Oral Tolerance Induction in Adults with Allergy to Gluten-Containing Cereals: A Case Report

Abstract

Cereals are the main source of energy, protein, B vitamins and minerals for the world population. Due to its ease of harvest and its resistance, wheat is the most cultivated and consumed cereal worldwide. Allergic reactions to wheat are rare, their prevalence in pediatric patients varies from 0.5-1.0%, being more frequent in areas such as Japan and northern Europe and in adults, although less frequent, they have also been described. The prognosis of allergy to wheat in childhood is favourable, but there are more severe cases that remain allergic until adolescence or adulthood; in these cases, oral tolerance induction (OTI) can be considered as a therapeutic alternative to the avoidance diet. We presented a case of 32-year-old patient with the onset of wheat allergy in adulthood with severe anaphylaxis. To date, there is no report of OTI with wheat in allergic adult patient, similar to the one described in this report.
