Summary
Lyme disease can cause oligoarticular arthritis in children, sometimes without a rash. Early antibiotic treatment is effective for Lyme arthritis, preventing misdiagnosis as septic arthritis or juvenile rheumatoid arthritis.
Area of Science:
- Pediatric Rheumatology
- Infectious Diseases
- Immunology
Background:
- Lyme disease, a tick-borne illness, can manifest with joint inflammation.
- Oligoarticular arthritis in children presents a diagnostic challenge, often mimicking other rheumatologic conditions.
Observation:
- A study identified 25 pediatric cases of oligoarticular arthritis linked to Lyme disease.
- Many children lacked a history of erythema chronicum migrans (ECM) or other characteristic rashes.
- Symptoms included high fevers and, in some cases, neurological involvement like seventh nerve palsy preceding arthritis.
Findings:
- All patients tested positive for antibodies to the Lyme spirochete.
- Synovial fluid analysis revealed inflammatory markers consistent with infection.
- Antibiotic therapy, including oral administration, proved highly effective in resolving arthritis and preventing recurrence.
Implications:
- Lyme arthritis should be considered in the differential diagnosis of pediatric oligoarticular arthritis, especially in endemic areas.
- The absence of a rash does not rule out Lyme disease as a cause of arthritis.
- Timely diagnosis and antibiotic treatment are crucial for favorable outcomes in pediatric Lyme arthritis.
