Kidney transplantation from hepatitis B (HB)-positive donors to HB negative recipients: anti-HB Core immunoglobulin G became positive in all recipients after the transplantation.

Objective: Hepatitis B surface antigen (HBsAg)-positive donors are not accepted by many transplant centers as a kidney source owing to risk of transmission of hepatitis B; however, some reports show that these donors can be used under a special protocol. Herein, we report our cases of kidney transplantation from HBsAg(+) donors to HbsAg(-) recipients.
Methods: In the years 2010-2012, we transplanted 4 kidneys from 4 HBsAg(+) donors to HBsAg(-) recipients. They were all living related. All antiHBs(-) recipients were vaccinated before transplantation and became HBsAg(-), anti-HB core immunoglobulin G antibody negative [antiHBcIg(-)], and antiHBs(+). Pretransplantation antiHBs titers were targeted to be >100 IU. If lower, hepatitis B Ig was used at the time of transplantation. One patient received hepatitis B Ig at the time of transplantation (owing to titer of 62 IU/L antiHBs). Lamivudine was prescribed for all kidney allograft recipients after transplantation.
Results: Two patients had special induction treatment including rituximab, intravenous immunoglobulin, and plasmapheresis owing to the presence of donor-specific antibody.
Conclusions: All patients became antiHBcIgG(+) at 1-6 months after the transplantation, despite the presence of antiHBs positivity, which might be explained by transmission of hepatitis B virus through the graft.
