Although considered the gold standard, histologic examination of renal transplant biopsies, expert pathologists frequently disagree on their interpretation of the same sample. The authors of this paper have developed criteria for antibody-mediated rejection based on mRNA expression in biopsy samples detected by microarrays. In this study, they validate their previous findings in a cohort of […]

The ability to detect anti-HLA antibodies is very sensitive and specific, but it is not clear if all antibodies are the same. Specifically, some antibodies may bind and activate complement better than others. In this retrospective study, the presence of antibodies that could fix C1q and initiate the complement cascade was associated with higher rates […]

Approximately 10 – 20% of heart transplant recipients will develop AMR. Standardized nomenclature has improved the diagnosis. This single center study revisits the risks of Class I and II DSA to C4D +IF and graft failure. C4d staining correlated better with graft failure in patients with DSA to only Class I or DSA to both […]
