This should lead to a better follow-up and management (including the use of anti-fibrotic therapies in the future) of these patients and ultimately to a decrease in morbidity and mortality.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients with rheumatoid arthritis visiting their rheumatologist in South of Belgium and willing to participate', 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Diagnosis of rheumatoid arthritis according to the criteria of the American Society of Rheumatology\n* Age \\> 18 years\n* Willing to participate in the study and sign the informed consent form (ICF) of participants or their legal authorized representative\n* RAIDbio subcohort : available data for one of the following analysis of biomarkers: volatile organic compounds, induced sputum or blood markers\n* RAIDomix : available data for high resolution computed tomography of the chest\n\nExclusion Criteria: none'}, 'identificationModule': {'nctId': 'NCT06184893', 'acronym': 'RAID', 'briefTitle': 'Rheumatoid Arthritis-associated Interstitial Lung Disease Definition', 'organization': {'class': 'OTHER', 'fullName': 'Centre Hospitalier Universitaire de Liege'}, 'officialTitle': 'Multi-centric Prospective and Observational Study of Prevalence and Incidence of Interstitial Lung Diseases in Patients With Rheumatoid Arthritis', 'orgStudyIdInfo': {'id': '2022/52'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'General cohort'}, {'label': 'RAIDbio', 'description': 'Sub-cohort studying biomarkers: volatile organic compounds, induced sputum and blood biomarkers'}, {'label': 'RAIDomix', 'description': 'Sub-cohort studying radiomic patterns (based on high resolution computed tomography of the chest)'}]}, 'contactsLocationsModule': {'locations': [{'zip': '4000', 'city': 'Liège', 'status': 'RECRUITING', 'country': 'Belgium', 'contacts': [{'name': 'Julien Guiot', 'role': 'CONTACT', 'email': 'j.guiot@chuliege.be', 'phone': '00324/3237881'}, {'name': 'Anna Denis', 'role': 'CONTACT', 'email': 'anna.denis@chuliege.be', 'phone': '00324/3237881'}], 'facility': 'Centre Hospitalier Universitaire de Liege', 'geoPoint': {'lat': 50.63373, 'lon': 5.56749}}], 'centralContacts': [{'name': 'Julien Guiot, PhD', 'role': 'CONTACT', 'email': 'j.guiot@chuliege.be', 'phone': '00324/323 7881'}, {'name': 'Anna Denis, MD', 'role': 'CONTACT', 'email': 'anna.denis@chulige.be', 'phone': '00324/323 7881'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Centre Hospitalier Universitaire de Liege', 'class': 'OTHER'}, 'collaborators': [{'name': 'Boehringer Ingelheim', 'class': 'INDUSTRY'}], 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Medical doctor', 'investigatorFullName': 'Denis Anna', 'investigatorAffiliation': 'Centre Hospitalier Universitaire de Liege'}}}}
