Impact of pretransplant MELD score on posttransplant outcome in orthotopic liver transplantation for patients with acute-on-chronic hepatitis B liver failure

This study was performed to evaluate the usefulness of the model for end-stage liver disease (MELD) score in comparison with the Child-Turcotte-Pugh (CTP) score to predict short-term postoperative survival and 3-month morbidity among patients with acute-on-chronic hepatitis B liver failure undergoing orthotopic liver transplantation. METHODS: We retrospectively analyzed data from all patients undergoing orthotopic liver transplantation in our unit from December 1999 to November 2005, on the admission day MELD and CTP scores were calculated for each patient according to the original formula. We evaluated the accuracy of MELD and CTP to predict postoperative short-term survival and 3-month morbidity using receiver operating characteristic (ROC) analysis and Kaplan-Meier analysis, respectively. RESULTS: Seven of 42 patients died within 3-months follow-up. The MELD scores for nonsurvivors (32.97 +/- 7.11) were significantly higher than those for survivors (24.90 +/- 4.96; P < .05), CTP scores were significantly higher, too (12.57 +/- 0.98, 11.51 +/- 1.17; P < .05). ROC analysis identified the MELD best cut-off point to be 25.67 to predict postoperative morbidity (area under the curve [AUC] = 0.841; sensitivity = 85.7%; specificity = 60.0%), and the CTP best cut-off point was 11.5 (AUC = 0.747; sensitivity = 85.7%; specificity = 54.3%). MELD score was superior to CTP score to predict postoperative short-term survival and 3-month morbidity among patients with acute-on-chronic hepatitis B liver failure undergoing orthotopic liver transplantation. CONCLUSION: MELD score was an objective predictive system and more efficient than CTP score to evaluate the risk of 3-month morbidity and short-term prognosis in patients with acute-on-chronic hepatitis B liver failure undergoing orthotopic liver transplantation.

Child-Turcotte-Pugh versus MELD score as a predictor of outcome after elective and emergent surgery in cirrhotic patients

BACKGROUND: Cirrhotic patients who present for elective and emergent surgery pose a formidable challenge for the surgeon because of the high reported morbidity and mortality. The Child-Turcotte-Pugh (CTP) score previously has been used to evaluate preoperative severity of liver dysfunction and to predict postoperative outcome. Recently, a more objective scoring classification, the model for end-stage liver disease (MELD), has been shown to predict accurately the 3-month mortality for cirrhotic patients awaiting transplantation. We sought to compare the CTP and MELD scores in predicting outcomes in cirrhotic patients undergoing surgical procedures requiring general anesthesia. METHODS: During the study period, 40 patients with a history of cirrhosis who required elective (E) or emergent (EM) surgical procedures under general anesthesia were reviewed (E = 24, EM = 16). The preoperative CTP and MELD scores were calculated and patient short- (30-day) and long-term (3-month) outcomes were recorded. RESULTS: There was a significant difference in the 1-month and 3-month mortality rates between the emergent and elective groups (EM group: 1 mo = 19%, 3 mo = 44%; E group: 1 mo = 17%, 3 mo = 21%, P <0.05). There was good correlation between the CP and MELD scores, which was greater in the emergent groups as compared with the elective group (EM: r = 0.81; E: r = 0.65). CONCLUSIONS: Our study shows that cirrhotic patients who undergo surgery under general anesthesia have an extremely high 1- and 3-month mortality rate that progressively increases with severity of preoperative liver dysfunction. Additionally, the MELD score correlates well with the CTP score, providing a more objective predictor of postoperative mortality in cirrhotic patients undergoing surgery.     

Prognosis after liver transplantation predicted by preoperative MELD score

The model for end-stage liver disease (MELD) has been an excellent predictor of 3-month mortality among cirrhotic patients awaiting orthotopic liver transplantation (OLT). The aim of this study was to evaluate whether the preoperative MELD score predicts short-term prognosis after OLT. We enrolled 98 adult liver transplant patients performed at our center from January 2001 to December 2002. In univariate analysis of risk factors for death within 3 and 6 months after liver transplantation, serum total bilirubin, creatinine, MELD score, hyponatremia with ascites, Child-Turcotte-Pugh (CTP) score were statistically significant parameters (P < .05). By logistic regression, none of the risk factors were subjected to multivariate analysis showed statistical significance. The odds ratios of the MELD score, hyponatremia with ascites, CTP score within 3 months were 0.997, 1.151, and 0.726 with 95% confidence intervals of [0.899, 1.105], [0.102, 12.959], and [0.389, 1.352], respectively. The odds ratio of MELD score, hyponatremia with ascites, CTP score within 6 months were 0.996, 0.914, and 0.764, with 95% confidence intervals of [0.901, 1.102], [0.089, 9.369], and [0.417, 1.401], respectively. Although MELD score has been a good predictor of short-term prognosis before OLT, MELD did not show an influence on the short-term prognosis after liver transplantation in this study.

