Связь обеспеченности детей витамином D с развитием и тяжестью течения атопического дерматита (АтД) однозначно не определена.</p><p>Цель исследования — сравнить концентрацию 25(ОН)D в сыворотке крови у детей с АтД и у здоровых сверстников с анализом ассоциации 25(ОН)D с тяжестью болезни и сенсибилизацией к аллергенам.</p></sec><sec><title>Методы</title><p>Методы. В исследование включали детей в возрасте 3–6 лет с АтД и здоровых сверстников. Обеспеченность витамином D оценивали по концентрации 25(ОН)D в сыворотке крови, которую определяли хемилюминесцентным иммуноанализом на микрочастицах. При концентрации 25(ОН)D 20 нг/мл устанавливали дефицит витамина D, 21–29 нг/мл — недостаточность. Сенсибилизацию к ингаляционным (клещи Dermatophagoides pteronyssinus, Dermatophagoides farinae, эпителий и перхоть кошки) и пищевым (белки коровьего молока и куриного яйца) аллергенам определяли по концентрации IgE, детектируемых методом иммунофлуоресценции.</p></sec><sec><title>Результаты</title><p>Результаты. Концентрация 25(ОН)D в сыворотке крови у детей с АтД (n = 106) была ниже, чем у здоровых сверстников (n = 40), медиана (межквартильный размах) — 26,5(19,0–35,3) и 32,4 (27,9–37,5) нг/мл соответственно (р = 0,012). При этом недостаточность/дефицит витамина D по концентрации 25(ОН)D были отмечены более чему половины (58%) больных АтД и у каждого третьего (37%) ребенка контрольной группы, отношение шансов — 3,5 (95% доверительный интервал — 1,6–7,5). Также установлено, что концентрация 25(ОН)D была ниже при среднетяжелом (в сравнении с легким) течении АтД, а также у детей, сенсибилизированных к ингаляционным и/или пищевым аллергенам.</p></sec><sec><title>Заключение</title><p>Заключение. У детей дошкольного возраста обеспеченность витамином D ассоциирована с АтД, степенью тяжести течения болезни и наличием сенсибилизации к ингаляционным и/или пищевым аллергенам.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. The association between the vitamin D provision for children and the atopic dermatitis (AD) development and severity is not clearly determined.</p></sec><sec><title>Objective</title><p>Objective. The aim of the study was to compare 25(OH)D serum concentration in children with AD and in healthy peers with association analysis of 25(OH)D with disease severity and allergen sensibilization.</p></sec><sec><title>Methods</title><p>Methods. The study included children aged from 3 to 6 years with AD and their healthy peers. Vitamin D provision was estimated via 25(OH)D serum concentration determined by chemiluminescent microparticle immunoassay. Vitamin D deficiency was established at 25(OH)D concentration  20 ng/ml, insufficiency — 21–29 ng/ml. Sensibilization to airborne (Dermatophagoides pteronyssinus, Dermatophagoides farinae, cat epithelium and dandruff) and food (cow's milk and chicken egg proteins) allergens was determined by IgE concentration revealed via immunofluorescence.</p></sec><sec><title>Results</title><p>Results. The 25(OH)D serum concentration in children with AD (n = 106) was lower than in their healthy peers (n = 40), median (interquartile range) — 26.5 ng/ml (19.0–35.3) and 32.4 ng/ml (27.9–37.5) respectively (p = 0.012). Meanwhile, vitamin D insufficiency/deficiency according to 25(OH)D concentration was revealed in more than half patients (58%) with AD and in every third child (37%) from control group (OR — 3.5, 95% CI — 1.6–7.5). It was also revealed that 25(OH)D concentration was lower in patients with moderate course of AD (in comparison to mild) as well as in children sensibilized to airborne and/or food allergens.</p></sec><sec><title>Conclusion</title><p>Conclusion. The vitamin D provision in preschool children is associated with AD, its severity and the presence of sensibilization to airborne and/or food allergens.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>атопический дерматит</kwd><kwd>витамин D</kwd><kwd>недостаточность</kwd><kwd>дефицит</kwd><kwd>25(ОН)D</kwd><kwd>дети</kwd><kwd>дошкольный возраст</kwd></kwd-group><kwd-group xml:lang="en"><kwd>atopic dermatitis</kwd><kwd>vitamin D</kwd><kwd>insufficiency</kwd><kwd>deficiency</kwd><kwd>25(ОН)D</kwd><kwd>children</kwd><kwd>preschool age</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование проведено на средства гранта ректора ФГБОУ ВО «Алтайский государственный медицинский университет» (приказ № 1048-пк от 19.12.19)</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was funded by rector’s grant (rector of Altai State Medical University) (decree № 1048-pk, date: 19.12.19)</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">Global, regional, and national incidence, prevalence, and years lived with disability for 354 diseases and injuries for 195 countries and territories, 1990–2017: a systematic analysis for the Global Burden of Disease Study 2017.
