Understanding the role of IL-17 in Bullous Pemphigoid

Identification and Functional Characterization of the Cellular and Molecular Actors of the IL-17B/IL-17RB Axis in Bullous Pemphigoid

Not applicable Interventional CHU de Reims · NCT06479018

This study is testing how a specific immune response related to IL-17 affects people with bullous pemphigoid to see if it can help improve treatment options.

What this trial studies

This study focuses on bullous pemphigoid, an autoimmune skin disease primarily affecting the elderly, characterized by blisters and intense itching. It aims to investigate the IL-17B/IL-17RB inflammatory response in patients diagnosed with this condition. By recruiting 90 patients from the Reims University Hospital, the study will analyze cellular and molecular factors associated with IL-17 and their role in the disease's pathophysiology. Additionally, it seeks to identify IL-17B as a potential biomarker for treatment outcomes and to understand the inflammatory profile of different clinical variants of bullous pemphigoid.

Who should consider this trial

Good fit: Ideal candidates are elderly patients diagnosed with bullous pemphigoid who meet specific clinical and laboratory criteria.

Not a fit: Patients with pemphigoid gestationis or those who have recently received corticosteroid treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more targeted therapies for bullous pemphigoid, reducing side effects associated with current treatments.

How similar studies have performed: While the role of IL-17 in autoimmune diseases is being explored, this specific approach to bullous pemphigoid is novel and has not been extensively tested.
