Filter by:The purpose of this study is to assess the safety and efficacy of RTA 402 in chronic kidney disease (CKD) patients with type 2 diabetes in a double-blind, placebo-controlled study when this compound is administered once daily for 16 weeks in an intrapatient dose escalation design.
Few educational intervention clinical trials have been conducted among those at risk for or with early chronic kidney disease. To the investigators' knowledge none have used digital storytelling as a means to deliver the educational message and have been conducted among American Indians, a group with high prevalence of chronic kidney disease and end stage kidney disease. The aims of the research project are to: 1. Quantify levels of chronic kidney disease knowledge and awareness among American Indians. 2. Determine the effectiveness of a culturally tailored health presentation with computerized digital stories made by American Indians for improving chronic kidney disease knowledge and factors thought to be preventative of chronic kidney disease or its progression at baseline and follow-up in a pilot educational clinical intervention trial.
This extension study of subjects previously enrolled in studies CTAP101-CL-3001 or CTAP101-CL-3002 allows long term evaluation of the safety and efficacy of CTAP101 Capsules in reducing elevated intact parathyroid hormone (iPTH) and correcting vitamin D insufficiency in stage 3 or 4 chronic kidney disease patients.
It is not known whether the combination of a heparin-grafted membrane plus citrate-containing dialysate is a valid alternative to regional citrate anticoagulation. This is a cross-over non-inferiority trial comparing these two anticoagulation strategies
The purpose of this study is to pilot test an mHealth technology-supported behavioral intervention designed to engage patients with diabetes and concurrent chronic kidney disease (CKD) in multiple behaviors which aim to reduce CKD progression. Participants will be randomized to the 6-month lifestyle intervention or to a wait-list control. The lifestyle intervention will be modeled after that used in the Diabetes Prevention Program (DPP) and the counseling intervention will be based on SCT, which will be paired with mobile technology-based dietary and physical activity monitoring. The wait-list control will receive 6 months of standard medical care followed by a delayed, but less intensive, 6-month intervention.
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.
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.
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.
