Elevated lactate/albumin ratio as a novel predictor of in-hospital mortality in hospitalized cirrhotics

Abstract

Two hundred seventy-nine patients were included in this study. Univariate analysis revealed that mean WBC count, platelet/creatinine ratio, aspartate transaminase (AST), lactate, and MELD score were all significantly associated with the primary outcome. Multivariate analysis showed that the lactate/albumin ratio was the strongest statistically significant (p < 0.001) predictor of death during hospitalization - OR 13.196 (95% CI 3.6-48.3), followed by mean WBC count, MELD score, and serum lactate levels. A ROC curve was constructed, which resulted in an area under the curve (AUC) equal to 0.77. Crosstabs from the ROC showed a sensitivity of 66.7% and a specificity of 76.2% when the lactate/albumin ratio chosen as a cutoff was 0.9061 CONCLUSIONS: Elevated lactate/albumin ratio predicts in-hospital mortality in hospitalized cirrhotics with acute-on-chronic hepatic failure.
