Celiac disease occurs in about 1% of the population worldwide, although most people with the condition are undiagnosed. It can cause a wide variety of symptoms, both intestinal and extra-intestinal because it is a systemic autoimmune disease that is triggered by dietary gluten. Patients with coeliac disease are at increased risk of cancer, including a twofold to fourfold increased risk of non-Hodgkin’s lymphoma and a more than 30-fold increased risk of small intestinal adenocarcinoma, and they have a 1.4-fold increased risk of death.
The abnormal immunological response elicited by gluten-derived proteins can lead to the production of several different autoantibodies, which affect different systems.
Several additional studies in extensive series of coeliac patients have clearly shown that TG2A sensitivity varies depending on the severity of duodenal damage, and reaches almost 100% in the presence of complete villous atrophy (more common in children under three years), 70% for subtotal atrophy, and up to 30% when only an increase in IELs is present. (IELs: intraepithelial lymphocytes)
Since 1990, the understanding of the pathological processes of CD has increased enormously, leading to a change in the clinical paradigm of CD from a chronic, gluten-dependent enteropathy of childhood to a systemic disease with chronic immune features affecting different organ systems. (...) atypical symptoms may be considerably more common than classic symptoms
In addition, the presence of intraepithelial lymphocytosis and/or villous atrophy and crypt hyperplasia of small-bowel mucosa, and clinical remission after withdrawal of gluten from the diet, are also used for diagnosis antitransglutaminase antibody (tTGA) titers and the degree of histological lesions inversely correlate with age. Thus, as the age of diagnosis increases antibody titers decrease and histological damage is less marked. It is common to find adults without villous atrophy showing only an inflammatory pattern in duodenal mucosa biopsies: Lymphocytic enteritis (Marsh I) or added crypt hyperplasia (Marsh II)
A lack of symptoms and/or negative serological markers are not reliable indicators of mucosal response to the diet. Furthermore, up to 30% of patients continue to have gastrointestinal symptoms despite a strict GFD.122,124 If adherence is questioned, a structured interview by a qualified dietitian can help to identify both intentional and inadvertent sources of gluten.
Presentation of CD with malabsorptive symptoms or malnutrition is now the exception rather than the rule.
It is necessary to consider that oats include many varieties, containing various amino acid sequences and showing different immunoreactivities associated with toxic prolamins. As a result, several studies have shown that the immunogenicity of oats varies depending on the cultivar consumed. Thus, it is essential to thoroughly study the variety of oats used in a food ingredient before including it in a gluten-free diet.
Furthermore, seronegativity is more common in coeliac disease patients without villous atrophy (Marsh 1-2 lesions), but these ‘minor’ forms of coeliac disease may have similar clinical manifestations to those with villous atrophy and may show similar clinical–histological remission with reversal of haematological or biochemical disturbances on a gluten-free diet (GFD).
Gluten comprises two different protein types, gliadins and glutenins, capable of triggering disease.
Similar proteins to the gliadin found in wheat exist as secalin in rye, hordein in barley, and avenins in oats and are collectively referred to as "gluten." Derivatives of these grains such as triticale and malt and other ancient wheat varieties such as spelt and kamut also contain gluten. The gluten found in all of these grains has been identified as the component capable of triggering the immune-mediated disorder, coeliac disease.
