Hepatitis B Antigen Kidney Graft Into Protective Level Hepatitis B Antibody Recipients

January 22, 2014 updated by: Wiwat Chancharoenthana, Chulalongkorn University

The Outcomes of Kidney Transplantation Between Recipients Receiving Graft From Donors With Positive and Negative HBsAg

To determine the safety of using kidney organ from hepatitis B surface antigen positive donor, the author conducted the single-center, prospective study of the use of these kidneys for recipients who have protective level of hepatitis B surface antibodies.

Detailed Description

The kidney transplant registry was conducted in KCMH since the year of 2000 until the present.

The inclusion criterion was:

  • All kidney allograft recipients who received at least one month after transplantation.
  • All kidney recipients who already had the protective antibody against hepatitis B virus infection defined by anti-HBs titer above 100 mIU/mL at pre-transplantation period.

The exclusion criterion was:

  • The recipients with positive hepatitis C virus antibody.
  • The recipients who had received a previous or simultaneous non-kidney solid organ transplant.
  • The recipients those lost to follow-up.

Study group:

  • The recipients who received kidney allograft from the HBsAg(+) donor.

Control group:

  • The recipients who received kidney allograft from the HBsAg(-) donor.

According to the Thai Red Cross National Organ Donation and our institute's policy, the HBsAg(+) kidney allografts were distributed to only and informed consent.

Data collection:

  • Baseline characteristic data e.g. donor and recipient age, donor and recipient gender, HLA, PRA, anti-HBs titer, immunity against HBV status (both natural and vaccinated),immunosuppressive regimens were collected.
  • The recipients were prospective followed up at month 3, 6, 9, 12, 18, 24, 36, 48, 60, 72, 84, 96, 108, 120.
  • Clinical data including jaundice, hepatitis, graft rejection were collected
  • Laboratory data of HBsAg, anti-HBc, HBV DNA, SGOT, SGOT, eGFR were collected.
  • Pathological data of allograft biopsy at month 12 and 24 were retrieved.

Outcomes:

  • Primary outcome: hepatitis B transmission rate.
  • Secondary outcome: graft survival, patient survival.
