BACKGROUND: Polyomavirus-associated nephropathy (PVAN) following BK virus reactivation in kidney transplant recipients (KTR) can compromise graft survival. Lowering immunosuppression is the only established approach to prevent or treat PVAN but nonspecifically increasing host immune competence also augments rejection risk. Ex vivo T cell stimulation/expansion offers the possibility to generate BK-specific T cell lines for adoptive immunotherapy. The objective of this study was to develop and characterize a clinical scale protocol to generate BK-specific T cell lines from viremic KTR...

Left ventricular hypertrophy (LVH) is highly prevalent in kidney transplant recipients, and is associated with poor clinical outcome. Immunosuppressive agents might affect LVH behavior after kidney transplantation. This review is an appraisal of available data regarding LVH in renal transplantation and especially of studies that evaluated LVH response to treatment. In particular, the role of mammalian target of rapamycin inhibitors adopted as immunosuppressive agents in kidney transplantation is reviewed in the light of recent studies that have shown LVH regression induced by this class of medications in kidney transplant recipients with posttransplant cardiomyopathy...

A brain-dead donor experienced repeated cardiac arrests followed by severe hypotension requiring multiple vasoactive agents. These events were associated with severe lactic acidosis and dysregulated kidney function in the donor. A 10-hour treatment with extracorporeal membranous oxygenation was instituted, which was able to hemodynamically stabilize the donor. This treatment protocol resulted in the procurement of 2 viable kidney grafts transplanted into 2 recipients, who had immediate kidney graft function and excellent serum creatinine levels upon hospital discharge...

In renal transplant, multiple renal arteries in a donor require meticulous vascular reconstruction for successful allograft function in the recipient. Presence of more than 4 renal arteries is usually considered to be a relative contraindication for proceeding with renal donation. We report a living-donor renal transplant procedure where preoperative radiologic imaging of the donor showed 3 left renal arteries. Two additional arteries were identified intraoperatively. All 5 arteries were reconstructed during the back-table procedure, and the allograft was implanted in the recipient...

Acute gastroenteritis (AGE) is a common disease within the population. Most cases are self-limited. However, intensive treatment is sometimes necessary to ensure patient integrity. This disease is characterized by vomiting and/or diarrhea with blood or mucus, discomfort, fever, and nonspecific abdominal pain. Commonly involved pathogens in the developed world include: viruses, bacteria, and parasites. In this paper we report a rare cause of AGE.

INTRODUCTION: Tacrolimus is a calcineurin inhibitor used as an immunosuppressant drug in solid organ transplantation, and is mainly metabolized by cytochrome P450 (CYP) 3A4 and CYP3A5. Studies have shown an association between the CYP3A5 genotype and tacrolimus dose-adjusted trough concentrations. Variants in the genes PPARA, POR and CYP3A4 have recently been shown to influence tacrolimus metabolism. Furthermore, pharmacokinetic interaction between corticosteroid treatment and tacrolimus has been shown...

INTRODUCTION: Kidney transplantation (KT) is the preferred treatment for patients with end-stage renal disease (ESRD). To reduce the morbidity of the open surgery, a robotic-assisted approach has been recently introduced. Our aim is to evaluate surgical and functional results on 17 cases of robotic-assisted kidney transplantation (RAKT) performed at the same institution. MATERIALS AND METHODS: From July 2015 to June 2016, we performed 17 cases of RAKT from living donors in pre-emptive patients, who underwent laparoscopic nephrectomy...

BACKGROUND: Although residential segregation has been implicated in various negative health outcomes, its association with kidney transplantation has not been examined. METHODS: Age- and sex-standardized kidney transplantation rates were calculated from the Scientific Registry of Transplant Recipients, 2000-2013. Population characteristics including segregation indices were derived from the 2010 U.S. Census data and the U.S. Renal Data System. Separate multivariable Poisson regression models were constructed to identify factors independently associated with kidney transplantation among Blacks and Whites...

BACKGROUND: Grafts survive despite blood group antigens on the transplant being continuously exposed to antibodies in the blood of recipients in ABO-incompatible kidney transplantation (ABOi KT), owing to the mechanism of accommodation. We analyzed the immunodynamics of soluble ABH antigens in allografts from secretor donors and the influence of such immunodynamics on accommodation and subsequent graft survival in ABOi KT. METHODS: The genotype of a known human β-galactoside α-1,2-fucosyltransferase gene (FUT2), which determines soluble ABH antigen secretor status, was established in 32 donors for ABOi KT at the Severance Hospital, from June 2010 to July 2015...

