Donor-specific antibodies (DSA) form a significant barrier in solid organ transplantation of highly pre-sensitized candidates. Although avoiding transplantation over a positive cross-match test can largely prevent the occurrence of hyperacute antibody-mediated rejection, transplantation of highly pre-sensitized candidates is often complicated by the occurrence of acute and chronic antibody-mediated graft rejection leading to diminished graft function and survival. The pre-existent HLA and/or non-HLA-specific antibodies are without any doubt important contributing factors underlying humoral-mediated graft injury. Furthermore, increasing evidence underlines the association of newly formed de novo DSA after transplantation with poor graft function and survival. There is still a need to further develop desensitizing therapies not only to make transplantation of highly pre-sensitized candidates feasible, but also to reduce the new formation of allo-antibodies. Here, we summarize current views on desensitization therapies and the impact of the presence of DSA on the fate of the kidney graft. [ABSTRACT FROM AUTHOR]
