The END RHD CRE: Developing An Endgame For Rheumatic Heart Disease In Australia

Funding Amount

Summary
Rheumatic heart disease (RHD) is caused by an abnormal immune reaction to some bacterial infections. Although RHD is rare in developed countries, Indigenous Australians still live with the burden of RHD. The END RHD CRE will explore risk factors for RHD, prevention with antibiotics, management of RHD and the potential for vaccine development. Individuals and communities experiencing RHD are integral partners to this work. The CRE will establish a strategy for ending RHD in Australia.
Improving Delivery Of Secondary Prophylaxis For Rheumatic Heart Disease: A Stepped-wedge, Community-randomised Trial

Summary
Rheumatic heart disease (RHD) is a major health problem in Indigenous communities. Continued progress in controlling RHD requires an understanding of how to improve delivery of regular injections of penicillin - secondary prophylaxis (SP). We will evaluate a systems-based approach to improving delivery of SP, using a stepped-wedge trial in 12 communities in NT and Qld. If successful, this model will provide a practical and transferable model.
Burden Of Rheumatic Heart Disease (RHD) And Impact Of Prevention Strategies: Comprehensive Evidence To Drive The RHD Endgame

Summary
Rheumatic heart disease is chronic damage to the heart valves caused by repeated bouts of acute rheumatic fever. Both are preventable, yet rates among Indigenous Australians are of the highest recorded. We propose to undertake the first multi-jurisdictional study of these conditions to determine trends in occurrence and evaluate the impact of existing interventions in Australia. Findings will be used to inform the development of a roadmap to remove RHD as a public health problem in Australia.
Breathing disturbances and reflexes in sleep and effects on sleep and daytime function. This project will investigate protective reflexes in sleep and the impact of breathing disturbances and frequent arousal on markers of brain functioning and health. This will also significantly advance the understanding of key mechanisms promoting unstable breathing in sleep and ill health and functioning from disturbed sleep.
Electrophysiological and Anatomical Characterization of the Coronary Sinus Musculature and its Relationship to the Atria. This series of experiments will characterise the normal coronary sinus musculature and its connectivity to the atria of the heart and establish their electrical relationships. The underlying characteristics of the muscular connections will also be evaluated with a view to possible future manipulations of the system. Understanding normal heart impulse propagation is paramount ....Electrophysiological and Anatomical Characterization of the Coronary Sinus Musculature and its Relationship to the Atria. This series of experiments will characterise the normal coronary sinus musculature and its connectivity to the atria of the heart and establish their electrical relationships. The underlying characteristics of the muscular connections will also be evaluated with a view to possible future manipulations of the system. Understanding normal heart impulse propagation is paramount before we can understand and develop treatments for dealing with heart problems. This information will facilitate the development of techniques to treat and prevent heart rhythm disorders that are a common cause of morbidity in the community.Read moreRead less
Functional characterisation of poly-histidine triad proteins. This project aims to understand the role and function of a novel family of surface proteins produced by Streptococci. These so-called polyhistidine triad proteins are known to contribute to capacity to cause disease in animals and humans, but we need to know how they work, as they may be excellent targets for novel drugs or vaccines.
Novel perspectives on the function of AB5 toxin B subunits in pathogenic bacterial. AB5 toxins are produced by bacteria that cause important diseases in humans and livestock. This project tests the hypothesis that the components of the toxins responsible for binding to host cells and tissues also directly contribute to cellular damage, thereby providing a better understanding of how AB5 toxin-producing bacteria cause disease.
Regenerating lizard tails: A model for understanding the process of lymphangiogenesis. In humans, impaired lymphatic drainage in limbs causes the debilitating swelling termed lymphoedema. Lymphoedema affects 500,000,000 people worldwide. In the developed world lymphoedema predominantly results from surgery for cancer, and occurs in approximately 25% of breast cancer patients. We will examine lymph vessel regeneration (lymphangiogenesis) in a naturally regenerating, complex structure (the lizard ....Regenerating lizard tails: A model for understanding the process of lymphangiogenesis.

In the developed world lymphoedema predominantly results from surgery for cancer, and occurs in approximately 25% of breast cancer patients. We will examine lymph vessel regeneration (lymphangiogenesis) in a naturally regenerating, complex structure (the lizard tail), to describe the regrowth process and determine the abundance, location, functional properties and molecular control of the new lymphatics. Furthermore, if reptilian lymphatic growth factors can promote lymphangiogenesis in mammals, we can design novel therapeutic approaches using reptilian ligands to promote lymphangiogenesis in lymphoedematous human tissues.Read moreRead less
A single vaccine for influenza and pneumonia. Influenza and bacterial pneumonia collaborate to kill millions of people each year. This project aims to develop a single vaccine that will provide long-lasting protection against both influenza and pneumonia.

Summary
Streptococcus pneumoniae is a human-only bacterium that is responsible for killing more than one million people every year. This project will analyse how the human immune system fights this bacterium, and subsequently, how the bacteria manages to subvert these attacks and survive in the human host. This will provide crucial information for developing new drugs against this pathogen, in an attempt to combat the ever-increasing problem of antibiotic resistance.
