Abstract
Autoantibodies are a common mark of autoimmune reaction and their identification in the patients' serum, cerebrospinal fluid, or tissues is generally believed to represent diagnostic or prognostic biomarkers of autoimmune diseases or autoinflammatory conditions. Traditionally, autoantibody testing is an important part of the clinical examination of suspected patients, and in the absence of reliable T cell tests, characterization of autoantibody responses might be suitable in finding causes of specific autoimmune responses, their strength, and sometimes commencement of autoimmune disease. Autoantibodies are also useful for prognostic stratification in clinically diverse groups of patients if checked repeatedly. Antibody discoveries are continuing, with important consequences for verifying autoimmune mechanisms, diagnostic feasibility, and clinical management. Adding newly identified autoantibody-autoantigen pairs to common clinical laboratory panels should help upgrade and harmonize the identification of systemic autoimmune rheumatic disorders and other autoimmune conditions. Herein, we aim to summarize our current knowledge of uncommon and novel autoantibodies in the context of discussing their validation, diagnostic practicability, and clinical relevance. The regular updates within the field are important and well justified.

Abstract
Sjögren disease (SD) is a chronic, autoimmune disease of unknown aetiology with significant impact on quality of life. Although dryness (sicca) of the eyes and mouth are the classically described features, dryness of other mucosal surfaces and systemic manifestations are common. The key management aim should be to empower the individual to manage their condition-conserving, replacing and stimulating secretions; and preventing damage and suppressing systemic disease activity. This guideline builds on and widens the recommendations developed for the first guideline published in 2017. We have included advice on the management of children and adolescents where appropriate to provide a comprehensive guideline for UK-based rheumatology teams.

[PMID: 37523064 DOI: 10.1007/s00415-023-11883-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Revised: 06/24/2023] [Accepted: 07/18/2023] [Indexed: 08/01/2023]
Abstract
OBJECTIVE The aim of this study is to investigate potential risk factors associated with peripheral nervous system lesions in primary Sjögren's syndrome (pSS) through a retrospective analysis of clinical manifestations, examination characteristics, and clinical electrophysiological features. MATERIALS AND METHODS A retrospective case-control study was conducted at Nanfang Hospital, including 108 patients diagnosed with pSS following the criteria revised by the American College of Rheumatology in 2016. The study spanned from January 2015 to October 2020. The patient cohort was divided into two groups, an experimental group (N = 27) consisting of patients with primary Sjögren's syndrome-peripheral nervous system lesions (pSS-PNS), and a control group (N = 81) comprising patients without peripheral neurological impairment, i.e., primary Sjögren's syndrome-non peripheral nervous system lesions (pSS-nPNS). RESULTS The results showed a significant correlation between immunoglobulin G (IgG), α-Fodrin immunoglobulin G (α-FIgG), platelet counts (PLT), dry mouth and peripheral neuropathy of Sjogren's syndrome (p < 0.01). The research also revealed that α-FIgG (OR 2.03; 95% CI 1.14-3.64), IgG (OR 1.23; 95% CI 1.06-1.42), and PLT (OR 1.01; 95% CI 1.00-1.01) were identified as risk factors for the onset of peripheral neuropathy of Sjogren's syndrome, while dry mouth had a negative correlation (OR 0.08; 95% CI 0.02-0.40). Remarkably, the total risk assessment of the independent variables demonstrated a high AUC (95%CI) of 0.923 (0.861-0.986; p < 0.001), indicating an excellent prediction of pSS-PNS occurrence through the ROC analysis. Additionally, high platelet counts and strong positive anti-SSB antibody titer were found to be risk factors for dual motor and sensory nerve damages among pSS-PNS patients. CONCLUSION IgG, α-FIgG, and PLT were identified as independent risk factors for patients with pSS-PNS. The likelihood of peripheral neuropathy appeared to increase in tandem with the elevated levels of above three factors. Interestingly, we found that dry mouth might play a protective role in this context. Our study further noted that both high platelet counts and strong positive anti-SSB antibody titer may be associated with increased risk of both motor and sensory nerve involvement in pSS-PNS patients. These findings have significant implications for both the etiologies and therapeutics of pSS-PNS.

