Chicken meat induces oral allergy syndrome: a case report
1Department of Allergology and Clinical Immunology, University Clinic, Faculty of Medicine, Pamplona, Navarra, Spain.
Background:
The term oral allergy syndrome (OAS) describes an IgE-mediated reaction that takes place minutes after ingestion of some food to which the organism is previously sensitised. The clinical manifestations are typically localized to the mouth and throat. Oral allergy syndrome is commonly elicited by fresh fruits and vegetables, especially in subjects with hypersensitivity to pollens.
Methods:
We report a patient with OAS following intake of chicken meat. We performed (1) skin prick test to chicken meat, egg, milk, and wheat and to common inhalants, (2) determination of serum specific IgE, (3) histamine release test, and (4) in vitro antigen-specific production of sulphidoleukotrienes and challenge test with chicken meat.
Results:
Skin prick test was positive only for chicken meat. The patient had serum specific IgE, positive histamine release test, and specific production of sulphidoleukotrienes to chicken meat. We confirmed these findings by means of the challenge test.
