Abstract
Abstract
Background
Systemic lupus erythematosus is a multifaceted chronic relapsing autoimmune disease of unknown etiology. The disease has always been a serious diagnosis in women being a multisystem pathology that is classically encountered during the childbearing age posing serious systemic comorbidities with a potential impact on the functional performance, psychosocial status, and survival. In this article, we review critical issues related to the decision to conceive in female with lupus highlighting the impact of the diagnosis and disease activity status on the mother and the fetus, attempting to suggest a consensus to guide safe decision making for pregnancy with SLE.
Main body
The pleomorphic dysregulated immune nature of lupus in the presence of uncontrolled disease carries a higher risk of complicated pregnancy. Therefore, SLE pregnancies should be well planned and are usually encouraged if the disease is inactive (at least 6 months prior to conception) to ensure immune quiescence towards a safer outcome.
Conclusion
With the proper implementation of preconception counseling strategy, choice of the correct timing of conception, close monitoring of SLE flares with tight control, and the appreciation of the value of multidisciplinary management to best practice most young women with SLE can carry on successful pregnancies with favorable outcome.

Preparing for Pregnancy in Women with Systemic Lupus Erythematosus—A Multidisciplinary Approach. Medicina (B Aires) 2022; 58:medicina58101371. [DOI: 10.3390/medicina58101371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 09/22/2022] [Accepted: 09/23/2022] [Indexed: 11/17/2022] Open
Abstract
Pregnancy is one of the most challenging processes the human body is exposed to: the healthy mother can carry to term a genetically different new-born, while her immune system adapts to tolerate this new status and avoids rejection. In autoimmune disorders, motherhood is even more challenging, with additional medical counselling, mother care, and foetus development checks being necessary. While the aspects of supplementary mother care and pregnancy progress tracking are associated with well-established medical procedures and protocols, counselling, be it pre- or post-conception, is still underestimated and scarcely applied. Indeed, over the past decades, medical counselling for this particular population has changed significantly, but from a healthcare’s provider point of view, more is required to ensure a smooth, controllable pregnancy evolution. One of the most frequent autoimmune diseases affecting young females during their fertile years is Systemic Lupus Erythematosus (SLE). Like other heterogenous diseases, it exposes the mother to severe, organ-threatening complications and unpredictable evolution. Both the disease and its treatment can significantly affect the mother’s willingness to engage in a potentially risky pregnancy, as well as the likeliness to carry it to term without any impairments. A good collaboration between the patient’s rheumatologist and obstetrician is therefore mandatory in order to: (a) allow the mother to make an informed decision on pursuing with the pregnancy; (b) ensure a perfect synchronization between pregnancy terms and treatment; and (c) avoid or minimize potential complications. The best approach to achieve these outcomes is pregnancy planning. Moreover, knowing one desired prerequisite for a successful pregnancy evolution in SLE mothers is a stable, inactive, quiescent disease for at least six months prior to conception, planning becomes more than a recommended procedure. One particular aspect that requires attention before conception is the treatment scheme applied before delivery as autoantibodies can influence significantly the course of pregnancy. In this view, future SLE mothers should ideally benefit from preconception counselling within their agreed care pathway. A multidisciplinary team including at least the rheumatologist and obstetrician should be employed throughout the pregnancy, to decide on the appropriate timing of conception and compatible medication with respect to disease activity, as well as to monitor organ involvement and foetus development progress.

