Effects of embolization on immune response in cerebral AVM patients

Impact of CErebral Endovascular PROcedures on the Systemic Immune responSe Response

Not applicable Interventional University Hospital, Limoges · NCT05621850

This study is testing how a treatment for brain blood vessel malformations affects the immune system in patients and whether it could increase their risk of infections.

What this trial studies

This study investigates how cerebral embolization procedures for treating arteriovenous malformations (AVMs) affect the immune response in patients. It focuses on the role of Dimethylsulfoxide (DMSO), a solvent used in the embolization process, and its potential impact on cytokine production. Blood samples will be collected from patients at three different time points to analyze changes in cytokine levels using multiplex ELISA techniques. The goal is to understand whether exposure to the embolization implant alters immune regulation and increases the risk of infections like Ventilator Associated Pneumoniae.

Who should consider this trial

Good fit: Ideal candidates are adults hospitalized for planned cerebral embolization of a cerebral arteriovenous malformation.

Not a fit: Patients who are immunosuppressed, have autoimmune diseases, or have had recent hospitalizations for infections or surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management strategies for patients undergoing embolization for cerebral AVMs, potentially reducing infection rates.

How similar studies have performed: While the specific approach of this study is novel, previous studies have indicated that immune responses can be affected by embolization procedures, suggesting potential relevance.
