Food Hypersensitivity Clinical Trial
Official title:
Tolererer Fiske- og Skaldyrsallergikere Fiskeolietilskud? Et Klinisk Studie
The purpose of this clinical study is to test whether patients with fish or shellfish allergy can ingest different types of fish oil supplements without having an allergic reaction. To achieve this, the recruited participants will be asked to: - provide a blood sample (used for Basophil Histamine Release Assay) - undergo a skin-prick-test - partake in multiple oral provocations These three tests will indicate the likelihood that the participants can consume fish oil supplements without adverse allergic reactions (See the detailed description for an explanation of the tests). The investigators will test the participants tolerance for three different types fish oil supplements: Fish oil, Cod liver oil, and krill oil.
The Basophil Histamine Release Assay is a test that indicates whether or not the immune cells of the participant reacts when it comes into contact with the fish oils. The skin-prick-test involves the participants having their skin exposed to the fish oils. This is done by first exposing a tiny needle to the given fish oil, and then pricking the needle into the skin on the forearm of the participant. In this way, the immune cells of the skin is exposed to the fish oils. If an allergic reaction occurs, the pricked skin will swell and turn reddish. During the oral provocation, the participant is asked to ingest small, but increasing, doses of the fish oils over a period of 2 hours. The provocation will end when either an allergic reaction occurs or the participant has ingested a total dose of 5 mL fish oil. ;
