The Incidence of Polyomavirus-BK and Cytomegalovirus Infections in Renal Transplant Recipients Following Rituximab Administration
Northwestern Memorial Hospital, Chicago, IL.
Rituximab is an antibody that binds to the CD20 antigen on B cells resulting in rapid and prolonged depletion. At Northwestern Memorial Hospital, a single…2018 American Transplant Congress
Impact of De Novo DSA (DnDSA) on Outcomes in HLA-Sensitized (HS) Patients Transplanted after IVIG + Rituximab Desensitization (DES)
Introduction: Highly-HLA sensitized patients (HS) with donor specific antibodies (DSA) at transplant are at risk for Type 1 ABMR. However, the incidence of Type 2…2018 American Transplant Congress
TACI Polymorphisms Associated with Allograft Rejection in Mice and in Man
Trans-membrane Activator and CAML Interactor (TACI) controls B cell differentiation and memory and exists as numerous allelic variants in healthy individuals. In fact, TACI is…2018 American Transplant Congress
Prolonged Cold Ischemia Storage of Renal Allografts Shifts DSA Specificity and Enchances Glomerular Injury
Immunology, Cleveland Clinic, Cleveland, OH.
Prolonged cold ischemia storage (CIS) of donor organs is a major risk factor for acute and chronic graft injury. The goal of this study was…2018 American Transplant Congress
Elevated Levels of CD19+ B Cells before or after Rituximab Administration is a Risk Factor for the Early Rejection of a Living Kidney Transplant
1Nephrology, Ohkubo Hospital, Tokyo, Japan; 2Urology, Ohkubo Hospital, Tokyo, Japan.
[Introduction]Rituximab (RTX) is used for desensitization in highly sensitized patients, such as those undergoing ABO-incompatible (ABOi) kidney transplantation. Although RTX is generally effective, some patients…2018 American Transplant Congress
In Vivo Administration of Plerixafor and Bortezomib Results in Bone Marrow Plasma Cell Mobilization and Death While Inducing Biphasic Plasma Cell Apoptosis in Peripheral Blood
1U Cincinnati, Cincinnati; 2Cincinnati Children's, Cincinnati; 3Duke, Durham.
Bone marrow (BM) plasma cells (PC) secreting HLA antibody (Ab) remain a persistent reservoir of donor specific Ab and present a significant hurdle to allograft…2018 American Transplant Congress
Genomic Modifications Associated with Epstein Barr Virus+ Post-Transplant Lymphoproliferative Disorder
Epstein Barr Virus (EBV) is nearly ubiquitous in the human population, yet EBV infection is typically asymptomatic. Nevertheless, immunosuppressed transplant recipients are susceptible to EBV+…2018 American Transplant Congress
Pancreas Transplant for Type 2 Diabetes is Associated with Preserved Function, but Impaired Glucose Tolerance: A Comparative Analysis
Multi-Organ Transplant Program, Toronto General Hospital, Toronto, ON, Canada.
Background: The indications and outcomes of pancreas transplantation for type 2 diabetes mellitus (T2DM) remains controversial. The aim of this study was to compare the…2018 American Transplant Congress
Analysis of Circulating CD38+/CD138+ Plasma Cells during Development of De Novo Donor Specific Antibody Responses
CTC/Surgery, Cedars-Sinai Medical Center, Los Angeles, CA.
Purpose: Donor specific antibodies (DSA) that emerge following transplantation are indicative of allogenic sensitization and a predisposing factor for antibody mediated rejection. Though various methods…2018 American Transplant Congress
Pilot Study of Plasma Cell Niche-Targeted Therapy for Enhancement of Proteasome Inhibitor Effectiveness
1UCincinnati, Cincinnati; 2Cincinnati Children's, Cincinnati; 3Duke, Durham.
HLA antibody (Ab)-secreting bone marrow (BM) plasma cell (PC) survival depends on niche occupancy via a CXCR4 (PC)-CXCL12 (BM stromal cell) interaction. Plerixafor inhibits CXCR4-CXCL12…
