Abstract
BACKGROUND/AIMS: The optimal duration of hemoperfusion therapy with a polymyxin B-immobilized fiber column has not yet been verified. METHODS: This analysis examined whether hemoperfusion therapy with a polymyxin B-immobilized fiber column lasting longer than 2 h (prolonged polymyxin) improved outcomes for patients with septic shock compared to 2-h polymyxin therapy (sub-analysis of data from the DESIRE trial). RESULTS: The 2-h and prolonged polymyxin groups contained 22 and 14 patients, respectively. Both groups had similar characteristics. The polymyxin duration per session in the prolonged polymyxin group was significantly longer (median, 5.5 h) than in the 2-h polymyxin group (p < 0.01). The 28-day mortality rate was significantly higher in the 2-h polymyxin group (7, 31.8%) than in the prolonged polymyxin group (0, 0%; p = 0.019). CONCLUSION: Prolonged polymyxin therapy might be associated with better clinical outcomes than 2-h polymyxin therapy in patients with septic shock.
