A new triad: sensitivity to aspirin, allergic rhinitis, and severe allergic reaction to ingested aeroallergens.

Increasing attention has recently been paid to a group of patients who experience anaphylaxis after ingestion of foods prepared with mite-contaminated wheat flour. We present three cases of this syndrome, which occurs more often in young adults with allergic rhinitis and/or asthma. We have observed an increased frequency of sensitivity to aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs), manifested as urticaria or angioedema, in patients with this condition.
