BACKGROUND: Thin basement membrane nephropathy (TBMN) is the most common cause of persistent glomerular hematuria. Most individuals with TBMN show a benign course, although it can be difficult to distinguish it from early stages of progressive renal diseases. However, only limited studies address the prognosis of donors with TBMN and their recipients. METHODS: From 2007 to 2016, 11 recipients received kidney grafts from donors with TBMN, and their clinical data were analyzed retrospectively...

BACKGROUND: Solid-organ transplants provide a second chance to thousands of critically ill patients with end-organ failure each year. Immunosuppressants are administered to patients to prevent graft rejection of a transplanted organ, such as a heart, kidney, or liver, while placing the recipient at greater risk for infection and cancer. OBJECTIVE: The literature provides evidence of various cancers that have been found to develop in patients' posttransplantation...

We evaluated the effect of resveratrol (RSV) on graft survival after islet transplantation (ITx) in diabetic mice. Isolated islets from Balb/c mice (200 IEQ) were transplanted under the kidney capsule of diabetic Balb/c mice. Vehicle or RSV (200 mg/kg/day, orally) was given for 14 days after ITx. Two more control groups [STZ-treated (No-ITx-Control) and STZ+RSV-treated (No-ITx-RSV) mice without ITx] were added. Glucose tolerance tests (GTT) was performed at 14 days after ITx. In vitro, isolated islets pretreated with vehicle or RSV (1 μM) were incubated in a hypoxic chamber (O2 1%, 1hr)...

AIM OF THE STUDY: Intestinal transplantation (IT) is a life-saving procedure for carefully selected patients with intestinal failure. We evaluated patients who had undergone simultaneous intestinal and kidney transplantation (SIKT) to determine whether UK guidelines for inclusion of a renal allograft (dialysis dependent or estimated glomerular filtration rate ((eGFR)) < 45 ml/min/1.73 m2) are justified. METHODS: A single centre analysis was undertaken of adults undergoing IT at the Cambridge Transplant Centre between December 2007 and January 2016...

The Kidney Allocation System (KAS) was implemented in December 2014 with unknown impact on the pediatric waitlist. To understand the effect of KAS on pediatric registrants, deceased donor kidney transplant (DDKT) rate was assessed using interrupted time series analysis and time-to-event analysis. Two allocation eras were defined with an intermediary washout period: Era 1 (01/01/2013-09/01/2014), Era 2 (09/01/2014-03/01/2015), and Era 3(03/01/2015-03/01/2017). When using Cox proportional hazards, there was no significant association between allocation era and DDKT likelihood as compared to Era 1 (Era 3: aHR: 1...

OBJECTIVE: The association between pre-transplant mental health concerns and non-adherence and post-transplant outcomes after kidney transplantation is not fully established. We examined the relationship between a pre-transplant history of mental health concerns and non-adherence and post-transplant outcomes among kidney transplant recipients. METHODS: In this retrospective single center cohort study of adult kidney transplant recipients (n=955) the associations between the history of mental health concerns or non-adherence and the time from kidney transplant to biopsy proven acute rejection; death-censored graft failure and total graft failure were examined using Cox proportional hazards models...

BACKGROUND: Transplantation is the preferred modality for renal replacement therapy in children. With increasing rates of re-transplantation within the paediatric population, there are more sensitised children on waiting lists. One issue with developing strategies to treat these children is the number of different definitions of sensitisation. and we would therefore recommend an immunological risk stratification approach. METHODS: We discuss methods of sensitisation prevention, assessment and management, including paired exchange programmes and desensitisation protocols...

Norway provides total social welfare coverage for organ transplantations, including free immunosuppressive medication and prepaid life-long follow up for both recipients and donors. Despite these benefits the proportion of living kidney donors (LKD) has in recent years declined from around 40% (2011) of all kidney transplantations to 24% (2016). This study suggests harnessing patient- and donor-narratives as a tool for addressing the current fall in donation rates. The hospital records of 18 recipient/donor dyads were compared with patient and donor accounts elicited in semi-structured interviews...

Extracellular ATP interacts with purinergic type 2 (P2) receptors and elicits many crucial biological functions. Extracellular ATP is sequentially hydrolyzed to ADP and AMP by the actions of defined nucleotidases, such as CD39, and AMP is converted to adenosine, largely by CD73, an ecto-5'-nucleotidase. Extracellular adenosine interacts with P1 receptors and often opposes the effects of P2 receptor activation. The balance between extracellular ATP and adenosine in the blood and extracellular fluid is regulated chiefly by the activities of CD39 and CD73, which constitute the CD39-adenosinergic axis...

