Effect of antibiotic therapy on the clinical course of streptococcal pharyngitis
Insights
Antibiotic therapy, including penicillin V and cefadroxil, significantly improved clinical outcomes for children with group A beta-hemolytic streptococcal (GABHS) pharyngitis compared to placebo. This study highlights the effectiveness of antibiotics in treating strep throat symptoms.
Area of Science:
- Pediatrics
- Infectious Diseases
- Pharmacology
Background:
- Group A beta-hemolytic streptococcal (GABHS) pharyngitis is a common childhood infection.
- Antibiotic therapy is the standard treatment for GABHS pharyngitis.
- Understanding the comparative efficacy of different antibiotics is crucial for clinical practice.
Purpose of the Study:
- To evaluate the effect of antibiotic therapy on the clinical course of GABHS pharyngitis in children.
- To compare the efficacy of penicillin V and cefadroxil against placebo in treating GABHS pharyngitis.
Main Methods:
- A double-blind, randomized study involving 260 children.
- Children with confirmed GABHS pharyngitis were randomized to receive penicillin V, cefadroxil, or placebo.
- Clinical signs and symptoms were assessed before and after treatment.
Main Results:
- Significantly fewer children receiving penicillin V or cefadroxil showed persistent signs and symptoms compared to placebo.
- Physicians, parents, and patients reported greater overall clinical improvement in the antibiotic treatment groups.
- Both penicillin V and cefadroxil demonstrated superior efficacy over placebo.
Conclusions:
- Antibiotic treatment with penicillin V or cefadroxil is effective in improving the clinical course of GABHS pharyngitis in children.
- Early clinical improvement was significantly associated with antibiotic administration.
- These findings support the use of recommended antibiotics for GABHS pharyngitis.
Abstract:
We examined the effect of antibiotic therapy on the clinical course of group A beta-hemolytic streptococcal (GABHS) pharyngitis in 260 children. After a throat culture had been obtained, each child was evaluated for the presence of predetermined signs and symptoms, and was then randomized in a double-blind manner to receive penicillin V, cefadroxil, or placebo. Of the 194 children with throat cultures positive for GABHS, 68 received penicillin V, 70 received cefadroxil, and 56 received placebo. Approximately 18 to 24 hours later, each patient returned for reevaluation. Significantly fewer children who had received either penicillin or cefadroxil had persistence of each of the three objective signs and each of the three subjective symptoms than did children who had received placebo. In addition, the evaluating physician, parents, and patients all believed that significantly fewer of the patients given antibiotic failed to demonstrate overall clinical improvement.
