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. 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.

Asthma is a common problem that affects about 20 million peoples in India and can be often under-diagnosed or misdiagnosed. It can be allergic or non-allergic though the former type is more common and prevalent. Allergic asthma can be triggered by many allergens and house dust mites (HDM) are one of the common indoor allergens. The present study emphasizes the significance of house dust mites in allergic asthmatic subjects which is based on 115 asthmatic subjects in Punjab, India. For the quantification and the estimation of total serum Immunoglobulin E and HDM specific IgE, a mixture of 14 allergens and a mixture of two mite allergens viz. Dermatophagoides pteronyssinus and D. farinae were used respectively. Total and specific IgE levels were detected on ImmunoCAP Phadia 100. A statistically significant correlation between total and HDM specific IgE levels of 115 asthmatic subjects was found as compared to control group of 30 non-allergic individuals. The specific IgE levels of 54.78% subjects against the allergen of two mite species were found to be positive. Dust samples were taken from various localities of the houses to identify the diversity of house dust mites which were responsible for allergic asthma. Five common house dust mite species viz. D. pteronyssinus Trouessart, D. farinae Hughes, D. microceras Griffiths and Cunnington, D. aureliani Fain and Euroglyphus maynei Cooreman were identified from the dust. The present study observed that total IgE levels were higher with higher specific IgE levels against the mixture of two mite allergens viz. D. pteronyssinus and D. farinae in the blood serum.  D. pteronyssinus was the most abundant and prevalent mite species followed by D. farinae. Therefore, present study concluded that HDM specific IgE levels against the mite allergen of D. pteronyssinus and D. farinae in the serum of allergic asthmatic subjects were found to be higher because of the higher prevalence of these two mites (D. pteronyssinus i.e. 69.80% and D. farinae i.e. 20.72%) in the house of allergic asthmatic subjects as compared to other identified mites.

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.

House dust mites produce potent allergens that exacerbate asthma in sensitized patients, whom are recommended to practice allergen avoidance within their home environment. We tested the effect of activated charcoal impregnated fibers on house dust mite survival. One hundred live adult house dust mites (Dermatophagoides pteronyssinus) were added to eight culture dishes preequilibrated at room temperature () and 70% humidity () containing house dust mite food and active charcoal fibers. At 10 minute intervals, live and dead house dust mites were counted. All house dust mites instantly attached to the activated charcoal fibers and started to shrink almost immediately. There were no live house dust mites present as early as 40 minutes in some dishes while after 190 minutes all house dust mites were dead. In conclusion, activated charcoal fibers, if incorporated into bedding items, have the potential to control house dust mites in the indoor environment.
