AbstractThe CytoSorb adsorber, a blood purification therapy, is able to remove molecules in the 5-60 kDa range which comprises the majority of inflammatory mediators and some endogenous molecules. We aimed to evaluate CytoSorb therapy on clinical outcomes in critically ill patients. A retrospective case series study, from February 2016 to May 2017, was performed in 40 patients with multiple organ failure who received CytoSorb treatment. There were 28 patients with cardiogenic shock, 2 with septic shock, 9 with acute respiratory distress syndrome, and 1 with liver failure. Nineteen patients (47%) underwent extracorporeal membrane oxygenation, 11 (27%) had an intra-aortic balloon pump, 9 (22%) were implanted with Impella, 6 (15%) had a ventricular assist device, and 18 (45%) were treated with continuous veno-venous hemofiltration. After CytoSorb treatment, total bilirubin decreased from 11.6 ± 9.2 to 6.8 ± 5.1 mg/dL (P = 0.005), lactate from 12.1 ± 8.7 to 2.9 ± 2.5 mmol/L (P < 0.001), CPK from 2416 (670-8615) to 281 (44-2769) U/L (P < 0.001) and LDH from 1230 (860-3157) to 787 (536-1148) U/L (P < 0.001). The vasoactive-inotropic score after 48 h of treatment was reduced to 10 points, P = 0.009. Thirty-day mortality was 55% and ICU mortality was 52.5% at expected ICU mortality of 80%. Our study shows that CytoSorbTM treatment is effective in reducing bilirubin, lactate, CPK and LDH, in critically ill patients mainly due to cardiogenic shock. There is a need for randomized controlled trials to conclude on the potential benefits blood purification with CytoSorb in critically ill patients.© 2018 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.
