the aim of this study was to identify the species and prevalence of house dust mites (hdms) in kindergartens in bandar abbas, south of iran. in this study 10 kindergartens were selected randomly in five areas of bandar abbas. two dust samples were collected from each sampling place with a vacuum cleaner. mites were isolated and mounted in hoyer's medium and identified using a morphology-based k...

BACKGROUND House dust mite avoidance is advised in dust mite sensitized patients to decrease the risk to develop allergic symptoms. Maintaining a relative humidity (RH) of less than 50% in households is recommended to prevent dust mite proliferation. OBJECTIVE To investigate the efficacy of a novel temperature and humidity machine to control the level of dust mite allergens and total nasal sy...

BACKGROUND The house dust mite is the most important environmental allergen implicated in the aetiology of childhood asthma in the UK. Dust mite barrier bedding is relatively inexpensive, convenient to use, and of proven effectiveness in reducing mattress house dust mite load, but no studies have evaluated its clinical effectiveness in the control of childhood asthma when dispensed in primary c...

We studied the amount of house dust antigen in the beds of 55 patients with atopic dermatitis, eleven patients with psoriasis and ten healthy volunteers using a commercial ELISA which can determine the amount of antigen from Dermatophagoides pteronyssinus, D. farinae and D. microseras expressed as nanogram (ng) antigen per gram of house dust. The World Health Organization has indicated that 10,...

BACKGROUND Although exposure to house dust mite allergen is a major risk factor for allergic sensitization and asthma, nationwide estimates of dust mite allergen levels in US homes have not been reported. OBJECTIVE The purpose of this study was to estimate the prevalence of dust mite allergen in beds of US homes and to identify predictors of dust mite allergen concentration. METHODS Data we...

A significant-source of allergens come from house dust that contain particles derived from arthropods, molds, and pet dander. This study evaluated mite and booklouse fauna from vacuumed dust samples in Beijing China (a temperate zone). Our survey was carried out in Beijing in the homes of mite allergic patients who visited our Allergy Department. In total, 38 homes were selected for the collect...

BACKGROUND Up to 70% of atopic asthmatics have a positive skin test to the dust mite allergen Der p 1. Reduction of dust mite numbers by lowering room humidity control is one suggested technique for reducing dust mite allergen levels to clinically acceptable levels. Trials of this technique in temperate climates have reported mixed results. It has been speculated that one reason for this is tha...

Bedding dust is a mixture of many components, of which the house dust mite (HDM) allergen, Der p 1, is the most allergenic. There has been little work to investigate the effect of other bedding dust components on HDM sensitisation. The objective of the study was to determine the effect of endotoxin in bedding dust on the allergic response in HDM-sensitised individuals. Twenty-nine house dust mi...

background: being exposed to house dust mites intensifies atopic dermatitis. this study has investigated the con­tamination rate with dermatophagoides mites in patient's residential home with atopic dermatitis. methods: in this cross-sectional study, 40 patients took part with atopic dermatitis (positive or negative for mites by prick dermal test). samples were collected from 3 locations (livin...

BACKGROUND Prenatal exposure to both stress and aeroallergens (dust mite) may modulate the fetal immune system. These exposures may interact to affect the newborn immune response. We examined associations between prenatal maternal stress and cord blood total IgE in 403 predominately low-income minority infants enrolled in the Asthma Coalition on Community, Environment, and Social Stress (ACCESS...
