Bronchiectasis Clinical Trials

Chronic inflammatory pulmonary diseases, including asthma, chronic obstructive pulmonary disease (COPD), bronchiectasis, cystic fibrosis (CF), primary ciliary dyskinesia (PCD) and interstitial lung diseases (ILD) are characterised by lung inflammation and remodelling. Clinical, functional, microbiological, biological, pathological and prognostic features are highly variable and heterogeneous. Several phenotypes have been described within the same pathology, as similar phenotypic traits between different pathologies, or the coexistence of components of several diagnoses in the same patient, suggesting shared underlying mechanisms that could represent new therapeutic targets, beyond the initial medical diagnosis. The objectives of this prospective study are to analyze the phenotypic characteristics (clinical, demographic, biological, morphological, pathological, and microbiological characteristics) together with respiratory exposures and underlying mechanisms involving airway epithelium and inflammation processes in a cohort of patients diagnosed with asthma, COPD, bronchiectasis, CF, PCD and ILD.
