Highly HLA-sensitized (HS) patients have an increased risk for the development of donor-specific antibodies (DSA) and antibody-mediated rejection (AMR) posttransplant. Here, we examined the risk for AMR in HS patients transplanted after desensitization (DES) who were DSA+ versus DSA- at transplant. We also examined the incidence and clinical impact of de novo DSAs (dnDSAs) and compared with dnDSA- patients.
