and one of current smokers. COPD subjects will be matched to the non-COPD subjects by gender, age and ethnicity.

The study will include a range of physiological measurements including lung function, computerized tomography scans (CT scans), cardio pulmonary exercise test and computerized multichannel lung sounds analysis (Stethographics). In addition, lung inflammation will be assessed by cellular and molecular biomarkers using e.g. transcriptomics and proteomics technologies.

Groups/Cohorts
Group 1: COPD GOLD Stage 1-2
Sixty subjects with a clinical diagnosis of COPD, according to the GOLD guidelines (Stages 1-2), who are current smokers with at least a 10 pack-year smoking history.
Group 2: Current Cigarette Smokers
Sixty subjects who are current smokers with at least a 10 pack-year smoking history and matched to the COPD cases by ethnicity, gender and age (within 5 years).
Group 3: Ex-Smokers
Sixty subjects who are ex-smokers with at least a 10 pack-year smoking history who have not smoked for at least one year and matched to the COPD cases by ethnicity, gender and age (within 5 years).
Group 4: Never Smokers
Sixty subjects who have never smoked (non-smokers) and matched to the COPD cases by ethnicity, gender and age (within 5 years).

Detailed Description:

At the screening visit, subject consent will be obtained prior to conducting any study related procedures. Informed consent may be obtained on registration/review visit at the Centre where it is conducted and thus prior to visit 1.

The screening visit will involve obtaining demographic data and medical history information as well as performing safety assessments such as vital sign measurements, electrocardiogram (ECG), and clinical laboratory tests. An induced sputum sample will be obtained to ensure that subjects can produce an adequate sputum sample. Smokers will receive information on smoking cessation at the screening visit and follow-up telephone call.

Subjects will come back to the center on up to four further occasions if they meet the inclusion/exclusion criteria at screening:

  • visit 2: 4 to 21 days after screening,
  • visit 3: 3-14 days post visit 2, and
  • visit 4: 3-14 days post visit 3.

A follow-up telephone call will be conducted 3-10 days post visit 4.
