Long Term Outcomes of Tocilizumab Therapy for DSA+ Antibody Mediated Rejection (ABMR) Resistant to IVIG + Rituxan (I+R) Treatment
Intro: Limited options are available for treatment of ABMR in highly-HLA sensitized patients (HS). Treatment options include I+R, PLEX+I+/- R, C5-inhibitor & bortezomib. Approximately 25%…2015 American Transplant Congress
Should Current IVIg Preparations Containing High Titers of Anti-HLA-I/-II IgG be Used for Lowering the Anti-HLA IgG in Sensitized Pre-Transplant Patients and Allograft Recipients?
HLA antibodies, Terasaki Foundation Laboratory, Los Angeles, CA.
Sera of non-alloimmunized individuals contain anti-HLA-I & -II IgG. Therefore it is reasonable expect HLA-I/-II reactivity of Intravenous Immunoglobulin (IVIg). However, the titers at which…2015 American Transplant Congress
Clinical and Immunologic Risk Factors Associated With Donor-Specific Antibody (DSA) Formation Following Renal Transplantation
Background: De novo DSA formation is emerging as an important risk factor for adverse graft outcomes following renal transplantation. Specific pretransplant risk factors for DSA…2015 American Transplant Congress
Evaluation of Preformed Anti-HLA Antibody of "Unknown Origin" after Kidney Transplant in a Brazilian Center
Background: The use of single antigen beads assay (SAFB) for the detection of anti-HLA antibodies (Abs) may reveal the presence of Abs in individuals without…2015 American Transplant Congress
Post Transplant De Novo Donor Specific Antibodies Correlate With the Development of Bronchiolitis Obliterans Syndrome Following Pediatric Lung Transplantation
Texas Children's Hospital, Houston, TX; Baylor College of Medicine, Houston, TX.
HLA donor specific antibodies (DSA) have been associated with poor allograft survival following adult solid organ transplantation (Tx). However, there is little evidence implicating post-Tx…2015 American Transplant Congress
Correlation Between C3d-Binding De Novo Donor Specific HLA Antibodies and Rejection in Kidney Transplant Recipients
Comprehensive Transplant Center, Northwestern University, Chicago, IL.
Donor specific antibodies (DSA) directed against HLA arising de novo post-kidney transplant are a major cause of graft loss, termed antibody mediated rejection (AMR). Currently,…2015 American Transplant Congress
A Distinct Glomerular Complement Deposition Pattern in Transplant Glomerulopathy
University of Minnesota, Minneapolis.
While many patients with transplant glomerulopathy (TG) have donor-specific antibodies, the lack of C4d deposition in the peritubular capillaries (ptc-C4d) in some cases has caused…2015 American Transplant Congress
Does Switching Predict Conversion: IgM De Novo Donor Specific HLA Antibodies Class Switch to IgG in Subclinical Antibody Mediated Rejection in Heart Transplant Recipients
1Cleveland Clinic, Cleveland; 2School of Medicine, Leipzig University, Leipzig, Germany.
Background: Concomitant C4d and C3d detection in heart biopsies correlates with circulating DSA and graft dysfunction. Detection of C4d only in surveillance biopsies is not…2015 American Transplant Congress
Assessment of IgG Subclass Significance for Early Graft Rejection and Long-Term Survival in HLA-Antibody Incompatible Renal Transplantation: Multivariate Approach
Donor HLA specific antibodies (DSA) can cause acute rejection and graft lost after renal transplantation. However neither the damaging antibody types, nor their acceptable levels…2015 American Transplant Congress
Antibodies Directed Against HLA-DQ Are Significantly Associated to Complement Activation In Vitro
Background: C1q-binding HLA antibodies (HLAabs) have been related to acute rejection and long-term graft loss. The characteristics of these antibodies and factors associated to complement…
