Abstract
Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by the presence of antiphospholipid antibodies and is associated with thrombotic events and pregnancy complications. The classification and management of APS has evolved over time. The classification criteria for APS include laboratory, macrovascular, microvascular, obstetric, cardiac, and hematologic domains. Management focuses on prevention of thrombotic events and/or anticoagulation as the primary treatment for thrombosis. Postpartum and long-term thromboprophylaxis after delivery are recommended to reduce the risk of thrombotic events. Despite these recommendations, optimal anticoagulation agents and intensity of treatment are still topics of debate. Further research is needed to understand the pathophysiology of APS and improve its management during pregnancy. In this review, we discuss the classification and pathophysiology of APS. Current treatment options and clinical trials are also discussed.

Abstract
OBJECTIVE To date, there is no shared national guideline in Italy for the management of reproductive health in rheumatic diseases (RHRD). The Italian Society for Rheumatology (SIR) has committed to developing clinical practice recommendations to provide guidance on both management and treatment regarding RHRD in Italy. METHODS Using the GRADE-ADOLOPMENT methodology, a systematic literature review was conducted to update the scientific evidence that emerged after the publication of the reference recommendations from the American College of Rheumatology. A multidisciplinary group of 18 clinicians with specialist experience in rheumatology, allergy and clinical immunology, internal medicine, nephrology, gynecology and obstetrics, and neonatology, a professional nurse, a clinical psychologist, and a representative from the National Association of Rheumatic Patients discussed the recommendations in collaboration with the evidence review working group. Subsequently, a group of stakeholders was consulted to examine and externally evaluate the developed recommendations. RESULTS Recommendations were formulated for each area of interest: contraception, assisted reproductive technology, preconception counseling, and use of drugs before, during, and after pregnancy and during breastfeeding, considering both paternal and maternal exposure. CONCLUSIONS The new SIR recommendations provide the rheumatology community with a practical guide based on updated scientific evidence for the management of RHRD.

Abstract
Recurrent spontaneous abortion (RSA) is a multifactorial condition influenced by genetic, hormonal, immunological, and anatomical factors. Thrombophilia, characterized by a heightened propensity for blood clotting, is a significant contributor to RSA. This review examines the mechanisms connecting thrombosis and RSA, focusing on hypercoagulable states, placental thrombosis, inflammation, and endothelial dysfunction. Genetic and acquired thrombophilic factors, such as factor V Leiden mutation, prothrombin gene mutation, protein C and S deficiencies, antithrombin III deficiency, antiphospholipid syndrome, and hyperhomocysteinemia, are discussed in detail. The diagnosis of thrombophilia in RSA entails a comprehensive clinical evaluation, including the assessment of physical examination, medical history and laboratory investigations, although there is still debate over the need for universal screening. Therapeutic strategies, including anticoagulant and antiplatelet therapies, as well as lifestyle modifications, are tailored to individual risk factors and disease severity. Although anticoagulant therapy demonstrates potential in lowering the risk of miscarriage, additional research is necessary to refine treatment protocols and assess long-term outcomes. This review highlights the need for a nuanced approach to managing thrombophilia-associated RSA, balancing diagnostic precision with therapeutic efficacy to improve reproductive outcomes.

Prevalence of Antiphospholipid Antibody Syndrome Among Patients with Recurrent Pregnancy Loss: Impact of the Revised 2023 ACR/EULAR Antiphospholipid Syndrome Criteria. J Clin Med 2024; 13:7698. [PMID: 39768619 PMCID: PMC11677686 DOI: 10.3390/jcm13247698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2024] [Revised: 12/03/2024] [Accepted: 12/13/2024] [Indexed: 01/11/2025] Open
Abstract
Objectives: Current guidelines recommend systematic screening for rheumatic diseases (RDs), including antiphospholipid syndrome (APS), in patients with recurrent pregnancy loss (RPL). However, these recommendations are based on limited evidence, as data on the prevalence of RD in this specific population remain scarce. In particular, the impact of the recent update to the ACR/EULAR classification criteria for APS on the prevalence of RD among RPL patients has yet to be clarified. To address these gaps, this study aims to (i) assess the impact of the 2023 ACR/EULAR APS classification criteria in patients with recurrent pregnancy loss (RPL); and (ii) analyze the prevalence of RD in these patients. Methods: We conducted a retrospective cohort study at Rennes University Hospital. From January 2010 to December 2021, all patients referred to the Clinical Immunology Department for RPL were included. Patients were eligible if they had undergone a full RPL evaluation, according to guidelines. Results: We included 165 women with RPL. APS according to the Sydney criteria was found in 24 (14.5%) patients. No significant differences in obstetric history or clinical signs were observed between APS-positive and APS-negative individuals. Only two patients fulfilled the updated 2023 APS criteria, resulting in 163 (98.8%) patients being classified as having unexplained recurrent pregnancy loss (uRPL). Among them, 108 had a new pregnancy following uRPL, resulting in 87 (81%) live births and 21 (19%) recurrent miscarriages. We did not identify any prognostic factor associated with subsequent pregnancy outcomes, including the patients' antiphospholipid biological profile. We found a prevalence of non-APS RD of only 2.4% in the study population, including systemic lupus erythematosus, rheumatoid arthritis, and Behçet's disease. Conclusions: APS was identified in 14.5% of the patients based on the former Sydney criteria and 1.2% according to the revised criteria. The lack of clinical differences between APS and non-APS patients aligns with previously reported limitations of the Sydney criteria in accurately identifying aPLA-related RPL. According to the rarity of APS as per the updated criteria, future large collaborative trials will be needed to further characterize APS-related RPL patients and to determine the best treatment strategy for future pregnancies.

Abstract
Antiphospholipid syndrome (APS) is a thrombo-inflammatory disease propelled by circulating autoantibodies that recognize cell surface phospholipids and phospholipid-binding proteins. APS is an autoimmune disorder associated with recurrent thrombosis of arterial or venous vessels and/or recurrent obstetric complications as miscarriages. APS can be divided into primary or secondary clinical syndrome because of the possible association with other autoimmune systemic diseases as systemic lupus erythematosus (SLE). Vitamin K antagonists remain the mainstay of treatment for most patients with APS and, based on current data, appear superior to the more targeted direct oral anticoagulants. However, the choice of the type of antithrombotic drug is based on the anamnesis of affected patients: patients with previous arterial or venous thrombosis may benefit from anticoagulants, while patients with previous obstetric diseases may benefit from aspirin, but several clinical exceptions may be evaluated. This short review is dedicated to underlining the main clinical evidence for patients affected by APS or CAPS (catastrophic antiphospholipid syndrome) in order to prevent recurrent thrombosis.

Abstract
OBJECTIVE Substantial morbidity and mortality affect those with antiphospholipid antibodies (aPLs) and antiphospholipid syndrome (APS), yet patient experiences remain poorly understood. This research investigated patient experiences of aPL/APS diagnosis; effects on daily life; and healthcare and treatment. METHODS Patients aged ≥18 years with APS per the Revised Sapporo criteria or with ≥1 positive aPL on ≥2 occasions were recruited from a Canadian multidisciplinary APS clinic to participate in semi-structured in-depth interviews. Interviews were conducted virtually and transcribed verbatim for subsequent thematic analysis. RESULTS Twenty-one patients with aPLs/APS participated; 95.2% were female, mean (SD) age was 45.6 (15.0) years. Most (71.4%) had APS, and 71.4% had aPLs/APS with SLE. Results are presented around patient experiences of aPL/APS diagnosis, effects on daily life, and healthcare and treatment. Participants described medical complications/physical symptoms and the healthcare, lifestyle, and emotional impacts experienced around the time of aPLs/APS diagnosis. In addition to the physical and psychosocial impacts of living with aPLs/APS, patients reported modified leisure activities, altered employment trajectories, and positive and negative impacts on relationships. Impacts on family planning were also a critical component of the aPL/APS lived experience; participants shared experiences of miscarriage, other pregnancy complications, and medication-related challenges (e.g., with low-molecular-weight heparin injections). Challenging aspects of aPL/APS healthcare and treatment were also discussed, particularly related to the lifestyle, physical, and emotional burden of medication use. Although a lack of resources was described, participants expressed trust in healthcare providers when making management decisions or when seeking information. Suggestions for resources included the need for additional medication-related information, examples to help contextualize management behaviours, and additional information for those with aPLs/APS without SLE. CONCLUSION Patients highlighted how the diverse manifestations of aPLs/APS, accentuated by management-related challenges, impose considerable physical and psychosocial burdens. Results will inform the development of patient resources aligned with patient priorities.

Abstract
Antiphospholipid syndrome (APS) is the most frequent acquired thrombophilia of autoimmune basis. Pregnancy complications of APS may include recurrent miscarriage, and placental dysfunction presenting as fetal death, prematurity, intrauterine growth restriction and preeclampsia. For the management of obstetric APS, a coordinated medical-obstetric management is essential, and this should start for a preconceptional visit in order to estimate the individual risk for complications, adjust therapies and establish the indications for preconceptional and first-trimester therapy. The basis of APS therapy during pregnancy is low-dose aspirin, combined in certain clinical scenarios with low-molecular weight heparin. Induction of delivery should not be routinely indicated in the absence of maternal and/or fetal complications. Postpartum management should be warranted.

