Summary

The liver plays a critical role in host defense during sepsis by managing inflammation and coagulation. However, inadequate hepatic control can lead to dysfunction, potentially causing organ failure.

Area of Science:

  • Hepatology
  • Immunology
  • Critical Care Medicine

Background:

  • The liver is central to host defense during sepsis, involving Kupffer cells and hepatocytes.
  • Sepsis triggers acute-phase protein responses, influencing coagulation and inflammation.

Purpose of the Study:

  • To review the liver's response to sepsis.
  • To establish how this response impacts coagulation and inflammation.
  • To explore mechanisms of hepatic dysfunction in sepsis and its link to multiple organ dysfunction syndrome.

Main Methods:

  • Literature review of published medical articles.
  • Analysis of MEDLINE search files and existing reviews.
  • Focus on liver function in experimental and human sepsis.

Main Results:

  • Hepatic cells (Kupffer cells, hepatocytes) manage bacterial clearance and inflammatory mediators.
  • Acute-phase proteins modulate coagulation by affecting protein C, antithrombin, and fibrinolysis.
  • Hepatic inflammation and coagulation processes can lead to liver injury and microcirculatory disturbances.

Conclusions:

  • The liver's cross-talk between cells controls coagulation and inflammation in sepsis.
  • Inadequate hepatic control can result in secondary liver dysfunction.
  • This dysfunction may precipitate bacterial spillover, amplified inflammation, and multiple organ failure.
