Filter by:Current treatments for ARAS based on restoring blood flow alone have been unsuccessful at recovering kidney function. For this reason we are studying a stem cell product called "mesenchymal stem cells" or MSC. Mesenchymal stem cells (MSC) are grown from a person's own fat tissue (obtained as a fat biopsy) and infused back into the patient's own kidney. This study is also being done to determine if the MSC infusion prior to percutaneous transluminal renal angioplasty with stenting (PTRA) further enhances changes in single kidney blood flow and restoration of kidney function, as well as to assess the relationship between MSC dose and measures of kidney function.
This national study was a post-marketing surveillance study conducted in Korea from 29 August 2008 to 28 August 2012 to meet local regulatory requirements for Mircera (monopegylated-epoetin beta). Prospective patient-based data collection was evaluated for safety/risk assessments and effectiveness. No specific study-related procedures are required. Patients were to be followed up as long as possible at the physician's discretion.
The COMBINE clinical trial is a pilot study evaluating the effects of nicotinamide and lanthanum carbonate on serum phosphate and fibroblast growth factor 23 (FGF23) in patients with Chronic Kidney Disease (CKD) stages 3-4.
The purpose of this study is to compare two different dosing methods of epoetin alfa and their effectiveness in maintaining hemoglobin levels between 10.0 to 11.0 g/dL in in patients with chronic kidney disease (CKD) receiving hemodialysis.
Chronic kidney disease (CKD) is a major global health problem associated with substantial costs and resource utilization. Currently, CKD affects more than 500 million people worldwide. Patients with CKD have unacceptably high mortality rates due to cardiovascular (CV) causes, which are not entirely explained by traditional CV risk factors. The mortality rates in advanced CKD are six times higher compared to the Medicare population, with CVD accounting for the overwhelming majority of deaths. Insulin resistance (IR) is common in CKD patients and may represent a central link between CKD and the increased CVD risk observed in this population. Insulin resistance may increase CV risk by impairing and worsening endothelial function, increasing reactive oxygen species, and exacerbating systemic inflammation-hence, insulin resistance is considered a "non-traditional CV risk factor" in CKD. Obesity (defined by a body mass index [BMI] of at least 30 kg/m2) is a major public health problem-the upward trend in obesity prevalence across regions and continents is a worldwide concern. Obesity increases the risk for cardiovascular disease and death. In the general population, obesity hastens death by 9.4 years. Obesity is an independent risk factor for CKD. Besides its contribution to the development of diabetes and hypertension, increased fat mass may also have a direct impact on kidney function. In spite of the increasing prevalence of both obesity and CKD, the impact of obesity in the CKD population is not known, especially in terms of the exaggerated metabolic disturbances associated with their coexistence. It is highly likely that these two conditions have profound interactions that exaggerate the severity of the metabolic derangements when they coexist, particularly in regards to adipokine dysregulation, the risk of "insulin resistance", and downstream effects on vascular health. The current proposal will attempt to characterize the relative and combined impact of both obesity and CKD on metabolic disturbances, which may aid in risk stratification and identifying specific targets for intervention. The ultimate goal of this proposal is to understand the relative and combined impact of obesity and CKD on the generation and maintenance of insulin resistance and their impact on cardiovascular health. Specific Aim 2: To study the effects of metformin, an AMPK activator, on metabolic disturbances associated with obesity and moderate CKD. S.A.2.a: To test if metformin will improve LAR in obese patients with moderate CKD compared to placebo. S.A.2.b: To test if metformin will improve markers of systemic inflammation, oxidative stress, endothelial dysfunction in obese patients with moderate CKD compared to placebo. S.A.2.c: To test if metformin will improve atherosclerosis markers and reduce clinical CVD events in obese patients with moderate CKD compared to placebo. Hypothesis: The investigators hypothesize that the administration of metformin in obese CKD patients will significantly improve the adipokine profiles-particularly through a reduction in LAR. Additionally, that it will improve systemic inflammation, oxidative stress and endothelial function, which may or may not be mediated by changes in adipokines. Finally, the investigators hypothesize that improvements in these markers of vascular health will translate into reduced arterial stiffness and less clinical CV events
Among adult individuals with type 2 diabetes mellitus and at risk for heart failure with impaired relaxation of the heart mildly reduced kidney filtration function (Type 4 cardiorenal syndrome) this trial will evaluate the quantitative impact of 38 weeks of treatment with exenatide extended-release injections versus placebo. on a cardiac biomarker blood test score, cardiac fibrosis seen on magnetic resonance scanning, cardiac strain identified by ultrasonography and strain rate imaging, and a kidney urine biomarker score.
