Examining Neutrophils in Sepsis Patients
Official title: Expression Profiles of Integrin αDβ2 on Neutrophils in Sepsis
Run by Boston Children's Hospital · NCT04103281 · Data updated 2026-11-12
This study looks at the white blood cells called neutrophils in the blood and breathing tubes of sepsis patients to see how they behave and if they might be causing lung problems, with the hope of finding better treatments.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include ICU patients diagnosed with sepsis who require a breathing tube.
✕Probably not a fit
Patients on chronic immunosuppressive drugs or with preexisting immunodeficiency diseases may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This observational study aims to investigate the characteristics of neutrophils found in the blood and secretions from the breathing tubes of patients suffering from sepsis. Sepsis is a severe infection that can affect multiple body systems, and neutrophils play a crucial role in the immune response. By analyzing these white blood cells, researchers hope to understand their behavior and potential harmful effects in sepsis, which could lead to the development of targeted therapies to mitigate lung injury caused by these cells.
Why it matters
Potential benefit: If successful, this study could lead to improved therapies that prevent neutrophils from causing harm in sepsis patients.
How similar studies have gone: While the specific approach of examining neutrophil profiles in sepsis is novel, similar studies have shown promise in understanding immune responses in critical conditions.
