Clinical analysis of liver transplantation in autoimmune liver diseases

Background: Autoimmune liver diseases(ALDs) consist of autoimmune hepatitis(AIH), primary biliary cirrhosis(PBC), primary sclerosing cholangitis(PSC), Ig G4-associated cholangitis and overlap syndromes.Patients with these diseases may gradually progress to end-stage liver diseases and need liver transplantation. The present study aimed to explore the prognosis of patients with ALDs after liver transplantation.Methods: The clinical data of 80 patients with ALD(24 cases of AIH, 35 of PBC, 15 of PSC and 6 of AIHPBC overlap syndromes) who underwent liver transplantation in Renji Hospital, Shanghai Jiao Tong University School of Medicine from June 2004 to September 2016 were collected retrospectively. The causes of death were analyzed and the postoperative cumulative survival rate was estimated by the Kaplan–Meier method. Recurrence and other complications were also analyzed.Results: Of the 80 patients, 18 were males and 62 were females. The average age was 50.5 years and the average Model for End-stage Liver Disease(MELD) score was 14.1. After a median follow-up of 19.8 months, 8 patients died. The 1-, 3-and 5-year cumulative survival rates were all 89.0%. Three cases of recurrent ALDs were diagnosed(3.8%) but they were not totally consistent with primary diseases. Biliary tract complication occurred in 10 patients(12.5%). The new onset of tumor was observed in 1 patient(1.3%). De novo HBV/CMV/EBV infection was found in 3, 8 and 3 patients, respectively.Conclusion: Liver transplantation is an effective and safe treatment for end-stage ALD.
