Is rheumatoid arthritis becoming a milder disease ? Or are we starting second-line therapy in patients with milder disease ?
The aim of the study was to see whether rheumatoid arthritis (RA) is becoming a milder disease.
Information on the initial disease activity and patient function (modified Health Assessment Questionnaire-HAQ) was collected in all RA patients enrolled into studies of sulphasalazine since 1980 in two Glasgow teaching hospitals.
Patients (352) were enrolled in trials in the decade 1980-1989, and were compared to 374 patients enrolled in 1990-1994.
Patients recruited in the 1980s were significantly younger, but had a similar disease duration to the 1990s patients.
The 1980s patients had more active disease as measured by erythrocyte sedimentation rate (61 vs 44, P<0.0001) and C-reactive protein (40 vs 26, P<0.0001), and significantly worse function (HAQ 2.3 vs 1.9, P<0.001).
The response to sulphasalazine was very similar in the two cohorts, in terms of the percentage of patients remaining on therapy for 6 months, and the percentage improvement in measures of disease activity.
Patients with milder disease were enrolled into the more recent trials of sulphasalazine.
This may be because RA is becoming a milder disease, but other possible explanations are discussed.
