Khayat AA, Alkhaldi AJ. Neonatal Lupus presenting with neonatal hemochromatosis-like liver disease that responded to steroids: a case report. BMC Pediatr 2022; 22:630. [PMID: 36329404 PMCID: PMC9632081 DOI: 10.1186/s12887-022-03713-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 10/25/2022] [Indexed: 11/06/2022] Open
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
Sjogren's syndrome (SS) is an autoimmune disease characterized by lymphocytic infiltration of the exocrine glands and other organs. Women with SS often experience gynecological symptoms due to the disease and need extra care regarding their sexual activity, reproductive health and during pregnancy, conditions that are not properly conducted in the clinical practice. To cover this gap, a panel of experts from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis on the identification of symptoms, diagnosis, monitoring, prognosis, and treatment of these manifestations. A Focus Group meeting was held and included experts in the field and methodologists, based on a previously developed script, with themes related to the objective of the study. The most important topics were summarized and 11 recommendations were provided.

Abstract
Aim Cirrhosis is rare in systemic lupus erythematosus (SLE) patients with a poor prognosis. This study is aimed at retrospectively analyzing our single-center experience to explore the characteristics of cirrhosis in SLE patients. Methods SLE patients with cirrhosis from 2012 to 2019 were enrolled. SLE diagnosis was rigorously confirmed by a medical record review according to the revised 1997 American College of Rheumatology classification criteria for SLE. The diagnosis of liver cirrhosis was based on a combination of clinical, laboratory, and imaging criteria features. We conducted a case-control study in SLE patients complicated with the cirrhosis group and the age-, sex-, and entry-time-matched noncirrhosis group. Results A total of 21 patients with SLE cirrhosis were enrolled, 3 males and 18 females. The median age at the time of cirrhosis diagnosis was 47.3 ± 4.0 years, and the mean disease duration of SLE before cirrhosis was 4.7 ± 1.0 years. The most common initial presentation was the involvement of the hematological system in 9 patients and then skin and mucosal involvement in 5 patients, arthritis in 4 patients, and nephritis in 3 patients. Patients with cirrhosis had a significantly higher rate of hematological system involvement (thrombocytopenia and leukopenia) and worse liver function; a higher level of immune globulin G had higher mortality (p < 0.05) than patients without cirrhosis. Conclusions Cirrhosis is a rare and severe subtype of SLE with a poor prognosis. Those patients with hematological system involvement and impaired liver function should be paid more attention.

Abstract
The neonatal lupus syndromes (NLS), while quite rare, carry significant mortality and morbidity in cases of cardiac manifestations. Although anti-SSA/Ro-SSB/La antibodies are detected in .85% of mothers whose fetuses are identified with congenital heart block (CHB) in a structurally normal heart, when clinicians applied this testing to their pregnant patients, the risk for a woman with the candidate antibodies to have a child with CHB was at or below 1 in 50. While the precise pathogenic mechanism of antibody-mediated injury remains unknown, it is clear that the antibodies alone are insufficient to cause disease and fetal factors are likely contributory. In vivo and in vitro evidence supports a pathologic cascade involving apoptosis of cardiocytes, surface translocation of Ro and La antigens, binding of maternal autoantibodies, secretion of profibrosing factors (e.g., TGFb) from the scavenging macrophages and modulation of cardiac fibroblasts to a myofibroflast scarring phenotype. The spectrum of cardiac abnormalities continues to expand, with varying degrees of block identified in utero and reports of late onset cardiomyopathy (some of which display endocardial fibroelastosis). Moreover, there is now clear documentation that incomplete blocks (including those improving in utero with dexamethasone) can progress postnatally, despite the clearance of the maternal antibodies from the neonatal circulation. Better echocardiographic measurements which identify first degree block in utero may be the optimal means of approaching pregnant women at risk. Prophylactic therapies, including treatment with intravenous immunoglobulin, await larger trials. In order to achieve advances at both the bench and bedside, national research registries established in the US and Canada are critical.

Abstract
Within the last decade the prevalence of adult patients living with congenital heart disease equals that seen in children. This expanding population poses a challenge to clinical cardiologists who will be caring for patients with the clinical manifestations of this condition. Neonatal lupus is a model of passively acquired autoimmunity and is responsible for the majority of clinical cases of congenital heart block (CHB). This review will focus on the presentation, pathophysiology, and the long-term follow-up of CHB associated with neonatal lupus, and discuss important diagnostic tests, familial implications, and pacemaker issues associated with the care of an adult with CHB.

Abstract
Neonatal autoimmune diseases are distinctly rare. Most neonatal autoimmune diseases result from the transplacental transfer of maternal antibodies directed against fetal or neonatal antigens in various tissues. In neonatal lupus, the heart seems to be particularly susceptible. Primary autoimmunity in newborns, with the exception of familial autoinflammatory diseases, is virtually non-existent. The pathophysiologic basis for the development of neonatal autoimmunity is not entirely clear, but differences in the neonatal immune system compared with the adult immune system, as well as unique characteristics of target antigens in the newborn period may be important factors. Neonatal lupus is the most common presentation of autoimmunity in the newborn. But the characteristics defining neonatal lupus are not well defined and the presentation of neonatal lupus differs from that of classical lupus. Other neonatal autoimmune diseases involving the interaction between maternal antibodies and fetal/neonatal antigens include neonatal anti-phospholipid syndrome, Behcet's disease, neonatal autoimmune thyroid disease, neonatal polymyositis and dermatomyositis, neonatal scleroderma and neonatal type I diabetes mellitus. While autoantibodies have been detected in patients with neonatal autoimmune disease, the pathogenic role of autoantibodies has not been well defined. Other mechanisms may play a role in the development of neonatal autoimmunity, including fetal/maternal microchimerism and aberrant apoptosis of fetal cells. The autoinflammatory syndromes are a completely different category, but are also included in discussion of neonatal autoimmune diseases. The autoinflammatory syndromes include the cryopyrin associated periodic syndromes (CAPS) - familial cold autoinflammatory syndrome (FCAS), neonatal onset multisystem inflammatory disease (NOMID) and Muckle-Wells syndrome, which all share a common pathophysiologic mechanism.

