Conditions
Summary
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.
