Background: Although the outcomes of living donor liver transplantation (LDLT) for pediatric acute liver failure (PALF) have improved, patient survival remains lower than in patients with chronic liver disease. We investigated whether the poor outcomes of LDLT for PALF persisted in the contemporary transplant era.
Methods: We analyzed 193 patients who underwent LDLT between December 2000 and December 2020. The outcomes of patients managed in 2000-2010 (era 1) and 2011-2020 (era 2) were compared.
Results: The median age at the time of LDLT was 1.2 years both eras. An unknown etiology was the major cause in both groups. Patients in era 1 were more likely to have surgical complications, including hepatic artery and biliary complications (p = 0.001 and p = 0.013, respectively). The era had no impact on the infection rate after LDLT (cytomegalovirus, Epstein-Barr virus, and sepsis). The mortality rates of patients and grafts in era one were significantly higher (p = 0.03 and p = 0.047, respectively). The 1- and 5-year survival rates were 76.4% and 70.9%, respectively, in era 1, while they were 88.3% and 81.9% in era 2 (p = 0.042). Rejection was the most common cause of graft loss in both groups. In the multivariate analysis, sepsis during the 30 days after LDLT was independently associated with graft loss (p = 0.002).
Conclusions: The survival of patients with PALF has improved in the contemporary transplant era. The early detection and proper management of rejection in patients, while being cautious of sepsis, should be recommended to improve outcomes further.
