Introduction. Venous thromboembolism (VTE) is one of the lead causes for maternal mortality and morbidity during pregnancy in the majority of developed countries. The incidence rate of VTE per pregnancy-year increases during pregnancy and postpartum period about by 4-fold and at least 14-fold, respectively.Aim: to analyze and summarize current view on risk factors of thrombotic events during gestation and to discuss recent guidelines for the management of venous thromboembolic complications during pregnancy and postpartum, by taking into account a balance between risks and benefits of using anticoagulants.Materials and Methods. The literature search covering the last 10 years was carried out in the electronic scientific databases RSCI, PubMed/MEDLINE, and Embase. While formulating a search strategy for evidence-based information, the PICO method (P = Patient; I = Intervention; C = Comparison; O = Outcome) and the key terms “venous thromboembolism” and “pregnancy” were used.Results. Risk factors were found to include a personal history of VTE, verified inherited or acquired thrombophilia, a family history of VTE and general medical conditions, such as immobilization, overweight, varicose veins, some hematological diseases and autoimmune disorders. VTE is considered being potentially preventable upon prophylactic administration of anticoagulants, but no high confidence randomized clinical trials comparing diverse strategies of thromboprophylaxis in pregnant women have been proposed so far. Because heparins do not cross the placenta, weight-adjusted therapeutic-dose low molecular weight heparins (LMWH) represent the anticoagulant treatment of choice for VTE during pregnancy. Once- and twice-daily dosing regimens are acceptable. However, no evidence suggesting benefits for measurement of factor Xa activities and consecutive LMWH dose adjustments to improve clinical outcomes are available. In case of uncomplicated pregnancy-related VTE, no routine administration of vitamin K antagonists, direct thrombin or factor Xa inhibitors, fondaparinux, or danaparoid is recommended. Lactating women may switch from applying LMWH to warfarin. Anticoagulation therapy should be continued for 6 weeks postpartum with total duration lasting at least for 3 months.Conclusion. VTE is a challenging task in pregnant women expecting to apply a multi-faceted approach for its efficient solution by taking into account updated recommendations and personalized patient-oriented features.

: Venous thromboembolism (VTE), clinically presenting as deep-vein thrombosis (DVT) or pulmonary embolism (PE), constitutes a major global healthcare concern with severe complications, long-term morbidity and mortality. Although several clinical, genetic and acquired risk factors for VTE have been identified, the molecular pathophysiology and mechanisms of disease progression remain poorly understood. Anticoagulation has been the cornerstone of therapy for decades, but there still are uncertainties regarding primary and secondary VTE prevention, as well as optimal therapy duration. In this review we discuss the role of factor Xa in coagulation cascade and the different choices of anticoagulation therapy based on patients’ predisposing risk factors and risk of event recurrence. Further, we compare newer agents to traditional anticoagulation treatment, based on most recent studies and guidelines.

Background D-dimer increases during pregnancy and is problematic to use in the diagnosis of venous thromboembolism. Fibrin monomer represents an alternative biomarker for venous thromboembolism. However, to be useful in pregnancy, the fibrin monomer concentration should be stable throughout pregnancy and during postpartum. Methods To describe the course of fibrin monomer concentration during pregnancy and the postpartum period in healthy pregnant women and to compare their within-subject biological variation (CVI) with non-pregnant women. Blood samples were obtained every fourth week during pregnancy and three samples after delivery in 20 healthy women and every fourth week during a 40-week period in 19 healthy non-pregnant women. Fibrin monomer (STA Liatest FM, Stago) was analysed in duplicates for all samples. Concentrations of fibrin monomer in pregnant and non-pregnant women were compared and the CVI for fibrin monomer was calculated. Results The median fibrin monomer concentration in pregnant women was 6.2 mg/L (2.5 and 97.5 percentiles 3.7–10.8 mg/L) and in non-pregnant women 4.8 mg/L (3.6–8.2) ( P < 0.01). The fibrin monomer concentration was relatively stable during pregnancy, although a few unexplained high fibrin monomer concentrations were found during pregnancy/postpartum. Fibrin monomer CVI in pregnancy and postpartum was 20.6% (95% CI 18.3, 23.5) and in non-pregnant 16.1% (13.7, 18.9). Conclusions For clinical purposes, fibrin monomer concentration can be considered stable during pregnancy, although it is slightly higher than in non-pregnant women. Pregnant and non-pregnant women have the same CVI. The suitability of fibrin monomer in venous thromboembolism diagnosis in pregnant women should be validated in further studies.

