Bortezomib in kidney transplant recipients with antibody mediated rejection: three case reports.

Here, we report our experience on three patients with AMR who were treated with bortezomib after other therapeutic interventions had failed. Bortezomib was well tolerated by two of the three patients. The third patient developed worsening thrombocytopenia following the second dose. Despite a low adverse event profile, none of the three patients conclusively responded to the bortezomib treatment. As a result of the difference in our results from that of other centers we feel that a larger prospective study is needed to define appropriate guidelines for the use of bortezomib in cases of acute rejection.