Abstract
Sjögren’s syndrome (SjS) is a heterogeneous systemic disease. The abnormal responses to La/SSB and Ro/SSA of both B-cells and T-cells are implicated as well as others, in the destruction of the epithelium of the exocrine glands, whose tissue characteristically shows a peri-epithelial lymphocytic infiltration that can vary from sicca syndrome to systemic disease and lymphoma. Despite the appearance of new autoantibodies, anti-Ro/SSA is still the only autoantibody included in the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) classification criteria and is used extensively as a traditional biomarker in clinical practice. The study and findings of new autoantibodies in SjS has risen in the previous decade, with a central role given to diagnosis and elucidating new aspects of SjS physiopathology, while raising the opportunity to establish clinical phenotypes with the goal of predicting long-term complications. In this paper, we critically review the classic and the novel autoantibodies in SjS, analyzing the methods employed for detection, the pathogenic role and the wide spectrum of clinical phenotypes.

Abstract
Connective tissue diseases (CTDs) such as systemic lupus erythematosus, systemic sclerosis, myositis, Sjögren's syndrome, and rheumatoid arthritis are systemic diseases which are often associated with a challenge in diagnosis. Autoantibodies (AAbs) can be detected in these diseases and help clinicians in their diagnosis. Actually, pathophysiology of these diseases is associated with the presence of antinuclear antibodies. In the last decades, many new antibodies were discovered, but their implication in pathogenesis of CTDs remains unclear. Furthermore, the classification of these AAbs is nowadays misused, as their targets can be localized outside of the nuclear compartment. Interestingly, in most cases, each antibody is associated with a specific phenotype in CTDs and therefore help in better defining either the disease subtypes or diseases activity and outcome. Because of recent progresses in their detection and in the comprehension of their pathogenesis implication in CTD-associated antibodies, clinicians should pay attention to the presence of these different AAbs to improve patient's management. In this review, we propose to focus on the different phenotypes and features associated with each autoantibody used in clinical practice in those CTDs.

Abstract
The presence of autoantibodies is one of several hallmarks of Sjögren's Syndrome, the detection of serum autoantibodies has a central role in the diagnosis and classification of Sjögren's syndrome. In this review, we will discuss autoantibodies that are helpful in the diagnosis of Sjögren's syndrome. This includes the traditional autoantibodies for disease classification (ANA, Anti-Ro/SSA, Anti-La/SSB, RF), autoantibodies identified from mouse models (Anti-SP1, Anti- PSP, Anti-CA6, and anti-alpha fodrin) and autoantibodies associated with other autoimmune disease (ACA, AMA, and Anti-CCP). We will also review the methods for the detection of autoantibodies and associated challenges for clinical results reporting. The significance of using an autoantibody panel for the diagnosis of SS will be also be reviewed.

Abstract
Purpose To conduct a meta-analysis to evaluate the diagnostic value of anti-muscarinic receptor type 3 (M3R) antibodies in Sjögren syndrome (SS). Methods Two databases, PUBMED and the Cochrane Library, were systematically searched. Approximately 2,000 participants from several studies were included in this research. STATA 11.2 software and Meta-DiSc 1.4 was used to conduct the meta-analysis. Results Eleven studies were included in the meta-analysis. The pooled DOR was 13.00 (95% CI, 6.00–26.00). The sensitivity was 0.43 (95% CI, 0.28–0.58) and the specificity was 0.95 (95%CI, 0.91–0.97). The LR+ and LR- were 7.90 (95% CI, 4.70–13.40), 0.61 (95% CI, 0.46–0.79), respectively. The AUC was 0.89 (95% CI, 0.86–0.92). Conclusion The anti-M3R antibody had high specificity but relatively low sensitivity for the diagnosis of SS.
