Quantification and Characterization of Circulating Epithelial and Endothelial Cells in Gougerot-Sjögren Syndrome, Compared to Systemic Sclerosis

NCT05528809

CompletedNA

Sponsor: University Hospital, Montpellier

Conditions: Primary Gougerot-Sjögren Syndrome, Systemic Sclerosis, Diffuse

Interventions: Blood sampling

Countries: France

Primary Gougerot-Sjögren's syndrome is a systemic autoimmune disease belonging to the group of connectivities, whose physiopathology remains largely unknown. Quantification and characterization of epithelial and endothelial circulants in Gougerot-Sjögren's syndrome could reflect the intensity of the epithelial aggression, and thus possibly constitute a biomarker.