Vitamin D is not seen anymore only as a phosphocalcic and bone hormone, but also as having an effect on global health (anti-infective, anti-inflammatory, anti-tumour roles and cardiovascular protection). Until recently, vitamin D repletion was defined as the minimal concentration that enables the prevention of rickets in children and osteomalacia in adults, i.e, approximately 8 ng/mL (20 nmol/L). However, most of the international experts agree to set minimal threshold of 25 OH vitamin D serum concentration, higher than the one previously admitted, with a limit of 20 ng/mL (50 nmol/L) to define a vitamin D deficiency and a limit of 30 ng/mL (75 nmol/L) to define vitamin D insufficiency. Recommendations for Vit D supplementation in healthy children were updated in France in 2012. The invariable supplementation of infants and toddlers is efficient since deficiency-related rickets have almost disappeared; however there is very few information in ill children populations. Vit D supplementation tolerance is usually considered as good and over-dosage risks are low, however these studies were conducted more than 30 years ago, and as far as we know, there is no study about calcium urinary excretion kinetics after intake of a 100 000 IU vial of cholecalciferol (Uvedose®). When 25 OH vitamin D serum concentrations exceeds 200 ng/mL, which is very rare in daily practice, toxic effects of Vit D may theoretically be observed, particularly hypercalcemia and hypercalciuria. Vitamin D deficit is very common in children with chronic kidney disease (CKD) with a 50 to 92% prevalence depending on the studies; it it is a risk factor for secondary hyperparathyroidism. Although international guidelines regarding the care of CKD children recommend 25 OH vitamin D serum concentrations over 75 nmol/L, there are no practical recommendations in terms of dose and frequency of native Vit D treatment. Therefore, the objectives of the present study has are the following: - to validate prospectively the efficacy of our service usual care for Vit D supplementation of children and adolescents seen in the paediatric nephrology department. - and to study the effect of Vit D supplementation (100 000 IU vial of cholecalciferol) on calciuria in these patients.
This observational, multi-center, open-label, prospective study will evaluate the relationship between serum interleukin-6 (IL-6) and C-reactive protein (CRP) levels and methoxy polyethylene glycol-epoetin beta dosage in participants with chronic kidney disease (CKD) on dialysis. Participants will be recruited who are on stable methoxy polyethylene glycol-epoetin beta maintenance therapy or will initiate therapy with methoxy polyethylene glycol-epoetin beta.
This study is a prospective, non-interventional, cross-sectional multicenter survey. The aim is to better understand the current therapy pattern for anemia in chronic kidney disease (CKD) treated with erythropoiesis-stimulating agents (ESAs) and not on-dialysis patient population in Israel. Participating physicians will be requested to complete a satisfaction survey for anemia treatment for eligible patients with CKD not on dialysis. The survey will be completed twice, once at study start and once at six months' follow-up.
Patients with end-stage renal disease (ESRD) have a high prevalence of impaired glucose metabolism. The pathophysiological cause is uncertain, but disturbances in the secretion, elimination and effect of glucagon, insulin and the two incretin hormones glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), probably play important roles. Our research group has previously found that dialysis patients without type 2 diabetes mellitus (T2DM) have a reduced incretin effect and an inability to suppress glucagon after a meal - two early pathophysiological characteristics of patients with T2DM and normal kidney function. The aim of the project is to provide a detailed description of the mechanisms underlying the (patho)physiological effects of the incretin hormones in patients with ESRD. We plan to investigate the above mentioned disturbances during fasting and hyperglycaemic conditions using incretin infusions during glucose clamping. Furthermore, stable isotopic tracers will be used to determine the effect of the incretin hormones on the endogenous glucose handling. We hypothesise that the effects of the incretin hormones in ESRD will be reduced in respect to healthy control subjects.
