Liver transplantation for Hepatitis-B-associated liver disease - Three decades of experience

Background Hepatitis B (HBV)-associated end-stage liver disease used to be a relevant indication for liver transplantation (LT). After transplantation, HBV-reinfection remains a serious issue. Different strategies to prevent HBV-reinfection range from the single application of immunoglobulins (HBIG), to the use of modern nucleoside/nucleotide analogues (NUC) in combination with HBIG, followed by HBIG-discontinuation. The aim of this analysis was to compare different strategies and to sum up the results of 30 years at a high-volume transplant center and deliver additional information on the histopathological level. Methods Data of 372 liver transplantations performed for the HBV-induced liver disease in 352 patients were extracted from a prospectively organized database. HBV-reinfection was determined in the entire cohort, according to the mode of HBV-prophylaxis. Differences in survival rates were analyzed in patients with successful prophylaxis, untreated and controlled HBV-reinfection. Histopathological results were obtained from protocol biopsies in 151 patients. Results HBV-reinfection was significantly associated with the type of prophylaxis, presence of HBs-Antigen at the moment of LT, transplant year and influencing the overall survival before 2005. After the introduction of modern NUCs, HBV-reinfection stopped to impact HBV-associated transplant loss and survival. Controlled HBV-infection prevents from HBV-associated transplant hepatitis and fibrosis development. The role of HBIG declines in favor of NUCs. Conclusions Uncontrolled HBV-reinfection does not occur any more. Even in the presence of Hbs-antigen, transplant fibrosis does not develop. The most reliable mode to prevent HBV-recurrence remains the combination of NUCs with a high genetic barrier and HBIG. However, HBIG can safely be discontinued after LT.
