Abstract
Maternal autoimmune disease is the most common cause of congenital heart block (CHB), a rare illness characterized by fibrosis and calcification of the fetal atrioventricular (AV) node due to maternal autoantibodies anti-SSA/Ro and anti-SSB/La. We report the full autopsy and clinical information on a female neonate with high degree AV block and calcification in the AV node, atrial approaches to the AV node, and both right and left bundle branches, born to a 27-year-old female with subclinical autoimmune disease.

Liu WL, Peng YH. Case Report: Bradycardia in neonatal lupus: differential diagnosis between atrioventricular block and premature atrial contractions with block. Front Pediatr 2024; 12:1337135.

Abstract
Neonatal lupus may be associated with severe cardiac conduction problems, including high-degree or complete atrioventricular (AV) block, necessitating immediate pacemaker implantation during the neonatal period. However, cardiac manifestations of neonatal lupus may extend beyond AV block. Our case was a full-term female neonate, who presented with fetal arrhythmia and bradycardia with a heart rate of approximately 70-75 beats per minute after birth. Neonatal lupus was diagnosed later due to positive maternal and neonatal anti-SSA/Ro antibody. High-degree AV block was considered initially but bigeminy premature atrial contractions (PACs) with block was confirmed through a detailed evaluation of an electrocardiogram, which demonstrated unfixed PP intervals and fixed RR intervals. Atrial tachycardia (AT) developed when the neonate was 23 days old. The key point that differentiates high-degree AV block from PACs with block is the PP interval. The PP interval is fixed in high-degree AV block and unfixed in PACs with block. Careful differential diagnosis is required in neonates with bradycardia because it may lead to very different management. Our case presents a good illustration of why these arrhythmias need to be differentiated. Furthermore, our case may be the first of neonatal lupus with AT.

Anti-Ro and anti-La seropositivity is associated with increased rates of ischemic heart disease in adults: Results from a large population-based study. Atherosclerosis 2024; 396:117626. [PMID: 39002391 DOI: 10.1016/j.atherosclerosis.2024.117626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 06/05/2024] [Accepted: 06/06/2024] [Indexed: 07/15/2024]
Abstract
BACKGROUND AND AIMS Emerging evidence suggests an arrhythmogenic effect of Anti-Ro/SSA (anti-Ro) and anti-La/SSB (anti-La) antibodies in adults, potentially involving a subclinical intracardiac inflammatory process. Despite the established association between inflammation and ischemic heart disease (IHD), it is noteworthy that as of now no study has delved into the potential link between these antibodies and IHD. This population-based study aimed to examine the association between anti-Ro/La seropositivity and IHD in the general adult population. METHODS We conducted a retrospective study using electronic medical records from the largest health maintenance organization in Israel. Patients with positive serology for either or both anti-Ro and anti-La antibodies were included, along with matched controls. Multivariate logistic regression models were utilized to assess the odds of IHD in seropositive patients compared to controls. RESULTS Among 17,231 seropositive patients and 84,368 controls, the rate of IHD was significantly higher in the seropositive group (9.7 % vs. 8.1 %,OR = 1.23; 95%CI 1.14-1.31; p<0.001). The association was more pronounced in younger patients [<40 years old (OR = 3.36; 95%CI 1.66-6.82; p<0.001), 40-49 years old (OR = 1.85; 95%CI 1.26-2.73; p<0.01), 50-59 years old (OR = 1.87; 95%CI 1.55-2.26; p<0.001), 60-69 years old (OR = 1.26; 95%CI 1.11-1.42; p<0.001), ≥70 years old (OR = 1.11; 95%CI 1.03-1.20; p<0.01)], as well as in patients with fewer traditional cardiovascular risk-factors (none:OR = 1.29; 95 % CI 1.09 to 1.77; p<0.01, 1-2:OR = 1.30; 95 % CI 1.19 to 1.41; p<0.001, ≥3:OR = 1.09; 95 % CI 0.99 to 1.21; p=0.076). CONCLUSIONS Our study demonstrates for the first time a positive association between anti-Ro/La seropositivity and IHD in the general adult population, especially among younger individuals with fewer traditional cardiovascular risk factors.

Abstract
Neonatal lupus erythematosus (NLE) is an autoimmune disease caused by the transplacental passage of anti-Ro/SS-A and anti-La/SS-B. This can be less commonly seen with U1-ribonucleoprotein (U1RNP). Our patient is a 7-day-old male, who first presented with seizures. In addition, during an electroencephalogram, he was found to have an irregular heart rhythm. Looking further into the history, we found that the mother was aware that she had systemic lupus erythematosus (SLE). However, she had not been followed up with a rheumatologist. The workup for NLE found a negative anti-Ro/SS-A and anti-La/SS-B, with a positive U1RNP-70kD. U1RNP-70kD is a diagnostic test for mixed connective tissue disease in adults, but no research has been done on its significance in NLE. Despite having SLE, the infant's mother did not receive surveillance during her pregnancy, as the current guidelines are tailored for mothers with anti-Ro/SS-A and anti-La/SS-B. As a result, this calls for the extension of these guidelines to include the U1RNP-70kD antibody. In this case, the 70kD subtype of U1RNP was positive, which may have had a role to play in this unusual presentation. However, further research is needed to improve the care of mothers and babies with U1RNP-70kD.

