Anti-SSA/Ro positivity and congenital heart block: obstetric and foetal outcome in a cohort of anti-SSA/Ro positive pregnant patients with and without autoimmune diseases.

OBJECTIVES: Neonatal lupus (NL) is an acquired disease caused by the transplacental passage of anti-SSA/Ro antibodies. The rate of congenital heart block (CHB), its most serious manifestation, ranges from 1 to 5%. The aim of this study was to retrospectively assess the prevalence of CHB in anti-SSA/Ro positive pregnant women with or without systemic autoimmune diseases from 2010 to 2020. METHODS: Patients underwent monthly visit and a shared follow-up programme of weekly (16th-24th week) foetal heart rate assessment by obstetric ultrasound. RESULTS: 322 pregnancies in 258 anti-SSA/Ro patients were included; 314 were followed from the beginning of pregnancy because of the known presence of anti-SSA/Ro autoantibodies and 1 case of CHB occurred in an anti-SSA/Ro+ asymptomatic subject (0.3%). In the same period, 8 additional patients were referred to our clinics after in utero CHB diagnosis and subsequent discovery of anti-SSA/Ro without a disease diagnosis. Globally, 9 cases of congenital CHB (2.8%) occurred: 7 complete, 1 II-III degree and 1 rst degree CHB. Anti-SSB/La positivity was associated with a higher risk of CHB (7.8% vs. 1.2%; p=0.0071). No differences in maternal or foetal outcomes were found in comparison with a large cohort of unselected pregnancies except for caesarian section. Hydroxychloroquine (HCQ) was used in 58.3% pregnancies, with a different prevalence according with maternal diagnosis. CONCLUSIONS: Our data suggest that anti-SSA/Ro positive patents with a de ned systemic autoimmune disease undergoing a strict follow-up since positive pregnancy test display a low risk of pregnancy complications, including but not limited to NL.

Findings from a multicentre, observational study on reproductive outcomes in women with unexplained recurrent pregnancy loss: the OTTILIA registry.

STUDY QUESTION: What evaluation and care is offered to women after unexplained recurrent pregnancy loss (RPL) or intra-uterine foetal death (IUFD) and what are the reproductive outcomes? SUMMARY ANSWER: Women are assessed for thrombophilia and often treated with low-molecular weight heparin (LMWH) and/or low-dose aspirin (ASA). WHAT IS KNOWN ALREADY: Randomized controlled trials (RCTs) on possible efficacy of heparins and/or aspirin have been inconclusive due to limited power to detect a difference and patient heterogeneity. STUDY DESIGN, SIZE, DURATION: Prospective multicentre cohort study performed in 12 hospitals in three countries between 2012 and 2019. PARTICIPANTS/MATERIALS, SETTING, METHODS: All consecutive pregnant women with recurrent PL (≥3 losses or 2 losses in the presence of at least one euploid foetal karyotype) or at least one IUFD. Eligible women may have undergone thrombophilia testing before conception, at the discretion of local providers. The possible assignment of women to treatments (such as LMWH) was not decided a priori but was determined based on the responsible provider's current practice. Aims of the study were: (i) to evaluate factors associated with pregnancy outcome; (ii) to compare clinical management strategies in women with and without a subsequent successful pregnancy; and (iii) to evaluate characteristics of women who may benefit from antithrombotic therapy. A propensity score matching method was used to balance the differences in baseline characteristics. MAIN RESULTS AND THE ROLE OF CHANCE: A matched sample of 265 pregnant women was analysed, with all undergoing thrombophilia screening; 103 out of 119 (86.6%) with and 98/146 (67.1%) without thrombophilia were prescribed with LMWH and/or ASA. Overall, live-births were recorded in 204 cases (77%), PL or IUFD in 61 (23%) pregnancies. Logistic regression showed a significant interaction between thrombophilia and treatment with LMWH (P = 0.03). Findings from sensitivity analysis showed odds ratio (OR) for pregnancy loss in women with inherited or acquired thrombophilia in absence of any treatment was 2.9 (95% CI, 1.4-6.1); the administration of LMWH (with or without ASA) was associated with higher odds of live-birth (OR, 10.6; 95% CI, 5.0-22.3). Furthermore, in women without thrombophilia, the odds of live-birth was significantly and independently associated with LMWH prophylaxis (alone or in association with ASA) (OR, 3.6; 95% CI, 1.7-7.9). LIMITATIONS, REASONS FOR CAUTION: While the propensity score matching allows us to balance the differences in baseline characteristics, it does not eliminate all confounding. WIDER IMPLICATIONS OF THE FINDINGS: Antithrombotic prophylaxis during pregnancy may be effective in women with otherwise unexplained PL or IUFD, and even more useful in those with thrombophilia.

