    本研究旨在阐明临床特征,系统性红斑狼疮(SLE)患者的预后和耀斑的危险因素。数据来自2011年至2022年在福岛医科大学附属医院新诊断的SLE患者。在研究期间经历过耀斑的患者构成耀斑组,并将其临床特征与无耀斑组进行比较。使用Kaplan-Meier曲线比较两组之间关于几个临床项目的累积无耀斑生存期。在387例SLE患者中,83例新诊断为SLE。他们的平均年龄是37.9岁,29名患者在研究期间出现耀斑。两组的一般特征相似,除了观察期和抗SS-A抗体阳性。关于治疗,在无耀斑组中观察到羟氯喹摄入和联合使用免疫抑制剂的频率显著增加.Kaplan-Meier分析显示,抗SS-A阴性组和联合免疫抑制治疗组的累积无耀斑生存率显着提高。总之,抗SS-A阳性可能是SLE发作的危险因素。反过来,在日常临床实践中,联合免疫抑制治疗可能有益于SLE的治疗。
    This study aimed to elucidate the clinical features, outcomes and risk factors of flares in patients with systemic lupus erythematosus (SLE). Data were collected from patients with newly diagnosed SLE at the Fukushima Medical University Hospital between 2011 and 2022. Patients who experienced a flare during the study period constituted the flare group, and their clinical features were compared with those of the no-flare group. The cumulative flare-free survival regarding several clinical items was compared between the two groups using Kaplan-Meier\'s curves. Among 387 patients with SLE, 83 patients with newly diagnosed SLE were included. Their mean age was 37.9 years, and 29 patients experienced flares during the study period. The general characteristics were similar between the two groups, with the exception of the observation period and anti-SS-A antibody positivity. Regarding therapy, a significantly increased frequency of hydroxychloroquine intake and combination with immunosuppressive agents were observed in the no-flare group. The Kaplan-Meier analysis revealed a significantly higher cumulative flare-free survival in the anti-SS-A negative group and combination immunosuppressive therapy group. In conclusion, anti-SS-A positivity may be a risk factor for SLE flare. In turn, combination immunosuppressive therapy may be beneficial for SLE treatment in daily clinical practice.

    原发性干燥综合征(pSS)属于结缔组织疾病的范畴,其特征在于存在自身抗体,例如抗核抗体(ANA)。然而,根据PSS的分类标准,一些患者可能表现出自身抗体阴性结果。自身抗体阴性的患者可能缺乏结缔组织疾病的典型特征,免疫状态以及器官受累和损伤的程度可能与自身抗体阳性的患者不同。本研究旨在比较自身抗体阳性和阴性患者的临床表型,为临床医生提供疾病分类和治疗选择的见解。pSS患者根据自身抗体的存在和滴度进行分组。随后,比较了这些组之间器官损伤和实验室指标的差异,目的分析自身抗体滴度在评估pSS病情中的价值。(1)ANA阳性患者炎症指标水平升高,包括ESR,IgG水平,唇腺活检病理分级,和整体器官受累,与ANA阴性患者比较(P<0.05)。此外,ANA阳性与多器官损伤发生率较高相关,特别是影响皮肤,粘膜,血液系统(P<0.05)。(2)随着ANA滴度的增加,患者表现出IgG水平升高和器官受累升级(P<0.05).(3)自身抗体阳性组患者(抗核抗体阳性,抗SSA,或抗SSB抗体)的IgG水平高于阴性组(P<0.05)。(4)抗SSA和抗SSB抗体阳性的患者与其他患者相比,炎症指标和IgG水平较高(P<0.05);在器官受累和器官损伤方面没有观察到显著差异.pSS中ANA阳性的患者通常表现出更高水平的炎症和经历多器官损伤的可能性增加。此外,随着ANA滴度的增加,炎症水平和多器官损伤的风险也在上升.此外,抗SSA和抗SSB抗体的存在可能导致炎症水平升高的风险升高,但不会增加器官损伤的风险。
    Primary Sjögren\'s Syndrome (pSS) falls within the category of connective tissue diseases, characterized by the presence of autoantibodies such as antinuclear antibodies (ANA). However, according to the classification criteria for pSS, some patients may exhibit a negative result for autoantibodies. Patients with a negative result for autoantibodies may lack typical features of connective tissue diseases, and the immunological state as well as the extent of organ involvement and damage may differ from those with positive autoantibodies. This study aims to compare the clinical phenotypes of patients with positive and negative autoantibodies, providing insights for disease classification and treatment selection for clinicians. Patients with pSS were grouped based on the presence and titers of their autoantibodies. Subsequently, differences in organ damage and laboratory indicators were compared between these groups, aiming to analyze the value of autoantibody titers in assessing the condition of pSS. (1) Patients with positive ANA exhibited elevated levels of inflammatory indicators, including ESR, IgG levels, lip gland biopsy pathology grade, and overall organ involvement, in comparison with patients with negative ANA (P < 0.05). Furthermore, ANA-positivity correlated with a higher occurrence of multi-organ damage, particularly affecting the skin, mucous membranes, and the hematological system (P < 0.05). (2) As ANA titers increased, patients demonstrated elevated levels of IgG and an escalation in organ involvement (P < 0.05). (3) Patients in the positive autoantibody group (positive for antinuclear antibodies, anti-SSA, or anti-SSB antibodies) had higher IgG levels compared to the negative group (P < 0.05). (4) Patients with positive anti-SSA and anti-SSB antibodies exhibited higher levels of inflammatory indicators and IgG compared to other patients (P < 0.05); however, no significant differences were observed in terms of organ involvement and organ damage. Patients with positive ANA in pSS typically exhibit higher levels of inflammation and an increased likelihood of experiencing multi-organ damage. Furthermore, as the ANA titers increase, both inflammation levels and the risk of multi-organ damage also escalate. Additionally, the presence of anti-SSA and anti-SSB antibodies may contribute to an elevated risk of increased inflammation levels, but does not increase the risk of organ damage.

