Abstract

Background: Presensitization to human leukocyte antigen (HLA) tends to decrease renal graft survival. During the pregnancy, fetal blood is frequently exposed to the maternal circulation possibly inducing maternal immunization to paternal HLA inherited by the fetus. In this way, pregnancy may occasionally present a hazard to renal graft survival. In this study, we compared retrospectively graft survivals according to living related donor-recipient pairs. Materials and methods: From July 1979 to January 2011, 374 patients underwent living related renal transplantation sharing at least one HLA haplotype with their donor. We compared acute rejection and complication rates as well as long-term graft survival according to the donor-recipient paring: child-to-mother, child-to-father, mother-to-child, father-to-child, and one haplotype-matched siblings. All patients received immunosuppressive therapy, consisting of a calcineurin inhibitor, mycophenolate mofetil, or azathioprine and prednisolone. Results: Twenty-one cases (5.6%) were child-to-father paring; 28 (7.5%), child-to-mother; 179 (47.9%), one-haplotype-matched siblings; 46 (12.3%), father-to-child; and 100 (26.7%), mother-to-child paring. Child-to-father pairing displayed the best graft survival; child-to-mother (hazard ratio [HR] = 1.709, P =.662) and one-haplotype-matched siblings (HR = 6.589, P =.062) showed no significant difference. Father-to-child pares experienced poorer outcomes than child-to-father pairs (HR = 11.579, P =.017) and mother-to-child, the poorest graft survival (HR 17.188, P =.005). Conclusion: Pregnancy continues to be a significant source of presensitization in the course of gestation and after parturition. Graft failure can result from an anamnestic reaction subsequent to intrauterine exposure of the mother to HLA of a fetus due to sensitization.
