Hypothesis
Can serum IL-18 levels be used to monitor disease activity and treatment effectiveness in systemic juvenile idiopathic arthritis complicated by macrophage activation syndrome?
Conclusion
Monitoring serum IL-18 levels can be very useful in assessing and treating systemic juvenile idiopathic arthritis and its complication, macrophage activation syndrome.
Supporting Evidence
- The patient had severe macrophage activation syndrome but improved with treatment.
- Serum IL-18 levels were extremely high at the start but decreased with treatment.
- The patient remained in remission for two years after treatment was stopped.
Takeaway
Doctors can check a special protein called IL-18 in the blood to see how well a child with a serious arthritis condition is doing and if the treatment is working.
Methodology
The patient's serum IL-18 levels were monitored during treatment with corticosteroids, cyclosporin A, and NSAIDs.
Limitations
The study is based on a single case report, limiting generalizability.
Participant Demographics
A 22-month-old girl with systemic juvenile idiopathic arthritis.
