OBJECTIVES: Factors prognostic of survival in liver transplant (LT) recipients with hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF) remain unclear. This study evaluated risk factors for survival in LT recipients with HBV-ACLF and determined the scoring system optimal for assessing patient prognosis.
METHODS: This retrospective study included 323 HBV-ACLF related patients undergoing LT, including 112, 146, and 65 patients with HBV-ACLF grades 1, 2, and 3, respectively. Overall survival (OS) was estimated by the Kaplan-Meier method, and factors associated with survival were analysed by multivariate Cox proportional hazards models. Pretransplant prognostic scoring systems were compared by receiver operating characteristic (ROC) curve analysis.
RESULTS: The one-year survival rate was significantly lower in HBV-ACLF grade 3 (80.0%) than in grades 1 (93.8%) and 2 (91.8%) recipients (p=0.0063). Cox multivariate analysis showed that age >53 years (hazard ratio (HR) 3.731; 95% confidence interval (CI) 1.640-8.407), WBC count >8.6 × 109/L (HR 4.544; 95% CI 1.140-18.107), HBV-ACLF 3 (HR 2.729; 95% CI 1.050-7.096), and cold ischaemia time >8.5 hours (HR 2.867; 95% CI, 1.38-5.921) were independently prognostic of 1-year survival. Comparisons of pretransplant scoring systems showed that chronic liver failure-consortium ACLF score (CLIF-C ACLFs) was superior to COSSH-ACLF, MELD-Na, and MELD scores in predicting 1-year OS in these patients.
CONCLUSIONS: Age >53 years, WBC counts >8.6 × 109/L, HBV-ACLF grade 3, and cold ischaemia time >8.5 hours are independently prognostic of OS in LT recipients with HBV-ACLF. CLIF-C ACLFs is superior to other scoring methods in predicting 1-year OS in these patients.
