There is a dose-response relation between the level of exposure to house dust mite allergen and the risk of acquiring sensitization to this allergen as well as the risk of developing asthma. This relation is apparent at levels of exposure below 10 microg/g. In communities where nearly all houses have house dust mite allergen levels above this threshold, all susceptible individuals will be affec...

The importance of the surrounding environment and ecological microcosms to determine identification mites in this particular polyester toys because these objects have necessary criteria survival reproduction different kinds mites, most people them are propitious source so that can develop atopic vulnerably or exacerbate allergic reactions. Objective: To identify dust on toys. Materials methods....

Background: Allergen sensitization, symptom severity, pulmonary function test, and bronchodilator response are important in the diagnosis treatment of asthma. However, relationship between these factors remains unclear. Objective: The objective this study was to investigate aeroallergen sensitization asthma function, among pediatric patients with bronchial Methods: This a prospective where 155 ...

Background Infants with family history of atopy are considered at high risk for developing allergic disease. Environmental exposures are modifiable risk factors with a potential for intervention to prevent allergy. Children who develop house dust mite (HDM) sensitisation by pre-school age are at higher risk of developing asthma. Prevention of HDM sensitisation in early childhood by immune modul...

OBJECTIVE To determine the use and efficacy of sublingual immunotherapy (SLIT) for house dust mite (HDM) allergies in Southeast Asian children. DATA SOURCES Aliterature search was performed in Pubmed and the Asian Pacific Journal of Allergy and Immunology. We also evaluated the literature for similar studies performed in Asia. STUDY SELECTIONS Clinical trials involving children that assess ...

INTRODUCTION In Portugal, data on the role of Der p 1 and Der p 2 in patients with house dust mite (HDM) allergy are scarce. Allergen-specific immunotherapy (sIT) is the only treatment that improves symptoms, reduces the need for pharmacological therapy and modifies the natural history of the disease. With this study, the authors aim to understand the local epidemiology and to clarify if the mo...

BACKGROUND There is debate as to whether asthma has distinct atopic and non-atopic forms and whether in epidemiological studies asthma cases should be defined by a physician diagnosis or by self-reported asthma symptoms. METHODS A total of 24,952 people aged 11 and over were surveyed as part of the 1995-6 health surveys for England. Participants were asked if they had experienced wheezing in ...
