Immunochemical reactivity to peanuts and nuts in allergic individuals

Project Code: T07011

30/11/2002

The aim of this three-year project was to establish whether there is a difference in allergic reactions to peanuts and other nuts between adults and young children, and if so, to determine the reason for this.

The researchers found that children developed allergic reactions to peanut first, usually before the age of 2. From the age of 2 onwards they go on to develop allergic reactions to other nuts as they were exposed to them, and by 10-15 years old, most of those seen reacted to more than one nut. Children had milder reaction than adults did.

The researchers have developed a management plan for reducing further allergic reactions in nut allergy sufferers. They have also recommended that those who are allergic to one type of nut should avoid ingestion of others, and that children with nut allergy should be assessed periodically for the development of multiple allergies.
