Active clinical trials for "Kidney Diseases"

Peritoneal Dialysis (PD) is a technique for treating kidney failure where fluid is instilled into the body's peritoneal cavity. Fluid and solutes travel across the peritoneal membrane, and the function of this membrane is critical to successful PD. Studies have shown that certain demographic and clinical variables explain a very small part of the variability in baseline function. This study will further explore the common genetic variants that determine the baseline peritoneal membrane function in patients starting treatment with PD and change in function upon treatment . This study will incorporate data from subjects' first ever peritoneal equilibrium test (PET), changes in the transfer of water across the peritoneal membrane over time, demographic information, and results from laboratory analysis of DNA, blood, and dialysate. The investigators hope that this study will provide information on the biological pathways that account for variability in the peritoneal membrane. This could ultimately lead to the development of biomarkers to identifying individuals at risk for decline in peritoneal membrane function over time and/or be used to identify novel therapeutic targets to preserve or enhance membrane function. Identifying the biological pathways will also increase the understanding of vascular biology, angiogenesis, and fibrosis that could be applied to other tissues and other diseases.

Myocardial fibrosis is the fundamental substrate for the development of heart failure. Cardiovascular magnetic resonance (CMR) allows non-invasive assessment of myocardial fibrosis based on late gadolinium enhancement (LGE) and T1 mapping. Patients: Prospective longitudinal observational multicenter study of consecutive patients with suspected or known non-ischemic cardiomyopathy. Imaging: Non-invasive measures of myocardial fibrosis: native T1, extracellular volume fraction (ECV) and LGE. Primary endpoints: all cause and cardiovascular mortality. Secondary endpoints: arrhythmic composite and HF composite endpoints.

Oxidative stress is involved in the pathophysiology of diabetic nephropathy. The superoxide-generating nicotinamide adenine dinucleotide phosphate-oxidase 2 (NOX2, encoded by the CYBB gene) and the antioxidant enzyme glutathione peroxidase 4 (GPX4) play opposing roles in the balance of cellular redox status. In the present study, we investigated associations of single nucleotide polymorphisms (SNPs) in the regulatory regions of CYBB and GPX4 with kidney disease in patients with type 1 diabetes.

This prospective observational study is designed to find out what treatment options new patients with chronic kidney disease learn about from their renal unit. Aims: To determine the proportion of new CKD patients who receive information about treatment options prior to commencing dialysis, pre-emptive transplantation or conservative management. To determine the timing (i.e. patient's stage of disease) when information is given. To find out whether patients have a friend or family member with them when information is given. Research Design and methods: This study is an assessment of CKD education practices. Nephrologists and pre-dialysis coordinators from each renal unit will complete questionnaires about information that was given to each new dialysis, pre-emptive transplant or conservatively managed patient that started treatment during a 3 month period. Study hypothesis: Approximately one third of CKD patients will receive information after starting treatment. There will be a positive association between in-centre haemodialysis and later referral, non-English speaking background, and advancing age. Significance: The results from this national audit will provide Australian nephrologists and renal nurses with evidence about CKD education practices and compliance with clinical practice guidelines. The results may highlight opportunities for improvement in practice.

This is a prospective 5-year study to compare the change in total kidney volume (TKV) before and after tolvaptan therapy, as the primary endpoint, in patients with ADPKD.

Increasing sodium intake raises blood pressure. And high salt intake could hinder the management of chronic disease. Much previous research has confirmed that dietary habits are affected by economic status. So we compared sodium intake with economic status. We investigated the prevalence, extent and management, and the relevance of sodium intake with income level.

The EPOCH-RRT study seeks to fill knowledge gaps by gaining more understanding of chronic kidney disease (CKD) patients' priorities; assessing the comparative benefits of hemodialysis (HD) versus peritoneal dialysis (PD), with respect to these priorities; and providing tailored information to assist patients with identifying the best dialysis modality fit for their own unique circumstances and perspectives. The outcomes most relevant to patients ("patient-centered") extend beyond those traditionally assessed in clinical research, with the relative importance varying across patient groups. A tailored decision aid based on these findings can improve patient decision-making processes regarding choice of dialysis modality.

The purpose of this study is to determine whether hydration with intravenous saline matched with urine output, using the device RenalGuard is superior to standard hydration with saline to prevent contrast-induced nephropathy.

Chronic kidney disease (CKD) and end-stage renal disease are highly prevalent in Taiwan. Cardiovascular disease (CVD) is the most common cause of death in children with CKD. Nitric oxide (NO) deficiency links CKD and CVD. Asymmetric dimethylarginine (ADMA), a NO synthase inhibitor, its level is increased in kidney disease and cardiovascular disease and serves as a methylation biomarker. In addition to ADMA, uremic environment, hyperhomocysteinemia (Hcy) and oxidative stress may affect DNA methylation. S-adenosylmethionine (SAM) is an important human methyl donor. S-adenosylhomocysteine (SAH) is demethylated product. Methylenetetrahydrofolate reductase (MTHFR), a folate metabolism enzyme can regulate methylation pathway. The investigators intend to examine whether ADMA, SAM/SAH ratio, Hcy, and MTHFR gene methylation can serve as biosignature to predict CVD in children with CKD children.

Patients with end-stage kidney disease (ESKD) must manage not only the demands of dialysis and comorbid conditions but also associated symptoms and acute life-threatening events that contribute to functional limitations and increased risk of mortality. Yet little is known about the trajectories of quality of life dimensions in patients with ESKD when they experience acute life-threatening episodes, to guide palliative care for this population. In this prospective, descriptive study, we will identify trajectories of symptoms, physical functioning, psychosocial needs, and emotional and spiritual well-being in 200 patients with ESKD who are at a high risk of experiencing acute life-threatening events and mortality within 12 months.
