Background: Extracorporeal treatment may be useful during sepsis, but definitive recommendations are lacking. Aim of this study is to review retrospectively the medical records of septic patients submitted to continuous renal replacement therapy (CRRT) with the adsorbing membrane oXiris and evaluate (1) the safety of the device, (2) the cardiorenal response, and (3) the immunological response. Materials and Methods: The medical records of 60 septic patients submitted to CRRT with the membrane oXiris from April 2011 to December 2018 have been reviewed. The adsorbing membrane oXiris® (Baxter, IL, USA) was used through a Prisma plataform (Prismaflex – Baxter, IL, USA). At basal time (T0), at 24 h (T1), and at the end of the treatment (T2) were analyzed the clinical data, the cytokines, and the time course of endotoxin. Results: Sixty patients were included in the study. In total, 85% of patients had acute kidney injury (AKI). Every CRRT treatment was of 72 ± 13 h, with the consumption of 3.2 ± 1 filters. No AE events were reported. The main cardiorenal and respiratory parameters improved with a decrease of the noradrenaline dosage. Cytokines, procalcitonin, and endotoxin activity assay decreased too. SOFA total improved from 12.4 ± 2 to 9 ± 2. Conclusion: In sepsis/septic shock patients with AKI, CRRT with the adsorbing membrane oXiris may be safe and improves the cardiorenal – function and the clinical condition. The effect on cytokines and endotoxin may explain in part these results. A RCT is warranted to confirm these data.

In anemic patients (Hb<13 g/dL), a single high dose of HRE administered 2 days before cardiac surgery is effective in reducing the incidence of aRBCt without increasing adverse events.

The age, creatinine, ejection fraction score provides an accuracy level comparable to that of the European System for Cardiac Operative Risk Evaluation, with far superior clinical performance.
