Данные литературы последних лет показывают, что дефицит витамина D (VD) играет определенную роль в патогенезе бронхиальной астмы (БА), влияя на регуляцию иммунных реакций и ремоделирование гладких мышц дыхательных путей. Эффективность включения VD в базисную терапию БА у детей является перспективной областью исследования.</p></sec><sec><title>   Цель</title><p>   Цель. Проанализировать эффективность фармакологической коррекции в отношении взаимосвязи сывороточной концентрации 25(ОН)D, периостина и TGF-β1 в зависимости от исходного уровня обеспеченности организма VD детей, страдающих БА.</p></sec><sec><title>   Материалы и методы</title><p>   Материалы и методы. В исследование были включены 80 детей в возрасте от 6 до 17 лет (средний возраст 12 ± 3,2 года). При исследовании уровня VD дети были распределены на 4 подгруппы: группа 1а — 40 детей с БА до коррекции VD, группа 1б — дети с БА после коррекции VD (n = 40), группа 2а включала 40 здоровых детей (группа сравнения) до коррекции, группа 2б — дети после коррекции VD-статуса (n = 40).</p></sec><sec><title>   Результаты</title><p>   Результаты. После приема VD у всех обследованных детей с БА увеличился уровень 25(ОН)D в сыворотке крови. Количество детей с дефицитом VD среди детей с БА снизилось с 72,5 % (n = 29) до 10,0 % (n = 29) (р = 0,000), а с недостаточностью VD выросло в 4,5 раза (р = 0,001), среди детей с нормальной обеспеченностью VD сывороточный уровень 25(ОН) D увеличился в 2,5 раза (р = 0,028). В группе сравнения у детей также отмечалась положительная динамика: после саплементации уменьшилось число детей с дефицитом VD в 2 раза, увеличилось число детей с недостаточностью VD на 18 %, с нормальной обеспеченностью на — 33 %, но статистически значимой разницы не было выявлено (р &gt; 0,05). Медиана периостина в группе детей, страдающих БА, находилась в диапазоне нормативных значений (норма 132,4–859,6 нг/мл), но после приема VD стала статистически значимо меньше, чем до приема VD (730,0 нг/мл [390,8; 1109,7] против 428,0 нг/мл [365,7; 582,5], р = 0,000). Показатели TGF-β1 не зависели от приема VD и находились в диапазоне нормативных значений. В ходе исследования нами установлена отрицательная корреляционная связь умеренной интенсивности между уровнем 25(ОН)D в сыворотке крови детей с БА и частотой обострений заболевания.</p></sec><sec><title>   Заключение</title><p>   Заключение. После проведения фармакологической коррекции VD-статуса отмечается возрастание уровня 25(ОН)D в сыворотке крови детей, страдающих БА, и особенно при легкой степени тяжести заболевания. Медиана периостина в группе детей, страдающих БА, после приема VD показатель статистически значимо уменьшился, а медиана TGF-β1 не зависела от VD-статуса и приема VD. Выявлено отрицательная корреляционная связь умеренной интенсивности между уровнем 25(ОН)D в сыворотке крови детей с БА и частотой обострений заболевания.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Introduction</title><p>   Introduction. Recent literature data show that vitamin D deficiency (VD) plays a role in the pathogenesis of bronchial asthma (BA), affecting the regulation of immune responses and remodeling of smooth muscles of the respiratory tract. The addition of VD to the basic therapy of BA in children is a promising area of research.</p></sec><sec><title>   Objective</title><p>   Objective. To analyze the relationship of serum concentrations of 25(OH)D, periostin and TGF-β1 in blood serum, depending on the level of VD provision in children with asthma after pharmacological correction.</p></sec><sec><title>   Materials and methods</title><p>   Materials and methods. The study included 80 children aged 6 to 17 years (mean age 12 ± 3.2 years). When analyzing the results of VD-complementation, the children were divided into 4 subgroups: group 1a — 40 children with asthma before VD correction, group 1b — children with asthma after VD correction (n = 40), group 2a included 40 healthy children (comparison group) before correction, group 2b included children after correction of VD status (n = 40).</p></sec><sec><title>   Results</title><p>   Results. After taking VD, the level of 25(OH) increased in all examined children with asthma in the blood serum. The number of children with VD deficiency in children with asthma decreased from 72.5 % (n = 29) to 10.0 % (n = 29) (p = 0.000), and with VD deficiency increased 4.5 times (p = 0.001), among children with normal VD provision, the serum level was 25(OH)D increased 2.5 times (p = 0.028). In the comparison group, there was also a positive trend in children: after complementation, the number of children with VD deficiency decreased by 2 times, the number of children with VD deficiency increased by 18 %, and those with normal income by 33 %, but no statistically significant difference was found (p &gt; 0.05). The median periostin in the group of children suffering from bronchial asthma was within the range of normal values (normal 132.4–859.6 ng/ml), but after taking VD it became statistically significantly lower than before taking VD (730.0 ng/ml [390.8; 1109.7] versus 428.0 ng/ml [365.75; 582.5], p = 0.000). The parameters of TGF-β1 were independent of VD intake and were in the range of standard values. In the course of the study, we established a negative correlation of moderate intensity between the level of 25(OH)D in the blood serum of children with asthma and the frequency of exacerbations of the disease.</p></sec><sec><title>   Conclusion</title><p>   Conclusion. After pharmacological correction of the VD status, an increase in the level of 25 (OH) is noted in the blood serum of children suffering from asthma, and especially with mild severity of the disease. The median periostin in the group of children suffering from asthma decreased statistically significantly after taking VD, and the median TGF-β1 was independent of VD status and VD intake. A negative correlation of moderate intensity was revealed between the level of 25(OH)D in the blood serum of children with asthma and the frequency of exacerbations of the disease.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>бронхиальная астма</kwd><kwd>витамин D</kwd><kwd>периостин</kwd><kwd>трансформирующий фактор роста β1</kwd><kwd>дети</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bronchial asthma</kwd><kwd>vitamin D</kwd><kwd>periostin</kwd><kwd>transforming growth factor β1</kwd><kwd>children</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Авторы заявляют об отсутствии спонсорской поддержки при проведении исследования</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The authors declare that no funding was received for this study</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бронхиальная астма : федеральные клинические рекомендации по диагностике и лечению. 2024. 193 с.</mixed-citation><mixed-citation xml:lang="en">Bronchial asthma: federal clinical guidelines for diagnosis and treatment. 2024. 193 p.
