Serum antigammaglobulins in juvenile rheumatoid arthritis.

Serum immunoglobulins in juvenile rheumatoid arthritis.

Juvenile rheumatoid arthritis (JRA) differs in many aspects from its adult counterpart (Edstrom, 1958); one of the differences is a low incidence of positive sero-reactions for rheumatoid factors (RF) in patients with JRA (Bywaters, Carter, and Scott, 1959; Sievers, Ahvonen, Aho, and Wager, 1963; Ansell, 1966). Although the agglutinating activity of RF was found in different classes of immunogl...

Anticardiolipin Antibodies in Juvenile Rheumatoid Arthritis and Systemic Lupus Erythematosus

Background: Antiphospholipid antibody syndrome (APS) can either occur as a primary syndrome or associated with other autoimmune diseases such as systemic lupus erythematosus (SLE). Anticardiolipin antibody (aCL) of IgG and/or IgM isotype in blood, measured by a standardized ELISA is the most acceptable laboratory criteria. APS IgG isotype, particularly IgG2 subclass is more strongly associated ...

Monarticular juvenile rheumatoid arthritis.

Seven out of 22 children with monarticular juvenile rheumatoid arthritis (MJRA) developed involvement of other joints between six months and three and a half years from the onset. In the other 15 patients the disease has remained monarticular for between one and 16 years (mean six years). Chronic iridocyclitis was seen in three of the five boys, two with antinuclear antibodies. Children with MJ...
