BACKGROUND: Th9 cells are a newly discovered CD4+ T helper cell subtype, characterized by high interleukin (IL)-9 secretion. Growing evidences suggest that Th9 cells are involved in the pathogenic mechanism of multiple sclerosis (MS). Mast cells are multifunctional innate immune cells, which are perhaps best known for their role as dominant effector cells in allergies and asthma. Several lines of evidence point to an important role for mast cells in MS and its animal models. Simultaneously, there is dynamic "cross-talk" between Th9 and mast cells...

The serum pepsinogen (PG) assay findings are correlated with the status of Helicobacter pylori infection, but there are controversies on the link with upper gastrointestinal (UGI) endoscopic findings. The aim of this study was to determine the significance of a serum PG assay for correlating with endoscopic findings in H. pylori-seroprevalent adult population. Korean adults who visited for a health check-up were included consecutively. Subjects after gastrectomy or H. pylori eradication were excluded. After completing the serum PG assay and anti-H...

BACKGROUND: Myasthenia gravis (MG) is an autoimmune disease of the neuromuscular junction (NMJ), characterized with muscle weakness. While MG develops due to acetylcholine receptor (AChR) antibodies in most patients, antibodies to muscle-specific receptor tyrosine kinase (MuSK) or low-density lipoprotein receptor-related protein 4 (LRP4) may also be identified. Experimental autoimmune myasthenia gravis (EAMG) has been previously induced by both LRP4 immunization and passive transfer of LRP4 antibodies...

IgG4-related disease is characterized by multi-system inflammation and possible elevation in serum immunoglobulin-G4 level. Treatment regimens include glucocorticoids, disease-modifying anti-rheumatic agents and recently, rituximab infusions have been reported to be effective in treatment-refractory disease. We present a case of a 64-year-old male presenting with acute abdominal pain and scleral icterus. An abdominal ultrasound demonstrated extensive biliary ductal dilatation. A computed tomography (CT) scan and a magnetic resonance cholangiopancreatography (MRCP) revealed a 4...

IgG4-related disease (IgG4-RD) is a fibro-inflammatory disorder involving virtually every organ with a risk of organ dysfunction. Despite recent studies regarding B cell and T cell compartments, the disease's pathophysiology remains poorly understood. We examined and characterized subsets of circulating lymphocytes in untreated patients with active IgG4-RD. Twenty-eight consecutive patients with biopsy-proven IgG4-RD were included in a prospective, multicentric study. Lymphocytes' subsets were analyzed by flow cytometry, with analysis of TH1/TH2/TH17, TFH cells, and cytokine release by peripheral blood mononuclear cells...

BACKGROUND: Pancreatic autoantibodies (PABs) are detected in patients with inflammatory bowel disease (IBD). Their prevalence is higher in Crohn's disease (CrD) than in ulcerative colitis (UC). Glycoprotein 2 (GP2) and, more recently, CUB and zona pellucida-like domain-containing protein 1 (CUZD1) have been identified as target autoantigens of PAB. The clinical utility of CUZD1 autoantibodies has only recently been assessed by indirect immunofluorescence (IIF) assays. In this study, we developed and validated novel immunoassays for the detection of CUZD1 autoantibodies...

The main symptoms of irritable bowel syndrome (IBS) include abnormal frequency of bowel movements. On this basis, three main clinical types of the disease have been distinguished, i.e.: constipation (IBSC), diarrhea (IBS-D) and mixed-type (IBS-M) in accordance with the Rome III criteria. These disorders mainly affect the colon, but symptoms related to upper gastrointestinal tract are also often observed. AIM: The aim of the study was to assess the oro-caecal transit time in patients with irritable bowel syndrome with IgG-dependent hypersensitivity to cereal products...

Pemphigus vulgaris (PV) is an autoimmune disease characterized by the presence of IgG autoantibodies against desmoglein-3. Despite the variety of findings, the chemokine and cytokine profiles that characterize the immune response in the disease are still poorly explored. Thus, 20 PV patients and 20 controls were grouped according to gender, ethnicity, place of residence, and clinical parameters of the disease. Then, the levels of chemokines and of Th1/Th2/Th17/Treg/Th9/Th22-related cytokines were assessed in the serum...

OBJECTIVE: The interleukin 17 (IL-17) cytokine family is involved in a number of chronic inflammatory diseases. In spite of contradictory findings and a lack of causality in clinical studies, IL-17 inhibition for systemic lupus erythematosus (SLE) has regained attention as a potential therapeutic pathway, after demonstrating disease-modifying capabilities in ankylosing spondylitis. We investigated the clinical associations of interleukin 17 A (IL-17A) in patients with SLE. MATERIAL AND METHODS: A cross-sectional study was performed involving SLE patients (n=102; age: 49 years; 86% female) recruited from a regional registry...

BACKGROUND: In children with Henoch-Schonlein purpura nephritis (HSPN), the degree of proteinuria has been proven to be not only a sign of kidney damage, but also an accelerator of kidney disease progression. Nephrotic proteinuria at disease onset has been proposed as a predictor of a poor renal outcome. This study aims to assess the clinical and pathological features of HSPN with nephrotic proteinuria in a single center. METHODS: One hundred thirty-seven patients with HSPN who visited Shanghai Children's Hospital from January 2009 to December 2013 were retrospectively reviewed...

Pituitary autoimmunity, considered a synonym of autoimmune hypophysitis, defines a wide spectrum of conditions (neoplastic, functional, and iatrogenic pituitary disorders; and extra-pituitary autoimmune and non-autoimmune diseases), and is characterized by the presence of antipituitary antibodies (APAs) at various titer and prevalence. These conditions have been increasingly recognized not only in adults, but also in children. The autoimmune pathogenesis, histological features of the primary (i.e. lymphocytic, granulomatous, xanthomatous, IgG-4 related lymphoplasmacytic, and necrotizing) forms, and the pathognomonic association of lymphocytic hypophysitis with pregnancy and CTLA-4 antibody therapy, have been clearly demonstrated...
