Subacute cutaneous lupus erythematosus (SCLE) is a well-defined subtype of lupus erythematosus, characterised by photosensitivity, annular and/or psoriasiform lesions, variable systemic involvement and presence of circulating SSA/anti-Ro antibodies. SCLE may be idiopathic or drug-induced. Both the idiopathic and drug-induced forms of SCLE are analogous in their clinical, serological and histological features. Drug-induced SCLE has been reported with various oral agents, but to our knowledge this is the first reported case due to a topical medication...

In normal colonic epithelium, the proliferative zone is limited to the lower half of the colonic crypt. Evaluating the changes in the colonic epithelial proliferation can be useful in understanding pathophysiology of various diseases. Our aim was to investigate the proliferative compartment of serrated polyps (SPs) using MCM2, a protein involved in DNA replication, and assess for changes along the SP spectrum. Immunohistochemistry was performed on serrated polyps (16 microvesicular-type hyperplastic polyps (HP), 58 sessile serrated adenomas (SSA), seven SSAs with dysplasia) and six sections of normal colon using anti-MCM2 antibody...

Antisynthetase syndrome (ASS) is recognized as a subgroup of idiopathic inflammatory myopathies (IIMs). It is associated with autoantibodies directed against aminoacyl-transfer ribonucleic acid (tRNA) synthetase enzymes. We report the first case of anti-PL-7/anti-SSA 52kD ASS presenting as acute digital ischemia, an association not described previously. Occlusive vasculopathy is a rare but serious manifestation that can be seen at presentation in patients with ASS and may herald the onset of severe interstitial lung disease (ILD)...

Neonatal Lupus Syndrome (NLS) is a distinct clinical entity caused by transplacental passage of maternal anti-SSA/Ro antibodies (Ab). Mothers may have systemic lupus erythematosus, Sjögren syndrome, or other connective tissue disease, or may be completely healthy at the time of giving birth. NLS includes several clinical manifestations: complete congenital heart block (CCHB) and cutaneous lupus are the most common, while hepatobiliary disease, hematological manifestations and central nervous system involvement may occur...

Th17 related immune response is pathogenic in primary Sjögren's syndrome (pSS). However, the role of IL-17F, one potent inflammatory member of IL-17 family cytokines in pSS, has not been specifically defined. We recruited one hundred and nine pSS patients and forty-two healthy controls and their serum levels of IL-17A and IL-17F were determined by multiplex cytokine assays. White blood cell, red blood cell, neutrophil, lymphocyte, IgM, IgG, C3, C4, RF, ANA, anti-SSA antibody, and anti-SSB antibody were measured by standard laboratory techniques...

Anti-Ro/SS-A is one specific type of antinuclear antibodies. They are in the majority of cases associated with primary Sjögren syndrome (SS) but also in Systemic Lupus Erythematosus (SLE), rheumatoid arthritis (RA), and in healthy people. During pregnancy, they are mainly associated to congenital heart block (CHB) and neonatal lupus (NL). The aim of this study was to compare the rate of maternal and fetal complications between a series of anti-Ro/SS-A positive pregnant women prospectively followed. Forty-two anti-Ro/SSA antibodies positive pregnant women that were referred to our hospital between 2011 and 2015...

The detection of cardiac conduction defects in an 18-24 week old foetus in the absence of structural abnormalities predicts with near certainty the presence of autoantibodies against 60kD and 52kD SSA/Ro in the mother regardless of her health status. Previous studies have emphasized these autoantibodies as key mediators of tissue injury. The aim of this study was to focus on the anti-Ro52 response to determine whether these autoantibodies originate from progenitors that are inherently self-reactive or from B-cells that acquire self-reactivity during an immune response...

The objectives of this study were to examine the serum levels of interleukin (IL)-37 and its clinical association in patients with primary Sjögren's syndrome (pSS) and to investigate whether or not IL-37 participates in the regulation of the pathogenesis of pSS. ELISA was used to analyse the serum levels of IL-37, total IL-18 and IL-18 binding protein (IL-18BP). The level of free IL-18 was calculated based on the mass action law. The correlations between the IL-37 serum levels with the laboratory values and the total IL-18 and IL-18BP serum levels were analyzed by a Spearman's correlation test...

BACKGROUND: The association of primary Sjögren´s syndrome (SS) and amyloidosis has been recognized but scarcely assessed. OBJECTIVE: Herein we analyzed the literature regarding this association in order to describe a SS phenotype prone to both conditions. METHODS: PubMed and CINAHL databases were searched from inception until April 2016 for the key words: amyloidosis, amyloid, Sjögren's syndrome and their combinations. RESULTS: Most of the cases corresponded to localized amyloidosis mainly at skin and lung, whereas only three cases were systemic...

Sjogren's syndrome (SS) is a chronic autoimmune disorder characterized by lymphocytes infiltration in the exocrine glands. Central nervous system complications of primary SS are not rare, but ischemic stroke has been rarely reported. Here we report a 43-year-old female with a two-year history of primary SS, presenting with sudden cerebral infarction. Her primary SS was diagnosed on the basis of clinical features, high levels of serum anti-SSA and anti-SSB antibodies, salivary gland secretion evaluation and positive sublingual gland biopsy results...

OBJECTIVE: Fetuses exposed to anti-SSA (Sjögren's) antibodies are at risk of developing irreversible complete atrioventricular block (CAVB), resulting in death or permanent cardiac pacing. Anti-inflammatory treatment during the transition period from normal heart rhythm (fetal heart rhythm (FHR)) to CAVB (emergent CAVB) can restore sinus rhythm, but detection of emergent CAVB is challenging, because it can develop in ⩽24 h. We tested the feasibility of a new technique that relies on home FHR monitoring by the mother, to surveil for emergent CAVB...
