Frontiers in medicine·2023

Endotoxin hemoadsorption therapy improved hemodynamics in patients with septic shock. While effective, this treatment using a PMX column requires monitoring for decreased platelet counts.

Area of Science:

  • Critical Care Medicine
  • Nephrology
  • Sepsis Research

Background:

  • Perforative peritonitis with multiple organ failure is a critical condition.
  • Septic shock, characterized by hypotension, necessitates effective interventions.
  • Endotoxemia plays a significant role in the pathophysiology of sepsis.

Purpose of the Study:

  • To evaluate the efficacy of endotoxin hemoadsorption therapy using a polymyxin B-immobilized fiber (PMX) column.
  • To assess the impact of PMX hemoadsorption on hemodynamic parameters in patients with septic shock.
  • To investigate changes in inflammatory markers and endothelial cell function during therapy.

Main Methods:

  • A cohort of 31 patients with perforative peritonitis and multiple organ failure was studied.

  • Endotoxin hemoadsorption therapy with a PMX column was initiated when systolic arterial pressure fell below 90 mm Hg.
  • Hemodynamic parameters, platelet count, cytokine levels (IL-6), and vascular endothelial cell function markers (PAI-1) were monitored.

    • Main Results:

    • Significant improvements in systolic, diastolic, and mean arterial pressures were observed post-therapy.
    • A decrease in platelet count below 50,000/mm(3) occurred in 30% of patients.
    • Levels of interleukin-6 and plasminogen activator inhibitor-1 significantly decreased.

    Conclusions:

    • Endotoxin hemoadsorption therapy with a PMX column demonstrates favorable effects on hemodynamic status in septic shock.
    • The therapy effectively reduces key inflammatory markers and improves endothelial function.
    • Careful monitoring of platelet count is essential during endotoxin hemoadsorption treatment.
