Abstract
Data analysis on the pathogenesis and risk factors of neonatal thrombosis was carried out. The main risk factor of any neonatal thrombosis is central catheter installment, but other maternal, fetal and neonatal factors should be taken into consideration. We discuss the epidemiology of neonatal thrombosis and the main features of the hemostasis system in newborns, the most significant risk factors, including genetic and acquired thrombophilia. We consider the von Willebrand factor activity and ADAMTS-13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) level in the development of neonatal thrombotic microangiopathy. Finally, we discuss the basic principles of prevented neonatal thrombosis by using low molecular weight heparins.

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
BACKGROUND The immune status of children exposed prenatally to immunosuppressants is not fully understood. MATERIAL AND METHODS A single-center study evaluated possible differences in antibody levels between children prenatally exposed to immunosuppressants born to mothers after hepatic or kidney transplantation (study group) compared to children without prenatal exposure to immunosuppressants (control group). Children from the study and control group were age-matched at the time of the examination and gestational age-matched, so as to obtain similar stages of the vaccination schedule and to enable reliable comparison of the results. The selection of children was made in a 1:1 ratio. The study population, a total of 138 children, was divided according to the age of the children at the time of the study into three age groups: newborns, infants (from 29 days to 1 year) and children aged >1 year. Immunoenzymatic tests were used to analyze the titers of the chickenpox virus (VZV-IgG), rubella (RuV-IgG) and hepatitis B virus (HBV, HBsAb). The studied differences were compared depending on the age group and the immunosuppressive regimen used by the pregnant mother. RESULTS In neonates born to mothers after liver transplantation, significant differences were found in HBsAb levels (>250 mIU/ml) compared to newborns without prenatal exposure to immunosuppressants taken by pregnant mothers (11/16, 69% vs. 4/14, 29%, respectively; p = .028). A similar difference in the level of HbsAb was no longer noted at later stages of children's lives. In infants, these values were 80% (4/5) vs. 33% (2/6), and in children over 1 year of age 15% (7/48) vs. 12% (6/49), respectively. No other significant differences were noted when compared the distribution of measured parameters of VZV and RuV in both analyzed groups (children of mothers after kidney or liver transplantation chronically treated with immunosuppression and children without prenatal exposure to immunosuppression). CONCLUSIONS Prenatal exposure to immunosuppressive therapy does not appear to affect VZV, RuV and HBV antibody levels in children of mothers who have had a kidney or liver transplant. Initially elevated HBSAb levels in newborns of mothers after liver transplantation are not observed in later stages of life.

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
Neonatal thromboembolism in pediatric patients is a rare but life-threatening condition mainly caused by combinations of at least 2 prothrombotic triggering risk factors such as the central venous lines, septic condition, and prematurity. Other risk factors include asphyxia, dehydration, liver dysfunction, inflammation, and maternal condition. Neonatal hemostatic system is different from one of the older children and adults. Coagulation proteins do not cross the placenta but are synthesized in the fetus from an early stage. In the term neonate, concentrations of several procoagulant proteins, particularly the vitamin K dependent and contact factors are reduced when compared with adults. Conversely, levels of antithrombin, heparin cofactor II and protein C and S are low at birth and fibrinolysis system is characterized by the decreased level of plasminogen and alpha-1-antiplasmin, increased tissue plasminogen activator. These features all tend to be gestational dependent and are more present in the preterm infant. Primarily in this context neonates appear to be at a higher risk of thrombosis than older children. Thrombotic complications reach their peak in the group of children born at 22-27 weeks. The role of inherited thrombophilic risk factors in neonatal VTE development is poorly defined. The presence of inherited and acquired thrombophilia in mother and newborn is also responsible for the development of thrombosis in neonates and should be considered. Thrombophilia in the mother can lead to increased coagulation potential and prethrombotic conditions during pregnancy, causing thrombotic vasculopathy at the placental level. The benefit of identifying thrombophilia in the sick preterm newborns who are in the group of risk for development of thrombotic complications may facilitate the thromboprophylaxis. Further research regarding assessment of risk factors, diagnostics and treatment strategy is required.

