Background: Complete fetal atrioventricular block (CAVB) is a rare but life-threatening condition, occurring in approximately 1–2% of pregnancies associated with maternal anti-Ro/SSA antibodies. The transplacental migration of anti-Ro/SSA and anti-La/SSB antibodies damages the fetal cardiac system, leading to sustained bradycardia, cardiomyopathy, fetal hydrops, and intrauterine fetal demise. Despite the use of fluorinated corticosteroids or β-agonists, therapeutic efficacy remains limited once a complete block is established. Case Presentation: We present the case of a 35-year-old primigravida with a pregnancy achieved through in vitro fertilization (IVF). At 20 weeks of gestation, she was referred to our emergency unit due to persistent fetal bradycardia. Fetal echocardiography confirmed CAVB with a ventricular rate of 64 bpm. Maternal serologic testing was positive for anti-Ro/SSA and anti-La/SSB antibodies, suggesting an autoimmune etiology. Treatment with oral dexamethasone and salbutamol was initiated, but follow-up echocardiography at 24 weeks showed worsening cardiac status, including reduced ventricular rate of 59 bpm, cardiomegaly, and pericardial effusion. Intrauterine fetal death occurred at 25 weeks of gestation. Management and Outcome: Four months postpartum, the patient underwent a minor salivary gland biopsy. Histopathological evaluation confirmed the diagnosis of primary Sjögren’s syndrome. Conclusions: This case illustrates the severe consequences of autoimmune-mediated CAVB and the limited effectiveness of available treatments once a complete block has developed. It underscores the importance of early fetal rhythm surveillance and targeted maternal autoimmune screening—particularly before assisted reproduction, where structured preconception evaluation offers an opportunity for earlier recognition and risk stratification. Earlier detection may improve counseling and management strategies in future pregnancies. Full article

Background and Objectives: Idiopathic inflammatory myopathies (IIMs) are rare autoimmune diseases with extra-muscular manifestations. A firm association with malignancy, mainly observed in dermatomyositis (DM) is well established and several predictors of malignancy were previously published. However, given the low prevalence of IIMs, large population-based studies are scarce, hindering a comprehensive understanding of site-specific cancer patterns and risk factors. This study aimed to evaluate malignancy patterns and predictors, in a large, diverse cohort of patients with DM and PM. Materials and Methods: This retrospective cohort study used the Clalit Health Services electronic database, including 1557 DM patients and 528 PM patients diagnosed between 2002 and 2018, along with age-, sex-, and residence-matched controls at a 1:5 ratio. The incidence and risk of malignancies were assessed using Cox proportional hazards models, and predictors of solid and hematologic malignancies within the PM/DM cohort were analyzed using adjusted logistic regression. Results: In our cohort, DM was associated with an increased risk of both solid and hematologic malignancies (HR 1.89, 95%CI 1.47–2.41), whereas in PM the association was less pronounced and limited to solid malignancies (HR 1.50, 95%CI 1.06–2.11). In DM, higher risks were observed for breast cancer (HR 1.86) and chronic leukemia (HR 5.02). Across both subtypes, older age at diagnosis, the presence of specific autoantibodies were associated with increased malignancy risk. Significant markers included antiphospholipid antibodies (OR 2.28), lupus anticoagulant (OR 2.29), anti-Mi2 (OR 2.09), any of the antinuclear antibodies (OR 2.37), and individually anti-RNP/Sm (OR 1.70), anti-Ro/La (OR 1.79), anti-Scl-70 (OR 1.60), and anti-DNA (OR 1.97). Conclusions: Our study demonstrates an increased risk of malignancy in both DM and PM, with the relationship being stronger and broader in DM, involving both solid and hematologic cancers. Older age at diagnosis, and a distinct serological profile, particularly antiphospholipid antibodies and various antinuclear antibodies, identify patients at highest risk, warranting heightened clinical vigilance.

