BACKGROUND The clinical relevance of infections with the novel human coronavirus NL63 (HCoV-NL63) has not been investigated systematically. We therefore determined its association with disease in young children with lower respiratory tract infection (LRTI). METHODS AND FINDINGS Nine hundred forty-nine samples of nasopharyngeal secretions from children(More)
BACKGROUND Interleukin 8 (IL8) belongs to the family of chemokines. It mediates the activation and migration of neutrophils from peripheral blood into tissue and hereby plays a pivotal role in the initiation of inflammation. Thus it is important in inflammatory lung diseases like bronchial asthma or severe infections by Respiratory Syncytial Virus (RSV).(More)
Respiratory syncytial virus (RSV) is the most common viral respiratory pathogen during infancy world wide. It induces innate and adaptive immune response in host cells. The toll like receptor 4 (TLR4)/CD14 complex is particularly important for the initiation of an innate immune response to RSV. Thus we were interested whether an association exists between(More)
BACKGROUND The occurrence of allergic multimorbidity (coexistence of asthma, allergic rhinitis and eczema) has not been evaluated longitudinally from early childhood up to adulthood in a population-based study sample. We aimed to determine the prevalence of allergic multimorbidity up to age 20 stratified by parental allergies and sex/gender using extensive(More)
BACKGROUND Surfactant proteins (SP) are important for the innate host defence and essential for a physiological lung function. Several linkage and association studies have investigated the genes coding for different surfactant proteins in the context of pulmonary diseases such as chronic obstructive pulmonary disease or respiratory distress syndrome of(More)
Toll like receptors (TLRs) are an essential part of the innate immune response. So far, ten different TLRs were identified in humans. They recognize a wide range of microbial and viral pathogens. Infection by respiratory syncytial virus (RSV) is still a major health problem, about 2% of all children are hospitalised due to RSV bronchiolitis during their(More)
OBJECTIVE To analyze prevalences of allergic sensitization and atopic disease in relation to vaccination coverage. METHODS A German atopy risk-enhanced birth cohort of 1314 neonates who were born in 1990 in 5 German cities was studied. A total of 943 children participated in the follow-up visit at 5 years of age. Atopic symptoms and diagnoses (derived(More)
The aim of this study was to determine the prevalence of respiratory viruses and to prospectively evaluate the performance of the fast-track diagnostics (FTD) respiratory pathogens multiplex PCR assay shortly after the 2009/10 influenza pandemic. Highly sensitive monoplex real-time PCR assays served as references. Discrepant results were further analyzed by(More)
INTRODUCTION While preparing a graduate survey for medical education in 2008 we realized that no instrument existed that would be suitable to evaluate whether the learning outcomes outlined in the Medical Licensure Act (ÄAppO) would be met. Therefore we developed the Freiburg Questionnaire to Assess Competencies in Medicine (Freiburger Fragebogen zur(More)
BACKGROUND A novel non-invasive asthma prediction tool from the Leicester Cohort, UK, forecasts asthma at age 8 years based on 10 predictors assessed in early childhood, including current respiratory symptoms, eczema, and parental history of asthma. OBJECTIVE We aimed to externally validate the proposed asthma prediction method in a German birth cohort.(More)
