Clostridium difficile infection in children hospitalized due to diarrhea

Area of Science:

• Pediatric Infectious Diseases
• Gastroenterology
• Microbiology

Background:

• Clostridium difficile infection (CDI) hospitalizations are rising, particularly among children.
• Understanding CDI prevalence, risk factors for severity, and strain characteristics in pediatric populations is crucial.

Purpose of the Study:

• To determine the extent of CDI in hospitalized children with diarrhea.
• To identify risk factors and predictors for severe CDI.
• To assess the prevalence of the NAP1 strain and compare CDI outcomes based on bacterial toxicity profiles.

Main Methods:

• Retrospective analysis of 64 pediatric patients diagnosed with CDI via polymerase chain reaction (PCR).
• Modified national adult guidelines were used to assess CDI severity.
• Data collected included patient demographics, prior antibiotic use, CDI acquisition (community vs. hospital), bacterial strain (NAP1, binary toxin-positive), and clinical outcomes.

Main Results:

• CDI accounted for 2.7% of pediatric diarrhea cases (13.5 per 1,000 admissions), with 52% community-associated.
• Antibiotic use preceded 95% of CDI cases.
• The NAP1 strain (binary toxin-positive) was present in 20.5% of cases and was associated with hospital-acquired infections and generalized illness.
• Risk factors for severe CDI included NAP1 infection (OR 4.85) and co-morbidities (OR 4.25).
• Severe CDI was also linked to diarrhea with ≥10 stools daily.
• Recurrence was low (4.5%), and no mortality was observed.

Conclusions:

• Clostridium difficile is a significant cause of antibiotic-associated diarrhea in hospitalized children.
• Co-morbidities and the NAP1 strain are key predictors of severe CDI in pediatric patients.
• Further research into pediatric CDI management and prevention strategies is warranted.
