Abstract
BACKGROUND Mouth dryness increases the risk of some oral health-related conditions. Furthermore, it is unclear if patients with dry mouth engage in appropriate oral health-related behaviours. The study examined oral health, related behaviours, and perceived stress in dry-mouth patients and compared them to matched controls without mouth dryness. METHODS Information about 182 dry-mouth patients and 302 age- and sex-matched subjects was retrieved. Three dry mouth groups: xerostomia, Sicca syndrome and Sjögren's syndrome, were formed based on patient self-reported and objectively assessed symptoms. The World Health Organization's Oral Health for Adults and Perceived Stress Scale (PSS-10) questionnaires inquired about sociodemographic characteristics, oral health-related behaviours, and self-perceived stress. Clinical oral health assessments included: caries experience measured as total numbers of decayed (DS), missing (MS), filled surfaces (FS), number of remaining teeth, erosive tooth wear and extent of periodontal pocketing. Data were analyzed using bivariate and multivariable tests. RESULTS The dry-mouth participants had higher mean (SD) DMFS scores than their matched controls: xerostomia patients vs. controls: 74.6 (34.4) and 66.3 (35.4), Sicca syndrome patients vs. controls: 88.3 (34.0) and 70.1 (33.9), and Sjögren's syndrome patients vs. controls: 95.7 (31.5) and 74 (33.2). In comparison to controls, individuals with Sicca and patients with Sjögren's syndromes had lower mean (SD) number of remaining teeth, 15.9 (10.1) vs. 21.7 (8.4) and 13.8 (10.0) vs. 20.1 (9.2), and a lower mean (SD) extent of periodontal pocketing, 20.7 (28.6) vs. 41.1 (31.0), and 21.2 (24.1) vs. 34.8 (34.2), respectively. Xerostomia, Sicca syndrome and Sjögren's syndrome patients had higher odds of using fluoridated toothpaste; OR 1.8 (95%CI 1.1-2.9), OR 5.6 (95%CI 1.7-18.3) and OR 6.9 (95%CI 2.2-21.3), respectively. Participants with Sjögren's syndrome had lower odds of the last dental visit being within the last year; OR 0.2 (95%CI 0.1-0.8). CONCLUSIONS Dry-mouth patients had higher caries experience and fewer teeth than comparison groups but a lower extent of periodontal pocketing. Even though more participants with dry mouth used fluoridated toothpastes, their oral health-related behaviours were not optimal.

Abstract
This longitudinal study aimed to investigate the risk of subsequent autoimmune disease in patients with post-traumatic stress disorder (PTSD) in Asian population. Between 2002 and 2009, we enrolled 5273 patients with PTSD and 1:4 matched controls from the National Health Insurance Database of Taiwan, and followed up the patients until December 31, 2011, or death. The investigated autoimmune diseases included thyroiditis, lupus, rheumatic arthritis, inflammatory bowel disease, Sjogren's syndrome, dermatomyositis, and polymyositis. The Cox regression model was used to estimate the risk of developing autoimmune diseases, with adjustment for demographics and psychiatric and medical comorbidities. Furthermore, we examined the psychiatric clinics utility of patients with PTSD indicating the severity of PTSD in association with autoimmune diseases. After adjusting for confounders, patients with PTSD had a 2.26-fold higher risk of developing any autoimmune diseases (reported as hazard ratios with 95% confidence intervals: 1.82-2.80) than the controls. For specific autoimmune diseases, patients with PTSD had a 2.70-fold higher risk (1.98-3.68) of thyroiditis, a 2.95-fold higher risk (1.20-7.30) of lupus, and a 6.32-fold higher risk (3.44-11.60) of Sjogren's syndrome. Moreover, the PTSD severity was associated with the risk of autoimmune diseases in a dose-dependent manner. The patient with the highest psychiatric clinics utility was associated with an 8.23-fold higher risk (6.21-10.90) of any autoimmune diseases than the controls. Patients with PTSD had an increased risk of autoimmune diseases, and such risk was associated with the severity of PTSD in a dose-dependent manner. However, the present study did not provide a direct effect between PTSD and autoimmune diseases, but rather an association. Further studies are warranted to examine the underlying pathophysiological mechanisms.

