Summary
Asthma is the most common chronic disease complication during pregnancy. By improving asthma management we have reduced asthma exacerbations by 50% during pregnancy and their babies suffered less often from bronchiolitis in the first year of life, which can be a life threatening infection. As bronchiolitis also promotes the development of asthma we want to investigate whether better asthma management in pregnancy leads to less lung inflammation and better lung function in the children.
Extending The MIS BAIR Randomised Trial Of BCG To Prevent Childhood Allergy And Infection

$939,504.00
Summary
BCG (used till recently to prevent tuberculosis) is a potential low cost and readily available vaccine which could reduce the rates of allergy and infection in Australian children. We propose to extend our existing NHMRC-funded trial, which studies whether BCG vaccinatinon given at birth prevents the development food allergy, eczema and infection in the 1st year of life, to see if this effect continues until 5yrs of age. At this age, we can also see if BCG vaccination at birth prevents asthma.
Prevention Of Asthma In Young Children Via Immunostimulation

Summary
Persistent asthma is a major problem for Australia yet none of the current therapies do more that control the condition. The long-term solution is to prevent asthma from progressing to the persistent form. The major risk factors are: family history, early allergy and recurrent severe lower respiratory infections (sLRI) in the early life. We will conduct a randomized clinical trial to prevent sLRI using a novel bacterial-derived immunostimulant in infants at high risk of developing asthma.
Maternal Carriage Of Prevotella During Pregnancy Influences Offspring Innate Immune Responses And Asthma At Age 7

Funding Amount
$916,798.00
Summary
This project will investigate the relationship between the bacteria a mother carries in her gut during pregnancy and her baby’s risk of developing allergic disease and asthma. We will investigate underlying immune pathways and conduct experiments in mice to determine whether inoculating mothers with a specific type of bacteria known as Prevotella could be used to prevent food allergies and asthma in the offspring.
Risk Factors For Food Allergy And The Allergic March To Asthma In Childhood: The HealthNuts Study

Funding Amount
$1,876,796.00
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
Funder
National Health and Medical Research Council
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.
A New And Effective Approach To Reversal Of Allergic Airways Inflammation By Turning Off Allergic Responses

Funding Amount
$393,514.00
Summary
Inflammatory diseases like asthma develop from misdirected immune responses. The ultimate goal of therapeutic strategies is to remove or inactivate the cells that cause inflammation while leaving other cells, for example, those required for protection from infectious diseases and tumours, unaffected. Here we propose to test a new way of turning off the inappropriate immune reaction with the goal of preventing or reversing asthma.
Does N-3 LCPUFA Supplementation In Pregnancy Reduce Asthma And Allergies In School Age Children?

Funding Amount
$443,833.00
Summary
We will determine whether supplementing the diets of pregnant women with fish oil can have long term effects on the development of the childÍs immune system and reduce the prevalence of asthma and allergies at early school age. The outcomes of our project will inform nutritional guidelines for pregnant women and, if successful, has the potential to significantly lower the costly burden of childhood asthma and allergies to families and the healthcare system.
What Are The Lifetime Clinical Predictors And Risk Factors For Multiple Phenotypes Of Adult Asthma, COPD And Sleep Disordered Breathing? Following Up The TAHS Cohort From 1st To 6th Decade

Funding Amount

Summary
Breathing gets impaired and impact on the productivity and quality of life when chronic respiratory diseases rise with ageing. Adult chronic respiratory diseases are major causes of illness and death but there are still many gaps in knowledge on how best to prevent and manage these diseases. The proposed program will provide evidence to guide health policy and clinical management of these diseases. These original findings will be of great importance both nationally and internationally.
Localised Airway Reactivity As A Determinant Of Asthma Control And AHR

Funding Amount
$306,562.00
Summary
Asthma morbidity and mortality remain high, with drug cost, days lost from school and work. This may be due to severe asthma in which control cannot be attained. This may be due to localised regions of lung that remain persistently responsive to inhaled irritants. We will examine the location and size of these regions using 3-dimensional ventilation scanning. The potential importance of our findings is in providing a basis for improving treatment in resistant, severe asthma.