"APS pregnancy - The offspring".

BACKGROUND: Antiphospholipid antibody syndrome (APS) is an autoimmune disease that affects women in childbearing age. In recent years, great improvements were achieved in the management of pregnancies in these women. Prematurity could be an issue in these pregnancies, mainly due to the direct pathogenic effect of antiphospholipid antibodies (aPL) on the placental surface. Maternal IgG aPL can cross the placenta and theoretically interact with the growing fetus; it could reach the fetal brain because of the incompleteness of the fetal blood-brain barrier: whether this can have an effect on brain development is still debated. Neonatal thrombosis episodes have been described in children positive for aPL, not always associated with maternal antibody positivity, suggesting the hypothesis of a possible aPL de novo synthesis in fetus and neonates. METHODS: A keyword-based literature search was conducted. We also described a case of neonatal catastrophic antiphospholipid syndrome (CAPS). RESULTS: Offspring of patients with APS are generally healthy but the occurrence of neonatal thrombosis or minor neurological disorders were reported. CONCLUSIONS: The limited number of the available data on this sensitive issue supports the need for further studies. Clinical follow-up of children of mothers with APS seems to be important to exclude, in the neonatal period, the occurrence of aPL associated pathological events such as thrombosis, and in the long-term, impairment in learning skills or behavioral problems.

Labor induction with misoprostol vaginal insert compared with dinoprostone vaginal insert.

INTRODUCTION: Misoprostol vaginal insert could lead to a significant reduction in the time to vaginal delivery, and an increase in the proportion of women achieving vaginal delivery, compared with dinoprostone vaginal insert. We compared the delivery outcomes of misoprostol 200 µg vaginal insert and dinoprostone 10 mg vaginal insert for induction of labor in women with an unfavorable cervix. MATERIAL AND METHODS: This is a retrospective observational study conducted on a cohort of 220 women with a Bishop score ≤4 admitted for induction of labor at a single institution. Of these, 109 (49.5%) received the misoprostol vaginal insert and 111 (50.5%) received the dinoprostone vaginal insert. The primary outcome was the vaginal delivery rate. Secondary outcomes were time from induction to vaginal delivery, time to any delivery mode, time from induction to the onset of active labor, oxytocin use, uterine tachysystole and need for tocolysis. RESULTS: The vaginal delivery rate was 88% in the misoprostol insert group, compared with 74% in the dinoprostone insert group (P < 0.007). The average time from drug administration to the beginning of labor was shorter in the misoprostol compared with the dinoprostone group (855 min vs 1740 min, P < 0.0001). Also, the average time from administration to delivery was shorter for women receiving misoprostol compared with dinoprostone (1113 min vs 2150 min, P < 0.0001). The use of misoprostol reduced the need for oxytocin compared with dinoprostone (30.2% vs 43.2%, P = 0.046). Finally, compared with dinoprostone, the misoprostol insert was associated with more uterine tachysystole (38% vs 12%, P < 0.001), but the rate of tachysystole requiring tocolysis was not significantly different between the 2 groups (51.2% vs 46.1%, P = 0.1). Multivariate analysis showed that Bishop score and method of induction, but not maternal body mass index or gestational age at induction, were independently associated with mode of delivery. CONCLUSIONS: The cesarean section rate was significantly lower in the misoprostol insert group. The use of misoprostol was also associated with reduced time to vaginal delivery and time to onset of active labor and with decreased use of oxytocin. Tachysystole was a frequent complication during induction of labor with the misoprostol insert.

Rationale and design of two prospective, multicenter, observational studies on reproductive outcome in women with recurrent failures after spontaneous or assisted conception: OTTILIA and FIRST registries.

