Renal cell carcinoma (RCC) ranks the first death rate among the urogenital tumors, whereas its incidence follows the incidences of prostate and bladder cancer. The diagnosis of RCC at early stages allows immediately undertaking appropriate treatment, which significantly increases patients' survival rate. Early and accurate diagnosis avoids inadequate treatment, provides the disease progression forecast, and permits to apply more efficient therapy. Unfortunately, the small renal tumors are usually asymptomatic resulting in the late diagnosis and, therefore, low efficacy of treatment...

: Hemolytic uremic syndrome (HUS) is a disease characterized by thrombotic microangiopathy with a triad of non-immune hemolytic anemia, thrombocytopenia, and renal impairment. Approximately 10% of cases of HUS are classified as atypical (aHUS). While today many genetically forms of aHUS pathology are known, only about 50% of carriers precipitate the disease. The reason remains unclear, and triggering events like intercurrent infections have been postulated. In rare cases, influenza A is the known trigger of aHUS; however, no cases of influenza B have been reported...

PURPOSE: Care bundles are recommended in patients at high risk for acute kidney injury (AKI), although they have not been proven to improve outcomes. We sought to establish the efficacy of an implementation of the Kidney Disease Improving Global Outcomes (KDIGO) guidelines to prevent cardiac surgery-associated AKI in high risk patients defined by renal biomarkers. METHODS: In this single-center trial, we examined the effect of a "KDIGO bundle" consisting of optimization of volume status and hemodynamics, avoidance of nephrotoxic drugs, and preventing hyperglycemia in high risk patients defined as urinary [TIMP-2]·[IGFBP7] > 0...

INTRODUCTION: The outcomes of patients who fail their kidney transplant and return to dialysis (RTD) has not been investigated in a nationally representative sample. We hypothesized that variations in management of transplant chronic kidney disease stage 5 leading to kidney allograft failure (KAF) and RTD, such as access, nutrition, timing of dialysis, and anemia management predict long-term survival. METHODS: We used an incident cohort of patients from the United States Renal Data System who initiated hemodialysis between January 1, 2003 and December 31, 2008, after KAF...

This study was aimed to evaluate the effects on some inflammatory markers of two dialytic treatments [bicarbonate dialysis (BHD) and hemodiafiltration (HDF)] in patients with severe chronic kidney disease. We evaluated: blood glucose, homeostasis model assessment insulin resistance index, homocistein (Hcs), high sensitivity C-reactive protein (hs-CRP), fibrinogen, lipoprotein (a) [Lp(a)], metalloproteinases-2, and -9 (MMP-2 and MMP-9), and soluble receptor for advanced glycation end products (sRAGE). Considering the all sample, we observed a decrease of sRAGE with BHD, but not with HDF...

Adenosine is a nucleoside that is particularly interesting to many scientific and clinical communities as it has important physiological and pathophysiological roles in the kidney. The distribution of adenosine receptors has only recently been elucidated; therefore it is likely that more biological roles of this nucleoside will be unveiled in the near future. Since the discovery of the involvement of adenosine in renal vasoconstriction and regulation of local renin production, further evidence has shown that adenosine signaling is also involved in the tubuloglomerular feedback mechanism, sodium reabsorption and the adaptive response to acute insults, such as ischemia...

OBJECTIVE: Hypersensitivity to vitamin D (HVD) due to a loss of function mutation of the CYP24A1 gene, which encodes vitamin D catabolizing enzyme was initially described as a cause of acute hypercalcemia in children and chronic renal diseases in adults. METHODS: We describe the first case of a patient presenting a calcium pyrophosphate deposition disease (CPDD) revealing a HVD. RESULTS: An abnormality of phospho-calcic metabolism was discovered during the course of an etiological workup for CPDD in a 52-year-old patient...

A tumor composed of large eosinophilic cells in the liver raises concern for hepatocellular carcinoma, which is typically composed of such cells. However, there are other tumors, both primary and metastatic, that may be composed predominantly of large epithelioid cells. Distinction of these tumors from hepatocellular carcinoma and from each other is of obvious importance for patient management. Similarly, a clear cell tumor anywhere in the body triggers suspicion for renal cell carcinoma. However, other tumors, including hepatocellular carcinoma can rarely be composed entirely of cell cells and the distinction of these from one another, and of primary from metastatic disease is vital...

