Review
Movement disorders have been known to be associated with a variety of autoimmune diseases, including Sydenham's chorea, pediatric autoimmune neuropsychiatric disorders associated with streptococcus, systemic lupus erythematosus, antiphospholipid syndrome, gluten sensitivity, paraneoplastic and autoimmune encephalopathies. Tremors, dystonia, chorea, ballism, myoclonus, parkinsonism, and ataxia may be the initial and even the only presentation of these autoimmune diseases. Although antibodies directed against various cellular components of the central nervous system have been implicated, the pathogenic mechanisms of these autoimmune movement disorders have not yet been fully elucidated. Clinical recognition of these autoimmune movement disorders is critically important as many improve with immunotherapy or dietary modifications, particularly when diagnosed early. We discuss here the clinical features, pathogenic mechanisms, and treatments of movement disorders associated with autoimmune diseases, based on our own experience and on a systematic review of the literature.

Meta-Analysis
OBJECTIVE
Patients with immune-mediated inflammatory diseases such as rheumatoid arthritis or systemic lupus erythematosus are at increased risk of cardiovascular disease. However, the cardiovascular risk of patients with primary Sjögren's syndrome (SS) remains poorly studied. We aimed to investigate the association between primary SS and cardiovascular morbidity and mortality.
METHODS
We performed a systematic review of articles in Medline and the Cochrane Library and recent abstracts from US and European meetings, searching for reports of randomized controlled studies of cardiovascular morbidity and cardiovascular mortality in primary SS. The relative risk (RR) values for cardiovascular morbidity and mortality associated with primary SS were collected and pooled in a meta-analysis with a random-effects model by using Review Manager (Cochrane collaboration).
RESULTS
The literature search revealed 484 articles and abstracts of interest; 14 studies (67,124 patients with primary SS) were included in the meta-analysis. With primary SS versus control populations, the risk was significantly increased for coronary morbidity (RR 1.34 [95% confidence interval (95% CI) 1.06-1.38]; P = 0.01), cerebrovascular morbidity (RR 1.46 [95% CI 1.43-1.49]; P < 0.00001), heart failure rate (odds ratio 2.54 [95% CI 1.30-4.97]; P < 0.007), and thromboembolic morbidity (RR 1.78 [95% CI 1.41-2.25]; P < 0.00001), with no statistically significant increased risk of cardiovascular mortality (RR 1.48 [95% CI 0.77-2.85]; P = 0.24).
CONCLUSION
This meta-analysis demonstrates that primary SS is associated with increased cardiovascular morbidity, which suggests that these patients should be screened for cardiovascular comorbidities and considered for preventive interventions, in a multidisciplinary approach with cardiologists.

Meta-Analysis Review
OBJECTIVES
The aim of this study is to assess the impact of dryness caused by primary Sjögren's Syndrome (pSS) on smell, taste and sexual function in female patients, and its influence on quality of life.
METHODS
Electronic databases including MEDLINE via Ovid, Web of Science, SCOUPUS, EMBASE and COCHRANE LIBRARY were searched until April 2016. Studies that assessed the function of smell, taste and sexuality in pSS patients, defined by the American European Consensus Group (AECG) criteria. Standardized mean differences (SMD) for individual studies using random-effects meta-analysis were feasible.
RESULTS
Five studies incorporated 378 participants were included in the quantitative synthesis. The impact of pSS vs. healthy controls was: smell SMD -0.78 (95% CI -1.29 to -0.27); taste SMD -1.01 (95% CI -1.54 to -0.49); total sexual function SMD -0.93 (95% CI -1.22 to -0.64); physical and mental component of the quality of life SMD -1.28 (95% CI -1.65 to -0.90) and SMD -0.83 (95% CI -1.27 to -0.40) respectively; anxiety and depression SMD 0.61 (95% CI 0.02, 1.20) and SMD 0.79 (95% CI 0.43 to 1.15), respectively.
CONCLUSION
pSS has a negative impact on smell, taste, sexual function and quality of life in women.

