Age, C-reactive protein, and hospital stay Are associated with switching from azithromycin to doxycycline in pediatric macrolide-resistant Mycoplasma pneumoniae pneumonia
To evaluate the role of Mycoplasma pneumoniae resistance gene detection in guiding antibiotic therapy, emphasizing that it does not independently guide therapy, and to identify predictors for switching antibiotics in children with pneumonia.
Key Findings:
91.3% of participants tested positive for macrolide resistance genes.
Increased age, elevated C-reactive protein (CRP), and prolonged hospital stay were identified as independent predictors for switching to doxycycline.
Significant differences in baseline characteristics and clinical management were noted between the switch and maintenance groups.
Interpretation:
Resistance gene detection alone does not guide antibiotic switching; however, elevated CRP and older age are early indicators of the need for switching, highlighting the importance of integrating these factors into clinical decision-making.
Limitations:
The study is retrospective and may be subject to biases inherent in such designs.
Clinical decisions were based on physician judgment rather than a standardized protocol.
Findings may have limited generalizability due to the specific geographic focus of the study.
Conclusion:
Clinical decisions should integrate biomarkers like CRP and age alongside resistance gene testing to optimize treatment strategies for Mycoplasma pneumoniae pneumonia in children.
