Streptococcus pyogenes, or group A Streptococcus (GAS), infections contribute to a high burden of disease in Aboriginal Australians, causing skin infections and immune sequelae such as rheumatic heart disease. Controlling skin infections in these populations has proven difficult, with transmission dynamics being poorly understood. We aimed to identify the relative contributions of impetigo and asymptomatic throat carriage to GAS transmission.
The social determinants of health such as access to income, education, housing and healthcare, strongly shape the occurrence of acute rheumatic fever and rheumatic heart disease at the household, community and national levels.
Secondary prevention of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) involves continuous antimicrobial prophylaxis among affected individuals and is recognised as a cornerstone of public health programmes that address these conditions. However, several important scientific issues around the secondary prevention paradigm remain unresolved.
The prevalence of group A streptococcal disease remains high among symptomatic individuals residing in Africa
This systematic review presents a critical, interpretive analysis of publications that include lived experiences of rheumatic heart disease
Rheumatic heart disease in pregnancy persists in First Nations people in Australia and New Zealand and is associated with major cardiac and perinatal morbidity
This chapter outlines the evidence and evolution of RHD control programs and draws conclusions about priorities following the 2018 World Health Organization Global Resolution on rheumatic fever and RHD.
Acute rheumatic fever and rheumatic heart disease disproportionately affect Aboriginal and Torres Strait Islander people in Australia, with devastating impacts on morbidity, mortality and community wellbeing. Research suggests that general practitioners and primary care staff perceive insurmountable barriers to improving clinical outcomes, including the need for systemic change outside their scope of practice.
Researchers from The Kids Research Institute Australia are joining forces with international experts in acute rheumatic fever (ARF) and rheumatic heart disease (RHD) to transform the diagnosis of these diseases thanks to an $US8 million grant from the Leducq Foundation.
Regular intramuscular benzathine penicillin G injections have been the cornerstone of rheumatic heart disease (RHD) secondary prophylaxis since the 1950s. As the pharmacological correlate of protection remains unknown, it is difficult to recommend changes to this established regimen. Determining the minimum effective penicillin exposure required to prevent Streptococcus pyogenes infection will accelerate development of new long-acting penicillins for RHD prevention as well as inform opportunities to improve existing regimens. The CHIPS trial will address this knowledge gap by directly testing protection afforded by different steady state plasma concentrations of penicillin in an established model of experimental human S. pyogenes pharyngitis.
