Active clinical trials for "Kidney Diseases"

The purpose of this study is to determine the durability of seroprotection of HEPLISAV™ and Engerix-B® and the number of injections of each vaccine needed to maintain seroprotection in a cohort of chronic kidney disease (CKD) patients over time.

The investigators aimed to study the effect of prohepcidin levels on hematologic parameters and inflammatory markers in non-diabetic uremic patients. The investigators selected three groups of patients: Hemodialysis group, peritoneal dialysis group and the group with stage 4 chronic kidney disease. A control group was formed from healthy volunteers also. Each group has been planned to be formed of about 25 patients. Diabetic patients were excluded. Prohepcidin, hsCRP, IL-6, fibrinogen have been planned to be studied besides other routine biochemical analysis including hematological ones.

Sleep disorders (SD) are common in adults with Chronic Kidney Disease (CKD) on dialysis with a reported prevalence of 60-80%. To date three studies have reported on SDs in children with CKD but these have all been based on questionnaire data alone. The findings were not confirmed with polysomnograms (PSG), the gold standard to diagnose SD, or actigraphy, a validated tool to assess the sleep/ wake cycle over a prolonged period in the home. This is highly relevant given the poor sensitivity and specificity of even validated questionnaires alone. The effect of untreated pediatric SD is pervasive. This study will provide the first objective assessment of SDs using PSGs in children with severe CKD, both on and off dialysis. Therefore, we will recognize and when possible treat SD in this severe CKD cohort potentially contributing to their immediate management (eg improved control of hypertension, improved school performance), while improving their Quality of Life (QOL) and helping ensure they achieve their full potential.

The primary objective of this study is to assess in a post-approval clinical setting the safety profile of sevelamer carbonate (Renvela®) tablets and powder in adult hyperphosphataemic chronic kidney disease (CKD) patients not on dialysis with serum phosphorus ≥1.78 mmol/L. Patients will be treated in accordance with the Renvela® Summary of Product Characteristics (SmPC) and followed according to the investigator's standard clinical practice management. Each patient will be followed up for 12 months or up to the time they start dialysis, whichever occurs first.

Contrast-induced nephropathy (CIN) is a well-recognized complication of radiographic contrast administration and is associated with increased short- and long-term mortality. Previous strategies including forced diuresis with diuretics or mannitol, intravenous administration of fenoldopam or dobutamine, and postprocedure hemodialysis to prevent CIN have been largely unsuccessful. In addition, the use of N-acetylcysteine to prevent CIN has yielded conflicting outcomes. A review of a large insurance database and retrospective study have shown that statins therapy is associated with a lower incidence of CIN after percutaneous coronary intervention. The preventive effect of statins on CIN may be attributed to direct pleiotropic effects on the vascular wall such as improvement of endothelial dysfunction, anti-inflammatory or anti-oxidative effect. However, recent randomized trial could not demonstrate the preventive effect of statin on CIN in patients with chronic kidney disease. Thus, we will investigate the preventive effect of pitavastatin on CIN in patient with renal dysfunction undergoing coronary angiography or intervention.

The purpose of the study is to monitor initiated Diafer® therapy administered according to hospital practice and the product labeling in routine clinical practice in haemodialysis patients with Chronic Kidney Disease.

This study is being implemented for 3 aims. The first has been to conduct a systematic literatures review on CKD intervention models and their effectiveness. Findings have been adopted in our intervention program. The second purpose is to establish a practical management model or an intervention model for CKD patients and high risk population with the 18-month of follow-up.In the third year, we will use social perspective point to evaluate the costs and the benefits of intervention.

Ferric hydroxide adipate is a ferric iron supplement containing iron hydroxide and a dietary organic acid that was developed at MRC Human Nutrition Research. We aim to determine if the ingestion of ferric hydroxide adipate with food induces a reduction in urinary phosphate concentration, compared with the administration of placebo plus the same food on a different occasion. We hypothesise that ferric hydroxide adipate binds some phosphate ions in the gastrointestinal tract, which prevents part of the phosphate load in a meal from being absorbed. On another visit, calcium will be given with the same food, as a positive control, since this element is well known to restrict dietary phosphate absorption through the formation of insoluble calcium phosphates in the gut lumen. We will compare urinary phosphate concentrations after co-ingestion of the calcium salt and food versus urinary phosphate following ferric hydroxide adipate and the same food. Additionally, the calcium data will be compared with placebo data, since a significant reduction in urinary phosphate concentrations after calcium treatment will confirm the suitability of the study design. Finally, iron absorption from the ferric hydroxide adipate treatment will be determined by labelling this preparation with 58Fe and measuring day 14 erythrocyte 57Fe:58Fe. The study design is: Three-way cross-over volunteer absorption study. Volunteers will not be told which treatment they receive (placebo, ferric hydroxide adipate, or supplemental calcium). Researchers co-ordinating the study on a day to day basis will be aware of treatment allocation, but analysts will not be told which samples correspond to which treatments.

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

The aim of this study is to investigate the impact of renal function and dialysis techniques on the percentage of senescent T lymphocytes.
