Background: Cirrhotic patients with hemorrhagic ascites have significant morbidity and mortality. This study aims to determine the relationship between D-dimer values and hemorrhagic ascites in cirrhotic patients and analyze its predictive value.
Methods: This retrospective study screened 572 consecutive cirrhotic patients with ascites and hemorrhagic ascites (defined as red blood cells (RBC) in ascitic fluid ≥ 10,000/µL) during a 72-month period. The overall patient survival rate was measured by Kaplan-Meier analysis method. The relationship between D-dimer and hemorrhagic ascites was also examined. A multivariate Cox proportional hazard analysis was performed to assess the indepen-dent risk factors related to mortality.
Results: Both control group and hemorrhagic ascites patients had obvious hepatic dysfunction as determined by Model for End-Stage Liver Disease (MELD) scores of 6.37 ± 1.05 and 11.82 ± 2.86, respectively (p < 0.001). There was a higher prevalence of patients with significant ascites in those with spontaneous hemorrhagic ascites than in the control group (p = 0.003). There were significant differences in D-dimer levels between both groups (9.44 ± 5.11 vs. 26.83 ± 5.35, p < 0.001). Hemorrhagic ascites was significantly and positively correlated with D-dimer levels (r = 0.692, p < 0.0001). The area under the receiver operating characteristic (ROC) curve was 0.9838. Using Cox proportional hazard model for multivariate prognostic analysis, MELD, D-dimer and presence of spontaneous hemorrhagic ascites were independent predictors of 3-year mortality.
Conclusions: Patients with hemorrhagic ascites had a significantly higher MELD score, D-dimer, and mortality than patients with ascites alone. D-dimer was associated with the appearance of hemorrhagic ascites and was found to be a marker of advanced liver disease and poor outcomes.
