OBJECTIVE Acute renal failure is a serious condition in critically ill patients, but little literature is available on acute renal failure in critically ill children. The aim of the study was to determine incidence rate, identify risk factors, and describe the clinical outcome of acute renal failure in the pediatric intensive care unit (PICU). DESIGN(More)
Cytochromes P450 3A (CYP3A) and P-glycoprotein (P-gp) are mainly located in enterocytes and hepatocytes. The CYP3A/P-gp system contributes to the first-pass metabolism of many drugs, resulting in a limited bioavailability. During the neonatal period, a shift between CYP3A7, the fetal form, and CYP3A4 occurs in the liver, but data on the expression of the(More)
BACKGROUND Recent experimental data suggest that the inflammatory response of the host to verotoxin and/or lipopolysaccharides of Escherichia coli is involved in the pathophysiology of verotoxin-producing E. coli (VTEC) infections. METHODS We measured the circulating concentrations of cytokines [TNF-alpha, interleukin (IL)-1-beta, IL-1 receptor antagonist(More)
Experimental data suggest that the host’s inflammatory response is involved in the pathophysiology of verotoxin-producing Escherichia coli (VTEC)-associated hemolytic uremic syndrome (HUS). We compared the circulating levels of pro- [interleukin (IL)-6, IL-8] and anti-inflammatory [IL-10 and IL-1 receptor antagonist (Ra)] mediators on enrollment among(More)
Nonsteroidal anti-inflammatory drugs (NSAIDs) possess antipyretic, analgesic and anti-inflammatory effects. They are frequently used in children and have numerous therapeutic indications, the most common ones being fever, postoperative pain and inflammatory disorders, such as juvenile idiopathic arthritis (JIA) and Kawasaki disease. Their major mechanism of(More)
The use of proton pump inhibitors (PPIs) has become widespread in children and infants for the management of paediatric acid-related disease. Pharmacokinetic profiles of only omeprazole and lansoprazole have been well characterised in children over 2 years of age with acid-related diseases. Few data have been recently published regarding the(More)
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT The use of intravenous pantoprazole, a proton pump inhibitor, has been increasing in the paediatric intensive care unit. Despite this increased use, data on the disposition of intravenous pantoprazole in paediatric intensive care patients are very scarce. WHAT THIS STUDY ADDS Our population approach has determined(More)
BACKGROUND Propofol is commonly used to anesthetize children undergoing esophagogastroduodenoscopy. Opioids are often used in combination with propofol to provide total intravenous anesthesia. Because both propofol and remifentanil are associated with rapid onset and offset, the combination of these two drugs may be particularly useful for procedures of(More)
Fluid administration is essential in patients undergoing hematopoietic stem cell transplant (HSCT). Admission to pediatric intensive care unit (PICU) is required for 11–29% of pediatric HSCT recipients and is associated with high mortality. The objective of this study was to determine if a positive fluid balance acquired during the HSCT procedure is a risk(More)
Verotoxin-producing Escherichia coli (VTEC) cause hemorrhagic colitis (HC) and hemolytic uremic syndrome (HUS). The aim of this study was to compare the circulating levels of transforming growth factor-beta 1 (TGF-beta1), T helper (T(H))1 (interferon [IFN]-gamma, interleukin [IL]-2), and T(H)2-associated lymphokines (IL-4, IL-13) in children with(More)
