Высокая распространённость детской аллергопатологии определяет необходимость разработки современных подходов к диагностике и профилактике атопических процессов, идентификации чувствительных и специфических биомаркеров иммунорегуляции, в том числе генетических, с детальным анализом отдельных этиопатогенетических звеньев развития заболевания.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследовано детское население среднего школьного возраста Пермского края: 65 детей с аллергопатологией и 55 относительно здоровых детей. Маркеры гиперчувствительности исследовали с помощью иммуноферментного анализа. SNP-генотипирование проводили методом полимеразной цепной реакции в режиме реального времени.</p></sec><sec><title>Результаты</title><p>Результаты. У детей с проявлениями аллергии наблюдалось возрастание индекса аллергизации в 1,4 раза, эозинофилов крови — в 2,3 раза, концентрации общего IgE — в 12,6 раза относительно группы здоровых детей (р &lt; 0,001). Показаны значимые ассоциации с развитием аллергопатологии полиморфизмов кандидатных генов 836G*MMP9 (отношение шансов (ОШ) = 2,09; 95% доверительный интервал (ДИ) 1,10–3,99) и -174G*IL-6 (ОШ = 2,25; 95% ДИ 1,20–4,25). Сравнительный анализ комбинации аллелей иммунорегуляторных генов 836G*MMP9/-174G*IL-6 с альтернативными аллельными комбинациями показал её выраженную связь с риском развития аллергических заболеваний (относительный риск 2,08; 95% ДИ 1,27–3,41), активацией маркеров аллергического воспаления: общего IgE и эозинофилов крови (в среднем в 4,5 и 1,8 раза) для детей с аллергопатологией (p = 0,003–0,014).</p></sec><sec><title>Ограничения исследования</title><p>Ограничения исследования. Исследование ограничено объёмом обследованной выборки.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные данные указывают на риск формирования аллергопатологии в популяции детей с комбинацией аллелей кандидатных генов 836G*MMP9/-174G*IL-6, что позволяет рекомендовать использовать полиморфизмы кандидатных генов иммунорегуляции — 836A&gt;G гена MMP9 и -174G/C гена IL-6 в качестве перспективных маркеров ранней диагностики, профилактики и коррекции атопических заболеваний у детей.</p><p>Соблюдение этических стандартов. Исследование выполнено в соответствии с Хельсинкской декларацией Всемирной медицинской ассоциации (2013 г.) и одобрено Этическим комитетом ФБУН «Федеральный научный центр медико-профилактических технологий управления рисками здоровью населения» (протокол № 9 от 14.03.2023).

The high level of allergic diseases among the child population requires for research to develop modern approaches to the diagnosis and prevention of atopic processes with the detection of specific highly sensitive biomarkers of immunoregulation, including genetic ones, with a detailed analysis of individual etiopathogenetic links in the development of the disease.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The children’s population of secondary school age in the Perm region was examined: 65 children with allergic pathology and 55 relatively healthy children. Markers of hypersensitivity were studied using enzyme-linked immunosorbent assay. SNP genotyping was performed using real-time PCR.</p></sec><sec><title>Results</title><p>Results. Children with manifestations of allergy showed an increase in the allergization index by 1.4 times, in blood eosinophils – by 2.3 times, and total IgE concentration by 12.6 times relative to the group of healthy children (p &lt; 0.001). Significant associations with the development of allergic diseases of candidate genes polymorphisms 836G*MMP9 (OR = 2.09; 95% CI = 1.10–3.99) and -174G*IL-6 (OR = 2.25; 95% CI = 1.20–4.25) was revealed. A comparative analysis of the combination of alleles of candidate immunoregulatory genes 836G*MMP9/-174G*IL-6 with alternative allelic combinations showed its significant association with an increased risk of developing allergic pathology (RR = 2.08; 95% CI = 1.27–3.41), activation of allergic inflammation markers: total IgE and blood eosinophils (on average 4.5 and 1.8 times) for children with allergic pathology (p = 0.003–0.014).</p></sec><sec><title>Research limitations</title><p>Research limitations. The study is limited by the size of the sample examined.</p></sec><sec><title>Conclusion</title><p>Conclusion. The data obtained indicates to the risk of developing allergic pathology in children for the combination of candidate gene alleles 836G*MMP9/-174G*IL-6 (RR = 2.08; 95% CI = 1.27–3.41), so it should be recommended as a promising marker for early diagnosis, prevention and correction of atopic diseases in children.</p><p>Compliance with ethical standards. The study was carried out in accordance with the Declaration of Helsinki by the World Medical Association (revised in 2013) and approved by the Ethics Committee of the Federal Scientific Center for Medical and Preventive Health Risk Management Technologies (Protocol No. 9 of March 14, 2023).
