Active clinical trials for "Kidney Failure, Chronic"

This study aims to investigate the effects of high flux dialyser use and ultra pure dialysate utilization on cardiovascular disease by evaluating cardiovascular morbidity and mortality, progression of carotid artery intima-media thickness and coronary artery calcifications, inflammatory state, lipid levels, nutritional status, and erythropoietin requirement in hemodialysis patient population. It is hypothesized that both interventions in this project may diminish cardiovascular disease in hemodialysis patients.

This pilot study will compare the effects of sodium ferric gluconate complex and iron sucrose on urine concentrations of various chemicals including protein

Patients will be treated with hemodiafiltration (HDF) in postdilution mode, as a control therapy, during 9 weeks. During week 5 the 1st intervention treatment, predilution hemofiltration (HF) or predilution HDF, will be performed as a midweek session. After 4 additional weeks of control therapy the other intervention treatment will be performed. Samples will be taken during week 4, 5 and 9: from inlet blood flow (0, 30, 60, 120 and 240 min), from outlet blood flow and dialysate outflow (30, 60, 120 and 240 min).

The purpose of this study is to identify subjects who are highly sensitized with antibodies. It is difficult for these patients to find suitable kidneys. We propose to treat such patients to decrease the antibodies in such a way, that it may become possible to safely transplant kidneys into them.

The purpose of this study is to determine the effect of recipient vein pretreatment of edifoligide (E2F Decoy), compared to placebo, on graft/recipient vein stenosis in polytetrafluoroethylene (PTFE) vascular access grafts placed for hemodialysis at 6 months after enrollment.

The purpose of this study is to observe the effects of a treatment strategy that incorporates cinacalcet HCl into the management of secondary hyperparathyroidism (HPT) in subjects with ESRD receiving hemodialysis, on bio-intact parathyroid hormone (biPTH), corrected serum calcium, serum phosphorus, and calcium phosphorus product.

The purpose of this study is to demonstrate that the efficacy of cinacalcet when co-administered with the first meal after dialysis is comparable (non-inferior) to the efficacy of cinacalcet when administered during the dialysis study visit.

High blood pressure (hypertension) affects up to 80% of all patients receiving haemodialysis for chronic kidney disease (CKD). High blood pressure is a major cause cardiovascular disease (i.e. strokes, heart attacks and heart failure) and, thereby, cardiovascular deaths in these patients. A significant cause of raised blood pressure in haemodialysis patients is thought to be due to retention of salt in the body. In healthy people the kidneys excrete salt but the kidneys of patients with CKD cannot do this, so salt has to be removed by dialysis. However dialysis cannot remove as much salt as is necessary, and so it accumulates. This fact has been recognized for many years, and health professionals caring for haemodialysis patients often stress the importance of restriction of dietary salt intake. However no research has looked in detail at the mechanisms by which salt raises blood pressure in haemodialysis patients. It is likely that salt directly affects thirst, causing patients to drink more and become overloaded with fluid. In addition, salt may have direct effects on the blood vessel wall, causing failure of adequate blood vessel relaxation. Both of these factors may raise blood pressure. We will conduct a carefully controlled crossover study looking at the effects of a modest reduction in salt intake on BP. During the course of the study, which will last eight weeks, patients will receive both a 5 gram per day and a 10 gram per day salt intake. We will look at how thirst, fluid intake, a number of markers of blood vessel function and blood pressure differ on these two salt intakes.

The purpose of this study is to determine whether a combined bone marrow and kidney transplant will be effective in treating stage II or greater multiple myeloma and associated kidney failure. This study will determine whether transplant rejection and the need for immunosuppressive drugs are decreased with this combined transplant approach.

In children with chronic kidney disease, progression to end-stage renal failure is associated with high patient morbidity and poor quality of life. In adults, inhibition of the renin angiotensin system (RAS) slows down the rate of renal failure progression. This concept is as yet unproven in children, in whom chronic renal failure (CRF) is more commonly due to hypo/dysplastic malformations than to acquired glomerulopathies as typical for adult chronic kidney disease. The current project aims at assessing the genetic and molecular mechanisms and cardiovascular consequences of progressive CRF and to develop a strategy of pharmacological renoprotection in children.
