Основу работы составил ретроспективный анализ течения внебольничной пневмонии (ВП) у детей при COVID-19.</p><p>Цель работы — определить особенности течения ВП до и во время пандемии COVID-19 среди детей от рождения до 18 лет. </p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Проведён ретроспективный анализ медицинской документации 95 детей, находившихся на лечении в ДГКБ № 9 им. Г.Н. Сперанского до пандемии (октябрь–ноябрь 2019 г.; n = 45) и во время пандемии COVID-19 (апрель–май 2020 г. и октябрь–ноябрь 2020 г.; n = 50). Все полученные данные обработаны статистически.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что ВП до пандемии COVID-19 болели преимущественно подростки в возрасте 13–17 лет, во время пандемии чаще стали болеть дети младшего возраста (6–12 лет). С началом пандемии значительно изменилось течение ВП: типичными клиническими симптомами были лихорадка, кашель, одышка; локальные симптомы были более выражены у детей во время пандемии: чаще выявлялось ослабленное и жёсткое дыхание. Лейкоцитоз и ускоренное СОЭ преобладали у больных ВП до пандемии. При этом С-реактивный белок был более чувствительным маркером воспаления. С началом пандемии COVID-19 уменьшилось число атипичных пневмоний, что, возможно, связано с противоэпидемическими мерами, но частота пневмоний неустановленной этиологии увеличилась. Снижение сатурации кислорода было более частым проявлением при ВП во время пандемии. У детей до пандемии преобладала долевая пневмония, а у больных во время пандемии — полисегментарная.</p></sec><sec><title>Заключение</title><p>Заключение. Представленные авторами особенности проявлений ВП у детей до и во время пандемии COVID-19 позволяют оптимизировать их диагностику с использованием клинико-лабораторных признаков.</p></sec><sec><title>Участие авторов</title><p>Участие авторов:Савельева Е.И., Гадецкая С.Г. — концепция и дизайн исследования, сбор и обработка материала;Савельева Е.И. — статистическая обработка материала, написание текста;Корсунский А.А. — редактирование.Все соавторы — утверждение окончательного варианта статьи, ответственность за целостность всех частей статьи. </p></sec><sec><title>Финансирование</title><p>Финансирование.

The basis of the work was a retrospective analysis of the course of community-acquired pneumonia (CAP) in children with COVID-19. </p></sec><sec><title>Aim</title><p>Aim. To determine the features of the course of CAP before and during the COVID-19 pandemic in children from birth to 18 years.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A retrospective analysis of the medical records of ninety five children (n = 95) who were treated at the Speransky Children’s Hospital No. 9 before the pandemic (October–November 2019; n = 45) and during the COVID-19 pandemic (April–May 2020 and October–November 2020; n = 50). All the received data are processed statistically.</p></sec><sec><title>Results</title><p>Results. It was found that before the COVID-19 pandemic, mainly adolescents aged 13–17 years were ill, during the pandemic younger children (6–12 years old) became ill more often. With the onset of the pandemic, the course of CAP changed significantly: fever, cough, shortness of breath were typical clinical signs; local signs were more pronounced in children during the pandemic: weakened and hard breathing was more often detected. Leukocytosis and accelerated ESR prevailed in patients with CAP before the pandemic. At the same time, CRP was a more sensitive marker of inflammation. It was revealed that with the beginning of the COVID-19 pandemic, the number of atypical pneumonia decreased, which may be due to anti-epidemic measures, but the preva­lence of pneumonia of unknown etiology increased. Decreased oxygen saturation was a more frequent rule in CAP during the pandemic. Lobar pneumonia prevailed in children before the pandemic, and polysegmental pneumonia prevailed in patients during the pandemic. </p></sec><sec><title>Conclusion</title><p>Conclusion. The features presented by the authors of the manifestations of community-acquired pneumonia in children before and during the COVID-19 pandemic make it possible to optimize their diagnosis using clinical and laboratory signs.</p></sec><sec><title>Contribution</title><p>Contribution:Savelyeva E.I., Gadetskaya S.G. — research concept and design of the study, collection and processing of material;Savelyeva E.I. — statistical processing, text writing;Korsunskiy A.A. — editing.All co-authors — approval of the final version of the article, responsibility for the integrity of all parts of the article. </p></sec><sec><title>Acknowledgment</title><p>Acknowledgment.