BACKGROUND: Spontaneous pregnancy loss and implantation failure after assisted reproductive technologies (ART) are very common occurrences. Although 50-60% of all cases remains unexplained, various predisposing factors, including thrombophilias, have been identified. Thus, the potential benefit of a prophylaxis with low-molecular-weight heparins in improving outcomes has been often investigated over the years. However, the majority of studies are observational and results from randomized clinical trials (RCTs) are inconclusive, probably due to heterogeneity and limited sample size. To cover these unmet needs and to have further data mainly based on the real-life clinical management, we designed these multicenter registries. METHODS: OTTILIA (Observational sTudy on antiThrombotic prevention in thrombophILIA and pregnancy loss) and FIRST (recurrent Failures in assIsted Reproductive Techniques) registries are two prospective, multicenter, observational studies to evaluate pregnancy or ART outcomes in consecutive women with previous reproductive failures after spontaneous or assisted conception, respectively. All enrolled women are observed from their first visit after positive pregnancy test (OTTILIA) or before commencing a new ART cycle (FIRST) until the end of pregnancy or ART procedure (negative pregnancy test/end of pregnancy, if successful cycle), respectively. Data are collected by means of questionnaires and recorded in a central database. Follow-up investigations are performed during hospital stay, routine clinical follow-up visits or telephone interviews. Primary outcome is live birth rate in the OTTILIA register and clinical pregnancy rate in the FIRST. DISCUSSION: Although RCTs are the 'gold standard' for evaluating treatment outcomes, we believe that our registries represent a valid alternative in improving knowledge on mechanisms involved in reproductive failures and supporting future clinical decisions. TRIAL REGISTRATION: NCT02385461 , retrospectively registered 5 March 2015 (OTTILIA); NCT02685800 , registered 10 February 2016 (FIRST).

A comprehensive review of the clinical approach to pregnancy and systemic lupus erythematosus.

Nowadays, most of the young women affected by Systemic Lupus Erythematosus (SLE) can carry out one or more pregnancies thanks to the improvement in treatment and the consequent reduction in morbidity and mortality. Pregnancy outcome in these women has also greatly improved in the last decades. A correct timing for pregnancy (tailored on disease activity and established during a preconception counselling), together with a tight monitoring during the three trimesters and the post-partum period (to timely identify and treat possible obstetric complications or maternal disease flares), as well as the concept of multidisciplinary management, are currently milestones of the management of pregnancy in SLE patients. Nevertheless, the increasing knowledge on the compatibility of drugs with pregnancy has allowed a better treatment of these patients, by choosing medications that control maternal disease activity without harming the foetus. However, particular attention and strict monitoring should be dedicated to SLE pregnant women in particular clinical settings: patients with lupus nephritis and patients with aPL positivity or Antiphospholipid syndrome, who are at higher risk for maternal and foetal complications, but also patients with anti-Ro/SSA and/or anti-La/SSB antibodies, because of the risk of neonatal lupus. A discussion on family planning, as well as counselling on contraception, should be part of the everyday-practice for physicians caring for SLE women during their reproductive age. Another issue is the possible reduction of fertility in these women, that can be due to different reasons. Consequently, the request for assisted reproduction techniques has been increasing in the last years, so that rheumatologists and gynaecologists should be prepared to counsel SLE patients also in this particular setting.

Prospectively-followed pregnancies in patients with inflammatory arthritis taking biological drugs: an Italian multicentre study.

OBJECTIVES: Information on new drugs does not include their possible effects on pregnancy because pregnant women are excluded from clinical trials. Although not classified as teratogenic in animals, limited data is available on biological anti-rheumatic agents and their safety in human pregnancy. The aim of the study is to evaluate the safety of biological drugs in pregnant patients with chronic arthritis. METHODS: Pregnancy outcome and maternal disease variations were prospectively followed in six Italian Rheumatology Centres. Patients exposed to biological agents during the periconceptional period or during pregnancy were included in the study. The occurrence of congenital malformations as well as the obstetric and neonatal outcomes were assessed. RESULTS: Between 1999 and 2013 we identified 79 exposed pregnancies in 67 women affected by different rheumatic diseases with peripheral chronic arthritis. At the time of the start of pregnancy, 56 patients were taking etanercept, 13 adalimumab, 3 infliximab, 2 each certolizumab-pegol and rituximab, 1 each golimumab, anakinra and abatacept. Biological treatment was stopped after a mean of 41 days since documented pregnancy. Live births were reported in 66% of pregnancies. The rate of spontaneous pregnancy loss was 20%. Only one congenital malformation was reported. CONCLUSIONS: TNF-alpha inhibitors can be considered safe in the periconception period, representing a possible therapeutic choice also in young women affected by an aggressive form of chronic arthritis and hoping for a pregnancy. Reports of exposure during 2nd/3rd trimester are still limited and suggest caution. Experience with abatacept, tocilizumab, anakinra and rituximab in pregnancy is insufficient.

