Core Tip

Core tip: Chronic-active antibody-mediated rejection (cAMR) is one of the major causes of poor long-term outcome in kidney transplantation, with no effective treatments currently available. We retrospectively compared 21 kidney transplant recipients with a diagnosis of cAMR, nine treated with plasmapheresis, intravenous immunoglobulins and rituximab vs 12 patients not treated with antibody-targeted therapies. Our data showed improvement in microvascular inflammation in post-therapy protocol biopsies without differences in functional outcomes at 24 mo, suggesting the lack of a prompt and marked effect of this therapeutic protocol. Further studies are required to improve the management and long-term results of this severe condition.
