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.
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.
Investigation Into Host Susceptibility And Immune Responses In Young Children With Acute Wheezing Due To Human Rhinovirus Group C Infection

Funding Amount
$682,711.00
Summary
We recently made the surprising discovery that a new viral group, human rhinovirus group C (HRV-C), causes the majority of acute asthma in children. We also found that it causes half of the acute wheezing attacks in younger children, and is the only respiratory virus associated with allergy. So, HRV-C may be the key to the relationship between allergy and asthma. The planned project will focus on whether young children who wheeze with HRV-C have related defects in their immune system.
Characterization Of Cellular Inflammatory Responses Underlying Acute Viral Bronchiolitis In Infants

Funding Amount
$583,224.00
Summary
This project seeks to characterize the inflammatory mechanisms triggered during severe respiratory virus infections that result in hospitalization of infants. These are associated with later development of asthma. We aim to identify new molecular targets for anti-inflammatory drug development, with the long term goals of improving treatment for acute disease, and prevention of subsequent asthma.
The Relationship Between Maternal And Infant Dietary Intake Of Fermentable Fibre, Gut Microbiota, Short Chain Fatty Acids And Allergic Disease And Asthma: A Population-derived Birth Cohort Study

Funding Amount
$871,700.00
Summary
The proposed study will involve the Barwon Infant Study (BIS) cohort of 1074 infants to provide the first systematic investigation of the hypotheses that the epidemic of allergic disease and asthma in many parts of the world relates to the paucity of fermentable fibre in the modern diet, and that the protective effect of fermentable fibre is mediated by changes in the organisms that colonise the gut and the metabolites that they produce.
Multi-centre, Multi-disciplinary Study Using A Systems Biology Approach To Investigate Immunomodulation In Children With Acute Wheeze

Funding Amount
$1,895,107.00
Summary
The concept that immunomodulation using naturally-occurring bacterial agents can treat asthma has reached international prominence. This is backed by strong epidemiologic and clinical trial data. However, detailed knowledge of the immunological mechanisms involved is essential to allow more focused therapeutic agents to be developed. The proposed multi-disciplinary immunomodulation study in 200 children aims to provide this essential information using an advanced systems biology approach.
A POPULATION-BASED COHORT INVESTIGATION OF LUNG FUNCTION IN RELATION TO EARLY LIFE LOWER RESPIRATORY TRACT ILLNESS AND AEROALLERGN SENSITISATION

Summary
Infancy appears to be the critical developmental window during which important alterations in lung structure and function develop. In this study we will assess how early lung function evolves in relation to potential insults such as lower respiratory tract infections and allergic inflammation. These are the mechanisms by which asthma is thought to develop. We will use exciting new lung function tests to evaluate lung function abnormalities associated with peripheral dysfunction characteristic of ....Infancy appears to be the critical developmental window during which important alterations in lung structure and function develop. In this study we will assess how early lung function evolves in relation to potential insults such as lower respiratory tract infections and allergic inflammation. These are the mechanisms by which asthma is thought to develop. We will use exciting new lung function tests to evaluate lung function abnormalities associated with peripheral dysfunction characteristic of chronic airway disease such as asthma.Read moreRead less
Early Environmental Determinants Of Pancreatic Islet Autoimmunity: A Pregnancy To Early Life Cohort Study In Children At Risk Of Type 1 Diabetes

Summary
The doubling in incidence of type 1 diabetes in children over the last 20 years may be explained by our modern environment, including excessive weight gain in pregnancy and early life, inadequate dietary omega- 3 fatty acids or vitamin D, or viral infections. We therefore aim to study children with a family member with type 1 diabetes from the pregnancy and through early childhood to determine the effects of the environment on their risk of developing type 1 diabetes .This will lead to strategie ....The doubling in incidence of type 1 diabetes in children over the last 20 years may be explained by our modern environment, including excessive weight gain in pregnancy and early life, inadequate dietary omega- 3 fatty acids or vitamin D, or viral infections.

Understanding White Matter Injury In Term-born Children With Cerebral Palsy

Funding Amount
$193,863.00
Summary
The type of brain injury in cerebral palsy varies. In some children the brain develops abnormally in early pregnancy; others have a stroke or suffer from lack of oxygen around the time of birth. Little is known about the group of children born at term who have damage to the brain’s white matter, a pattern more typical of premature birth. This project will explore brain imaging, potential risk factors, and clinical outcomes for these children to identify possible causes and prevention pathways.
Neurobehaviour Between Birth And 40 Weeks In Infants Born

Funding Amount
$832,215.00
Summary
Very preterm infants (born at <30 weeks’ gestation) are at risk of long term developmental problems with 50% having cognitive, motor or behavioural problems. This study will examine, for the first time, neurobehavioral development of very preterm infants from birth so that we can describe neurobehaviour for a given gestation from birth to term equivalent age, and explore how it relates to brain growth or injury and to neurodevelopmental outcome at two years’ corrected age.
