Study: NCT02308267

Intervention type: OTHER
Intervention: Lung explants
Description: Lung explants from end-stage CF, which were obtained for a reason independent from the study in the Paris (Prof Burgel) and Leuven (Prof Dupont) centres will be analysed for pIgR and IgA expression as well as for Pseudomonas aeruginosa colonization. Some lung explants from control patients will also be obtained from the Leuven centre.

Intervention type: OTHER
Intervention: Sputum, nasal fluid and serum
Description: Sputum, nasal (fluid) and serum samples from CF patients and controls patients will be collected (Leuven, Paris, Torino, Verona and Saint-Luc Brussels) for S-IgA and microbiological assays. Spontaneous sputum will be collected, while nasal fluid will be sampled through nasal lavage. Control subjects will consist of COPD patients and healthy subjects (smokers or not).

Intervention type: PROCEDURE
Intervention: Bronchoscopy
Description: Endobronchial biopsies (EBB) and broncho-alveolar lavage (BAL) will be sampled at the KULeuven centre (Prof Dupont) in some CF patients (homozygous for the DF508 mutation) and colonized or not with Pseudomonas aeruginosa and who must have a general anaesthesia for a reason independent from the study. In these patients, a bronchial endoscopy will be performed during narcosis to take EBB (n=8) and BAL (2x50mL). If possible, nasal and rectal biopsies will also be performed in some patients. Samples will be assessed for pIgR and IgA expression and for primary broncho-epithelial cultures (carried out at the UCL centre, Pr Pilette). Control subjects will be patients without CF and without evidence of lung disease and who are undergoing narcosis for an independent reason at the KULeuven centre.
