The impact of cytomegalovirus serology for 7-year graft survival in cadaveric kidney transplantation - The Newcastle experience

Abstract

To analyse the contribution of cytomegalovirus (CMV) serology to long-term graft survival in cadaveric kidney transplantation, 404 transplants from a single centre were divided into four subgroups with respect to the combination of donor and recipient CMV antibody status. Graft survival was estimated according to Kaplan-Meier for 1, 3, 5 and 7 years post-transplantation. The single-centre results confirm a negative impact of CMV-positive donor organs for initial graft survival in CMV-negative recipients within the first 3 years after transplantation. However, when 5- and 7-year long-term graft survival was studied, Donor +/Recipient - pairs showed a favourable long-term result, whilst D +/R - pairs had surprisingly a poorer outcome. Therefore, the concept of avoiding transplantation in the D +/R + CMV serology group should be ignored whereas attempts could be made to improve the poor long-term outcome of D +/R + pairs or to reduce its size by organ allocation. © Springer-Verlag 2000.