Abstract
Patients with autoimmune inflammatory rheumatic diseases (AIIRDs) are at increased risk for severe infections. Vaccine responses and safety profiles may differ between AIIRD patients and the general population. While patients with autoimmune inflammatory rheumatic diseases (AIIRDs) often experience diminished humoral responses and reduced vaccine efficacy, factors such as the type of immunosuppressant medications used and the specific vaccine employed contribute to these outcomes. Notably, individuals undergoing B cell depletion therapy tend to have poor vaccine immunogenicity. However, despite these considerations, vaccine responses are generally considered clinically sufficient. Ideally, immunosuppressed AIIRD patients should receive vaccinations at least two weeks before commencing immunosuppressive treatment. However, it is common for many patients to already be on immunosuppressants during the immunization process. Vaccination rarely triggers flares in AIIRDs; if flares occur, they are typically mild. Despite the heightened infection risk, including COVID-19, among AIIRD patients with rheumatoid arthritis, systemic lupus erythematosus, sarcoidosis, and other diseases on immunosuppressants, the vaccination rates remain suboptimal. The future directions of vaccination in the era of immunosuppression will likely involve customized vaccines with enhanced adjuvants and alternative delivery methods. By addressing the unique challenges faced by immunosuppressed individuals, we may improve vaccine efficacy, reduce the risk of infections, and ultimately enhance the health outcomes. Additionally, clinical trials to evaluate the safety and efficacy of temporarily discontinuing immunosuppressants during vaccination in various AIIRDs are crucial.

Abstract
Salivary gland epithelial cells (SGEC) are the main targets of the autoimmune reactivity in Sjögren's syndrome (SS). This study aimed to investigate the core proteomic differences between SS and Control- (Ct) -derived SGEC. Proteome analysis of cultured SGEC from five SS patients and four Ct was performed in a label-free quantitation format (LFQ). Electron microscopy was applied for analysis of the mitochondrial ultrastructure of SGEC in minor salivary gland sections from six SS patients and four Ct. Four hundred seventy-four proteins were identified differentially abundant in SS- compared to Ct-SGEC. After proteomic analysis, two distinct protein expression patterns were revealed. Gene ontology (GO) pathway analysis of each protein block revealed that the cluster with highly abundant proteins in SS-SGEC showed enrichment in pathways associated with membrane trafficking, exosome-mediated transport and exocytosis as well as innate immunity related mainly to neutrophil degranulation. In contrast, the low abundance protein cluster in SS-SGEC was enriched for proteins regulating the translational process of proteins related to metabolic pathways associated to mitochondria. Electron microscopy showed decreased total number of mitochondria in SS-SGEC, which appeared elongated and swollen with less and abnormal cristae compared to Ct-SGEC mitochondria. This study defines, for the first time, the core proteomic differences of SGEC between SS and Ct, substantiates the metamorphosis of SGEC into an innate immune cell and reveals that these cells are translationally shifted towards metabolism rewiring. These metabolic alterations are related mainly to mitochondria and are mirrored in situ with heavy morphological changes.

Abstract
In 1933, the Swedish ophthalmologist Hendrik Sjögren was the first to suggest that behind the dryness that several of his patients presented, there could be a systemic disease related to an abnormal immune response. Since then, the term Sjögren's syndrome (SjS) has been used and it has been considered a minor and infrequent disorder compared to other systemic autoimmune diseases (SAD) and, consequently, with little progress both in clinical and therapeutic research. The emergence of new technologies at the end of the 20th century rapidly promoted the development of international projects of great impact and diffusion, which have completely changed this scenario, and in the last 20 years significant progress has been made in understanding the main epidemiological determinants and pathogenic mechanisms to increase the diagnostic accuracy and to design specific and individualized therapeutic strategies. Currently, SjS should be considered one of the most frequent SADs with an undoubtedly systemic phenotype beyond dryness, in which the identification of prognostic factors can allow personalized follow-up and, therefore, early therapeutic interventions that avoid severe, irreversible outcomes.

Abstract
OBJECTIVES The aim of this study was to analyze the risk factors for primary Sjögren's Syndrome (pSS) by conducting a meta-analysis of observational studies. METHODS Four electronic databases were searched from inception to August 2022. The search strategy included medical subject headings (MeSH) and text words. Outcomes were calculated and reported as the odds ratio (OR) and 95% confidence interval (CI). RESULTS Twelve studies consisting of nine case-control and three cohort studies were analyzed. Significant positive relationships between infection, a family history of autoimmune disease in first-degree relatives, negative stressful life events, CGGGG insertion/deletion polymorphisms in the IRF5 gene and the onset of pSS were found, with pooled ORs and 95% CIs of 2.73 (1.93, 3.86), 5.93 (3.34, 10.52), 1.69 (1.27, 2.24) and 2.69 (1.97, 3.66), respectively. In contrast, the results showed that a history of smoking was not associated with the onset of pSS, with a pooled OR and 95% CI of 1.39 (0.76, 2.53). However, a statistically significant negative association between current smoking and pSS was detected, with a pooled OR and 95% CI of 0.4 (0.29, 0.83). CONCLUSIONS Our research indicated that infection, a family history of autoimmune disease in first-degree relatives, negative stressful life events and CGGGG insertion/deletion polymorphisms in the IRF5 gene might be risk factors for pSS. In contrast, our study demonstrated that a history of smoking was not associated with the onset of pSS, whereas current smoking was negatively associated with pSS onset.

