Summary
Children with enteric yersiniosis often develop reactive arthritis. Most cases resolve without lasting effects, though some may become chronic or mimic rheumatoid arthritis.
Area of Science:
- Pediatrics
- Rheumatology
- Infectious Diseases
Background:
- Enteric yersiniosis can lead to reactive arthritis in children.
- Long-term outcomes of this condition require further investigation.
Purpose of the Study:
- To evaluate the clinical and laboratory course of arthritis in children with enteric yersiniosis.
- To assess the long-term outcomes and potential complications of reactive arthritis following yersiniosis.
Main Methods:
- A seven-year follow-up study of 36 children diagnosed with enteric yersiniosis.
- Clinical evaluation and laboratory assessments of arthritis development and progression.
- Analysis of disease course, outcomes, and comparison with rheumatoid arthritis in select cases.
Main Results:
- Twenty-eight out of 36 children experienced an active, cyclical course of arthritis with favorable outcomes and no residual effects.
- Eight children had protracted (8-10 months) or chronic (over 12 months) arthritis, achieving clinical and laboratory remission.
- Three of these eight cases presented with symptoms similar to rheumatoid arthritis, with two confirmed by synovial biopsy.
Conclusions:
- Reactive arthritis following enteric yersiniosis in children typically has a favorable prognosis.
- A subset of patients may experience prolonged or chronic arthritis, occasionally resembling rheumatoid arthritis.
- Synovial biopsy can aid in the diagnosis of complex cases mimicking other arthritic conditions.
