Active clinical trials for "Kidney Failure, Chronic"

Background Prevention of contrast media (CM) induced nephropathy (CIN) by pharmacological prophylaxis (e.g. N-acetylcysteine; NAC) is controversially discussed. So far, in all interventional studies assessment of kidney function was based on measurements of serum creatinine although this surrogate biomarker has several limitations. We investigated the antioxidants NAC and zinc (Zn) for the prevention of CIN by monitoring concomitantly serum levels of creatinine and cystatin C.

To establish the efficacy and Safety of rHu-EPO-alpha in patients with anemia of Chronic Renal Failure.

This study aims to compare high-efficiency post-dilution on-line hemodiafiltration and high-flux hemodialysis regarding mortality, hospitalization rate, several clinical and laboratory parameters, and required medications. The investigators hypothesize that high-efficiency post-dilution on-line hemodiafiltration may provide better outcome, less morbidity, higher quality of life, and lesser requirement of medications.

Chronic hemodialysis (CHD) patients display multiple metabolic abnormalities related to advanced uremia. Despite vigorous attempts to prevent these abnormalities and their consequences, most CHD patients suffer from a unique form of nutritional derangement, which can be termed as "uremic wasting". Several studies have demonstrated that the presence of uremic wasting, especially the degree of loss of muscle mass, sharply increases mortality and hospitalization rate in CHD patients. Several factors have been thought to be associated with uremic wasting, including hormonal derangement, anorexia, physical inactivity, and concurrent illnesses. Chronic inflammation, also highly prevalent in these patients, causes muscle catabolism in animal models and certain clinical conditions. Epidemiological studies show an association between chronic inflammation and uremic wasting in hemodialysis patients indicating a possible causal relationship. The cause for the activated inflammatory state in CHD patients is believed to be multi-factorial. Nevertheless, it is certainly important for the host to limit its biological activity by eliciting a stronger anti-inflammatory response, for example through the production of naturally occurring receptor antagonist. Interleukin 1 beta, one of the major pro-inflammatory cytokines has been shown to be associated with protein catabolism in several chronic disease states, including advanced uremia. A balance between interleukin 1 beta (agonist) and its naturally occurring receptor antagonist IL-1ra may play a pivotal role in controlling the inflammatory response and its consequences in this population. The overall goal of this particular grant application is to examine the short-term effects of the administration of the recombinant form of IL-1ra on 1) chronic inflammatory state and 2) protein homeostasis in chronically inflamed CHD patients. We have updated our protocol to perform an interim analysis. The interim analysis will be performed after half of the planned study sample has been enrolled (14 subjects; 7 in each arm). The interim analysis has been approved by the Data Safety Monitoring Board.

The purposes of the study are to determine whether oxidative stress causes the muscle of dialysis patients to tire more quickly than muscle of people without kidney disease and to determine whether treatment with N-acetylcysteine, an antioxidant, can improve muscle endurance.

This is a 12-month, phase II, prospective, open label study, to evaluate the effect of mycophenolate mofetil (MMF) among patients on the kidney transplant list with high Panel of Reactive Antibody (PRA) levels. On average, increasing the PRA from 0 to 50% specifically in the Washington Organ Procurement Organization (OPO) increases the waiting time from 3 to 6 years. Spontaneous decreases in the PRA rarely occur and is associated with a decreased chance for transplantation and a decreased rate of survival.

The purposes are to measure the effect of dialysis with glucose on blood pressure, pulse rate, plasma concentration of glucose, plasma concentrations of glucagon, growth hormone, renin, angiotensin II, endothelin and body temperature, and to analysis the relationship between changes in blood pressure on the one hand and changes in vasoactive hormones on the other

This study is designed to study and compare the efficacy and cost-effectiveness of individualized phosphate-lowering therapy in comparison with regular guideline-recommended therapy.

The objective of this study is to assess the performance and safety of the Optiflow Anastomotic Connector (Optiflow) when used to facilitate the creation of autogenous arteriovenous fistula (AVF) anastomoses.

To investigate the efficacy, pharmacokinetics, pharmacodynamics, and safety of OPC-41061 in patients with chronic renal failure who are undergoing peritoneal dialysis, using daily urine volume, body weight, and edematous conditions as parameters and conducting dose escalation every 2 days until reaching the dose that achieves urine volume increase and then performing 5-day repeated administration at the fixed dose, the final dose used in the dose escalation period.
