[Value of the monocyte-to-lymphocyte ratio in the prognostic evaluation of hepatitis B-related acute-on-chronic liver failure].

To investigate the predictive value of the monocyte-to-lymphocyte ratio (MLR) for survival in patients with hepatitis B-related acute-on-chronic liver failure (HBV-ACLF). 92 cases with HBV-ACLF who were admitted to the General Hospital of Western Theater Command from October 2014 to October 2017 were selected. Clinical indicators were retrospectively collected, and their survival condition was followed up for 90 days, with the end point as death or liver transplantation. MLR levels predictive value among patients after 90 days of involvement was compared by analyzing the differences between the survival and death groups and its correlation with various indicators of liver function for prognosis. 92 cases were included in this study, with a 90-day survival rate of 52% (48/92), and a mortality rate of 48% (44/92). MLR for survival and death groups were 0.520 (0.310, 0.828) and 0.740 (0.440, 1.120), respectively. MLR level was significantly higher in the death than survival group (<0.05). Receiver operating characteristic curve (ROC) analysis showed that the area under the ROC curve (AUC) and 95% confidence interval for the survival group was 0.640 (0.527-0.754). The cutoff value for MLR was 0.399 at which the sensitivity and specificity were 0.864 and 0.396, respectively. Survival analysis showed that the 90-day survival rate was significantly lower in the high MLR group than corresponding low MLR group (=0.011). Logistic multivariate regression analysis showed that after adjusting for other factors, MLR level was an independent prognostic factor in patients with HBV-ACLF. MLR can be used as a potential prognostic indicator for patients with HBV-ACLF, and its clinical value needs to be verified by large-scale prospective randomized trials.
