Background: Liver transplantation (LT) with grafts from hepatitis B core antibody (HBcAb)-positive donors has been the object of recent studies, suggesting different outcomes depending on the etiology of viral cirrhosis in the recipient.
Methods: From November 2002 to December 2009, we transplanted 124 livers from hepatitis B surface antigen (HBsAg)-negative HBcAb-positive deceased heart-beating donors to adult recipients with viral cirrhosis, classified as: HBsAg positive (group 1; n = 63); hepatitis C virus (HCV) RNA positive (group 2; n = 52); and simultaneously HBsAg and HCV-RNA positive (group 3; n = 9). Immunosuppression included a calcineurin inhibitor, mycophenolate, and steroids (tapered to suspension in 6 months). In all groups, anti-HBV prophylaxis was performed with anti-HBs immunoglobulins and nucleos(t)idic analogues.
Results: The groups were similar regarding donor, recipient, donor-recipient match, transplant procedure, variables, and treatment of acute rejection, except for younger recipient age in group 1 (P = .009), lower recipient body mass index in group 3 (P = .03), and longer cold ischemia time in group 2 (P = .003). Median follow-up for surviving grafts was 63 (range, 16-102) months. No case of recurrent or de novo hepatitis B occurred. The prevalence of histologically proven recurrent HCV hepatitis was similar in groups 2 and 3 (65% vs 78%). Graft survival at 5 years was 86% in group 1, 35% in group 2, and 31% in group 3 (P < .0001 for group 1 vs 2; P < .01 for group 1 vs 3). On multivariate analysis, independent predictors of worse graft survival were HCV infection in the recipient (HR 8.08, 95% CI 3.36-17.97; P < .0001) and MELD at LT ≥25 (HR 3.72, 95% CI 1.12-12.37; P = .032).
Conclusions: The presence of HCV infection in the recipient is the factor which most negatively influenced the outcome of LT using grafts from HBcAb-positive donors. Allocation of such grafts should consider the type of viral cirrhosis among LT candidates.
