The diagnostic significance of bronchophonography (BPG) for early detection of bronchial asthma (BA) in children from 2 to 5 years old is estimated. BPG was used to examine 210 children, including 110 children with often acute respiratory infections (ARIs), 35 children with the mild case of BA in the remission period, and 65 practically healthy children. In patients with BA compared to the group of practically healthy children, the indices of acoustic work of respiration in the high-frequency range (the so-called zone of obstructive changes) were increased, and this increase was reversible after pharmacological test with a bronchial spasmolytic. Similar changes of BPG were observed in 20% of patients with often ARIs, and two years later these children had typical clinical signs of BA. Indices of diagnostic sensitivity and specificity of BPG were equal to respectively 95.2 and 95.0%. Taking into account the relative simplicity and noninvasive character of BPG, this allows us to recommend the wide use of this method as a screening one for early diagnostics of BA in children of early and preschool age under hospital conditions.

Background. To study the role of NO metabolites in allergic inflammation regulation and remodelling in BA patients. Material and methods. Morphological and morphometrical methods of investigation of bronchi mucous of 39 BA patients were used, IL-4, TNF-α, INF-g, IL-8, nitrite, 3-nitrotyrosine, nitrosoglutathion levels in bronchoalveolar washout were investigated, nitrite concentration in condensate of the exhaled air was measured. Results. The increased level of IL-4, TNF-α, INF-g, IL-8 in bronchoalveolar washout is associated with persistent Th2-inflammation. The BA severity correlate with highest IL-8, TNF-a, INF-g, nitrite and 3-nitrotyrosine level but with nitrosoglutathion deficit and in general is associated with structured architectonics bronchi mucous abnormalities. Conclusion. The association of toxic NO metabolites, pro-inflammation cytokines levels, bronchi mucous path-omorphological abnormalities with clinical signs of BA confirms the role of toxic NO metabolites in development of Th2-inflammations.

Aim: to study the diagnostic significance of volume capnography in examination of patients with severe and moderate bronchial asthma (BA). Materials and Methods. 171 patents were examined, of them 43 patients with severe BA and 45 patients with moderate BA. The control group included 83 relatively healthy volunteers. In all the participants, along with clinical examination, parameters of spirometry and volume capnography were determined using ultrasound computer spirograph SpiroScout (Ganshorn, Germany) equipped with a volume capnography function. Results. Volume capnography revealed the following changes in patients with BA in comparison with the control group: increase in the slope of phase III (indicates non-uniformity of ventilation and perfusion in the lung periphery due to pathology of the small airways) and increase in emphysema index (indicates hyperinflation of lung). The above indices had statistically significant differences in severe and moderate asthma. Based on the results of examination of healthy individuals, the normal values for the slope of phase III (<0.31 g/mol·L) and emphysema index (<43) were calculated. Diagnostic sensitivity and specificity of volume capnography were studied with subsequent construction of ROC-curves and calculation of AUC for the slope angle of phase III and for emphysema index. It was found that most informative in BA are parameters of specificity of the diagnostic test (slope of phase III – 90.32%, emphysema index – 96.77%). The subsequent construction of ROC-curves showed that the AUC value for slope of phase III and emphysema index was higher in severe BA compared to the moderate BA (0.74 and 0.86, respectively). Conclusion. The obtained data demonstrate the significance of volume capnography in the functional diagnosis of respiratory disorders in BA.

Children with clinical signs of immunocompromise have impaired functioning of the immune system. At the same time, the state of subpopulations of multifunctional neutrophil granulocytes (NG), which provide antiviral and antibacterial protection, in such patients has been poorly studied. Objective of the study: to assess the features of the transformation of the phenotype of the three most significant subpopulations of NG, their association with impaired phagocytic and microbicidal activity in immunocompromised children with atypical viral-viral co-infections and bacterial infections, and to clarify their differential diagnostic significance. Materials and methods of research: the phenotypes of NG subpopulations expressing CD64, CD32, CD16, CD11b receptors, phagocytic and microbicidal activity of NG were studied in the peripheral blood of 43 immunocompromised children of both sexes aged of 5–9 years old suffering from recurrent ARVI, atypical chronic mono – or mixed herpes virus infections (HVI) and purulent bacterial infection. 3 study groups were formed: 1st – repeated ARVI/HVI mono, 2nd – repeated ARVI/HVI mixed, 3rd – minor purulent infection (MPI) and a comparison group (20 apparently healthy children). Results: different differentiated transformation of the phenotype of functionally significant subpopulations of NG associated with impaired functional activity of NG as well as with the incidence of viral co-infections (repeated ARVI and recurrent HVI mixed) and the severity of clinical manifestations of MPI has been identified in the studied groups. Conclusion. Еvaluation of the features of transformation of phenotype of NG subpopulations, their effector functions in immunocompromised children with atypical viral-viral co-infections and purulent bacterial infections, will allow in the future to optimize the methods of target immunotherapy aimed at remodulating the negatively transformed phenotype of NG subpopulations, correcting their dysfunctions and, thereby, significantly increase the clinical effectiveness of therapeutic and preventive measures.