Lung involvement is the most common extraglandular manifestation of primary Sjögren’s Disease (pSjD). There is an increasing interest in finding the clinical/serological risk predictors of this feature. A cross-sectional study evaluating anti-SSA/Ro antibodies, anti-SSB/La antibodies, rheumatoid factor, antinuclear antibodies, and the diffusing capacity of the lungs for carbon monoxide (DLCO) in 26 pSjD patients who presented interstitial changes on the chest CT scan was performed. The titres and positivity rates for anti-SSA/Ro (p = 0.02, p = 0.02) and anti-SSB/La antibodies (p = 0.01, p = 0.001) proved to be significantly increased in patients with abnormal DLCO. Anti-SSB/La antibodies’ titres seemed to be the best predictor for decreased DLCO–AUC 0.791 (0.587–0.994), p = 0.016. A close-to-significance decrease was found in the titres (p = 0.07) and positivity rates—p = 0.09 and OR of 0.15 (0.01–1.63)—of anti-SSB/La antibodies in patients with usual interstitial pneumonia (UIP), indicating their possible protective role against UIP. The lymphocytic interstitial pneumonitis (LIP) pattern on lung CT scan was significantly associated with the simultaneous positivity of the four examined serological markers (p = 0.03). The increase in anti-SSB/La antibody positivity rate in patients with LIP patterns was situated close to the significance level (p = 0.09). Quadruple positivity, as well as isolated anti-SSB/La positivity, could be risk factors for developing LIP in pSjD patients. Thus, anti-SSB/La antibodies might represent a marker of lung involvement in pSjD patients. Full article

This case report describes a fetus diagnosed with complete atrioventricular block (CAVB) associated with positive maternal anti-Ro and anti-La antibodies, referred to our fetal cardiology unit at 25 weeks of gestation. The diagnosis of systemic lupus erythematosus (SLE) was established during the investigation of the fetal condition. Oral dexamethasone was initiated and well tolerated, with no adverse effects reported throughout the remainder of the pregnancy. The fetal heart rate (HR) remained above 50 bpm, and, therefore, no beta-sympathomimetic agents were administered. Due to progressive reduction in myocardial contractility and the appearance of early signs of endocardial fibroelastosis, intravenous immunoglobulin (IVIG) therapy was initiated. The patient was hospitalized for the infusion, which was well tolerated without complications, and a second IVIG cycle was administered four weeks later. Significant improvement in ventricular contractility and reduction in fibroelastosis were observed. As reported in the literature, no chronotropic effect was noted, and fetal HR remained stable after treatment. Weekly monitoring of cardiovascular profile score and fetal HR was maintained, with the score consistently remaining at 8 throughout gestation, supporting continued outpatient management. Delivery occurred at 36 weeks and 3 days due to spontaneous preterm labor. A male neonate weighing 3025 g was delivered with Apgar scores of 8 and 9, and an initial heart rate of 84 bpm. Neonatal electrocardiography confirmed persistent CAVB, and the newborn was monitored in the neonatal intensive care unit. At follow-up, the infant remains clinically stable and has not required permanent pacemaker implantation. Full article

Sjögren’s syndrome (SS) is an autoimmune disease characterized by heterogeneous clinical presentation and the presence of various autoantibodies. This study aimed to determine the differences in clinical findings according to antibody positivity in patients with primary Sjögren syndrome (pSS) in the Turkish population. A retrospective study was conducted and 402 patients (378 women and 24 men) with pSS were analyzed. The patients were categorized into three subgroups based on serological tests. These were (1) quadruple seropositivity (positive for anti-Sjögren’s syndrome-related antigen A antibodies (anti-SSA; anti-Ro) and anti-Sjögren’s syndrome-related antigen B antibodies (anti-SSB; anti-La), rheumatoid factor (RF), and antinuclear antibody (ANA); (2) double seropositivity (positive for ANA and anti-SSA/Ro antibodies); and (3) quadruple seronegativity (negative for ANA, RF, anti-SSA/Ro and anti-SSB/La antibodies). The number of quadruple-seropositive patients was 72 (18.6%), double-seropositive 174 (43.2%), and quadruple-seronegative was 85 (21.1%). The age at diagnosis of quadruple-seropositive pSS was 42.4 ± 10.8, which was significantly younger than that of patients with double-seropositive and quadruple-seronegative pSS (p = 0.021, p = 0.112). In terms of organ involvement, salivary gland enlargement, arthralgia, arthritis, Raynaud’s phenomenon, lymphadenopathy, cutaneous vasculitis, interstitial lung disease, neurological involvement, autoimmune thyroiditis, renal interstitial disease, anemia, leukopenia, hypergammaglobulinemia, and hypocomplementemia were more common in quadruple-seropositive patients with pSS than in quadruple-seronegative patients (p < 0.0001). The results of this study confirmed the strong impact of immunological markers on the pSS phenotype at the time of diagnosis. Immunological patterns play a central role in the phenotypic expression of the disease, even during the initial diagnostic phase, and can guide physicians in designing personalized treatment plans for patients with pSS.