BACKGROUND: The potential survival benefit of bilateral internal thoracic artery (BITA) grafting in patients undergoing off-pump coronary artery bypass graft surgery (OPCABG) is controversial owing to the technical complexity of these operations. Our objective was to compare the outcome of patients undergoing OPCABG with BITA to the outcome of patients undergoing OPCABG with a single internal thoracic artery (SITA) and saphenous vein grafts or radial artery. METHODS: Five hundred and thirty-five consecutive patients who underwent OPCABG BITA at our institute between 2000 and 2008 were compared with 422 patients who underwent OPCABG with SITA...

Heart failure (HF) is the most common discharge diagnosis across the United States, and these patients are particularly vulnerable to readmissions, increasing attention to potential ways to address the problem. The study cohort was derived from the Healthcare Cost and Utilization Project's National Readmission Data 2013, sponsored by the Agency for Healthcare Research and Quality. HF was identified using appropriate International Classification of Diseases, Ninth Revision, Clinical Modification codes. Readmission was defined as a subsequent hospital admission within 30 days after discharge day of index admission...

In an attempt to identify a feline model of acute or chronic kidney disease, this study was designed to evaluate the effects of 15 or 30 min of bilateral renal ischemia (RI) and 60 min of unilateral RI with delayed contralateral nephrectomy as models of acute kidney injury and chronic interstitial fibrosis in cats. Adult, purpose-bred, USDA Class A cats (n = 14) were randomly assigned to receive bilateral RI for 15 min (n = 3) or 30 min (n = 3), unilateral RI for 60 min with a delayed (2 wk) contralateral nephrectomy (n = 5), or sham unilateral RI with a delayed contralateral nephrectomy (n = 3)...

AIMS: Renal dysfunction is a risk factor for cardiovascular disease, including atrial fibrillation (AF) and mortality. However, the exact pathobiology linking different renal dysfunction measures, such as albumin excretion or glomerular filtration rate (GFR), to cardiovascular- and AF risk are unclear. In this study, we investigated the association of several renal function measures and incident AF, and whether the relation between renal measures and outcomes is modified by AF. METHODS AND RESULTS: We examined 8265 individuals (age 49 ± 13 years, 50% women) included in the PREVEND study...

Hyperfiltration is a well-known risk factor in progressive loss of renal function in chronic kidney disease (CKD) secondary to various diseases. A reduced number of functional nephrons due to congenital or acquired cause(s) results in hyperfiltration in the remnant kidney. Hyperfiltration-associated increase in biomechanical forces namely pressure-induced tensile stress and fluid flow-induced shear stress (FFSS) determine cellular injury and response. We believe the current treatment of CKD yields limited success because it largely attenuates pressure-induced tensile stress changes but not the effect of FFSS on podocytes...

BACKGROUND: Sleep disorders are very common in patients with chronic kidney disease and they may not always subside after kidney transplantation. AIM AND METHODS: The aim of this cross-sectional study was to evaluate the self-reported quality of sleep, insomnia problems in particular, and examine the factors that disturb sleep of kidney transplant recipients (KTx: n=152) in comparison to age- and sex-matched patients on dialysis (HD: n=67) and participants with normal renal function (NOR: n=49), through the administration of the Athens Insomnia Scale (AIS) at least six months after transplantation...

The transcription factor NF-kB plays a pivotal role in the pathogenesis of rheumatoid arthritis. Here we attempt to slow arthritis progression by co-delivering the glucocorticoid dexamethasone (Dex) and small-interfering RNA targeting NF-kB p65 using our previously developed polymeric hybrid micelle system. These micelles contain two similar amphiphilic copolymers: polycaprolactone-polyethylenimine (PCL-PEI) and polycaprolactone-polyethyleneglycol (PCL-PEG). The hybrid micelles loaded with Dex and siRNA effectively inhibited NF-kB signaling in murine macrophages more efficiently than micelles containing either Dex or siRNA on their own...

Over the past few years, treatment options for chronic hepatitis C virus (HCV) infection have evolved dramatically. The current approved interferon-free direct-acting antiviral (DAA) regimens have been shown to be safe and effective with sustained virologic response (SVR) rates of >90% in most patients. Unique issues yet remain such as the challenges in patients with impaired renal function or decompensated cirrhosis. Patients with stage 4-5 chronic kidney disease (CKD) have a higher prevalence of HCV infection compared with the general population...
