View clinical trials related to Acute Kidney Injury.
Filter by:Acute renal failure (ARF) is a frequent complication in the postoperative cardiac surgery, and is a major risk factor for mortality in this context. The right ventricular dysfunction post cardiopulmonary bypass (CPB) is also a common complication, close to 100% if one takes into account the transient dysfunction. A recent study showed that right ventricular dysfunction and the IRA seemed related, rather on the slope of venous congestion. We wish to study this phenomenon more specifically in particular to offer reliable diagnostic markers of venous congestion.
Contrast media-induced nephropathy following diagnostic and therapeutic cardiac catheterization.
This study evaluates the effects of aminophylline on serum creatinine and urine volume of AKI Patient.Half of participants will receive aminophylline and furosemide in combination,while the other half will receive only furosemide.
Acute kidney injury (AKI) has a frequency of 7.0 % in hospital inpatients and is especially common in critically ill patients, in whom the prevalence of acute kidney injury is greater than 40% at admission to the intensive care unit if sepsis is present. Therefore, alternative strategies are required to confer better or more complete renoprotection for those who suffered from AKI. There had been many studies demonstrated that the phosphodiesterase inhibitor pentoxifylline (PTX) is a potent anti-inflammatory, anti-proliferative, and anti-fibrotic agent capable of attenuating experimental renal disease such as drugs, ischemic and sepsis induced AKI. We thereby design this controlled, non-randomized clinical trial, aiming at investigating the potential renoprotective efficacy of PTX, as compared to placebo, in 200 patients with AKI.
Intervention: All patients at presentation would be assessed for the underlying cause of and will be managed by removal of all precipitants(careful review of medications, diuretics, nephrotoxic drugs,vasodilators or non-steroidal anti-inflammatory drugs). The second step would be to consider plasma volume expansion in patients with hypovolemia (the choice of fluid could either be a crystalloid or albumin or even blood as indicated) along with identification and early treatment of bacterial infections. Along with this patients with a differential diagnosis of HRS-AKI would be given terlipressin ( or noradrenaline/octreotide midodrine in case of contraindication to terlipressin). Patients with a clinical diagnosis of ATN would be randomized to the on-demand versus protocol-guided dialysis groups. Further, patients with urine output of less than 0.5ml/kg/hour for 4-6 hours despite adequate fluid resuscitation and vasoconstrictors would also be subjected to randomization. 1. In the on-demand group patients would get dialysis only when patient fulfills absolute criteria requiring dialysis such as metabolic acidosis with ph<7.2, hyperkalemia, refractory fluid overload (non-responsive to diuretics) or oliguria with urine output of less than 0.5ml/kg for more than 24-48 hours from the time of randomization 2. In the protocol guided group patients all patients would be considered for dialysis within 6 hours of randomization After randomization patients would receive dialysis as three sessions per week of at least 4 h with a blood flow >200 mL/min and a dialysate flow >500 mL/min in intermittent group and as 20-25 mL/kg/h of effluent, by filtration and/or diffusion in continuous form until recovery of renal functions
The purpose of this study is to investigate the association between pre-existing microalbuminuria and contrast-induced acute kidney injury (CIAKI) following coronary angiography (CAG).
The purpose of this study is to evaluate whether non-steroidal anti-inflammatory drugs (NSAIDs) were associated with acute kidney injury (AKI) in patients with heart failure. In addition, the investigators would like to assess the risk of admission for acute decompensated heart failure following exposure to NSAIDs within 30 days.
Patients with Septic AKI will be randomized in three arms, group PFD 1,200 will receive PDF 600mg every 12 hrs per mouth, group PDF 600 will receive PFD 600mg in the morning and placebo equivalent at night and Group Placebo will receive placebo every 12 hrs, all for 7 days, all receive conventional treatment KDIGO guides. We analyze the recovery of renal function as a primary objective.
This is an randomised controlled trial to investigate an strategy based in a protocol in prevention of acute kidney injury after cardiac surgery.
A recent analysis of over 4500 cardiac surgical patients at the Royal Infirmary of Edinburgh has confirmed that acute kidney injury (AKI) is not only a relatively common post-operative complication but is associated with prolonged hospital stay, and increased risk of death. There is currently no specific therapy available except supportive care. In laboratory studies, heme arginate (HA), a drug licensed for human use, has been shown to upregulate the anti-inflammatory enzyme hemeoxygenase-1 (HO-1) and protect aged mice from acute kidney injury. This study will bring this research into the human arena. It will aim to evaluate the minimum effective dose of HA and verify its safety in this specific group of patients. This will be the next step in investigating if HA could be a potential protective treatment for reducing AKI in patients about to have cardiac surgery. Patients who are due to have cardiac surgery and are aged 60 or above will be approached for inclusion in the study. If agreeable, they will be randomly assigned to receive either HA at a dose of 1mg/kg or 3mg/kg. There will be 10 patients in each group. Blood tests will be taken just before the study drug is given, at 6 hours, 24 hours and 7 days post dose. These samples will be used to examine the effect of HA on HO-1 at different doses, and will verify drug safety. Any adverse effects of the drug will be evaluated, although HA has an excellent safety profile when used as it is currently licensed for acute porphyria. Urine samples will also be collected to assess inflammation and quantify urinary biomarkers of AKI. This will set the scene for a randomised clinical trial of HA in cardiac surgical patients at high risk of AKI.