Objectives: The association between anti-Ro/SSA antibodies and the appearance of cardiac rhythm disorders in adults is discussed. We aim to study this relationship, together with active treatments and comorbidities, and its impact on daily clinical practice in adults with systemic autoimmune diseases (SADs). Methods: This cross-sectional single-center study was conducted in a tertiary hospital between January 2021 and March 2022. A sample of adult patients followed up in the SAD Unit with a diagnosis of a SAD and previously tested for anti-Ro/SSA and anti-La/SSB were recruited. All of them underwent a 12-lead electrocardiogram. Results: 167 patients were included. 90 (53.9%) were positive for anti-Ro60, 101 (60.5%) for anti-Ro52, and 45 (26.9%) for anti-La/SSB; 52 (31.3%) were triple-negative. 84% were women, and the mean age was 59 years (standard deviation 12.8). The most common SAD was primary Sjögren’s syndrome (34.8%), followed by systemic lupus erythematosus (24.6%) and rheumatoid arthritis (22.8%). A statistically significant relationship was found between anti-Ro52 positivity and cardiac rhythm disorders (relative risk = 2.007 [1.197–3.366]), specifically QTc prolongation (relative risk = 4.248 [1.553–11.615]). Multivariate regressions showed a significant association, with diabetes mellitus being the most related comorbidity. The association between anti-Ro52 antibodies and atrioventricular conduction disorders was not significant. Conclusions: The presence of anti-Ro52 antibodies in adult patients with SADs is associated with an increased risk of QTc prolongation. Electrocardiographic screening of patients with SAD, anti-Ro52 antibodies, and other risk factors, like diabetes mellitus or QT-prolonging drugs, seems advisable. Those with baseline electrocardiogram abnormalities or additional risk factors should undergo electrocardiographic monitoring. Full article

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that predominantly affects women of childbearing age. Pregnancy in SLE patients poses unique challenges due to the potential impact on maternal and fetal outcomes. We provide an overview of the management of SLE during pregnancy, including preconception risk stratification and counseling, treatment, and disease activity monitoring. These assessments are critical to minimize maternal and fetal adverse events in pregnant patients with SLE. Disease flares, preeclampsia, antiphospholipid syndrome complications, and maternal mortality are the major risks for a woman with SLE during gestation. Timely treatment of SLE relapse, differentiation of preeclampsia from lupus nephritis, and tailored management for antiphospholipid syndrome are essential for a successful pregnancy. Fetal outcomes include neonatal lupus (NL), preterm birth, cesarean delivery, fetal growth restriction (FGR), and small-for-gestational-age (SGA) infants. We focused on NL, linked to maternal anti-Ro/SS-A and anti-La/SS-B antibodies, which can lead to various manifestations, particularly cardiac abnormalities, in newborns. While there is a common consensus regarding the preventive effect of hydroxychloroquine, the role of echocardiographic monitoring and fluorinated steroid treatment is still debated. Finally, close postpartum monitoring and counseling for subsequent pregnancies are crucial aspects of care. Full article

