Background: Systemic sclerosis (SSc) is a chronic immune-mediated connective tissue disease that can affect women of childbearing age. The long-term outcomes of their offspring remain poorly explored. Aim of this study was to detail the neurodevelopmental profile of children born to SSc mothers., Methods: Twenty children (mean age: 96 ± 4.32 months; 10 males) born to SSc mothers were enrolled. We collected data on clinical history, neurological examination, cognitive profile and adaptive behavior in all subjects. According to the chronological age, we also investigated quality of life, behavioral characteristics, psychological functioning and self-image., Results: All the children had normal neurological examination, cognitive profile and adaptive functioning, except for one (5 %) who suffered from Autism Spectrum Disorder. An important discrepancy was observed between parental and child opinion regarding the perception of quality of life, more compromised in the latter. We documented a risk for internalizing behavioral problems in 2 cases (10 %), for externalizing problems in 3 (15 %), for both in 1 (5 %) and for social and out-of-school activities in 5 (25 %). As regards psychological functioning, evaluated in 11 children, three (28 %) were at risk for anxiety, 1 (9 %) for depressive disorders and other 4 (36 %) for somatic disturbances. Emotional fragility and poor competence in metabolizing one's emotional experiences were observed in 9 out of the 13 subjects assessed (70 %)., Conclusions: Children born to SSc women exhibit normal cognitive and adaptive abilities but an increased vulnerability to psychopathological problems and fragility in social functioning. These observations might reflect that children need to feel mature to accept maternal chronic disease that, in turn, may hinder support for offspring's social and emotional development., Competing Interests: Declaration of competing interest Author MGL has received research support from GILS.

In antiphospholipid syndrome (APS), the risk of clinical manifestations increases with higher titers of antiphospholipid antibodies (aPL). Despite the adoption of aPL titers in the classification approach to aPL-positive subjects, the value of longitudinal monitoring of those titers in the follow-up is still debated, being well studied only in systemic lupus erythematosus (SLE). The literature suggests that the rate of aPL positivity decreases during follow-up in primary APS, estimating that seroconversion occurs in between 8.9 and 59% of patients over time. Negativisation of aPL occurs more frequently in asymptomatic aPL carriers than in patients with full-blown APS as well as in subjects with single aPL positivity or low aPL antibody titers. In patients with SLE, aPL typically behave fluctuating from positive to negative and back again in the course of follow-up. The few studies assessing the longitudinal course of aPL positivity with no associated systemic connective tissue disease reported a progressive decrement of aPL titers over time, in particular of antibodies against β2 glycoprotein I (antiβ2GPI) and cardiolipin (aCL) of IgG isotype. After a thrombotic event, aPL titers tend to decrease, as emerged from cohorts of both primary and secondary APS. Hydroxychloroquine has been identified as the most effective pharmacological agent to reduce aPL titers, with multiple studies demonstrating a parallel reduction in thrombosis rate. This review addresses available evidence on the significance of aPL titer fluctuation from clinical, therapeutic and pathogenic perspectives., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Immuno-mediated inflammatory diseases (IMIDs) such as rheumatoid arthritis, spondyloarthritis, and inflammatory bowel disease are characterised by pathophysiological mechanisms wherein the immune system erroneously targets the body's own tissues. This review explores the heightened vulnerability of women with IMIDs, influenced by hormonal modulators like estrogen and progesterone. The challenges this poses are multifaceted, encompassing the impact of active disease and medical treatments throughout life stages, including family planning, fertility, and menopause. From the perspectives of rheumatologists and gastroenterologists, we review current management strategies and underscore the need for a multidisciplinary and life-cycle approach to healthcare for women with IMIDs., Competing Interests: Declaration of Competing Interest L.A. and M.P. received an honorarium from Pfizer in connection with the development of this manuscript.

Background: Complement levels have been proposed as candidate biomarkers of disease activity and obstetric risk in systemic lupus erythematosus (SLE) pregnancies, but their reliability has been questioned due to the physiologic fluctuations of complement during gestation. Thus, this network meta-analysis aimed at assessing the clinical significance of complement fluctuations in lupus pregnant women., Methods: Corresponding authors of 19 studies meeting inclusion criteria were invited to contribute with additional data including C3 and C4 levels [before pregnancy, at conception, in every trimester (T) and 3 months after delivery]; data were pooled together in a network meta-analysis., Results: A total of 532 lupus women from four studies were included in the analysis. In SLE women, C3 and C4 increased progressively during gestation: levels remained stable during T1 and peaked in T2 to decrease in T3. Patients with previous lupus nephritis (LN) and those who experienced flares during pregnancy had significantly lower mean levels of C3 and C4 at all timepoints. The lowest levels of complement were observed, particularly during T1, in patients with LN and gestational flare. Both reduction and the lack of increase of C3 and C4 levels at T1 versus conception were associated with gestational flares, particularly in LN patients. Pregnancies with flare had a statistically significant higher rate of maternal and fetal complications(60% versus 50.3%; p = 0.03)., Conclusions: Low complement levels, particularly in T1, were associated with a higher frequency of gestational flare. Either reduction or smaller increase of C3 and/or C4 levels, even within normal range, might predict flares especially in early gestation., Competing Interests: Declaration of Competing Interest None declared., (Copyright © 2023 The Authors.

