Active clinical trials for "Kidney Failure, Chronic"

Hypothesis: The use of a program that assists with selection of the appropriate number of phosphate binders for a meal based on patient specific factors will result in improved serum phosphate control, a reduction in overall number of phosphate binders used and enhanced patient satisfaction. Primary Aim: To determine if teaching patients to use a 'phosphate counting' program installed on an iTouch that selects the appropriate amount of phosphate binder to be taken with each meal is associated with better phosphate control than usual care. Research Plan: There will be 3 phases to the study. Phase 1: Recruitment of 60 peritoneal dialysis (PD) patients. The information generated from this phase will be used to develop the iTouch program for phosphate counting and matching binder number. Phase 2: iTouch program once developed will be pilot tested on a convenience sample of 10 PD patients and modified if required. Phase 3: Randomized controlled trial of 92 PD patients to determine if using the iTouch phosphate counting program reduces serum phosphate compared to controls. Success would be based on seeing a statistically significant difference in serum phosphate as expected from our sample size calculation

Peritoneal fibrosis is one of the major causes of technical failure in patients on peritoneal dialysis (PD) for long period of time. Although the exact mechanisms of peritoneal damage during PD still remain unclear, generation of reactive oxygen species may be responsible for progressive membrane dysfunction. N-acetylcysteine (NAC)is a powerful antioxidant shown to protect peritoneal fibrosis in peritoneal dialysis animal model. In this study the researchers investigated the hypothesis that NAC protect peritoneal membrane damage.

The investigators intend to find out which contrast agent has less kidney toxicity in renal impaired patients undergoing cardiac angiography or percutaneous coronary intervention (PCI).

To evaluation of nailfold microcirculation in patients with chronic renal failure and its intervention therapy

This is a single-center, prospective, open-label, controlled, randomized, cross-over study in 34 prevalent end-stage renal disease patients on chronic hemodialysis treatment with hyperphosphatemia.

This study will compare the clinical outcome of patients with maintenance dialysis room after changing the iron treatment guidelines from original upper limit with ferritin>500ng/ml, or TSAT>20% to Ferritin> 800ng / ml, or TSAT> 50%.

Peritoneal fibrosis is one of the major causes of technical failure in patients on peritoneal dialysis (PD) for long period of time. Although the exact mechanisms of peritoneal damage during PD still remain unclear, generation of Endoplasmic reticulum (ER) stress may be responsible for progressive membrane dysfunction. Ursodeoxycholic acid (URSA) is a powerful inhibitor of ER stress to protect peritoneal fibrosis in peritoneal dialysis in the investigators in-vitro study. In this study the researchers investigated the hypothesis that URSA protect peritoneal membrane damage.

The aim of the study is to identify hepatic enzyme and estrogen-dependent biochemical changes that occur when dialysis patients are treated with dialyzers known to leach BPA (Bisphenol-A) into the blood, such as the commercially available Fresenius F160NR, as compared with the same chemical evaluations in patients being treated with the non BPA containing Nipro Elisio-15H dialyzer. Evaluations of patient's chemistries will be obtained prior to and after 2 months of standard dialysis treatments with each dialyzer.

The aim of this study is to identify families with hereditary chronic tubulointerstitial renal diseases , characterize the phenotype and screen for mutations in known genesis (UMOD, REN, TCF2, NPHP1). Genome wide analysis will be performed in families without mutations identified.

BACKGROUND: Peritonitis remains a significant problem in peritoneal dialysis. It is the leading cause of technique failure, and contributes to mortality. The incidence is highest during the first year of treatment. Non-compliance with the Peritoneal Dialysis (PD) protocol is shown to be an important risk factor for peritonitis. Reinforcement of knowledge and ability to perform PD therefore appears to be a possible way to reduce the incidence of peritonitis. This will be studied in The PEritonitis Prevention Study (PEPS). METHODS: The objective of this randomized, multi-centre investigation,which will include 750 new PD patients who can perform (PD) without assistance, is to evaluate if regular retraining can reduce the incidence of peritonitis, the technique-failure rate, and the hospitalisation days due to peritonitis compared with regular follow-up regimen. Patients in the intervention group will tested by a PD-technique test and a questionnaire at regular intervals after PD-start and after every peritonitis episode with focus on infection prophylaxis. If needed, they will be retrained. The control group will be treated according to the routine of the center. The study is ongoing in Denmark, Norway, Sweden, Finland, Estonia, Latvia, the Netherlands, and the UK. The study will go on for 6 years.
