[Biliary sepsis: some peculiarities of pathogenesis]

Area of Science:

• Hepatology
• Immunology
• Sepsis Pathophysiology

Background:

• Obstructive jaundice and cholangitis are significant risk factors for biliary sepsis.
• Specific immune and hemodynamic alterations contribute to the unique clinical presentation of biliary sepsis.

Purpose of the Study:

• To investigate the pathogenic factors influencing the course of biliary sepsis.
• To compare clinical findings with experimental data in rats with obstructive jaundice.

Main Methods:

• Clinical study of 87 patients with biliary sepsis.
• Experimental study on 54 rats with obstructive jaundice and cholangitis.
• Comparison of own data with existing literature.

Main Results:

• Obstructive jaundice induces gut bacterial and endotoxin translocation, leading to portal endotoxemia.
• Reduced reticuloendothelial system (RES) and Kupffer cell function allow systemic endotoxin entry.
• Liver ischemia, abscess formation, and portal blood shunting exacerbate systemic endotoxemia.
• These factors contribute to rapid liver abscess development and multiorganic failure.

Conclusions:

• Immune and portal hemodynamic changes are key pathogenic factors in biliary sepsis.
• Etiologic and pathogenic factors should be incorporated into the diagnosis of septic patients.
