Brief Summary
The purpose of the study is to assess the efficacy of bortezomib, in association with steroids, plasma exchange, and polyclonal intravenous immunoglobulins, in the treatment of chronic antibody mediat...
Detailed Description
Chronic active antibody-mediated rejection (AMR) is considered as a main cause of late allograft losses in kidney transplant recipients. It is due to the occurrence of de novo donor-specific anti-HLA ...

- age over 18 years
- with de novo donor specific antibodies (DSA), i.e. antibodies not detected the day of transplantation and in pre-transplant sera
- with histological lesions of chronic active antibody-mediated rejection (glomerulitis + peritubular capillaritis banff score and chronic glomerulopathy (g+ptc ≥ 2) on a graft biopsy performed because of renal function deterioration, proteinuria, detection of de novo DSA, or on a systematic biopsy
