Active clinical trials for "Kidney Diseases"

The purpose of this study is to confirm the efficacy and safety results obtained in a chronic kidney disease (CKD) subgroup of patients participating in Phase III studies in a larger, independent patient population with difficult to treat gouty arthritis and moderate to severe CKD (stage 3 - 4).

The purpose of this randomized clinical trial is to evaluate the efficacy of 3 different technology-supported approaches to engaging 300 individuals with diabetes and concurrent chronic kidney disease in weight loss, dietary sodium restriction, and dietary restriction of inorganic phosphates when compared to usual care. Participants will be randomized to 1 of 4 groups, Usual Care (UC), Social Cognitive Theory-based Group Counseling (SCT), Mobile self-monitoring with tailored feedback and counseling (MONITORING), or a combination of SCT plus MONITORING conditions (COMBINED). Investigators will evaluate the intervention arms primarily in terms of weight reduction, urinary sodium excretion, and serum phosphorus and, secondarily in terms of physical activity, blood pressure, fasting lipids, medication requirements, and pulse wave velocity. Measurements will occur at baseline, 6, and 12 months. The statistical modeling of the baseline, 6 mos and 12 mos outcome variables will be based on logistic generalized linear mixed models (for binary outcomes) linear mixed models (for continuous outcomes), and random effects multinomial models (for outcomes with more than 2 levels, such as changes in medication management). In separate analyses of the intervention arm only, investigators will model self-monitoring adherence and examine possible associations between self-monitoring adherence and outcomes. The mediating effect of self-efficacy on the primary outcomes will be evaluated using structural equation models.

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.

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 determine whether lowering phosphate in patients with early chronic kidney disease with the phosphate binder sevelamer has beneficial effects on cardiovascular structure and function.

We aimed to evaluate the hypothalamus-pituitary-adrenal axis in autosomal dominant polycystic kidney disease (ADPKD) patients. Twenty two ADPKD patients and 27 healthy subjects were enrolled.

The purpose of this research is to study the effects and safety of Sensipar approved by the Food and Drug Administration (FDA) in patients with kidney failure who are being treated with dialysis and have uncontrolled secondary hyperparathyroidism (HPT).

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 compare the efficacy of oral versus intravenous hydration in the prevention of the contrast-induced nephropathy.