Abstract
Diabetic retinopathy (DR) is one of the main causes of blindness. By directly employing mesenchymal stem cells to repair damaged retinal tissues, we aim to study the underlying repair mechanisms. 30 DR patients were included, along with 30 healthy control cases. Western-blot and qRT-PCR
were conducted to measure PI3K/Akt pathway-related genes. The PI3K/Akt antagonist (Rigosertib) was utilized in the induction process of cell differentiation to analyze the effects of PI3K/Akt pathwayspecific proteins and mRNAs. DR patients showed significantly elevated expression of PI3K/Akt
compared to control. With prolongation of induction, the expression of normal epithelial cell-related genes (SpC, SpB, SpA, CK18, KGF and Occludin) was elevated along with upregulated Occludin and KGF, two specific proteins of healthy epithelial cells. Meanwhile, the quantities of Occludin
and KGF in cell culture medium showed a gradual downward trend. In the differentiation of BMSCs towards epithelial cells, addition of PI3K/Akt antagonist Rigosertib was negatively correlated with the expression of several genes (IGF-1, shh, EGF, mTOR, AKT and PI3K) and decreased the quantities
of PI3K/Akt pathway-specific proteins (mTOR, PI3K and AKT). In conclusion, BMSCs can effectively reduce the release of cytokines in DR and promote the repair of damaged diabetic retina, possibly through regulation of PI3K/Akt signaling pathway.

Abstract
Although the pathogenesis of autoimmunity is not fully understood, it is thought to involve genetic, hormonal, immunologic, and environmental factors. Stress has been evaluated as a potential trigger for autoimmunity and disease flares in patients with systemic lupus erythematosus (SLE). The physiologic changes that occur with stress involve numerous catecholamines, hormones, and cytokines that communicate intricately with the immune system. There is some evidence that these systems may be dysregulated in patients with autoimmune disease. Mindfulness-based techniques are practices aimed at mitigating stress response and have been shown to improve quality of life in general population. This review will discuss pathophysiology of chronic stress as it relates to SLE, evidence behind mindfulness-based practices in these patients, and directions for future research.

Abstract
This study assessed the mechanism of regulation of autophagy and inflammation on corneal injury in the model of rats with xerophthalmia. The level of inducer and inhibitor of autophagy in the model of rats with xerophthalmia was detected and cell proliferation was evaluated by MTT assay
together with analysis of colony formation, cell apoptosis and cycle by FCM. The effect of inducer on the corneal injury and inflammation was assessed. The level of autophagy marker LC3 was elevated significantly after treatment with autophagy inducer along with increased cell proliferation
and migration and strengthened sensibility of corneal epithelial cells on corneal injury and inflammation and autophagy rate. In addition, cells in the established model was blocked at G2/M phase. Moreover, autophagy inducer significantly upregulated MMP-10 expression. Furthermore, there was
a target relationship between LC3 and P62. In conclusion, the cell migration, growth and autophagy is induced with autophagy inducer in the model of rats with xerophthalmia, indicating that autophagy inducer might be a brand-new therapeutic target spot for the treatment of xerophthalmia.

Abstract
Sjögren’s syndrome (SjS) is an autoimmune disease characterized by the triad of sicca symptoms, fatigue and pain. This diagnosis is usually made in women at the average age of 60 years. Diagnosis is made when sicca symptoms persist for more than three months, after the exclusion of possible differential diagnoses, and using the ACR/EULAR 2016 classification criteria for SjS. Many organs can be affected in the course of this disease. Xerosis cutis and pruritus are the most common skin manifestations, followed by leukocytoclastic vasculitis and subacute cutaneous lupus erythematosus. In addition, SjS patients often have myoarthralgia and neuropsychiatric symptoms. In the long term, attention must be paid to the increased risk of cardiovascular disease and lymphoma. Due to the multiorgan involvement in SjS patients, interdisciplinary care is required.

Abstract
This study intends to identify the expression profiles of micoRNAs during the recovery of damaged corneal epithelium induced by BMSCs. Differential expressions of miRNA after damage of corneal epithelium stimulated by BMSCs were analyzed based on micro-array and validated by qRT-PCR.
The miRNA’s effect on cell proliferative and apoptotic activity was evaluated through transfection of plasmid with over presentation of miRNA and inhibitor of miRNA. miR-339 was significantly down-regulated in the process of recovery of the damaged corneal epithelium induced by BMSCs.
Importin 13 and EGF expression was reduced after transfection of plasmid with over presentation of miR-339, which were reversed by transfection of the inhibitor of miR-339. Importin 13 was a target of miR-339. The cell proliferation and apoptosis could be restrained by miR-339 through regulation
of the expression of Importin 13. In conclusion, the damaged corneal epithelium induced by BMSCs could be recovered by miR-339 through restraining Importin 13 expression, indicating that it might be a novel target for amelioration of corneal epithelium damage.