The SPROUT (Survey on reproduction in RheUmaTology) study explored current practice in women of childbearing age with systemic autoimmune rheumatic diseases, investigating the counselling on contraception, the prescription of low dose acetylsalicylic acid (LDASA) to pregnant patients and the management of disease activity in the post-partum period. The SPROUT questionnaire was designed ad hoc and promoted in the three months before the "11 th International Conference on Reproduction, Pregnancy and Rheumatic Disease". Between June and August 2021, 121 physicians responded to the survey. Even though 66.8% of the participants declared themselves to be confident in counselling surrounding birth control, only 62.8% of physicians always discuss contraception and family planning with women of childbearing age. Approximately 20% of respondents do not prescribe LDASA to pregnant women with rheumatic diseases, and wide heterogeneity exists in the dose and timing of LDASA prescription. Most respondents (43.8%) restart treatment with biological agents soon after delivery to prevent disease flares, opting for a drug compatible with breastfeeding while 41.3% of physicians continue biologics throughout pregnancy and post-partum. The SPROUT study highlighted the necessity to further foster physicians' education and identified the management of disease activity after delivery as a matter for discussion between all the clinicians involved in the care of pregnant women with rheumatic conditions., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest., (Copyright © 2023.

Autoimmune rheumatic diseases (ARD) can affect women and men during fertile age, therefore reproductive health is a priority issue in rheumatology. Many topics need to be considered during preconception counselling: fertility, the impact of disease-related factors on pregnancy outcomes, the influence of pregnancy on disease activity, the compatibility of medications with pregnancy and breastfeeding. Risk stratification and individualized treatment approach elaborated by a multidisciplinary team minimize the risk of adverse pregnancy outcomes (APO). Research has been focused on identifying biomarkers that can be predictive of APO. Specifically, preeclampsia and hypertensive disorders of pregnancy tend to develop more frequently in women with ARD. Placental insufficiency can lead to intrauterine growth restriction and small-for-gestational age newborns. Such APO have been shown to be associated with maternal disease activity in different ARD. Therefore, a key message to be addressed to the woman wishing for a pregnancy and to her family is that treatment with compatible drugs is the best way to ensure maternal and fetal wellbeing. An increasing number of medications have entered the management of ARD, but data about their use in pregnancy and lactation are scarce. More information is needed for most biologic drugs and their biosimilars, and for the so-called small molecules, while there is sufficient evidence to recommend the use of TNF inhibitors if needed for keeping maternal disease under control. Other issues related to the reproductive journey have emerged as "unmet needs", such as sexual dysfunction, contraception, medically assisted reproduction techniques, long-term outcome of children, and they will be addressed in this review paper. Collaborative research has been instrumental to reach current knowledge and the future will bring novel insights thanks to pregnancy registries and prospective studies that have been established in several Countries and to their joint efforts in merging data., Competing Interests: Declaration of Competing Interest None declared., (Copyright © 2022 Elsevier B.V.

COVID-19 is a new pandemic, caused by Severe Acute Respiratory Syndrome-CoronaVirus-2 (SARS-Cov2) infection and characterized by a broad spectrum of clinical manifestations. Inflammation and the innate immune system have been recently recognized as pivotal players in the most severe forms, characterized by significantly elevated levels of pro-inflammatory cytokines. In this setting, several studies have also reported the presence of abnormalities in coagulation parameters and platelets count, possibly identifying a subgroup of patients with poor prognosis. Some reports of full-blown thromboembolic events are emerging. Among the possible mechanisms underlying coagulation dysfunction, the so-called "cytokine storm" seems to play a pivotal role. Other candidate factors include virus-specific mechanisms, related to the virus interaction with renin angiotensin system (RAS) and the fibrinolytic pathway, but also comorbidities affecting these patients. Coagulation dysfunction is therefore a candidate risk factor for adverse outcomes in COVID-19 and should be carefully addressed in clinical practice., (Copyright © 2020 Elsevier Ltd.

Background: Trial of Rivaroxaban in AntiPhospholipid Syndrome was a prospective randomized, open-label, noninferiority study conducted in 14 centers in Italy. Rivaroxaban was compared with warfarin for the prevention of thromboembolic events, major bleeding, and vascular death in high-risk, triple-positive patients with antiphospholipid syndrome., Objective: The aim of this paper is to report the events during the 2-year follow-up after the study closure., Methods: On January 28, 2018, the trial was prematurely stopped by adjudication and safety committee for an excess of events in the rivaroxaban group. Randomized patients were advised on trial results and those randomized to rivaroxaban were solicited to switch to warfarin. All 14 participating centers were asked and accepted to follow their patients for clinical events. This report describes the rate of events that occurred between January 28, 2018, and January 28, 2020., Results: Of 120 randomized patients, 115 were available for follow-up. Outcome events were two in six (33.3%) patients who remained on direct oral anticoagulants (DOACs) and six in 109 (5.7%) patients on warfarin (hazard ratio [HR] 6.9; 95% confidence interval [CI] 1.4-34.5, P = .018). The two patients on DOACs (one taking dabigatran and one taking rivaroxaban) suffered from thromboembolic events, whereas of the six patients with composite outcomes on warfarin, three had thromboembolic events (HR for thrombosis 13.3; 95% CI 2.2-79.9, P = .005)., Conclusion: These data further support the use of warfarin in high-risk patients with antiphospholipid syndrome., (© 2020 International Society on Thrombosis and Haemostasis.)