Abstract
OBJECTIVE To determine the prevalence of abnormal liver enzymes in patients with systemic lupus erythematosus (SLE) and whether further investigations were done, and the differences in SLE-related and/or metabolic factors in patients with and without liver biochemical abnormalities. METHOD Patients from the University of Toronto Lupus Clinic who met at least 4 of the American College of Rheumatology classification criteria for SLE and had 1.5 times the upper limit for aspartate transaminase or alanine transaminase on 2 consecutive visits within a 2-year period were matched with controls for age, sex, and SLE duration. Demographic, clinical, and laboratory data were extracted at the time of the first appearance of liver enzyme abnormality for the cases and at the reference point for the controls. RESULTS From the 1533 patients reviewed, 134 (8.7%) met the inclusion criteria. Thirty of these patients were evaluated by a hepatologist, 75 had imaging studies (41 were done specifically for liver investigation), and 13 had liver biopsies. Results based on these investigations showed 31 fatty livers, 35 cases of drug-induced hepatotoxicity, 10 autoimmune etiologies, and 3 cases of viral hepatitis. Compared to controls, cases were higher in body mass index, anti-dsDNA antibody, prevalence of hypertension, antiphospholipid syndrome, and use of immunosuppressive medication, especially azathioprine and methotrexate; they were lower in IgM. CONCLUSION Metabolic abnormalities such as obesity and hypertension and hepatotoxic effects of medication used to treat SLE may contribute more than SLE-related factors to liver biochemical abnormalities in patients with SLE.

Abstract
Anti-Ro/SSA antibodies are associated with neonatal lupus (congenital heart block (CHB), neonatal transient skin rash, hematological and hepatic abnormalities), but do not negatively affects other gestational outcomes, and the general outcome of these pregnancies is now good, when followed by experienced multidisciplinary teams. The prevalence of CHB, defined as an atrioventricular block diagnosed in utero, at birth, or within the neonatal period (0-27 days after birth), in the offspring of an anti-Ro/SSA-positive women is 1-2%, of neonatal lupus rash around 10-20%, while laboratory abnormalities in asymptomatic babies can be detected in up to 27% of cases. The risk of recurrence of CHB is ten times higher. Most of the mothers are asymptomatic at delivery and are identified only by the birth of an affected child. Half of these asymptomatic women develop symptoms of a rheumatic disease, most commonly arthralgias and xerophtalmia, but few develop lupus nephritis. A standard therapy for CHB is still matter of investigation, although fluorinated corticosteroids have been reported to be effective for associated cardiomyopathy. Serial echocardiograms and obstetric sonograms, performed at least every 1-2 weeks starting from the 16th week of gestational age, are recommended in anti-Ro/SSA-positive pregnant women to detect early fetal abnormalities that might be a target of preventive therapy.

Abstract
Congenital heart block (CHB) is a conduction abnormality that affects hearts of foetuses and/or newborn to mothers with autoantibodies reactive with the intracellular soluble ribonucleoproteins 48-kD La, 52-kD Ro and 60-kD Ro. CHB carries substantial mortality and morbidity, with more than 60% of affected children requiring lifelong pacemakers. Several hypotheses have been proposed to explain the pathogenesis of CHB. These can be grouped under three main hypotheses: Apoptosis, Serotoninergic and Ca channel hypothesis. Here, we discuss these hypotheses and provide recent scientific thinking that will most likely dominate the future of this field of research.

Abstract
Neonatal lupus erythematosus (NLE) is characterized by the transplacental passage of maternal anti-Ro and/or anti-La antibodies and characteristic illnesses in the foetus/neonate. Most attention has focused on the most serious complication- cardiac involvement. This article will focus on non-cardiac involvement. Skin involvement (cutaneous NLE) is present in 15-25% of children with NLE. The rash of NLE tends to be photosensitive but may be present at birth or in non-sun exposed areas. It is most frequently seen around the eyes, not in the malar area, but also occurs in other parts of the body. The pathology resembles the rash of subacute cutaneous lupus erythematosus. Anti-Ro antibodies are present in >95% with the remaining mothers having anti-U1RNP antibodies only. Asymptomatic elevation of liver function tests, which may be associated with evidence of cholestasis, is seen in 10-25% of cases of NLE. Mild hepatomegaly and less commonly splenomegaly may be present. Liver involvement seen in isolation or associated with other features. The pathology resembles idiopathic neonatal giant cell hepatitis. Any haematological lineage, neutropenia and thrombocytopenia most commonly, may be affected by NLE. Haematological involvement is almost always asymptomatic. There are protean manifestations of neurologic involvement in NLE: hydrocephalus, non-specific white matter changes, calcification of the basal ganglia and a 'vasculopathy'. The most unusual feature of NLE is the radiographic finding of stippling of the epiphyses (chondrodysplasia punctata). Overall, non-cardiac involvement of NLE is more common than cardiac. The study of these manifestations may lead to new insight into how autoantibodies lead to disease.

Abstract
To recognize the clinical characteristics and outcomes of neonatal lupus erythematosus (NLE), the authors retrospectively review 3 NLE babies in their department and compared their data with 51 NLE cases reported in the available Chinese literature between January 1991 and December 2008. Most of the cases were located near the eastern coast of China, and clinical manifestation of 72.22% of the cases occurred in 2-week-old babies. Skin findings occurred in 94.44% of the patients, 12.96% with complete heart block (CHB), 22.22% with thrombocytopenia, and 14.81% with transient elevated transaminase levels. Cutaneous lesions, thrombocytopenia, and transaminase level showed improvement; 3 CHB cases had persisted after 7 to 10 years follow-up, and 1 case died in 5 months. Twenty-four (44.44%) pregnant woman with anti-Ro/SSA and/or anti-La/SSB antibodies are asymptomatic, and antibody status is first indicated when their child shows symptoms of NLE. Thus, all pregnant women should be screened for anti-Ro/ SSA and anti-La/SSB antibodies.

