In this study, we investigated the role of mannose-binding lectin (MBL) in celiac disease, by performing genotype analysis for the three point mutations in the first exon of the gene in 117 Italian celiac patients (characterized by flat biopsy and positive for anti-endomysium antibody and human transglutaminase antibodies) and 130 pan-ethnic healthy controls. The frequency of homozygous mutant 0/ 0 was significantly higher in the 117 Italian celiac patients (0.13) than in the 130 pan-ethnic healthy controls (0.05; P=0.0405). An increased frequency of homozygous 0/0 allele was found among patients with celiac disease compared with controls. These results suggest an involvement of MBL in the pathophysiology of celiac disease.

Background: Celiac disease (CD) is a systemic disorder characterized by an enteropathy of highly variable clinical expression, in which the relationship with oral pathology has not yet been fully elucidated. We aimed to update the current knowledge on oral manifestations in CD, to identify evidence gaps and to point out future research lines.

Material And Methods: PRISMA-ScR guidelines were followed.

Introduction: Non-Celiac Gluten Sensitivity (NCGS) is a common disorder characterized by symptoms resembling those of irritable bowel syndrome. In recent years there has been progress in the understanding of the pathogenic pathways and data suggest that NCGS has a distinct immunological profile that differs from celiac disease (CeD). This has fostered the search for a specific biomarker of NCGS.

Purpose Of Review: Celiac disease (CeD) is a chronic autoimmune disorder of the small intestine triggered by gluten ingestion in genetically predisposed individuals. The cornerstone of CeD management remains a strict adherence to a lifelong gluten-free diet (GFD), although such a dietary restriction can lead to an altered quality of life and may not be easy to follow for many patients. These challenges highlighted the need for alternative therapies.
