Outline of Final Research Achievements

In this study, the number of mismatch eplets alone did not have a clear impact on the prognosis of transplanted kidneys. The reasons for this may be that the number of patients was not sufficient, the observation period was not long enough, and the immunosuppressive protocols have changed over the years, so the comparison under the same conditions was not possible. In addition, in the Japanese population, which has relatively low HLA diversity, there is little diversity in MM eplet numbers, and it may be difficult to show differences based on the mismatch eplets alone.
In the future, we will conduct risk stratification of CAMR based on the risk assessment of MM eplet numbers reported by various authors, use different immunosuppressive protocols accordingly, and prepare a study to launch a prospective study.

Academic Significance and Societal Importance of the Research Achievements

さらなる研究により、HLA構造解析に依拠した慢性拒絶反応リスク階層化により、患者個人個人の適正な免疫抑制プロトコールを適用し、副作用なく長期の生着を目指すことが可能になると思われる。