Abstract
Dry eye disease (DED) is a common ocular surface disease. Bone marrow mesenchymal stem cells (BMSCs) can differentiate into various cells, and BMSC-derived exosomes (BMSC-exo) is essential to maintaining BMSCs stemness. This study aimed to elucidate the mechanism underlying BMSCexo
in DED. Sixty rats with corneal epithelial injury were treated with BMSCs or BMSC-exo and untreated (each group, n = 20) followed by analysis of the effect of BMSCs and BMSC-exo by evaluating the corneal epithelium damage via measuring the Basso-Beattie-Bresnahan (BBB) score on 1st,
3rd, 7th, 14th, 28th day after treatments. TUNEL staining assessed cell apoptosis, NF200 expression and the number of BrdU-positive cells. There was no significant difference in BBB scores among three groups on the 1st and 3rd day after treatment (p > 0.05) with significant difference
on the 7th, 14th, and 28th day (p <0.05); compared with control group, BMSCs group and combination group had significantly higher BBB score (p < 0.05). The amount of apoptotic cells rose on 3rd and then gradually decreased since 7th day. Moreover, BMSCs and BMSC-exo decreased
the apoptotic index and increased absorbance of NF200 and BrdU-positive rate (p < 0.05). BMSC-exo alleviates corneal epithelial damage in DED and facilitates wound healing possibly through reducing cell apoptosis and increasing retinal neuron-like cell proliferation protein.

Abstract
Until the etiopathogenic factor(s) of autoimmune and autoinflammatory rheumatic disorders will be identified, their classification into entities will continue. However, their similar clinical manifestations, overlapping syndromes, evolution from one entity into another, as well as common autoantibody responses, suggest that autoimmune and autoinflammatory disorders may constitute distinct pathophysiologic processes on the basis of a different genetic background. Prognosis and effective therapeutic regimens are mostly based on the clinico-pathologic severity of the involved tissues or organs and not on the disease label. Autoimmune rheumatic diseases (ARDs) can evolve from one into another disease. Different ARDs can appear in the same individual. Common humoral auto-reactivities appear in different ARDs. Therapy is based on the severity of ARDs expression.

Effects of dehydroepiandrosterone (DHEA) supplementation on cortisol, leptin, adiponectin, and liver enzyme levels: A systematic review and meta-analysis of randomised clinical trials. Int J Clin Pract 2021; 75:e14698. [PMID: 34342920 DOI: 10.1111/ijcp.14698] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 07/17/2021] [Accepted: 08/01/2021] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND AND AIMS Dehydroepiandrosterone (DHEA) supplementation has been investigated in patients with altered cortisol levels and is proposed to ameliorate the metabolic profile related to adipose tissue. However, further research is warranted and evidence is no compelling for liver safety. Hence, we aimed to meta-analyse the effects of DHEA supplementation on circulating levels of cortisol, liver enzymes, and adipokines. METHODS We searched literature published in PubMed, Web of Science, Embase and Scopus, until December 2020. We obtained overall results using the generic inverse of variance method with a random-effects model. RESULTS Through 10 arms, serum cortisol levels decreased significantly after DHEA supplementation [weighted mean difference (WMD): -53.581 nmol/L, 95% confidence interval (CI): -88.2, -18.9, P = .002], without significant heterogeneity (I2 = 36%, P = .117). In contrast, any significance was noted for adiponectin (WMD: -0.045 µg/mL, 95% CI: -0.56, 0.47; P = .865), leptin (WMD: -2.55 µg/mL, 95% CI: -6.2, 1.06; P = .166), aspartate transaminase (AST) (WMD: -3.7 U/L, 95% CI: -10.35, 2.95; P = .276), and alanine aminotransferase (ALT) (WMD: -1.7 U/L, 95% CI: -3.45, 0.06; P = .058). CONCLUSION DHEA supplementation decreased circulating cortisol but did not alter adiponectin, leptin, AST, and ALT levels. Hence, DHEA supplementation could be considered as an adjunct in the management of hypercortisolaemia and is safe for the liver.

