Bronchial asthma induced by chick pea and lentil

Abstract

Allergic reactions to legumes through inhalation have rarely been described. We report the case of a 20-year-old man who experienced asthmatic attacks when exposed to the steam from cooking either chick pea or lentil. Type I hypersensitivity to the antigens in these legumes was demonstrated by means of immediate skin reactivity, histamine release tests, RAST and RAST inhibition. Specific bronchial challenges with the heated (75 degrees for 30 min) extracts of chick pea and lentil elicited isolated immediate responses.