    系统性红斑狼疮是一种异质性自身免疫性疾病,其中皮肤受累是常见表现。目前认为SLE皮肤受累的光敏性与抗SSA抗体有关。本研究旨在通过血清代谢组学分析,扩大SLE皮肤光敏性分子病理生理学的知识现状。
    23例皮肤受累性SLE(SI)组血清代谢产物,无SI(NSI)组14例,采用UPLC-MS/MS技术对30例健康对照(HC)进行分析,根据SI中抗SSA抗体的表达进行亚组分析。MetaboAnalyst5.0用于富集分析和ROC曲线构建,鉴定与抗SSA抗体相关的皮肤受累SLE的血清代谢标志物。
    我们确定了与SLE光敏性相关的几种代谢物和代谢途径。两种代谢物,SM(d18:1/24:0)和γ-CEHC可以区分抗SSA抗体阳性和阴性SI,AUC为0.829和0.806。这两种光敏化相关物质可能是与抗SSA抗体相关的SLE皮肤受累的潜在标志物。
    这项研究为SI患者的发病机制提供了新的见解,为抗SSA抗体与SLE皮肤光致变应性表现的关系提供了新的分子生物学基础。
    UNASSIGNED: Systemic lupus erythematosus is a heterogeneous autoimmune disease in which skin involvement is a common manifestation. It is currently thought that the photosensitivity of SLE skin involvement is associated with anti-SSA antibodies. This study aimed to expand the current state of knowledge surrounding the molecular pathophysiology of SLE skin photosensitivity through Serum metabolomics analysis.
    UNASSIGNED: The serum metabolites of 23 cases of skin-involved SLE (SI) group, 14 cases of no SI (NSI) group, and 30 cases of healthy controls (HC) were analyzed by using UPLC-MS/MS technology, and subgroup analysis was performed according to the expression of anti-SSA antibodies in SI. MetaboAnalyst 5.0 was used for enrichment analysis and ROC curve construction, identifying serum metabolic markers of skin-involved SLE associated with anti-SSA antibodies.
    UNASSIGNED: We identified several metabolites and metabolic pathways associated with SLE photosensitivity. Two metabolites, SM (d18:1/24:0) and gamma-CEHC can distinguish between anti-SSA antibody-positive and negative SI, with AUC of 0.829 and 0.806. These two photosensitization-related substances may be potential markers of skin involvement in SLE associated with anti-SSA antibody.
    UNASSIGNED: This study provides new insights into the pathogenesis of SI patients, and provides a new molecular biological basis for the association between anti-SSA antibodies and skin photoallergic manifestations of SLE.

