Active clinical trials for "Kidney Failure, Chronic"

In this study, the investigators will evaluate whether CD4+ TCM producing effector cytokines can be distinguished on the basis of their expression of the IL-7 receptor alpha-chain (CD127). Using CD154 production as a marker of Ag-specific CD4+ T cells, the investigators will also test the hypothesis that the phenotype and function of TCM are influenced by the type of Ag they recognize. TCM specific for two cleared protein Ag, tetanus toxoïd (TT) and hepatitis B surface (HBs), inducing an early stage of CD4+ T cell differentiation will be compared to TCM specific for cytomegalovirus (CMV), a persistent virus inducing an advanced stage of CD4+ T cell differentiation. The primary endpoint is to demonstrate in uremic patients who will begin chronic HD and in patients already chronically hemodialyzed any improvement in CD4+ T cell function ex vivo and in vitro. These analyzes will focus on memory T-cell subsets (i.e. Th17 and Tregs population) using HCO membranes or polyamide dialyzers. The secondary endpoint is a clinical one, namely, to show any improvement in T cell response to HB and TT vaccination (blood antibody titers).

Indoxyl sulfate (IS) is a uremic toxin that accelerates the progression of chronic kidney disease (CKD). AST-120 (Kremezin®; Kureha Corporation, Tokyo, Japan) removes indole, which is the precursor of IS, in the intestine, and reduces the accumulation of IS. This drug has been shown to retard the deterioration of renal function in CKD patients through reducing the levels of IS. IS was reported to promote aortic calcification and stimulate the proliferation of vascular smooth muscle cells (VSMC). IS also inhibits endothelial proliferation and wound repair. With this background, the investigators will performed the study whether AST-120 improve the endothelial dysfunction in CKD patients.

MTR107 effect on blood pressure throught the dialysis procedure and its ability to prevent Intra dialytic Hypotension

This is a prospective, observational, multi-center study with consecutive enrollment. Up to 500 patients will be enrolled. All (consecutive) adult patients in whom one or more components of the Benephit Infusion System are planned to be used at participating sites are eligible for enrollment. The objective of this post-marketing surveillance study is to collect clinical usage patterns of the Benephit Infusion Systems. As a result, AngioDynamics will be able to (1) Better understand and quantify usage patterns including patient characteristics, adjunctive procedures, and infusion agents, (2) Collect user-interface information and overall customer satisfaction, and (3) Monitor post-marketing device performance and safety for ISO quality adherence.

Vascular access complications are the leading cause of morbidity in hemodialysis (HD) patients, and are responsible for a significant percentage of hospitalization, with annual costs approaching one billion dollars in the United States. Thrombosis is the most common cause of vascular access failure, and usually develops from stenotic lesions in the venous outflow tract. It has been reported that far infrared (FIR) therapy can improve access flow and unassisted patency of AV fistula, however, the effect of FIR on cardiac function is unknown. The aims of this study are to evaluate (1) the change of access flow of AV fistula and the effect of AV fistula on echocardiographic parameters and (2) the effect of FIR on access flow of AVF and echocardiographic parameters and the serum levels of endothelial markers in patients with end stage renal disease (ESRD) during the first 6 months after the creation of AV fistula.

Stage 5 chronic kidney disease (CKD), also end stage renal disease(ESRD), usually presents overt clinical symptoms and is a critical stage when patients are encountered with dialysis. The optimal time to initiating dialysis in patients with stage 5 CKD is addressed as the most important dialysis-related question. As indicated by the recently published European Renal Best Practice (ERBP) guideline, early initiation seemed to produce no benefit but greater expenditure and sometimes more harm.Renal replacement therapies (RRT) including dialysis are the most common procedures for patients with end-stage renal disease (ESRD), but conservative management should be an option in patients who still experience the stable period without clinical indications of dialysis.Chinese Medicine (CM) is recognized as an alternative therapy on alleviating uremic symptoms, deferring dialysis initiation, and improving quality of life. Although the effects of CM on kidney disease have been demonstrated in animal experiments, evidence from large clinical trial is insufficient. So we raise the hypothesis that CM therapies including Chinese herbal formula, Chinese patent medicine via oral pattern and/or Colonic administration, will defer the initiation of dialysis in adults with stage 5 CKD.

Aldosterone blockade is useful in preserving residual renal function in patients on PD.The long term efficacy of dual blockade of the RAAS is better than monotherapy.

The purpose of this study is to evaluate the safety,efficacy， pharmacodynamics (PD), and pharmacokinetics (PK) of multiple intravenous doses of EPO-018B in participants with chronic kidney disease (CKD) Who are not on dialysis

The aim of this study is to demonstrate the efficiency of an adapted and "alternate" peritoneal dialysis scheme in terms of sodium extraction and purification compared to an adapted conventional peritoneal dialysis scheme.

Using sweat as the vehicle for removing molecules normally excreted in the urine(dermodialysis) was identified some decades ago.The study will include 66 ESRD patients and 20 CKD stage 5 patients not on dialysis who met inclusion and exclusion criteria. The ESRD patients will be divided into three groups and will be subjected to different modalities of stimulation of sweating like infra-red sauna , physical exercise and hot bath. The study will be conducted over a period of three months. During the first month, patients were dialyzed as usual (control phase).During the next two months ,the participants will be dialysed twice weekly in addition to dermodialysis. S Cr, BUN, serum K and serum phosphorus will be measured weekly immediately before the last dialysis session during the control and intervention phases. The mean of this investigations during each phase will be calculated . The investigators will compare the mean of this investigations during control phase with the mean during the intervention phase to evaluate the effectiveness of dermodialysis as adjuvant therapy for ESRD patients.The patients not on dialysis will subjected to infra-red sauna and hot bath.The investigators also will compare the means of S Cr, BUN, serum K and serum phosphorus during both control and intervention phases like the ESRD patients.
