BACKGROUND Nasya/Prevalin is a natural, drug-free nasal spray for treatment and prevention of allergic rhinitis. Because of its thixotropic property, it forms a barrier on the nasal mucosa, preventing allergen contact. This study assesses the clinical efficacy and safety of Nasya/Prevalin in a nasal provocation test with house dust mite allergens. METHODOLOGY/PRINCIPAL In this randomised, dou...

OBJECTIVE This study was conducted to determine the dust mite fauna of houses in Bitlis and Muş provinces, the monthly value of mite numbers/g dust, as well as the impact of temperature, humidity and altitude on their numbers. METHODS Dust samples were collected monthly from May 2010 to April 2011 from six houses belonging to three settlements; two of the houses were located in Bitlis, while ...

This study shows that out of 774 patients tested, the house dust mite (Dermatophagoides pteronyssinus) provoked the maximum response (51.81%) the house dust was second (42.81%), and shrimp was third (23.92%). The moderate allergenic extracts were cat fur (12.79%), dog fur (10.72%), cockroach (8.47%) egg white (7.56%) and orris powder (6.30%). Among the low allergenic extracts were Aspergillus f...

House dust mites have been shown to be strongly associated with allergic respiratory diseases such as, bronchial asthma, rhinitis and atopic dermatitis in the world. The climatic conditions of Bandar-Abbas, which is located in a coastal area and has a humid subtropical climate, provide a suitable place to proliferate mites. The aim of this study was to determine the contamination rate and analy...

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...

House dust mites are found in almost all dwellings in New Zealand and are a major risk factor in the development of asthma and perennial allergic rhinitis. We studied the longevity, life stage length, and fecundity of a New Zealand strain of European house dust mite, Dermatophagoides pteronyssinus (Trouessart), at constant (23 degrees C, 75% RH) and the fluctuating conditions typically found in...

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 For respiratory allergic disorders in children, sublingual immunotherapy has been developed as an alternative to subcutaneous immunotherapy. Sublingual immunotherapy is more convenient, has a good safety profile and might be an attractive option for use in primary care. A randomized double-blind placebo-controlled study was designed to establish the efficacy of sublingual immunothera...

mite allergens. Although mites were first grown on human skin scales collected from barber shops and on yeast [1] , other food media used included fish food flakes, dried Daphnia, dog food, rodent chow, several cereal preparations, and even mold cultures [2] . Due to their position in the trophic chain, mites mainly feed on proteins found in house and mattress dust. A supplement of yeast is als...
