85 Antibody-Mediated Rejection after Lung Transplantation

Acute antibody-mediated rejection after lung transplantation.

BACKGROUND Antibody-mediated rejection (AMR) after lung transplantation remains enigmatic, and there is no consensus on the characteristic clinical, immunologic and histologic features. METHODS We performed a retrospective, single-center cohort study and identified cases of acute AMR based on the presence of circulating donor-specific human leukocyte antigen (HLA) antibodies (DSA), histologic...

Current perspectives on antibody-mediated rejection after lung transplantation

Acute antibody-mediated rejection after intestinal transplantation

AIM To investigate the incidence, risk factors and clinical outcomes of acute antibody-mediated rejection (ABMR) after intestinal transplantation (ITx). METHODS A retrospective single-center analysis was performed to identify cases of acute ABMR after ITx, based on the presence of donor-specific antibody (DSA), acute tissue damage, C4d deposition, and allograft dysfunction. RESULTS Acute AB...

Antibody-mediated rejection in lung transplantation: fable, spin, or fact?

The lung transplant community continues to struggle with the diagnosis and management of antibody-mediated rejection. The four diagnostic tenets of donor-specific antibodies, C4d staining, histopathologic changes, and allograft dysfunction, which were largely derived from the early Banff meetings on renal transplantation, have somewhat arbitrarily been applied to lung transplantation. With the ...

Antibody-mediated rejection in lung transplantation: myth or reality?

Whether antibody-mediated rejection after lung transplantation exists as an entity is debated by immunologists, histopathologists, and clinicians, without a strong consensus regarding diagnostic characteristics despite an increasing body of evidence that attests to a significant role in other solid organ transplant disciplines. Evidence for and against the protean manifestations of antibody-med...