Abstract
Eosinophilic gastroenteritis (EGE) is an uncommon and heterogeneous disease characterized by eosinophilic infiltration of the gastrointestinal tract. There are very few reports in literature describing pregnancies in EGE patients, and no review has ever been published. We found a total of 12 cases including one that occurred in our clinic. In 5 out of 12 cases, EGE was diagnosed after delivery and pregnancies are described as uneventful. Of the 5 patients who already had a diagnosis of EGE before pregnancy, only one registered an improvement of symptoms during gestation, while the rest had no significant changes, and their pregnancies needed to be monitored as high risk. Regarding pregnancy complications, only two patients had a pre-term delivery. Both patients had not only EGE, but a remarkable obstetrical history, that could slightly complicate the interpretation of the events that occurred in their pregnancies. More studies are necessary to demonstrate if EGE is connected with pre-term onset of labor. It's not easy to define the reasons of some patient's pre term labor, and we could suppose that a combination of different mechanisms leads to this condition of breakdown of maternal-fetal tolerance. Nevertheless, we know that spontaneous preterm labor is a syndrome attributable to multiple pathologic processes and most of them are yet to be understood. However, we cannot exclude that EGE is related to late preterm delivery. We hope that this review will provide some measures of guidance to those clinicians who must satisfy the questions of young female patients diagnosed with EGE and wishing for a pregnancy.

Abstract
Antiphospholipid syndrome (APS) is a rare condition in childhood, but even more in the neonatal age. Most neonatal cases are considered a passively acquired autoimmune disease, due to a transplacental passage of maternal antiphospholipid antibodies (aPL) from mothers with primary or secondary APS or, more often, from asymptomatic aPL carriers. Exceedingly unusual is the neonatal de novo production of aPL. We present four infants with presumed perinatal stroke in presence of increased and persistent aPL levels, even after 6 months of life, opening the window on a gray zone related to the origin of these antibodies (maternal or neonatal) and on their role in the pathogenesis of stroke.

Abstract
Most infants born to mothers with autoimmune diseases are thought to be entirely healthy. However, the immunological conditions have not been examined thoroughly. Fourteen neonates born to mothers with systemic autoimmune diseases, namely systemic lupus erythematosus, mixed connective tissue disease, Sjögren's syndrome, rheumatoid arthritis, and systemic sclerosis, were included. Serum concentrations of 17 cytokines from the infants' umbilical artery (UA) and vein (UV) and from the mothers' peripheral blood were investigated by a bead array system. Cytokine expression in the placenta was investigated by immunohistochemical staining. The disease was controlled in all mothers, and none had chorioamnionitis. Hypercytokinemia was found in 11 neonates irrespective of their mothers' autoimmune diseases. In six neonates, serum cytokines were at extremely high levels. Four neonates were born by cesarean section because of a non-reassuring fetal status (NRFS) of unknown cause were all included in the hypercytokinemia group. However, all the subjects were discharged without any complications. The cytokine levels were almost the same between UA and UV, but the mothers' blood samples did not show elevation of serum cytokines. There were no differences in the expression of cytokines in the placenta among three patients with different serum cytokines levels. Hypercytokinemia frequently occurred and a cytokine storm state sometimes developed in neonates born to mothers with systemic autoimmune diseases. Growth restriction and NRFS may be related to hypercytokinemia in utero. It is plausible that the high level of cytokines in cord blood originate in neither the mother nor the placenta but in fetal immune tissues. It is important to investigate the immunological mechanisms, prevalence, and long-term influence of hypercytokinemia in a large sample size of neonates and mothers with systemic autoimmune diseases.

Abstract
BACKGROUND Pregnancy after kidney transplantation has been considered as high risk for maternal and fetal complications. After careful patient selection successful pregnancies are described. Little is known about fetal outcomes and data is particularly scarce on childrens´ early development up to two years when born to kidney/-pancreas transplant recipients. Here, we analyzed maternal and fetal risk and evaluated graft function during pregnancy in transplanted women. We aimed to identify factors affecting the outcomes of mothers and their grafts during pregnancy and of children up to 2 years after delivery/ birth. METHODS All consecutive pregnancies in kidney/ kidney-pancreas recipients with live-born children from 2002 to 2016 were evaluated in two transplant centers (Charité Berlin/ University Tuebingen). All data was gathered from medical records. Impact of pregnancy on obstetrical risks, graft function and fetal development was evaluated. Additionally, for the first time development of children, including physical examination and assessment of neurological function were evaluated at 12 and 24 months. RESULTS Thirty-two pregnancies in 28 patients with a median duration of 34 gestational weeks (range, 24-38) were analyzed. 13 patients (46.4%) developed deterioration of kidney graft function > 10 ml/min during pregnancy. In majority, caesarean section was performed (75%). Twenty-five (78.1%) children were born prematurely, thereof (16%) < 28 weeks. Almost 70% had low birth weights (LBW) (< 2.500 g); median birth weight was 2.030 g. General health and physical constitution of children were unremarkable with normal development in 94% at 12 and 24 months of corrected age, respectively. CONCLUSION Despite the high rate of preterm birth and LBW, development up to two years was age-appropriate in this cohort. Due to low absolute numbers, increasing efforts in centralized counseling, diagnostics and committed specialist support are required. Decisive treatment of these high-risk patients in specialized units leading to better performance of these patients (mother/ fetus) is deemed superior. In order to confirm this, prospective studies on neonatal and pediatric outcomes with a standard-of-care comparator arm will be conducted.

