One hundred eighty-nine patients with rheumatoid arthritis were entered into a prospective, controlled, double-blind multicenter trial comparing placebo amd methotrexate (MTX).721 bles measured, including joint paidtenderness and swelling counts, rheumatoid nodules, and patient and physician assessment of disease activity. MTX treatment demonstrated statistically significant improvement over placebo in patients with anemia, elevated erythrocyte sedimentation rate, and rheumatoid factor. However, nearly one-third of the patients receiving MTX were withdrawn for adverse drug reactions, of which elevated levels of liver enzymes was the most common. Pancytopenia occurred in 2 patients taking MTX. All adverse drug effects resolved without sequelae. MTX appears to be effective in the treatment of active rheumatoid arthritis but requires close monitoring for toxicity.

Thirty-seven patients with psoriatic arthritis were entered into a 12-week prospective, controlled, double-blind multicenter trial comparing placebo and oral pulse methotrexate therapy. Methotrexate was given in a dose of 2.5-5.0 mg every 12 hours in 3 consecutive doses per week. A stable background medication program with nonsteroidal antiinflammatory drugs was allowed. Methotrexate was superior to placebo only in physician assessment of arthritis activity and in improvement of the amount of skin surface area with --

Health status measures are conceptually relevant to the assessment of clinical outcome in the rheumatic diseases, but their ability to detect meaningful changes in health has not been clearly demonstrated. This report describes the performance of a self-administered health status questionnaire in a randomized, double-blind, 21-week comparison of placebo, oral gold, and injectable gold in rheumatoid arthritis patients. Outcome was assessed by standard clinical measures, including joint count, grip strength, and laboratory tests, and by the Arthritis Impact Measurement Scales, a reliable and valid health status measure that assesses physical dis-
