Active clinical trials for "Renal Insufficiency, Chronic"

The study is about possible protective effects of paricalcitol (Zemplar) upon inflammation, blood pressure and kidney function. Kidney Inflammation occurs when white blood cells become abnormally stimulated and accumulate in the kidney and cause damage to the kidney. The purpose of this study is to determine if paricalcitol helps improve kidney injury, blood pressure control and kidney function in patients with chronic kidney disease. The study will last about 7 weeks and involves about 8 visits to the medical center.

The purpose of this study is to determine the effect of a colecalciferol substitution in dialysis patients on bone metabolism and immune system

To compare the efficacy of Fosrenol (Lanthanum carbonate) and sevelamer hydrochloride in the reduction of serum phosphorus levels from baseline.

This 2 arm study will compare the effect on hemoglobin response of Mircera and epoetin beta, in patients with chronic renal anemia who are on dialysis. Eligible patients will be randomized to receive either Mircera (0.4 micrograms/kg i.v. every 2 weeks) or epoetin beta (3 times weekly, according to approved labelling). The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

An important group of protein-bound uremic retention solutes originate from protein fermentation in the colon. P-cresol is a putrefaction metabolite of tyrosine. Indole is generated by fermentation of tryptophan. After absorption, the majority of p-cresol and indole are further metabolised and conjugated to form p-cresylsulphate and indoxyl sulphate. There is clear evidence, both in vitro and in vivo, that accumulation of these conjugated fermentation metabolites in kidney disease is correlated with clinical (cardiovascular) endpoints. Bacterial protein fermentation can be influenced by altering the colonic microenvironment, influencing the ratio of available carbohydrates to nitrogen, by shortening the colonic transit time or a combination of these. From a theoretical point of view, functional foods, i.e. pro-, pre- and synbiotics, fulfil these criteria. Prebiotics have been defined as non-digestible food ingredients that beneficially affect the host by selectively stimulating growth, and/or activity, of one or a restricted number of bacteria in the colon. Dietary fibre may suppress the generation of bacterial protein fermentation either by altering the colonic microenvironment or by shortening the colonic transit time. Animal and clinical studies evaluating the effect of dietary fibre supplements on the generation of bacterial fermentation metabolites have provided conflicting results. These discrepancies may be related to specific properties of the dietary fibre investigated. Dietary fibre may impair protein assimilation and the fermentability may vary to a substantial extent. Inulin and oligofructose have attracted much attention recently as nonabsorbable carbohydrates with prebiotic properties. When inulin and oligofructose were added to a controlled diet, significant increases were noted in colonic bifidobacterial populations, and it has been proposed that these changes promote both colonic and systemic health through modification of the intestinal microflora. Inulin and oligofructose are rapidly and completely fermented by the colonic microflora with the production of acetate and other short-chain fatty acids. In healthy individuals, supplementation with a mixture of inulin and oligofructose was shown to lower p-cresol generation. Although data in healthy volunteers are promising, no data are available in hemodialysis patients.

This study will determine the titration regimen for SBR759 compared to sevelamer HCl in lowering serum phosphate levels in Asian Chronic Kidney Disease patients on hemodialysis

The main purpose of the study is find whether the addition of statin (Atorvastatin) to dual renin-angiotensin-aldosterone system blockade involving angiotensin converting enzyme inhibitor and AT-1 angiotensin II receptor blocker leads to the reduction of proteinuria, main prognostic marker of chronic kidney disease progression.

The main purpose of this study is to obtain preliminary information on the efficacy, safety and cost of two regimens, Rapamycin / MMF / steroid therapy and Cyclosporine A Neoral / MMF / steroid therapy, used in the prevention of acute rejection following renal transplantation.

The purpose of this study is to evaluate the efficacy and safety of a 7.5% Icodextrin peritoneal dialysis solution for once-daily long dwell exchange in patients undergoing Continuous Ambulatory Peritoneal Dialysis (CAPD) in Chinese uremic patients.Patients were divided into Dianeal group or Extraneal group for long dwell time. Net ultrafiltration, small solute clearance and relationship between different transport group were used to evaluate efficacy of Icodextrin. Physical examination, vital signs and laboratory tests were used to evaluate safety of Icodextrin.

A randomized, cross-over, open-label study will be conducted to evaluate the equivalency, safety and tolerability of sevelamer once per day dosing, given with the largest meal, compared with standard three times per day dosing, in hemodialysis patients previously using sevelamer. Following a two week Run-In period, a total of 24 patients will be randomized to one of the following treatment sequences: sevelamer dosed once a day with the largest meal followed by standard three times per day dosing with meals sevelamer dosed three times per day with meals followed by once a day dosing with the largest meal. Patients will maintain a fixed daily dose throughout both treatment periods based on the most recently prescribed sevelamer dose prior to screening.
