Implication of Intragraft γδ T Cell Profiles in Operational Tolerance After Clinical Transplantation of Highly Immunogenic Intestine -Difference from Immunoprivileged Liver
(Background) T-cell receptor (TCR) Vδ2 γ δ T cells (Vδ 2 cells) participate in host defense, whereas Vδ 1 γ δ T cells (Vδ 1…2015 American Transplant Congress
Tacrolimus for the Treatment of Refractory Biopsy-Proven Acute Cellular Rejection in Patients on Belatacept-Based, CNI- and Steroid-Free Immunosuppression Regimens
1Univ of Cincinnati, Cincinnati; 2The Christ Hospital, Cincinnati.
Background: Tacrolimus (TAC) is effective as rescue treatment (tx) in renal transplant patients (pts) on cyclosporine-based immunosuppression (IS) who have recurrent or resistant acute rejection…2015 American Transplant Congress
A Prospective Comparison of the Completeness of Donor Kidney Biopsies
1Transplantation, University of Maryland, Baltimore; 2Pathology, University of Maryland, Baltimore.
Background: The use of expanded criteria kidneys has plateaued, possibly due to inadequate pathologic evaluation or lack of a universal grading system. We examined pre-transplant…2015 American Transplant Congress
Late Antibody-Mediated Rejection in a Large Cross-Sectional Cohort of Kidney Transplant Recipients – Results of the Screening Phase of the BORTEJECT Study
Antibody-mediated rejection (ABMR) is well established to be a leading cause of graft failure. Here, we investigated the prevalence of late ABMR in a large…2015 American Transplant Congress
Reassessing Tubulitis and Interstitial Infiltrate: Creating a New Probabilistic Definition of TCMR
Alberta Transplant Applied Genomics Centre, Edmonton, Canada.
Conventional diagnosis of T cell-mediated rejection (TCMR) in kidney transplant biopsies relies on interstitial inflammation (i-lesions), tubulitis (t-lesions), vasculitis (v-lesions) and experience-derived interpretation rules. The…2015 American Transplant Congress
Clinicopathological Scenarios (CPS) Defined by Viremia, Creatinine and Histology in Polyomavirus Nephropathy Differ in 1st and 2nd (Follow-Up) Biopsy
Pathology and Medicine, University of Maryland School of Medicine, Baltimore, MD.
Studies of sequential kidney biopsies (KB) after the diagnosis of polyomavirus allograft nephropathy (PVN) are scarce and clinicopathological evolution of PVN poorly understood. In practice…2015 American Transplant Congress
The Impact of Therapy On the Inflammatory Infiltrate in Renal Allografts With Acute and Chronic Antibody Mediated Rejection
Little is known about the effect of usual treatment for acute and chronic antibody mediated rejection (aAMR and cAMR) on inflammatory cells within the allograft.…2015 American Transplant Congress
Treatment of Subclinical Rejection Identified On Surveillance Biopsy May Prevent the Development of Chronic Alloimmune Injury
Imperial College Kidney and Transplant Centre, Hammersmith Hospital, London, United Kingdom.
Surveillance biopsies [SBx] are not universally performed following renal transplantation. In patients in whom protocol biopsies are performed, how best to manage subclinical rejection [SCR]…2015 American Transplant Congress
A Comparative Analysis of Histological Scoring in Living Donor Renal Transplants from Donors Above and Below 60 Years of Age
BACKGROUND AND OBJECTIVES: World Health Organisation estimates that the absolute number of people aged 60yrs and over will increase from 605-million to 2-billion over the…2015 American Transplant Congress
The Impact of Microcirculation Inflammation in Predicting Treatment Response for Late Onset Antibody Mediated Rejection
BackgroundThere have been marked advances of immunosuppression. However, management of late onset antibody-mediated rejection (AMR) after 6 months is still challenging. Despite important diagnostic and…
