Airway S-nitrosothiols (SNOs) are naturally occurring bronchodilators. SNOs, nitrate, and nitrite were measured in bronchoalveolar lavage fluid of 23 patients with cystic fibrosis (CF) and mild pulmonary disease (aged 6-16 years) and 13 healthy children (aged 8-15 years). Concentrations of SNOs were decreased in the lower airways of patients with CF and(More)
Patients with pyridoxine dependent epilepsy (PDE) present with early-onset seizures resistant to common anticonvulsants. According to the benefit of pyridoxine (vitamin B(6)) and recurrence of seizures on pyridoxine withdrawal, patients so far have been classified as having definite, probable, or possible PDE. Recently, PDE has been shown to be caused by a(More)
GM1 gangliosidosis manifests with progressive psychomotor deterioration and dysostosis of infantile, juvenile, or adult onset, caused by alterations in the structural gene coding for lysosomal acid beta-galactosidase (GLB1). In addition, allelic variants of this gene can result in Morquio B disease (MBD), a phenotype with dysostosis multiplex and entire(More)
It has been suggested that atopy is associated with an impairment in the delta 6-desaturation of (n-6)-polyunsaturated fatty acids and subsequently low levels of eicosanoid precursors. To evaluate this hypothesis we analyzed the fatty acid composition of plasma phospholipids and plasma cholesterol esters in a well-defined group of children with atopic(More)
Low-dose glucocorticoids (GC) achieve their action completely by classical genomic effects, mediated by the glucocorticoid receptor (GCR). In high doses of GC, nongenomic effects have also been found, but it is still unclear to what extent they contribute to a beneficial outcome. In this study, we present a determination of the number of lymphocyte GCR(More)
BACKGROUND Epidemiologic studies suggest an inverse correlation between infections and development of atopy. The purpose of this study was to test the hypothesis whether a preexisting Th1-type immune response elicited by BCG immunization could suppress allergic sensitization and airway hyperreactivity in an animal model. METHODS BALB/c mice were immunized(More)
SUMMARY. Continuous therapy with antistaphylococcal antibiotics is advocated by some cystic fibrosis (CF) centers, but it is unclear whether this strategy favors early colonization with P. aeruginosa. We used the data base for the German Centers of the European Registry for Cystic Fibrosis (ERCF) to assess the effect of continuous antistaphyloccocal therapy(More)
We report on a male proband with pyridoxine-dependent epilepsy (PDE) and neonatal seizure onset. At the age of 31 months, a prolonged status epilepticus led to severe neurological regression with cortical blindness, loss of speech and muscular hypotonia with slow recovery over the following 3 months. At 33 months of age pyridoxine therapy was initiated with(More)
Recombinant human deoxyribonuclease (rhDNase) has been shown to improve lung function and reduce the number of pulmonary exacerbations in patients with cystic fibrosis (CF), but its long-term effect on airway inflammation remains unknown. In this study, we used bronchoalveolar lavage (BAL) to investigate the long-term effect of rhDNase on inflammation in(More)
Phenylketonuria (PKU, MIM 261600) is an autosomal recessive disorder caused by mutations of the phenylalanine hydroxylase gene (PAH, GenBank U49897.1, RefSeq NM_000277). To date more than 560 variants of the PAH gene have been identified. In Europe there is regional distribution of specific mutations. Due to recent progress in chaperone therapy, the(More)
