Anaphylaxis after ingestion of sharon fruit

Abstract

Background: The sharon fruit is the edible fruit of the persimmon tree (Diospyros kaki) which belongs to the Ebenaceae family. There are few references of allergic reaction to this fruit. We introduce a case of a 33-years old man with a anaphylactic reaction immediately after ingestion of sharon fruit.

Methods: Skin prick test (SPT) were performed by prick by prick with sharon fruit, legumes, vegetables, and fresh fruit. The test was considered positive when the average diameter of the wheal was > 3 mm. Serum-specific IgE was identified with use of the EIA, and SDS-PAGE Immunoblotting.

Results: The skin by prick test with sharon fruit was positive in our case, and negative in five controls patients. Specific IgE in patient serum, assayed by EIA was positive for sharon fruit, but the results of immunoblotting were non-specific.

Conclusion: We have introduced a cause of anaphylaxis by sharon fruit that suggest an IgE mediated hypersensitivity reaction.
