Understanding The Immune Mechanisms Leading To Resolution Of Peanut Allergy

Summary
Food allergy affects up to 10% of children and rates are rising. The greatest rise has been in peanut allergy which is the commonest cause of life threatening reactions. Currently, there is no cure for food allergy. Management relies on food avoidance which is impossible to achieve. Recent deaths in children from food allergy highlight the need for an effective treatment. This project will examine what happens when you grow out of peanut allergy. New information will lead to possible cures.
Probiotic Prawn Oral Immunotherapy (ProPIT) For Treatment Of Prawn Allergy

Summary
A ‘curative’ food allergy treatment is needed to prevent deaths and improve care. We recently showed that probiotic peanut oral immunotherapy (PPOIT) was highly effective for treating peanut allergy. 82% of PPOIT treated children gained tolerance compared to 4% of the placebo group. We will now test the combined probiotic-food OIT approach for treating prawn allergy. If successful, we will have identified the first treatment for prawn allergy and a platform treatment for other food allergies.
Modified Peanut Allergen Combined With A Novel Dietary Adjuvant As A Cure For Peanut Allergy: A Randomised Controlled Trial

Summary
Peanut allergy is common and there is no cure. Current studies of peanut immunotherapy have shown the effects are not generally long lasting with many side effects. We plan to study a novel form of oral peanut immunotherapy using modified peanut and a dietary fibre (modified starch) supplement. We have evidence that modified peanut may work to desensitise patients with less side effects and that the diet supplement protects animals from developing food allergy.
Risk Factors For Food Allergy And The Allergic March To Asthma In Childhood: The HealthNuts Study

Summary
Food allergy appears to represent a second epidemic of allergic disease. It is not known why some children grow out of their food allergy or how food allergy in the first year of life impacts asthma and allergy in later childhood. HealthNuts is a large study of 5300 children that can answer these questions. HealthNuts visited children at ages 1, 4 and 6 and requests funding to re-visit them at age 10. Results will help prevent children developing food allergy, asthma and the allergic march.
BCG Immunisation To Prevent Allergy In Children: An Intervention Trial

Funding Amount
$1,187,260.00
Summary
There has been a dramatic rise in allergic diseases (asthma, eczema, food allergy) worldwide and particularly in Australia, with up to 30% of children affected. There is evidence from small studies that BCG immunisation has beneficial effects that prevent an allergic type immune response later in life. In a large randomised trial we will determine whether BCG at birth prevents allergic disease by monitoring eczema and food sensitivity in infancy, both of which predict an allergic predisposition.
Maternal Diet Rich In Eggs And Peanuts To Reduce Food Allergies: A Randomised Controlled Trial.

Summary
Food allergies now affect more than 1 in every 10 children. Recently, babies have been found to be at risk of developing a food allergy even before they start eating solid foods. We have discovered that baby immune responses can be improved by mothers eating more eggs during the first weeks of breastfeeding. Thus we are undertaking this research trial to determine whether mothers regularly eating more eggs and peanuts during pregnancy and breastfeeding will reduce food allergies in their babies.
Early Introduction Of Dietary Allergen To Reduce The Population Prevalence Of Infant Food Allergy

Funding Amount
$412,468.00
Summary
Australia has the highest recorded prevalence of childhood peanut allergy, a potentially life-threatening condition. New evidence shows introducing peanut into the diet in infancy can reduce the risk of developing peanut allergy in high risk infants, and allergy prevention guidelines now recommend giving peanut before 12 months. This study will evaluate how effective these guidelines have been in promoting earlier peanut introduction and reducing the population prevalence of peanut allergy.
A Population-based Longitudinal Assessment Of Early Life Vitamin D And Risk Of Food Allergy

Funding Amount

Summary
There has been a dramatic and unexplained increase in food allergy over recent decades. The increase in food allergy may relate to a concordant increase in early vitamin D insufficiency, however this hypothesis has never been directly tested. This project will use existing/funded samples from two NHMRC funded studies to conduct a detailed investigation of (i) the determinant and predictors of early life vitamin D insufficiency; and (ii) the association of vitamin D insufficiency and food allergy ....There has been a dramatic and unexplained increase in food allergy over recent decades.

Perinatal Exposure To Household And Environmental Toxins And The Risk Of Asthma And Allergic Disease Up To 25 Years

Funding Amount
$291,078.00
Summary
Perinatal exposure to household and environmental toxins may increase asthma and allergic disease risk. Adverse exposures in this critical developmental window may have a marked and prolonged effect on health. A birth cohort of high-allergy risk children will be used to investigate the effect of common chemical exposures on the risk of asthma and allergic disease up to 25 years. This evidence could be used to inform guidelines on common household chemical exposures
Functional Characterisation Of Novel Metabolites In Asthma And Identification Of New Biomarkers

Summary
Asthma is a chronic inflammatory disease of the airways that represents a major health burden. Severe asthma represents 10% of those suffering the disease and poses an urgent problem due to exacerbations and resistance to current therapies. We have conducted the first study of the metabolites that are altered in the airways of patients with severe asthma and identified functional metabolites and disease biomarkers. We now aim to assess the function of these molecules in asthma disease models.
