Materials and methods. The study included 1690 pregnant women, 107 of whom had IgG antibodies to HCV; in addition, 68 women (63.5 %) were diagnosed with chronic hepatitis C and had a positive test for HCV RNA. The diagnosis of CHC was confirmed by determining serum total anti-HCV IgG antibodies using an enzyme immunoassay. The qualitative and quantitative determination of HCV RNA in the blood was performed by polymerase chain reaction. The virus replicative activity was qualitatively assessed by the viral load: low - the level of HCV RNA was up to 103 lU/ml, moderate - from 103 to 106 lU/ml, and high - above 106 lU/ml. To quantify the results, we used the positivity index, i.e, the ratio of the serum optical density to the critical optical density (cut-off) in each test. Results. In the early stages of pregnancy, signs of severe immune-mediated hepatocyte injury persisted. In the II and Ill trimesters, there was an unusual discrepancy between the severity of viral load and the degree of hepatocyte injury as the course of CHC remained usual. Another evidence of the liver involvement in this immune-pathological mechanism was an 87 % decrease in alanine aminotransferase activity with an increase in the viral load in patients with CHC in the Ill trimester of pregnancy. Conclusion. Suppression of anti-HCV humoral immunity, but not cellular immunity, begins from early stages of pregnancy and is accompanied by a significant increase in hepatocyte lesions without an increase in the severity of the inflammatory process.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования: анализ нарушений соотношения уровней вирусной нагрузки при гепатите С (HCV) с изменениями иммунологической реактивности и последующими иммунопатологическими поражениями печени в динамике беременности у женщин с хроническим гепатитом С (ХГС). Материалы и методы. Обследовано 1690 беременных, у 107 из которых были выявлены IgG антитела к HCV; HCV РНК положительные с хроническим течением вирусного гепатита С составляли 63,5 % (68 женщин). Диагноз ХГС подтверждали определением в сыворотке суммарных анти- HCV IgG антител методом иммуноферментного анализа. Качественное и количественное определение РНК HCV в крови проводили методом полимеразной цепной реакции. Выраженность репликативной активности вируса условно оценивали в зависимости от вирусной нагрузки: низкая - при уровне HCV РНК до 103 МЕ/мл, умеренная - от 103 до 106 МЕ/мл и высокая - более 106 МЕ/мл. Для количественной оценки результатов использовали величину индекса позитивности: отношение оптической плотности исследуемого образца сыворотки к величине критической оптической плотности (cut-off) в каждом отдельном исследовании. Результаты. На ранних сроках беременности сохранялись признаки выраженного иммуноопосредованного поражения гепатоцитов. Во II и III триместрах беременности отмечено необычное для стандартного течения ХГС расхождение показателей выраженности вирусной нагрузки и степени поражения гепатоцитов. В качестве подтверждения механизмов иммунопатологической природы поражения печени, у больных с ХГС в III триместре беременности обнаруживается снижение активности аланинаминотран-сферазы до 87 % на фоне увеличения вирусной нагрузки. Заключение. Подавление анти-HCV гуморального иммунитета в отличие от клеточного наблюдается с ранних стадий беременности и сопровождается значительным увеличением инфицированности гепатоцитов без нарастания выраженности воспалительного процесса.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гепатит С</kwd><kwd>иммунная система</kwd><kwd>беременность</kwd><kwd>вирусная нагрузка</kwd><kwd>антитела</kwd><kwd>гуморальный иммунитет</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hepatitis C</kwd><kwd>immune system</kwd><kwd>pregnancy</kwd><kwd>viral load</kwd><kwd>antibodies</kwd><kwd>humoral immunity</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">Соринсон С.Н.
