Active clinical trials for "Kidney Diseases"

The purpose of this study is to evaluate the effect of Prostaglandin I2 analogue use on the development of chronic allograft nephropathy and changes in allograft function in prevalent renal transplant recipients

FGF-23 is a newly described protein that is an important regulator of phosphorus in the body. This protein increases in people with kidney disease and people who need dialysis have very high levels of FGF-23 in the blood. However, although some studies have indicated that FGF-23 levels go up with increased intake of phosphorus, no one knows if FGF-23 levels can be lowered in patients with kidney disease by preventing them from absorbing phosphorus from food. This study is designed to see what happens to levels of FGF-23 in the blood when patients with chronic kidney disease take medications to prevent phosphorus absorption. Since high levels of FGF-23 have been linked with increased rates of death in patients with advanced kidney disease, controlling the levels may, in the future, be a way to decrease heart disease in patients with kidney disease.

The purpose of this study was to evaluate the feasibility of individualized titration of patiromer according to serum potassium. This study also assessed the safety and tolerability of patiromer and the effects of patiromer on serum potassium in heart failure (HF) participants with chronic kidney disease (CKD).

The primary objective of this study is to evaluate the efficacy of two different doses of Pyridorin (150 mg and 300 mg)compared to placebo in retarding the progression of diabetic nephropathy. This will be assessed by measuring the change in serum creatinine and other biomarkers of kidney disease during the course of the 1-year study.

Critically ill patients frequently undergo contrast enhanced computed tomography (CT) to establish diagnoses and direct management. Contrast agents can disturb kidney function and result in kidney dysfunction. The investigators investigated the effects of high dose N-acetylcysteine (NAC) or placebo, in addition to hydration, in preventing kidney dysfunction following contrast enhanced CT) in critically ill adults in the intensive care units of two teaching hospitals.

The purpose of this study is to determine whether lowering phosphate in patients with early chronic kidney disease with the phosphate binder sevelamer has beneficial effects on cardiovascular structure and function.

The purpose of this program is to educate primary care physicians in four underserved clinics in eastern North Carolina about chronic kidney disease.

Radio Contrast Induced Nephropathy (RCIN) remains a well recognized complication in patients undergoing diagnostic or interventional procedures requiring radiographic contrast agents. Recent studies have shown benefit in administering Sodium Bicarbonate over normal saline( the uniformly accepted prophylaxy) in preventing RCIN.Therefore the aim of the study is to evaluate the efficacy of sodium bicarbonate solved in normal saline compared with infusion of normal saline in prevention of RCIN.

Anemia of inflammation is a common complication in patients with chronic kidney disease (CKD). Patients with CKD and anemia of inflammation also exhibit decreased response to erythropoietic agents, even in the presence of adequate iron stores. This decreased responsiveness is associated with increased levels of proinflammatory cytokines. Rilonacept is being developed for the treatment of inflammatory disorders. This is a clinical research study to determine the safety and effectiveness of rilonacept for the treatment of anemia in inflamed patients with CKD who are not yet on dialysis.

The purpose of this study is to study the effects of Paricalcitol (Zemplar) on kidney functioning. The investigators hypothesize that the increase in serum creatinine observed in recent paricalcitol trials is a function of reduced creatinine secretion and not an actual reduction in kidney function. 16 patients will have kidney function measured via iothalamate clearance at baseline, after 7 days of paricalcitol treatment and after 7 days of being washed off the paricalcitol.
