Acute, Chronic, and Humoral Rejection

Under current immunosuppressive regimes, T-cell –mediated acute and chronic rejection remain common and important posttransplant complications. The definition of humoral (antibody-mediated) rejection has been greatly expanded in recent years. The histopathologic assessment of allograft biopsies continues to serve an important role in the diagno sis of rejection and to facilitate patient management. The diagnosis of both acute and chronic antibody-mediated rejection requires integration of the results of donor-specific antibody testing and C4d immunostaining, as well as exclusion of other potential etiologies of allograft dysfunction. Chron ic antibody-mediated rejection should also be included in the differential diagnosis for unexplained allograft fibrosis.
