Filter by: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.
The purpose of this study is to examine the colchicine concentration before and after the administration of rifampicin.
The purposes of this study are: (1) to compare the body composition, physical activity, physical function, and quality of life between patients with and without CKD after CABG; and (2) to analyze the relationships among body composition, physical activity, and physical function in this population. It is expected that patients after CABG with CKD have the worse body composition, physical function, and quality of life than patients after CABG without CKD; and patients with higher physical activity levels have the better body composition, physical function, and quality of life.
Vitamin D deficiency is common in the general population and more common in children with chronic kidney disease. Vitamin D is very important for bone health, especially in children with chronic kidney disease. To date, several studies using different doses of vitamin D have been tried to correct vitamin D deficiency, but none has been completely successful. The investigators are comparing two different doses of vitamin D to determine which one is more effective at correcting and maintaining normal blood levels of vitamin D. The investigators hypothesize that a higher percentage of children receiving a higher dose of vitamin D will be vitamin D replete at the end of 6 months. This study will enroll 80 children 9 to 18 years old who have chronic kidney disease (CKD) and can take pills. They will be enrolled from Chronic Renal Insufficiency Clinic, the Hemodialysis Unit, Peritoneal Dialysis Clinic and Transplant Clinic at Children's Healthcare of Atlanta.
