Abstract: | ObjectiveTo analyze the safety of combined leflunomide (LEF), methotrexate (MTX), and glucocorticoid (GC) therapy, we investigated the adverse effects of such combination therapy in patients with early active rheumatoid arthritis (RA).MethodsTwo hundred sixty-six patients with RA who were receiving LEF and MTX therapy were randomly assigned to 3 groups, as follows: group 1 received no GC, group 2 received 7.5 mg prednisone, and group 3 received 15 mg prednisone. Adverse effects were analyzed using the χ2 test at week 4 or the Fisher exact test at week 12.ResultsPatients in group 1 had a higher incidence of skin rash, oral ulcers, leukopenia, and liver damage than did those in groups 2 and 3 (all, P ≤ 0.05). However, the rates of osteoporosis, diabetes, hyperlipidemia, and hypertension in group 3 were statistically higher than in groups 1 and 2 (P ≤ 0.05).ConclusionIn the treatment of RA, the incidence of skin rash, liver dysfunction, and oral ulcers may be decreased with combination therapy using LEF, MTX, and 7.5 mg prednisone, and blood pressure, blood glucose concentration, and bone density are not increased. Most important, 7.5 mg prednisone was synergistic with LEF and MTX, and such combination therapy could be a useful option as initial treatment of early active RA. |