Angiotensin II type 1 receptor (AT1R) antibody, a non-HLA antibody, has been found to have a detrimental effect on kidney allografts. Similarly to HLA antibodies, recipients who have AT1R antibodies are at risk for allograft rejection and poor long-term graft outcome. Besides mediating allograft rejections via direct effects on endothelial and vascular smooth muscle without complement activation, AT1R antibodies may lead to accelerated hypertension via the renin-angiotensin pathway. There has been no definite level of AT1R antibody that predicts allograft rejection...

BACKGROUND: Although a successful kidney transplant (KTx) improves most of the mineral and bone disorders (MBD) produced by chronic kidney disease (CKD), hyperparathyroidism may persist (pHPT). Current guidelines recommend parathyroidectomy if serum parathormone is persistently elevated 1 year after KTx, because pHPT has been recently associated with poor graft outcomes. However, whether patients with pHPT and adequate renal function are at risk for long-term graft failure is unknown...

OBJECTIVE: The objective of this study was to examine the association between tacrolimus concentration in oral fluids and in whole blood and to investigate the various factors that influence this relationship. PATIENTS AND METHODS: Forty-six adult kidney transplant recipients were included in the study. Study A (ten patients) included the collection of several paired oral fluid samples by passive drool over a 12-h post-dose period. Study B (36 patients) included the collection of oral fluids pre-dose and at 2 h after the tacrolimus dose under three conditions: un-stimulated, after stimulation with a tart candy, and after mouth rinsing...

The risks associated with transplanting HIV-positive kidneys into HIV-positive recipients have not been well studied. Since 2008, 43 kidneys from 25 HIV-positive deceased donors have been transplanted into patients who are HIV positive in Cape Town, South Africa. Among the donors, 19 (76%) died secondary to trauma. The average age for donors was 34 (interquartile range, 19-52) years old. In some donors, only one kidney was used because of a limited number of suitable recipients on the waiting list. Only two donors had been previously exposed to antiretroviral triple therapy...

Current theory holds that macrochimerism is essential to the development of transplant tolerance. Hematopoietic cell transplantation from the solid organ donor is necessary to achieve macrochimerism. Over the last 10 to 20 years, trials of tolerance induction with combined kidney and hematopoietic cell transplantation have moved from the preclinical to the clinical arena. The achievement of macrochimerism in the clinical setting is challenging, and potentially toxic due to the conditioning regimen necessary to hematopoietic cell transplantation and due to the risk of graft-versus-host disease...

BACKGROUND: The chronic kidney disease (CKD) is a worldwide critical problem, especially in developing countries. CKD patients usually begin their treatment in advanced stages, which requires dialysis and kidney transplantation, and consequently, affects mortality rates. This issue is faced by a mobile health (mHealth) application (app) that aims to assist the early diagnosis and self-monitoring of the disease progression. METHODS: A user-centered design (UCD) approach involving health professionals (nurse and nephrologists) and target users guided the development process of the app between 2012 and 2016...

Mycophenolic acid (MPA) is an approved immunosuppressive agent widely prescribed to prevent rejection after kidney transplantation. Wide between-subject variability (BSV) in MPA exposure exists which in part may be due to variability in enterohepatic recirculation (EHC). Several modeling strategies were developed to evaluate EHC as part of MPA pharmacokinetics, however mechanistic representation of EHC is limited. These models have not provided a satisfactory representation of the physiology of EHC in their modeling assumptions...

BACKGROUND: Acute kidney injury (AKI) is a common complication after liver transplantation and more frequently observed when high-risk grafts, such as DCD grafts are used. Our aim was to investigate the impact of the ischemia periods on development of AKI in DCD liver transplantation. METHODS: We performed a 2-center retrospective study with 368 DCD graft-recipients. Donor warm ischemia time (DWIT) was divided into agonal phase (withdrawal of life-support - cardiac arrest) and asystolic phase (cardiac arrest - start cold perfusion)...

Since 2012, the Organ Procurement and Transplantation Network (OPTN)/United Network for Organ Sharing (UNOS) has required transplant centers to record the citizenship and residency status of patients undergoing transplantation in the United States. This policy replaced the 5% threshold of the non-US citizen/non-U.S. residents (NC/NR) undergoing organ transplantation that could result in an audit of transplant center activity.We analyzed the frequency of NC/NR deceased donor organ transplants and wait list registrations at all US transplant centers using data provided by UNOS for that purpose to the UNOS Ad Hoc International Relations Committee...

Hepatitis C virus (HCV) infection affects many organs in the body, including the liver, kidneys, skin, joints and others. Although the hepatic manifestation of HCV has been widely studied, the extrahepatic manifestaions of HCV have not been fully appreciated. Studies have shown that patients with HCV have a higher risk of chronic kidney disease and end-stage renal disease, as well as poorer outcomes after kidney transplantation. Given these findings, it is important to screen HCV patients for presence of renal impairement in a timely manner...
