Pediatric chronic liver failure-sequential organ failure assessment score and outcome of acute liver failure in children

AIM OF THE STUDY: Liver transplantation remains the only definitive treatment for children with acute liver failure proven to have irreversible liver injury. Many prognostic models have been used for outcome prediction in pediatric acute liver failure to select patients in a real need of liver transplantation, but unfortunately all have shown inconsistent reproducibility and prognostic accuracy. The aim of this study was to evaluate the pediatric chronic liver failure sequential organ failure assessment (pCLIF-SOFA) score as a predictor of pediatric acute liver failure outcome. MATERIAL AND METHODS: Clinical and laboratory data of 41 children with acute liver failure admitted to the National Liver Institute – Menoufia University were collected retrospectively and used for calculation of both pCLIF-SOFA and Pediatric End-Stage Liver Disease (PELD)/Model for End-Stage Liver Disease (MELD) scores on the day of admission, then statistical analysis was performed to identify the ability of these scores to predict the outcome. RESULTS: According to the outcome, children enrolled in this study were allocated to survived (n = 16) and died (n = 25) groups, which were age and sex matched. The non-survival group had significantly higher values of both pCLIF-SOFA score (11 [7-13]) and PELD/MELD score (36 [18-42]) than those of the survival group (8 [7-11], 27.5 [15-45]; p < 0.001, p = 0.004) respectively. Both pCLIF-SOFA and PELD/MELD scores at cut-off values > 8 and > 30 respectively on admission could predict death in children with acute liver failure (ALF) with high sensitivity, but with higher specificity, positive and negative predictive values for pCLIF-SOFA. CONCLUSIONS: pCLIF-SOFA is a good predictor of death in pediatric acute liver failure.
