Filter by:The purpose of the study is to learn more about how treatment with vitamin D can affect iron metabolism and blood levels of two hormones that control iron levels, hepcidin and hemojuvelin in people with chronic kidney disease (CKD). Iron is an essential mineral which is a major component of proteins that carry oxygen in the blood. Problems with iron metabolism can lead to low blood levels (anemia), which can commonly happen in people with CKD. New research over the last decade has uncovered a new hormone called `hepcidin', which is made in the liver and released into the blood. Hepcidin controls how much iron is in the blood by preventing the absorption of iron from food. Blood levels of hepcidin C are found to be high in people with CKD, and a recent small study in people with normal kidney function showed that treatment with vitamin D decreased hepcidin levels. Another protein, known as `hemojuvelin', has been recently discovered and is also thought to control the amount of iron in the blood. The relationship between vitamin D and hemojuvelin has never been studied before. In this study, investigators would like to examine the effects of vitamin D on iron metabolism and blood levels of hepcidin C and hemojuvelin in individuals with CKD.
Cardiovascular disease (disease of the heart and blood vessels) is one of the leading causes of death in Canada. It also carries a financial burden on the Canadian economy with a yearly cost close to $21 billion divided between loss of productivity and healthcare costs. The majority of cardiovascular disease cases (90%) are caused by factors that can be controlled and modified. These factors include high blood pressure, high cholesterol, diabetes (high blood sugar), tobacco smoking, unhealthy diet, obesity, physical inactivity and high alcohol consumption. Such factors are very common and not very well controlled and so individuals who have any of these factors would be at risk of having cardiovascular disease. As such controlling these factors will reduce the risk of having cardiovascular disease and improve the individuals' quality of life. Pharmacists frequently work with patients and their family doctor to provide cardiovascular care. Having a pharmacist involved in cardiovascular care may help patients with cardiovascular disease or at risk of having the disease because they are more accessible and may have more opportunities to educate people about cardiovascular medications. This might lead to better prevention and control of cardiovascular disease. Purpose: The research study will assess if a community pharmacy cardiovascular risk reduction intervention can help reduce cardiovascular risk. Procedure: If the individual has an elevated blood pressure, cholesterol, blood sugar, waist circumference or body weight or is physically inactive, have an unhealthy diet, a smoker or taking medications for any of the previously mentioned conditions, the pharmacist will assess the cardiovascular disease risk [risk of having a cardiovascular event (e.g. heart attack or a stroke)] using a computer program. If the individual is at high risk s/he will be asked to take part in the study. If the individual agrees to take part in the study s/he will be randomly assigned to either the Usual Care Group or the Advanced Care Group. All participants have an equal chance of being assigned to either group. If assigned to the Usual Care Group, the individual will receive the care and services that would normally be provided by the pharmacist. At 3 months, the pharmacist will see the individual who will be offered the Advanced Care at that time. If assigned to the to Advanced Care Group, the individual will be asked to meet with the pharmacist every 3-4 weeks over a 3 month period. During these meetings, the pharmacist will conduct an assessment that may include blood pressure, waist circumference, height and weight measurements and talk to the individual about their cardiovascular risk and medications. The individual and the pharmacist will come up with a plan for how to try to lower his/her cardiovascular risk. The pharmacist will discuss this plan with their family doctor. The individual will be asked to conduct some laboratory tests before the 3 months visit; these tests may include HbA1c (a blood test to measure blood sugar control over the last 3 months) and cholesterol to assess the effect of the intervention on cardiovascular risk.
If primary health-care officers and Villages Health Volunteers (VHVs) be trained to render proper CKD care, it is interesting if their intimate relationship and commitment to their responsible village households will result in better outcomes when compared with the conventional care model as mention above. In this project, we plan to compare the effectiveness of a conventional care program against an integrated multidisciplinary CKD care program provided by nephrologists in conjunction with well-trained paramedical personnel and VHVs on CKD progression.
This is a single site study designed to evaluate the FAST mGFR Test™ in healthy adult volunteers, patients with varying degrees of chronic kidney disease (CKD), and patients with acute kidney injury (AKI).
The primary objective is to assess the effects of colestilan on the pharmacokinetic profile of candesartan cilexetil when administered at the same time as, 1 hour before, and 3 hours after the first daily dose of colestilan administered at doses of 5 g three times daily compared to administration of candesartan cilexetil alone, in healthy subjects.
