Determination Of Disease Specific Epitopes In Rheumatic Heart Disease In Australia

Funding Amount
$374,817.00
Summary
Rheumatic Fever and Rheumatic Heart Disease (RF-RHD) remain a significant cause of illness in Aboriginal communities in Australia. RF-RHD is a complication which follows infection with a specific bacterium. The purpose of this study is to compare the body's response and find out the patterns of antibody and immune cell reactivity to the bacterium and body proteins in RF-RHD patients and controls. It will also enable us to study the mechanisms that initiate the disease process.

Summary
Dengue viruses are carried by mosquitoes and infect millions of people around the world, particularly in tropical countries of SE Asia, Central and South America, Africa and recently in Australia (North Queensland and NT). There is no vaccine or drug available for preventing or treating the infections, which are characterised by severe illness that involves inflammation and fevers that can sometimes be fatal. This proposal focuses on a virus specific enzyme.

There is no vaccine or drug available for preventing or treating the infections, which are characterised by severe illness that involves inflammation and fevers that can sometimes be fatal. This proposal focuses on a virus specific enzyme. This enzyme (called a protease) is essential for the virus to multiply and so it is a potential target for new drugs that can bind to it and block its function. We have produced and purified this viral enzyme in the laboratory and now propose to design, synthesize, and develop the first drugs for the treatment of humans infected with dengue virus. We plan to do this by examining the action of the enzyme, determining its three dimensional structure, and using computers and chemical methods to obtain very powerful blockers of enzyme action. These drug candidates will be tested against the enzyme, against cells infected with virus, and in rats to find out if they can be administered by mouth or by injection and if they have any toxic side effects. This project will provide valuable information about how to develop drugs to stop dengue fever and its associated illnesses.Read moreRead less
Identification Of Molecular And Cellular Pathways Predicting Susceptibility Or Resistance To Severe Dengue Fever
Funder
National Health and Medical Research Council
Funding Amount
$761,481.00
Summary
This cooperative research project aims to undertake a comprehensive immunological and molecular analysis of individuals with mild versus severe dengue fever recruited at local hospitals in Jakarta, Indonesia. The project will uncover key processes responsible for the development of severe disease. This information will identify specific biomarkers for innovative diagnostic tools for early prediction/detection of cases that will progress to complicated dengue.
Modelling The Impact Of Global Climate Change On The Epidemiology Of Infectious Diseases In Bangladesh

Funding Amount
$118,988.00
Summary
Climate change may impact on human health via a change in the distribution and pathogenicity of infectious diseases, particularly in the South Asian region. This study will use high quality environmental and clinical data from an established time-series collated in Bangladesh, to better inform mathematical models which may predict future changes in infectious diseases epidemiology. Accurate and valid modelling can be valuable in guiding future public health policy for vulnerable populations.
Australian Predicting Infectious ComplicatioNs In Children With Cancer (PICNICC) Project
Funder
National Health and Medical Research Council
Funding Amount
$694,980.00
Summary
Children undergoing cancer treatment are at an increased risk of infection. This is managed by admission to hospital for antibiotics which can be a frightening experience for the child, disruptive for their family and expensive for the healthcare system. While many need admission, a proportion of patients can be safely managed at home with oral or intravenous antibiotics. This project aims to identify these children, so as to improve their quality of life, and decrease cost of treatment.
