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

$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.
In Vitro And In Vivo Assessment Of The Funhaler -an Innovative Therapeutic Device For Children

Summary
Aerosol therapy is the most effective form of treatment for children with respiratory diseases such as asthma. While optimising aerosol delivery systems has an important role in increasing the efficacy of asthma therapy, ensuring patient compliance is often the most difficult part of the clinician's role, particularly in the paediatric age group. An innovative small volume spacer device (Funhaler) developed by a West Australian company (InfaMed, Ltd) may help overcome this problem. The Funhaler ....Aerosol therapy is the most effective form of treatment for children with respiratory diseases such as asthma. While optimising aerosol delivery systems has an important role in increasing the efficacy of asthma therapy, ensuring patient compliance is often the most difficult part of the clinician's role, particularly in the paediatric age group. An innovative small volume spacer device (Funhaler) developed by a West Australian company (InfaMed, Ltd) may help overcome this problem. The Funhaler incorporates a spinning toy attached to the outside of the spacer. The toy is activated when the patient breathes through the spacer. The device has been designed to encourage children to co-operate when their asthma therapy is being delivered. The Funhaler is currently in the late development stage. We propose, firstly, to carry out in vitro assessments of drug delivery from the Funhaler compared to the two most widely available small volume spacers: the Aerochamber Plus (Trudell, Canada) and the Breath-A-Tech (Scott-Dibben, Australia). These assessments will be carried out to meet the standards of regulatory bodies worldwide (including the FDA). Secondly, we propose to perform extensive in vivo studie: filter studies to assess drug delivery to the patient; deposition studies to measure drug deposition in the lungs; and a pilot clinical trial to assess the efficacy of the device during medium to long-term use in children aged 2-8 years.Read moreRead less
Maternal Gut Microbiome During Pregnancy Influences Offspring Atopy And Asthma.

Summary
Allergic diseases such as food allergy and asthma have increased significantly as our exposure to bacteria has reduced. Many studies have explored exposure to bacteria in early life but few have examined the maternal bacteria we are exposed to while we develop in the womb. New studies indicate that we are exposed to many different components of our mothers gut bacteria and this might change our developing immune system and determine whether or not we get diseases like food allergy and asthma.
The Clinical Utility Of Small Airway Function Tests In Paediatric Respiratory Disease

Funding Amount
$64,631.00
Summary
Respiratory disease is an important child health issue with long term implications into adulthood. The evaluation of small airways involvement in disease processes, using an accurate sensitive measures of function, such as forced oscillation technique and multiple breath washout, potentially facilitates not only early detection of disease, but instigation of earlier treatment, better assessment of response to treatment, and ultimately better outcome.
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.
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.
Genetic And Environmental Factors And Early Lung Problems Can Be Related To Allergy And Poor Lung Development In Preschool Age Children

Funding Amount
$122,032.00
Summary
This important new collaboration between the Murdoch ChildrenÍs Research Institute and Barwon Health explores the impact of early lung development on longer term respiratory health. It utilises a newly validated, accurate and safe technique to measure lung function in young babies and children. Data on environmental factors and lung function will help us explore the risk factors for the development of allergy, asthma and lung infections in early life.