Anti-Ro/SSA Antibodies Blocking Calcium Channels as a Potentially Reversible Cause of Atrioventricular Block in Adults. JACC Clin Electrophysiol 2023; 9:1631-1648.

Abstract
BACKGROUND In ∼50% of severe atrioventricular blocks (AVBs) occurring in adults <50 years, the underlying etiology remains unknown. Preliminary evidence from case reports suggests that autoimmunity, specifically the presence of circulating anti-Ro/SSA antibodies in the patient (acquired form), in the patient's mother (late-progressive congenital form), or in both (mixed form), could be involved in a fraction of idiopathic AVBs in adults by possibly targeting the L-type calcium channel (Cav1.2) and inhibiting the related current (ICaL). OBJECTIVES The purpose of this study was to evaluate whether anti-Ro/SSA antibodies are causally implicated in the development of isolated AVBs in adults. METHODS Thirty-four consecutive patients with isolated AVB of unknown origin and 17 available mothers were prospectively enrolled in a cross-sectional study. Anti-Ro/SSA antibodies were assessed by fluoroenzyme-immunoassay, immuno-Western blotting, and line-blot immunoassay. Purified immunoglobulin-G (IgG) from anti-Ro/SSA-positive and anti-Ro/SSA-negative subjects were tested on ICaL and Cav1.2 expression using tSA201 and HEK293 cells, respectively. Moreover, in 13 AVB patients, the impact of a short course of steroid therapy on AV conduction was evaluated. RESULTS Anti-Ro/SSA antibodies, particularly anti-Ro/SSA-52kD, were found in 53% of AVB-patients and/or in their mothers, most commonly an acquired or mixed form (two-thirds of cases) without history of autoimmune diseases. Purified IgG from anti-Ro/SSA-positive but not anti-Ro/SSA-negative AVB patients acutely inhibited ICaL and chronically down-regulated Cav1.2 expression. Moreover, anti-Ro/SSA-positive sera showed high reactivity with peptides corresponding to the Cav1.2 channel pore-forming region. Finally, steroid therapy rapidly improved AV conduction in AVB-patients with circulating anti-Ro/SSA antibodies but not in those without. CONCLUSIONS Our study points to anti-Ro/SSA antibodies as a novel, epidemiologically relevant and potentially reversible cause of isolated AVB in adults, via an autoimmune-mediated functional interference with the L-type calcium channels. These findings have significant impact on antiarrhythmic therapies by avoiding or delaying pacemaker implantation.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune condition characterized by multi-organ involvement. The clinical presentation often varies from mild to moderate to severe. The cardiovascular system may also be affected, often portending a poor prognosis for patients. Although the relationship between SLE and cardiovascular disorders has been extensively explored through case reports and literature reviews, few systematic reviews explicitly focusing on this association have been conducted. In light of this, this systematic review aims to analyze the extent of the association between SLE and cardiovascular diseases (CVDs), by exploring the risk of developing CVDs, including myocardial infarction (MI), atherosclerosis, myocarditis, pericarditis and arrhythmias, in SLE patients vs. non-SLE patients. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to perform the systematic review. A detailed search was done covering the period from March 2003 to March 2023 using three databases: PubMed, Google Scholar, and Cochrane. The PubMed search identified 597 articles, while Google Scholar and Cochrane searches yielded 559 and three articles, respectively. Of the 1159 articles retrieved, we chose eight for final consideration, after excluding papers that did not discuss the role of SLE in CVDs, papers published earlier than 2003, and papers with incomplete data. The eight studies chosen included two narrative reviews, two systematic reviews, and four observational studies. In this systematic review, SLE was proven to have a strong relationship with diverse CVDs, including rare ones scarcely discussed in the literature, such as vasculitis and aortic dissection. All eight of the final papers indicated a connection between SLE and CVDs, based on the systematic analysis of these articles, which revealed that most recent research supports a higher risk of peripheral arterial occlusive disease (PAOD), MI, pericarditis, myocarditis, and other cardiovascular disorders in individuals with SLE. These associations may have certain gray areas, as patient characteristics and comorbidities often affect the extent of illness and long-term prognosis. Larger-scale studies are required to probe this relationship further and research the etiopathogenesis involved in order to improve patient outcomes. The effects of SLE on the heart are, however, unequivocal.

