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.
GSK1278863 is an orally available, hypoxia-inducible factor - prolyl hydroxylase inhibitor, currently being investigated as a treatment for anemia associated with chronic kidney disease. GSK1278863 has been given as a once daily regimen in clinical studies to date. However, physicians in countries that use a three-times weekly hemodialysis schedule prefer to give the anemia medicine at the same time as the dialysis session. This study will test how well GSK1278863 can maintain hemoglobin levels when given three-times weekly, for 29 days. This study will describe the relationship between hemoglobin and GSK1278863 given three-times weekly. The data from this study will allow for conversion of once daily doses to three-times weekly doses.
A prospective, multisite study to evaluate the Impact of Measles, Mumps, Rubella and Varicella ProQuad® vaccination in pediatric patients 6-24 months of age who are being considered and/or evaluated for any solid organ transplant (heart, liver or kidney)
During the 2013-2014 influenza season, CKD patients undergoing HD participated in the study. The patients were randomized into two groups (MF59-adjuvanted vaccine group or non-adjuvanted vaccine group) and were immunized with the respective vaccine. Sera were collected prior to vaccination and at 1and 6 months post vaccination. Levels of hemagglutination inhibition (HI) antibodies were measured.
Randomized two-arm study examining 90 day primary patency of two FDA-approved tunneled dialysis catheters.
Background: In 2010, approximately 39000 Canadians had end-stage renal disease (ESRD), and the prevalence rate of dialysis has increased by 189% over the past 2 decades. The annual mortality rate remains high at ~15%, and cardiovascular events are the leading cause of death. Intensification of conventional dialysis schedules has been the major focus in recent years. Currently, most Canadian dialysis patients receive conventional in-center hemodialysis (CHD), which is administered as a 3-4 hour session 3/week. Recent research has focused on home nocturnal hemodialysis (8 hours of hemodialysis at home for 5-6 nights/week), which may have substantial cardiovascular benefits, including regression of left ventricular (LV) hypertrophy, improved LV ejection fraction and enhanced blood pressure control. Nevertheless, this dialysis modality is only feasible in a highly selected minority of ESRD patients who can self-manage their dialysis treatment at home. In-center nocturnal hemodialysis (INHD), administered as 7-8 hours of hemodialysis in hospital for 3nights/week, represents a promising and practical alternative for many dialysis patients. In a Canadian Institutes for Health Research (CIHR) supported cohort study, the investigators have recruited 67 patients and have completed 1-year follow-up. There is a compelling need for longer-term follow-up, since all the published randomized controlled trials are of short duration (6-12 months), while renal replacement therapy is a life-long treatment. Furthermore, the observed large variability of cardiac remodeling in individual ESRD patients remains poorly understood. Therefore, the current study is an extended follow-up phase (5 years from enrollment) on the completed 1-year follow-up period and the purpose of this study is to objectively evaluate the long-term effects of more intensified hemodialysis treatment which the INHD modality offers. Need for Long-term and Generalizable Data: In contrast to the seminal Alberta trial which showed a significant LV mass reduction with home nocturnal hemodialysis, the recently reported Frequent Hemodialysis Network Nocturnal Trial demonstrated only a trend toward reduction in LV mass. It is likely that the highly selected participants, inadequate trial power and duration (12 months) account for the observed results. Currently, it is unknown whether INHD, which is less intensive but more feasible for most ESRD patients, is associated with similar cardiovascular benefits in the long term. Objective: 1. To determine the long-term effects of INHD on (i) LV mass; (ii) global and regional LV systolic and diastolic function; (iii) myocardial tissue characteristics; (iv) left atrial structure and function; (v) selected cardiovascular biomarkers in ESRD patients. 2. To examine the determinants and mechanisms of cardiac remodeling in ESRD Hypothesis: Conversion to INHD is associated with sustained improvements in cardiovascular structure and function, as compared to conventional hemodialysis (CHD) in patients with end-stage renal disease (ESRD). Study Design and Population: This will be a 2-centre, prospective, longitudinal cohort study of 67 adult ESRD patients (INHD subjects and CHD controls) enrolled in the original study. All eligible participants who provide consent will undergo cardiac Magnetic Resonance Imaging (MRI) examination and bloodwork at 5 years since enrollment in the study. Other follow-up procedures include the following -electrocardiogram, transthoracic echocardiogram, ambulatory blood pressure monitoring, lateral x-ray of the aorta, and completion of questionnaires. Outcome: The primary endpoint is the change in LV mass over 5 years, as measured by cardiac MRI. Secondary endpoints include LV size, global and regional diastolic and systolic function, left atrial size and function, changes in myocardial tissue characteristics, blood pressure, serum troponin, norepinephrine, Brain Natriuretic Peptide (BNP), high sensitivity C-Reactive Protein (hsCRP), interleukin-6, matrix metalloproteinases, fibroblast growth factor-23, fetuin-A, transforming growth factor-beta, connective tissue growth factor, clinical events, and quality of life. Significance: The provision of an enhanced dialysis regimen has emerged as the most promising avenue through which to modify the dismal cardiovascular outcomes in patients receiving chronic hemodialysis. INHD represents a means of administering such therapy to a broad spectrum of dialysis patients for whom home therapies would not be feasible. This study will be the first to precisely define the long-term cardiac effects of intensified dialysis and to elucidate the mechanisms of cardiac remodeling in ESRD, using cardiac MRI and other novel biomarkers. These important observational findings may have a major impact on the optimal management and outcome of ESRD patients in the real world.
The health care burden of CKD is substantial and growing with 10-15% of the population affected in both developed and developing countries. It is well established that CKD is associated with systemic inflammation, which promotes cardiovascular disease and body wasting. However, causal therapies to treat systemic inflammation, and treat its adverse consequences remain sparse. As kidney function declines in all forms of CKD, oxalate levels increase in the plasma, leading to increased systemic exposure to oxalate and consequent tissue injury. Work from the investigators has shown that elevated plasma oxalate levels activate the NLRP3 inflammasome which in turn leads to the processing and release of cytokines. The investigators seek to test the hypothesis that oxalate contributes to the systemic inflammation observed in patients with end-stage renal disease (ESRD). The investigators plan to define the association between plasma oxalate levels and signs of systemic inflammation in patients on hemodialysis. In a second step the investigators will examine whether hemodiafiltration lowers plasma oxalate more efficiently than hemodialysis and reduces signs of systemic inflammation. Confirmation of the hypothesis may lead to the identification of oxalate as a novel therapeutic target for interventional trials aimed at reducing plasma oxalate in patients with ESRD.
