Objectives.: Salivary cystatin S is a defence protein mainly produced by submandibular glands and involved in innate oral immunity. This study aimed to verify whether cystatin S was diversely expressed in different disease subsets of primary Sjogren's syndrome (pSS) patients, defined on the basis of salivary flow [unstimulated salivary flow rate (USFR)], minor salivary gland (MSG) focus score and submandibular gland ultrasonography abnormalities. We also evaluated miR-126 and miR-335-5p expression in MSG biopsies to verify whether an aberrant regulation of cystatin S at the glandular level may influence its salivary expression...

The discovery of microRNAs (miRNAs) and their critical role in genetic control opened new avenues in understanding of various biological processes including immune cell lineage commitment, differentiation, proliferation and apoptosis. However, a given miRNA may have hundreds of different mRNA targets and a target might be regulated by multiple miRNAs, thus the characterisation of dysregulated miRNA expression profiles could give a better insight into the development of immunological disturbances in autoimmune diseases...

Primary Sjögren's syndrome (pSS) is a complex and heterogeneous disease. Last year, a great deal of basic and clinical research was carried out in pSS. Following the previous reviews of this publishing series, we will herewith provide a critical digest of the most recent literature on pSS pathogenesis, clinical manifestations and treatment. More specifically, we will focus on the heterogeneity of the disease, on the underlying pathogenetic pathways and on the possible new targeted treatments on the horizon...

Sjögren's syndrome (SS) is a chronic autoimmune disease with broad clinical spectrum, extending from benign exocrinopathy to severe systemic disease and lymphoma development. The glandular and extraglandular dysfunction of SS is associated with lymphocytic infiltrates that invade the epithelial structures of affected organs. The in-depth study of autoimmune lesions in the minor salivary glands (MSG), which are the major target-organ of SS responses, revealed that the lymphocytic infiltrates vary in severity and composition among SS-patients, are full-blown at diagnosis and remain unchanged thereafter...

Fas and its ligand FasL, members of tumor necrosis factor receptor superfamily, have been implicated in the process of cell apoptosis. FasL consists of two forms, membrane FasL (mFasL) and soluble FasL (sFasL). sFasL can be produced by mFasL cleaved by matrix metalloproteinases (MMP) and also reveals a role for binding to Fas which is expressed on cell surface. Although Fas/FasL axis has been implicated in a variety of diseases, its role in Sjogren's syndrome still remains ill defined. In this study, we investigated the potential of sFasL in the pathogenesis of Sjogren's syndrome (SS)...

Primary Sjögren syndrome (pSS)-related interstitial lung disease (ILD) involved about 10-20% of patients. In 20% of cases, ILD can be diagnosed before pSS; anyway, few studies have investigated the frequency of ILD as the first clinically relevant manifestation of pSS, generally referred to retrospective studies. Aim of our prospective study was to describe prevalence, clinical, serological, and instrumental features of non-sicca onset pSS patients with interstitial lung involvement. During a period of 48 months, all consecutive patients diagnosed as pSS were enrolled...

Sjögren syndrome (SS) is characterized by lymphocytic infiltration of exocrine glands, mainly the lacrimal and salivary glands, leading to keratoconjunctivitis sicca and xerostomia. SS is one of the most common autoimmune rheumatic diseases in adults; however, few cases of primary childhood SS with gastrointestinal and liver lesions have been reported in the literature. We report five cases of primary childhood SS with gastrointestinal and liver lesions. Multiple gastric biopsies in four cases revealed atrophic gastritis in the antrum of the stomach or chronic gastritis...

Frontal fibrosing alopecia is a distinctive form of scarring alopecia considered to be a clinical variant of lichen planopilaris. It predominantly occurs in postmenopausal women and has a slowly progressive course. It was first described by Kossard in 1994. Since then the number of reported cases has increased significantly. Coexistence of frontal fibrosing alopecia and autoimmune disorders - such as discoid erythematosus lupus and Sjögren's syndrome - may suggest a common pathogenic background among the diseases...

OBJECTIVE: To estimate the future risk and time trends of venous thromboembolism (VTE) in individuals with newly diagnosed primary Sjögren syndrome (pSS) in the general population. METHODS: Using a population database that includes all residents of British Columbia, Canada, we created a study cohort of all patients with incident SS and up to 10 controls from the general population matched for age, sex, and entry time. We compared incidence rates (IR) of pulmonary embolism (PE), deep vein thrombosis (DVT), and VTE between the 2 groups according to SS disease duration...