Abstract
Systemic lupus erythematosus (SLE) is a systemic autoimmune inflammatory disease that predominantly affects women of childbearing age and results in various adverse pregnancy outcomes (APOs). Pregnancy was formerly discouraged in patients with SLE because of unstable disease activity during the gestation period, increased thrombosis risk, severe organ damage, and inevitable side effects of immunosuppressive agents. Currently, most patients with SLE have successful pregnancies due to preconception counselling, strict monitoring, and improved therapy with minimised complications for both the mother and foetus. Hydroxychloroquine (HCQ) is extensively used and is beneficial for improving pregnancy outcomes. However, pregnant women with SLE have a high-risk of APOs, such as disease flare, preterm birth, intrauterine growth restriction (IUGR), preeclampsia, and pregnancy loss. Better understanding of the changes in maternal immunity and serum biomarkers, as well as their relationships with SLE-related APOs progression, would facilitate the investigation of molecular mechanisms for triggering and ameliorating APOs. Furthermore, it would enable us to explore and develop novel and effective therapeutic strategies to prevent disease activation. Therefore, this review briefly introduces the interaction between pregnancy outcomes and SLE, elucidates pathophysiological and immunological changes during SLE pregnancy. Furthermore, this review systematically expounds on the effective predictors of APOs and the molecular mechanisms underlying the SLE-related APOs to provide a solid foundation for the advanced management of lupus pregnancy.

Abstract
Background Systemic lupus erythematosus (SLE) can cause placental dysfunctions, which may result in pregnancy complications. Long noncoding RNAs (lncRNAs) are actively involved in the regulation of immune responses during pregnancy. The present study aimed to determine the lncRNA expression profiles in placentas from women with SLE to gain new insights into the underlying molecular mechanisms in SLE pregnancies. Methods RNA sequencing (RNA-seq) analysis was performed to identify SLE-dysregulated lncRNAs and mRNAs in placentas from women with SLE and normal full-term (NT) pregnancies. Bioinformatics analysis was conducted to predict the biological functions of these SLE-dysregulated lncRNAs and mRNAs. Results RNA-seq analysis identified 52 dysregulated lncRNAs in SLE placentas, including 37 that were upregulated and 15 downregulated. Additional 130 SLE-dysregulated mRNAs were discovered, including 122 upregulated and 8 downregulated. Bioinformatics analysis revealed that SLE-dysregulated genes were associated with biological functions and gene networks, such as regulation of type I interferon-mediated signaling pathway, response to hypoxia, regulation of MAPK (mitogen-activated protein kinase) cascade, response to steroid hormone, complement and coagulation cascades, and Th1 and Th2 cell differentiation. Conclusions This is the first report of the lncRNA profiles in placentas from SLE pregnancies. These results suggest that the aberrant expression and the potential regulatory function of lncRNAs in placentas may play comprehensive roles in the pathogenesis of SLE pregnancies. SLE-dysregulated lncRNAs may potentially serve as biomarkers for SLE. Supplementary Information The online version contains supplementary material available at 10.1186/s13075-022-02825-7.

Abstract
Acquired factor VIII deficiency is a bleeding disorder caused by the presence of autoantibodies against clotting factor VIII. We report a case of a 24-year-old pregnant woman who presented with gross hematuria secondary to acquired factor VIII deficiency in the presence of a previously undiagnosed connective tissue disease. This article includes a literature review of pregnancy-related cases of acquired factor VIII deficiency. We also reviewed various therapeutic approaches for the management of the acquired factor inhibitor which include achieving hemostasis and elimination of the inhibitor via immunosuppressive agents. This case report describes the rare presentation of acquired factor VIII deficiency related to pregnancy and highlights the importance of considering a factor VIII inhibitor in the differential diagnosis of patients who present with bleeding and prolonged PTT during the peripartum and postpartum periods.

Abstract
BACKGROUND Neonatal lupus erythematosus is an autoimmune disease acquired during fetal life as a result of transplacental passage of maternal anti-Sjögren's-syndrome-related antigen A (anti-SSA/Ro), anti-Sjögren's-syndrome-related antigen B (anti-SSB/La) or anti-U1 ribonucleoprotein (anti-U1-RNP) antinuclear autoantibodies. CONTENTS Clinical manifestations include skin lesions, congenital heart block, hepatobiliary involvement and cytopenias. Most of the disorders disappear spontaneously after clearance of maternal antibodies. Cardiac symptoms, however, are not self-resolving and often pacemaker implantation is required. Diagnosis is based on clinical presentation and the presence of typical antibodies in the mother's or infant's serum. OUTLOOK Neonatal lupus erythematosus may develop in children born to anti-SSA/Ro or anti-SSB/La women with various systemic connective tissue diseases. However, in half of the cases, the mother is asymptomatic, which may delay the diagnosis and have negative impact on the child's prognosis. Testing for antinuclear antibodies should be considered in every pregnant woman since early treatment with hydroxychloroquine or intravenous immunoglobulin (IVIG) has proven to be effective in preventing congenital heart block.