Meta-Analysis
In rheumatoid arthritis and systemic lupus erythematosus, cardiovascular disease is frequently one of the leading causes of mortality or morbidity. Studies have shown that acute systemic inflammation and chronic systemic vasculitis are associated with endothelial dysfunction and atherosclerotic plaque formation, subsequently leading to cardiovascular disease. This meta-analysis aimed to explore the association of subclinical atherosclerosis and arterial stiffness in primary Sjogren's syndrome. A comprehensive search of the MEDLINE and Embase databases was performed from date of inception through August 2017. The inclusion criterion was observational studies evaluating the association between primary Sjogren's syndrome, subclinical atherosclerosis, and arterial stiffness by measuring pulse wave velocity (PWV) and intima-media thickness (IMT). Definitions of PSS and methods to assess PWV and IMT were recorded for each study. Different locations of IMT were evaluated including common carotid, internal carotid, and femoral arteries. The pooled mean difference (MD) of PWV and IMT and 95% confidence interval (CI) were calculated using a random-effect meta-analysis. The between-study heterogeneity of effect size was quantified using the Q statistic and I. Data were extracted from eight observational studies involving 767 subjects. Pooled result demonstrated a significant increase in PWV in patients who have PSS compared with controls (MD = 1.30 m/s; 95% CI 0.48-2.12; p value = 0.002; I = 85%). Patients with PSS also have higher IMT (MD = 0.08 mm; 95% CI 0.04-0.11; p value < 0.01; I = 72%). Our study suggests that PSS is associated with arterial stiffness and subclinical atherosclerosis. Further studies need to be conducted to find the correlation of subclinical atherosclerosis in PSS with the cardiovascular event, the pathophysiological changes of arterial stiffness in PSS, and the benefit of statins, because controlling cardiovascular risk factors or disease activity could potentially help avoid progression of atherosclerosis to overt cardiovascular disease.

Oral Diseases May 2019Systematic review with meta-analysis of interventions for dry mouth symptoms and hyposalivation of Sjögren's syndrome (SS). (Meta-Analysis)
Meta-Analysis
OBJECTIVES
Systematic review with meta-analysis of interventions for dry mouth symptoms and hyposalivation of Sjögren's syndrome (SS).
MATERIALS AND METHODS
We searched MEDLINE, Cochrane Central and EMBASE up to February 2018 for randomized trials of interventions for dry mouth and hyposalivation of SS. The primary outcome was the mean change in xerostomia symptoms. The secondary outcomes included changes in salivary flow and quality of life. We used the Cochrane risk of bias tool for individual studies and the GRADE method to summarize the quality of evidence across studies for the included outcomes.
RESULTS
Thirty-six studies (3,274 patients) were included in the systematic review. Results from the meta-analyses showed high-quality evidence that pilocarpine was superior to placebo in reducing dry mouth symptoms. We found moderate quality of evidence that pilocarpine, rituximab and interferon-alpha were more effective than placebo in increasing salivary flow, with the relevant effect size being large for pilocarpine, and notably smaller for rituximab and interferon-alpha.
CONCLUSION
Clinicians should be very confident in the beneficial effects of pilocarpine upon dry mouth symptoms of SS and moderately confident that pilocarpine, rituximab and interferon-alpha can have beneficial effects upon salivary flow. Adverse events are common. The use of other treatment modalities cannot be supported on the basis of current evidence.

