What this trial studies

This observational study aims to explore the role of Neutrophil Extracellular Traps (NETs) in patients with Systemic Sclerosis (SSC) and other connective tissue diseases. It will involve recruiting 100 SSC patients, 30 patients with other connective tissue diseases, and 130 healthy volunteers from the university hospital of Reims. Blood samples will be collected to analyze plasma, serum, and neutrophils to assess NET production and composition in relation to various complications and phenotypes of SSC. The study seeks to clarify the involvement of NETs in the pathogenesis of SSC and their potential correlation with disease manifestations.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with Systemic Sclerosis or other connective tissue diseases who are receiving care at the university hospital of Reims.

Not a fit: Patients with a history of autoimmune systemic or chronic inflammatory diseases, or those with current or past neoplastic diseases, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the mechanisms underlying Systemic Sclerosis and lead to improved diagnostic and therapeutic strategies.

How similar studies have performed: While the role of NETs in other autoimmune diseases has been explored, this specific investigation in Systemic Sclerosis is novel and has not been extensively tested.
