Sepsis is mediated by many biologically active inflammatory mediators, including interleukins. IL-6, IL-8, and IL-10 *P < 0.05. are correlated with increased mortality in septic shock acute renal failure (ARF) . ARF treatment requires renal replacement therapy (RRT). The cytokine plasmatic level during and after hemodialysis (HD) in septic ARF is partially described . Polymethylmethacrylate (PMMA) hemodialyser membranes own high adsorptive capacity . In this prospective observational trial, we study the plasmatic level of IL-6, IL-8 and IL-10 during and after the first HD seance with PMMA membrane in septic shock patients with ARF.
Inclusion criteria: patients with septic shock <24 hours as defined by the American College of Chest Physicians/Society of Critical Care Medecine and requiring RRT (Injury in the RIFLE criteria). The hemodialyser PMMA membrane was Filtrizer BK-1,6 F (TORAY Industrie, Tokyo, Japan). Data and blood samples were collected at: start of HD (D0), every hour during HD (D1; D2), at the end of HD (endD); and 30, 60, 90, 120 and 180 minutes after HD (postD0.5; postD1; postD1.5; postD2; postD3, respectively). Solid-phase ELISA was used for cytokine measurements. Statistical analysis was by Kruskall–Wallis nonparametric test.
PMMA membranes showed transient efficiency in IL-8 and IL-10 elimination by possible membrane saturation. The IL-6 concentration was not modified. Three hours after HD, the IL-8 and IL-10 concentrations were back to baseline. This fast increase could be explained by plasmatic rebound and must be kept in mind. This rebound could be deleterious in this stage of sepsis.
