The chemokine receptor CXCR3 plays an important role in T cell recruitment in various immune responses and autoimmune diseases. Expression of CXCR3 ligands, including CXCL9, CXCL10, and CXCL11, is elevated in the salivary glands of patients with Sjögren's syndrome (SS). To elucidate whether interaction between CXCR3 and its ligands is required for the development of SS, we administrated an anti-CXCR3 blocking antibody (CXCR3-173) to the non-obese diabetic (NOD) mice, a well-defined model of SS, during the stage prior to disease onset...

BACKGROUND: Patients with sickle cell disease (SCD) present a defective activation of the alternate complement pathway that increases the risk of infection and is thought to predispose to autoimmune disease (AID). However, coexisting AID and SCD is rarely reported, suggesting possible underdiagnosis due to an overlapping of the symptoms. STUDY DESIGN: Among 603 patients with SCD followed between 1999 and June 2016, we retrospectively searched for patients with coexisting SCD and AID...

PURPOSE: Digitization of clinical observation is necessary for assessing the severity of superior limbic keratoconjunctivitis (SLK). This study aimed to use a novel quantitative marker to examine hyperemia in patients with SLK. MATERIALS AND METHODS: We included six eyes of six patients with both dry eye disease and SLK (SLK group) and eight eyes of eight patients with Sjögren syndrome (SS group). We simultaneously obtained the objective finding scores by using slit-lamp examination and calculated the superior hyperemia index (SHI) with an automated conjunctival hyperemia analysis software by using photographs of the anterior segment...

OBJECTIVE: Patients with autoimmune or inflammatory disease (AID) are susceptible to immune-related adverse events (irAEs) when treated with immune check-point inhibitors (ICIs). We decided to analyse the safety and effectiveness of anti-PD-1 antibodies in AID patients and look for an association between the presence of pre-existing AID and the clinical outcome. METHODS: In a prospective study of the REISAMIC registry of grade ≥2 irAEs occurring in ICI-treated patients, we studied the associations between pre-existing AID on one hand and irAE-free survival, overall survival and best objective response rate on the other...

Various systemic inflammatory diseases, such as rheumatoid arthritis (RA), Sjögren's syndrome and systemic lupus erythematosus (SLE) are associated with an increased risk for the development of lymphomas. Studies on patients with RA and Sjögren's syndrome have shown that there is a clear association of the incidence of lymphoma with the severity and activity of the disease and lymphomas in particular are diseases which preferentially occur in immunosuppressed patients; therefore, knowledge of the different lymphoma subtypes, their prognosis and treatment options are important for rheumatologists...

OBJECTIVES: In multiple sclerosis (MS), MRI is a sensitive tool for detecting white matter lesions, but its diagnostic specificity is still suboptimal; ambiguous cases are frequent in clinical practice. Detection of perivenular lesions in the brain (the "central vein sign") improves the pathological specificity of MS diagnosis, but comprehensive evaluation of this MRI biomarker in MS-mimicking inflammatory and/or autoimmune diseases, such as CNS inflammatory vasculopathies, is missing...

Protein quality control depends on the tight regulation of interactions between molecular chaperones and polypeptide substrates. Substrate release from the chaperone Hsp70 is triggered by nucleotide-exchange factors (NEFs) that control folding and degradation fates via poorly understood mechanisms. We found that the armadillo-type NEFs budding yeast Fes1 and its human homolog HspBP1 employ flexible N-terminal release domains (RDs) with substrate-mimicking properties to ensure the efficient release of persistent substrates from Hsp70...

We herein present a case of a 71-year-old woman with primary Sjogren's syndrome (SjS), who developed bilateral pleural effusion and ground glass opacity during treatment with low-dose prednisolone. The pleural effusion and bronchoalveolar lavage fluid revealed elevation of lymphocytes. Thoracoscopic pleural biopsy showed infiltration of lymphocytes with no evidence of other diseases, confirming SjS-related pleuritis. Therefore, we initiated 20 mg prednisolone and pleural effusion was rapidly resolved. Our results indicate that SjS can be rarely complicated with pleuritis...

BACKGROUND Eye and mouth dryness are the most common symptoms reported during ophthalmological and dental examinations, and their frequency increases with age. In connection with population aging and the huge variety of factors and conditions that can induce this condition, it is becoming a serious and growing problem. The purpose of the present study was to determine whether ocular dryness and concomitant xerostomia is associated with particular systemic diseases. MATERIAL AND METHODS We enrolled 642 non-Sjögren patients referred for examination to the ophthalmology or dental clinic of Lublin region, Poland...

A known case of primary Sjogren's syndrome with chronic kidney disease presented with respiratory symptoms and subsequent altered sensorium. Chest imaging suggested cavitating lung lesions in both the lungs. Serum c-ANCA was positive without any upper respiratory tract involvement or active urinary sediments. Treatment with appropriate anti-microbials produced no improvement in the respiratory or neurological parameters. MRI brain revealed tell-tale signs of CNS vascultis. A diagnosis of GPA was made as per European Medical Agency algorithm and the patient was started on immune-suppressants to which there was dramatic response...

Studying Klinefelter's syndrome (male 47,XXY) and triple X (female 4,7XXX), we propose that the number of X chromosomes mediates the female bias of systemic lupus erythematosus (SLE) and Sjögren's syndrome (SS). Our recent paper described SLE and SS patients with extremely rare X chromosome aneuploides in which distal Xp was triplicated, implicating genes lying on the short arm of X1 . Brooks points out that X-linked chronic granulomatosus disease (X-CGD) can also have gene duplication from Xp21.2 to Xp terminus, and some female carriers of X-CDG have a cutaneous lupus-like illness...

Sjögren's syndrome (SS) is a chronic autoimmune disease affecting exocrine glands leading to mouth and eyes dryness. The extent to which epigenetic DNA methylation changes are responsible for an X-chromosome dose effect has yet to be determined. Our objectives were to (i) describe how epigenetic DNA methylation changes could explain an X-chromosome dose effect in SS for women with normal 46,XX genotype and (ii) determine the relevant relationships to this dose effect, between X-linked genes, genes controlling X-chromosome inactivation (XCI) and genes encoding associated transcription factors, all of which are differentially expressed and/or differentially methylated in the salivary glands of SS patients...

Background The involvement of the central nervous system in primary Sjögren syndrome (pSS) remains controversial. Functional magnetic resonance imaging (fMRI) is a relatively new method that can be applied to investigate the heterogeneity of central nervous system (CNS) involvement in pSS patients through regional homogeneity (ReHo) analysis. Purpose To collect data from pSS patients and healthy controls, and use ReHo analysis to elucidate the neurobiological mechanism of CNS involvement in pSS. Material and Methods Fourteen clinically diagnosed pSS patients and 14 age- and gender-matched healthy controls underwent resting-state fMRI...

OBJECTIVE: Dementia is a common neurological disease that substantially affects public health. A previous study revealed that dementia occurs when the body's immune system attacks the cells of the brain, indicating that dementia may be similar to autoimmune rheumatic diseases (ARDs). In the current retrospective cohort study, we focused on middle-aged ARD patients (45 years or older) to investigate the association between ARDs in middle-aged people and dementia by using a nationwide population-based database in Taiwan...
