Insights
Ceftazidime-avibactam shows promise in treating carbapenem-resistant organism (CRO) infections in children, with high clinical response rates in both targeted and empiric therapy. This antibiotic combination is vital for improving survival and clinical outcomes in pediatric patients facing these challenging infections.
Area of Science:
- Pediatric Infectious Diseases
- Antimicrobial Resistance
- Pharmacology
Background:
- The incidence of carbapenem-resistant organism (CRO) infections is rising in pediatric populations.
- Pediatric-specific treatment guidelines for CRO infections are limited.
- Ceftazidime/avibactam is an effective antimicrobial agent against CRO isolates, but pediatric data are scarce.
Purpose of the Study:
- To evaluate the efficacy and safety of ceftazidime/avibactam in children with carbapenem-resistant organism infections.
- To assess clinical response and mortality rates in pediatric patients treated with ceftazidime/avibactam.
Main Methods:
- Retrospective study of pediatric patients (<18 years) treated with ceftazidime-avibactam.
- Data collected from 2020-2022 at the First Affiliated Hospital of Zhengzhou University.
- Analysis of confirmed and suspected CRO infections, including pathogen identification and treatment outcomes.
Main Results:
- 38 children were included; 20 had hematologic malignancies.
- 25 children with confirmed CRO infections (primarily CRE) showed an 84% clinical response rate and a 20% 30-day mortality rate.
- 13 children receiving empiric therapy had a 92.3% clinical response rate and no deaths.
Conclusions:
- Ceftazidime-avibactam demonstrates significant clinical efficacy in pediatric patients with CRO infections.
- The drug improves survival and clinical response rates in children, supporting its use in treating these difficult-to-treat infections.
Background:
The incidence of carbapenem-resistant organism (CRO) infections is increasing in children. However, pediatric-specific treatment strategies present unique challenges. Ceftazidime/avibactam is a β-lactam/β-lactamase inhibitor combination, showing adequate efficiency against CRO isolates. However, clinical data on the efficacy of ceftazidime/avibactam in children are still lacking.
Methods:
This was a retrospective study of children (aged <18 years) infected with confirmed or suspected carbapenem-resistant pathogens and treated with ceftazidime-avibactam at the First Affiliated Hospital of Zhengzhou University between 2020 and 2022.
Results:
We identified 38 children aged 14 (5.0-16.3) years; 20 (52.6%) had hematologic malignancies. 25 children with confirmed CRO infections were administered ceftazidime-avibactam as targeted therapy. The median treatment was 10 (6.0-16.5) days. Among them, 24 had infections caused by carbapenem-resistant Enterobacterales (CRE) (18 carbapenem-resistant Klebsiella pneumoniae and six carbapenem-resistant Escherichia coli species) and one with carbapenem-resistant Pseudomonas aeruginosa strains. The source of infection was the bloodstream in 60.0% of the cases (15/25). The clinical response rate was 84.0% (21/25), and 30-day mortality rate was 20% (5/25). 13 children were administered ceftazidime-avibactam as empiric therapy for suspected infections. The median treatment was 8 (6.0-13.0) days. No deaths occurred and clinical response was achieved in 12 of the 13 patients (92.3%) who empirically treated with ceftazidime-avibactam.
Conclusion:
Ceftazidime-avibactam is important for improving survival, and clinical response in children with infections caused by CRO.
