Filter by:Contrast-induced acute kidney injury (CI-AKI) is an important adverse effect of percutaneous coronary interventions. Despite various efforts, very few preventive measures have been shown effective in reducing its incidence. The final volume of contrast media utilized during the procedure is a well-known independent factor affecting the occurrence of CI-AKI. Intravascular ultrasound (IVUS) has been largely used as an adjunctive diagnostic tool during percutaneous coronary intervention (PCI). When fully explored, IVUS provides precise information for guiding the PCI strategy. IVUS allows accurate vessel and lesion sizing, determination of plaque calcification (and the need for pre-stent plaque preparation), assessment of post-stent results (including edge dissections and residual lesion, as well as stent underexpansion or incomplete apposition). Therefore, IVUS has the potential to reduce the utilization of contrast media during PCI. In the present study, we hypothesize that IVUS guidance is associated with a significant reduction in the volume of contrast media during PCI, in comparison to standard angiography-guided intervention.
Acute renal failure is a common complication in intensive care unit patients. In 10% of cases renal replacement therapy becomes necessary. Current devices have increase filter patency and efficacy. However, magnesium, calcium and phosphate are eliminated as well. However, the extend of this elimination hase not been quantified. Thus, we want to 1. record retrospectively how often abnormal values for phosphate, magnesium and calcium occurred during routine renal replacement therapy in 2011 and 2012. 2. prospectively evaluate the same parameters during routine treatment in 2013 and 2014
Carnitine is essential for the transport of fatty acids into the mitochondria and energy production in different muscles, including the myocardium. It is also needed to protect myocyte cell membranes from oxidative damage by removing excess acyl carnitine groups. Patients receiving chronic intermittent hemodialysis (HD) are known to be at increased risk for carnitine deficiency as a result of its removal during the dialysis procedure, lack of endogenous synthesis by the kidney, and inadequate dietary intake. The carnitine status of children undergoing continuous renal replacement therapy (CRRT) has not been studied. Children undergoing CRRT in the intensive care unit (ICU) setting may be at increased risk for carnitine deficiency due to its continuous removal, lack of carnitine production by the kidney, and absence of carnitine intake (as majority of these children can not eat and there is no carnitine added to total parenteral nutrition (TPN). Carnitine deficiency may increase the risk of cardiac dysfunction in critically ill children. This is the first study to examine carnitine status in children undergoing CRRT. Standard echo as well as more sensitive speckle tracking echo will be used to evaluate the effect of carnitine deficiency on myocardial function.
The project is designed to test new biomarkers that are more sensitive than the current standard in detecting injury to the proximal kidney tubule and will establish better criteria for when kidney safety concerns may halt further testing of a drug in humans.
The purpose of this study is to determine whether the use of RenalGuard system which creates high urine output with fluid balancing may prevent contrast induced nephropathy in patient undergoing cardiac resynchronization therapy (CRT) implantation.
The purpose of the present study is to determine whether administration of aminoglycosides in septic critically ill patient is a risk factor for acute kidney injury
The best timing for renal replacement therapy (RRT) in intensive care unit (ICU) patients with acute kidney injury (AKI) is unknown. The investigators will conduct a multicenter prospective randomized open-label trial to compare two strategies in ICU patients (mechanically ventilated and/or receiving catecholamine infusion) with severe AKI defined as RIFLE F classification. These patients will be randomly allocated to one of the following strategies: 1. an "early" strategy where RRT is started immediately when a RIFLE F status is documented 2. a "delayed" strategy where RRT (in patients who also present RIFLE F renal failure) is started only in case of occurrence of one or more of the following events ("Alert Criteria"): oliguria or anuria lasting for more than 72 hours after randomization, serum urea concentration > 40 mmol /L, serum potassium concentration > 6 mmol /L, serum potassium concentration > 5.5 mmol /L that persists despite well-conducted medical treatment with at least sodium bicarbonate and / or glucose-insulin infusion, arterial pH < 7.15 in the context of pure metabolic acidosis (PaCO2 <35 mmHg) or in the context of mixed acidosis with PaCO2> 50 mmHg without possibility of lowering this PaCO2 value, acute overload pulmonary edema generating severe hypoxemia requiring oxygen flow> 5L/min in spontaneously breathing patients or FiO2> 50% in mechanically (invasive or noninvasive) ventilated to maintain SpO2> 95%, despite diuretic therapy. The primary endpoint is overall survival, measured from the date of randomization to the date of death, regardless of the cause. The minimum duration of each patient's follow-up will be 60 days.
The purpose of this study is to be able to better describe the incidence, timing and severity of myocardial dysfunction and acute kidney injury (AKI) following a documented respiratory viral illness (RSV, adenovirus, metapneumovirus, parainfluenza, influenza, etc.) in pediatric patients.

The purpose of study is to test whether perioperative sodium bicarbonate infusion can prevent acute kidney injury following open heart surgery in infective endocarditis patients.
