Summary
Based on animal studies, we aim to demonstrate that the worsening of heart damage seen in patients with rheumatic heart disease (RHD) is due to repeated infections with bacteria (group A streptococci: GAS). The heart damage is caused by continual immune damage to the heart and valves and this has adverse effects on heart function. We will also investigate a novel way to prevent the development of RHD.
Evaluating The Genetic Contribution To Rheumatic Heart Disease Pathogenesis In Australian Aboriginal And Torres Strait Islander Communities

Summary
Rheumatic heart disease is highly prevalent in Aboriginal people in Australia and leads to early cardiac disease. Despite decades of research, the underlying genetic mechanisms for why it occurs are not well understood. We are conducting a genetic study to better understand why some people are susceptible to RHD and others are not. The study will involve substantial Aboriginal leadership and consultation and will be a model for the conduct of genetic studies in Aboriginal populations.
Rheumatic Fever Follow-up Study (RhFFUS) _ Determining The Optimal Clinical Response For Minor Heart Valve Abnormalities In An Indigenous Australian Setting

Summary
Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are a major health issue for Indigenous Australians. In a previous study heart ultrasounds in Aboriginal and Torres Strait Islander children frequently showed suspicious but not diagnostic changes. RhFFUS (Rheumatic Fever Follow-Up Study) aims to see if these changes are associated with a higher risk of ARF and progression to RHD. If this is the case these high risk children could be identified earlier and offered regular antibiotics ....Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are a major health issue for Indigenous Australians.

A National Population-based Study Of Rheumatic Heart Disease In Pregnancy

Funding Amount
$877,826.00
Summary
Whilst overall a rare disease, Indigenous peoples have disproportionately high rates of rheumatic heart disease (RHD). This study explores the prevalence and distribution of RHD in pregnancy in Australia and New Zealand. It details current management, diagnostic and referral process and risk factors. Key attributes of culturally safe models of care for RHD in pregnancy are explored, particularly as they relate to Indigenous women. Findings will inform policy, guidelines and education resources.
Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are a major problem for Australian Indigenous people. Accurate diagnosis of ARF allows for early preventive therapy with long acting penicillin, which can prevent RHD from developing or worsening. The aim of this study is to recruit a cohort of children and young people with ARF and apply the latest technologies to their blood samples, with the aim of developing a diagnostic test and open leads for potential new treatments.
A Targeted Molecular Approach To Treating Scabies And Associated Bacterial Infections.

Summary
Chronic infestation of human skin with parasitic scabies mites is a severe health burden in Australian Indigenous communities and other disadvantaged communities around the world. Secondary infections with bacteria exacerbate this skin problem, with long-term, systemic and often fatal consequences including rheumatic heart disease. Analyses of the scabies mite genome and associated bacteria will accelerate biomedical research toward improved treatment and control of this neglected disease.
Improving Delivery Of Secondary Prophylaxis For Rheumatic Heart Disease: A Stepped-wedge, Community-randomised Trial

Funding Amount
$1,913,074.00
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
Funder

Funding Amount
$960,655.00
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.
Using Metagenomics To Determine The Causative Agent(s) Of Tick-Borne Disease In Australia

Funding Amount
$639,428.00
Summary
Tick-borne disease has emerged as a topical and controversial public health problem in Australia. We will employ state-of-the-art techniques in metagenomics to determine what microbial species (bacteria, viruses and eukaryotes) circulate in Australian ticks and whether these or different microbes are also present in humans diagnosed with tick-borne disease. The data generated will provide key information on whether tick-borne disease has a microbiological cause and, if so, the microbes involved.
Evolution Of Pertussis Epidemics And Effect Of Genotypes On Infection Outcomes And Immunisation

Funding Amount

Summary
Pertussis, or whooping cough, is caused by Bordetella pertussis. Despite high vaccine coverage, the incidence of pertussis has increased substantially in recent years in Australia. One of the contributing factors is changes in the pertussis strains. This project will determine the genetic composition and virulence characteristics of epidemic strains in Australia and investigate the effect of these strains on disease severity and vulnerability of vaccinated individuals to infection.
