Fibronectin depletion and microaggregate clearance following trauma
The Journal of Trauma
|April 1, 1986
Summary
Trauma patients show significant microaggregate (MA) formation and fibronectin (Fn) depletion, correlating with injury severity. Early Fn or cryoprecipitate administration may enhance reticuloendothelial system (RES) clearance of MA.
Area of Science:
- Trauma and Emergency Medicine
- Biochemistry
- Immunology
Background:
- Trauma triggers microaggregate (MA) formation and fibronectin (Fn) depletion.
- The reticuloendothelial system (RES) plays a role in clearing these aggregates.
Purpose of the Study:
- To investigate the correlation between trauma severity, MA formation, and Fn levels.
- To explore the potential role of the RES in MA clearance post-trauma.
Main Methods:
- Blood samples from 97 trauma patients were analyzed pre-resuscitation.
- Microaggregate formation measured by screen filtration pressure (SFP).
- Plasma fibronectin (Fn) levels quantified by immunoturbimetric assay; Injury Severity Score (ISS) calculated.
Main Results:
- A significant correlation was found between trauma severity (ISS), MA formation, and Fn depletion.
- Higher ISS correlated with increased MA formation and greater Fn depletion.
Conclusions:
- Significant correlation between MA formation and Fn depletion suggests RES involvement in MA clearance after trauma.
- Early administration of purified Fn or cryoprecipitate may enhance RES clearance, potentially preventing adverse end-organ MA deposition.