The first 10 newborns born to mothers with connective tissue disease and positive for anti-SSA/Ro antibodies enrolled in a follow-up program to evaluate the incidence of cardiac, hepatobiliary, hematologic, echoencephalographic, and cutaneous manifestations until 9 months of age are described in this study. No congenital heart block was observed, but only transient rhythm alterations were observed. In all, 1 infant showed typical neonatal lupus syndrome skin lesions at 3 months of age. During the neonatal period, echoencephalographic alterations were found more frequently, whereas at follow-up, hepatic and hematologic alterations were more often observed. In all, 1 baby showed persistent neutropenia. A standard program that enrolls all infants born to mothers with anti-SSA/Ro autoantibodies, who are at risk of developing neonatal lupus syndrome, should also include tests performed some time after birth, as a number of clinical manifestations might appear at a late stage.

Abstract
Neonatal lupus has become an important model of passively acquired autoimmunity since the seminal observation in the late 1970s that sera from nearly all mothers of children with isolated congenital heart block (CHB) contain specific autoantibodies.

Abstract
OBJECTIVE Neurologic involvement has been reported to occur in infants with neonatal lupus erythematosus (NLE), although the significance of these findings is unknown. The purpose of this study was to determine if hydrocephalus/macrocephaly is a manifestation of NLE. METHODS Infants from the Hospital for Sick Children in Toronto, Canada whose mothers had anti-Ro antibodies were followed prospectively. A total of 87 infants were seen in the study period (1999-2004). The maternal autoantibody status of all infants was documented, and all infants underwent full clinical examination at each visit. RESULTS Of the 87 infants, 47 had NLE. Five of the 47 infants with NLE and 2 of the healthy infants had hydrocephalus, resulting in a prevalence of 8.0% (95% confidence interval 4.0-15.0%) in the entire cohort. This is significantly higher than the prevalence in the general population of 0.048-0.081%. Head circumference measurements of infants in the Toronto cohort were largest between 12-24 months of age (Z score difference = 0.71, P = 0.008). CONCLUSION We suggest that hydrocephalus and macrocephaly are manifestations of NLE and that infants born to mothers with anti-Ro antibodies should be carefully monitored for hydrocephalus as part of their routine physical examination.

Abstract
Congenital complete heart block can be isolated or can occur in association with other structural heart diseases. Isolated congenital complete heart block (CCHB) is due to transplacental transfer of autoantibodies from mothers with connective tissue disease. Congenital heart block is usually complete, but incomplete blocks, sinus bradycardia and QTc prolongation are also reported. Anti SS A and Anti SS B antibodies transferred from mothers have inflammatory and arrhythmogenic effects in the fetal conduction system. Cardiac manifestations reported include dilated cardiomyopathy, endocardial fibroelastosis and mitral insufficiency. Low ventricular rate, QT prolongation and arrhythmias on monitoring are high risk features. CCHB has a mortality of 30%, and 60% of infants require pacemaker therapy. Fetal echocardiography is useful in early diagnosis. Prophylactic steroid therapy is controversial. Beta adrenergic agonists were tried in mothers with fetuses having congenital heart block to increase fetal heart rate. Early pacemaker therapy is indicated in patients with symptomatic bradycardia and ventricular dysfunction. The indications for pacing in congenital heart block continue to evolve with advances in techniques and most of these children will ultimately require permanent pacemakers by adulthood.

Abstract
Neonatal lupus, although quite rare, carries a significant mortality and morbidity when the fetal heart is the targeted organ. Anti-SSA/Ro-SSB/La antibodies are present in more than 85% of mothers whose fetuses are identified with congenital heart block (CHB) in a structurally normal heart, but the risk for a woman who has the candidate antibodies to have a child who has CHB is approximately 2%. Although the precise pathogenic mechanism of injury remains unknown, it is clear that the antibodies alone are insufficient to cause disease, and fetal factors are likely contributory. In vivo and in vitro evidence supports a pathologic cascade, involving apoptosis of cardiocytes, surface translocation of Ro and La antigens, binding of maternal autoantibodies, secretion of profibrosing factors (eg, tumor growth factor ) from the scavenging macrophages, and modulation of cardiac fibroblasts to a myofibroblast-scarring phenotype. The spectrum of cardiac abnormalities encompasses varying degrees of block identified in utero and late-onset cardiomyopathy. Better echocardiographic measurements that identify first-degree block in utero may be the optimal approach for pregnant women at risk; prophylactic therapies, including treatment with intravenous immunoglobulin, await larger trials.

Abstract
Neonatal lupus syndrome is a passively acquired autoimmune syndrome in which pathogenic autoantibodies (anti-SSA/Ro, anti-SSB/La, and both, or rarely anti-U(1)RNP antibodies) are transmitted from a mother to her fetus through the placenta. The major clinical manifestations in the infants are cardiac (congenital heart block), dermatologic (skin lesion), hepatic (elevated hepatic enzymes), and hematologic (cytopenia). Congenital complete heart block (CCHB) is irreversible, while noncardiac manifestations are transient, resolving by one-year-old of age without specific treatments. Two prospective studies show that the prevalence of CCHB in children from a woman previously known to have anti-SSA/Ro antibodies is approximately 2%. However, when the previous pregnancy is complicated by CCHB and skin lesion, the recurrence rates of these symptoms go much higher to 10.5% and 26%, respectively, in the subsequent pregnancy.

