Active clinical trials for "Kidney Diseases"

Dialysis access, which is the connection that allows blood to flow in and out of the body during dialysis sessions, is important to remove wastes and excess fluid for patients with end stage renal disease (ESRD). One method used to access the vein and artery for dialysis is called a brachiocephalic fistula. Patients are being asked to participate in this study because they have endstage renal disease, and their doctor has recommended that they will have brachiocephalic fistula placed for their dialysis access. A common problem seen in patients with a brachiocephalic fistula (BCF) is cephalic arch stenosis (CAS). CAS is a narrowing in the central vein (located in the upper chest). CAS causes problems with the opening of the veins and arteries needed for dialysis. Once someone suffers CAS they may need several radiology procedures as well as surgery to help correct the problem. The BCF may fail once CAS develops. The purpose of the research study is to gather information about the BCF and what is happening inside the vein. The researchers hope to find out what may be the cause of CAS.

It is estimated that in the United States there are approximately 8 million individuals with moderate to severe chronic kidney disease (CKD), not on dialysis. Volume expansion plays an important role in the pathogenesis of hypertension in patients with CKD. For this pilot study, the investigators hypothesize that administration of chlorthalidone among patients with moderate to severe CKD will improve blood pressure (BP).

The purpose of this study is to assess the pharmakokinetic properties of higher doses (500 mg and 1000 mg) of Monofer® in patients suffering from Non-dialysis Dependent Chronic Kidney Disease.

The purpose of this study was to determine the dose ranges of peginesatide administered intravenously or subcutaneously that maintained hemoglobin in participants on dialysis whose hemoglobin values were stable on epoetin (alfa or beta).

This 2 arm study will compare the level of anemia, and the decline in renal function, between patients receiving NeoRecormon, and those not receiving it. Patients with chronic kidney disease, stage 2-4, and not receiving dialysis, will be randomized 2:1 to a group receiving NeoRecormon (at a dose determined by the investigator to achieve and maintain an Hb level of 120-135 g/L), or to a control group not receiving NeoRecormon. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

Cardiovascular related disease is the main cause of death in patients with kidney disease, and "oxidative stress" is thought to be a major contributor by promoting thickening of the heart muscle and stiffening of the arteries. Allopurinol, a drug used safely in the treatment of gout for many years, has been found to dramatically reduce "oxidative stress". It is therefore hoped that it also reduce the thickened heart muscle and stiffened arteries. If it did, it is likely to reduce the appallingly high cardiac death rate in this group of kidney disease patients.

This 2 arm study will compare the hemoglobin maintenance with once monthly methoxy polyethylene glycol-epoetin beta (Mircera) administration versus epoetin beta or darbepoetin alfa in participants with chronic kidney disease on hemodialysis. Participants will be randomized to receive either monthly intravenous (IV) or subcutaneous (SC) methoxy polyethylene glycol-epoetin beta (at a starting dose of 120 or 200 micrograms, calculated from the last weekly dose of epoetin beta or darbepoetin alfa previously administered), or standard therapy (IV or SC epoetin beta once, twice or thrice weekly, or IV or SC darbepoetin alfa once a week or twice a week).

The purpose of this study is to compare the progression of kidney disease in subjects with Diabetes mellitus type 2 and Advanced Diabetic Nephropathy treated by routine follow-up as a general care and in subjects treated by multi-factorial intervention in the Diabetes-Renal Clinic.

Patients with reduced kidney function have a higher risk of heart disease and death. Studies have shown that blood vessels in patients with hypertension change with a decrease of lumen size and growth of the vessel wall. By treating patients with antihypertensive certain medication vessel lumen and walls normalize. Treating hypertension in patients with chronic kidney disease slows the progression of kidney function loss. The aim is to compare different degrees of antihypertensive medication in patients with chronic kidney disease and hypertension will slow the progression of kidney loss.

The Division of Kidney, Urologic, and Hematologic Diseases (DKUHD) of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), in collaboration with the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and the National Heart, Lung and Blood Institute (NHLBI) funded a cooperative agreement including two Clinical Coordinating Centers (at Children's Hospital of Philadelphia and at Children's Mercy Hospital in Kansas City), a central biochemistry laboratory (at the University of Rochester) and a Data Coordinating Center (at Johns Hopkins School of Public Health) to conduct a prospective epidemiological study of children with chronic kidney disease (CKD).