Background: The early reliable detection and quantification of autoantibodies play an important role in autoimmune disease diagnosis and in disease-course monitoring. New technologies, such as the multiplexed determination of autoantibodies, have recently been introduced and are being adopted more frequently. The aim of this study was to evaluate the ability of a new microdot array-based multiparametric assay (ZENIT AMiDot CTD panel, A. Menarini Diagnostics, Firenze, Italy) to correctly classify patients with autoimmune rheumatic diseases (ARDs) and compare it to a fluorescence enzyme immunoassay (FEIA) for the detection of anti-ENAs. Methods: The study included 69 consecutive samples from patients with ARDs that were analyzed using two different methods (FEIA and AMiDot) to detect anti-CENP B and six anti-ENA antibodies: anti-Scl-70, anti-SSB/La, anti-Jo-1, anti-U1-RNP, anti-Ro52, and anti-Ro60. The control group sera came from sixty-eight blood donors. Tests were run on the automated slide processor ZENIT FLOW, and then the slides were imaged and analyzed using ZENIT fast. Results: Since the samples were selected for at least one antibody positivity with an ARD diagnosis, we did not calculate clinical sensitivity but only specificity, which was 98.53%, ranging from 90% for anti-SSB/La antibodies to 100% for anti-CENP B ones. Mean agreement among the methods assessed by Cohen’s kappa was 0.816 ± 0.240. Conclusions: The assay demonstrated good clinical performance and may be considered a valuable aid in detecting ARD patients, offering an alternative to methods such as FEIA which are largely in use today.

Objectives—The aim of the present study was to characterize the clinical phenotype of patients with primary Sjögren’s syndrome (pSS) with non-identified antinuclear antibodies (ANA) in comparison with that of patients with pSS with negative ANA, positive typical ANA (anti-Ro/SSA and/or La/SSB) and positive atypical ANA. Methods—We conducted an observational, retrospective monocentric study at the Erasme University Hospital (Brussels, Belgium). Two hundred and thirty-three patients fulfilling the 2002 American–European Consensus Group criteria for pSS were included in this study. The patients were subdivided according to their ANA profile and demographics. The clinical and biological data of each subgroup were compared. Moreover, the relationships between these data and the ANA profiles were determined by multiple correspondence analysis. Results—In our cohort, 42 patients (18%) presented a non-identified ANA-positive profile. No statistically significant difference could be observed between non-identified ANA patients and ANA-negative patients in terms of age and/or ESSDAI score at diagnosis. There were significantly more frequent articular manifestations, positive rheumatoid factor (RF), and the use of corticosteroids in anti-Ro/SSA-positive patients compared to ANA-negative (p ≤ 0.0001) and non-identified ANA-positive patients (p ≤ 0.01). However, a significantly higher proportion of RF positivity and corticosteroid treatment was observed in non-identified ANA-positive patients compared to ANA-negative patients (p < 0.05). Conclusions—For the first time to our knowledge, our study has characterized the clinical phenotype of patients with pSS with non-identified ANA at diagnosis. The non-identified ANA-positive patients featured mostly a clinical phenotype similar to that of the ANA-negative patients. On the other hand, the non-identified ANA-positive patients were mainly distinguished from the ANA-negative patients by a greater proportion of RF positivity and the need for corticosteroid use due to articular involvement.

Background: The fetuses of pregnant women affected by anti-Ro/anti-La antibodies are at risk of developing complete atrioventricular heart block (CAVB) and other potentially life-threatening cardiac affections. CAVB can develop in less than 24 h. Treatment with anti-inflammatory drugs and immunoglobulins (IVIG) can restore the normal rhythm if applied in the transition period. Routine weekly echocardiography, as often recommended, will rarely detect emergent AVB. The surveillance of these pregnancies is controversial. Home-monitoring using a hand-held Doppler is a promising new approach. Methods: To obtain an overview of the current practice in Germany, we developed a web-based survey sent by the DEGUM (German Society of Ultrasound in Medicine) to ultrasound specialists. With the intention to evaluate practicability of home-monitoring, we instructed at-risk pregnant women to use a hand-held Doppler in the vulnerable period between 18 and 26 weeks at our university center. Results: There are trends but no clear consensus on surveillance, prophylaxis, and treatment of anti-Ro/La positive pregnant between specialists in Germany. Currently most experts do not offer home-monitoring but have a positive attitude towards its prospective use. Intensified fetal monitoring using a hand-held Doppler is feasible for pregnant women at risk and does not lead to frequent and unnecessary contact with the center. Conclusion: Evidence-based guidelines are needed to optimize the care of anti-Ro/La-positive pregnant women. Individual risk stratification could help pregnancy care of women at risk and is welcmed by most experts. Hand-held doppler monitoring is accepted by patients and prenatal medicine specialists as an option for intensified monitoring and can be included in an algorithm for surveillance. Full article

