Rheumatoid factor positive, oligoarticular onset juvenile rheumatoid arthritis.
We describe 2 children with oligoarticular onset juvenile rheumatoid arthritis (JRA) with early erosive disease. Both patients were rheumatoid factor (RF) positive, but neither had HLA-DR4. These findings suggest RF is associated with early erosive disease, independent of HLA-DR4. RF positive oligoarticular onset JRA should probably be recognized as a separate subgroup of JRA.