Acta Oto-laryngologica 2023Lymphomas constitute 2% of all salivary gland tumors and are the second most common group of malignancies in the head and neck region. (Review)
Review
BACKGROUND
Lymphomas constitute 2% of all salivary gland tumors and are the second most common group of malignancies in the head and neck region.
OBJECTIVES
In this systematic review, the demographics and characteristics of salivary gland lymphomas are presented.
METHODS
All types of studies that involve data of salivary gland lymphomas between 1990 and 2020 were identified and screened.
RESULTS
A total of 169 articles with 1640 patients were identified. The median age of the patients was 59 years with a range between 10 and 87 years. The anatomic locations of salivary gland lymphomas were distributed with 88% in the parotid glands, 9% in the submandibular glands, 1% in the minor salivary glands, and 0.3% in the sublingual glands. The overall survival at 12 months is high and in line with the outcome of indolent lymphomas in general. The predominant indolent subtypes were extranodal marginal zone lymphomas and follicular lymphomas, whereas the more aggressive subtypes were mainly diffuse large B-cell lymphomas, mantle cell lymphomas, and T-cell lymphomas.
CONCLUSION
In conclusion, lymphomas occur in all salivary glands and mainly in elderly female patients. Sjögren's syndrome is frequently associated. Depending on the anatomical location, the lymphoma subtypes vary in aggressiveness, stage, and prognosis.

Review
OBJECTIVES
To describe the clinical presentation, management and prognosis of patients diagnosed with both primary Sjögren's syndrome (pSS) and anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV).
METHODS
French nation-wide survey completed by a systematic literature review.
RESULTS
This work identified 7 new cases of coexisting pSS and AAV: 2 microscopic polyangiitis (MPA), 2 granulomatosis with polyangiitis (GPA), 2 anti-myeloperoxidase (MPO)-ANCA renal-limited AAV, and 1 eosinophilic granulomatosis with polyangiitis (EGPA). The systematic literature search identified 15 previously published cases. Among the 22 patients, 19 were females. Mean age at diagnosis of AAV was 63.9±9.8years. All individuals with available information experienced at least one extra-glandular manifestation attributable to pSS. p-ANCA with anti-MPO specificity were found in 76.2% (16/21), c-ANCA with anti-PR3 specificity in 14.3% (3/21) and isolated c-ANCA in 13.6% (3/22). Vasculitis involved kidneys (n=13), lungs (n=8), skin (n=6), peripheral nerves (n=5), central nervous system (n=2), small bowel (n=1), muscle (n=1), ear chondritis (n=1) and sinuses (n=1). The mean AAV follow-up was 73.5 (±120.0) months. While on treatment, disease remission occurred in 77.3% of cases, and one death was reported in the first 6months after diagnosis.
CONCLUSION
This work shows that AAV may occur in patients with pSS. These are most commonly p-ANCA associated vasculitis with anti-MPO specificity. AAV may reveal an underlying pSS or arise during its evolution, but did not precede pSS in any of these cases. AAV occurrence appears to be correlated with extra-glandular manifestations of pSS.

Association between type I interferon pathway activation and clinical outcomes in rheumatic and musculoskeletal diseases: a systematic literature review informing EULAR points to consider.
BACKGROUND
Type I interferons (IFN-I) contribute to a broad range of rheumatic and musculoskeletal diseases (RMDs). Compelling evidence suggests that the measurement of IFN-I pathway activation may have clinical value. Although several IFN-I pathway assays have been proposed, the exact clinical applications are unclear. We summarise the evidence on the potential clinical utility of assays measuring IFN-I pathway activation.
METHODS
A systematic literature review was conducted across three databases to evaluate the use of IFN-I assays in diagnosis and monitor disease activity, prognosis, response to treatment and responsiveness to change in several RMDs.
RESULTS
Of 366 screened, 276 studies were selected that reported the use of assays reflecting IFN-I pathway activation for disease diagnosis (n=188), assessment of disease activity (n=122), prognosis (n=20), response to treatment (n=23) and assay responsiveness (n=59). Immunoassays, quantitative PCR (qPCR) and microarrays were reported most frequently, while systemic lupus erythematosus (SLE), rheumatoid arthritis, myositis, systemic sclerosis and primary Sjögren's syndrome were the most studied RMDs. The literature demonstrated significant heterogeneity in techniques, analytical conditions, risk of bias and application in diseases. Inadequate study designs and technical heterogeneity were the main limitations. IFN-I pathway activation was associated with disease activity and flare occurrence in SLE, but their incremental value was uncertain. IFN-I pathway activation may predict response to IFN-I targeting therapies and may predict response to different treatments.
CONCLUSIONS
Evidence indicates potential clinical value of assays measuring IFN-I pathway activation in several RMDs, but assay harmonisation and clinical validation are urged. This review informs the EULAR points to consider for the measurement and reporting of IFN-I pathway assays.

