Investigating immune responses in patients with low platelet counts

Role of Fcgamma Receptors in Immune Thrombocytopenia (ITP)

Observational Centre Hospitalier Universitaire Dijon · NCT02821572

This study is trying to understand how the immune system works in people with low platelet counts due to immune thrombocytopenia, by looking at certain immune cells in their blood and spleen.

What this trial studies

This observational study aims to explore the role of Fcgamma receptors in patients with immune thrombocytopenia (ITP), an autoimmune condition characterized by low platelet counts. The research will compare the expression of these receptors on circulating monocytes and splenic macrophages in individuals diagnosed with ITP. Blood and spleen samples will be collected from participants to analyze the immune response and its implications in the disease. The study seeks to enhance understanding of the mechanisms underlying ITP and potentially inform future therapeutic strategies.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years with a diagnosis of immune thrombocytopenia and a platelet count of less than 100 G/L.

Not a fit: Patients with autoimmune diseases other than ITP or those under guardianship may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and management of immune thrombocytopenia, potentially benefiting patients through better-targeted therapies.

How similar studies have performed: While the specific role of Fcgamma receptors in ITP is being explored, similar studies in other autoimmune diseases have shown promising results, suggesting potential for success in this area.
