Summary
Classification of lifetime phenotypes of obstructive lung disease allows investigation of the effect of environmental and genetic influences on specific phenotypes along with the interactions between them. Through improved phenotyping ,the currently inconsistent relationships between asthma and COPD and their associations with genetic and environmental factors may become clearer.
Regulation Of Inflammatory And Epithelial Responses In An Experimental Model Of Chronic Human Asthma

Summary
This project examines how chronic inflammation and scarring develop in the walls of the airways in asthma. The particular role of allergic mechanisms and of specific types of cells that are involved in allergic inflammation will be tested, using a much-improved mouse model of asthma. In this experimental model, which was developed by the investigators, sensitised mice are chronically exposed to low concentrations of aerosolised egg white protein. The proposed studies will involve comparisons wit ....This project examines how chronic inflammation and scarring develop in the walls of the airways in asthma. The particular role of allergic mechanisms and of specific types of cells that are involved in allergic inflammation will be tested, using a much-improved mouse model of asthma. In this experimental model, which was developed by the investigators, sensitised mice are chronically exposed to low concentrations of aerosolised egg white protein. The proposed studies will involve comparisons with animals that are genetically deficient in their ability to produce certain inflammation-related molecules, as well as with mice treated with antibodies to block the action of other such molecules.Read moreRead less
The Relationship Between Airborne Particle Exposure, Incident Respiratory Symptoms And Decline In Lung Function

Summary
Air pollution has been consistently identified as the environmental health problem of greatest concern to the general public in Australia. Yet hard evidence of adverse health effects from air pollution in Australian cities and towns is limited to date. It has been estimated that high levels of particles in urban air could be responsible for as many as 2,400 deaths nationally, costing approximately $4,300 million each year. This study will follow two groups of young Melbourne adults recruited som ....Air pollution has been consistently identified as the environmental health problem of greatest concern to the general public in Australia. Yet hard evidence of adverse health effects from air pollution in Australian cities and towns is limited to date. It has been estimated that high levels of particles in urban air could be responsible for as many as 2,400 deaths nationally, costing approximately $4,300 million each year. This study will follow two groups of young Melbourne adults recruited some years ago for studies of respiratory health. They will be a sent a questionnaire by mail and invited back to our laboratory for breathing tests. We will obtain routinely collected air quality data and measure fine particles < 2.5 thousandths of a mm in outdoor air. A subgroup of 100 subjects will also participate in some measurements of indoor air pollution. The analysis will look for relationships between particles in the air, new symptoms and changes in lung function over time. Comparisons will also made with other centres doing a very similar study in Europe. Reviews commissioned by the National Environment Protection Council have highlighted the lack of Australian data to assist in setting standards for particulate air pollution. The proposed study would provide some of the necessary local data and assist in the development of new health based environmental protection measures for fine particles. Once these measures have been implemented, we would expect to see an improvement in the respiratory health of the Australian population.Read moreRead less
Informing The Development Of A Model Of Care For Patients With End Stage COPD: What Are Their Needs And And They Being Met

Summary
Currently there is no specific model of care for people with end stage chronic obstructive pulmonary disease (COPD), despite growing evidence of the specific symptoms and issues of this patient group. Interviews with end stage COPD patients and their carers will be undertaken to explore the services currently being accessed, and how well patients’ needs are being met by these services. This project will conduct an audit of available services in South Australia and then examine how hospital, spec ....Currently there is no specific model of care for people with end stage chronic obstructive pulmonary disease (COPD), despite growing evidence of the specific symptoms and issues of this patient group. Interviews with end stage COPD patients and their carers will be undertaken to explore the services currently being accessed, and how well patients’ needs are being met by these services. This project will conduct an audit of available services in South Australia and then examine how hospital, specialist palliative care units and primary care services (including general practice) can interface to meet these identified patient and carer needs. The results from this study will be used to inform development of a distinct model (or models) of care that addresses the needs of patients with end stage COPD.Read moreRead less
Understanding Corticosteroid-sensitive And -insensitive Pathways In Airway Remodelling

Summary
Asthma and chronic obstructive pulmonary disease (COPD) are chronic disorders of the airways affecting millions of people worldwide. Airways become remodelled, or thickened, resulting in airway obstruction and decline in lung function. Approximately 400 asthmatics and 6000 COPD sufferers die in Australia each year. Worryingly, COPD is currently the fourth highest cause of death in Australia and this number is predicted to increase in the future. Unfortunately, the drugs currently available for c ....Asthma and chronic obstructive pulmonary disease (COPD) are chronic disorders of the airways affecting millions of people worldwide. Airways become remodelled, or thickened, resulting in airway obstruction and decline in lung function. Approximately 400 asthmatics and 6000 COPD sufferers die in Australia each year. Worryingly, COPD is currently the fourth highest cause of death in Australia and this number is predicted to increase in the future. Unfortunately, the drugs currently available for combating these diseases have limited success. We need to understand how to control airway remodelling to be able to improve treatments for asthma and COPD. But first we require a greater understanding of the molecular mechanism-s underlying the development of airway remodelling. With this proposal we will increase our knowledge of the mechanistic basis of asthma and COPD and may elucidate novel therapeutic targets for future pharmacological intervention.Read moreRead less
This application will allow me to restructure my work to provide sufficient time to do full justice to the current and planned commitments of our Respiratory Research Group. Our research programme includes the immunopathology of chronic airway diseases; the epidemiology of respiratory disease (TAHS); clinical physiology technology to service these studies; respiratory clinical pharmacology; microbe-host interactions in CF and COPD; and EBM in chronic respiratory disease self-management .
