Corrigendum to “Effects of polymyxin B hemoperfusion on hemodynamics and prognosis in septic shock patients” [J Crit Care 43 (2018) 202–206

Abstract

PurposeWe designed this study to examine the clinical effects of polymyxin B hemoperfusion (PMX-HP) in septic shock patients. Material and methodsWe retrospectively examined the effects of PMX-HP in septic shock patients with intra-abdominal or gram-negative bacterial infection during October 2013–May 2016. A one-to-one matching between the PMX-HP and conventional groups was performed, and 28-day mortality, and change in inotropic score, Sequential Organ Failure Assessment (SOFA) score, and Acute Physiology and Chronic Health Evaluation II (APACHE II) score at 24h in the two groups were compared. In addition, multivariable regression analysis and Cox proportional hazards regression model were applied in all eligible patients. ResultsSixty-nine patients were eligible, of whom forty-eight patients were enrolled for matched cohort analysis. In matched cohort analysis, median change in inotropic score after 24h (−23 [−33-−13] vs. −12 [−19-0], p = 0.007) differed significantly between the PMX-HP and conventional groups. Multivariable regression analysis revealed that PMX-HP was associated with lower 28-day mortality (odds ratio 0.18, 95% CI 0.04–0.92, p=0.039) and greater improvement in inotropic and APACHE II scores. ConclusionsPMX-HP may have potential benefits for hemodynamic and prognostic outcomes in septic shock patients with intra-abdominal or gram-negative bacterial infection.
