Summary
There is a strong association between allergy and asthma. This association been almost universally assumed to be causative. However, recent evidence suggests an alternative explanation ie., that the abnormal epithelium in asthma allows or facilitates sensitization to airborne allergens. This project will test this alternative hypothesis using human lung tissue and an animal model.
Systems Biology Of Asthma Development In Early Childhood

Summary
Recent studies have established that both human genetic susceptibility and viral infections during early childhood are important drivers of asthma development. It has also been noted that asthmatics’ airways are colonized with different bacteria to non-asthmatics. In this project we will examine how genetic susceptibility and interactions between bacteria and viruses in children's airways promote the development of allergy and 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.

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
Longitudinal Characterization Of Respiratory And Immune Development From Birth To Adulthood In The Perth Respiratory Birth Cohort

Summary
The Perth Respiratory Birth Cohort Study began in 1987 and has assessed 253 children before birth and at follow-up at 1, 6 & 12 months, and 6, 11 & 18 years of age. The study has resulted in 63 publications and achieved consistent international prominence. The proposed study of the cohort at 24 yrs aims to determine the respiratory and immunological status of the cohort as young adults. This follow-up is essential to determine how early risk factors affect respiratory outcome in young adults.
Improving Lung Health Of Indigenous Children, Through Identifying Interventional Targets From Long Term Follow-up Studies And Preventive Strategies

Summary
Long term consequences of respiratory disease among Indigenous children are a public health issue. Studies included in this research program will provide new data and broaden our understanding on clinical predictors that significantly impact on lung health in Indigenous children. The studies will also direct future interventions and management pathways. This research will also contribute to improved asthma management, prevent uptake of smoking contributing to an overall improvement in health.
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.
Mechanisms Of Induction And Progression Of Childhood Asthma: Investigations In A Mouse Model

National Health and Medical Research Council
Funding Amount
$517,586.00
Summary
This project investigates how certain respiratory viral infections in very young children might predispose to developing asthma, and how inflammation in the airways in asthma might then worsen. The experimental work, which will use unique mouse models developed in the laboratories of the chief investigators, will focus on changes in genes that control the pattern of immune response to allergens and that regulate the progression of inflammation.

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.