Abstract
Few diseases exemplify the integration of research from bench to bedside as well as neonatal lupus, often described as a model of passively acquired autoimmunity. The signature histologic lesion of autoimmune congenital heart block (CHB) is fibrosis of the conducting tissue and, in some cases, the surrounding myocardium. Although anti-SSA/Ro-SSB/La antibodies are detected in > 85% of mothers whose fetuses are identified with conduction abnormalities in a structurally normal heart, the risk for a woman with the candidate antibodies to have a child with CHB is 2%. The mechanism by which maternal anti-SSA/Ro-SSB/La antibodies initiate and finally eventuate in atrioventricular nodal scarring is not yet defined, but it is clear that the antibodies alone are insufficient to cause disease and fetal factors are likely contributory. Previous in vitro and in vivo studies suggest that the pathologic cascade is initiated via apoptosis, resulting in translocation of SSA/Ro-SSB/La antigens to the cell surface where they are bound by maternal autoantibodies. Subsequently, the Fc portion of the bound immunoglobulin engages Fcgamma receptors on tissue macrophages, resulting in release of TGF-beta at a threshold favoring a profibrotic milieu and irreversible scarring. This cascade also involves tissue-specific activation of TGF-beta, which promotes the modulation of fibroblasts into myofibroblasts, a scarring phenotype. Recent findings point to genetic polymorphisms that promote high production of TGF-beta as possible fetal risk factors for CHB. Further elucidation of maternal and fetal contributory factors should provide insight into the pathogenesis of CHB and the rarity of irreversible injury.

Abstract
We evaluated the consequence of different types of fetal arrhythmia in the development of neonatal cholestasis. The charts of 38 children born at St. Justine Hospital between 1993 and 2001 with sustained and hemodynamically significant fetal arrhythmias were studied: 19 with supraventricular tachycardia, 14 with atrial flutter, and 5 with atrio-ventricular (AV) block. Six of these 38 children presented with cholestasis. The average duration of arrhythmia was 15.7 days in the noncholestatic group, compared with 40.3 days in the cholestatic group ( P <.05). The three infants with supraventricular tachycardia who developed cholestasis survived and resolved their cholestasis, whereas 2 of 3 infants with AV block died. No infant with atrial flutter developed cholestasis. We conclude that newborns who developed tachyarrhythmia during their fetal life can show transient neonatal cholestasis. In patients with AV block, severe and irreversible liver failure could be observed. In addition, extensive collapse of the stroma and the absence of hepatocytes (foie vide) also were observed in a patient with anti-Ro antibodies.

Abstract
Neonatal lupus Erythematosus (NLE) is a disorder characterized by maternal autoantibodies against RNA protein complex, Ro/SSA or SSB/La. These maternal IgG antibodies cross the placenta and potentially lead to fetal tissue damage and the clinical manifestations NLE. NLE is uncommon, affects females more than males, has no race predilection, and involves multiple organs. It has cutaneous manifestations similar to subacute cutaneous lupus erythematosus (SCLE). In addition to skin findings, patients with NLE have a significant risk of congenital heart block (CHB), a potentially fatal complication. Less frequently, hematologic and hepatic abnormalities occur. Approximately half of the reported cases have skin disease and half have CHB. Approximately 10% have both CHB and skin findings. The cutaneous, hematologic, and hepatic abnormalities are transient, clearing by 6 months of age. However, CHB is permanent and requires a pacemaker in many cases. The disorder results from the passive transfer of maternal autoantibodies, anti-RoSSA and anti-La/SSB. Sontheimer and McCauliffe reviewed the pathogenic role of anti-Ro antibody in NLE lesions and summarize evidence supporting its pathogenic role. Additional evidence suggests the possibility that Ro-antigen-specific T-cells may be present in SCLE patients and have the capacity to cause direct injury to the skin. McCuistion and Schoch first suggested this hypothesis in 1954 when they described an infant with LE skin findings born to a mother with systemic lupus erythematosus (SLE). Since this initial observation, a number of researchers have documented the role of maternal autoantibodies in the pathogenesis of this disorder. The true incidence of NLE is not known; however, it is known that NLE accounts for approximately 80% of all cases of CHB, and the incidence of CHB is 1 per 20,000 live births. Therefore, it can be assumed that the incidence of NLE is at least 1 per 12,500 live births.

Abstract
Neonatal lupus is an uncommon autoimmune disease manifested primarily by cutaneous lupus lesions and/or congenital heart block. Maternal autoantibodies of the Ro/La family are present in virtually every case, although only approximately 1% of women who have these autoantibodies will have a baby with neonatal lupus. The cutaneous lesions of neonatal lupus may be present at birth, but more often develop within the first few weeks of life. Lesions are most common on the face and scalp, often in a distinctive periorbital distribution. Lesions tend to resolve in a few weeks or months without scarring. The most common cardiac manifestation of neonatal lupus is complete heart block. Heart block typically begins in utero during the second or third trimester. In some cases, heart block begins as first- or second-degree block and then progresses to third-degree block. Complete heart block, once established, appears to be irreversible. In some cases, cardiomyopathy occurs together with complete heart block. Most cases have been noted at birth, but delayed dilated cardiomyopathy has been reported. There have been a few cases of endocardial fibroelastosis occurring in the absence of congenital heart block. Hepatobiliary disease occurs in about 10% of cases. Three types of hepatobiliary disease have been observed: liver failure occurring at birth or in utero, transient conjugated hyperbilirubinemia occurring in infants, or transient transaminase elevations occurring in infants. Hematologic disease, consisting of thrombocytopenia, neutropenia, or anemia, occurs in about 10% of cases. It is common for children with neonatal lupus not to have the full expression of disease, but rather to have only one or two organ systems involved. The diagnosis rests largely on the finding of compatible clinical manifestations plus maternal autoantibodies to Ro and/or La, or, in a few cases, to U1 ribonuclear protein. Although the pathogenesis has not been conclusively established, accumulating evidence, including evidence from animal models, implicates autoantibodies in the pathogenesis of the disease. Therapeutic interventions include attempts at prevention, early intervention, and treatment of well established disease, mainly through the use of systemic corticosteroids. Optimal therapy has yet to be determined. The long-term prognosis for children who have had neonatal lupus is still under investigation, but some children who had neonatal lupus have developed other autoimmune diseases later in childhood. About half of the mothers are asymptomatic at the time of presentation of the child, but some of these women eventually develop symptoms of autoimmune disease.