Autoimmune rheumatic diseases (ARDs) are chronic conditions with a striking female predominance, frequently affecting women of childbearing age. Sex hormones and gender dimorphism of immune response are major determinants in the multifactorial pathogenesis of ARDs, with significant implications throughout reproductive life. Particularly, pregnancy represents a challenging condition in the context of autoimmunity, baring profound hormonal and immunologic changes, which are responsible for the bi-directional interaction between ARDs outcome and pregnancy course. In the latest years epigenetics has proven to be an important player in ARDs pathogenesis, finely modulating major immune functions and variably tuning the significant gender effects in autoimmunity. Additionally, epigenetics is a recognised influencer of the physiological dynamic modifications occurring during pregnancy. Still, there is currently little evidence on the pregnancy-related epigenetic modulation of immune response in ARDs patients. This review aims to overview the current knowledge of the role of epigenetics in the context of autoimmunity, as well as during physiologic and pathologic pregnancy, discussing under-regarded aspects in the interplay between ARDs and pregnancy pathology. The outline of a new ongoing European project will be presented., (Copyright © 2020. Published by Elsevier B.V.)

Azathioprine (AZA), an oral immunosuppressant, is safe during pregnancy. Some reports suggested different impairments in the offspring of mothers with autoimmune diseases (AI) exposed in utero to AZA. These observations are available from retrospective studies or case reports. However, data with respect to the long-term safety in the antenatally exposed child are still lacking. The aim of this study is to summarize the current knowledge in this field and to focus on the need for a prospective study on this population. We performed a PubMed search using several search terms. The actual data show that although the risk of congenital anomalies in offspring, as well as the infertility risk, are similar to those found in general population, there is a higher incidence of prematurity, of lower weight at birth and an intra-uterine delay of development. There is also an increased risk of materno- fetal infections, especially cytomegalovirus infection. Some authors raise the interrogations about neurocognitive impairment. Even though the adverse outcomes might well be a consequence of maternal illness and disease activity, interest has been raised about a contribution of this drug. However, the interferences between the external agent (in utero exposure to AZA), with the host (child genetic susceptibility, immune system anomalies, emotional status), environment (public health, social context, availability of health care), economic, social, and behavioral conditions, cultural patterns, are complex and represent confounding factors. In conclusion, it is necessary to perform studies on the medium and long-term outcome of children born by mothers with autoimmune diseases, treated with AZA, in order to show the safety of AZA exposure. Only large-scale population studies with long-term follow-up will allow to formally conclude in this field.

Introduction: The aim of this narrative review is to provide an overview of the literature on the possible immunologic pathophysiology of psychiatric manifestations of neuropsychiatric systemic lupus erythematosus (NPSLE)., Methods: A systematic search on PubMed was conducted. English studies with full text availability that investigated the correlation between blood-brain barrier (BBB) dysfunction, intrathecal synthesis of antibodies, antibodies, cytokines, chemokines, metalloproteinases, complement and psychiatric NPSLE manifestations in adults were included., Results: Both transient BBB-dysfunction with consequent access of antibodies to the cerebrospinal fluid (CSF) and intrathecal synthesis of antibodies could occur in psychiatric NPSLE. Anti-phospholipid antibodies, anti-NMDA antibodies and anti-ribosomal protein p antibodies seem to mediate concentration dependent neuronal dysfunction. Interferon-α may induce microglial engulfment of neurons, direct neuronal damage and production of cytokines and chemokines in psychiatric NPSLE. Several cytokines, chemokines and matrix metalloproteinase-9 may contribute to the pathophysiology of psychiatric NPSLE by attracting and activating Th1-cells and B-cells., Discussion: This potential pathophysiology may help understand NPSLE and may have implications for the diagnostic management and therapy of psychiatric NPSLE. However, the presented pathophysiological model is based on correlations between potential immunologic etiologies and psychiatric NPSLE that remain questionable. More research on this topic is necessary to further elucidate the pathophysiology of NPSLE., Competing Interests: Declaration of Competing Interest No conflicts of interest were stated. This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors., (Copyright © 2020 The Author(s). Published by Elsevier B.V.

A hyperinflammatory syndrome (HIS) may cause a life-threatening acute respiratory distress syndrome (ARDS) in patients with COVID-19 pneumonia. A prospective series of 100 consecutive patients admitted to the Spedali Civili University Hospital in Brescia (Italy) between March 9th and March 20th with confirmed COVID-19 pneumonia and ARDS requiring ventilatory support was analyzed to determine whether intravenous administration of tocilizumab (TCZ), a monoclonal antibody that targets the interleukin 6 (IL-6) receptor, was associated with improved outcome. Tocilizumab was administered at a dosage of 8 mg/kg by two consecutive intravenous infusions 12 h apart. A third infusion was optional based on clinical response. The outcome measure was an improvement in acute respiratory failure assessed by means of the Brescia COVID Respiratory Severity Score (BCRSS 0 to 8, with higher scores indicating higher severity) at 24-72 h and 10 days after tocilizumab administration. Out of 100 treated patients (88 M, 12 F; median age: 62 years), 43 received TCZ in the intensive care unit (ICU), while 57 in the general ward as no ICU beds were available. Of these 57 patients, 37 (65%) improved and suspended noninvasive ventilation (NIV) (median BCRSS: 1 [IQR 0-2]), 7 (12%) patients remained stable in NIV, and 13 (23%) patients worsened (10 died, 3 were admitted to ICU). Of the 43 patients treated in the ICU, 32 (74%) improved (17 of them were taken off the ventilator and were discharged to the ward), 1 (2%) remained stable (BCRSS: 5) and 10 (24%) died (all of them had BCRSS≥7 before TCZ). Overall at 10 days, the respiratory condition was improved or stabilized in 77 (77%) patients, of whom 61 showed a significant clearing of diffuse bilateral opacities on chest x-ray and 15 were discharged from the hospital. Respiratory condition worsened in 23 (23%) patients, of whom 20 (20%) died. All the patients presented with lymphopenia and high levels of C-reactive protein (CRP), fibrinogen, ferritin and IL-6 indicating a HIS. During the 10-day follow-up, three cases of severe adverse events were recorded: two patients developed septic shock and died, one had gastrointestinal perforation requiring urgent surgery and was alive at day 10. In conclusion, our series showed that COVID-19 pneumonia with ARDS was characterized by HIS. The response to TCZ was rapid, sustained, and associated with significant clinical improvement., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Autoimmune diseases often affect young women and this may represent a problem in family planning. Pregnancies in these patients may carry several complications but nowadays the continued amelioration in treatment and management has greatly improved the pregnancy outcome. The main concern of these women obviously is the short- and long-term outcome of their children. A child born from a woman with autoimmune disease is potentially exposed in utero to maternal autoantibodies, cytokines, and drugs, and each item could impair his or her development. In addition, the maternal genetic heritage can favor autoimmunity. All these items could have a role, for example, in the development of autoimmune diseases (the same as the mother or different ones) or neurological disorders. Data in literature are controversial. This review will gather the available data possibly providing a useful tool for counseling future mothers., Competing Interests: Declaration of Competing Interest The authors have no conflicts of interest., (Copyright © 2019.

