[Basic therapy of rheumatoid arthritis. Comparison of methotrexate and sulfasalazine]

In a retrospective analysis a total of 167 patients with rheumatoid arthritis (RA) who had been treated with the basic therapy formulas of methotrexate (MTX) or sulfasalazine (SUL) were evaluated with respect to therapeutical result and side effects after a period of 12 months. There was no randomization as to either MTX (n = 87) or SUL therapy (n = 80), but deliberate use of therapy according to prior treatment and activity of the illness. Apart from a significantly higher number of inflammatory joint conditions in the MTX group there was no difference in the two patient groups at the beginning of the study. MTX treatment led clearly to a more conspicuous activity decrease of the illness (ESR, joint index) and a more favourable effect on the locomotor function. Furthermore, the sphygmomanometer readings (for grip strength determination), the dose reduction of the concomitant prednisolone medication as well as the doctor's opinion were in favour of MTX. The portion of patients who had to discontinue the therapy because of side effects (= 11%) and lack of effect (= 9%) was exactly identical in both groups of patients. Both substances have shown to be effective basic therapy formulas for rheumatoid arthritis, while methotrexate has a few advantages.
