Background. To identify differences in sensitization to widespread allergens in patients with common allergic diseases: allergic rhinitis, bronchial asthma, angioedema, allergic urticaria and atopic dermatitis. Materials and methods. Determination of sIgE in serum using commercial and domestic reagent kits («AllergoI-FA-specific IgE» and biotinylated allergens of «Alcor Bio», St. Petersburg) was conducted in patients with allergic rhinitis, bronchial asthma, angioedema, allergic urticaria and atopic dermatitis. Results. There was a significant similarity between the spectrum of sensitization in patients with allergic rhinitis and asthma In atopic dermatitis patients the increasing of frequency of food and especially mold sensitization was estimated. The high degree of correlation between the moulds, plants and food allergens in atopic dermatitis was observed. Conclusion. The results obtained in the study can be interesting for physicians in allergological examination and for the researchers to identify new cross-reactive allergens.

The aim of our study was to evaluate the diagnostic parameters of immunoblot and Immunocap ISAC methods to determine allergic sensitization to wormwood and hazel in patients with respiratory allergic diseases – allergic rhinitis and bronchial asthma. Materials and methods. In this study, 40 patients with bronchial asthma and / or allergic rhinitis were examined with two different methods of specific allergic diagnosis (in vitro). The study was open-ended, comparative. Quantitative determination of specific IgE in the serum was performed using the RIDA® AllergyScreen immunoblot method (R-Biopharm AG, Germany) on the basis of the private laboratory of LLC “Allergy-Immunological Center KPP”. Immunocap ISAC testing was performed at “Forpost Allergy and Immunology Clinic”. Results and Discussion. Among patients, allergic sensitization to wormwood was 27.5% (11 people) in the presence of specific IgE by the Rida AllergyScreen method, 25.0% (10 people) in the presence of specific IgE using ImmunoCAP ISAC; sensitization to hazel allergen was 27.5% (11 people) in the presence of specific IgE on Rida AllergyScreen, 30.0% (12 people) in the presence of specific IgE from ImmunoCAP ISAC. For the determination of specific IgE to wormwood allergen the immunoblot has a high sensitivity and negative predictive value (100.00% in both cases) compared to ISAC, a high specificity of 96.67% (95% CI: 82.78; 99.92), but a positive predicitive value was 90.91% (95% CI: 59.28; 98.57) and accuracy was 97.50% (95% CI: 86.84; 99.94). Conclusions. Immunoblot compared to ISAC for the determination of specific IgE to hazel allergen has a relatively high specificity and negative predictive value (92.86% and 89,66%), but the sensitivity and positive predicitive value were 75.00% (95 % CI: 42.81; 94.51) and 81.82% (95% CI: 53.23; 94.68), respectively, and the accuracy of the method was 87.50% (95% CI: 73.20; 95.81).

Background and Objectives: Different types of food introduced gradually in the diet will expose children to different food allergens, increasing the chance of developing allergic diseases. The aim of our study was to determine if allergen-specific IgE values can influence, depending on the diet, the prediction of remission of urticaria in children. Materials and Methods: This prospective study was conducted in 132 patients diagnosed over two years with urticaria, admitted to “Sf. Maria” Clinical Pediatric Hospital Iaşi. Total IgE assay was performed by ELISA, and determination of specific serum IgE by the CLA System Quanti Scan method (Innogenetics, Heiden, Germany). Data were gathered and statistical analysis was performed using statistical software SPSS, using descriptive and inferential statistics. Results: The determination of specific IgE to food allergens was performed on a total of 132 cases. The values of specific IgE were positive for one or more food allergens in 84 patients (63.64%). The most common allergens involved were: cow’s milk in 33.3% cases, egg white in 22.6% cases, and hazelnuts in 11.9% cases. The specific IgE values for the different types of food included in our study had a predictive value for disease remission. Conclusions: The determination of specific IgE confirms the presence of a particular food allergen and may have predictive value for the future development of an allergic manifestation.

