    1Pediatric Nephrology, Emory University & Children's Healthcare of Atlanta, Atlanta, GA; 2Dept. of Pathology, Emory Transplant Center, Emory University, Atlanta, GA.

    Background: De-novo donor specific antibody (DSA) is one of the strongest independent predictors of graft loss with HLA mismatching being a major risk factor for…

    Feasibility of a National Class II Matching Strategy for Pediatric Kidney Transplant Candidates

    T. Blydt-Hansen,1 W. Klement,2 K. Tinckam,3 J. Gill.1

    1University of British Columbia, Vancouver, Canada; 2Canadian Blood Services, Ottawa, Canada; 3University of Toronto, Toronto, Canada.

    High Frequency of HLA-DQ De Novo Donor Specific Antibodies is Independent of the Number of Mismatches in Heart Transplant

    X. Zhang,1 E. Kransdorf,2 J. Patel,2 J. Kobashigawa.2

    1HLA and Immunogenetics Laboratory/ Comprehensive Transplant Center, Cedars-Sinai Health Systems, Los Angeles, CA; 2Cardiology, Cedars-Sinai Medical Center, Los Angeles, CA.

    Aim: Development of de novo donor specific antibodies (DSA) after heart transplant is associated with an increased risk of allograft failure. The aim of this…

    Shared HLA Specificities between the Blood and Transplant Donor Increases the Risk of De Novo DSA Development Following Blood Transfusion in Transplant Recipients

    S. Hassan,1 F. Regan,2 C. Brown,3 A. Harmer,2 N. Anderson,2 E. Santos,4 P. Brookes,4 D. Taube,1 M. Willicombe.1

    HLA Eplet Mismatch and Donor Specific Antibodies in Kidney Transplantation

    S. Wan,1,2 S. Angel de Wilde,2 B. Rosales,2 S. Chadban,1,2 K. Wyburn.1,2

    1Department of Renal Medicine, Royal Prince Alfred Hospital, Sydney, Australia; 2Sydney Medical School, University of Sydney, Sydney, Australia.

    BACKGROUND: Although HLA matching improves graft survival in kidney transplant recipients (KTx), eplet mismatches provide higher resolution information, and could better predict the development of…

    The Results of Plasmapheresis and Anti-CD20 Based Desensitization without Intravenous Immunoglobulin in Positive Crossmatch Kidney Transplants

    H. Kwon, Y. KIm, J. Choi, S. Shin, J. Jung, M. Cho, J. Kim, D. Han.

    Asan Medical Center, Seoul, Korea.

    This study examined the mid-term clinical outcomes in positive crossmatch kidney transplants (XMKT) for patients who received desensitization with plasmapheresis (PP) and anti-CD20 based regimens…

    Temporal Changes in Impact of HLA Mismatch among Pediatric Kidney Transplant Recipients

    J. Ruck, A. Massie, N. Desai, D. Segev, J. Garonzik-Wang.

    Johns Hopkins University School of Medicine, Baltimore, MD.

    U.S. pediatric deceased-donor kidney transplantation (pDDKT) allocation now deemphasizes HLA matching to improve equality in access to transplantation, but other national systems still consider HLA…

    Validation of a Novel Computational Approach for Predicting HLA Immunogenicity Based on Quantification of Structural and Surface Electrostatic Potential Differences Between Donor and Recipient HLA.

    V. Kosmoliaptsis,1 C. Kling,2 M. Robb,3 D. Collett,3 J. Bradley,1 C. Taylor,1 D. Kabelitz,2 D. Mallon.1

    1Department of Surgery, University of Cambridge, Cambridge, United Kingdom; 2University of Kiel, Kiel, Germany; 3NHS Blood and Transplant, Bristol, United Kingdom

    Background: Our preliminary work indicates that donor HLA immunogenicity in kidney and haematopoietic stem cell transplantation can be predicted by comparative assessment of donor and…
