Introduction. Multiple sclerosis (MS) is a chronic disease of the central nervous system predominantly affecting women of reproductive age. It is known that there is a high incidence of low urinary tract infections in MS. However, information about microbiology of the genital tract in women with MS is extremely limited.Aim. To study the qualitative and quantitative composition of the vaginal microflora in patients with MS.Materials and methods. 19 patients with relapsing-remitting MS of the main group and 19 healthy women of the control group, the qualitative and quantitative composition of the microflora in the vaginal secretion was determined using the polymerase chain reaction method in real time (a set of reagents was used to study the biocenosis of the urogenital tract in women, Femoflor 16, DNA-Technology, Moscow), a gynecological smear from the vagina was performed. The neurological status was assessed using the EDSS scale and The questionnaire on pelvic organ function. The following statistical indicators were determined: frequency, spread, average and χ² test.Results. A status of normocenosis was observed in the majority of women with MS (14 subjects, 73.7%), Lactobacillus bacteria were found in 16 subjects (84.2%), and an increased number of facultative anaerobes was identified in 7 subjects (37.4%), there were no significant differences with the comparator group. Bacteriological examination findings from vaginal smears did not show any signs of inflammation in either group. A high incidence of vaginal infections in anamnesis was reported in women with neurogenic lower urinary tract dysfunction (16 subjects, 84.2%).Conclusion. Data on the state of the vaginal biocenosis of women with MS has been presented for the first time. It was found the preservation of normocenosis with a tendency to shift the balance towards dysbiotic processes in the vagina.

Aim. To identify immunological predictors of premature birth in women with isthmic-cervical insufficiency (ICN). Design. A prospective comparative cohort study. Materials and methods. The study included 58 pregnant women with ICN and 20 women without ICN. After completion of pregnancy, all women were divided into three groups: group 1 (main) — 23 patients with premature birth, group 2 (comparison) — 35 patients with timely delivery and group 3 (control) — 20 women with normal pregnancy without ICN. Indicators of innate immunity in cervical mucus were studied in all pregnant women. In patients with ICN, an immunological study was conducted at the time of this diagnosis. In participants without ICN, cervical mucus was collected 18–20 weeks after receiving the results of cervicometry. Results. In the main group, the average number of leukocytes and neutrophil extracellular traps (NET), lysosomal activity of neutrophils, levels of macrophage inflammation protein-1β (MIP1β) and BOX1 protein of the high mobility protein group (HMGB1) in cervical mucus were statistically significantly higher than in the comparison group and the control group. Using ROC analysis, the prognostic value of these markers in relation to premature birth in women with ICN was studied. It was found that the amount of NET > 18%, the levels of MIP1β > 13.5 pg/ml and HMGB1 > 10 ng/ml in cervical mucus can be considered as predictors of premature birth in patients with ICN. At the same time, the HMGB1 index has the highest sensitivity (78.3%) and specificity (80%) as a prognostic marker of premature birth in ICN. Conclusion. The proposed new approach to the prediction of premature birth in ICN is non-invasive and can be applied in the routine clinical practice of obstetricians and gynecologists. Keywords: isthmic-cervical insufficiency, premature birth, prognosis, innate immunity, HMGB1.

Introduction.The formation of isthmic-cervical insufficiency (ICI) in 80% is associated with intraamnial inflammation, this is the subject of discussion of new mechanisms of the pathogenesis of premature cervical remodeling. In this regard, it is of interest to study the relationship of ICS with intrauterine and cervicovaginal infections during pregnancy and their impact on the course and outcomes of pregnancy, which was the purpose of our study.Methods.A prospective cohort study included 100 pregnant women with ICI, taken by a continuous sample. All patients at the time of ICI manifestation underwent a comprehensive clinical and laboratory examination aimed at diagnosing cervicovaginal infections, according to e results of which the pregnant women were divided into 2 groups: the first group consisted of 72 women with ICI and cervicovaginal infections, the second group — 28 women with ICI and normocenosis of the vagina.Results.There were no significant differences between the compared groups in terms of the history of miscarriage, extragenital pathology and the frequency of complications of this pregnancy. Intrauterine infection during pregnancy in patients of group 1 was observed 4 times more often, being 55.6% (40) versus 14.3% (4) in group 2 (RR = 3.9, 95% CI = 1.5-9.9, p <0.001). Preterm birth was significantly more frequent in women of group 1, accounting for 62.5% (45), in group 2 — 28.6% (8). Perinatal mortality cases were observed only in group 1, amounting to 97‰ (7). In children from women in group 1, complications of the early neonatal period were more common, primarily due to prematurity. In addition, IUI in newborns was diagnosed 10 times more often in group 1, reaching 38.8% (26) of cases, compared with group 2 — 3.6% (1) (RR = 10.87, 95% CI = 1.55–76.22, p <0.001).Discussion.Perinatal outcomes in ICI associated with cervicovaginal infections are characterized by the presence of perinatal mortality, a higher incidence of preterm birth and IUI of the newborn than in women with ICI without cervicovaginal infection.

