Descriptive Study of Variations in Serum Translocation Markers of the Intestinal Microbiota in Patients With Gougerot-Sjögren Syndrome According to Disease Activity

Recruiting
Conditions
Sjogren's Syndrome
Interventions
Other: Biomarker detection
Registration Number
NCT04462601
Lead Sponsor
Centre Hospitalier Universitaire de Nīmes
Brief Summary

Gougerot-Sjögren syndrome or Sjögren syndrome is a chronic autoimmune disease belonging to connectivitis, the classic triad of symptoms being the association of a sicca syndrome (generally predominant in the mouth and / or ocular, but also present at the cutaneous, vaginal or tracheal level), diffuse arthromyalgia and marked fatigue. The study investigators hypothesize that changes in the gut microbiota, by modulating gut permeability and thereby promoting microbial translocation, would have immunomodulatory effects that could be correlated to changes in the activity of Gougerot-Sjögren disease.
