Favorable Outcomes of Elderly ABO-Incompatible Kidney Transplantation-Pilot Single Center Experience.

BACKGROUND: The growth in the end-stage kidney disease (ESKD) population has been predominantly in the older adult population. In Japan, ABO-incompatible kidney transplantation has become an acceptable treatment option. However, few studies have been conducted on elderly ABO-incompatible kidney transplantation.

PATIENTS AND METHODS: Seventeen patients aged 60 years and older who received their grafts from ABO-incompatible living donors at our institution between December 2006 and September 2016 were enrolled in this study, and the outcome of these recipients was evaluated.

RESULTS: All 17 patients underwent successful kidney transplantation. Both overall patient and graft survival rates were 100, 100, and 83.3% at posttransplant 1, 3, and 5 years respectively. Six of the 17 patients (35.3%) had an episode of biopsy-proven acute cellular rejection. Two patients who developed steroid- and deoxyspergualin-resistant acute rejection required anti-human thymocyte immunoglobulin.

CONCLUSION: ABO-incompatible kidney transplantation may be an effective radical renal replacement therapy for elderly patients with ESKD, although it could be a high-risk procedure.
