Savvo3 1 Kharkiv National Medical University, Kharkiv, Ukraine 2 Ecomed Medical Center, Kharkiv, Ukraine 3 Municipal non-profit enterprise of Kharkiv Regional Council «Regional Children’s Clinical Hospital G1», Kharkiv, Ukraine Abstract. The aim of the work is to determine the molecular profile of sensitization to house dust mites in children with bronchial asthma in the Kharkiv region. Object and methods of study. 42 children aged from 6 to 18 years were under observation. Evaluation of the sensitization profile was performed by the method of multicomponent photometric analysis ALEX. Results and discussion. Boys predominated among the patients — 76 %. Patients had intermittent (46 %), mild persistent (31 %), moderate persistent (15 %) and severe persistent asthma (8 %). Allergic rhinitis was noted in 88 % of patients. Elevated IgE levels were observed in 69 % of patients. The median IgE is 385.50 [122.75; 991.00] kU/L. Sensitization to house dust mites was detected in 23 (54 %) patients, of which monosensitization — 10 %; co-sensitization with other aeroallergens — 44 %. Among pediatric patients in the Kharkiv region, the leading sensitization is sensitization to D. farinae (44 %) and D. pteronyssinus (48 %). Molecular sensitization profile: Der f1 — 38.1 %; Der f2 — 38.1 %; Der p1 — 33.33 %; Der p2 — 38.1 %; Der p5 — 14.29 %; Der p7 — 16.67 %; Der p10 — 9.52 %; Der p20 — 2.38 %; Der p23 — 26.19 %. Only minor components (Der p5, 7, 10, 20 or 21) were found in 7.14 % of patients, which proves the need for molecular diagnosis when prescribing immunotherapy. Among the «new» allergens for our region — Blomia tropicalis — sensitizationin 11.9 %; molecular profile: Blo t1 — 2.38 %; Blot 10 — 9.52 %; Blo t21 — 4.76 %. Isolated cases of sensitization to ticks Glycyphagus domesticus, Tyrophagus putrescentiae, Lepidoglyphus destructor have been identified. Conclusions. Differences in sensitization to molecular components of house dust mites in children of the Kharkiv region were proved . It should be taken into account in the diagnosis and treatment of patients with allergic diseases. Key words: bronchial asthma, sensitization, house dust mites, molecular components.

Abstract HDM (House dust mites) are important environmental trigger factors of airway allergic diseases, the allergens of HDM were detected in the human gut mucosa, which induces local inflammation and increases intestinal permeability. This study tests a hypothesis that house dust mites contribute to the development of OVA (ovalbumin)-induced food allergy. The serum levels of IgE against HDM in patients with food allergy were detected with UniCAP100 (Pharmacia, Uppsala, Sweden); the HDM-induced/the OVA-induced mouse model of food allergy was developed. Difference between 2 groups was determined by Student t test or ANOVA if more than two groups. Compared to the healthy controls, the patients with food allergy have higher levels of serum IgE against HDM. Compared to food allergy alone groups, the levels of IgE against HDM in food allergy with asthma or allergic rhinitis groups were increased significantly. In mouse models, we found that HDM/OVA induced allergy-like symptoms, lower body temperature, and lower body weight. The levels of IgE, IgG1, mMCP-1 (mouse mast cell protease-1), IL-4 and IL-5 in the HDM and HDM + CT (cholera toxin) groups were higher than the control groups, and the levels of IgE, IgG1, IL-4 and IL-5 in the HDM, OVA and HDM + OVA groups were higher than the control groups. The pathology of intestinal tract in the HDM and HDM + CT/the HDM, OVA and HDM + OVA groups were more severe and exhibited more eosinophils than the control groups. Moreover, the prior exposure to HDM induced intestinal barrier dysfunction, and facilitated the development of intestinal allergy in mice. Based on above data and previous researches, we put forward that HDM exposure enhances subsequent responses to OVA-induced food allergy.

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.

Dermatophagoides pteronissinus, Dermatophagoides farinea and their products of vital activity are the main allergenic components of house dust. The only pathogenetic and effective method of treatment of patients with house dust mites induced allergic rhinitis and atopic bronchial asthma according to positions of evidencebased medicine is allergenspecific immunotherapy (ASIT) with house dust mites (Dermatophagoides pteronissinus, Dermatophagoides farinea) allergens. Modern data on prevalence of a sensitization to house dust mites at patients with respiratory manifestations of allergy are presented in the review, questions of carrying out ASIT by various methods with application of the standardized allergens, its efficiency and safety are discussed.

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.