Abstract
The interleukin (IL)-1 family member IL-1α is a ubiquitous and pivotal pro-inflammatory cytokine. The IL-1α precursor is constitutively present in nearly all cell types in health, but is released upon necrotic cell death as a bioactive mediator. IL-1α is also expressed by infiltrating myeloid cells within injured tissues. The cytokine binds the IL-1 receptor 1 (IL-1R1), as does IL-1β, and induces the same pro-inflammatory effects. Being a bioactive precursor released upon tissue damage and necrotic cell death, IL-1α is central to the pathogenesis of numerous conditions characterized by organ or tissue inflammation. These include conditions affecting the lung and respiratory tract, dermatoses and inflammatory skin disorders, systemic sclerosis, myocarditis, pericarditis, myocardial infarction, coronary artery disease, inflammatory thrombosis, as well as complex multifactorial conditions such as COVID-19, vasculitis and Kawasaki disease, Behcet's syndrome, Sjogren Syndrome, and cancer. This review illustrates the clinical relevance of IL-1α to the pathogenesis of inflammatory diseases, as well as the rationale for the targeted inhibition of this cytokine for treatment of these conditions. Three biologics are available to reduce the activities of IL-1α; the monoclonal antibody bermekimab, the IL-1 soluble receptor rilonacept, and the IL-1 receptor antagonist anakinra. These advances in mechanistic understanding and therapeutic management make it incumbent on physicians to be aware of IL-1α and of the opportunity for therapeutic inhibition of this cytokine in a broad spectrum of diseases.

Abstract
PURPOSE Previous evidence has shown that psychological stress can trigger the onset of autoimmune disease. This study aimed to investigate the prevalence of stressful life events preceding the onset of symptoms in female primary Sjogren's syndrome (pSS) in China compared to controls and the possible associations of stressful life events with disease activity. PATIENTS AND METHODS This was a hospital-based retrospective case-control study. Sixty-seven consecutive female pSS patients and an equal number of age-matched (± 3 years) healthy controls were recruited for assessment using the related Stressful Life Events Scale. The pSS disease activity was measured by the EULAR Sjogren's syndrome disease activity index. Data were analyzed by SPSS, version 23, using chi-square, univariate logistic regression, multiple logistic regression, and partial correlation. RESULTS A higher number of negative stressful life events before disease onset in pSS patients compared with healthy controls suggest that these play a role in increasing the risk of disease occurrence (OR = 2.59, 95% CI: 1.87-3.58, p < 0.05). The number of positive life events did not differ between the two groups. Both the number and severity of the negative stressful life events were also significantly correlated with disease activity. CONCLUSION Patients with pSS experienced more negative stressful life events in the year preceding the onset of symptoms than controls. Negative stressful life events before symptom onset may be risk factors for pSS and may affect pSS disease activity.

Abstract
The association between Sjögren's syndrome (SS) and protein-losing enteropathy (PLE) was scarcly reported. To analyze the clinical, therapeutic, and outcome characteristics of patients with SS and PLE and also to delineate the potential mechanisms and pathways connecting the gut to SS targeted organ's pathology. Systematic screening was conducted using PubMed/MEDLINE, LILACS, SciELO, Web of Science, and Cochrane, dating 1980 to 2020. SS and PLE were the key words. Eighteen patients with SS and PLE were summarized. The patient's ages ranged between 20 and 88 years, and only 4 were males. Primary SS was observed in most cases. Anti-Ro was detected in 100% of the cases while anti-La was reported in 64% of them. The clinical manifestations were protein loss, edema of the lower limbs, pleural effusion, ascites, facial edema, anasarca, diarrhea, and weight loss. Among these clinical manifestations, edema of the lower limbs was the most severe. Albumin concentration was 0.9-3.4 g/dL which increased to 2.8-4.3 g/dL after treatment. Small bowel biopsy was performed in all of the cases. Concerning the therapy, all the patients received systemic glucocorticoids. All of them improved. The period of onset of improvement ranged from 3 weeks to 36 months (an average of 3 months). The early diagnosis and appropriate therapy of PLE in patients with anti-Ro positive SS and who present edema, anasarca, or hypoalbuminemia is vital for a beneficial outcome. An excellent clinical improvement in all the cases was observed when treated early enough by cortico-therapy, thus preventing patient's deterioration, complications, and reducing morbidity and potential mortality.

