    Abstract:
    The performance of the Model for End-stage Liver Disease (MELD) and delta-MELD scores in predicting posttransplant survival has been variable and the results are conflicting, suggesting that posttransplantational factors are more important than pre- or peritransplantational factors in outcomes following liver transplantation (OLT). We assessed the value of posttransplant MELD and delta-MELD scores to predict short-term (90-day) posttransplant survival. We evaluated 279 consecutive patients undergoing living donor OLTs. The MELD scores were calculated serially from pretransplantation as well as 3, 7, and 14 days after transplantation. Twenty-seven (9.7%) among 279 patients died within 90 days after transplantation. Pretransplant MELD score was not associated with short-term posttransplant mortality. The area under the receiver operating characteristic (AUROC) curve in predicting 90-day mortality was 0.637 for posttransplant 3-day MELD, 0.746 for posttransplant 7-day MELD, and 0.859 for posttransplant 14-day MELD score (P = .047, <.001, and <.001, respectively); AUROC was 0.582, 0.646, and 0.784 for 3-day, 7-day, and 14-day delta-MELD scores (P = .235, .034, <.001, respectively). Upon multivariate analysis, posttransplant 14-day MELD (> or =20 vs <20), and 14-day delta-MELD scores (> or =-3 vs <-3) were independent short-term prognostic factors with risk ratios of 18.875 (95% confidential interval [CI]: 4.625-77.028, P < .001) and 13.577 (95% CI: 2.641-69.791, P = .002), respectively. In conclusion, determination of posttransplant 14-day MELD and 14-day delta-MELD scores may afford suitable short-term prognostic predictors for patients following living donor OLT.
