Reliability of glomerular filtration rate estimating formulas compared to iohexol plasma clearance in critically ill children.

Unlabelled: Accurate renal function assessment is crucial to guide intensive care decision-making and drug dosing. Estimates of glomerular filtration rate (eGFR) are routinely used in critically ill children; however, these formulas were never evaluated against measured GFR (mGFR) in this population. We aimed to assess the reliability of common eGFR formulas compared to iohexol plasma clearance (CL) in a pediatric intensive care (PICU) population.

Estimation of Ontogeny Functions for Renal Transporters Using a Combined Population Pharmacokinetic and Physiology-Based Pharmacokinetic Approach: Application to OAT1,3.

To date, information on the ontogeny of renal transporters is limited. Here, we propose to estimate the in vivo functional ontogeny of transporters using a combined population pharmacokinetic (popPK) and physiology-based pharmacokinetic (PBPK) modeling approach called popPBPK. Clavulanic acid and amoxicillin were used as probes for glomerular filtration, combined glomerular filtration, and active secretion through OAT1,3, respectively.

Augmented renal clearance in pediatric intensive care: are we undertreating our sickest patients?

Many critically ill patients display a supraphysiological renal function with enhanced renal perfusion and glomerular hyperfiltration. This phenomenon described as augmented renal clearance (ARC) may result in enhanced drug elimination through renal excretion mechanisms. Augmented renal clearance seems to be triggered by systemic inflammation and therapeutic interventions in intensive care.

Impact of a VAP bundle in Belgian intensive care units.

Background: In order to decrease the incidence of ventilator-associated pneumonia (VAP) in Belgium, a national campaign for implementing a VAP bundle involving assessment of sedation, cuff pressure control, oral care with chlorhexidine and semirecumbent position, was launched in 2011-2012. This report will document the impact of this campaign.

Methods: On 1 day, once a year from 2010 till 2016, except in 2012, Belgian ICUs were questioned about their ventilated patients.

Dose optimization of piperacillin/tazobactam in critically ill children.

Objectives: To characterize the population pharmacokinetics of piperacillin and tazobactam in critically ill infants and children, in order to develop an evidence-based dosing regimen.

Patients And Methods: This pharmacokinetic study enrolled patients admitted to the paediatric ICU for whom intravenous piperacillin/tazobactam (8:1 ratio) was indicated (75 mg/kg every 6 h based on piperacillin). Piperacillin/tazobactam concentrations were measured by an LC-MS/MS method.

Impact of vancomycin protein binding on target attainment in critically ill children: back to the drawing board?

Objectives: The objectives of this observational study were to investigate plasma protein binding and to evaluate target attainment rates of vancomycin therapy in critically ill children.

Patients And Methods: Paediatric ICU patients, in whom intravenous intermittent dosing (ID) or continuous dosing (CD) with vancomycin was indicated, were included. Covariates on unbound vancomycin fraction and concentration were tested using a linear mixed model analysis and attainment of currently used pharmacokinetic/pharmacodynamic (PK/PD) targets was evaluated.

Therapeutic plasma exchange in children with acute autoimmune central nervous system disorders.

Background: There is a growing evidence for autoimmunity in acute central nervous system (CNS) disorders and treatment with therapeutic plasma exchange (TPE) may be considered. The aim was to share our experience on the clinical application of TPE in these disorders and to present a reproducible protocol which can be used even in small children.

Methods: We present a series of 8 children aged 2-12 years with transverse myelitis, Bickerstaff's brainstem encephalitis, neuromyelitis optica, and acute paraneoplastic or unspecified encephalitis in whom TPE was used as a second-line or rescue treatment.

Augmented renal clearance implies a need for increased amoxicillin-clavulanic acid dosing in critically ill children.

There is little data available to guide amoxicillin-clavulanic acid dosing in critically ill children. The primary objective of this study was to investigate the pharmacokinetics of both compounds in this pediatric subpopulation. Patients admitted to the pediatric intensive care unit (ICU) in whom intravenous amoxicillin-clavulanic acid was indicated (25 to 35 mg/kg of body weight every 6 h) were enrolled.

Possible pathogenic mechanism of propofol infusion syndrome involves coenzyme q.

Background: Propofol is a short-acting intravenous anesthetic agent. In rare conditions, a life-threatening complication known as propofol infusion syndrome can occur. The pathophysiologic mechanism is still unknown.

The long-term outcome after severe trauma of children in Flanders (Belgium): a population-based cohort study using the International Classification of Functioning--related outcome score.

Important long-term health problems have been described after severe paediatric trauma. The International Classification of Functioning (ICF) was developed as a universal framework to describe that health. We evaluated outcome in children after 'severe' trauma (defined as: hospitalised >48 h) by means of a questionnaire based on this ICF construct (IROS).

Closing the knowledge-performance gap: an audit of medical management for severe paediatric trauma in Flanders (Belgium).

Aims: Considerable variability in (paediatric) trauma care has been reported. We wanted to audit current practice in Flanders (Belgium).

Methods: The PENTA network prospectively collected data on paediatric trauma patients in a representative sample of Flemish hospitals during 2005.

Vagus nerve stimulation for refractory status epilepticus.

We report on the long-term follow-up of a patient with refractory non-convulsive SE who was successfully treated with VNS. A 7-year old girl with a medical history of thrombosis in the right internal cerebral vein and right thalamic bleeding 8 days after birth, developed epilepsy at the age of 13 months. At the age of 6 she presented with a refractory non-convulsive SE.

Paediatric trauma and trauma care in Flanders (Belgium). Methodology and first descriptive results of the PENTA registry.

Paediatric injury surveillance and prevention are definite priorities for the European, Belgian, and Flemish authorities. Current available data for Flanders (Belgium) are fragmentary and out-of-date. The PENTA registry (PaEdiatric Network around TraumA) was therefore set up to obtain recent population-based data on trauma and trauma care in children and youngsters in Flanders.

Assessing the level of consciousness in children: a plea for the Glasgow Coma Motor subscore.

Aim: The Glasgow Coma Scale (GCS) is not always easy to score and its reliability has been questioned. In adults the GCS Motor score has proven a valuable alternative, as it is easier to assess yet shows similar predictive capacity for outcome. We wanted to test the non-inferiority of the Glasgow Coma Motor score GCS-M versus the Total score GCS-T for predicting outcome in children.
