Investigating immunothrombosis in septic shock patients needing kidney support

Investigation of Immunothrombosis in Intensive Care Patients With Septic Shock Undergoing Renal Replacement Therapy With the OXIRIS Membrane

Observational University Hospital, Bordeaux · NCT06440317

This study is trying to see how a special type of blood filter can help patients with septic shock and kidney problems by looking at how their immune system and blood clotting work together.

What this trial studies

This observational study focuses on patients with septic shock who require renal replacement therapy. It aims to understand the role of immunothrombosis in sepsis, particularly how neutrophils and platelets contribute to organ dysfunction. The study will utilize specific hemofiltration membranes, including the oXiris membrane, to assess their impact on coagulation and immune responses in these critically ill patients. By analyzing the effects of these interventions, the study seeks to provide insights into improving patient outcomes in sepsis management.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are admitted to the ICU with septic shock and require renal replacement therapy.

Not a fit: Patients who do not meet the criteria for septic shock or those who are not in need of renal replacement therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for septic shock patients, potentially enhancing their recovery and survival rates.

How similar studies have performed: Other studies have explored similar approaches in sepsis management, indicating potential for success, though this specific methodology may be novel.
