Reports and Findings
Research
Transmission potential of Streptococcus pyogenes during a controlled human infection trial of pharyngitisControlled human infection (CHI) models can provide insights into transmission of pathogens such as Streptococcus pyogenes (Strep A). As part of the Controlled Human Infection with Penicillin for Streptococcus pyogenes (CHIPS) trial, we explored the potential for transmission among participants deliberately infected with the Strep A emm75 strain.
Research
NEARER SCAN (LENO BESIK) evaluation of a task-sharing echocardiographic active case finding programme for rheumatic heart disease in Australia and Timor-LesteRheumatic heart disease (RHD) is underdiagnosed globally resulting in missed treatment opportunities and adverse clinical outcomes. We describe the protocol for a study which aims to co-design, implement and conduct an evaluation of a task-sharing approach to echocardiographic active case finding for early detection and management of RHD in high-risk settings in Australia and Timor-Leste.
Research
Costs of primary healthcare presentations and hospital admissions for scabies and related skin infections in Fiji, 2018–2019Scabies and related bacterial skin and soft tissue infections are highly prevalent in many tropical, low- and middle-income settings. These skin conditions contribute to higher healthcare costs and burdens on healthcare systems.
Research
Trimodal skin health programme for childhood impetigo control in remote Western Australia (SToP): a cluster randomised, stepped-wedge trialSkin infections affect physical health and, through stigma, social-emotional health. When untreated, they can cause life-threatening conditions. We aimed to assess the effect of a holistic, co-designed, region-wide skin control programme on the prevalence of impetigo.
Research
Housing Initiatives to Address Strep A Infections and Reduce RHD Risks in Remote Indigenous Communities in AustraliaThis research sought to provide an outline of identified household-level environmental health initiatives to reduce or interrupt Strep A transmission along each of these pathways.
Research
Morbidity of Scabies in Resource-Limited Countries: Rheumatic Heart Disease (RHD) and Post-Streptococcal Glomerulonephritis (APSGN)Scabies is one of the world’s most prevalent diseases, with approximately 147 million cases at any one time and an estimated annual incidence of 455 million new episodes. Although Group A streptococcal (GAS) pharyngitis has long been implicated in the pathogenesis of acute rheumatic fever (ARF) and subsequent rheumatic heart disease (RHD), impetigo caused by GAS has recently been postulated as a link between scabies and the pathogenesis of ARF.
Research
Securing the supply of benzathine penicillin: a global perspective on risks and mitigation strategies to prevent future shortagesBenzathine benzylpenicillin is a globally indispensable medicine.
Research
Tonsils at Telethon: developing a standardised collection of tonsil photographs for group A streptococcal (GAS) researchGroup A streptococcus (GAS) infections, such as pharyngitis and impetigo, can lead to rheumatic fever and rheumatic heart disease (RHD). Australian Aboriginal and Torres Strait Islander populations experience high rates of RHD and GAS skin infection, yet rates of GAS pharyngitis are unclear.
Research
"Hurts less, lasts longer"; a qualitative study on experiences of young people receiving high-dose subcutaneous injections of benzathine penicillin G to prevent rheumatic heart disease in New ZealandHere we describe the experiences of young people living with ARF participating in a Phase-II trial of SubCutaneous Injections of BPG.
Research
Overlapping Streptococcus pyogenes and Streptococcus dysgalactiae subspecies equisimilis household transmission and mobile genetic element exchangeStreptococcus dysgalactiae subspecies equisimilis and Streptococcus pyogenes share skin and throat niches with extensive genomic homology and horizontal gene transfer possibly underlying shared disease phenotypes.
