Active clinical trials for "Kidney Diseases"

Diurnal variations in the cardiovascular system apparent in healthy individuals, are different in chronic kidney disease patients. Therefore, diurnal variations in arterial stiffness may also differ in chronic kidney disease patients. This study aims to identify and evaluate diurnal variations in arterial stiffness in chronic kidney disease patients and compare them to those in age matched healthy controls.

This study is a multicenter, non-randomized, retrospective study to collect long term (5 years post-transplant) clinical outcome data to test whether the results of the noninvasive immune monitoring test strategy performed in the parent study (CTOT-01, NCT00308802) in first six-month post-transplant is predictive of 5-year outcomes. Each center will complete a retrospective chart review for the data on patient survival, graft survival and renal function.

This pragmatic cluster randomized controlled trial will test the impact of feedback and a toolkit aimed at improving the management of chronic kidney disease (CKD) in the primary care setting. This trial will use family physicians in Ontario participating in the Electronic.

The SCOPE study is an observational, multicenter, prospective cohort study aimed at evaluating a 2-year screening programme for CKD in a population of older patients, aged 75 years or more, in seven European Countries, in an attempt to investigate whether and to which extent currently available screening methods may identify older people at risk of worsening kidney function.

PHYSALYS is an observational multicenter study. It's an analytical study comparing 2 groups: patients exposed to physical activity and unexposed. The main objective of the study is to compare the evolution of glomerular filtration rate at inclusion and 12 months later between patients practicing physical activity and patients not practicing. If necessary, the renal disease-related complications, which are not influenced by physical activity: (type of kidney disease, age and tobacco), would be taken into account. TIRCEL patients with chronic kidney disease (CKD) at stages 3, 4 or 5 can be included in the study. Their serum creatinine data, 12 months prior to inclusion, is collected retrospectively. Patients are followed in the trial during 12 months. To evaluate physical activity, patients respond to Global Physical Activity Questionnaire 2 (GPAQ2) at inclusion and 12 months later. During this 12 months period, the same biological data are collected prospectively.

Patients undergoing haemodialysis present a decrease in physical function, but little is known about the rate at which function decreases. The purpose of this study is quantifying the nature and degree of functional deterioration experienced by stage 5 chronic kidney disease patients during a six month period of maintenance haemodialysis therapy.

An arterio-venous fistula is a surgical procedure that supports access for people undergoing hemodialysis (HD) for End Stage Renal Disease (ESRD). This observational pilot study seeks to better understand the factors that contribute to the successful maturation of an arterio-venous fistula. A primary aim of this study is to see if endothelial function (the biochemical events initiated by cells lining the arteries) is associated with successful maturation. Other aims include determining if pro-inflammatory markers in the blood or evidence of gene expression are associated with successful maturation.

The aim of this clinical investigation is to prove that the seca mbca detects dialysis patients with abnormal water distribution correctly. Abnormal high water distribution is defined as more than 2 liters of Total Body Water (TBW) above a normal value range. TBW and Extra Cellular Water (ECW) are calculated with prediction equations for healthy subjects generated in BCA-01. The results are compared with TBW and ECW ascertained by dilution methods as standard reference methods. The Bioelectrical Impedance Analysis (BIA) method should be evaluated to the accuracy of the absolute measurement of the volume state of dialysis patients (euvolaemic and hypervolaemic) based on a single measurement.

In clinical practice the 24-hour creatinine clearance is often used to obtain an impression of renal function. However, the glomerular filtration rate is considered to be the best indicator of renal function. For practical and financial purposes, GFR is often estimated by means of serum creatinine based equations. These equations are also used in internation guidelines to define and classify chronic kidney disease. Therefore, accurate creatinine measurements are important to make reliable estimates of renal function. However, previous research has revealed a large variability in creatinine measurements using different measuring methods. In this study the investigators aim to establish the degree of variability in different methods to measure creatinine in a heterogenous group of Caucasian people with and without renal function loss and the influence of this variability on renal function estimating equations and the 24-hour creatinine clearance.
