Abstract
INTRODUCTION Neonatal lupus erythematosus (NLE) is a rare autoimmune disease, which needs to be distinguished from eczema, congenital syphilis, and tinea corporis in newborns. Reflectance confocal microscopy (RCM) could be a helpful noninvasive diagnostic tool, which has been used to evaluate several inflammatory skin conditions. The aim of this study was to describe the RCM characteristics of NLE. METHODS Eleven NLE patients were included in the study, and all patients were evaluated clinically with RCM. We also evaluated RCM images from 11 eczema patients as controls. RESULTS Some major key diagnostic features of NLE can be observed by RCM: an enlarged honeycomb pattern (9/11, 81.8%), round-to-oval cyst-like structures were present (6/11, 54.5%), the normal ring-like structures were totally or partially obliterated (11/11, 100%) at the level of the dermo-epidermal junction, medium refractivity collagen fibers that were disorganized (10/11, 90.9%), numerous high refractivity round cells (11/11, 100%) in the dermis. CONCLUSION RCM allows the visualization of major key diagnostic features of NLE and serves as a complementary diagnostic tool for NLE.

Abstract
Neonatal lupus erythematosus (NLE) is caused by the transmission of maternal anti-Ro/SSA antibodies, anti-La/SSB antibodies, and other autoantibodies to the fetus through the placenta. Usually, with the disappearance of autoantibodies in the children's body, abnormal changes in the mucocutaneous, blood system, and digestive system can spontaneously subside, but the damage to various systems caused by autoantibodies may persist for a long time. This article provides a comprehensive review of the manifestations and prognosis of NLE in various systems, including mucocutaneous, blood system, circulatory system, nervous system, digestive system, respiratory system, aiming to provide reference for clinical work.

Abstract
This study aims to analyze the clinical characteristics and risk factors of high-risk groups of neonatal lupus erythematosus (NLE) in term infants. High-risk groups of NLE infants whose mothers were positive for anti-SSA, anti-SSB or anti-U1RNP antibodies during pregnancy were enrolled. They were born between February 2013 and February 2020, with a gestational age not less than 37 weeks. We analyzed their clinical data from birth to 24 months after birth. A total of 105 patients in the NLE high-risk group were included. Among them, 30 patients were diagnosed with NLE (NLE group), and 75 patients were not (non-NLE group). The affected systems of the NLE group included the dermal (13.3%), hepatic (76.0%), and hematological systems (43.3%). Hepatic involvement, anemia and thrombocytopenia did not emerge until 60 days, 41 days and 22 days after birth, respectively, in some cases. Systemic involvement could be cured within 3 to 12 months after birth. The clearance time of specific autoantibodies was 12 months after birth. There was no significant difference in the clinical characteristics of babies and their mothers between the two groups, neither in the positive rate nor in the clearance time of specific autoantibodies. CONCLUSION After standardized prenatal health care, there is still a high risk of dermal, hepatic, or hematological system involvement for high-risk groups of NLE. There are no specific indicators for the prediction of whether babies will develop NLE. All of these patients need to be followed up closely within one year after birth. WHAT IS KNOWN • Neonatal lupus erythematosus (NLEs) can affect the cardiac, dermal, hepatic, and hematological systems of infants. WHAT IS NEW • After standardized prenatal health care employing good multidepartment cooperation in our center, no neonates had cardiac block in this study. However, dermal, hepatic, and hematological system involvement of NLE can still gradually appear (as long as 60 days after birth in some cases) during follow-up, and some of these conditions are serious and require timely and active intervention. No single factor has been found to predict whether offspring at high-risk of NLE whose mothers are positive for anti-SSA, SSB and/or RNP will develop NLE.

Abstract
BACKGROUND Neonatal lupus erythematosus is a rare multisystem autoimmune disorder that predominantly involves the heart with congenital heart block but can involve other organs including the liver. The disease results from passage of maternal autoantibodies to the fetus and manifests in various forms depending on the organ involved. Neonatal lupus liver disease manifestations range from benign elevation in aminotransferases to fatal hepatic insufficiency with iron deposition that does not respond to therapy. Only a handful of cases have been reported to date. The antibodies implicated are Sjogren Syndrome types A and B antibodies. Other non-specific autoantibodies can be positive as well such as antinuclear antibodies. Smooth muscle antibodies are classically considered specific to autoimmune hepatitis, and while they have been described in other chronic liver diseases, they have not been described in neonatal lupus liver disease. Herein we report a rare case of neonatal cholestasis due to neonatal lupus liver disease that presented with a positive smooth muscle antibodies in addition to a biochemical picture of neonatal hemochromatosis, with a remarkably elevated ferritin, that responded well to steroid therapy. CASE PRESENTATION An 8-day old full-term baby girl was referred to our center for evaluation of neonatal bradycardia and generalized jaundice that started in the first day of life. Prenatal history was significant for fetal bradycardia. Examination was unremarkable except for bradycardia and generalized jaundice. Laboratory findings included elevated alanine aminotransferase, aspartate aminotransferase, Alkaline Phosphatase, and total and direct bilirubin. Her ferritin was markedly elevated along with triglycerides. Sjogren syndrome antibodies were positive in addition to antinuclear and anti-smooth muscle antibodies. The diagnosis of cardiac neonatal lupus was given, and her liver disease was attributed to lupus despite the biochemical picture of neonatal hemochromatosis. She was started on oral prednisolone for which her liver function parameters showed a dramatic response and continued to be within the normal limits several weeks after discontinuation of steroids. CONCLUSION Neonatal lupus liver disease is a rare cause of neonatal cholestasis that can rarely present with neonatal hemochromatosis picture which unlike other causes of neonatal hemochromatosis can be reversed with steroid therapy.