AbstractThrombosis in pregnancy is a major cause of maternal and fetal morbidity and mortality. Risk stratification of venous thromboembolism (VTE) during pregnancy is complex. The hypercoagulability observed in pregnant women can reduce bleeding during childbirth, but may cause thrombosis especially in the presence of additional prothrombotic risk factors such as antiphospholipid antibodies or genetic thrombophilic defects. The availability of large datasets allows for the identification of additional independent risk factors, including assisted reproductive technologies (ARTs), endometriosis, and recurrent pregnancy loss. Data on the risk of VTE linked to COVID-19 in pregnant women are very limited, but suggest that infected pregnant women have an increased risk of VTE. Current guidelines on the prevention and treatment of VTE in pregnancy are based on available, albeit limited, data and mainly present expert opinion. Low-molecular-weight heparins (LMWHs) are the mainstay of anticoagulation to be employed during pregnancy. Administration of LMWH for VTE treatment in pregnancy should be based on the personalized approach, taking into account a weight-based adjusted scheme. During gestation, due to physiological changes, in women at high risk of VTE, monitoring of anti-Xa activity is performed to ensure adequate LMWH dosing. As for the treatment duration for pregnant women with acute VTE, guidelines suggest that anticoagulation should be continued for at least 6 weeks postpartum for a minimum total duration of therapy of 3 months.

SummaryWomen with a history of venous thromboembolism (VTE), thrombophilia or both may be at increased risk of thrombosis during pregnancy, but the optimal management strategy is not well defined in clinical guidelines because of limited trial data. A strategy of risk assessment and heparin prophylaxis was evaluated in pregnant women at increased risk of VTE. In a prospective trial (Efficacy of Thromboprophylaxis as an Intervention during Gravidity [EThIG]), 810 pregnant women were assigned to one of three management strategies according to pre-defined risk factors related to history of VTE and thrombophilic profile. Low-risk women (group I), received 50–100 IU dalteparin/ kg body weight/ day for 14 days postpartum, or earlier when additional risk factors occurred. Women at high (group II) or very high risk (group III) received dalteparin from enrolment until six weeks postpartum (50–100 IU and 100–200 IU/ kg/ day, respectively). Objectively confirmed, symptomatic VTE occurred in 5/810 women (0.6%; 95% confidence interval [CI], 0.2 to 1.5%) (group I, 0 of 225; II, 3/469; III, 2/116). The rate of serious bleeding was 3.0% (95 % CI, 1.9 to 4.4%); 1.1% (95 % CI, 0.5 to 2.2%) was possibly dalteparin-related. There was no evidence of heparin- induced thrombocytopenia, one case of osteoporosis, and rates of miscarriage and stillbirth were similar to previous, retrospective studies. Risk-stratified heparin prophylaxis was associated with a low incidence of symptomatic VTE and few clinically important adverse events. Antepartum heparin prophylaxis is, therefore, warranted in pregnant women with idiopathic thrombosis or symptomatic thrombophilia.

AbstractAlthough venous thromboembolism (VTE) is a leading cause of maternal mortality, there is a paucity of real-world clinical data on clinical presentation and management of VTE during pregnancy and postpartum period. Using data from the international RIETE (Registro Informatizado Enfermedad Trombo Embólica) registry, pregnant and postpartum women with VTE were identified. Baseline characteristics, risk factors, therapies, and outcomes were compared. From March 2001 to July 2019, 596 pregnant and 523 postpartum women had symptomatic, objectively confirmed VTE. Pregnant or postpartum women were less likely to have another risk factor for VTE (i.e., immobility, cancer, recent travel) than nonpregnant women aged < 50 years. The prevalence of thrombophilia was higher among pregnant and postpartum women compared with nonpregnant women (53.2% vs. 46%). Pulmonary embolism (PE) was less commonly diagnosed in pregnant versus postpartum women (27% vs. 42%). Pregnant women with PE were commonly treated with low molecular weight heparin (73% vs. 29%), and received more inferior vena cava filters (6.0% vs. 4.2%) compared with postpartum women. By 90 days, one pregnant and one postpartum woman died after PE, and one died after a deep venous thrombosis. The incidence of recurrent VTE was low. In this largest cohort of pregnant and postpartum women with confirmed VTE, we found that pregnant and postpartum women with VTE were unlikely to present with other risk factors for VTE. Adverse outcomes in our study were uncommon.