Abstract
Antiphospholipid syndrome (APS) is characterized by thrombosis (which may be venous, arterial, or microvascular) and/or pregnancy morbidity in association with persistently positive antiphospholipid antibodies. Although thrombosis and pregnancy morbidity are the main clinical criteria for a diagnosis of APS in the revised Sapporo (Sydney) criteria, recently published American College of Rheumatology/European Alliance of Associations for Rheumatology classification criteria for APS have significantly refined the diagnostic algorithm to include a scoring system clustered into 6 clinical domains (macrovascular venous thromboembolism, macrovascular arterial thrombosis, microvascular thrombosis, obstetric, cardiac valve, and hematologic). Diagnosis of APS is complicated by the fact that significant heterogeneity exists in patients' clinical presentation, underlying vascular risk factors, and methods of detecting antiphospholipid antibodies. Despite the autoimmune nature of APS, anticoagulation remains the main strategy for secondary prevention of thrombosis. Furthermore, optimal antithrombotic treatment in APS patients with arterial thrombosis remains controversial due to a paucity of data from randomized controlled studies. In this paper, we present 2 cases and highlight the diagnostic and therapeutic challenges they pose and how we approach them in the light of current evidence.

Abstract
OBJECTIVES Sickle cell disease (SCD) occurs in 2.8 % of our Jamaican antenatal population with homozygous HbSS being most associated with adverse maternal and perinatal outcomes. METHODS A retrospective comparative analysis of HbSS, HbSC and HbSβThal pregnancy outcomes at the University Hospital of the West Indies (UHWI) between January 2012 and December 2022 was conducted. RESULTS Of 120 patients (138 pregnancies), obesity occurred in 36 % (20/56) of the 'non-HbSS' group, i.e. HbSβThal (55 %, 5/9) and HbSC (32 %, 15/47) combined vs. 9.7 % of the HbSS (8/82). HbSS patients had more crises requiring transfusions, acute chest syndrome (ACS), maternal 'near-misses' (OR=10.7, 95 % 3.5-32.3; p<0.001), hospitalizations (OR 7.6, 95 % CI 3.4-16.9; p<0.001), low birth weight (LBW) neonates (OR 3.1, 1.1-8.9; p=0.037) and preterm birth (OR=2.6, 1.2-5.8; p=0.018) compared to HbSC and HbSβThal. Low dose aspirin was prescribed in 43 %. Logistic regression showed those NOT on aspirin (n=76) had more miscarriages (22 v. 2 %), were LESS likely to have a live birth (75 v. 95 % (0.2, 0.04-0.57, p=0.005)), but surprisingly had fewer painful crises (28 v. 46 % (0.5, 0.03-0.9, p=0.03)). CONCLUSIONS HbSS women had a 10-fold excess of maternal near-misses. Additional research may further clarify the effects of aspirin on pregnancy outcomes as related to SCD genotypes.

Branch DW, Lim MY. How I diagnose and treat antiphospholipid syndrome in pregnancy. Blood 2024; 143:757-768. [PMID: 38145574 DOI: 10.1182/blood.2023020727] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 12/11/2023] [Accepted: 12/18/2023] [Indexed: 12/27/2023] Open
Abstract
ABSTRACT Antiphospholipid syndrome (APS) is a rare autoimmune disease characterized by arterial, venous, or microvascular thrombosis, pregnancy morbidities, or nonthrombotic manifestations in patients with persistently positive antiphospholipid antibodies. These antibodies bind cellular phospholipids and phospholipid-protein complexes resulting in cellular activation and inflammation that lead to the clinical features of APS. Our evolving understanding of APS has resulted in more specific classification criteria. Patients meeting these criteria should be treated during pregnancy according to current guidelines. Yet, despite treatment, those positive for lupus anticoagulant have at least a 30% likelihood of adverse pregnancy outcomes. Patients with recurrent early miscarriage or fetal death in the absence of preeclampsia or placental insufficiency may not meet current classification criteria for APS. Patients with only low titer anticardiolipin or anti-β(2)-glycoprotein I antibodies or immunoglobulin M isotype antibodies will not meet current classification criteria. In such cases, clinicians should implement management plans that balance potential risks and benefits, some of which involve emotional concerns surrounding the patient's reproductive future. Finally, APS may present in pregnancy or postpartum as a thrombotic microangiopathy, a life-threatening condition that may initially mimic preeclampsia with severe features but requires a very different treatment approach.

Abstract
OBJECTIVE To identify strategies to reduce maternal and neonatal morbidity related to preeclampsia. MATERIAL AND METHODS The quality of evidence of the literature was assessed following the GRADE® method with questions formulated in the PICO format (Patients, Intervention, Comparison, Outcome) and outcomes defined a priori and classified according to their importance. An extensive bibliographic search was performed on PubMed, Cochrane, EMBASE and Google Scholar databases. The quality of the evidence was assessed (high, moderate, low, very low) and recommendations were formulated as a (i) strong, (ii) weak or (iii) no recommendation. The recommendations were reviewed in two rounds with external reviewers (Delphi survey) to select the consensus recommendations. RESULTS Preeclampsia is defined by the association of gestational hypertension (systolic blood pressure≥140mmHg and/or diastolic blood pressure≥90mmHg) and proteinuria≥0.3g/24h or a Proteinuria/Creatininuria ratio≥30mg/mmol occurring after 20 weeks of gestation. Data from the literature do not show any benefit in terms of maternal or perinatal health from implementing a broader definition of preeclampsia. Of the 31 questions, there was agreement between the working group and the external reviewers on 31 (100%). In general population, physical activity during pregnancy should be encouraged to reduce the risk of preeclampsia (Strong recommendation, Quality of the evidence low) but an early screening based on algorithms (Weak recommendation, Quality of the evidence low) or aspirin administration (Weak recommendation, Quality of the evidence very low) is not recommended to reduce maternal and neonatal morbidity related to preeclampsia. In women with preexisting diabetes or hypertension or renal disease, or multiple pregnancy, the level of evidence is insufficient to determine whether aspirin administration during pregnancy is useful to reduce maternal and perinatal morbidity (No recommendation, Quality of the evidence low). In women with a history of vasculo-placental disease, low dose of aspirin (Strong recommendation, Quality of the evidence moderate) at a dosage of 100-160mg per day (Weak recommendation, Quality of the evidence low), ideally before 16 weeks of gestation and not after 20 weeks of gestation (Strong recommendation, Quality of the evidence low) until 36 weeks of gestation (Weak recommendation, Quality of the evidence very low) is recommended. In a high-risk population, additional administration of low molecular weight heparin is not recommended (Weak recommendation, Quality of the evidence moderate). In case of preeclampsia (Weak recommendation, Quality of the evidence low) or suspicion of preeclampsia (Weak recommendation, Quality of the evidence moderate, the assessment of PlGF concentration or sFLT-1/PlGF ratio is not routinely recommended) in the only goal to reduce maternal or perinatal morbidity. In women with non-severe preeclampsia antihypertensive agent should be administered orally when the systolic blood pressure is measured between 140 and 159mmHg or diastolic blood pressure is measured between 90 and 109mmHg (Weak recommendation, Quality of the evidence low). In women with non-severe preeclampsia, delivery between 34 and 36+6 weeks of gestation reduces severe maternal hypertension but increases the incidence of moderate prematurity. Taking into account the benefit/risk balance for the mother and the child, it is recommended not to systematically induce birth in women with non-severe preeclampsia between 34 and 36+6 weeks of gestation (Strong recommendation, Quality of evidence high). In women with non-severe preeclampsia diagnosed between 37+0 and 41 weeks of gestation, it is recommended to induce birth to reduce maternal morbidity (Strong recommendation, Low quality of evidence), and to perform a trial of labor in the absence of contraindication (Strong recommendation, Very low quality of evidence). In women with a history of preeclampsia, screening maternal thrombophilia is not recommended (Strong recommendation, Quality of the evidence moderate). Because women with a history of a preeclampsia have an increased lifelong risk of chronic hypertension and cardiovascular complications, they should be informed of the need for medical follow-up to monitor blood pressure and to manage other possible cardiovascular risk factors (Strong recommendation, Quality of the evidence moderate). CONCLUSION The purpose of these recommendations was to reassess the definition of preeclampsia, and to determine the strategies to reduce maternal and perinatal morbidity related to preeclampsia, during pregnancy but also after childbirth. They aim to help health professionals in their daily clinical practice to inform or care for patients who have had or have preeclampsia. Synthetic information documents are also offered for professionals and patients.

Abstract
OBJECTIVE This systematic review and meta-analysis (SRMA) aims to compare the efficacy of combining low molecular weight heparin (LMWH) and aspirin against aspirin alone in preventing preeclampsia (PE) and small for gestational age (SGA) neonates in women at moderate and high risks. STUDY DESIGN The included studies were nonrandomized and randomized clinical trials (RCTs) enrolling women at moderate and high risks for developing preeclampsia. PubMed/Medline, Cochrane Library, Embase, and Grey literature (including ClinicalTrials.gov) were searched. RESULTS Out of 4,762 records, 7 nonrandomized studies and 12 RCTs (enrolling 545 and 1,677 women, respectively) were selected. Although the studies were clinically heterogeneous, the conduction of quantitative analysis was feasible. Regarding RCTs, the odds of early-onset preeclampsia was reduced by 89% (pooled odds ratio [OR] = 0.11, 95% confidence interval [CI]: 0.01-0.93, p = 0.04) in women with thrombophilia, the incidence of SGA neonates below the 5th percentile by 48% (pooled OR = 0.52, 95% CI: 0.28-0.96, p = 0.04) in women with a history of preeclampsia and/or SGA neonates, and the incidence of SGA neonates below the 10th percentile by 31% (pooled OR = 0.69, 95% CI: 0.50-0.96, p = 0.03) in the whole population. CONCLUSION Concerning the whole studied population, combined anticoagulant therapy is not superior to aspirin alone. However, it may be more effective in preventing early-onset preeclampsia regarding women with thrombophilia, SGA neonates below the 5th percentile regarding women with a history of preeclampsia and/or SGA, and SGA neonates below the 10th percentile in moderate- or high-risk women. The above mixed but promising results need to be envisaged with caution due to the clinical heterogeneity of the included studies which is the main limitation of our research. Nevertheless, the strict and narrow inclusion search criteria, and the appropriate subgroup analysis are its main strengths. More RCTs with homogeneous populations and stricter inclusion criteria are needed to confirm these results. KEY POINTS · Combined therapy is not superior to aspirin alone.. · Combined therapy in women with thrombophilia may protect against early-onset preeclampsia.. · Combined therapy in moderate/high-risk women may protect against SGA <10th percentile neonates..