Abstract
OBJECTIVES To identify the prenatal predisposing factors related to neonatal lupus erythematosus (NLE). MATERIALS AND METHODS A retrospective case-control study was made of 131 pregnant women with positive anti-Ro or anti-La autoantibodies and known neonatal outcomes between January 2002 and December 2019 at Siriraj Hospital, Bangkok, Thailand. There were 101 unaffected neonates and 30 NLE cases confirmed postnatally. Demographic and clinical data of the mothers and neonates with and without NLE were statistically compared. RESULTS NLE was diagnosed in 30 out of 131 cases. A multivariate analysis identified the following significant factors for NLE: maternal anti-La antibodies (odds ratio (OR), 3.591; p = 0.030); and maternal treatment with either hydroxychloroquine (OR, 0.082; p = 0.001) or prednisolone (OR, 0.136; p = 0.017). Of the significant variables examined in the multivariate analysis models, high levels of maternal anti-La antibodies were found to be the strongest predictor of noncardiac NLE (OR, 4.558; p = 0.032), while a female baby was significantly higher in pregnancies complicated by cardiac NLE (OR, 5.374; p = 0.046). Hydroxychloroquine still provided a protective effect for both cardiac and noncardiac NLE (p = 0.039 and 0.032, respectively). CONCLUSIONS The maternal anti-La antibodies were a beneficial predictor for NLE, especially as their high titers were influentially associated with noncardiac features. A female fetus seemed to present an increased risk for developing a congenital heart block. Nevertheless, the treatment with hydroxychloroquine during the pregnancies demonstrated a potentially protective factor against both cardiac and noncardiac manifestations.

Abstract
BACKGROUND Macrophage activation syndrome (MAS) is a life-threatening hyperinflammatory syndrome and is caused by a severely dysregulated immune response. It has rarely been associated with neonatal lupus. CASE PRESENTATION We present a female neonate with MAS born to a mother who had cutaneous lupus erythematosus with circulating anti-nuclear antibodies (ANA), anti-SSA, anti-SSB and anti-extractable nuclear antigen (anti-ENA) antibodies. Because of neonatal lupus (NLE) with a total atrioventricular block, epicardial pacemaker implantation was required on the sixth day of life. Following surgery she developed non-remitting fever and disseminated erythematous skin lesions. A diagnosis of MAS was made based on these symptoms, with hyperferritinemia, elevated transaminases, hypertriglyceridemia, and a skin biopsy that showed hemophagocytosis. Our patient was treated with steroids for 3 months with good effect. No relapse has occurred. CONCLUSIONS MAS is a rare complication of neonatal lupus that may be difficult to diagnose, but needs to be treated promptly. In this article, pathogenesis and overlap of MAS and hemophagocytic lymphohistiocytosis (HLH) has been described. Diagnosis of MAS can be difficult. Different diagnostic criteria are used in both diagnosing MAS and HLH. Validated criteria for diagnosis of MAS in other disease than systemic onset JIA have not been validated yet. In NLE, diagnosing MAS is even more difficult, since skin lesions are already common in NLE. We show the potential additional value of skin biopsy in diagnosing MAS.

Abstract
A 31-day-old infant was admitted to the pediatric intensive care unit due to shock and anemia. The mother had systemic lupus erythematosus and direct antiglobulin test (DAT)-positive hemolytic anemia. The perinatal course of this infant and the mother was uneventful. Regular health check screenings revealed that activity, growth, and development were unremarkable at birth, 5, and 28 days of life. Passive immune hemolytic anemia due to neonatal lupus erythematosus was diagnosed based on a positive DAT for warm-type IgG antibodies, reticulocytosis, and lupus-specific antibodies at rehospitalization. It was complicated by cytomegalovirus (CMV) antigenemia. Umbilical cord blood and peripheral blood samples obtained from the infant at 5 days after birth were negative for CMV DNA. The infant was curatively treated by intensive care with repeated blood transfusions and antiviral therapy. This is the first report indicating that CMV infection exacerbates hemolytic anemia in patients with maternal red blood cell alloantibodies.

