    In trauma patients, complement activation and elastase levels correlate with injury severity, organ failure, and mortality. Plasma elastase best predicts acute respiratory distress syndrome and severity of multiple organ failure.

    Area of Science:

    • Biochemistry
    • Immunology
    • Trauma Medicine

    Background:

    • Trauma triggers complex inflammatory responses.
    • The complement system and granulocytes play roles in post-injury complications.

    Purpose of the Study:

    • To investigate the relationship between complement activation, granulocyte markers, and clinical outcomes in trauma patients.
    • To identify key predictors of severe post-traumatic complications.

    Main Methods:

    • Weekly measurement of complement proteins, activation products, and various blood markers in 71 trauma patients.
    • Correlation analysis of measured markers with injury severity, adult respiratory distress syndrome (ARDS), multiple organ failure (MOF), and mortality.

    Main Results:

    Related Experiment Videos

  • Complement activation and elastase levels correlated significantly with injury severity, ARDS development, MOF severity, and mortality.
  • Plasma elastase was the strongest predictor of ARDS and correlated best with injury and MOF severity.

    • Conclusions:

    • Post-traumatic complement activation leads to granulocyte activation, microvascular injury, and organ failure.
    • Elastase levels serve as a crucial indicator of trauma severity and predictor of adverse outcomes.
