Rosanna Dammacco
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease of undefined etiology and with remarkably heterogeneous clinical features. Virtually any organ system can be affected, including the eye. SLE-related eye involvement can be diagnosed in approximately one-third of the patients and is usually indicative of disease activity. An early diagnosis and the adoption of suitable therapeutic measures are necessary to prevent sight-threatening consequences, especially in patients with juvenile SLE. Periocular lesions, such as eyelid involvement and orbital inflammation, are relatively rare and, in case of orbital masses, may require a biopsy control...

OBJECTIVE: There are different imaging techniques to assess the parotid glands (i.e., sialography, salivary gland scintigraphy) in patients with Sjögren syndrome (SS). However, their use is limited by the invasive character or high cost. Ultrasound (US) is gaining interest by rheumatologists as a complementary diagnostic tool for SS. To date, there is an increasing body of evidence supporting its sensitivity in the assessment of salivary glands in SS. The aim of our study was to analyze the potential role of US as a diagnostic and prognostic tool in SS and to discuss existing evidence to support its application use...

A 47 year old man presented with a combination of dry mouth and lightheadedness while standing. His medical background was unremarkable except for cigarette smoking and hyperlipidemia. Sjögren's syndrome was ruled out, and he was referred for evaluation of orthostatic hypotension, which by then included syncopal episodes and injuries. Additional symptoms included dry eyes, constipation, reduced sweating, and erectile dysfunction. After excluding medications and structural cardiac abnormalities as causes of orthostatic hypotension, a clinical autonomic evaluation was performed...

Extranodal marginal zone lymphoma (EMZL), mostly represented by mucosa-associated lymphoid tissue (MALT) type, also referred to as MALT lymphoma, is a clinically heterogeneous entity within the group of low-grade B cell lymphomas that arises in a wide range of different extranodal sites, including the stomach, lung, ocular adnexa, and skin. It represents the third most common non-Hodgkin lymphoma in the Western world, and the median age of occurrence is around 60 years. One characteristic aspect in a subset of EMZL detectable in about 25% of the cases is the presence of specific chromosomal translocations involving the genes MALT1 and BCL10, which lead to activation of the NF-κB signaling pathway...

Autophagy is known to be implicated in the pathogenesis of Sjögren syndrome (SS), but evidences are limited. We aimed to examine the levels of autophagy markers in tear film and conjunctival epithelial cells from SS dry eye patients, and analyze their correlations with clinical features. Patients with SS dry eye exhibited lower Schirmer values, lower tear breakup time, and higher ocular staining scores. In tears, ATG5 and LC3B-II/I levels were significantly higher in SS dry eye. ATG5 and LC3B-II mRNA in the conjunctiva were also elevated in SS dry eye compared with non-SS dry eye...

Between August 2009 and May 2016, 74 patients underwent sialoendoscopic surgery. 32 patients had parotid gland disease and 9 patients had intermittent swelling of the parotid gland and sialoliths were not detected with CT imaging. 4 patients were diagnosed with idiopathic Stensen's duct stenosis. Sialendoscopy directly confirmed Stensen's duct stenosis in 2 patients. However, the sialendoscope was unable to be inserted in the other 2 patients, who had stenosis of the orifice of the Stensen's duct. Balloon expansion of the duct was performed in these 2 patients and a steroid drug was injected into the duct in one patient...

Flammer syndrome (FS) is a term to blanket a cluster of vascular and nonvascular signs and symptoms linked to primary vascular dysregulation (PVD), increased sensitivity to various stimuli (stress, drugs, etc.) and altered sense regulation such as pain, smell and thirst perception. On one hand, disruption of blood barrier and homeostasis of the body are the main targets of vascular irregularity. Inflammation and immune disorders including autoimmunity are considered as a consequence of the abnormal vascular regulation processes...

Primary Sjögren's syndrome is an autoimmune disease characterized by dry eye and dry mouth. We systematically reviewed all the randomized controlled clinical trials published in the last 15 years that included ocular outcomes. We found 22 trials involving 9 topical, 10 oral, 2 intravenous and 1 subcutaneous modalities of treatment. Fluoromethalone eye drops over 8 weeks were more effective than topical cyclosporine in the treatment of dry eye symptoms and signs; similarly, indomethacin eye drops over 1 month were more efficacious than diclofenac eye drops...

Renal involvement in primary Sjogren's syndrome (pSS) varies in severity and prevalence. Although previously felt to be uncommon, kidneys can be involved in up to 25%-30% of pSS patients. Fibrillary glomerulonephritis (FGN) is a rare primary glomerular disease that can occur in association with another autoimmune condition or malignancy. The diagnosis relies on renal biopsy findings of haphazardly arranged fibrils in all glomerular compartments and distinction from other forms of fibrillary glomerulopathies such as renal amyloidosis and immunotactoid glomerulopathy...

