Patients with C-aABMR and V-Lesions in Their Renal Transplant Biopsy Have a Superior Response to Treatment
K. Sablik, M. Clahsen-van Groningen, C. Looman, M. Betjes.
Erasmus Medical Center, Rotterdam, Netherlands.
Introduction Chronic active antibody mediated rejection (c-aABMR) in the renal allograft may occur with isolated arteritis. Isolated v-lesions have been associated with an inferior graft…
