[Allergy to sesame seeds].

Two cases of allergy due to the ingestion of sesame seeds are described. Sesame seeds must be considered to be an extremely potent allergen. They cause severe allergic reactions with pruritus, generalized erythema, angio-oedema of the uvula, clinical shock and wheezing. Such reactions are usually preceded by milder ones ("shock fragments"), which, if promptly and correctly diagnosed and treated, may prevent clinical progression of symptoms. Therefore, it is important to recognize hypersensitivity to sesame seed without delay so that the patient may eliminate the causative agent and use suitable medication in the event of a dietary indiscretion. Sesame oil ingestion may not produce any similar reaction. The consumption of sesame seeds is increasing throughout the world. This suggests that the incidence of hypersensitivity to sesame seed will probably increase by the same proportion.
