The Cohort for Research and Innovation in Chronic Inflammatory Respiratory Diseases (the RINNOPARI Project: Recherche et Innovation en Pathologie Respiratoire Inflammatoire) is a monocentric study conducted at the University Hospital of Reims, France. Adult patients (>18 year-old) followed at the University Hospital of Reims and diagnosed with COPD, ILD, bronchiectasis, or CF will be considered for inclusion. Patients will sign an informed consent for inclusion. Exclusion criteria include "subjects protected by the law" as required by the French authorities. Control patients with no respiratory diseases after clinical and pulmonary function tests assessment will be also included. The expected number of patients included is 225 (COPD, n=100; CF, n=25; bronchiectasis, n=25; ILD, n=25; controls, n=50). Inclusion will be conducted for 36 months from September 2016 (9/30/2016) to September 2019 (9/30/2019).
