Donor-Specific HLA Antibody IgG Subclasses Are Associated with Phenotypes of Antibody-Mediated Rejection in Sensitized Renal Allograft Recipients.

Donor-specific anti–histocompatibility leukocyte antigen antibodies (DSAs) have a strong and frequently considered universally deleterious effect on allografts. Preformed or de novo DSAs activate complement, induce endothelial cell proliferation, and mediate antibody-dependent cellular cytotoxicity (ADCC), resulting in progressive declines in allograft function and loss.1–3More than 5000 renal ...

Acute antibody-mediated renal allograft rejection associated with HLA-Cw17 antibody

Detection of donor-specific human leukocyte antigen (HLA) antibodies is an important part of diagnosis of antibody-mediated rejection (AMR) in the renal transplant population. Donor-specific antibodies (DSA) against HLA-C, a Class 1 major histocompatibility gene product, are not considered to be of major importance in renal transplant rejection. Typing for HLA-C is not a routine part of pre- an...

Antibody-Mediated Kidney Allograft Rejection

Successful kidney transplantation improves the quality of life and increases survival when compared with long-term dialysis. Renal transplantation is now a well established and the preferred treatment for most patients with end-stage renal disease (ESRD). In recent years, the short-term effects of kidney transplantation have been greatly achieved due to the improvement in immunosuppression medi...

Anti-glutathione S-transferase T1 antibody-mediated rejection in C4d-positive renal allograft recipients.

BACKGROUND Chronic humoral rejection is a progressive form of graft injury, with defined diagnostic criteria, the crucial one being the evidence of circulating anti-donor antibodies. These antibodies are mainly directed against human leucocyte antigens (HLA), but other targets have also been described. We previously reported that antibodies against the Glutathione S-transferase T1 (GSTT1) enzym...

Antibody-mediated renal allograft rejection: diagnosis and pathogenesis.

Alloantibodies to HLA class I or II and other antigens expressed by endothelium cause a variety of effects on renal transplants, ranging from acute to chronic rejection, and even apparent graft acceptance (accommodation). Recognition of these conditions and appropriate therapy requires demonstration of C4d in biopsies, commonly confirmed by tests for circulating alloantibody. Substantial practi...