Longitudinal cohort of patients with chronic kidney disease followed in 3 kidney centers in Ontario. The goal is to determine whether and how rates of renal disease progression are affected by inflammatory markers, FGF23 levels, and genetic polymorphisms
Hypovitaminosis D is highly prevalent among patients with chronic kidney disease, especially in those undergoing dialysis. The loss of protein to the dialysis solution seems to contribute significantly to the reduced serum levels of vitamin D in these patients. As a result of the disease and the dialysis procedure, there is high prevalence of chronic inflammation and high risk of infections. There is evidence in other populations, that vitamin D has immunomodulatory effects by stimulating the production of cathelicidin, an antimicrobial peptide and suppressing the production of proinflammatory cytokines. Thus, this study aims to investigate the effects of cholecalciferol supplementation on immunological markers in patients in hemodialysis and peritoneal dialysis with hypovitaminosis D . This is a randomized, double-blind, placebo-controlled trial in which patients who have vitamin D deficiency [25 (OH) D <20 ng / mL] will be allocated to the intervention group (cholecalciferol) or control (placebo). Patients will receive supplemented 100,000 IU / week cholecalciferol a period of 12 weeks. Before and after the intervention will be determined 25(OH)D, cathelicidin, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and C-reactive protein serum. In monocytes, we will evaluate cathelicidin, IL-6 and TNF-α, 25(OH)D receptor and α 1-hydroxylase enzyme expression.
Progressive renal impairment in chronic kidney diseases (CKD) may cause inability to excrete phosphate load, thus leading to the typical abnormalities of the mineral metabolism, such as increased phosphate and reduced calcium levels, 1,25- dihydroxyvitamin D deficiency and secondary hyperparathyroidism (HPT). Treatment with vitamin D analogues and/or phosphate binders ameliorates these abnormalities that are also associated with accelerated renal disease progression and increased cardiovascular risk. However in a post-hoc analysis of 331 patients with proteinuric chronic nephropathies included in the Ramipril Efficacy In Nephropathy (REIN) trial, increasing serum phosphate levels at inclusion, even within the normal reference range, were associated with an incremental risk of progression to End Stage Renal Disease (ESRD). Moreover, increasing levels of serum phosphate were associated with a progressively decreasing protective effect of ramipril therapy against progression to ESRD, to the point that the benefit of Angiotensin-Converting-Enzyme (ACE) inhibition was almost fully lost among patients with serum phosphate levels exceeding 4.5 mg/dL. This finding provided convincing evidence that phosphate plays a direct pathogenic role in patients with progressive nephropathies and that excess phosphate exposure may limit or even blunt the renoprotective effect of ACE inhibitor therapy in this population. Sevelamer carbonate is a newly approved phosphate binder for chronic kidney disease (CKD) patients not yet on maintenance dialysis. Treatment with Sevelamer, in addition to correct hyperphosphatemia, was also found to ameliorate abnormalities of the mineral metabolism associated with accelerated renal disease progression and increased cardiovascular risk. Moreover, Sevelamer therapy reduces proteinuria in an animal model of uremia, an effect that in the long term might translate into significant renoprotection. These findings suggest that serum phosphate might be a specific target for renoprotective therapy in CKD patients and provide the background for randomized clinical trials to formally test whether reducing phosphate exposure by phosphate binding agents may serve to optimize the renoprotective effect of RAS inhibition in this population. Thus, whether phosphate reduction by Sevelamer carbonate therapy may have a specific antiproteinuric effect in humans with chronic nephropathies and residual proteinuria despite optimized RAS inhibitor therapy is worth investigating.
Increasing sodium intake raises blood pressure. And high salt intake could hinder the management of chronic disease. Much previous research has confirmed that dietary habits are affected by economic status. So we compared sodium intake with economic status. We investigated the prevalence, extent and management, and the relevance of sodium intake with income level.
The EPOCH-RRT study seeks to fill knowledge gaps by gaining more understanding of chronic kidney disease (CKD) patients' priorities; assessing the comparative benefits of hemodialysis (HD) versus peritoneal dialysis (PD), with respect to these priorities; and providing tailored information to assist patients with identifying the best dialysis modality fit for their own unique circumstances and perspectives. The outcomes most relevant to patients ("patient-centered") extend beyond those traditionally assessed in clinical research, with the relative importance varying across patient groups. A tailored decision aid based on these findings can improve patient decision-making processes regarding choice of dialysis modality.
