Clostridium difficile Colonization Before and After Hospitalization in Children

Area of Science:

• Pediatric Infectious Diseases
• Microbiology
• Hospital Epidemiology

Background:

• Clostridium difficile infection (CDI) incidence and severity have increased globally since the early 2000s.
• CDI development requires gastrointestinal flora disruption and microorganism ingestion.
• Hospitalized children represent a vulnerable population for CDI colonization.

Purpose of the Study:

• To investigate Clostridium difficile colonization in hospitalized children.
• To identify pre-hospitalization risk factors associated with colonization on admission.
• To assess the impact of hospital-acquired factors on colonization at discharge.

Main Methods:

• Study included 106 pediatric patients (2-18 years) with diverse hospital diagnoses.
• Stool samples were collected on admission and discharge.
• C. difficile toxin A/B was detected in stool samples.

Main Results:

• Overall C. difficile toxin A/B positivity was 24.5% and 48.1% in hemato-oncology patients.
• Pre-hospitalization antibiotic use and underlying diseases correlated with C. difficile colonization on admission.
• Data on discharge colonization factors were collected.

Conclusions:

• Toxigenic C. difficile colonization is highly prevalent in hospitalized children.
• Hemato-oncology patients exhibit a significantly higher colonization rate.
• Early identification of risk factors is crucial for managing CDI in pediatric hospital settings.
