Lung infections are the most frequent triggers of asthma exacerbations. While different infections cause exacerbations by they all result in the same type of lung inflammation. Using novel disease models, we have identified key molecules involved in a range of viral and bacterial induced asthma exacerbations. We will define these shared pathways that link viral and bacterial-mediated asthma exacerbations, thus these studies will pave the way for the development of unified treatments.
Web Based Study Of Risk Factors For Pain Exacerbation In Knee Osteoarthritis

Summary
While much is known about the risk factors for radiographic knee OA, the risk factors for symptoms emanating from joints affected by OA remain unclear. Identifying modifiable methods for alleviating pain and or avoiding risk factors for exacerbations of pain could have tremendous public health importance. In the proposed study we will use the Internet to facilitate data collection to test a set of risk factors for knee pain fluctuation among subjects with symptomatic radiographic knee OA.
Role Of Toll-like Receptor 7 In Rhinovirus-induced Asthma Exacerbation

Summary
One third of the annual asthma-related health care expenditure may be attributable to asthma-related hospitalisations. Even mild asthmatics experience severe exacerbations at a rate of almost one per year1 and those attacks can be fatal. Rhinovirus (RV) causes the majority of asthma exacerbations which may be linked to an impaired antiviral interferon (IFN) response in asthmatics. RV is sensed by Toll-like receptor (TLR) 7, but the role of this innate host defence pathway in regulating antiviral
Asthma is a common problem for women during pregnancy. There is concern about how asthma and its treatment may effect the baby, and also concern that asthma may deteriorate during pregnancy. Variable adherence to treatment compounds this situation. Current clinical measures are not very accurate in determining the correct dose of inhaled therapy to be used for asthma. However, there is now good evidence from clinical trials in nonpregnant adults and children that this situation can be improved b ....Asthma is a common problem for women during pregnancy. There is concern about how asthma and its treatment may effect the baby, and also concern that asthma may deteriorate during pregnancy. Variable adherence to treatment compounds this situation. Current clinical measures are not very accurate in determining the correct dose of inhaled therapy to be used for asthma. However, there is now good evidence from clinical trials in nonpregnant adults and children that this situation can be improved by using markers of inflammation to guide therapy. One of the promising tests of inflammation is exhaled nitric oxide. We wish to determine whether asthma can be better managed during pregnancy by using nitric oxide to guide therapy. We will examine whether this approach leads to fewer asthma exacerbations, lower doses of corticosteroid, better asthma control, and better outcomes for the baby. To do this we have put together a team with expertise across each of the important areas of asthma, pregnancy, and research methods. This will enable the study to provide a clear indication of which treatment approach is better, and this can then be offered to pregnant women and their health care team.Read moreRead less
Centre Of Research Excellence In Asthma Treatable Traits (CREATT)

Funding Amount
$2,500,000.00
Summary
This CRE will focus on personalised medicine in asthma, specifically using the treatable traits approach. We have identified disease management areas of highest importance to people with asthma and health care providers. We will generate new knowledge, develop and strengthen collaborations and train translation focused researchers to develop high quality evidence and translate this to practice.
Biomarkers To Define The Treatment End-point For Pulmonary Exacerbations In Cystic Fibrosis

Summary
Sensitive and reliable tests are required to monitor lung disease severity in cystic fibrosis. A number of potential methods have emerged in recent years. We will investigate how these tests track an acute episode of lung disease and determine whether, following a typical course of treatment, there is evidence of residual damage that contributes to overall progression of lung disease.

Summary
Severe Asthma remains a large burden for the Australian community. It does not respond to current management approaches. We will develop and implement a targetted therapy approach to severe asthma that will involve assessment of needs of people with severe asthma, community burden form severe asthma, biomarkers and linked treatment strategies, as well as knowledge transfer tools and training of the health and medical workforce.
Viral Infection And Exacerbations Of Asthma During Pregnancy: Characteristics, Mechanisms And Consequences

Summary
At least 12% of pregnant women in Australia have asthma and more than half of these women will experience an acute attack during pregnancy. This puts the fetus at risk of poor outcomes such as low birth weight or premature birth, which has a significant impact on their health in both the short term and long term. The mechanisms which lead to exacerbations of asthma during pregnancy are unknown, but have implications for the treatment of pregnant women with asthma. In non-pregnant adults, the maj ....At least 12% of pregnant women in Australia have asthma and more than half of these women will experience an acute attack during pregnancy. This puts the fetus at risk of poor outcomes such as low birth weight or premature birth, which has a significant impact on their health in both the short term and long term. The mechanisms which lead to exacerbations of asthma during pregnancy are unknown, but have implications for the treatment of pregnant women with asthma. In non-pregnant adults, the majority of asthma exacerbations are caused by viral infection and it is likely that a similar mechanism operates in pregnant women with asthma. No previous studies have identified the viruses responsible for exacerbations of asthma during pregnancy. We currently have a promising lead in this area, with data showing that one third of pregnant women with asthma have a severe exacerbation of their asthma requiring medical intervention during pregnancy, and a large proportion of these are likely to be due to viral infection. We propose that during pregnancy, pregnant women with asthma are more susceptible to viral infection than pregnant women without asthma. We also suggest that women with asthma will have more severe viral infections during pregnancy, and that these will contribute to the majority of acute asthma attacks during pregnancy. This project will determine the rate of infection among pregnant women with and without asthma and determine the viruses responsible for acute attacks of asthma during pregnancy. The study will also explore the inflammatory mechanisms which predispose women to viral infection. These results will contribute to a greater understanding of the mechanisms leading to exacerbations of asthma during pregnancy and will be used to develop more appropriate asthma monitoring and treatment strategies for pregnant women, which will have health benefits for both mother and baby.Read moreRead less