Abstract
Systemic lupus erythematosus (SLE), a prevalent autoimmune disease predominantly affecting women of childbearing age, presents ongoing challenges despite notable advances in diagnosis and treatment. Although survival rates for SLE patients have significantly improved, pregnancy continues to pose a considerable obstacle. Addressing this critical need for enhanced reproductive and prenatal care, there is a pressing imperative to establish standardized protocols for peri-gestational monitoring and treatment in SLE patients. This guideline is jointly sponsored by the National Clinical Research Center for Dermatologic and Immunologic Diseases (NCRC-DID), the Chinese Systemic Lupus Erythematosus Treatment and Research Group (CSTAR), and the Chinese Research Committee of Pregnancy and Reproduction in Autoimmune Rheumatic Diseases (CHOPARD). Thirteen pertinent clinical questions have been generated through several rounds of rigorous clinical and methodological expert discussions and selections for a comprehensive understanding of key aspects in this domain. Guided by thorough examination of research evidence and expert perspectives, the formulated recommendations aim to optimize pregnancy success rates, reduce maternal and infant mortality rates, and ultimately enhance the overall well-being of SLE patients.

Abstract
PURPOSE OF REVIEW Antiphospholipid syndrome (APS) is an acquired thrombo-inflammatory disease that has morbid and sometimes devastating effects on patients and their families. This review will discuss the most recent international societal treatment guidelines and propose practical management algorithms for various APS sub-types. RECENT FINDINGS APS represents a disease spectrum. Although thrombosis and pregnancy morbidities are traditional hallmarks of APS, a variety of extra-criteria clinical phenotypes can often be seen, which makes clinical management more challenging. Primary APS thrombosis prophylaxis should take a risk-stratified approach. Although vitamin K antagonists (VKAs) or heparin/low molecular weight heparin (LMWH) remain the preferred treatment for secondary APS thrombosis prophylaxis, some international society guidelines support the use of direct oral anticoagulants (DOACs) in certain circumstances. Careful monitoring and individualized obstetric care with the use of aspirin and heparin/LMWH will improve pregnancy outcomes among pregnant individuals with APS. Treatment of microvascular and catastrophic APS remains challenging. While the addition of various immunosuppressive agents is often utilized, further systemic evaluations of their use are warranted before definitive recommendations can be made. Several new therapeutic strategies are on the horizon that might enable more personalized and targeted APS management in the near future. SUMMARY Although the knowledge of APS pathogenesis has grown in recent years, the management principles and strategies are largely unchanged. There is an unmet need for evaluating pharmacological agents, beyond anticoagulants, that target diverse thromboinflammatory pathways.

Abstract
Women with antiphospholipid syndrome (APS) have an increased risk of adverse pregnancy outcomes. To define clinical, serologic, and treatment factors that can predict outcomes in pregnant women with APS. Retrospective cohort study of pregnant women with APS evaluated at a university medical center between January 2006 and August 2021. Demographics, personal and family history of thrombosis, autoimmune disease, antithrombotic use, pregnancy outcomes, maternal and fetal complications were collected. We compared pregnancy outcomes in the presence or absence of lupus anticoagulant (LA), systemic lupus erythematosus (SLE), prior thrombosis or pregnancy losses, and antithrombotic use. There were 169 pregnancies in 50 women; 79 (46.7%) occurred after maternal diagnosis of APS. The most common antithrombotic regimen was aspirin and low molecular weight heparin (LMWH) in 26.6% of pregnancies; 55.0% of all pregnancies and 68.4% of pregnancies post-APS diagnosis resulted in a live birth. In age-adjusted analyses, aspirin plus LMWH regardless of dosage was associated with significantly higher odds of live birth compared with no antithrombotic use (OR = 7.5, p < 0.001) and compared with aspirin alone (OR = 13.2, p = 0.026). SLE increased the risk for preterm birth and preeclampsia. A positive LA did not impact the outcomes evaluated and anticardiolipin IgM decreased the risk of pre-eclampsia. The presence of SLE is a significant risk factor for adverse outcomes in pregnant women with APS. Treatment with LMWH and aspirin was superior to aspirin alone. The creation of a global registry may be useful in improving the management of these patients.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune prothrombotic disease characterized by thrombosis and/or pregnancy complications caused by antiphospholipid antibodies (aPL). The history of APS can be traced back to observations made during screening programs for syphilis conducted in the mid-20th century, with identification of patients with the so-called biological false-positive serological reactions for syphilis. Initial observation linking aPL with recurrent miscarriages was first reported more than 40 years ago. Since then, our understanding of the pathogenesis and management of APS has evolved markedly. Although APS is an autoimmune disease, anticoagulation mainly with vitamin K antagonists (VKAs) rather than immunomodulation, is the treatment of choice for thrombotic APS. Direct acting oral anticoagulants are inferior to VKAs, especially those with triple-positive APS and arterial thrombosis. Inflammation, complement activation, and thrombosis in the placenta may contribute to pathogenesis of obstetric APS. Heparin, mainly low-molecular-weight heparin, and low-dose aspirin represent the treatments of choice for women with obstetric complications. Increasingly, immunomodulatory agents such as hydroxychloroquine for thrombotic and obstetric APS are being used, especially in patients who are refractory to present standard treatment.

Abstract
Antiphospholipid syndrome (APS) is a thrombo-inflammatory disease propelled by circulating autoantibodies that recognize cell surface phospholipids and phospholipid binding proteins. The result is an increased risk of thrombotic events, pregnancy morbidity, and various other autoimmune and inflammatory complications. Although antiphospholipid syndrome was first recognized in patients with lupus, the stand alone presentation of antiphospholipid syndrome is at least equally common. Overall, the diagnosis appears to affect at least one in 2000 people. Studies of antiphospholipid syndrome pathogenesis have long focused on logical candidates such as coagulation factors, endothelial cells, and platelets. Recent work has shed light on additional potential therapeutic targets within the innate immune system, including the complement system and neutrophil extracellular traps. Vitamin K antagonists remain the mainstay of treatment for most patients with thrombotic antiphospholipid syndrome and, based on current data, appear superior to the more targeted direct oral anticoagulants. The potential role of immunomodulatory treatments in antiphospholipid syndrome management is receiving increased attention. As for many systemic autoimmune diseases, the most important future direction is to more precisely identify mechanistic drivers of disease heterogeneity in pursuit of unlocking personalized and proactive treatments for patients.

Abstract
Objective To evaluate the implementation of low-dose aspirin in pregnancy for the prevention of utero-placental complications among gynecologists in the Netherlands between 2016 and 2021. In this timeframe, a national guideline about aspirin in pregnancy was introduced by the Dutch Society of Obstetrics and Gynecology. Materials and methods A national online survey among Dutch gynecologists and residents was performed. An online questionnaire was distributed among the members of the Dutch Society of Obstetrics and Gynecology in April 2016 and April 2021. Main outcome measure was the proportion of gynecologists indicating prescription of aspirin in pregnancy for high and moderate risk indications. Results In 2016, 133 respondents completed the survey, and in 2021 231. For all indications mentioned in the guideline there was an increase in prescribing aspirin in 2021 in comparison to 2016. More specifically, the percentage of gynecologists prescribing aspirin for a history of preeclampsia before 34 weeks, between 34 and 37 weeks and at term increased from respectively 94% to 100%, 39% to 98%, and 15% to 97%. Consultant obstetricians and respondents working in an university hospital did not more often indicate the prescription of aspirin for tertiary care indications in 2021. Future use of a prediction model was suggested in the narrative comments. Conclusion Implementation of aspirin in pregnancy among Dutch gynecologists substantially improved after a five year timeframe in which the national guideline on aspirin during pregnancy was introduced and trials confirming the effect of aspirin were published.

Abstract
The effect of glucocorticoid therapy on women with unexplained positive autoantibodies is under debate. This systemic review and meta-analysis were performed to evaluate whether glucocorticoid administration can improve the pregnancy outcome of this population. Relevant publications were searched from databases, and a total of seven prospective and retrospective cohort studies that investigated the effects of glucocorticoid administration on women with unexplained positive autoantibodies, were included. The outcomes of our systematic review and meta-analysis were measured in terms of risk ratios (RR) with 95% confidence intervals (CI) using fixed or random effect models. We found that glucocorticoid treatment improved the clinical pregnancy rate (RR 2.19, 95% CI 1.64–2.92) and live birth rate (RR 1.92, 95% CI 1.17–3.16), especially when glucocorticoid administration was started before pregnancy (clinical pregnancy rate: RR 2.30, 95% CI 1.58–3.34; live birth rate: RR 2.30, 95% CI 1.58–3.34). However, no effect of glucocorticoids on the miscarriage rate was found (RR 0.75, 95% CI 0.55–1.02) regardless of the time of drug administration. Our systematic review and meta-analysis support the rational use of glucocorticoids in women with unexplained positive autoantibodies.

