Compared to conventional hemodialysis (HD), on-line hemodiafiltration (OL-HDF) achieves a more efficient removal of uremic toxins and reduces inflammation, which could favourably affect nutritional status. The aim of this study was to evaluate the 1-year effect of OL-HDF on nutritional status and body composition in prevalent HD patients.
Background: Calcimimetic therapy has been shown to reduce systemic FGF23 levels, which themselves are associated with left ventricular hypertrophy (LVH) in chronic kidney disease (CKD). Methods/design: This is a randomized multicenter trial in which the effect of etelcalcetide in comparison to alfacalcidol on LVH and cardiac fibrosis in hemodialysis patients with secondary hyperparathyroidism (sHPT) will be investigated. The investigators will perform a comparative trial testing etelcalcetide vs. alfacalcidol treatment on top of conventional HPT therapy for 12 months. A total of 62 hemodialysis patients with sHPT and LVH will be enrolled in the study. After a washout of all calcimimetic and vitamin D treatment, subjects will be randomized at 1:1 ratio to either etelcalcetide or alfacalcidol. The participants will undergo cardiac imaging consisting of cardiac resonance imaging (cMRI) and strain echocardiography before and at baseline and one year. Etelcalcetide or alfacalcidol will be administered intravenously three times per week following chronic hemodialysis treatment. The primary end point will be a change in left ventricular mass index (LVMI) measured in g/m2. As secondary end points the changes in left atrial diameter (LAD), cardiac fibrosis, wall motion abnormalities and left ventricular function, changes in serum FGF 23 and soluble Klotho levels as well as changes in proBNP as well as pre- and postdialysis troponin T (TnT) levels will be determined. Additionally a quantitative analysis of the treatment influence on the individual metabolites of the renin-angiotensin-aldosterone system (RAAS) will be performed using mass spectrometry ("RAAS fingerprint").
Remote patient monitoring is a potential component for the management of chronic conditions that may provide reliable and real-time physiological measurements for clinical decision support, alerting, and patient self-management. The purpose of this study is to evaluate an UHN-built remote monitoring system for patients with complex chronic conditions called Medly.
The investigators aim to evaluate the feasibility of a resistance exercise training program among individuals with CKD and its impact on endothelial and vascular function.
In post-dilution haemodiafiltration only synthetic membranes have been used to date. The allergy problems described with these membranes require the development of other membranes capable of performing this treatment. We describe in vivo performance and behaviour of an asymmetric cellulose triacetate(ATA™) membrane, to identify its depurative effectiveness and ease of use in clinical practice, as well as evaluate its biocompatibility in a single haemodialysis session (acute biocompatibility) and after one month of treatment (chronic).
This study will use an adapted education worksheet to support patient-centered chronic kidney disease (CKD) communication, shared decision making, and patient engagement and will test its impact on intermediate patient modifiable characteristics in a primary care practice with patients who have pre-dialysis CKD. The study team will enroll up to 100 patients with chronic kidney disease (CKD) from a primary care clinic to start. Patients will receive the intervention, which consists of the physicians using the education worksheet during appointments with patients, and patients and providers will complete surveys about its use and to measure impact on knowledge and other areas related to patient outcomes. Once initial user testing is complete, the study team plans to submit an amendment to expand on this trial and incorporate comparison sites. This will be submitted and receive IRB approval prior to participant involvement. The study hypothesis is that patients who receive the intervention will have greater knowledge about their CKD diagnosis, higher satisfaction with provider communication, and higher scores related to managing CKD to keep themselves healthy compared to control populations.
This study is looking to improve the safety of patients with chronic kidney disease via education provided on a mobile tablet. This study will additionally examine if electronic tools, such as mobile tablets, can help.
The purpose of this study was to assess the handgrip strength; fine motor skills; and hand sensitivity of Brazilian children and adolescents with Chronic Kidney Diseases (CKD). The sample was composed by 42 children and adolescents, 21 on hemodialysis (group A) and the other 21 acted as the control group (group B). The performance of both groups was compared. The outcome measures included Jebsen-Taylor Hand Function Test, the Semmes Weinstein monofilaments test and Jamar Dynamometer.