Introduction: The effectiveness of CD20 targeting in connective tissue diseases (CTD) with lung involvement is controversial. This paper aims to review the current evidence about rituximab (RTX) use in CTD-related interstitial lung disease (ILD)., Methods: We performed a systematic review of papers published between January 2009 and May 2019. We included clinical trials, case/control studies and cohort studies. We excluded letters, case reports, case series, reviews, and full articles when not in English. The selected studies listed as primary or secondary outcome a variation in pulmonary function tests or in the scores used to radiologically stage lung involvement, in CTD-related ILD patients after RTX., Results: Out of 1206 potentially eligible articles, 24 papers were selected: 3 retrospectively described cohorts of patients with different CTD, 14 dealt with systemic sclerosis (SSc)-related ILD, 5 with idiopathic inflammatory myopathies (IIMs)-related ILD, and 2 with Sjögren's Syndrome-related ILD. A direct comparison of the selected studies was hampered by their heterogeneity for outcomes, follow-up duration, the severity of lung involvement, and clinical features of study populations. However, an overall agreement existed concerning the effectiveness of RTX in the stabilization of lung disease, with some studies reporting an improvement of functional parameters from baseline. IIM-related ILD appeared more responsive than other CTD-related ILD to CD20 targeting., Conclusion: RTX is a promising therapeutic tool in CTD-related ILD. This systematic review remarks the unmet need of multicenter prospective studies aiming to evaluate the effectiveness of RTX with adequate sample size and study design., (Copyright © 2019 Elsevier B.V.

Background: Variability remains a challenge in lupus anticoagulant (LA) testing., Objective: To validate LA test performance between Antiphospholipid Syndrome Alliance for Clinical Trials and International Networking (APS ACTION) Core laboratories and examine agreement in LA status between Core and local/hospital laboratories contributing patients to this prospective registry., Methods: Five Core laboratories used the same reagents, analyzer type, protocols, and characterized samples for LA validation. Non-anticoagulated registry samples were retested at the corresponding regional Core laboratories and anticoagulated samples at a single Core laboratory. Categorical agreement and discrepancies in LA status between Core and local/hospital laboratories were analyzed., Results: Clotting times for the reference/characterized plasmas used for normalized ratios were similar between Core laboratories (CV <4%); precision and agreement for LA positive/negative plasma were similar (all CV ≤5%) in the four laboratories that completed both parts of the validation exercise; 418 registry samples underwent LA testing. Agreement for LA positive/negative status between Core and local/hospital laboratories was observed in 87% (115/132) non-anticoagulated and 77% (183/237) anticoagulated samples. However, 28.7% (120/418) of samples showed discordance between the Core and local/hospital laboratories or equivocal LA results. Some of the results of the local/hospital laboratories might have been unreliable in 24.7% (41/166) and 23% (58/252) of the total non-anticoagulated and anticoagulated samples, respectively. Equivocal results by the Core laboratory might have also contributed to discordance., Conclusions: Laboratories can achieve good agreement in LA performance by use of the same reagents, analyzer type, and protocols. The standardized Core laboratory results underpin accurate interpretation of APS ACTION clinical data., (© 2019 International Society on Thrombosis and Haemostasis.)

Antiphospholipid Syndrome (APS) is the commonest treatable cause of recurrent miscarriage and pharmacological treatment of pregnant patients with antiphospholipid antibodies (aPL) should aim at preventing obstetric complications and maternal thrombotic events. Conventional treatment for patients with an established diagnosis of obstetric APS (OAPS), generally resulting in over 70-80% successful pregnancies. Since seropositive (SP)-APS and seronegative (SN)-APS patients had shown similar clinical profiles, patients with SN- OAPS, as well as SP-OAPS, should receive combined treatment in order to improve the pregnancy prognosis; indeed, current standard of care increased good pregnancy outcome in SN-APS, with similar effect to confirmed APS. The above data suggest that there are patients with the clinical manifestations of OAPS but persistently negative to conventional aPL that need to be identified to ensure adequate therapy and therefore a better prognosis. The clinical utility of non-criteria aPL in the diagnosis of SN-APS is still a matter of debate. In the last decade more and more studies have reported the presence of patients suffering from SN-APS in which non-conventional ("non-criteria") aPL might be present or antibodies may be detected using methodological approaches different from the traditional assays. To improve test standardization large prospective, multicenter, and multinational studies are needed. Therefore, when assessing a patient with clinical manifestations consistent with OAPS but aPL negative using the conventional available assays, the clinician should consider the possibility that the patient is affected with SN-APS., (Copyright © 2019 Elsevier B.V.

