[HLA-DR in rheumatoid arthritis].

The authors describe the results of HLA-DR typing of 80 patients with rheumatoid arthritis (RA). The patients showed accumulation of HIA-DR (51.25% versus 28.9% in the control), with the relative risk being 2.58. The interrelationship is demonstrated between the clinical picture of RA and HIA-DR antigens: a statistically significant accumulation of HIA-DR4 in the seropositive patterns according to the RF of RA as compared with the seronegative pattern and primary demonstration of HIA-DR3 in RA with the systemic manifestations as compared with the articular pattern.
