Clinico-serological profile of juvenile idiopathic arthritis.

We report clinico-serological profile of 210 children with Juvenile idiopathic arthritis (JIA), diagnosed as per ILAR classification criteria. Polyarticular, oligoarticular, and systemic onset disease was observed in 72, 69, and 40 children, respectively. The knee joint was the most frequently involved joint. Antinuclear factor and Rheumatoid factor were positive in 10 and 8, 6 and 20, and 7 and 7 percent children with polyarticular, oligoarticular, and systemic disease, respectively.
