Liver transplantation for autoimmune hepatitis: Pre-transplant does not predict the early post-transplant outcome

Abstract

Background and Aims: Autoimmune hepatitis (AIH) is a rare indication (<5%) for liver transplantation (LT). The aim of this study was to describe the early outcome after LT for AIH. Methods: A multicenter retrospective nationwide study including all patients aged ≥16 transplanted for AIH in France was conducted. Occurrences of biliary and vascular complications, rejection, sepsis, retransplantation and death were collected during the first year after LT. Results: A total of 344 patients (78.8% of women, 17.0% of (sub)fulminant hepatitis and 19.2% of chronic liver diseases transplanted in the context of acute-on-chronic liver failure [ACLF]) were included, with a median age at LT of 43.6 years. Acute rejection, sepsis, biliary and vascular complications occurred in respectively 23.5%, 44.2%, 25.3% and 17.4% of patients during the first year after LT. One-year graft and patient survivals were 84.3% and 88.0% respectively. The main cause of early death was sepsis. Pre-LT immunosuppression was not associated with an increased risk for early infections or surgical complications. Significant risk factors for septic events were LT in the context of (sub)fulminant hepatitis or ACLF, acute kidney injury at the time of LT (AKI) and occurrence of biliary complications after LT. AKI was the only independent factor associated with graft (HR = 2.5; 95% CI: 1.1–5.4; p =.02) and patient survivals (HR = 2.6; 95% CI: 1.0–6.5; p =.04). Conclusion: Early prognosis is good after LT for AIH and is not impacted by pre-LT immunosuppression but by the presence of AKI at the time of LT.
