Background: Kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) are promising biomarkers for monitoring delayed graft function (DGF) after kidney transplantation. Here we investigated localization and distribution of KIM-1 and NGAL staining in renal allograft biopsies and studied their association with histological features, functional DGF (fDGF) and the tubular function slope (TFS), a functioning proximal tubular epithelial cell (PTEC) marker. Methods: Day 10 protocol biopsies of 64 donation after circulatory death recipients were stained for KIM-1 and NGAL and the positive area was quantified using ImageJ software...

PURPOSE OF REVIEW: The increasing reliance on marginal donors has driven research to investigate ways to repair and improve the quality of kidneys for transplantation. Normothermic perfusion technologies provide an opportunity for improved preservation, organ assessment and resuscitation/repair of damaged kidneys. This review describes the evolution of normothermic perfusion in kidney transplantation in the United Kingdom. RECENT FINDINGS: One hour of normothermic perfusion can be used to restore function and improve early graft function of extended criteria donor kidneys...

Maxillary sinus lift surgery (MSLS) is considered to be a useful treatment method for patients with atrophic alveolar bone. Choosing a suitable surgical procedure to simultaneously decrease graft absorption and obtain long-term survival of dental implants is still a challenge. In this study, 20 patients received MSLS with graft of bone morphogenetic protein 2 (BMP2)-loaded calcium phosphate. Dental implants were placed simultaneously in 10 patients receiving MSLS (1-stage group), and in 10 patients receiving dental implants with a 3 to 6 months delay (2-stage group)...

OBJECTIVES AND METHODS: The Furosemide Stress Test (FST) is a novel dynamic assessment of tubular function that has been shown in preliminary studies to predict patients who will progress to advanced stage acute kidney injury, including those who receive renal replacement therapy (RRT). The aim of this study is to investigate if the urinary response to a single intraoperative dose of intravenous furosemide predicts delayed graft function (DGF) in patients undergoing deceased donor kidney transplant...

Regenerative cell therapy is a promising therapeutic strategy in neurology, most notably to improve stroke recovery. Although tolerability and feasibility have apparently been validated, many questions remain as to what is the best type of cells to use, the best route and the post-stroke delay for administration. Two main strategies have currently emerged: intravenous injection of mesenchymal stem cells with systemic trophic support; and intracerebral grafting of neural stem cells with brain repair effects at the lesion site...

A previous donor intervention trial found that therapeutic hypothermia reduced delayed graft function (DGF) after kidney transplantation. This retrospective cohort study nested in the randomized dopamine trial (ClinicalTrials. gov identifier: NCT000115115) investigates the effects of spontaneous donor hypothermia (core body temperature <36°C) on initial kidney graft function, and evaluates five-year graft survival. Hypothermia assessed by a singular measurement in the ICU 4-20 hours before procurement was associated with less DGF after kidney transplantation (OR 0...

The case of a 39-year-old highly sensitized woman who underwent second renal transplantation after being on warfarin because of a history of frequent thromboses of her left femoral arteriovenous graft (AVG) is reported here. The patient received a flow cytometric positive crossmatch kidney transplant from a deceased donor. Her posttransplant course was complicated by prolonged delayed graft function (DGF) lasting for 9 months. Antibody-mediated rejection occurred in the immediate postoperative period. This resolved after treatment, and resolution was confirmed by repeat biopsy...

Renal ischemia-reperfusion injury (IRI), an inevitable event during kidney transplantation procedure, can result in delayed graft function or even primary nonfunction. In addition to strategies to limit IRI such as advancements in organ allocation systems and preservation of organs, and reduction in cold and warm ischemia time, remote ischemic conditioning (RIC) has attracted much attention in recent years. With promising findings and data suggesting a potential benefit of RIC in animal kidney transplantation models, a few clinical trials have investigated the use of RIC in human kidney transplantation...

INTRODUCTION: Orthotopic liver transplantation (OLT) has emerged as the mainstay of treatment for end-stage liver disease. In an attempt to improve the availability of donor allografts and reduce waiting list mortality, graft acceptance criteria were extended increasingly over the decades. The use of extended criteria donor (ECD) allografts is associated with a higher incidence of primary graft non-function and/or delayed graft function. As such, several strategies have been developed aiming at reconditioning poor quality ECD liver allografts...

To assess factors that influence the choice of induction regimen in contemporary kidney transplantation, we examined center-identified, national transplant registry data for 166,776 US recipients (2005-2014). Bi-level hierarchical models were constructed, wherein use of each regimen was compared pairwise with use of interleukin-2 receptor blocking antibodies (IL2rAb). Overall, 81.8% of patients received induction, including thymoglobulin (TMG, 46.0%), IL2rAb (21.9%), alemtuzumab (ALEM, 12.5%), and other agents (1...

BACKGROUND: Whether injury-related molecules in urines of individuals with ischemia-reperfusion injury (IRI) are independent predictors of graft outcomes and provide additional information compared with usual risk factors remains to be established. METHODS: We explored a cohort of 244 kidney transplant recipients who systematically had a urine collection 10 days after transplantation. The injury-related markers kidney injury molecule-1 (KIM-1) and angiogenin (ANG) levels in urines were measured...

CONTEXT: The use of aspirin in chronic kidney disease (CKD) patients has been shown to reduce myocardial infarction but may increase major bleeding. However, its effects in kidney transplant recipients are unclear. EVIDENCE ACQUISITIONS: A literature search was performed using MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews from inception through September 2016. We included studies that reported odd ratios, relative risks or hazard ratios comparing outcomes of aspirin use in kidney transplant recipients...

Delayed graft function (DGF) is very high in our center (70-80%), we usually receive a kidney for transplant after more than 22 hours of static cold ischemia time (CIT). Also, there is an inadequate care of the donors contributing to a high rate of delayed graft function (DGF). We decided to test whether machine perfusion (MP) after a cold ischemic time (CIT) improved the outcome of our transplant patients. We analyzed the incidence of DGF, its duration and the length of hospital stay (LOS) in patients who received a kidney preserved with MP after a CIT (Hybrid Perfusion - HP)...

Clinical observations that kidney transplant recipients receiving belatacept who experienced T cell-mediated acute rejection can be successfully treated and subsequently maintained on belatacept-based immunosuppression suggest that belatacept is able to control memory T cells. We recently reported that treatment with CTLA4-Ig from day 6 posttransplantation successfully rescues allografts from acute rejection in a BALB/c to C57BL/6 heart transplant model, in part, by abolishing B cell germinal centers and reducing alloantibody titers...

End-stage renal disease in the human immunodeficiency virus-positive population is increasing. Kidney transplant is the optimal therapy for this population rather than dialysis modalities if some criteria are met. These include undetectable plasma human immunodeficiency virus RNA, CD4 cell count over 200 cells/μL, and the absence of any AIDS-defining illness. Here, we describe the first living-donor kidney transplant in a human immunodeficiency virus-positive recipient in Turkey. The patient, a 52-year-old male diagnosed as human immunodeficiency virus positive, was on antiretroviral therapy, which consisted of 400 mg twice daily darunavir, 100 mg/day ritonavir, and 50 mg/day dolutegravir...
