RaDiCo PID Cohort (RaDiCo-ILD Cohort in English)

Recruiting

• Conditions: Paediatric and Adult Patients; Idiopathic Interstitial Pneumopathy/Pneumopathy Interstitial Diffuse

• Registration Number: NCT04238871
• Lead Sponsor: Institut National de la Santé Et de la Recherche Médicale, France

Brief Summary

The main objective is to describe the phenotypic features of the paediatric and adult patients with Idiopathic Interstitial Pneumopathy/Pneumopathy Interstitial Diffuse (IIP/PID), at diagnosis and during the follow-up. These data will be critical for the description of the natural history of the various forms of IIP/PID.

Detailed Description

The French RaDiCo-PID : Idiopathic Interstitial Pneumopathy registry is an ongoing observational prospective and retrospective cohort with longitudinal long-term follow-up includes pediatric and adult patients with Idiopathic Interstitial Lung Disease (ILD) from the reference and competence centers.

• Sex: All
• Target Recruitment: 2500

Inclusion Criteria

• Clinical criteria: chronic respiratory insufficiency manifestations including dyspnea/tachypnea, cough, and cyanosis during exercise or at rest
• Radiological criteria: characteristic chest High-Resolution Computed Tomography (HRCT) abnormalities including widespread ground glass or alveolar attenuation, reticulation often associated with traction bronchiectasis, and honeycombing

• Patients (parents/guardians for paediatric/patients) having given an informed consent to participate in the protocol
• Patients affiliated to the "Regime National d'Assurance Maladie"

Exclusion Criteria
