There is a continuing search for improved and more targeted treatments. We have been studying a cytokine called interleukin-4 which can suppress the production by blood cells of many of the inflammatory mediators that initiate and maintain inflammation. With the recognition that interleukin-4 has this anti-inflammatory activity on blood cells, there was considerable optimism that this molecule may not only be a natural regulator of inflammation but also used in immunotherapy. However we do not know how this molecule downregulates inflammatory blood cells. It will be necessary to know this if it is to be used in human gene therapy for treatment of inflammatory diseases. Cells must be activated before a molecule which is anti-inflammatory can be effective. Different cell types from different inflammatory sites will be studied to better characterise different activation pathways. How interleukin-4 regulates these pathways will be studied. Once identified, treatments based on the properties of interleukin-4 may be designed-optimised.Read moreRead less

Summary
Chronic Obstructive Pulmonary Disease (COPD) is a chronic disease that can progress to severe disability and use of hospital services. It is an important cause of both death and disability in Australia. Specifically it is the third leading cause of disease burden after heart disease and stroke. Smoking is the most important cause of the disease and there is strong evidence that smoking cessation will largely prevent progression of COPD. National evidence based guidelines for management of COPD w ....Chronic Obstructive Pulmonary Disease (COPD) is a chronic disease that can progress to severe disability and use of hospital services. It is an important cause of both death and disability in Australia. Specifically it is the third leading cause of disease burden after heart disease and stroke. Smoking is the most important cause of the disease and there is strong evidence that smoking cessation will largely prevent progression of COPD. National evidence based guidelines for management of COPD were published in 2003 but these need to be implemented in the community. General practice is well placed to have a key role in early intervention and evidence based management of COPD. There is evidence that specialised nurses working in collaboration with GPs can improve the care the chronic illnesses including COPD. Care Plans with input from health professionals from a range of disciplines have been recommended for COPD but there are barriers to implementing these in general practice. This project brings together nurse assistance and care planning in a model of care designed to deliver best practice management of COPD in the community. The aim of this research is to evaluate the impact of anurse and GP partnership for care of COPD. We will examine the effect on quality of care and health outcomes at 6 and 12 months follow up. Our hypothesis is that the use of a nurse to work as a team with the patient and GP to develop and implement a care plan based on clinical practice guidelines will improve the quality of care received and have a beneficial effect on the patients' respiratory and overall health. This research will be of major significance for improving COPD care in the community and will have far reaching implications for both policy and practice. It will also define a new role for nurses and GPs working in partnership.Read moreRead less
