Abstract Objective The current study aims to assess the association between different characteristics of neonatal jaundice and common types of allergic diseases in childhood (as bronchial asthma, acute urticaria, and allergic rhinitis). Study Design A case-control study is conducted on 300 allergic children and 300 healthy children as a control group at Fayoum University Hospital. The study was conducted over a span of 2 years, from May 2016 to May 2018. Bronchial asthma, allergic rhinitis, and acute urticaria diagnoses were based on physician clinical examination using specific guidelines for each. For the data regarding children's demographic and maternal characteristics, a structured questionnaire was used. Regarding neonatal jaundice, data were collected from the patients' hospital records. Results Children with neonatal jaundice are more likely to develop allergy with 57% higher than neonates without jaundice. Early onset jaundice and treatment by phototherapy have statistically significant association with the development of allergic diseases. Conclusion Different aspects of neonatal jaundice are associated with the development of common allergic diseases in children.

The changing states of T cell populations responsible for the chronic course of allergic inflammation and diseases, including allergic bronchial asthma, are not yet sufficiently characterized. The aim of this study was to detect phenotypic changes in the CD45RA/CD45RO positive T lymphocytes and the level of regulatory cytokines (TNFα, IFNγ, IL-4, IL-6, IL-8, IL-10, IL-13, IL-17А, IL-17F) in allergic respiratory diseases (ARD) in children. In blood of 90 children aged 3-11 (60 children with ARD and 30 healthy peers) were studied of the immune cellular populations and cytokine indices. The levels of IL-4, IL-8, IL-10, IL-13, IL-17A and IL-17F in blood serum of children with bronchial asthma and allergic rhinitis differed from appropriate indices in control group (p = 0.001). The quantity of CD3+CD8+CD45RACD45RO+ cells, T helpers (p < 0.05) and Th effectors simultaneously expressing both isoforms of the CD45RA+ and CD45RO receptor in peripheral blood of children with ARD significantly exceeded those in control group (p < 0.001). In healthy children, Th17 population (CD3+CD4+CD196 lymphocytes) comprised 9.49±1.6% of CD3+CD4+ of cells, the number of such lymphocytes was significantly increased to 14.5±0.77 in children with allergic diseases (p < 0.001). Absolute numbers of Th17+ cells were 93.0±9.30 and 127,0±72.0 cells/µl respectively (p = 0.002). Indicators of CD4CD45RO positive memory cells in children with ARD was determined as significantly lower (p < 0.001), whereas quantity of CD3+CD19+ proved to be higher (p < 0.05) than in healthy peers. Absolute counts of these cells did not differ between the groups. The number of CD8+CD45RO+T lymphocytes was significantly higher in children with allergic diseases (p < 0.025). This research shows that the quantitative ratio of CD3+CD8+CD45RA+ and CD3+CD8+CD45RO+ populations of T cells, and increased levels of cytokines, synthesizable via Th2 and Th17, in peripheral blood may be helpful for understanding genesis of allergic respiratory diseases, and extends our knowledge on immune mechanisms of allergic disorders for individualization of therapeutic programs.

Aim: Bisphenol-A (BPA) is an endocrine disrupting compound and may exacerbate or induce allergic diseases. To the best of our knowledge, there is little evidence regarding the effects of BPA exposure on allergic rhinitis (AR) in children. In the present study, we sought to examine whether exposure to BPA in children is associated with AR. Methods: This study was designed as a case controlled clinical study. 140 children diagnosed as allergic rhinitis and 140 healthy children as control group were recruited. BPA, interleukin-4, interleukin-13, total IgE and interferon-gamma levels were determined. Skin prick tests were performed in patient group. Total nasal symptom score and ARIA classification were used to predict disease severity. Results: Serum IL-4, IgE and BPA levels of children with allergic rhinitis were found to be significantly higher than the control group. BPA and IL-4 levels were significantly higher in moderate to severe-persistent group. There was a positive correlation between total nasal symptom scores and Bisphenol A levels in children with allergic rhinitis. Conclusions: The present study is the first to observe statistically significant relationship between BPA concentrations and allergic rhinitis in children. Also increased levels of BPA are associated with disease severity.

