OBJECTIVE: Upregulation of type I interferons (IFN-I) is a hallmark of systemic autoimmune diseases like primary Sjögren's syndrome (pSS), systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). Expression of IFN-I is induced by three different receptor families: Toll-like receptors (TLRs), RIG-like receptors (RLRs) and DNA-sensing receptors (DSRs). TANK-binding kinase (TBK1) is an important signaling hub downstream of RLRs and DSRs. TBK1 activates IRF3 and IRF7, leading to IFN-I production and subsequent induction of interferon stimulated genes (ISGs)...

The most common systemic rheumatologic conditions are connective tissue diseases (including rheumatoid arthritis [RA]) followed by spondyloarthropathy. With the advent of biotherapies and imaging biomarkers, development in the imaging of RA and spondyloarthropathies has received substantial attention in the literature. This article details the various musculoskeletal imaging features of the other connective tissue diseases such as scleroderma and progressive systemic sclerosis, systemic lupus erythematosus, Still's disease, dermatomyositis and polymyositis, Sjögren's syndrome, and mixed connective tissue disease...

Autoimmune diseases are sometimes associated with immune-mediated renal diseases and cryoglobulinemia is one of the causes. Cryoglobulinemia and cryoglobulinemic glomerulonephritis associated with primary Sjögren's syndrome are most frequent condition among non-hepatitis C virus-related condition. Its typical renal manifestation shows high amount of proteinuria with microscopic hematuria and renal insufficiency. We describe a case of 72-year-old woman with Hashimoto disease, autoimmune hepatitis, Sjögren's syndrome, and immune-related pancytopenia complicated by cryoglobulinemic glomerulonephritis...

Registry data worldwide indicate an overall female predominance for pulmonary arterial hypertension (PAH) of 2-4 over men. Genetic predisposition accounts for only 1-5% of PAH cases, while autoimmune diseases and infections are closely linked to PAH. Idiopathic PAH may include patients with undiagnosed autoimmune diseases based on the relatively high presence of autoantibodies in this group. The two largest PAH registries to date report a sex ratio for autoimmune connective tissue disease-associated PAH of 9:1 female to male, highlighting the need for future studies to analyze subgroup data according to sex...

Sjögren's syndrome (SS) and autoimmune thyroid diseases (AITD) may frequently coexist in clinical practice, resulting in a complex overlapping disorder that represents a particular example of the expression of heterogeneity in patients with autoimmune disorders. Objective of this review was to describe the prevalence of the SS-AITD association in the most recent literature, exploring in particular to what extent the presence of AITD might influence the clinical expression of SS and vice versa . Moreover, we summarized some of the proposed genetic, biologic, and molecular mechanisms implied in the pathogenesis of AITD-SS association...

Salivary glands are responsible for maintaining the health of the oral cavity and are routinely damaged by therapeutic radiation for head and neck cancer as well as by autoimmune diseases such as Sjögren's syndrome. Regenerative approaches based on the reactivation of endogenous stem cells or the transplant of exogenous stem cells hold substantial promise in restoring the structure and function of these organs to improve patient quality of life. However, these approaches have been hampered by a lack of knowledge on the identity of salivary stem cell populations and their regulators...

BACKGROUND: Most cases of chronic urticaria (CU) are idiopathic. Circumstantial evidence suggests that some CU cases have an autoimmune pathogenesis. Previous research indicates that a substantial percentage of patients with CU have an atopic background. OBJECTIVES: This study aims to examine the association between CU, and atopic and autoimmune diseases. METHODS: This population-based retrospective cohort study identified 9,332 patients with CU and 37,328 controls matched for age, sex, and number of dermatological clinic visits from the Taiwan National Health Insurance Research Database for 2004-2009...

OBJECTIVES: Triggering of autoimmunity that leads to rheumatic disease has been suggested to depend on gene-environment interactions occurring in epithelial barriers and associated immune cells. Genetic studies have identified associations of the FAM167A-BLK locus with rheumatoid arthritis, SLE, and Sjögren's syndrome. While BLK (B lymphocyte kinase) has a well-established role in B cells, family with sequence similarity 167 member A (FAM167A) and its gene family remain uncharacterized...

