INTRODUCTION: Nowadays, the number of patients receiving a second graft is growing, and the management of failed grafts is still controversial. OBJECTIVE: Our objective was to analyze the influence of graft nephrectomy on graft and patient survival. MATERIALS AND METHODS: We retrospectively evaluated the demographic features and graft outcomes of 63 recipients who received second allografts between August 1985 and April 2013. They were divided into two groups: group A, those who underwent nephrectomy of failed graft (n = 21, 33...

BACKGROUND: The systematic use of grafts from controlled donors after cardiac death (cDCD) started in our country in 2012 and expanded with the strategic support of National Transplant Organization. We present our experience in kidney transplantation with organs from cDCD donors with a mean follow-up of 3 years. METHODS: Observational prospective study of all transplants performed in our center in 2012-2013 followed to 2016. The immunosuppression protocols were triple therapy for low-risk recipients from a standard brain death donor (DBD), adding basiliximab or thymoglobulin induction for extended-criteria donor or high-risk recipient, respectively, and thymoglobulin induction plus triple therapy for all cDCD recipients...

BACKGROUND: The arterial resistive index, also referred to as the resistive index (RI) or Pourcelot Index, is a measure of pulsatile blood flow. Previous studies have demonstrated the usefulness of the RI as a predictor of allograft outcomes based on RI measurement in the later stages after transplantation. However, there is little evidence of the predictive value of "immediate" RI measurement within 24 hours after transplantation. METHODS: We performed a retrospective cohort study of 305 adult renal transplants carried out between 2003 and 2013...

Renal ischemia reperfusion (IR)-injury induces activation of innate immune response which sustains renal injury and contributes to the development of delayed graft function (DGF). Triggering receptor expressed on myeloid cells-1 (TREM-1) is a pro-inflammatory evolutionary conserved pattern recognition receptor expressed on a variety of innate immune cells. TREM-1 expression increases following acute and chronic renal injury. However, the function of TREM-1 in renal IR is still unclear. Here, we investigated expression and function of TREM-1 in a murine model of renal IR using different TREM-1 inhibitors: LP17, LR12 and TREM-1 fusion protein...

Richard N Formica
The kidney allocation system that took effect on December 4, 2014 represents a significant improvement over the prior approach. It seeks to improve outcomes by longevity matching - pairing kidneys expected to function the longest with recipients expected to live the longest. It addresses the biological barriers faced by highly sensitized patients in an evidence based fashion and it begins to introduce the concept of medical need into kidney allocation by crediting time from the starting dialysis to a patient's waiting time...

OBJECTIVES: Vascular complications, especially immediate events during kidney transplant, are the major cause of graft loss, and prompt surgical intervention is important for salvage of the graft and recipient. In this study, our aim was to show our experiences with vascular interventions and their effects on graft outcomes in transplant patients with suspected immediate vascular events. MATERIALS AND METHODS: Over 24 years (from 1990 to 2014), 2100 renal transplant procedures (1562 living and 538 deceased donors) were performed by one fixed team...

BACKGROUND: Proteinuria is a hallmark of glomerular injury, and persistent proteinuria is associated with graft failure in kidney transplant patients. Recently, it is known that the level of circulating angiopoietin-like 4 (ANGPTL4) is elevated in the patients with human nephrotic syndrome, in which ANGPTL4 is responsible for relieving proteinuria. PURPOSE: The purpose of this study is to determine effects of clinical factors and genetic polymorphism of ANGPTL4 on proteinuria after kidney transplantation...

The timely reconstitution and regain of function of a donor-derived immune system is of utmost importance for the recovery and long-term survival of patients after allogeneic hematopoietic stem cell transplantation (HSCT). Of note, new developments such as umbilical cord blood or haploidentical grafts were associated with prolonged immunodeficiency due to delayed immune reconstitution, raising the need for better understanding and enhancing the process of immune reconstitution and finding strategies to further optimize these transplant procedures...

BACKGROUND: Extracellular histones are cytotoxic molecules that are related to cell stress and death. They have been shown to play a crucial role in multiple pathophysiologic processes like sepsis, inflammation, vascular dysfunction and thrombosis. Their role in organ donation and graft function and survival is still unknown. The aim of this study was to assess whether an association exists between the presence of extracellular histones in machine perfusates and deceased donor kidney viability...

Previous studies on patient and allograft outcomes of obese kidney transplant recipients (KTRs) remain controversial. To what extent obesity-related comorbidities contribute to adverse outcomes, however, hasn't been addressed. We studied all KTRs from 2005 to 2012. 29 (4%), 317 (48%), 217 (33%), 76 (12%), and 21 KTRs (4%) were identified as underweight, normal-weight, overweight, obese, and morbid obese, respectively. 33 of 97 obese KTRs (34%) had pre-existent diabetes. Samples were collected before transplantation and at +1, +2, +3months posttransplantation...

INTRODUCTION: For the treatment of patients with end-stage renal disease, kidney transplantation is preferred to renal replacement modalities such as hemodialysis and peritoneal dialysis. Although open surgery remains the gold standard, minimally invasive approaches have recently been applied in transplant kidney surgery. Despite growing enthusiasm and potential benefits of robotic kidney transplant, many aspects of this novel technique remain controversial. Aim of this study was to analyze the current status and future developments in robotic-assisted surgery for kidney transplantation...

Batf3 is a transcription factor that impacts the development of CD103(+) tissue-resident dendritic cells (DCs). However, whether Batf3 is absolutely required for the development of CD8(+) DCs remains controversial. Id2 is required for CD8(+) DC development. Here we show that bone marrow chimeric mice with a deletion of Id2 in the CD11c compartment lose the ability to reject a skin graft expressing a non-self protein antigen or mount a delayed hypersensitivity response. In contrast, Batf3((-/-)) mice remained competent for skin graft rejection and delayed hypersensitivity, and retained a CD8(+) DC population with markers characteristic of the CD11b(+) DC lineage, including CD11b, CD4 and CD172α, as well as the key regulator transcription factor IRF4, but lacked IRF8 expression...

Smoking is associated with unfavourable outcome in solid organ transplant recipients. Nicotine may predispose to kidney injury by increasing oxidative stress. We hypothesized that former smoking negatively affects graft outcome in kidney transplant recipients and especially those with delayed graft function (DGF). We included adult recipients of a kidney transplant between January 1(st) 2003 and October 1(st) 2015 at Ghent University Hospital and recorded outcomes until October, 31(st) 2015. We used Kaplan-Meier and multivariable Cox proportional hazard analysis to examine the relationship between former smoking at the time of transplantation and the incidence of 10-year graft loss with and without censoring for death in 1013 participants...

AIM: To investigate whether the parameters of machine perfusion could predict the quality of kidneys from donation after circulatory death(DCD) donors and expanded criteria donors (ECD) . METHODS: 58 kidneys from DCD/ECD donors were harvested in our hospital from July 2011 to August 2014. All kidneys were preserved with machine perfusion(Life Port), and parameters of machine perfusion were collected. All kidneys were biopsied before transplantation. The primary endpoints were delayed graft function(DGF), graft loss and patient death...

The terminologies of "body size", "body mass index (BMI)", "body weight", "large BMI" and "obesity" are controversial for defining the effects of "adiposity" or "fat excess" on the outcomes of dialysis and transplant patients. However, probably these terminologies will be continued to be used in the future as well, because of being older and simpler terminologies. In the general population obesity is a powerful risk factor for cardiovascular morbidity and mortality, while, it conferred a survival advantage to dialysis patients...