Patients with chronic kidney disease (CKD), including those with end-stage renal disease, treated with dialysis, or renal transplant recipients have an increased risk for cardiovascular disease (CVD) morbidity and mortality. Dyslipidemia, often present in this patient population, is an important risk factor for CVD development. Specific quantitative and qualitative changes are seen at different stages of renal impairment and are associated with the degree of glomerular filtration rate declining. Patients with non-dialysis-dependent CKD have low high-density lipoproteins (HDL), normal or low total cholesterol (TC) and low-density lipoprotein (LDL) cholesterol, increased triglycerides as well as increased apolipoprotein B (apoB), lipoprotein(a) (Lp (a)), intermediate- and very-low-density lipoprotein (IDL, VLDL; "remnant particles"), and small dense LDL particles...

BACKGROUND: Operational tolerance is an alternative to lifelong immunosuppression after transplantation. One strategy to achieve tolerance is by T regulatory cells. Safety and feasibility of a T regulatory type 1 (Tr1)-cell-based therapy to prevent graft versus host disease in patients with hematological malignancies has been already proven. We are now planning to perform a Tr1-cell-based therapy after kidney transplantation. METHODS: Upon tailoring the lab-grade protocol to patients on dialysis, aims of the current work were to develop a clinical-grade compatible protocol to generate a donor-specific Tr1-cell-enriched medicinal product (named T10 cells) and to test the Tr1-cell sensitivity to standard immunosuppression in vivo to define the best timing of cell infusion...

BACKGROUND: The association of HLA mismatching with kidney allograft survival has been well established. We examined whether amino acid mismatches at the antigen recognition site of HLA molecules represent independent and incremental risk factors for kidney graft failure (GF) beyond those mismatches assessed at the antigenic (2-digit) specificity. METHODS: Data on 240,024 kidney transplants performed between 1987 and 2009 were obtained from the Scientific Registry of Transplant Recipients...

INTRODUCTION    Antibodies against donor`s human leukocyte antigens (HLA) play a significant role in the pathogenesis of antibody mediated rejection, although their role during the late post-transplant period is unknown. A non-HLA polymorphic antigenic system like major histocompatibility class I chain-related antigen A (MICA) might be another target for antibody responses involved in rejection. OBJECTIVES    We conducted a 7-year prospective study to determine the effect of positivity for anti-HLA and anti-MICA antibodies on kidney graft survival...

In April 2014, a kidney transplant recipient in the United States experienced headache, diplopia, and confusion, followed by neurologic decline and death. An investigation to evaluate the possibility of donor-derived infection determined that 3 patients had received 4 organs (kidney, liver, heart/kidney) from the same donor. The liver recipient experienced tremor and gait instability; the heart/kidney and contralateral kidney recipients were hospitalized with encephalitis. None experienced gastrointestinal symptoms...

BACKGROUND: We report clinical experience with combined heart and kidney transplantation (HKTx) over a 23-year time period. METHODS: From June 1992 to August 2015, we performed 83 combined HKTx procedures at our institution. We compared the more recent cohort of 53 HKTx recipients (group 2, March 2009 to August 2015) with the initial 30 previously reported HKTx recipients (group 1, June 1992 to February 2009). Pre-operative patient characteristics, peri-operative factors, and post-operative outcomes including survival were examined...

INTRODUCTION: Sarcopenia is characterized by an involuntary loss of skeletal muscle mass, strength, and function. Previous studies suggest that it is generally associated with aging and chronic kidney diseases. The focus of this study was on the association between sarcopenia and pre-sarcopenia in kidney transplant recipients. METHODS: Fifty-one patients who underwent kidney transplantation at Kansai Medical University Hospital were enrolled, and their sarcopenia status was evaluated between April and July 2016...

BACKGROUND: In kidney transplant recipients (KTRs) with hepatitis B virus (HBV) infection, immunosuppression may increase viral replication with increased risk for liver disease progression and HBV-related kidney diseases, factors that could adversely influence graft and patient outcomes. We aimed to analyze the impact of different phases of HBV infection on the outcomes in KTRs. METHODS: Using the Organ Procurement and Transplant Network/United Network for Organ Sharing database, we selected adult KTRs from 2001 to 2011 who received peri-operative antibody induction followed by calcineurin inhibitor/mycophenolate mofetil maintenance with/without steroid...

BACKGROUND: The current study aims to assess the association between acute kidney injury (AKI), renal function one year after transplantation and long-term adverse outcomes after cardiac transplantation. METHODS: A retrospective cohort study was performed including 471 adult cardiac transplantation recipients that survived the first postoperative year between 1984 and 2012. Primary outcome variables were long-term overall and renal survival. RESULTS: During the first postoperative week 40% (n=288) of the recipients developed AKI stage I, 22% (n=104) stage II, 13% (n=63) stage III and 4% (n=17) required temporary RRT...
