Robert D Toto
Diabetic nephropathy is the leading cause of kidney failure. Treatments with drugs that block the renin-angiotensin system have proven beneficial in slowing kidney disease progression among those with diabetes; their benefit is limited and they do not stop disease progression. Despite multiple clinical trials of various interventions including dual blockade of the renin-angiotensin system over the past 15 years, no new therapies have emerged to slow kidney disease progression in diabetes. SGLT-2 inhibitors are a new class of antiglycemic drugs that have been shown to lower blood glucose by inhibition of the sodium-glucose transporter 2 in the proximal tubule of the kidney...

BACKGROUND: Chronic kidney disease (CKD) is a leading cause of morbidity and mortality. Biomarkers that predict end-stage renal disease (ESRD) and/or mortality could usher in new therapeutics to halt this onslaught. While fibroblast growth factor (FGF)23 can predict both ESRD and mortality, it has not been studied in North American CKD patients of Asian ethnicity. METHOD: This is a prospective investigation about the role of FGF23 in 998 Canadian patients of Asian descent with CKD defined by an estimated glomerular filtration rate (eGFR) <60 mL/min/m2 and followed up for 3 years...

Discoidin domain receptors (DDRs) are a family of 2 non-integrin collagen receptors, DDR1 and DDR2, which display a tyrosine kinase activity. They are mainly expressed during embryonic development and their role during adulthood is very limited. DDR1 has been widely studied in several types of cancers, in atherosclerosis and fibrosis, but also in chronic kidney disease (CKD). This review focuses on the role of DDR1 in chronic nephropathies and on the effect of its deletion in the pathological processes involved in renal disease progression...

Belatacept (CTLA4Ig) is an emerging treatment in kidney transplantation. Lack of nephrotoxicity and possibly an inhibitory effect on the development of donor specific antibodies (DSA) make it an interesting agent in hand transplantation. In order to reduce CNI immunosuppression and preserve kidney function, we have added belatacept to the therapeutic regimen of 4 hand transplanted patients at month 4, at 6, 9, and 13 years after hand/forearm transplantation. Patients received 5mg/kg belatacept every 2 weeks, the dosing interval was extended to 4 weeks after 5 applications...

BACKGROUND: Leukocyte telomere length (LTL) is a potential biomarker of cancer prognosis; however, evidence for renal cell carcinoma (RCC) is inconsistent. METHODS: We investigated LTL and RCC-specific survival among 684 cases from the US kidney cancer study (USKC) and 241 cases from the prostate, lung, colorectal, and ovarian cancer screening trial (PLCO). Leukocyte telomere length was measured by quantitative polymerase chain reaction, and hazard ratios (HRs) and 95% confidence intervals (CIs) computed using multivariable Cox models...

BACKGROUND: Although the hemodynamic benefits of venovenous bypass (VVB) during liver transplantation (LT) are well appreciated, the impact of VVB on posttransplant renal function is uncertain. The aim of this study was to determine if VVB was associated with a lower incidence of posttransplant acute kidney injury (AKI). METHODS: Medical records of adult (≥18 years) patients who underwent primary LT between 2004 and 2014 at a tertiary hospital were reviewed. Patients who required pretransplant renal replacement therapy and intraoperative piggyback technique were excluded...

BACKGROUND: Compared with neurologic determination of death (NDD) donor organs, donation after cardiac death (DCD) donor organs have traditionally been considered of inferior quality owing to warm ischemia experienced during procurement. We present, to our knowledge, the first analysis of simultaneous pancreas and kidney (SPK) transplants using DCD donor organs in Canada. METHODS: We carried out a retrospective cohort study of SPK transplants from 13 DCD and 68 NDD donors performed between October 2008 and July 2016...

BACKGROUND: Renal fibrosis is a common pathway through which a variety of chronic kidney diseases progress to end-stage renal disease. Epithelial-mesenchymal transition (EMT) of renal proximal tubular cells is one of the most important factors in renal fibrosis. This study investigates if fasudil could influence EMT of renal proximal tubular cells. METHODS: HK-2 cells in passage 3-4 were used for all experiments. The cells were divided into five groups and treated with different concentrations of PTH and then observe cellular morphological changes at 0, 24 and 48 h using an inverted microscope and investigate the expression of the epithelial cell marker E-cadherin and the renal fibroblast marker α-smooth muscle actin (α-SMA)...

Both ethanol (EtoH) and atrazine (ATZ) have hepatic and nephro-toxic effects in rats. In the present study, the toxicity of EtoH (5 g kg(-1)) on the kidney and liver in the absence or in the presence of different doses of ATZ (50, 100, 300 mg kg(-1)) was evaluated after 21 days in rats. Results showed that the mixture effects on catalase and superoxide dismutase activities were more severe in both tissues compared to EtoH alone, especially as the dose of ATZ was increased. Hepatic malondialdehyde level (an index of lipid peroxidation) was increased from 20...

A series of organometallic Au(I) N-heterocyclic carbene (NHC) complexes was synthesized and characterized on anticancer activity in four human cancer cell lines. The compounds' toxicity in healthy tissue was determined using precision cut kidney slices (PCKS) as a tool to determine the potential selectivity of the Au complexes ex vivo. All evaluated compounds presented cytotoxic activity towards the cancer cells in the nano- or low micromolar range. The mixed Au(I) NHC complex - (ter-butylethynyl)-1,3-bis-(2,6-diisopropylphenyl)-imidazol-2-ylidene gold(I), bearing an alkynyl moiety as ancillary ligand, showed high cytotoxicity in cancer cells in vitro, while being barely toxic in healthy rat kidney tissues...

Guard cells dynamically adjust their shape to regulate photosynthetic gas exchange, respiration rates and defend against pathogen entry. Cell shape changes are determined by the interplay of cell wall material properties and turgor pressure. To investigate this relationship between turgor pressure, cell wall properties and cell shape, we focused on kidney-shaped stomata and developed a biomechanical model of a guard cell pair. Treating the cell wall as a composite of the pectin-rich cell wall matrix embedded with cellulose microfibrils, we show that strong, circumferentially-oriented fibres are critical for opening...

BACKGROUND: Parvovirus B19 is a small, non-enveloped, single-stranded DNA virus with a special affinity for the erythroid progenitor cells of the bone marrow. The first case of parvovirus B19 infection in a kidney transplant recipient (KTR) was reported in 1986. Data on the risk factors and specific clinical characteristics of parvovirus B19 infection remain insufficient. METHODS: We screened 602 KTRs for parvovirus B19 infection using parvovirus B19 polymerase chain reaction (PCR) from January 1990 to April 2016, and the clinical characteristics of patients with positive results were compared to those of age- and gender-matched patients with negative PCR results...

The purpose of this article is to perform the first pooled analysis on remote ischemic preconditioning (RIPC) used for the improvement of clinical outcomes of patients only undergoing on-pump coronary artery bypass grafting (CABG) in randomized controlled trials (RCTs). A systematic search was performed using PubMed, the Cochrane Library, and the Web of Science to identify studies that described the effect of RIPC on postoperative mortality in patients only undergoing on-pump CABG. The outcomes included postoperative mortality, postoperative morbidity (including incidence of myocardial infarction, atrial fibrillation, stroke, acute kidney injury, and renal replacement therapy), mechanical ventilation (MV), intensive care unit length of stay (ICU LOS), and hospital length of stay (HLOS)...
