Juvenile chronic arthritis in India: is it different from that seen in Western countries?

Medical records of 89 children with juvenile chronic arthritis attending the clinical immunology outpatient department of a tertiary care hospital were analysed. Polyarticular type of juvenile chronic arthritis was the most common, followed by pauciarticular and systemic onset types. No patient with the early onset pauciarticular disease subset, which is associated with iridocyclitis and antinuclear antibody (ANA) positivity was seen. Uveitis was observed in only one patient with late onset pauciarticular disease. The ANA positivity rate (1/89) was very low. Polyarticular onset type disease had a higher incidence of deformities.
