The risk of intramuscular haematoma is low following injection of benzathine penicillin G in patients receiving concomitant anticoagulant therapy

Our local data supports continuing intramuscular injection of BPG in patients with rheumatic heart disease receiving anticoagulant medication

A population pharmacokinetic study of benzathine benzylpenicillin G administration in children and adolescents with rheumatic heart disease

Few children and adolescents receiving BPG as secondary prophylaxis will achieve concentrations >0.02 mg/L for the majority of the time between injections

Aboriginal children and penicillin injections for rheumatic fever: How much of a problem is injection pain?

We explore young Aboriginal people's and clinicians' experience of injection pain for the 10 years of penicillin injections young people are prescribed.

Establishing the lowest penicillin concentration to prevent pharyngitis due to Streptococcus pyogenes using a human challenge model (CHIPS)

The in-vivo plasma concentration of penicillin needed to prevent Streptococcus pyogenes pharyngitis, recurrent acute rheumatic fever, and progressive rheumatic heart disease is not known. We used a human challenge model to assess the minimum penicillin concentration required to prevent streptococcal pharyngitis.

High dose, subcutaneous injections of benzathine penicillin G (SCIP) to prevent rheumatic fever: A single arm, phase IIa trial of safety and pharmacokinetics

This Phase-IIa trial evaluates the safety and pharmacokinetics of high-dose, 10 weekly subcutaneous injections of penicillin (SCIP) in young people with a history of acute rheumatic fever (ARF).

Serological Responses to Target Streptococcus pyogenes Vaccine Antigens in Patients With Proven Invasive β-Hemolytic Streptococcal Infections

Rising incidence of invasive β-hemolytic streptococcal (iBHS) infections has prompted consideration of vaccination as a preventative strategy for at-risk populations. The benefits of a vaccine targeting Lancefield group A (Streptococcus pyogenes; Strep A) would increase if cross-species immunity against Lancefield groups C/G (Streptococcus dysgalactiae subspecies equisimilis; SDSE) and B (Streptococcus agalactiae; GBS) was demonstrated. 

The need for community-controlled tools to monitor health impacts of housing and living conditions in Australia

We explore the contemporary landscape of housing investments and initiatives seeking to improve health outcomes among Aboriginal and Torres Strait Islander people in Australia, as well as the dearth of quality evidence and agreed approaches to evaluation.

Estimating the true number of people with acute rheumatic fever and rheumatic heart disease from two data sources using capture-recapture methodology

In Australia, accurate case ascertainment of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) diagnoses for disease surveillance and control purposes requires the use of multiple data sources, including RHD registers and hospitalisation records. Despite drawing on multiple data sources, the true burden of ARF/RHD is likely to be underestimated.

Notification of acute rheumatic fever and rheumatic heart disease in hospitalised people in the Midwest region of Western Australia, 2012–2022: a retrospective cohort study

Acute rheumatic fever and rheumatic heart disease are caused by untreated group A streptococcus infections. Their prevalence is much higher among First Nations people than other Australians. 

Molecular analysis of human tick-bitten skin yields signatures associated with distinct spatial and temporal trajectories - A proof-of-concept study

Tick-associated diseases present challenges due to tridirectional interactions among host-specific responses, tick toxins and salivary proteins as well as microbes. We aimed to uncover molecular mechanisms in tick-bitten skin samples and contralateral skin samples collected simultaneously from the same participants, using spatial transcriptomics.
