Materials and Methods: For this purpose, early post-operative laboratory parameters were recorded in 93 living donor liver transplant recipients, and were analyzed for their association with mortality during 1 year period. Univariate and multivariate logistic regression analyses and logistic Forward Wald and Logistic Backward Wald regression analysis were performed for predicting the survival of the recipients. Results: The calculated AUC value for the mortality in recipients was 0.762, (95% CI 0.607-0.917) (P= 0.005) for neutrophil-lymphocyte ratio, and the AUC value for albumin was 0.711, (95% CI 0.573-0.848) (P= 0.025). These dates were considered strong predictive factors and were higher than other liver functional tests. A cut-off value of total bilirubin >8.76mg/dL, was superior to standard liver tests, showing a sensitivity of 72.4 +/- 13.4% and a specificity of 84.1 +/- 4.4% for predicting 1-year lethal outcomes (P<0.001), ammonia cutoff level >190ug/dl showed 63.6 +/- 14.5% sensitivity and 87.0 +/- 4.1% specificity, the neutrophil-lymphocyte ratio achieved a sensitivity of 54.5 +/- 15.0% and a specificity of 88.4 +/- 3.9% with a cut-off value of 6.5. Conclusions: The overall diagnostic values of total bilirubin, ammonia, and neutrophil-lymphocyte ratio for predicting a 1-year lethal outcome were higher than other parameters, being 81.5%, 82.7%, and 82.7%, respectively. The combined prognostic sensitivity of albumin, total bilirubin, and neutrophil-lymphocyte ratio for 1-year survival was 91.3% (P>0.001).
