The immune system is highly likely to play an important role in the progression of this condition, because of the frequency of respiratory infections that occur.

The immune system is highly likely to play an important role in the progression of this condition, because of the frequency of respiratory infections that occur. We will examine in detail the immune response of COPD patients, examining specific genes and proteins that are important in the defence against bacteria. Blood samples will be obtained from people with COPD who are stable. We will then obtain further blood samples when there is a flare-up of the lung condition, and during recovery. We will compare the results from the blood samples, with variations in the genes that people carry. Information about individual differences in the body's response to infection would help us to better understand how COPD develops, and to initiate research on new methods of diagnosis and treatment of COPD.Read moreRead less
Preventing Complications Of Chronic Obstructive Pulmonary Disease
Funder

Funding Amount
$310,914.00
Summary
Chronic obstructive pulmonary disease (COPD) is a devastating lung disease that affects smokers. Lung complications and complications in other organs occur commonly. This study will examine factors that lead to exacerbations of COPD, and test the effectiveness of early diagnosis of coronary artery disease using CT scans.
Testing The Lung Microbiome To Predict Risk Of Frequent Exacerbations In COPD

Funding Amount
$666,052.00
Summary
Chronic obstructive pulmonary disease (COPD) is a disease of global importance. Exacerbations, mostly due to respiratory infection, are complications that lead to significant illness. This study will characterise the communities of microbes in the lung, and use this information to predict frequency of exacerbations of COPD measured over 12 months.

This project is about a new idea to treat severe asthma, chronic obstructive lung disease (COPD) and sudden worsening of these diseases (exacerbations). Asthma and COPD are very common. Asthma afflicts approximately 10 % of all Australians and kills approximately 700 annually. COPD will be the third most common cause of death worldwide by 2010 (WHO) and costs more that $ AUS 10 Billion annually. The highest risk of death and greatest costs are associated with severe asthma and exacerbations.

Asthma afflicts approximately 10 % of all Australians and kills approximately 700 annually. COPD will be the third most common cause of death worldwide by 2010 (WHO) and costs more that $ AUS 10 Billion annually. The highest risk of death and greatest costs are associated with severe asthma and exacerbations. Our idea, which is based on extensive animal data, is that these diseases can be treated by blocking the activity of proteins that allow a cell called the lung macrophage to grow, become activated, proliferate and survive. These proteins are called CSF-1 and GM-CSF and they belong to a larger class of proteins called colony stimulating factors (CSFs) Macrophages are important because they can rapidly respond to bacteria, viruses and fungi that can infect the lungs of asthma and COPD patients. Infections cause exacerbations. Normally, macrophages release a number of molecules called mediators that rouse a strong defensive reaction- a process called innate immunity. For example macrophages signal for a cell type called the neutrophil, which is a very efficient bacteria killer, to flood into the lung. However, these same cells can cause serious lung damage if the response is too strong or persistent. Macrophages and neutrophils need CSFs to work properly so blocking CSFs prevents lung damage. Although we now already know that blocking CSFs can prevent and reverse lung inflammation we still need to know a great deal more in order to know if this approach will be useful to treat people in the future. Our project is therefore all about understanding the fine detail of how CSFs can damage the lung. The importance of the project is that our work may lead to entirely new, and much more effective, treatments for people suffering from asthma and COPD.Read moreRead less
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