The role of second trimester uterine artery Doppler in pregnancies with systemic lupus erythematosus.

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.

Prophylactic oral nifedipine to reduce preterm delivery: a randomized controlled trial in women at high risk.

OBJECTIVE: To establish the efficacy of prophylactic nifedipine vs. placebo in reducing spontaneous preterm delivery in asymptomatic women at high risk for preterm delivery. DESIGN: Prospective multicentric randomized double-blind study. SETTING: Tertiary care centre, University Hospitals of Brescia and Torino, Italy. POPULATION: Eighty-seven singleton pregnancies without uterine contractions and ultrasonographic cervical length of ≤25 mm at 24-32 weeks, at risk for preterm delivery, with longitudinal follow up in our Preterm Prevention Clinic. METHODS: Selection was done on the basis of ultrasonographic cervical length; 43 women were randomized to receive placebo and 44 to receive nifedipine. MAIN OUTCOME MEASURES: Primary end point: spontaneous preterm delivery <37 weeks in nifedipine vs. placebo. SECONDARY OUTCOMES: delivery <32 weeks, maternal side effects, neonatal complications, admissions to the Neonatal Intensive Care Unit and randomization/delivery time in nifedipine vs. placebo. RESULTS: There was no trend towards a lower risk of spontaneous preterm delivery, neither at <37 weeks of nifedipine vs. placebo (11.4% vs. 19.0%; p = 0.320), or <32 weeks (2.3% vs. 2.4%; p = 0.973). Nifedipine reduced spontaneous preterm delivery <37 weeks (p = 0.015) in the multiparous women by stratified analysis for parity. SECONDARY OUTCOMES between the groups did not differ except for a higher percentage of maternal side-effects in the nifedipine group (31.8%) vs. placebo (11.9%) (p < 0.05). Subgroup analysis showed a borderline (p = 0.047) lower percentage of spontaneous preterm delivery in women with a ultrasonographic cervical length of <20 mm in the nifedipine group. CONCLUSIONS: Prophylactic nifedipine in asymptomatic women at high risk for preterm delivery had a positive effect on the rate of spontaneous preterm delivery <37 weeks in multiparous women.

Novel aspects of Sjögren's syndrome in 2012.

Sjögren's syndrome (SS) is a systemic progressive autoimmune disease characterized by a complex pathogenesis requiring a predisposing genetic background and involving immune cell activation and autoantibody production. The immune response is directed to the exocrine glands, causing the typical 'sicca syndrome', but major organ involvement is also often seen. The etiology of the disease is unknown. Infections could play a pivotal role: compared to normal subjects, patients with SS displayed higher titers of anti-Epstein-Barr virus (EBV) early antigens, but lower titers of other infectious agent antibodies such as rubella and cytomegalovirus (CMV) suggest that some infections may have a protective role against the development of autoimmune disease. Recent findings seem to show that low vitamin D levels in patients with SS could be associated with severe complications such as lymphoma and peripheral neuropathy. This could open new insights into the disease etiology. The current treatments for SS range from symptomatic therapies to systemic immunosuppressive drugs, especially B cell-targeted drugs in cases of organ involvement. Vitamin D supplementation may be an additional tool for optimization of SS treatment.

European registry of babies born to mothers with antiphospholipid syndrome.