Abstract
OBJECTIVES To analyze the clinical characteristics, echocardiographic features, and prognosis of fetuses based on three groups of cardiac manifestations associated with maternal anti-Ro and anti-La antibodies in China. This study included three groups: the isolated-arrhythmia, isolated-endocardial fibroelastosis (EFE), and mixed groups. METHODS We prospectively evaluated 36 fetuses with cardiac manifestations due to maternal anti-Ro and anti-La antibodies from our center between 2016 and 2020 in China. Clinical and echocardiographic data were collected. RESULTS There were 13 patients (36%) in the isolated-arrhythmia group, eight (22%) in the isolated-EFE group, and 15 (42%) in the mixed group. All patients in the isolated-EFE group presented with mild EFE. Severe EFE was identified in four patients (27%) in the mixed group. Atrioventricular block (AVB) was more common in the isolated-arrhythmia group (13, 100%) than in the mixed group (6, 40%; p = 0.001). Moderate-severe mitral regurgitation (p = 0.006), dilated cardiomyopathy (DCM, p = 0.017), and low cardiovascular profile scores (p = 0.013) were more common in the mixed group than in the other two groups. Twenty-one mothers decided to terminate the pregnancy and 15 fetuses were born with regular perinatal treatment. They all survived at 1 year of age. One patient in the isolated-arrhythmia group and two in the mixed group required a pacemaker due to third-degree AVB or atrioventricular junctional rhythm. Five patients in the isolated-EFE group and five in the mixed group had no DCM or heart failure and the location of mild EFE was significantly reduced. CONCLUSION Fetal cardiac manifestations due to maternal anti-Ro and anti-La antibodies can be divided into three groups, i.e., the isolated-arrhythmia, isolated-EFE, and mixed groups. AVB usually occurs in the isolated-arrhythmia group. Severe EFE, moderate-severe mitral regurgitation, and DCM mainly appear in the mixed group. Location of mild EFE significantly reduces after birth and the outcome of fetuses with mild EFE depends on the presence of arrhythmia and its subtypes.

Abstract
A fetal autoimmune-mediated atrioventricular block is a passively acquired autoimmune disease in which maternal autoantibodies enter the fetal circulation via the placenta and subsequently cause inflammation and fibrosis of the atrioventricular node. Once fetal autoimmune-mediated atrioventricular block occurs, it only takes a short time to progress from first-degree atrioventricular block to complete atrioventricular block, meaning that the damage is often irreversible. Autoimmune-associated AVB, a rare but life-threatening disorder, occurs in 2-5% of pregnancies with positive anti-Ro/SSA (the most common one) and La/SSB antibodies. The perinatal mortality of neonates with AVB outlined in research is approximately 30%. Thus far, for autoimmune-associated AVB fetuses, currently used treatments include corticosteroids, hydroxychloroquine, intravenous immunoglobulin (IVIG), b-sympathomimetic agent, and even plasma exchange. Currently, approaches for preventing the progression and recurrence of a fetal atrioventricular block are still controversial. Here, we reported a baby of successful prevention from the fate of the fetal atrioventricular block by adopting prophylactic comprehensive prenatal therapy.

Abstract
TRIM21 (Ro52/SSA1) is an E3 ubiquitin ligase with key roles in immune host defence, signal transduction, and possibly cell cycle regulation. It is also an autoantibody target in Sjögren's syndrome, systemic lupus erythematosus, and other rheumatic autoimmune diseases. Here, we summarise the structure and function of this enzyme, its roles in innate immunity, adaptive immunity and cellular homeostasis, the pathogenesis of autoimmunity against TRIM21, and the potential impacts of autoantibodies to this intracellular protein.

Am J Physiol Heart Circ Physiol 2021; 321:H294-H305.

Abstract
The etiology of ethanol-related congenital heart defects has been the focus of much study, but most research has concentrated on cellular and molecular mechanisms. We have shown with optical coherence tomography (OCT) that ethanol exposure led to increased retrograde flow and smaller atrioventricular (AV) cushions compared with controls. Since AV cushions play a role in patterning the conduction delay at the atrioventricular junction (AVJ), this study aims to investigate whether ethanol exposure alters the AVJ conduction in early looping hearts and whether this alteration is related to the decreased cushion size. Quail embryos were exposed to a single dose of ethanol at gastrulation, and Hamburger-Hamilton stage 19-20 hearts were dissected for imaging. Cardiac conduction was measured using an optical mapping microscope and we imaged the endocardial cushions using OCT. Our results showed that, compared with controls, ethanol-exposed embryos exhibited abnormally fast AVJ conduction and reduced cushion size. However, this increased conduction velocity (CV) did not strictly correlate with decreased cushion volume and thickness. By matching the CV map to the cushion-size map along the inflow heart tube, we found that the slowest conduction location was consistently at the atrial side of the AVJ, which had the thinner cushions, not at the thickest cushion location at the ventricular side as expected. Our findings reveal regional differences in the AVJ myocardium even at this early stage in heart development. These findings reveal the early steps leading to the heterogeneity and complexity of conduction at the mature AVJ, a site where arrhythmias can be initiated.NEW & NOTEWORTHY To the best of our knowledge, this is the first study investigating the impact of ethanol exposure on the early cardiac conduction system. Our results showed that ethanol-exposed embryos exhibited abnormally fast atrioventricular conduction. In addition, our findings, in CV measurements and endocardial cushion thickness, reveal regional differences in the AVJ myocardium even at this early stage in heart development, suggesting that the differentiation and maturation at this site are complex and warrant further studies.