Background: Sjögren's syndrome (SS) is a chronic inflammatory autoimmune disease characterized by lymphocytic infiltration of the exocrine glands, especially the salivary and lacrimal glands. As a result of salivary gland dysfunction, most patients with SS have xerostomia related to a reduced salivary flow rate. In addition to the discomfort due to xerostomia, dry mouth can cause various intraoral manifestations such as refractory stomatitis, ulcer, and atrophic changes in the oral mucosa and tongue, and the patient's quality of life (QoL) is severely impaired...

Introduction: Primary Sjögren's syndrome is the third most common systemic autoimmune rheumatic disease, following rheumatoid arthritis and systemic lupus erythematosus, and results in dryness, fatigue, discomfort and sleep disturbances. Sleep is relatively unexplored in primary Sjögren's syndrome. We investigated the experiences of sleep disturbances from the viewpoint of primary Sjögren's syndrome patients and their partners and explored the acceptability of cognitive behavioural therapy for insomnia...

Interstitial nephritis and immune complex-mediated glomerulonephritis are the two common renal manifestations of primary Sjögren's syndrome (SS). Here, we discuss three cases of primary SS where presenting manifestation was distal renal tubular acidosis. The possibility of an underlying autoimmune disorder should be considered in a patient presenting with distal tubular acidosis or recurrent hypokalemic periodic paralysis as treatment of primary disease improves the outcome of illness.

Immune-Mediated Inflammatory Diseases (IMIDs) is a descriptive term coined for an eclectic group of diseases or conditions that share common inflammatory pathways, and for which there is no definitive etiology. IMIDs affect the elderly most severely, with many older individuals having two or more IMIDs. These diseases include, but are not limited to, type-1 diabetes, obesity, hypertension, chronic pulmonary disease, coronary heart disease, inflammatory bowel disease, and autoimmunity, such as rheumatoid arthritis (RA), Sjőgren's syndrome, systemic lupus erythematosus, psoriasis, psoriatic arthritis, and multiple sclerosis...

Primary Sjögren's syndrome (pSS) is a chronic autoimmune rheumatic disease characterized by inflammation of exocrine glands, mainly salivary and lacrimal glands. In addition, pSS may affect multiple other organs resulting in systemic manifestations. Although the precise etiology of pSS remains elusive, pSS is considered to be a multi-factorial disease, where underlying genetic predisposition, environmental factors and epigenetic mechanisms contribute to disease development. Epigenetic mechanisms, such as DNA methylation, histone modifications and non-coding RNAs, may constitute a dynamic link between genome, environment and phenotypic manifestation by their modulating effects on gene expression...

Objective Salivary gland ultrasound (SGU) is a reliable technique for assessing the salivary glands in patients with primary Sjögren's syndrome (pSS). The aim of this study was to elucidate the relationship between SGU findings and autoimmunity in patients with pSS. Methods Patients with pSS underwent an SGU assessment. The patients were classified into three groups according to their autoimmunity profile: the complete positive group (positive rheumatoid factor, antinuclear antibodies, and anti-Ro/anti-La antibodies), the partial seropositive group (positivity of at least one autoantibody but not all), and the seronegative group...

B-cells play a pivotal role in primary Sjögren's syndrome (pSS) pathogenesis. We aim to (1) evaluate the distribution of B-lymphocyte subpopulations in pSS and Sicca patients, (2) establish cut-off points that discriminate pSS from controls, (3) evaluate the association between memory B-cells and phenotypic features in pSS. We included 57 pSS patients, 68 Sicca and 24 healthy controls. Circulating B-cells were characterized by flow cytometry as naïve and memory subsets and classified from Bm1 to Bm5. Compared to controls, pSS patients had lower percentages (29...

To date, numerous genetic and epigenetic studies have been performed and provided a crucial step forward in our understanding of the pathogenesis of rheumatic diseases. However, most of the recent advances in the treatment of rheumatic diseases including biological therapies are not based on or even discrepant from these genetic and epigenetic findings. For example, tumor necrosis factor inhibitors are quite successful in the treatment of rheumatoid arthritis (RA), Behçet's disease (BD), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) but not in that of systemic lupus erythematosus (SLE), systemic sclerosis (SSc), Sjögren's syndrome (SS) and antineutrophil cytoplasmic antibody-associated vasculitis (AAV), conversely, RA shares genetic backgrounds more with SLE, SSc, SS and AAV than BD, AS and PsA...