Abstract
Neonatal lupus (NL), a passively-acquired autoimmune disease associated with maternal anti-SSA antibody, presents both cardiac manifestations such as cardiac NL and non-cardiac manifestations including rashes, cytopenia, and hepatic abnormalities. Cardiac NL, occurring in 1-2% of anti-SS-A antibody-positive mothers, is a life-threatening complication with a mortality rate of 20% and a pacemaker implantation rate of 70%. In contrast, cutaneous NL, which is more common than cardiac NL, usually resolves in six months. Since half of NL cases occur in asymptomatic mothers, if an infant presents characteristic cutaneous or cardiac manifestations of NL, the mother should be tested for anti-SS-A antibody. In mothers positive for anti-SS-A antibody, the risk of having a child with cardiac NL increases ten-fold and five-fold for a previous child with cardiac NL and cutaneous NL, respectively. A joint American, British, and French retrospective study of NL registries showed that hydroxychloroquine (HCQ) reduced the cardiac NL risk in subsequent pregnancies in mothers who previously had a child with cardiac NL. A prospective open-label study to confirm this effect is being undertaken in the USA. A similar prospective multi-center study will be undertaken in Japan. Establishing a Japanese registry of children with NL and subsequent pregnancies of their mothers will help promote clinical research in NL in Japan.

Abstract
We report a rare case of isolated thrombocytopenia related to anti-Ro/SSA antibodies. The mother was followed for unlabeled familial thrombocytopenia. The mother had positive anti-Ro/SSA antibodies. She was asymptomatic without skin lesions or other criteria neither of systemic lupus erythematosus nor other connective tissue disease. Pregnancy was uneventful. The postnatal examination was normal. On the first day of life, blood cells count showed thrombocytopenia at 40 x 109/L. Within the second day of life, platelet level dropped to 20 x 109/L. The management of thrombocytopenia included platelet transfusion and human immunoglobulin infusion. On the fifth day of life, there has been a drop in platelet count to 10 x 109/L requiring renewed platelet transfusion and human immunoglobulin infusion. On the 10th of life platelets rate was stable around 60 x 109/L. The infant had no evidence of cardiac, dermatologic or hepatobilary involvement initially or throughout follow up.

Abstract
The aims of our study are to observe the pregnancy outcome of anti-Sjögren's syndrome-related antigen A (SSA)/Ro-positive women and to predict the risk factors for adverse pregnancy outcome and neonatal lupus erythematosus (NLE). Clinical data of 126 anti-SSA/Ro-positive patients with 140 pregnancies were evaluated retrospectively, and the newborns were followed up as a cohort in 3 months. χ (2) test or logistic regression was used to predict the risk factors of lupus flares during pregnancy, fetal loss, and NLE. Twenty-six out of 93 pregnancies with systemic lupus erythematosus (SLE) experienced flares during pregnancy. Active disease prior to conception was the independent risk factor for flares [P = 0.002, odds ratio (OR) = 10.41 (95 % confidence interval (CI) = 2.34∼46.26)]. Continuous use of steroids and hydroxychloroquine (HCQ) might help decrease the risk (P = 0.041 and 0.015, respectively). Eleven out of 140 pregnancies ended with fetal loss, and 9 out of 113 live births were diagnosed with NLE. The presence of anti-phospholipid syndrome (APS) was associated with fetal loss (P = 0.018, OR = 6.41 (95 % CI = 1.57-26.14)). The presence of anti-Sjögren's syndrome-related antigen B (SSB)/La antibodies tended to increase the risk of giving birth to an infant with NLE (P = 0.140); on the other hand, duration of disease, history of renal involvement, and active SLE during pregnancy did not contribute to the incidence of NLE (P = 0.649, 0.685, and 1.000, respectively). Active disease without regular follow-up before conception significantly increased the risk of lupus flares during pregnancy. The continuous use of low-dose steroids and hydroxychloroquine might help maintain lower SLE activity. Concurrent APS instead of high titer of anti-SSA/Ro might raise the risk of fetal loss in anti-SSA/Ro-positive patients.

