The presence of HLA-DSAs on the highest rank pregraft serum associates with a significantly decreased graft survival (A), regardless of whether HLA-DSAs were class I or II (B). (C) The occurrence of acute AMR associates with a significantly decreased graft outcome. (D) Even in the absence of acute AMR, patients with preexisting HLA-DSAs have poorer graft survival as compared to patients without preexisting HLA-DSAs. Donor-specific HLA antibodies are detected by SAFB Luminex technique. P values are calculated with the use of the log-rank test.
