| Abstract: |
This report summarizes the content of a debate sponsored by eGenesis Bio, organized by the International Xenotransplantation Association (IXA), and attended by more than 150 delegates in the context of the IPITA‐IXA‐CTRMS Joint Congress held in San Diego in October 2023. The debate centered around two important immunological topics relating to xenotransplantation. The first was a debate relating to the statement that "HLA‐sensitized patients are at higher risk for rejecting a pig xenograft." Stuart Knechtle provided evidence to support this statement and Massimo Mangiola opposed it. Before the debate, a majority (>80%) of the audience agreed with this statement. After listening to the debate, this percentage was reduced to approximately 60%. The second debated statement was "Recipients of pig xenografts who develop anti‐pig antibodies are at higher risk for rejecting a subsequent allograft." This was proposed by A. Joseph Tector and opposed by Léo H. Bühler. Before the debate, once again a majority of the audience (approximately 60%) believed that prior sensitization to a pig xenograft would be detrimental to the survival of a subsequent allograft. However, after listening to the debate, only about 40% believed this statement to be correct. The topics discussed remain complex and answers are not yet conclusive. However, the present evidence suggests that allosensitization may prove detrimental to subsequent xenotransplantation, whilst sensitization to pig antigens may not be detrimental to subsequent allotransplantation.
