Results LSJ, a 13-years old Brazilian girl has complained of urticaria and asthma about 40 minutes after ingesting salty boiled beetroot on a meal. She had a previous history of wheezing until she was five years old. Seric-specific IgE to beetroot and other foods were negative, as well as to latex, bee, wasp and ant. She was sensitized only to house dust mite. Boiled and raw beetroot prick to prick were also negative (histamine resulted 4mm) but a food challenge with boiled beetroot resulted positive after 30 minutes with generalized hives, throat tightness and bronchospasm. Symptoms were controlled with intramuscular epinephrine, inhaled beta-2-agonists and intravenous corticosteroids. She was advised for a diet free of beetroot and she has had no symptoms for the last 8 months.
