Genomic/ Proteomic/ Metabonomic Profiling in Chronic Obstructive Pulmonary Disease (COPD)
A Non Interventional Study to Asses the Utility of Genomic/ Proteomic/ Metabonomic Profiling Approaches to the Classification and Pathological Basis of Inflammatory Lung Disease in Smokers, and Ex-smokers vs. Non-smokers and Asthmatics
Chronic obstructive pulmonary disease (COPD) is a chronic disease characterized by progressive airflow obstruction, chronic cough and dyspnoea in advanced stages.
We hope to develop a better understanding of lung disease. Information from these studies will only be used for research purposes, to help develop safer and more effective treatments for asthma and COPD.
