Long Term Outcomes Following Antibody Mediated Rejection (AMR) in Renal Transplant Recipients.
R. Crew, S. Patel, H. Morris, M. Chiles, L. Ratner.
Columbia University, New York.
INTRO: Progress in AMR treatment has improved early graft survival. Since the new kidney allocation system results in more sensitized patients getting transplanted, we expect…