Different model for end-stage liver disease score block distributions may have a variable ability for outcome prediction

BACKGROUND: The model for end-stage liver disease (MELD) scoring system has become the prevailing criteria for organ allocation in liver transplantation. However, it is not clear if the predictive accuracy of MELD is equally homogeneous in different distribution of MELD score blocks. METHODS: We investigated 472 cirrhotic patients (mean MELD, 14.3+/-5.5), and compared the predictive accuracy of MELD and the corresponding Child-Turcotte-Pugh (CTP) scores in patients with low (<16), intermediate (10-20) and high (>14) MELD score range by using c-statistic for area under the receiver operating characteristic curve (AUC) at different time frames. RESULTS: The MELD scores well correlated with CTP scores at baseline (rho=0.492, P<0.001). Overall, MELD was significantly better than the CTP system to predict the risk of mortality. However, in stratified analysis there were no significant differences between MELD and CTP for the c-statistic in patients with low and intermediate range MELD scores at 3-, 6-, 9-, and 12-month (p values all > 0 1). Among patients with high MELD scores, MELD was consistently more accurate than the CTP system in predicting the mortality at 3- (AUC, 0.715 vs. 0.543, P=0.020), 6- (0.705 vs. 0.536, P=0.003), 9- (0.737 vs. 0.507, P<0.001) and 12-month (0.716 vs. 0.526, P<0.001), respectively. CONCLUSIONS: MELD has a better performance only in a subset of patients with higher MELD scores. The outcome in patients with lower range MELD scores cannot be reliably predicted solely with their MELD scores, and alternative prognostic markers should be used in conjunction to enhance the predictive accuracy.     

Model for End-Stage Liver Disease (MELD) Score Does Not Predict Outcomes of Hepatitis B–Induced Acute-on-Chronic Liver Failure in Transplant Recipients

BackgroundAcute-on-chronic liver failure (ACLF) is a severe clinical entity and liver transplantation is the only definitive therapy to salvage these patients. However, the timing of liver transplant for these patients remains unclear.MethodsSeventy-eight patients undergoing liver transplantation because of hepatitis B ACLF were retrospectively analyzed from June 2004 to December 2010. The areas under the receiver operating characteristic curve (AUC) of Model for End-Stage Liver Disease (MELD) score and Child-Turcotte-Pugh (CTP) score for the post-transplantation outcomes were calculated.ResultsThe median age was 44 years (range, 25–64 years), serum bilirubin 418.53 μmol/L (range, 112.90–971.40 μmol/L), INR 3.177 (range, 1.470–9.850), and creatinine 70.84 μmol/L (range, 12.39–844.1 μmol/L); the median MELD score was 32 (range, 21–53) and CTP score 12 (8–15). The AUCs of MELD and CTP scores for 3-month mortality were 0.581 (95% confidence interval [CI], 0.421–0.742; sensitivity, 87.5%; specificity, 32.8%) and 0.547 (95% CI, 0.401–0.693; sensitivity, 75%; specificity, 41%), respectively. Meanwhile, there were no significant differences in hospital mortality (P = .252) or morbidity (P = .338) between the patients with MELD score ≥30 and those <30.ConclusionsMELD score had no predictive ability for the outcomes of patients with hepatitis B ACLF after orthotopic liver transplantation.     

A systematic review of the performance of the model for end-stage liver disease (MELD) in the setting of liver transplantation.

The Model for End-Stage Liver Disease (MELD) score is now used for allocation in liver transplantation (LT) waiting lists, replacing the Child-Turcotte-Pugh (CTP) score. However, there is debate as whether it is superior to CTP score to predict mortality in patients with cirrhosis on the LT waiting list and after LT. We reviewed studies comparing the accuracy of MELD vs. CTP score in transplantation settings. We found that in studies of the LT waiting list (12,532 patients with cirrhosis), only 4 of 11 showed MELD to be superior to CTP in predicting short-term (3-month) mortality. In addition, 2 of 3 studies (n = 1,679) evaluating the changes in MELD score (DeltaMELD) showed that DeltaMELD had better prediction for mortality than the baseline MELD score. The impact of MELD on post-LT mortality was assessed in 15 studies (20,456 patients); only 6 (9,522 patients) evaluated the discriminative ability of MELD score using the concordance (c) statistic (the MELD score had always a c-statistic < 0.70). In 11 studies (19,311 patients), high MELD score indicated poor post-LT mortality for cutoff values of 24-40 points. In re-LT patients, 2 of 4 studies evaluated the discriminative ability of MELD score on post-LT mortality. Finally, several studies have shown that the predictive ability of MELD score increases by adding clinical variables (hepatic encephalopathy, ascites) or laboratory (sodium) parameters. On the basis of the current literature, MELD score does not perform better than the CTP score for patients with cirrhosis on the waiting list and cannot predict post-LT mortality.
