Abstract
Maternal autoimmune rheumatic diseases can influence the outcomes of children through several life stages. During pregnancy, maternal inflammation and autoantibodies can hinder fetal development and lead to growth restriction, preterm birth, and low birth weight; prematurity, especially at extreme gestational ages, can in turn impair future child health. Treatment with compatible immunomodulatory drugs and preventive medications aims to keep maternal disease under control and minimise the risk of adverse pregnancy outcomes. However, concerns have been raised about the effects of immunomodulatory drugs on neonatal conditions (ie, the risk of serious infections, inadequate responses to vaccinations, and organ toxicity) and long-term outcomes (metabolic and cardiovascular problems and neurodevelopmental disorders). Among the unmet needs of parents with autoimmune rheumatic diseases, there is the estimation of risk for the children to develop autoimmune disorders and the need for reassurance about parenting capacity while living with a chronic condition. This Series paper provides a comprehensive overview of the literature and guidance on discussing these topics with patients.

Abstract
Background Autoimmune diseases encompass a diverse array of disorders that disturb the optimal functioning of the immune system, which is to eliminate the 'foreign or/and dangerous' to mistakenly target the body's own tissues. Objective The aim of this research is to evaluate the most effective approach to managing autoimmune diseases within the framework of pregnancy. Methods The exact causes and etiologies of these diseases are multifactorial and mostly still unclear. Ro/SSA autoantibodies and La/SSB, could be found in Sjögren's disease (SJ), systemic lupus (SLE) and other autoimmune disorders. Smoking, stress, UV exposure, vitamin D deficiency, and other genetic and environmental factors have been identified as risk factors for rheumatic diseases. Results Over the years, an ever-increasing incidence of these diseases has been observed in the general population, with the female sex being at increased risk for their occurrence. This fact raises the question of what should be the management of these pathological entities during pregnancy. Taking into account the very significant impact on the quality of paitients'daily life and the seemingly augmented prevalence of autoimmune diseases, as well as their preference in the female population, the reasonable question arises as to what should be the optimal management of these diseases in the context of pregnancy. Conclusion Given the limited data of the global medical community regarding the etiological factors and mechanisms that trigger the onset of rheumatic diseases, the management of pregnant women is a complex conundrum that health professionals are challenged to face and solve.

Abstract
This international multidisciplinary expert consensus statement is intended to provide comprehensive guidance that can be referenced at the point of care to cardiac electrophysiologists, cardiologists, and other health care professionals, on the management of cardiac arrhythmias in pregnant patients and in fetuses. This document covers general concepts related to arrhythmias, including both brady- and tachyarrhythmias, in both the patient and the fetus during pregnancy. Recommendations are provided for optimal approaches to diagnosis and evaluation of arrhythmias; selection of invasive and noninvasive options for treatment of arrhythmias; and disease- and patient-specific considerations when risk stratifying, diagnosing, and treating arrhythmias in pregnant patients and fetuses. Gaps in knowledge and new directions for future research are also identified.

Abstract
OBJECTIVES Most women may have temporary pain for which they use analgesics, but those with autoimmune disorders have chronic pain that may be exacerbated for some during pregnancy. This study aimed to determine whether prenatal acetaminophen use was associated with an increased risk of adverse pregnancy and birth outcomes in women with autoimmune disorders. METHODS Participants were enrolled between 2004 and 2018 in the MotherToBaby cohort study and limited to women with an autoimmune disorder (n = 1,821). Self-reported acetaminophen use was characterized over gestation for indication, timing of use and duration. Cumulative acetaminophen use through 20 and 32 weeks was categorized into quintiles, with no acetaminophen use as the reference category. The association between acetaminophen quintile and preeclampsia or pregnancy induced hypertension, small for gestational age (SGA), and preterm birth was examined using adjusted multiple log-linear regression. RESULTS Overall, 74% of women reported acetaminophen use during pregnancy. The most often reported indication for using acetaminophen was headache/migraines, followed by pain and injury. Risk of preeclampsia was 1.62 times greater for those in the fifth quintile of cumulative acetaminophen use through 20 weeks compared with those with no acetaminophen use (95% CI: 1.10, 2.40). There were no associations with lower use quintiles, nor for the other outcomes. CONCLUSION The highest quintile of cumulative acetaminophen was associated with a modestly increased risk for preeclampsia. Some women with autoimmune conditions have pain throughout pregnancy; clinicians and patients should discuss approaches to best avoid high levels of acetaminophen in their pain management strategies.

