Proinflammatory cytokines are thought to modulate pathogeneses of various inflammatory bowel diseases (IBDs). Thymic stromal lymphopoietin (TSLP), which has been studied in various allergic diseases such as asthma, atopic dermatitis (AD) and eosinophilic esophagitis (EoE), has been less considered to be involved in IBDs. However, mucosal dendritic cells (DCs) induced by various cytokines including TSLP were reported to cause polarization of T cell toward Th2 response, the differentiation of regulatory T-cell (Treg), and secretion of IgA by B cells...

Interstitial lung disease (ILD) has been reported in 3 to 11% of patients with primary Sjögren's syndrome (pSS). The aims of this retrospective multicenter study were to: 1) analyze characteristics and outcome of ILD in pSS; and 2) evaluate predictive factors associated with ILD onset and deterioration. Twenty-one of 263 patients with pSS (8%) developed ILD. ILD onset preceded pSS diagnosis (n=5), was concurrently identified in association with pSS (n=6) and developed after pSS onset (n=9). Presenting ILD manifestations were: acute/subacute (n=11) onset of ILD, symptomatic progressive onset of ILD (n=5), and asymptomatic patients exhibiting abnormalities consistent with ILD on PFTs and HRCT-scan (n=5)...

The management of patients with chronic pain is a nearly daily challenge to rheumatologists, neurologists, orthopedic surgeons, pain specialists and indeed a issue in nearly every clinical practice. Among the myriad of causes of pain are often included a unique syndrome, generally referred to as complex regional pain syndrome type I (CRPS). Unfortunately this CRPS I has become a catch all phase and there are serious questions on whether it exist at all; this has led to an extraordinary number of poorly defined diagnostic criteria...

The term Guillain-Barré syndrome (GBS), the most frequent cause of acute paralytic neuropathy, covers a number of recognisably distinct variants. The exact cause of GBS is unknown, but 50-70% of cases appear 1-2weeks after a respiratory or gastrointestinal infection, or another immune stimulus that induces an aberrant autoimmune response targeting peripheral nerves and their spinal roots. The interplay between the microbial and host factors that dictate whether and how the immune response shifts towards autoreactivity is still unclear, and nothing is known about the genetic and environmental factors that affect an individual's susceptibility to the disease...

Galectins are evolutionary conserved β-galactoside binding proteins with a carbohydrate-recognition domain (CRD) of approximately 130 amino acids. In mammals, 15 members of the galectin family have been identified and classified into three subtypes according to CRD organization: prototype, tandem repeat-type and chimera-type galectins. Galectin-3 (gal-3) is the only chimera type galectin in vertebrates containing one CRD linked to an unusual long N-terminal domain which displays non-lectin dependent activities...

Autoimmune diseases result from an interplay of genetic predisposition and factors which stimulate the onset of disease. Mercury (Hg), a well-established toxicant, is an environmental factor reported to be linked with autoimmunity. Hg exists in several chemical forms and is encountered by humans in dental amalgams, certain vaccines, occupational exposure, atmospheric pollution and seafood. Several studies have investigated the effect of the various forms of Hg, including elemental (Hg(0)), inorganic (iHg) and organic mercury (oHg) and their association with autoimmunity...

Psoriatic arthritis (PsA) is a psoriasis (Ps)-associated inflammatory joint disease that affects peripheral joints, entheses, spine, and eyes. PsA and Ps are likely to be the same disease. PsA develops in nearly 70% of patients with Ps, and the hallmark of the disease is bone erosions and bone formation. Both innate and adaptive immunity appear to contribute to pathogenesis of PsA and Ps. Trauma may be a trigger factor for both PsA and Ps. The same T cell clones were reported to be present in both synovial tissues and skin lesions suggesting that a common antigen drives T cell immune response in the joints and skin lesions of patients with PsA...

Reliable autoantibody detection is important for early diagnosis and appropriate treatment of autoimmune disorders. However, in contrast to testing for classical clinical chemistry analytes, autoantibody testing is complex and evolving. Moreover, there is a lack of standardization. Nevertheless, it is important that laboratories that provide autoimmune tests comply with the requirements set forward by general international accreditation bodies. In the present manuscript, an ad hoc committee of the European Autoimmunity Standardisation Initiative (EASI) group provides background information on accreditation and identifies the minimum requirements needed to set up an accredited autoimmunity lab and to ensure that high-quality results are provided (in terms of personnel, procedures, validation, quality control, and reporting)...

