Acute Rejection, Kidney Allograft Function, and Graft Survival in Patients with Circulating Pre-Transplant IgG Antibodies Directed Against Donor HLA-A, -B, or -C Locus Determined Antigens.

Acute Rejection, Kidney Allograft Function, and Graft Survival in Patients with Circulating Pre-Transplant IgG Antibodies Directed Against Donor HLA-A, -B, or -C Locus Determined Antigens. Clin Transpl. 2016;32:83-91 Authors: Abuhelaiqa E, Friedlander R, Aull M, Putheti P, Sharma V, Suthanthiran M, Dadhania D Abstract The relationship between circulating pre-transplant immunoglobulin G (IgG) antibodies to donor human leukocyte antigen (HLA) -C locus determined antigens alone and acute rejection, kidney allograft function, and graft survival is not fully defined. Also, the impact of circulating pre-transplant IgG antibodies to donor HLA-C locus antigens alone on these outcomes has not been compared with the impact of circulating pre-transplant IgG antibodies to donor HLA-A or -B locus antigens. We conducted a retrospective review of records of 1252 kidney allograft recipients transplanted at our center between January 2010 and January 2016 to identify patients with circulating pre-transplant IgG antibodies directed at kidney donor HLA-A, -B, or -C locus determined antigens. Antibodies were detected and reported using the LABScreen Single Antigen Bead assay with microbeads coated with single HLA class I antigens. Pre-transplant and post-transplant data were collected and the graft outcomes of 16 kidney graft recipients with antibodies to HLA-C locus antigens were compared to the outcomes in 56 recipients with antibodies to HLA-A or -B ...