Abstract
OBJECTIVES To compare cardiac function and systolic dyssynchrony of fetuses not exposed to and those exposed to maternal autoimmune antibodies using two-dimensional speckle tracking echocardiography (2DSTE). METHODS An observational study of 52 fetuses, 18 from mothers with autoimmune antibodies (anti-SSA/Ro60, anti-Ro52 or/and anti-SSB/La) and 34 from healthy mothers without antibodies, was conducted. Maternal baseline characteristics, fetoplacental Doppler parameters, and conventional echocardiographic data were prospectively collected. Systolic global and regional longitudinal strain of left and right ventricle (LV and RV) and the time to peak strain of regional myocardium were measured using 2DSTE. We also calculated the differences in time to peak strain between the LV free wall and RV free wall (two-chamber dyssynchrony, 2C-DYS) and the LV dyssynchrony between the septum and LV free wall (one-chamber dyssynchrony, 1C-DYS). RESULTS There were no significant differences in conventional systolic and diastolic functional parameters for the LV and RV. No effect modification was demonstrated in a myocardial deformation analysis. However, 1C-DYS was significantly more prolonged in the maternal autoimmune disease group (19.50 [8.00 to 29.25] vs. 28.50 [13.50 to 39.25], P = 0.042). CONCLUSIONS LV systolic mechanical dyssynchrony in fetuses of mothers with autoimmune antibodies suggests in-utero subclinical damage of the cardiac conduction system. Key points • The left ventricular systolic dyssynchrony was significantly more prolonged in the maternal autoimmune disease (AD) fetuses. • Subclinical damage to the left ventricular conduction system of the fetal heart in maternal AD was observed. • Systolic and diastolic functional of the left and right ventricle were preserved in fetuses exposed to maternal autoimmune disease.

Abstract
Introduction: Systemic lupus erythematosus (SLE) mainly affects young females during childbearing age; therefore, reproductive issues are of major interest.Areas covered: Pregnancy planning is crucial to adjust the treatment toward drugs that are safe throughout pregnancy and breastfeeding. The evidence about drug safety is limited to post-marketing surveillance, registries, case series, and case reports, as pregnant patients are excluded from randomized clinical trials. The aim of this review is to report the safety considerations when treating pregnant SLE patients. Regarding maternal side effects of drugs, we focused on metabolic, infectious, and hemorrhagic complications. Fetal safety was analyzed looking at drugs teratogenicity, their possible effects on immune system, and on the long-term neuropsychological development of children.Expert opinion: The management of pregnancy in SLE has changed when knowledge about the safety of drugs has become available. Keeping SLE disease activity under control before, during and after pregnancy is of fundamental importance to ensure the best possible outcomes for mother and child. All these issues must be discussed with the patient and her family during preconception counseling. International efforts in terms of pregnancy registries and reproductive health guidelines help physicians improve their communication with SLE patients.

Abstract
Autoimmune thyroid disease is the most common endocrine disorder during pregnancy. Thyroid autoantibodies (TAs) have been suggested to serve a role in implantation failure and spontaneous abortion. Until now, there are no data on the potential interaction of TAs with human reproductive organs. Here, we set out for the first time to test this hypothesis by studying the expression of thyroid peroxidase (TPO) at gene and protein level in human reproductive organs. Endometrial samples were taken from normal women, and placenta tissues were collected after full-term caesarian section. Expression of TPO messenger RNA (mRNA) was investigated by qRT-PCR. In addition, polyclonal anti-TPO antibodies were produced and the expression of TPO protein in mentioned tissues was evaluated by immunohistochemistry and Western blot analysis. The reactivity of anti-TPO antibody in human embryos was evaluated by immunofluorescent staining. For the first time, our study showed that TPO is expressed at gene and protein levels in endometrium and placenta. TPO expression was mainly localized to glandular and luminal epithelial cells in the endometrium. In placenta, the syncytiotrophoblasts and invasive trophoblast cells were the main cell types that expressed TPO protein. Specific band of approximately 110 kDa was observed in all endometrial and placental tissues by Western blot analysis. However, no expression of TPO protein was observed in human embryo. TPO expression in endometrium and placenta may explain higher frequency of abortion and infertility in patients with thyroid autoimmunity.

Abstract
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. TAKE HOME MESSAGES.

