Abstract: | Food anaphylaxis is now the leading known cause of anaphylactic reactions treated in emergency departments, and wheat is one of the most common causes of anaphylaxis. Wheat is an important source of food worldwide. Wheat anaphylaxis is increasingly observed in our clinic. The purpose of this study was to describe the clinical features of wheat-induced anaphylaxis in 19 children for better elucidation of this disease. Children with severe reactions after ingestion of small amounts of wheat were referred to our clinic during a 4-year period. A detailed clinical history was recorded for each of the patients and a skin prick test was performed with wheat allergen extracts. The wheat-specific IgE and total IgE were measured. Grading of anaphylaxis episodes was performed according to a specific grading system. We identified 36 episodes of wheat anaphylaxis in 19 patients. All of the first attacks of wheat anaphylaxis occurred in the first-time ingestion. The most frequent manifestations of the reactions were skin and respiratory symptoms. In this study 78.9% of reactions were moderate and 21.1% of them were severe. All of our patients had positive skin prick tests to wheat. Mean total IgE level was 853.4 ± 455.27 IU/ml, and mean wheat-specific IgE was 70 ± 14.61 Ucs/ml. We conclude that wheat-induced anaphylaxis is a disease that is sufficiently severe, and. prevention of first wheat-induced anaphylaxis episodes is almost impossible. It would, however, probably be good practice to educate physicians to recognize the common clinical manifestations of this disease for early management. |
