Abstract
Antiphospholipid antibodies (APLAs) are primarily directed toward phospholipid-binding proteins and are responsible for thrombotic events. APLAs include anti-β2Glycoprotein I (anti-β2GPI), anticardiolipin (anti-CL) antibodies, and lupus anticoagulant. These antibodies are typical markers of antiphospholipid syndrome (APS) and are a part of its diagnostic criteria. Many data underline the presence of APLAs in other rheumatic diseases (e.g., systemic lupus erythematosus, systemic sclerosis, Sjögren's syndrome, rheumatoid arthritis and Behçet's disease). However, they are also detected in patients with cancer, infection, and neurological disorders. Furthermore, healthy individuals may be carriers of APLAs. Chronic asymptomatic APLAs presence is most common in the elderly and subjects with chronic diseases (including malignancies). Specific kinds of APLAs are considered markers of oncological progression. These antibodies occur in 6% of pregnant women (without diagnosed APS) and are related to many pregnancy complications. Of worth, various types of APLAs are reported to have different prothrombotic properties. The risk of thrombotic events in APLA-positive but clinically naïve patients raises many questions in clinical practice. This manuscript analyses various clinical situations and consequences of the APLAs' presence, particularly in patients without diagnosed APS. The prevalence, etiology, molecular background, and prothrombotic properties of numerous APLAs are broadly discussed. The new management approach in different clinical conditions and organ complications is present in the context of recent recommendations. Discussed data underlines that adequate and timely introduced thromboprophylaxis can decrease the risk of thrombus formation and prevent increased morbidity.

Abstract
Introduction The endometrial immune profiling is an innovative approach based on the analysis of the local immune reaction occurring in the endometrium at the time of the embryo implantation. By documenting the local immune activation during the period of uterine receptivity, we aim to detect and correct potential imbalances before and at the very beginning of placentation. The main objective of the study was to analyze in women with a history of repeated pregnancy loss (RPL) the association of personalized strategies based on immune dysregulations with live birth rates. The secondary objective was to highlight the main prognostic factors for live births. Methods This is an observational retrospective analysis of 104 patients with RPL, included between January 2012 and December 2019. Inclusion criteria included a spontaneous fertility with at least three miscarriages, an assessment including a three-dimension ultrasound scan, an endometrial biopsy for uterine immune profiling and a follow-up over at least 6 months with personalized care if indicated after the complete assessment. We defined as a success if the patients had a live birth after the suggested plan, as a failure if the patient either did not get pregnant or experienced a new miscarriage after the targeted therapies. Results Uterine immune profiling was the only exploration to be significantly associated with a higher live birth rate (LBR) if a dysregulation was identified and treated accordingly (55% vs 45%, p=0.01). On the contrary, an absence of local dysregulation (resulting in an apparently balanced immune environment) was associated with a higher risk of a new miscarriage, suggesting that the cause inducing RPL still needed to be identified. Independently of age and AMH level, dysregulated immune profile is significatively associated with 3 times higher LBR than a non-deregulated profile (OR=3.4 CI 95%1.27-9.84) or five times in case of an overactive profile treated by immunotherapy (OR=5 CI 95% 1.65-16.5). The usage of ART was significantly associated with lower LBR regardless of the presence of a subfertility factor (p=0.012). Personalization of medical care using natural cycle or simple hormonal stimulation is associated with a significantly higher LBR than personalization including ART treatments regardless of maternal age and AMH level (OR= 2.9 CI 95% 1.03-8.88). Conclusion Our study suggests that some endometrial immune profiles with targeted management of RPL are associated with a higher rate of LBR. ART may be negatively associated with LBR.

Abstract
Antiphospholipid syndrome is defined by the presence of thrombosis and/or obstetrical adverse events (≥3 recurrent early miscarriage or fetal death or a prematurity<34 weeks of gestation) associated with persistent antiphospholipid antibodies. The pregnancy outcome has been improved by the conventional treatment (aspirin 100mg/day with low molecular weight heparin [LMWH] from 30 to 75% of uncomplicated pregnancies. In PROMISSE study, 19% of pregnancies had at least one obstetrical adverse event despite treatment (maternal, fetal or neonatal complications) in relation with APS. In the European registry of babies born from APS mothers, maternal and foetal adverse events were observed in 13% of cases, with prematurity in 14% despite treatment. The presence of lupus erythematosus, a history of thrombosis, presence of lupus anticoagulant and APL triple positivity are considered as factors associated with unfavorable obstetrical outcome. Hydroxychloroquine (HCQ) has anti-inflammatory and anti-thrombotic properties. Studies in vitro have shown that HCQ is able to restore the placental expression of Annexin V, which has an anticoagulant effect and to prevent the placental injury induced by APL. HCQ used for lupus erythematosus decrease the thrombotic risk and its value for thrombotic APS has been raised in an open labelled French study. In European retrospective study, the addition of HCQ to conventional treatment improved refractory obstetrical APS. Its use during the pregnancy of patients with lupus erythematosus, the evidence of good safety during the pregnancy and follow-up of children born to mothers exposed to HCQ demonstrate an overall good safety profile for mothers and the fetus. This clinical trial is designed to assess the interest of the addition of hydroxychloroquine to conventional treatment in APS during the pregnancy.

