BackgroundHLA molecular mismatch (MM) has been shown to be a risk factor for de novo donor-specific antibody (dnDSA) development in solid organ transplantation (SOT). HLA expression differences have also been associated with adverse outcomes in hematopoietic cell transplantation. We sought to study both MM and expression in assessing dnDSA risk. MethodsOne-hundred-and-three HLA-DP-mismatched SOT pairs were retrospectively analysed. MM was computed using amino acids (aa), eplets and, supplementa...
