    Northwestern University, Chicago.

    Introduction: Recipients with broad sensitization to HLA defined by a high percentage of Panel Reactive Antibodies (PRA) are at higher immunologic risk for poor graft…

    Impact of Angiotensin II Type I Receptor Antibody Positivity in Highly-HLA Sensitized (HS) Patients Transplanted After Desensitization (DES).

    A. Vo,1 C. Boutsicaris,1 X. Zhang,2 N. Reinsmoen,2 J. Choi,1 S. Jordan.1

    1Kidney Transplant, Cedars-Sinai Medical Center, LA, CA; 2HLA Laboratory, Cedars-Sinai Medical Center, LA, CA.

    Introduction: Angiotensin II type I receptor antibody (AT1R Ab) is a target for non-HLA antibodies. AT1R ab exert direct effects on endothelial and vascular smooth…

    Outcomes of Untreated Asymptomatic Bacteriuria in Renal Transplant Recipients: A Single-Center Experience.

    W. Davis, R.-A. Lee, L. Daniels, S. Todd, K. True, P. Chong.

    University of North Carolina Medical Center, Chapel Hill, NC.

    Background. Renal transplant recipients (RTR) with asymptomatic bacteriuria (AB) are often treated with antibiotics. This could lead to complications related to antibiotic treatment including Clostridium…

    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-…
  • 2016 American Transplant Congress

    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…
