Summary
Adult-onset Still's disease presents with fever, rash, and polyarthritis. Elevated serum ferritin is a key diagnostic marker, and moderate steroid doses are effective for treatment.
Area of Science:
- Rheumatology
- Immunology
Context:
- Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disorder.
- Historically linked to Still's original description of Juvenile Rheumatoid Arthritis (JRA).
Purpose:
- To outline the key clinical and laboratory features of Adult-onset Still's disease.
- To highlight diagnostic markers and effective therapeutic strategies for AOSD.
Summary:
- AOSD is characterized by spiking fevers, evanescent rash, and polyarthritis.
- Distinguishing features include chronic polyarthritis with ankylosis (joint fusion) rather than destructive changes, unlike Rheumatoid Arthritis (RA).
- Key laboratory findings include elevated Erythrocyte Sedimentation Rate (ESR), leukocytosis, liver dysfunction, and markedly increased serum ferritin levels.
Impact:
- Increased serum ferritin serves as a crucial indicator of disease activity and a diagnostic marker for AOSD.
- Early diagnosis, guided by characteristic fever and rash, is essential.
- Moderate-dose corticosteroids are the primary and most effective treatment modality for AOSD.
