Abstract

Background and objectives: Mugwort pollen is one of the major causative allergens in this country. There have been a few reports suggesting a significant association between mugwort pollen and food allergens. The aim of this study was to evaluate the allergenic relationship between mugwort pollen and food allergens based upon skin prick tests. Material and method: Of 2,909 allergy patients who had been skin tested to identify causative allergens at the Allergy Clinic of Ajou University Hospital, 471 patients sensitized to mugwort, ragweed, or Hop Japanese pollens on skin prick test (2+ of A/H ratio) were enrolled for this study. Positive rates to common inhalant or food allergens and their allergenic relationships with other pollens or food allergens were analyzed based upon skin prick test results. RESULTS: The positive rates (2+ of A/H) to nettle, rye grass, Bermuda grass, birch, and alder pollens were significantly higher in those sensitized to mugwort pollen than in those of negative responders (p<0.05, respectively). In regard to food allergens, positive rates to celery (15.3%) and carrot (14.5%) were significantly higher in patients sensitized to mugwort pollen (p<0.05, respectively). Significant association was noted between mugwort pollen and celery allergen (p< 0.05). CONCLUSION: Positive response to mugwort pollen can be associated with celery and carrot sensitivity on skin prick tests.
