Active clinical trials for "Kidney Failure, Chronic"

The purpose of this study is to describe alterations of serum ferritin, transferrin saturation, soluble transferrin receptor, % hypochromic erythrocytes, % reticulocytes, reticulocyte hemoglobin content after iron loading in hemodialysis patients.

Chronic kidney disease (CKD) is linked to elevated mortality rate, and cardiovascular disease is the main cause related to this outcome. The cardiovascular mortality among patients on conventional hemodialysis (CHD) is high, achieving up to 30 times more risk of death when comparing to individuals of same age on general population. Congestive heart failure can develop in 25% to 50% of patients, leading to a worse prognosis. CKD patients present anatomic and functional abnormalities on peripheral bed vases and also cardiovascular abnormalities that can cause myocardial ischemia. This last usually is transitory and lead to left ventricular dysfunction that can persist even after the end of dialysis session despite normal coronary perfusion. The prolonged dysfunction is called myocardial stunning (MS). Patients on CHD are subject to hemodynamic instability, myocardial ischemia and development of regional abnormalities of myocardial wall (ARPM´s). MS induced by intradialytic ischemia is a complication that can be minimized by applying techniques associated to more stability during the CHD, as cool dialysate or increasing the length of the therapy. The goal of the present study is to evaluate the behavior of cardiovascular system (trough hemodynamic performance during CHD, accessing MS by echocardiography technique, and biomarkers associated to MS). Finally, the investigators aimed to investigate the role of two different dialysate calcium concentration (2,5 and 3,5 mEq/l) in the genesis of MS during CHD. The elucidation of pathogenesis of MS during CHD might help us modified hemodialysis technique in order to prevent MS, and reduce the high cardiovascular mortality among CKD patients.

The purpose of this study is to evaluate the effects of pharmaceutical care interventions in the ambulatory hemodialysis patients over a one-year period. Cost containment occurs through pharmaceutical care interventions designed to identify and ameliorate drug-related problems (DRPs), improve the cost-effectiveness of therapeutic regimens and prevent hospitalizations.

The purpose of this study is to determine the effects of different amounts of phosphorus in the diet on hormones that control phosphorus and bone health both in people who are healthy and in ones who have moderate kidney disease.

The study aims to determine the pharmacokinetic (PK) profile of a single oromucosal dose of Sativex® (i.e. how the body absorbs, distributes, metabolises and excretes the drug) when subjects have severe renal impairment or end stage renal disease (ESRD), compared with subjects who have normal renal function. The primary clinical hypothesis is that there will be an effect from severe renal impairment on the PK of Sativex® when administered as a single oromucosal dose. The study additionally aims to evaluate the safety and tolerability of the same single oromucosal dose of Sativex® in subjects with severe renal impairment or ESRD.

The primary purpose of this pilot study is to assess the pharmacokinetic profile of low-dose bevacizumab and its effectiveness in reducing plasma free VEGF-A levels safely in hemodialysis patients. This information will be used to plan a phase 1 clinical trial evaluating bevacizumab's role in hemodialysis vascular access failure.

Phase IV post-marketing study to evaluate the effect of Extraneal on the HOMA index in non-diabetic CAPD patients over the long-dwell exchange. The purpose of the study is to investigate if the use of Extraneal (which is a mixture of high weight glucose polymers), instead of glucose-based solutions such as Dianeal is going to lower the HOMA index in non-diabetic CAPD patients.

This study was to explore the impacts of participating in "ACP board game for life" on death preparation, death anxiety, end-of-life care preferences, and intervention perception in stage 4-5 CKD patients with advanced chronic kidney diseases in a medical center.

The goal of this observational study is to assess validity and reliability of Persian Version of Low Physical Activity Questionnaire. The main questions it mains to answer are: What is the level of physical activity in hemodialysis patients? Is Persian Version of Low Physical Activity Questionnaire, Valid to assess physical activity levels of dialysis patients? Is Persian Version of Low Physical Activity Questionnaire, reliable? Participants will answer 3 questionnaires and will do some functional tests.

Intravenous iron therapy is common and effective, with few side effects. Two formulations are used, venofer or iron sucrose and ferrlecit, or ferric gluconate. The association between intravenous iron use and decrease in serum phosphorus and vitamin D levels, with increased fractional excretion of phosphorus, has been observed with older iron preparations, such as saccharated ferric oxide. However, hypophosphatemia and osteomalacia have been reported with iron carboxymaltose, a newer iron formulation. There is no information in the literature about phosphorus and vitamin D levels after treatment with venofer or ferrlecit. We intend to check phosphorus and vitamin D serum levels in our patients prior to and after treatment with these iron formulations.