Abstract
Congenital heart block (CHB) can occur in association with structural heart disease, such as atrioventricular septal defects, left atrial isomerism, and abnormalities of the great arteries, with tumors, such as mesotheliomas, or as an isolated defect. In 1928, Aylward reported the occurrence of CHB in two children whose mother "suffered from Mikulicz's disease." This curious clinical observation was further solidified by the 1970s, with reports of CHB in children whose mothers had autoimmune diseases and that the maternal sera contained antibodies to Ro ribonucleoproteins. It was subsequently reported that many mothers also had antibodies to La. Other abnormalities affecting the skin, liver, and blood elements were associated with anti-Ro/La antibodies in the maternal and fetal circulation, and are now grouped under the heading of neonatal lupus syndromes. Neonatal lupus was termed because the cutaneous lesions of the neonate resembled those seen in systemic lupus erythematosus.

Abstract
OBJECTIVES Neonatal lupus erythematosus (NLE) is associated with maternal anti-Ro/La autoantibodies. It is characterized by heart block and/or cutaneous skin lesions, and occasionally liver disease. This study was performed to determine whether idiopathic neonatal cholestasis (INC) represents NLE without its cardiac or cutaneous findings. METHODS Sera were obtained for autoantibody analysis from mothers of children with INC (N = 11), biliary atresia (N = 25), other liver disease excluding viral hepatitis (liver disease control subjects, N = 14), and healthy children (normal control subjects [NC], N = 22). RESULTS The characteristic serologic findings of NLE, high titer antibodies to Ro and/or La, were absent in mothers from all groups. An unexpected finding was the prevalence of autoantibodies in mothers of infants with liver disease of any type. The frequency of maternal antinuclear antibodies at > or = 1:120 dilution was greater than the estimated frequency in the general population (22% vs. 9%, P = 0.044). The frequency of maternal low titer autoantibodies to 52 kD Ro detected by ELISA was significantly greater than in the NC group (31% vs. 5%, P = 0.014). CONCLUSIONS The majority of cases of INC do not represent NLE. The frequent presence of autoantibodies in mothers of infants in all neonatal liver disease groups raises the possibility that maternal serologic autoimmunity is associated with neonatal liver disease.

Abstract
OBJECTIVE Neonatal lupus erythematosus (NLE) is characterized by complete congenital heart block (CCHB), cutaneous rash, and laboratory abnormalities in infants born to mothers with autoantibodies directed against SSA/Ro, SSB/La, or both. We carried out a prospective study to determine the incidence of individual NLE features. STUDY DESIGN The study was performed in two centers: Toronto, Canada, and Milano, Italy. Mothers had been referred for the presence of anti-SSA/Ro autoantibodies, regardless of their diagnosis. All the children were seen at least once within the first 6 months of life for clinical evaluation and laboratory testing. The study group consisted of 128 infants born from 124 pregnancies in 112 women with anti-Ro antibodies with or without anti-La antibodies. RESULTS There were two cases of CCHB for an overall percentage of 1.6%. Twenty-one children (16%) developed cutaneous NLE. Laboratory testing showed hematologic abnormalities in 27% of the babies and elevation of liver enzymes in 26%. CONCLUSIONS Mothers with autoimmune diseases and anti-Ro antibodies are at risk of delivering a child with NLE but at a low risk of delivering a child with CCHB. Infants born to mothers with anti-Ro or anti-La antibodies should be monitored for other features of NLE in addition to CCHB.

Abstract
AIM To evaluate the role of antioxidant treatment and liver transplantation in the management of neonatal haemochromatosis. METHODS A retrospective review was performed of eight infants with acute liver failure and raised ferritin levels between 1990 and 1998. From 1994, treatment with an antioxidant cocktail (vitamin E, N-acetylcysteine, selenium, prostaglandin E1, and desferrioxamine) was begun once the diagnosis was suspected. Pathological and other findings were reviewed, and outcome before and after antioxidant treatment was evaluated. RESULTS Median age at presentation was 4 days with median ferritin levels of 4180 micro g/l (range 1650-40 000 micro g/l; normal range 110-503 micro g/l). Three infants presented before 1994. One infant died before liver transplantation from acute liver failure and one from neurological damage after transplantation. The third patient underwent successful transplantation at day 13 and remains well on follow up 8 years later. From 1994, five patients received antioxidant treatment, of whom two responded: both responders started antioxidants earlier (by day 5) than non-responders and had lower peak ferritin levels (< 4200 micro g/l) and a milder phenotype. Treatment was continued until ferritin levels were < 500 micro g/l. Both children remain well with mean follow up of 42 months, with no recurrence of iron overload. One child showed a partial response to treatment and survived long enough for a liver transplant, but died from graft failure after the transplant. Two children did not respond to antioxidant treatment; both had multiorgan failure and were not listed for transplantation. Only three of the eight patients survived (37.5%) over this time period. CONCLUSION Neonatal haemochromatosis can be a fatal disease with > 60% mortality. Early treatment with antioxidant cocktail is beneficial and may be curative in those who present with milder phenotype. Liver transplantation should always be considered at an early stage in non-responders and in children with more severe acute liver failure.

Abstract
Computerized tomography (CT) of the brain was performed in 10 of 11 consecutive infants with neonatal lupus erythematosus (NLE) (five boys and six girls). Ten of the 11 infants had brain neurosonography. Nine of 10 infants had abnormal CT scans. There was diffuse, markedly reduced attenuation of the cerebral white matter in four infants studied in the first week of life, and also in an infant 5 weeks of age. Patchy reduced subcortical white matter attenuation was observed in another 5-week-old infant. Basal ganglia calcifications were present in two infants at 2 months of age, one of whom also had mild ventriculomegaly. A patient with macrocephaly studied at 4 months of age had enlarged ventricles and subarachnoid spaces consistent with benign macrocephaly of infancy. Cerebral ultrasound examination was abnormal in all five infants studied in the first week of life and in one infant at 2 months of age. Findings included subependymal cysts (4), echogenic white matter (3), and echogenic lenticulostriate vessels (3). Apart from one case of macrocephaly, there was no clinical evidence of neurologic disease and the subsequent development of these infants has been normal. Subclinical central nervous system (CNS) disease in NLE is likely to be a transient phenomenon that resolves as maternal antibodies are cleared from the infant's circulation. It is important to be aware of these neuroimaging abnormalities to avoid misdiagnosis of congenital viral infection in a newborn with multisystem NLE. The potential for neurologic sequelae is uncertain.