Basak T, Ain R. Molecular regulation of trophoblast stem cell self-renewal and giant cell differentiation by the Hippo components YAP and LATS1. Stem Cell Res Ther 2022; 13:189. [PMID: 35526072 PMCID: PMC9080189 DOI: 10.1186/s13287-022-02844-w] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Accepted: 03/22/2022] [Indexed: 11/25/2022] Open
Abstract
Background Trophoblast stem cells (TSCs), the precursors of trophoblast cells of placenta, possess the potential to differentiate into various trophoblastic subtypes in vitro. Establishment of extraembryonic trophoblastic lineage is preceded by the “outside versus inside” positional information in preimplantation embryos, critically synchronized by the Hippo components. Abundant expression of Hippo effector YAP in TSCs and differentiated cells with paucity of information on Hippo regulation of TSC proliferation/differentiation led us test the hypothesis that Hippo dynamics is one of the regulators of TSC proliferation/differentiation. Methods Blastocyst-derived murine TSCs were used. Dynamics of Hippo components were analyzed using immunofluorescence, western blotting, immunoprecipitation, qRT-PCR. Interaction studies were performed using full-length and deletion constructs. BrdU incorporation assay, flow cytometry-based polyploidy analysis and confocal microscopy were used to decipher the underlying mechanism. Results YAP translocates to the nucleus in TSCs and utilizes its WW2 domain to interact with the PPQY motif of the stemness factor, CDX2. YAP limits TSC proliferation with associated effect on CDX2 target CyclinD1. Trophoblast giant cells (TGC) differentiation is associated with cytoplasmic retention of YAP, heightened pYAPSer127, decrease in the level of the core Hippo component, LATS1, which thereby impedes LATS1-LIMK2 association. Decreased LATS1-LIMK2 complex formation in TGCs was associated with elevated pLIMK2Thr505 as well as its target pCOFILINSer3. Precocious overexpression of LATS1 during trophoblast differentiation decreased TGC marker, Prl2c2, diminished pLIMK2Thr505 and inactive COFILIN (pCOFILINSer3) while COFILIN-phosphatase, CHRONOPHIN remained unchanged. LATS1 overexpression inhibited trophoblast endoreduplication with smaller-sized TGC-nuclei, lower ploidy level and disintegrated actin filaments. Inhibition of LIMK2 activity recapitulated the effects of LATS1 overexpression in trophoblast cells. Conclusion These results unveil a multilayered regulation of trophoblast self-renewal and differentiation by the Hippo components.

Abstract
This viewpoint article on a forecast of clinically meaningful changes in the management of systemic lupus erythematosus (SLE) in the next 10 years is based on a review of the current state of the art. The groundwork has been laid by a robust series of classification criteria and treatment recommendations that have all been published since 2019. Building on this strong foundation, SLE management predictably will take significant steps forward. Assessment for lupus arthritis will presumably include musculoskeletal sonography. Large-scale polyomics studies are likely to unravel more of the central immune mechanisms of the disease. Biomarkers predictive of therapeutic success may enter the field; the type I interferon signature, as a companion for use of anifrolumab, an antibody against the common type I interferon receptor, is one serious candidate. Besides anifrolumab for nonrenal SLE and the new calcineurin inhibitor voclosporin in lupus nephritis, both of which are already approved in the United States and likely to become available in the European Union in 2022, several other approaches are in advanced clinical trials. These include advanced B cell depletion, inhibition of costimulation via CD40 and CD40 ligand (CD40L), and Janus kinase 1 (Jak1) and Tyrosine kinase 2 (Tyk2) inhibition. At the same time, essentially all of our conventional therapeutic armamentarium will continue to be used. The ability of patients to have successful SLE pregnancies, which has become much better in the last decades, should further improve, with approaches including tumor necrosis factor blockade and self-monitoring of fetal heart rates. While we hope that the COVID-19 pandemic will soon be controlled, it has highlighted the risk of severe viral infections in SLE, with increased risk tied to certain therapies. Although there are some data that a cure might be achievable, this likely will remain a challenge beyond 10 years from now.

Abstract
OBJECTIVE To investigate the prevalence of off-label aspirin indications and the level of scientific support for off-label indications of aspirin in gynaecology and obstetrics outpatients. DESIGN A retrospective cross-sectional study. SETTING Two tertiary hospitals (a general hospital and a women and children's specialised hospital) in Xiamen, a city located on the southeastern coast of China. PARTICIPANTS A total of 4257 prescriptions were included for 2091 female patients aged >18 who visited the gynaecology and obstetrics outpatient clinics and received aspirin treatment. OUTCOME MEASURES The primary measure of this study was the proportion of off-label indications and of off-label indications supported by strong scientific evidence. Evidence from clinical guidelines and Micromedex is shown using descriptive statements. On-label indications of drugs in the same class as aspirin were also referred to for off-label aspirin use without strong evidence support. RESULTS All indications of aspirin on outpatient prescriptions were determined as off-label use in this study. The most frequent off-label indication was recurrent miscarriage (2244 prescriptions, 52.71%). Totally, 30.94% of the prescriptions were supported by strong evidence for indications, including recurrent miscarriage with antiphospholipid syndrome and prophylaxis for pre-eclampsia. No drugs in the same class as aspirin had on-label indications for off-label aspirin use without strong evidence support. CONCLUSIONS This study demonstrated that all indications of aspirin used in gynaecology and obstetrics outpatients at the two tertiary hospitals were off-label and not always supported by strong evidence, implicating that physicians should be cautious when issuing off-label prescriptions. More original clinical research on off-label aspirin use is needed to provide reference for routine clinical practice.

Am J Obstet Gynecol 2022; 226:S1126-S1144.e17. [PMID: 34301348 DOI: 10.1016/j.ajog.2020.11.006] [Citation(s) in RCA: 42] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 11/04/2020] [Accepted: 11/04/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Evidence on the impact of low-molecular-weight heparin, alone or in combination with low-dose aspirin, for the prevention for preeclampsia in high-risk patients is conflicting. OBJECTIVE We conducted a meta-analysis of studies published to assess the effectiveness of low-molecular-weight heparin for the prevention of preeclampsia and other placenta-related complications in high-risk women. DATA SOURCES A systematic search was performed to identify relevant studies, using the databases PubMed and Cochrane Central Register of Controlled Trials, without publication time restrictions. STUDY ELIGIBILITY CRITERIA Randomized controlled trials comparing treatment with low-molecular-weight heparin or unfractionated heparin (with or without low-dose aspirin), in high-risk women, defined as either history of preeclampsia, intrauterine growth restriction, fetal demise, or miscarriage or being at high risk after first-trimester screening of preeclampsia. STUDY APPRAISAL AND SYNTHESIS METHODS The systematic review was conducted according to the Cochrane Handbook guidelines. The primary outcome was the development of preeclampsia. We performed prespecified subgroup analyses according to combination with low-dose aspirin, low-molecular-weight heparin type, gestational age when treatment was started, and study population (patients with thrombophilia, at high risk of preeclampsia or miscarriage). Secondary outcomes included small for gestational age, perinatal death, miscarriage, and placental abruption. Pooled odds ratios with 95% confidence intervals were calculated using a random-effects model. Quality of evidence was assessed using the grading of recommendations assessment, development, and evaluation methodology. RESULTS A total of 15 studies (2795 participants) were included. In high-risk women, treatment with low-molecular-weight heparin was associated with a reduction in the development of preeclampsia (odds ratio, 0.62; 95% confidence interval, 0.43-0.90; P=.010); small for gestational age (odds ratio, 0.61; 95% confidence interval, 0.44-0.85; P=.003), and perinatal death (odds ratio, 0.49; 95% confidence interval, 0.25-0.94; P=.030). This reduction was stronger if low-molecular-weight heparin was started before 16 weeks' gestation (13 studies, 2474 participants) for preeclampsia (odds ratio, 0.55; 95% confidence interval, 0.39-0.76; P=.0004). When only studies including low-dose aspirin as an intervention were analyzed (6 randomized controlled trials, 920 participants), a significant reduction was observed in those with combined treatment (low-molecular-weight heparin plus low-dose aspirin) compared with low-dose aspirin alone (odds ratio, 0.62; 95% confidence interval, 0.41-0.95; P=.030). Overall, adverse events were neither serious nor significantly different. Quality of evidence ranged from very low to moderate, mostly because of the lack of blinding, imprecision, and inconsistency. CONCLUSION Low-molecular-weight heparin use was associated with a significant reduction in the risk of preeclampsia and other placenta-mediated complications in high-risk women and when treatment was started before 16 weeks' gestation. Combined treatment with low-dose aspirin was associated with a significant reduction in the risk of preeclampsia compared with low-dose aspirin alone. However, there exists important clinical and statistical heterogeneity, and therefore, these results merit confirmation in large well-designed clinical trials.

