Group A β-hemolytic Streptococcal Pharyngitis: An Updated Review

Area of Science:

• Pediatric Infectious Diseases
• Bacteriology
• Clinical Microbiology

Background:

• Group A ß-hemolytic Streptococcus (GABHS) is the primary bacterial cause of acute pharyngitis in pediatric populations globally.
• Clinical presentation alone is often insufficient for definitive diagnosis.

Purpose of the Study:

• To provide clinicians with comprehensive information on the clinical features, diagnostic approaches, and management strategies for GABHS pharyngitis.
• To emphasize the importance of accurate diagnosis and timely treatment.

Main Methods:

• A literature search was performed in December 2022 using "group A β-hemolytic streptococcal pharyngitis" in PubMed Clinical Queries.
• The review focused on research published within the last ten years.

Main Results:

• GABHS pharyngitis symptoms include fever, sore throat, dysphagia, pharyngeal inflammation, tonsillar erythema, uvular edema, and cervical lymphadenopathy.
• Microbiologic confirmation via throat swab is recommended for suspected cases before antibiotic initiation.
• Clinical scoring systems (Centor, McIssac) aid in identifying patients needing diagnostic testing, reducing unnecessary antimicrobial use.
• Penicillin V and amoxicillin are first-line treatments; alternatives include cephalosporins, clindamycin, clarithromycin, and azithromycin based on allergy status.

Conclusions:

• Prompt diagnosis and antimicrobial therapy are essential to prevent suppurative and non-suppurative complications, including rheumatic fever.
• Effective treatment reduces symptom severity, illness duration, and disease transmission.
