DNA Methylation Classifier Associates With Long-Term Graft Function Post-Kidney Transplantation
1UVA, Charlottesville, VA; 2VCU, Richmond, VA; 3Noerthwestern University, Chicago, IL.
"Background. Late graft failure is a major problem after kidney transplantation (KT) mainly due to chronic renal allograft dysfunction (CRAD). Data about common pathways of…2015 American Transplant Congress
Urinary Cell-Free DNA Is a Sensitive Marker of Early Renal Transplant Injury
Surgery, UC San Francisco, San Francisco, CA.
Introduction:Circulating donor-derived cell-free DNA (dd-cfDNA) has been reported as a surrogate of transplant injury in the blood but requires expensive donor and recipient DNA sequencing.Method:…2015 American Transplant Congress
Biomarker for Calcineurin Inhibitors Nephrotoxicity in Solid Organ Transplantation: Validation of a Urine Gene Expression Panel
Background: We previously described a gene expression signature as biomarker of calcineurin inhibitor nephrotoxicity (CNIT) post renal transplantation. Herein, we aimed to validate the same…2015 American Transplant Congress
Early Detection of HCC Mutations in Indeterminate Lesions Using Liquid Biopsies
Background Recent sequencing efforts have characterized the mutation profile of hepatocellular carcinoma (HCC); however, the relevance to clinical decision-making has been limited by the infrequency…2015 American Transplant Congress
Validation of a Peripheral Blood Gene Expression Profile for SubClinical Acute Rejection in Kidney Transplant Recipients Findings from the CTOT 08 Study
1Northwestern University, Chicago; 2Scripps Research Institute, La Jolla.
Background: Sub-clinical acute rejection (SCAR) is histologic acute cellular rejection in the presence of a normal/stable serum creatinine, and is associated with worse graft survival.…2015 American Transplant Congress
Non-Invasive Panel of MicroRNAs Predict Long-Term Outcomes Post-Kidney Transplantation
1Surgery and Pathology, UVA, Charlottesville, VA; 2VCU, Richmond, VA.
Background. Currently available methods for evaluating kidney graft function post-transplantation (KT) are either ineffective or inaccurate (e.g., serum creatinine) or highly invasive (e.g., biopsies). We…2015 American Transplant Congress
Plasma 4β-Hydroxycholesterol Measurement as a Potential Biomarker for CYP3A5 Activity in Informing Tacrolimus Dosing
BackgroundRecently, 4β-hydroxycholesterol (4β-OHC) has been shown to be an endogenous marker of P450 3A activity in clinical practice (Diczfalusy et al, 2011). 4β-OHC concentration increases…2015 American Transplant Congress
APOL1 High-Risk Genotype in African American Live Kidney Donors Is Not Associated With Post-Donation Development of Hypertension and Kidney Disease
African Americans (AA) with two apolipoprotein L1 (APOL1) risk alleles have more kidney disease than compared to those with one or zero risk alleles. A…2015 American Transplant Congress
Correlation of Longitudinal Gene-Expression Profiling Score to Cytomegalovirus Infection: Results from the Outcomes AlloMap® Registry
Purpose: Cytomegalovirus (CMV) infection has been implicated in the pathogenesis of allograft rejection, which is reflected by high gene-expression profiling (GEP) scores. In the IMAGE…2015 American Transplant Congress
Plasma Levels of Donor-Derived Cell-Free DNA Increase With Rejection and Often Decrease After Treatment in Organ Transplant Recipients
1CareDx, Inc, Brisbane, CA; 2Cedars-Sinai Medical Center, Los Angeles, CA.
Purpose: Donor-derived cell-free DNA (dd-cfDNA) is a potential biomarker of acute cellular rejection (ACR) in organ transplant recipients. dd-cfDNA levels in longitudinal plasma samples from…