Abstract
Background: The rapid progression from fetal first-degree atrioventricular block (AVB) to third-degree AVB had been reported. However, how to define fetal first-degree AVB with proper technique and the necessity of the treatment in utero for fetal autoimmune-associated first-degree AVB are still controversial. Purpose: To explore the diagnosis and the effect of treatment for fetal first-degree AVB. Cases Presentation: Four pregnant women with positive autoantibodies anti-SSA/Ro were admitted into our hospital with complaints of rapid prolonged atrioventricular (AV) intervals of their fetuses. Fetal AV intervals were re-measured by tissue Doppler imaging (TDI) from the onset of atrial contraction to ventricular systole (Aa-Sa), which were 170 ms (case 1-twin A), 160 ms (case 1-twin B), 163 ms (case 2) and 172 ms (case 3) and 170 ms (case 4), respectively. The histories of medication usage or infection during gestation were denied. Amniotic fluid genetic screenings and virological tests were negative in all cases. No structural cardiac disorders were found and the cardiovascular profile scores were 10 for each fetus. Oral dexamethasone (initial dose of 4.5 mg daily) and hydroxychloroquine (200 mg bid) plus weekly follow-up surveillance were suggested. The dosage of dexamethasone was adjusted according to the changes of the AV intervals and fetal development of biparietal diameters (BPD) and femur lengths (FL). All fetal AV intervals were controlled well. Maternal and fetal adverse effects were noted as diabetes in 1 mother and growth retardation in all fetuses. All fetuses were delivered via cesarean section at 35+4, 37, 38, and 37+1 gestational weeks, with 10 scores of Apgar score. Postnatally, positive anti-SSA/Ro was found in all neonates. However, there were no clinical or laboratory evidence of neonatal lupus syndrome. No abnormal signs were found on postnatal electrocardiogram and echocardiography for all neonates. With a follow-up of 8–53 months, there was no progression of disease and all infants demonstrated normal physical, mental, and motor development. Conclusion: Prenatal treatment for fetal autoimmune-associated first-degree AVB could be an alternative. Strict surveillance and timely adjustment of the treatment according to the conditions of the mother and the fetus are indicated. Further studies are necessary to prove our concept.

Abstract
Systemic autoimmune conditions may cause morbidity and mortality. Systemic lupus erythematosus (SLE) is a prominent example of such diseases. It can result in conduction abnormalities due to accelerated atherosclerosis, vasculitis, or autoantibodies-induced myocarditis. Cardiac conduction abnormalities may produce sinus tachycardia, sinus bradycardia, prolonged QT intervals, atrial fibrillation, or atrioventricular (AV) nodal blocks. Neonatal lupus is sometimes associated with anti-Ro/SSA and anti-La/SSB antibodies, but their role remains a matter of controversy in adults.

Abstract
Primary Sjögren's syndrome (pSS) is a chronic systemic autoimmune rheumatic disease characterized by lymphoplasmacytic infiltration of the salivary and lacrimal glands, whereby sicca syndrome and/or systemic manifestations are the clinical hallmarks, associated with a particular autoantibody profile. pSS is the most frequent connective tissue disease after rheumatoid arthritis, affecting 0.3-3% of the population. Women are more prone to develop pSS than men, with a sex ratio of 9:1. Considered in the past as innocent collateral passive victims of autoimmunity, the epithelial cells of the salivary glands are now known to play an active role in the pathogenesis of the disease. The aetiology of the "autoimmune epithelitis" still remains unknown, but certainly involves genetic, environmental and hormonal factors. Later during the disease evolution, the subsequent chronic activation of B cells can lead to the development of systemic manifestations or non-Hodgkin's lymphoma. The aim of the present comprehensive review is to provide the current state of knowledge on pSS. The review addresses the clinical manifestations and complications of the disease, the diagnostic workup, the pathogenic mechanisms and the therapeutic approaches.

Abstract
The presence of maternal Anti-Ro/Anti-La antibodies causes a passively acquired autoimmunity that may be associated with serious fetal complications. The classic example is the autoimmune-mediated congenital heart block (CHB) which is due in most cases to the transplacental passage of Anti-Ro/Anti-La antibodies. The exact mechanisms through which these pathologic events arise are linked to disturbances in calcium channels function, impairment of calcium homeostasis and ultimately apoptosis, inflammation and fibrosis. CHB still represents a challenging diagnosis and a source of debate regarding the best management. As the third-degree block is usually irreversible, the best strategy is risk awareness and prevention. Although CHB is a rare occurrence, it affects one in 20,000 live births, with a high overall mortality rate (up to 20%, with 70% of in utero deaths). There is also concern over the lifelong consequences, as most babies need a pacemaker. This review aims to offer, apart from the data needed for a better understanding of the issue at hand, a broader perspective of the specialists directly involved in managing this pathology: the rheumatologist, the maternal-fetal specialist and the cardiologist. To better illustrate the theoretical facts presented, we also include a representative clinical case.

