Clostridium difficile in young children. Association with antibiotic usage

Area of Science:

• Microbiology
• Pediatrics
• Infectious Diseases

Background:

• Clostridium difficile is an opportunistic pathogen.
• Antibiotic use is a known risk factor for C. difficile infection.
• The prevalence and clinical significance in young children are not fully understood.

Purpose of the Study:

• To investigate the prevalence of Clostridium difficile in hospitalized children aged 0-2 years.
• To compare C. difficile carriage in children with and without diarrhea.
• To identify risk factors and clinical outcomes associated with C. difficile in this age group.

Main Methods:

• Stool samples were collected from 52 children with diarrhea and 52 controls.
• C. difficile was isolated by stool culture.
• Toxin detection was performed.
• Antibiotic history and follow-up data were collected.

Main Results:

• C. difficile was isolated from 21% of children with diarrhea and 33% of controls (no significant difference).
• Children with C. difficile had significantly higher prior antibiotic use (p < 0.001).
• Toxin was detected in 1 diarrhea case and 5 controls. C. difficile cleared in most children within 4-6 months, with persistence linked to further antibiotic exposure.

Conclusions:

• Clostridium difficile is frequently present in the stools of young children.
• Prior antimicrobial therapy is associated with increased C. difficile carriage.
• Most C. difficile carriage states are asymptomatic in children under two years old.
