Evaluating S100B Protein in Patients with Minor Traumatic Brain Injury on Antiplatelet Therapy

Interest of S100B Protein for Patient Victim of Minor Traumatic Brain Injury and Treated by Antiplatelet

Phase 3 Interventional Poitiers University Hospital · NCT03780062

This study is testing if the S100B protein levels in blood can help predict how well people with minor brain injuries who are on blood-thinning medication will do.

What this trial studies

This clinical trial aims to assess the negative predictive value of the S100B protein in patients who have experienced a minor traumatic brain injury while undergoing antiplatelet therapy. Patients over the age of 18 with a Glasgow Coma Scale score between 13 and 15 will be included after meeting specific inclusion criteria. Blood samples will be collected for S100B protein analysis, while standard medical care, including a CT scan, will be maintained. The study seeks to determine if S100B levels can effectively predict outcomes in this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old who have sustained a minor traumatic brain injury and are currently on antiplatelet medication.

Not a fit: Patients under 18 years old, those with more severe injuries (Glasgow score < 13), or those without social security coverage may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a reliable biomarker for assessing the risk of complications in patients with minor traumatic brain injuries on antiplatelet therapy.

How similar studies have performed: While the specific use of S100B in this context may be novel, similar studies have explored biomarkers in traumatic brain injury with varying degrees of success.
