Objective: To analyze the risk factors and prognosis of bleeding in very old male patients with stage 5 chronic kidney disease (CKD). Methods: The clinical data of 143 very old male patients with stage 5 CKD was retrospectively analyzed. According to the occurrence of bleeding, the patients were divided into two groups including the hemorrhage group and the non-hemorrhage group. The history of diseases, renal function, blood cell parameters and coagulation index were compared and analyzed between the two groups...

Renal cell carcinoma (RCC) is the most common subtype of kidney cancer. Currently, there is a lack of efficient treatment for RCC. Bicyclol, an anti-hepatitis drug, has been demonstrated to possess anti-tumor properties. However, the effect of bicyclol in RCC remains elusive. Therefore, the aim of this study is to investigate the biological effects of bicyclol on RCC and the underlying mechanisms. The data from this study indicated that bicyclol markedly induced cell apoptosis and cell cycle arrest and increased the production of reactive oxygen species (ROS) in RCC cells...

Immunosuppression in kidney transplantation is still largely driven by center-specific protocols and adjusted according to the presence of graft dysfunction, drug toxicity or infection. Due to the current inability to titrate immunosuppression to the needs of every single patient, this approach is burdened by an increased risk of under or over-immunosuppression. To extend allograft survival, immunosuppression should be decided based on reliable biomarkers capable of quantifying the alloimmune response and/or noninvasively diagnosing acute rejection...

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease, accounting for 10% of European patients on renal replacement therapy. In the previous years, many approaches to slow the progression of ADPKD were studied and many clinical trials published. In addition to having diagnostic role, the description of the genotype is even important to predict the progression of the disease and contributes, combined with several other factors, to a more precise patients classification...

Patients affected by chronic kidney disease (CKD) exhibit a high risk of cardiovascular mortality that is poorly explained by traditional risk factors. There is a growing awareness about the role of derangement of mineral metabolism that is currently accepted as a trigger and sustainer of cardiovascular disease (CVD) in CKD patients. The synthetic definition of CKD mineral and bone disorder (CKD-MBD) split the concept that the indexes of mineral metabolism extend their effects beyond the bone until the vascular wall and metabolic milieu of CKD patients through complex pathways...

A direct and independent association between serum phosphate (P) levels and mortality has been reported. High circulating P concentrations, still within the normal range, was associated with unfavourable outcomes in normal subjects as well as in chronic kidney disease (CKD) patients. Experimental data support the notion that P overload may hamper survival expectancy, directly inducing vascular, skeletal, and renal ageing. The balance of P results from dietary intake, intestinal absorption, glomerular filtration, tubular resorption, and hormonal asset...

Coupled plasma filtration and adsorption (CPFA) is a detoxification system that combines a plasma adsorption circuit and a continuous renal replacement therapy circuit. Its main application is for sepsis and septic shock with or without acute renal failure. Several recent studies have suggested that CPFA can reduce the mortality when the volume of plasma absorbed on the styrenic resin is at least >0.18 L/kg/day. At present, new applications for CPFA are under investigation, also in patients without significant kidney failure...

The kidney contains the functional units, the nephrons, surrounded by the renal interstitium. Previously we discovered that, once Six2-expressing nephron progenitor cells and Foxd1-expressing renal interstitial progenitor cells form at the onset of kidney development, descendant cells from these populations contribute exclusively to the main body of nephrons and renal interstitial tissues, respectively, indicating a lineage boundary between the nephron and renal interstitial compartments. Currently it is unclear how lineages are regulated during kidney organogenesis...

After briefly discussing endothelial glycocalyx and its role in vascular physiology and renal disease, this overview focuses on its degradation very early in the course of microbial sepsis. We describe our recently proposed mechanism for glycocalyx degradation induced by exocytosis of lysosome-related organelles and release of their cargo. Notably, an intermediate in nitric oxide synthesis, NG-hydroxy-l-arginine, shows efficacy in curtailing exocytosis of these organelles and improvement in animal survival...

