Filter by:Iron deficiency, independent of anemia, appears to increase morbidity and mortality as well as impairing health-related quality of life in chronic heart failure (CHF), and these effects are compounded when patients also experience chronic kidney disease (CKD). This study was designed to determine the effects of intravenous iron treatment on morbidity and mortality following an initial 6-month period and a longer period of up to 5 years.
The purpose of this study is to explore the relative importance of the frailty and cardiovascular function as potential exercise-modifiable risk factors for falling in patients receiving haemodialysis.
Chronic Kidney Disease Stage 5 (CKD5) patients receiving maintenance hemodialysis are at an increased risk for developing bloodstream infections. Vancomycin is traditionally used as first-line therapy for treating these infections, but the emergence of less-susceptible bacterial strains necessitates the consideration of alternative antibiotic therapy. Telavancin is a new antibiotic that has broad-spectrum antimicrobial activity against gram-positive bacteria, including vancomycin-intermediate staphylococcus aureus. While dosing recommendations for telavancin are available for patients with normal kidney function, there are no published recommendations for CKD5 patients receiving hemodialysis. A pharmacokinetic study is needed to characterize the pharmacokinetic parameters of telavancin in these patients to determine the extent of drug removal by hemodialysis and to establish dosing recommendations for CKD5 patients on maintenance hemodialysis.
Patients will be randomly assigned to perform the training program in center or home-based . The training program will be conducted in accordance with the recommendations of the American College of Sports Medicine. All training sessions will be preceded by stretching of large muscle groups and heating (5 minutes) and at the end by cool down and stretching (5 minutes). The program will consist of 24 weeks with three sessions per week on alternate days. The aerobic training will be continuous, with an increment of 10 minutes in duration every 4 weeks. The intensity will be prescribed according to ventilatory threshold, characterized by the highest intensity of physical exertion fully maintained by aerobic energy pathways. The intensity control was done by means of the heart rate value obtained at ventilatory threshold. Both groups receive the same intervention. However, a group exercise held in the center on a treadmill with the direct supervision of a physical education teacher. The other group will exercise at home with telephone follow-up weekly and once a month will be held at the training center under the supervision of a physical education teacher. It will also constituted a control group remain without performing any activity during the study period. After 24 weeks patients receive the same advice the team conducting the training at home.
The goal of this study is to find the best techniques to take non-invasive images of the arteriovenous fistula (AVF) in hemodialysis patients.
Patients with severe chronic kidney disease (CKD) are at a great risk for infection due to their immune system being suppressed. Pneumococcal infection is particularly common and often results in death due to inflammation of lung (pneumonia) or the whole body (sepsis). This infection can be prevented using vaccines which help build protective immunity. The currently recommended pneumococcal vaccine (Pneumovax), however, is often inefficient in this group of patients. There is thus an urgent need to improve the existing vaccination policy. The goal of this research is to optimize pneumococcal vaccination of patients with severe CKD. Many patients suffering from CKD have already been vaccinated with Pneumovax. Because this vaccine has low immunogenicity in immunocompromised individuals, they may still develop infection. A new vaccine, Prevnar13, has superior immunogenicity and has been recently approved for immunization. There is, however, no specific policy regarding immunization of adult CKD patients, and it is furthermore unknown whether previous Pneumovax immunization negatively affects immune response to Prevnar13. In order to test whether previous immunization with Pneumovax affects the immune response of severe CKD patients to Prevnar 13, the investigators will immunize two groups of adult stage 4 and 5 CKD patients with one dose of Prevnar 13 and will assess their initial immunological response, its longevity, and vaccine safety. The first group will consist of patients who had been previously immunized with Pneumovax, and the second group will include participants with no history of pneumococcal vaccination. Antibody levels and opsonophagocytic activity (OPA) will be quantified. The longevity of the immune response will be assessed. As a secondary objective, the immune response will be analyzed in the context of demographic and clinical characteristics of the vaccinated participants.
An investigator initiated pilot trial: two arm, double blind, placebo controlled, randomized, parallel group of approximately 750 patients with chronic kidney disease, and who have evidence of overt proteinuria, will be treated with micro-particle curcumin versus placebo over 24 weeks from start of the investigational medication date (approximately 6 months) to test whether curcumin can slow chronic kidney disease progression in patients. Three 30 mg capsules of micro-particle curcumin will be self-administered once daily in the morning to determine the the safety and efficacy of curcumin relative to placebo in reducing albuminuria and slowing the loss of eGFR.
This 12-week double-blind randomized controlled clinical trial aims to investigate the effect of a prebiotic (fructooligosaccharide - FOS) on serum and urinary levels of uremic toxins (p-cresyl sulfate and indoxyl sulfate) of non-dialysis dependent CKD patients, and the impact of such intervention on cardiovascular markers, intestinal permeability, endotoxemia and inflammatory response.
The purpose of this study is to compare the effects of intra-dialysis yoga to an educational program among patients with end-stage renal disease. The investigators hypothesize that yoga as compared to the educational program will significantly improve quality of life.
This study investigates the effect of vitamin D deficiency on drug metabolism and transport in patients with chronic kidney disease (CKD) and in healthy controls. The central hypothesis is that vitamin D concentrations independently affect metabolism and transport function in CKD patients. An over-arching goal of this proposal is to make drug therapies safer and more effective to reduce the significant morbidity and mortality in patients with CKD.
