The general objective of this open, pilot study is to characterize biological parameters related to acute kidney injury among patients undergoing a programmed coronarography with injection of contrast material. The study focuses on two main factors that may influence acute kidney injury: (1) sodium chloride hydration strategy versus sodium bicarbonate hydration strategy and (2) presence of oral L-carnitine treatment versus absence of oral L-carnitine treatment. We will also test for a potential interaction between these two factors.
The purpose of this multicentric, randomized controlled trial is to assess whether the timing of renal replacement therapy initiation (early vs delayed) has an impact on mortality at 90 days in patients with severe acute kidney injury at the failure stage (according to RIFLE criteria) during the initial phase of septic shock.
Subjects entering the study will have undergone cardiac surgery. Those who experience kidney injury within 48 hours of their surgery will be enrolled into the study. Once enrolled, subjects will receive a single administration of AC607 or placebo. Kidney recovery will be evaluated over the subsequent 30 days and death or the need for dialysis will be evaluated within 90 days of dosing. After 90 days (evaluation period), subjects will enter a 3-year extension phase of the study to monitor safety and long-term outcomes (follow-up period).
Limited prospective data is available to compare morbidity and mortality between renal replacement modalities in pediatric acute renal failure. In the absence of clear standard of care, the choice of the extra renal replacement therapy modality is subject to clinical judgement, practical aspects, and costs. This study will supply important data about usual modalities of pediatric acute extra renal replacement therapy and their impact on patient outcome and renal recovery. An obvious next step will be to conduct a randomized controlled trial comparing the different strategies.
The investigators hypothesize that transesophageal echocardiography is a valid method to obtain renal doppler hemodynamics2, 4. The goal of this study is to determine if there is a correlation between abnormal TEE resistive index measurements, intraoperative events and post-operative creatinine changes
Acute Kidney Injury (AKI) is a common clinical problem defined by an abrupt (< 48 hour) increase in serum creatinine (SCr) resulting from an injury or insult that causes a functional or structural change in the kidney. Despite significant advancements in the care of the critically ill child, mortality rates observed in critically ill children who develop AKI have not improved. The investigators have shown even "small" increases in SCr, which is the standard kidney function marker, are associated with increased child mortality, even when outcome was controlled for significant patient co-morbidity. Furthermore, the investigators have also shown that the amount of fluid accumulation observed in critically ill children with AKI is independently associated with mortality suggesting that earlier dialysis may improve survival. However, the investigators also do not want to dialyze patients who don't ultimately need dialysis, as it is an invasive procedure. The data cited above highlight the need not only to detect AKI early, but also predict it severity in order to optimize clinical decision making with respect to fluid administration and dialysis initiation. While substantial research has been expended to validate NGAL as an early marker of AKI, it has not been studied in the context of clinical decision support to guide a therapeutic intervention. The investigators hypothesize that NGAL levels can be used to determine predict which critically ill children will develop severe and prolonged AKI with substantial volume overload, thereby providing the clinician with a diagnostic tool to guide CRRT initiation.
The purpose of this protocol is to evaluate the safety of a selective cytopheretic device (SCD) in patients that are on continuous renal replacement therapy (CRRT) for acute kidney injury (AKI).
This study will assess the safety and efficacy of BCT197 on acute kidney injury in patients undergoing cardiac surgery with cardiopulmonary bypass.
Heparin is commonly used for anticoagulation of the extracorporeal circuit during continuous renal replacement therapy (CRRT) but the optimal mode of delivery has not yet been validated. Our study will compare dilute heparin to a standard concentration of heparin. The investigators hypothesize that heparin delivered in a dilute solution will augment coating of the filter fibers with anticoagulants, decreasing clotting events and increasing filter life. By improving delivery of heparin to the filter and circuit, where clotting events can disrupt dialysis, less heparin would be required for the extra-corporeal circuit and thus less heparin would be delivered back to the patient with blood return from the machine. By exposing the patient to less heparin it is hypothesized that fewer bleeding events would occur, making the dialysis treatment safer. If more of the filter's fibers remain patent and the filter is functional for a longer period of time, the CRRT would also be more effective.
