BACKGROUND Mite allergen exposure is essential for the process of specific allergic sensitization. However, it is not clear whether incidence of specific sensitization at school age depends on the level of mite antigen exposure. Therefore the relationship between mite allergen exposure and incidence of specific sensitization was investigated. METHODS(More)
The platelet-activating factor (PAF) represents a phospholipid with complex biological functions, including involvement in inflammatory processes. The degrading enzyme PAF acetylhydrolase (PAFAH) represents a candidate for asthma and other atopic diseases. Two loss-of-function mutations of PAFAH are associated with severe asthma in Japanese individuals. Our(More)
BACKGROUND Specific predictors for atopic sensitization in early infancy are prerequisites for preventive intervention studies. OBJECTIVE To identify predictors of allergic sensitization to common aeroallergens in infancy, 1314 children in five German cities were followed up from birth (1990) to the age of 3 years. METHODS Blood samples were taken from(More)
We present 12 common polymorphisms in the coding part of the IL4 receptor gene, 5 of them leading to amino acid changes of the gene product. The IL4-receptor represents a membrane bound protein on T-cells binding the cytokine IL4 and mediating its effect. The polymorphisms and mutations described here might be useful to shed light on the structure and(More)
BACKGROUND It is unclear which exposures may cause or modify the adverse effect of rapid weight gain on fat mass development in term children whose birth weight is appropriate-for-gestational age (AGA). OBJECTIVE To determine which intrauterine or postnatal exposures increase the risk of or modify the effect of rapid weight gain on body fat percentage(More)
A number of epidemiological studies indicate that the prevalance of allergic airway diseases has been increasing over recent decades, especially in western industrialised countries, for reasons which are not yet completely understood (1, 2, 3). Changes in life style or an increase in indoor allergen exposure due to higher indoor temperature and humidity(More)
A nosocomial outbreak of rotavirus gastroenteritis involving 52 newborns occurred between June and September 1988 at the University Children's Hospital of Freiburg, Federal Republic of Germany. Stools from 27 representative patients were examined for rotavirus serotypes, using a monoclonal antibody-based enzyme-linked immunosorbent assay. The(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)
BACKGROUND Against the background of the controversial discussion about an increase in allergic rhinitis in recent years, intraindividual longitudinal data is lacking for IgE-mediated seasonal allergic rhinitis (SAR). Little is known about the development of SAR in terms of prevalence and incidence rates from birth to school age. OBJECTIVE In a(More)
BACKGROUND To describe the natural history of asthma between the ages of 7 and 10 years and to analyze risk factors for prevalences, as well as new onset of asthma-like symptoms, a longitudinal study of 1812 children was conducted. METHODS In four surveys, each 1 year apart, four asthma-like symptoms and several hypothetical risk factors were ascertained(More)
