Rituximab and intravenous immunoglobulin treatment of chronic antibody-mediated kidney allograft rejection

Abstract

Kidney transplant rejections are classified into T-cell-mediated and antibody-mediated rejections (AMR). C4d staining on allograft biopsies and solid-phase assays to measure donor-specific alloantibodies have helped to precisely define the latter. Although for acute AMRs, therapy mainly relies on plasmapheresis or immunoadsorption, no studies for treatment of chronic AMR are available. Here, we report on four kidney allograft recipients suffering from chronic AMR 1 to 27 years posttransplant, who were treated with a combination of rituximab and intravenous immunoglobulin (IVIG). Rituximab/IVIG improved kidney allograft function in all four patients, whereas donor-specific antibodies were reduced in 2 of 4 patients. However, in one patient an acute rejection episode occurred 12 months after this treatment, and another patient had severe, possibly rituximab-associated lung toxicity. Thus, rituximab/IVIG may be a useful strategy for the treatment of chronic AMR, but further randomized multicenter studies are necessary to establish its efficacy and safety profile.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