Abstract
OBJECTIVES Cardiac manifestations of neonatal lupus (NL) have been associated with significant morbidity and mortality; however, there is minimal information on long-term outcomes of affected individuals. This study was initiated to evaluate the presence of and the risk factors associated with cardiac dysfunction in NL after birth in multiple age groups to improve counselling, to further understand pathogenesis and to provide potential preventative strategies. METHODS Echocardiogram reports were evaluated in 239 individuals with cardiac NL: 143 from age 0-1 year, 176 from age >1-17 years and 64 from age >17 years. Logistic regression analyses evaluated associations of cardiac dysfunction at each age group with demographic, fetal and postnatal factors, using imputation to address missing data. RESULTS Cardiac dysfunction was identified in 22.4% at age 0-1 year, 14.8% at age >1-17 years and 28.1% at age >17 years. Dysfunction in various age groups was significantly associated with male sex, black race, lower fetal heart rates, fetal extranodal cardiac disease and length of time paced. In 106 children with echocardiograms at ages 0-1 year and >1-17 years, 43.8% with dysfunction at age 0-1 year were also affected at age >1-17 years, while the others reverted to normal. Of children without dysfunction at age 0-1 year, 8.9% developed new dysfunction between ages >1 and 17 years. Among 34 with echocardiograms at ages >1-17 years and >17 years, 6.5% with normal function at age >1-17 years developed dysfunction in adulthood. CONCLUSIONS Risk factors in fetal life can influence cardiac morbidity into adulthood.Although limited by a small number of cases, cardiac dysfunction in the first year often normalises by later childhood. New-onset dysfunction, although rare, can occur de novo after the first year.

Abstract
Autoimmune-mediated congenital heart block (CHB) is a severe manifestation of neonatal lupus in which conduction tissues of the fetal heart are damaged. This occurs due to passive transference of maternal anti-SSA/Ro and anti-SSB/La autoantibodies and subsequent inflammation and fibrosis of the atrioventricular (AV) node. Notably, the disease manifests after the fetal heart has structurally developed, ruling out other anatomical abnormalities that could otherwise contribute to the block of conduction. Complete AV block is irreversible and the most common manifestation of CHB, although other cardiac complications such as endocardial fibroelastosis (EFE), dilated cardiomyopathy, and valvular insufficiency have been observed. In this review, we detail the classification, prevalence, pathogenesis, and clinical management recommendations for autoimmune CHB.

Abstract
Background Conduction disturbances other than heart block related to neonatal lupus are rarely explored and reported in children with systemic lupus erythematosus (SLE). Objective To report the electrocardiographic (ECG) abnormalities in children with SLE and assess whether anti-Ro/SSA antibodies and hydroxychloroquine are associated with the rhythm disturbances. Methods This cross-sectional retrospective study comprised patients with SLE who had regular follow-up in the Pediatric Lupus Clinic at King Faisal Specialist Hospital and Research Center-Riyadh. All enrolled patients were evaluated with regard to demographics, age at disease onset, disease duration, clinical and laboratory variables including autoantibodies, disease activity using SLEDAI disease activity index, and medications. An expert pediatric cardiologist reviewed the ECG findings of all enrolled patients independently without knowing the clinical status of the patients. Results A total of 41 (35 females, 6 males) unselected patients with SLE with a mean age of 12.8 (2.5) years and mean follow-up duration of 4 (3) years completed the evaluation. The most frequent manifestations were renal disease (65.8%), followed by musculoskeletal (46.3%), hematological (41.5%), and cardiac involvement (19.5%). Thirty-two had active disease (SLEDAI >4), and the mean of SLEDAI was 9.2 (6.2). ECG abnormalities were seen in 12 patients (29.3%); these changes included ST-T changes (9.8%), right bundle branch block (7.3%), 4 prolonged QT interval (9.8%), and low QRS voltage (2.4%). Thirty-seven (90.3%) patients were on hydroxychloroquine, and 9 patients (22%) had positive anti-Ro/SSA antibodies. ECG abnormalities were associated significantly with anti-Ro/SSA antibodies (P < .05) and a low platelet count (P < .5) but had no association with other autoantibodies, hydroxychloroquine, or SLEDAI score. Conclusion Children with SLE with anti-Ro/SSA antibodies are probably prone to heart conduction abnormalities. However, the heart rate and QT interval were affected by hydroxychloroquine. A larger prospective study is required to allow more definitive conclusions.