Abstract
Most investigators currently advocate prophylactic-dose heparin plus low-dose aspirin as the preferred treatment of otherwise healthy women with obstetric antiphospholipid syndrome, whilst women with a history of vascular thrombosis alone or associated with pregnancy morbidity are usually treated with therapeutic heparin doses in association with low-dose aspirin in an attempt to prevent both thrombosis and pregnancy morbidity. However, the protocols outlined above fail in about 20 % of pregnant women with antiphospholipid syndrome. Identifying risk factors associated with pregnancy failure when conventional therapies are utilized is an important step in establishing guidelines to manage these high-risk patients. Some clinical and laboratory risk factors have been found to be related to maternal-foetal complications in pregnant women on conventional therapy. However, the most efficacious treatments to administer to high-risk antiphospholipid syndrome women in addition to conventional therapy in order to avoid pregnancy complications are as yet unestablished. This is a comprehensive review on this topic and an invitation to participate in a multicentre study in order to identify the best additional treatments to be used in this subset of antiphospholipid syndrome patients.

Abstract
Obstetrical APS is defined by thrombosis and/or obstetrical morbidity associated with persistent antiphospholipid antibodies. The aspirin and low molecular weighted heparin combination dramatically improved obstetrical outcome in APS patients. Several factors could be associated with obstetrical prognosis, as previous history of thrombosis, associated SLE, the presence of lupus anticoagulant and triple positivity of antiphospholipid antibodies. Obstetrical APS with isolated recurrent miscarriages is mostly associated with isolated anticardiolipids antibodies and have better obstetrical outcome. The pregnancy loss despite aspirin and heparin combination define the refractory obstetrical APS, and the prevalence could be estimated to 20-39%. Several other treatments have been used in small and open labeled studies, as steroids, intravenous immunoglobulins, plasma exchanges and hydroxychloroquine to improve the obstetrical outcome. Some other drugs as eculizumab and statins could also have physiopathological rational, but studies are necessary to define the place of these various drugs.

Abstract
The catastrophic antiphospholipid syndrome (CAPS) develops in at least 1% of patients with antiphospholipid syndrome, either primary or associated with systemic lupus erythematosus. CAPS reveals the antiphospholipid syndrome in about 50% of cases. The CAPS is characterized by rapidly-progressive widespread thromboses mainly affecting the microvasculature in the presence of antiphospholipid antibodies. In a few days, the patients develop multiorgan failure with renal insufficiency with severe hypertension, pulmonary, cerebral, cardiac, digestive and/or cutaneous involvement. The vital prognosis is frequently engaged. CAPS is often precipitated by infectious diseases, surgical procedures and/or withdrawal or modification of the anticoagulation. CAPS overall mortality rate has decreased and is currently below 30%. The main differential diagnoses are other thrombotic microangiopathies, and heparin-induced thrombocytopenia. The treatment of CAPS consists of the association of anticoagulation and steroids, plus plasma exchange and/or intravenous immunoglobulins. Cyclophosphamide is added only in patients with active systemic lupus erythematosus. The potential contribution of some additional therapies (rituximab, eculizumab or sirolimus) needs to be assessed. The prevention of CAPS is essential and is based upon the adequate management of the perioperative period when surgery cannot be avoided, the prompt treatment and the prevention with immunization of infections and the education of patients with antiphospholipid syndrome, especially for the management of oral anticoagulants.

