Introduction: Due to the severe shortage of deceased donors in Japan, ABO-incompatible living donor kidney transplantation has been performed since the late 1980s. Excellent long-term outcomes have been achieved; the rates of graft survival among these patients are currently similar to those of recipients of ABO-compatible grafts. Our single-center experience describing the immunosuppressive protocols, complications, and grafts survivals is documented in this study.
Patients and methods: Among 123 patients with end-stage renal disease who underwent living donor kidney transplantation between January 1999 and December 2010, 25 cases were ABO-incompatible grafts. All of these patients were followed until August 2011. Analyzing these patients, we focused on their immunosuppressive protocols, complications, and graft survivals.
Results: Patient and graft survival rates were 100%. One patient experienced antibody-mediated rejection and an intractable acute cellular rejection episode, 1 patient an antibody-mediated rejection, and 6 patients had acute cellular rejection episodes. However, there were no severe complications.
Conclusion: Although ABO-incompatible kidney transplantation is a high-risk procedure, a short-term graft survival rate of 100% may be expected due to recent significant improvements in desensitization and recipient management.
