The diagnosis of acute rejection still relies on renal allograft biopsy. In fact, histological features including C4d staining can be useful to differentiate cellular and antibody-mediated acute rejection. However, the pathogenic mechanism to define the type of rejection is usually assessed by anti-HLA donor specific antibodies (DSA) monitoring. Suspicion of acute rejection is usually based on renal function deterioration. This method has low sensitivity. Moreover, creatinine increase follows graft injury and therefore the diagnosis is performed when there is an ongoing acute rejection...

We report a unique case of babesiosis presenting as sepsis after kidney transplantation. A 70-year-old female kidney transplant recipient presented with fever, hemolytic anemia, and acute kidney injury, and met three of four systemic inflammatory response syndrome (SIRS) criteria. Serology was positive for Babesia microti, confirmed by polymerase chain reaction. The patient was treated with atovaquone and azithromycin and made a full recovery. Reports of babesiosis after solid organ transplantation are rare, with only four prior cases reported in the literature...

Although post-transplant lymphoproliferative disorder (PTLD) is the second most common type of cancer in kidney transplantation (KT), plasma cell neoplasia (PCN) occurs only rarely after KT, and little is known about its characteristics and evolution. We included twenty-two cases of post-transplant PCN occurring between 1991 and 2013. These included 12 symptomatic multiple myeloma, eight indolent myeloma and two plasmacytomas. The median age at diagnosis was 56.5 years and the median onset after transplantation was 66...

BACKGROUND: Desensitization therapy may enable the patient to get allograft in sensitized recipient or solve the organ shortage in ABO-incompatible relationship in kidney transplantation (KT). However, the graft outcome and morbidity remains unclear. METHODS: We retrospectively analyzed 845 KT patients from January 2010 to February 2016 at Seoul National University Hospital. The patients were divided into three groups as follows: HLA-incompatible (HLAi) group, ABO-incompatible (ABOi) group, and control group...

Since the mineralocorticoid receptor (MR) was cloned 30 years ago, it has become clear that MR is expressed in extra-renal tissues, including the cardiovascular system, where it is expressed in all cells of the vasculature. Understanding the role of MR in the vasculature has been of particular interest as clinical trials show that MR antagonism improves cardiovascular outcomes out of proportion to changes in blood pressure. The last 30 years of research have demonstrated that MR is a functional hormone-activated transcription factor in vascular smooth muscle cells and endothelial cells...

BACKGROUND: Sepsis is a severe inflammatory response to infection. Excessive compensation to inflammation leads to dysregulated immune response that ultimately results in organ damage and lethality of sepsis. This study administered glutamine (GLN) in the early or late phase of sepsis to investigate its effects on regulating leukocyte programmed cell death 1 (PD-1) and its ligand (programmed cell death ligand 1 [PD-L1]) expression, macrophage function, inflammation, and acute kidney injury in sepsis...

Perioperative acute kidney injury is a common problem. While clinical trials seek to evaluate the impact of interventions on a variety of primary and secondary endpoints with the aim of implementing this knowledge to improve perioperative outcomes, the use of valid and relevant endpoints within clinical trials is of critical importance to achieving this goal. Suitable endpoints must be validated for the study population and in light of the clinical context under investigation while also considering regulatory requirements that govern the licensing of new therapeutic agents as well as the values of patients whose outcomes we seek to improve...

Diabetic nephropathy (DN) is one of the major causes of end-stage renal disease. Nod-like receptors nucleotide-binding domain and leucine-rich repeat pyrin-3 domain (NLRP3) inflammasome displays a considerable role in the chronic inflammatory state observed in diabetic patients. Urinary heat shock protein 72 (uHSP72) is a sensitive and specific biomarker for the early detection of acute kidney injury. The aim of this study was to evaluate NLRP3 relative gene expression, its correlation with inflammatory and oxidative stress markers, and to assess the value of uHSP72 in the early detection of DN in type 2 diabetic patients with different degrees of DN...

The paper describes a case of diagnosing acute renal graft rejection concurrent with polyomavirus nephropathy. Histochemical and electron microscopic methods were used to examine biopsy specimens, which showed morphological changes occurring in the allograft, the ultrastructural characteristics of polyomavirus and the features of its spread in kidney tissue structures.

Detecting acute rejection in kidney transplantation has been traditionally done using histological analysis of invasive allograft biopsies, but this method carries a risk and is not perfect. Transplant professionals have been working to develop more accurate or less invasive biomarkers that can predict acute rejection or subsequent worse allograft survival. These biomarkers can use tissue, blood or urine as a source. They can comprise individual molecules or panels, singly or in combination, across different components or pathways of the immune system...

