Infection with Clostridioides difficile ribotype 046 in a paediatric liver transplant patient

Area of Science:

• Microbiology
• Pediatric Gastroenterology
• Infectious Diseases

Background:

• Clostridioides difficile is a significant cause of hospital-acquired diarrhea, often linked to antibiotic use and weakened immune systems.
• Pediatric Clostridioides difficile infections (CDIs) are increasing globally, yet molecular characterization data in children remains limited.
• Liver transplant recipients are particularly vulnerable to infections due to immunosuppression.

Observation:

• A female pediatric patient, who underwent a liver transplant at 7 months of age, developed a Clostridioides difficile infection.
• Clinical data and molecular characteristics of the infecting C. difficile strain were analyzed.
• The specific strain identified was the 046 ribotype.

Findings:

• The 046 ribotype, previously unassociated with pediatric diarrhea, was identified as the causative agent in this case.
• This finding expands the known spectrum of C. difficile ribotypes implicated in pediatric infections.
• The clinical presentation and management of this rare pediatric CDI were documented.

Implications:

• This case highlights the importance of considering C. difficile in immunocompromised pediatric patients, including transplant recipients.
• The identification of the 046 ribotype in a pediatric case warrants further investigation into its prevalence and virulence in children.
• Enhanced molecular surveillance of C. difficile strains in pediatric populations is crucial for understanding transmission and guiding treatment strategies.
