It is well known that patients with latex allergy have cross-reactions to various fruits, which is called a latex fruit syndrome. We report four cases with latex allergy followed by anaphylaxis to chestnut. They are all nurses of our hospital, who has personal history of atopic diseases. There were varieties in the methods of processing chestnut, presence of epicutaneous contact to chestnut, and clinical courses among the cases. All cases had positive skin prick test reactions while only two cases showed specific IgEs measured with AlaSTAT to chestnut. This fact suggests that we have to warn the risk of anaphylaxis even if one had not shown a serum specific IgE. We could follow the clinical courses and study specific IgEs to chestnut and latex in the two cases for more than two years. The titer of specific IgE was increased in the one, who could not avoid eating chestnut and contact to latex, while it was decreased in the other who could avoid the exposure to the antigens. Hevein is one of the panallergens among latex and related fruits. We studied specific IgEs to hevein on these four cases and 12 normal controls. The results showed that the former had significantly higher values of sIgEs to hevein compared to the latter (p < 0.05). We conclude that a patient with latex allergy has a high risk of contact urticaria or even anaphylaxis to the related fruits such as chestnut so that we recommend the patient with latex allergy to avoid them.
