Recent reports have suggested an association of anti-DP antibodies with allograft rejection and graft loss, in both primary kidney transplant recipients and in re-grafts [1–3]. However, in most cases, it is difficult to separate the effects of anti-HLA-DP antibodies from other anti-HLA class I and class II antibodies. Among non-conserved haplotypes, HLA-DP allele mismatches occur despite matching for HLA class I and class II loci, because of the lack of linkage disequilibrium between DP and other HLA loci [4]