Introduction.The high frequency of inflammatory changin the placenta in isthmic-cervical insufficiency may be primarily associated with an ascending infection as a result of a violation of the barrier function of the cervix, however, premature remodeling of the cervix may also be secondary due to an already existing process. The study of the features of the spread of the infectious process and thnature of the inflammatory reaction in various structures of the placenta and fetal membranes can contribute to the understanding of pathogenetic mechanisms of preterm birth in isthmic-crvical insufficiency.Aim of the study— to evaluate the frequency and structure of inflammatory changes in the placenta in women with isthmic-cervical insufficiency.Materials and methods.A prospective cohort study was conduct, which included 154 pregnant women taken by the continuous sampling method. All patients were divided into two groups: group 1 consisted of 100 pregnant women with isthmic-cervical insufficiency, group 2 — pregnant women without isthmic-cervical insufficiency. All women after childbirth underwent a pathomorphological examination of the afterbirth.Results and discussion.In women with isthmic-cervical insufficiency, inflamatory changes in the placenta were detected in 71% (71) of cases, which was significantly more frequent compared to group 2 — 38.9% (21). Membranitis was significantly more frequent in isthmic-cervical insufficiency, amounting to 16% (16) versus 3.7% (2) comparison group (OR=4.32, 95% СI=1.03-18.09, p=0.023). Chorioamnionitis was 6 times more common in the afterbirth in women of group 1, accounting for 12% (12), versus 1.9% (1) in group 2 (OR=6.48, 95% CI=0.87-48.51, p=0.031). Involvement of the umbilical cord in the inflammatory process occurred only in pregnant women with isthmic-cervical insufficiency: funiculitis was combined with membranitis in 4% (4) of cases (p=0.137), the combination of funiculitis with choriomnionitis was detcted in 7% (7) of women p=0.047).Conclusion.The frequencof detection of inflammatory changes in the placenta in ICN was 71% (71). In the structure of inflammatory changes of the afterbirth in patients with ICN, the defeat of the fetal membranes prevails, which may indicate a predominatly ascending path of infection in this pathology. Damage membranes prevails, which may indicate a predominatly ascending path of infection in this pathology. Damage to the umbilical cord in ICN can occur both wth total inflammation of all structures of the placenta, and directly through the fetal membranes, without involving the chorion in the process.

Introduction. An important problem of modern obstetrics is the development and improvement of methods for predicting fetal growth retardation (FGR) and pregnancy outcomes in this pathology, since there are no proven effective treatments for FGR. Purpose of the study — to develop prediction criteria for newborn hypotrophy and cumulative adverse perinatal outcome in pregnant women with FGR. Objective. To identify key predictive factors for adverse perinatal outcomes in pregnancy complicated by FGR. Material and methods. A case-control, cohort-based study was conducted that included 155 pregnant women with FGR, who were divided into two groups after delivery: Group 1 included 90 patients with neonatal hypotrophy and Group 2 included 65 patients without neonatal hypotrophy. A comprehensive analysis of clinical and anamnestic, laboratory and instrumental data, peculiarities of the course of pregnancy and perinatal outcomes was performed. FGR was determined on the basis of ultrasound fetometry. Results. Factors associated with neonatal hypotrophy and unfavorable perinatal outcome were: impaired blood flow in the uterine arteries and/or umbilical artery, early preeclampsia and scarcity of water. Protective factors were antibacterial therapy for intrauterine infection, administration of low-molecular-weight heparin in the first trimester, and acetylsalicylic acid starting from the 12th to 16th weeks of gestation. Conclusion. The most promising measures in the prevention of FGR and adverse perinatal outcomes in this pathology may be timely prescription of antithrombotic correction and treatment of genital infections.

Despite the availability of diagnostics and modern methods of treatment, preterm birth with cervical insufficiency occurs in 44-57% of cases, while early preterm birth reaches 38,8%. To date, there is no doubt about the connection of premature labor and intraamnial inflammation, the frequency of which in cervical insufficiency reaches 80%. Most researchers are unanimous in the opinion that the ascending route of infection in intraamnial infection is a priority. It has been proven that a decrease in the absolute and relative amount of Lactobacillus spp., A change in the species composition of lactoflora or atypical vaginal colonization associated with premature birth and premature rupture of membranes. Conditionally pathogenic microorganisms of the vaginal biotope with an insufficient number of lactobacilli are capable of producing various proteases that destroy collagen, constituting the basis of connective tissue and determining the elasticity of the membranes, which allows us to consider cervicovaginal infections as one of the mechanisms of premature remodeling of the cervix and rupture of membranes. In that way, it is relevant to study the frequency and structure of genital infection in cervical insufficiency. The analysis of medical literature data, presented in the electronic libraries Elibrary and Pubmed for the last 10 years, devoted to the study of genital infection in cervical insufficiency. The issue of the relationship of cervicovaginal infections with premature remodeling of the cervix of the uterus was discussed, as well as studies on the role of intrauterine infection in the genesis of preterm labor. The results of scientific studies are presented, indicating both the direct influence of cervical incompetence on the risk of intraamnial infection and the root cause of genital infection in the pathogenesis of cervical insufficiency. Convincing data are given that timely diagnosis and treatment of violations of the vaginal biocenosis is one of the significant links in the prevention of premature birth. It is necessary to further study the pathogenetic relationship of cervicovaginal infections and cervical insufficiency.