Pregnancy in autoimmune diseases remains an argument of debate. In last years great improvements were done and with the correct medical support women with disease such as Systemic Lupus Erythematosus or Antiphospholipid Syndrome can afford a pregnancy and have healthy babies. The starting point is a good counselling. Women should be informed about risks that can occur taking some medications while pregnant and, on the other hand, that there are medications that can be safety assumed during pregnancy. Furthermore, there are known maternal risks factor such as the presence of antiphospholipid antibodies or anti-Ro/SSA antibodies that must be carefully manage by both rheumatologists and obstetrics. In addition, also disease activity during pregnancy can represent an issue. For all these reason, a multidisciplinary approach is mandatory in order to give our patients an optimal medical support, before, during and after pregnancy., (Copyright © 2019.

Infertility consists by definition in" failure to achieve a clinical pregnancy after 12 months or more of regular unprotected intercourse" while the term subfertility means a delay to achieve pregnancy. Several factors can contribute to infertility or subfertility in patients with systemic autoimmune diseases. The association of systemic autoimmune conditions with endometriosis, celiac disease and thyroid autoimmunity that are well known causes of infertility and/or subfertility need to be taken in consideration when difficulties in the onset of pregnancy is reported. The majority of the used antirheumatic drugs do not interfere with fertility. However, the use of cyclophosphamide, limited to severe disease, can provoke premature ovarian failure; to preserve fertility a preventive treatment is available. Nonsteroidal anti-inflammatory drugs can cause temporary infertility and corticosteroids are associated to a prolonged time to pregnancy in some rheumatic diseases. Data on the association of antiphospholipid antibodies (aPL) with infertility are still debated but in general an increased rate of aPL is described patients undergoing medically assisted reproductive techniques. In systemic lupus erythematosus aPL and other autoantibodies (i.e. anti-oocytes) can contribute to the infertility of some patients. Subfertility, rather than infertility, is observed in patients with rheumatoid arthritis; the particular physical conditions of these women can also account for this. Physicians should not forget the patients' age, that is mandatory in order to preserve their chance to have children., (Copyright © 2019. Published by Elsevier Ltd.)

Pregnancy requires a special management in women with inflammatory rheumatic diseases (RDs), with the aim of controlling maternal disease activity and avoiding fetal complications. Despite the heterogeneous course of RDs during pregnancy, their impact on pregnancy largely relates to the extent of active inflammation at the time of conception. Therefore, accurate evaluation of disease activity is crucial for the best management of pregnant patients. Nevertheless, there are limitations in using conventional measures of disease activity in pregnancy, as some items included in these instruments can be biased by symptoms or by physiological changes related to pregnancy and the pregnancy itself may influence laboratory parameters used to assess disease activity. This article aims to summarize the current literature about the available instruments to measure disease activity during pregnancy in RDs. Systemic lupus erythematosus is the only disease with instruments that have been modified to account for several adaptations which might interfere with the attribution of signs or symptoms to disease activity during pregnancy. No modified-pregnancy indices exist for women affected by other RDs, but standard indices have been applied to pregnant patients. The current body of knowledge shows that the physiologic changes that occur during pregnancy need to be either adapted from existing instruments or developed to improve the management of pregnant women with RDs. Standardized instruments to assess disease activity during pregnancy would be helpful not only for clinical practice but also for research purposes., (Copyright © 2018 Elsevier B.V.

The relapse rate in antiphospholipid syndrome (APS) remains high, i.e. around 20%-21% at 5 years in thrombotic APS and 20-28% in obstetrical APS [2, 3]. Hydroxychloroquine (HCQ) appears as an additional therapy, as it possesses immunomodulatory and anti-thrombotic various effects [4-16]. Our group recently obtained the orphan designation of HCQ in antiphospholipid syndrome by the European Medicine Agency. Furthermore, the leaders of the project made the proposal of an international project, HIBISCUS, about the use of Hydroxychloroquine in secondary prevention of obstetrical and thrombotic events in primary APS. This study has been launched in several countries and at now, 53 centers from 16 countries participate to this international trial. This trial consists in two parts: a retrospective and a prospective study. The French part of the trial in thrombosis has been granted by the French Minister of Health in December 2015 (the academic trial independent of the pharmaceutical industry PHRC N PAPIRUS) and is coordinated by one of the members of the leading consortium of HIBISCUS., (Copyright © 2018.