Abstract
There is increasing evidence that patients with Coronavirus disease 19 (COVID-19) present with neurological and psychiatric symptoms. Anosmia, hypogeusia, headache, nausea and altered consciousness are commonly described, although there are emerging clinical reports of more serious and specific conditions such as acute cerebrovascular accident, encephalitis and demyelinating disease. Whether these presentations are directly due to viral invasion of the central nervous system (CNS) or caused by indirect mechanisms has yet to be established. Neuropathological examination of brain tissue at autopsy will be essential to establish the neuro-invasive potential of the SARS-CoV-2 virus but, to date, there have been few detailed studies. The pathological changes in the brain probably represent a combination of direct cytopathic effects mediated by SARS-CoV-2 replication or indirect effects due to respiratory failure, injurious cytokine reaction, reduced immune response and cerebrovascular accidents induced by viral infection. Further large-scale molecular and cellular investigations are warranted to clarify the neuropathological correlates of the neurological and psychiatric features seen clinically in COVID-19. In this review, we summarize the current reports of neuropathological examination in COVID-19 patients, in addition to our own experience, and discuss their contribution to the understanding of CNS involvement in this disease.

Abstract
Sjögren’s syndrome (SS) is characterized by xerostomia. We aimed to investigate and compare gene expressions in the labial salivary glands of SS patients with xerostomia SS (sicca) and without xerostomia SS (non-sicca) and of healthy subjects (HS) by means of microarray analysis, and to find genes involved in xerostomia. The study group comprised 11 SS patients (3 SS (sicca) and 8 SS (non-sicca)) and 9 HS. The relative gene expression changes were validated with RT-qPCR in the larger study group. Among the differently expressed genes belonging to the “secretion” ontology group with a fold change >2 and with a p value < 0.05, the Transmembrane P24 Trafficking Protein 10 (TMED10), Protein Disulfide Isomerase Family A Member 4 (PDIA4), Calnexin (CANX), Amyloid Beta Precursor Protein (APP), and Transmembrane BAX Inhibitor Motif Containing 6 (TMBIM6) gene expressions in both SS (sicca) and SS (non-sicca) groups were lower than in HS. Significant correlations were observed between TMED10, PDIA4, and CANX gene expression in SS (sicca) patients compared to the controls. There were no differences between the SS (sicca) and SS (non-sicca) study groups in the expression of the aforementioned genes. Results indicate their role in the endoplasmic reticulum system, their overlapping function and the loss of the APP neuroprotective function in xerostomia. It has a multifactorial origin and can be triggered by disturbances to the various signaling pathways in saliva secretion.

Abstract
Health care has become increasingly fragmented, partly due to advancing medical technology. Patients are often managed by various specialty teams when presenting with symptoms that could be manifestations of different diseases. Approximately one third of them are referred to specialists, at over half for outpatient appointments. Fatigue, pain, depression, dry mouth, headaches, and arthralgia are common complaints and frequently require referral to specialist physicians. Differential diagnoses include fibromyalgia (FM), Sjogren's syndrome (SS), and depression. Evaluations involve various sub-specialist especially physicians like those practicing pain management, rheumatology, and psychiatry. Thresholds for referring vary. Patients sometime feel lost in a 'medical maze'. Disagreement is frequent between specialties regarding management. Each discipline has its own diagnostic and treatment protocols and there is little consensus about shared decision-making. Communication between doctors could improve continuity. There are many differences and similarities in the pathophysiology, symptomatology, diagnosis, and treatment of fibromyalgia, Sjogren's syndrome, and depression. Understanding the associations between fibromyalgia, Sjogren's syndrome and depression should improve clinical outcome via a common holistic approach.

Abstract
Changes to the maternal inflammatory milieu may be a mechanism through which maternal psychosocial stress is transmitted to the fetus. Research investigating a limited number of immune markers may miss important signals. We take a proteomics approach to investigate maternal lifetime stress and 92 biomarkers of immune system status. Participants were enrolled in an urban, dual-site (Boston, n = 301 and New York City, n = 110) pregnancy cohort. We measured maternal lifetime history of stress and trauma using the validated Life Stressor Checklist-Revised (LSC-R). We measured a panel of 92 immune-related proteins in mid-pregnancy serum using proximity extension assay technology. We leveraged the dual-site study design to perform variable selection and inference within the cohort. First, we used LASSO to select immune markers related to maternal stress among Boston mothers. Then, we performed OLS regression to examine associations between maternal stress and LASSO-selected proteins among New York City mothers. LASSO regression selected 19 immune proteins with non-null coefficients (CCL11, CCL23, CD244, CST5, CXCL1, CXCL5, CXCL10, CX3CL1, FGF-23, IL-5, IL-7, IL-10, IL-17C, MCP-2, MMP-1, SLAMF1, ST1A1, TNF-β, and TWEAK). Of these, only the chemotactic cytokine CX3CL1 (i.e. fractalkine) was significantly associated with maternal stress among the validation sample (percent change in LSC-R score per 1% increase in relative fractalkine expression: 0.74, 95% confidence interval: 0.19, 1.28). Expanding research suggests fractalkine plays an important role in many aspects of pregnancy and fetal development and is stress-sensitive. We found that maternal lifetime history of stress and trauma was significantly associated with elevated serum fractalkine levels during pregnancy.

