Clinical Trial Summary

Kidney transplantation is the preferred treatment for end-stage renal disease. Alongside limited availability of donors, rejection and premature graft loss are main barriers to kidney transplantation. Donor-specific antibodies pre-transplantation may arise due to to prior solid organ transplantation, pregnancy or blood transfusions. Their presence is considered a risk of graft failure. The impact of DSA is differently reported in literature, also according to the technique by which DSA have been measured. Techniques such as the complement-dependent cytotoxicity crossmatch, the immunofluorescence crossmatch and the Luminex Single Antigen Bead have different sensitivities for detecting DSA.

Historically, our kidney transplant program has been advocating living donor transplantation and as a result the majority of transplantations are with a living donor. In this context and in the absence of a compatible living donor, pretransplant DSA have not been considered an absolute contra-indication for transplantation. The aim of the current study is to determine the effect of DSAs on rejection and death-censored graft survival in living donor kidney transplantation.

Participants are adults who underwent a living donor kidney transplantation between 2010 and 2019 in the presence of DSA. Control subjects are both immunized and non-immunized kidney transplant recipients in the same period.

This is a retrospective, case control study. Death-censored graft survival is analyzed for all patients and compared by presence of DSA and other predicting variables, such as immunization level, age, sex and HLA mismatches. Furthermore, biopsy proven rejection, patient survival, kidney function, length of hospital stay and proteinuria are analyzed.

Also, a predefined subgroup analysis is performed in the DSA positive patients. These are compared according to amount, strength and HLA-class of DSAs.