Rivaroxaban is an effective and safe alternative to warfarin in patients with atrial fibrillation and venous thromboembolism. We tested the efficacy and safety of rivaroxaban compared with warfarin in high-risk patients with thrombotic antiphospholipid syndrome. This is a randomized open-label multicenter noninferiority study with blinded end point adjudication. Rivaroxaban, 20 mg once daily (15 mg once daily based on kidney function) was compared with warfarin (international normalized ratio target 2.5) for the prevention of thromboembolic events, major bleeding, and vascular death in patients with antiphospholipid syndrome. Only high-risk patients triple positive for lupus anticoagulant, anti-cardiolipin, and anti-β2-glycoprotein I antibodies of the same isotype (triple positivity) were included in the study. The trial was terminated prematurely after the enrollment of 120 patients (59 randomized to rivaroxaban and 61 to warfarin) because of an excess of events among patients in the rivaroxaban arm. Mean follow-up was 569 days. There were 11 (19%) events in the rivaroxaban group, and 2 (3%) events in the warfarin group. Thromboembolic events occurred in 7 (12%) patients randomized to rivaroxaban (4 ischemic stroke and 3 myocardial infarction), whereas no event was recorded in those randomized to warfarin. Major bleeding occurred in 6 patients: 4 (7%) in the rivaroxaban group and 2 (3%) in the warfarin group. No death was reported. The use of rivaroxaban in high-risk patients with antiphospholipid syndrome was associated with an increased rate of events compared with warfarin, thus showing no benefit and excess risk. This trial was registered at www.clinicaltrials.gov as #NCT02157272., (© 2018 by The American Society of Hematology.)

Aim: To describe the consecutive pregnancy outcome and treatment in refractory obstetrical antiphospholipid syndrome (APS)., Methods: Retrospective multicenter open-labelled study from December 2015 to June 2016. We analyzed the outcome of pregnancies in patients with obstetrical APS (Sydney criteria) and previous adverse obstetrical event despite low-dose aspirin and low-molecular weight heparin LMWH (LMWH) conventional treatment who experienced at least one subsequent pregnancy., Results: Forty nine patients with median age 27years (23-32) were included from 8 European centers. Obstetrical APS was present in 71%, while 26% had obstetrical and thrombotic APS. Lupus anticoagulant was present in 76% and triple antiphospholipid antibody (APL) positivity in 45% of patients. Pregnancy loss was noted in 71% with a median age of gestation of 11 (8-21) weeks. The presence of APS non-criteria features (35% vs 17% in pregnancies without adverse obstetrical event; p=0.09), previous intrauterine death (65% vs 38%; p=0.06), of LA (90% vs 65%; p=0.05) were more frequent in pregnancies with adverse pregnancy outcome, whereas isolated recurrent miscarriage profile was more frequent in pregnancies without any adverse pregnancy outcome (15% vs 41%; p=0.04). In univariate analysis considering all pregnancies (index and subsequent ones), an history of previous intrauterine death was associated with pregnancy loss (odds-ratio 2.51 (95% CI 1.274.96); p=0.008), whereas previous history of prematurity related to APS (odds-ratio 0.13 95%CI 0.04 0.41, P=0.006), steroids use during the pregnancy (odds-ratio 0.30 95% CI 0.11-0.82, p=0.019) and anticardiolipids isolated profile (odds-ratio 0.51 95% CI 0.26-1.03, p=0.0588) were associated with favorable outcome. In multivariate analysis, only previous history of prematurity, steroids use and anticardiolipids isolated profiles were associated with live-birth pregnancy., Conclusion: The main features of refractory obstetrical APS were the high rates of LA and triple APL positivity. Steroids could be effective in this APS profile, but prospective studies are necessary., (Copyright © 2017 Elsevier B.V. All rights reserved.)

Objective: To collect data on vitamin D (25(OH)D) serum levels in a large number of rheumatoid arthritis (RA) patients from different European countries, to investigate their relation with disease activity, disability, quality of life, and possibly to construct a new Patient Reported Outcome (PRO) questionnaire in order to self-estimate if they are at risk for vitamin D insufficiency/deficiency-related clinical implications (D-PRO)., Methods: This was a European League Against Rheumatism (EULAR) supported cross-sectional study (project No CLI064) which involved 625 RA patients (mean age 55±11years, mean disease duration 11±9years), 276 age and sex matched healthy subjects, and rheumatologists working in academic institutions or hospital centres, as well as PARE organizations (patient representatives) from 13 European countries. Serum samples for 25(OH)D level measurement were collected during winter time and analyzed in a central laboratory using chemiluminescence immunoassay (DiaSorin). Patient past medical history was recorded. RA patients were provided with three questionnaires: the Rheumatoid Arthritis Impact Diseases score (RAID), the Health Assessment Questionnaire (HAQ), and the new D-PRO questionnaire at the time of 25(OH)D serum sampling. D-PRO questionnaire consisted of three domains, Symptom Risk Score (SRS), Habitus Risk Score (HRS) and Global Risk Score (SRS+HRS=GRS), constructed with items possibly related to vitamin D deficiency. D-PRO was correlated with both clinical and PRO scores. DAS28-CRP was also evaluated. Statistical analysis was performed by non parametric tests., Results: Mean serum concentration of 25(OH)D in RA patients (17.62±9.76ng/ml) was found significantly lower if compared to the levels obtained in matched controls (18.95±9.45ng/ml) (p=0.01), with statistically significant differences among several European countries. Negative correlations were found between 25(OH)D serum levels and DAS28-CRP (p<0.001), RAID (p=0.05) and HAQ (p=0.04) scores in the RA patients group. Negative correlations were also found in the cohort of enrolled RA patients between 25(OH)D serum concentrations and SRS (p=0.04), HRS (p=0.02) and GRS (p=0.02) domains of the D-PRO questionnaire., Conclusions: This first multicentre European survey add new evidences that vitamin D insufficiency/deficiency is frequent in RA patients with statistically significant differences among several countries. Vitamin D serum concentrations seem to correlate negatively and significantly with the D-PRO Global Risk Score, clinimetric indexes for quality of life, disease activity and disability in present cohort of RA European patients., (Copyright © 2017 Elsevier B.V.

