Streptococcal Pharyngitis Clinical Trial
Official title:
Diagnostic Accuracy of Rapid Molecular Tests for Group A Streptococcal Pharyngitis Using Saliva Samples: Prospective Multicenter Study in Primary Care
Observational study evaluating the diagnostic accuracy of rapid point-of-care molecular Group A strep diagnostic tests in saliva as compared to standard culture- and PCR-based techniques for the management of children aged 3-15 years of age presenting with sore throat to primary care.
Group A streptococcus (GAS) is found in 20% to 40% of cases of childhood pharyngitis; the remaining cases are viral. Streptococcal pharyngitis ('strep throat') deserves antibiotics, while these are not indicated in viral cases. Because signs and symptoms of streptococcal and viral cases overlap, most guidelines recommend relying on a diagnostic test to identify Group A streptococcus to select who should receive antibiotics. In most settings, the first-line test to detect Group A Streptococcus is a rapid antigen detection test based on a throat swab, and the reference standard to identify streptococcal cases is throat culture. Recently, new rapid tests were developed. They use molecular techniques, such as rapid PCRs or LAMP, based on throat swabs. We hypothesize that these new molecular tests are sensitive enough to be performed on saliva swabs instead of throat swabs. Collecting saliva is less invasive and could be done by personnel with limited training. ;
