This study, conducted by searching keywords such as \"maternal lupus\", \"neonatal lupus\", and \"congenital heart block\" in databases including PubMed and Scopus, provides a detailed narrative review on fetal and neonatal lupus. Autoantibodies like anti-Ro/SSA and anti-La/SSB may cross the placenta and cause complications in neonates, such as congenital heart block (CHB). Management options involve hydroxychloroquine, which is able to counteract some of the adverse events, although the drug needs to be used carefully because of its impact on the QTc interval. Advanced pacing strategies for neonates with CHB, especially in severe forms like hydrops, are also assessed. This review emphasizes the need for interdisciplinary care by rheumatologists, obstetricians, and pediatricians in order to achieve the best maternal and neonatal health in lupus pregnancies. This multidisciplinary approach seeks to improve the outcomes and management of the disease, decreasing the burden on mothers and their infants.

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.
新生儿红斑狼疮（neonatal lupus erythematosus, NLE）是由母体的抗-Ro/SSA抗体、抗-La/SSB抗体等自身抗体通过胎盘传给胎儿所致，通常随着患儿体内自身抗体的消失，皮肤黏膜、血液及消化系统等的异常改变可自行消退，但由于自身抗体所导致的各系统损害可能长期存留。该文综述了NLE在皮肤黏膜、血液系统、循环系统、神经系统、消化系统、呼吸系统等方面的表现及预后的研究进展，以期为临床工作提供参考。.

BACKGROUND: 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.
CONCLUSIONS: RCM allows the visualization of major key diagnostic features of NLE and serves as a complementary diagnostic tool for NLE.

UNASSIGNED: Systemic lupus erythematosus (SLE), a common autoimmune disease predominantly affecting women, has been linked to various complications during pregnancy. The transfer of anti-Ro/SSA antibodies from SLE-affected mothers to their offspring can lead to neonatal lupus and cardiac issues. This study investigated the association between maternal SLE and the risk of pediatric cardiovascular disorders.
UNASSIGNED: The study utilized South Korea\'s National Health Insurance Service (NHIS) database, covering 3,505,737 children born between 2007 and 2017 and tracked until 2020. Maternal SLE cases were identified using the World Health Organization\'s International Classification of Diseases Tenth revision (ICD-10) codes and linked with delivery records. Cardiologic disorders were categorized into congenital heart disease (CHD), arrhythmic disorders, and acquired heart disease. Propensity score matching with 1:4 ratios was applied to the set control group.
UNASSIGNED: Among 3,505,737 children, 0.7% (n = 23,330) were born to mothers with SLE. The incidence of preterm birth was significantly higher in the maternal SLE group (5.9% vs. 3.0%). Compared with the control group, children born to mothers with SLE exhibited a significantly elevated risk of overall CHDs (5.5%, adjusted odds ratio [aOR] 1.21; 95% confidence interval [CI] 1.14-1.29), including atrial septal defect (1.18; 1.09-1.28) and patent ductus arteriosus (1.15; 1.03-1.30). In addition, a notably higher risk was observed in arrhythmic disorders (complete atrioventricular block 7.20; 2.41-21.49) and acquired cardiac disorders, including cardiomyopathy (1.40; 1.17-1.68) and mucocutaneous lymph node syndrome (MCLS) (1.27; 1.15-1.43).
UNASSIGNED: Maternal SLE is associated with congenital and acquired cardiac disorders in offspring, including structural, arrhythmic, and MCLS. This study highlights the need for continuous cardiovascular monitoring from the prenatal stage to preadolescence in these children due to multifactorial influences involving maternal autoantibodies, genetic predisposition, and environmental factors.

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.
CONCLUSIONS: 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.
BACKGROUND: • Neonatal lupus erythematosus (NLEs) can affect the cardiac, dermal, hepatic, and hematological systems of infants.
BACKGROUND: • 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.

Neonatal lupus erythematosus (NLE) is an autoimmune disease caused by the passive transfer of autoantibodies from mother to child during pregnancy. A rare complication of NLE is hemophagocytic lymphohistiocytosis (HLH), a potentially life-threatening hyperinflammatory state more commonly associated with other rheumatologic disorders. Herein, we describe a fatal case of NLE-associated HLH.

Neonatal lupus erythematosus (NLE) is an uncommon disorder affecting approximately one out of 20 000 live births in the United States. Common manifestations of NLE include cutaneous eruptions and cardiac involvement. The typical rash of NLE most closely resembles the rash of subacute cutaneous lupus erythematosus both clinically and histopathologically. We present a case of reactive granulomatous dermatitis (RGD) associated with NLE in a 3-month-old male in whom the initial histopathology and immunohistochemistry were concerning for hematologic malignancy. RGD is a unifying term used to describe cutaneous granulomatous eruptions that occur in response to a variety of stimuli, including autoimmune connective tissue diseases. Our case demonstrates the range of histopathological findings that may be present in the setting of NLE.

We report three unrelated individuals, each exposed to maternal autoantibodies during gestation and found to have elevated very long-chain fatty acids (VLCFAs) in the newborn period after screening positive by California newborn screening (NBS) for X-linked adrenoleukodystrophy (ALD). Two probands presented with clinical and laboratory features of neonatal lupus erythematosus (NLE); the third had features suggestive of NLE and a known maternal history of Sjogren\'s syndrome and rheumatoid arthritis. In all three individuals, subsequent biochemical and molecular evaluation for primary and secondary peroxisomal disorders was nondiagnostic with normalization of VLCFAs by 15 months of age. These cases add to the expanding differential diagnosis to consider in newborns who screen positive for ALD via elevated C26:0-lysophosphatidylcholine. Though the pathophysiology of how transplacental maternal anti-Ro antibodies damage fetal tissue is not well-understood, we postulate that the VLCFA elevations reflect a systemic inflammatory response and secondary peroxisomal dysfunction that improves once maternal autoantibodies wane after birth. Additional evaluation of this phenomenon is warranted to better understand the intricate biochemical, clinical, and possible therapeutic overlap between autoimmunity, inflammation, peroxisomal dysfunction, and human disease.

Neonatal lupus erythematosus (NLE) is a congenital autoimmune condition in which the transplacental passage of immunoglobulin G (IgG) directed against auto-antigens causes clinical symptoms in the foetus or neonate. Anti-Ro/SS-A, anti-La/SS-B, and to a lesser extent, anti-U1RNP autoantibodies (aAbs) have the strongest association with NLE. However, ~ 50% of affected mothers are asymptomatic despite carrying those aAbs. The clinical picture of the disease is very diverse. Cardiac manifestations are the most severe, including congenital heart block (CHB), with a mortality rate of ~18%. Preventative therapy with hydroxychloroquine (HCQ) reduces the recurrence rate of CHB in subsequent pregnancies by ~50%.
