Atopic dermatitis (AD) is an inflammatory disease characterized by a chronic course with periods of remissions and exacerbations. IgE-independent atopic dermatitis is a medical and social problem of our time, since the disease manifests itself most often in childhood and is one of the most frequent forms of dermatoses among the pediatric population. The prevalence of atopic dermatitis among children is up to 20 %, among adults - 2-8 %. Recently, there has been a significant increase in atopic diseases worldwide. The aim: to study specific features of IgE-independent atopic dermatitis in children living in a metropolis. Materials and Methods. A prospective cohort study was conducted, which included 451 children aged 5 to 14 years with a diagnosis of AD who applied for outpatient care at the Moscow Scientific and Practical Center of Dermatovenereology and Cosmetology for the period 2020-2021. All parents (guardians) have given voluntary informed consent to the participation of children in the study and the publication of personal data. Examination of patients included general clinical methods, assessment of the SCORAD index and laboratory allergological examination (total and 73 specific IgE in blood serum with the most common food and aeroallergens). In 103 (22.8 %) children (57 (55.3 %) boys and 46 (44.7 %) girls), the results of the allergological analysis did not confirm concomitant allergic sensitization. Atopic dermatitis in these children was defined as IgE-independent. Results and Discussion. Predictors of the development of IgE-independent AD were hereditary predisposition [odds ratio (OR) 2.42; 95 % confidence interval (CI) 1.12-5.25], artificial feeding [OR 4.04; 95 % CI 1.46-11.20], comorbidities [OR 1.42; 95 % CI 0.57-3.52], late onset [OR 1.67; 95 % CI 0.81-3.41]. According to the SCORAD index, the majority of patients (75.7 %) had a moderate degree of AD and no seasonality. Features of skin rashes corresponded to the age periods of the course of AD: erythematous-squamous forms with lichenification foci prevailed. For the first time, the features of IgE-independent atopic dermatitis in children were shown. The role of risk factors for the development of IgE-independent atopic dermatitis in children has been shown for the first time. Conclusion. IgE-independent type of AD can be diagnosed in every fifth child with AD. The study of risk factors will allow predicting the development of this type of disease.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">Актуальность. Атопический дерматит является заболеванием воспалительного характера, для которого характерно хроническое течение с периодами ремиссий и обострений. IgE-независимый атопический дерматит является медико-социальной проблемой современности, так как заболевание проявляется чаще всего в детском возрасте и является одной из самых частых форм дерматозов среди детской популяции. Распространенность атопического дерматита среди детского населения составляет до 20 %, среди взрослого населения - 2-8 %. В последнее время отмечается значительный рост атопическими заболеваниями во всем мире. Цель исследования - изучить особенности IgE-независимого атопического дерматита (АтД) у детей в условиях мегаполиса. Материалы и методы . Проведено проспективное когортное исследование, в которое был включен 451 ребенок в возрасте от 5 лет до 14 лет с диагнозом АтД, обратившийся за амбулаторной помощью в ГБУЗ «Московский Центр дерматовенерологии и косметологии» за период 2020-2021 гг. Все родители (опекуны) дали добровольное информированное согласие на участие детей в исследовании и публикацию персональных данных. Обследование пациентов включало общеклинические методы, определение степени тяжести заболевания (индекс SCORAD) и лабораторное аллергологическое обследование (определение общего и 73 специфических IgE в сыворотке крови с наиболее распространенными пищевыми и аэроаллергенами). У 103 (22,8 %) детей (57 (55,3 %) мальчиков и 46 (44,7 %) девочек) результаты аллергологического исследования не подтвердили сопутствующую аллергическую сенсибилизацию. Атопический дерматит у данных детей был определен как IgE-независимый. Результаты и обсуждение. Предикторами развития IgE-независимого АтД были наследственная предрасположенность [отношение шансов (ОШ) 2,42; 95 % доверительный интервал (ДИ) 1,12-5,25], искусственное вскармливание [ОШ 4,04; 95 % ДИ 1,46-11,20], сопутствующая патология [ОШ 1,42; 95 % ДИ 0,57-3,52], поздний дебют [ОШ 1,67; 95 % ДИ 0,81-3,41]. По индексу SCORAD у большинства пациентов (75,7 %) определена средняя степень тяжести заболевания, отсутствие сезонности. Характер кожных высыпаний соответствовал возрастным периодам течения АтД с преобладанием эритематозно-сквамозных форм и наличием очагов лихенификации. Впервые были показаны особенности IgE-независимого атопического дерматита у детей. Впервые показана роль факторов риска развития IgE-независимого атопического дерматита у детей. Выводы. IgE-независимый тип АтД может диагностироваться у каждого пятого ребенка, обратившегося с клиникой Ат Д. Изучение факторов риска позволит спрогнозировать развитие IgE-независимого типа Ат Д.</p></trans-abstract><kwd-group xml:lang="en"><kwd>IgE-independent atopic dermatitis</kwd><kwd>children</kwd><kwd>clinical features</kwd><kwd>risk factors</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>IgE-независимый атопический дерматит</kwd><kwd>дети</kwd><kwd>клиническая картина</kwd><kwd>факторы риска</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Li H, Zhang Z, Zhang H, Guo Y, Yao Z.
