Area of Science:

  • Pediatric infectious diseases
  • Microbiology
  • Diagnostic test evaluation

Background:

  • Streptococcal pharyngitis is a persistent public health concern in Vietnam.
  • Accurate diagnosis of streptococcal pharyngitis has been challenging in this region.
  • The need for reliable and rapid diagnostic tools is critical for effective patient management.

Purpose of the Study:

  • To evaluate the clinical performance of a rapid streptococcal antigen detection test (Quick-Vue Flex Strep A) in children with pharyngitis in Vietnam.
  • To compare the rapid test results against bacterial culture for accuracy.
  • To assess the convenience and acceptability of the rapid test in a clinical setting.

Main Methods:

  • A clinical trial involving 777 children diagnosed with pharyngitis at a hospital in Hanoi, Vietnam.

  • Parallel testing of throat swab specimens using the Quick-Vue Flex Strep A rapid test and bacterial culture.
  • Analysis of sensitivity, specificity, and clinical utility of the rapid test.

    • Main Results:

    • The rapid test demonstrated 89% sensitivity and 92% specificity compared to bacterial culture.
    • Specificity increased to 96% in children not previously treated with antibiotics.
    • The test was found to be convenient and acceptable to both patients and healthcare providers.

    Conclusions:

    • The Quick-Vue Flex Strep A rapid test is a sensitive and specific tool for diagnosing streptococcal pharyngitis in Vietnamese children.
    • Its ease of use and accuracy can facilitate appropriate antibiotic treatment, favoring penicillin over broad-spectrum agents.
    • Implementing this rapid test may contribute to reducing the incidence of antimicrobial resistance in the future.
