Understanding Group A Streptococcus in Children
Gene Expression in Isolates of Group A Streptococci Recovered From Patients Who Are Carriers
University of Wisconsin, Madison · NCT01558804
This study is trying to understand the differences in Group A strep bacteria between kids who are sick and those who carry the bacteria without symptoms, to help improve treatment options.

What this trial studies
This research aims to investigate the differences in Group A streptococcus (GAS) between children who are acutely infected and those who are carriers. The study will collect samples from children aged 5 to 15 years with acute pharyngitis and a positive test for GAS, comparing their transcriptional profiles and genetic sequences. By analyzing these samples, the researchers hope to uncover unique characteristics of GAS during acute infection versus carrier states, which could inform treatment approaches. The study will enroll approximately 180 participants to achieve its objectives.
Who should consider this trial
Good fit: Ideal candidates for this study are children aged 5 to 15 years who have a positive rapid antigen detection test for Group A streptococcus.
Not a fit: Patients who are unable to take beta lactam antibiotics or have other concurrent bacterial infections may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to better understanding and management of streptococcal infections in children, potentially reducing unnecessary antibiotic use.
How similar studies have performed: While this study explores a specific aspect of GAS infection, similar studies have shown promise in understanding bacterial behavior and treatment outcomes.
