Antinuclear antibody studies in juvenile chronic arthritis.

Antinuclear antibody studies in juvenile chronic arthritis.

This study of children with chronic arthritis confirms that patients at greatest risk for chronic iridocyclitis have a young age of onset and positive antinuclear antibodies (ANA). Children who are ANA negative have a low risk of iridocyclitis. When it occurs it is at a significantly older age. No child developing juvenile chronic arthritis over 9, even with positive ANA, had chronic iritis. Th...

Antiphospholipid antibody associated thrombosis in juvenile chronic arthritis.

A child with systemic onset juvenile chronic arthritis (JCA) who developed a bilateral femuropopliteal vein thrombosis after plaster immobilisation following a tibial fracture is described. When the thrombosis was diagnosed, antiphospholipid antibodies detected either as lupus anticoagulant and anticardiolipin antibodies were found. This suggests that short term prophylatic antithrombotic treat...

Early-onset pauciarticular juvenile rheumatoid arthritis associated with human leukocyte antigen-DRw5, iritis, and antinuclear antibody.

Evidence has been sought for a genetically determined predisposition among children with juvenile rheumatoid arthritis (JRA) who are also at particular risk for the development of inflammatory eye disease.45 unrelated Caucasian patients (41 female) with early-onset pauciarticular JRA were human leukocyte antigen (HLA) types. 28 of the study group were found to be HLA-DRw5 compared with 16 of 84...

Eosinophil-specific and other granulocyte-specific antinuclear antibodies in juvenile chronic polyarthritis and adult rheumatoid arthritis.

Sera from 151 children of whom 112 had juvenile chronic polyarthritis (JCP), and from adults with rheumatoid arthritis (RA), and from healthy pregnant females were tested for the presence of granulocyte-specific antinuclear antibodies (GS-ANA). These were detected in 20% of sera from cases of JCP, in 68% of adult RA, but in none of the controls. Eosinophil-specific ANA were the only ANA present...
