Abstract:
In a 12-month double-blind placebo-controlled trial, the effect of sulphasalazine was studied in 40 patients with ankylosing spondylitis. The treatment group showed significant improvement in pain, stiffness, sleep disturbance (p less than 0.05), finger/floor distance, erythrocyte sedimentation rate, C-reactive protein, orosomucoid and IgA levels (p less than 0.01). There was improvement in sleep disturbance (p less than 0.05), finger/floor distance and erythrocyte sedimentation rate (p less than 0.01) in the placebo group. Sulphasalazine did not retard radiological progression as measured either by plain X-ray or computerised tomographic scans. Multiple analysis of variance did not show a significant difference in disease activity indicators between the 2 groups.
