Detoxification treatment in Gynecology using a modified molded sorbent.

Postpartum endometritis is a common complication of cesarean section, the progression of which often leads to the loss of the uterus and the patient's fertility. We evaluated a detoxification therapy for treating patients with postpartum endometritis using an intrauterine application of a modified molded sorbent containing polyvinylpyrrolidone. A retrospective, controlled study included 124 patients with postpartum endometritis. The study group, n = 63, was composed of puerperae with postpartum endometritis after cesarean section, receiving antibacterial therapy in combination with the intrauterine application of a molded modified sorbent containing polyvinylpyrrolidone (FSMP) for 24 h daily for 5 days. The control group, n = 61, was composed of puerperae with postpartum endometritis after cesarean section, receiving antibacterial treatment only. The uterine cavity was infected by coccal flora (Enterococcus faecalis (26.6%), Staphylococcus spp. (21.3%), E. faecium (14.3%), and Gram-negative Escherichia coli (9.6%). A combination of these microorganisms was present in 40.5% of crops. Antibiotic resistance was detected in 53.6%-68.3% of the cases. In the study group, we observed: a faster and higher decrease in neutrophils (p < 0.05); a lower uterine concentration of pro-inflammatory cytokines: interleukin-1 beta (IL-1ß) and tumor necrosis factor α (TNFα) - 4.0 and 3.2 times, respectively, compared with the control group (p < 0.05); and a significant decrease in the uterus volume and cavity (M-echo). Using a newly modified sorbent associated with antibiotic treatment in patients with postpartum endometritis, compared with antibiotics alone, we showed a sharp reduction of inflammatory parameters, residual microorganism growth, and faster uterine volume involution. Moreover, the frequency of hysterectomy decreased by 14.4 times.

Pregnancy and delivery in women with a high risk of infection in pregnancy.

BACKGROUND: Pregnant women with chronic genital and non-genital infections are at a high risk of infections complication during pregnancy and the postpartum period. Preterm birth is one of the leading causes of obstetric and neonatal complications and occurs in one in nine women. Forty per cent of preterm births are considered to be caused by the abnormal vaginal microbiome, and there is currently no consensus on the contribution of combined bacterial and viral infections. AIM: To assess the course of pregnancy and delivery in women with a high risk of chronic infections and the association with the presence of specific microorganisms in the genital microbiome. MATERIALS AND METHODS: We performed a prospective controlled observational study in 355 pregnant women with a high risk of chronic infections. The high risk was defined as presence acute or chronic genital or extragenital infections, reactivation of chronic infections/inflammatory diseases during current pregnancy and history of obstetric complications during previous pregnancies such as miscarriages, missed miscarriages, preterm deliveries, postpartum endometritis, and sepsis. RESULTS: In women with a high risk of chronic infections, pregnancy was associated with recurrent threatened pregnancy loss (49.8%), preterm premature rupture of fetal membranes (64.3%), followed by prolonged oligohydramnios. Almost in one in two women (47.9%), pregnancy resulted in the delivery of preterm, low-birth-weight neonates. One in three women (30%) experienced uterine hypotony and bleeding after vaginal and cesarean delivery. Almost a third of women (32.1%) developed inflammatory complications postpartum, and more than half of complications (54.4%) was observed in women giving birth prematurely. Vaginal and cervical cultures in women who experienced preterm birth were dominated by non-obligate pathogens. We observed persistence of the Herpesviridae family both in the cervical canal and uterine cavity, specifically the Epstein-Barr virus (17.2%; 95% CI: 10%, 26.8%). CONCLUSIONS: Pregnancies in women with a high risk of chronic infections were associated with high rates of recurrent threatened pregnancy loss, preterm rupture of membranes and preterm delivery.

Efficacy of distal haemostasis during caesarean delivery in women with placenta accreta spectrum disorders.

Pregnancies complicated by the placenta praevia are associated with an increased risk of massive obstetric bleeding and high rates of hysterectomy which are often caused by the placenta accreta. The aim of our study was to identify the risk factors for placenta praevia associated with PAS disorders and the efficacy of distal haemostasis during Cesarean delivery. METHODS: This was a cohort study carried out between 2014 and 2020 in 532 women with abnormal placental localization and attachment. The placental attachment spectrum (PAS) disorder diagnosis was confirmed during the surgery and by the histology results in 164/532 participants. Depending on the surgical approach during the Cesarean delivery, patients were divided into three groups. In Group 1 (n = 52), patients underwent bilateral uterine artery ligation. In Group 2 (n = 33), we used the combined compression haemostasis approach including the placement of tourniquets and insertion of an intrauterine balloon for controlled tamponade. In Group 3 (n = 79), we used the combination of surgical haemostasis with the controlled intrauterine tamponade using the vaginal and intrauterine Zhukovsky balloon. RESULTS: PAS was observed in 30.8% of the placenta praevia cases, and in 93.3% was associated with the presence of a uterine scar. Women with the placenta praevia and PAS had a significantly higher number of past deliveries (р = .001). According to the FIGO classification, 53.8% of women with placenta praevia observed during the Cesarean had РА1 and 46.2% PA2. With regards to the PAS disorders observed in 30.8% of patients, 38.4% had PAS3, 34.7% PAS4, 18.3% PAS5 and 8.5% PAS6. The histology analysis showed normal placental attachment in 42.9% of the total number of study participants, placenta accreta in 28.2%, placenta increta in 16.7%, and placenta percreta in 12.2%. In Group 1, we performed the resection of uterine wall with the attached portion of the placenta in 13.5% of women, in Group 2 in 30.3% women, and in Group 3 in 50.6% women. There was a significant 4.8-fold reduction in the number of hysterectomies in Group 3 versus Group 2 (р = .043) and a 4.4-fold reduction in Group 2 versus Group 1 (р = .003). In Group 2, the volume of blood loss was 1.3-fold lower and in Group 3 1.5-fold lower than in Group 1. Conclusion: The techniques of compression distal haemostasis evaluated in this study in women with PAS are efficacious in the reduction of adverse maternal outcomes and should be used more widely in clinical practice.