Background: Neonatal lupus (NL) is a clinical syndrome that develops in the fetus as a result of maternal autoimmune antibodies. Congenital complete heart block (CHB) is the most common manifestation, while extranodal cardiac manifestations of NL, such as endocardial fibroelastosis (EFE) and myocarditis, are rare but more serious. Less is known about this atrioventricular valve rupture due to valvulitis as a consequence of maternal autoantibodies. We have described a case of cardiac neonatal lupus with an antenatally detected CHB patient who developed mitral and tricuspid valve chordal rupture at 45 days of age. We compared the cardiac histopathology and the fetal cardiac echocardiographic findings of this case with another fetus that was aborted after being antenatally diagnosed with CHB but without valvar rupture. A narrative analysis after a systematic review of the literature regarding atrioventricular valve apparatus rupture due to autoimmune etiology along with maternal characteristics, presentation, treatment, and outcome have been discussed in this article. Objectives: To describe published data on atrioventricular valve rupture in neonatal lupus, including clinical presentation, diagnostic evaluation, management, and outcomes. Methods: We conducted a PRISMA-compliant descriptive systematic examination of case reports that included accounts of lupus during pregnancy or in the newborn period that resulted in an atrioventricular valve rupture. We gathered information on the patient’s demographics, the details of the valve rupture and other comorbidities, the maternal therapy, the clinical course, and the results. We also used a standardized method to evaluate the cases’ quality. A total of 12 cases were investigated, with 11 cases drawn from 10 case reports or case series and 1 from our own experience. Results: Tricuspid valve rupture (50%) is more common than mitral valve rupture (17%). Unlike mitral valve rupture, which occurs postnatally, the timing of tricuspid valve rupture is perinatal. A total of 33% of the patients had concomitant complete heart block, while 75% of the patients had endocardial fibroelastosis on an antenatal ultrasound. Antenatal changes pertaining to endocardial fibroelastosis can be seen as early as 19 weeks of gestation. Patients with both valve ruptures generally have a poor prognosis, especially if they occur at close intervals. Conclusion: Atrioventricular valve rupture in neonatal lupus is rare. A majority of patients with valve rupture had antenatally detected endocardial fibroelastosis in the valvar apparatus. Appropriate and expedited surgical repair of ruptured atrioventricular valves is feasible and has a low mortality risk. Rupture of both atrioventricular valves occurring at close intervals carries a high mortality risk. Full article

A prospectively study of pregnant women with systemic lupus erythematosus (SLE), antiphospholipid syndrome, or non-criteria obstetric antiphospholipid syndrome was conducted to describe the characteristics of women followed in a referral unit and to derive a predictive tool for adverse pregnancy outcome (APO). Demographic characteristics, treatments, SLE activity, and flares were recorded. Laboratory data included a complete blood cell count, protein-to-creatinine urinary ratio (Pr/Cr ratio), complement, anti dsDNA, anti-SSA/Ro, anti-SSB/La, and antiphospholipid antibodies status. A stepwise regression was used to identify baseline characteristics available before pregnancy and during the 1st trimester that were most predictive of APO and to create the predictive model. A total of 217 pregnancies were included. One or more APO occurred in 45 (20.7%) women. A baseline model including non-Caucasian ethnicity (OR 2.78; 95% CI [1.16–6.62]), smoking (OR 4.43; 95% CI [1.74–11.29]), pregestational hypertension (OR 16.13; 95% CI [4.06–64.02]), and pregestational corticosteroids treatment OR 2.98; 95% CI [1.30–6.87]) yielded an AUC of 0.78 (95% CI, [0.70–0.86]). Among first-trimester parameters, only Pr/Cr ratio improved the model fit, but the predictive performance was not significantly improved (AUC of 0.78 vs. 0.81; p = 0.16). Better biomarkers need to be developed to efficiently stratify pregnant women with the most common autoimmune diseases. Full article

