Background: Non-celiac gluten sensitivity (NCGS) is a clinical entity characterized by intestinal and/or extra-intestinal symptoms related to the ingestion of gluten in individuals that are not affected by either celiac disease (CD) or wheat allergy (WA). Since we do not have specific biomarkers for NCGS, the diagnosis is based on the evidence of a clear relationship between the ingestion of gluten (re-challenge) and clinical symptoms, after a remission during the gluten-free diet (GFD). Several re-challenge studies have been published so far to evaluate the real prevalence of NCGS, reporting conflicting results...

Celiac disease (CD) can be considered a complex multi-organ disorder with highly variable extra-intestinal, including neurological, involvement. Cerebellar ataxia, peripheral neuropathy, seizures, headache, cognitive impairment, and neuropsychiatric diseases are complications frequently reported. These manifestations may be present at the onset of the typical disease or become clinically evident during its course. However, CD subjects with subclinical neurological involvement have also been described, as well as patients with clear central and/or peripheral nervous system and intestinal histopathological disease features in the absence of typical CD manifestations...

Celiac disease is an autoimmune disorder triggered in genetically predisposed individuals by the ingestion of gluten proteins from wheat, barley, and rye. The -gliadin gene family of wheat contains four highly stimulatory peptides, of which the 33-mer is the main immunodominant peptide in celiac patients. We designed two sgRNAs to target a conserved region adjacent to the coding sequence for the 33-mer in the -gliadin genes. Twenty-one mutant lines were generated, all showing strong reduction in -gliadins. Up to 35 different genes were mutated in one of the lines of the 45 different genes identified in the wild type, while immunoreactivity was reduced by 85%...

Psoriasis is a chronic inflammatory immune-mediated disorder associated and often coexisting with many other immune-related clinical conditions including those affecting the gastrointestinal tract. Data obtained from the reviewed literature suggest an association between psoriasis and pathologies of the oral cavity, both psoriasis-specific lesions, as well as non-specific, such as geographic tongue or fissured tongue. These findings show the importance of thorough examination of oral mucosa in psoriatic patients...

INTRODUCTION: Modern-era systemic therapy for locally advanced pancreatic adenocarcinoma (LAPC) offers improved survival relative to historical regimens but not necessarily improved radiographic downstaging to allow more patients to undergo resection. The aim of this study was to evaluate the survival, progression, and pathologic outcomes after resection of LAPC that did not regress from > 180 degrees arterial encasement after neoadjuvant therapy. METHODS: Sixty-one LAPC patients were brought to the operating room after neoadjuvant therapy for NCCN-defined unresectable pancreatic cancer between 2012 and 2017...

Polyglandular autoimmune syndrome (PAS) type 3 consists of autoimmune thyroid disease (AITD) coexisting with ≥1 non-thyroidal autoimmune disease (NTAID) other than Addison's disease and hypoparathyroidism. We evaluated the prevalence and repertoire of thyroid hormones antibodies (THAb) in PAS-3 patients. Using a radioimmunoprecipation technique, we measured THAb (T3IgM, T3IgG, T4IgM, and T4IgG) in 107 PAS-3 patients and 88 controls (patients with AITD without any NTAID). Based on the selective coexistence of AITD with one NTAID (chronic autoimmune gastritis, non-segmental vitiligo or celiac disease), patients were divided into group 1 (chronic autoimmune gastritis positive, n = 64), group 2 (non-segmental vitiligo positive, n = 24), and group 3 (celiac disease positive, n = 15)...

The presence of the meandering mesenteric artery, which is a non-constant tortuous arterial component unifying the peripheral intestinal circulation, is evidence of chronic occlusive disease of the main intestinal arteries. This collateral intestinal arterial pathway, when present, must be preserved in any abdominal intervention, as it is often the only remaining arterial supply of the intestine; its ligation can be accompanied by intestinal ischemia. We present herein, the case of a 42-year old man, heavy smoker, who had chronic mesenteric ischemia without particular clinical manifestations till the hospitalization for acute myocardial infarction for which he underwent balloon angioplasty and stenting of the left circumflex coronary artery...

INTRODUCTION: Non-occlusive mesenteric ischemia (NOMI) develops without anatomical causes. Early diagnosis is challenging and treatments are of questionable effectiveness. We investigated the role of complement activation in the pathophysiology of NOMI in animal models through the inhibition of complement C5a. MATERIALS AND METHODS: 60-min partial aortic occlusion (PAO; abdominal aorta, proximal to celiac trunk; mean arterial pressure: 30-40 mmHg) was established in Sprague-Dawley rats (n = 28) and 60-min cardiac tamponade in minipigs (n = 19; mean arterial pressure: 40-50 mmHg) to observe short- and long-term circulatory and inflammatory consequences of NOMI...

Knowing whether or not a food contains gluten is vital for the growing number of individuals with celiac disease and non-celiac gluten sensitivity. Questions have recently been raised about whether beef from conventionally-raised, grain-finished cattle may contain gluten. To date, basic principles of ruminant digestion have been cited in support of the prevailing expert opinion that beef is inherently gluten-free. For this study, gluten analysis was conducted in beef samples collected using a rigorous nationally representative sampling protocol to determine whether gluten was present...

Transglutaminase 2 (TG2) is an inducible transamidating acyltransferase that catalyzes Ca(2+)-dependent protein modifications. In addition to being an enzyme, TG2 also serves as a G protein for several seven transmembrane receptors and acts as a co-receptor for integrin β1 and β3 integrins distinguishing it from other members of the transglutaminase family. TG2 is ubiquitously expressed in almost all cell types and all cell compartments, and is also present on the cell surface and gets secreted to the extracellular matrix via non-classical mechanisms...

OBJECTIVE: The prevalence of celiac disease (CD) has increased significantly in recent years, and risk prediction and early diagnosis have become imperative especially in at-risk families. In a previous study, we identified individuals with CD based on the expression profile of a set of candidate genes in peripheral blood monocytes. Here we evaluated the expression of a panel of CD candidate genes in peripheral blood mononuclear cells from at-risk infants long time before any symptom or production of antibodies...