Abstract
OBJECTIVE To describe the baseline characteristics of patients with positivity for antiphospholipid antibodies (aPLs) who were enrolled in an international registry, the Antiphospholipid Syndrome (APS) Alliance for Clinical Trials and International Networking (APS ACTION) clinical database and repository, overall and by clinical and laboratory subtypes. METHODS The APS ACTION registry includes adults who persistently had positivity for aPLs. We evaluated baseline sociodemographic and aPL-related (APS classification criteria and "non-criteria") characteristics of patients overall and in subgroups (aPL-positive without APS, APS overall, thrombotic APS only, obstetric APS only, and both thrombotic APS/obstetric APS). We assessed baseline characteristics of patients tested for the presence of three aPLs (lupus anticoagulant [LAC] test, anticardiolipin antibody [aCL], and anti-β2 -glycoprotein I [anti-β2 GPI]) antibodies by aPL profiles (LAC only, single, double, and triple aPL positivity). RESULTS The 804 aPL-positive patients assessed in the present study had a mean age of 45 ± 13 years, were 74% female, and 68% White; additionally, 36% had other systemic autoimmune diseases. Of these 804 aPL-positive patients, 80% were classified as having APS (with 55% having thrombotic APS, 9% obstetric APS, and 15% thrombotic APS/obstetric APS). In the overall cohort, 71% had vascular thrombosis, 50% with a history of pregnancy had obstetric morbidity, and 56% had experienced at least one non-criteria manifestation. Among those with three aPLs tested (n = 660), 42% were triple aPL-positive. While single-, double-, and triple aPL-positive subgroups had similar frequencies of vascular, obstetric, and non-criteria events, these events were lowest in the single aPL subgroup, which consisted of aCLs or anti-β2 GPI only. CONCLUSION Our study demonstrates the heterogeneity of aPL-related clinical manifestations and laboratory profiles in a multicenter international cohort. Within single aPL positivity, LAC may be a major contributor to clinical events. Future prospective analyses, using standardized core laboratory aPL tests, will help clarify aPL risk profiles and improve risk stratification.

Abstract
In the past decade, the incidence of recurrent pregnancy loss (RPL) has increased significantly, and immunological disorders have been considered as one of the possible causes contributing to RPL. The presence of antinuclear antibodies (ANAs) is regarded as a typical antibody of autoimmunity. However, the relationship between the presence of ANAs and RPL, the underlying mechanism, and the possible role of immunotherapy is still controversial. The aim of this mini review is to assess the association between ANAs and RPL and the effects of immunotherapy on pregnancy outcomes in women with positive ANAs and a history of RPL from the available data and to provide a relevant reference basis for clinical application in this group of women.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune disorder that causes venous, arterial and small-vessel thrombosis, pregnancy loss, and premature birth. Cardiac valvular disease, renal thrombotic microangiopathy, thrombocytopenia, hemolytic anemia, and cognitive impairment are some of its other clinical symptoms. Antiphospholipid antibodies cause endothelial cells, monocytes, and platelets to become activated, as well as an increase in tissue factor and thromboxane A2. Complement activation might play a key function in pathogenesis. Long-term oral anticoagulation is used to treat thrombosis, and individuals having arterial episodes should be treated quickly. Patients with systemic lupus erythematosus (SLE), as well as those with solely obstetric antiphospholipid syndrome, should get primary thromboprophylaxis. Obstetric care is based on a combination of medical and obstetric high-risk management, as well as aspirin and heparin therapy. Possible supplementary therapy for this condition is hydroxychloroquine. Statins, rituximab, and novel anticoagulant medicines are all potential future treatments for non-pregnant individuals with antiphospholipid syndrome. We aim to review the role of direct-acting oral anticoagulants (DOACs) as thromboprophylactic drugs in the treatment of APS in this article. The treatment of venous thromboembolism has been transformed by a new class of DOACs. These drugs, such as rivaroxaban, function by inhibiting factor Xa directly. Not only do they have known anticoagulant actions, but they also obviate the need for dosage monitoring and modification, in contrast to warfarin. We conducted an exhaustive literature search of PubMed/MEDLINE and Google Scholar Indexes using the keywords "Antiphospholipid syndrome," "thromboprophylaxis," and "oral anticoagulants" up to September 2021. We found that DOACs have been shown to be non-inferior to warfarin in a variety of anticoagulation situations in a number of high-powered clinical studies. In many hypercoagulable conditions such as APS, DOACs are quickly establishing themselves as first-line therapy. This article is focused on comprehensively reviewing the mechanism of action of DOACs, their role as thromboprophylactic drugs, risks and complications of DOACs, and comparing their efficacy with the standard treatment protocol and warfarin.

Abstract
OBJECTIVE Unexplained recurrent miscarriage (uRM) has caused serious distress to women of childbearing age, and effective treatment is particularly important. The aim of this meta-analysis is to compare the efficacy of low molecular weight heparin (LMWH) and LMWH combined with aspirin for uRM. METHODS Databases including PubMed, Web of Science, Embase, Scopus and the Cochrane Library databases were electronically searched to identify randomized controlled trials that reported the LMWH or LMWH combined with aspirin for women with uRM and negative antiphospholipid antibodies (aPL). The retrieval time is limited from inception to June 2021. Two reviewers independently screened literature, extracted data, and assessed risk bias of included studies. Meta-analysis was performed by using STATA 12.0 software. RESULTS A total of 7 studies involving 1849 patients were included. The meta-analysis results showed that compared with the control group, both LMWH and LMWH + aspirin interventions showed no substantial influence on miscarriage rate (LMWH: RR = 0.69, 95%CI: 0.34-1.39, P = 0.293, LMWH + aspirin: RR = 0.62, 95%CI: 0.30-1.27, P = 0.19) and the occurrence of pre-eclampsia (LMWH: RR = 1.1, 95%CI: 0.53-2.31, P = 0.792; LMWH + aspirin: RR = 1.49, 95%CI: 0.25-8.79, P = 0.662). LMWH therapy had no influence on the live births (RR = 0.99, 95%CI: 0.92-1.06, P = 0.72). Subgroup analysis showed that enoxaparin is not effective in women with uRM and negative aPL (miscarriage rate: RR = 0.82, 95%CI: 0.31-2.19, P = 0.695; pre-eclampsia: RR = 1.03, 95%CI: 0.46-2.33, P = 0.936). CONCLUSIONS LMWH and LMWH combined with aspirin therapy cannot improve the pregnancy outcome of women with uRM and negative aPL. However, the above conclusions are still required to be verified through more RCTs due to the limited quantity of included studies.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune disease characterized by clinical manifestations such as thrombosis and obstetric complications with documented persistence of antiphospholipid antibodies (aPLs). Recent studies have revealed that the cause of aPL-related obstetric complications is dysfunction of placental trophoblasts and inflammation of the maternal-fetal interface induced by aPLs, not thrombosis. Although aPLs are associated with recurrence of serious complications during pregnancy, appropriate combination therapy with heparin and low-dose aspirin can improve the course of 70-80% of subsequent pregnancies. Preconception counseling and patient-tailored treatment are fundamental to improving maternal and fetal outcomes. Non-anticoagulant treatments such as hydroxychloroquine and statins are being developed for cases refractory to conventional treatment. Risk factors for thrombosis after pregnancy complications were identified based on the analysis of large databases of obstetric APS.

Abstract
BACKGROUND The combination of low-dose aspirin (LDA) and low-molecular-weight heparin (LMWH) until the end of gestation are the currently the accepted standard of care for the treatment of antiphospholipid-related obstetric disorders. In refractory cases, hydroxychloroquine (HCQ) can be added to this standard of care. OBJECTIVE To evaluate the haemostatic safety of LDA and LMWH (medium to high prophylactic doses) during pregnancy and the puerperium in women with both full-blown obstetric antiphospholipid syndrome (OAPS) (Sydney criteria) and noncriteria - incomplete - OAPS. STUDY DESIGN Retrospective/prospective multicentre observational study. Obstetric background, laboratory categories, delivery mode, antithrombotic regimens and bleeding complications were compared. SETTING A total of 30 tertiary European hospitals. PATIENTS Mainly, Caucasian/Arian pregnant women were included. Other ethnicities were minimally present. Women were controlled throughout pregnancy and puerperium. MAIN OUTCOME MEASURES The primary end-point was to evaluate the number of major and minor haemorrhagic complications in this cohort of women. Neuraxial anaesthetic bleeding complications were particularly assessed. Secondly, we aimed to compare local/general bleeding events between groups. RESULTS We studied 1650 women, of whom 1000 fulfilled the Sydney criteria of the OAPS and 650 did not (noncriteria OAPS). Data on antithrombotic-related complications were available in 1075 cases (65.15%). Overall, 53 (4.93%) women had bleeding complications, with 34 being considered minor (3.16%) and 19 major (1.76%). Neither obstetric complications nor laboratory categories were bleeding-related. Assisted vaginal delivery and caesarean section were related to local haemorrhage. Heparin doses and platelet count were not associated with major bleeding. CONCLUSIONS LDA and medium to high prophylactic LMWH during pregnancy in women with full-blown OAPS/noncriteria OAPS are safe. A slight increase in bleeding risk was noted in instrumental deliveries. No women who underwent spinal or epidural anaesthesia suffered bleeding complications. No haemorrhage was observed in cases where HCQ was added to standard therapy.

