Juvenile rheumatoid arthritis in Auckland: a long term follow-up study with particular reference to uveitis

Although features of juvenile rheumatoid arthritis (JRA) have been well described in British, American, and to a lesser extent Australian communities we can find no previous study of the clinical characteristics of this disease in a New Zealand population or indeed in any population containing Polynesians. In a follow-up study of 55 Auckland residents with juvenile rheumatoid arthritis, current information was obtained for 78% of the study group with a mean interval from disease onset to follow up of 9.3 years. The outcome for the group as a whole was excellent although patients with a polyarticular course, regardless of onset subtype, had a poorer outcome with respect to both ongoing disease activity and functional disability. Polynesian patients were represented in all onset subtypes in proportion to their frequency in the general community and there was no recognisable influence of race on the course of the disease. Despite careful ophthalmological examination only one case of mild uveitis was detected, a much lower incidence than in British and American reports.
