Borderline Changes in Kidney Allografts Represents a Non-Homogenous Cohort with Different Outcome
*Purpose: Borderline changes (BL) represent a frequent histological finding in kidney allograft with unclear prognosis.*Methods: In this single center, retrospective, observational study, the BL were…2019 American Transplant Congress
Is HLA Donor-Specific Antibody (DSA)-C3d+ Assay a Potential Predictor of Subclinical Antibody Mediated Damage in the Renal Graft?
*Purpose: The Aim of the study was to explore the predictive value of the C3d assay for tissue damage in kidney transplant recipients (KTR) in…2019 American Transplant Congress
Single Cell Sequencing of Human Kidney Allograft
1Weill Cornell Medicine, New York, NY, 2Rockefeller University, New York, NY
*Purpose: Transcriptome-based clustering of individual cells within the kidney allograft may help identify cell type-specific injury and has the potential to redefine the current histopathology-based…2019 American Transplant Congress
Proteomics Reveals Compartment-Specific Alterations in the Extracellular Matrix of Kidney Allografts with Antibody-Mediated Rejection
*Purpose: Antibody-mediated rejection (AMR) is the most important cause of premature kidney graft loss. AMR is caused by anti-HLA and non-HLA antibodies against proteins in…2019 American Transplant Congress
Post-Reperfusion Hepatic Beta-Catenin Activation Regulates Graft Damage, Inflammatory Responses and Transplant Outcomes
Dumont-UCLA Transplant Center, UCLA, Los Angeles, CA
*Purpose: Hepatic ischemia-reperfusion injury (IRI), an innate-immune driven hepatic inflammation response, represents a major risk factor of early allograft dysfunction (EAD) and rejection in liver…2019 American Transplant Congress
First UK Experience of the Molecular Microscope (MMDX™) in the Kidney Transplant Clinic
*Purpose: Molecular diagnostic methods are now included in the Banff classification of kidney transplant pathology. Traditional histopathology may be limited by intra/inter pathologist variation. The…2019 American Transplant Congress
Subclinical Rejection is Common on Surveillance Biopsies in Children with Kidney Transplant
*Purpose: Surveillance biopsies provide the opportunity to identify subclinical rejection and other pathologic changes, yet their utilization varies across pediatric kidney transplant centers. The purpose…2019 American Transplant Congress
High Prevalence of De Novo Donor-Specific Antibodies during Rejection after Liver Transplantation
Liver Transplant Unit, Hospital Clinic Barcelona, Barcelona, Spain
*Purpose: Anti-HLA donor specific antibodies (dnDSA) after liver transplantation (LT) are currently under investigation. Recent studies show an incidence of dnDSA after LT ranging from…2019 American Transplant Congress
The Safety of Surveillance and Indication Biopsies in Kidney Transplantation: A Series of 2000 Biopsies
*Purpose: Kidney biopsy (KB) remains the most important diagnostic tool in kidney transplantation. Despite its value, surveillance KB are not routinely done at majority of…2019 American Transplant Congress
A Potential Role for IgE-Mediated Immune Response in the Pathogenesis of Chronic Antibody-Mediated Rejection
*Purpose: Chronic antibody-mediated rejection (CAMR) is the main cause of graft loss and shares with systemic lupus erythematosus (SLE) the antibody-mediated kidney damage and the…
