Multiple visceral lesions involving these two processes make up the severity of this disease. Its dermatological involvement is a fundamental clinical element.\n\nSystemic sclerosis is mainly divided into two subtypes, depending on the extent of dermatological involvement: limited and diffuse systemic sclerosis. These also differ in certain autoantibody profiles and clinical features. Nevertheless, it is still necessary to determine certain criteria, markers, making it possible to distinguish at an early stage the presence of limited or diffuse systemic sclerosis. The latter being characterized by more severe organic and cutaneous involvement and excess mortality. This would allow for more aggressive management from the outset at an early onset of the disease.\n\nIn general, it is known that this pathology is characterized by dysfunction of endothelial cells (EC) and fibroblasts as well as autoimmunity. Many mediators contribute to the fibroblast activation observed in SSc. However, transforming growth factor beta (TGFβ) is considered to be the central regulatory factor of fibrosis processes.\n\nIt is also known that endothelial cells interact with mast cells through the production of Stem Cell Factor (SCF) to induce their proliferation and differentiation. The damaged skin tissues in systemic sclerosis are infiltrated in particular by mast cell cells which produce TGFβ.\n\nThe team of Kihira et al (1998) demonstrated the presence of a high level of SCF in the serum of patients with systemic sclerosis.\n\nFew studies explore this possible production pathway of TGFβ in systemic sclerosis via SCF assay.\n\nThis study will allow the investigators to:\n\n* study this possible route of fibrosis through the dosage of SCF in the serum of patients suffering from systemic sclerosis\n* describe SCF as a possible biomarker of skin involvement by hypothesizing that the dosage of SCF will be higher in patients with diffuse scleroderma compared to those with limited scleroderma'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Patients followed regularly at CHU Brugmann in Rheumatology/Dermatology for limited or diffuse systemic sclerosis in accordance with the ACR/EULAR 2013 criteria.', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Patients followed regularly at CHU Brugmann in Rheumatology/Dermatology for limited or diffuse systemic sclerosis in accordance with the ACR/EULAR 2013 criteria.\n* Control patients recruited among patients followed for mechanical pathology in rheumatology\n\nExclusion Criteria:\n\n* Patients with comorbidities of hematological diseases, asthma or severe chronic renal failure (GFR \\< 30)'}, 'identificationModule': {'nctId': 'NCT05482594', 'briefTitle': 'Stem Cell Factor, a Potential Biological Marker of Skin Involvement in Systemic Sclerosis?', 'organization': {'class': 'OTHER', 'fullName': 'Brugmann University Hospital'}, 'officialTitle': 'Stem Cell Factor, a Potential Biological Marker of Skin Involvement in Systemic Sclerosis?', 'orgStudyIdInfo': {'id': 'CHUB-SCF'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Systemic sclerosis', 'description': 'Patients followed regularly at CHU Brugmann in rheumatology/Dermatology for limited or diffuse systemic sclerosis in accordance with the ACR/EULAR 2013 criteria.', 'interventionNames': ['Diagnostic Test: ELISA', 'Diagnostic Test: Videocapillaroscopy']}, {'label': 'Control', 'description': 'Control patients recruited among patients followed for mechanical pathology in rheumatology.', 'interventionNames': ['Diagnostic Test: ELISA', 'Diagnostic Test: Videocapillaroscopy']}], 'interventions': [{'name': 'ELISA', 'type': 'DIAGNOSTIC_TEST', 'description': 'During routine blood sampling, serum after centrifugation will be stored and frozen at -80°C in the immunology laboratory in order to carry out analyzes by the ELISA method to measure the levels of SCF.', 'armGroupLabels': ['Control', 'Systemic sclerosis']}, {'name': 'Videocapillaroscopy', 'type': 'DIAGNOSTIC_TEST', 'description': 'Videocapillaroscopy is a non-invasive and safe method for the morphological examination and the analysis of abnormalities of the microcirculation linked in particular to systemic scleroderma.
