Active clinical trials for "Kidney Failure, Chronic"

The primary goals of this investigation are to provide guidance on how to dose Argatroban in patients undergoing hemodialysis and to assess the safety and tolerability of Argatroban in hemodialysis patients. The secondary goal of the study will be to assess the adequacy of anticoagulation during hemodialysis.

This study will examine the effects of long-term adherence to a low protein diet (LPD) of 0.6 g/kg-1/d-1 with and without progressive resistance exercise training in patients with impaired renal function on body composition, renal function (glomerular filtration rate), nitrogen balance, muscle strength and size, and functional capacity. The hypothesis is that adherence to a LPD will result in a reduction in skeletal muscle mass and reduced strength and functional capacity while those patients who adhere to the LPD and exercise will demonstrate a similar preservation of renal function but will have greater fat free mass, muscle mass and strength. The intervention trial will last 18 months in which patients with moderate renal failure will be randomly assigned to one of 4 interventions: standard care, standard care + exercise, LPD, and LPD with exercise. In this way the independent and combined effects of diet and exercise on the progression of renal disease and body composition will be monitored. This study will have important implications for the treatment of patients with chronic renal failure. New strategies of combining exercise with recommendations of a low protein diet may slow the progression of renal disease and improve strength and functional capacity in these at-risk patients.

OBJECTIVES: I. Evaluate the separate and combined skeletal effects of recombinant human growth hormone (GH) and calcitriol in patients with adynamic renal osteodystrophy. II. Assess whether calcium-regulated changes in parathyroid hormone secretion predict changes in bone formation. III. Characterize the response to GH in cancellous bone and in growth plate cartilage in patients with secondary hyperparathyroidism during calcitriol therapy.

Low physical activity is associated with in hemodialysis and hemodiafiltration (HDF) patients. Previous studies showed the benefits of intradialytic exercise for improvement of physical fitness and hemodialysis adequacy. However, the effect of intradialytic exercise on physical activity has not been explored. This current open-labelled randomized controlled trial is conducted in HDF patients to determine the effect of intradialytic exercise program for 6 months on daily physical activity measured by tri-axial accelerometer (wearable device).

The overall aim of the study is to prospectively investigate the impact of two maintenance calcineurin inhibitor immunosuppressive regimens: once-daily extended release tacrolimus and twice-daily tacrolimus on subpopulations of T and B cells and alloreactive T cells as well as on renal allograft function.

The main purpose is to establish the equivalence of Triferic iron administered via dialysate into the arterial blood line and into the venous blood line

In China, the estimated prevalence of patients with ESRD receiving peritoneal dialysis (PD) or maintenance hemodialysis (HD) increased from 51.7 per million population (pmp) at the end of 2007 to 79.1 pmp at the end of 2008. There is a growing body of evidence that large uremic solutes play a significant role in clinical complications in dialysis patients. Since high-flux membranes show low permeability for large uremic solutes, extracorporeal blood purification treatments using these membranes have failed to significantly eliminate and reduce plasma levels of these molecules. To remove large sized uremic solutes by dialysis the membrane needs to have adequate permeability properties (pore size, porosity) for these solutes. The Theranova 400 contains a dialysis membrane that has a sharper sieving profile and a higher cutoff than that in conventional high-flux dialysis membranes. The primary objective of this study is to demonstrate non-inferiority of the Theranova Dialyzer compared to the FX80 with clinical endpoints.

Endexo™ is an additive that is blended into the fiber solution during manufacturing of the hemodialyzer hollow fibers. The intended purpose of the additive is to increase blood compatibility in the finished dialyzer, which is referred to as the "dialyzer with Endexo."

Insomnia is a common and distressing symptom for patients on hemodialysis (HD), and there is evidence for a much larger impact on the health of patients. Chronic insomnia is disrupted sleep that occurs at least three nights per week and lasts at least three months. The SLEEP-HD study is a randomized open-label clinical trial to compare two types of treatment for insomnia in participants who have end-stage renal disease on HD, and who have been diagnosed with chronic insomnia. The two types of treatment involved in the study are Cognitive Behavioral Therapy for Insomnia (CBT-I) or treatment with a drug (trazodone vs placebo). 126 participants will be enrolled who are undergoing HD in two study locations (Seattle, Washington and Albuquerque, New Mexico).

End-stage renal disease patients undergoing hemodialysis can present alteration in flow, concentrations and composition of saliva affecting oral health. This randomized placebo-controlled trial aims to evaluate the effectiveness of photobiomodulation therapy (PBM) in salivary parameters in chronic renal failure (CRF) patients undergoing hemodialysis. Forty-four patients with CRF on hemodialysis self-responded two questionnaires for oral health and salivary gland function perception. Thereafter, patients were clinically evaluated for the diagnosis of hypofunction of salivary glands and were randomly allocated into two groups: PBM group (n = 21), which received three irradiations of laser at ʎ = 808 nm, 100 mW, 142 J/cm2 and 4 J per point; and a placebo group (n = 17) that consisted of laser protocol with the device switched off. Patients were first submitted to sialometry and after to PBM or placebo intervention at baseline, 7 and 14 days. Non-stimulated and stimulated saliva were collected for salivary volume investigation and biochemical analysis of total protein, calcium and urea concentrations.
