Objective To analyze the HBV recurrence and summarize the experiences in treatment of HBV recurrence after liver transplantation for HBV related liver diseases.Method A total of 650 patients subject to liver transplantation for HBV related liver diseases from September 2002 to February 2007 were included,and the clinical data were retrospectively analyzed.Result Twenty-five (3.85％) of 650 patients experienced HBV recurrence.All liver functions recovered to normal after nucleoside or nucleotide analogs treatment.Two cases lost to follow-up,2 cases were died of tumor recurrence,and 1 case died of tumor recurrence after re-transplantation.Eleven cases were positive for serum HBsAg,and HBV DNA was converted to undetectable levels in 10 cases.One case developed to decompensated liver cirrhosis,and HBsAg was negative after re-transplantation.In 7 cases,after nucleos(t)ide analogs treatment,HBsAg titer was decreased gradually to a lower level,and continuous intravenous drip of large doses of HBIG for 3 to 5 days achieved anti-HBs seroconversion.Conclusion Nucleos(t) ide analogs can effectively suppress viral replication of HBV recurrence after liver transplantation.When the HBsAg titer is decreased to a lower level,large doses of HBIG can achieve anti-HBs seroconversion.

Objective: The aim of this study was to summarize and analyze the clinical features and characteristics of de novo HBV infection after liver transplantation in non-HBV-related liver disease. Methods: We retrospectively analyzed the clinical data of 13 patients with new HBV infection in 376 cases of liver transplantation patients with non-HBV related liver diseases from April 2002 to December 2013 in our hospital. Results: Among 376 patients with non-HBV-related liver disease after liver transplantation, 13 patients developed new HBV infection, and the rate of new HBV infection was 3.46%. Of the 13 cases, 5 were males and 8 were females. The follow-up time was 14.7 -128.7 months, and the average time from surgery to new HBV infection was 19.06 months. The primary diseases were as follows: 5 cases of primary biliary cholangitis, 3 cases of alcoholic liver disease, 2 cases of drug-induced liver damage, 1 cases of post-hepatitis C cirrhosis, congenital biliary atresia and congenital liver fibrosis. All patients were positive for HBsAg, HBeAg, anti-HBc, 11 were positive for HBV DNA, and 2 were negative for HBV DNA. 6 cases had abnormal liver function and 7 cases had normal liver function. All patients were treated with antiviral therapy with nucleoside (acid) analogues. HBsAg was negative in 6 patients; HBsAg remained positive in 7 cases, including HBsAg, HBeAg, anti-HBc positive in 6 cases, HBsAg, anti-HBe, anti- HBc was positive in 1 case, HBV DNA was still positive in 1 patient, and HBV DNA was negative in 6 patients; liver function was normal in all patients. Conclusion Non-HBV- related liver transplantation are high-risk group of new HBV infection, with the highest incidence of autoimmune liver disease. It is speculated that it may be related to the long-term use of hormones after the transplantation. The prognosis of newly diagnosed HBV infection after liver transplantation is fine as long as it can be found and treated early.
