The human coronavirus NL63 (HCoV-NL63) was first identified in The Netherlands, and its circulation in France has not been investigated. We studied HCoV-NL63 infection in hospitalized children diagnosed with respiratory tract infections. From November 2002 to April 2003, we evaluated 300 respiratory specimens for HCoV-NL63. Of the 300 samples, 28 (9.3%)(More)
A method was developed for the quantitation of respiratory syncytial virus (RSV) based on real-time RT-PCR using a LightCycler instrument. A control real-time RT-PCR was undertaken on GAPDH mRNA (a human housekeeping gene) was carried out to standardise the non-homogeneous respiratory samples. The real-time RT-PCR method was one log more sensitive for the(More)
OBJECTIVES Progression and severity of lung disease differs markedly and early between patients with cystic fibrosis (CF). We investigated the hypothesis that polymorphisms in the detoxifying enzymes glutathione-S-transferase (GST) could influence phenotypic presentation of lung disease in CF. METHODS Genotypes for GSTM1, GSTM3, GSTP1 and GSTT1 were(More)
ABCA3 (ATP-binding cassette subfamily A, member 3) is expressed in the lamellar bodies of alveolar type II cells and is crucial to pulmonary surfactant storage and homeostasis. ABCA3 gene mutations have been associated with neonatal respiratory distress (NRD) and pediatric interstitial lung disease (ILD). The objective of this study was to look for ABCA3(More)
Human metapneumovirus (hMPV) is responsible for respiratory tract disease, particularly in the young and elderly population. An epidemiological and phylogenic study was performed on children admitted to hospital with an acute lower respiratory tract infection (LRI). Data were obtained and analyzed over three consecutive winters, from 2002-2003 to 2004-2005.(More)
Primary endobronchial tumors are rare in children and they include a broad spectrum of lesions. The aim of this study was to determine the characteristic features, treatments and outcomes of these tumors. We report a retrospective analysis of all patients treated for endobronchial tumor in nine French hospitals between 1990 and 2010 and a comparison of the(More)
The performances of four multiplex PCR (m-PCR) were compared to direct immunofluorescence assay (DFA) and HuH7 cell culture for the detection of viruses in 263 children admitted to hospital with an acute respiratory illness. One hundred fifty (57.6%) nasal aspirates were found DFA-positive; 188 (72.3%) were found positive by both DFA and HuH7 cell culture,(More)
Incidence of resistance to erythromycin at our institution reached 53% in 122 Staphylococcus aureus isolates obtained from patients with cystic fibrosis (CF) from 1997 to 1999. Macrolide-resistance genes were sought for in 20 erythromycin-resistant isolates from 9 patients with CF by use of polymerase chain reaction; 13 strains did not contain any known(More)
BACKGROUND A high frequency of virus infections has been recently pointed out in the exacerbations of asthma in children. OBJECTIVES To confirm this, using conventional and molecular detection methods, and expanding the study to younger children. STUDY DESIGN One hundred and thirty-two nasal aspirates from 75 children hospitalized for a severe attack of(More)
Recent evidence suggests that genetic polymorphisms that affect the production of interleukin (IL)-10 may play a role in the response to pathogens in cystic fibrosis (CF). The present study was designed to investigate a possible association between alleles carried at position -1082 in the promoter region of the IL-10 gene and clinical data on 378 patients(More)