Abstract
Acquired and inherited thrombophilia have both been reported to be associated with an increased risk of obstetric complications in early or later stages of pregnancy. Annexin A2 (ANXA2) is strongly expressed in vascular and placental tissues and plays a crucial role in fibrinolysis. The aim of the present study was to evaluate the prevalence of antibodies directed against ANXA2 in patients with recurrent miscarriage or obstetric complications. Anti-ANXA2 antibodies (aANXA2) were detected by ELISA in the sera from 46 women with obstetric morbidity, mainly recurrent miscarriage. The cut-off value for positivity was defined as 3 standard deviations above the mean optical density (OD) obtained in the sera from 42 female blood donors. The prevalence of aANXA2 in patients and healthy individuals was 15.2% and 2.3%, respectively. A statistically significant difference was observed between the 2 groups in terms of aANXA2 IgG titers (p=0.01). The highest aANXA2 levels were observed in sera from 2 patients with recurrent miscarriage and one patient with preeclampsia. aANXA2 could play a role in thrombotic mechanisms leading to recurrent pregnancy loss and placental vascular disease. Further studies are needed to determine whether ANXA2 is critical for maintenance of placental integrity.

Abstract
OBJECTIVE The aim of this article is to assess the predictive value of second trimester mean uterine artery Doppler pulsatility index (mUtA PI) for pregnancy complications in women with systemic lupus erythematosus (SLE). METHODS Cohort study of consecutive pregnancies complicated with SLE during a period of 12 years is used. SLE diagnosis was made before pregnancy. mUtA PI was measured between 23 + 0 and 26 + 6 weeks' gestation. Pregnancy and neonatal outcomes were collected. Small for gestational age (SGA) was defined as birth weight <10th percentile. Adverse pregnancy outcome (APO) was defined as one of the following: pre-eclampsia (PE), SGA, placental abruption, stillbirth, or neonatal death. Differential diagnosis between PE and renal flare was made according to SLE-disease activity index. RESULTS There are 70 pregnancies in 64 women. PE was observed in four cases (6%), SGA in five cases (7%), and APO in seven cases (10%). mUtA PI showed a sensitivity and a specificity of 1.0 (95% CI 0.5-1.0) and 1.0 (95% CI 0.95-1.0) for PE, 0.40 (95% CI 0.12-0.77) and 0.97 (95% CI 0.89-0.99) for SGA, and 0.57 (95% CI 0.25-0.84) and 1.0 (95% CI 0.94-1.0) for APO, respectively. CONCLUSION Our findings suggest that uterine artery Doppler is confirmed to be a high sensitivity and a high specificity test for predicting PE even in SLE patients.

Abstract
Liver disease can be observed in pregnant women whether or not related to pregnancy. Liver disorders can be revealed by pruritus, vomiting, jaundice or abnormal liver blood tests during pregnancy. These liver manifestations can lead to the diagnosis of liver disease specifically associated to pregnancy as intrahepatic pregnancy, intrahepatic cholestasis of pregnancy, Hyperemesis gravidarum, acute fatty liver of pregnancy and preeclampsia-induced liver injury. Pregnancy may also be a risk factor for other liver diseases coincident with pregnancy as viral hepatitis, thrombosis, drug toxicity or gallstone. Finally, pre-existing liver disease must be taken into account given the risk of fœto-maternal transmission risk as well as the risk of decompensation of underlying cirrhosis secondary to the hemodynamic changes caused by pregnancy. The aim of this revue is to perform an update on the various situations that can be observed, the principles of management of these liver diseases, in order to reduce the risk of complications and to ensure the best maternal and fetal prognosis.

Abstract
Fertility is not impaired in systemic lupus erythematosus or antiphospholipid syndrome, but, similarly to the general population, these patients may undergo in vitro fertilization. This type of treatment increases the risk of lupus flare, thrombosis, and ovarian hyperstimulation syndrome. This review will focus on in vitro fertilization in systemic lupus erythematosus or antiphospholipid syndrome. Literature data are relatively scant with only 3 reported studies. The first one included 17 patients and 63 cycles of induction ovulation/in vitro fertilization leading to 25 % of lupus flare, no thrombosis, and 3 % of ovarian hyperstimulation syndrome. The second study included 10 patients and 40 cycles of in vitro fertilization showing 31 % of lupus flare, no thrombosis and no ovarian hyperstimulation syndrome. The last one included 34 patients and 83 procedures of in vitro fertilization leading to 8 % of flares, 5 % of thrombosis and no ovarian hyperstimulation syndrome. Interestingly, in this last study, half of the complications were explained by poor adherence to treatment. These data are reassuring but it is important to remember that in vitro fertilization should be scheduled and carefully supervised in the same way as the high-risk pregnancies occurring in these patients.

Abstract
Pregnancy loss is a general term including distinct well-defined entities: early miscarriage, late miscarriage, and stillbirth. It is important to clarify fetal loss circumstances to guide the diagnostic assessment of this issue. Etiological considerations in the presence of a fetal loss are very important to find the causes where a treatment exists and is efficient. The aim is also to explain to the couple, very affected by the event, the reason of the fetal loss and the potential risk of recurrence in a future pregnancy. In recent years, international guidelines changed and assessment of familial thrombophilia seems to be useless in this context. Feedback of the investigations will be better in a preconception consultation and multidisciplinary management of these couples is important for both therapeutic and psychological cares.

