This study investigated the occurrence and possible causes of neurological impairment (NI) in children with acute liver failure (ALF) following liver transplantation (LT). The study found that NI in children following LT was not uncommon, and some cases of NI had unknown causes.
Background Although overall survival of ALF has improved, neurological restoration after recovery from ALF may not always be satisfactory. The purpose of this study was to investigate the occurrence and possible causes of NI in children with ALF following LT. Methods We retrospectively examined all children younger than 16 years old with ALF who subsequently underwent LT at our center between January 2005 and December 2016. NI was assessed in December 2016 using the six-point Pediatric Cerebral Performance Category score and was defined as any increase in the score. Results There were 62 children with median age 10 months (quartile range 5-34). The etiology of ALF was indeterminate in 47 children (75.8%). The median duration from admission to LT was 5.5 days (quartile range 4-7), and 96.8% (60/62) received living donor LT. The overall survival was 83.9% (52/62) in a median follow-up period of 4.2 years. Mild-to-moderate NI was observed in 23.1% (12/52) of the survivors. Possible causes of NI were underlying systemic disease (n = 3), perioperative brain lesion (n = 2), and unclassified (n = 7). All seven patients with unclassified NI were less than 12 months old. The unclassified NI causes were presumed to be ALF, its perioperative care, and the vulnerable infant brain. Conclusions NI in children with ALF following LT was not rare and should be prevented. Further investigations are required to clarify the characteristics of the patients with unclassified NI.
