Description of intervention(s) / exposure
Diagnosis / Prognosis - Blood sampling, FeNO, bronchoalveolar lavage, bronchoscopic tissue sampling

Patients with COPD - The following parameters are to be evaluated:

* Blood eosinophils
* FeNO
* Eosinophils in bronchoalveolar lavage
* Tissue eosinophilia (protected specimen brush sampling, endobronchial biopsy)

Patients with asthma - The following parameters are to be evaluated:

* Blood eosinophils
* FeNO
* Eosinophils in bronchoalveolar lavage
* Tissue eosinophilia (protected specimen brush sampling, endobronchial biopsy)


Diagnosis / Prognosis: Blood sampling, FeNO, bronchoalveolar lavage, bronchoscopic tissue sampling
Blood sampling (eosinophil count; eosinophilia is defined as \>300/µl (or \>150/µl during oral glucocorticosteroid treatment); FeNO: Measurement of fractional nitric oxide (NO) concentration in exhaled breath; Bronchoscopy: BAL: total leukocyte counts and leukocyte differential counts including eosinophils, PSB sampling: eosinophil count/100 cells, endobrochial biopsy: tissue eosinophil count/100 cells.