Background and Aim. Neurogenic inflammation underlies the pathogenesis of allergic diseases. Interactions between neurons with the immune cells and structural cells (airway epithelium, nasal mucosa, skin keratinocytes) undergo altered regulation during chronic inflammation. Therefore, we hypothesized that the expression of neuroinflammatory genes may be altered allergic diseases, including atopic dermatitis and allergic rhinitis, and that, compared to atopic asthma, the expression pattern may be disease-specific in pediatric patients. Methods. In the study, we included 86 children diagnosed with atopic asthma (n=25), allergic rhinitis (n=20), and atopic dermatitis (n=20) and healthy control subjects (n=21) of Caucasian origin from the Polish population. The blood leukocyte expression of 31 genes involved in neuroinflammatory response (neurotrophins, their receptors, neuropeptides, and histamine signaling pathway) was analysed using TaqMan low-density arrays. The relative expression of selected proteins from plasma was done using TaqMan Protein Assays. Statistical analysis was done using Statistica. Results. Blood expression of 31 genes related to neuroimmune interactions showed significant increase in both allergic diseases, allergic rhinitis and atopic dermatitis, in comparison to the control group. We found 12 genes significantly increased in allergic rhinitis and 9 genes in which the expression was elevated in atopic dermatitis. Moreover, 9 genes with changed expression in atopic dermatitis overlapped with those in allergic rhinitis. Atopic asthma showed 5 genes with altered expression. The peripheral expression of neuroinflammatory genes in the human study was verified in target tissues (nasal epithelium and skin) in a rat model of allergic inflammation. Conclusions. A common pattern of neuroinflammatory gene expression between allergic rhinitis and atopic dermatitis may reflect similar changes in sensory nerve function during chronic allergic inflammation.

The aim of the research was to study the phenotype of eosinophils in children with atopic bronchial asthma and their role as diagnostic criteria of the disease. Materials and methods. We have examined 130 children aged from 6 to 18 years old with atopic bronchial asthma. The control group consisted of 40 healthy children from 6 to 18 years old, who didn’t have allergic diseases. During the research the relative and absolute levels of eosinophils, the level of eosinophils carrying FcεRI and FcεRII (CD23) – receptors were established. Results. The relative level of eosinophils in asthmatic children was 6.00% [3.00; 8.00], the absolute level – 417.00 cells/μL [232.00; 636,00], which is significantly higher compared to control group, where the relative level was 2.50% [1.00; 3.00%] and the absolute level was 166.50 cells/μl [86.00; 213.00] (p&lt;0.001). The level of eosinophils carrying the FcεRI receptor was 420,00 cells/μl [250,00; 660,00], which is significantly higher than in the control group – 200,00 cells/μl [140,00; 240.00] (p&lt;0.001). The relative level of eosinophils carrying CD23 receptor on their surface was 62.20% [35.40; 76.60] and the absolute level –223.37 cells/μl [105.30; 375.24]. The results are significantly higher than those of the control group: 25.45% [14.30; 30,60] (p&lt;0,001), and 30,88 cells/μl [25,63; 42.84] (p &lt;0.0001) respectively. It was found in the ROC-analysis that there is high evidence of presence of atopic bronchial asthma if absolute levels of eosinophils carrying CD23 receptor was 73.008 cells/μl or more or the relative index – 35.10% and more. Conclusions. The relative and absolute levels of eosinophils, as well as eosinophils carrying FcεRI and CD23 receptors are statistically significantly higher in atopic bronchial asthma than in control group patients. Increased number or relative index (73.008 cells/μl or ≥ 35.10% respectively) of eosinophils carrying CD 23 receptors can be considered as a diagnostic criterion of atopic bronchial asthma.

Allergic diseases of the respiratory system seriously affect the psychological, physical and social aspects of the live of sick children, morally and financially exhausting members of their families as well. It is known that exacerbations of allergic diseases of the respiratory tract occur due to interaction with numerous triggers, one of which is a respiratory viral infection. At the same time, it is widely known that patients with allergic respiratory diseases are more prone to to acute respiratory infections. One of the reasons for this tendency often is an insufficient activity of non-specific factors of local immunity of the respiratory system – endogenous amphiphilic antimicrobial peptides, in particular the most studied their representatives - the family of defensins and human cathelicidin. Current research proves that these antimicrobial peptides are characterized by broad antiviral, antimicrobial and immunomodulatory activity. The aim of this study was to study the concentrations of local immune factors - human HbD-2 and LL-37 - in the secretion of the mucous membranes of the upper respiratory tract in children with asthma and allergic rhinitis and to clarify their role in protection against respiratory viral infections in this contingent of patients. We performed laboratory and clinical examinations of 76 children aged 7 to 18 years, of whom 24 were diagnosed with allergic rhinitis, 28 children - bronchial asthma, and 24 - bronchial asthma and allergic rhinitis. The control group consisted of 20 healthy children of the appropriate sex and age. In addition to general clinical methods, patterns of respiratory morbidity were analyzed and concentrations of antimicrobial peptides were determined: by ELISA human cathelicidin (LL-37), β-defensin 2 (HbD-2) in the secretion of the upper respiratory tract, statistical analysis was performed. It was found that children with allergic diseases of the respiratory tract are characterized by a higher frequency of acute respiratory infections with more frequent involvement of the lower respiratory tract, which led to an increase in the duration of the disease compared to their healthy peers. In children with allergic rhinitis and bronchial asthma, there was revealed a significant decrease in the concentrations of antimicrobial peptides in the secretion of the upper respiratory tract compared with the control group.

