Asymptomatic gastroduodenal anisakiasis as the cause of anaphylaxis.

摘要

A great number of parasites have been reported in fish, but only a few of them are capable of infecting human beings. Anisakiasis or anisakidosis is caused by sea nematodes of the genus Anisakis, with the main implicated species being Anisakis simplex. Infection with Anisakis causes a wide spectrum of clinical manifestations, ranging from symptoms related to the upper and occasionally lower digestive tract to allergic manifestations, mainly urticaria and anaphylaxis. We report a case of asymptomatic gastroduodenal anisakiasis presenting as severe anaphylaxis.
