Coronavirus disease 2019 (COVID-19) is an ongoing pandemic. The occurrence of acute liver injury (ALI) has been reported in liver transplant (LT) recipients; however, the findings on children remain controversial. This is the first extensive, worldwide report on the impact of COVID-19 on pediatric LT recipients. Our online survey reported 110 pediatric LT recipients with severe acute respiratory syndrome coronavirus 2 infection. Of these, 37 were symptomatic and 20 out of them (54%) had complicated COVID-19, which included ALI and acute liver graft rejection. No mortality was reported. Pediatric LT recipients who had undergone transplantation less than 6 months before contracting COVID-19 had a greater number of hospital admissions and a higher ALI frequency (P = 0.013 and P = 0.033, respectively) than those who had undergone transplantation more than 6 months prior. Our study found that COVID-19 cases among pediatric LT recipients demonstrated a high complication rate. We propose that these patients must be followed up strictly.
