Current progress of research on intestinal bacterial translocation

Area of Science:

• Gastroenterology
• Critical Care Medicine
• Microbiology

Background:

• The intestinal tract maintains a dynamic equilibrium with gut flora under normal conditions.
• Damage to the intestinal barrier can lead to bacterial translocation (BT), a significant factor in multiple organ dysfunction syndrome (MODS).
• Intestinal flora and endotoxin translocation are primary sources of inflammation and MODS initiation.

Purpose of the Study:

• To review the mechanisms, detection, prevention, and treatment of bacterial translocation (BT).
• To explore the relationship between BT and parenteral diseases.
• To highlight the importance of intestinal barrier integrity in preventing BT and MODS.

Main Methods:

• Literature review of mechanisms, detection techniques, and therapeutic strategies for bacterial translocation.
• Analysis of the role of the intestinal tract as both the initiator and target organ in MODS.
• Evaluation of treatments including primary disease elimination, maintaining intestinal blood supply, early enteral nutrition, and selective digestive decontamination.

Main Results:

• Bacterial translocation (BT) is a critical pathway linking intestinal barrier dysfunction to systemic inflammation and MODS.
• Maintaining intestinal mucosal barrier integrity is essential for preventing BT.
• Early diagnosis and intervention strategies for BT show promise in managing various diseases.

Conclusions:

• Ensuring intestinal barrier integrity is paramount for preventing bacterial translocation (BT) and subsequent multiple organ dysfunction syndrome (MODS).
• Effective treatments involve addressing the primary cause, supporting intestinal viability, and implementing early nutritional and decontamination strategies.
• Targeting BT represents a significant avenue for therapeutic intervention in critical illness and related conditions.
