The coexistence of Down syndrome (DS) and celiac disease (CD) has been reported in many studies. In our study, we examined 82 children with DS aged 8 months to 8.6 years for the existence of CD using serological markers immunoglobulin A (IgA) and immunoglobulin G (IgG) transglutaminase antibodies, followed by follow-up determination of total IgA levels. In four children who were positive for one of the above-mentioned antibodies, enteric biopsy has been performed that showed absence of CD. Our findings raise doubt about the need for obligatory serological screening of children with DS aged <8 years.

Food protein-induced enterocolitis syndrome after involuntary gluten transgression in celiac children: A new increasingly common complication?

Among the possible adverse reactions to gluten, celiac disease, non-celiac gluten sensitivity, and IgE-mediated wheat allergy have been classically described. A non-IgE-mediated reaction similar to food protein-induced enterocolitis syndrome (FPIES) after inadvertent gluten ingestion in a celiac patient was recently reported. We present three children affected by celiac disease with exquisite control, including appropriate adherence to an exclusion diet, who suffered a severe adverse food reaction after unappreciated outdoor ingestion of gluten, meeting the criteria for a definitive diagnosis of FPIES.

Background: Median arcuate ligament syndrome (MALS) occurs due to extrinsic compression of the coeliac plexus, leading to postprandial and exercise-induced epigastric pain, nausea, vomiting, food fear and weight loss. Diagnosis can be challenging as up to 25% of the population have radiological compression. However, only 1% of the population have corresponding symptoms.

NOD-like receptors (NLRs) are a family of cytosolic pattern recognition receptors (PRRs) implicated in the innate immune sensing of pathogens and damage signals. NLRs act as sensors in multi-protein complexes called inflammasomes. Inflammasome activity is necessary for the maintenance of intestinal homeostasis, although their aberrant activation contributes to the pathogenesis of several gastrointestinal diseases.

Nowadays, the gluten-free diet (GFD) has become much more than the dietary treatment for celiac disease. Due to its presumed beneficial effects even in non-celiac subjects, it has become a new fashion statement and it is promoted by some healthcare professionals, social media and marketing strategists. On the other hand, regardless of a proper medical indication, a GFD may present side effects, such as poor palatability, high costs and socio-psychological adversities.

Article Synopsis
- The study investigates DNA methylation profiles of irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), celiac disease (CeD), and healthy controls (HC) to develop classifiers that can distinguish these GI disorders.
- Researchers analyzed blood samples from 315 participants and found significant differences in DNA methylation between disorders, especially between IBS & IBD and IBD & CeD.
- The classification models showed promising accuracy (AUC values ranging from 0.73 to 0.80), suggesting that blood-based DNA methylation biomarkers might effectively differentiate between these chronic gastrointestinal conditions.
