Уточнение характера дифференцировки В-лимфоцитов и факторов ее регуляции у женщин с угрожающим выкидышем и привычным невынашиванием беременности в анамнезе является актуальной проблемой, поскольку позволит выявить иммунные механизмы патогенеза данной патологии.</p><p>Цель: установить особенности дифференцировки В-лимфоцитов и факторов ее регуляции у женщин с привычным невынашиванием беременности в анамнезе и угрожающим самопроизвольным выкидышем на момент обследования.</p><p>Были обследованы беременные женщины в возрасте 18-40 лет в сроке гестации 5-12 недель. Основную группу составили 60 беременных женщин с угрожающим самопроизвольным выкидышем на момент обследования и привычным невынашиванием в анамнезе. В качестве контроля обследовано 35 беременных женщин с неосложненным течением беременности. Группу сравнения составили 25 первобеременных женщин с угрожающим самопроизвольным выкидышем на момент обследования. Материалом исследования служила периферическая венозная кровь. Методом проточной цитофлюориметрии определяли субпопуляции В-лимфоцитов СD19+, CD19+IgD+, CD20+IgM+, CD20+IgG+; СD19+СD20- СD38+, CD19+CD27- , CD19+CD27+. Сывороточный уровень BAFF и APRIL оценивался методом иммуноферментного анализа. В основной группе зарегистрировано увеличение в периферической крови доли В-клеток, CD20+IgM+ лимфоцитов и клеток памяти, наряду со снижением уровня наивных клеток и плазмоцитов. В группе сравнения зарегистрировано увеличение доли незрелых IgM+В-клеток, циркулирующих клеток памяти наряду со снижением наивных В-лимфоцитов.</p><p>В основной группе наблюдалось выраженное снижение сывороточного уровня BAFF по сравнению с группой контроля и сравнения. Анализ содержания APRIL показал выраженную тенденцию к снижению в группах с угрожающим выкидышем относительно здоровых беременных. Таким образом, угрожающий привычный и спорадический выкидыши были ассоциированы со сдвигом дифференцировки В-лимфоцитов в сторону незрелых форм и недостатком регулирующего влияния BAFF и APRIL, что выражается в нарушении В-клеточного гомеостаза и ослаблении гуморальных эффекторных механизмов на системном уровне.</p><p>Выявленные изменения могут свидетельствовать о едином механизме развития угрожающего самопроизвольного выкидыша, выраженность которого увеличивается при повторной потере беременности. Эти изменения могут приводить к усилению эффекторных цитотоксических механизмов и увеличению провоспалительных цитокинов, что может привести к развитию повреждающих реакций в фетоплацентарном комплексе, отражением чего может являться клиническая картина угрозы прерывания беременности. </p></abstract><trans-abstract xml:lang="en"><p>The important role of immune disorders in recurrent miscarriage has been proven. Clarification of the character of B-lymphocyte differentiation and its regulation factors in women with threatened miscarriage and recurrent miscarriage in history is an urgent problem, since it will reveal the immune mechanisms of the pathogenesis of this pathology. Purpose: to establish the features of B-lymphocyte differentiation and factors of its regulation in women with a history of recurrent miscarriage and threatening spontaneous miscarriage at the time of examination.</p><p>Were examined pregnant women aged 18-40 years at a gestation period of 5-12 weeks. The main group consisted of 60 pregnant women with a threatening spontaneous miscarriage at the time of examination and a history of recurrent miscarriage. As a control, 35 pregnant women with uncomplicated pregnancy were examined. The comparison group consisted of 25 primary pregnant women with threatened spontaneous miscarriage at the time of examination. The material for the study was peripheral venous blood. Subpopulations of B-lymphocytes CD19+, CD19+ IgD+, CD20+IgM+, CD20+IgG+ were determined by flow cytometry; CD19+CD20- CD38+, CD19+CD27- , CD19+CD27+. Serum levels of BAFF and APRIL were assessed by enzyme-linked immunosorbent assay.</p><p>In the main group, an increase in the proportion of B-cells, CD20+IgM+-lymphocytes and memory cells was recorded in the peripheral blood, along with a decrease in the level of naive cells and plasma cells. In the comparison group, an increase in the proportion of immature IgM+B-cells, circulating memory cells, along with a decrease in naive B-lymphocytes, was registered. in the main group there was a pronounced decrease in the serum BAFF level compared with the control and comparison groups. Analysis of the APRIL content showed a pronounced downward trend in groups with threatened miscarriage relative to healthy pregnant women. Thus, threatening habitual and sporadic miscarriages were associated with a shift in the differentiation of B-lymphocytes towards immature forms and a lack of regulatory influence of BAFF and APRIL, which is reflected in the disruption of B-cell homeostasis and weakening of humoral effector mechanisms at the systemic level. The revealed changes may indicate a single mechanism for the development of a threatening spontaneous miscarriage, the severity of which increases with repeated loss of pregnancy. These changes can lead to an increase in effector cytotoxic mechanisms and an increase in proinflammatory cytokines, which can lead to the development of damaging reactions in the fetoplacental complex, which can be reflected in the clinical picture of the threat of termination of pregnancy. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>беременность</kwd><kwd>угроза прерывания беременности</kwd><kwd>привычное невынашивание</kwd><kwd>В-лимфоциты</kwd><kwd>BAFF</kwd><kwd>APRIL</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pregnancy</kwd><kwd>threatened abortion</kwd><kwd>recurrent miscarriage</kwd><kwd>B-lymphocytes</kwd><kwd>BAFF</kwd><kwd>APRIL</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">Agnaeva A.O., Bespalova O.N., Sokolov D.I., Selkov S.A., Kogan I.Yu.