A literature review on new-onset autoimmune connective tissue diseases (ACTDs) following COVID-19 is lacking. We evaluated potential associations between COVID-19 and the development of new-onset ACTDs. The "population" was adults with disease terms for ACTDs, including systemic lupus erythematosus (SLE), Sjogren's syndrome, systemic sclerosis (SSc), idiopathic inflammatory myositis (IIM), anti-synthetase syndrome, mixed CTD and undifferentiated CTD, and "intervention" as COVID-19 and related terms. Databases were searched for English-language articles published until September 2022. We identified 2236 articles with 28 ultimately included. Of the 28 included patients, 64.3% were female, with a mean age was 51.1 years. The USA reported the most cases (9/28). ACTD diagnoses comprised: 11 (39.3%) IIM (including four dermatomyositis); 7 (25%) SLE; four (14.3%) anti-synthetase syndrome; four (14.3%) SSc; two (7.1%) other ACTD (one lupus/MCTD overlap). Of eight, four (14.3%) patients (including that with lupus/MCTD) had lupus nephritis. The average time from COVID-19 to ACTD diagnosis was 23.7 days. A third of patients were admitted to critical care, one for treatment of haemophagocytic lymphohistiocytosis in SLE (14 sessions of plasmapheresis, rituximab and intravenous corticosteroids) and nine due to COVID-19. 80% of patients went into remission of ACTD following treatment, while three (10%) patients died-one due to macrophage activation syndrome with anti-synthetase syndrome and two from unreported causes. Our results suggest a potential association between COVID-19 and new-onset ACTDs, notably in young females, reflecting more comprehensive CTD epidemiology. The most common diagnosis in our cohort was IIM. The aetiology and mechanisms by which ACTDs emerge following COVID-19 remain unknown and require further research.

Frontiers in Immunology 2022To explore the efficacy and safety of Iguratimod intervention in Primary Sjogren's syndrome (pSS). (Meta-Analysis)
Meta-Analysis
OBJECTIVE
To explore the efficacy and safety of Iguratimod intervention in Primary Sjogren's syndrome (pSS).
METHODS
Many databases were searched to collect the RCTs. Three independent reviewers extracted data and assessed the quality of the studies based on the Cochrane Handbook. The statistical analysis was done by RevMan 5.3 and STATA. The quality of evidence was evaluated by GRADE tool.
RESULTS
Twenty-nine RCTs with 2258 participants were included in this review. The meta-analysis shows that: iguratimod experiment group can reduce the ESSPRI score (WMD -1.93 [-2.33, -1.52], P<0.00001), ESSDAI score (WMD -1.39 [-1.81, -0.98], P<0.00001), Schirmer's test (WMD 1.77 [0.85, 2.70], P=0.0002), RF (WMD -5.78 [-7.59, -3.97], P<0.00001), and decrease the ESR level (WMD -7.05 [-9.84, -4.26], P<0.00001). Meanwhile, the summary result showed the addiction of Iguratimod may not increase the adverse events. The adverse events were mainly gastrointestinal discomfort, abnormal liver function, and rash and itching. The quality of evidence of adverse events was moderate. Referring to minimal clinically important difference (MCID), the improvement of ESSPRI is clinically significant, and the improvement of ESSDAI for patients older than 60 years old may be clinically significant.
CONCLUSION
Based on current evidence, iguratimod can effectively reduce ESSPRI score, ESSDAI score, Schirmer's test score and decrease systemic inflammatory response (such as ESR level and RF level) without increasing the probability of adverse events. The recommended course of treatment is at least 12 weeks.
