Background: The updated BANFF 2013 criteria has enabled a more standardized and complete serologic and histopathologic diagnosis of chronic active antibody mediated rejection (cAMR). Little data exists on the outcomes of cAMR since the initiation of this updated criteria.

Methods: 123 consecutive patients with biopsy proven cAMR (BANFF 2013) between 2006 and 2012 were identified.

Results: Patients identified with cAMR were followed for a median of 9.5 (2.7-20.3) years after transplant and 4.3 (0-8.8) years after cAMR. Ninety-four (76%) recipients lost their grafts with a median survival of 1.9 years after diagnosis with cAMR. Mean C4d and allograft glomerulopathy scores were 2.6 ± 0.7 and 2.2 ± 0.8, respectively. 53.2% had class II DSA, 32.2% had both class I and II, and 14.5% had class I DSA only. Chronicity score >8 (HR 2.9, 95% CI 1-8.4, p=0.05), DSA >2500 MFI (HR 2.8, 95% CI 1.1-6.8, p=0.03), Scr >3mg/dL (HR 3.2, 95% CI 1.6-6.3, p=0.001) and UPC >1g/g (HR 2.5, 95% CI 1.4-4.5, p=0.003) were associated with a higher risk of graft loss.

Conclusions: cAMR was associated with poor graft survival after diagnosis. Improved therapies and earlier detection strategies are likely needed to improve outcomes of cAMR in kidney transplant recipients.
