Analyzing Causes for Death-Censored Graft Failure
M. Mayrdorfer, L. Liefeldt, N. Lachmann, W. Düttmann-Rehnolt, F. Halleck, M. G. Naik, P. Glander, K. Budde
Charité Universitätsmedizin Berlin, Berlin, Germany
*Purpose: Since it has been proposed that several causes could contribute to graft loss (GL), we analyzed graft failure in our center and attributed a…

The Role of the Molecular Microscope to Guide Therapy for T-Cell Mediated Rejection in Kidney Transplants
D. Kumar¹, M. Demehin¹, J. Christensen¹, L. Kamal¹, I. Moinuddin¹, M. Levy¹, C. Bhati¹, A. King¹, H. D. Massey¹, P. Halloran², G. Gupta¹
¹Virginia Commonwealth University, Glen Allen, VA, ²ATAGC, Edmonton, AB, Canada
*Purpose: Histologic lesions (I+T) to characterize T-cell mediated rejection (TCMR) can be non-specific. In some cases the inflammation may represent a ‘response to wounding’ rather…

Incidence of Antibody Mediated Rejection in Living Kidney Transplant Recipients with Sensitizing History
Y. Kakuta¹, M. Okumi¹, T. Kanzawa¹, K. Unagami², H. Ishida², K. Tanabe¹
¹Urology, Tokyo Women's Medical University, Tokyo, Japan, ²Organ Transplant Regulation, Tokyo Women's Medical University, Tokyo, Japan
*Purpose: A donor-reactive alloimmune memory response can arise from prior exposure to foreign human leukocyte antigen by sensitization history in transplant recipients. Assessing risk levels…

Hepatocellular Carcinoma Recurrence after Severe Acute Cellular Rejection
M. Najjar¹, O. Perez¹, K. Bruestle¹, A. Qian¹, P. Jiang¹, A. Srivastava¹, Y. Saenger¹, E. Verna¹, E. Zheng¹, A. Mathur¹, A. Griesemer¹, K. Halazun², B. Samstein², T. Kato¹, J. Emond¹
¹Columbia University Irving Medical Center, New York, NY, ²Weill Cornell Medicine, New York, NY
*Purpose: The interplay between acute cellular rejection (ACR), immunosuppression and hepatocellular carcinoma (HCC) recurrence in patients who underwent liver transplantation (LT) for HCC is still…

Belatacept Combined with BTLA Prolong Allogeneic Kidney Graft Survival and Inhibited Acute Rejection after Kidney Transplantation
H. Zhang, Z. Wang, J. Zhang, Z. Han, J. Tao, H. Chen, L. Sun, R. Tan, M. Gu
Jiangsu Province Hospital, Nanjing, China
*Purpose: Belatacept as a high-affinity variant of CTLA-4Ig, has been applied into kidney transplantation to against acute rejection. However, adoption of Belatacept has been limited…

Clazakizumab (Anti-IL-6 Monoclonal) as an Agent to Reduce Donor Specific Hla Antibodies (DSA) and Improve Outcomes in Patients with Chronic & Active Antibody-Mediated Rejection Post-Kidney Transplantation (NCT03380377)
S. C. Jordan, N. Ammerman, M. Toyoda, S. Ge, E. Huang, A. Peng, S. Sethi, R. Najjar, E. Ortiz, M. Chu, A. De Guzman, I. Kim, K. Lim, J. Choi, A. Vo
Cedars Sinai Medical Ctr, Los Angeles, CA
*Purpose: Highly sensitized (HS) patients are at an increased risk for chronic antibody mediated rejection (cABMR) and graft loss due to persistent, deleterious DSA production.…

Incidence and Effects of Posttransplant Herpes Zoster in Adult Solid Organ Transplant Recipients : A Meta-Analysis
S. H. Han, D. Kwon
Yonsei University Health System, Seoul, Korea, Republic of
*Purpose: Recently, non-live recombinant subunit HZ vaccine showed highly effective for herpes zoster (HZ) in hematopoietic stem cell transplantation. Several observational studies reported various features…

K. Joyal, T. Vanhove, B. Schreiber, M. Cote, S. Shao, N. Elias, H. Gilligan, K. Safa, E. Heher, W. Williams, C. Rogers
Massachusetts General Hospital Transplant Center, Boston, MA
*Purpose: Use of anti-thymocyte globulin (rabbit) (rATG) induction with belatacept/mycophenolate (MPA)/prednisone based immunosuppression (IS) has led to a reduction in rejection compared to that seen…