Damage of human renal glomerular endothelial cells (HRGECs) of the kidney represents the linchpin in the pathogenesis of the hemolytic uremic syndrome (HUS) caused by Shiga toxins (Stxs) of enterohemorrhagic Escherichia coli (EHEC). We performed a comprehensive structural analysis of the Stx receptor glycosphingolipids (GSLs) globotriaosylceramide (Gb3Cer, Galα4alβ4Glcβ1Cer) and globotetraosylceramide (Gb4Cer, GalNAcβ3Galα4Galβ4Glcβ1Cer) and their distribution in lipid raft analogue detergent-resistant membranes (DRMs) and nonDRMs prepared from primary HRGECs...

Glycemic excursions, independent of average glucose, have been implicated in the development of diabetic implications. It is unknown if low 1,5-anyhydroglucitol (1,5-AG) are associated with advanced stages of kidney disease independent of kidney function and glycemia. In the Atherosclerosis Risk in Communities Study (N = 13,277), we used structural equation modeling to estimate the association between serum 1,5-AG levels and end-stage renal disease from baseline (1990-1992) through 2013 with adjustment for demographics, risk factors, a latent variable for glycemia (diabetes status, fasting glucose, hemoglobin A1c, fructosamine, glycated albumin), and a latent variable for kidney function (creatinine, cystatin C, β2-microglobulin)...

AIM: Acute kidney injury (AKI) is common following deliberate self-poisoning with a combination washing powder containing oxalic acid (H2C2O4) and potassium permanganate (KMnO4). Early and rapid increases in serum creatinine (sCr) follow severe poisoning. We investigated the relationship of these increases with direct nephrotoxicity in an ongoing multicenter prospective cohort study in Sri Lanka exploring AKI following poisoning. METHODS: Multiple measures of change in kidney function were evaluated in 48 consenting patients who had serial sCr and serum cystatin C (sCysC) data available...

A large number of previous clinical studies have reported a delayed graft function for brain dead donors, when compared with living relatives or cadaveric organ transplantations. However, there is no accurate method for the quality evaluation of kidneys from brain‑dead donors. In the present study, two‑dimensional gel electrophoresis and MALDI‑TOF MS‑based comparative proteomic analysis were conducted to profile the differentially‑expressed proteins between brain death and the control group renal tissues...

Renal cell carcinoma (RCC) is the most common neoplasm of the adult kidney, and clear cell RCC (ccRCC) represents its most common histological subtype. Although several studies have reported high expression of miR-122 in ccRCC, its physiological role remains unclear. To clarify the role of miR-122 in ccRCC, we compared miR-122 expression levels in non-cancerous tissue and ccRCC. Significant upregulation of miR-122 was observed in ccRCC specimens. Moreover, ccRCC patients with high miR-122 expression showed poor progression-free survival compared to those with low miR-122 expression...

Technical advances in the development of organoid systems enable cell lines, primary adult cells, or stem or progenitor cells to develop into diverse, multicellular entities, which can self-renew, self-organize, and differentiate. These 3D organoid cultures have proven to be of value in increasing our understanding of the biology of disease and offer the potential of regenerative and genetic therapies. The successful application of 3D organoids derived from adult tissue into urological cancer research can further our understanding of these diseases and could also provide preclinical cancer models to realize the precision medicine paradigm by therapeutic screening of individual patient samples ex vivo...

MicroRNAs (miRNAs) have been reported to regulate essential biological processes, and their expression was shown to be affected by pathological processes and drug-induced toxicity. Amphotericin B (AmB) can cause liver and kidney injury, but a recently developed complex of AmB with copper (II) ions (AmB-Cu(2+)) exhibits a lower toxicity to human renal cells while retaining a high antifungal activity. The aim of our study was to assess AmB-Cu(2+)- induced changes in the miRNA profile of renal cells and to examine which biological processes are significantly affected by AmB-Cu(2+)...

BACKGROUND: The presence and severity of proteinuria is considered an important prognostic marker in patients with chronic kidney disease (CKD) and is associated with mortality and morbidity. Cathepsin L is highly expressed in the foot processes of podocytes in the kidney, which serves as an ultrafiltration barrier. Cathepsin L is also up-regulated in the setting of inflammation as a feature of CKD. Therefore, we postulated that proteinuria severity in CKD patients might correlate with increased serum levels of cathepsin L...
