Exploring autoantibodies in systemic lupus erythematosus

Evaluation of Anti-C1s, Anti-HMGB1 and Anti-C1q Autoantibodies in the Pathogenesis for Patients With Systemic Lupus Erythematosus (SLE)

Observational University Hospital, Grenoble · NCT05193591

This study is trying to see how certain autoantibodies affect the immune system in people with systemic lupus erythematosus to better understand the disease and improve treatment options.

What this trial studies

This observational study investigates the role of specific autoantibodies (anti-C1s, anti-HMGB1, and anti-C1q) in patients with systemic lupus erythematosus (SLE). The research focuses on understanding how these autoantibodies interact with key proteins involved in the immune response and their potential impact on disease pathology. By evaluating the effects of these autoantibodies on various molecular interactions, the study aims to shed light on their pathogenic roles and implications for SLE management.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with a confirmed diagnosis of systemic lupus erythematosus and active lupus nephritis.

Not a fit: Patients who are minors, pregnant, breastfeeding, or undergoing dialysis or plasma exchange may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a better understanding of lupus pathology and inform new therapeutic strategies for patients with systemic lupus erythematosus.

How similar studies have performed: While the specific approach of evaluating these autoantibodies is novel, related studies have explored the role of autoantibodies in autoimmune diseases with varying degrees of success.
