DQ molecules are the principal stimulators of<i>de novo</i>donor-specific antibodies in nonsensitized pediatric recipients receiving a first kidney transplant

Abstract excerpt

Data on the different HLA-antibody (Ab) categories in pediatric kidney recipients developing de novo donor-specific Abs (DSA) after transplantation are scarce. We retrospectively evaluated 82 consecutive nonsensitized pediatric recipients of a first kidney graft for de novo HLA Ab occurrence and antigen specificity. At a median follow-up of 6 years, 29% of patients developed de novo DSA, while 45% had de novo...
