Although incompatibility is usually viewed as affecting potential recipients of live donors, it is also encountered in instances of directed donation of deceased donors. In these cases, the family or guardian of a deceased donor requests that an organ be assigned to a recipient in the deceased donor wait list. It has been reported (2) that “at least 100 deceased donor transplants each year have occurred through directed donation.”
Although most chains involve only live donors, current proposals (1) consider the initiation of chains with deceased donors. Such approach could maximize the potential of chains, with the eventual return of a live donor kidney to the deceased donor wait list. Ethical and organizational concerns have been raised with respect to the initiation of chains with deceased donors. Furthermore, selecting blood type O donors to initiate chains could disadvantage blood type O wait list recipients.
We believe it would be particularly interesting to develop exchanges (as diagrammed below) initiated with deceased donor kidneys from incompatible directed donations. Rather than denying the donor family and the designated recipient the possibility of a transplant, the organ would be allocated to initiate an exchange. As part of the exchange, the previously incompatible recipient would receive a compatible live donor kidney.
Conclusion: Advantages of this exchange include:
-Transplantation of the designated deceased donor recipient (who would otherwise not be immediately transplanted) with a live donor kidney
-Provides a live donor kidney to the deceased donor wait list
-Potentially 5.8 people or more could benefit from this process (at least 4.8 recipients from a chain plus the otherwise incompatible recipient of the directed deceased donor organ)
-No net loss of deceased donor kidneys
-Likely no O blood type disadvantage
