ReferenceStudy typeDisease or surgeryNumber of patientsCytoSorb usage detailsPrimary endpointResultsAdverse effects

Asch et al. [77]Single-center RCTAcute infective endocarditisHA
Control
Single cartridge; intraoperatively and continued for 24 h postoperatively; no flow monitoringPostoperative course of cytokine levels (IL-6, TNF-α, and IL-1b) and infection parameters (CRP, PCT, and leucocytes)May be useful to equalize higher preoperative levels of CRP and PCT; no advantage in reducing inflammatory parameters or improving hemodynamicsNo
Bernardi et al. [69]Single-center pilot RCTElective CPB surgeryHA
Control
Single cartridge; during CPB; 200 mL/minCytokine levels
(IL-1β, IL-6, IL-18, TNF-α, and IL-10) within the first five postoperative days
No reduction in proinflammatory cytokines; no benefit on clinical outcomes; longer-lasting anti-inflammatory effect of IL-10No
Garau et al. [72]Single-center RCTElective on-pump cardiac surgeryHA
Control
Single cartridge; during CPB; 300 mL/minSerum concentrations of cytokines (IL-8, IL-6, and TNF-α) and PCTReductions in IL-8 and TNF-α and improvement in CINo
Gleason et al. [68]Multicenter RCTElective complex cardiac surgerySafety population
HA
Control
Efficacy population
HA
Control
Dual cartridges; CPB time minus 1 h; 350-600 mL/minEfficacy endpoint: change in pfHb;
Safety endpoint: device-related serious adverse events
No difference in SAEs and 30-day mortality; reductions in pfHb during the valve replacement surgery and reductions in C3a and C5a in the overall efficacy groupNo
Haidari et al. [78]Retrospective, nonrandomized studyNative mitral valve infective endocarditisHA
Control
Single cartridge; pre+intraoperative or intraoperative; no flow monitoringThe incidence of postoperative sepsis, sepsis-associated death, and 30-day mortalityReductions in incidence of postoperative sepsis and sepsis-related death, and improvement in hemodynamic outcomesNo
Hohn et al. [74]A subset of a single-center RCTOn-pump cardiac surgery (details not mentioned)Single cartridge; during CPB;

Kühne et al. [81]Case seriesEndocarditisGroup 1 (intraoperatively)
Group 2 (intra+postoperatively)
Single cartridge;
intraoperatively or intra+postoperatively; intra-op: 300-600 mL/min; post-op: 80-150 mL/min
Inflammation/infection parameters, renal function, lactate plasma levels, catecholamine, and vasopressin demandPostoperative continuation of treatment might be beneficial in group 2 patients with an obviously more pronounced disease severityNo
Mehta et al. [87]Retrospective pilot studyElective aortic surgeryHA
Control
Single cartridge; during CPB; no flow monitoringIL-6 levels, PCT, leukocyte count, CRPReductions in IL-6 and PCT; improvements in respiratory and hemodynamic parameters and ICU and hospital staysNot mentioned
Nemeth et al. [88]Propensity score-matched cohort studyOrthotopic heart transplantationHA
Control
Single cartridge; during CPB; 400-500 mL/minHemodynamic stability, postoperative inflammatory responseNo difference in inflammatory response; may be beneficial to improve organ function and hemodynamicsNo

Control
Single cartridge; during CPB; no flow monitoringKey cytokine levelsNo benefits in pro- or anti-inflammatory cytokines; no improvement in relevant clinical outcomesNo

Control
Single cartridge; during CPB; 500 mL/minIsotropy and blood product demand during reoperations within the first 24 hNo benefits in improving circulation and organ functionYes
