Can antibodies be rejected?
Antibody-mediated rejection can be a recalcitrant process, resistant to therapy and carries an ominous prognosis to the graft.
How is antibody-mediated rejection treated?
Clinical manifestations of AMR include proteinuria and a rise in serum creatinine. Current strategies for the treatment of AMR include antibody depletion with plasmapheresis (PLEX), immunoadsorption (IA), immunomodulation with intravenous immunoglobulin (IVIG), and T cell– or B cell–depleting agents.
What is antibody rejection in kidney transplant?
Antibody-mediated rejection (AMR), also known as B-cell-mediated or humoral rejection, is a significant complication after kidney transplantation that carries a poor prognosis. Although fewer than 10% of kidney transplant patients experience AMR, as many as 30% of these patients experience graft loss as a consequence.
How does antibody-mediated rejection occur?
AMR results from activation of the classical pathway of the complement system by antibodies against the donor HLA present on the endothelium. These antibodies may be preformed prior to transplantation or can arise de novo after transplantation.
What is chronic rejection?
Chronic rejection (CR) is an immune phenomenon characterized by vasculopathy (intimal hyperplasia, perivasculitis obliterative endarteritis of graft vessels), fibrosis, and atrophy of graft with progressive loss of function that culminates in graft loss. The pathogenesis of CR is poorly defined.
Can antibodies be transplanted?
In this case, you have antibodies towards your donor, but it is safe to cautiously undergo transplantation at a specialized transplant center with expertise in this particular area. You may need special treatments such as plasmapheresis and/or intravenous immunoglobulin (IVIG) to undergo this type of transplant.
How is kidney rejection treated?
How is rejection treated? If a diagnosis of rejection is made, your doctor will prescribe medication to treat the rejection and prevent further complications. You may be admitted to the hospital for three to five days for treatment or be treated for three days in the outpatient setting.
How is chronic kidney rejection treated?
Kidney transplantation is currently the definitive treatment for patients with end-stage kidney disease (ESKD). Compared to dialysis, kidney transplantation is associated with reduced mortality and improved quality of life. Rejection of the kidney is one of the leading causes of allograft loss.
How is acute kidney rejection treated?
Treatment of acute cellular rejection in kidney transplant recipients include pulse steroid for the first rejection episode. It can be repeated for recurrent or resistant rejection. Thymoglobulin and OKT3 are used as the second line of treatment if graft function is deteriorating.
What happens when an organ is rejected?
When a patient receives an organ transplant, the immune system often identifies the donor organ as “foreign” and targets it with T cells and antibodies made by B cells. Over time, these T cells and antibodies damage the organ, and may cause reduced organ function or organ failure. This is known as organ rejection.
