INTRODUCTION: The combination of methotrexate (MTX) + leflunomide (LFN) has been shown to be effective in the treatment of RA. Its safety has been questioned.
OBJECTIVE: To evaluate the effectiveness and safety of the combination of MTX + LFN in patients with active RA.
METHODS: This was a 24-week multicenter study, which included 88 patients with active disease despite consistent treatment with methotrexate and prednisolone.
RESULTS: We included 78 women (88%) and 10 men. The age was 51.3 ± 12.4 years, and the evolution of disease was 8 ± 6.8 years. Patients had active disease, which was indicated by a median of IQR of 10.0 (7.0-13.0) for swollen and of 14.0 (18.0-10.0) for tender joints for the whole group. The ACR responses achieved at week 24 were: ACR20: 76.0%; ACR50: 67.1%; ACR70: 23.9%. There was improvement in the activity of disease: DAS-28 score: 5.8 ± 1.2 at baseline vs. 3.8 ± 1.6 at week 24 (P = 0.000). The most significant adverse event was elevation of transaminases in eight patients (26%). Eight patients were withdrawn due to adverse events: four due to the elevation of transaminases, and one each due to diabetes insipidus, rash, diabetes mellitus and osteomuscular pain.
CONCLUSION: The combination of MTX + LFN is effective for treating RA in patients for whom conventional treatment has failed. Strict medical and laboratory control is to be enforced for safety.
