BACKGROUND: Cytomegalovirus (CMV) has a role in chronic rejection and graft loss in kidney transplant (KTx) and lung transplant (LTx) recipients. In addition, donor CMV seropositivity is an independent risk factor for renal graft loss. The anti-CMV response might modulate this risk. Expression of programmed cell death 1 (PD-1), a receptor involved in viral-specific T-cell exhaustion, is influenced by a single nucleotide polymorphism called PD-1.3 (wild-type allele G, variant allele A)...

BACKGROUND: Causes of "true" late kidney allograft failure remain unclear as study selection bias and limited follow-up risk incomplete representation of the spectrum. METHODS: We evaluated all unselected graft failures from 2008-2014 (n = 171; 0-36 years post-transplantation) by contemporary classification of indication biopsies "proximate" to failure, DSA assessment, clinical and biochemical data. RESULTS: The spectrum of graft failure changed markedly depending on the timing of allograft failure...

BACKGROUND: Heat shock protein 90 (HSP90), a molecular chaperone associated with the activation of client proteins, was recently reported to play an important role in immunologic reactions. To date, the role of HSP90 in solid organ transplantations has remained unknown. The aim of this study was to evaluate the relationship between serum HSP90α levels and acute allograft rejection after organ and tissue transplantation using serum samples from kidney allograft recipients, an in vitro antibody-mediated rejection model, and a murine skin transplantation...

BACKGROUND: Amyloid A (AA) amyloidosis is a multisystemic, progressive, and severe disease. Renal involvement is a prominent feature of the disease, and the outcome of patients on dialysis is poor. We aimed to analyze the outcomes of kidney transplantation in patients with AA amyloidosis in comparison with chronic glomerulonephritis (CGN). METHODS: Charts of patients who underwent kidney transplantation between 1988 and 2012 were reviewed; 41 patients with AA amyloidosis were identified, and 41 age- and sex-matched control patients with chronic CGN were included...

BACKGROUND: Recent studies suggest that the combination of tacrolimus (TAC) and everolimus (EVL) could become a viable option for use as standard maintenance immunosuppression in non-highly sensitized kidney transplant recipients. METHODS: We conducted a single-center, open-label, randomized pilot trial comparing two maintenance immunosuppression regimens in non-highly sensitized, adult, primary kidney transplant recipients: (TAC/EVL, Group A) vs our standard maintenance regimen of TAC plus enteric-coated mycophenolate mofetil (TAC/EC-MPS, Group B)...

Although kidney transplantation remains the best treatment for end-stage renal failure, it is limited by chronic humoral aggression of the graft vasculature by donor-specific antibodies (DSAs). The complement-independent mechanisms that lead to the antibody-mediated rejection (ABMR) of kidney allografts remain poorly understood. Increasing lines of evidence have revealed the relevance of natural killer (NK) cells as innate immune effectors of antibody-dependent cellular cytotoxicity (ADCC), but few studies have investigated their alloreactive potential in the context of solid organ transplantation...

Kidney transplantation after liver transplantation (KALT) offers longer survival and a better quality of life to liver transplantation recipients who develop chronic renal failure. This article aimed to discuss the efficacy and safety of KALT compared with other treatments. The medical records of 5 patients who had undergone KALT were retrospectively studied, together with a literature review of studies. Three of them developed chronic renal failure after liver transplantation because of calcineurin inhibitor (CNI)-induced nephrotoxicity, while the others had lupus nephritis or non-CNI drug-induced nephrotoxicity...

BACKGROUND: The epidemic of obesity has led to dilemmas facing all nephrologists who care for patients with chronic kidney disease and who must make decisions regarding whether or not the patient can undergo transplantation. The aim of the study was to assess the outcome of transplantation among obese compared to nonobese recipients. To minimize donor variability and bias, paired kidney analysis was applied. MATERIALS AND METHODS: Patients with a body mass index >30 who received transplants in our unit between January 2000 and December 2010 were selected...

