Group A Streptococcus (GAS) is a Gram-positive bacterial pathogen that causes an array of infectious diseases in humans. Accumulating clinical evidence suggests that proinflammatory interleukin (IL)-1beta signaling plays an important role in GAS disease progression.
Acute rheumatic fever (ARF) is an abnormal immune reaction following Streptococcus pyogenes (Strep A) infection of the throat, and likely the skin. Primary prevention is the prompt and appropriate antibiotic treatment of Strep A infection, and it can reduce the risk of developing ARF and subsequent rheumatic heart disease.
Summarising the current knowledge of Strep A transmission to humans will address gaps in the evidence and inform prevention and control strategies. The objective of this study is to evaluate the modes of transmission and attack rates of group A streptococcal infection in human populations.
Over 5 days, 120 schoolchildren from two schools in the remote Kimberley region of Australia were screened for Strep A pharyngitis. Molecular point-of-care testing identified Strep A pharyngitis in 13/18 (72.2%) symptomatic children. The portability and feasibility of molecular point-of-care testing was highly practical for remote settings.
"I had never heard of invasive Streptococcus A disease before, and I was shocked to hear that it is actually three times more common than meningococcal disease and just as deadly yet there is no vaccine to protect against it."
Group A Streptococcus causes a wide range of diseases from relatively mild infections including pharyngitis to more severe illnesses such as invasive diseases and rheumatic heart disease (RHD). Our aim is to estimate the cost-effectiveness of a hypothetical Strep A vaccine on multiple disease manifestations at the global-level.
Acute rheumatic fever (ARF), an autoimmune reaction to Group A Streptococcus (Streptococcus pyogenes; Strep A) infection, can cause rheumatic heart disease (RHD). New formulations of long-acting penicillins are being developed for secondary prophylaxis of ARF and RHD.
STopping Acute Rheumatic Fever Infections to Strengthen Health (STARFISH) brings together a diverse and multidisciplinary research team to investigate the most effective environmental health initiatives (EHIs) aimed at reducing Strep A infections and prevent Acute Rheumatic Fever (ARF).
Acute rheumatic fever is an immune-mediated condition triggered by Streptococcus pyogenes sore throat and possibly skin infection, with a substantial burden in resource-limited settings. Clinical decision rules (CDRs) are commonly used to guide antibiotic treatment of sore throat based on signs and symptoms, but their diagnostic accuracy varies by study and setting. This work aimed to assess the accuracy of multiple CDRs in Fiji to diagnose S. pyogenes sore throat.
