BACKGROUND Cluster specific immunotherapy (SIT) is a modern form of allergen immunotherapy allowing safe administration of high allergen doses in a short time interval compared to classic SIT. In the current study, we investigated the safety profile and immunological effect of cluster SIT in children with allergic asthma due to house dust mite allergy. METHODS A total of 34 children (6-18 yea...

There is clear evidence that house dust mite populations in many climatic regions can potentially be controlled by modifying temperature and humidity within dwellings. This paper describes a current multi-disciplinary UK funded research project to develop a predictive model of house dust mite response to varying hygrothermal conditions. The project involves the development of two component mode...

BACKGROUND Relatively little is known about risk factors for the persistence of asthma and respiratory symptoms from childhood into adolescence, and few studies have included objective measurements to assess outcomes and exposure. METHODS From a large cross sectional study of all 4th grade school children in Munich (mean age 10.2 years), 234 children (5%) with active asthma were identified. O...

BACKGROUND Atopy is defined as the genetic propensity to develop immunoglobulin E antibodies in response to exposure to allergens and assessed by skin prick test responses to common allergens. Although it is generally agreed that atopy is an important risk factor for allergic diseases such as asthma, rhinitis, and eczema, the extent to which atopy accounts for these diseases is controversial. ...

A cross-sectional study was carried out to determine the prevalence and species of camel mange mite infestation in Raya-Azebo district, Northern part of Ethiopia. Accordingly, Three hundred and eighty-four camels were examined and mange mite infestation was detected on 64 of camels. Only Sarcoptes scabiei var. cameli was identified as the only mite species in all skin scraping samples collected...

UNLABELLED House-dust mites (HDMs) are an important source of allergens that are reputed to act as a trigger for atopic disease. Climatic conditions in parts of South Africa are not suitable for their proliferation, and there is doubt whether they occur on the Highveld. We studied whether HDMs occur in homes in Bloemfontein, Free State. METHODS Ten houses were sampled over a 1-year period. Du...

Uma vez ocorrida a sensibilização, e a asma se manifestar clinicamente, a exposição persistente aos alérgenos se associa ao aparecimento de sintomas. Portanto, quando a doença já está estabelecida, a exposição ambiental aos alérgenos oferece risco de desencadear crises, dificultando a interpretação da associação entre a asma e a sensibilização alérgica como sendo de causa e efeito. Referências ...

Euroglyphus maynei is a house dust mite commonly found in homes worldwide and is the source of allergens that sensitize and induce allergic reactions in humans. It is the source of species-specific allergens as well as allergens that are cross-reactive with the allergens from house dust mites Dermatophagoides farinae and D. pteronyssinus, and the ectoparasitic scabies mite Sarcoptes scabiei. Th...

To identify patterns of clinical history associated with extreme (high or low) probabilities of allergic sensitization in coughing children so as to restrict allergy testing to those with an intermediate probability of sensitization. A total of 752 children, aged 1-4, visiting their GPs for coughing (>or=5 days), were tested for IgE-antibodies to house dust mite, cat and dog [RadioAllergoSorben...

Background Atopic dermatitis (AD) can occur after contact with aeroallergens like house dust mites, pollen, and animal dander. Despite its controversial diagnostic value, the atopy patch test (APT) has been used as an important tool in the diagnosis of AD caused by house dust mites. Here, we present a meta-analysis comparing APT to the common skin prick test (SPT) in the diagnosis of mite-induc...