Th17 cells play an important physiological role at mucosal barriers, and are involved in inflammatory responses to pathogens. Th17 cells and their signature cytokine IL-17 are also present in salivary gland lesions of primary Sjögren's syndrome (pSS) patients and can be elevated in their peripheral blood. In pSS patients, clear correlations between increased Th17 cell activity and symptoms of the disease have not been found, but Th17 cells may contribute to disease progression, for example by supporting autoreactive B cell responses...

Small fiber neuropathy, which affects the sensory A≏ and C fibers, is now a major diagnostic and therapeutic challenge. Nearly 7% of the general population have chronic neuropathic pain responsible for severe quality-of-life impairments. Awareness must therefore be raised among clinicians of the somatosensory and autonomic symptoms that can reveal small fiber neuropathy, appropriate diagnostic investigations, most common causes, and best treatment options for each patient profile. To help achieve this goal, the present review article discusses the clinical presentation of neuropathic pain and paresthesia and/or autonomic dysfunction due to involvement of nerves supplying exocrine glands and smooth muscle; normal findings from standard electrophysiological investigations; most informative diagnostic tests (epidermal nerve fiber density in a skin biopsy, laser-evoked potentials, heat- and cold-detection thresholds, electrochemical skin conductance); main causes, which consist chiefly of metabolic diseases (diabetes mellitus, glucose intolerance), dysimmunity syndromes (Sjögren's syndrome, sarcoidosis, monoclonal gammopathy), and genetic abnormalities (familial amyloidosis due to a transthyretin mutation, Fabry disease, sodium channel diseases); and the available symptomatic and etiological treatments...

To evaluate the effectiveness of low-level laser therapy (LLLT) in the treatment of xerostomia in primary Sjögren's syndrome (SS), a randomized clinical trial of patients with dry mouth symptoms associated with primary SS receiving care at a university hospital was conducted. Sixty-six patients were randomly assigned with a 1:1 allocation ratio to receive LLLT (laser group, n = 33) or placebo treatment (placebo group, n = 33). Patients in the laser group received LLLT twice a week for 6 weeks, for a total of 12 treatment sessions...

Dry eye disease (DED), defined as a multifactorial disease of tears and ocular surface, results in symptoms of discomfort, ocular irritation, visual disturbance and tear film instability. This syndrome is accompanied of ocular surface inflammation and it is produced by a deficient activity of the lacrimal functional unit. In addition, it is associated with systemic autoimmune diseases such as Sjögren´s Syndrome, rheumatoid arthritis, systemic lupus erythematosus and some drug administration. The treatment of dry eye disease is based on the typical signs and symptoms of dry eye, which are associated with hyperosmolarity, ocular surface inflammation, discomfort, visual disturbance, and tear film instability...

Purpose: Sjögren's syndrome is a systemic chronic autoimmune inflammatory disease that primarily targets the salivary and lacrimal glands (LGs). Currently there is no cure; therefore, cell-based regenerative therapy may be a viable option. LG inflammation is facilitated by extracellular ATP and mediated by the Pannexin-1 (Panx1) membrane channel glycoprotein. We propose that suppression of inflammation through manipulation of Panx1 activity can stimulate epithelial cell progenitor (EPCP) engraftment...

The mutualistic interaction between the gut microbiota (GM) and its host profoundly shapes many aspects of our physiology. The composition and activity of the gut microbiota is modulated by environmental factors such as dietary habits and antibiotic treatments. In rodents, studies demonstrate that the GM is a crucial regulator of bone metabolism and that modulation of the GM composition by probiotic interventions can prevent castration-induced bone loss. Short-term colonization of germ-free mice with GM results in an activation of CD4+T cells, resulting in increased levels of pro-inflammatory cytokines in bone and thereby activation of osteoclastic bone resorption...

There is an unmet need to reliably and non-invasively monitor disease progression in preclinical Huntington's disease (HD) models. As a marker of axonal damage, neurofilament light chain (NfL) has been suggested a marker for neurodegeneration. NfL concentrations in blood and CSF were recently shown to have prognostic value for clinical HD progression and brain atrophy. We therefore hypothesized that CSF and blood NfL concentrations could be useful preclinical HD markers, reflecting underlying pathology. To test our hypothesis we utilized the R6/2 mouse model of HD and measured NfL concentrations in CSF and serum using the ultrasensitive Single molecule array (Simoa) platform...

Lupus alopecia is usually difficult to treat. We report a case of a 40-year-old woman with Sjögren's syndrome and atopic dermatitis who presented with discoid lupus erythematosus on the forearms and lupus erythematosus profundus with alopecia involving the scalp. A biopsy specimen taken from the discoid lupus erythematosus lesion on the forearm further exhibited a xanthomatous reaction, which however was not detected in another specimen from the lupus erythematosus profundus on the scalp. Treatment with oral hydroxychloroquine showed dramatic effects and complete hair regrowth was obtained 3 months later...