Abstract
UNLABELLED Maternal inflammation during pregnancy affects placental function and is associated with increased risk of neurodevelopmental disorders in the offspring. The molecular mechanisms linking placental dysfunction to abnormal fetal neurodevelopment remain unclear. During typical development, serotonin (5-HT) synthesized in the placenta from maternal l-tryptophan (TRP) reaches the fetal brain. There, 5-HT modulates critical neurodevelopmental processes. We investigated the effects of maternal inflammation triggered in midpregnancy in mice by the immunostimulant polyriboinosinic-polyribocytidylic acid [poly(I:C)] on TRP metabolism in the placenta and its impact on fetal neurodevelopment. We show that a moderate maternal immune challenge upregulates placental TRP conversion rapidly to 5-HT through successively transient increases in substrate availability and TRP hydroxylase (TPH) enzymatic activity, leading to accumulation of exogenous 5-HT and blunting of endogenous 5-HT axonal outgrowth specifically within the fetal forebrain. The pharmacological inhibition of TPH activity blocked these effects. These results establish altered placental TRP conversion to 5-HT as a new mechanism by which maternal inflammation disrupts 5-HT-dependent neurogenic processes during fetal neurodevelopment. SIGNIFICANCE STATEMENT The mechanisms linking maternal inflammation during pregnancy with increased risk of neurodevelopmental disorders in the offspring are poorly understood. In this study, we show that maternal inflammation in midpregnancy results in an upregulation of tryptophan conversion to serotonin (5-HT) within the placenta. Remarkably, this leads to exposure of the fetal forebrain to increased concentrations of this biogenic amine and to specific alterations of crucially important 5-HT-dependent neurogenic processes. More specifically, we found altered serotonergic axon growth resulting from increased 5-HT in the fetal forebrain. The data provide a new understanding of placental function playing a key role in fetal brain development and how this process is altered by adverse prenatal events such as maternal inflammation. The results uncover important future directions for understanding the early developmental origins of mental disorders.

Low titer, isolated anti Ro/SSA 60 kd antibodies is correlated with positive pregnancy outcomes in women at risk of congenital heart block. Clin Rheumatol 2017; 36:1155-1160. [PMID: 28204891 DOI: 10.1007/s10067-017-3572-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2016] [Revised: 02/03/2017] [Accepted: 02/04/2017] [Indexed: 11/30/2022]
Abstract
Congenital heart block (CHB) is an autoantibody mediated disorder presumably caused by placental transmission of maternal autoantibodies to Ro/SSA 52 kd, p200, Ro/SSA 60 kd, La/SSB ribonucleoproteins. This study investigated the clinical significance of isolated anti-Ro/SSA 52 kd, anti-p200, anti-Ro/SSA 60 kd, and anti-La/SSB antibodies in positive pregnant patients. One hundred sixty-three pregnant women positive to anti-Ro/SSA 52 kd and/or anti-Ro/SSA 60 kd and/or anti-La/SSB antibodies were prospectively enrolled in the study. Anti-Ro52, anti-Ro60, anti-p200, and anti-La antibodies were assayed using home-made ELISA assays. Isolated antibody positivity was found in 25 women (15.3%), while multiple antibody positivity in 138 (84.7%). Twenty-four developed CHB, and the 139 had a favorable pregnancy outcome. The prevalence of isolated anti-Ro/SSA 60 kd antibodies was significantly higher (p < 0.046) as the prevalence of lower mean antibody titers (p < 0.0001) in the later group. Confirmation of these results by large-scale studies could lead clinicians to recommend less stringent fetal echocardiography monitoring in women with isolated anti-Ro/SSA 60 kd antibodies.

Abstract
Autoimmune diseases (AD) occur frequently in women during their childbearing years and may influence pregnancy outcome and neonatal health. Patients with systemic lupus erythematosus (SLE) can experience a disease flare-up during pregnancy with potential negative effects on the product of conceptus, especially if the disease is active. Recurrent pregnancy loss is now considered as a treatable clinical condition associated with the presence of circulating antiphospholipid antibodies (aPL). The neonatal lupus syndromes (NLS), caused by the transplacental passage of maternal IgG anti-Ro/SS-A and anti-La/SS-B antibodies to the fetus, carry significant morbidity and mortality in case of cardiac manifestations. Immunosuppressive agents are often administered during pregnancy in order to control maternal disease and to ensure a better pregnancy outcome. Nowadays, owing to our increasing knowledge of the disease pathophysiological mechanisms and the development of combined medical-obstetric clinics, pregnancy outcome in patients with AD has notably improved.

Abstract
Growing evidence points toward a critical role for early (prenatal) atypical neurodevelopmental processes in the aetiology of autism spectrum condition (ASC). One such process that could impact early neural development is inflammation. We review the evidence for atypical expression of molecular markers in the amniotic fluid, serum, cerebrospinal fluid (CSF), and the brain parenchyma that suggest a role for inflammation in the emergence of ASC. This is complemented with a number of neuroimaging and neuropathological studies describing microglial activation. Implications for treatment are discussed.

