Filter by:Studies have shown that patients with chronic kidney disease in hemodialysis have a low vitamin K status which is believed to be related to an increased risk of atherosclerosis and increased bleeding tendency. The underlying causes of low vitamin K status in hemodialysis patients is unknown. Thus, the aim of this study is to investigate why hemodialysis patients have a low vitamin K status and how to improve it. This study is composed of five trials. Four of them are based on possible hypotheses to the low vitamin K status. The hypotheses are: 1. The daily intake of vitamin K is insufficient. 2. Vitamin K is removed from the blood during dialysis. 3. Absorption in the intestines is impaired. 4. The analysis method (dephosphorylated-uncarboxylated MGP) is influenced by the patients' protein intake. The purpose of the fifth trial is to investigate solutions to improve the vitamin K status of hemodialysis. One is to improve vitamin K status through diet with an increased focus on foods with high concentrations of vitamin K while considering phosphate, potassium and fluid restrictions. The second is to increase vitamin K status through a daily supplement of 360µg Menakinon-7.
In chronic kidney disease, ESAs (Erythropoiesis-stimulating agents) are used to treat anemia. This anemia is due to decreased renal production of erythropoietin (EPO), a hormone that stimulates the production of red blood cells in the bone marrow. Treatment of anemia increases survival, decreases morbidity and improves quality of life and exercise tolerance. Self-administration of ASE has been encouraged for many years, notably with pens for injection, but only few patients are educated in the injection technique. The investigators therefore wish to lead a study in the Nephrology department of Rennes University Hospital to educate the patient, or his or her spouse, on ESA injections during hospitalization, in order to empower the patient in his care, and with the second aim of reducing the costs of chronic renal insufficiency.
Many studies have been conducted to identify therapeutic strategies to modulate inflammation and oxidative stress, complications that contribute to the increased morbidity and cardiovascular mortality in patients with chronic kidney disease (CKD). Among several non-pharmacological strategies, the use of bioactive compounds has emerged as a potential approach to reduce these complications in CKD patients. In this context, turmeric/curcumin may have positive consequences in terms of cardiovascular and nephroprotection because of its antibacterial, antiviral, anti-inflammatory and anti-oxidative effects. The aim of this study is the role of curcumin as a nutritional strategy to reduce cardiovascular risk factors as inflammation and oxidative stress in CKD patients.
This study examines whether a safety-net primary care CKD registry directed at the entire primary care team can enhance the delivery of guideline concordant CKD care, including BP control, ACEi/ARB use and albuminuria quantification.
Hyperphosphatemia is a severe complication to chronic kidney disease (CKD) and is associated with increased risk of vascular calcification, cardiovascular morbidity and mortality. Early dietary intervention and improvement in dietary therapy might optimally reduce cardiovascular complications. For this purpose the investigators investigated patients with CKD stage 3-4, the participants dietary habits, developed a New Nordic Renal Diet and investigated the short term effect on phosphorus homeostasis.
This study will test the effectiveness of mailed, smartphone urinalysis kits to improve albuminuria screening compliance and detection of albuminuria.
The investigators are studying the feasibility, acceptability, and outcomes of an intervention called Enhanced Dialysis Education (EDU) Intervention. CKD-EDU is a palliative care-based dialysis decision-making intervention that involves educating patients and caregivers about dialysis and engaging them in shared decision-making. Half of the enrolled patients will receive CKD-EDU and the other half will receive Usual Care.
The main study aim is to quantify the agreement between the analytical results provided by two third generation and two second generation Parathyroid hormone (PTH) assays. The primary comparison will be performed between the second-generation PTH assay"Intact PTH assay" from Siemens Healthcare Diagnostics Inc. and the third-generation PTH assay "biointact (1-84)" from Roche Diagnostics in terms of a Bland-Altman analysis. Several studies have evaluated the correlation between various PTH assays at a single time-point, but no previous study has tested the hypothesis that longitudinal changes in PTH levels, which are important for making treatment decisions, can be monitored by several PTH assays alike. To this aim, the key secondary objective is to analyze the longitudinal variance in PTH over the course of 1 year, using each of two assays of the second and third generations, respectively. Other secondary objectives include determining changes in serum phosphate, serum calcium, fibroblast growth factor 23 (FGF23), with respect to treatment decisions. For clinical applicability of the results to be obtained here, an important goal of the present study will be not to influence treatment decisions, which will remain independent of the study investigators, at the full responsibility of the hemodialysis physicians. At every quarterly blood draw over the course of one year, the investigators will freeze the serum from 100 patients, and at the end of 4 quarters the investigators will analyze PTH-levels using the following assays: Intact Parathyroid Hormone (Advia Centaur, Siemens Healthcare), PTH-Intact (Cobas, Roche), PTH (1-84) - The agreement between the PTH assays will be analyzed at baseline, as well as at the subsequent quarterly evaluation time-points by Bland-Altman analysis and complemented by Passing-Bablok regression. The longitudinal changes in PTH will be displayed graphically and analyzed by estimating the within-patient variance across time, the between patient variance at each time-point as well as effects on the mean log-PTH level due to course of disease and therapeutic interventions from a linear mixed model.
Arterial calcifications (AC) are constant lesions in patients with Chronic Kidney Diseases (CKD). Renal transplantation would reduce their progression compared to dialysis. AC pathophysiology is a complex and finely regulated process that involves many local and systemic factors, both pro- and anti-calcification. The progression of the CKD is accompanied by an increase in phosphate levels as the renal excretion capacity of inorganic phosphates (Pi) decreases while their digestive absorption remains unchanged. Hyperphosphatremia is a well-identified calcifying factor contributing to ACs in the CKD. On the other hand, pyrophosphate (PPi) is an anti-calcifying factor from the hydrolysis of extracellular ATP by ectonucleotidases. While there are many factors that may contribute to a protective effect against AC progression of renal transplantation, no study has been yet analysed the role of PPi. Plasma concentration of PPi is decreased in dialysis patients compared to non-kidney failure patients. The main objective of this monocentric, prospective and interventional pilot study will be to compare the progression of CA and [PPi]pl between a group of renal transplant patients over the past 24 months and a group of dialysis patients over the same period of time. The secondary objectives will be to compare the progression of ACs and the ratio[PPi]pl/[Pi]pl between transplanted and dialysis patients. Transplanted patients will be included within 24 (±3) months of transplant. Dialysis patients will be included at 24 (±3) months of the CT scan performed during the pre-transplant check-up. At inclusion, all patients will benefit from a CT scan without injection and a plasma dose of PPi, Pi and other factors involved in controlling calcification.
For hemodialysis subjects not receiving ESAs with anemia associated with chronic kidney disease, evaluate Hb correction and maintenance effect and safety of MT-6548.
