Abstract. House dust mites are the most found allergens in homes scattered throughout the world that associated with allergic manifestations in the respiratory tract and skin, such as bronchial asthma, allergic rhinitis and atopic dermatitis. The most common house dust mite is from the family Pyroglyphidae, four of which have a close relationship with the incidence of allergy: Dermatophagoides pteronyssinus, Dermatophagoides farinae, Dermatophagoides microceras, and Euroglyphus maynei. This study aims to determine the type and density of house dust mites in several habitats in the homes of people with allergic diseases. This study is a descriptive study using cross-sectional method. Samples were dust in allergic patient’s home in Malalayang I, taken from three habitats, namely bed (mattress and bed linen), bedrooms floor and sofa, as many as 96 samples. Of the 96 samples, there are 60 samples positive of dust mites and 36 negative samples. This study found 157 mites (124 adults and 33 larvae mites). Of the 124 adult mites were identified, there are 122 from order Astigmata with the dominant species is Dermatophagoides pteronyssinus, and two others of the order Prostigmata. In each habitat that is in the bed (mattress and bed linen), bedrooms floor and sofa, Pyroglyphidae is the most prevalent.Keywords: house dust mite, allergiesAbstrak.

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.

The growth of allergic diseases dictates the need to develop new forms of therapeutic allergens with high immunogenic and low allergenic activity. For many years, our laboratory has been developing drugs for the diagnosis and treatment of house dust mites (HDM) allergies. The purpose of this study is to summarize the results of the five-year development of therapeutic preparations of HDM allergens. During this period, we obtained the following forms of therapeutic allergens: a granular sublingual dosage form of a mixed allergen from Dermatophagoides pteronyssinus (Der.p) and Dermatophagoides farinaе (Der.f) and a succinylated monomeric HDM allergoid Der.p. The physicochemical and immunobiological properties of the obtained preparations were studied by methods: electrophoresis in PAGE in the presence of SDS-sodium, micropoint immunoblot, ELISA, inhibition of the binding reaction of allergen-specific IgE in the sera of patients. The research results showed that the obtained preparations have a reduced allergenic and increased immunogenic activity in comparison with native extracts. The created forms of mite allergens can be further used to treat patients sensitized to HDM of the genus Dermatophagoides.

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.

Sharikadze O.V.Background. This study determined the efficacy of sublingual allergen–specific immunotherapy (SLIT) in Ukrainian children younger than 5 years of age with allergic rhinitis and bronchial asthma sensitized to house dust mite allergens. Methods. A cohort prospective study was conducted over a two years period with assessment of the sensitization towards inhalant allergens, measured in-vivo by wheal size and number of positive reactions on the standard skin prick test (SPT). SPSS was used to analyse any statistical correlation. Results. A total of 125 atopic asthma or/and allergic rhinitis with the mean age of 4.11 ±0.83 who were sensitized to house dust mites Dermatophagoides pteronyssinus and/or Dermatophagoides farina were included. 47 children received two-years SLIT to treat house dust mite allergies using standardized extract of sublingual allergens containing a mixture of house dust mites (Der.  pteronyssinus and Der. farinae) in the correlation of 1(0,175 НЕР):1(0,175 НЕР) (Diater, Spain). These patients were mono-sensitized with Der. pteronyssinus and Der. farinae or were SPT poly-sensitized, but these patients only had house dust mite allergy symptoms. In this group the assessment of clinical efficacy of SLIT showed the significant differences in VAS before treatment and 6 months after its receiving. The symptom “nasal obstruction” was assessed as 2.3±-1.6 points  at the beginning of the therapy, and the data reduced almost twice (1.3±-1.1); Р <0,05 after 6  months of SLIT;  then (12 and 24 months) it decreased to 0.91±0.9 and 0.34±0.5; Р <0,01, correspondingly. Conclusion. This study has shown that using of SLIT in atopic asthma or/and allergic rhinitis children under 5 year sensitized to house dust mites is an effective and safe treatment method and allows to quickly (over the first 6 months of SLIT) control the symptoms. The data of comparative analysis in the group of patients who didn’t receive SLIT has pointed to high frequency of disease symptom occurrence after the end of baseline therapy.KeyWords: sublingual allergen-specific immunotherapy, children, bronchial asthma, allergic rhinitis, sensitization, allergens, Diater  ОСОБЛИВОСТІ ЛІКУВАННЯ ДІТЕЙ ДОШКІЛЬНОГО ВІКУ, СЕНСІБІЛІЗОВАНИХ ДО АЛЕРГЕНІВ ДОМАШНЬОГО ПИЛУШарикадзе О.В.Це дослідження визначило ефективність сублингвально алерген-специфічної імунотерапії (SLIT) українських дітей молодше 5 років з алергічним ринітом та бронхіальною астмою, сенсибілізованих до алергенів пилових кліщів. Методи. Проспективне дослідження когорти проводилося протягом двох років з оцінкою сенсибілізації до інгаляційних алергенів, виміряної in-vivo за розміром пухирів і кількості позитивних реакцій на стандартному тесті на шкірі (SPT). Для аналізу статистики використовувався пакет SPSS. Результати. Обстежено 125 дітей (середній вік 4,11 ± 0,83 років) з атопічною астмою та/або алергічним ринітом, які були сенсибілізовані до домашніх пилових кліщів Dermatophagoides pteronyssinus та/або Dermatophagoides farina. 47 дітей отримали дворічний курс SLIT з використанням стандартизованого екстракту сублінгвальних алергенів, що містять суміш кліщів домашнього пилу (Der. Pteronyssinus і Der. Farinae) в співвідношенні 1 (0,175 НЕР): 1 (0,175 НЕР) (Діатер, Іспанія). Пацієнти були моносенсібіровани Dermatophagoides pteronyssinus і / або Dermatophagoides farina або були полісенсібілізовані (за SPT), однак симптоми розвивалися тільки на домашній пил. У цій групі оцінка клінічної ефективності SLIT показала значні відмінності до лікування і через 6 місяців після його отримання. Симптом «носової обструкції» оцінювався як 2,3 ± 1,6 бала на початку терапії і зменшувалися майже в два рази (1,3 ± 1,1); Р <0,05 після 6 місяців SLIT. Потім (12 і 24 місяці) він знизився до 0,91 ± 0,9 і 0,34 ± 0,5; Р <0,01, відповідно. Висновок. Дослідження показало, що використання SLIT при атопічній астмі та/або алергічному риніті у дітей до 5 років, сенсибілізованих до домашніх пилових кліщів, є ефективним і безпечним методом лікування і дозволяє швидко (протягом перших 6 місяців SLIT) контролювати симптоми.
