title: The impact of donor and recipient hepatitis B surface antigen status on liver disease and survival in renal transplant recipients.
abstract: Ninety-eight renal transplant recipients who had been followed for 1-6.5 years (median 3.2 years) were reviewed to determine the effect of donor and recipient hepatitis B surface antigen status on the incidence of hepatitis and on patient survival. The cumulative risk of developing hepatitis posttransplant was significantly higher in hepatitis B surface antigen-positive versus hepatitis B surface antigen-negative patients (P = 0.001). Nine (60%) of 15 patients who were hepatitis B surface antigen-positive prior to transplantation, 3 (75%) of 4 patients who became hepatitis B surface antigen-positive after transplantation, and 17 (22%) of 79 patients who were persistently hepatitis B surface antigen-negative developed hepatitis posttransplant. Five hepatitis B surface antigen-negative patients received allografts from hepatitis B surface antigen-positive donors. None of the five, including one who was initially seronegative, became hepatitis B surface antigen-positive posttransplant. Of the four patients who became HBsAg-positive posttransplant, three received kidneys from donors of unknown HBsAg status in China, while one was transplanted with a kidney from a HBsAg-negative donor. In summary, we found that the risk of developing hepatitis after renal transplantation was significantly higher in hepatitis B surface antigen-positive patients. However, both patient and graft survival were similar in hepatitis B surface antigen-positive and hepatitis B surface antigen-negative patients. The transplantation of kidneys from HBsAg-positive donors to HBsAg-negative patients did not result in clinically significant hepatitis or chronic HBsAg carriage. De novo hepatitis B infection may arise from sources other than the kidney itself.
