title: [Nonspecific anaphylactoid reaction in low IgE patients].
abstract: We reported two cases of anaphylactoid reaction caused by ranitidine and alprostadil. We suggest that these anaphylactoid reactions are nonspecific reactions which are observed in low IgE patients, because plasma IgE was still low 6 weeks after allergic reaction and these drugs have not been given to them before and eosinophilic and basophilic cells showed no change at all. We have to consider that there is a high risk of allergic reaction during general anesthesia, because many drugs are injected intravenously during general anesthesia.
