Reports and Findings
Research
High dose, subcutaneous injections of benzathine penicillin G (SCIP) to prevent rheumatic fever: A single arm, phase IIa trial of safety and pharmacokineticsThis 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).
Research
Centralising Local Aboriginal Language and Culture in Healthy Skin Books on the See Treat Prevent (SToP) Trial in the Kimberley Region of Western Australia: A Process and Impact InquiryLanguage is significant for communicating knowledge across cultures and generations and has the power to attribute meanings and alter our worldviews.
Research
The need for community-controlled tools to monitor health impacts of housing and living conditions in AustraliaWe 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.
Research
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.
Research
Excess Deaths Associated with Rheumatic Heart Disease, Australia, 2013-2017During 2013–2017, the mortality rate ratio for rheumatic heart disease among Indigenous versus non-Indigenous persons in Australia was 15.9, reflecting health inequity. Using excess mortality methods, we found that deaths associated with rheumatic heart disease among Indigenous Australians were probably substantially undercounted, affecting accuracy of calculations based solely on Australian Bureau of Statistics data.
Research
The inequitable burden of infectious diseases among remote-living Aboriginal and Torres Strait Islander Australians: a product of historyAlthough Streptococcus pyogenes (Strep A) is the sixth-most common infectious disease globally, its transmission within the household remains an understudied driver of infection. We undertook a systematic review to better understand the transmission of Strep A among people within the home, while highlighting opportunities for prevention.
Research
Systematic Review of Household Transmission of Strep A: A Potential Site for Prevention That Has Eluded AttentionAlthough Streptococcus pyogenes (Strep A) is the sixth-most common infectious disease globally, its transmission within the household remains an understudied driver of infection. We undertook a systematic review to better understand the transmission of Strep A among people within the home, while highlighting opportunities for prevention.
Research
Perturbation of the T Cell Compartment Underlies Rheumatic Fever PathogenesisThis prospective cohort study, which recruited participants with definite ARF in Australia and Aotearoa New Zealand, profiled circulating immune molecules and cells to inform disease mechanisms and future druggable pathways.
Research
Streptococcus pyogenes pharyngitis elicits diverse antibody responses to key vaccine antigens influenced by the imprint of past infectionsKnowledge gaps regarding human immunity to Streptococcus pyogenes have impeded vaccine development. To address these gaps and evaluate vaccine candidates, we established a human challenge model of S. pyogenes pharyngitis. Here, we analyse antibody responses in serum and saliva against 19 antigens to identify characteristics distinguishing 19 participants who developed pharyngitis and 6 who did not.
Research
Recovery of culturable Streptococcus pyogenes from swabs stored at different temperaturesImproving our understanding of superficial Streptococcus pyogenes (Strep A) carriage and transmission necessitates robust sampling methods. Here, we compared the effect of storing swab samples in fridge (+4°C) and freezer (-20°C) conditions on the recovery of laboratory-cultured S. pyogenes.
