Jeong: Assessment of Disease Activity in Juvenile Idiopathic Arthritis

Abstract

Juvenile idiopathic arthritis (JIA) is a chronic inflammation of joints in pediatric patients. Assessment of JIA disease activity is very difficult, because children cannot definitely describe their pain by themselves due to development of cognitive function during the pediatric period. Assessment of JIA disease activity is useful for quantitative measurement of patient status, monitoring therapeutic response, and disease course over time. This article reviewed objective assessment tool for JIA disease activity and described differences in assessment between adult rheumatoid arthritis and JIA.
