  • 2016 American Transplant Congress

    Late Renal Allograft Rejection Is Predicted by High Intrapatient Variability of Tacrolimus Levels.

    D. Goodall, M. Willicombe, A. McLean, D. Taube.

    Imperial College Renal and Transplant Centre, Imperial College NHS Trust, London, United Kingdom.

    IntroductionNonadherence to immunosuppressive medication is associated with rejection and graft loss. We have previously shown that intrapatient variability (IPV) of tacrolimus trough levels between 6-12…

    Incidence & Impact of De Novo DSA (dnDSA) Formation on Transplant Outcomes in HLA-Sensitized (HS) Patients Transplanted After IVG+Rituximab Desensitization (DES).

    A. Vo,1 J. Choi,1 J. Kahwaji,1 J. Mirocha,2 A. Peng,1 R. Villicana,1 S. Jordan.1

    1Kidney Transplant, Cedars-Sinai Medical Center, LA, CA; 2Research Institute, Cedars-Sinai Medical Center, LA, CA.

    Introduction: Highly-HLA sensitized patients are at risk for developing donor specific antibodies (DSA) & ABMR post-transplant (tx). However, incidence and risk of acute rejections (AR)…

    Efficacy and Renal Function in Kidney Transplant Recipients Receiving Tacrolimus (TAC)-Based Immunosuppressive Regimens in Combination with Everolimus (EVR) versus Mycophenolate (MPA).

    A. Brigido, H. Tedesco, C. Felipe, M. Cristelli, M. Franco, J. Medina-Pestana.

    Nephrology Division, Hospital do Rim - UNIFESP, Sao Paulo, Brazil.

    Acute rejection and renal function are associated with long-term renal allograft survival. We evaluated these outcomes in patients receiving reduced TAC exposure combined with EVR…

    Relationship Between Mean Fluorescence Intensity and C1q/C3d-Fixing Capacities of Anti-HLA Antibodies.

    G. Claisse,1 L. Absi,2 E. Alamartine,1 N. Maillard,1 C. Mariat.1

    1Centre Hospitalier Universitaire - Hôpital Nord, Saint-Etienne, France; 2Laboratoire EFS Loire-Auvergne, Saint-Etienne, France.

    The capacity of anti-HLA antibodies (Abs) to activate complement is thought to be an informative property susceptible to facilitate outcome prediction. Two different tests, C1q-…

    Molecular Profiles of Renal Allograft Rejection.

    Z. Hajjiri, P. Finn, D. Perkins.

    Internal Medicine/Renal Medicine, University of Illinois at Chicago, Chicago, Il.

    Introduction: The gold standard for the diagnosis of allograft rejection is the Banff Classification, yet it shows substantial variability among pathologists. Using molecular signatures of…

    ASC-Deficient Dendritic Cells Exhibit Activation Defects and a Reduced Ability to Stimulate Allogeneic T Cells.

    A. Scheinok, A. Shigeoka, S. Kasimsetty, R. Elahimehr, D. McKay.

    Medicine, University of California-San Diego, La Jolla, CA.

    Donor dendritic cell (DC) activation causes adaptive immune responses that lead to rejection of transplanted allografts. Accumulating data suggest that inflammasome assembly within interstitial DCs…

    Higher Pre-Transplant Triglyceride Levels Are Associated with Increased Acute Cellular Rejection Risk Following Kidney Transplant.

    J. Hagopian,1 D. Brennan,2 K. Lentine,3 T. Horwedel.1

    1Barnes-Jewish Hosp, St. Louis, MO; 2Washington Univ, St. Louis, MO; 3St. Louis Univ, St. Louis, MO.

    Purpose:Hyperlipidemia (HLD) has been associated with more robust immune response, possibly increasing risk for rejection. Recent articles have associated HLD with increased IL-17 production and…

    Eculizumab for Chronic Antibody-Mediated Injury in Kidney Transplant Recipients: A Randomized-Controlled Trial.

    S. Kulkarni,1 N. Kirkiles-Smith,2 Y. Deng,3 R. Formica,4 M. Gilbert,5 V. Broeckner,6 L. Bow,1 J. Pober.2

    1Surgery, Yale University, New Haven, CT; 2Immunobiology, Yale University, New Haven, CT; 3Yale Center for Analytical Sciences, Yale School of Public Health, New Haven, CT; 4Medicine, Yale University, New Haven, CT; 5Pathology, Yale University, New Haven, CT; 6Histopathology, Univeristy of Cambridge, Cambridge, United Kingdom.

    Purpose: We hypothesize that de novo donor specific antibody (DSA) in kidney transplant patients cause endothelial cell injury that is dependent on complement and treatment…

    Outcome of the Various Pathology Grades of Antibody-Mediated Rejection After Heart Transplantation.

    J. Patel, M. Kittleson, D. Chang, T. Aintablian, L. Czer, A. Trento, J. Kobashigawa.

    Cedars-Sinai Heart Institute, Los Angeles, CA.

    Background: The pathology scale for antibody-mediated rejection (AMR) was approved by the board of directors in 2013. The ISHLT AMR grading scale consists of pAMR…

    Prospective Single Antigen Bead Epitope-Based Clustering for Early Detection of Antibody Mediated Rejection.

    A. Lichvar, S. Tremblay, P. Brailey, A. Girnita, R. Alloway, E. Woodle.

    U of Cincinnati, Cincinnati.

    Purpose:Epitope-based groups of HLA single antigen beads (SAB) often demonstrate clustering in patients with donor specific antibodies (DSA). Coordinated Mean Florescent Intensity (MFI) increases of…
