Abstract
Antibody-mediated rejection (AMR) typically occurs early after transplantation in approximately 5%–7% of recipients. The literature reports suggest that 12%–37% of kidney transplant recipients with acute AMR do not respond to treatment and eventually lose their grafts. The proteasome inhibitor bortezomib is currently approved by the Food and Drug Administration for the treatment of multiple myeloma. It has been demonstrated both in vitro and in vivo to possess apoptotic properties against mature plasma cells. Herein we have described a series of 3 patients with positive cross-matches who developed early AMR after kidney transplantation. Bortezomib rescue treatment was administered after the patients failed to respond to plasmapheresis/intravenous immunoglobulin and splenectomy. All 3 patients responded with full, durable recovery of renal function. In conclusion, bortezomib is useful to treat refractory AMR after kidney transplantation.