Primary biliary cholangitis (PBC) is an autoimmune liver disease characterized by progressive destruction of the intrahepatic bile ducts, leading to cholestasis. PBC is known to have both hepatic and extrahepatic manifestations. Extrahepatic manifestations are seen in up to 73% of patients with PBC, with the most common being Sjogren's syndrome, thyroid dysfunction and systemic sclerosis. It is thought that patients with PBC are at increased risk of developing these extrahepatic manifestations, almost all of which are autoimmune, because patients with autoimmune disease are at higher risk of developing another autoimmune condition...

Patients with primary Sjogren's syndrome (pSS) may go undiagnosed or be misclassified due to the insidious nature and wide spectrum of the disease. The available several classification criteria emphasize glandular findings. We aimed to analyze the efficiency of various classification criteria sets in patients diagnosed on the clinical basis by expert opinion and to compare those pSS patients who fulfilled these criteria with those who did not. This is a multicenter study in which 834 patients from 22 university-based rheumatology clinics are included...

Extranodal mucosa associated lymphoid tissue (ENMALT) marginal zone lymphomas may arise at any site of the body. The most frequent localizations other than gastrointestinal and eye are salivary gland, skin, lung and thyroid. These lymphomas usually arise in a setting of inflammation due to a persistent infection or autoimmune diseases such as Sjogren syndrome in salivary MALT lymphomas and Hashimoto's thryroiditis in thyroid lymphomas. They affect middle-aged patients with a female predominance when lymphoma arises in certain locations...

Large epidemiological studies have shown a consistent increased risk for developing lymphoma in the setting of autoimmune disorders (AID). It is known that this link appears to be stronger for some AID and certain non-Hodgkin lymphoma subtypes e.g. Sjögren's syndrome and extra-nodal marginal zone lymphoma of the salivary gland, and thyroid MALT lymphoma in a background of Hashimoto's thyroiditis. B and T-cell hyperactivity due to chronic antigenic stimulation and the consequent presence of acquired lymphoid tissue seems to play a key role in the pathogenesis of AI-related lymphomas...

Sjögren's syndrome (SS) is a systemic autoimmune disease characterized by the infiltration of lymphocytes into exocrine glands, resulting in the typical sicca symptoms. Unlike adults, primary SS is a very rare condition in childhood, and the risk of malignancy in juvenile SS (JSS) has not been defined. We report the detection of extranodal marginal zone B-cell lymphoma (EMZL) occurring in two children with SS. Fine needle aspiration of the salivary glands (SG) showed nonspecific findings that led to delayed diagnosis of SS...

Sjögren's syndrome (SS) is a chronic and progressive multisystem autoimmune disease typically managed by rheumatologists. Diagnostic delays are common, due in large part to the non-specific and variable nature of SS symptoms and the slow progression of disease. The hallmark characteristics of SS are dry eye and dry mouth, but there are a broad range of other possible symptoms such as joint and muscle pain, skin rashes, chronic dry cough, vaginal dryness, extremity numbness or tingling, and disabling fatigue...

Sjögren's syndrome (SS) and burning mouth syndrome (BMS) typically occur in postmenopausal women. Although these conditions have significantly different etiopathogeneses, patients with SS or BMS often present with analogous oral complaints. The similarities between the two conditions have led to considerable confusion on the part of medical and dental practitioners, and those with BMS or SS often wait years to receive a diagnosis. Therefore, it is imperative for clinicians to understand the characteristic subjective and objective features of each disease and how these can be used to distinguish them...

Sjögren's syndrome (SS) is an autoimmune disease most commonly characterized by ocular and oral dryness. Despite the high prevalence of SS, generation and perpetuation of this disease is still unclear in many aspects. Inflammation, nonetheless, seems to play a central role in this pathology especially in the form of Th-1, Th-2 and Th-17 cytokines release within different aspects, concentrations and connections involved in the maintenance of the syndrome. Moreover, the chronically created pro-inflammatory environment appears to promote glandular atrophy and irreparable architectural modifications...
