[New horizons of gluten sensitivity studies].

Gluten sensitivity may be a cause of gluten-sensitivity celiac disease (GCD). Some gluten-sensitive subjects may have symptoms of GCD, but lack its characteristic changes in the small bowel mucosa (SBM) and a gluten-free diet results in the disappearance of clinical symptoms of GCD. If there is no gluten allergy, the concept "gluten intolerance (GI) unassociated with celiac disease" is applicable in these cases. There is an increase in the prevalence of GCD and GI, which is associated with the use of gluten in food industry to improve the taste and energy density of foods and with the damaging effect of viruses and bacteria on enterocyte membranes, thereby facilitating the penetration of gluten through SBM. The paper gives an update on progress in the diagnosis of GCD and GI and on prospects for designing gluten-free cereals.
