Abstract This study was conducted to determine the influence of environmental factors on the prevalence of house dust mites in student dormitories of Bandar Abbas city. In this study, 64 dust samples were collected from seven randomly selected dormitories located in various areas of the Bandar Abbas. The collected mites were isolated and mounted in Hoyer’s medium and identified using a morphological key. The associations between the environmental factors and the density of house dust mites were investigated. In total, 1,093 adult mites were collected and identified. They consisted of four species including Dermatophagoides pteronyssinus Trouessart (57.6%), Dermatophagoides farinae Hughes (24.3%) and Dermatophagoides evansi Fain (14.9%) (Acari: Pyroglyphidae), and Cheyletus malaccensis Oudemans (3.2%) (Acari: Cheyletidae). All of the dormitories were contaminated by more than one house dust mites species and the mean density of house dust mites in dormitories was 8.3 ± 0.2 mites/g of dust. There was a significant relationship between average house dust mites density and some of environmental factors such as relative humidity, temperature, floor covering type, and number of occupants (P < 0.05). Results of this study revealed that two major allergenic dust mites, D. pteronyssinus and D. farinae, were the most prevalent and collected from all of dormitories and some of indoor environmental factors found to influence mites’ population.

Allergies in dogs have become a relatively frequent topic of discussion in veterinary surgeries. Many dogs, both purebred and of mixed breeds, are diagnosed for allergies. Allergies have many causes, from genetic predisposition to the environmental conditions in which the animal lives. Allergies in dogs are troublesome because they can lead to serious health complications when diagnosed late or left untreated. The results of the study support the hypothesis that the percentage of allergies to individual allergens varied by region (Tab. 4). Differences were observed in the case of Dermatophagoides pteronyssinus and Dermatophagoides farinae house dust mites, Acarus siro, and Tyrophagus. The remaining allergens caused allergic reactions in similar percentages of dogs from northern, central and southern Poland.

Flotation Method

House dust mite was one of the most common allergens in homes around the world and associated with manifestations of allergies of skin and respiratory tract such as bronchial asthma, allergic rhinitis, and atopic dermatitis. This arthropod was commonly found on carpets, mattresses, children's toys, and other home furnishings. This study was aimed to identify and quantify the number of Dermatophagoides spp in Detention Center. This descriptive study was conducted using flotation method on 52 samples of mattress dust collected in February 2020. The results showed that 49 out of 52 mattress dust samples were positive of Dermatophagoidesspp..Of all Dermatophagoides spp, there were Dermatophagoides pteronyssinus (71.2%) and Dermatophagoides farinae (28.8%). In conclusion, this study found two species of Dermatophagoides spp. in Detention Center and suggested that the fascility maintain the cleanliness of the mattress by drying the mattress and changing the sheets at least once a week.

Abstract Background Efficacy of allergen-specific immunotherapy (ASIT) in patients with asthma could be significantly enhanced when physicians have an opportunity to identify those who are most likely to respond, determine when to stop treatment, and predict relapse. Thus, molecular allergy diagnostic is an effective tool that could help to individualize the diagnosis and treatment of asthma by accurate detection of the causative and cross-reactive allergens in pediatric patients. Cytokines are known as reliable diagnostic and prognostic biomarkers for asthma and can be used to evaluate the therapeutic effect. Objectives To evaluate the roles of molecular allergy diagnostic and biomarkers (L-10, IFNγ и TGFβ) as predictors of ASIT efficacy in pediatric patients with asthma. Design/Methods Eighty children aged 5 to 18 years with mild and moderate atopic bronchial asthma were included in the study. Sixty-eight out of 80 (85%) were found to have sensitization to house dust mites Dermatophagoides Pteronyssinus and/or Dermatophagoides Farinae. All these patients underwent molecular diagnostics using ImmunoCAP (Phadia 100) to determine the major (r Der p1, r Der p 2) and minor allergens (r Der p10) of the house dust mites. Twenty-eight patients with mild and moderate asthma were found to have a high sensitivity to these allergens and received SLIT with a mixture of house dust mites (Dermatophagoides Pteronyssinus and/or Dermatophagoides Farinae). To compare the efficacy of SLIT, we evaluated the severity of asthma clinical symptoms on a point scale from 0 to 3, and biomarker levels (IL-10, IFNγ и TGFβ) before and 6 months after SLIT. Twelve healthy children were included in the study as a reference group. Results At the beginning of the study, the average daily score in the SLIT group of 2.5 ± 0.7, and after 6 months of treatment, it decreased to 0.5 ± 0.2. The levels of biomarkers were markedly decreased prior to the treatment, especially TGFβ levels, and normalized at the end of treatment (Tab.1). Conclusion These findings support the efficacy of molecular diagnosis to determine the efficacy of allergen-specific immunotherapy in patients with asthma.
