В исследование включены 55 ЦМВ-серопозитивных беременных на сроке 8–11 нед в возрасте (24,7 ± 0,18) года: 20 с обострением цитомегаловирусной инфекции и 35 с латентным течением заболевания. Группу контроля составили 20 ЦМВ-серонегативных беременных, сопоставимые по возрасту и сроку беременности с группой беременных с ЦМВ инфекцией. Исследовали содержание линолевой кислоты, супероксиддисмутазы, глутатионпероксидазы и метгемоглобина в эритроцитах крови спектрофотометрическим методом. Глутатион в эритроцитах крови определяли гистохимическим методом, общее количество гемоглобина – на автоматическом гематологическом анализаторе, пероксид водорода в сыворотке крови – иммуноферментным методом.</p></sec><sec><title>Результаты</title><p>Результаты. При цитомегаловирусной инфекции отмечается повышение показателей экзогенного пероксида водорода и линолевой кислоты в эритроцитах крови беременных. Они в период обострения заболевания в первом триместре беременности вызывают окислительную модификацию и снижение уровня не только супероксиддисмутазы, глутатионпероксидазы и глутатиона, участвующих в процессах редокс-регулирования тиол-дисульфидного обмена эритроцитов, но и гемоглобина с образованием высокого количества метгемоглобина, способствуя снижению кислородного метаболизма и развитию гемической гипоксии. При латентном течении заболевания окислительное повреждение гемоглобина в эритроцитах крови беременных нивелируется увеличением активности редокс-ферментов, что поддерживает кислородный гомеостаз на необходимом для развития беременности уровне. </p></sec></abstract><trans-abstract xml:lang="en"><p>The goal is to study the mechanisms of linoleic acid-dependent oxidative damage to hemoglobin in blood erythrocytes of pregnant women with cytomegalovirus (CMV) infection during the first trimester.</p><sec><title>Materials and methods</title><p>Materials and methods. The study included 55 CMV-seropositive pregnant women at 8–11 weeks pregnant, aged 24,7 ± 0,18 years. 20 women had exacerbated cytomegalovirus infection and in 35 women a latent course of the disease was observed. The control group consisted of 20 CMV-seronegative pregnant women, comparable in age and gestational age with the group of pregnant women with cytomegalovirus infection. The levels of linoleic acid, superoxide dismutase, glutathione peroxidase and methemoglobin in the blood were studied by the spectrophotometry. Glutathione was determined by histochemical methods, the total amount of hemoglobin was measured using the automatic hematological analyzer, and hydrogen peroxide level was calculated by enzyme immunoassay.</p></sec><sec><title>Results</title><p>Results. In cytomegalovirus infection, an increase in the indices of exogenous hydrogen peroxide and linoleic acid in blood erythrocytes of pregnant women is observed. During the period of acute disease in the first trimester of pregnancy it causes oxidative modification and a decrease in the level of not only superoxide dismutase, glutathione peroxidase and glutathione, the processes involved in the redox regulation of thiol-disulfide exchange of erythrocytes, but also hemoglobin with formation of large amount of methemoglobin, which contributes to reduction of oxygen metabolism and development of hemic hypoxia. In the latent course of the disease, the oxidative damage to hemoglobin in the erythrocytes of pregnant women is mitigated by the increase in the activity of redox enzymes, which maintains oxygen homeostasis at the level necessary for the development of pregnancy. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>беременность</kwd><kwd>цитомегаловирусная инфекция</kwd><kwd>гемоглобин</kwd><kwd>линолевая кислота</kwd><kwd>окислительный стресс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pregnancy</kwd><kwd>cytomegalovirus infection</kwd><kwd>hemoglobin</kwd><kwd>linoleic acid</kwd><kwd>oxidative stress</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">Шестопалов А.В., Арутюнян А.В., Акуева М., Шестопалова М.А., Буштырева И.О.