Introduction. The study of genes that control the activity of cytokines is one of the important issues in revealing the pathogenetic mechanisms of allergic diseases. Aims. Determination of the frequency of occurrence of polymorphic gene markers genotypes and characterization of the interleukins 17A, 17F content in blood serum in children with bronchial asthma and allergic rhinitis. Materials and methods. A comprehensive survey of 110 children with allergic diseases of 311 years old and 60 healthy peers. The material for genetic analysis was DNA with the study of mutation points of IL-17A at position 197 (GA) and IL-17F 7488 (TC). The content of IL-17A, IL-17F interleukins was measured by enzymelinked assay. For the statistical analysis we used the Statistica 10, methods for comparing unrelated groups of genotypes distributions to expected values at HardyWeinberg equilibrium with 2. Results. The frequency of occurrence of genotypes in a group of healthy children was as follows: IL-17A (G197A) heterozygous GA (63,333%), homozygous GG (36,667%); IL-17F (T7488C) TT (36,667%), CT (63,333%), genotypes AA and CC werent determined. In children with allergic diseases, all genotypes were determined: IL-17A (G197A), GG (11,818%), AA (19,091%) and GA (69,091%), IL-17F (T7488C), TT (5,454%), CC (35,455%) and CT (59,091%) with the highest specific gravity of the GG genotype and TT. There were no significant differences in IL-17A, IL-17F levels in the blood serum depending on the genotype. Discussion. There were significant differences in the structure of the polymorphisms of the IL-17A, IL-17F genes, blood levels of IL-17A, IL-17F and the risk of the disease in allergic children and healthy peers. The frequency of allergic diseases in children with genotypes AA and TT is statistically higher, but with genotypes GG, CC is statistically lower than with other genotypes.

Microcirculation mechanisms and vegetative-vascular mechanisms have an important pathogenetic significance in the development of allergic inflammation.The purpose of our study was to assess capillaroscopy and heart rate variability in children with allergic rhinitis (AR), depending on the presence of comorbid pathology. All children were divided into three groups: the main group – 29 children with AR in combination with herpes infection or the presence of pathogenic microflora in nasopharyngeal swabs in the amount of more than 106, the comparison group – 23 children with AR, the control group – 26 healthy children. All children with AR had pronounced changes in the microvasculature, which varied depending on the presence of concomitant pathology, along with reactive changes in autonomic regulatory systems towards an increase in the dominance of central regulation mechanisms and the predominance of parasympathetic tone. Children with AR and concomitant pathology did not have a pronounced parasympathetic effect, in contrast to children with AR and children without concomitant pathology, which should be taken into account when drawing up a plan for personalized treatment and rehabilitation.

ABSTRACT Objective: To investigate whether there is an association between suicidal ideation (SI) and allergic diseases in adults. Methods: This was a comparative cross-sectional study involving individuals ranging from 20 to 50 years of age recruited from a university hospital in the city of Guadalajara, Mexico. We included patients with a confirmed diagnosis of allergic asthma, those with a confirmed diagnosis of allergic rhinitis, and healthy controls. All subjects completed the Beck Depression Inventory-II (BDI-II), which includes an item that evaluates the presence of suicidal thoughts or desires within the last two weeks, in order to identify SI. Results: The sample comprised 115 patients with allergic asthma, 111 patients with allergic rhinitis, and 96 healthy controls. The number of individuals identified with SI in the three groups were, respectively, 17 (14.8%), 13 (11.7%), and 8 (8.3%). Regarding the presence of SI, no statistically significant association was found in the allergic asthma group (OR = 1.98; 95% CI: 0.78-4.64; p = 0.154) or in the allergic rhinitis group (OR = 1.46; 95% CI: 0.58-3.68; p = 0.424) when they were compared with the control group. However, the presence of depression was associated with SI in the three groups: allergic asthma (OR = 12.36; 95% CI: 2.67-57.15; p = 0.001); allergic rhinitis (OR = 6.20; 95% CI: 1.66-23.14; p = 0.006); and control (OR = 21.0; 95% CI: 3.75-117.36; p < 0,001). Conclusions: In comparison with the control group, no association was found between SI and the groups with allergic diseases. In contrast, there was association between SI and depression in the three groups.
