В настоящее время установлено, что повышение экспрессии циклооксигеназы 2 в плаценте играет существенное значение в формировании плацентарных нарушений при патологическом течении беременности. Показано, что высокий уровень экспрессии циклооксигеназы 2 приводит к избыточному синтезу простагландинов, которые являются стимуляторами сократительной активности миометрия матки и запускают механизм прерывания беременности. Однако анализ современной литературы показал отсутствие данных, доказывающих вовлечение циклооксигеназы 2 в патогенез ранних выкидышей при цитомегаловирусной инфекции. Цель исследования. Установить патогенетическую роль циклооксигеназы 2 в невынашивании беременности ранних сроков при обострении цитомегаловирусной инфекции. Методы. В обследование были включены 86 женщин на сроке гестации 8–12 недель, из них 46 женщин с самопроизвольным абортом (О03) и обострением цитомегаловирусной инфекции (основная группа) и 40 – с медицинским абортом (О04) без цитомегаловирусной инфекции (контрольная группа). Материалом для исследования служили: сыворотка периферической крови, моча, гомогенат ворсинчатого хориона плацентарной ткани. Анализировали содержание циклооксигеназы 2, уровень антител IgM и IgG к цитомегаловирусу, низкоавидные антитела IgG к цитомегаловирусу (индекс авидности) методом иммуноферментного анализа; содержание арахидоновой кислоты – методом капиллярной газожидкостной хроматографии. Результаты. В ходе исследования у женщин основной группы установлено повышение концентрации арахидоновой кислоты на 59 % (p &lt; 0,001) и активности липолитического фермента циклооксигеназы 2 – на 58 % (p &lt; 0,001) в гомогенате ворсинчатого хориона плаценты. Заключение. При обострении цитомегаловирусной инфекции в гомогенате ворсинчатого хориона плаценты беременных с самопроизвольным абортом наблюдается увеличение содержания арахидоновой кислоты и уровня циклооксигеназы 2. Повышенный уровень циклооксигеназы 2 указывает на развитие осложнений беременности и может использоваться в качестве неспецифического маркера-предиктора угрозы прерывания беременности при обострении цитомегаловирусной инфекции.</p></abstract><trans-abstract xml:lang="en"><p>Background. Increased expression of cyclooxygenase 2 in the placenta plays a significant role in the formation of placental disorders in the pathological course of pregnancy. It was shown that a high level of expression of cyclooxygenase 2 leads to excessive synthesis of prostaglandins, which stimulate the contractile activity of the uterine myometrium and trigger the abortion mechanism. An analysis of modern literature has shown a lack of data proving the involvement of cyclooxygenase 2 in the pathogenesis of early miscarriages in cytomegalovirus infection. Objective. To establish the pathogenetic role of cyclooxygenase 2 in early pregnancy in the course of miscarriage during exacerbation of cytomegalovirus infection. Materials and methods. The study included 86 women with a gestational age of 8–12 weeks, of which 46 women with spontaneous abortion (O03) and exacerbation of cytomegalovirus infection (main group) and 40 women with medical abortion (O04) without cytomegalovirus infection (control group). The material for the study was peripheral blood serum, urine, homogenate of the villous chorion of the placental tissue. The content of cyclooxygenase 2, the level of IgM and IgG antibodies to cytomegalovirus, low-type IgG antibodies to cytomegalovirus (avidity index) were analyzed by enzyme-linked immunosorbent assay; the content of arachidonic acid – by capillary gas-liquid chromatography. Results. During the study, women of the main group found an increase in the concentration of arachidonic acid by 59 % (p &lt; 0.001) and the activity of the lipolytic enzyme cyclooxygenase 2 – by 58 % (p &lt; 0.001) in the placenta villous chorion homogenate. Conclusion. With an exacerbation of cytomegalovirus infection in the homogenate of the villous placenta chorion of pregnant women with spontaneous abortion, an increase in the content of arachidonic acid and the level of cyclooxygenase 2 is observed. An increased level of cyclooxygenase 2 indicates the development of pregnancy complications and can be used as a non-specific marker predictor of pregnancy termination during exacerbation of cytosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>циклооксигеназа 2</kwd><kwd>арахидоновая кислота</kwd><kwd>невынашивание беременности</kwd><kwd>цитомегаловирусная инфекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cyclooxygenase 2</kwd><kwd>arachidonic acid</kwd><kwd>miscarriage</kwd><kwd>cytomegalovirus infection</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовом обеспечении Министерства науки и высшего образования Российской Федерации.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Демина Т.Н., Воронова И.И.
