Reactive Arthritis Following Clostridium difficile Colitis in a 3-Year-Old Patient

Area of Science:

• Pediatric Rheumatology
• Infectious Diseases
• Gastroenterology

Background:

• Reactive arthritis following Clostridium difficile (CD) colitis is increasingly recognized in adults.
• Twenty adult cases have been documented in medical literature.
• This condition is rarely reported in pediatric patients.

Purpose of the Study:

• To report the first pediatric case of reactive arthritis following CD colitis.
• To describe the clinical features and outcomes of this condition in a child.
• To compare pediatric and adult presentations of reactive arthritis post-CD colitis.

Main Methods:

• Case report of a 3-year-old patient.
• Review of clinical presentation, diagnostic findings, and treatment.
• Comparison with existing literature on adult cases.

Main Results:

• The patient, a 3-year-old, developed reactive arthritis after CD colitis.
• Clinical features were similar to adult cases, including asymmetric oligoarticular arthritis of lower extremities.
• Arthritis onset was 1-2 weeks post-diarrhea, with resolution in weeks to months.

Conclusions:

• Reactive arthritis following CD colitis can occur in children, though likely less common than in adults.
• Pediatric cases may present with fewer mucocutaneous manifestations.
• Gastrointestinal pathogens are more frequent triggers in children compared to genitourinary organisms.