Abstract
CLINICAL PRESENTATION Congenital heart block (CHB) in the absence of major structural abnormalities is associated with maternal antibodies to Ro (SS-A) and La (SS-B). CHB is most commonly diagnosed between 18 and 24 wk of gestation, and may be first, second or third degree (complete). Mortality approaches approximately 20%, and most surviving children require pacemakers. Affected infants may develop cardiomyopathy. Abnormalities in the skin, liver and blood of neonates are also associated with anti-Ro/La antibodies, and are usually self-limiting; these manifestations and CHB are collectively referred to as neonatal lupus syndromes (NLS). INVESTIGATION OF PATHOGENESIS Recent studies demonstrate that Ro/La ribonucleoproteins appear on the surface of apoptotic fetal cardiocytes and are recognized by their cognate antibodies, promoting an inflammatory response. Mice immunized with Ro/La proteins have offspring with conduction abnormalities. In vitro, human serum and IgG with anti-Ro/La antibodies affect the conducting properties of isolated animal heart tissue. DIAGNOSTIC PROBLEMS If fetal bradycardia is identified, a 2-dimensional and M-mode fetal echocardiographic and Doppler ultrasound should be obtained to determine whether there is an atrial arrhythmia or atrioventricular (AV) block, and to what degree, and whether there are major structural abnormalities of the heart. The mother's serum should be tested by ELISA for anti-Ro and/or anti-La antibodies. THERAPEUTIC OPTIONS To date, only anecdotal and retrospective evidence guides in utero therapy of CHB. A prospective trial is currently underway to evaluate the efficacy of maternal oral dexamethasone in treating newly identified first, second or third degree block. Established third-degree block appears to be irreversible. Dexamethasone and sympathomimetics may be of some benefit in treating hydrops fetalis. In pregnant women with anti-Ro/La antibodies, prophylactic therapy is not indicated but serial echocardiographic analysis is strongly recommended, with emphasis on the mechanical PR interval to identify a reversible block. CONCLUSION CHB occurs in approximately 1-5% of pregnancies in mothers with anti-Ro/La antibodies, independent of the mother's disease status, and in approximately 15-20% of pregnancies following the birth of a child with NLS. Treatment of CHB identified in utero is not established but guidelines are provided. Serial echocardiographic monitoring of high-risk pregnancies, using the mechanical PR interval to identify first degree block, may afford the earliest opportunities for therapeutic intervention.

Abstract
We report a 39-year-old female who presented over 11 years with autoimmune cholangiopathy associated with kaleidoscopic manifestations of systemic lupus erythematosus (SLE), including, arthritis, skin changes, pleuritis, diffuse proliferative glomerulonephritis, lymphadenopathy, splenomegaly, hyperglobulinemia, and major depression. While antimitochondrial antibodies (AMA) were absent, antinuclear (ANA) and anti-DNA antibodies were detected in high titres associated with hypocomplementemia. The patient also had vitamin B12 deficiency and antiphospholipid antibodies. The patient required steroids and repeated courses of cyclophosphamide for the management of lupus nephritis, and ursodeoxycholic acid (ursolite) administration resulted in amelioration of cholestatic laboratory abnormalities. This unusual case report and review of literature illustrate that immune liver disease may be an important clinical manifestation of SLE, especially autoimmune cholangiopathy.

Abstract
OBJECTIVE To extend the information base on the hepatobiliary manifestations of neonatal lupus erythematosus (NLE) with regard to frequency of occurrence, clinical characteristics, and outcome. METHODS Review of records from the Research Registry for Neonatal Lupus. RESULTS Nineteen (9%) of 219 patients who had NLE and were enrolled in a national registry had probable or possible NLE hepatobiliary disease. In 16 cases, hepatobiliary disease occurred in addition to cardiac or cutaneous NLE. In 3 cases, hepatobiliary disease occurred as the sole clinical manifestation of NLE. Three clinical variants of hepatobiliary disease were observed: 1) severe liver failure present during gestation or in the neonatal period, often with the phenotype of neonatal iron storage disease; 2) conjugated hyperbilirubinemia with mild or no elevations of aminotransferases, occurring in the first few weeks of life; and 3) mild elevations of aminotransferases occurring at approximately 2 to 3 months of life. The prognosis for the children in the last 2 categories is excellent. CONCLUSIONS Hepatobiliary disease is a relatively common finding in NLE and can be the sole clinical manifestation of NLE. Clinicians should be aware of the broad range of hepatobiliary disease that may occur in children with NLE.

Abstract
OBJECTIVE To extend the information base on cutaneous manifestations of neonatal lupus erythematosus (NLE) with regard to maternal disease, sex of child, onset, localization, influence of UV light, prognosis, and recurrence rates in subsequent pregnancies. METHODS Review of records from the Research Registry for Neonatal Lupus. RESULTS The cohort includes 47 mothers (83% white) whose sera contain anti-SSA/Ro, anti-SSB/La, and/or anti-U1-ribonucleoprotein antibodies and their 57 infants (20 boys and 37 girls) diagnosed with cutaneous NLE (absent heart disease) between 1981 and 1997. At detection of the child's rash, 13 mothers were asymptomatic, 11 had an undifferentiated autoimmune syndrome (UAS), 9 had systemic lupus erythematosus (SLE), 7 Sjögren's syndrome (SS), 6 SLE/SS, and 1 rheumatoid arthritis/SS; 20 reported photosensitivity. Within 5 years, 7 asymptomatic mothers experienced disease progression: 1 developed photosensitivity, 2 SLE, 3 SS, 1 SLE/SS; in 2 mothers UAS progressed to SLE; and 2 mothers with SS developed SLE. The infant's rash often followed UV light exposure; mean age at detection was 6 weeks, and mean duration was 17 weeks. All had facial involvement (periorbital region most common) followed by the scalp, trunk, extremities, neck, and intertriginous areas. In 37, the rash resolved without sequelae, 43% of which were untreated. A quarter had residual sequelae that included telangiectasia and dyspigmentation. One child developed Hashimoto's thyroiditis, and 2 developed systemic-onset juvenile rheumatoid arthritis. Of 20 subsequent births, 7 children were healthy, 2 had congenital heart block (CHB) only, 4 CHB and skin rash, and 7 skin rash only. CONCLUSIONS Future pregnancies should be monitored by serial echocardiograms, given the substantial risk for heart block. Affected children should be observed for later development of a rheumatic disease.