The idiopathic inflammatory myopathies (IIMs) are a heterogeneous group of systemic muscle conditions that are believed to be autoimmune in nature. They have distinct pathological features, but the aetiopathogenesis of each subtype remains largely unknown. Recently, there has been increased interest in the complex role the innate immune system plays in initiating and perpetuating these conditions, and how this may differ between subtypes. This article summarises the traditional paradigms of IIM pathogenesis and reviews the accumulating evidence for disturbances in innate immune processes in these rare, but debilitating chronic conditions...

Macrophage activation syndrome (MAS) is a rare, life-threatening disease in which early diagnosis and aggressive therapeutic strategy may improve the outcome. Due to its rarity, epidemiologic data are still lacking. Hyperferritinemia is frequently associated with MAS and might modulate the cytokine storm, which is involved in the development of multiple organ failure. In this paper, we investigated clinical data, treatments, and outcome of a homogeneous cohort of 41 adult MAS patients, complicating autoimmune rheumatic diseases...

Autoimmune reactions reflect an imbalance between effector and regulatory immune responses, typically develop through stages of initiation and propagation, and often show phases of resolution (indicated by clinical remissions) and exacerbations (indicated by symptomatic flares). The fundamental underlying mechanism of autoimmunity is defective elimination and/or control of self-reactive lymphocytes. Periodontal diseases are characterized by inflammatory conditions that directly affect teeth supporting structures which are the major cause of tooth loss...

Inflammatory T cells are thought to be central to the pathogenesis of juvenileidiopathicarthritis. In particular, recentevidencehasunderlined the importance of a balance between Th17 and Tregcells. Severalmechanismshave come to light that control thisreciprocalrelationship.Moreover, ithasbeenshownthat in certainconditions Th17 cells can shifttoward a non classic Th1 phenotype. Anti-rheumaticbiologictherapiesmayinterfere with thesemechanisms and re-establish immune tolerance.

BACKGROUND AND OBJECTIVE: Statin-associated autoimmune myopathy (SAAM) with anti-HMGCR antibodies has recently been described. Several specific immunoassays are in use to detect HMGCR antibodies. In the course of systematic autoantibody screening we recognized a new distinct IFL staining pattern on rat liver sections that regularly coincided with anti-HMGCR antibodies. In this study we investigated whether this new IFL pattern is specifically associated to statin-associated autoimmune myopathy and corresponds to anti-HMGCR antibodies...

Hepatitis C virus (HCV) infection is responsible for both hepatic and extra-hepatic disorders (HCV-EHDs); these latter are correlated on one hand clearly with HCV lymphotropism causing immune-system dysregulation as well as with viral oncogenic potential, and on the other hand probably with chronic inflammatory status causing cardio-metabolic complications as well as neurocognitive disturbances. The spectrum of HCV-EHDs ranges from mild or moderate manifestations, such as arthralgia, sicca syndrome, peripheral neuropathy, to severe, life-threatening complications, mainly vasculitis and neoplastic complications...

Microbial transglutaminase (mTg) is capable of cross-linking numerous molecules. It is a family member of human tissue transglutaminase (tTg), and is involved in CD. Despite declarations of the safety of mTg for industrial use, direct evidence for immunogenicity of the enzyme is lacking. The serological activity of mTg, tTg, gliadin complexed mTg (mTg neo-epitope) and gliadin complexed tTg (tTg neo-epitope) were studied in 95 pediatric celiac patients (CD), 99 normal children (NC), 79 normal adults (NA) and 45 children with nonspecific abdominal pain (AP)...

We have evaluated prospectively the prevalence of other autoimmune disorders in outpatient clinic in 3069 consecutive patients with diagnosed chronic autoimmune thyroiditis (AT), with respect to two age- and sex-matched control groups: a) a control group of 1023 subjects, extracted from a random sample of the general population without thyroid disorders; b) 1023 patients with non-toxic multinodular goiter extracted from the same random sample of the general population, with similar iodine intake. The results of our study demonstrate a significant increase of the prevalence of autoimmune disorders in AT patients (with respect to both controls), for the following diseases: chronic autoimmune gastritis (CAG), vitiligo (Vit), rheumatoid arthritis, polymialgia rheumatica (Polym), celiac disease, diabetes, sjogren disease, multiple sclerosis, systemic lupus erythematosus, sarcoidosis, alopecia, psoriathic arthritis, systemic sclerosis, and HCV-related cryoglobulinemia...
