Outcomes of pediatric liver transplantation for progressive familial intrahepatic cholestasis

Abstract

AbstractBackgroundProgressive familial intrahepatic cholestasis (PFIC) is a heterogenous group of inherited hepatocellular disorders and the clinical aspects, role of liver transplantation (LT), and its outcomes remain largely unelucidated. We present our data of LT for each type of PFIC and compare their early, and long‐term outcomes, highlighting their individual differences and management strategies.MethodsProspectively collected data over a decade (2011–2022) of children with PFIC who underwent LT was analyzed. The groups (PFIC 1–4) were compared with regard to early and long‐term outcomes including attainment of catch‐up growth.ResultsOf 60 children with PFIC who underwent LT, 13, 11, 31 & 5 were of PFIC 1, 2, 3 & 4, respectively. There were no significant differences in gender, PELD scores, BMI, type of grafts, cold and warm ischemia times, intraoperative blood loss, and morbidity among the groups. Post‐LT chronic diarrhea was observed in 6 (46.1%) children with PFIC‐I, and of them, 3 (23%) developed graft steatohepatitis. Three of these children underwent total internal biliary diversion (TIBD) and on 1‐year follow‐up, their graft steatosis resolved and they attained catch‐up growth. Catch‐up growth was significantly poorer in the PFIC1 group (44.4% vs. 88%, 90%, 100% p < .001). Overall 1‐ and 5‐year patient survival of the four PFIC groups (1–4) were 69.2%, 81.8%, 96.8%, 100% & 69.2%, 81.8%, 96.8%, 100%, respectively.ConclusionOurs is the largest to‐date series of LT for PFIC illustrating their short‐ and long‐term outcomes. While the results for the whole cohort were excellent, those after LT for PFIC1 was relatively poorer as reflected by catch‐up growth, graft steatosis, and post‐LT diarrhea, which can be optimized by the addition of TIBD during LT.