Abstract
RATIONALE Neonatal lupus erythematosus (NLE) is an infrequent disease caused by transplacental maternal autoantibodies. The most common effects of NLE include cutaneous involvement and congenital heart block (CHB), although it might involve multiple organs, such as the liver, lungs, blood, and nervous or digestive systems. Izmirly PM1 and Tonello et al recently reported cutaneous manifestations of neonatal lupus and risk of subsequent CHB. The most serious complication of NLE is complete atrioventricular (AV) block. PATIENT CONCERNS We experienced 2 cases of NLE that were diagnosed in the past year in our Neonatal Intensive Care Unit. These cases showed 2 different clinical spectrums (CHB, multisystemic effects). One case was a 32-week pregnant woman with combined liver damage and fever, and her fetus was premature due to bradycardia and pericardial effusion. The second case was a young pregnant woman who had systemic lupus erythematosus for 2 years and had been taking methylprednisolone and hydroxychloroquine for a long time since her illness. When prenatal testing at 28 weeks of pregnancy showed that the fetus had CHB, the mother began taking dexamethasone. DIAGNOSIS The first case was diagnosed as NLE with CHB after birth, while the second was diagnosed as NLE with CHB, ductus arteriosus, and atrial septal defect when she was born at 34 weeks. INTERVENTIONS Both of 2 cases were treated with steroids, intravenous immunoglobulin, and a diuretic. But the second case was treated with isoprenaline in addition to the above. OUTCOMES Both of the infants was followed up and found to be clinically normal. During the clinic follow-up of the first case, the 8-month-old infant was still asymptomatic with normal growth and development. Her heart rate fluctuated from 40 to 90 beats/minute. LESSONS Autoimmune CHB is a severe, potentially life-threatening disorder associated with passive transfer of maternal anti-Sjogren's syndrome A/Ro and anti-Sjogren's syndrome B/La autoantibodies. Mothers who are positive for these autoantibodies are recommended to have serial echocardiography and obstetric ultrasonography from the early second trimester. Newborns should be delivered at an early stage of gestation if there is evidence of pericardial effusion, ascites, increasing ventricular ectopy, reduced ventricular shortening fraction, or AV valve regurgitation. Aggressive medical management after birth should be coupled with pacemaker implantation in infants who do not respond to medical therapies alone.

Abstract
OBJECTIVE Congenital heart block (CHB) is a rare but life-threatening disorder. More than half of CHB cases are associated with maternal autoimmune, which are termed as autoimmune-associated CHB. This review summarized the recent research findings in understanding autoimmune-associated CHB, discussed the current diagnostic approaches and management strategies, and summarized the problems and future directions for this disorder. DATA SOURCES We retrieved the articles published in English from the PubMed database up to January 2017, using the keywords including "Autoimmune-associated", "Autoimmune-mediated", and "Congenital heart block". STUDY SELECTION Articles about autoimmune-associated CHB were obtained and reviewed. RESULTS Observational studies consistently reported that transplacental maternal antibodies might recognize fetal or neonatal antigens in various tissues and result in immunological damages, but the molecular mechanisms underlying CHB pathogenesis still need illuminated. Multiple factors were involved in the process of atrioventricular block development and progression. While several susceptibility genes had been successfully defined, how these genes and their protein interact and impact each other remains to be explored. With currently available diagnostic tools, fetal ultrasound cardiography, and fetal magnetocardiography, most of CHB could be successfully diagnosed and comprehensively evaluated prenatally. The efficacy of current approaches for preventing the progression and recurrence of CHB and other autoimmune-mediated damages was still controversial. CONCLUSIONS This review highlighted the relationships between autoimmune injuries and CHB and strengthened the importance of perinatal management and therapy for autoimmune-associated CHB.

Abstract
A 57-year-old female patient with underlying hypertension, dyslipidemia, membranous glomerulonephritis, and Sjögren's syndrome presented to our clinic with near-syncope and dizziness symptoms. We detected non-conducted sinus beat in 12-lead electrocardiography. An echocardiography showed that the left ventricular systolic function was preserved without a regional wall abnormality. The patient did not have symptoms of congestive heart failure or recent myocardial infarction. We observed complete atrioventricular block with longest pause of 6.2 seconds in a 24-hour Holter electrocardiography, and subsequently implanted a permanent pacemaker. Anti-Ro/Sjögren's syndrome type A antibodies are commonly seen in Sjögren's syndrome and associated with a neonatal complete heart block. The pathogenesis of anti-Ro/Sjögren's syndrome type A antibodies in the conduction system of an adult heart is still uncertain. In this article, we report Sjögren's syndrome in an adult patient with complete atrioventricular block and membranous glomerulonephritis, which may be associated with a positive titer of anti-Ro/Sjögren's syndrome type A antibodies.

Abstract
INTRODUCTION Congenital complete heart block affects 1/15,000 live-born infants, predominantly due to atrioventricular nodal injury from maternal antibodies of mothers with systemic lupus erythermatosus or Sjogren's syndrome. The majority of these children will need a pacemaker implanted prior to becoming young adults. This article will review the various patient and technical factors that influence the type of pacemaker implanted, and the current literature on optimal pacing practices. Areas covered: A literature search was performed using PubMed, Embase and Web of Science. Data regarding epicardial versus transvenous implants, pacing-induced ventricular dysfunction, alternative pacing strategies (including biventricular pacing, left ventricular pacing, and His bundle pacing), and complications with pacemakers in the pediatric population were reviewed. Expert commentary: There are numerous pacing strategies available to children with congenital complete heart block. The risks and benefits of the initial implant should be weighed against the long-term issues inherent with a life-time of pacing.