Abstract
INTRODUCTION Mental health problems, such as anxiety, depression, and ineffective family coping, in children with lupus nephritis (LN) can increase the severity and affect the management of the disease, thus affecting the quality of life (QoL) of patients. OBJECTIVE Analyzing the association between levels of depression, anxiety, coping, disease activity on the QoL of pediatric patients with LN. PATIENTS AND METHODS There were 62 pediatric LN participants (16 participants in the induction phase and 46 participants in the maintenance phase). Participants were measured for anxiety, depression, coping, disease activity (systemic lupus erythematosus disease activity index/SLEDAI), and QoL. The measurement results were compared between induction and maintenance groups. Analysis of the association between anxiety, depression, coping, and disease activity with the QoL of children with LN used a multiple logistic regression test with p <0.05. RESULTS The measurement results obtained anxiety (induction = 69.06±3.92 and maintenance = 45.24±10.33; p <0.001), depression (induction = 69.88±3.34 and maintenance = 42.20±9.12; p <0.001), coping (induction = 99.88±12.93 and maintenance = 115.67±7.34; p <0.001), SLEDAI (induction = 15.81±12.58 and maintenance = 0.43±1.26; p <0.001), and QoL (induction = 49.92±12.44 and maintenance = 88.15±8.06; p <0.001).. Anxiety level in the induction group (p = 0.043) and maintenance group (p <0.001; p = 0.032; p = 0.008; p = 0.009). Depression level in the induction group (p = 0.031) and maintenance group (p = 0.024; p = 0.042; p = 0.003). SLEDAI score in the maintenance group (p = 0.003; p = 0.003). Coping in induction group (p = 0.016; p = 0.016) and maintenance group (p = 0.005). CONCLUSION Mental health disorders reduce the QoL of LN children, and the level of QoL in induction phase is lower than maintenance phase.

Abstract
As a severe and highly contagious infectious disease, coronavirus disease 2019 (COVID-19) has caused a global pandemic. Several case reports have demonstrated that the respiratory system is the main target in patients with COVID-19, but the disease is not limited to the respiratory system. Case analysis indicated that the nervous system can be invaded by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and that 36.4% of COVID-19 patients had neurological symptoms. Importantly, the involvement of the CNS may be associated with poor prognosis and disease worsening. Here, we discussed the symptoms and evidence of nervous system involvement (directly and indirectly) caused by SARS-CoV-2 infection and possible mechanisms. CNS symptoms could be a potential indicator of poor prognosis; therefore, the prevention and treatment of CNS symptoms are also crucial for the recovery of COVID-19 patients.

Abstract
Autoimmune diseases represent a complex heterogeneous group of disorders that occur as a results of immune homeostasis dysregulation and loss of self-tolerance. Interestingly, more than 80% of the cases are found among women at reproductive age. Normal pregnancy is associated with remarkable changes in the immune and endocrine signaling required to tolerate and support the development and survival of the placenta and the semi-allogenic fetus in the hostile maternal immune system environment. Gravidity and postpartum represent an extremely challenge period, and likewise the general population, women suffering from autoimmune disorders attempt pregnancy. Effective preconception counseling and subsequent gestation and postpartum follow-up are crucial for improving mother and child outcomes. This comprehensive review provides information about the different pathways modulating autoimmune diseases activity and severity, such as the influence hormones, microbiome, infections, vaccines, among others, as well as updated recommendations were needed, in order to offer those women better medical care and life quality.

EULAR recommendations for the management of Sjögren’s syndrome with topical and systemic therapies. Ann Rheum Dis 2019; 79:3-18.

