Abstract:
Objective:To investigate the diagnostic and prognostic value of D-dimer level in patients with hepatitis B-related acute-on-chronic liver failure (HBV-ACLF).Methods:A total of 142 cases diagnosed with ACLF were randomly selected as research objects in the open cohort using the Chinese Group on the Study of Severe Hepatitis B-ACLF (COSSH-ACLF). Plasma D-dimer levels were compared between patients with ACLF and non-ACLF and patients with different ACLF grades. Survival and death group D-dimer levels were compared with the end points of 28 days and 90 days, respectively. The correlation between D-dimer and other laboratory indicators and prognostic scores were investigated. Area under receiver operating characteristic curve (AUROC) was used to evaluate the D-dimer value for predicting the prognosis of ACLF patients. 125 external ACLF cases were used for validation. A Student t test or Mann-Whitney U test was used to compare continuous measurement data between two groups. Kruskal-Wallis test was used to compare continuous measurement data between multiple groups.Results:Plasma D-dimer levels in the ACLF [2 588.5 (1 142.8, 5 472.8) μg/L] ] and non-ACLF group [1 385.5 (612.0, 3 840.3) μg/L] had a significant difference ( P<0.001). ACLF-3 patients had significantly higher D-dimer levels than ACLF-1/2 patients (ACLF-3 vs. ACLF-1, P<0.001; ACLF-3 vs. ACLF-2, P<0.05). Patients who died at 28/90 days had significantly higher D-dimer levels than those whom survived ( P<0.001). There was a significant positive correlation between D-dimer level with prothrombin time (PT), international normalized ratio (INR), high-density lipoprotein C, as well as various prognostic scores (COSSH-ACLFs, CLIF-C ACLFs, CLIF-OFs, MELDs). AUROC of D-dimer in predicting the prognosis of ACLF patients at 28 days and 90 days was 0.751 (95% CI: 0.649-0.852) and 0.787 (95% CI: 0.695-0.878), respectively, which did not differ significantly compared with the predictive ability of other scores ( P<0.05), and similar results were confirmed by an external validation group of 125 cases. Conclusion:D-dimer level is significantly higher in patients with ACLF, so it is an independent predictor of prognosis at 28 and 90 days.