Abstract
BACKGROUND The increased number of childbearing women with autoimmune diseases leads to a growing interest in studying relationship among maternal disease, therapy, pregnancy and off-spring. The aim of this study was to determine the impact of autoimmune disease on pregnancy and on neonatal outcome, taking into account the maternal treatment and the transplacental autoantibodies passage. METHODS We studied 70 infants born to 70 pregnant women with autoimmune disease attended in Fondazione IRCCS Policlinico San Matteo, Pavia, Italy from June 2005 to June 2012. Maternal and neonatal characteristics were collected and relevant clinical, laboratory, therapeutics, sonographic and electrocardiographic investigations were recorded and analyzed. RESULTS We observed a high rate of spontaneous abortions in medical history, 29 %, and 18.6 % of preterm births and 22.9 % of low birth weight (< 2500 g). Transplacental autoantibodies passage wasn't related to maternal or obstetrical complication, but anti-Ro/SSA positive pregnancies correlated with abnormal fetal heart rate (P = 0.01). Pregnant women on therapy showed an higher incidence of maternal (p = 0.002), obstetric (p = 0.007) complications and an increased rate of intrauterine growth restriction (p = 0.01) than the untreated ones. CONCLUSIONS Autoimmune diseases in pregnancy require to be carefully monitored to ensure the best possible management of mothers, fetuses and newborns due to the high rate of morbidity specially in case of maternal polytherapy and/or anti-Ro/SSA positivity.

Abstract
Neonatal lupus erythematosus (NLE) refers to a clinical spectrum of cutaneous, cardiac, and systemic abnormalities observed in newborn infants whose mothers have autoantibodies against Ro/SSA and La/SSB. The condition is rare and usually benign and self-limited but sometimes may be associated with serious sequelae. We review the pathophysiology, clinical features, and management of infants with this condition. Neonates with NLE should be managed at a tertiary care center. Multidisciplinary team involvement may also be indicated. In mothers with anti-Ro/SSA and/or anti-La/SSB antibodies and infants with congenital heart block, the risk of recurrence in subsequent offspring is 17–25%. Therefore, careful monitoring of subsequent pregnancies with serial ultrasonography and echocardiography is essential.

Abstract
Autism spectrum disorders (ASD) are complex and heterogeneous with a spectrum of diverse symptoms. Mounting evidence from a number of disciplines suggests a link between immune function and ASD. Although the causes of ASD have yet to be identified, genetic studies have uncovered a host of candidate genes relating to immune regulation that are altered in ASD, while epidemiological studies have shown a relationship with maternal immune disturbances during pregnancy and ASD. Moreover, decades of research have identified numerous systemic and cellular immune abnormalities in individuals with ASD and their families. These include changes in immune cell number, differences in cytokine and chemokine production, and alterations of cellular function at rest and in response to immunological challenge. Many of these changes in immune responses are associated with increasing impairment in behaviors that are core features of ASD. Despite this evidence, much remains to be understood about the precise mechanism by which the immune system alters neurodevelopment and to what extent it is involved in the pathogenesis of ASD. With estimates of ASD as high as 1% of children, ASD is a major public health issue. Improvements in our understanding of the interactions between the nervous and immune system during early neurodevelopment and how this interaction is different in ASD will have important therapeutic implications with wide ranging benefits.

Abstract
BACKGROUND Vitiligo, characterized by destruction of melanocytes, causes a patchy depigmentation of the skin. It has been hypothesized to have an autoimmune pathogenesis. Autoimmune disorders are more common among women and may be associated with adverse pregnancy outcomes, such as recurrent abortions, intrauterine growth restriction (IUGR), and pre-eclampsia. OBJECTIVE The purpose of this study was to investigate whether patients with vitiligo have increased rates of gestational complications. METHODS A retrospective comparative study was undertaken comparing pregnancy complications of patients with and without vitiligo. The population was composed of all singleton deliveries that occurred at the Soroka University Medical Center in Israel during the years 1988-2006. Women lacking prenatal care and multiple gestations were excluded from the study. A multivariable logistic regression model was constructed to control for confounders. RESULTS Of 186,222 singleton deliveries, 79 (0.04%) were patients with vitiligo. Vitiligo was not found to be associated with adverse pregnancy outcomes, including obstetric risk factors, labor characteristics and complications, and birth outcome. Using multivariable analysis, only grand multiparity (above five deliveries) was independently associated with vitiligo (OR = 2.01; 95% CI 1.2-3.2; P = 0.007). LIMITATIONS Retrospective analysis was a limitation. CONCLUSION Vitiligo is not associated with adverse pregnancy outcomes. Accordingly, patients with vitiligo should not be managed differently from the general obstetric population.

