Active clinical trials for "Proteinuria"

This study is designed to assess the efficacy of the different dosage forms of Valsartan[80, 160, and 320 mg] in reducing microalbuminuria/proteinuria in hypertensive patients with type 2 diabetes.

Diabetic nephropathy (DN) is the most important complication of diabetes mellitus (DM) and the most common cause of end-stage renal disease (ESRD). Diabetic nephropathy is a clinical syndrome characterized by persistent albuminuria (> 300 mg/d or > 200 mcg/min) that is confirmed on at least 2 occasions 3 to 6 months apart, a relentless decline in the glomerular filtration rate (GFR), and elevated arterial blood pressure. In addition to the renal hemodynamic alterations, patients with overt diabetic nephropathy (dipstick-positive proteinuria and decreasing GFR) generally develop systemic hypertension. Hypertension is an adverse factor in all progressive renal diseases and seems especially so in diabetic nephropathy. The deleterious effects of hypertension are likely directed at the vasculature and microvasculature. Use of angiotensin converting enzyme (ACE) inhibitors and/or angiotensin receptor blockers (ARBs), strict glycemic control and use of antilipidemic drugs may improve progression of DN. TNF-like weak inducer of apoptosis (TWEAK, TNFSF12) is a member of the TNF superfamily of structurally related cytokines. The human TWEAK gene encodes a 249-amino acid type II transmembrane glycoprotein (30 kD). TWEAK may be expressed as a full-length, membrane-bound protein and as a 156-amino acid, 18-kD soluble protein, (sTWEAK) that results from proteolysis of TWEAK. TWEAK gene is expressed in many tissues, including brain, kidney, heart, arterial wall, monocytes and macrophages. Reduced soluble TNF-like weak inducer of apoptosis (sTWEAK) plasma levels have been reported both in patients with subclinical atherosclerosis and chronic kidney disease (CKD). Long pentraxin 3 (PTX3) is a multimeric inflammatory mediator. Increased serum PTX3 levels have been reported among end-stage renal disease patients. Moreover, PTX3 has been suggested to represent a novel mortality risk factor, and elevated PTX3 levels have been shown to accompany increased albuminuria among patients with chronic kidney disease (CKD). There is no data about the effects of Renin angiotensin system blockage (RAS), calcium channel blocker and combined drugs on TWEAK and PTX3 levels in diabetic proteinuric patients with hypertension. The aim of this study was to find out whether the beneficial effects of RAS blockage, calcium channel blocker and combined drugs in diabetic hypertensive proteinuric patients has any relation with the alteration of TWEAK and PTX3 levels. The investigators searched for the effects of angiotensin II (AII) receptor blocker (Valsartan 160 mg), calcium channel blocker (Amlodipine 10 mg) and AII receptor blocker plus calcium channel blocker (Valsartan 160 mg + Amlodipine 10 mg) on the clinical and laboratory parameters of diabetic hypertensive proteinuric patients.

End stage renal disease (ESRD) is rapidly growing worldwide. Patients with ESRD have increased morbidity and mortality mostly because of a dramatic excess of cardiovascular disease. Thus, preventing or limiting the progression of chronic nephropathies, in addition to limit the incidence of ESRD, may also postpone death. Drugs that inhibit the renin angiotensin system, such as Angiotensin-Converting-Enzyme inhibitors (ACEi) and Angiotensin II receptor antagonists (ATA), are reno- and cardio-protective in the long-term. There are data that statins,in addition to limit cardiovascular events may have specific reno-protective properties. Thus we designed a study aimed to evaluate whether statins associated to ACEi and ATA may have an additional reno-protective effect. ESPLANADE is a multicenter, prospective, randomized, parallel group study in which, after 2 months treatment with ACEi and ATA, two groups of 90 patients, with or without type 2 diabetes, are randomized to 6 months Fluvastatin (40 or 80 mg/day) treatment YES or NO.Twenty Italian Nephrology Units are involved in the trial. The study is fully coordinated by the Clinical Research Center for Rare Disease Aldo e Cele Daccò, Villa Camozzi, Ranica.

This is a study of whether valsartan affects levels of proteinuria in patients with type 2 diabetes and hypertension.