Objective: Systemic vasculitis (SV) are uncommon diseases that rarely affect women during their reproductive age; little data, mainly retrospective, is available on this topic. The aim of our study was to evaluate maternal/neonatal outcome and disease course before, during and after pregnancy., Methods: Sixty-five pregnancies in 50 women with SV were followed by a multispecialistic team in 8 institutions between 1995 and 2014. Clinical data on pregnancy, 1year before and 1year after delivery was retrospectively collected. The rate of pregnancy complications was compared to that of a General Obstetric Population (GOP) of 3939 women., Results: In 2 patients the diagnosis of SV was done during pregnancy; 59 out of the remaining 63 started when maternal disease was quiescent. We recorded 56 deliveries with 59 live births, 8 miscarriages and 1 fetal death. In SV, preterm, particularly early preterm (<34weeks) deliveries and cesarean sections appeared significantly more frequent than in GOP (11.3% vs 5.0%, p=0.049 and 48.2% vs 31.0%, p=0.009). Vasculitis-related complications occurred in 23 pregnancies (35.4%), with 5 severe events (7.7%) including 3 cases of transient ischemic attack (TIA). Data about the post-partum period were available for 56 pregnancies: 12 flares (21.4%) occurred, with 1 severe event (1.8%)., Conclusion: SV patients can have successful pregnancies (especially during a disease remission phase) despite an increased rate of preterm delivery. Severe flares were limited, but the occurrence of 3 TIA suggests that particular attention should be given to possible thrombotic complications in SV patients during pregnancy and puerperium., (Copyright © 2015 Elsevier B.V.

In European multicenter study, we aimed to describe the real-life hydroxychloroquine use in APS patients during pregnancy and determine its benefit in refractory obstetrical APS. We analyzed the outcome of pregnancies treated by hydroxychloroquine in patients with APS or asymptomatic antiphospholipid (aPL) antibodies carriers. Thirty patients with APS with 35 pregnancies treated by hydroxychloroquine were analyzed. Comparing the outcome of pregnancies treated by the addition of hydroxychloroquine to previous pregnancies under the conventional treatment, pregnancy losses decreased from 81% to 19% (p<0.05), without differences in the associated treatments. The univariate analysis showed that the previous intrauterine deaths and higher hydroxychloroquine amount (400mg per day) were the factors associated with pregnancy outcome. Considering 14 patients with previous refractory obstetrical APS (n=5 with obstetrical and thrombotic primary APS and n=9 with purely obstetrical APS), all with previous pregnancy losses under treatment (aspirin with LMWH in 11 cases and LMWH in 3 cases), the addition of hydroxychloroquine resulted in live born babies in 11/14 (78%) cases (p<0.05). Our study shows the benefit of hydroxychloroquine addition in patients with refractory obstetrical APS and raises the need of prospective studies to confirm our preliminary study., (Copyright © 2015 Elsevier B.V.

Throughout the last decade, increasing awareness has been raised on issues related to reproduction in rheumatic diseases including basic research to clarify the important role of estrogens in the etiology and pathophysiology of immune/inflammatory diseases. Sub- or infertility is a heterogeneous condition that can be related to immunological mechanisms, to pregnancy loss, to disease burden, to therapy, and to choices in regard to family size. Progress in reproductive medicine has made it possible for more patients with rheumatic disease to have children. Active disease in women with rheumatoid arthritis (RA) affects their children's birth weight and may have long-term effects on their future health status. Pregnancy complications as preeclampsia and intrauterine growth restriction are still increased in patients with systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS), however, biomarkers can monitor adverse events, and several new therapies may improve outcomes. Pregnancies in women with APS remain a challenge, and better therapies for the obstetric APS are needed. New prospective studies indicate improved outcomes for pregnancies in women with rare diseases like systemic sclerosis and vasculitis. TNF inhibitors hold promise for maintaining remission in rheumatological patients and may be continued at least in the first half of pregnancy. Pre-conceptional counseling and interdisciplinary management of pregnancies are essential for ensuring optimal pregnancy outcomes., (Copyright © 2014 Elsevier B.V. All rights reserved.)

Current classification criteria for definite Antiphospholipid Syndrome (APS) require the use of three laboratory assays to detect antiphospholipid antibodies (aCL, anti-β2GPI and LA) in the presence of at least one of the two major clinical manifestations (i.e. thrombosis or pregnancy morbidity) of the syndrome. However, several other autoantibodies shown to be directed to other proteins or their complex with phospholipids have been proposed to be relevant to APS but their clinical utility and their diagnostic value remains elusive. This report summarizes the findings, conclusions and recommendations of the "APS Task Force 3-Laboratory Diagnostics and Trends" meeting that took place during the 14th International Congress on Antiphospholipid Antibodies (APLA 2013, September 18-21, Rio de Janeiro, RJ, Brazil)., (Copyright © 2014 Elsevier B.V.