Abstract
The therapeutic management of Sjögren syndrome (SjS) has not changed substantially in recent decades: treatment decisions remain challenging in clinical practice, without a specific therapeutic target beyond the relief of symptoms as the most important goal. In view of this scenario, the European League Against Rheumatism (EULAR) promoted and supported an international collaborative study (EULAR SS Task Force) aimed at developing the first EULAR evidence and consensus-based recommendations for the management of patients with SjS with topical and systemic medications. The aim was to develop a rational therapeutic approach to SjS patients useful for healthcare professionals, physicians undergoing specialist training, medical students, the pharmaceutical industry and drug regulatory organisations following the 2014 EULAR standardised operating procedures. The Task Force (TF) included specialists in rheumatology, internal medicine, oral health, ophthalmology, gynaecology, dermatology and epidemiology, statisticians, general practitioners, nurses and patient representatives from 30 countries of the 5 continents. Evidence was collected from studies including primary SjS patients fulfilling the 2002/2016 criteria; when no evidence was available, evidence from studies including associated SjS or patients fulfilling previous sets of criteria was considered and extrapolated. The TF endorsed the presentation of general principles for the management of patients with SjS as three overarching, general consensus-based recommendations and 12 specific recommendations that form a logical sequence, starting with the management of the central triplet of symptoms (dryness, fatigue and pain) followed by the management of systemic disease. The recommendations address the use of topical oral (saliva substitutes) and ocular (artificial tear drops, topical non-steroidal anti-inflammatory drugs, topical corticosteroids, topical CyA, serum tear drops) therapies, oral muscarinic agonists (pilocarpine, cevimeline), hydroxychloroquine, oral glucocorticoids, synthetic immunosuppressive agents (cyclophosphamide, azathioprine, methotrexate, leflunomide and mycophenolate), and biological therapies (rituximab, abatacept and belimumab). For each recommendation, levels of evidence (mostly modest) and TF agreement (mostly very high) are provided. The 2019 EULAR recommendations are based on the evidence collected in the last 16 years in the management of primary 2002 SjS patients and on discussions between a large and broadly international TF. The recommendations synthesise current thinking on SjS treatment in a set of overarching principles and recommendations. We hope that the current recommendations will be broadly applied in clinical practice and/or serve as a template for national societies to develop local recommendations.

Ablation of the Chaperone Protein ERdj5 Results in a Sjögren's Syndrome-Like Phenotype in Mice, Consistent With an Upregulated Unfolded Protein Response in Human Patients. Front Immunol 2019; 10:506.

Abstract
Objective: Sjögren's syndrome (SS) is a chronic autoimmune disorder that affects mainly the exocrine glands. Endoplasmic reticulum (ER) stress proteins have been suggested to participate in autoimmune and inflammatory responses, either acting as autoantigens, or by modulating factors of inflammation. The chaperone protein ERdj5 is an ER-resident disulfide reductase, required for the translocation of misfolded proteins during ER-associated protein degradation. In this study we investigated the role of ERdj5 in the salivary glands (SGs), in association with inflammation and autoimmunity. Methods:In situ expression of ERdj5 and XBP1 activation were studied immunohistochemically in minor SG tissues from primary SS patients and non-SS sicca-complaining controls. We used the mouse model of ERdj5 ablation and characterized its features: Histopathological, serological (antinuclear antibodies and cytokine levels), and functional (saliva flow rate). Results: ERdj5 was highly expressed in the minor SGs of SS patients, with stain intensity correlated to inflammatory lesion severity and anti-SSA/Ro positivity. Moreover, SS patients demonstrated higher XBP1 activation within the SGs. Remarkably, ablation of ERdj5 in mice conveyed many of the cardinal features of SS, like spontaneous inflammation in SGs with infiltrating T and B lymphocytes, distinct cytokine signature, excessive cell death, reduced saliva flow, and production of anti-SSA/Ro and anti-SSB/La autoantibodies. Notably, these features were more pronounced in female mice. Conclusions: Our findings suggest a critical connection between the function of the ER chaperone protein ERdj5 and autoimmune inflammatory responses in the SGs and provide evidence for a new, potent animal model of SS.

Abstract
Understanding the formation of Sjogren’s lymphocytic infiltrates could permit earlier diagnosis and better outcomes. We submitted gene transcript abundances in histologically normal rabbit lacrimal glands to principal component analysis. The analysis identified a cluster of transcripts associated with Sjögren’s foci, including messenger RNAs (mRNAs) for C–X–C motif chemokine ligand 13 (CXCL13) and B-cell activating factor (BAFF), which dominated the major principal component. We interpreted the transcript cluster as the signature of a cluster of integrally functioning cells. Pregnancy and dryness increased the likelihood that the cluster would develop to high levels, but responses were subject to high levels of stochasticity. Analyzing microdissected samples from high- and low-cluster-level glands, we found that certain transcripts, including mRNAs for C–C motif chemokine ligand 21 (CCL21), CXCL13, cluster of differentiation 4 (CD4), CD28, CD25, BAFF, and interleukin 18 (IL-18) were significantly more abundant in immune cell clusters (ICs) from the high-cluster-level gland; mRNAs for CCL2, CD25, and IL-1RA were significantly more abundant in acinus-duct axis samples; mRNAs for CCL4, BAFF, IL-6, and IL-10 were more abundant in some acinus-duct samples; cells with high prolactin immunoreactivity were more frequent in interacinar spaces. In conclusion, integrated functional networks comprising Sjögren’s infiltrates, such as ICs, acinar cells, ductal cells, and interacinar cells, can form in histologically normal glands, and it is feasible to detect their molecular signatures.
