Filter by:The purpose of this study is to learn more about why most patients with early stages of kidney disease have high blood pressure. We know the body produces natural substances that cause blood vessels to open wider to carry more blood when needed. An example is during exercise. Other natural substances cause blood vessels to get smaller and slow down blood flow when needed. An example is when people are cold. The balance between these substances is important. People with kidney disease and high blood pressure do not have the normal balance of these substances. This study will include 3 groups of people, people with normal blood pressure, people with high blood pressure and people with kidney disease. - Subjects will have a screening physical examination, including an ECG and laboratory tests - Subjects with high blood pressure may not take their regular blood pressure medication for 3 weeks prior to the inpatient GCRC study - Subjects will be given intra-arterial medications that will cause changes in the blood vessels during the in-patient study. The study will then compare the responses of the three groups. A GFR test will be done to confirm the renal function of the group with chronic kidney disease. These studies will provide insight into the mechanisms of the pathogenesis of enhanced α1 vasoreactivity in subjects with progressive renal disease. This will lay the groundwork for new strategies in the treatment and prevention of vascular disease among the rapidly growing group of individuals with CKD.
The purpose of this study is to assess disability in anemic patients over the age of 65 who have kidney disease and are receiving weekly PROCRIT® (Epoetin Alfa, a glycoprotein that stimulates red blood cell production).
The primary goal of the trial was to evaluate whether the optimal antiproteinuric doses of benazepril (an ACE inhibitor) or losartan (an ARB), as compared with their conventional doses, can safely improve the long-term renal outcome in nondiabetic patients with proteinuria and chronic renal insufficiency. The second aim was to compare the long-term renal protection between benazepril and losartan at similar clinical setting.
The purpose of the study is to assess the effect of an early and complete correction of anemia after treatment with epoetin alfa on the rate of progression of chronic renal failure (which involves improper functioning of the kidneys). It also assesses the effect of hemoglobin normalization (correction of anemia) on the need for renal (kidney) replacement therapy, quality of life, blood pressure control, hospital admissions, mortality, cardiovascular events, nutritional status and safety.
The purpose of this study is to further determine whether benazepril, could safely slow the progression of renal dysfunction in non-diabetic patients with advanced renal insufficiency.
Circulating concentrations of cytokines, such as leptin, tumor necrosis factor-alpha and interleukins 1 and 6 are increased in patients with chronic kidney disease (CKD). In light of the increasing recognition that growth hormone receptor signaling involves cytokine pathway activation, the investigators hypothesize that maladaptation of cytokine regulation in chronic kidney disease may underlie growth failure. Secondly, they hypothesize that administration of recombinant human growth hormone (rhGH) will result in growth rate stimulation in pre-pubertal children with growth impairment due to chronic kidney disease by down regulation of the cytokine pathways. This is a non-randomized open-label study to evaluate the effect of recombinant human growth hormone on biochemical/metabolic and immunologic parameters in relation to body composition pre- and post-recombinant human growth hormone therapy of pre-pubertal growth hormone naive children. The efficacy of recombinant human growth hormone to improve growth velocity in pre-pubertal children with growth failure is a secondary objective. Fifteen children are to be studied over a six month period. Each patient will serve as his/her own control. Six months of growth data prior to study is required.
Left ventricular hypertrophy (LVH) predicts mortality at start of dialysis. Prevention of of LVH is important. It is not known whether secondary hyperparathyroidism might induce LVH. In the present study patients are randomised to 1.25 dihydroxycholecalciferol or no treatment to study the effect on LVH.
The purpose of this study is to look at subject incidence of adverse events.
To evaluate the safety profile of single intravenous (IV) dose levels of peginesatide in participants with chronic kidney disease(CKD) not on dialysis.
To evaluate the survival benefit associated with Zemplar therapy as compared to Calcijex for the treatment of secondary hyperparathyroidism in subjects with Stage V chronic kidney disease on hemodialysis as measured by time to death.