Bronchial asthma as the most common respiratory tract disease is an urgent problem of modern medicine. Matrix metalloproteinases (MMР) play a significant role in the processes of inflammation maintaining and bronchi remodeling in children with bronchial asthma.Objective: To study the role and inheritance of MMR9 in the bronchial asthma pathogenesis in children.Characteristics of children and research methods. The authors carried out the prospective study of 54 children with bronchial asthma and 56 healthy children with the determination of the MMP-9 level in blood serum, as well as the polymorphic variant 8202A>G of MMP9 gene.Results. Children with bronchial asthma had significantly higher content of MMP9 in the blood serum (431.76 [306.15; 612.93] ng/ml), as compared to the control group (276.05 [160.33; 397.02] ng/ml). When studying polymorphism 8202A>G of MMP9 gene in the examined patients it was found that the children with bronchial asthma had the G allele a little more often (57.5%) than A allele (42.5%). Heterozygous carriers of the MMP9 gene polymorphic variant predominate both among the patients with bronchial asthma and in the control group. When comparing the frequency of genotypes and alleles in the group of children with bronchial asthma and control group the authors revealed no statistically significant differences.Conclusion. The disease mechanism significantly depends upon the MMR9 concentration in the serum of patients with bronchial asthma and the peculiarities of this enzyme inheritance.

Abstract Aim and Background Asthma is an inflammatory disease affecting the airways of the lungs being characterized by reversible airflow obstruction and bronchospasm. Environmental and genetic factors play a role in the pathogenesis of the disease; these factors are controlled by epigenetic mechanisms. There is a demand of clinical biomarkers for diagnosis of asthma and monitoring the response to therapy. In this study, we aimed to evaluate the role of lnc-MEG3 expression and its downstream effector in the pathogenesis of bronchial asthma disease. Methods Based on bioinformatics analysis using online databases, the current work has been designed to study the expression status of lnc-MEG3 and GDF15 mRNA in serum and sputum of asthmatic children aiming to find its clinical significance. This study was conducted on 30 children, 15 children newly diagnosed with bronchial asthma as patient group (A) and 15 age and sex matched healthy children as control group (B). Quantitative PCR was carried out to evaluate the expression pattern of selected biomarkers in serum and sputum of asthmatic children. Results The expression of circulating lnc-MEG3 was highly significantly up-regulated in asthmatic children than in control group (p ≤ 0.01), while the expression of circulating GDF15 mRNA was highly significantly down-regulated in asthmatic children than in control group (p ≤ 0.01). The findings showed a negative significant correlation between both investigated biomarkers. Conclusion This study supports the role of lnc-MEG3 and GDF15 protein as potential biomarkers in diagnosis of bronchial asthma in children.

ARI occurs mostly in children under the age of five because their endurance is not strong in dealing with ARI. ARI results in deaths of around 15%-20% per year at the age of under-five in developing countries. The purpose of this study was to determine and analyze the role of mothers in improving the immune system of children against ARI. The research method used in this study was qualitative descriptive with a purposive sampling sample. Respondents and samples of this study were five mothers who had children with a history of ARI and currently suffering from the disease in Batu Gajah, Ambon City. The results of the study found 4 categories, namely providing nutrition to children to meet their needs so that their immune systems are maintained, clean environment, mother's role in preventing children with ARI, and mother's role to preserve and maintain the health of their children. The findings indicated that in terms of coping or improving the immune system of a child to avoid ARI, it is necessary to have role the of mothers in providing nutrition so that the immune system is boosted, besides that the mother can prevent and protect her child from various diseases, especially ARI.
