    Abstract:
    BACKGROUND: The models for end-stage liver disease (MELD) and serum sodium (SNa) are important prognostic markers in cirrhosis. A novel index, MELD to SNa ratio (MESO), was developed to amplify the opposing effect of MELD and SNa on outcome prediction. METHODS: A total of 213 cirrhotic patients undergoing hepatic venous pressure gradient (HVPG) measurement were retrospectively analyzed. RESULTS: The MESO index correlated with HVPG (r=0.258, P<0.001) and Child-Pugh score (rho=0.749, P<0.001). Using mortality as the end point, the area under receiver operating characteristic curve (AUC) was 0.860 for SNa, 0.795 for the MESO index and 0.789 for MELD (P values all >0.3) at 3 months. Among patients with Child-Pugh class A or B, the MESO index had a significantly higher AUC compared with MELD (0.80 vs. 0.766, P<0.001). A MESO index <1.6 identified 97% of patients who survived at 3 months and the predicted survival rate was 96.5%. In survival analysis, MESO index >1.6 independently predicted a higher mortality rate (relative risk: 3.32, P<0001) using the Cox model. CONCLUSIONS: The MESO index, which takes into account the predictive power of both MELD and SNa, is a useful prognostic predictor for both short- and long-term survival in cirrhotic patients.
