Title: A Multicentre 3 Year Longitudinal Prospective Study to Identify Novel Endpoints and Compare These With Forced Expiratory Volume in 1 Second (FEV1) for Their Ability to Measure and Predict COPD Severity and Its Progression Over Time
Brief Summary: This is a 3 year longitudinal study to identify novel endpoints and compare these with standard measures such as forced expiratory volume in 1 second (FEV1) for their ability to measure and predict COPD (Chronic Obstructive Pulmonary Disease) severity and its progression over time. Control subjects (smokers and never smokers) will be recruited as comparators with the COPD subjects.

* History of asthma
* Significant or unstable co-morbidity
* Participated in another study 4 weeks before admission

* Known hypersensitivity to prednisolone

* A signed and dated written informed consent is obtained prior to participation
* Able to comply with the requirements of the protocol and be available for study visits over 3 years

Control Subjects - Current/Ex Smokers

* A signed and dated written informed consent is obtained prior to participation.
* Able to comply with the requirements of the protocol and be available for study visits over 3 years

Control Subjects - Non-smokers

* A non-smoking control subject will be eligible for inclusion in this study only if all of the following criteria apply:

* Baseline (post-bronchodilator) FEV1 \>85% of predicted normal. FEV1/FVC ratio \>70%
* Non-smokers with a smoking history of \< 1 pack-year (number of pack years = (number of cigarettes per day / 20) x number of years smoked).
* A signed and dated written informed consent is obtained prior to participation.
* Able to comply with the requirements of the protocol and be available for study visits over 3 years

Exclusion Criteria:

COPD Subjects
