There are few studies about immunological explorations in COPD. Because of the complications of lung biopsies, analyses are generally made on blood samples instead of lung tissue. No study tried to classify COPD vs Asthma vs ACOS. The investigators wondered if there were differences in biomarkers between these groups. The investigators decided to open a pilot-study among COPD patients followed in Amiens-University Hospital. Each patient will be examined and a blood-test will be performed.