Abstract
A female, term newborn born to a mother with a history of idiopathic thrombocytopenic purpura and antinuclear antibodies, single-stranded A antibody, and IgM anticardiolipin antibodies presented with immune thrombocytopenia, disseminated intravascular coagulation (DIC), microangiopathic hemolytic anemia, and a characteristic lupus rash in the periorbital areas. She responded to combined treatment with dexamethasone and intravenous immunoglobulin (IVIG). At age 9 months, she was readmitted with severe thrombocytopenia, DIC, and microangiopathic hemolytic anemia. She again responded to IVIG. This suggests that microangiopathic hemolysis can be a presenting symptom in neonatal lupus erythematosus and that reoccurrence of the microangiopathic hemolysis may occur even after the disappearance of lupus antibodies.

Abstract
BACKGROUND Cutaneous neonatal lupus erythematosus (NLE) is an uncommon disease described mainly through isolated case reports. OBJECTIVE Our purpose was to examine the cutaneous spectrum, clinical associations, and course of disease in babies with anti-Ro-positive NLE. METHODS This is a retrospective case series evaluation of newborns with anti-Ro-positive NLE seen at a single ambulatory care university center over a 20-year period. Cases were drawn from a population of 3.2 million. Follow-up was at least 3 years. RESULTS Four boys and 14 girls were included in our evaluation. Distribution of skin lesions in 18 babies was as follows: face, 17; periorbital "owl-eye" or "eye mask" facial rash, 14; scalp, 15; arms and legs, 13; trunk and groin, 6. Crusted lesions were predominant in 3. Photosensitivity was seen in 12, and features of cutis marmorata telangiectasia congenita were observed in 4. In 17 neonatal lupus was not suspected until the dermatology consultation. Noncutaneous manifestations included thrombocytopenia in 4, cholestatic hepatitis in 3, and congenital heart block in 3. Four patients had residual telangiectasia that persisted for 3 or more years but eventually cleared in 2 patients. Three babies had dyspigmentation that spontaneously cleared within 22 months. None had atrophy or scarring. CONCLUSION Periorbital, scalp, and extremity lesions are common in cutaneous NLE. Crusted lesions predominated in male infants. In children selected by cutaneous involvement, thrombocytopenia and hepatic disease were present as frequently as cardiac disease and occurred more frequently in male babies with crusted skin lesions. Children with cutaneous NLE should be evaluated for hematologic and hepatic as well as cardiac involvement.

Abstract
Neonatal lupus is categorized by typical clinical features and the presence of maternal auto-antibodies. Mothers are uncommonly affected with clinical disease. The major clinical manifestations in neonates are cardiac, dermatological and hepatic, with rare instances of haemolytic anaemia and thrombocytopenia. The major morbidity and mortality result from complete congenital heart block. Dermatological manifestations occur mainly over the face and present with plaques of erythema with central atrophy, a mid-facial erythema, atrophy around the eyes and a telangiectatic variety. The long term outcome is usually excellent.

Abstract
Collagen vascular diseases seen in children include systemic, discoid and neonatal lupus, dermatomyositis, scleroderma, juvenile rheumatoid arthritis, and, in rare cases, Sjogren's syndrome. Although these diseases are uncommon in children, when seen, they are associated with significant morbidity. This review describes the clinical features of each condition and provides an overview of treatment options now available. These include numerous systemic treatments which can be used as steroid-sparing agents.

Abstract
This article discusses neonatal lupus erythematosus, which is a disease of the newborn defined by the presence of maternal autoantibodies and characteristic clinical features in the neonatal period. Although the autoantibodies often are not associated with clinical disease in the mother, neonatal lupus erythematosus is likely the result of fetal or neonatal tissue damage caused by maternally transmitted IgG autoantibodies.

Abstract
Congenital heart block is considered to be a model of passively acquired autoimmunity, whereby immune abnormalities in the mother lead to the production of autoantibodies that cross the placenta and presumably injure the otherwise normally developing fetus. The major targets of the maternal immune response are the SSA/Ro and SSB/La ribonucleoproteins. Other neonatal abnormalities affecting the skin, liver, and blood elements have also been reported to be associated with anti-SSA/Ro-SSB/La antibodies in the maternal and fetal circulation and are now grouped along with congenital heart block under the heading of the neonatal lupus syndromes. This review covers the histopathology, SSA/Ro-SSB/La antigen-antibody systems, immunogenetics, clinical manifestations, and diagnosis and management strategies of these syndromes.

Abstract
Cutaneous lupus erythematosus may be related to maternal autoantibody production in the neonatal lupus syndrome, or may occur later in childhood, with or without findings of systemic lupus erythematosus (SLE). In the first section, we will discuss the transient, passively transferred neonatal disease, and in the second, we will discuss the persistent, actively acquired forms of lupus erythematosus in childhood.

Abstract
Systemic Lupus Erythematosus (SLE) of childhood is a complex and challenging disease which can occur at any age. Identification of disease early in it's course and aggressive, appropriate management leads to improved outcome for an individual child. The history of SLE indicates how much progress has been made in the last quarter century. A discussion of the etiopathogenesis of SLE demonstrates the complexity of the syndrome. This is followed by a description of clinical manifestations, including diagnostic criteria, differential diagnosis and suggested methods for eliciting important symptoms to make the diagnosis. Evaluation of specific organs is next reviewed highlighting critical organ manifestations that are significant for future prognosis. Treatment of SLE includes a variety of medications, including non-steroidal anti-inflammatory medications, steroids and immuno-suppressive drugs. Attention to physical activity, stress and nutrition is equally important. Signs and symptoms that indicate disease flare or infection are described. Lastly, related syndromes are reviewed.