Systemic lupus erythematosus is one of the most common autoimmune disorders affecting young women. Pregnant women with lupus are generally at higher risk for certain pregnancy complications than women without comorbidities. Even so, a pregnancy with lupus can be carried to term in optimal conditions if it is properly managed by a doctor. Monitoring is generally recommended six months after the onset of lupus symptoms, and ideally there should be no active lupus symptoms prior to conception. General screening tests should include the anti-phospholipid, anti-Ro and anti-La antibodies. Women who are positive for these antibodies have an increased risk of congenital heart block in the fetus. In addition, pregnant women with lupus have an increased risk of spontaneous abortion, intrauterine fetal growth restriction, pre-term birth, while neonatal lupus syndrome is a major fetal condition. The maternal risks are faced with disease flares, pre-eclampsia and other complications. Treatment options during pregnancy are limited to a few safe medications. For example, prednisone is unlikely to cause fetal malformations, but it increases the risk of diabetes and high blood pressure in the mother. Consequently, a careful multidisciplinary monitoring is essential for optimal results in pregnancy with lupus. Full article

Autoimmune Congenital Heart Block (CHB) is an immune-mediated disease caused by transplacental passage of maternal circulating anti-Ro/SSA and anti-La/SSB antibodies which can bind to fetal cardiac tissue, damaging conduction tissues by inflammation and fibrosis. Approximately 2% of pregnancies with positive anti-Ro antibodies will be complicated by fetal atrioventricular block and the risk of recurrence in subsequent pregnancies is 10 times higher. We report a case of a clinically asymptomatic patient diagnosed with anti-Ro antibodies who had two pregnancies complicated by CHB with different outcomes. Despite preventive treatment with hydroxychloroquine (HCQ) from 6 weeks of pregnancy onward, the fetus developed second to third degree CHB. Dexamethasone was added. The pregnancy evolved to near-term with persistent intermittent CHB. It is not clear how pregnancies with recurrent fetal CHB despite prophylaxis with HCQ should be managed and there is a need for controlled studies to answer the remaining questions in relation to this subject.

Antioxidants are privileged candidates for the development of adjuvants able to improve the efficiency of pharmacological therapies, particularly for chronic inflammatory syndromes. During the last 20 years, anti-TNFα (tumor necrosis factor alpha) monoclonal antibodies infusion has been the biological therapy most frequently administered but there is still large space for improvement in disease remission rates and maintenance. In this context, nutritional bioactive compounds contained in dietary patterns or included as supplements, may act as adjuvants for the induction and maintenance of IBD (inflammatory bowel diseases) remission. To verify this possibility, a single-center preliminary study (SI-CURA, Soluzioni Innovative per la gestione del paziente e il follow up terapeutico della Colite UlceRosA) was designed and carried out to evaluate whether a daily administration of purple corn supplement could improve the response to Infliximab (IFX) infusion of IBD patients with both Crohn’s disease (CD) and ulcerative colitis (UC). A cohort of 47 patients was enrolled in the study. Biological samples were collected before the first and the third IFX infusion. All patients received nutritional guidelines, 27 of them received commercial red fruit tea with low anthocyanins content, while 20 received a purple corn supplement with a high anthocyanin content. Results show that the administration of an antioxidant-enriched purple corn supplement could improve IFX-mediated disease remission in terms of circulating inflammatory markers. Comparison between CD and UC patients revealed that, at this anthocyanin dosage, the purple corn extract administration improved the IFX response in CD but not in UC patients. Our results may pave the way for a new metacentric study of CD patients, recruiting a wider cohort and followed-up over a longer observational time. Full article
