In children, optimal timing of liver transplantation (LT) is crucial, but reliable prognostic tools for chronic liver diseases are scarce. We assessed the predictive value of galactose half-life (Gal½) for LT or death. A retrospective search of hospital database 2003-2010 revealed 92 consecutive children with chronic liver disease (36 biliary atresia) whose liver function was assessed with Gal½ measurement. Gal½, follow-up data, and liver biochemistry were recorded and pediatric/model for end-stage liver disease (P/MELD) scores calculated. Patients listed for LT or those who died within 1 year of the Gal½ measurement (Group 1) were compared to those surviving without listing (Group 2). Predictive value of Gal½ and P/MELD for listing for LT was assessed with area under the receiver operating characteristic curve (AUROC) analysis. Group 1 had markedly increased median Gal½ [17.0 (interquartile range 12.5-28.5) min] and higher P/MELD [13 (-1-23)] compared with group 2, [10.5 (9.5-12.5) min and -1 (-8-8); P < 0.001 for both]. Both Gal½ and P/MELD (P < 0.001) predicted listing or death with respective AUROCs of 0.808 (95% CI 0.704-0.913) and 0.780 (0.676-0.890), and 85% sensitivity and 69% specificity for Gal½≥12.0 min. Gal½ is a useful tool when evaluating 1-year prognosis in children with chronic liver disease.
