Filter by:The purpose of this study is to evaluate the efficacy and safety of omarigliptin in participants with type 2 diabetes mellitus and moderate or severe chronic renal insufficiency or end stage renal disease on dialysis with inadequate glycemic control. The primary hypothesis of the study is that omarigliptin compared to placebo produces greater reduction in glycosylated hemoglobin (A1C) after 24 weeks.
The purpose of this study is to summarize the percentage of participants achieving age-specific Kidney Disease Outcomes Quality Initiative (KDOQI) targets for serum phosphorus in hyperphosphatemic children and adolescents with chronic kidney disease (CKD) who are on dialysis, following 8 weeks of treatment with lanthanum carbonate.
Background: Pseudoexfoliation (PEX) is characterised by the deposition of fibrillar material in an eye structures and many other parts of the body including kidneys and blood vessels. As both PEX and chronic kidney disease (CKD) are associated with oxidative stress and endothelial dysfunction we studied if the risk of PEX was increased in patients with CKD. Methods: Patients over age 40 with the diagnosis of CKD were included in the study. Chronic kidney disease was diagnosed as decreased glomerular filtration rate (GFR) of less than 60 mL/min/1.73 m². Study groups were arranged as group 1 consisting of HD receiving patients, group 2 consisting of stage 1-4 CKD patients and group 3 consisting of patients with normal kidney functions (control group). Demographic properties and the rate of PEX were evaluated and compaired between the groups.
The purpose of this study is to show biosimilarity of HX575 epoetin alfa with the US licensed reference product Epogen®/Procrit® when applied subcutaneously. This study is intended to generate data supporting that the efficacy and safety under treatment with HX575 and Epogen®/Procrit® are comparable.
Chronic kidney disease (CKD) is a major public health problem with a UK prevalence of 8-10%. The study hypothesis is to ascertain if intensive primary care led disease management programmes for CKD, supported by input from secondary care specialists will slow progression of CKD, improve blood pressure control and reduce cardiovascular events in patients on CKD registers. The investigators have partnered with Nene commissioning, a practice based commissioning group representing approximately 80 GP practices in Northamptonshire, to run this study. This will be a cluster randomised trial of an intensive, secondary care supported, CKD management programme in primary care vs normal CKD care. Randomisation will be at the level of the individual general practice. All general practices associated with Nene commissioning will be invited to participate. Randomisation of practices will be performed by the University of Leicester Clinical Trials Unit and the study will adhere to guidelines for undertaking randomised cluster trials. The aims of the study are: 1. To determine whether reinforcement of best practice in the management of key aspects of CKD care by clinical nurse specialists based in primary care, but with close links to colleagues from secondary care, improves clinical outcomes. 2. To foster excellence in CKD care 3. To improve coding of CKD and prevalence on chronic disease registers. 4. To increase interest in, and capacity for primary care research in Northamptonshire. 5. To implement and evaluate a new model of partnership working between primary and secondary care. The primary outcome measures will be changes in estimated glomerular filtration rate (eGFR). Secondary outcome measures will be blood pressure control, proteinuria, incidence of cardiovascular events,other biochemical parameters, referrals to secondary care and hospitalisations and mortality.
Recent research work has directed especial attention toward a distinct group of uremic retension molecules, called "protein-bound uremic toxins". The prototypes of this group of uremic toxins are indoxyl sulfate and p-cresol. These uremic toxins can promote production of free radical and impair antioxidant system and exerts direct toxicity on different cells and organs, including mesangial, tubular, endothelial cell and osteoblasts. Accumulation of these protein bound uremic toxins results in glomerular sclerosis and interstitial fibrosis of kidneys of uremic rats and confer skeletal resistance to parthyroid hormone in uremic patients. In hemodialysis, high serum p-cresol level is associated with higher cardiovascular mortality. AST-120 (Kremezin) is a carbonated oral absorbent extensively used in Japan and Korea. It has superior adsorption ability for certain small-molecular weight organic compounds known to accumulate in patients with CKD. In uremic rats and CKD patients, oral administration of AST-120 decreased the elevated pretreatment levels of serum indoxyl sulfate. In Japan, it was reported that AST-120 suppressed the increase in serum creatinine levels, prevented proteinuria, improved uremic symptoms, and, consequently, led to the postponement of dialysis therapy. Value of AST-120 on the outcome of late-stage CKD patients is still unknown. We hypothesized AST-120 through reduction of level of indoxyl sulfate and p-cresol can improved the morbidity- mortality of CKD patients. The principal aim of this prospective cohort study is to investigate the effectiveness of AST-120 in incidence of dialysis and mortality of late-stage CKD patients. Determination of this relationship can help to establish new therapeutic strategy in the treatment of late-stage CKD patients.
The primary aim of this study was to test the hypothesis that Paricalcitol, an active form of vitamin D, improved endothelial function in stage 3-4 chronic kidney disease (CKD) patients. A secondary aim of this trial was to study the relationship between endothelial function and plasma/serum and genetic biomarkers of bone mineral disorders in CKD (BMD-CKD) and renin angiotensin-aldosteron system (RAS) (angiotensin II and plasma renin activity).
Primary objective was to assess in subjects with CKD: Safety and tolerability of molidustat (BAY 85-3934), effects of molidustat on non-invasive hemodynamics Secondary objectives were to assess: Effects on pharmacodynamic parameters of erythropoiesis (erythropoietin, reticulocytes, erythrocytes, hemoglobin, hematocrit), pharmacokinetics of molidustat, exploratory biomarkers, ie, midregional pro-atrial natriuretic peptide, midregional pro-adrenomedullin, plasma renin activity, and optionally B-type natriuretic peptide, vascular endothelial growth factor, cyclic guanosine monophosphate, cyclic adenosine monophosphate, and noradrenaline
The purpose of this study is to compare the pharmacokinetic 25(OH)D and 1,25(OH)2D responses to a single oral dose of vitamin D2 or vitamin D3 in a group of Stage 5-Chronic Kidney Disease subjects requiring chronic hemodialysis.
There is currently little understanding of macrophage cholesterol homeostasis and foam cell formation across the spectrum of CKD. We hypothesize that an inverse relationship exist between the severity of CKD and processes underlying foam cell formation, and that the relationship becomes independent of serum lipoprotein levels as renal function declines. We propose to systematically examine scavenger receptors and cholesterol uptake as well as cholesterol transporters and efflux mechanisms in individuals with normal renal function, patients with moderate CKD and those with ESRD-HD. We further propose to determine if processed contributing to foam cell formation are related to the plasma lipid profile and if the relationship is modified by co-morbidities, such as diabetes, obesity, systemic inflammation which are common in this population and directly influence vascular integrity. These data will be critically important to understand when the abnormality starts and will provide crucial information.
