Clostridium difficile Enterocolitis and Reactive Arthritis: A Case Report and Review of the Literature

Area of Science:

• Pediatric Rheumatology
• Pediatric Infectious Diseases
• Gastroenterology

Background:

• Reactive arthritis is an uncommon complication of Clostridium difficile enterocolitis, particularly in pediatric populations.
• The pathophysiology and clinical course in children remain incompletely understood.

Purpose of the Study:

• To review existing pediatric cases of Clostridium difficile reactive arthritis.
• To present a new case and discuss clinical presentation, treatment, and outcomes.
• To emphasize the importance of considering Clostridium difficile in children with relevant symptoms.

Main Methods:

• Literature review of 6 previously reported pediatric cases.
• Detailed reporting of a seventh pediatric case, including medical history, symptoms, diagnostic findings, and treatment.
• Clinical follow-up of the presented case.

Main Results:

• The seventh case involved a 6-year-old boy who developed diarrhea and asymmetric polyarthritis post-antibiotic treatment for an upper respiratory infection.
• Stool culture confirmed Clostridium difficile.
• Treatment with nonsteroidal anti-inflammatory drugs and metronidazole led to complete resolution of symptoms.
• No recurrence was observed during a 12-month follow-up period.

Conclusions:

• Clostridium difficile reactive arthritis in children typically follows a self-limiting course.
• Diagnostic consideration of Clostridium difficile should be routine in pediatric patients presenting with gastrointestinal issues and acute joint pain.
• Prompt diagnosis and appropriate treatment can effectively manage symptoms.