Abstract
The use of the conventional APS treatment (the combination of low-dose aspirin and LMWH) dramatically improved the obstetrical prognosis in primary obstetrical APS (OAPS). The persistence of adverse pregnancy outcome raises the need to find other drugs to improve obstetrical outcome. Hydroxychloroquine is widely used in patients with various autoimmune diseases, particularly SLE. Antimalarials have many anti-inflammatory, anti-aggregant and immune-regulatory properties: they inhibit phospholipase activity, stabilize lysosomal membranes, block the production of several pro-inflammatory cytokines and, in addition, impair complement-dependent antigen-antibody reactions. There is ample evidence of protective effects of hydroxychloroquine in OAPS similar to the situation in SLE arising from in vitro studies of pathophysiological working mechanism of hydroxychloroquine. However, the clinical data on the use of hydroxychloroquine in primary APS are lacking and prospective studies are necessary.

Abstract
OBJECTIVE The objective of our study was to compare treatment-based obstetrical outcomes in women with either thrombotic or obstetrical antiphospholipid syndrome (APS). MATERIALS AND METHODS This was a historical cohort study conducted between 1998 and 2009 in 23 patients who had a total of 83 pregnancies. The syndrome was diagnosed using the 2006 Sapporo criteria. RESULTS Thirty-one of these 83 pregnancies were valid before the diagnosis was made. A live infant was born in 22% of them, the infant being small for gestational age in 26% of cases. The fetus died in utero in a further 26% of cases. Pregnancies were subdivided into 2 groups depending on whether the initial event leading to APS diagnosis was obstetrical or thrombotic. Treatment (aspirin and low molecular weight heparin) was based on this classification: the latter was given in a curative dose for thrombotic events, in a preventive dose for obstetrical events. No fetal loss was observed when treatment was administered according to the protocol. Nevertheless, 20% of the pregnancies with obstetrical APS were complicated by smallness for gestational age and only 38% of the infants were live births. More than 87% of the thrombotic forms treated were free of complications and led to birth of a living child. CONCLUSION Appropriate treatment appears to improve the prognosis for pregnancies in patients with APS. These patients are nevertheless at increased risk of an obstetrical event and require close monitoring, especially in obstetrical manifestations, which appear to have a poorer prognosis. Multidisciplinary follow-up by an experienced team is essential.

Abstract
Obstetric antiphospholipid syndrome (APS) is now being recognized as a distinct entity from vascular APS. Pregnancy morbidity includes >3 consecutive and spontaneous early miscarriages before 10weeks of gestation; at least one unexplained fetal death after the 10th week of gestation of a morphologically normal fetus; a premature birth before the 34th week of gestation of a normal neonate due to eclampsia or severe pre-eclampsia or placental insufficiency. It is not well understood how antiphospholipid antibodies (aPLs), beyond their diagnostic and prognostic role, contribute to pregnancy manifestations. Indeed aPL-mediated thrombotic events cannot explain the obstetric manifestations and additional pathogenic mechanisms, such as a placental aPL mediated complement activation and a direct effect of aPLs on placental development, have been reported. Still debated is the possible association between aPLs and infertility and the effect of maternal autoantibodies on non-vascular manifestations in the babies. Combination of low dose aspirin and unfractionated or low molecular weight heparin is the effective treatment in most of the cases. However, pregnancy complications, in spite of this therapy, can occur in up to 20% of the patients. Novel alternative therapies able to abrogate the aPL pathogenic action either by interfering with aPL binding at the placental level or by inhibiting the aPL-mediated detrimental effect are under active investigation.

Abstract
Antiphospholipid syndrome (APS) is an acquired thrombophilia with clinical manifestations associated with the presence of antiphospholipid antibodies (aPL) in patient plasma. Obstetrical APS is a complex entity that may affect both mother and fetus throughout the entire pregnancy with high morbidity. Clinical complications are as various as recurrent fetal losses, stillbirth, intrauterine growth restriction (IUGR), and preeclampsia. Pathogenesis of aPL targets trophoblastic cells directly, mainly via proapoptotic, proinflammatory mechanisms, and uncontrolled immunomodulatory responses. Actual first-line treatment is limited to low-dose aspirin (LDA) and low-molecular weight heparin (LMWH) and still failed in 30% of the cases. APS pregnancies should be a major field in obstetrical research, and new therapeutics are still in progress.
