Внебольничная пневмония (ВП) ассоциирована с развитием анемии и ее клинических проявлений: гипоксемии и гипоксии, что осложняет течение заболевания и приводит к развитию неблагоприятных исходов беременности. В исследованиях отсутствует сравнительная характеристика основных лабораторных признаков анемии у беременных с COVID-19-ассоциированной и бактериальной ВП, что имеет теоретическую и прикладную значимость.</p></sec><sec><title>Цель</title><p>Цель. Провести сравнительный анализ клинических показателей красной крови у беременных с COVID-19-ассоциированной и бактериальной ВП.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследовано 140 беременных в третьем триместре беременности, из них с ВП средней степени тяжести 100 участниц (основная группа) и с неосложненным течением беременности – 40 (группа сравнения). В основную группу вошли 47 беременных с бактериальной ВП и 53 участницы с COVID-19-ассоциированной ВП. Все беременные были сопоставимы по возрасту и сроку беременности. Проведены бактериологические исследования мокроты, выявление РНК SARSCov-2 в мазках из ротоглотки и носоглотки методом ПЦР, микроскопия мазков периферической крови, клинический анализ крови.</p></sec><sec><title>Результаты</title><p>Результаты. У беременных с COVID-19-ассоциированной ВП по сравнению с беременными с бактериальной ВП выявлен ряд различий по лабораторным параметрам, определяющим развитие анемии: снижено общее количество эритроцитов в 1,22 раза (p&lt;0,001) и содержание гемоглобина в 1,1 раза (p&lt;0,05), повышено процентное содержание эхиноцитов в 1,14 раза (p&lt;0,05) и дегенеративных форм эритроцитов в 1,16 раза (p&lt;0,05).</p></sec><sec><title>Заключение</title><p>Заключение. У беременных с COVID-19-ассоциированной ВП по сравнению с беременными с бактериальной ВП выявлены значимые изменения в количестве и морфологическом составе эритроцитов, содержании гемоглобина, свидетельствующие о высоком риске развития анемии и сопутствующий ей гипоксемии и гипоксии, что неблагоприятно сказывается на течении заболевания и приводит развитию осложнений беременности.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Community-acquired pneumonia (CAP) is associated with the development of anemia and its clinical manifestations: hypoxemia and hypoxia, which complicates the course of the disease and leads to the development of adverse pregnancy outcomes. The studies are lack of a comparative description of the main laboratory signs of anemia in pregnant women with COVID-19-associated and bacterial CAP, which has a theoretical and applied significance.</p></sec><sec><title>Aim</title><p>Aim. To carry out a comparative analysis of the clinical indicators of red blood in pregnant women with COVID- 19-associated and bacterial CAP.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 140 pregnant women were studied in the third trimester of pregnancy, of which 100 participants had CAP of moderate severity (main group) and with uncomplicated pregnancy – 40 (comparison group). The main group included 47 pregnant women with bacterial CAP and 53 participants with COVID-19-associated CAP. All pregnant women were comparable in age and duration of pregnancy. Bacteriological studies of sputum, detection of SARS-Cov-2 RNA in swabs from the oropharynx and nasopharynx by PCR, microscopy of peripheral blood smears, and a clinical blood test were performed.</p></sec><sec><title>Results</title><p>Results. In pregnant women with COVID-19-associated CAP, compared with pregnant women with bacterial CAP, a number of differences were revealed in laboratory parameters that determine the development of anemia: the total number of erythrocytes was reduced by 1.22 times (p&lt;0.001) and hemoglobin concentration by 1.1 times (p&lt;0.05), the percentage of echinocytes was increased by 1.14 times (p&lt;0.05) and degenerative forms of erythrocytes by 1.16 times (p&lt;0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. In pregnant women with COVID-19-associated CAP, compared with pregnant women with bacterial CAP, significant changes in the number and morphological composition of erythrocytes, hemoglobin concentration were revealed, indicating a high risk of developing anemia and concomitant hypoxemia and hypoxia, which adversely affects the course of the disease and leads to development of pregnancy complications.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>внебольничная пневмония</kwd><kwd>беременность</kwd><kwd>морфология эритроцитов</kwd><kwd>анемия</kwd><kwd>COVID-19</kwd></kwd-group><kwd-group xml:lang="en"><kwd>community-acquired pneumonia</kwd><kwd>pregnancy</kwd><kwd>erythrocyte morphology</kwd><kwd>anemia</kwd><kwd>COVID-19</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Niederman M.S.
