  • 2019 American Transplant Congress

    Increasing Net Immunosuppression after BK Viremia

    L. Cotiguala, A. Masood, J. Park, A. Naik

    University of Michigan, Ann Arbor, MI

    *Purpose: BK viremia is associated with inferior kidney allograft outcomes. Typical treatment involves reduction in immunosuppression. However reduction in immunosuppression is also likely to lead…

    Exosomes Isolated from Human Lung Transplant Recipients Diagnosed with Bronchiolitis obliterans Syndrome are Unique in Their Ability to Induce IL-6 via Rab27A Signaling Pathway

    M. Rahman, M. Sharma, S. Angara, M. Smith, R. Bremner, T. Mohanakumar

    Norton Thoracic Institute, St. Joseph’s Hospital and Medical Center, Phoenix, AZ

    *Purpose: Rab27, a member of the Rab subfamily of GTPases, has the ability to induce exosome secretion. Exosomes are small membrane vesicles (40-150nm) that regulate…

    Transcriptome Profiling Of Renal Transplant Biopsies With Acute Cellular Rejection From Patients On Calcineurin Inhibitor-based Or Cni-avoidance Immunosuppression

    D. Dobi1, F. Vincenti2, Z. G. Laszik1

    1Department of Pathology, University of California, San Francisco, San Francisco, CA, 2Departments of Medicine and Surgery, University of California, San Francisco, San Francisco, CA

    *Purpose: Despite their suboptimal toxicity profile, calcineurin-inhibitors (CNIs) remain the cornerstone of renal transplant immunosuppression. Previous efforts to completely eliminate CNIs failed, because CNI-avoidance protocols…

    Donor-Derived Cell-Free DNA is Associated Specifically with Antibody Mediated Injury in Patients with Renal Allograft Dysfunction

    B. Obrisca1, C. Blosser2, I. De Castro2, C. Johnson2, B. Sorohan1, L. Sibulesky2, R. Bakthavatsalam2, G. Ismail1, N. Leca2

    1Fundeni Clinical Institute, Bucharest, Romania, 2University of Washington, Seattle, WA

    *Purpose: Donor-derived cell-free DNA (dd-cfDNA) has been proposed as a noninvasive biomarker to differentiate rejection from other types of injury in renal allografts.*Methods: We analyzed…

    Outcomes of ABO Incompatible Transplant on Steroid Free Immunosuppression

    A. Wang, D. Mishler, T. Taber, M. Yaqub, A. Sharfuddin, W. Goggins, O. Adebiyi

    Department of Medicine, Division of Nephrology, Indiana University School of Medicine, Indianapolis, IN

    *Purpose: ABO incompatible (ABOi) kidney transplant (KTx) was introduced to expand donor organ pool. However it is also an immunologically high-risk procedure requiring pre-transplant antibody…

    Subclinical Antibody Mediation Rejection in Stable Kidney Recipients with De Novo Donor Specific Antibodies and Correlation with Donor Derived Cell Free DNA Testing

    A. P. Bregman, E. J. Stites, J. Gralla, A. Wiseman, J. E. Cooper

    Kidney and Pancreas Transplant, University of Colorado-Denver, Aurora, CO

    *Purpose: Subclinical antibody mediated rejection (sAMR) is associated with inferior graft outcomes but its diagnosis relies on the presence of biomarkers as well as histology.…

    Low Dose Anti-Thymocyte Globulin is Enough to Prevent Acute Cellular Rejection in Kidney Transplant

    P. W. Baron1, J. Weissman2, F. Fazeli3, C. Zuppan4, R. Villicana3, P. Wai1, L. Beeson5, M. De Vera1

    1Surgery/Transplantation Institute, Loma Linda University Health, Loma Linda, CA, 2Pharmacy, Loma Linda University Health, Loma Linda, CA, 3Transplantation Institute, Loma Linda University Health, Loma Linda, CA, 4Pathology, Loma Linda University Health, Loma Linda, CA, 5Center for Nutrition, Healthy Lifestyle and Disease Prevention/School of Public Health, Loma Linda University Health, Loma Linda, CA

    *Purpose: Rabbit anti-thymocyte globulin (rATG) cumulative dose needed to effectively and safely prevent acute cellular rejection is unknown. This study compares the efficacy of total…

    Urinary Microtubule-Associated Protein Light Chain3 and Neutrophil Gelatinase-Associated Lipocalin, as Potential Noninvasive Biomarkers for Subclinical Rejection at 3 Months after Kidney Transplantation

    S. Tajima1, R. Fu2, M. Fukuda2, K. Suetsugu2, Y. Okabe3, S. Masuda1

    1Pharmacy, Kyushu University Hospital, Fukuoka, Japan, 2Clinical Pharmacology and Biopharmaceutics, Graduate School of Pharmaceutical Sciences, Kyushu University, Fukuoka, Japan, 3Surgery and Oncology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan

    *Purpose: Biopsy proven acute rejection without clinical symptoms such as subclinical rejection (SCR) is supposed to associate graft loss in the long term post kidney…

    Racial Disparities in Documentation of Non-Adherence and Its Relation to Rejection in Pediatric Kidney Transplant Recipients

    T. Melanson, J. Hogan, K. Maroney, R. Patzer, R. George

    Emory University, Atlanta, GA

    *Purpose: Black patients have historically been disadvantaged throughout the transplant process. Many factors impact the success of kidney transplantation, but the need for strict adherence…

    Is Pre-transplant Plasmapheresis For Patients With Insignificant Abo Blood Type Antibody In Abo Blood Type Incompatible Kidney Transplant Necessary? – A Japanese Single Center Study.

    M. Miyazaki, A. Mitsuke, H. Higuchi, N. Fukuzawa, H. Tanaka, T. Hirano, T. Seki, H. Harada

    Urology and Kidney Transplant Surgery, Sapporo City General Hospital, Sapporo, Hokkaido, Japan