The most common co-morbidity accompanying Chronic Kidney Disease (CKD) is hypertension, which appears in approximately 80% of all patients with renal dysfunction, whereas its prevalence in general population is remarkably lower appearing in approximately 30% of adults.Defining hypertension in ESRD patients under maintenance dialysis is a challenging procedure. Ambulatory blood pressure monitoring (ABPM) is considered the "gold standard" for the diagnosis of hypertension in hemodialysis patients over the last years. The major pathophysiologic mechanism underlying hypertension development in patients with ESRD under hemodialysis is water and sodium overload. Identifying an accurate and objective method of dry weight evaluation has been a matter of intensive nephrology research for more than two decades. Assessment of the water balance in hemodialysis patients on the basis of common clinical criteria (e.g. leg or face swelling or signs of lung congestion) is a subjective method with limited reliability, despite its widespread use. Recently, a novel technique has been developed to quantify water excess by conducting an ultrasound lung scan. Pilot studies have shown significant changes in lung water in hemodialysis patients according to body weight changes during interdialytic days and dialysis sessions. Moreover, results from previous studies indicate significant benefits from dry weight probing with regards to blood pressure (BP). The clinical application of a lung-ultrasound-based volume control strategy in hemodialysis patients is currently being tested by the randomized study entitled "Lung water by ultrasound guided treatment to prevent death and cardiovascular complications in high risk end stage renal disease patients with cardiomyopathy (The LUST Study)". This clinical trial aims at evaluating whether the use of the number of US-B lines could be used as a biomarker to guide a per-protocol intensification of ultrafiltration (UF) in order to reduce volume overload, improve cardiac function and prolong survival. Cardiovascular disease in patients with CKD is attributed to a spectrum of structural and functional alterations of the large and the small branches of the arterial tree. The most important process in patients with advanced CKD is that of arteriosclerosis, which is developed in parallel to atherosclerosis and is typically associated with impaired cushioning function of the aorta and the large conduit arteries. Accelerated arterial stiffening is involved in the development of isolated systolic hypertension, left ventricular hypertrophy (LVH) and congestive heart failure (CHF), which predispose to arrhythmias and sudden cardiac death. In the context of the phenomenon of "aortic-to-brachial BP amplification", systolic BP (SBP) and pulse pressure (PP) conventionally measured at the level of brachial artery are higher than the relevant pressures in the ascending aorta. Due to extreme elevation of arterial stiffness, BP amplification is disturbed in patients with ESRD. Prospective cohort studies have demonstrated that elevated central PP, wave reflections and arterial stiffness, as well as, reduced PP amplification represent strong and independent predictors of all-cause and cardiovascular mortality in hemodialysis patients. On this basis, estimation of central BP indices appears as an important tool towards optimisation of cardiovascular risk stratification in ESRD as well as in other diseased populations. Until recently, available devices for ABPM evaluated BP levels only at the level of brachial artery. The newly developed Mobil-O-Graph NG (IEM, Stolberg, Germany) provides the ability to monitor central aortic pressure and indices of vascular resistance, such as wave reflections (augmentation index, AIx) and arterial stiffness (pulse wave velocity, PWV).This device has recently been validated in hemodialysis patients and showed comparable performance with the widely used tonometric SphygmoCor device (ArtCor, Sydney, Australia). Accumulated evidence over central BP and PWV in hemodialysis patients derives mostly from studies that included only static pre-dialysis and post-dialysis measurements. However, variations of BP levels during intra- and interdialytic intervals combined with the superiority of aortic BP measurements, as analysed above, indicate that ambulatory monitoring of central BP is the best available method. This study aims for the first time to evaluate the outcome of a treatment strategy for dry weight probing, based on volume overload quantification with lung ultrasound, on 48-hour peripheral systolic BP, aortic BP and arterial stiffness in hemodialysis hypertensive patients. This is a Lust Sub-Study. Additional information can be found at: NCT02310061.
