Abstract

Insights

Mycoplasma pneumoniae (MP) was frequently detected in hospitalized children with acute respiratory infections. MP often co-occurred with other pathogens, particularly respiratory syncytial virus (RSV), impacting diagnoses like bronchiolitis.

Area of Science:

  • Pediatric infectious diseases
  • Molecular diagnostics
  • Respiratory infections

Context:

  • Mycoplasma pneumoniae (MP) infections are common in young children.
  • Acute respiratory infections (ARIs) necessitate hospitalization in pediatric populations.
  • Understanding the prevalence and co-detection of respiratory pathogens is crucial for effective management.

Purpose:

  • To describe the findings of molecular detection of MP in respiratory secretions of hospitalized pediatric patients with ARI.
  • To analyze the frequency of MP isolation in relation to age, sex, and co-infection with other respiratory pathogens.

Summary:

  • Molecular detection identified Mycoplasma pneumoniae as the most frequent microorganism (30%) in 919 hospitalized children with ARI.
  • Respiratory syncytial virus (RSV) was the second most common pathogen (25.1%).
  • MP was frequently detected alongside other pathogens (47.3%), most commonly RSV (31.3%), with significant differences in discharge diagnoses such as bronchiolitis.

Impact:

  • Highlights the significant prevalence of Mycoplasma pneumoniae in hospitalized pediatric patients with respiratory infections.
  • Underscores the frequent co-occurrence of MP with other respiratory pathogens, suggesting complex clinical presentations.
  • Emphasizes the need for further research into the clinical relevance of these co-infections in pediatric respiratory illnesses.