Abstract
Objectives Cardiovascular disease (CVD) is a leading cause of death in systemic lupus erythematosus (SLE) and in rheumatoid arthritis (RA). Although only explored in one study, ECG non-specific ST-T abnormalities, in addition to corrected QT-interval (QTc) prolongation, were recently reported in an SLE inception cohort. Importantly, these ECG abnormalities are known predictors of CVD mortality in the general population, yet their prevalence in patients with established SLE has not been evaluated. Methods We cross-sectionally investigated the presence of non-specific ST-T and QTc abnormalities in 50 patients with SLE, predominantly Hispanic and black, without CVD or SLE-related cardiac involvement and compared them with 139 patients with RA without CVD. Demographics, disease-specific characteristics and CVD risk factors were ascertained and adjusted for. Results Patients with SLE (mean age 36±13 years, 92% women, 6 years median disease duration, 96% Hispanics and blacks) had a 3.3-fold higher adjusted prevalence of non-specific ST-T abnormalities (56% vs 17%; p <0.0001) compared with RA, despite the older age and higher percentage of men in the RA group. The QTc was 26 ms longer in SLE compared with RA (p=0.002) in the setting of a higher percentage of women, blacks, Hispanics and higher C reactive protein levels in the SLE group. Conclusions This study demonstrates a high prevalence of ECG abnormalities in predominantly Hispanic and black patients with SLE. Longitudinal evaluation of the progression to potentially life-threatening arrhythmias and/or cardiovascular events is warranted.

Abstract
Autoimmune congenital heart block (ACHB) is an immune-mediated cardiac disease included among the manifestations collectively referred to as neonatal lupus. The placental transference of maternal Ro/La autoantibodies may damage the conduction tissues during fetal development leading to blocking of signal conduction at the atrioventricular (AV) node in an otherwise structurally normal heart. Irreversible complete AV block is the main cardiac manifestation of ACHB, but some babies may develop endocardial fibroelastosis, valvular insufficiency, and/or frank cardiomyopathies with significantly reduced cardiac function requiring transplant. The severity of ACHB is illustrated by a global mortality rate of 20% and pacemaker rates of at least 64%, often within the first year of life. This review analyses the main complex and/or unusual clinical situations associated with ACHB, including unusual maternal immunological profiles, infrequent maternal autoimmune diseases, cardiac damage unrelated to AV block, fetal invasive management, late complications after birth, risk of congenital heart block (CHB) in ovodonation and in vitro fertilization techniques, the role of maternal features other than autoimmunity, the influence of the birth order or the risk of CHB in twins and triplets.

Abstract
The objective of this study was to describe the clinical and immunological characteristics of maternal autoimmune-mediated fetal congenital heart block (CHB) in a cohort of pregnant women from an autoimmune disease pregnancy clinic. This is a retrospective observational study of all women presenting with CHB in our autoimmune disease pregnancy clinic from January 1997 to December 2014. In addition, perinatal outcome is also described. Fourteen patients accounting for 18 fetuses with CHB were identified. The median age was 32.5 years (range, 22-40). Seven (50 %) patients had Sjögren's syndrome, and the remaining seven were asymptomatic carriers of autoantibodies. All patients had anti-Ro/SSA antibodies, and 11/13 (85 %) had anti-La/SSB antibodies. The median gestational age at the time of CHB was 22 weeks (range 18-28). Complete third degree CHB was detected in 12 (67 %). Seven cases of CHB were treated with dexamethasone, two with ritodrine, and one with the association of dexamethasone, ritodrine, and terbutaline. In 9 (50 %) cases that presented with, or developed, very poor prognosis factors, such as a ventricular rate below 50-55 bpm and/or the presence of fetal hydrops, parents opted for the termination of pregnancy, after dedicated counseling. Finally, there were nine newborns (seven males [78 %]) with median age at delivery of 37 weeks (range, 32-39). A definitive epicardial pacemaker was placed in six newborns, four of them within 2 weeks of life. CHB is a severe complication related to maternal anti-Ro/SSA and anti-La/SSB antibodies. Our results confirm previous data showing that therapy is ineffective, and most of the surviving patients will require neonatal pacemaker.

Abstract
Autoimmune congenital heart block (CHB) is an immune-mediated acquired disease that is associated with the placental transference of maternal antibodies specific for Ro and La autoantigens. The disease develops in a fetal heart without anatomical abnormalities that could otherwise explain the block, and which is usually diagnosed in utero, but also at birth or within the neonatal period. Autoantibody-mediated damage of fetal conduction tissues causes inflammation and fibrosis and leads to blockage of signal conduction at the atrioventricular (AV) node. Irreversible complete AV block is the principal cardiac manifestation of CHB, although some babies might develop other severe cardiac complications, such as endocardial fibroelastosis or valvular insufficiency, even in the absence of cardiac block. In this Review, we discuss the epidemiology, classification and management of women whose pregnancies are affected by autoimmune CHB, with a particular focus on the autoantibodies associated with autoimmune CHB and how we should test for these antibodies and diagnose this disease. Without confirmed effective preventive or therapeutic strategies and further research on the aetiopathogenic mechanisms, autoimmune CHB will remain a severe life-threatening disorder.