Placental blood flow and pregnancy outcomes in women with abnormal placental localization and absence of placental "migration".

AIM: We investigated the arcuate artery blood flow in the region of the abnormally localized placenta in women who had undergone insertion of an obstetric pessary and were receiving micronized progesterone. MATERIALS AND METHODS: The study included 120 pregnant women with high perinatal risks and abnormal placental localization. The patients were randomized to receive the Arabin's pessary and vaginal micronized progesterone (Group A, n = 60) or vaginal micronized progesterone only (Group B, n = 60). Randomization was carried based on the order of hospital admission: odd patient numbers were allocated to Group A and even numbers to Group B. Patients underwent a series of ultrasound scans to evaluate the placental migration and presence of abnormal placental attachment. Depending on the results of the scan, study participants were divided into the following groups: (1) patients without placental migration: A1 (n = 23) and B1 (n = 42); and (2) patients with placental migration: A2 (n = 37) and B2 (n = 18). Women in subgroups A1 and B1 were further divided into the subgroups based on the presence of abnormal placental attachment: A1x (n = 5) and B1x (n = 12) with abnormal placental attachment; and A1O (n = 18) and B1O (n = 30) without the abnormal placental attachment. CONCLUSION: In patients with abnormal placental attachment, the resistance of blood flow in the arcuate arteries was significantly higher than in those with normal placental attachment. A significant increase in the blood flow resistance occurred between 24 and 28 weeks of gestation. The combined use of the obstetric pessary and vaginal micronized progesterone in women with abnormal placental localization helped maintain the resistivity index at low levels and reduce the rate of abnormal placental attachment by 1.3-fold (OR 0.694 (95% CI: 0.21-2.29)).

Analysis of risk factors and predictors of pregnancy loss and strategies for the management of cervical insufficiency in pregnant women at a high risk of preterm birth.

AIM: To identify risk factors and predictors of pregnancy loss and to compare the efficacy of Arabin's pessary with cervical cerclage in women at a high risk of pregnancy loss. MATERIALS AND METHODS: This was a two-center retrospective case-control study that included 240 women at a high risk of preterm delivery. Group I (n = 161) included women who underwent insertion of the Arabin's pessary between 14 and 24 weeks of pregnancy. Group II (n = 79) included women who had undergone circular cervical cerclage during the current pregnancy. All women included in the study received micronized vaginal progesterone at the dose of 200 mg/day until and including 34 weeks of gestation. RESULTS: Threatened pregnancy loss defined as spotting or vaginal bleeding in the first trimester was diagnosed in 29.8% (48/161) of patients in Group I versus 37.9% in Group II (p = .448). Postpartum bleeding occurred in 8.1% (13/161) in women in Group I versus 22.8% in Group II (χ2 = 6.500; p = .011). Our study showed that cervical cerclage was most suitable for patients with history of obstetric complications, cervical length <15 mm, and large isthmic uterine fibroids. The use of the Arabin's pessary reduced the rate of preterm births by 1.7-fold. A cluster analysis demonstrated that predictors of preterm birth in women with a high risk of pregnancy loss included: threatened pregnancy loss associated with chorionic/placental abruption, cervical incompetence, uterine fibroid growth to a large size, history of multiple spontaneous pregnancy losses, cervical tears during past labor, and gestational diabetes diagnosed for the first time during the current pregnancy. CONCLUSIONS: Women with a high risk of pregnancy loss treated with Arabin's pessary or cerclage plus vaginal progesterone had a term delivery rate of 70.4% (169/240). The combined strategy of pregnancy management allowed to markedly reduce the number of preterm births.

[The diagnostic value of antibodies to annexin and B2-glycoprotein for verification of active course of herpesviral infections of pregnant women].

The article deals with results of analysis of hemostasiological and immunological alterations under reactivation of herpesviral infections during pregnancy. The formation of pathological thrombinemia, activation of intra-vascular blood clotting, increasing of factors resulted in damage of endothelium under active course of herpesviral infection and increasing risk of development of obstetric pathology are demonstrated. The antibodies to B2-glycoprotein class IgM and antibodies to annexin class IgM, IgG can be operated as diagnostic signs of activation of herpesviral infection during pregnancy.

[Clinical management of disorders hemostasis-related with obstetric complications].

BACKGROUND: The aim of the study was the reduction of adverse pregnancy outcomes in women with gestational and genetically determined changes in the hemostatic system. PATIENTS AND METHODS: The study group comprised 98 patients with obstetric complications on the background of changes in the parameters of coagulation screening. In 63 pregnant women, hemostatic disorders were not corrected, in 35 patients medical tactic defined clinical situation and the results of laboratory and instrumental studies of the hemostatic system. RESULTS: Hereditary thrombophilia detected in 85% of patients with obstetric complications. Carriage of the rare allele of MTHFR-677 2-fold increased risk of adverse pregnancy outcomes; heterozygous carriers of polymorphism PAI-1 - 1.5 times more. The prognostic parameters thrombelastographic (sensitivity 80%, specificity 82%) were higher than in laboratory tests. To determine the most predictive of adverse pregnancy outcome has a density of fibrin clot--the maximum amplitude. CONCLUSIONS: In women with obstetric complications associated with disturbances in the hemostatic system, medical diagnostic tactics using c thrombelastographic evaluates all stages of coagulation and fibrinolysis, allows you to select a reasonable pathogenetic anticoagulant therapy and reduce the number of adverse pregnancy outcomes.
