Age Difference between Donor and Recipient Predisposes to Early Interstitial Fibrosis and Tubular Atrophy in Pediatric Kidney Transplantation
Pediatric Nephrology, David Geffen School of Medicine at UCLA, Los Angeles, CA.
Introduction: Previous studies in adult kidney transplant recipients (KTRs) have shown that an increased age difference between donor and recipient increases the risk of arterial…2018 American Transplant Congress
Noninvasive Quantization of Intra-Renal Allograft C4d Deposition with Targeted Ultrasound Imaging
Antibody-mediated rejection (AMR) has emerged as the major cause of renal allograft dysfunction. C4d, a specific marker of AMR diagnosis, was strongly recommended for routine…2018 American Transplant Congress
Recombinant Relaxin Protects Liver Transplants from Ischemia-Reperfusion Damage via Hepatocyte Glucocorticoid Receptor: From Bench-to-Bedside
Hepatic ischemia-reperfusion injury (IRI) represents a major risk factor of early graft dysfunction and acute/chronic rejection as well as a key obstacle to expanding the…2018 American Transplant Congress
Eluates from Fine-Needle Allograft Biopsy Increase Donor-Specific Antibody Identification in Antibody Mediated Rejection
1University of Cincinnati, Cincinnati; 2Hoxworth Blood Center, Cincinnati.
Aim. Antibody mediated rejection (AMR) represents a risk for graft loss, and the presence of circulating donor-specific antibody (cDSA) is a major criterion for AMR…2018 American Transplant Congress
Influence of 6 Months Protocol Biopsies with and without Intervention on Course of GFR after Pediatric Renal Transplantation
Data on protocol biopsies in childhood are rare. We evaluated renal function in 86 children after kidney transplantation (KTX) who underwent a protocol biopsy 6…2018 American Transplant Congress
Serelaxin-Notch1 Signaling Promotes Macrophage M2 Differentiation and Alleviates Hepatocellular Damage in Orthotopic Liver Transplantation: From Mouse-to-Human
1Surgery, Liver Transplant, UCLA, Los Angeles, CA; 2Pathology, UCLA, Los Angeles, CA.
Background/Aim: We have documented crucial role of macrophage Notch1 signaling in a mouse warm hepatic ischemia-reperfusion injury (IRI) model. However, its clinical relevance or therapeutic…2018 American Transplant Congress
NK Cells in Allograft Kidney Biopsies during Rejection: Detection, Quantification, and Precise Localization Using Multiplex Immunofluorescence
Introduction: Among the complex cellular interplay engaged in renal rejection, recent transcriptomic analysis of renal biopsies has detected NK cell transcripts in the setting of…2018 American Transplant Congress
Distribution of Biopsy Proven Acute Rejection in a Large Pediatric Kidney Transplant Program: A Four Year Experience
Introduction: Kidney biopsy is the gold standard for diagnosing rejection, transplant glomerulopathy, and other pathology after transplantation. We aimed to understand the distribution of Banff…2018 American Transplant Congress
“Majority Rules”: A Method to Reduce Variability in Diagnosing Antibody Mediated Rejection in Renal Allograft Biopsies Using Banff 2013
1Mayo Clinic, Rochester, MN; 2Mayo Clinic, Scottsdale, AZ; 3Mayo Clinic, Jacksonville, FL.
Introduction: The Banff 2013 criteria for diagnosing antibody-mediated rejection (ABMR) includes three lesions: glomerulitis (g), peritubularitis (PTC), and chronic glomerulopathy (cg). The poor reproducibility of…2018 American Transplant Congress
Biopsy Correlates of DSA in Antibody-Mediated Rejection: C4d vs Microvascular Inflammation Scores
Icahn School of Medicine at Mount Sinai, New York, NY.
Background: The diagnosis of antibody-mediated rejection (AMR) requires the presence of both the histologic features of AMR as well as donor-specific antibodies (DSA). Whether anti-HLA…
