• Coeliac disease is a genetically-determined chronic inflammatory intestinal disease induced by an environmental precipitant, gluten.
• Patients with the disease might have mainly non-gastrointestinal symptoms, and as a result patients present to various medical practitioners.
• Epidemiological studies have shown that coeliac disease is very common and affects about one in 250 people.
• The disease is associated with an increased rate of osteoporosis, autoimmune diseases, and malignant disease, especially lymphomas.
• The mechanism of the intestinal immune-mediated response is not completely clear, but involves an HLA-DQ2 or HLA-DQ8 restricted T-cell immune reaction in the lamina propria as well as an immune reaction in the intestinal epithelium.
