Разработать метод определения риска развития репродуктивной потери в I триместре беременности.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Cыворотка крови, цельная кровь, медицинская карта стационарного пациента (форма № 003/у-07), обменные карты (форма № 113/у-07) 94 беременных. У обследованных пациентов оценивалась концентрация интерлейкина-6 с помощью иммуноферментного анализа. Уровень лейкоцитов и моноцитов определялся в цельной крови общеклиническими рутинными методами на гематологическом анализаторе. Для проведения статистического анализа использовался пакет программ «Statistica», 10.0 и язык программирования «R», версии 4.1.</p></sec><sec><title>Результаты</title><p>Результаты. Разработанное уравнение логистической регрессии (чувствительность — 87,5 %, специфичность — 83,33 %, точность классификации — 86,17 %) путем определения линейного предиктора Z позволяет отнести беременную к группе высокого риска по развитию репродуктивной потери в I триместре (Z &gt; –0,4519).</p></sec><sec><title>Заключение</title><p>Заключение. Предложенный новый метод определения высокого риска развития репродуктивной потери в I триместре беременности позволяет проводить соответствующие лечебные мероприятия, способствуя сохранению репродуктивного здоровья женщин, улучшению фертильности и увеличению рождаемости.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective.

Blood serum, whole blood, medical records of an inpatient (form No. 003/-07), and exchange cards (form No. 113/-07) of 94 pregnant women. Interleukin-6 concentration was assessed in the examined patients by immune-enzyme analysis. The level of leukocytes and monocytes was determined in whole blood by general clinical routine methods on a hematology analyzer. Statistica 10.0 software package and “R” programming language, version 4.1, were used for statistical analysis.</p></sec><sec><title>Results</title><p>Results. The developed logistic regression equation (sensitivity, 87.5%; specificity, 83.33%; classification accuracy, 86.17%) by determining the linear predictor Z makes it possible to assign a pregnant woman to the high risk group for the development of reproductive loss in the 1st trimester (Z &gt; -0.4519).</p></sec><sec><title>Conclusion</title><p>Conclusion. The proposed new method for determining a high risk of developing reproductive loss in the 1st trimester of pregnancy makes it possible to carry out appropriate therapeutic measures to help preserve women’s reproductive health, improve fertility, and increase the birth rate.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>репродуктивная потеря</kwd><kwd>I триместр беременности</kwd><kwd>уравнение логистической регрессии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reproductive loss</kwd><kwd>I trimester of pregnancy</kwd><kwd>logistic regression equation</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">Волков ВГ, Чурсина ОВ.