The aim: To study the dynamics of the level of 25(ОН)D, ІL-4, ІL-10, and IgG in the blood serum of children with allergic diseases and to study the clinical effect of vitamin D3 administration n different dosage in this category of patients. Materials and methods: 153 children aged 3-16 with such allergic diseases as bronchial asthma, atopic dermatitis and allergic rhinitis have been examined. The level of 25(ОН) D was determined using the electrochemiluminescence method, while the levels of ІL-4, ІL-10 and IgG were assessed using enzyme-linked immunoassay. Results: In the contrasting of the initial level of 25(ОН)D in the blood serum of patients after administration of 2,000 IU of vitamin D3 over 2 months, after summer and after treatment with cholecalciferol in higher doses (4,000–5,000 IU) over 2 months, significant difference was established between the indicators by the Friedman criterion (λ2 = 41.211; P < 0.05). In the similar contrasting of ІL-4 indicators, a significant difference between them was traced (P < 0.05) in the period of acute disease as well as the downward tendency in the period of remission. In the similar contrasting of ІL-10 indicators, a significant difference between them was traced (P < 0.05) in the acute period and in the period of disease remission. In the similar contrasting of IgG indicators, a downward tendency was traced in the period of acute disease and significant decrease (P < 0.05) – in the period of disease remission. In the contrasting of 25(ОН)D and ІL-4, ІL-10 figures a strong reverse correlation relationship was traced. The therapeutic effect of the administration of vitamin D3 medication in different doses in children with allergic diseases was traced. Conclusions: The data obtained shows that in the treatment of children with bronchial asthma, allergic rhinitis and atopic dermatitis the complex therapy should include vitamin D3 medications in different doses within a long-term course of treatment.

Cytokines of the interleukin-1 (IL-1) family play an important role in the realization of the protective functions of innate immunity and are the key mediators involved in the pathogenesis of a wide range of diseases, including various manifestations of allergy. The IL-1 family includes more than 11 members. However, the functions of many of them remain to be elucidated. Recently, new members of the IL-1 family have been discovered. In 2000, several independent research groups reported the discovery of a new interleukin of this family, which was named IL-37, or IL-1F7 (according to the new nomenclature). IL-37 was assigned to the IL-1 family based on its structural similarity with other members of this family. The study of its biological properties showed that its activity changes in inflammatory diseases, such as rheumatoid arthritis, psoriasis, as well as allergic diseases (allergic rhinitis, bronchial asthma, and atopic dermatitis). However, unlike most members of the IL-1 family, IL-37 acts as a negative regulator of inflammation. Activation of IL-37 suppresses inflammation, resulting in the suppression of inflammatory cytokines and chemokines, which in turn prevents infiltration of pro-inflammatory cells, mainly eosinophils and neutrophils. The exact molecular and cellular mechanisms of the anti-inflammatory effect of IL-37 in the development of allergic diseases (AD) have not been fully studied. This review summarizes and analyzes the accumulated experimental data on the role of IL-37 in the pathogenesis of AD, such as allergic rhinitis, bronchial asthma, and atopic dermatitis.

Background/Aim. Atopic diseases such as atopic dermatitis, allergic rhinitis and asthma have had increased prevalence during the past decade and nowadays occur in every third child in developed countries. The aim of the study was to determine frequency and type of atopic diseases at the age of two, as well as the importance the total IgE antibodies concentrations have in diagnosis and prognosis of the disease. Methods. The study involved 175 children up to two years of age. Allergy-like symptoms were found after surveying their parents and pediatric medical records. Using the fluorescence immunossay (FIA) method, total IgE antibodies concentrations and specific IgE antibodies (Phadiatop infant) were determined on an Immunocap 100 Dyagnostic System. Results. One or more allergy-like symptoms accounted for 57.7% of findings in children under the age of two, whilst in 19.4% the existence of IgE-related allergic diseases was found. Atopic diseases usually have clinical manifestations of atopic dermatitis (11.4%), IgE-bound wheezing/asthma (10.8%) and food allergies (7.4%), and to much lesser extent those of allergic rhinitis (3.4%) and urticaria (1.7%). The significantly higher total IgE antibodies concentrations were found in children with allergy-like symptoms (p < 0.0005) (cut-off 15.15 kU/L, sensitivity 76.5% specificity 71.6%). Conclusion. Almost 20% of two-year-old children have any of clinically manifested allergic diseases, with atopic dermatitis and IgE wheeze/asthma being predominant. The higher total IgE antibodies concentration is a good marker for sensitization in children with allergy-like symptoms.

