UVB-induced depletion of donor-derived dendritic cells prevents allograft rejection of immune-privileged hair follicles in humanized mice.

Am J Transplant 2018 Nov 30. Epub 2018 Nov 30.

Department of Dermatology, Seoul National University College of Medicine, Seoul, Korea.

Dendritic cells (DCs) are key targets for immunity and tolerance induction; they present donor antigens to recipient T cells by donor- and recipient-derived pathways. Donor-derived DCs, which are critical during the acute posttransplantation period, can be depleted in graft tissue by forced migration via UVB irradiation. Here, we investigated the tolerogenic potential of donor-derived DC depletion through in vivo and ex vivo UVB preirradiation (UV) combined with injection of anti-CD154 Ab into recipients in an MHC-mismatched hair follicle (HF) allograft model in humanized mice.

Lymphocyte depletion and risk of acute rejection in renal transplant recipients at increased risk for delayed graft function.

Am J Transplant 2018 Sep 1. Epub 2018 Sep 1.

East Carolina University, Greenville, NC, USA.

Delayed graft function (DGF) is a risk factor for acute rejection (AR) in renal transplant recipients, and KDIGO guidelines suggest use of lymphocyte-depletion induction when DGF is anticipated. We analyzed the United Network for Organ Sharing/Organ Procurement and Transplantation Network (UNOS/OPTN) database to assess the impact of induction immunosuppression on the risk of AR in deceased kidney recipients based on pretransplant risk of DGF using a validated model. Recipients were categorized into 4 groups based upon the induction immunosuppression: (1) Rabbit anti-thymocyte globulin (rATG); (2) Alemtuzumab (C1H); (3) IL2-receptor antagonists (IL2-RA; basiliximab or daclizumab), and (4) No antibody induction.

Multimodal safety assessment of measles-mumps-rubella vaccination after pediatric liver transplantation.

Am J Transplant 2018 Sep 1. Epub 2018 Sep 1.

Department of Pediatrics, Division of General Pediatrics, Children's Hospital, Geneva University Hospitals and Faculty of Medicine, Geneva, Switzerland.

Live-attenuated vaccines are currently contraindicated in solid-organ transplant recipients. However, the risk of vaccine-preventable infections is lifelong, and can be particularly severe after transplantation. In this prospective interventional national cohort study, 44 pediatric liver transplant recipients with measles IgG antibodies <150 IU/L (below seroprotection threshold) received measles-mumps-rubella vaccine (MMR) at a median of 6.

Subclinical Changes in Deceased Donor Kidney Proteomes are Associated with 12-month Allograft Function Posttransplantation - a Preliminary Study.

Transplantation 2018 Sep 11. Epub 2018 Sep 11.

Nuffield Department of Surgical Sciences, University of Oxford, OX3 7LJ, UK.

Background: Cerebral injury during Donation after Brain Death (DBD) may induce systemic damage affecting long-term kidney function posttransplantation. Conventional evaluation of donor organ quality as a triage for transplantation is of limited utility.

Methods: We compared donor kidneys yielding opposing extremes of the continuum of posttransplantation outcomes by several common kidney biopsy evaluation techniques including Kidney Donor Profile Index (KDPI) and Remuzzi scoring, and analysed tissue from a minimal sample cohort using Label-Free Quantitation (LFQ) mass spectrometry.

Obesity and Metabolic Syndrome in Kidney Transplantation: The Role of Dietary Fructose and Systemic Endotoxemia.

Transplantation 2018 Aug 20. Epub 2018 Aug 20.

Department of Nephrology & Kidney Transplantation, Area 5, Level 7, Queen Elizabeth Hospital Birmingham, Mindelsohn Way, Edgbaston, Birmingham B15 2WB, UK.

Background: The concepts that obesity is merely a consequence of overeating, and that metabolic health then reflects obesity, may be insufficient and potentially flawed. The role of fructose intake and metabolic endotoxemia have gained attention recently, but data in kidney transplantation are lacking. This study evaluated the risk factors for metabolic syndrome (MS), its components, and other associated markers in kidney transplant recipients (KTRs), focussing particularly on fructose intake and systemic endotoxemia.

Protocol Duodenal Graft Biopsies Aid Pancreas Graft Surveillance.

Transplantation 2018 Aug 15. Epub 2018 Aug 15.

Department of Kidney & Pancreas Transplant Nephrology, Organ Transplant Centre, King Faisal Specialist Hospital and Research Centre, Riyadh, Kingdom of Saudi Arabia.

Background: Histological evaluation of the pancreas graft is usually done on demand resulting in significant delays. This analysis reports on endoscopic protocol duodenal graft biopsies at regular intervals to determine feasibility, safety and monitoring benefits.

Methods: Protocol duodenal graft biopsies in 27 18 consecutive pancreas transplants (10 simultaneous pancreas kidney [SPK], 17 pancreas after kidney [PAK]) with a follow-up of a minimum of 12 months were performed at days 14, 30, 90, 180, 360, 430. Read More

Determination of viremia cut-off for risk to develop BKPyV-associated nephropathy among kidney transplant recipients.

Transpl Infect Dis 2018 Oct 3;20(5):e12969. Epub 2018 Sep 3.

Department of Infectious Diseases, Hospital das Clínicas da Faculdade de Medicina da, Universidade de São Paulo, São Paulo, Brazil.

Background: BK polyomavirus (BKPyV)-associated nephropathy (BKPyVAN) is a consequence of BKPyV replication in the urinary tract in kidney transplant recipients (KTR).

Objectives: The objectives were to determine the prevalence of BKPyV replication and BKPyVAN, risk factors associated to sustained viremia and BKPyVAN, and viremia cut-off that best predict the occurrence of sustained viremia and nephropathy in KTR of a single University Hospital Kidney Transplant Center.

Patients And Methods: All KTR undergoing transplantation from August 2010 to December 2011 were enrolled and monitored up to 2 years posttransplantation for BKPyV viruria by decoy cells shedding or polymerase chain reaction (PCR) and viremia by PCR. Read More
