Active clinical trials for "Kidney Diseases"

The study has two objectives based on the intended-use measurements and populations described above. The first objective is to show that relative changes in impedance as measured by the test device (ΔSFI) are strongly correlated with the amount of fluid removed during dialysis (ΔF) for subjects with ESRD and possibly Heart Failure. The second objective is to demonstrate correlation between ΔSFI and relative changes in impedance (ΔZ) as measured by the reference device.

This study is a regulatory post-marketing surveillance in Japan and it is a local prospective and observational study of patients who have received Fosrenol. The objective of this research is to collect information on the safety of Fosrenol after its launching, which means collecting information on adverse events, especially adverse events in the digestive system including constipation and serious adverse events, and adverse drug reactions when the drug is administered to the below-mentioned target patients for six months. The secondary objective is to collect information on the safety of the drug when administered for more than six months, which means collecting information on the safety of the drug when administered for up to 12 months to the target patients who have already been treated with the drug for six months. And also if at the time of 12 months after administration of Lanthanum carbonate the dialysis is not conducted, extending its' administration will be continued until conduction of dialysis, or until Sept. 30, 2015. The efficacy of fosrenol is evaluated by observing the serum P(phosphorus) level and serum PTH (parathyroid hormone) level change.

The purpose of this study is to determine whether enalapril or antioxidant therapy (N-Acetylcysteine) is effective in reducing microalbuminuria in children with sickle cell disease and and its progression to sickle nephropathy

The purpose of the study is to determine if there are certain laboratory tests that can be performed to detect substances or features in a child's urine that can be used to measure the progress of Alport kidney disease and the effects of treatment. These tests and their results could be of use to measure responses to new treatments in future clinical trials.

Contrast induced nephropathy (CIN) is of great concern when using contrast media in the new era of medicine. CIN is defined as 25-50% relative increase, 0.5-1 absolute increase in serum creatinin value or 25% fall in GFR. The incidence of CIN is found to be 0% to 10% in general population and up to 50% in high risk population. High risk patients include those with chronic kidney disease (GFR<60 ml/min/1.73 m²) Diabetes Mellitus, congestive heart failure, anemia and advanced age. Amount and kind of contrast medium and decreased circulating blood volume are other important predictors of CIN. 50% of cases of CIN happen within 24 hours of contrast injection. Maximum creatinin levels are reached between 48-72 hours. It usually returns to previous levels in 7-10 days. Suggested mechanisms are renal vasoconstriction and tubular injury. N-acetylcysteine and hydration are proved to be protective against CIN and theophylline may have a role. In this study, it is hypothesized that pentoxifylline, a dimethylxanthine, can also protect renal cells from CIN. It has been observed that pentoxifylline improves oxygen delivery to ischemic tissues, diminishes oxidative damage to renal tissue and may also scavenge free radicals. Percutaneous coronary intervention is assumed a high risk procedure for developing CIN as the amount of contrast used in PCI is remarkable. Therefore, the patients undergoing PCI were selected for the trial. A prospective randomized trial will be conducted on patients undergoing PCI.

Background: Collagen IV-related nephropathies can lead to End Stage Renal Disease. Experimental studies have shown renin angiotensin aldosterone system blockade can reduce proteinuria and preserve renal function. In humans there is no proven treatment. Methods: This is a retrospective study of patients with Collagen IV-related nephropathies and proteinuria treated with enalapril analyzing the evolution of proteinuria and renal function, as well as predictive variables of progression to end stage renal disease. Outcome was creatinine clearance < 60 ml/min/1.73m2.

This prospective observational study will evaluate the safety and efficacy of Mircera (methoxy polyethylene glycol-epoetin beta) in patients with chronic renal anemia on haemodialysis in maintenance ESA treatment. Data will be collected from patients receiving once monthly Mircera according to standard of care and local labelling during 12 months of treatment.

Acute renal failure induced by radiographic contrast agents is a known complication of coronary angiography.hypoxia plays a major role in the pathogenesis of Contrast induced nephropathy. The aim of the current study is to investigate the effect of normobaric hyperoxygenation therapy on renal functions in patients at high risk for CIN undergoing coronary angiography. The study is aimed to include 180 consecutive patients with estimated GFR base on the MDRD equation of less than 60 mL/min/1.73 m2 that are candidates for elective coronary angiography. Patients with acute renal failure, acute myocardial infarction, noncompensated congestive heart failure, hemodynamic instability, known sensitivity to contrast media and patients who had been exposed to contrast media during the last 3 months will be excluded. Patients with oxygen blood saturation of less than 94% at room air will also be excluded from the study. Study protocol Patients will be randomly assigned to receive either 100% oxygen by mask (treated group) or breath room air (control group) for duration of 4 hours starting at the beginning of the angiographic procedure. All patients will be treated with 0.9% salin and NAC. Coronary angiography will be performed using nonionic, low osmolar iodine (Ultravist®-370) (Schering, Berlin, Germany). All patients will be hospitalized 1 day before and at least 24 hours following angiography. Blood samples for urea, creatinine and cystatin- C will be drawn on admission, 6, 24 and 48 hours after coronary angiography. Urine sample will be taken 24 hours before angiography and 6, 24 and 48 hours post angiography. In those urine samples the ratio between creatinine to Isoprostanes and NO will be evaluated.

The purpose of this study is to evaluate the feasibility and acceptability of two different interventions aimed at improving health outcomes among patients with chronic kidney disease (CKD), who are at high risk of CKD progression. Specifically, this study will examine how best to implement a provider-level intervention (access to a CKD-registry) and a patient-oriented intervention (automated telephone self-management (ATSM) + health coach) on patient health outcomes, with a 2x2 factorial design.

The Objective is to determine if renal hypothermia during open partial nephrectomy results in improved post-operative renal function compared to warm ischemia. Primary Aim is to determine the effect of hypothermia on preservation of overall renal function compared to no hypothermia in patients who require hilar vessel clamping during open partial nephrectomy for a renal tumor. Hypothesis: Hypothermia will result in improved post-operative preservation of overall renal function. Secondary Aim is to determine the effect of hypothermia on preservation of affected renal function (kidney with the tumor) compared to no hypothermia in patients who require hilar vessel clamping during open partial nephrectomy for a renal tumor. Hypothesis: Hypothermia will result in improved post-operative preservation of affected renal function.
