OBJECTIVETo investigate the prevention and treatment of hepatitis B virus (HBV) reinfection and recurrence after orthotopic liver transplantation (OLT) for HBV related end-stage liver disease.

METHODSThe clinical data of 316 patients undergoing allograft orthotopic liver transplantation who lived more than 6 months and had HBV infection preoperative with complete data from March 2001 to March 2007 at the First Affiliated Hospital of Sun Yat-sen University. According to the HBV prevention strategy, these patients were divided into two groups: group with pure lamivudine (LAM) (n = 106) and group with lamivudine plus intramuscular injection of low dose anti-hepatis B immunoglobulin (HBIG) (n = 210).

RESULTSMean follow-up was 33.6 months. The rate of HBsAg negative conversion 1 week after OLT of the LAM group was 82.1% (87/106), significantly lower than that of LAM + HBIG group [91.0% (191/210), P < 0.05]. The rates of HBV reinfection, HBV recurrence, and YMDD mutation of the lamivudine group was 17.0% (18/106), 11.3% (12/106) and 8.5% (9/106) respectively, all significantly higher than those of LAM + HBIG group [6.2% (13/210), 3.8% (8/210) and 2.4% (5/210) respectively, P < 0.05 respectively]. All patients with HBV reinfection or HBV recurrence were treated with Adefovir, Entecavir or increased dose of HBIG and achieved better curative effect.

CONCLUSIONSThe therapy with high dose of HBIG combining with adefovir or entecavir is better for patients who have HBV reinfection. Patients with HBV recurrence after OLT should be administrated reasonable liver aid, immunity regulation and anti-hepatic fibrosis to obtain better transplant liver histological results and normal transplant liver function.