Chronic transplant dysfunction (CTD) is the primary cause of late allograft loss in kidney transplantation. Indoleamine 2,3-dioxygenase (IDO) is involved in fetomaternal tolerance and gene therapy with IDO inhibits acute rejection following kidney transplantation. The aim of this study is to investigate whether gene therapy with IDO is able to attenuate CTD. Transplantation was performed in a rat Dark-Agouti to Wistar-Furth CTD model. Donor kidneys were incubated either with an adenovirus carrying IDO gene, a control adenovirus or saline...

Transplant patients are at increased risk for developing severe norovirus (NoV) infections with secondary complications such as rejection episodes and acute transplant failure. This single-center retrospective study included all kidney transplant patients tested positive for NoV RNA between January 2007 and December 2011. Data were compared to a control group of 528 kidney transplant patients without NoV infection. Sixty-five kidney transplant patients were recorded NoV RNA positive. Of these, 26 patients (40%) presented with acute transplant failure (AKI)...

The once-daily prolonged-release formulation of tacrolimus has been recently related with significant graft and patient mid-term survival advantages; however, practical information on the de novo administration after liver transplantation and longterm outcomes is currently lacking. This study is a 5-year retrospective analysis of a single-center cohort of liver transplant recipients treated de novo with once-daily tacrolimus (April 2008/August 2011). The study cohort consisted of 160 patients, including 23 with pretransplant renal dysfunction, with a median follow-up of 57...

BACKGROUND One-year renal function after kidney transplantation (KT) classified by the Kidney Disease: Improving Global Outcomes (KDIGO) chronic kidney disease (CKD) staging has been reported to be associated with graft survival. However, the outcomes of KT are improving. Therefore, the distribution and prognostic value of 1-year estimated glomerular filtration rate (eGFR) in recently performed transplants were re-evaluated in this study. MATERIAL AND METHODS We reviewed all patients who received KT between 2008 and 2011 at our institution, and followed them until June 2015...

PURPOSE OF THE REPORT: F-FDG PET/CT has been recently proposed as a noninvasive tool for the diagnosis of renal allograft acute rejection (AR) in kidney transplant recipients (KTRs). Still, the influence of kidney function on F-FDG uptake by renal grafts remains unknown. PATIENTS AND METHODS: We retrospectively identified all KTRs who underwent at least one F-FDG PET/CT. Kidney transplant recipients with documented pyelonephritis or AR were excluded. Estimated glomerular filtration rate (eGFR) was assessed using chronic kidney disease (CKD)-EPI equation...

UNLABELLED: Renal transplant is the best treatment for patients with chronical kidney disease however acute graft rejection is the major impediment to success in renal transplantation leading to loss of the organ the first year after transplantation. The aim of this study was to identify plasma proteins that may be early biomarkers of acute rejection of renal allograft, developing a diagnostic model that avoids the loss of the transplanted organ. Shotgun proteomics (LC-MS/MS) method was used to analyze a set of thirty-one plasma samples, including 06 from patients with acute graft rejection after transplantation (rejection group/Rej-group) and twenty-five from renal transplant patients with stable renal graft function (control group/Ct-group)...

Renal transplant candidates present immune dysregulation, caused by chronic uremia. The aim of the study was to investigate whether pretransplant peripheral blood gene expression of immune factors affects clinical outcome of renal allograft recipients. Methods. In a prospective study, we analyzed pretransplant peripheral blood gene expression in87 renal transplant candidates with real-time PCR on custom-designed low density arrays (TaqMan). Results. Immediate posttransplant graft function (14-day GFR) was influenced negatively by TGFB1 (P = 0...

BACKGROUND: The Banff classification is used worldwide to characterize pathological findings in renal allograft biopsies. During the 11th Banff meeting, relevant changes were introduced in the diagnostic criteria for Category 2 antibody-mediated rejection (ABMR). Here, we assess the effect of these changes on the diagnosis of late chronic ABMR. METHODS: Seventy-three indication renal graft biopsies (chronic dysfunction, proteinuria and/or the presence of de novo donor-specific antibodies) from 68 kidney transplant recipients initially classified following the Banff 2009 criteria were reviewed and reclassified as per the new Banff 2013 criteria...
