Insights
Procalcitonin (PCT) guided therapy significantly reduces antibiotic duration and adverse events in pediatric infectious diseases. This approach appears effective in decreasing antibiotic exposure, though further large-scale studies are recommended.
Area of Science:
- Pediatric Infectious Diseases
- Clinical Microbiology
- Pharmacology
Background:
- Antibiotic overuse contributes to antimicrobial resistance and adverse events.
- Biomarkers like procalcitonin (PCT) can guide antibiotic stewardship.
- Pediatric infectious diseases require careful management to balance efficacy and safety.
Purpose of the Study:
- To evaluate the impact of procalcitonin (PCT)-guided therapy on antibiotic exposure in pediatric patients with infectious diseases.
- To synthesize evidence from randomized controlled trials (RCTs) on PCT-guided antibiotic management.
- To assess the effect of PCT guidance on antibiotic duration, adverse events, and clinical outcomes.
Main Methods:
- An updated systematic review and meta-analysis of four RCTs involving 1,313 pediatric patients.
- Searches conducted across major databases including MEDLINE, Embase, and Cochrane.
- Trial sequential analysis (TSA) used to calculate required information size (RIS) and assess the robustness of findings.
Main Results:
- PCT-guided antibiotic therapy was associated with a significantly shorter duration of antibiotic treatment (-2.22 days) compared to standard care.
- A decreased rate of antibiotic-related adverse events was observed in the PCT-guided group (RR, 0.25).
- No significant differences were found in hospital stay, antibiotic prescription rates, readmission, or mortality.
Conclusions:
- Procalcitonin (PCT)-guided management effectively reduces antibiotic exposure in pediatric infectious diseases.
- The findings suggest a potential benefit in decreasing antibiotic duration and associated adverse events.
- Larger prospective clinical studies are necessary to confirm these results and further elucidate the role of PCT in pediatric infectious disease management.
Objective:
We aimed to evaluate the effect of procalcitonin (PCT) guided therapy on antibiotic exposure in pediatric patients with infectious disease.
Methods:
We performed an updated systematic review and meta-analysis of randomized controlled trials (RCTs) identified in systematic searches of MEDLINE, Embase, the Cochrane Database, Google Scholar, and SinoMed (through July 2021). The primary outcome was the length of the antibiotic therapy. Required information size (RIS) was calculated using trial sequential analysis (TSA).
Results:
Four RCTs with 1,313 patients with infectious disease were included. Overall, after a mean 22-day follow-up, PCT-guided antibiotic therapy was associated with a significantly shorter length of antibiotic therapy compared with the control group (WMD, -2.22 days; 95% CI, -3.41 to -1.03; P <0.001) and a decreased rate of antibiotic adverse events (RR, 0.25; 95% CI, 0.11-0.58; P <0.001). However, the length of hospital stay (WMD, -0.39 days; 95% CI, -0.84 to 0.07; P = 0.094), rates of antibiotic prescription (RR, 1.10; 95% CI, 0.97-1.25; P = 0.122), hospital readmission (RR, 1.03; 95% CI, 0.92-1.16; P = 0.613) and mortality (RR, 0.73; 95% CI, 0.17-3.19; P = 0.674) were comparable between the PCT-guided antibiotic and control groups. TSA showed that the RIS was 2,340, indicating a statistically significantly shorter length of antibiotic therapy between PCT-guided antibiotic and control groups (P <0.05).
Conclusions:
PCT-guided management seems to be able to decrease antibiotic exposure in patients with infectious disease. However, much larger prospective clinical studies are warranted to confirm these findings.
