Filter by:This study is designed to assess the effect of renal impairment on the pharmacokinetics, safety and tolerability of udenafil in subjects with renal impairment compared to healthy subjects.
This study will test the hypothesis that uric acid impairs the function of vessels in patients with kidney disease
Hypothesis: Patients starting peritoneal dialysis with a glucose-based regimen have high sympathetic activity in response to an increase in leptin and insulin. Converting patients from a regimen of only glucose containing dialysate to a regimen with non-glucose-based solution, icodextrin, will reduce the insulin and leptin levels and will reverse dialysis-induced increases in sympathetic activity.
This randomized, single-blind, proof-of-concept study will investigate the protective effects of early treatment with Mircera in participants with chronic kidney disease on renal disease progression. Participants will be randomly assigned to receive 30 microgram (mcg) Mircera as subcutaneous injection once monthly or matching placebo. Depending on change of hemoglobin values, the dose of Mircera can be adjusted to 50 mcg or 75 mcg once monthly. The anticipated time on study treatment is 24 months.
FSGS is an immunologic disorder wherein circulating immune proteins cause damage to the kidneys and progressive injury and scarring. Corticosteroid therapy is occasionally, but not nearly universally, successful in reducing proteinuria, and when patients respond, they have a favorable prognosis. The investigators believe that ACTH therapy (H.P. Acthar Gel) can provide a more rapid, well tolerated reduction in glomerular injury.
Study objective: To investigate the potential anti-proteinuric and renoprotective efficacy of aliskiren in addition to losartan in patients at risk of developing end-stage renal disease (ESRD) Methods: This will be a randomized, double-blind study in which proteinuric, non-diabetic patients with chronic kidney disease (CKD) will be assigned in a 1:1 ratio to one of the following treatment groups for 3 years: - Group A: Losartan (Control arm: conventional treatment)* - Group B: Aliskiren plus Losartan (Intervention arm)* - With optional addition of other anti-hypertensive agents to achieve an optimal target blood pressure of <130/80 mmHg.
Background: - Genetic variation in a particular chromosome is a major contributor to the increased risk for kidney disease that is common in people of African descent, although the specific gene, mutations, and other aspects of the variations remain to be determined. By studying the outcomes of kidney transplant in donors and recipients of African descent, researchers hope to better understand the effects of this genetic variation on the success of kidney transplants. Objectives: - To examine possible connections between genetic variations and kidney transplant outcomes for donors and recipients. Eligibility: - Participants in kidney transplant where both donor and recipient were of black African descent. - Eligible transplants include both living donor and deceased donor. Design: - The study will involve one visit of up to 8 hours. - All participants will provide a detailed personal and family medical history. - All participants will provide blood and urine samples, including a 24-hour urine collection, to test kidney function and collect material for genetic testing. - Donor participants will also have a magnetic resonance imaging (MRI) scan of their remaining kidney.
The purpose of this study is to determine the in-vivo ultrafiltration coefficient for different sizes of xevonta High-Flux dialyzers following FDA guidelines.
Vessel calcification is a recognised cardiovascular morbidity risk factor in patients with chronic kidney disease (CKD). Recent reports indicate a significant role of Matrix Gla-protein (MGP) in decreasing calcification processes. MGP is excretion protein whose mechanism of action is not yet fully explained and which to be activated requires phosphorylation and carboxylation where cofactor is vitamin K. These observations indicate that shortage of vitamin K is a significant risk factor for the development of vessel calcification. Another calcification risk factor in CKD patients are calcium-phosphate disturbances and insufficiency of vitamin D3 which in physiological concentration stimulates MGP transcription. The aim of this study is estimation of influence of vitamin K2 administration over the period of 9 months on vessel calcification in 3.- 5. stage CKD patients. It is a prospective, randomised double-blind study carried out in parallel groups. 60 patients with CKD (GFR 15-60 ml/min) with calcium score >10 (Agatston scoring system) will be qualified for the study. On the basis of randomised selection, patients will be divided into two groups: 30 patients will be given 90 μg vitamin K2 + 10 μg and cholecalciferol 30 patients will be given only 10 μg cholecalciferol. After a 9-month treatment the image diagnostic will be carried out in order to estimate the degree of vessel calcification.
The purpose of this study is to find out how chemicals in the blood of patients with chronic kidney disease affect how medications are removed from the body. The patient will take one dose of three different drugs, one on each week, for a total of three single doses. The investigators want to find out if these three different medications are affected in different ways by the chemicals in the blood of patients with kidney disease.
