    Persistence/Progression of Early Banff Borderline Changes (BBC) Is Associated with Chronic Renal Allograft Damage and Can Be Predicted by B Cell Cytokine Profile.

    A. Cherukuri, A. Sharma, R. Mehta, S. Hariharan, D. Rothstein.

    UPMC, Pittsburgh

    The clinical significance of early histological BBC in kidney transplant recipients (KTR) is unclear. It is also unknown if biomarkers predict progression to acute rejection…

    Tacrolimus Trough Concentration Variability and Disparities in African American Kidney Transplantation.

    D. Taber, Z. Su, A. Posadas, M. Gebregziabher, L. Egede, D. Dubay, J. McGillicuddy, C. Bratton, S. Nadig, K. Chavin, P. Baliga.

    MUSC, Charleston, SC

    Low tacrolimus (FK) trough concentrations have been associated with higher risk of acute rejection, particularly within African-American (AA) kidney transplant recipients; less is known about…

    Differential Expression of Long Noncoding RNAs During Cardiac Allograft Rejection.

    G. Gu, H. Hang, T. Lu, Q. Xia.

    Department of Hepatic Surgery, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai, China

    While transplant rejection is the major restriction in successful long lasting graft survival, induction of sustainable immune tolerance against transplant is one of the major…

    Neutropenia in Kidney Transplantation: A Hidden Threat to Graft Survival.

    A. Vergottini, A. Karabala, P. Abrams, J. Verbesey, S. Ghasemian, J. Moore, M. Grafals, B. Javaid, M. Cooper, A. Gilbert.

    Medstar Georgetown Transplant Institute, Washington, DC

    IntroductionNeutropenia is a common complication after kidney transplantation resulting in a reduction of immunosuppression and the use of granulocyte colony-stimulating factors (G-CSF) which can increase…

    Not All Cellular Rejections Are the Same: Differences in Early and Late Hepatic Allograft Rejection.

    C. Jadlowiec, P. Morgan, A. Nehra, M. Hathcock, W. Kremers, R. Wiesner, T. Taner.

    Mayo Clinic, Rochester, MN

    While acute cellular rejection (ACR) after liver transplantation (LT) is not thought to cause long-term graft injury and inferior outcomes, this notion has been challenged…
  • 2017 American Transplant Congress

    Development of De Novo Donor Specific Antibodies (dnDSAs) Not the Presence of Pre-Transplant Donor Specific Antibodies (Pre-DSAs) Increase Rejection Risk in Crossmatch Negative Kidney Transplant Recipients.

    H. Khamash, L. Archambault, M. Buras, H. Kosiorek, M. Pando, K. Reddy, B. Kaplan, R. Heilman.

    Mayo Clinic Arizona, Phoenix, AZ

    Which Is More Nephrotoxic to Kidney Transplants: BK Nephropathy or Rejection?

    S. Parajuli, B. Astor, D. Kaufman, B. Muth, M. Mohamed, N. Garg, A. Djamali, D. Mandelbrot.

    University of Wisconsin, Madison

    The relative nephrotoxicity of BK nephropathy (BKN) vs acute rejection is unknown. This is an important question, since clinicians often must choose between reducing immunosuppression…

    Molecular Classifier of Antibody-Mediated Rejection Is a Better Predictor of Histologic Rejection Than a Corresponding Transcript Set and Is Further Improved When Combined with Classifiers of Rejection Syndromes.

    K. Famulski, P. Halloran.

    University of Alberta, Edmonton, AB, Canada

    Molecular and histologic changes in graft rejection are not completely specific, often being induced by injuries and other diseases. We examined various methods for using…