Predicting the Risk of Macrosomia at Mid-Pregnancy Among Non-Diabetics: A Retrospective Cohort Study. JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2017; 39:1129-1136. [PMID: 28780218 DOI: 10.1016/j.jogc.2017.05.032] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2017] [Revised: 05/28/2017] [Accepted: 05/29/2017] [Indexed: 01/26/2023]
Abstract
OBJECTIVE To identify factors known in mid-pregnancy to be associated with risk of macrosomia (≥4000 g) among non-diabetic women and to develop a risk score to allow early identification of women at high risk. METHODS Data were obtained from a population-based perinatal database and a hospital laboratory database in Nova Scotia, Canada. The study included singleton live births born to non-diabetic women between 1998 and 2005. Logistic regression was used to identify risk factors significantly associated with macrosomia. Risk scoring systems were developed for nulliparous and parous women separately and validated using the C-statistic. RESULTS Of the 23 857 mother-infant pairs included in the study, 16.7% of the infants were macrosomic. In nulliparous women, seven risk factors were identified, of which pre-pregnancy weight ≥90 kg with an OR of 4.8 (95% CI: 3.9 to 6.0) contributed a greater number of points to the risk score. The resulting risk score corresponded to a range of estimated risk of 0.2% to 47.0% and had a C-statistic of 0.70. In parous women, the most points were assigned to women with a previous large birth (OR: 3.7; 95% CI: 3.2-4.0) and a pre-pregnancy weight ≥90 kg (OR: 3.8; 95% CI: 3.1-4.7). The resulting risk score corresponded to a range of estimated risk of 0.4% to 88.0% and had a C-statistic of 0.75. CONCLUSIONS Macrosomia risk can be estimated by a simple calculation based on a woman's risk factor profile at mid-pregnancy.

Risk of infections during the first year of life after in utero exposure to drugs acting on immunity: A population-based cohort study. Pharmacol Res 2016; 113:557-562.

Abstract
The aim of the study was to evaluate the association between in utero exposure to drugs that potentially exhibit immunosuppressive activity and occurrence of infections during the first year of life. We conducted a cohort study on the prescription data of pregnant women and their children registered in EFEMERIS cohort (France), during a one-year period. We classified in utero child exposure according to the number of reimbursements for immunosuppressive drugs during pregnancy. The number of infectious episodes during the first year of life was estimated through the number of anti-infective drugs dispensed. The association was estimated by a quasi-Poisson regression with adjustment for confounders. The study population consisted of 9614 children, 3141 of whom had been exposed to immunosuppressive drugs during pregnancy. The most frequently immunosuppressive drugs prescribed were corticosteroids. The mean number of infectious episodes during the first year after birth gradually increased with the number of immunosuppressive drugs dispensed during pregnancy (from 2.38 in controls to 3.88 in the most exposed group). After adjustment for potential confounders, in utero exposure to immunosuppressive drugs was significantly associated with the number of infectious episodes during the first year of life (RR 3ormoreexposuresVS0=1.35, 95% CI 1.24-1.46). Intrauterine exposure to potentially immunosuppressive drugs could be associated with an increased susceptibility to infections in early childhood.

