Long-term graft survival in patients with chronic antibody-mediated rejection with persistent peritubular capillaritis treated with intravenous immunoglobulin and rituximab.

Chronic antibody-mediated rejection (cAMR) is the major cause of premature renal allograft loss and is resistant to therapy with 12-month graft failure of up to 50% reported. We examined the duration of graft survival and associates of graft failure in patients with donor-specific antibody-positive cAMR and treatment-resistant peritubular capillaritis between June 2007 and October 2010. Those with advanced interstitial fibrosis (n=5) were excluded.
