ABO-incompatible kidney transplantation

Abstract

INTRODUCTION: Kidney transplantation is the optimal treatment for many patients with end-stage renal disease (ESRD). Due to shortage of donor kidneys in Denmark, there is a need to expand the possibilities for donation. At the Odense University Hospital (OUH), we have introduced ABO-incompatible kidney transplantation. We used antigenspecific immunoadsorptions to remove blood group antibodies and anti-CD20 antibody (rituximab) to inhibit the antibody production. The aim of introducing the ABOincompatible kidney transplantation at the OUH was to increase the rate of living donor kidney transplantation without increasing rejection or mortality rates. MATERIAL AND METHODS: Retrospective evaluation. Eleven patients received ABO-incompatible kidney transplantation. The patients were followed for 3-26 months. RESULTS: One patient had an antibody-mediated rejection, one patient suffered T-cell-mediated rejection, and one patient died of myocardial infarction with a functioning graft on the third post-operative day. Both rejections were treated effectively. Among the patients, the average serum creatinine level was 128 micromol/l. CONCLUSION: The rejection and mortality rates for ABO-incompatible kidney transplantation at the OUH are similar to the results from ABO-compatible kidney transplantations performed at the OUH and at other hospitals.