Abstract
Neonatal lupus syndrome is associated with transplacental passage of maternal anti-SSA/Ro and anti-SSB/La antibodies. Children display cutaneous, hematological, liver or cardiac features. Cardiac manifestations include congenital heart block (CHB); endocardial fibroelastosis and dilated cardiomyopathy. The prevalence of CHB in newborns of anti-Ro/SSA positive women with known connective tissue disease is between 1 and 2% and the risk of recurrence is around 19%. Skin and systemic lesions are transient, whereas CHB is definitive and associated with significant morbidity and a mortality of 18%. A pacemaker must be implanted in 2/3 of cases. Myocarditis may be associated or appear secondly. Mothers of children with CHB are usually asymptomatic or display Sjogren's syndrome or undifferentiated connective tissue disease. In anti-Ro/SSA positive pregnant women, fetal echocardiography should be performed at least every 2 weeks from the 16th to 24th week gestation. An electrocardiogram should be performed for all newborn babies. The benefit of fluorinated corticosteroid therapy for CHB detected in utero remains unclear. Maternal use of hydroxychloroquine may be associated with a decreased recurrent CHB risk in a subsequent offspring. A prospective study is actually ongoing to confirm these findings.

AIM To investigate the correlation between maternal autoantibodies and age at diagnosis of isolated complete atrioventricular (AV) block (CAVB) and to study signs of late progression of foetal immune-mediated insults in cases of postnatally diagnosed CAVB. METHODS Patients with CAVB (n = 190) identified in a population-based manner were included. Maternal autoantibody profile was correlated with age at CAVB diagnosis. A structured review of medical records was performed if a late CAVB diagnosis (>27 days post-partum) was associated with a sero-positive mother. RESULTS Maternal Ro/La autoantibodies were observed in 88% of cases with a congenital diagnosis. Thirteen cases with a sero-positive mother and late CAVB diagnosis were found (age-range: 4 months-43 years). In two cases, CAVB was diagnosed in conjunction with infections, one case had a family history of cardiomyopathy and two cases had nontypical clinical presentations, indicating alternative pathogenetic mechanisms. In the remaining eight cases, no likely factors inducing CAVB, other than maternal autoantibodies, could be identified. CONCLUSION Our observations support the hypothesis that late progression to CAVB can be the result of an immune-mediated pathogenetic mechanism during foetal life. An autoantibody-associated diagnosis after the neonatal period is therefore possible, and testing of maternal serology at the time of diagnosis is recommended.

Abstract
Autoantibody-associated congenital heart block (CHB) is a passively acquired autoimmune condition associated with maternal anti-Ro/SSA antibodies and primarily affecting electric signal conduction at the atrioventricular node in the fetal heart. CHB occurs in 1-2% of anti-Ro/SSA antibody-positive pregancies and has a recurrence rate of 12-20% in a subsequent pregnancy. Despite the long-recognized association between maternal anti-Ro/SSA autoantibodies and CHB, the molecular mechanisms underlying CHB pathogenesis are not fully understood, but several targets for the maternal autoantibodies in the fetal heart have been suggested. Recent studies also indicate that fetal susceptibility genes determine whether an autoantibody-exposed fetus will develop CHB or not, and begin to identify such genes. In this article, we review the different lines of investigation undertaken to elucidate the molecular pathways involved in CHB development and reflect on the hypotheses put forward to explain CHB pathogenesis as well as on the questions left unanswered and that should guide future studies.

Abstract
Systemic lupus erythematosus (SLE) typically affects women in their childbearing age, who have the same fertility rates as the healthy population. The effect of pregnancy on the disease and the effect of SLE on pregnancy and the fetus are highly important issues for the attending physician. Whether lupus flares are more frequent during pregnancy remains controversial. Among the possible effects of SLE on pregnancy are a greater number of abortions, fetal loss, pre-term deliveries and perinatal mortality. The newborn may be affected by the onset of neonatal lupus erythematosus (neonatal LE), either as a skin or blood disease, or by the presence of congenital heart block. The frequent association between SLE and antiphospholipid syndrome represents another risk situation for the mother and the product of conception. Multiples drugs used in SLE patients should be evaluated. Those with teratogenic potential should be withdrawn before pregnancy, and when necessary, appropriate medications should be indicated to treat the mother without compromising the safety of the baby. In conclusion, pregnancies in lupus patients represent a challenge for the physician and must be closely followed up and treated if necessary, during all trimesters and in the puerperium period, to improve outcome.

Abstract
Neonatal lupus erythematosus (NLE) is an autoimmune disease that is associated with transplacental passage of maternal autoantibodies that are reactive to SSA/Ro and SSB/La antigens. Cardiac involvement, hematologic abnormality and hepatic disease may occur in the infants suffering with NLE, in addition to the characteristic skin lesions. We report here on a case of NLE in a 4-week-old female infant who was born to an asymptomatic mother, and the baby displayed the characteristic clinical and histological features of cutaneous NLE with transient anemia and hepatitis. Both the infant and mother were positive for anti-SSA/Ro and anti-SSB/La. There have been 18 case reports of NLE in the Korean literature, including 7 case reports in the dermatological field. We describe herein another case of NLE that showed transient anemia and hepatitis, and we also review the case reports of NLE in the Korean literature.
