Abstract

BACKGROUND: At present, the scarcity of organs is one of the major problems in transplantation. We present our own experience in expanding the acceptance criteria for deceased donors. We aimed to evaluate the potential impact of using hepatitis B virus (HBV) core antibody (anti-HBc)-positive donor grafts on the long-term liver transplantation results.

MATERIAL AND METHODS: We retrospectively analyzed data from 324 consecutive liver transplantation procedures performed in the largest transplant center in Poland, between January 2007 and February 2012. These patients included 36 who had received a liver from anti-HBc-positive donors.

RESULTS: The presence of anti-HBc antibodies in the donor did not have a significant negative impact on the overall 3-year patient or graft survival rates. Among recipients with pre-transplant HBV infection, patients who received an organ from an anti-HBc-positive donor tended to have an improved survival rate compared with patients who received liver transplants from seronegative donors (p=0.080). However, there was a statistically significant reduction in graft survival (p=0.035) in the recipients without serological markers of HBV infection who received liver transplants harvested from anti-HBc-positive donors.

CONCLUSIONS: These results confirm the validity of extending the acceptance criteria to anti-HBc-positive donors, particularly for patients with a prior HBV infection. Despite the increased risk of graft loss, liver transplantation from anti-HBc-positive donors among recipients not infected with HBV may also be considered in appropriate cases.
