Purpose: This study evaluated the effects of organ sharing on the allocation of kidneys from cadaveric donors to uremic patients from National Cheng Kung University Hospital (CKUH) and National Taiwan University Hospital (NTUH) who were waiting for kidney transplantation. Methods: Standard complement-dependent microcytotoxicity assays were used. Human leukocyte antigen (HLA),A,B,C typing was performed on nylon-wool-enriched T lymphocytes. HLA-DR typing was performed on either nylon-wool-separated B cells or Dynabeads. Isolation of class II-positive cells was performed with commercial typing trays. Results: Organs were allocated from a total of 88 cadaveric donors to 320 patients treated at CKUH and 179 patients treated at NTUH. Cadaveric kidneys could be allocated with an A,B,DR mismatch to 6.9% of CKUH patients and to 4.7% of NTUH patients. When CKUH and NTUH patients were pooled, the total number of kidneys that could be allocated with 0-A,B,DR mismatch increased to 13.3% (p < 0.004). However, when allocation was assessed using 10,000 potential bone marrow donors instead of the 88 cadaveric donors, kidneys could have been allocated with 0-A,B,DR mismatch to 12% (p = 0.64) of patients. No significant benefit was found when allocation estimates from the 10,000 potential bone marrow donors were compared with those for the 88 cadaveric donors. Use of epitope matching resulted in a 0- A,B cross-reactive epitope group, and a 0-DR mismatch allocation rate of 36.4% in CKUH patients and 31.8% in NTUH patients. This rate increased to 54.6% (p< 0.001) when the patients from these hospitals were pooled. Conclusion: The results of this study demonstrate that the pooling of patients among regional transplant centers in Taiwan can significantly enhance the benefits of an organ donation program through better HLA matching.