Background: Pregnancy-associated hemorrhagic stroke (HS), while rare, is a significant cause of maternal mortality. Prior studies have suggested that the pathophysiology of HS may differ in pregnant/postpartum women when compared with HS in other young adults. Methods: We conducted a single-center retrospective analysis of a prospectively collected stroke registry, for patients aged 18-45, admitted with HS of any type from 01/2008-03/2015. We reviewed charts for study variables, including patient characteristics, risk factors, stroke mechanisms, and outcomes. Good outcome was defined as modified Rankin score of 0-2 at time of discharge. We compared study variables between three groups: pregnant/postpartum women, non-pregnant/postpartum women, and men. Results: Of 219 young adults with HS during the study period, 93 (42%) were men and 126 (58%) were women, of whom 19 (15.1%) were pregnant/postpartum. Among men, 58 (62.4%) had ICH and 41 (33.3%) had SAH, 31 (75.6%) of which were aneurysmal. Among non-pregnant women, 49 (45.8%) had ICH and 61 (57%) had SAH, 53 (87%) of which were aneurysmal. Among pregnant/postpartum women, 10 had ICH (52.6%) and 11 (57.9%) had SAH, 1 of which was aneurysmal. Compared with men and with non-pregnant women, pregnant/postpartum women had fewer vascular risk factors, were more likely to have history of migraine, and were more likely to have the reversible cerebral vasoconstriction syndrome as stroke mechanism (11/19, 57.9% versus 0/93 men and 2/107 non-pregnant women, p=0.0001). While there were no deaths in the pregnant/postpartum group, there were no significant differences between groups in good outcome (Table). Conclusions: In our analysis, pregnancy-associated hemorrhages were uniquely non-aneurysmal and associated with fewer cerebrovascular risk factors than age-matched men and non-pregnant women, suggesting there is a pregnancy-specific pathophysiology for HS that requires special consideration.

Aim. To determine the risk factors for human papillomavirus of high carcinogenic risk (HPV HCR) and cervical diseases (CD) in pregnant women associated with the social status, reproductive and contraceptive behavior. Materials and methods. Design: open-label comparative non-interventional cohort study in parallel groups. The total number of patients 330 people, of whom 148 women were negative for HPV and 182 women were positive. They were divided into 4 groups depending on the presence or absence of CD. Methods: analysis of anamnesis data, general clinical, test Kvant-21 to determine HPV, cytological examination, extended colposcopy. Results. The most significant risk factors for HPV HRS infection were identified: history of mycoplasma infection (OR 5.9) and BV (OR 5.3), alcohol consumption (OR 4.0). A history of STIs (trichomoniasis and chlamydial infection), as well as more than 3 sexual partners (OR 2.7) were also significant. The most significant risk factors for CD in HPV-infected women were: age over 35 years (OR 3.8), a history of bacterial vaginosis (OR 3.0), and lack of regular screening (OR 2.4). The coitarche earlier than 16 years old (OR 2.2) also mattered. There were also found factors indicating a low risk of HPV infection the use of condoms (OR 0.3), and a low risk of CD was indicated by age under 25 years (OR 0.2) and regular screening (OR 0.3). Conclusion. HPV infection with HRS and the prevalence of CMC in pregnant women against the background of HPV infection is associated mainly with social risk factors, to a lesser extent with factors of reproductive and contraceptive behavior.