Abstract
Women with criteria and non-criteria obstetric antiphospholipid syndrome (APS) carry an increased risk of pregnancy complications, including fetal growth restriction (FGR). The management of obstetric APS traditionally involves clinicians, obstetricians and gynaecologists; however, the most appropriate prophylactic treatment strategy for FGR prevention in APS is still debated. We performed a systematic review and network meta-analysis (NetMA) to summarize current evidence on pharmacological treatments for the prevention of FGR in APS. We searched PubMed and Embase from inception until July 2020, for randomized controlled trials and prospective studies on pregnant women with criteria or non-criteria obstetric APS. NetMA using a frequentist framework were conducted for the primary outcome (FGR) and for secondary outcomes (fetal or neonatal death and preterm birth). Adverse events were narratively summarised. Out of 1124 citations, we included eight studies on 395 pregnant patients with obstetric APS treated with low-dose aspirin (LDA) + unfractionated heparin (UFH) (n = 132 patients), LDA (n = 115), LDA + low molecular weight heparin (n = 100), LDA + corticosteroids (n = 29), LDA + UFH + intravenous immunoglobulin (n = 7), or untreated (n = 12). No difference among treatments emerged in terms of FGR prevention, but estimates were largely imprecise, and most studies were at high/unclear risk of bias. An increased risk of fetal or neonatal death was found for LDA monotherapy as compared to LDA + heparin, and for no treatment as compared to LDA + corticosteroids. The risk of preterm birth was higher for LDA + UFH + IVIg as compared to LDA or LDA + heparin, and for LDA + corticosteroids as compared to LDA or LDA + LMWH. No treatment was associated with an increased risk of bleeding, thrombocytopenia or osteopenia.

Abstract
Aspirin and heparin are widely used to reduce the risk of recurrent pregnancy loss in women with antiphospholipid syndrome. This practice is based on only a few intervention studies, and uncertainty regarding benefits and risk remains. In this case-based review, we summarize the available evidence and address the questions that are most important for clinical practice. We performed a systematic review of randomized controlled trials assessing the effect of heparin (low molecular weight heparin [LMWH] or unfractionated heparin [UFH]), aspirin, or both on live birth rates in women with persistent antiphospholipid antibodies and recurrent pregnancy loss. Eleven trials including 1672 women met the inclusion criteria. Aspirin only did not increase live birth rate compared to placebo in one trial of 40 women (risk ratio [RR] 0.94; 95% confidence interval [CI] 0.71-1.25). One trial of 141 women reported a higher live birth rate with LMWH only than with aspirin only (RR 1.20; 95% CI 1.00-1.43). Five trials totaling 1295 women compared heparin plus aspirin with aspirin only. The pooled RR for live birth was 1.27 (95% CI 1.09-1.49) in favor of heparin plus aspirin. There was significant heterogeneity between the subgroups of LMWH and UFH (RR for LWMH plus aspirin versus aspirin 1.20, 95% CI: 1.04-1.38; RR for UFH plus aspirin versus aspirin 1.74, 95% CI: 1.28-2.35; I2 78.9%, p = .03). Characteristics of participants and adverse events were not uniformly reported. Heparin (LMWH or UFH) plus aspirin may improve live birth rates in women with recurrent pregnancy loss and antiphospholipid antibodies, but evidence is of low certainty.

Abstract
BACKGROUND Venous thromboembolism (VTE), although rare, is a major cause of maternal mortality and morbidity. Some women are at increased risk of VTE during pregnancy and the early postnatal period (e.g. caesarean section, family history of VTE, or thrombophilia), and so prophylaxis may be considered. As some methods of prophylaxis carry risks of adverse effects, and risk of VTE is often low, benefits of thromboprophylaxis may be outweighed by harms. OBJECTIVES To assess the effects of thromboprophylaxis during pregnancy and the early postnatal period on the risk of venous thromboembolic disease and adverse effects in women at increased risk of VTE. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (18 October 2019). In addition, we searched ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP) for unpublished, planned and ongoing trial reports (18 October 2019). SELECTION CRITERIA Randomised trials comparing one method of thromboprophylaxis with placebo or no treatment, or two (or more) methods of thromboprophylaxis. DATA COLLECTION AND ANALYSIS At least two review authors assessed trial eligibility, extracted data, assessed risk of bias, and judged certainty of evidence for selected critical outcomes (using GRADE). We conducted fixed-effect meta-analysis and reported data (all dichotomous) as summary risk ratios (RRs) with 95% confidence intervals (CIs). MAIN RESULTS Twenty-nine trials (involving 3839 women), overall at moderate to high risk of bias were included. Trials were conducted across the antenatal, peripartum and postnatal periods, with most in high-income countries. Interventions included types and regimens of heparin (low molecular weight heparin (LMWH) and unfractionated heparin (UFH)), hydroxyethyl starch (HES), and compression stockings or devices. Data were limited due to a small number of trials in comparisons and/or few or no events reported. All critical outcomes (assessed for comparisons of heparin versus no treatment/placebo, and LMWH versus UFH) were considered to have very low-certainty evidence, downgraded mainly for study limitations and imprecise effect estimates. Maternal death was not reported in most studies. Antenatal (± postnatal) prophylaxis For the primary outcomes symptomatic thromboembolic events pulmonary embolism (PE) and/or deep vein thrombosis (DVT), and the critical outcome of adverse effects sufficient to stop treatment, the evidence was very uncertain. Symptomatic thromboembolic events: - heparin versus no treatment/placebo (RR 0.39; 95% CI 0.08 to 1.98; 4 trials, 476 women; very low-certainty evidence); - LMWH versus UFH (RR 0.47; 95% CI 0.09 to 2.49; 4 trials, 404 women; very low-certainty evidence); Symptomatic PE: - heparin versus no treatment/placebo (RR 0.33; 95% CI 0.02 to 7.14; 3 trials, 187 women; very low-certainty evidence); - LMWH versus UFH (no events; 3 trials, 287 women); Symptomatic DVT: - heparin versus no treatment/placebo (RR 0.33; 95% CI 0.04 to 3.10; 4 trials, 227 women; very low-certainty evidence); - LMWH versus UFH (no events; 3 trials, 287 women); Adverse effects sufficient to stop treatment: - heparin versus no treatment/placebo (RR 0.49; 95% CI 0.05 to 5.31; 1 trial, 139 women; very low-certainty evidence); - LMWH versus UFH (RR 0.07; 95% CI 0.01 to 0.54; 2 trials, 226 women; very low-certainty evidence). Peripartum/postnatal prophylaxis Vaginal or caesarean birth When UFH and no treatment were compared, the effects on symptomatic thromboembolic events (RR 0.16; 95% CI 0.02 to 1.36; 1 trial, 210 women; very low-certainty evidence), symptomatic PE (RR 0.16; 95% CI 0.01 to 3.34; 1 trial, 210 women; very low-certainty evidence), and symptomatic DVT (RR 0.27; 95% CI 0.03 to 2.55; 1 trial, 210 women; very low-certainty evidence) were very uncertain. Maternal death and adverse effects sufficient to stop treatment were not reported. Caesarean birth Symptomatic thromboembolic events: - heparin versus no treatment/placebo (RR 1.30; 95% CI 0.39 to 4.27; 4 trials, 840 women; very low-certainty evidence); - LMWH versus UFH (RR 0.33; 95% CI 0.01 to 7.99; 3 trials, 217 women; very low-certainty evidence); Symptomatic PE: - heparin versus no treatment/placebo (RR 1.10; 95% CI 0.25 to 4.87; 4 trials, 840 women; very low-certainty evidence); - LMWH versus UFH (no events; 3 trials, 217 women); Symptomatic DVT: - heparin versus no treatment/placebo (RR 1.30; 95% CI 0.24 to 6.94; 5 trials, 1140 women; very low-certainty evidence); LMWH versus UFH (RR 0.33; 95% CI 0.01 to 7.99; 3 trials, 217 women; very low-certainty evidence); Maternal death: - heparin versus placebo (no events, 1 trial, 300 women); Adverse effects sufficient to stop treatment: - heparin versus placebo (no events; 1 trial, 140 women). Postnatal prophylaxis No events were reported for LMWH versus no treatment/placebo for: symptomatic thromboembolic events, symptomatic PE and symptomatic DVT (all 2 trials, 58 women), or maternal death (1 trial, 24 women). Adverse effects sufficient to stop treatment were not reported. We were unable to conduct subgroup analyses due to lack of data. Sensitivity analysis including the nine studies at low risk of bias did not impact overall findings. AUTHORS' CONCLUSIONS The evidence is very uncertain about benefits and harms of VTE thromboprophylaxis in women during pregnancy and the early postnatal period at increased risk of VTE. Further high-quality very large-scale randomised trials are needed to determine effects of currently used treatments in women with different VTE risk factors. As sufficiently large definitive trials are unlikely to be funded, secondary data analyses based on high-quality registry data are important.

Abstract
Antiphospholipid syndrome (APS) is a thromboinflammatory disease with a variety of clinical phenotypes. Primary thrombosis prophylaxis should take an individualized risk stratification approach. Moderate-intensity vitamin K antagonist such as warfarin remains the primary strategy for secondary thrombosis prophylaxis among APS patients, especially for patients with predominantly venous disease. For now, direct oral anti-coagulants should be avoided in most APS patients, especially those with history of arterial manifestations. Obstetric APS management should be tailored based on an individual patient's antiphospholipid antibody profile, and obstetric and thrombotic history. Pharmacological agents beyond anticoagulants may be considered for the management of microthrombotic and nonthrombotic manifestations of APS, although more data are needed. A relatively recent discovery in the area of APS pathogenesis is the implication of neutrophil extracellular traps in thrombin generation and initiation of inflammatory cascades. APS is a complex thromboinflammatory disease with a broad clinical spectrum. Personalized therapy according to an individual's unique thrombosis and obstetric risk should be advocated.

