Twenty one adult patients with asthma, with positive skin test responses to the European house dust mite, Dermatophagoides pteronyssinus, were randomly allocated to a control group or to a group applying house dust mite avoidance measures. These included an initial application of liquid nitrogen to mattresses and bedroom carpets to kill the live house dust mite population. Histamine airway resp...

Serum levels of total IgE, specific IgE, IgG and IgG4 against house dust mite were measured in mite-sensitive asthma patients receiving immunotherapy with house dust. Serum levels of total IgE, mite specific IgE and IgG did not significantly change during the course of hyposensitization. Increased levels of mite specific IgG4 were observed in patients during immunotherapy. The increase in speci...

BACKGROUND Chronic urticaria is one of the perplexing problems faced by clinicians. There are a few reports associating house dust mite sensitivity with chronic urticaria, based upon the patient's history as well as intradermal skin testing and in vitro analysis. AIMS To investigate the possible association between house dust mite sensitivity and chronic urticaria. METHODS In this case cont...

BACKGROUND Sublingual immunotherapy (SLIT) as a therapy for the treatment of allergic rhinitis in children might be acceptable as an alternative for subcutaneous immunotherapy. However, the efficacy of SLIT with house dust mite extract is not well established. OBJECTIVE To investigate whether SLIT in house dust mite-allergic children recruited in primary care is effective and safe. METHODS ...

Allergic rhinitis (AR) is a common, frequently occurring disease with increasing incidences every year. House dust mite is one of the common indoor allergens that causes allergic rhinitis. So this study was aimed to evaluate the efficacy and safety of Allergopharma house dust mite vaccine in the treatment of allergic rhinitis. A case self-control method was used to compare the total symptom usi...

House dust mite allergens express protease activity and it has been suggested that this property has pathogenic effects by increasing airway absorption. In accordance, house dust mite allergens may increase mucosal permeability in vitro. The objective of the present study was to examine nasal absorption of desmopressin (1-deamino-8-D-arginine vasopressin) in patients with perennial house dust m...

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...

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 ...

House dust mite sensitized asthmatics are advised to practice allergen avoidance. Charcoal pillows are used in Korea with unsubstantiated claims regarding their efficacy in alleviating asthma symptoms. We tested the effects of activated charcoal on breeding of house dust mites in culture. Twenty live adult house dust mites (Dermatophagoides pteronyssinus) were inoculated, 10 replicates, on cult...

Background Seafood is one of the most important causes of anaphylaxis worldwide and considered to be closely associated with house dust mite allergy due to cross-reactivity of mite trypomyosin (Der p 10) with the tropomyosins from shrimps and molluscs. We assessed the prevalence of sensitization to tropomyosin and other shrimp allergens in seafood-allergic subjects from Central Europe and explo...
