Tissue transglutaminase is a ubiquitous and multifunctional protein that contribute to several processes such as apoptosis/survival, efferocytosis, inflammation and tissue repairing under physiological and pathological conditions. Several activities can be associated with well established functional domains; in addition, four RNA alternative splice variants have been described, characterized by sequence divergences and residues deletion at the C-terminal domains Tissue transglutaminase is recognized as the central player in the physiopathology of celiac disease mainly through calcium dependent enzymatic activities...

Despite being widely used for several years, the endovascular aortic repair (EVAR) of a thoracoabdominal aneurysm (TAAA) remains challenging, particularly the revascularization of the abdominal aortic visceral branches. A 66-year-old male was admitted to hospital with abdominal bloating and pain. Computed tomographic angiography (CTA) confirmed a Crawford type III TAAA from the distal descending aorta to the suprarenal abdominal aorta that involved the celiac axis, accompanied with an occlusion of the left subclavian artery...

Diabetes mellitus is a systemic disease which affects patients of various age. Hyperglycemia induces damage of vascular endothelium, development of chronic inflammation, organic and functional lesions in several systems and organs. The principal gastroenterological complaints linked to the manifestation of the disease include abdominal pain, diarrhea, nausea, flatulence, and vomiting. However, complications in the alimentary system may manifest exclusively by difficulties in reaching normoglycemia and numerous persistent episodes of hypoglycemia...

Background: Celiac disease (CD) patients adhering to a gluten-free diet (GFD) are exposed frequently to low levels of gluten that contribute to symptoms and persistent intestinal histologic damage. Objective: We analyzed prior clinical data to determine how much gluten is accidentally consumed while on a GFD. The aim was to understand the range of gluten consumption for a wide distribution of CD patients. Design: A meta-analysis was conducted on data from 2 different clinical programs: 1) measurements of gluten in stool and urine in CD and non-CD populations; and 2) analysis of data from trials for the investigational therapeutic latiglutenase...

Patients with celiac disease (CD) frequently suffer from iron deficiency anemia (IDA) and may benefit from iron supplementation. However, intolerance to iron sulfate and duodenal atrophy could reduce the efficacy of this supplementation. This study evaluated the efficacy of a new sucrosomial iron formulation in patients with CD. Consecutive patients with CD and IDA were divided into two groups: patients with a known intolerance to iron sulfate were treated with sucrosomial iron (30 mg of iron/day), while those receiving iron supplementation for the first time were assigned to iron sulfate (105 mg of iron/day)...

Since the discovery of HLA 60 years ago, it has contributed to the understanding of the immune system as well as of the pathogenesis of several diseases. Aside from its essential role in determining donor-recipient immune compatibility in organ transplantation, HLA genotyping is meanwhile performed routinely as part of the diagnostic work-up of certain autoimmune diseases. Considering the ability of HLA to influence thymic selection as well as peripheral anergy of T cells, its role in the pathogenesis of autoimmunity is understandable...

Several viruses induce intestinal epithelial cell death during enteric infection. However, it is unclear whether pro-apoptotic capacity promotes or inhibits replication in this tissue. We infected mice with two reovirus strains that infect the intestine but differ in the capacity to alter immunological tolerance to new food antigen. Infection with reovirus strain T1L, which induces an inflammatory immune response to fed antigen, is prolonged in the intestine, whereas T3D-RV, which does not induce this response, is rapidly cleared from the intestine...

We present two cases of patients with severe persistent diarrhoea, in whom duodenal biopsies revealed villous atrophy that could be attributed to the use of olmesartan. The differential diagnosis of villous atrophy without serological markers of celiac disease should include drugs as possible cause, with olmesartan as a recently discovered culprit. Gastroenterologist should be aware of this entity.

BACKGROUND: Several studies indicated that multiple sclerosis (MS) is frequently associated with other autoimmune diseases. However, it is little known if the coexistence of these conditions may influence the radiologic features of MS, and in particular the brain volumes. OBJECTIVES: To evaluate the effect of autoimmune comorbidities on brain atrophy in a large case-control MS population. METHODS: A group of MS patients affected by a second autoimmune disorder, and a control MS group without any comorbidity, were recruited...

