Treatment of Pyonephritis Complicated by Septic Shock Using Extracorporeal Device Polymyxin B-Hemoperfusion

Area of Science:

• Critical Care Medicine
• Nephrology
• Infectious Diseases

Background:

• Septic shock from Gram-negative infections is a life-threatening condition.
• Polymyxin B-immobilized fiber direct hemoperfusion (PMX-DHP) is an established treatment for Gram-negative sepsis.
• Current guidelines lack specific recommendations for PMX-DHP in certain sepsis subsets.

Observation:

• A 33-year-old woman presented with severe septic shock originating from a urinary tract infection (urosepsis).
• The patient received PMX-DHP therapy as a treatment intervention.
• Clinical improvement was observed following the PMX-DHP treatment.

Findings:

• Successful application of PMX-DHP in a case of severe urosepsis.
• Demonstration of PMX-DHP's potential efficacy beyond current guideline recommendations.
• Positive patient outcome attributed to the hemoperfusion therapy.

Implications:

• Suggests PMX-DHP may be a valuable therapeutic option for specific Gram-negative sepsis cases, including urosepsis.
• Highlights the need for further research to clarify PMX-DHP's role in sepsis management.
• Contributes to the growing body of evidence supporting the use of PMX-DHP in critical care settings.
