Pyroglyphid mites are primarily associated with allergen exposure at home; hence the name house dust mites. However, we have found numerous studies reporting pyroglyhid mite levels in public and occupational settings. This review presents the findings of house dust mite allergens (family Pyroglyphidae, species Dermatophagoides) as potential work-related risk factors and proposes occupations at ...

BACKGROUND Knowledge of the domestic mite fauna and allergen levels is important for a correct diagnosis and treatment of mite allergy. Our objectives were to describe the domestic mite fauna in the region of Murcia, Spain, to quantify mite allergens in dust samples obtained from mattresses of this area and to assess the influence of geographical, climatic and dwelling factors. METHODS Dust s...

OBJECTIVE To evaluate the effectiveness of prevention measures against dust mite sensitization. DESIGN European (England, Germany, Greece, Lithuania) multicenter prospective single-blind randomized control trial with a follow-up of 12 months. PARTICIPANTS Toddlers and preschoolers, with at least 1 parent with atopic symptoms and sensitization, who initially were not sensitized to mite aller...

The aim of this study was to determine the relationship between the house-dust mite allergy and prevalence of house-dust mites in dwellings of children who were tested for specific IgE against Dermatophagoides pteronyssinus (D. pteronyssinus) and D. farinae on the suspicion of allergic rhinitis, dermatitis and asthma. All dust specimens collected from children's houses were investigated under a...

BACKGROUND It is still uncertain whether house dust mite (HDM) tropomyosin present in allergen extracts can cross-sensitize patients receiving subcutaneous immunotherapy (SCIT) and thus induce food allergy. OBJECTIVES Our aim was to assess whether new sensitization to tropomyosin occurred during HDM-SCIT, and, if so, whether it was clinically relevant. PATIENTS AND METHODS The study sample ...

Summary House dust mite allergens are common triggers for allergic rhinoconjunctivitis and asthma; they can aggravate atopic dermatitis rarely lead to anaphylactic reactions due in food. Typical symptoms nasal obstruction, sneezing, irritation, more often than pollen allergy, asthma also develops. The symptomatology exists principle throughout the year with maximum complaints autumn winter. Of ...

BACKGROUND Some studies reported the possible induction of food allergy, caused by neo-sensitization to cross-reacting allergens, during immunotherapy with aeroallergens, while other studies ruled out such possibility. OBJECTIVES The aim of this study was to evaluate the development of neo-sensitization to Pen a 1 (tropomyosin) as well as the appearance of reactions after ingestion of foods c...

One hundred and thirty-two patients known or suspected of allergy to house dust were skin-tested with pure extracts of four varieties of dust mites. The results show that both Dermatophagoides culinae and D. pteronyssinus probably played important parts in sensitizing susceptible people, as did Glycyphagus destructor and G. domesticus in some cases. In some patients these results enabled succes...
