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.

Rheumatic Heart Disease

Rheumatic heart disease (RHD) is the most important cause of acquired cardiovascular disease in children and young adults. Virtually non-existent in most of Australia, it still predominantly affects Aboriginal communities.

Early rheumatic heart disease is a recognized intermediate on the pathway to advanced rheumatic heart disease

Rheumatic heart disease is a major cause of premature cardiovascular morbidity and mortality globally. Over the past decade, echocardiographic screening has changed our understanding of the natural history of RHD, revealing a high burden of clinically silent, mild RHD among people who cannot recall a history of preceding acute rheumatic fever. This viewpoint outlines the evidence that this earliest form of rheumatic heart disease, only detectable through echocardiographic screening, is an intermediate stage that many, but not all, individuals may pass through on the pathway to advanced rheumatic heart disease.

Acute rheumatic fever

Acute rheumatic fever is an autoimmune disorder resulting from Group A Streptococcus pharyngitis or impetigo in children and adolescents, which may evolve to rheumatic heart disease (RHD) with persistent cardiac valve damage. RHD causes substantial mortality and morbidity globally, predominantly among socioeconomically disadvantaged populations, with an interplay of social determinants of health and genetic factors determining overall risk.

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).

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.

NEARER SCAN (LENO BESIK) evaluation of a task-sharing echocardiographic active case finding programme for rheumatic heart disease in Australia and Timor-Leste

Rheumatic 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.

Carol's story: losing a parent to RHD

After being diagnosed with rheumatic heart disease at ten, Elizabeth had to leave country and her family for a large chunk of her childhood so she could be treated in Adelaide.

Margie's story: Parent to a child with ARF

When Liana complained of a sore foot and showed signs of a fever, her mum Margie rushed her to hospital. An X-ray of her foot revealed no obvious injury, so she was sent home and advised to take painkillers.

Impact of mitral regurgitation on left ventricular remodeling and function in children with rheumatic heart disease

The impact of mitral regurgitation from pediatric rheumatic heart disease and its effect on left ventricular remodeling and function following surgical intervention is uncertain. The objective is to explore the impact of mitral valve surgeries on myocardial mechanics, remodeling and function and identify pre-operative predictors of post-operative dysfunction which may contribute to the optimal timing of intervention.
