Clinical and laboratory studies of levamisole in patients with rheumatoid arthritis.

Two studies with levamisole in rheumatoid arthritis are reported. In the first study of 30 patients levamisole was superior to placebo in terms of pain relief, reduction in articular tenderness, duration of morning stiffness, erythrocyte sedimentation rate (ESR), and radioisotope uptake in knee and wrist joints. There were no consistent differences in lymphocyte function, immunoglobin or complement concentration, or polymorphonuclear granulocytic function. In the second study forty patients were commenced on treatment with either gold or levamisole. At the end of one year there were significant improvements with both regimens in pain score, joint tenderness and ESR. The patients on levamisole showed significant improvement of duration of morning stiffness, while the patients on gold showed significant improvement of rheumatoid factor titre and left hand grip, but there were no significant differences between the two regimens.
