    Abstract:
    BACKGROUND: An ideal definition of early allograft dysfunction (EAD) after live donor liver transplantation (LDLT) remains elusive. The aim of the present study was to compare the diagnostic accuracies of existing EAD definitions, identify the predictors of early graft loss due to EAD, and formulate a new definition, estimating EAD-related mortality in LDLT recipients. METHODS: Consecutive adult patients undergoing elective LDLT were analyzed. Patients with technical (vascular, biliary) complications and biopsy-proven rejections were excluded. RESULTS: There were 19 deaths due to EAD of a total of 304 patients. On applying the existing definitions of EAD, we revealed their limitations of being either too broad with low specificity or too restrictive with low sensitivity in patients with LDLT. A new definition of EAD-LDLT (total bilirubin >10 mg/dL, international normalized ratio [INR] > 1.6 and serum urea >100 mg/dL, for five consecutive days after day 7) was derived after doing a multivariate analysis. In receiver operator characteristics analysis, an AUC for EAD-LDLT was 0.86. The calibration and internal cross-validation of the new model confirmed its predictability. CONCLUSION: The new model of EAD-LDLT, based on total bilirubin >10 mg/dL, INR >1.6 and serum urea >100 mg/dL, for five consecutive days after day 7, has a better predictive value for mortality due to EAD in LDLT recipients.
