Active clinical trials for "Kidney Diseases"

Cardiovascular disease is the leading cause of death and disproportionately prevalent in patients with kidney disease. Spironolactone has been shown to improve survival in the general population with heart failure by up to 30%. We wish to study the safety and tolerability of aldosterone blockade with spironolactone on cardiac function in a high risk population of patients on hemodialysis. We will study and closely monitor subjects over a period of 12 months, during which they will be receiving spironolactone for a period of 6 months.

The prevention of contrast-mediated nephropathy (CMN), which accounts for considerable morbidity and mortality, remains a vexing problem. Contrast induced renal vasoconstriction is believed to play a pivotal role in the CMN mechanism. The aim of this study is to examine the efficacy of the prostacyclin analogue iloprost (dose 1ng/kg/min) in preventing CMN in high-risk patients undergoing a coronary procedure.

The purpose of this study was to evaluate safety, not inferiority clinical and pharmacodynamic profile of the drug Enoxaparin Sodium produced by laboratory Blausiegel when compared with Clexane product, produced by Laboratory Sanofi-Aventis in 60 patients with Chronic Renal Desease.

The purpose of this study is to test whether once-weekly prozac therapy leads to reduction in depression in patients requiring kidney dialysis.

Immunoglobulin A (IgA) nephropathy is the common type of primary glomerulonephritis in the world. A wealth of literature suggests that vitamin D and its analogs have profound effects on immune system function and glomerular mesangial cell proliferation. However, calcitriol, the standard form of vitamin D, carries a substantial risk of hypercalcemia. Recently, paricalcitol (19-nor-1,25-dihydroxyvitamin D2) was approved for the treatment of secondary hyperparathyroidism in chronic renal failure, and the incidence of hypercalcemia is much lower than calcitriol. Therefore, the investigators plan to conduct a randomized cross-over study to evaluate the efficacy of paricalcitol in the treatment of IgA nephropathy. Thirty patients with biopsy-proven IgA nephropathy will be recruited. They will be randomized to paricalcitol for 12 weeks or no treatment, followed by cross over to the other arm after a washout period. Proteinuria, renal function, serum and urinary inflammatory markers will be monitored. This study will explore the potential anti-proteinuric and anti-inflammatory effects of paricalcitol in the treatment of IgA nephropathy, which has no specific treatment at present.

Deterioration of kidney renal function occurs in a minority of people due to contrast-required procedures. The purpose of this study is to compare two different interventions to reduce the risk of kidney injury after contrast medium exposition. We will perform a randomized clinical trial following a modification of a previously published protocol (Merten et al.JAMA 2004;291(19):2328-34). Patients will be randomly assigned to one of two groups of treatment. Group A will receive 1 cc/kg/hour of 0.9% saline infusion starting 12 hours before and continuing 12 hours after the procedure. Group B will receive 3 cc/kg of sodium bicarbonate solution for one hour prior to procedure, then drip rate will be decreased to 1 cc/kg/hour until 6 hours post procedure.

The advent of new, potent immunosuppressive (anti-rejection) drugs over the past ten years has substantially reduced the risk of rejection after kidney transplantation, has allowed the development of immuno-suppressive regimens that do not use long-term steroids (steroid avoidance), and has improved transplant success rates both in the short and medium term. The main new agents used in these modern regimens are the calcineurin inhibitor (CNI) tacrolimus; the anti-proliferative agent mycophenolate; and induction agents which are used to provide effective early suppression of the rejection process; these include monoclonal antibodies (MoAb) such as IL-2 receptor blocking antibodies (IL-2R MoAb: basiliximab and daclizumab) and the anti-CD52 antibody Campath-1H (alemtuzumab). Although almost all modern immunosuppressive regimens involve one or more of these agents, it is not known which is the safest and most effective combination. This randomised controlled trial compares two steroid sparing regimens which have been used with very good short and medium term results at St Mary's Hospital Renal and Transplant Unit over the last 5 years. The primary hypothesis is that the alemtuzumab/tacrolimus regimen is as effective and safe as the IL-2R MoAb/tacrolimus/mycophenolate regimen.

Patients with pre-existing kidney disease are at high risk of acute renal failure when exposed to radio-contrast dyes, for example during a cardiac angiogram. The investigators hypothesize that an infusion of saline + furosemide + mannitol will reduce rates of contrast-induced nephropathy when compared with saline infusion controls.

To determine how zidovudine (AZT) for the treatment of HIV infection is metabolized and excreted or eliminated in patients with infected or diseased kidneys. To determine the influence of hemodialysis and establish dose guidelines. AZT is the only antiviral agent with demonstrated effectiveness in patients with severe HIV infection. Persons with HIV infection may have additional health problems, one of which is a diseased kidney due to infection of the kidney, or side effects of therapy. The benefits and risks of AZT in patients with diseased kidneys are unknown. It is hoped that this study will allow further understanding of the metabolism and excretion of AZT in patients with kidney disease. AZT pharmacokinetics will be studied in patients with mild, moderate, and severe renal disorders

In people with type 2 diabetes (T2D), the body makes insulin, but cannot use it well. This results in high blood sugar levels causing damage to the blood vessels inside the kidneys. High blood pressure is a common condition that can cause damage to the blood vessels and heart if it is untreated. High blood pressure is also known as hypertension. Patients with type 2 diabetes (T2D) or high blood pressure are at a higher risk of having chronic kidney disease (CKD). In people with CKD, the kidneys become damaged and do not work as they should. Over time, the function of the kidney declines more, and this can lead to the requirement for dialysis or kidney transplantation. Most people with CKD are also at risk of heart conditions, such as heart attack or stroke. In this trial, the researchers want to learn if BAY2327949 reduces the amount of protein in the participants' urine. Protein in the urine is one of the signs of CKD. The researchers will compare the effects of BAY2327949 to a placebo. A placebo looks like the study drug but does not have any medicine in it. BAY2327949 is assumed to increase the blood flow through the kidneys, which may slow down the worsening of the disease. The researchers will use a placebo to learn if the changes seen in the participants are due to BAY2327949 or if the results could be due to chance. This trial will include about 120 men and women over the age of 45 who have CKD. The participants will have T2D or high blood pressure, and a further disease of the heart or blood vessels. During the trial, the participants will take either BAY2327949 or a placebo once a day for 28 days. The participants will visit their trial site about 9 times during the trial, and need to provide urine samples to check the participants' CKD symptoms. At the visits, the doctors will ask them if they have any health problems. They will also take blood samples to perform laboratory assessments.
