Wheat induced urticaria.
Wheat is widely consumed all over India in various forms--flour, daliya, maida, suji and wheat bran. Very few cases of wheat induced urticaria have been reported. This may be due to unusual features of wheat related hypersensitivity. A 35 year old female presented to us with history of chronic urticaria and angioedema. History revealed correlation between wheat intake and urticaria episodes. Prick testing was done with wheat antigen in the standard series and derivatives of raw wheat. Normal saline and histamine were used as controls. Prick testing was positive. Oral challenge induced urticaria within half an hour. This report discusses clinical features of wheat related hypersensitivity.
