Summary
Bacterial translocation, the movement of gut bacteria and endotoxins, may contribute to sepsis and organ failure. However, its role in human disease remains debated, potentially being an epiphenomenon rather than a direct cause.
Area of Science:
- Gastroenterology
- Immunology
- Critical Care Medicine
Context:
- Bacterial translocation (BT) involves the movement of bacteria and endotoxins from the gut to other body sites.
- BT is hypothesized to trigger or worsen sepsis and multiple organ failure (MOF).
- Evidence suggests BT occurs in humans, but its significance is debated.
Purpose:
- To review the evidence for bacterial translocation in human disease.
- To discuss the potential role of BT in the pathogenesis of sepsis and MOF.
- To explore alternative hypotheses for distant organ injury.
Summary:
- BT is defined as the passage of bacteria and endotoxins across the intestinal barrier.
- Animal studies link BT to mortality and sepsis, but human data are variable.
- Recent findings suggest the gut produces inflammatory factors, and intestinal injury can cause organ damage independently of detectable BT.
Impact:
- Clarifies the complex relationship between bacterial translocation and multiple organ failure.
- Highlights the potential role of the gut as a source of inflammatory mediators.
- Suggests that intestinal injury, not just bacterial translocation, may drive distant organ damage in critical illness.
