Clostridium difficile infection after pediatric solid organ transplantation: a practical single-center experience

Area of Science:

• Pediatric Gastroenterology
• Infectious Diseases
• Transplant Medicine

Background:

• Global rise in Clostridium difficile infection (CDI) frequency and severity.
• Solid organ transplant (SOT) recipients are at increased risk due to immunosuppression.

Purpose of the Study:

• To investigate CDI occurrence and risk factors in immunocompromised pediatric patients, particularly SOT recipients.
• To analyze the clinical impact and outcomes of CDI in this vulnerable population.

Main Methods:

• Retrospective review of institutional databases at a German tertiary pediatric care center.
• Analysis of diagnostic tests for CDI in pediatric patients over a 3-year period.
• Inclusion of immunocompromised children, including kidney and liver transplant recipients.

Main Results:

• 797 tests in 343 patients; 104 CDI episodes in 69 patients.
• Pediatric SOT recipients represented 20% of CDI cases, with median onset 588 days post-transplant.
• Antibiotic exposure (>95% of cases) was the primary risk factor, especially in SOT patients.

Conclusions:

• CDI in pediatric SOT patients is associated with increased hospital stay and costs.
• Severe complications were rare, suggesting effective prevention through timely diagnosis and treatment.
• Early detection and management are crucial for preventing severe CDI courses in pediatric SOT recipients.
