UNLABELLED: To describe outcomes of a cohort of patients with paediatric acute liver failure (PALF) treated with either one of two extracorporeal therapies (ECT) - continuous renal replacement therapy (CRRT) and molecular adsorbent recirculatory system (MARS®). Retrospective, observational, cohort study at two European paediatric intensive care units (PICUs) - UK (2006-2017, CRRT) and the Netherlands (2003-2017, MARS® and CRRT). Patients were children (0-18 years) admitted to the PICU with PALF who required CRRT or MARS®. Between each group, we compared baseline characteristics, biochemical parameters at 0 and 24 h after commencing MARS®/CRRT, and clinical outcomes. In total, 95 patients (23 MARS®, 72 CRRT) were included. The median age at admission for the whole cohort was 4.3 years (interquartile range (IQR) 1.0-12.1), and 47/95 (49.5%) of patients had an indeterminate aetiology. A lower proportion of patients in the MARS® group were on inotropes or were ventilated at admission, and they had a lower Pediatric Index of Mortality 3 risk % than the CRRT group (14.5% (7.5-22) vs 20.4% (16.8-26.4), p = 0.002). After treatment, there were no significant differences detected between groups in survival with native liver, or overall survival (15/23 (65.2%) for MARS® and 49/72 (68.1%) for CRRT, p = 0.998).
CONCLUSION: We did not detect a significant difference in clinical outcomes between PALF patients treated with CRRT or MARS®, despite a relatively sicker cohort in the CRRT group. Further high-quality evidence is necessary regarding the role of extracorporeal therapies in PALF, with consideration of clinical outcomes, feasibility, and cost.
WHAT IS KNOWN: • Outcomes for children with paediatric acute liver failure (PALF) have improved in recent years secondary to improved supportive care aimed at avoiding liver transplantation. • Extracorporeal therapies, in particular continuous renal replacement therapy (CRRT), are increasingly applied in the management of these children; however few studies have compared outcomes between different extracorporeal therapies.
WHAT IS NEW: • In this retrospective study across two centres, outcomes between patients with PALF treated with CRRT were compared to patients treated with MARS®. • There was no significant difference in key clinical outcomes between groups, including survival with native liver and overall survival.