SummaryData on the long-term survival following venous thromboembolism (VTE) are rare,and the influence of thrombophilia has not been evaluated thus far. Our aim was to assess thrombophilia-parameters as predictors for long-term survival of patients with VTE. Overall, 1,905 outpatients (99 with antithrombin-, protein C or protein S deficiency, 517 with factor V Leiden, 381 with elevated factor VIII and 160 with elevated homocysteine levels, of these 202 had a combination and 961 had none of these risk factors) were included in the study between September 1, 1994 and December 31, 2007. Retrospective survival analysis showed that a total of 78 patients (4.1%) had died during the analysis period, among those four of definite or possible pulmonary embolism and four of bleeding. In multivariable analysis including age and sex an association with increased mortality was found for hyperhomocysteinemia (hazard ratio 2.0 [1.1.-3.5]) whereas this was not the case for all other investigated parameters. We conclude that the classical hereditary thrombophilia risk factors did not have an impact on the long-term survival of patients with a history of VTE. Thus our study supports the current concept that thrombophilia should not be a determinant for decision on long term anticoagulation. However, hyperhomocysteinaemia, known as a risk factor for recurrent VTE and arterial disease, might impact survival.

The objective: to study the features of pregnancy, childbirth, postpartum period, fetal status and newborns in patients with a history of chronic salpingo-оophoritis.Materials and methods. Conducted a retrospective study of 150 birth histories and neonatal development maps. All patients were divided into two groups. The main group includes 100 patients with chronic salpingo-оophoritis, for which they received anti-inflammatory treatment from 1 to 3 times before pregnancy. The control group included 50 pregnant women who did not suffer from chronic salpingo-оophoritis.Results. Our analysis of pregnancy, childbirth, fetal and neonatal status in women with chronic salpingo-оophoritis indicates that such patients have a complicated obstetric and gynecological and somatic history, which forms an unfavorable basic condition of organs and systems, imperfect adaptation to pregnancy, high risk of failure of adaptive reactions. The result is a violation of the formation and development of the mother-placenta-fetus system and, as a consequence, a high level of complications during pregnancy, childbirth and perinatal pathology.Conclusion. Patients suffering from chronic salpingo-oophoritis should be considered at high risk of possible complications during pregnancy and childbirth. This category of women needs quality preconception training and careful monitoring during pregnancy.

Abstract Context Early diagnosis and treatment of gestational diabetes (GDM) may reduce adverse obstetric and neonatal outcomes, especially in high-risk women. However, there is a lack of data for other outcomes. Objective We compared cardiometabolic and mental health outcomes in women with early (eGDM) and classical (cGDM) GDM. Methods This prospective cohort included 1185 women with cGDM and 76 women with eGDM. eGDM had GDM-risk factors (BMI &gt;30kg/m 2, family history of diabetes, history of GDM, ethnicity), were tested at &lt;20 weeks gestational age and diagnosed using ADA prediabetes criteria. Women underwent lifestyle adaptations. Obstetric, neonatal, mental, cardiometabolic outcomes were assessed during pregnancy and postpartum. Results eGDM had lower gestational weight gain than cGDM (10.7±6.2 vs 12.6±6.4, p=0.03), but needed more medical treatment (66% vs 42%, p&lt;0.001). They had similar rates of adverse maternal and neonatal outcomes, except for increased large-for-gestational-age infants (25% vs 15%, p=0.02). Mental health during pregnancy and postpartum did not differ between groups. eGDM had more atherogenic postpartum lipid profile than cGDM (p≤0.001). In eGDM, the postpartum prevalence of metabolic syndrome (MetS) was 1.8-times, prediabetes was 3.1-times and diabetes was 7.4-times higher than cGDM (MetS-waist circumference-based: 62% vs 34%/MetS-BMI-based: 46% vs 24%; prediabetes: 47.5% vs 15.3%; diabetes: 11.9% vs 1.6%, all p&lt;0.001). These differences remained unchanged after adjusting for GDM-risk factors. Conclusion Compared to cGDM, eGDM was not associated with differences in mental health, but with increased adverse cardiometabolic outcomes, independent of GDM-risk factors and gestational weight gain. This hints to a pre-existing risk-profile in eGDM.
