Insights
Cefditoren pivoxil effectively treated group A streptococcal infections in children, with most symptoms improving. However, some children experienced recurrent infections, indicating a need for further monitoring.
Area of Science:
- Pediatric infectious diseases
- Microbiology
- Pharmacology
Context:
- Group A Streptococcus (GAS) is a common bacterial pathogen in children.
- Antibiotic resistance and treatment efficacy are critical concerns for GAS infections.
- Cefditoren pivoxil is a third-generation cephalosporin antibiotic.
Purpose:
- To evaluate the clinical efficacy and bacterial eradication of cefditoren pivoxil in children with group A streptococcal infections.
- To assess the occurrence of recurrent infections and complications following treatment.
Summary:
- A prospective multicenter study evaluated 90 children with GAS infections treated with cefditoren pivoxil (9 mg/kg/day tid for 7 days).
- Clinical efficacy was observed in 79 children, with symptom amelioration.
- Four children had persistent GAS at therapy end, and 5 experienced recurrence within a month; isolates were identical to initial strains.
- No complications were reported, but 1 child experienced diarrhea.
Impact:
- Cefditoren pivoxil demonstrates clinical efficacy in treating pediatric GAS infections.
- Recurrence of GAS infection is possible despite initial treatment, necessitating follow-up.
- The study provides data on the safety and effectiveness of cefditoren pivoxil in a pediatric population.
Abstract:
Between October 2006 and April 2007, we enrolled 90 children with group A streptococcal infection in a prospective multicenter study. Children aged from 8 months to 12 years (6.2 +/- 2.2 years) treated with cefditoren pivoxil 9 mg/kg/day tid for 7 days were evaluated for clinical efficacy and bacterial effect at the end of therapy and were observed for the occurrence of recurrent infection and complications 4 weeks after the end of therapy. The most frequent T-types of 90 isolates were T1, T28, and T12 at 50.0%, 21.1%, and 11.1%. Of the 90, 11 did not return for follow-up. The 79 we evaluated clinical efficacy and their symptoms were ameliorated. Four still had GAS from pharyngeal swabs at the end of therapy. Isolates from them were identical to initial strains in T-type and PFGE pattern. All 78 observed within 1 month after the end of administration had no complications, but 5 had a recurrence of GAS infection. Two still had GAS from pharyngeal swabs at the end of therapy. Isolates from recurrence cases were identical to initial strains in T-type and PFGE pattern. Adverse effects were diarrhea observed in 1.
