Severe injury increases gut permeability, a key factor in developing multiple organ failure (MOF). This heightened intestinal permeability correlates with systemic inflammation markers in critically injured patients.

Area of Science:

  • Gastroenterology
  • Trauma Surgery
  • Critical Care Medicine

Background:

  • Multiple organ failure (MOF) is a severe complication in multiply injured patients.
  • Gut permeability is a potential indicator for MOF development.
  • Systemic inflammatory response is implicated in MOF pathogenesis.

Purpose of the Study:

  • To investigate the relationship between gut permeability and the development of MOF in multiply injured patients.
  • To determine if altered gut permeability correlates with markers of systemic inflammation.

Main Methods:

  • Two groups of multiply injured patients were defined based on MOF score (≥10 points for MOF development).
  • Gut permeability was assessed using the lactulose-mannitol urinary excretion ratio.
  • Serum elastase concentrations were measured as an inflammatory marker.

Main Results:

  • Gut permeability was significantly increased in injured patients compared to normal volunteers throughout the study.
  • Patients who developed MOF (group 1) showed elevated gut permeability, although not significantly different from the non-MOF group (group 2) on day 1.
  • Increased gut permeability on days 3 and 5 correlated with serum elastase levels in patients who developed MOF.

Conclusions:

  • Severe injury leads to increased intestinal permeability.
  • Elevated gut permeability in multiply injured patients is associated with a systemic inflammatory response.
  • Gut permeability may serve as a prognostic marker for MOF development in trauma patients.