Abstract
Overexposure to prenatal glucocorticoid (GC) disturbs hypothalamic-pituitary-adrenocortical axis-associated neuroendocrine metabolism and susceptibility to metabolic syndrome. A high-fat (HF) diet is a major environmental factor that can cause metabolic syndrome. We aimed to investigate whether prenatal GC plus a postnatal HF diet could alter immune programming in rat offspring. Pregnant Sprague-Dawley rats were given intraperitoneal injections of dexamethasone or saline at 14-21 days of gestation. Male offspring were then divided into four groups: vehicle, prenatal dexamethasone exposure, postnatal HF diet (VHF), and prenatal dexamethasone exposure plus a postnatal HF diet (DHF). The rats were sacrificed and adaptive immune function was evaluated. Compared to the vehicle, the DHF group had lower interferon gamma (IFN-γ) production by splenocytes at postnatal day 120. Decreases in H3K9 acetylation and H3K36me3 levels at the IFN-γ promoter correlated with decreased IFN-γ production. The impaired IFN-γ production and aberrant site-specific histone modification at the IFN-γ promoter by prenatal dexamethasone treatment plus a postnatal HF diet resulted in resilience at postnatal day 180. Prenatal dexamethasone and a postnatal HF diet decreased IFN-γ production through a site-specific and an age-dependent histone modification. These findings suggest a mechanism by which prenatal exposure to GC and a postnatal environment exert effects on fetal immunity programming.

Abstract
Neonatal antiphospholipid syndrome (neonatal APS) seems to be exceedingly rare, as the antiphospholipid antibodies (aPL) related thrombosis in the neonatal period. The pathogenesis of perinatal aPL related thrombosis may be explained both by the transplacental passage of the maternal antibodies and by the production of de novo antibodies by the neonate. However, few cases of neonatal APS are reported in the literature, especially regarding arterial thrombotic events. In particular, only two cases of neonatal aPL related isolated cerebral sinovenous thrombosis (CSVT) are described in the literature. Despite its frequency, CSVT results in significant mortality and morbidity, probably also due to the difficulty in early diagnosis and then in correct managing in the neonatal period. A diagnosis of neonatal APS should be considered in the evaluation of neonates with CSVT, as well as in any case of neonatal thrombosis, to correctly manage the affected neonates and counsel the mother for future pregnancies.

Abstract
The peripartum period entails the next prenatal interval when novel neuroprotective strategies will be designed and tested. Research development will lead to novel evaluations for maternal-fetal pairs who require inpatient treatment and possible delivery for worsening or acute neurologic problems. Future studies should critically compare serial fetal surveillance assessments with postnatal clinical findings to detect and treat more accurately fetal/neonatal brain disorders that begin or worsen during the peripartum period. Clinical management decisions require an interdisciplinary treatment approach. Protocols may begin before and during parturition, and continue through neonatal resuscitation and early postnatal periods into infancy. Appropriate choices of preventive, rescue, and repair neuroprotective interventions must consider both the timing and etiologies of encephalopathies in the context of maternal, fetal, placental, and neonatal diseases.

Abstract
In human newborns, endogenous levels of plasma immunoglobulin G (IgG) begin to rise slowly after birth following exposure to the environment. For immunoprotection during fetal and early neonatal life, maternal IgG is provided by transplacental transport. While cellular immunoprotective IgG effects are mainly triggered by FcγRI, -RII and -RIII, transplacental IgG transfer is mediated by the MHC class I-like neonatal Fc-receptor, hFcRn. This compact review explains the mechanism of hFcRn-mediated IgG transcytosis across the placental barrier - syncytiotrophoblast and fetal endothelial cells. Restrictions of this IgG transport are summarized. These include IgG subclass discrimination and limited IgG transport before the third trimester that can cause insufficient protection from infections of preterm (≤ 35 th week) delivered babies. As hFcRn does not discriminate beneficial from hazardous IgGs, maternal auto- and alloimmune as well as therapeutic antibodies can reach the fetus. The consequences including severe diseases of the newborn are summarized in this article.

Abstract
'Neonatal' lupus erythematosus (NLE) describes a clinical spectrum of cardiac and non-cardiac abnormalities observed in neonates and foetuses whose mothers have the auto-antibodies anti-SSA/Ro (anti-Ro) and anti-SSB/La (anti-La). Of the cardiac abnormalities, congenital AVB is the most common cardiovascular abnormality found in affected foetuses and infants. Many other cardiovascular manifestations of NLE have been more recently recognized including atrial and ventricular arrhythmias and other conduction abnormalities, myocarditis, cardiomyopathy often with endocardiofibroelastosis and structural heart disease, particularly valvar lesions. In this report, the spectrum of cardiovascular manifestations observed in foetuses and infants with NLE are reviewed and the pathogenesis, diagnosis and clinical outcomes are briefly discussed.
