Active clinical trials for "Kidney Diseases"

The purpose of this study is to determine whether green tea or cocoa extracts are effective in improve endothelial dysfunction in patients with diabetes mellitus and nephropathy and arterial hypertension.

To assess the effects of 12 weeks of treatment with lanthanum carbonate compared with placebo on serum intact Fibroblast Growth Factor 23 (FGF23) levels.

Patients with chronic kidney disease (CKD) and albuminuria are at increased risk of developing cardiovascular disease (CVD) which is often associated with hypertension, left ventricular hypertrophy, endothelial dysfunction and increased generation of reactive oxygen species (ROS). These patients also manifest a decrease in nitric oxide (NO) availability which is thought to play an important role in their progressive vascular disease. Tetrahydrobiopterin (BH4), an essential cofactor for endothelial nitric oxide synthase(eNOS), an important regulator of NO and that is a key mediator of endothelial dysfunction. Changes in NO availability are believed to contribute to endothelial dysfunction seen in CKD and common CVD states. 6R-tetrahydrobiopterin (6R-BH4 or sapropterin dihydrochloride) is an investigational oral drug that is being evaluated to determine whether it will restore NO availability, leading to beneficial effects on vascular function and ultimately positive clinical outcomes in patients with CKD. The primary endpoint in this study is the level of albuminuria, an easily measured marker that has served as a predictor of kidney disease progression. If 6R-BH4 reduces albuminuria in patients with kidney disease, it may have implications to slow the disease progression as well as decreased risk of CVD.

Cumulative follow-up with HX575 epoetin alfa to prospectively monitor the incidence of relevant drug-related adverse events and EPO-related lack of efficacy among Chronic Kidney Disease (CKD) subjects receiving HX575 epoetin alfa i.v.

The purpose of this study is to compare the efficacy and safety of tacrolimus vs intravenous cyclophosphamide pulses treatment for the induction therapy of LN(III,IV,V). To compare the efficacy and safety of tacrolimus vs Azathioprine for the maintenance therapy of LN(III,IV,V).

Kidney disease is a fundamental part of medicine because of its prominence in Western society. Common conditions such as diabetes, hypertension and kidney infections can all progress to End-Stage Renal Disease (ESRD) also known as Stage 5 chronic kidney disease (CKD 5). Once ESRD has begun, kidney function is poor at best, thus the body is unable to effectively clear harmful toxins from the blood. A common feature of ESRD is vascular calcification, a process where blood vessels (especially arteries) attract deposits of the mineral calcium. Over time, these deposits harden and thicken in the layers of blood vessels, which limit blood flow to body tissues and can produce significant disease including hypertension, heart disease and stroke. Although the process of vascular calcification is unknown, there is mounting evidence that it is mediated by cellular events that are similar to those seen in bone formation with in the body (osteogenesis). With this point in mind, it has been suggested that agents medicine employs to limit excess bone formation will reduce the rate of vascular calcification in CKD Stage 5. This study will employ one group of drugs called bisphosphonates which have been used to limit bone formation. It will study their effect on vascular calcification in adult dialysis patients.

Diabetic nephropathy is the most common cause of ESRD and has a great impact on mortality and morbidity of diabetic patients. Despite renoprotective effect of ACE inhibitors in diabetic patients they can not hinder the progression of renal disease completely. Pentoxifylline as a TNFa blocker may hinder progression of diabetic nephropathy in combination of captopril.

PRT-201 is a protein that causes long lasting dilation of blood vessels when applied to the outside surface of the blood vessel. The purpose of this study is to determine if PRT-201, when applied to a limited segment of blood vessel immediately after surgery to create an arteriovenous fistula (AVF), is safe, dilates the blood vessel, and increases blood flow through the AVF.

This study assesses the effects of bardoxolone methyl (RTA 402) in patients with type 2 diabetes and chronic kidney disease.

This single-arm study will assess the efficacy and safety of monthly administration of SC Mircera for the maintenance of hemoglobin levels in participants with chronic kidney disease on peritoneal dialysis. Participants currently receiving maintenance treatment with SC erythropoietin stimulating agents (ESAs) will receive monthly SC injections of Mircera, with the starting dose derived from the last weekly ESA they had been receiving.
