Functional and histopathologic changes in the liver during sepsis.

    Summary

    Sepsis commonly causes liver failure in critically ill patients. This study reveals midzonal and peripheral liver necrosis as characteristic histologic changes in sepsis, potentially due to lost factors maintaining liver structure and function.

    Area of Science:

    • Hepatology
    • Pathology
    • Critical Care Medicine

    Background:

    • Liver failure is a common complication in critically ill patients with sepsis.
    • Histologic changes in the liver during sepsis are not well-documented.

    Purpose of the Study:

    • To examine the liver histopathology in patients who died from clinical sepsis.
    • To correlate specific clinical or treatment features with observed histopathologic changes.

    Main Methods:

    • Histopathologic examination of liver tissue from 19 patients deceased from clinical sepsis.
    • Analysis of clinical data including pathogen, nutritional support, and blood pressure.

    Main Results:

    • Midzonal and peripheral hepatocellular necrosis (moderate to marked) was observed in 11 of 19 patients.

  • Acute inflammation and cholestasis were also significant findings.
  • The severity of necrosis was not correlated with the specific pathogen, nutritional support, or arterial blood pressure.

    • Conclusions:

    • Hepatocellular necrosis is a characteristic finding in sepsis.
    • Sepsis-induced liver damage may result from the loss of factors essential for maintaining liver integrity and function.