OBJECTIVES: This study aimed to describe the long-term outcome and immunological status of children born to mothers with antiphospholipid syndrome, to determine the factors responsible for childhood abnormalities, and to correlate the child's immunological profile with their mothers. METHODS: A prospective follow-up of a European multicentre cohort was conducted. The follow-up consisted of clinical examination, growth data, neurodevelopmental milestones and antiphospholipid antibodies (APL) screening. Children were examined at 3, 9, 24 months and 5 years. RESULTS: 134 children were analysed (female sex in 65 cases, birth weight 3000±500 g, height 48±3 cm). Sixteen per cent had a preterm birth (<37 weeks; n=22), and 14% weighted less than 2500 g at birth (n=19). Neonatal complications were noted in 18 cases (13%), with five infections (4%). During the 5-year follow-up, no thrombosis or systemic lupus erythematosus (SLE) was noted. Four children displayed behavioural abnormalities, which consisted of autism, hyperactive behaviour, feeding disorder with language delay and axial hypotony with psychomotor delay. At birth lupus anticoagulant was present in four (4%), anticardiolipin antibodies (ACL) IgG in 18 (16%), anti-ß(2) glycoprotein-I (anti-ß2GPI) IgG/M in 16 (15%) and three (3%), respectively. ACL IgG and anti-ß2GPI disappeared at 6 months in nine (17%) and nine (18%), whereas APL persisted in 10% of children. ACL and anti-ß2GPI IgG were correlated with the same mother's antibodies before 6 months of age (p<0.05). CONCLUSION: Despite the presence of APL in children, thrombosis or SLE were not observed. The presence of neurodevelopmental abnormalities seems to be more important in these children, and could justify long-term follow-up.

Brief report: successful pregnancies but a higher risk of preterm births in patients with systemic sclerosis: an Italian multicenter study.

OBJECTIVE: To assess fetal and maternal outcomes in women with systemic sclerosis (SSc). METHODS: Prospectively collected data on 99 women with SSc from 25 Italian centers were analyzed retrospectively. Women with SSc were observed during 109 pregnancies (from 2000 to 2011), and outcomes were compared to those in the general obstetric population (total of 3,939 deliveries). The maternal age at conception was a mean ± SD 31.8 ± 5.3 years, and the median disease duration at conception was 60 months (range 2-193 months). RESULTS: SSc patients, compared to the general obstetric population, had a significantly increased frequency of preterm deliveries (25% versus 12%) and severe preterm deliveries (<34 weeks of gestation) (10% versus 5%), intrauterine growth restriction (6% versus 1%), and babies with very-low birth weight (5% versus 1%). Results of multivariable analysis showed that corticosteroid use was associated with preterm deliveries (odds ratio [OR] 3.63, 95% confidence interval [95% CI] 1.12-11.78), whereas the use of folic acid (OR 0.30, 95% CI 0.10-0.91) and presence of anti-Scl-70 antibodies (OR 0.26, 95% CI 0.08-0.85) were protective. The disease remained stable in most SSc patients, but there were 4 cases of progression of disease within 1 year from delivery, all in anti-Scl-70 antibody-positive women, 3 of whom had a disease duration of <3 years. CONCLUSION: Women with SSc can have successful pregnancies, but they have a higher-than-normal risk of preterm delivery, intrauterine growth restriction, and babies with very-low birth weight. Progression of the disease during or after pregnancy is rare, but possible. High-risk multidisciplinary management should be standard for these patients, and pregnancy should be avoided in women with severe organ damage and postponed in women with SSc of recent onset, particularly if the patient is positive for anti-Scl-70 antibodies.

Induction of Labor in Women with Previous Cesarean Section and Unfavorable Cervix: A Retrospective Cohort Study.

Background: The efficacy and safety of a cervical ripening balloon (CRB) in women with a previous cesarean section (CS) and unfavorable Bishop score are still controversial. Methods: A retrospective cohort study was performed across six tertiary hospitals from 2015 to 2019. Women with one previous transverse CS, singleton cephalic term pregnancy and BS < 6 were included if submitted to labor induction with a CRB. The main outcome was the rate of vaginal birth after cesarean (VBAC) after CRB ripening. Secondary outcomes were abnormal composite fetal and maternal outcomes. Results: Of the 265 women included, 57.3% had successful vaginal birth. Augmentation improved vaginal delivery (32.2% vs. 21.2%). Intrapartum analgesia was associated with an increased VBAC rate (58.6% vs. 34.5%). Maternal BMI ≥30 and age ≥40 years increased emergency CS rate (11.8% vs. 28.3% and 7.2 vs. 15.9%). Composite adverse maternal outcome occurred in 4.8% of CRB group women and increased to 17.6% when associated with oxytocin. Uterine rupture occurred in one case (0.4%) in the CRB-oxytocin group. Poorer fetal outcome occurred after emergency CS, if compared to successful VBAC (12.4% vs. 3.3%). Conclusions: In women with a previous CS and unfavorable Bishop score, induction of labor with a CRB can be considered safe and effective.

Reproductive Issues and Pregnancy Implications in Systemic Sclerosis.

