Refractory celiac disease and EATL patients show severe malnutrition and malabsorption at diagnosis Summary Background & aims: Refractory celiac disease type II (RCDII) and EATL (Enteropathy Associated T-cell Lymphoma) are (pre)malignant complications of celiac disease (CD). Data on malnutrition and intestinal absorption is lacking in these patients. Therefore, the aim of the study is to comprehensively assess nutritional status and intestinal absorption capacity of patients with RCDII and EATL, compared with data of newly diagnosed CD patients. Methods: Observational study in ...

Pediatric Celiac Disease: Follow-Up in the Spotlight 1,2 ABSTRACT The follow-up of celiac disease (CD) is challenging due to the scarcity of published data and the lack of standardized evidence-based protocols. The worldwide frequency and methods of CD follow-up appear to be heavily influenced by expert opinions of the individual physicians who assess children with CD. The aim of this review was to summarize the available studies on CD follow-up in children. We conducted a literature search with the use of PubMed, Medline, and Embase (from 1900 to 15 December 2016) for terms relevant ...

Nutritional profile of adult patients with celiac disease Abstract. – Celiac disease (CD) is a chronic immune-mediated gluten dependent enteropathy induced by ingestion of gluten, characterized by intestinal malabsorption and subtotals or total atrophy of intestinal villi. The predominant consequence of CD in untreated patients, is malnutrition as a result of malabsorption. Moreover, several and increasing extra-intestinal clinical manifestations have been described in the CD patients. Strict adherence to a gluten-free diet (GFD) improves nutritional status, inducing an inc...

Maternal and neonatal vitamin D status, genotype and childhood celiac disease  Background Low concentration of 25-hydroxyvitamin D during pregnancy may be associated with offspring autoimmune disorders. Little is known about environmental triggers except gluten for celiac disease, a common immune-mediated disorder where seasonality of birth has been reported as a risk factor. We therefore aimed to test whether low maternal and neonatal 25- hydroxyvitamin D predicted higher risk of childhood celiac disease. Methods and Findings In this Norwegian nationwide pregnancy cohort (n = ...

Intestinal Microbiota and Probiotics in Celiac Disease SUMMARY Celiac disease (CD) is a common chronic autoimmune enteropathy caused by gluten intake. To date, the only therapy for CD is the complete exclusion of dietary sources of grains and any food containing gluten. It has been hypothesized that the intestinal microbiota is somehow involved in CD. For this reason, probiotics are appearing as an interesting adjuvant in the dietetic management of CD. This review aims to discuss the characteristics of the microbiota in CD subjects and the use of probiotics as a novel therapy for ...

Indications and Use of the Gluten Contamination Elimination Diet for Patients with Non-Responsive Celiac Disease Abstract: For the majority of patients diagnosed with celiac disease, once a gluten-free diet is initiated, symptoms improve within weeks and may completely resolve in months. However, up to 30% of patients may show signs, symptoms or persistent small intestinal damage after one year on a gluten-free diet. These patients require evaluation for other common GI etiologies and assessment of their celiac disease status in order to make a diagnosis and suggest treatment. Here, ...

Effector and suppressor T cells in celiac disease Abstract Celiac disease (CD) is a T-cell mediated immune disease in which gliadin-derived peptides activate lamina propria effector CD4+ T cells. This activation leads to the release of cytokines, compatible with a Th1-like pattern, which play a crucial role in the pathogenesis of CD, controlling many aspects of the inflammatory immune response. Recent studies have shown that a novel subset of effector T cells, characterized by expression of high levels of IL-17A, termed Th17 cells, plays a pathogenic role in CD. While these ...

Effect of Gliadin on Permeability of Intestinal Biopsy Explants from Celiac Disease Patients and Patients with Non-Celiac Gluten Sensitivity Abstract: Background: Intestinal exposure to gliadin leads to zonulin upregulation and consequent disassembly of intercellular tight junctions and increased intestinal permeability. We aimed to study response to gliadin exposure, in terms of barrier function and cytokine secretion, using intestinal biopsies obtained from four groups: celiac patients with active disease (ACD), celiac patients in remission (RCD), non-celiac patients with gluten sensit...
