Biopsy Characteristics of Kidneys from a Single Large OPO
1David Geffen School of Medicine, Los Angeles, CA, 2One Legacy, Los Angeles, CA
*Purpose: As deceased donor pool have expanded, kidney biopsy has been increasingly used to help determine organ suitability for transplant. There are concerns that biopsy…2022 American Transplant Congress
Top Molecules Associated with CLAD in Lung Transplants Are Shared Between Mucosal Biopsies, Transbronchial Biopsies, and Kidney Transplant Biopsies at Risk of Progression
*Purpose: Chronic lung allograft dysfunction (CLAD) is a physiologic state with grave consequences for progression to failure but cannot be diagnosed by biopsy histology. We…2022 American Transplant Congress
Prospective Study of Preimplantation Biopsy in Deceased Donor Kidney Transplantation (DDKT)
*Purpose: Our aim was to study the impact of preimplantation biopsy (Bx) findings in selecting kidneys from more marginal donors.*Methods: This is a 2-year prospective…2022 American Transplant Congress
Prospective Evaluation of Donor-Derived Cell-Free DNA (dd-cfDNA) in Monitoring Response to Anti-Rejection Treatment in Kidney Transplant Recipients with Indication Biopsy
*Purpose: Donor-derived cell-free DNA (dd-cfDNA) is a marker of allograft injury in kidney transplant recipients (KTR). Little is known about the possible use of dd-cfDNA…2022 American Transplant Congress
Evaluation of the Significance of Isolated C4d Staining without Histological Evidence of Rejection on Kidney Biopsies After ABO-Compatible Transplantation in Pediatric Recipients
*Purpose: C4d staining in peritubular capillaries has been part of ABMR Banff definition since 2003. Despite relatively high specificity, c4d staining shows limited sensitivity, and…2022 American Transplant Congress
Transbronchial Cryobiopsy vs Conventional Forceps Biopsy in Lung Transplant Recipients Multicenter Study
*Purpose: Transbronchial biopsy is considered the gold standard in the diagnosis of acute cellular rejection after lung transplantation. There still remains the discussion in conventional…2022 American Transplant Congress
Histopathology at Diagnosis and One-Year Outcomes in Antibody Mediated Rejection in Pediatric Kidney Transplant Recipients: Preliminary Findings from the Paramour “Pediatric Renal AMR Outcomes” Study
*Purpose: Antibody mediated rejection (AMR) is a major cause of kidney allograft dysfunction leading to graft loss. There is a paucity of data regarding how…2022 American Transplant Congress
Diagnostic Performance of Donor-Derived Cell-Free DNA Assay (AlloSure®) in Kidney Transplant Recipients with Graft Dysfunction: A Single Center Study
*Purpose: Circulating donor-derived cell-free DNA (dd-cf-DNA) is a non-invasive biomarker of kidney allograft injury with a high negative predictive value for ruling out active rejection…2022 American Transplant Congress
Deceased Donor Procurement Biopsy Practices, Interpretation, and Histology-Based Decision Making: A Survey of US Transplant Centers
*Purpose: In light of contemporary controversies on the utility of kidney procurement biopsies in predicting allograft outcomes and guiding organ acceptance, we surveyed transplant providers…2022 American Transplant Congress
Surveillance with Protocol Biopsies for Rejection Significantly Impacts Survival Following Intestine Transplant
*Purpose: Frequent surveillance biopsy is required on the first month post intestinal transplant(IT) due to high-risk of acute rejection. However, the utility and the frequency…