Abstract
Background Systemic Lupus Erythematosus (SLE) has a tendency to occur in women in their reproductive years, causing complications during pregnancy and labour. Conversely, pregnancy can cause flares of disease activity, often necessitating immediate intervention. Aim of study to study pregnancy related complications in patients with SLE. Patients and methods The study included 48 SLE pregnant females. 27 patients with 38 pregnancies, their data viewed retrospectively from medical records, and 21 patients with 21 pregnancies followed up prospectively. The laboratory data included ANA, DNA, APL antibodies and anti Ro/SSA. The disease activity was calculated according to the Systemic Lupus Activity Measure. Ultrasound was performed to confirm gestational age and assess for the presence of any congenital fetal malformations, and then repeated monthly to detect any abnormality including intrauterine growth restriction. At 30 weeks gestation and onwards, assessment of fetal wellbeing including daily fetal kick chart and once weekly non stress test was performed. Doppler blood flow velocimetry was done for those with abnormal fetal heart rate pattern. After labour, the neonate was examined for complications including complete heart block and neonatal lupus. Results Anti dsDNA was found in 95% of the patients, anti Ro/SSA in 6% and anti APL in 30%. 57% of the patients followed up prospectively had active disease in the 1st trimester, 24% in the 2nd and 62% in the 3rd trimester. The most common maternal complication was preeclampsia 33%, followed by spontaneous abortion 20%. Prematurity was the most common fetal complication 37%, followed by intrauterine growth restriction 29%. 2 neonates were born with congenital heart block and 1 with neonatal lupus. Conclusion Pregnancy in SLE patients is associated with a higher risk of obstetric complications affecting both the mother and the fetus. Preeclampsia was the most common complication followed by prematurity. Preeclampsia was significantly associated with third trimester disease activity.

Abstract
Infertility and recurrent spontaneous abortion (RSA) are heterogeneous conditions that have been frequently explained with an immunological pathomechanism. A deeper insight into apparently unexplained infertility and RSA shows increasing evidences supporting both alloimmune and autoimmune mechanisms, in which natural killer (NK) cells and autoantibodies seem to play a relevant role. Successful pregnancy is considered as Th1-Th2 cooperation phenomenon, with a predominantly Th2-type lymphocytes response, together with the emerging role of interleukin (IL)-12, IL-15, and IL-18 and of other unidentified soluble factors dependent on NK cells. Uterine NK cells comprise the largest population at implantation site, and their activity, characteristics, and abundance suggest that they participate at the "decidualization" process that, vice versa, induces NK activation and recruitment in each menstrual cycle. However, NK cell alteration may be associated with impaired pregnancy, and the modulation in the number of circulating NK cells is most likely to be a primary event rather than an active inflammation/drug administration consequence during an inflammatory/autoimmune process, thus playing an important role in the pathogenesis of immunological infertility. Relationships within immunological infertility, recurrent spontaneous abortion, autoantibodies, and NK cells will be reviewed herein.

Abstract
BACKGROUND The mechanism(s) responsible for the reduced risk of allergic disease in breastfed infants are not fully understood. Using an established murine model of asthma, we demonstrated previously that resistance to allergic airway disease transmitted from allergic mothers to breastfed offspring requires maternal B cell-derived factors. OBJECTIVE The aim of this study was to investigate the role of offspring neonatal Fc receptor for IgG uptake by intestinal epithelial cells (FcRn) in this breast milk transferred protection from allergy. METHODS Allergic airway disease was induced during pregnancy in C57BL/6 female mice. These allergic mothers foster nursed naive FcRn+/- or FcRn-/- progeny born to FcRn+/- females that were mated to C57BL/6J-FcRn-/- male mice. In offspring deficient in FcRn, we expected reduced levels of systemic allergen-specific IgG1, a consequence of decreased absorption of maternal IgG from the lumen of the neonatal gastrointestinal tract. Using this model, we were able to investigate how breast milk IgG affected offspring responses to allergic sensitization. RESULTS Levels of maternal antibodies absorbed from the breast milk of allergic foster mothers were determined in weanling FcRn-sufficient or -deficient mice. Maternal transmission of allergen-specific IgG1 to breastfed FcRn-/- offspring was at levels 103-104 lower than observed in FcRn+/- or FcRn+/+ mice. Five weeks after weaning, when offspring were 8 wk old, mice were sensitized and challenged to evaluate their susceptibility to develop allergic airway disease. Protection, indicated by reduced parameters of disease (allergen-specific IgE in serum, eosinophilic inflammation in the airways and lung) were evident in FcRn-sufficient mice nursed as neonates by allergic mothers. In contrast, FcRn-deficient mice breastfed by the same mothers acquired limited, if any, protection from development of allergen-specific IgE and associated pathology. CONCLUSIONS FcRn expression was a major factor in determining how breastfed offspring of allergic mothers acquired levels of systemic allergen-specific IgG1 sufficient to inhibit allergic sensitization in this model.

