BACKGROUND: Tenofovir disoproxil fumarate (TDF) is an anti-retroviral agent frequently used to treat human immunodeficiency virus (HIV). There are concerns regarding its potential to cause acute kidney injury, chronic kidney disease, and proximal tubulopathy. Although TDF can effectively suppress HIV after kidney transplantation, it is unknown whether use of TDF-based anti-retroviral therapy (ART) after kidney transplant (KT) adversely affects allograft survival. METHODS: We examined 104 HIV+ KT recipients at our center between 2001 and 2014...

REVIEW
Katayoun Behnam Sani, Birgit Sawitzki
Ever since its first application in clinical medicine, scientists have urged to induce tolerance towards foreign allogeneic transplants and thus avoid rejection by the recipient's immune system. This would circumvent chronic use of immunosuppressive drugs (IS) and thus avoid development of IS-induced side effects, which are contributing to the still unsatisfactory long-term graft and patient survival after solid organ transplantation. Although manifold strategies of tolerance induction have been described in preclinical models, only three therapeutic approaches have been successfully utilized in a still small number of patients...

Kidney transplantation (KTX) is a life-saving procedure for patients with end-stage renal disease. Expression levels of many genes in kidney vary between males and females which may play an essential role in the sex differences in graft function. However, whether these differences are affected after cross-sex-KTX is unknown. In the present study, we assessed post-operative changes in genotype, function and inflammatory responses of the grafts in same-sex and cross-sex-KTX. Single kidney transplants were performed between same and different sex C57BL/6 mice paired into 4 combination groups: female donor/female recipient (F/F); male donor/male recipient (M/M); female donor/male recipient (F/M); and male donor/female recipient (M/F)...

Background: Kidney transplantation is associated with harmful processes affecting the viability of the graft. One of these processes is associated with the phenomenon of ischaemia-reperfusion injury. Anaesthetic conditioning is a widely described strategy to attenuate ischaemia-reperfusion injury. We therefore conducted the Volatile Anaesthetic Protection of Renal Transplants-1 trial, a pilot project evaluating the influence of two anaesthetic regimens, propofol- vs sevoflurane-based anaesthesia, on biochemical and clinical outcomes in living donor kidney transplantation...

In 2013, OPTN/UNOS mandated that transplant centers collect data on living kidney donors (LKDs) at 6-months, 1-year, and 2-years post-donation, with policy-defined thresholds for the proportion of complete living donor follow-up (LDF) data submitted in a timely manner (60 days before or after the expected visit date). While mandated, it was unclear how centers across the country would perform in meeting thresholds, given potential donor and center-level challenges of LDF. To better understand the impact of this policy, we studied SRTR data for 31,615 LKDs between 1/2010-6/2015, comparing proportions of complete and timely LDF form submissions pre- and post-policy implementation...

Recently, a large randomized placebo-controlled trial indicated a beneficial effect of tolvaptan on the progression of autosomal dominant polycystic kidney disease (ADPKD) with near-normal kidney function. Meanwhile, the evidence of tolvaptan's efficacy in ADPKD with severe renal insufficiency was limited and higher frequency of liver enzyme elevations were observed in patients taking tolvaptan. Liver transplantation (LT) is the only curative treatment for patients with severe polycystic liver disease associated with ADPKD, but considering that liver injuries should be avoided particularly in patients who underwent LT, we must be careful to start tolvaptan in post-LT ADPKD patients...

Monoclonal gammopathy of undetermined significance (MGUS) is the common pre-malignant B cell disorders with a general prevalence of 3-5 % at age over 50. Because of the potential malignant transformation and immune insufficiency, pre-transplant MGUS recipient should be carefully followed after allograft transplantation. The post-transplant prognosis and quality of life (QOL) in patient with MGUS have not yet been fully determined. The aim of this study is to evaluate function and pathology of the renal allograft and self-assessment QOL changes during 2 years after transplantation in our case of MGUS-bearing recipient...