Systemic sclerosis (SSc) is a rare systemic autoimmune disease that can influence reproductive health. SSc has a strong female predominance, and the disease onset can occur during fertility age in almost 50% of patients. Preconception counseling, adjustment of treatment, and close surveillance during pregnancy by a multidisciplinary team, are key points to minimize fetal and maternal risks and favor successful pregnancy outcomes. The rates of spontaneous pregnancy losses are comparable to those of the general obstetric population, except for patients with diffuse cutaneous SSc and severe internal organ involvement who may carry a higher risk of abortion. Preterm birth can frequently occur in women with SSc, as it happens in other rheumatic diseases. Overall disease activity generally remains stable during pregnancy, but particular attention should be paid to women with major organ disease, such as renal and cardiopulmonary involvement. Women with such severe involvement should be thoroughly informed about the risks during pregnancy and possibly discouraged from getting pregnant. A high frequency of sexual dysfunction has been described among SSc patients, both in females and in males, and pathogenic mechanisms of SSc may play a fundamental role in determining this impairment. Fertility is overall normal in SSc women, while no studies in the literature have investigated fertility in SSc male patients. Nevertheless, some considerations regarding the impact of some immunosuppressive drugs should be done with male patients, referring to the knowledge gained in other rheumatic diseases.

Pregnancy implications for systemic lupus erythematosus and the antiphospholipid syndrome.

Multidisciplinary approach and patient counselling have been the key points in the improvement of the management of pregnancy in women with systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). Most of these women can have successful pregnancy when thoroughly informed and instructed on several different issues. Disease activity should be in stable remission prior to pregnancy in order to reduce the chance for flare during pregnancy. To this purpose, medications must be modulated: "safe" drugs should be continued throughout pregnancy, embryotoxic/foetotoxic drugs should be withdrawn timely, and beneficial drugs such as low dose aspirin and heparin should be added for prophylaxis of maternal and foetal outcome, especially in the presence of antiphospholipid antibodies. The safety profile of anti-rheumatic drugs during pregnancy and breastfeeding should be kept constantly updated, as new data from inadvertent exposure accumulates and new drugs (especially biological agents) are available. Patients may carry autoantibodies that can negatively affect the baby, being neonatal lupus the prototypical case of passively acquired autoimmunity. Research has been greatly active in this field and more information on risk stratification and management are now available for counselling. The effect of both autoantibodies and drug exposure has been evaluated in the offspring: some concerns about learning disabilities have been raised, but these are treatable conditions that are likely to be overcome. To counsel a woman with SLE/APS during childbearing age means also to deal with contraception. Despite the "preferred choice" - combined oral contraceptive - may not be suitable for most of the patients, other options are available and should be offered and discussed with the patient. Fertility is not generally affected in SLE/APS patients, but those cases who require assisted reproduction techniques should be carefully evaluated and managed.

Stopping bDMARDs at the beginning of pregnancy is associated with disease flares and preterm delivery in women with rheumatoid arthritis.

Objectives: Women with Rheumatoid Arthritis (RA) can experience flares during pregnancy that might influence pregnancy outcomes. We aimed at assessing the disease course during pregnancy and identifying risk factors for flares. Methods: Data about prospectively-followed pregnancies in RA were retrospectively collected before conception, during each trimester and in the post-partum period. Clinical characteristics, disease activity (DAS28-CRP3), medication use, and pregnancy outcomes were analysed with regard to disease flares. Results: Among 73 women who had a live birth, 64 (88%) were in remission/low disease activity before conception. During pregnancy, a flare occurred in 27 (37%) patients, mainly during first and second trimester. Flares during pregnancy were associated with the discontinuation of bDMARDs at positive pregnancy test (55% of patients with flare vs. 30% of patients with no flare, p 0.034, OR 2.857, 95% CI 1.112-8.323) and a previous use of >1 bDMARDs (33% of patients with flare vs. 10% of patients with no flare, p 0.019, OR 4.1, 95%CI 1.204-13.966). Preterm pregnancies were characterised by higher values of CRP [10 mg/L (5-11) vs. 3 mg/L (2.5-5), p 0.01] and DAS28-CRP3 [4.2 (1.9-4.5) vs. 1.9 (1.7-2.6), p 0.01] during the first trimester as compared with pregnancies at term. Preterm delivery was associated with the occurrence of flare during pregnancy (flare 27% vs. no-flare 7%, p 0.034, OR 4.625, 95%CI 1.027-20.829). Conclusion: Preterm delivery in RA patients was associated with flares during pregnancy. Flares occurred more frequently after the discontinuation of bDMARDs at positive pregnancy test. Women with aggressive RA on treatment with bDMARDs should be considered as candidates for continuing bDMARDs during pregnancy in order to reduce the risk of flare and adverse pregnancy outcomes.

