AI Article Synopsis

  • Carbohydrate antigen detection, nucleic acid probe detection, and bacterial culture are standard methods for confirming group A streptococcus (GAS) pharyngitis.
  • Testing mouth specimens for GAS has lower sensitivity compared to throat swab specimens.
  • The throat is the best site for sampling when diagnosing GAS pharyngitis.

Article Abstract

Carbohydrate antigen detection, nucleic acid probe detection, and bacterial culture are commonly used to confirm group A streptococcus (GAS) pharyngitis. Compared to standard throat swab specimens, the sensitivities of these tests with mouth specimens are poor. When testing for GAS pharyngitis, the throat remains the optimum site for sampling.

Introduction: Rapid and accurate detection of group A (GAS) pharyngitis allows for timely initiation of appropriate antibiotic treatment. This is important to prevent empiric antibiotic overuse while simultaneously lowering the risk of post-infection sequelae. Timely treatment may also reduce forward transmission, which could prevent cases of devastating invasive infections.

, also known as group A (GAS), is responsible for various conditions, such as pharyngitis, tonsillitis, necrotizing fasciitis, and streptococcal toxic shock syndrome (STSS). STSS, a rapidly progressing infection involving shock and multi-organ failure, was first reported in Japan in 1992, and since then, the number of cases has been steadily increasing. We herein report an autopsy case of STSS that resulted in sudden death.

The prevention and treatment of Rheumatic Heart disease is hinged on antibiotic administration in children with Group A (GAS) pharyngitis and Acute Rheumatic Fever (ARF). The Upper Limit of Normal (ULN) for serum Anti-streptolysin O titre (ASOT) has been employed as proof of antecedent GAS pharyngitis to fulfil the Jones' criteria for diagnosis of ARF. This value has not been generated among West African children.

Aim: This work describes the validation of an in-house extraction free real-time polymerase chain reaction (PCR) for the detection of Group A Streptococcus (GAS) in throat swabs collected in gel amies.

Method: Throat swabs received by the laboratory were prospectively tested by routine bacterial culture and an in-house PCR assay targeting the GAS SpeB gene with a multiplexed RNaseP internal control. Samples with discrepant culture/PCR results had additional testing using the commercial Xpert Group A Strep PCR assay (Cepheid).

Article Synopsis
  • A 71-year-old man experienced fever and joint pain after a recent throat infection, showing signs of group A streptococcal (GAS) infection with high antistreptolysin O (ASO) levels.
  • The case raised questions about whether he had acute rheumatic fever (ARF) or post-streptococcal reactive arthritis (PSReA), as he displayed symptoms of both conditions.
  • The authors highlight the need for careful consideration of ARF in patients with recent streptococcal infections and joint pain to ensure timely treatment and avoid complications.
