Aim: Aim of this study is screen of the large numbers of related genes of CD to find the key ones.
Background: Celiac disease (CD) is known as a gluten sensitive and immune system dependent disease. There are several high throughput investigations about CD but it is necessary to clarify new molecular aspects mechanism of celiac.
Methods: Whole-genome profile (RNA) of the human peripheral blood mononuclear cells (PBMCs) as Gene expression profile GSE113469 was retrieved Gene Expression Omnibus (GEO) database. The significant genes were selected and analyzed via protein-protein interaction (PPI) network by Cytoscape software. The key genes were introduced and enriched via ClueGO to find the related biochemical pathways.
Results: Among 250 significant genes 47 genes with expressed change above 2 fold change (FC) were interacted and the constructed network were analyzed. The network characterized by poor connections so it was promoted by addition 50 related nodes and 18 crucial nodes were introduced. Two clusters of biochemical pathways were identified and discussed.
Conclusion: There is an obvious conflict between microarray finding and the well-known related genes of CD. This problem can be solve by more attention to the interpretation of PPI ntwork analysis results.

Background&aims: Celiac disease (CD) and potential CD (pCD) are immune-mediated disorders triggered by the ingestion of gluten. In non-celiac gluten sensitivity (NCGS) neither allergic nor autoimmune mechanisms are involved. Relationships between NCGS and CD need to be further investigated.

Celiac disease is an autoimmune condition that affects approximately 1% of the worldwide community. Originally thought to be confined mostly to the small intestine, resulting in villous atrophy and nutrient malabsorption, it has more recently been implicated in systemic manifestations as well, particularly when undiagnosed or left untreated. Herein, the physical and psychological symptoms of celiac disease are described and explored.

The case involves a 63-year-old hypertensive man, taking antihypertensive medication (olmesartan) for the previous two years, who sought medical attention due to voluminous diarrhea, with several episodes per day and weight loss of 10 kg. He was submitted to a series of diagnostic procedures without elucidation and empirical treatment with unsuccessful outcome. After hospitalization for clinical stabilization and for presenting with duodenal atrophy, obtained by duodenal biopsy associated with negative markers for celiac disease, the patient was diagnosed with suspected olmesartan-induced enteropathy, showing rapid improvement of diarrhea after the drug was withdrawn, with weight regain in 6 months and normalization of the duodenal histological picture after 10 months.

Background And Aims: In coeliac disease, the clinical role of the urinary gluten immunogenic peptide is unclear. It has been suggested it can be a non-invasive marker of villous atrophy. Therefore, we present the largest cross-sectional clinical data in patients with coeliac disease to establish the diagnostic accuracy of the urinary gluten immunogenic peptide in identifying villous atrophy.

Following a gluten-free diet (GFD) is known as the main effective therapy available for celiac disease (CD) patients, which in some cases is not enough to heal all patients presentations completely. Accordingly, emerging researchers have focused on finding novel therapeutic/preventive strategies for this disorder. Moreover, previous studies have shown that celiac patients, especially untreated subjects, are at increased risk of developing viral and bacterial infections, which can become a challenge for the clinician.
