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

April 13, 2026 updated by: Institut National de la Santé Et de la Recherche Médicale, France

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

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

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The phenotypic description idiopathic lung disease
Time Frame: Up to 10 years
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

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Identify gene factors involved in disease initiation and progression
Time Frame: Up to 10 years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 21, 2017

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
