To describe etiology, short-term outcomes and prognostic accuracy of serial PELD scores in PALF. Retrospective analysis of children aged 16yr, admitted with PALF under the QLTS, Brisbane, Australia, between 1991 and 2011. PELD-MELD scores were ascertained at three time points (i) admission (ii), meeting PALF criteria, and (iii) peak value. Fifty-four children met criteria for PALF, median age 17months (1day15.6yr) and median weight 10.2kg (1.957kg). Etiology was known in 69%: 26% metabolic, 15% infective, 13% drug-induced, 6% autoimmune, and 9% hemophagocytic lymphohistiocytosis. Age<3months and weight <4.7kg predicted poor survival in non-transplanted children. Significant independent predictors of poor outcome (death or LT) were peak bilirubin>220m/L and peak INR>4. Serial PELD-MELD scores were higher in the 17 (32%) transplant recipients (mean: [i] 26.8, [ii] 31.8, [iii] 42.6); highest in the 12 (22%) non-transplanted non-survivors (mean: [i] 31.6, [ii] 37.2, [iii] 45.7) compared with the 25 (46%) transplant-free survivors (mean: [i] 25.3, [ii] 26.0, [iii] 30.3). PELD-MELD thresholds of 27 and 42 at (ii) meeting PALF criteria and (iii) peak predicted poor outcome (p<0.001). High peak bilirubin and peak INR predict poor outcome and serial PELD-MELD is superior to single admission PELD-MELD score for predicting poor outcome.