    用于抗SSA/Ro60KDa(抗SSA)抗体检测的电泳技术已经逐渐被使用非天然抗原的方法取代。我们旨在根据用于检测抗SSA抗体的方法,比较原发性干燥综合征的患者表型和颗粒外表现的发生。使用非天然抗原(磁珠多重测定;线免疫测定)和天然抗原(反免疫电泳(CIE))的方法,对2008年至2017年根据ACR/EULAR2016标准诊断为pSS的患者的血清进行了抗SSA抗体测试。根据抗SSA抗体状态将人群分为三组:不存在(SSA-),存在于任何方法中,除了CIE(SSA+CIE-),以及在CIE(SSA+CIE+)中的存在。与SSA-(n=80,48.8%)和SSACIE-组(n=14,8.5%)相比,SSACIE组(n=70,42.7%)的患者年轻10岁,并且表现出更多的免疫活性。SSA-和SSA+CIE-组差异不大。仅在CIE中存在抗SSA抗体与pSS的颗粒外表现的发生显着相关(HR=4.45(2.35-8.42))。与CIE相反,使用非天然抗原检测抗SSA抗体的方法无法预测pSS系统表达的发生。
    Electrophoresis-derived techniques for anti-SSA/Ro60 KDa (anti-SSA) antibodies detection have been progressively replaced by methods using non-native antigens. We aimed to compare the patients\' phenotypes and the occurrence of extraglandular manifestations in primary Sjögren\'s syndrome according to the method used to detect anti-SSA antibodies. Sera from patients with a diagnosis of pSS according to ACR/EULAR 2016 criteria between 2008 and 2017 were tested for anti-SSA antibodies using methods with non-native antigens (magnetic bead multiplex assay; line immunoassays) and one with native antigens (counterimmunoelectrophoresis (CIE)). The population was split into three groups according to anti-SSA antibodies status: absence (SSA-), presence in any method except for CIE (SSA+CIE-), and presence in CIE (SSA+CIE+). The patients in the SSA+CIE+ group (n = 70, 42.7%) were ten years younger and presented more immunological activity compared with both the SSA- (n = 80, 48.8%) and SSA+CIE- groups (n = 14, 8.5%). The SSA- and SSA+CIE- groups were poorly distinct. The presence of anti-SSA antibodies solely in CIE was significantly associated with the occurrence of extraglandular manifestations of pSS (HR = 4.45 (2.35-8.42)). Contrary to CIE, methods using non-native antigens to detect anti-SSA antibodies were unable to predict the occurrence of systemic expression of pSS.

    OBJECTIVE: Ultrasonography (US) of salivary glands (SGUS) is a non-invasive tool that allows for diagnosing primary Sjögren\'s syndrome (pSS) or secondary SS (sSS). However, little is known about the prevalence of US findings of SS in other connective tissue diseases (CTDs). The aim of this multicentre observational study was to evaluate, in CTD patients with or without SS, the prevalence of abnormal SGUS findings and the possible association of the findings with clinical or biological phenotypes.
    METHODS: B-Mode SGUS was performed by one operator blinded to clinical data. Each SG was semi-quantitatively rated on a scale from 0-4 according to the Jousse-Joulin score; a score ≥ 2 was considered pathological.
    RESULTS: Data for 194 patients were analyzed (pSS, n = 30; sSS, n = 39; other CTDs, n = 77; controls, n = 48). SGUS findings were abnormal in 80%, 67%, 25% and 2% of patients, respectively. Independent of the underlying disease, age and sex, abnormal SGUS findings were significantly associated with presence of anti-SSA antibodies (p< 0.001), pSS (p< 0.001) and sSS (p< 0.01). Among SS patients, abnormal SGUS findings were associated with the presence of hypergammaglobulinemia, anti-SSA antibodies, objective eye dryness and increased anti-nuclear antibody level, with no difference in EULAR Sjögren\'s Syndrome Disease Activity Index.
    CONCLUSIONS: Abnormal SGUS findings were associated with anti-SSA antibody positivity independent of the underlying disease. In SS patients, abnormal findings were associated with immunologic features and mouth involvement. Among CTD patients, SGUS changes may be associated with a particular immune profile.

    OBJECTIVE: The goal of this study is to determine a link between benign essential blepharospasm and Sjogren\'s syndrome by analyzing the presence of extractable nuclear antigens in this population.
    METHODS: Seventy-two patients with benign essential blepharospasm (BEB) were included in this study. We eliminated patients with hemifacial spasm or blepharospasm secondary to corneal pathology. We collected the values of the Schirmer I test and the results of the anti-SSA and anti-SSB antibodies.
    RESULTS: Our study included 72 patients (144 eyes) whose 62 women (86.1%). Mean age was 74.3 years±10.73. Average Schirmer I test was 3.14mm±4.00mm. Five women (8% of this female population) had positive anti-SSA and SSB antibodies. Their mean age was 65.66 years±13.24 whereas the negative antibody patients had an average age of 75.42±9.27. There was no significant difference between their Schimer I test and the Schirmer I of negative antibody population.
    CONCLUSIONS: This study illustrates the possible association between the presence of Sjögren\'s syndrome and the occurrence of a BEB justifying the search for anti-SSA and anti SSB in blepharospasm patients.