Taurine is a nitrogenous compound, naturally present in heart, leukocytes, retina, central nervous system, especially in muscles. It has several beneficial physiological effects like antioxidant action, and could increase muscle force contraction and insulin sensibility. Triathlon is a sport of medium to high intensity, that can causes an increase in the rate of oxygen consumption during intense exercise and consequently increases free radicals production and oxidative stress, which may compromise an athlete's performance. Due to the weekly intense training, triathletes need nutritional care ranging from calories and nutrients adequacy to the use of specific nutrients that can help to maintain health. Thus, it is believed that the use of taurine associated with chocolate milk after exercise can promote general metabolic insulin action in order to favor carbohydrates metabolism regulation, assist muscle recover and prevent oxidative damage and thus promote triathletes performance and muscle mass gain. Thus, the aim of this project is to evaluate the effects of taurine and chocolate milk supplementation in body composition, athletic performance and oxidative stress in triathletes.

The primary objective of this study is to assess the impact of proteinuria on the pharmacokinetic (PK) of a single dose of ALXN1720 in participants with proteinuria.

Background: Proteinuria develops in about 30% of kidney transplant recipients and is a strong predictor of graft loss. The amount of proteinuria has a direct correlation with the risk of graft failure. Novel therapies are urgently needed to reduce proteinuria and prevent graft loss in transplant recipients, since ACE inhibitors carry a number of limitations in the transplant setting, including significant reduction in renal function, anemia and hyperkalemia. Preliminary data: B7-1 is expressed at significant levels in about 10% of kidney allograft biopsies with predominance in patients with proteinuria. Hypothesis: We hypothesize that B7-1 targeting therapy may reduce proteinuria and improve graft survival in proteinuric transplant recipients that have B7-1 staining on allografts. In addition, the absence of CNI nephrotoxicity and the potential protective effect of Belatacept on DSA production may be of benefit in this subset of transplant patients. Objectives: Primary: Determine the effect of Belatacept conversion in reducing proteinuria by 25% at 12 months in renal transplant recipients (≥1gram/d) that are either B7-1-positive or negative on kidney biopsy. Secondary: Assess the effect of Belatacept conversion in the percent change of renal function from baseline to 12 months; donor-specific anti-HLA antibodies presence and intensity (MFI); correlation of B7-1 positivity on immunofluorescence on biopsy with B7-1-expression in urine extracellular vesicles; adverse events; acute rejection episodes; blood pressure control; new onset diabetes; hyperlipidemia; graft survival; and patient survival.

The study 'Safety and Efficacy of Paricalcitol for Reduction of Proteinuria in Kidney Transplant Recipients' is designed to assess the effects of paricalcitol in kidney transplant recipients with proteinuria. It is a single centre, randomized, placebo-controlled, double-blind clinical trial that tests the hypothesis that 24 weeks' treatment with paricalcitol compared to placebo will result in a decrease in urinary protein excretion in recipients of a kidney transplant at least three months after transplantation. Additionally, the effects of paricalcitol on albuminuria, estimated glomerular filtration rate, and blood pressure will be investigated.

This Phase 2A study is an adaptive design pilot study investigating the efficacy and safety of daily Acthar administration in diabetic patients with nephropathy and proteinuria. Patients with type 1 diabetes mellitus (T1DM) or T2DM who currently take insulin will be enrolled and randomized into 6 study groups and will be treated with either Acthar or Placebo for 36 weeks, followed by a 4 week dose taper, and a 12 week observation period. The study will compare three dose regimens of Acthar (8 U [0.1 mL], 16 U [0.2 mL], and 32 U [0.4 mL]) to equivalent volumes of Placebo to ensure the double-blind nature of the study. Insulin-requiring patients are being enrolled to aid compliance with the daily SC administration of study medication and to allow for ease of blood glucose control by adjustment of current insulin therapy in the event of glycemic excursions. Routine safety measures, including glycemic control, will be monitored throughout the study. The adaptive design component of the study allows for the re-assignment of the high dose group to the mid dose group if unacceptable toxicity is noted as per study protocol in the high dose group. Efficacy will be assessed by monitoring serum creatinine, calculated eGFR, and proteinuria (via urinary protein to creatinine ratio [PCR]). Serum cortisol concentration and additional biomarkers in blood and urine will also be monitored.

To evaluate the proteinuria lowering efficacy as well as tolerability and safety of the renin inhibitor aliskiren compared with that of placebo and angiotensin converting enzyme inhibitor perindopril in patients with non-diabetic chronic renal disease.