Abstract
Autism is a complex and clinically heterogeneous disorder with a spectrum of symptoms. Clinicians, schools, and service agencies worldwide have reported a dramatic increase in the number of children identified with autism. Despite expanding research, the etiology and underlying biological processes of autism remain poorly understood, and the relative contribution from genetic, epigenetic, and environmental factors remains unclear. Although autism affects primarily brain function (especially affect, social functioning, and cognition), it is unknown to what extent other organs and systems are disrupted. Published findings have identified widespread changes in the immune systems of children with autism, at both systemic and cellular levels. Brain specimens from autism subjects exhibit signs of active, ongoing inflammation, as well as alterations in gene pathways associated with immune signaling and immune function. Moreover, many genetic studies have indicated a link between autism and genes that are relevant to both the nervous system and the immune system. Alterations in these pathways can affect function in both systems. Together, these reports suggest that autism may in fact be a systemic disorder with connections to abnormal immune responses. Such immune system dysfunction may represent novel targets for treatment. A better understanding of the involvement of the immune response in autism, and of how early brain development is altered, may have important therapeutic implications.

Abstract
Systemic lupus erythematosus (SLE) is mainly a disease of fertile women and the coexistence of pregnancy is by no means a rare event. How SLE and its treatment affects pregnancy outcome is still a matter of debate. Assessment of the reciprocal clinical impact of SLE and pregnancy was investigated in a cohort study. We reviewed the clinical features, treatment, and outcomes of 43 pregnant SLE patients with 51 pregnancies followed from 1993 to 2007 at a tertiary university hospital. The age of patients was 28.7 +/- 5.4 years and SLE was diagnosed at age of 23.0 +/- 6.1 years. Previous manifestations of SLE included lupus nephritis (14 patients) and secondary antiphospholipid syndrome (11 patients). Thirty-five pregnant patients (69%) were in remission for more than 6 months at the onset of pregnancy. Patients were being treated with low doses of prednisone (29), hydroxychloroquine (20), azathioprine (five), acetylsalicylic acid (51), and low molecular weight heparin (13). Sixteen pregnancy-associated flares were documented, mainly during the second trimester (42%) and also in the following year after delivery (25%). Renal involvement was found in 11 cases (68%). Spontaneous abortion occurred in 6%, 16% had premature deliveries, and 74% were delivered at term. No cases of maternal mortality occurred. No cases of fetal malformation were recorded. There was one intrauterine fetal death and one neonatal death at 24 gestational weeks. Pregnant women with SLE are high risk patients, but we had a 90% success rate in our cohort. A control disease activity strategy to target clinical remission is essential.

Abstract
This retrospective study was designed to evaluate the outcome of pregnancies in women diagnosed with systemic lupus erythematosus (SLE) followed in a tertiary fetal-maternal center. Data were collected from clinical charts between January 1993 and December 2007, with a total of 136 pregnancies (107 patients). Mean maternal age was 29 years, with the vast majority of patients being Caucasian. Most patients were in remission 6 months prior to pregnancy (93%) and the most frequently affected organs were the skin and joints. Renal lupus accounted for 14% of all cases. Twenty-nine percent of patients were positive for at least one antiphospholid antibody (aPL) and nearly 50% had positive SSa/SSb antibodies. All patients with positive aPL received low-dosage aspirin and low-molecular-weight heparin (LMWH). There were no pregnancy complications in more than 50% of cases and hypertensive disease and intrauterine growth restriction were the most common adverse events. There were 125 live births, one neonatal death, eight miscarriages, and three medical terminations of pregnancy. Preterm delivery occurred in 25% of pregnancies. Our results are probably the conjoined result of a multidisciplinary approach together with a systematic management of SLE pregnancies, with most patients keeping their prior SLE medication combined with low-dosage aspirin and LMWH in the presence of aPL.

Abstract
OBJECTIVES The clinical relevance of antibodies anti-protein C and anti-protein S in pregnancy remains controversial. We evaluate whether, in the absence of thrombophilic diseases, maternal plasma levels of antibodies (IgM and IgG) change during pregnancy and in preeclampsia (PE), with and without superimposed fetal growth restriction (FGR). METHODS A retrospective cohort of 50 women with PE (n = 30) and PE + FGR (n = 20) and 70 controls [first trimester (n = 20); second trimester (n = 20); third trimester (n = 30)] were enrolled in the study. RESULTS In healthy pregnant women, plasma levels of anti-protein C antibodies decreased from first to third trimester and were below the range of positivity. IgM anti-protein-C and anti-protein-S were significantly higher (P < 0.001) in both PE (23.88 +/- 10.65 MoM and 43.90 +/- 20.45 MoM, respectively) and PE + FGR group (15.95 +/- 12.62 MoM and 36.02 +/- 27.43 MoM, respectively) than in control group (2.23 +/- 3.23 MoM and 1.68 +/- 4.075 MoM, respectively), in the presence of unchanged levels of IgG isotype. CONCLUSIONS In this study, we first found that the production of anti-protein C and anti-protein S antibodies decreases throughout healthy pregnancies, while they circulate in high levels in women with PE and PE/FGR.

