Understanding how trauma affects the gut and bone marrow

Official title: The Role of Brain-Bone Marrow-Gut Interaction Following Major Trauma

Run by University of Florida · NCT06606119 · Data updated 2026-11-12

This study looks at how stress and inflammation after a major trauma affect the gut and bone marrow to see if they contribute to ongoing anemia and recovery issues in trauma survivors.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older who have experienced severe blunt trauma with significant injuries.

Probably not a fit

Patients not expected to survive beyond 48 hours or those with pre-existing hematological diseases may not benefit from this study.

What this trial studies

This observational study investigates the interactions between stress, chronic inflammation, and bone marrow dysfunction following major trauma. It focuses on how these factors contribute to persistent anemia and changes in the gut microbiome, which can significantly impact long-term recovery. By collecting data and tissue samples from patients who have experienced severe trauma, the study aims to establish a foundation for future clinical interventions that could improve outcomes for trauma survivors.

Why it matters

Potential benefit: If successful, this study could lead to improved recovery strategies for patients suffering from the long-term effects of severe trauma.

How similar studies have gone: While the specific interactions being studied may be novel, previous research has indicated that understanding the relationship between trauma, inflammation, and recovery can lead to meaningful advancements in patient care.