Abstract
BACKGROUND Antiphospholipid syndrome is associated with recurrent pregnancy loss. Low-molecular-weight heparin (LMWH) and/or aspirin (ASA) prophylaxis during pregnancy to prevent future loss is based on limited trial data with mixed results. OBJECTIVES Given the clinical equipoise, we sought to understand how patients and physicians navigate the decision-making process for use of LMWH and/or ASA in pregnancy. METHODS We interviewed 10 patients and 10 thrombosis physicians in Ottawa, Canada from January 2017 to March 2018. Patients who had ≥1 late pregnancy loss or ≥2 early losses and persistently positive antiphospholipid antibodies based on the revised Sapporo/Sydney criteria were identified in the a Thrombosis Clinic. Patients were also identified by the TIPPS Study screening logs of excluded patients. Data collection and analysis occurred iteratively, in keeping with constructivist grounded theory methodology. RESULTS Our analysis generated three themes, present across both patient and physician interviews, which captured a patient-led decision-making experience: (1) managing high stakes, (2) accepting uncertainty, and (3) focusing on safety. Patients and physicians acknowledged the high emotional burden and what was at stake: avoiding further pregnancy loss. Patients responded to their situation by taking action (i.e., using LMWH injections became a "ritual"), whereas physicians reacted by removing themselves from the final decision by "[leaving] it up to the patient." CONCLUSION Our findings should be considered when designing future research on studying the role for LMWH/ASA in this population, as it suggests that the perceived benefits of treatment go beyond improving pregnancy rates. Rather, patients described potential benefit from the process of taking action, even in the absence of a guaranteed good outcome.

Abstract
Intravenous immunoglobulin (IVIG) was first administered to humans in the 1980s. The mechanism of action of IVIG is still a subject of debate but the pharmacokinetics have been well characterized, albeit outside of pregnancy. IVIG has been used in pregnancy to treat several nonobstetrical and obstetrical-related conditions. However, current evidence suggests that IVIG use during pregnancy can be recommended for 1) in utero diagnosis of neonatal alloimmune thrombocytopenia; 2) gestational alloimmune liver disease; 3) hemolytic disease of the fetus and newborn for early-onset severe intrauterine disease; 4) antiphospholipid syndrome (APS) when refractory to or contraindicated to standard treatment, or in catastrophic antiphospholipid syndrome; and 5) immune thrombocytopenia when standard treatment is ineffective or rapid increase of platelet counts is needed. All recommendations are based on case series and cohort studies without randomized trials usually because of the rare prevalence of the conditions, the high incidence of adverse outcomes if left untreated, and ethical concerns. In contrast, IVIG therapy cannot be recommended for recurrent pregnancy loss, and the use of IVIG in subgroups of those with recurrent pregnancy loss requires further investigations. For non-obstetrical-related conditions, we recommend using IVIG as indicated for nonpregnant patients. In conclusion, the use of IVIG during pregnancy is an effective treatment in some obstetrical-related conditions with rare serious maternal side effects. However, the precise mechanisms of action and the long-term immunologic effects on the fetus and neonate are poorly understood and merit further investigations.

Abstract
The present study aimed to review relevant, randomized, controlled trials in order to determine the effects of aspirin and heparin treatment on recurrent spontaneous abortion (RSA) in women with antiphospholipid syndrome (APS). Previous relevant studies were identified using PubMed, Cochrane, Embase, CNKI, VANFUN and VIP by retrieving appropriate key words. Additionally, key relevant sources in the literature were reviewed and articles published before May 2019 were included. The 22 selected studies included 1,515 patients in the treatment group and 1,531 patients in the control group. These previous studies showed that heparin and aspirin significantly improved live birth rate when compared with treatments using intravenous immunoglobulin, aspirin alone or aspirin combined with prednisone. Moreover, heparin and aspirin greatly increased the birth weight compared with placebo and improved vaginal delivery relative to intravenous immunoglobulin. The gestational age at birth was significantly higher in the heparin and aspirin group compared with the placebo group and the incidence of intrauterine growth restriction was lower in the heparin and aspirin group compared with the placebo group. Furthermore, heparin and aspirin markedly reduced the incidence of miscarriage compared with the aspirin group and the placebo group, and the incidence of pre-eclampsia was lower in the heparin and aspirin group than the placebo group. Thus, heparin and aspirin could be further examined for the treatment of RSA in women with APS.

Abstract
Background: During pregnancy and in the postpartum period women are at increased risk of venous thromboembolism (VTE) owing to hypercoagulability and mechanical issues, as well as nonpregnancy conditions including inherited and acquired thrombophilia. Although guidelines exist for the use of thromboprophylaxis in this setting, there are differences in the specifics of the recommendations among expert societies. We assessed the current practice patterns of North American providers in the prevention of pregnancy-associated VTE in women with thrombophilia. Methods: A survey was created and distributed with case studies and questions addressing VTE prevention during the antepartum and postpartum periods. Results: Surveys were completed by 28% of adult providers queried, with broad geographic representation. There was consistent use of a prophylactic dose of low-molecular weight heparin (LMWH) ante- and postpartum for individuals with low-risk thrombophilia and past estrogen-provoked VTE but a lack of a consensus of anticoagulant (AC) use and dose in individuals with higher risk thrombophilia. There was variability in the dose selection and monitoring of AC when using induction versus spontaneous labor, with 47% of providers switching from LMWH to unfractionated heparin for those not having a scheduled delivery, and there were differences in the duration of postpartum prophylaxis based upon delivery mode. Conclusion: In this survey of North American experienced specialists' responses to a variety of commonly encountered scenarios of thrombophilia and pregnancy and the management of AC were not always consistent with published guidelines.

J Gynecol Obstet Hum Reprod 2020; 50:101974. [PMID: 33171281 DOI: 10.1016/j.jogoh.2020.101974] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 10/27/2020] [Accepted: 11/03/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND We performed a systematic review and meta-analysis to assess the efficacy and safety of heparin for preventing adverse obstetrical outcomes in pregnant women with antiphospholipid syndrome (APS). METHODS We reviewed randomized controlled trials from CENTRAL, EMBASE, MEDLINE, and Web of science (inception to November 5th 2019), and relevant article reference lists. Two reviewers independently screened and extracted data from trials investigating heparin, including Low Molecular Weight Heparin (LMWH) and unfractionated heparin (UFH) at any dose, associated or not with aspirin, compared to any comparator group in pregnant women with APS. Internal validity was assessed in duplicate using the Cochrane Risk of Bias tool. The strength of evidence was assessed in duplicate using the Grading of Recommendations Assessment, Development and Evaluation framework. Our primary outcome was live birth rate. Secondary outcomes included preeclampsia, preterm birth, intra-uterine growth restriction (IUGR) and thromboembolism. Safety outcomes included maternal or neonatal bleedings, heparin-induced thrombocytopenia and allergy. Subgroup analyses were conducted to explore heterogeneity. RESULTS From 2395 identified citations, 13 trials (1916 patients) met inclusion criteria. Heparin, associated or not with aspirin, significantly increased the rate of live birth compared to any comparator (RR 1.20; 95 % CI 1.09-1.33, I2 = 67 %, 1916 patients, low-certainty evidence). In subgroup analyses, LMWH and UFH were independently associated with greater rates of live birth: RR 1.15 (95 % CI 1.04-1.28, I2 = 71 %, 1684 patients, 9 trials) and RR 1.45 (95 % CI 1.16-1.81, I2 = 19 %, 149 patients, 4 trials) respectively. Heparin associated or not to aspirin, significantly decreased the rate of preeclampsia compared to any comparator (RR 0.32; 95 % CI 0.12-0.87, I2 = 0%, 465 patients, 8 trials) but was not associated with differential rates of preterm birth nor IUGR. Heparin was associated with minor bleeding (bruises, epistaxis): RR 2.58 (95 % CI 1.03-6.43, I2 = 16 %, 653 patients, 9 trials). No serious maternal or neonatal adverse events were reported in the included studies. CONCLUSIONS In pregnant women with APS, heparin, associated or not to aspirin, significantly improved the live birth rate compared to any comparator and decreased the risk of preeclampsia, without increasing maternal and neonatal severe morbidity.

Abstract
Obstetric antiphospholipid syndrome (APS) remains a clinical challenge for practitioners, with several controversial points that have not been answered so far. This Obstetric APS Task Force met on the 16th International Congress on Antiphospholipid Antibodies in Manchester, England, to discuss about treatment, diagnostic and clinical aspects of the disease. This report will address evidence-based medicine related to obstetric APS, including limitations on our current management, the relationship between antibodies against domain 1 of β2GPI and obstetric morbidity, hydroxychloroquine use in patients with obstetric APS and factors associated with thrombosis after obstetric APS. Finally, future directions for better understanding this complex condition are also reported by the Task Force coordinators.

Abstract
BACKGROUND Preeclampsia (PE) and intrauterine growth restriction (IUGR) are major causes of maternal and perinatal morbidity and mortality. Previous studies have shown that intervention with low-dose aspirin resulted in a reduction in the occurrence of preterm PE. However, no data are currently available on the effect of low-molecular-weight heparin (LMWH) for the prevention of pregnancy complications in women enrolled at first trimester screening. OBJECTIVE We aimed to assess the effectiveness of LMWH in the prevention of PE, IUGR, fetal death, and abruptio placentae in women classified as high risk based on their medical history and in women selected by first trimester screening of PE. Study -Design: This was a multicenter, randomized, open-label, parallel controlled trial in women without thrombophilia between 6.0 and 15.6 weeks of gestation. Inclusion criteria were severe PE or IUGR before 34 weeks of gestation and/or abruptio placentae or unexplained intrauterine death in a previous pregnancy; uterine artery mean pulsatility index Doppler >95th percentile and/or positive first trimester screening for PE. Pregnant women were randomly assigned to receive no intervention or LMWH until the 36th week of gestation. The primary composite outcome consisted of 1 or more of the following: development of PE, IUGR, abruptio placentae, and intrauterine fetal death. RESULTS A total of 278 pregnant women were randomly allocated to receive LMWH (n = 134) or no intervention (n = 144). Overall, 115 (41%) women experienced placental insufficiency complications, with no significant differences between the 2 arms: 50/144 (34.7%) in the LMWH arm and 43/134 (32%) in the control arm (p = 0.64, OR: 1.13, 95% CI: 0.68-1.85). CONCLUSION LMWH did not reduce the incidence of placenta-mediated complications either in women with previous adverse obstetric history without thrombophilia or in women selected by first trimester screening for PE. Based on these results, we cannot recommend the use of LMWH alone in women at risk of placental complications.