Abstract
In neuromyelitis optica (NMO), the monoclonal B-cell antibody rituximab is a therapeutic option. Little is known about the course of NMO and the safety of rituximab during pregnancy. In this study, we report the clinical course of a patient with NMO after application of rituximab 1 week before inadvertent conception. Mother and child did not experience any adverse event, and the postpartum development of the baby was completely normal up to 15 months. Clinical course of NMO was stable during the entire pregnancy. This case illustrates a favorable outcome in a pregnant NMO patient and her child after therapy with rituximab.

Abstract
OBJECTIVES to analyse retrospectively the data of fetuses diagnosed with isolated complete atrioventricular block and efficacy of treatment of the fetus by maternal therapy. MATERIALS Between 1992 and 2004, we diagnosed complete atrioventricular block in 26 singleton and 2 twins fetuses of 27 pregnant women known to have anti Ro/La antibodies, 11 with autoimmune disease, one patient analysed in 2 pregnancies. At presentation, 20 of the fetuses were compensated and non-hydropic, while 8 had hydrops. Twenty patients were treated with dexamethasone, 2 with associated salbutamol and one mother with isoproterenol. RESULTS Age at presentation was not different between the hydropic and non-hydropic fetuses. The fetuses with hydrops, however, had a lower mean heart rate at presentation, 48.5 +/- 9.25 with a range from 32 to 60, compared to 59.95 +/- 7.9 beats per minute, with a range from 50 to 80, in the non-hydropic fetuses (p less than 0.002). Equally, after birth the mean heart rate in hydropic fetuses was 42.6 +/- 5.1, with a range from 38 to 50, as opposed to 56.05 +/- 11.8 beats per minute, with a range from 29 to 110, in the non-hydropic fetuses (p less than 0.015), The hydropic fetuses were delivered at 31.7 +/- 3.8 weeks' gestation, with a range from 29 to 38 weeks (p less than 0.003) compared to 35.5 weeks' gestation +/-2.04, with a range from 31 to 38, in the non-hydropic fetuses. Mortality was 37.5% in the hydropic fetuses, versus 5% of those without hydrops (p less than 0.02). Pacemakers were implanted in 22 of 26 infants born alive, at a median of 45 days, with a range from 1 day to 5 years, in those without hydrops during fetal life, and 3 days, with a range from 1 day to 8 months in those afflicted by hydrops, of whom 2 died despite the implant of the pacemaker. The presence and degree of hydrops had a significantly negative predictive value. No significant differences were observed between the treated and non treated cases, albeit that administration of steroids ameliorated rapidly the hydrops in 3 of 5 cases. CONCLUSIONS The outcome in our cases was mainly dependent on the presence and degree of fetal cardiac failure. Treatment of the fetus by maternal administration of steroids did not result in any regression of the conduction disorder, but had a favourable effect on fetal hydrops.

Abstract
ABSTRACT
Fetal rhythm abnormalities occur in 2% of pregnancies. They are usually identified by the obstetrician or midwifes after 20 weeks. There are four different methods used to assess fetal arrhythmias: scalp electrodes attached to electrocardiographic recordings, magnetocardiography (FMCG), fetal electrocardiographic recordings from the maternal abdomen, and fetal echocardiography (M-mode, pulsed-Doppler, Tissue-Doppler). In everyday practice the Doppler method was found to be the most useful method in the diagnosis and therapy of fetal arrhythmias. Doppler derived mechanical PR interval raised the possibility of refining the prenatal diagnosis of AV conduction abnormalities. A PR interval of >150 ms on Doppler, FMCG or postnatal ECG has been determined to be prolonged. Extrasystoles are most common cause of fetal arrhythmias, and are most often premature atrial contractions (PACs), what are usually identified in third trimester fetuses and their frequency may be highly variable. These are usually benign, resolving just before or shortly after birth. The follow-up is necessary, because some (1-3%) of affected fetuses have intermittent runs of supraventricular tachycardia. Ventricular tachycardia is rare during fetal life. With echocardiography in the setting of fetal tachycardia the findings of atrioventricular dissociation with a ventricular rate that is faster than the atrial rate suggests ventricular tachycardia. If there is 1:1 retrograde conduction it is impossible to distinguish between ventricular and supraventricular tachycardia. Atrial flutter accounted for 26.2% of all cases of fetal tachyarrhythmias and supraventricular tachycardia for 73.2%. Fouron and coworkers proposed to plan the management of the fetal tachyarrhythmia based on analysis of pulsed-Doppler recordings of fetal heart's blood flow. They determined short V-A tachycardia, when V-A (ventriculoatrial period) was shorter than AV (atrio-ventricular period) period. In the therapy of fetal supraventricular tachycardia there are different protocols, the most commonly used drugs are: digoxin, sotalol, amiodarone, flecainide. Persistent fetal sinus bradycardia is a rare condition and has been reported with central nervous system abnormalities, maternal treatment with beta blockers, excessive vagal tone, hydrops, long QT syndrome, intrauterine growth retardation and could be a sign of maternal anti-SSA/Ro antibodies. Prenatal sinus bradycardia or recognition of 2nd degree AV block may lead to early detection and treatment of long QT syndrome. Early detection of incomplete AV block, in cases of maternal anti SSA, SSB autoantibodies, successfully identifies a group at highest risk developing permanent AV block. The anti-inflammatory effects of dexamethasone might have interrupted on-going damage of the conduction system secondary to maternal autoantibodies. If the fetal arrhythmia resulted fetal hydrops, the mortality is high and the risk of late neurological morbidity must be taken into consideration. As a result of close follow-up, transplacentar treatment and well-organized perinatal management, the survival of sustained fetal arrhythmia significantly improved (50% versus 15%).