    Anti-SS-A antibodies are often sought for in autoimmune diseases diagnosis. Two different target proteins have actually been identified: Ro52 and Ro60. Clinical and immunological associations seem different depending on anti-Ro52 or anti-Ro60 antibodies presence. However, due to a heterogeneous presentation in the literature, some immunology laboratories in France have stopped providing anti-Ro52 antibody findings. We report here a new hospital study designed to determine the diagnostic utility of the separate detection of anti-Ro52 and anti-Ro60 antibodies. We conducted a retrospective, observational study, including every adult patient with positive antinuclear antibodies (ANA) tested in our immunology laboratory, and associated with anti-Ro52 and/or anti-Ro60 antibodies, between 2011 and 2014. Out of 13032 sera tested for ANA, 399 adults had antibodies to Ro52 and/or Ro60; 81.7% were female, with a mean age of 54.5 ± 17.0 years. Anti-Ro52 antibodies were found in 75.7% of the patients and anti-Ro60 antibodies in 56.9%. Among them, 43.1% were classified in the Ro52 + Ro60- group, 32.6% in the Ro52 + Ro60 + group and 24.3% in the Ro52-Ro60+ group. In the Ro52-Ro60+ group, systemic lupus was the most frequent diagnosis (48.5%), with a possible association with antiphospholipid antibodies (anti-cardiolipin antibodies: OR 2.5 (CI95 [1.0-5.0], p = 0.05) and lupus anticoagulant {OR 3.6 (CI95 [1.10-10.0] p = 0.02)}. In the Ro52+Ro60+, primary Sjögren Syndrome was the most likely (OR 4.2 95% CI [2.1-8.3] p < 10-4), especially in patients Ro52+Ro60+La+. Patients with isolated anti-Ro52 had a wider variety of diseases associated, but among auto-immune diseases they were more prone to inflammatory myositis (OR 10.5 [1.4-81.7], p = 0.02) and inflammatory rheumatism (OR 4.6 [1.6-13.8], p = 0.006) in contrast to systemic lupus (OR 0.2 [0.1-0.3], p < 10-4) or primary Sjögren\'s syndrome (OR 0.1 [0.06-0.2], p < 10-4). We therefore suggest that, when anti-ENA antibodies are prescribed, it should include separate anti-Ro52 and anti-Ro60 antibodies determination. To go even further, we would like to suggest a change in ENA nomenclature to avoid confusion, abandoning the anti-SS-A label in favor of the anti-Ro52/TRIM21 or anti-Ro60 antibody for a clearer designation.

    Fetuses with anti-SSA-mediated complete atrioventricular block (CAVB) are at high risk for perinatal death if they present at <20 weeks of gestation and develop ventricular rates of <55 beats per minute (bpm), cardiac dysfunction, or hydrops [Izmirly et al.: Circulation 2011;124:1927-1935; Jaeggi et al.: J Am Coll Cardiol 2002;39:130-137; Eliasson et al.: Circulation 2011;124:1919-1926]. After our experience with two such fetuses who died with pulseless electrical activity despite being paced within 30 min of birth, we performed an ex utero intrapartum treatment procedure to ventricular pacing on a 36-week CAVB fetus with cardiac dysfunction, mild hydrops, and a ventricular rate of 46 bpm. While still on placental bypass, temporary epicardial ventricular pacing leads were successfully placed; the infant was delivered and made a successful transition to postnatal life. This approach can improve the 11-fold increase in mortality for the preterm fetus with long-standing CAVB, severe bradycardia, and heart failure.

    A causal link has long been described between estrogen and systemic lupus erythematosus activity. Contraceptive and pregnancy management is now common for lupus patients, but pregnancy continues to be associated with higher maternal and fetal mortality/morbidity in systemic lupus erythematosus patients than among the general population. Potential complications include lupus flares, obstetric complications (fetal loss, in utero growth retardation, premature birth) and neonatal lupus syndrome. Association with antiphospholipid antibodies or antiphospholipid syndrome increases the risk of obstetric complications. Anti-SSA and/or anti-SSB antibodies put fetuses at risk for neonatal lupus. Improving the outcome of such pregnancies depends upon optimal systematic planning of pregnancy at a preconception counseling visit coupled with a multidisciplinary approach. Absence of lupus activity, use of appropriate medication during pregnancy based on the patient\'s medical history and risk factors, and regular monitoring constitute the best tools for achieving a favorable outcome in such high-risk pregnancies. The aim of this review is to provide an update on the management of contraception and pregnancy in systemic lupus erythematosus, cutaneous lupus and/or antiphospholipid syndrome in order to reduce the risk of complications and to ensure the best maternal and fetal prognosis.