BACKGROUND: In the developed world, kidney transplantation (KT) in patients with human immunodeficiency virus (HIV) infection is well established. Developing countries concentrate 90% of the people living with HIV, but their experience is underreported. Regional differences may affect outcomes. OBJECTIVES: We compared the 3-year outcomes of patients with HIV infection receiving a KT in two different countries, in terms of incomes and development. METHODS: This was an observational, retrospective, double-center study, including all HIV-infected patients >18 years old undergoing KT...

PURPOSE: Acute cellular rejection is the major cause of immune-mediated graft failure early in the course of kidney transplantation, whereas chronic antibody-mediated rejection is a major contributor to graft loss in the late post-transplant phase. Based mainly on the results of short-term studies, the calcineurin inhibitor tacrolimus prevails over the mammalian target of rapamycin (mTOR) inhibitors. However, the toxicity profile of the two drug categories differs, making the interchange between them appealing...

BACKGROUND: Renal transplantation (RTx) is the treatment of choice for paediatric end-stage renal disease (ESRD). A major cause of morbidity and mortality after RTx is cardiovascular disease. Independent predictors of cardiovascular events were shown to constitute an endothelial dysfunction (ED). This study aims to evaluate Visfatin serum level in comparison to brachial artery flow-mediated dilatation (FMD) as a marker of endothelial dysfunction in paediatric RTx recipients. METHODS: Visfatin serum level has been evaluated in 30 patients on regular hemodialysis (HD), 36 patients post-RTx and 30 controls as a measure for ED, and has been compared to brachial artery FMD...

Kidney transplant in patients with liver cirrhosis and non-dialysis chronic kidney disease (CKD) is controversial. We report 14 liver cirrhotic patients who had persistently low MDRD-6 estimated-glomerular filtration rate (e-GFR) < 40 ml/min/1.73m2 for ≥ 3 months and underwent either liver transplant alone (LTA) (n=9) or simultaneous liver-kidney transplant (SLKT) (n=5). Pre-transplant, patients with LTA compared with SLKT had lower serum creatinine (2.5±0.73 vs. 4.6±0.52 mg/dl, P= 0.001), higher MDRD-6 e-GFR (21...

BACKGROUND: The risk of xenozoonosis mainly by porcine endogenous retrovirus (PERV) has been considered as one of the main hurdles in xenotransplantation and therefore should be elucidated prior to the clinical use of porcine corneal grafts. Accordingly, an investigation was performed to analyze the infectivity of PERVs from porcine keratocytes to human cells, and the long-term risk of transmission of PERVs was determined using pig-to-non-human primate (NHP) corneal transplantation models...

Atypical hemolytic uremic syndrome (aHUS) is a rare syndrome characterized by microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury that is usually caused by complement dysregulation. Complement factor H (CFH) is a regulator of the complement system produced in the liver, and CFH gene mutations are the most frequent causes of aHUS. To date, the therapeutic options for aHUS with CFH mutations have consisted of plasma infusions, plasma exchange, kidney transplantation, isolated liver transplantation, or combined liver and kidney transplantation...

Simultaneous pancreas and kidney transplantation (SPK) is currently the best therapeutic option for patients with type-1 diabetes and terminal renal failure. Renal transplantation restores fertility enabling women to pursue pregnancies. However, scarcity of available data on pregnancy outcomes in SPK impedes fair medical counseling. Medical files of all pregnancies that lasted ≥3 months among recipients of functional SPK performed between 1990 and 2015 in France were retrospectively analyzed. Twenty-six pregnancies in 22 SPK recipients were identified...

Bone health is assessed by bone mineral density (BMD). Other techniques such as trabecular bone score and microindentation could improve the risk of fracture's estimation. Our chronic kidney disease (CKD) patients presented worse bone health (density, microarchitecture, mechanical properties) than controls. More than BMD should be done to evaluate patients at risk of fracture. INTRODUCTION: BMD measured by dual-energy X-ray absorptiometry (DXA) is used to assess bone health in end-stage renal disease (ESRD) patients...