A 75-year-old man was admitted with abdominal pain and fresh rectal bleeding. Significantly, he had no risk factors for Clostridium difficile infection. An abdominal CT demonstrated colonic thickening, and flexible sigmoidoscopy identified pseudomembranous colitis-like lesions. After initial treatment as C. difficile colitis, a stool sample revealed Escherichia coli O157:H7 infection. Antibiotic therapy was stopped due to the risk of lysis-mediated toxin release, but unfortunately, the patient continued to deteriorate...

Ultramarathon races are fairly demanding and impose substantial physiological stress on healthy athletes. These competitions may thus be considerably more challenging for individuals with diabetes. This case study aims to describe glycemic control, muscle damage, inflammation, and renal function in 3 athletes with type 1 diabetes during a successful performance in a relay ultramarathon. The team completed the race in 29 hours and 28 minutes, earning third place. The total distance covered by each athlete was 68...

Dialysis initiation rates among older adults, aged 75 years or greater, are increasing at a faster rate than for younger age groups. Older adults with advanced CKD (eGFR < 30 ml/min/1.73 m(2)) typically lose renal function slowly, often suffer from significant comorbidity and thus may die from associated comorbidities before they require dialysis.A patient's pattern of renal function loss over time in relation to their underlying comorbidities can serve as a guide to the probability of a future dialysis requirement...

Renal replacement therapy (RRT) is a key component in the management of severe acute kidney injury (AKI) in critically ill patients. Many cohort studies, meta-analyses, and two recent large randomized prospective trials which evaluated the relationship between the timing of RRT initiation and patient outcome remain inconclusive due to substantial differences in study design, patient population, AKI definition, and RRT indication. A cause-specific diagnosis of AKI based on current staging criteria plus a sensitive biomarker (panel) that allows creating a homogeneous study population is definitely needed to assess the impact of early versus late initiation of RRT on patient outcome...

Triggered by the successful administration of the proteasome inhibitor bortezomib in kidney transplant recipients with acute or chronic antibody-mediated rejection, we evaluated the effect of the proteasome inhibitor CEP-18770 and of the selective immunoproteasome inhibitor ONX-0914 on cellular and humoral alloimmunity. Cellular alloimmunity was assessed by cell proliferation in a two-way mixed lymphocyte reaction (MLR) with human peripheral blood mononuclear cells (PBMC). For assessing humoral alloimmunity we developed a method, where humoral alloimmunity was induced in one-way MLR...

Leiomyosarcoma (LMS) is a rare but well-recognized malignant soft tissue sarcoma of smooth muscle origin. Metastases commonly occur in the lungs, liver, kidney, brain, and bone. Cases of metastatic osseous lesions or other extradural space-occupying masses secondary to LMS leading to neurologic compromise are relatively commonplace in the literature. Conversely, cases of intramedullary spinal cord metastasis (ISCM), an unusual entity as a sequela of any cancer, are exceedingly rare as a consequence of LMS. Only 2 cases of an ISCM from LMS are currently documented in the literature, and to the best of our knowledge, no case is described in the rehabilitation literature...

Little is known about concurrent infection with hepatitis C virus (HCV) and Streptococcus pneumoniae, which causes invasive pneumococcal disease (IPD). We hypothesized that co-infection with HCV and S. pneumoniae would increase risk for death and complications. We captured sociodemographic and serologic data for adults with IPD in a population-based cohort study in northern Alberta, Canada, during 2000-2014. IPD patients infected with HCV were compared with IPD patients not infected with HCV for risk of in-hospital deaths and complications by using multivariable logistic regression...

Renal ischemia/reperfusion (I/R) injury is a debilitating condition that leads to loss renal function and damage to kidney tissue in the majority of patients with acute kidney disease. Previous studies have indicated that autophagy serves a protective function in renal I/R injury. In the present study, the effect of the anthelmintic niclosamide in the regulation of inflammatory responses in kidney I/R was investigated. A total of 40 Sprague-Dawley rats were randomly divided into the following 5 groups (n=8 in each group): Sham group; renal I/R injury; renal I/R injury plus 3‑methyladenine (3‑MA) treatment (15 mg/kg); renal I/R injury plus niclosamide (25 mg/kg); and renal I/R injury plus rapamycin (10 mg/kg)...
