title: beta2-glycoprotein I in rheumatoid arthritis.
abstract: Serum beta2-glycoprotein I of the patients with rheumatoid arthritis was studied by means of single radial immunodiffusion method. There was a significant lowering of beta2-glycoprotein I concentration in patients with rheumatoid arthritis. An inverse proportional correlation was seen between the concentrations of beta2-glycoprotein I and of alpha1-antitrypsin, and between the former and C-reactive protein (CRP) rates in individual specimens. Slightly positive relationship was observed between the concentrations of beta2-glycoprotein I and of alpha2-HS glycoprotein. The beta2-glycoprotein I concentrations in healthy adults were significantly higher than those of previous reports.
