Cohort of Patients With Systemic Sclerosis and Associated Biological Collection Within the Framework of the RESO Reference Centre for Rare Systemic Autoimmune Diseases
Systemic sclerosis (SSc) is a rare form of connective tissue disease characterized by vascular involvement and the intensity of fibrosis. The lack of available treatment is largely due to the very fragmented understanding of the pathophysiology of SSc. However, one of the keys to conducting quality research on this disease remains the development of well-documented patient cohorts with reliable biological samples. The main objective of this cohort is to study the natural progression of SSc in a cohort of patients followed over 5 years.
• Patient over 18 years old
• Patient with systemic scleroderma according to the ACR/EULAR 2013 criteria, or with a very early systemic sclerosis defined by the presence of Raynaud's phenomenon and auto-antibodies in blood sample (ACAN positivity (≥1/160) with anti-Scl70, anti-centromere or anti-ARNPolIII specificity).
• Person affiliated or benefiting from a social security scheme.
• Free, informed and written consent signed by the participant and the investigator (no later than the day of inclusion and prior to any review required by the research)
