Abstract

-Background : The high mortality of cirrhosis is a global public health problem. For predicting the outcome of patients with cirrhosis, many prognostic models were proposed. The new Model for End-Stage Liver Disease including serum sodium (MELD-Na) has been proposed as an alternative to the original MELD, to increase the accuracy of the score in predicting short-term mortality. The purpose of this study was to assess the ability of MELD-Na scoring system to predict three-month mortality among cirrhotic patients, and comparing it to the MELD score. -Methods: An observational study was carried out, at the Hepato-Gastro-Enterology Department of the University Hospital Center of Oran. A retrospective review of the medical records of all patients with cirrhosis, between 1st January 2019 and 31st December 2021, was performed. Among 103 patients, 47 were selected after excluding the patients who were lost to follow-up after three months or with missing data. The information collected included demographic data, clinical characteristics and laboratory values of: bilirubin, creatinine, international normalized ratio (INR) of prothrombin and sodium. The MELD-Na and MELD scores were calculated using online calculators, then the ability of the models to predict the risk of mortality at three months was assessed, using the area under the receiver operating characteristic curve (AUC). -Results: Eight (17%) patients died at three months. The MELD-Na and MELD both had significantly high area under the curve (AUC): MELD-Na: 0.952, 95% confidence interval [CI]: 0.885–1.00, MELD: 0.931, 95% confidence interval [CI]: 0.834–1.000. The MELD-Na score was slightly better than the MELD, with a sensitivity and a specificity of 87.5％ and 87.2％, respectively, for a cut-off value = 21. -Conclusion: The MELD-Na score seems to be a good predictor of mortality at three months among patients with cirrhosis.