Abstract
Prior to 1983, several landmark reports prepared the stage for a detailed description of the Antiphospholipid (Hughes) syndrome (APS). Formerly depicted as lupus-like, APS exhibits a wide spectrum of symptoms that overlap with Sjogren's, Hashimoto, and other autoimmune diseases. In this review, we take a glimpse into the history of description of APS, discussing the events that led to its recognition as one of the most common autoimmune diseases and the enormous impact of that recognition in the rheumatology field.

Abstract
BACKGROUND Unexplained recurrent spontaneous abortion (URSA) frustrates women of childbearing age profoundly, and effective therapies are particularly important. OBJECTIVE To compare the efficacy of heparin combined with aspirin and aspirin alone for URSA. SEARCH STRATEGY Electronic databases (PubMed, Medline, Web of Science, Clinical key and Cochrane Library) were searched for relevant studies from database inception to August 2019. SELECTION CRITERIA Studies of women of childbearing age with at least two consecutive abortions were included. DATA COLLECTION AND ANALYSIS Relevant items were extracted, tabulated, and subjected to STATA for data analysis. Study women were divided into group A (taking heparin plus aspirin) and group B (taking aspirin alone). The primary outcome was the rate of live birth. MAIN RESULTS Women from eight randomized controlled trials were included: 493 in group A and 501 in group B. The number of live births was significantly higher in group A (P=0.003). The result remained the same in subgroup analysis by presence of antiphospholipid antibodies. Among women who had a live birth, gestational age at delivery tended to be older in group B (P=0.054). No differences in birthweight or intrauterine growth restriction were observed. Adverse effects were sporadically reported. CONCLUSION Among women with URSA, heparin combined with aspirin increased the live birth rate as compared with aspirin alone. There was a beneficial tendency of taking aspirin-only to prolong gestation week.

Abstract
BACKGROUND Aspirin and heparin are widely used as preventive strategy to reduce the high risk of recurrent pregnancy loss in women with antiphospholipid antibodies (aPL). This review supersedes a previous, out-of-date review that evaluated all potential therapies for preventing recurrent pregnancy loss in women with aPL. The current review focusses on a narrower scope because current clinical practice is restricted to using aspirin or heparins, or both for women with aPL in an attempt to reduce pregnancy complications. OBJECTIVES To assess the effects of aspirin or heparin, or both for improving pregnancy outcomes in women with persistent (on two separate occasions) aPL, either lupus anticoagulant (LAC), anticardiolipin (aCL) or aβ2-glycoprotein-I antibodies (aβ2GPI) or a combination, and recurrent pregnancy loss (two or more, which do not have to be consecutive). SEARCH METHODS We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (3 June 2019), and reference lists of retrieved studies. Where necessary, we attempted to contact trial authors. SELECTION CRITERIA Randomised, cluster-randomised and quasi-randomised controlled trials that assess the effects of aspirin, heparin (either low-molecular-weight heparin (LMWH) or unfractionated heparin (UFH]), or a combination of aspirin and heparin compared with no treatment, placebo or another, on pregnancy outcomes in women with persistent aPL and recurrent pregnancy loss were eligible. All treatment regimens were considered. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion criteria and risk of bias. Two review authors independently extracted data and checked them for accuracy and the certainty of the evidence was assessed using the GRADE approach. MAIN RESULTS Eleven studies (1672 women) met the inclusion criteria; nine randomised controlled trials and two quasi-RCTs. The studies were conducted in the USA, Canada, UK, China, New Zealand, Iraq and Egypt. One included trial involved 1015 women, all other included trials had considerably lower numbers of participants (i.e. 141 women or fewer). Some studies had high risk of selection and attrition bias, and many did not include sufficient information to judge the risk of reporting bias. Overall, the certainty of evidence is low to very low due to the small numbers of women in the studies and to the risk of bias. The dose and type of heparin and aspirin varied among studies. One study compared aspirin alone with placebo; no studies compared heparin alone with placebo and there were no trials that had a no treatment comparator arm during pregnancy; five studies explored the efficacy of heparin (either UFH or LMWH) combined with aspirin compared with aspirin alone; one trial compared LMWH with aspirin; two trials compared the combination of LMWH plus aspirin with the combination of UFH plus aspirin; two studies evaluated the combination of different doses of heparin combined with aspirin. All trials used aspirin at a low dose. Aspirin versus placebo We are very uncertain if aspirin has any effect on live birth compared to placebo (risk ratio (RR) 0.94, 95% confidence interval (CI) 0.71 to 1.25, 1 trial, 40 women, very low-certainty evidence). We are very uncertain if aspirin has any effect on the risk of pre-eclampsia, pregnancy loss, preterm delivery of a live infant, intrauterine growth restriction or adverse events in the child, compared to placebo. We are very uncertain if aspirin has any effect on adverse events (bleeding) in the mother compared with placebo (RR 1.29, 95% CI 0.60 to 2.77, 1 study, 40 women). The certainty of evidence for these outcomes is very low because of imprecision, due to the low numbers of women involved and the wide 95% CIs, and also because of risk of bias. Venous thromboembolism and arterial thromboembolism were not reported in the included studies. Heparin plus aspirin versus aspirin alone Heparin plus aspirin may increase the number of live births (RR 1.27, 95% CI 1.09 to 1.49, 5 studies, 1295 women, low-certainty evidence). We are uncertain if heparin plus aspirin has any effect on the risk of pre-eclampsia, preterm delivery of a live infant, or intrauterine growth restriction, compared with aspirin alone because of risk of bias and imprecision due to the low numbers of women involved and the wide 95% CIs. We are very uncertain if heparin plus aspirin has any effect on adverse events (bleeding) in the mother compared with aspirin alone (RR 1.65, 95% CI 0.19 to 14.03, 1 study, 31 women). No women in either the heparin plus aspirin group or the aspirin alone group had heparin-induced thrombocytopenia, allergic reactions, or venous or arterial thromboembolism. Similarly, no infants had congenital malformations. Heparin plus aspirin may reduce the risk of pregnancy loss (RR 0.48, 95% CI 0.32 to 0.71, 5 studies, 1295 women, low-certainty evidence). When comparing LMWH plus aspirin versus aspirin alone the pooled RR for live birth was 1.20 (95% CI 1.04 to 1.38, 3 trials, 1155 women). In the comparison of UFH plus aspirin versus aspirin alone, the RR for live birth was 1.74 (95% CI 1.28 to 2.35, 2 trials, 140 women). AUTHORS' CONCLUSIONS The combination of heparin (UFH or LMWH) plus aspirin during the course of pregnancy may increase live birth rate in women with persistent aPL when compared with aspirin treatment alone. The observed beneficial effect of heparin was driven by one large study in which LMWH plus aspirin was compared with aspirin alone. Adverse events were frequently not, or not uniformly, reported in the included studies. More research is needed in this area in order to further evaluate potential risks and benefits of this treatment strategy, especially among women with aPL and recurrent pregnancy loss, to gain consensus on the ideal prevention for recurrent pregnancy loss, based on a risk profile.

Abstract
Lupus anticoagulant (LA) has been associated with pregnancy complications and pregnancy loss. Identification of predictive factors could aid in deciding on therapeutic management. To identify risk factors for adverse pregnancy outcomes in high-risk women with persistently positive LA, we prospectively followed 82 women of childbearing age, of whom 23 had 40 pregnancies within the Vienna Lupus Anticoagulant and Thrombosis Study. Pregnancy complications occurred in 28/40 (70%) pregnancies, including 22 (55%) spontaneous abortions (<10th week of gestation [WOG]: n = 12, 10th to 24th WOG: n = 10) and 6 deliveries <34th WOG (15%, 3 due to severe preeclampsia/HELLP [hemolysis, elevated liver enzymes, and a low platelet count] syndrome, 3 due to placental insufficiency). One abortion was followed by catastrophic antiphospholipid syndrome. Neither a history of pregnancy complications nor of thrombosis, or prepregnancy antiphospholipid antibody levels were associated with adverse pregnancy outcomes. In logistic regression analysis, higher age was associated with a lower risk of adverse pregnancy outcome (per 5 years' increase: odds ratio [OR] = 0.41, 95% confidence interval [CI]: 0.19-0.87), a high Rosner index (index of circulating anticoagulant) predicted an increased risk (OR = 4.51, 95% CI: 1.08-18.93). Live birth rate was 15/28 (54%) in women on the combination of low-molecular-weight heparin and low-dose aspirin and 3/12 (25%) in those with no treatment or a single agent. We conclude that the risk of severe, even life-threatening pregnancy complications and adverse pregnancy outcomes is very high in women with persistent LA. A high Rosner index indicates an increased risk. Improved treatment options for women with persistently positive LA are urgently needed.