Abstract
Several case reports, small case series, and original research papers have recently suggested that the action of certain auto-antibodies related to connective tissue diseases may be responsible for significant cardiac rhythm disturbances in adults. The relationship between anti-Ro/SSA antibodies and congenital complete atrioventricular block is well recognized in the fetal heart. Herein we review the emerging evidences of the link to increased levels of anti-Ro/SSA antibodies with rhythm disorders of unknown origin in the adult. Confirmation of this distinct etiology may eventually be the basis for new therapies.

Abstract
Neonatal lupus (NL) is defined by the presentation of the fetus and the newborn who possess autoantibodies received from the mother. It is the dysfunction of the maternal immune system that leads to the production of autoantibodies to anti-Sjögren syndrome-A, anti-Sjögren syndrome-B, and anti-ribonuclear protein antigens. These antibodies are shared through the placenta and produce bodily changes in the fetal skin and heart, as well as potential changes in other body systems. Congenital complete heart block is the most dangerous manifestation of NL that can occur in utero or after birth. This article will provide an overview the presentation of NL and current therapies. Prenatal steroids have been the mainstay of therapy to try to reverse first- and second-degree congenital heart block and to prevent progression to a more advanced stage. New therapies are combining steroids with intravenous immunoglobulin and plasmapheresis. This article will provide guidelines for practitioners so they can consider NL as a differential diagnosis when presented with cutaneous lesions, congenital heart block, or abnormal findings in the hematologic, hepatobiliary, neurologic, and musculoskeletal systems.

Abstract
Human maternal autoantibodies can trigger autoimmune diseases such as congenital heart block (CHB) in the progeny of women with lupus or Sjogren’s disease. The pathogenic effect of early autoantibody (autoAb) exposure has been investigated in a murine neonatal autoimmune ovarian disease (nAOD) model triggered by a unique ZP3 antibody. Although immune complexes (IC) are formed in adult and neonatal ovaries, ZP3 antibody triggers severe nAOD only in <7-day-old neonatal mice. Propensity to nAOD is due to the uniquely hyper-responsive neonatal natural killer (NK) cells that lack the inhibitory Ly49C/I receptors. In nAOD, the neonatal NK cells directly mediate ovarian inflammation and oocyte depletion while simultaneously promoting de novo pathogenic ovarian-specific T cell responses. Resistance to nAOD in older mice results from the emergence of the Ly49C/I+ NK cells that regulate effector NK cells and from CD25+ regulatory T cell control. In preliminary studies, FcγRIII+ NK cells as well as the ovarian resident FcγRIII+ macrophages and/or dendritic cells were found to be as indispensable players. Activated by ovarian IC, they migrate to lymphoid organs where NK cell priming occurs. Remarkably, the findings in nAOD are very similar to those reported for neonatal responses to a retrovirus and its cognate antibody that lead to long-lasting immunity. Studies on nAOD therefore provide insights into maternal autoAb-mediated neonatal autoimmunity, including CHB, while simultaneously uncovering new properties of the neonatal innate and adaptive responses, lethality of premature infant infection, and novel neonatal antiviral vaccine design.

Abstract
BACKGROUND Autoantibody-related congenital heart block (CHB) is an autoimmune condition in which trans placental passage of maternal autoantibodies cause damage to the developing heart conduction system of the foetus. CASE PRESENTATION We report a case of an Italian 31-year-old woman, in a good clinical status, referred to our Centre at 26 weeks of her first pregnancy, because of foetal bradycardia, found during routine foetal ultrasonography. Foetal echocardiography revealed a 3rd degree CHB, without any anatomical defects. Despite the mother was asymptomatic for autoimmune disease, anti-Ro/La were searched for, because of the hypothesis of autoantibody-related CHB. High title of maternal anti-Ro/SSA antibodies was found and diagnosis of an autoantibody-related CHB was made. A combination treatment protocol of the mother was started with oral betamethasone, plasmapheresis and IVIG. An emergency C-section was performed at 32 + 3 weeks of gestation because of a non-reassuring cardiotocography pattern. A male newborn (BW 1515 g, NGA, Apgar 8-10) was treated since birth with high-flow O2 for mild RDS. IVIG administration was started at one week, and then every two weeks, until complete disappearance of maternal antibodies from blood. Because of persistent low ventricular rate (<60/min), seven days following birth, pacemaker implantation was performed. The baby is now at 40th week with no signs of cardiac failure and free of any medications. CONCLUSION Up to date, no guidelines have been published for the treatment of "in utero-CHB" and only anecdotal reports are available. It has been stated that a combination therapy protocol is effective in reversing a 2nd degree CHB, but not for 3rd degree CHB. In cases of foetal bradycardia, weekly foetal echocardiographic monitoring needs to be performed and in cases of 2nd degree CHB and 3rd degree CHB maternal therapy could be suggested, as in our case, to avoid foetal heart failure. In cases of 3rd degree CHB often pacemaker implantation is needed.
