The aim of this study was to analyze the incidence and risk factors of de novo HBV infection in pediatric patients receiving living donor liver transplants (LDLT) from HBcAb‐positive donors, and to explore its treatment strategies. The data of 101 pediatric recipients receiving LDLT in Tianjin First Central Hospital between September 2006 and December 2012 were retrospectively analyzed. The HBV markers were regularly tested before and after the surgery, including HBsAb, HBsAg, HBeAg, HBeAb, and HBcAb. The median follow‐up period was 25.6 months, during which eight cases (7.92%) were diagnosed with de novo HBV infection. Forty‐four (43.6%) of the children received HBcAb‐positive allografts. The rate of de novo HBV in the children that received HBcAb+ livers vs those received HBcAb? livers was 15.9% (7/44) vs 1.7% (1/57) (P=.037). The rates of de novo HBV in the children who received HBcAb‐positive allografts were significantly less than in those that received preventative therapy with HBIG and lamivudine treatment (2/31, 6.4%) vs those that did not (5/13, 38.5%) (P<.01). HBcAb‐positive liver donors are strongly associated with de novo HBV in HBsAg‐negative pediatric patients receiving LDLT. However, the incidence of de novo HBV infection is significantly less with the use of prophylactic treatment strategies. |
