Abstract
Hepatitis B virus-related acute-on-chronic liver failure remains a life-threatening syndrome, and transplant is the definitive treatment. Early allograft dysfunction is a postoperative complication and affects morbidity and mortality. We studied the risk factors associated with early allograft dysfunction in livertransplantrecipients with hepatitis B virus-related acute-on-chronic liver failure. This single-center retrospective study of early allograft dysfunction is based on data from January 2015 to June 2020 for 323 recipients with hepatitis B virus-related acute-on-chronic liver failure and 445 with only hepatitis B virus infection (control group). Data that correlated with early allograft dysfunction and outcome were analyzed. Incidence of early allograft dysfunction in patients with hepatitis B virus-related acute-on-chronic liver failure was significantly higher versus the control group (39.3% vs 21.1%; P < .001). Transplant recipients with hepatitis B virus-related acute-onchronic liver failure who developed early allograft dysfunction had lower 90-day, 180-day, and 360-day patient survival rates versus patients with no early allograft dysfunction (89.0% vs 98.0%, 82.7% vs 97.5%, and 80.3% vs 96.4%, respectively; P < .001). Pretransplant kidney failure (odds ratio, 2.644; 95% CI, 1.019-6.864; P = .046), pretransplant coagulation failure (odds ratio, 2.162; 95% CI, 1.291-3.621; P = .003), and operative time (odds ratio, 1.005; 95% CI, 1.002-1.008; P = .003) were independent risk factors for early allograft dysfunction in liver transplant recipients with hepatitis B virus-related acute-onchronic liver failure. There was a synergistic effect of early allograft dysfunction and preoperative kidney/coagulation failure on survival rates of liver transplant recipients with hepatitis B virus-related acute-on-chronic liver failure. Preoperative kidney/coagulation failure and operative time were independent risk factors of early allograft dysfunction in deceased donor liver transplant recipients with hepatitis B virus-related acute-on-chronic liver failure. The combination of early allograft dysfunction and preoperative kidney/coagulation failure was significantly associated with lower survival of these recipients.
