Evaluation of five lymphocyte-based scores for prediction of mortality in hepatitis B virus-associated decompensated cirrhosis

Background: Lymphocytes are generally accepted to be a key component of the immune response, and an inadequate immune response is closely associated with disease severity and adverse outcomes in hepatitis B virus (HBV)-infected patients. The present study aimed to determine and compare the prognostic values of five lymphocyte-based scores (monocyte-to-lymphocyte ratio [MLR], mean platelet volume-to-lymphocyte ratio [MPVLR], neutrophil-to-lymphocyte ratio [NLR], red cell distribution width-to-lymphocyte ratio [RLR], and C-reactive protein-tolymphocyte ratio [CLR]) for HBV-associated decompensated cirrhosis (HBV-DC). Methods: Data were extracted from an institutional database. The outcome was 30-day mortality. Receiver operating characteristic curve analyses were conducted, and the resulting area under the curve (AUC) values were used to evaluate the predictive capabilities of the five lymphocyte-based scores for mortality in HBC-DC relative to Model for End-Stage Liver Disease (MELD) score. Results: The study included 273 patients, and the 30-day mortality was 20.9%. Lymphocyte counts were slightly lower in non-survivors than in survivors. The prognostic values of CLR, NLR, MLR, MPVLR, and RLR for mortality in HBV-DC were different. The predictive powers of NLR and MLR were superior to those of the other three scores and similar to that of MELD score. Multivariate analyses identified NLR, MLR, and MELD score as independent prognostic predictors. Conclusion: High NLR and MLR are easily accessible and reliable indicators for predicting 30-day mortality in HBV-DC and have superior prognostic ability compared with other lymphocyte-based scores.

Automated summary

This study compared the prognostic values of five lymphocyte-based scores in HBV-associated decompensated cirrhosis patients and found that the neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte ratio (MLR) had superior prognostic ability for predicting 30-day mortality.