Abstract
Natural killer (NK) cells are part of the innate-immune system and respond rapidly to a variety of insults via cytokine secretion and cytolytic activity. Their main function is first line of innate immunity across viral, bacterial and parasitic infections. NK-cells are not solely killers but can also act as regulators of adaptive immunity. It is evident from literature that NK-cells are deeply involved in autoimmunity, but the question is how and why they act as a two edged weapon. Number of circulating NK-cells can be frequently altered depending on the disease taken into consideration. Cytokine milieu, the microenvironment in which they mature and other stimuli acting on different cell surface receptors may differently trigger NK-cells response and influence their role in autoimmune diseases. Functional differences between NK-cells at different anatomical sites, the adaptability of NK-cells effector responses and genetic factors may also explain differences in such responses. Thus, NK-cell alterations may be associated with increased autoimmunity and the modulation in the number of circulating NK-cells seems to be a primary event rather than an active inflammation/drug administration consequence during inflammatory/autoimmune processes, playing a fundamental role in the pathogenesis of a number of autoimmune diseases.

Abstract
OBJECTIVE To evaluate the prevalence of undiagnosed rheumatic diseases in the first trimester of pregnancy. DESIGN We screened for rheumatic diseases in 1210 consecutive pregnant women during the first trimester of pregnancy using a 10-item questionnaire. SETTING A university hospital in northern Italy. POPULATION One hundred and thirty-seven (11.3%) women who answered positively to at least one question constituted the cases and were compared with 107 negative controls. METHODS Cases and controls were tested for rheumatic autoantibodies (antinuclear antibody, anti-double-stranded DNA, anti-extractable nuclear antigen, anticardiolipin antibody, anti-beta2-glycoprotein I antibodies and lupus anticoagulant) and were evaluated by a rheumatologist for a definite diagnosis of rheumatic disease. MAIN OUTCOME MEASURES Prevalence of undiagnosed rheumatic disease in the first trimester of pregnancy. RESULTS The overall rate of positivity to the antibodies tested was 43.1% (59/137) among cases and 9.3% (10/107) in the controls (P < 0.001). A definitive diagnosis of rheumatic disease was made in 35 cases (25.5%) and in none of the controls (P <0.001). In stepwise logistic regression analysis, photosensitivity (adjusted OR 5.72; 95% CI 2.38-13.8), erythema or malar rash (adjusted OR 3.91; 95% CI 1.53-10) and history of two or more miscarriages (adjusted OR 5.6; 95% CI 1.55-20.6) were independent predictors of a definitive diagnosis of rheumatic disease (area under receiving operator curve = 0.814; 95% CI 0.76-0.86). Birthweight was lower (3180 g +/- 475 compared with 3340 g +/- 452, P= 0.008), and overall serious pregnancy complications (miscarriage, fetal growth restriction, delivery before 34 weeks of pregnancy and severe pre-eclampsia) were higher among cases (12/137) than controls (2/107) (adjusted OR 5.60; 95% CI 1.29-24.3; P= 0.021). CONCLUSIONS A two-step screening process with a self-administered questionnaire proved to be a useful method to screen for undiagnosed rheumatic diseases during the first trimester of pregnancy.

Abstract
One of the most important immunological modifications during pregnancy is the Th1/Th2 shift, due to the progressive increase of progesterone and estrogens during pregnancy, which reach their peak-level in the third trimester of gestation. At high levels, estrogens seem mainly to suppress Th1 cytokines and stimulate Th2-mediated immunological responses as well as antibody production. For this reason Th1-mediated diseases, like rheumatoid arthritis (RA), tend to improve and Th2-mediated disease, like systemic lupus erythematosus (SLE), tend to worsen during pregnancy. SLE is the autoimmune rheumatic disease in which pregnancy most frequently occurs because it predominantly affects young females in their childbearing age. Other autoimmune rheumatic diseases, including RA, are less frequently observed during pregnancy due to their low female-to-male ratio and peak onset after the age of 40. This review is focused on the disease course, gestational outcome and management of patients with SLE and RA during pregnancy.
