Evaluation of 3-day azithromycin or 5-day cefaclor in comparison with 10-day amoxicillin for treatment of tonsillitis in children

Abstract

To evaluate the clinical efficacy of azithromycin, cefaclor, and amoxicillin in treatment of pediatric tonsillitis, a total of 256 children with Group A β-hemolytic streptococcus (GAS) tonsillitis were randomly divided into 3 groups. Only patients assessed with streptococcus-positive tonsillitis, considered to be compliant with treatment and complete clinical and microbiological evaluations at the end of therapy (day 14) and follow-up (day 30) were included in the efficacy analysis. Our study demonstrated that 96.4% of patients in the azithromycin group, 92.4% of patients in the cefaclor group, and 91.0% of patients in the amoxicillin group were recorded as clinical success at the end of therapy. Bacteriological eradication rates of the 3 groups at the end of therapy were 94.0%, 89.9%, and 88.5%, respectively. A pathogen recurrence rate was evaluated as 2.6%, 7.0%, and 5.9% at the follow-up. Treatment-stimulated adverse events occurred in 2.4% of patients in the azithromycin group, 11.3% in the cefaclor group, and 11.4% in the amoxicillin group. In summary, azithromycin showed an effective tendency for the treatment of pediatric tonsillitis with lower occurrence rate of adverse reactions, although there is no statistical significance for the clinical and bacteriological eradication efficacy between these 3 groups.