The study aims to compare the frequency and forms of cervicovaginal infections in women with spontaneous extremely preterm labor that began with the development of regular labor or premature rupture of the fetal membrane. Material and methods. A retrospective comparative analysis of 10 201 births in the Regional Perinatal Center of Chelyabinsk for the period 2017–2018 is conducted. The frequency and form of cervicovaginal infections in women with extremely premature births that began with regular labor or premature rupture of the fetal membrane are compared. Results. Cervical and vaginal infections are diagnosed in all women with spontaneous extremely preterm birth. At the same time, in the group where childbirth began with the development of labor, inflammatory diseases of the lower reproductive tract in the form of vaginitis and cervicitis were statistically more frequent, while dysbiotic processes were statistically more often detected in the group with premature rupture of the fetal membrane.

It is known that iron deficiency is a negative factor for the onset of pregnancy. It aggravates its course, increasing the risk of preeclampsia, placental insufficiency, uterine inertia, premature birth, bleeding and hypogalactia. This condition increases the risk of unfavorable outcomes, iron deficiency anemia and cognitive delay in a child. Raising the awareness of women of reproductive age and the clinical suspicion of physicians regarding the iron deficiency anemia and latent iron deficiency can facilitate timely visit a doctor. At the expert council “Relevant issues of iron deficiency in the Russian Federation” held in June 2020, aspects of the epidemiology, diagnosis and treatment of this condition were discussed, and promising directions for improving the situation were proposed.

Введение: Задержка роста плода (ЗРП) занимает второе место в структуре причин перинатальной смертности, а ее наличие имеет длительное неблагоприятное влияние на здоровье ребенка. Оценка степени активации системы гемостаза при ЗРП в сопоставлении с клиническими исходами имеет важное значение в понимании патогенеза, улучшении прогнозирования и профилактики этого патологического состояния. Цель исследования: оценить состояние гемостаза у беременных с ЗРП в сравнении с женщинами с физиологическим течением беременности. Материалы и методы: Тип исследования: поперечный срез на базе когортного. В исследование включено 52 беременных. Основная группа — 32 пациентки с ЗРП, выявленной при ультразвуковой фетометрии; контрольная группа — 20 практически здоровых женщин без отягощенного акушерско-гинекологического анамнеза, с физиологически протекавшей беременностью, завершившейся неосложненными родами. Оценку состояния системы гемостаза проводили на сроке 24-32 нед гестации. Результаты: Среди факторов тромботического риска у беременных с ЗРП чаще выявлялось табакокурение во время беременности. Наличие ЗРП было значимо связано с маловодием, генитальной и внутриматочной инфекцией, преэклампсией, нарушениями маточно-плацентарно-плодового кровотока. У женщин с ЗРП обнаружен более высокий уровень фибриногена, а также повышение скорости роста сгустка, больший размер сгустка, более частое формирование спонтанных сгустков в сравнении с контрольной группой. Заключение: У беременных с ЗРП имеется протромботическая готовность плазмы, что может служить основанием для дальнейшей разработки антитромботической коррекции с целью улучшения перинатальных исходов. Background: Fetal growth retardation (FGR) is the second leading cause of perinatal mortality, has a long-term adverse effect on child health. Assessment of hemostasis activation in FGR in comparison with clinical outcomes is important for understanding pathogenesis, improving the prognosis and prevention of this pathological state. Objectives: to assess hemostasis state in pregnant women with FGR compared to women with physiological pregnancy. Patients/Methods: Type of study: crosssectional based on cohort. The study included 52 pregnant women. The main group consisted of 32 patients with FGR diagnosed by ultrasound fetometry; the control group consisted of 20 practically healthy women without burdened obstetric-gynecological history, with physiological pregnancy that ended in uncomplicated childbirth. Hemostasis assessment was carried out at 24-32 weeks of gestation. Results: Smoking during pregnancy as a factor of thrombotic risk was more common in pregnant women with FGR. FGR was significantly associated with oligohydramnios, genital and intrauterine infection, preeclampsia, and placental insufficiency. Women with FGR showed a higher level of fibrinogen, as well as an increased rate of clot growth, clot larger size, and more frequent formation of spontaneous clots in comparison with the control group. Conclusions: Pregnant women with FGR are characterized by prothrombotic state that may be the basis for further development of antithrombotic correction for improving perinatal outcomes.
