Insights
Tigecycline showed good outcomes and tolerability in critically ill children with multidrug-resistant gram-negative infections. Further trials are needed to confirm these findings in pediatric populations.
Area of Science:
- Pediatric infectious diseases
- Antimicrobial stewardship
- Critical care medicine
Background:
- Limited pediatric data exists for tigecycline in treating multidrug-resistant gram-negative bacterial infections.
- This study evaluates tigecycline's effectiveness and safety in critically ill children.
Purpose of the Study:
- To assess clinical outcomes and tolerability of tigecycline in pediatric patients with multidrug-resistant infections.
- To identify predictors of treatment success and mortality.
Main Methods:
- Retrospective cohort study of 143 pediatric patients treated with tigecycline.
- Analysis included clinical success rates, infection-related mortality, and laboratory assessments for tolerability.
- Logistic regression and Cox modeling were used to identify predictors.
Main Results:
- Clinical success was achieved in 76.9% of patients, with *Klebsiella pneumoniae* and *Acinetobacter baumannii* being the most common pathogens.
- Intensive care admission and combination therapy were associated with treatment failure.
- Infection-related mortality was 28.7%, with intensive care admission as the only independent predictor; no significant organ toxicity was observed.
Conclusions:
- Tigecycline demonstrated favorable outcomes and acceptable tolerability in critically ill children with multidrug-resistant infections.
- Limitations include the retrospective design and lack of a control group.
- Prospective trials are recommended to validate these findings.
Background:
Pediatric data on tigecycline for multidrug-resistant infections caused by gram-negative bacteria remain scarce. We described clinical outcomes and tolerability of tigecycline in critically ill children at a single tertiary center.
Research Design And Methods:
In this retrospective cohort study, 143 pediatric patients receiving tigecycline (1-1.2 mg/kg or 50 mg twice daily) between January 2018 and September 2023 were analyzed. Most patients (72.0%) required intensive care; 66.4% received combination therapy. Primary outcome was clinical success (infection resolution with marker normalization). Logistic regression and Cox modeling assessed success and mortality predictors; Kaplan-Meier curves compared survival. Paired laboratory data assessed tolerability.
Results:
Klebsiella pneumoniae (72.0%) and Acinetobacter baumannii (17.5%) predominated; 87% of isolates displayed carbapenem resistance. Clinical success reached 76.9%. Intensive care admission and combination therapy independently predicted failure. Overall infection-related mortality was 28.7%; intensive care admission was the sole independent mortality predictor. Paired laboratory values showed no significant hepatic, pancreatic, or hematological changes; one biliary sludge event was recorded.
Conclusions:
Tigecycline, a glycylcycline antimicrobial, was associated with favorable outcomes and acceptable tolerability in children with multidrug-resistant infections. The single-center retrospective design, absence of a control group, and frequent concomitant antibiotic use limit generalizability; prospective trials are needed.
