OBJECTIVE To determine plasma levels of N-terminal pro-brain natriuretic peptide (N-BNP) in control children to establish a normal age-dependent range from the neonatal period to adulthood. In addition, plasma concentrations of N-BNP were measured in children with congestive heart failure (CHF) and correlated with ejection fraction and clinical symptoms of(More)
The aim of the present study was the investigation of N-terminal pro-brain natriuretic peptide (NT-proBNP) in the pediatric population. This is essential for adequate monitoring and classification of pediatric patients with heart disease, but no consistent data are available yet. In addition, the comparability of two commercially available NT-proBNP assays(More)
OBJECTIVE To evaluate the role of the concentration of brain natriuretic peptide in the plasma, and its correlation with haemodynamic right ventricular parameters, in children with overload of the right ventricle due to congenital cardiac disease. METHODS We studied 31 children, with a mean age of 4.8 years, with volume or pressure overload of the right(More)
PURPOSE Patients with advanced metastatic renal cell carcinoma often cannot or do not want to tolerate high-dose systemic interleukin-2 (IL-2) therapy and the toxicity associated with it. To reduce toxicity and still maintain or even increase effectiveness, we developed a method to deliver IL-2 locally for the treatment of pulmonary and mediastinal(More)
In cardiology, B-type natriuretic peptide and the amino terminal segment of its prohormone (NT-proBNP) are important biomarkers. The importance of these peptides as markers for heart disease in pediatric cardiology is reviewed. The peptide levels are dependent on age, assay, and possibly gender. The normal value range and upper limits for infants and(More)
Marfan syndrome is considered a clinical diagnosis. Three diagnostic classifications comprising first, Marfan genotype with a causative FBN1 gene mutation; second, Marfan phenotype with clinical criteria of the original Ghent nosology (Ghent-1); and third, phenotype with clinical criteria of its current revision (Ghent-2) in 300 consecutive persons referred(More)
OBJECTIVE The purpose of the study was to examine the possible age dependency of plasma N-terminal pro atrial natriuretic peptide (N-ANP) and N-terminal pro brain natriuretic peptide (N-BNP) levels in healthy term neonates to establish normal ranges for the neonatal period. METHODS N-ANP and N-BNP plasma concentrations were measured in peripheral venous(More)
The aim of this study was to characterize cardiac features of patients with neurofibromatosis 1 (NF1) and large deletions of the NF1 gene region. The study participants were 16 patients with large NF1 deletions and 16 age- and sex-matched NF1 patients without such deletions. All the patients were comprehensively characterized clinically and by(More)
Children with congenital heart disease need adequate diagnostic classification regarding their cardiovascular status (CVS). N-terminal brain natriuretic peptide (N-BNP) plasma concentration indicates dysfunction of the cardiovascular system and guides decisions concerning treatment and prognosis. Reference values are established for adults, with(More)
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT * Applying in silico tools such as population pharmacokinetic analysis and simulation will help to find adequate dosing strategies and increase the probability of success for a randomized controlled trial. * Up to now, for carvedilol in paediatric patients with congestive heart failure (CHF) the dose has been(More)
