RaDiCo PID Cohort (RaDiCo-ILD Cohort in English) (RaDiCo-PID)

Idiopathic Interstitial Pneumopathy : Genetic and Environmental Determinants From Infancy to Elderly

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.

Study Overview

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

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.

Study Population

Patient with a diagnosis of Pneumopathie Interstitielle Diffuse/ Idiopathic Interstitial Pneumonia diagnosis is established on presenting history, clinical, radiological and functional and if available pathological findings.

Description

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
• Functional criteria: pulmonary function test abnormalities reflecting a restrictive pattern and including: loss of lung volume, vital capacity (VC), total lung capacity (TLC); reduction in the diffusion capacity of the lung for carbon monoxide (DLCO), gas exchange abnormalities, and altered ventilatory response to exercise
• 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:

• Patients with diffuse parenchymal lung diseases caused by drug toxicity, immunodeficiency, proliferative disorders including histiocytosis, and metabolic disorders
• Patients (parents/guardians for paediatric patient) not able to approve/understand the protocol

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The phenotypic description idiopathic lung disease	Phenotypic description will be measure demographic data, environmental data, socio-professionnal data, medical history, comorbidities, clinical examination, biological assessment (hematology; biochemistry; hemostasis...), pulmonary biopsy, bronchial-pulmonary imaging; symptom description; respiratory function (arterial blood gas, pulmonary fonction testing, six minute-walk testing, cardiopulmonary exercise testing, polysomnography), treatments, quality of life questionnaire (SF36 and SF10)	Up to 10 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Identify gene factors involved in disease initiation and progression	study genes : SFTPA1, SFTPA2, SFTPB, SFTPC, ABCA3, NKX-2.1, TERT, TERC, RTEL1, PARN, DKC1, TINF2, COPA, MARS, CSF2RA, CSF2RB, SERPINA1, FLCN	Up to 10 years
Investigate the extent to which environmental and co-morbidity factors may influence disease severity and outcome	environnemental data: dwellings, wet areas, dust, smoking, drugs, exposure to materials. Respiratory history, cardiovascular history, endocrinal history, dermatological history, gastroenterology history, gynecology history, haematological history, immune history, neurological history, ophtalmological history, ENT history, psychatric history, Rheumatology history, surgery history	Up to 10 years
Identify and validate biomarkers for disease diagnosis and progression	Identify and validate biomarkers for disease diagnosis and progression with Biological assessment (professionnal data, medical history, comorbidities, clinical examination, biological assessment (hematology; biochemistry; hemostasis...) and respiratory function (arterial blood gas, pulmonary fonction testing, six minute-walk testing, cardiopulmonary exercise testing, polysomnography)	Up to 10 years