Pregnancy morbidity is one of the clinical manifestations used for classification criteria of antiphospholipid syndrome (APS). During the 14th International Congress on Antiphospholipid Antibodies (aPL), a Task Force with internationally-known experts was created to carry out a critical appraisal of the literature available regarding the association of aPL with obstetric manifestations present in actual classification criteria (recurrent early miscarriage, fetal death, preeclampsia and placental insufficiency) and the quality of the evidence that treatment(s) provide benefit in terms of avoiding recurrent adverse obstetric outcomes. The association of infertility with aPL and the effectiveness of the treatment of patients with infertility and positive aPL was also investigated. This report presents current knowledge and limitations of published studies regarding pregnancy morbidity, infertility and aPL, identifying areas that need better investigative efforts and proposing how critical flaws could be avoided in future studies, as suggested by participants of the Task Force. Except for fetal death, there are limitations in the quality of the data supporting the association of aPL with obstetric complications included in the current APS classification criteria. Recommended treatments for all pregnancy morbidity associated to APS also lack well-designed studies to confirm its efficacy. APL does not seem to be associated with infertility and treatment does not improve the outcomes in infertile patients with aPL. In another section of the Task Force, Dr. Jane Salmon reviewed complement-mediated inflammation in reproductive failure in APS, considering new therapeutic targets to obstetric APS (Ob APS)., (Copyright © 2014 Elsevier B.V.

The use of high intensity anticoagulation in the prevention of recurrence of arterial thrombosis related to the Antiphospholipid Syndrome (APS) is still controversial. This paper reports a debate that took place at the CORA meeting (Controversies in Rheumatology and Autoimmunity), held in Florence in March 2011. Major points of discussion were: 1) the paucity of prospective randomized clinical trials; retrospective studies were the main source supporting the use of high intensity anticoagulation; 2) heterogeneity in antiphospholipid antibodies (aPL) definition, due to the lack of standardization of aPL assays and to the failure to distinguish patients with a high risk profile ("triple positive") from those a low risk profile; 3) bleeding is a major concern about high intensity anticoagulation; however, studies are not concordant in reporting an increased risk compared to the standard regimen; 4) practical issues consist of difficulties in keeping a stable PT-INR over 3 and the possibility for interference by aPL on the thromboplastins used for PT-INR measurement. In conclusion, there is currently a lack of consensus on the use of high intensity anticoagulation for the secondary prophylaxis of arterial thrombosis. However, such a treatment may be particularly recommended in those APS patients who have a high risk aPL profile and other concomitant cardiovascular risk factors, provided that the potential benefit outweighs the risk of bleeding., (Copyright © 2011 Elsevier B.V.

Antiphospholipid syndrome is an auto-immune disorder characterised by recurrent thrombosis, pregnancy losses and the presence of antiphospholipid antibodies. Although it was initially considered an auto-immune coagulopathy, it is now clear that it is a complex and systemic disease. A large number of manifestations in different organs and tissues (cardiac, pulmonary, neurological, renal, cutaneous, haematologic, gastrointestinal, ocular, skeletal and endocrinologic) have been described in these patients. A small group of patients can have a microvascular involvement, which is the most common pathological finding in patients affected by the catastrophic variant of the syndrome. A strong relationship exists between the antiphospholipid syndrome and systemic lupus erythematosus, as demonstrated by common clinical, serological and genetic features and by the few but possible cases evolving from the first disease into the second one over years. Finally, the systemic nature of the antiphospholipid syndrome and the understanding of the mechanisms of antiphospholipid-mediated damage suggest a role of immunomodulation beyond anticoagulation in the therapeutic approach to the disease., (© 2012 Elsevier Ltd.

Rheumatic diseases can affect women during their childbearing age. Therefore, physicians should introduce a discussion with the patients about pregnancy and its problems. Lupus pregnancies can be successful, even in patients with renal disease, when planned in remission state; the use of low dose aspirin was shown to be an independent predictor of good outcome, so it can be suggested as a preventive measure. Pregnancies in women with Antiphospholipid Syndrome can fail even if properly treated, especially when associated with a systemic autoimmune disease, a history of both thrombosis and pregnancy morbidity, and a triple positivity of antiphospholipid antibody assays. Women with systemic sclerosis have generally a good obstetric outcome, except for an increase rate of preterm deliveries. Severe disease complications were sometimes reported, but their relationship with gestation is not clear yet. Although data on human pregnancy are still preliminary, anti-TNF agents are classified as non teratogens in contrast to methotrexate and leflunomide. So women affected by aggressive chronic arthritis may be treated with anti-TNF in the pre-conceptional period, discontinuing the drug as soon as pregnancy starts. In order to increase maternal compliance and cope with difficult cases, a multidisciplinary team (rheumatologists/internists, obstetricians and neonatologists) should take care of patients during pregnancy., (Copyright © 2010 Elsevier B.V.

Plasmacytoid dendritic cells (PDC) represent the main type I interferon (IFN-I) producing cells. Emerging evidence supports a role for IFN-I in autoimmune diseases. Given the central role of PDC in the pathogenesis of systemic lupus erythematosus (SLE), we investigated the effect of Trichostatin A (TSA), a prototypic histone deacetylase inhibitor, on PDC activation. TSA inhibited the production of IFN-I, TRAIL and of the pro-inflammatory cytokines TNFalpha and IL-6 by CpG-activated PDC. These effects were associated with the inhibition of IFN Regulatory Factor (IRF)-7 nuclear translocation. Furthermore, TSA was also effective in inhibiting the production of IFNalpha by PDC cultured in vitro in the presence of serum obtained from SLE patients. This study describes a new level of regulation of immune responses by histone deacetylase inhibitors and defines the molecular basis for new strategies to be exploited in the treatment of autoimmune diseases., (Copyright 2010 Elsevier GmbH.
