Transplant Glomerulopathy in a Novel Model of Chronic Antibody Mediated Rejection Is Associated With DSA and Glomerular IgM
PurposeChronic active antibody mediated rejection (cAMR) and transplant glomerulopathy (TG) are major determinants of long-term allograft survival. However, the contribution of DSA and glomerular immunoglobulins…2015 American Transplant Congress
Distinct Subtypes of Rejection in a Novel Non Human Primate Model of Sensitization
[Background] Preformed and newly formed alloantibody post transplantation (TX) can significantly deteriorate graft survival. Patterns of humoral rejection in sensitized patients varies significantly due to…2015 American Transplant Congress
Reduction of Tacrolimus With Everolimus Addition in Maintenance Immunosuppression Improves Calcineurin Inhibitor-Induced Arteriolopathy in Kidney Allografts
Objectives: Although conversion of calcineurin inhibitor (CNI)-based immunosuppression to everolimus (EVR) has been shown to improve graft function, no histopathological evidence has been reported. The…2015 American Transplant Congress
A Prospective Study of Renal Function and Histological Changes in Renal Transplant Recipients With Acute Clinical and Subclinical Rejection
Background: To study the impact on renal function and histological changes in patients(pts) with acute clinical rejection(ACR) and subclinical rejection(SCR) from 3 to 12 month(m)…2015 American Transplant Congress
Association Between Histological Abnormalities in Time-Zero Renal Biopsies and Post-Donation eGFR in Live Donors
Time-zero biopsies (T0-RBx) of live-donor kidneys may reveal histological abnormalities at the time of organ recovery. The association between T0-RBx and subsequent kidney function in…2015 American Transplant Congress
Deceased Donor and Class II Donor Specific Antibody Predict Interface Activity While Increased Age at Time of Biopsy Predicts Fibrosis in Long-Term Pediatric Liver Allografts With Normal Liver Tests: iWITH Clinical Trial
Background: Although multiple single centers have reported deterioration of pediatric liver grafts in the face of normal liver tests, neither risk nor mechanism is understood.Methods:…2015 American Transplant Congress
IL-21 Regulates Creation of Tertiary Lymphoid Organs in Chronic Allograft Rejection
BACKGROUND: IL-21 is a cytokine expressed almost exclusively by cells of the adaptive immune system. This makes it an attractive target for reducing chronic allograft…2015 American Transplant Congress
A Clinical Signature Surrogate of Histological Lesions to Avoid Unnecessary One Year Surveillance Biopsy After Renal Transplantation
Introduction:Surveillance biopsy remains debated after renal transplantation since the histological diagnostic do not lead to clear therapeutic recommendations. The main objective for this study was…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
Post-Transplant Recurrence of Calcium Oxalate Crystals in Primary Hyperoxaluria Type 1 Detected by Surveillance Biopsies: Incidence, Risk Factors, and Effect on Graft Function
Background: Primary hyperoxaluria type 1 (PH1) is a rare metabolic defect that results in oxalate over-production by the liver and leads to renal disease due…