Anti-ß2-glycoprotein I IgG antibodies from 1-year-old healthy children born to mothers with systemic autoimmune diseases preferentially target domain 4/5: might it be the reason for their 'innocent' profile?

BACKGROUND: Anti-ß2-glycoprotein-I (anti-ß2GPI) were demonstrated to be pathogenic in the antiphospholipid syndrome (APS). However, they can be detected in patients with no features of APS, especially those affected by systemic autoimmune diseases (SAD), and so in healthy children. It has been suggested that anti-ß2GPI against domain 1 (D1) associate with thrombosis, while those recognising domain 4/5 (D4/5) are present in non-thrombotic conditions. OBJECTIVE: To evaluate the fine specificity of anti-ß2GPI in adults and infants. METHODS: Three groups were examined-group A: 57 1-year-old healthy children born to mothers with SAD; group B: 33 children with atopic dermatitis; group C: 64 patients with APS. SUBJECTS: were selected based on positive anti-ß2GPI IgG results. Serum samples were tested for anti-ß2GPI IgG D1 and D4/5 using research ELISAs containing recombinant ß2GPI domain antigens. RESULTS: Children (A and B) displayed preferential IgG reactivity for D4/5, whereas patients with APS were mainly positive for D1. No thrombotic events were recorded in groups A and B. CONCLUSIONS: The specificity for D4/5 suggests that anti-ß2GPI IgG production in children born to mothers with SAD is a process neither linked to systemic autoimmunity nor related to the maternal autoantibody status. This unusual fine specificity might, at least partially, account for the 'innocent' profile of such antibodies.

Disease course and obstetric outcomes of pregnancies in juvenile idiopathic arthritis: are there any differences among disease subtypes? A single-centre retrospective study of prospectively followed pregnancies in a dedicated pregnancy clinic.

To study disease activity during pregnancy and obstetric outcomes in patients with juvenile idiopathic arthritis (JIA) upon different subsets and with focus on medication use. Retrospective observational study of 22 pregnancies in 16 JIA patients (95.5% Caucasian) who were followed between 2010 and 2018. Disease activity, flares and medications were recorded before conception, during each trimester and postpartum period. Pregnancies occurred in 10 (45.5%) oligoarticular extended (OLA-E), 6 (27.3%) in polyarticular (PLA), 4 in (18.2%) systemic (SYS), 1 (4.5%) in oligoarticular persistent (OLA-P) and 1 (4.5%) in enthesitis-related arthritis (ERA) JIA patients. The median age at disease diagnosis and at conception was 5.5 and 28 years (respectively). The median disease duration was 20 years. Nineteen (95%) pregnancies started in a period of stable disease remission. Among the 22 pregnancies, 20 ended with a live birth (90.9%). No spontaneous miscarriages occurred; two voluntary interruption of pregnancy were performed. There were 7 flares in 6/20 pregnancies (35%) and 8 flares (8/22, 36.4%) occurred in postpartum period, all of them in OLA-E and PLA patients. Seven patients (35%) were taking biological disease-modifying anti-rheumatic drugs (bDMARDs) at conception, and 6 of them stopped this treatment at positive pregnancy test. Five patients resumed bDMARDs either during pregnancy (3 exposed during the third trimester) or puerperium due to a flare. Four preterm deliveries (20%) were recorded, all in patients who had a flare during pregnancy. The preconception counselling should include the evaluation of disease subset, as OLA-E and PLA may flare more than other subsets, especially if bDMARDs are discontinued at positive pregnancy test. Continuation of bDMARDs during pregnancy should be considered to minimize the risk of adverse pregnancy outcomes, particularly preterm delivery. Key Points • In our cohort, all the flares during pregnancy and 75% of postpartum flares were observed in patients who withdrew bDMARDs and cDMARDs at the beginning of pregnancy. • Flares were observed only in PLA and OLA-E patients. • Preterm delivery occurred in 20% of the pregnancies; all of these patients had a disease flare during pregnancy.
