Active clinical trials for "Kidney Diseases"

Hypothesis: The supplementation of Ergocalciferol (Vitamin D2) to those with Vitamin D deficiency in the Chronic Kidney Disease population requiring recombinant human erythropoietin for the treatment of anemia related to kidney disease will reduce the dose of erythropoietin required to maintain a nonanemic state.

Triptolide has been approve effective in animal model.

The hypothesis of the current proposal is that chronic pioglitazone therapy will result in improved endothelial function, decreased inflammation, and preservation of renal function in patients with CKD but without diabetes.

This is a multi-center clinical study in subjects requiring arteriovenous grafts in the upper extremity for hemodialysis access. All subjects will provide informed consent before undergoing any study procedures. The study will consist of multiple subject visits and telephone contacts during the 52 week study period. During the study period subjects must also maintain an appropriate hemodialysis schedule. IDE Number: G060250

An important subgroup of protein-bound toxins are generated as a result of protein fermentation in the colon. P-cresol is a fermentation metabolite of tyrosine. In renal failure, the colonic generation rate of p-cresol is markedly elevated. After absorption, the majority of p-cresol is conjugated to form p-cresyl sulphate. There is clear evidence, both in vitro and in vivo, that accumulation of conjugated fermentation metabolites is correlated with clinical important endpoints. Free p-cresol is an independent predictor for mortality in hemodialysis patients. Moreover, in renal failure patients, neither hemodialysis nor peritoneal dialysis is capable of normalising the clearly elevated serum concentrations of p-cresyl sulphate. Removal is at least partially diminished by the important protein binding of p-cresol. Besides adaptation of renal replacement therapies to improve removal of protein bound solutes, another approach is to lower the generation of uremic toxins. The mechanisms underlying colonic carbohydrate and protein fermentation, responsible for the generation of p-cresol, are only partially understood. On the one hand, the ratio of fermentable carbohydrates to proteins has been shown to be an important determinant of protein fermentation. On the other hand, changes in the colonic bacterial flora influence the generation of p-cresol in dogs and in healthy human individuals. The effect of antibiotic therapy on bacterial protein fermentation and thus on the generation of p-cresol is not known. A reanalysis of data abstracted from a recent longitudinal study in peritoneal dialysis (PD) patients suggests that antibiotic therapy may lower p-cresol levels substantially. The current study aims at confirming these data in a prospective manner.

The primary objectives of this study are the following: To test if the proportion of participants achieving a hemoglobin value greater than or equal to 10.0 g/dL at any time point after the first dose during the study is greater than 0.8 when administered de novo darbepoetin alfa once a week (QW) for treatment of anemia in pediatric patients with chronic kidney disease receiving and not receiving dialysis, and To test if the proportion of participants achieving a hemoglobin value greater than or equal to 10.0 g/dL at any time point after the first dose during the study is greater than 0.8 when administered de novo darbepoetin alfa every 2 weeks (Q2W) for treatment of anemia in pediatric patients with chronic kidney disease receiving and not receiving dialysis.

The purpose of this study is to compare alfacalcidol and paricalcitol in the treatment of secondary hyperparathyroidism in hemodialysis patients.

The purpose of this study was to evaluate the long term safety and tolerability of peginesatide for the maintenance of hemoglobin in participants with chronic kidney disease (CKD) who had received at least 24 weeks of peginesatide treatment in an earlier study.

30 non-diabetic, non-obese patients with stage 4 chronic kidney disease will be asked to participate in this metabolic study. The primary aim of this study is to determine the effect of rosiglitazone on insulin resistance in non-obese patients with non-diabetic stage 4 CKD. Secondary end points are the effects on inflammation (hsCRP), lipid profile, bone density and body composition.

Malnutrition and altered protein catabolism are serious problems in renal failure and hemodialysis (HD) patients. The purpose of this study is to characterize the safety of GHRP-1/AG in subjects with ESRD on HD; to characterize the pharmacodynamics (PD) of GHRP-1/AG in subjects with ESRD on HD by following GH and IGF-1; to describe the relationship between GHRP-1 PD and plasma concentrations of GHRP-1 and des-Ala-GHRP-1; and to evaluate the preliminary efficacy of GHRP-1/AG on nutritional status of subjects with ESRD on HD using subjective global assessment of malnutrition inflammation scores (MIS) and changes in caloric intake.
