Retrospectively, taking into account the fact of NCI disease and the exclusion of severe somatic and obstetric comorbidities, 2 groups were formed. Group 1 (n=32) included pregnant women with FGR, without a history of NCI. Group 2 (n=41) included pregnant women with FGR who recovered from NCI by the end of the second and third trimesters. Thirty healthy pregnant women served as the controls. In addition to ultrasound assessment of the fetal placental unit, patients underwent testing for markers of inflammation, endothelial hemostasis dysfunction, decidualization, placental angiogenesis, and pathological insulin resistance.</italic></p> <p><bold><italic>Results:</italic></bold><italic> Pregnant women with a history of NCI had a higher incidence of FGR (1.3 times; OR 2.41 [95% CI 1.12–5.17]), more severe forms of FGR (2 times; OR 3.27 [95% CI 1.22–8.76]), more severe fetal-placental blood flow abnormalities (3.5-fold; OR 11.07 [95% CI 3.68-33.27]), and oligohydramnios (4.5-fold; OR 8.94 [95% CI 3.65–30.17]). The impact of NCI on the formation of placental insufficiency was expressed by an increase in systemic changes (thrombopoiesis, apoptosis), modulation of local processes (decidualization, placental angiogenesis), and the development of pathological insulin resistance and hyperinsulinemia, an immunopathological process of endotheliocytes. The identification of the most informative markers of FGR due to NCI allowed the development of a predictive index.</italic></p> <p><bold><italic>Conclusion:</italic></bold><italic> An in-depth study of the impact of NCI on the formation of FGR has important scientific and practical implications for the optimization of FGR prediction, which may help identify appropriate patient management strategies for high-risk pregnant women.</italic></p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Цель:</italic></bold><italic> Оценить лабораторно-инструментальные характеристики формирования задержки роста плода (ЗРП) вследствие новой коронавирусной инфекции (НКИ) для выделения патогенетически обоснованных информативных предиктивных маркеров.</italic></p> <p><bold><italic>Материалы и методы: </italic></bold><italic>В период эпидемической активности дельта-штамма НКИ проведено обследование 140 беременных группы высокого риска развития ЗРП в сроки 18–21 недель и 26–34 недель гестации. Ретроспективно, с учетом факта заболевания НКИ и исключения тяжелой соматической и акушерской патологии, были выделены 2 группы: 1-я – 32 беременные с ЗРП без НКИ, 2-я – 41 беременная с ЗРП, переболевшие НКИ в конце II и III триместрах. Контролем служили 30 здоровых беременных женщин. Дополнительно к ультразвуковой оценке фето-плацентарного комплекса исследовались маркеры воспаления, эндотелиально-гемостазиологической дисфункции, децидуализации, плацентарного ангиогенеза, патологической инсулинорезистентности.</italic></p> <p><bold><italic>Результаты: </italic></bold><italic>Доказано, что у беременных на фоне НКИ диагностируются более высокая частота ЗРП (в 1,3 раза; ОШ 2,41 [95% ДИ 1,12–5,17]), более тяжелые формы ЗРП (в 2 раза; ОШ 3,27 [95% ДИ 1,22–8,76]) с нарушением фето-плацентарных кровотоков более тяжелой степени (в 3,5 раза; ОШ 11,07 [95% ДИ 3,68–33,27]) и выявлением маловодия (в 4,5 раза; ОШ 8,94 [95% ДИ 3,65–30,17]). Влияние НКИ на формирование плацентарной недостаточности выражалось в нарастании системных изменений (тромбовоспаления, апоптоза), модуляции местных процессов (децидуализации, плацентарного ангиогенеза), а также развитии патологических инсулинорезистентности и гиперинсулинемии, иммунопатологического процесса к эндотелиоцитам. Выделение наиболее информативных маркеров ЗРП вследствие НКИ позволило предложить предикторный индекс.</italic></p> <p><bold><italic>Заключение:</italic></bold><italic> Углубленное изучение влияния НКИ на формирование ЗРП имеет важное научно-практическое значение для оптимизации предикции ЗРП, что определяет перспективу стратегии приоритетных направлений врачебной тактики ведения беременных высокого риска.</italic></p></trans-abstract><kwd-group xml:lang="en"><kwd>novel coronavirus infection (SARS-CoV-2)</kwd><kwd>fetal growth restriction</kwd><kwd>pregnancy</kwd><kwd>placental insufficiency</kwd><kwd>pathogenesis</kwd><kwd>insulin resistance</kwd><kwd>prognosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>новая коронавирусная инфекция (SARS-CoV-2)</kwd><kwd>задержка роста плода</kwd><kwd>беременность</kwd><kwd>плацентарная недостаточность</kwd><kwd>патогенез</kwd><kwd>инсулинорезистентность</kwd><kwd>прогнозирование</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Nikiforov V.V., Suranova T.G., Chernobrovkina T.Ya., Yankovskaya Ya.D., Burova SV.