Abstract
Idiopathic neonatal hepatitis (INH) is a syndrome characterized clinically and histologically but there is little information concerning the relationship between the clinical features and histological findings. In the present study, sixty-two patients clinically diagnosed as non-familial INH were histologically classified into four groups according to a provisional definition based on predominant lesions and examination of their clinical features. Patients of cholestasis (n = 23) and giant cell hepatitis (GCH, n = 21) were most frequent (37% and 33%, respectively), and patients of fatty liver (n = 10) and hepatitis (n = 8) were less common (16% and 13%). The GCH group showed a dominance of male, low birthweight, older and breast-fed babies. The cholestasis group demonstrated a dominance of male, low birthweight, younger and bottle-fed babies. The hepatitis group had the highest frequencies of high-grade hepatomegaly and splenomegaly. Fifty six cases completely recovered. Two died of hepatic failure in early infancy and four had chronic liver diseases at the age of 12 months. The fatty liver group had the worst outcome. Histological features in non-familial INH were variable and typical giant cell hepatitis was seen in only one-third of patients. Characteristic clinical features in each histologically classified group may suggest heterogenous etiologies underlying non-familial INH.

Abstract
OBJECTIVES To determine the health of mothers of offspring with complete congenital heart block (CHB) both at the time of delivery of the affected child and in the long-term, and the percentage of mothers and children with CHB who had anti-SSA/Ro and/or SSB/La antibodies. PATIENTS AND METHODS Sixty-four mothers of 64 children with CHB (seen between 1964 and 1993) were identified through the Cardiology database of The Hospital for Sick Children, Toronto, Canada. Medical information from these of children with CHB was evaluated. Data were obtained from the mothers by mailed questionnaire, telephone interview, and/or from the attending physicians. The presence of anti-Ro antibodies and anti-La antibodies were evaluated by ELISA assay. RESULTS The mean age at the time of delivery of the first child with CHB was 28 +/- 6 years. At the time of delivery 42 (66%) mothers were healthy, 2 (3%) had systemic lupus erythematosus (SLE), 2 (3%) had linear scleroderma, 2 (3%) had rheumatoid arthritis; 3 (5%) had a history of rheumatic fever (but were otherwise well), 1 (2%) had Sjogren's syndrome (SS), and 12 (19%) had an undifferentiated autoimmune syndrome (UAS) (arthralgia, myalgia, photosensitivity, skin vasculitis, Raynaud's phenomenon). The mean time to follow-up from deliver to study was 121 +/- 88 months. The mean maternal age at study was 38 +/- 9 years. Three of 12 mothers who initially had a UAS progressed to SLE (average follow-up time of 80 months, median 96), and 2 developed SS (with average follow-up time 140 months, median 132) and 1 went into remission. The mean follow-up time for the other mothers who did not develop an autoimmune disease was 150 +/- 102 months. Thirty-six of the 42 initially healthy mothers remained well. One mother developed SLE; 1 developed hyperthyroidism; 1 developed anky-losing spondylitis; and 3 developed an UAS. The mean follow-up time of the 36 mothers who remained healthy was similar (123 +/- 97 months) to the 6 initial healthy mothers who developed an autoimmune disease (121 +/- 36 months). Anti-Ro and/or anti-La antibodies were positive in 32 of 53 (60%) mothers tested. Fourteen of the 53 mothers were symptomatic at the time of delivery and 39 were asymptomatic. Anti-Ro and/or anti-La antibodies were positive in 12 of 13 mothers tested at the time of delivery. CONCLUSIONS The long-term maternal outcome in our cohort was very good as most of the initially healthy mothers remained well at follow-up. Twenty-five percent of the mothers with a UAS and only 2% of the initially healthy mothers developed SLE. The development of an autoimmune disease in an asymptomatic mother identified by the birth of a child with CHB was less common in our study than in previous studies. However, close follow-up of mothers with UAS is warranted.

Abstract
Neonatal lupus erythematosus (NLE) is an uncommon disease that is manifested by cutaneous lesions, cardiac conduction defects, or both, that appear in utero or shortly after birth. In approximately 95% of patients, anti-Ro antibody (Ro[SS-A]) has been identified and has become the serologic marker for NLE. Since 1987 there have been four reported cases of Ro- and anti-La antibody (La[SS-B])-negative, U1RNP antibody-positive, NLE. Our affected twin, as well as all other infants with U1RNP-positive NLE, had cutaneous lesions similar to those in Ro-positive NLE, although they lacked systemic abnormalities, including cardiac conduction defects. HLA typing of mothers with infants with U1RNP-positive NLE revealed the presence of HLA-DR4, DQw1, or DQw3 phenotypes. Our typing confirms these findings. As with Ro-positive NLE, no distinct HLA associations were demonstrated in the infants. Unlike Ro-positive mothers, all mothers with a U1RNP-positive infant with NLE had connective tissue disease at the time of the diagnosis and had a different spectrum of disease. We describe the clinical, serologic, and immunogenetic findings in the first reported case of U1RNP-positive NLE in dizygotic twins in whom the NLE disease expression was discordant.

Abstract
Neonatal lupus erythematosus (NLE) is an antibody-mediated disorder most commonly associated with autoantibodies to Ro and/or La antigens. There have been five previous reports describing eight NLE patients with anti-U1RNP antibody in the absence of anti-Ro and anti-La autoantibodies. We report two cases of anti-U1RNP antibody-positive NLE, and briefly review the five previous reports. The diagnosis of NLE was based on physical examination and serological studies by ELISA, immunodiffusion, and immunoblotting. By conventional immunodiffusion and ELISA, our cases were negative for anti-Ro and anti-La antibodies, and positive for anti-U1RNP antibody. However, one of the mothers had anti-La antibody detected by immunoblot assay only. All anti-U1RNP antibody-positive infants had classic cutaneous lesions of NLE, but it is of interest that none had congenital heart block (CHB). Although these infants were negative for anti-Ro and anti-La antibodies with immunodiffusion and ELISA techniques, these antibodies might be detectable by immunoblotting, as was the case in one of the mothers.
