Background
In 2016, the definitions of sepsis and septic shock were reviewed by the Society of Critical Care Medicine and Sequential Organ Failure Assessment (SOFA) and a quick SOFA score was added to those definitions. Direct hemoperfusion therapy with polymyxin B-immobilized fiber cartridge (PMX-DHP) has been widely used to treat sepsis and septic shock. However, prognostic factors are not well understood. We retrospectively assessed the prognostic factors of patients who had received PMX-DHP for sepsis and septic shock.
Methods
Data on 71 patients with severe infection who had undergone PMX-DHP from January 2006 to August 2015 were included in this study. Participants were re-evaluated according to the criteria of the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) and all were confirmed to satisfy the new definition of sepsis. The patients were divided into groups based on having survived (n=59) or not survived (n=12) for 28 days after PMX-DHP. Clinical data before and after PMX-DHP were compared between the two groups.
Results
In the non-survivor group, the Glasgow Coma Scale score before PMX-DHP was significantly lower than in the survivor group (12 [6 to 14] vs 14 [12 to 15], P<0.01). Furthermore, pH after the first PMX-DHP session was significantly lower in non-survivors than in survivors (7.28±0.23 vs 7.39±0.06, P=0.03). The only factor identified by multivariate analysis as significantly associated with 28-day mortality was pH after the first PMX-DHP session (odds ratio, 0.93; 95% CI, 0.83–0.99; P=0.02).
Conclusion
pH after the first PMX-DHP session is an independent risk factor for mortality in patients receiving PMX-DHP for sepsis and septic shock.
