Background & Aims: Pediatric acute liver failure is a rare disorder which results in death or the need for liver transplantation in 25-50% of cases. The adults scores are unable to predict survival without liver transplantation of pediatric patients. The present study assessed the use the of indocyanine green plasma disappearance rate as a tool to predict the evolution of pediatric patients with acute liver failure. Patients and Methods: All patients met the criteria of acute liver failure according to the Pediatric Acute Liver Failure Study Group. King's College, Clichy's criteria and ICG-PDR were obtained on admission or when acute liver failure was diagnosed and repeated every 12-24 hours, respectively. Results: Thirteen out of 48 patients suffered an irreversible liver damage. Seven of them underwent a liver transplantation and 6 died on the waiting. A total of 154 ICG-PDR measurements were taken during the study (Median 12.4 %/min, r:6.2 - 26.3). The ICG-PDR was significantly lower in patients who suffered irreversible liver damage compared with those who survived without liver transplantation (median ICG-PDR 4.1 %/min; r:4.0 - 5.7 vs median ICG-PDR 20.3 %/min; r: 9.1 - 30.1; respectively. P < 0.001). Using a ROC curve the cutoff of ICG-PDR for assessing the need for liver transplantation was set at 5.9 %/min (sensitivity 92.3%, specificity 97.1%). Sensitivity, specificity, PPV, NPV and DA for ICG-PDR were higher than the King's College and Clichy's criteria. Conclusions: ICG-PDR is a powerful tool that would improve the categorization of patients with pediatric acute liver failure. © 2013 John Wiley & Sons A/S.
