Summary
Anaphylaxis is a serious allergic reaction that is rapid in onset and may cause death. This award will support research projects that aim to improve both the emergency care of this condition and subsequent immunotherapy (desensitisation) for people who experience anaphylaxis to insect sting. It will also support research to better understand anaphylaxis to antivenoms, which is a major problem worldwide, and to thus improve the treatment of snake, scorpion and spider envenoming.
Population Prevalence And Environmental-genetic Predictors Of Food Allergy In An Infant Cohort

Summary
This study will measure which children are at greatest risk of food allergy. We plan to recruit 5000 children to test for food allergies, as well as asking a range of questions on different lifestyle factors such as diet and history of allergies . If positive, participants will be invited to a hospital clinic for tests and treatment. This will allow us to describe the epidemiology of food allergy, and assist the development of better services for those with food allergy in the community.

Summary
An allergy to nuts is estimated to affect 1% of the population and peanuts are the major cause of fatal food-induced anaphylaxis. Five deaths occurred in the UK in 1993 which attracted media attention to the gravity of this problem. Proteins in the nut trigger a massive immunological reaction that causes the body to go into anaphylactic shock in which all the major body systems shut down. Nut allergy usually presents in infancy and persists indefinitely.

Five deaths occurred in the UK in 1993 which attracted media attention to the gravity of this problem. Proteins in the nut trigger a massive immunological reaction that causes the body to go into anaphylactic shock in which all the major body systems shut down. Nut allergy usually presents in infancy and persists indefinitely. As nuts are used in a wider and less visible range of food products, sensitisation is increasing and occurring earlier. It has been proposed, wrongly, that peanut (groundnut) allergic patients do not suffer from allergy to tree nuts (hazel, almond, Brazil, walnut). However a British survey of 1250 patients suffering from peanut anaphylaxis revealed that 50% of people with peanut allergy are also allergic to other nuts confirming our own clinical observations. At present, unlike insect venom allergy, grass pollen allergy and house dust mite allergy, there is no preventative treatment available. We plan to explore peanut allergy and investigate cross-reactivity between peanuts and major tree nuts to attempt to identify an allergen(s) that could explain the molecular nature of the allergy and offer approaches to immunotherapy. This information is necessary if we are to achieve safe and effective allergy shots for patients with this life long and life-threatening allergy as well as assisting in the development of better diagnosticRead moreRead less
