Relationship of progression of radiographic changes in hands and wrists, clinical features and HLA-DR antigens in rheumatoid arthritis.
One hundred and twelve hospital based outpatients with rheumatoid arthritis (mean duration +/- standard error, 10.7 +/- 0.9 years) were studied for radiological progression of the hands and wrists over a mean period of 26.5 +/- 0.5 months. The majority were taking slow acting antirheumatic drugs (SAARD). The rate of radiographic progression was positively and independently associated with the female sex (p less than 0.01), erythrocyte sedimentation rate (ESR, p less than 0.05) and HLA-DR1 (p less than 0.05). There was a negative association with HLA-DR4 (p less than 0.05) but this was no longer significant after adjusting for ESR. There was no relationship between the rate of radiological progression and the presence of rheumatoid factor, rheumatoid nodules and duration of treatment with SAARD.