Abstract
OBJECTIVES Systemic lupus erythematosus (SLE) is a chronic illness that often affects women of reproductive age. The objectives of this article are to review the impact of SLE on pregnancy and current management strategies, including commonly used therapies. METHODS We conducted a review of available literature on the clinical course of SLE, diagnosis, management and pregnancy complications. RESULTS SLE has a variable clinical course characterized by flares and periods of remission and can present unique challenges in the management of obstetric patients. Pregnancy in patients with SLE is associated with multiple risks, including fetal loss, preterm birth, fetal growth restriction, and hypertensive disease. With advancements in disease treatment, many women have favorable pregnancy outcomes, but appropriate preconception counseling and disease management remain important tools in reducing complications. CONCLUSION Given the implications SLE can have on women of reproductive age and in pregnancy, understanding the disease course and management is important in order to optimize pregnancy outcomes.

Abstract
The intricacy of the maternal immune system arises from its ability to prevent a maternal immune response against a semi-allogenic fetus, while protecting the mother against harmful pathogens. However, these immunological adaptations may also make pregnant women vulnerable to developing adverse complications from respiratory viral infections. While the influenza and SARS pandemics support this theory, there is less certainty regarding the clinical impact of SARS-CoV-2 in pregnancy. In the current COVID-19 pandemic, vaccine development is key to public preventative strategies. Whilst most viral vaccines are able to induce a seroprotective antibody response, in some high-risk individuals this may not correlate with clinical protection. Some studies have shown that factors such as age, gender, and chronic illnesses can reduce their effectiveness and in this review, we discuss how pregnancy may affect the efficacy and immunogenicity of vaccines. We present literature to support the hypothesis that pregnant women are more susceptible to respiratory viral infections and may not respond to vaccines as effectively. In particular, we focus on the clinical implications of important respiratory viral infections such as influenza during pregnancy, and the pregnancy induced alterations in important leukocytes such as TFH, cTFH and B cells, which play an important role in generating long-lasting and high-affinity antibodies. Finally, we review how this may affect the efficacy of vaccines against influenza in pregnancy and highlight areas that require further research.

Abstract
Preeclampsia is characterized by blood pressure greater than 140/90 mmHg in the second half of pregnancy. This disease is a major contributor to preterm and low birth weight babies. The early delivery of the baby, which becomes necessary for maintaining maternal well-being, makes preeclampsia the leading cause for preterm labor and infant mortality and morbidity. Currently, there is no cure for this pregnancy disorder. The current clinical management of PE is hydralazine with labetalol and magnesium sulfate to slow disease progression and prevent maternal seizure, and hopefully prolong the pregnancy. This review will highlight factors implicated in the pathophysiology of preeclampsia and current treatments for the management of this disease.

Abstract
Listeria monocytogenes has a well-characterized ability to cross the placental barrier, resulting in spontaneous abortion and fetal infections. However, the mechanisms resulting in infection-associated abortion are not fully understood. In this study, we demonstrate that the dephosphorylation of MAPK family proteins caused by L. monocytogenes infection of trophoblast giant (TG) cells, which are placental immune cells, contributes to infectious abortion. Dephosphorylation of c-Jun, p38, and ERK1/2 was observed in infected TG cells, causing the downregulation of cytoprotective heme oxygenase (HO)-1. Blocking the dephosphorylation of proteins, including MAPK family proteins, inhibited the decrease in HO-1 expression. Treatment with MAPK inhibitors inhibited bacterial internalization into TG cells. Moreover, Toll-like receptor 2 involved in the expression of MAPK family proteins. Infection with a listeriolysin O-deleted mutant impaired dephosphorylation of MAPK family proteins in TG cells and did not induce infectious abortion in a mouse model. These results suggest that inactivation of the MAPK pathway by L. monocytogenes induces TG cell death and causes infectious abortion.
