Celiac disease is a common immune-mediated disorder that occurs in individuals with permissive genetics (HLA-DQ2/DQ8 genotype) following exposure to certain wheat proteins. The histopathologic manifestations of small intestinal mucosal injury (villus atrophy, crypt hyperplasia, and intraepithelial lymphocytosis) are well recognized. However, these findings are not specific for celiac disease, because they are observed in other small intestinal disorders. Read More

Celiac disease is a chronic immune-mediated enteropathy triggered by exposure to dietary gluten in genetically predisposed individuals. Many genes involved in the pathogenesis have been identified and a crucial role is known to be played by the Human Leukocyte Antigen (HLA) system. The main determinants for genetic susceptibility are HLA-DQA1 and HLA-DQB1 genes encoding for HLA-DQ2 and HLA-DQ8 molecules, carried by almost all patients affected. Read More

Chronic autoimmune thyroid disease or Hashimoto thyroiditis (HT) and Graves-Basedow disease (GD) are the main autoimmune thyroid diseases in pediatric age. Both are characterized by the production of anti-thyroid antibodies, by an infiltration of autoreactive B and T lymphocytes into the thyroid parenchyma and by alterations in thyroid function (hyperthyroidism in GD, normal function or subclinical hypothyroidism in HT with possible evolution towards manifest hypothyroidism). Celiac disease (CD) is a systemic autoimmune disease caused by gluten ingestion in genetically predisposed subjects, its prevalence is around 1% in Western Countries. Read More

Celiac disease (CD) is the most common autoimmune enteropathy worldwide. In CD, dietary gluten triggers a T cell driven small intestinal inflammation in a subset of genetically predisposed subjects, expressing the HLA DQ2 and/or DQ8 genes on their antigen presenting cells. HLA DQ2/DQ8 can bind gluten peptides after their prior modification by the CD autoantigen, tissue transglutaminase (TG2). Read More

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. Read More

HLA typing requests for association studies of immune-mediated diseases are often redundant and inadequate. We designed a series of meta-analyses to evaluate the accuracy of typing and distribution of HLA alleles predisposing to diseases, aiming at developing an app that can help doctors in choosing the most suitable molecular analysis. The first study was on celiac disease (CD) and HLA-DQ in children. Read More

Celiac disease (CD) is an autoimmune/inflammatory condition triggered by dietary gluten intake in genetically predisposed individuals. Though associations with MHC class II HLA-DQ2 or -DQ8 are the primary and necessary genetic predisposition for CD, >97% of genetically predisposed individuals never develop CD. Cytokines were measured in the serum of CD patients and controls. Read More

Human leukocyte antigen (HLA) genotyping has become a useful investigation in the diagnostic work-up of celiac disease (CD), with utility in risk stratification and screening. However, broad application of this technology has been hindered by the cost and time burden of conventional laboratory-based assays. We have developed and validated CD-loop-mediated isothermal amplification (CD-LAMP), a LAMP assay, which enables rapid identification of the signature CD risk genotypes, HLA-DQ2. Read More

Background: Kawasaki disease (KD) is a self-limited acute systemic vasculitis of unknown aetiology that predominantly affects infants and young children eventually associated with immunological abnormalities. Coeliac disease (CD) is an inflammatory autoimmune disease characterised by a permanent gluten intolerance, which affects genetically susceptible individuals of any age group, and can cause intestinal and systemic symptoms. Association of CD with KD has been previously described in a single study that disclosed a surprisingly high prevalence of CD in children with a history of KD. Read More

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.

Current diagnostic guidelines for celiac disease (CD) in pediatric patients require a duodenal biopsy if the IgA anti-tissue transglutaminase (tTG) is below 10x the upper limit of normal (ULN). Additional markers may enable a noninvasive diagnosis in this group. Serum intestinal-fatty acid-binding protein (I-FABP), a marker for intestinal epithelial damage, could be useful in this respect.

Background: Celiac disease (CD) occurs in subjects positive for HLA-DQ2 and/or DQ8 gene loci at any age following ingestion of gluten-containing food. An increased permeability of the mucosa allows interactions between gliadin macromolecules and genetic factors. It has been observed that Helicobacter pylori has the ability to modulate the integrity of the duodenal epithelium. Read More

Collagenous enteritis is an uncommon small intestinal injury pattern with unclear pathogenesis. While it has been speculated that collagenous enteritis represents a form of refractory celiac disease, recent clinical studies suggest a potential link to exposure to the antihypertensive medication olmesartan. Here we hypothesized that the pathogenesis of collagenous enteritis involves both genetic and environmental factors. Read More
