Filter by:The clinical study aims at providing data on antimicrobial efficiency and a supposed additional preventive effect on catheter-related infections of a catheter with antibacterial surface coating in comparison to standard catheters without coating.
This study aims to show that using a glucose (sugar) concentration of 100 mg/dL in the dialysis fluid for hemodialysis is not inferior to using a concentration of 200 mg/dL with regard to the frequency and magnitude of blood glucose drops. Other parameters that will be compared between the two groups are blood pressure, heart rhythm, weight gain between dialysis treatments, and fatigue after the treatment.
The aim of this multi-center study is to determine the applicability of BMIPP to diagnosing cardiac disease and to predicting the outcome of patients on hemodialysis.
Parenteral iron therapy is now commonly administered to dialysis patients with the majority of patients receiving this therapy as part of the treatment for their anemia. Although intravenous iron has improved clinical response to recombinant erythropoietin, there is a concern that iron therapy may have deleterious effects in Chronic Kidney Disease (CKD) patients. Iron can damage tissues by catalyzing the conversion of hydrogen peroxide to free-radical ions that attack cellular proteins, DNA and membranes as part of oxidative stress. Numerous in vitro studies have shown tissue toxicity from iron and increased infectious potential. Oxidative stress can also lead to activation of the systemic inflammatory response with the release of a number of key cytokines and growth factors. There is now a link between inflammation, oxidative stress and acceleration of vascular disease in both patients with normal as well as reduced renal function. In a study comparing normal versus low hematocrit levels in hemodialysis patients, mortality was higher in the normal hematocrit group. The major difference between the two groups has been attributed to the fact that patients in the normal hematocrit group received significantly more iron than the patients with low hematocrit. There was a 2.4 fold greater mortality rate in patients receiving parenteral iron. The effect of parenteral iron administration on activation of the systemic inflammatory response in hemodialysis patients has not been evaluated. The purpose of this study is to measure a number of key cytokines, inflammatory and oxidative stress markers in hemodialysis patients receiving iron repletion therapy as part of their standard care.
The purpose of the study is to study the ease of use of the Polyflux HD-C4 Small dialyzer under conditions of routine clinical use for hemodialysis
The purpose of this study is to study whether hepatitis C virus (HCV)infected maintenance hemodialysis (MHD)patients have distinct metabolic, inflammatory and adipokine characteristics that can be linked to poor clinical outcome and to examine the hypothesis that HCV infected MHD patients with metabolic syndrome have higher risks for hospitalization, cardiovascular and all-cause mortality.
Chronic hepatitis C virus (HCV) infection is common in dialysis patients. Interferon (IFN)-based treatment for chronic hepatitis C has been the mainstay therapy in immunocompetent patients. Two meta-analyses evaluating the efficacy and safety of conventional IFN alfa monotherapy showed that the sustained virologic response (SVR) rates were 37% and 33%, respectively; and the corresponding dropout rates were 17% and 29.6%, respectively. The efficacy and safety of pegylated IFN alfa-2a and 2b in treating dialysis patients showed conflicting results, with a more favorable outcome of patients treated with pegylated IFN alfa-2a (135-180 μg/week: SVR 33-75%, well tolerated) than those treated with pegylated IFN alfa-2b (0.5-1.0 μg/week: SVR 12.5%, poorly tolerated), Currently, IFN-based therapy to treatment HCV infection should be initiated in dialysis stages, because the use of IFN in RT patients harbors high risks of acute graft rejection,and have low response rates under the concomitant use of immunosuppressive agents. Ribavirin, which has been used in combination with IFN to treat chronic hepatitis C in the general patients and achieve a higher SVR rate than IFN monotherapy, is considered contraindicated in dialysis patients with chronic hepatitis C due to the risk of severe hemolytic anemia. However, some pilot studies evaluating combined conventional IFN alfa plus low dose ribavirin (170-300 mg/day) showed SVR rates of 17%-66% after 24-48 weeks of treatment.In addition, a recent study including 6 patients with combination of pegylated IFN alfa plus low dose ribavirin also showed a SVR rate of 50%. Although dialysis patients have a higher SVR rate to conventional IFN or pegylated IFN monotherapy than patients with normal renal function for HCV therapy. More than half of these patients are relapsers or non-responders to IFN monotherapy. Retreatment of HCV-patients with normal renal function by combined pegylated IFN alfa plus ribavirin who fail to response to IFN monotherapy has achieved a SVR rate of 28%. Based on the long-term favorable outcome in dialysis patients who eradicate HCV, the aim of the study is to evaluate the efficacy and safety of retreatment by pegylated IFN alfa-2a plus low dose ribavirin in dialysis patients who fail to achieve HCV eradication by conventional or pegylated IFN alfa.
Decreased body fat mass, possibly mediated through the effects of elevated serum adiponectin levels, may be associated with requirements for higher recombinant human erythropoietin doses and a subsequent worse prognosis in patients beginning hemodialysis.
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.
The aim of the study was to determine the effects of a 3-week fish oil oral supplementation on the metabolic fate and thermogenic effect of an oral glucose load in hemodialysis patients.
