Comparison of the Model for End-stage Liver Disease and hepatic venous pressure gradient for predicting survival in patients with decompensated liver cirrhosis / 대한간학회지

ABSTRACT

BACKGROUND/AIMS: This study compared the prognostic values of the Model for End-stage Liver Disease (MELD) and the hepatic venous pressure gradient (HVPG) in the prediction of death within 3 and 12 months in patients with decompensated liver cirrhosis. METHODS: We used data from 136 consecutive patients with decompensated cirrhosis who underwent HVPG between January 2006 and June 2008. Cox regression analysis was used to investigate the independent relationships with death of MELD and HVPG. The prognostic accuracies of MELD and HVPG were analyzed by calculating the area under the receiver operating characteristic curve (AUROC) for the occurrence of death within 3 and 12 months. RESULTS: Both MELD and HVPG were independent predictors of death [hazard ratio (HR)=1.11 and 1.12, respectively; 95% confidence interval (CI)=1.04~1.20 and 1.08-1.16]. Analysis of the AUROC demonstrated that the prognostic power did not differ between MELD and HVPG for predicting the 3-month survival (HR=0.76 and 0.68, respectively; 95% CI=0.62~0.89 and 0.52~0.84; P=0.22) or the 12-month survival (HR=0.72 and 0.73, 95% CI=0.61~0.83 and CI=0.61~0.84). CONCLUSIONS: Both MELD and HVPG are independent prognostic factors of death within 3 and 12 months in patients with decompensated liver cirrhosis, and their accuracies are similar. However, HVPG has a limited role in the prediction of death in decompensated cirrhosis due to its invasiveness and limited use.
