ABSTRACT
Objective To investigate the value of total bilirubin rebound rate (TBRR), total bilirubin clearance rate (TBCR), and TBCR after 1 week of treatment (ΔTBCR) in evaluating the short-term prognosis of patients with severe drug-induced liver injury (DILI) after artificial liver support therapy. Methods A retrospective analysis was performed for 203 patients with severe DILI who received artificial liver support therapy in Tianjin Third Central Hospital from September 2013 to December 2021, and general information, biochemical parameters, and clinical classification were collected. The patients were divided into improved group and unhealed group according to the prognosis at discharge, and Model for End-Stage Liver Disease (MELD) score, TBRR, TBCR, and ΔTBCR were calculated. The independent samples t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups. The receiver operating characteristic (ROC) curve was plotted to investigate the value of assessment indices in predicting the prognosis of patients, and the Kaplan-Meier method was used to investigate the difference in the length of hospital stay in the context of different assessment indices. Results Compared with the unhealed group, the improved group had significantly lower age ( t =-2.762, P < 0.05), white blood cell count ( Z =-3.184, P < 0.05), total bilirubin ( t =-2.809, P < 0.05), conjugated bilirubin ( t =-2.739, P < 0.05), international normalized ratio ( Z =-2.357, P < 0.05), MELD score ( t =-3.090, P < 0.05), and TBRR ( t =-4.749, P < 0.05), as well as significantly higher albumin ( t =2.198, P < 0.05), prothrombin time activity ( t =2.018, P < 0.05), TBCR ( t =2.166, P < 0.05), and ΔTBCR ( t =9.549, P < 0.05). MELD score, TBRR, TBCR, and ΔTBCR had an area under the ROC curve (AUC) of 0.656, 0.727, 0.611, and 0.879, respectively, and ΔTBCR had a better predictive value than TBRR ( Z =3.169, P =0.001 5). The optimal cut-off value was 22.5% for TBRR (with a sensitivity of 94.6% and a specificity of 45.2%) and 27.4% for ΔTBCR (with a sensitivity of 77.7% and a specificity of 86.5%). ΔTBCR showed a good predictive value in different clinicopathological types, with extremely high sensitivity (91.4%) and specificity (100.0%) in evaluating the treatment outcome of patients with mixed-type DILI after artificial liver support therapy. Conclusion TBRR and ΔTBCR have a higher value than MELD score in evaluating the short-term prognosis of patients with severe DILI after artificial liver support therapy, among which ΔTBCR has a higher predictive value.
