Abstract

Background: The 2013 Banff meeting updated the requirements for the diagnosis of acute/active antibody-mediated rejection (AAMR) in kidney allografts. There has been speculation that the changes lower the threshold for diagnosing AAMR, and may lead to possible unnecessary and expensive treatment. Methods: We compared the 2013 Banff classification for AAMR to the previous 2007 Banff to determine if there was an increase in the number of patients receiving a diagnosis of AAMR and if the diagnosis affected allograft survival and post-biopsy 3-month and 6-month creatinine and eGFR values. Results: A total of 212 renal allograft biopsies were compared to both 2007 and 2013 Banff classification requirements for AAMR. Ten patients (11 biopsies) met the 2007 criteria. An additional 15 patients (20 biopsies) met the 2013 criteria. These 2 groups showed no statistically significant demographic differences. By applying the 2013 Banff classification, we observed a 2.5-fold increase in the number of AAMR cases. One-year post-transplant allograft survival was higher in the 2013 group (.85 vs.55) and the 3-month and 6-month post-biopsy creatinine values were significantly lower for the 2013 group (1.6 ±.6 vs 3.3 ± 2.2, P value.01, and 1.7 ±.6 vs 3.4 ± 2.8, P value.03). The 3-month and 6-month eGFR values were higher in the 2013 group, although not statistically significant. Conclusions: These results suggest that use of Banff 2013 criteria in place of Banff 2007 may result in diagnosing milder and earlier cases of AAMR with the possibility of initiating earlier treatment and improving graft outcomes.