Abstract Background Worldwide, allergy affects more than one billion people, with particularly rising prevalence in industrialised areas. Specifically, young adults appear to be predominantly targeted for an allergy diagnosis. Allergic diseases in pregnancy are mainly pre-existing but could also occur de novo. The immunological changes while pregnant, with increased Th2 lymphocyte activity, can facilitate allergen sensitisation. Objective The aim of this study was to evaluate the pattern of specific IgE (sIgE) sensitisation to common inhalant and food allergens in pregnancy, and assess its relationship to self-reported allergic disease. Methods We assessed 200 pregnant women, aged 20–38 years (mean age = 29 years), participant of ELMA (Epigenetic Hallmark of Maternal Atopy and Diet) study, living in a metropolitan area, with no pregnancy associated metabolic complications, for total IgE and allergen specific IgE to 20 allergens. Results 48% of pregnant women were sensitised to at least one allergen, at a cut-off point of 0.35 kU/L and they were assigned as atopic. However 42% in atopic group were not reporting any allergic disease. The most common inhalant allergens were: pollen (24.5%) and animal dander (23.5%). The most common food allergens were: cow’s milk (5.5%) and apples (4.5%). 7.5% of women reported asthma, 21.5% allergic rhinitis, 11.5% atopic dermatitis and 18.5% food allergy. 8.5% of were taking medication for asthma or allergies. Atopic dermatitis had the highest tendency to become more severe during pregnancy. Total IgE values were significantly higher in atopic women. Conclusions Allergic sensitisation is a common phenomenon in pregnancy. Some sensitisations could be asymptomatic. Further studies should investigate if sensitisation in mothers confers risks for immune alterations in their children.

Progress in laboratory diagnostics of IgE-mediated allergies is being made through the use of component-resolved diagnosis. The aim of our study is to analyze the sensitization profile to allergen reagents in patients suffering from atopic dermatitis with the use of the ALEX 2–Allergy Explorer and especially to show the sensitization to molecular components of molds and yeast. The complete dermatological and allergological examination including the examination of the sensitization to allergen reagents with Allergy Explorer ALEX 2 testing was performed. The relation between the sensitization to molecular components of molds and yeast and the severity of atopic dermatitis, and the occurrence of bronchial asthma and allergic rhinitis was evaluated. Altogether, 100 atopic dermatitis patients were examined—48 men and 52 women, with an average age of 40.9 years. The sensitization to Mala s 6, Mala s 11, Sac c, Asp f 6, Cla h and Cla h 8 correlates to the severity of atopic dermatitis. The sensitization to Sac c, Alt a 6, Cla h, Cla h 8 was observed significantly more frequently in patients suffering from bronchial asthma to Mala s 6 in patients suffering from allergic rhinitis. In patients with severe form of atopic dermatitis (AD), a very high level of specific IgE was recorded to Mala s 11 (in 36%) and to Asp f 6 (in 12%).

Atopic march is a variant flowing of atopia that begins in early childhood as atopic dermatitis, then developinto other allergic diseases (bronchial asthma, allergic rhinitis) at an older age. The state of the epidermal barrier and sensitization to inhaled allergens are considered as predictors for the development of atopic march. Data on the importance of these factors in the development of atopic march and information about possible approaches to prevention are presented in this article.

Allergic diseases, which have a certain stage in their development from food allergy to bronchial asthma / allergic rhinitis, are much more common in children than in adults. The aim of this study was to analyze data on the prevalence and incidence of atopic dermatitis, bronchial asthma and allergic rhinitis as components of the allergic march, in children of Ukraine from 1994 to 2017 to determine the possible impact of adverse environmental factors on their development. During the same period, due to the influence of a number of factors, in particular environmental, there were significant changes in the structure of allergic diseases making up the stages of the allergic march due to an increase in the proportion of allergic rhinitis with the reduced one of asthma and atopic dermatitis. Within 24 years, the incidence of atopic dermatitis in children aged 0-6 years including, increased by 27.6%, in adolescents - by 40.5% and significantly decreased by 39.5% in children aged 7-14 years including. Most cases of allergic rhinitis and bronchial asthma were observed in schoolchildren (47.6 and 54.0%, respectively) with a slight decrease compared to 1994. In general, allergic diseases in recent years have become more common in children from 0 to 6 years and their detection has decreased in school-age children and adolescents. Over the past 24 years, in children of Ukraine a steady increase in the incidence and prevalence of allergic diseases that form an allergic march has been noted: the prevalence of bronchial asthma has increased by 69.3% and the incidence has increased by 22.9%; the prevalence of atopic dermatitis increased by 43.9% and the incidence increased by 8.3%; the prevalence of allergic rhinitis increased by 488.3% and the incidence of allergic rhinitis increased by 380.3%, with a predominance of detection of this pathology in children from regions with developed infrastructure and industry, where there are significant emissions of pollutants into the atmosphere, that have a direct moderate effect on the increase in the prevalence of bronchial asthma, the incidence and prevalence of allergic rhinitis in children.
