Abstract
- Peanut allergy is a significant health problem because of the potential severity of the allergic reaction, the life-long nature of the allergic hypersensitivity, and the ubiquitous use of peanut products. Peanut is one of the most common foods causing serious anaphylactic reactions. Three major peanut allergens, Ara h 1, Ara h 2, and Ara h 3 are 64.5, 17.5, 14 kd glycoproteins belong to the vicillin, conglutin, and glycinin families of seed storage proteins, respectively. We report a case of anaphylaxis induced by peanut with generalized edema, skin rash, dyspnea, hypotension, syncope after accidental peanut ingestion of a 33-year-old man. The diagnosis could be confirmed as peanut-induced anaphylaxis on the basis of prick test, open patch test, MAST, and T cell proliferation assay in addition to history.
