Non celiac gluten sensibility

Brunetta Porcelli, Fabio Ferretti, Carla Vindigni, Lucia Terzuoli
BACKGROUND: Celiac disease (CD) is an immune-mediated intolerance to dietary gluten, affecting genetically predisposed individuals. ELISA-based serological tests help to decide if further duodenal biopsy is necessary, for this the diagnostic kits have to be accurate, specific, and sensible. In this study, we investigate the performance of an ELISA that uses the purified cross-linked complex of tissue transglutaminase and gliadin, referred as the "neoepitope" (AESKULISA® tTG New Generation), as antigen...

UNLABELLED: The coeliac disease is an immune-mediated enteropathy triggered by an ingestion of gluten in genetically susceptible individuals. Like some other systemic diseases (Crohn's disease, Sjögren's syndrome) the celiac disease is able to alter the oral ecosystem and the composition of the saliva. AIM: The aim of this retrospective study has been to examine the incidence of coeliac disease (CD) in paediatric population and to search the presence of anti-transglutaminase auto-antibodies (anti-tTG) in saliva, comparing and quantifying the concentration regard to the serum values of the anti-tTG auto-antibodies, before and after six months from the beginning of the free gluten diet...

It is known that celiac disease is characterized by a huge variety of clinical forms ranging from classical ones to silent forms, potential ones and to an increased number of cases of gluten-sensitivity. The latter is an abnormal non-allergic sensibility to gluten. Clinical manifestations can be very different without a severe intestinal damage (Marsh/Oberhuber 0-I) and this condition seems to benefit from a gluten free diet. Cases of gluten-sensitivity appear very interesting in the search of histological markers with elevated specificity, which are able to identify slight and early gluten dependent enteropathy, especially in at risk patients for celiac disease even before classical autoantibodies appear: for instance, this is the case of intraepithelial lymphocytes T-cell receptor gamma delta and mucosal deposits of class IgA anti transglutaminase antibodies...

BACKGROUND/AIMS: To assess the sensitivity and specificity of IgA and IgG tissue-transglutaminase antibodies assay, the pattern of antibody decline after gluten withdrawal and their modifications with reference to dietary compliance. SUBJECTS: We studied sera from 143 untreated coeliac children and adolescents (8.8+/-6.1 years), 212 sera from 97 of those patients after gluten withdrawal, and 64 control subjects with non-coeliac intestinal disorders (6.8+/-4.8 years)...

The coeliac disease (CD) or gluten-sensitive enteropathy (GSE) is a permanent intolerance to wheat gliadin and to correlated proteins inducing malabsorption and typical damages of the jejunal mucosa (total or subtotal villous atrophy = SVA) in genetically-predisposed individuals ("DQW2"). A large amount of research has been devoted to CD pathogenesis: the most recent studies, thanks to sophisticated and experimental methods, support the pathogenetic immunological theory and the one of direct cytotoxicity. The correct diagnostic procedure for CD, established in 1970 by the European Society for Pediatric Gastroenterology and Nutrition (ESPGAN), suggested three small bowel mucosal biopsies...
