Summary
Cell-free microbial DNA (cfDNA) testing in children showed a 30.4-41.8% efficiency in guiding therapeutic decisions. This molecular diagnostic tool identified pathogens missed by conventional methods, aiding in clinical management.
Area of Science:
- Pediatric Infectious Diseases
- Molecular Diagnostics
- Microbial Genomics
Background:
- Cell-free microbial DNA (cfDNA) analysis is an emerging diagnostic tool.
- Its clinical utility in pediatric settings requires further investigation.
Purpose of the Study:
- To evaluate the impact of cfDNA testing on therapeutic decisions in pediatric patients.
- To determine the diagnostic yield and efficiency of cfDNA in a children's hospital.
Main Methods:
- Retrospective analysis of 80 cfDNA tests performed on 59 children.
- Assessment of cfDNA results for their contribution to clinical management and diagnosis.
Main Results:
- cfDNA identified at least one microbial agent in 57% of tests (45/79).
- Results were contributory to therapeutic decisions in 30% (24/79) and diagnostic in 19% (15/79).
- cfDNA detected pathogens missed by conventional methods in 27.8% (22/79) of cases.
Conclusions:
- The overall efficiency of cfDNA testing ranged from 30.4% to 41.8%.
- cfDNA testing offers valuable diagnostic information, sometimes surpassing conventional techniques in pediatric care.