OBJECTIVES: Several studies have reported that the intestinal microbiota composition of celiac disease (CD) patients differs from healthy individuals. The possible role of gut microbiota in the pathogenesis of the disease is, however, not known. Here, we aimed to assess the possible differences in early fecal microbiota composition between children that later developed CD and healthy controls matched for age, sex and HLA risk genotype. MATERIALS AND METHODS: We used 16S rRNA gene sequencing to examine the fecal microbiota of 27 children with high genetic risk of developing CD...

PURPOSE: This study was conducted to assess the prevalence and significance of "haziness" around the hepatic artery and celiac axis in patients after pancreaticoduodenectomy. METHODS: This retrospective study was conducted on 116 patients who underwent pancreaticoduodenectomy or a similar procedure and had no clinical evidence of tumor recurrence or malignancy within 2 years from the date of surgery. RESULTS: Most images exhibited at least mild to moderate haziness around the hepatic artery and celiac axis...

Small intestinal histologic abnormalities in celiac disease include atrophy of the intestinal villi, hypertrophy of the crypts and lymphocytic infiltration of intraepithelial spaces and lamina propria. These findings are central to diagnosis and their severity and change over time are valuable to monitor disease course and response to therapy. Subjective methods to grade celiac disease histological severity include the Marsh-Oberhuber and Corazza-Villanacci systems. Quantitative histology uses villus height (Vh), crypt depth (Cd), and intra-epithelial lymphocyte count (per 100 enterocytes) to provide objective measures of histologic changes including Vh:Cd ratio...

Reperfusion syndrome (RS) after revascularization of an arterial occlusion of the lower leg is a well-known complication. RS after splanchnic revascularization, however, is an infrequent and less-known phenomenon. We present a patient with persisting abdominal complaints after revascularization of the celiac trunk and superior mesenteric artery suggesting reocclusion. Although computed tomography angiography showed patent splanchnic arteries, an impressive hyperperfusion state of liver and spleen was visualized...

INTRODUCTION: Celiac artery (CA) occlusions/stenosis are infrequently associated with liver ischemia due to its unique vascularization where portal vein provides about 75% of liver's perfusion. Collateral flow from gastroduodenal artery also provides, in most cases, enough blood supply to prevent ischemic hepatitis. In cases where these collateral pathways are compromised severe liver ischemia can occur. METHODS: We present a case of acute mesenteric ischemia following gastric surgery that was treated with a hybrid retrograde CA stenting...

Celiac disease (CD) is a chronic, autoimmune disease of the small intestine with a strong but complex genetic component. The disease is triggered by the consumption of dietary gluten through the presentation of immunogenic gliadin peptides to T helper lymphocytes by HLA-DQ2 and DQ8 heterodimers, which are the major contributors to the genetic risk. Recent large-scale genotyping efforts have identified a large number of additional association signals, but the functional role of the underlying genes in the pathogenesis of the disease is still unclear...

Celiac disease is an autoimmune disorder due to the inflammatory response to gluten in genetically predisposed individuals. It causes an enteropathy associated with several nutritional complications. Strict compliance to a gluten-free diet (GFD) is the current primary therapy. Nonceliac gluten sensitivity (NCGS) is a condition in which gluten ingestion leads to systemic symptoms but is not associated with small bowel atrophy or abnormal celiac serologies. A GFD heals celiac disease enteropathy and improves symptoms in NCGS...

OBJECTIVE: Optimal treatment of spontaneous isolated celiac artery dissection (SICAD) is not well established because the natural history of this rare disease is poorly understood. We analyzed the natural history of patients who underwent conservative treatment. METHODS: The study included 28 patients with SICAD from December 2008 to January 2017. Our institutional policy of first-line treatment for SICAD patients was conservative, and invasive procedures were reserved for unstable complications such as severe persistent pain, significant organ malperfusion, rapid aneurysmal change, and rupture or concealed rupture...

OBJECTIVE: To evaluate the proportion of children with moderate to severe iron-deficiency anemia who have associated celiac disease. METHODS: This cross-sectional analytical study was conducted among children aged 1 to 12 years of age with moderate-to-severe iron deficiency anemia and control children without anemia. Serum IgA-tissue trans-glutaminase levels were assessed in both cases and controls. All children with positive celiac serology underwent upper gastrointestinal endoscopy and duodenal biopsy; biopsy finding of Marsh grade 3 was considered positive for celiac disease...
