Summary
Influenza is an important infection that causes disease every year in the Australian population. People with lung disease are at particular risk to its effects. The ability of the virus to grow in birds and change its appearance to our immune system allows this virus to cause severe disease every year. We will examine the immune response to this virus in human cells, comparing this response to human and bird strains of the virus and see why subjects with lung disease are more susceptible.
Commercialisation Of A Glycoprofiling Diagnostic Kit And Novel Therapies For Biofilm Related Respiratory Disorders

Summary
Our preliminary studies have shown that a group of patients who suffer from chronic inflammatory disease and have bacterial biofilm identified on their mucosa have worse outcomes even after surgery. We have shown that they lack certain small protein and sugar molecules on their respiratory lining. We aim to use this technology as a diagnostic tool to aid the doctor in prescribing the appropriate treatment for these patients to prevent bacteria regrowing in their respiratory tract.
Clinical Impact Of Clonal Pseudomonas Aeruginosa In Cystic Fibrosis

Summary
In patients with cystic fibrosis (CF), the normal defence mechanisms are compromised by an inherent genetic fault which results in an extremely sticky and dehydrated mucus. The respiratory system is unable to eradicate microbes (infection) from the lungs of patients with CF which begin to multiply and cause infection and inflammation. Recurring infections are treated with multiple courses of antibiotics and frequent hospitalisation and eventually result in premature death. This study focuses on ....In patients with cystic fibrosis (CF), the normal defence mechanisms are compromised by an inherent genetic fault which results in an extremely sticky and dehydrated mucus. The respiratory system is unable to eradicate microbes (infection) from the lungs of patients with CF which begin to multiply and cause infection and inflammation. Recurring infections are treated with multiple courses of antibiotics and frequent hospitalisation and eventually result in premature death. This study focuses on the major bacterial problem, Pseudomonas aeruginosa. Several studies from Australia and the UK, including our own have shown that about 30% to 45% of patients share the same strain of Pseudomonas aeruginosa within a centre. We know that two dominant strains of Pseudomonas aeruginosa are found in CF centres on the eastern board of Australia. This is unexpected as this bacterium is usually acquired from the environment. The emergence of these clonal strains is causing increasing anxiety in the CF community. This study is designed to provide vitally needed information on the clinical implications of being infected by an clonal strain of Pseudomonas aeruginosa and the risk factors for the acquisition of an clonal strain. This new information will provide a rationale basis for the need for changes to infection control policies (including patient segregation), better outcome predictors for patients infected with clonal strain of Pseudomonas aeruginosa.Read moreRead less

Summary
Prof Hansbro’s group have developed world 1st experimental models of emphysema, severe asthma infection and lung cancer. He uses them to further our understanding of these untreatable diseases. This has led to the development of new potential therapeutic approaches. Now, in discovery programs he will expand studies of pathogenesis to identify new therapeutic targets these diseases. In development and translational programs he will progress new therapies towards clinical application.
Amoxycillin For Persistent Nasal Discharge In Rural And Remote Aboriginal Children: A Randomised Controlled Trial

Summary
Aboriginal children have the highest rates of acute and chronic respiratory diseases ever documented. While the underlying cause is socioeconomic disadvantage, the features of poverty that result in disease are not clear. Our current understanding of important risk factors like overcrowding, malnutrition and smoke exposure cannot completely explain the excessively high rates of disease seen in rural and remote Aboriginal communities. This randomised, double-blind, placebo-controlled clinical tri ....Aboriginal children have the highest rates of acute and chronic respiratory diseases ever documented. While the underlying cause is socioeconomic disadvantage, the features of poverty that result in disease are not clear. Our current understanding of important risk factors like overcrowding, malnutrition and smoke exposure cannot completely explain the excessively high rates of disease seen in rural and remote Aboriginal communities. This randomised, double-blind, placebo-controlled clinical trial will measure the impact of antibiotic treatment on persistent nasal discharge and rates of transmission of bacterial respiratory pathogens. An innovative study design will test the efficacy of twice daily doses of amoxycillin on newly developed clinical and bacteriological outcome measures. Both the investigators and the Aboriginal community have considerable experience in conducting this type of research and are committed to using a cooperative model of clinical research to reduce disease burden. Ongoing training of Aboriginal health workers in the principles of clinical epidemiology is an essential component of this process. This study will make an important contribution to the medical literature. Despite the deaths of around 10,000 children children from acute respiratory infections each day, very little is known about how antibiotics affect the transmission of some of the principal causative organisms. This project will greatly assist the development of appropriate antibiotic prescribing practices in high-risk populations.Read moreRead less
A New Non-invasive Diagnostic Technique Based On Detection Of Exhaled Respiratory Pathogens.

Summary
We developed a special collection mask and showed that the breath of people with colds or flu contains a tiny amount of virus. Currently, diagnostic samples are collected by putting a tube into the airways - this is very uncomfortable. Our masks may provide a new and more comfortable way to diagnose lung infections. We want to build better masks and ways to detect viruses and bacteria to test out this method. This may create a new test that will improve diagnosis and treatment.
