Abstract:
Oral allergy syndrome (OAS) is caused by cross-reactivity between certain pollens and plant foods, including vegetables, nuts, or fruits. Here, we experienced 2 cases of OAS patients associated with mugwort pollinosis without sensitization to Fagales. A 54-year-old female repeatedly experienced skin rashes, perioral edema, nasal obstruction after eating fresh vegetables (celery, lettuce, chicory, radish sprouts, ginseng, etc.). She had suffered from allergic rhinitis worsening in autumn for 5 years. Specific IgE (sIgE) titers to ragweed and mugwort were elevated to 54.1 and 24.9 kU/L, respectively. With regard to the allergen component of pollens, sIgE to Art v 1 (mugwort) and Amb a 1 (ragweed) were elevated to 21.9 and 36.1 kU/L, respectively. Birch sIgE (including Bet v 1 and Bet v 2) was not detected. A 35-year-old male suffered from abdominal pain, skin rashes after eating mango and kiwi. In addition, systemic allergic reaction developed after consumption of tomato and ginseng. He had chronic rhinitis. The sIgE levels to ragweed, mugwort, and tomato were elevated to 0.55, 6.39, and 0.78 kU/L, respectively. The sIgE test results were all negative for Amb a 1, Bet v 1, and Bet v 2 sIgE. Specific IgE levels to Art v 1, Art v 2 sIgE were 3.51 and 4.46 kU/L, respectively. Based on the history and sIgE test results, 2 cases OAS were related to mugwort. We experienced 2 cases of weed pollinosis related to OAS. Culprit foods of OAS can vary depending on their cuisine cultures.
